Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a loading platform structure for a transport vehicle in which a portion of the loading platform is provided in the spaces on both sides of a traveling device installed below the loading platform. , Heavy loads such as earth and sand can be transported stably with a low center of gravity, while lightweight and wide loads with support stands located at both ends of the loading platform can be transported stably with a wide loading platform. It is something to do.

(B) Prior art In the past, some vehicles equipped with a running device were equipped with running resistance elements in the space on both sides of the running device in order to effectively utilize the space.
Publication No. 11353). However, among transport vehicles having a loading platform above the traveling device, there has not been one in which a part of the loading platform is provided in the spaces on both sides of the traveling device to make effective use of the loading platform.

(c) Problems that the invention aims to solve By the way, in this type of transport vehicle, the top surface of the bottom plate of the loading platform (loading platform surface) is flat, so the loading platform is raised and the center of gravity is raised.
Therefore, as a solution to this problem, it is possible to lower the center of gravity by lowering the entire bottom plate of the loading platform while leaving the traveling gear part, but the traveling gear part of the loading platform bottom plate will protrude from the loading surface as a cover. This may cause problems such as difficulty in loading some cargoes.

(d) Means for Solving the Problems Therefore, the present invention provides a transport vehicle in which a loading platform 2 having a flat loading platform bottom plate 2a is disposed above the traveling device 1, in which spaces S on both sides of the traveling device 1 are provided. ,
A recess 7 integral with the load platform 2 is formed downward from both sides of the load platform bottom plate 2a, and the recess 7
A side pocket 8 is formed on the lower surface of the side pocket 8, and the loading platform flat forming surface 8b of the side pocket 8 is placed in a U-shaped facing position at the bottom of the loading platform, and the loading platform flat forming surface 8b and loading platform surface F are flush with each other. The side pocket 8 is configured to be removably fit into the recess 7 by changing its position so that it faces down in an inverted U shape.

(c) Effect With the above configuration, if necessary,
The side pocket 8 has a U-shaped face-up position where the loading platform flat forming surface 8b is at the bottom of the loading platform, and an inverted U-shaped facing position where the loading platform flat forming surface 8b and the loading platform surface F are flush with each other. In the former case, heavy soil, etc. can be loaded onto the loading surface F and the side pocket 8, and it can be transported stably at a low center of gravity; If the load is lightweight and wide, and the load support stands are located on both sides, and it would be a problem if the center of the load touches the platform bottom plate 2a, the platform surface F and the platform flat forming surface 8b should be placed at the same level. It can be formed on one wide flat surface and used in a variety of ways.

(F) Example Hereinafter, a case where the present invention is applied to a small transport vehicle will be explained with reference to the drawings.

First, in this small-sized transport vehicle, a loading platform 2 is connected to the upper part of a traveling device 1 by a chassis frame 3, and at the rear of the loading platform 2 is an engine 4 and a drive case 5 that appropriately reduces the speed of the power and transmits it to the traveling device 1. , handle 6, etc. are arranged and configured.

By the way, in this loading platform structure, recesses 7 that protrude toward the space S on both sides of the traveling device 1 are formed on both sides of the flat loading platform bottom plate 2a, and the side pockets 8 are fitted into each recess 7 with the front and back reversed. It is configured to be removably fitted.

The recesses 7 are formed in the front-rear direction on both sides of the platform bottom plate 2a, and a fitting hole 7a for the side pocket 8 is formed in the bottom wall of the recess 7, and a holder 7b is formed around the fitting hole 7a.

The side pocket 8 can be used by changing its position between facing up and down.When facing up, the side pocket 8 has a U-shaped shape with a collar-shaped fitting part 8a formed around the upper end. The opening is box-shaped.

The side pocket 8 is used by inserting it into the insertion hole 7b of the recess 7 with the U-shaped face facing up.
The fitting part 8a is held by the holding part 7b, and the loading platform bottom plate 2
U-shaped U-shaped surface that can be held below the loading platform surface F on the top surface (in the embodiment, it can be stored in the recess 7 and side pocket 8);
Once removed and turned over in an inverted U shape so that the loading platform flat forming surface 8b is the top surface, fit into the recess 7, fit into the fitting part 8a, and connect the fitting part 8a to the holding part 7.
b and hold it against the loading platform flat forming surface 8.
b and the loading surface F are flush (in the structure of the embodiment, the depth of the recess 7 and the height of the side pocket 8 are formed to be the same, so that they are flush) in an inverted U-shaped face-down position ( The inverted U-shape shown in FIG.

Although not shown, the fitting hole 7 and the fitting part 8
If a is not provided, U of side pocket 8
When the side pocket 8 is in the face-up position, the side pocket 8 is in the concave part 7.
As a result, the amount of storage is reduced by the amount accommodated in the recess 7 compared to the case where there is the insertion hole 7a and the fitting portion 8a.

(g) Effect of the invention As described above, the present invention has the advantage that the space S on both sides of the traveling device 1
, downward from both sides of the platform bottom plate 2a,
A recessed portion 7 is formed integrally with the loading platform 2, and a side pocket 8 is formed on the lower surface of the recessed portion 7, so that the loading platform flat forming surface 8b of the side pocket 8 is at the bottom of the loading platform in a U-shaped facing position; The position of the side pocket 8 is changed so that the loading platform flat forming surface 8b and the loading platform surface F are flush with each other in an inverted U-shape, and the side pocket 8 is configured to be able to be removably fitted into the recess 7. When loading a load that can be stored in the side pocket 8, the load is placed in a U-shaped face-up position and is also loaded below the loading surface F, lowering the center of gravity and improving running stability. In addition, when a wide flat surface is required for a large load, it is convenient to use the upside-down U-shaped orientation.
