Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support device for transportation used when transporting pipes such as gas supply pipes, sewer pipes and water pipes by a truck such as a truck. The present invention relates to a supporting device for carrying, which supports a pipe so as to be movable in a longitudinal direction at least during the work, in order to easily carry out a work of transferring the pipe to another machine or a work of unloading the work after carrying.

[0002]

2. Description of the Related Art In recent years, maintenance of water supply and sewer pipes, gas supply pipes, etc. has been actively carried out with the urbanization. The burial work for these pipes involves excavating the ground surface into a groove, and then extending it by sequentially connecting pipes or culverts made of steel pipe, concrete, cast iron or the like.

Usually, most of these pipes such as water supply and sewer pipes and gas supply pipes are buried under the road, so the work is carried out while restricting traffic such as closing one lane. As the pipe body used for the sewer pipe or the like, steel pipes, pipes made of concrete or the like are used as described above,
Even in blocks, it will be quite heavy. In the case of large-medium diameter pipes, apart from small-diameter pipes, it cannot be handled by human power at all, and they are installed by heavy equipment such as a truck crane placed horizontally.

However, with the increase in traffic volume in recent years, restrictions on road regulations have become strict,
Even when a road occupancy permit is obtained, there is a case where the area occupied is required to be reduced, and there are also significant time restrictions. Therefore, there is a problem that a heavy machine such as a crane cannot be installed beside the excavation groove.

Therefore, the applicant of the present invention has previously filed Japanese Patent Application No. 5-64.
In JP 308, the trucks are stopped in a row and the pipes are transferred in the longitudinal direction without using a heavy machine such as a crane, so that the pipes are installed by occupying only the trench excavation work portion. We have proposed a pipe handling device that can be used.

[0006]

In such a pipe handling device, the pipes are unloaded from the loading platform in a state where the truck carrying the pipes is stopped in parallel with the handling device. For example, the pipe is placed on the sleepers placed on the bed, and the pipe cannot be moved in the longitudinal direction as it is.Therefore, you can bite a roller or the like under the pipe or use a winch or the like. The pipe was moved by pulling it toward the handling device.

However, since the pipe has a circular cross-sectional shape and is easily rolled laterally, the above-mentioned work for laying the roller and the work for moving with the winch are very dangerous work, and the work is very troublesome. It was a hanging thing.

Therefore, the main object of the present invention is to firmly support the pipe so that it will not move during transportation, and
(EN) Provided is a supporting device for transportation, which can safely move pipes mounted on a truck or the like in a longitudinal direction when unloading.

[0009]

The above-mentioned problem is a supporting device for carrying, which is placed on a bed of a carrier for carrying pipes and supports the pipes to be loaded, wherein the carrying device comprises: The problem can be solved by providing a wheel that is in contact with the surface of the cargo bed, at least movable in the longitudinal direction of the pipe at the time of unloading, and provided with a movement preventing means for making it immovable during transportation. As the movement preventing means, a braking means for wheels may be adopted, but in another aspect, the carrying support device is such that wheel holders that respectively hold the wheels are rotatable with respect to four corners of the base. And the opposite wheel holders on the left and right sides are connected to each other by cylinders at the upper ends thereof, and the wheel holders are rotated by the expansion and contraction operation of the cylinders, and the wheels are moved relative to the bed surface. It may be possible to switch between a state in which the wheels are in contact with each other and movable in the longitudinal direction of the pipe, and a state in which the wheels are separated from the surface of the bed and the base is in contact with the surface of the bed to be immovable.

In this case, by providing a winch for assisting the movement of the pipes when unloading the pipes,
It becomes a more suitable device.

[0011]

According to the present invention, the vehicle is provided with the wheel contacting with the surface of the cargo bed so as to be movable at least in the longitudinal direction of the pipe at the time of unloading, and to be in the non-movable state during transportation. Therefore, during transportation of the pipe, the pipe can be firmly held so that it does not move, and at the time of unloading, the pipe can freely move in the longitudinal direction, so that the unloading can be easily performed by transferring in the longitudinal direction from the loaded state. be able to.

Wheel holders for holding the wheels are rotatably provided at the four corners of the base, and the wheel holders facing each other are connected to each other by cylinders at their upper end portions on the left and right sides. In the case of a supporting device, when the cylinder is operated, the wheels do not come into contact with the bed surface during transportation, which results in a sticky state, so that the pipe does not move by any chance and safety during transportation is improved.
