Abstract

PROBLEM TO BE SOLVED: To provide an LPG cylinder attachment/detachment device which can be used in changing and loading a cylinder by hooking a simple step in two holes in the right-to-left direction of a lower side of a vent hole in an attachable/detachable manner. SOLUTION: In an LPG cylinder attachment/detachment facilitating device, a simple step 1 having a light hooking part manufactured of pipes with the length L of the hooking part smaller than the height H of an opening of a vent hole 5 in a counterweight 4, is hooked in two hooking holes 6 in the right- to-left direction in a lower side of the vent hole 5 in an attachable/detachable manner and used in changing and loading a cylinder.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an industrial vehicle LPG.
This is related to the attachment / detachment of cylinders for specification vehicles.

[0002]

2. Description of the Related Art In the prior art, an LPG cylinder is mounted as a fuel tank above a counterweight, and when the LPG of fuel is exhausted, the LPG cylinder is replaced by an operator or a worker to replace the cylinder. The expensive large models used to bring pallets and other work benches. As a more specific example of the solution, there is Japanese Utility Model Laid-Open No. 2-126930 having a dedicated mounting device.

[0003]

Therefore, in the case of a large and tall model, the work of loading the cylinder on the upper part of the counterweight involves dangerous heavy labor. In the new model, the cylinder is stored inside as a special counterweight. (See Japanese Unexamined Utility Model Publication No. 2-33727), and Japanese Unexamined Utility Model Application Publication No. 2-1269 having a dedicated mounting device.
Although there is also one disclosed in Japanese Patent Publication No. 30, it becomes expensive, and it is difficult to deal with a conventional general standard car on the spot or to change specifications of a used car. In particular, it is unavoidable to load the LPG cylinder of the fuel tank on the upper part of the tall counterweight, and there is a problem that the work safety must be considered.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has a hook portion in which the length of the hook portion is shorter than the opening height of the ventilation hole of the counterweight. LPG cylinder made of a simple step having a part made of pipe material to make it lightweight, hooked and detachably attached to two holes drilled on the lower left and right of the ventilation hole, and can be used at the time of cylinder replacement loading It is a device for facilitating desorption.

[0005] By using a dedicated device comprising the above simple steps and a catch hole provided in the ventilation hole of the counterweight as a device for facilitating attachment / detachment of an LPG cylinder, an operator or a worker can easily carry out a cylinder replacement loading operation. In addition to being able to do so, it is possible to deal with ensuring safe work at a low cost.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described.
This will be described with reference to the drawings. 1 is a partial cross-sectional view of the rear side of the counterweight, FIG. 2 is an explanatory view of the shape of a simple step, and FIG. 3 is a rear perspective view of an industrial vehicle.

As shown in FIG. 1, LP is generally used as a fuel.
For industrial vehicles using G, LP as a fuel tank
The G cylinder 3 is attached to the upper rear of the counterweight 4. When the fuel in the LPG tank is exhausted, the operator or the operator removes the empty LPG cylinder 3 and transports and brings a new LPG cylinder 3 filled with fuel to carry out replacement loading work. become. When the filled LPG tank 3 is large, it weighs from 30 kg to 40 kg.

When the size of an industrial vehicle becomes large, the upper part of the counterweight 4 exceeds 1 m.
The replacement loading operation of the G cylinder 3 is dangerous heavy labor, and as a solution to this, a technique for lowering the loading position of the fuel tank and a method including a dedicated loading device are disclosed.

[0009] However, it is difficult to respond to the conventional general standard car on-site and to change the used car by changing specifications, etc., so that the LPG cylinder 3 of the fuel tank is placed above the tall counterweight 4. The loading work has not gone away.
An object of the present invention is to provide a simple step 1 as shown in FIG. 2 in consideration of securing a scaffold so that such an unavoidable loading operation can be performed easily at the lowest possible cost. It is to be.

In FIG. 1, the simple step 1 is performed by setting the opening height H of the ventilation hole 5 of the counterweight 4
It is a lightweight one manufactured using a pipe material with a shorter hook length L, and can be easily carried by an operator. Simple step 1 consists of two hook holes 6 on the left and right
It is designed to be attached and detached by hooking on a cylinder and used when loading cylinders.

Further, according to the size of the model of the industrial vehicle,
After the installation of the simple step 1, the dimensions from the ground are prepared so as to be optimal for an operator to load the LPG cylinder 3 on the upper part of the counterweight 4, and are prepared for exclusive use of the model. Things.

Therefore, by using the LPG cylinder detachment facilitating device, the operator transports the heavy LPG cylinder 3 to the rear part of the counterweight 4 and then lifts it, puts his feet on the steps and pushes up. Therefore, the LPG cylinder 3 can be safely stored in the loading position with the same work setup.
