Abstract

PURPOSE:To facilitate mounting and removal work of a cylinder, by constituting a holding means, which holds a bracket supporting the fuel cylinder for a car body to a set position, in such a manner that the holding means can be held to a non-set position when said means is operated to said position. CONSTITUTION:In a liquefied petroleum gas (LPG) folklift or the like, an LPG cylinder G mounted to the rear part of a car body is supported by a supporter contained with a cylinder supporting bracket 4 supported by a pivot 3 to a base 2 fixed to a side of the car body. This bracket 4 is held to a set position by engaging a stopper pin 5 through a spring 6 to a stopper hole 8 in a stopper member 7 secured to said bracket 4. Here a flange 10 is fixed to an operational side end of the pin 5 while a stopper 20 is fixed to a side of the base 2 on a bracket 24, when the pin 5 is extracted from the hole 8 to turnably hold the bracket 4, said pin 5 can be held to the extracted position by engagement of the flange 10 and the stopper 20.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fuel cylinder support device for an industrial vehicle, and in particular to a fuel cylinder support for an industrial vehicle that allows the attachment and detachment of the relatively heavy fuel cylinder to be carried out safely and easily. Regarding equipment.

Conventionally, as a fuel cylinder support device for an industrial vehicle that uses LPG gas or the like as fuel, a device as shown in FIG. 2 is known, taking the 7 Oaklift as an example.

This support device is located in the vehicle body department.
A substantially hat-shaped bracket 1 fixed to the bracket 1 via a bolt nut N, a base 2 fixed to the bracket 1 via a bolt nut N, and a pair of cylinder support brackets pivotally supported to the base 2 via a shaft pin 3. 4.4, and a locking bin 5 pivotally supported on the base 2 so as to be movable forward and backward in the axial direction;
This locking pin 5 is composed of a spring 6 that urges the locking pin 5 in a direction that constantly inhibits rotation of the cylinder support bracket 4.4. The cylinder support brackets 4, 4 are pulled out from the locking hole 8 of the locking member T, which is constructed by welding or the like between the tip of the locking pin 50 and the cylinder support bracket 4.
Set the rotation permitting MK upper set, the locking hole 8 and the locking pin 5
When the cylinder support bracket 4 is in the engaged state, the cylinder support bracket 4
, 4 were configured to be set in a rotation inhibited state.

However, in such a conventional support device, there are 1, 3 and 3.
As shown in the figure, first, the operator uses one hand R to lock the locking bottle 5.
by pulling it against the biasing force of the spring 6 to release the engagement between the tip of the locking pin 5 and the locking hole 8, and while holding this state with the one hand R, turn the other hand. Place the hand on the body of the cylinder G, pull the cylinder G toward you, rotate the cylinder support bracket 4.4 in the direction shown by the imaginary line in Figure 3, rotate it by the required angle, and then remove the cylinder G. Since it has to be removed from the support device, the locking bottle 5 must be operated with one hand R, and the cylinder G'' must be supported with the other hand. The problem was that it was dangerous to operate with one hand because it was heavy.

The present invention has been devised in view of the current situation, and its purpose is to provide a fuel cylinder support device for an industrial vehicle that can safely and quickly attach and detach a relatively heavy fuel cylinder. This is what we are trying to provide.

In order to achieve this object, the present invention provides a fuel cylinder support device for an industrial vehicle that includes a base fixed to the vehicle body, a cylinder support bracket pivotally supported on the base, and a cylinder support platen F. inhibit or allow rotation;
A collar is fixed to the operation side end of the locking pin, and a locking pin 1 is provided with a locking pin 1 which is biased by a spring so as to prevent rotation in a normal state, and a locking pin is provided on the base side.

The cylinder support bracket is configured to include a stopper that engages with the collar only by a rotation operation after the cylinder is set in the permissible state, and holds the cylinder support bracket in the permissible state.

Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings.

As shown in FIG. 4, the fuel cylinder support device according to this embodiment includes a base 2, a pair of cylinder support brackets 4,
4. ! : It is composed of a locking pin 5, a collar 10 fixed to the operation side end of the locking pin 5, and a stopper provided on the bracket B on the base side.

The base 2Fi is fixed to a bracket 1 formed in a substantially cross-shaped shape through a bolt H-by-nut N, and this bracket 1 is fixed to the rear part of the vehicle body via a bolt B and a nut N.

A pair of vertical walls 21 are erected on the upper surface of the base 2. Holes η are formed in the upper portions of the vertical walls 21, respectively, and the shaft pins 3 are inserted therethrough.

Moreover, on the upper surface of this base 2, there is a platen (approximately U-shaped)
is fixed in the hole 25K #i opened in the vertical wall 24 of this bracket n, into which the locking pin 5 is inserted so as to be movable forward and backward, and in the vertical hole 111 on one side of the platen 23.
24Kti, a stopper is provided protrudingly.

Cylinder support bracket 4.4Fi, approximately crescent-shaped plate) 40.40, and this plate 40, 40
receiving portions 41, 41 fixed to the curved upper surface of the cylinder and curved to have approximately the same curvature as the curvature of the body of the cylinder;
It consists of a locking member 7 installed by welding or the like between the plates 40 and 40 above, and a locking hole 8 opened in this locking member 7. The base 20 is rotatably connected to the vertical wall 21 through the hole 42 opened in the chrysanthemum 40, and the shaft pin 3 inserted into the 42.
It is supported by. In addition, 43 in Fig. 4 is the receiving part 41°4.
10 shows the bread-do insertion holes opened at both ends, 44 shows the plate chrysanthemum, and the reinforcing member installed between 40, respectively.

The locking bottle 5 is formed into a hook shape at its operation side end for easy operation, and the base between the hook portions is shaped like a disk KFi, and has a collar 10 with a notch 11 formed in a part. In addition to being fixed, the locking pin 5 is normally biased in the locking direction by a spring 6 wound around the locking pin 5.

When the tip of the locking bottle 5 is engaged with the locking hole 8, the cylinder support bracket 4.4 is set in a rotation inhibited state, and the locking condition III is released. At times, the cylinder support brackets 4, 4 are set in a rotatable state. That is, the locking bottle 5 and the locking hole 8
To release the engagement state, first pull the locking pin 5 toward you against the biasing force of the spring 6, and the tip of the locking pin 5 retreats through the locking hole 8 and is secured. The condition is canceled.

At this time, the tsuba 10 has a notch 1, as shown by the imaginary line in FIG.
The presence of the pin 1 prevents it from colliding with the stopper, so the pulling operation of the locking pin 5 is not hindered.

From this state, when the locking pin 5 is rotated as shown by the solid line in FIG. , holding the cylinder support bracket 4.4 in a rotatable state.

In addition, in the above embodiment, the stopper 20 is a bracket)
Although it is arranged on the standing wall 24 on the near side of 23, it may be arranged directly on the base 2 or the bracket 1.

Since this invention includes the above configuration, when attaching or removing a fuel cylinder, the locking bin can be set in the cylinder support bracket rotation permissible state by simply operating the locking bin with one hand and rotating it. Thereafter, the one hand can be removed from the locking bottle and the fuel tank can be attached and detached using both hands, so that the attachment and detachment work is safe and easy.
