Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a new concrete pump truck.

[Conventional technology]

As shown in FIG. 3, the conventional concrete pump vehicle has a driver's cab 2 on the front end of the chassis 1, a concrete receiving hopper 3 and a pressure feeding device 4 on the rear end of the chassis 1, and A swivel base 5 is provided at a position close to the rear of the driver's cab 2 on the top, and a plurality of booms 6a,
6b and 6c are foldably connected to constitute a boom mechanism 6, and a concrete pipe 7 connected to the rear pumping device 4 is guided to the front swivel table 5, and is arranged along the booms 6a, 6b, and 6c. In this way, concrete is poured from the tip of the boom mechanism 6.

[Problems to be solved by the invention] However, in the conventional concrete pump vehicle mentioned above, since the swivel base 5 is provided at the front position of the vehicle body, the distance from the pumping device 4 to the swivel base 5 is large. Therefore, there was a problem in that a long concrete pipe 7 was required. That is, since the concrete pipe 7 is subject to severe wear and is a consumable item, it is more economical to make it shorter.

The present invention was developed in view of the above-mentioned conventional problems, and aims to shorten the length of concrete piping by locating the swivel base that supports the boom mechanism at the rear of the vehicle body.

[Means for solving problems]

The present invention is an attempt to solve the above-mentioned technical problem. A swivel base supporting a boom mechanism is provided at the rear of the vehicle body, and a concrete pipe provided along the boom mechanism is routed through the swivel base to the rear of the vehicle body. This invention relates to a concrete pump vehicle, characterized in that the concrete pump vehicle is connected to a pumping device provided at be.

[Effect]

Therefore, in the present invention, concrete can be placed using a boom mechanism supported on a swivel table provided at the rear of the vehicle body and concrete piping.
Furthermore, the distance between the swivel table and the pumping device is shortened, so that the concrete piping is shortened.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

Figures 1 and 2 show an example of the present invention, in which a swivel base 5 that supports the boom mechanism 6 is installed near the upper part of the shaft of the rear wheel 8 of the chassis 1, and the boom mechanism 6 is foldable forward. The operator's cab 2 is provided on the front side of the chassis 1 so that the operator's cab 2 does not interfere with the boom mechanism 6 when it is folded and stored. In the figure, parts with the same reference numerals as in FIG. 3 indicate the same parts.

As mentioned above, since the swivel base 5 is located at the rear of the vehicle body, the swivel base 5 and the pumping device 4 can be brought very close together, and the concrete pipe 7 can be shortened accordingly. I can do it.

Furthermore, by installing the driver's cab 2 on the side of the vehicle body, the boom mechanism 6 can be extended to the side of the driver's cab 2 when the boom mechanism 6 is folded and stored, making the length of the boom the same as the conventional length. Or it can be made longer than before.

Note that the present invention is not limited to the above-mentioned embodiments, and the folding method of the boom mechanism, the model of the vehicle body, etc. may be changed in various ways, and various other changes may be made within the scope of the gist of the present invention. Of course.

[Effect of idea]

As described above, according to the concrete pump vehicle of the present invention, by providing the swivel base that supports the boom at the rear of the vehicle body, the swivel base and the pumping device can be brought close together, and thus the concrete pumping vehicle, which is a consumable item, can be An excellent effect can be achieved in that piping can be shortened and equipment and running costs can be reduced.
