Description

The present invention relates to a vehicle equipped with a tool for rebuilding a utility pole main hole.

When rebuilding an existing utility pole, if the land for building a new utility pole cannot be secured, a new utility pole is built at the position of the existing utility pole. Conventionally, as a method of constructing a new utility pole at the position of such an existing utility pole, a support arm is horizontally attached to an existing utility pole at the other end, an overhead wire is removed from the existing utility pole and transferred to the support arm, and then the existing utility pole is used. Build a temporary pole body on the support pole, place a support weight on the support stand, fix one end of the support arm to the temporary pole body, remove the other end of the support arm from the existing utility pole, and then install the existing utility pole. Remove the utility pole and build a new utility pole in the same place, then remove the overhead wire from the support arm and move it to the new utility pole, and then remove the support arm, support weight, temporary pole body and support base. A replacement method has been proposed (see, for example, Patent Document 1).

Japanese Patent No. 5527864

According to the utility pole base hole rebuilding method described in Patent Document 1, a new utility pole can be built at the same position as the utility pole to be removed even in a relatively narrow place where a large heavy machine cannot enter, which is required for rebuilding at the utility pole base hole. Working time can be shortened. However, in the utility pole original hole rebuilding method described in Patent Document 1, it is necessary to place a support weight on the support base of the utility pole body in order to support the utility pole body built side by side with the existing utility pole or the new utility pole. Therefore, there is a problem that a work vehicle is required for transporting the support weight, loading it on the support stand, removing it from the support stand, and the like, and it takes time for the work.

The present invention has been made by paying attention to such a problem, and can reduce the number of work vehicles required for the utility pole rebuilding work and shorten the work time required for the utility pole rebuilding work. The purpose is to provide vehicles equipped with rebuilding tools.

In order to achieve the above object, the utility pole original hole rebuilding tool-equipped vehicle according to the present invention temporarily supports the overhead wire removed from the existing utility pole when the existing utility pole is removed and a new utility pole is constructed.

Is fixed to the loading platform, the base member has a supporting portion of the temporary pole, and the supporting portion is provided so as to be able to be positioned on the outside or inside of the loading platform with respect to the gantry frame. And.

When the temporary pole is supported by the utility pole original hole rebuilding tool-equipped vehicle according to the present invention, if the utility pole is moved to the utility pole rebuilding place, the support portion of the base member is positioned outside the loading platform. Temporary poles will be attached to the support and utility poles will be rebuilt. In this way, since the vehicle body becomes a weight, the number of work vehicles required for transporting, loading, and removing the weight for supporting the temporary pillar can be reduced, and the working time can be shortened. Further, since the temporary column is supported by using the base member, it is not necessary to make a hole for the foundation of the temporary column in the ground, and the temporary column main body can be easily and quickly constructed. Further, by positioning the support portion on the outside of the loading platform, the temporary pillar can be supported, and the vehicle body becomes a weight to improve the fall resistance.

In a vehicle equipped with a tool for rebuilding a utility pole base hole according to the present invention, the base member is slidably provided on the gantry frame, and the base leg is provided from a height equal to or higher than the height of the loading platform to below the vehicle installation surface. It is preferable that the base member is provided with a stretchable base jack device.

It is preferable that the arm is attached to the tip of each arm.

In this case, if the utility pole is moved to the rebuilding place, each arm of the four jack devices is extended from the base of each jack, and the tip of each is positioned outside in the left-right direction of the loading platform. Next, each leg is extended downward to raise the vehicle body. Since each leg can be expanded and contracted independently, it can be easily leveled. When the base member is slid with respect to the gantry frame and the support portion is positioned on the outside of the loading platform, the base leg portion of the base jack device is extended to support the base member. Next, a temporary pole is attached to the support portion of the base member, and the utility pole rebuilding work is carried out.

After the construction is completed, the used tools will be loaded on the loading platform. Each base leg of the base jack device is retracted and the base member is slid to position the support inside the loading platform. Each leg of the four jack devices is shrunk and each arm is shrunk relative to each jack base. Then, it can be moved by the vehicle body.
