Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shackle-type suspending device, and more particularly to a shackle-type suspending device capable of preventing bending of a shackle so that a hanging load is not limited to a vertical direction and can cope with a hanging load in any direction such as a horizontal direction. The present invention relates to a novel shackle-type hanging device capable of inserting and removing a shackle pin with one touch and preventing the shackle pin from dropping out during use.

[0002]

2. Description of the Related Art In general, shackles, which are widely used as hanging brackets for cargo and materials in cargo handling work, civil engineering work and construction work, are provided with holes at both ends of a U-shaped main body. A shackle pin that penetrates these holes and is secured with a nut that is screwed to the thread at the tip of the bolt, and a screw is engraved in one of the holes of the shackle body. With a shackle pin screwed directly onto
There are types. It is widely used as a connection between a shackle and a shackle, a connection between a shackle and a wire rope, or a connection to a material or an instrument having a hole. Therefore, at the time of these connections, the shackle pin consisting of the bolt, nut or pin screw is unscrewed and removed from one end of the main body, and then another shackle or the like is passed through the shackle pin. An attaching / detaching operation, such as penetrating through the portion and screwing, is required.

[0003]

However, the work of loosening or tightening the bolt, nut or pin screw as a shackle pin is complicated,
If the tightening force is too weak, or if the work is subject to torsion or impact, there is a danger that the bolt, nut, or pin screw will rotate and come off the screw part. In order to avoid such danger, after the nut is fastened, the cotter pin is passed through the threaded portion of the bolt in the transverse direction so that the nut cannot be rotated, or the head of the pin screw is treated to prevent falling off. Occasionally, it became more and more complicated in relation to the work of inserting and removing pins.

Further, when a load such as a horizontal direction is applied to the shackle (a load in a direction in which the opening of the shackle is opened), the shackle pin or the shackle body is broken or detached, and the suspended load is removed. Therefore, it has been required that the shackle is always used only in a state where the hanging load is always in a direction perpendicular to the shackle pin.

In recent years, shackles have also been widely used for suspending supporting steel materials used in construction work such as digging work, in which case the method of using the shackle may be problematic. The supporting steel material is a long load-bearing beam having a cross section mainly of T or H type, and as shown in FIGS. 17 and 18, holes 24 are drilled at appropriate intervals in a longitudinal edge, A shackle pin is inserted through the hole to prevent the shackle from coming off, and another shackle, hook or wire rope is inserted through the shackle and lifted by a crane or the like.

That is, as shown in FIG.
Reference numeral 5 denotes a metal fitting made on the assumption that the shackle body 26 in the direction orthogonal to the shackle pin consisting of the bolt 27 and the nut 29 should be used in a state where a load is applied thereto. Hanging support 23
When the work is carried out in a state of being suspended horizontally, another shackle 28 or the like is connected to the shackle 25, and the hanging rope direction is perpendicular to the longitudinal direction of the shackle body 26 with a wire rope suspended from the crane. There is no use other than hanging up and down like this. Therefore, when the supporting steel material is hung horizontally or obliquely, a problem deviating from the intended use occurs, and other metal fittings must be used. That is, the shackle body 26
Is a U-shaped bracket, and when a load is applied in the direction in which the U-shaped shackle body 26 opens, the shackle 25 bends, and a concentrated load acts on the shackle body and the pin screw, which may cause breakage. This is because the property becomes higher.

As another metal fitting, there is, for example, a clamp. This clamp is also a U-shaped metal fitting similar to a shackle, and is suspended in a state in which an edge of a supporting steel material or the like is fitted into its opening and chucked. Because it supports, its safe use is accompanied by various restrictions. That is, although the clamp is also a U-shaped fitting, it does not bend until a predetermined load is applied in the direction in which the U-shape is opened, and therefore it is safe unless the predetermined load and the selection of the hanging direction are erroneously selected. However, unlike a shackle, there is no member to be directly connected to the supporting steel, such as a shackle pin, just by chucking the edge of the supporting steel, so careful selection of the lifting direction is necessary, and lifting work is required. Requires experience and skill.

Therefore, in the present invention, when a shackle is used, there is no need to turn a bolt, a nut, or a pin screw as a shackle pin, and it is not necessary to take any measures to prevent the shackle from falling off. The present invention provides a shackle-type hanging device having a simple structure, and a shackle-type hanging device that is safe even when used in a state where horizontal or diagonal suspension is likely to bend.

[0009]

SUMMARY OF THE INVENTION A shackle-type hanging device according to the present invention comprises a U-shaped shackle body, a shackle pin inserted through pin holes formed in enlarged portions at both ends thereof, and a shackle body. And a slider that movably fits and prevents the U-shaped shackle body from opening. Therefore, the slider prevents the shackle body having the U-shape from opening, so that the supporting steel material can be suspended horizontally or obliquely. In addition, the slider can slide the shackle body, so that the slider can be moved without any trouble at the time of attaching / detaching or turning operation of the shackle pin.

A U-shaped shackle body, a shackle pin inserted into pin holes formed in enlarged portions at both ends thereof, and a U-shaped shackle body slidably fitted to the shackle body. And a cam portion that is rotatable eccentrically with a shaft at one end of the shackle pin, and the shaft penetrates the shackle pin rotatably in the axial direction. A configuration in which an operation handle is pivotally mounted on the other end, and a lock pin, a slope hole for engaging and disengaging the lock pin, and a slope hole diametrically opposed to the slope hole are formed on the relative surface between the operation handle and the head of the shackle pin. I will provide a.

[0011] Therefore, the operation handle is rotated clockwise perpendicular to the axial direction of the shaft through the knob portion to disengage the lock pin and the slope hole, and the cam portion is decentered from the shackle pin by rotating. The shackle pin can be prevented from coming out by rotating the shackle pin so that the cam portion can be removed from the pin hole by rotating the cam portion to the same diameter as the shackle pin. In addition, since the slider prevents the shackle body having the U-shape from opening, the support steel material can be suspended horizontally or obliquely. Further, the slider can slide the shackle body, so that the slider can be moved without any trouble at the time of attaching / detaching or turning operation of the shackle pin.

Further, the present invention provides a configuration in which a key screw protruding into one of the pin holes is screwed into the enlarged portion, and a key groove is formed in the outer peripheral surface of the shackle pin in the axial direction. Therefore, when the shackle pin is pulled out from the other pin hole, the shackle pin is prevented from falling off on one pin hole side and does not fall off.

[0013] Further, there is provided a structure for preventing co-rotation of the shackle pin by a notch formed in the head portion and a guard facing the notch, or by making the shape of the shackle pin and the pin hole non-rotatable. provide. Therefore, it is possible to prevent a problem that the shackle pins rotate together during use.

The slider is an annular body surrounding the shackle main body, and a pin or a block is fixed to a substantially central portion thereof, or a set screw is screwed outside the shackle main body to prevent the shackle main body from coming off. ing. Therefore, both ends of the shackle body can oppose the opening force and do not bend, preventing damage to the shackle pin and allowing the shackle to hang the hanging support horizontally or diagonally. become.

Further, the present invention provides a configuration in which one of the slope holes is formed in a clockwise direction, and the other is formed in a counterclockwise direction in such a manner that the slope is gradually and gradually inclined. Therefore, when the shackle pin is rotated clockwise with the operation handle,
The lock pin goes up the slope of the slope hole and makes a half turn of the head portion, and then goes down the slope of the other slope hole to engage. Further, the slider is characterized in that a concave portion for fitting the edge of the hanging support is formed. Therefore, after connecting the shackle-shaped hanging tool to the hanging support with the shackle pin, the slider itself is moved with the shackle body in horizontal or diagonal hanging by moving the slider and fitting the concave portion to the edge of the hanging support. The members cooperate to lift and support the hanging supports.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a first embodiment of the present invention.
8, the shackle-type hanging device 1 includes a U-shaped shackle main body 2, a shackle pin 3 for integrally connecting both ends thereof, and a slider 4. The shackle body 2 is formed by forming a substantially circular enlarged portion 5 at both ends of a steel bar having a rectangular cross section, and forming a U-shaped pin hole 5a, 5a through which the shackle pin 3 is inserted. It is bent. The shackle body 2 is not limited to a steel bar having a rectangular cross section, but may have a circular cross section or another shape.

The slider 4 is a substantially rectangular annular body slidably fitted to the shackle main body 2 (see FIG. 6), and has a retaining block 4c fixed by pins 4b, 4b at a substantially central portion thereof. 4d is a retaining member for the pin 4b. The retaining block 4c and the like are omitted, and the retaining screw 22 is provided outside the shackle body 2 as shown in FIG.
May be screwed into the shackle body 2 to prevent the shackle from coming off.

On the other hand, a shaft 10 having a cam portion 7 at one end is rotatably mounted on the shackle pin 3 by a coil spring 8 so as to be rotatable outward. The cam portion 7 is a shaft having the same diameter as the shackle pin 3 formed at the tip of the shaft 10.
0 is eccentric to the shackle pin 3, is inserted into a shaft hole 11 provided in the longitudinal direction, and is rotatable inside the shackle pin 3. That is, as shown in FIG. 7, the shaft 10 is eccentrically arranged so as to have a parallel axis 30 slightly away from the axis 40 of the shackle pin 3. Therefore, the center line 50 of the cam portion 7 coincides with the axis 40 of the shackle pin 3, and the shackle pin 3 can be inserted and removed. On the other hand, when the shaft 10 is rotated, the cam portion 7 also rotates to reach the cam portion 7 ′, and the center line 50 is also symmetrical with respect to the axis 30 of the shaft 10.
It will change to the position of 0 '. Therefore, a part of the cam portion 7 'protrudes outside from the pin hole 5a, so that the shackle pin 3 cannot be inserted or removed, and the shackle pin 3 can be prevented from being removed.
In each of the drawings, the cam portion 7 'indicates a change in the position of the cam portion 7, and both are the same member. Also, as shown in FIGS. 1 and 3, the guards 21 and 21a are connected to the shackle main body 2 in order to prevent external force from being applied to the cam portion 7.
Are arranged in a fan shape.

A large-diameter shaft hole 9 is provided at an end of the shaft hole 11 on the cam portion 7 side, and a coil spring 8 is inserted therein. Therefore, when the cam portion 7 comes out of the pin hole 5a, it can protrude outward by the force of the coil spring 8. A key groove 6 is formed on the outer peripheral surface of the shackle pin 3, and a key screw 12 screwed from outside the enlarged portion 5 can be engaged with the key groove 6 as shown in FIG. The length of the keyway 6 is substantially the same as the opening distance between both ends of the shackle body 2.

The other end of the shackle pin 3 is integrally formed with a head portion 13 having a diameter larger than that of the shackle pin 3.
An operation handle 14 is provided which is in contact with the head portion 13 and in which the end of the shaft 10 is screwed. A knob 15 is formed integrally with the operation handle 14, and when the knob 15 is rotated, the shaft 10 coupled to the operation handle 14 rotates, and the cam 7 rotates.

A guard 16 is provided outside the operation handle 14.
16a is fixed to the shackle main body 2 so as to surround the head portion 13, the operation handle 14 and the like in the diameter direction. Therefore, the guards 16 and 16a are connected to the head 13,
The purpose is to protect the operation handle 14 and the like from external force being applied. 2, a notch 13a is formed at the upper end of the head 13 so as to face the guard 16, and the notch 13a and the guard 16 prevent the shackle pin 3 from rotating together. be able to. The shape of the shackle pin 3 and the pin hole 5a may be made elliptical or the like so that the shackle pin 3 cannot rotate.

On the other hand, as shown in FIGS. 1, 2 and 5, a lock pin 18 protrudes from the operation handle 14 on the surface where the head 13 and the operation handle 14 are in contact with each other. The head portion 13 is provided with a slope hole 19 with which the slope hole 19 is engaged and a slope hole 20 at a position diametrically opposed to the slope hole 19. Slope hole 1
The slope hole 9 and the slope hole 20 are on the circumference of the same radius, and the slope hole 19 is formed with slopes 19a, 20a which are gradually inclined in the clockwise direction and in the slope hole 20 in the counterclockwise direction. Accordingly, when the operating handle 14 is rotated clockwise by 180 degrees, the lock pin 18 comes out of the slope hole 19 and rotates, and the slope 2 of the slope hole 20 is rotated.
After moving from 0a to the end, the head 13 and the operation handle 14 are brought into contact again.

The operation of the first embodiment will now be described. The cam portion 7 shown by a solid line in FIG. 1 is in a state where the center line 50 of the cam portion 7 and the axis 40 of the shackle pin 3 coincide with each other as shown in an enlarged manner in FIG. 3 shows a state in which the shackle pin 3 can be inserted and removed. On the other hand, the cam portion 7 'shown by a two-dot chain line has its center line 50' separated from the axis of the shackle pin 3, and a part of the cam portion 7 protrudes outward, so that the shackle pin 3 can be inserted and removed from the pin hole 5a. Indicates an impossible state. Similarly, the lock pin 18 indicates the position where the lock pin 18 illustrated by a broken line is the former, and the lock pin 18 ′ illustrated by the two-dot chain line indicates the position where the latter. Therefore, the lock pin 18 'indicates a change in the position of the lock pin 18, and both are the same member.

In FIG. 1, the shackle body 3 and the shackle pin 3 are connected to each other by the cam portion 7 'shown by a two-dot chain line extending outward, that is, the shackle pin 3 in a state in which the shackle pin 3 cannot be inserted and removed can be inserted and removed. (The cam part 7 'in the state of the two-dot chain line)
1 and FIG.
, The knob 15 is rotated approximately 180 degrees counterclockwise. Then, the knob portion 15 has the notch portion 13
a and the guard 16 facing the notch 13a prevent co-rotation, so that only the operation handle 14 rotates. That is, when the head portion 13 tries to rotate together with the knob portion 15, the notch portion 13a abuts on the guard 16, so that the rotation of the head portion 13 is restricted. As a result, only the knob 15 rotates about 180 degrees, and FIG.
The lock pin 18 ′ located in the state shown by the dashed line rotates out of the slope 20 a of the slope hole 20 and rotates in the slope hole 1.
9 and slides to the slope 19a, and reaches the position of the lock pin 18 shown by a solid line in FIG. As a result, the center line 50 of the cam portion 7 formed at the tip of the shaft 10 coincides with the axial center line 40 of the shackle pin 3 and fits into the rod, forming an integral rod-like body, and protruding from the shackle pin 3 by the force of the coil spring 8. Then, the relative surface of the operation handle 14 and the head portion 13 comes into contact with each other. In this state, the shackle pin 3 can be inserted and removed, and can be easily pulled out from the pin hole 5a of the shackle body.

Therefore, when the center line 50 of the cam portion 7 and the axis 40 of the shackle pin 3 coincide with each other, as shown in FIGS. Since it has the same diameter, the shackle pin 3 can be pulled out by pulling the knob portion 15 to the head portion 13 side, and the shackle body 2 can be removed from the suspended load or the wire of the suspended load, or the shackle body can be attached. Can be. When the shackle pin 3 is continuously pulled out to the head portion 13 side, as shown in FIG.
The shackle pin 3 is not completely removed from the shackle main body and does not come off because the shackle pin 3 is stopped by contacting the end face of the cam portion 7.

Next, the shackle pin 3 is connected to the shackle body 2.
When the shackle pin 3 is pulled out, the shackle pin 3 is pushed into the pin hole 5a on the side from which the cam portion 7 has been removed (the position of the cam portion 7 shown by a solid line in FIGS. 1 and 7).
When the knob portion 15 is rotated clockwise by about 180 degrees, the center line 50 of the cam portion 7 rotates clockwise through the shaft 10, thereby separating from the axis 40 of the shackle pin 3. The center line 50 is also changed to the position of the center line 50 ′, which is a symmetrical position with respect to the axis 30 of the shaft 10, and a part thereof protrudes outward from the pin hole 5 a and comes out. Stop. That is, a state in which the shackle body 2 and the shackle pin 3 are joined by the cam portion 7 'shown by a two-dot chain line projecting outward from the position of the cam portion 7 shown by the solid line in FIGS. It becomes a state.

The lock pin 18 comes out of the slope hole 19 and engages with the slope hole 20. Therefore, rotation of the cam 7 around the shaft 10 in the clockwise direction is prevented, so that a state in which a part of the cam 7 protrudes from the pin hole 5a to prevent the cam 7 from falling off is maintained, and the shackle pin 3 There is no danger of detachment from the main body 2. Inadvertent rotation of the cam portion 7 is prevented by the guards 21 and 21a, and inadvertent rotation of the knob portion 15 is prevented by the guards 16 and 16a.

In this state, the slider 4 is slid to the vicinity of the guard 16 to prevent the shackle main body 2 from opening, and the shackle-like hanging tool 1 is connected to a wire rope suspended from a crane as shown in FIG. Suspended by another shackle 28 or a hook. Therefore, the shackle-shaped hanging tool 1 enables safe horizontal or oblique hanging of the hanging support 23.

Next, the second embodiment shown in FIGS. 9 and 10 will be described.
A recess 4 a is formed in the shackle body 2 instead of the retaining block of the slider 4.
Is exactly the same as the previous example, except that it is screwed in to prevent it from falling off. Therefore, the same components as those in the previous example are denoted by the same reference numerals, and redundant description will be omitted. By fitting the concave portion 4a of the slider 4 into the hole 24 on the periphery of the hanging support 23 and hanging the shackle-shaped hanging tool 1, as shown in FIG. When suspended, the slider 4 cooperates with the shackle body 2 to suspend
There is a fail-safe action to support the third.

Further, a third embodiment shown in FIGS. 11 to 14 will be described. In this example, the shackle body 2 in the previous example is slightly longer, and a general shackle pin 3a is used instead of the shackle pin 3. This is the same configuration as the previous example except that a screw portion 3b is formed at one end of a shackle pin 3a having a knob portion 15a and a screw groove is formed in a pin hole 5b. Therefore, the same components as those in the previous example are denoted by the same reference numerals, and redundant description will be omitted.

The operation of the third embodiment will be described.
The operation in this example is different from the previous example, in which the shackle pin 3a is inserted from the one pin hole 5a on the guard 16, 16a side into the other pin hole 5b, and the shackle pin 3a is rotated about the axis so that the screw portion 3b is pinned. The shackle engages with a thread groove formed in the hole 5b, and is almost the same as a normal shackle. However, since the normal shackle does not have the slider 4, there is no function of preventing the shackle body 2 from opening in the U-shape. It is needless to say that the recess 4a may be formed in the slider 4 in this example as in the previous example.

[0032]

According to the present invention described above, since the slider is movably fitted to the shackle main body, even if the shackle main body is hung and supported in a manner of causing bending, that is, the hanging load is in the vertical direction. The shackle body and the shackle pin may be damaged without the slider preventing the U-shaped shackle body from opening even if a hanging load is applied in all directions such as the horizontal direction. Does not occur. Therefore, it is also possible to horizontally suspend or obliquely suspend the hanging support using the shackle-shaped suspending tool, which cannot be conventionally performed.

Further, since the concave portion for fitting a part of the hanging support to the slider is formed, the slider is moved together with the shackle body by fitting the part of the hanging support to the concave portion when the slider is moved. A fail-safe function can be achieved as a member for supporting the hanging support.

Further, since the shackle pin can be easily inserted and removed only by rotating the cam portion of the shackle pin with the operation handle, one-touch operation becomes possible. When the shackle-like hanging device is frequently attached and detached, work efficiency is promoted.
When the operation handle is turned after the shackle pin is inserted into the pin hole of the main body, the cam portion protrudes outside the pin hole and forms a stopper for the shackle pin. The danger of falling off is eliminated and safety is ensured.

Further, since the shackle pin is provided with a key groove having a predetermined length and a closed end, and a key screw is screwed into one of the enlarged portions, even if the shackle pin is removed from the other pin hole, the shackle pin can be removed. Prevents one pin hole from falling off.

Further, one of the slope holes is clockwise,
The other formed a slope that gradually slopes in the counterclockwise direction, so that when the shackle pin was rotated clockwise with the operation handle, the lock pin went up the slope of the slope hole and turned the head part half a turn. The shackle pin can be engaged and disengaged by rotating the cam part only by turning the operation handle a half turn in the forward / reverse direction because the shackle pin can be engaged and disengaged by entering the slope hole and descending the slope. .
