Abstract

PURPOSE:To set an effective width of a ramp for passage to be the entire width of the ramp, by locating a hydraulic cylinder mechanism at a position lower than the ramp. CONSTITUTION:When a rod of the hydraulic cylinder mechanism 10 is stretched, a flap body 9 is rotated leftward with a movably fitting part 8 as a fulcrum, and simultaneously the mechanism 10 is also rotated with a fitting part of a ship's bottom part 5' as a center. When the flap body 9 reaches an upright condition, an opening 11 of a main body 7 of the ramp accords to an opening 12 provided on the side of the flap body 9, and a pin 14 is inserted therein by driving a cylinder rod 15 of a locking mechanism, whereby the main body 7 of the ramp and the flap body 9 are integrated with each other. Thereafter, when the rod of the mechanism 10 is contracted, the flap body 9 is rotated to the original position. Concurrently with this constitution, the main body 7 of the ramp is raised, and is stored in the ship's hull in an uprigh state.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lamp device used in roll-on/roll-off ships, etc., and is particularly characterized in that a wide lamp can be obtained.

The conventional lamp, as shown in Figure 1 (plan view),
The base end 02' of the lamp body 02 is pivotally attached to the lamp body 1, and the lamp body 02 is used by being turned vertically by means of fluid cylinder mechanisms 03.03 provided on both sides thereof. However, this conventional type has the following drawbacks.

(b) If the lamp is wide or divided into two or more parts, a fluid cylinder cannot be installed in the middle of the width or in the divided unit because it will prevent traffic.

(b) Since fluid cylinders are provided on both sides of the lamp, W becomes narrow during active traffic δ Also, as a solution to this problem, a fluid cylinder o4 is provided below the lamp body 02 as shown in FIG. Although a device is considered, it has the following drawback as a new problem.

(a) When the lamp is stored, the rotor 04' of the 5 fluid cylinders o4 is exposed, which is unfavorable in terms of rust prevention, and maintenance is also difficult because it is outside the ship.

(There is a risk that the fluid cylinder 04 will be exposed to waves when the lamp is installed, which will shorten the life of the fluid cylinder 04.)

This invention was made in order to solve the above-mentioned problems of the prior art, and includes a lamp body whose lower proximal end is pivotally connected to the stern and has an opening at a position distant from the pivot part, and a fluid cylinder mechanism, one end of which is pivotally mounted to the ship's hull so that the axis of rotation coincides with the pivot part; an opening that matches the opening of the lamp body is provided at a position spaced apart from the pivot part; and a lower end of the other end is attached to the ship's hull. a flap body pivotally attached to the tip of the lamp body, and a locking mechanism that is attached to the lamp body or the flap body side and that when the opening of the lamp body and the opening of the flap body coincide, a pin is fitted into both openings. ,
The ship lamp device is characterized in that it comprises an auxiliary flap body that connects the top surface of the lamp body and the top surface of the flap body.

This invention will be described with reference to the drawings together with the embodiments. FIG. 3 is a side view showing the overall configuration of the invention.
is the stern part of a roll-on/roll-off ship, etc., 6 is the cargo handling quay, 7 is the stern part 5V, and 7 is the main body of the stern, whose base end is pivoted at the lower end with a pin 8. 9 is one end of which is similarly pivoted with the pin 8. The flag body 9 has a rod tip of a fluid cylinder mechanism 10 rotatably attached to the bottom 5' of the stern 5 pivoted to the lower end of the flag body 9. Furthermore, the pivot point between the base end 7' of the lamp body 7 and the flap body 9 (pin 8
), as shown in FIGS. 4 to 6, an opening 11 is provided at the base end 7' of the lamp body, and an opening 12 is provided at the eye 9' of the flap body 9. When the flap body 9 rotates about the pin 8, the flaps are provided at positions that coincide with each other. Furthermore, 13 is an auxiliary flap that connects the top surface of the lamp body 7 and the top surface of the flap body 9;
Reference numeral 14 designates a pin of a locking mechanism which is inserted and removed when the openings 11 and 12 are aligned with each other by a cylinder rod 15 attached to the proximal end 7' of the lamp body or the eye 9' side of the flap body 9. Note that 16 is a support bracket whose lower end is fixed to the stern part 5, and 17 is a support bracket fixed to the base end 7 of the wrap body 7.
This is a stopper provided on the ' side. A plurality of pins 8 and locking mechanisms are arranged in the width direction of the rung body 7.

The operation of the present invention is such that in order to store the lamp body 7 in the hull during cargo handling as shown by the solid line in FIG. 3, the rod of the fluid cylinder mechanism 10 is first extended, and the flap The body 9 is rotated to the left about the pivot portion 8, and at the same time, the fluid cylinder mechanism 10 is also rotated to the dotted line shown in the figure about the attachment portion of the bottom portion 5'. When the flap body 9 is in an upright state, the opening 11 of the lamp body 7 and the opening 12 on the flap body side coincide with each other, so the cylinder rod 15 of the locking mechanism is driven and the pin 14 is inserted there. By inserting the pin 14, the lamp body 7 and the flap body 9 become one body, and then when the rod of the fluid cylinder mechanism 1o is reduced, the flap body 9
rotates to its original position (to the right in Figure 3). The lamp 7 is then raised and stored in the hull in an upright position. In this case, the support body 17. to secure it to the hull.

Next, when the ramp body 7 is to be erected for cargo handling, the operation is the reverse of the above, that is, by raising the flag body 9 to the left, the ramp body 7 will bridge over the quay 6, and then the pin 14 of the locking mechanism will be opened. When the rod of the fluid cylinder mechanism 1o is pulled out from 11 and 12, only the □ of the flap body 9 rotates to the right and returns to its original position, forming a running surface. The auxiliary bulb 13 is connected to the lamp body 7,
It is provided so as not to create a gap with the flap main body 9, and there are no particular limitations on the mechanism. In the present invention, one end of the plate body is pivotally attached to the flap body 9 in a row.

As described above, this invention has the following effects: (a)
Since the fluid cylinder mechanism for operating the lamp is located below the lamp, it can be divided in the width direction of the lamp, and the entire width of the lamp can be maintained when the lamp is active for traffic.

(b) Since the rod of the fluid cylinder mechanism is in a contracted state when the lamp is stored, maintenance work can be saved, and the fluid cylinder mechanism will not be damaged by waves when the lamp is installed.

(c) By increasing the length of the flap body, the thrust of the fluid cylinder can be reduced.
