Description

[Detailed explanation of the invention] This invention relates to a transport vehicle that can be used as a track to move around existing concrete waterways with a U-shaped cross section installed in irrigation canals and other areas, and is used when constructing new or extending concrete waterways. It is used for small-scale transportation such as concrete waterways such as concrete U-shaped ditches, other construction materials, machinery tools, and other materials.

Most of the construction of side ditches, agricultural waterways, etc. is now made of secondary concrete products with a U-shaped cross section.

The construction of this concrete waterway can be carried out using mechanical power such as a small crane truck if the construction site is large and the scaffolding is in good condition. Where possible, concrete waterways will be carried and laid to locations that can be accessed by small trucks, trailers, etc.

If the site conditions become even worse and it is impossible for even a small truck or even a trailer to enter the site, the reality is that four people will have no choice but to transport people through a single concrete channel.

This transportation of human skin is not only disadvantageous in terms of efficiency, but also makes the work itself harsh and dangerous, and ultimately makes it impossible to complete the normal construction schedule. The development and practical application of transportation methods was long-awaited.

This invention was developed and researched to solve these problems, and the details of its structure are as detailed below.

That is, as can be understood from the plan view based on the typical embodiment of this invention shown in FIG. The axle 2, which serves as a support, is mounted.

Front wheels 3.3 are fixed to both ends of this axle 2 so that their separation distance can be adjusted freely, and the front wheels 3.3 are attached to the rising walls DI on both sides of the existing U-shaped concrete waterway.

The front wheels 3, 3 are positioned approximately on the respective central axes of Dl.

On the other hand, horizontal wheels 4, 4 for preventing derailment are formed to form a pair with the front wheels 3, 3.

As shown in the side view of FIG. 2, the horizontal wheels 4, 4 for preventing wheel derailment are located directly below the front wheels 3, 3, and
As shown in the sectional view taken along line a-a' in FIG. 1, shown in FIG.
The outer portions of the horizontal wheels 4, 4 are regulated so as to be inscribed in the rising walls DI, DI of the existing U-shaped concrete waterway.

Further, each of the horizontal wheels 4, 4 is supported via a spring 5.5, and each of the horizontal wheels 4, 4 is individually formed so that its horizontal position can be adjusted, so that the front wheels 3, 3
It can be adapted to existing U-shaped concrete channels of various sizes with different groove widths, and
Rising wall DI, DI of existing U-shaped concrete channel
It can adapt well to the unevenness of the inner wall surface and the level difference during construction, and can prevent lateral wobbling during the use of the transport vehicle.

At the rear of the vehicle body 1, as clearly shown in the side view shown in FIG. 2, a vertical shaft 7 having a rear wheel 8 at its tip is pivotally supported. If the vertical shaft 7 is made to project upwardly from the vehicle body 1 and the bundle 6 is attached to the end thereof, it will be advantageous for the operation of the vehicle.

Naturally, this vertical shaft 7 is designed so that the rear wheel 8 formed at its tip always comes into contact with the inner bottom D2 of various existing U-shaped concrete waterways of different sizes. In addition, it would be extremely advantageous if the shaft support to the vehicle body 1 was of a sliding type whose length can be changed.

The wheels used for this transport vehicle, including the front wheels 3, 3, horizontal wheels 4, 4, and rear wheels 8, must be made of rubber or other materials with sufficient strength. ,
In addition, the horizontal wheels 4, 4 are relatively small in size.
A diameter of approximately 10 cm is sufficient, but for the front wheels 3, 3 and rear wheels 8, appropriate sizes of approximately 10 to 15 cm must be selected from the viewpoint of operability and durability.

As mentioned above, the transport vehicle of this invention is used for transporting places where only entry-side transport can be relied upon, and where a U-shaped concrete channel has already been laid or is being constructed. By laying the pieces one by one and using the U-shaped concrete channel, they form an ideal track and enable safe and quick transportation.Moreover, the front wheels are The horizontal wheels forming the U-shaped concrete channel are combined to ensure that the upper surface of the rising wall of the U-shaped concrete channel is captured, and the rear wheels are designed to follow the bottom surface of the U-shaped concrete channel, so the resistance is extremely low. It has a simple structure that is easy to operate not only on straight sections but also on curves.

Furthermore, since the structure can be adapted to existing U-shaped concrete waterways of various sizes, it is possible to achieve efficient transportation at an overall low cost.

Therefore, the transport vehicle can be extremely useful not only in construction work for U-shaped concrete waterways, but also as other transportation means.
