Description

The present invention relates to a simple carrier transport device used for transporting materials used for construction work such as repairing the tower, replacing parts, etc. to a steel tower such as a power transmission line, and a method of transporting materials using the transport device. The present invention relates to a transportation device and transportation method using stretched power transmission lines.

Power transmission lines are supported by numerous steel towers and laid over long distances in order to supply electricity from power plants to remote locations. These power transmission lines and towers are regularly maintained and inspected. Among these, when maintaining and inspecting power transmission lines and steel towers located in mountainous areas, there are no roads along the power lines, making it difficult to transport replacement parts and other materials.

Therefore, conventionally, as in Patent Document 1, a cableway was provided from the bottom of a mountain to a desired location of a steel tower in a mountainous area, and necessary materials were transported to the steel tower by the cableway.

However, in order to provide such a cableway, it is necessary to cut down trees to create a road, and then install a cableway along the road, which requires time-consuming work. Therefore, instead of cutting down trees to cut a path and installing a cableway there, as in Patent Document 2, a system was developed that provided a transportation facility in which the main cable and tow cable were passed between steel towers.

In Patent Document 2, the main rope and tow rope are stretched in the air, and a carrier supporting repair materials is suspended from the main rope, and the carrier is moved along the main rope by being pulled by the tow rope. , repair materials transportation equipment for transporting repair materials, in which the main rope and tow rope are stretched between multiple existing power transmission towers and are supported by each power transmission tower. It is.

When the winch 19 is operated to wind up the transverse rope 13, the carrier transporter 1 is pulled by the transverse rope 20 and moves along the power transmission line A with the suspended load 23 lifted. For example, if the winch 19 is rotated in the opposite direction, it will be pulled by the horizontal hoisting rope 13 and move in the opposite direction.

Next, an example of a method for transporting materials using the simple carrier transport device of the first embodiment will be described based on FIGS. 6 to 12.

First, as step 1, as shown in FIG. A worker removes the counterweight and the like (not shown) while moving the spacecraft 24. At the same time, a loop-shaped rope obtained by folding the drawing rope 25 at the center is pulled and drawn by the above-mentioned spacer 24. When the wire extension rope 25 is stretched, a hanging metal wheel 26 is attached to the middle part of the power transmission line A to prevent it from hanging down.

Next, as step 2, as shown in FIG. 7, between the material transportation start point steel tower B1 and the material transportation arrival point steel tower B2, the extended rope 25 is replaced with a high strength special rope 27, and the end of the special strong rope 27 is changed. The parts (joints) will be able to be separated at one location on the steel tower B, the starting location for material transportation. After the special strength rope 27 has formed into a loop shape, the aerial vehicle 24 is returned from the transportation destination tower B2 to the material transportation starting location tower B1 while recovering the hanging wheel 26 attached to the intermediate location of the power transmission line A. . Further, at the material transportation destination steel tower B2, the folded portions of the special strength ropes 27 are respectively hung on a plurality of return wheels 22 provided at the upper part of the steel tower B2.

Then, as step 3, as shown in FIG. 8, the special strength rope 26 cut off at the material transport starting point steel tower B1 is used as the traversing rope 20, and one end thereof is connected to the tip of the board 4 of the carrier transporter 1. do. Further, as described above, one end of the hoisting transverse rope 13 is passed through the lifting wheel 15 of the base plate 4 of the carrier transporter 1, hung on the lifting wheel wheel 14, and then attached to the lower end of the base plate 4. Fix it. Further, the other end of the hoisting transverse rope 13 is hung on the metal wheel 18 provided at the top of the steel tower B1, lowered to the ground, and fixed to the winch 19.
