Abstract

PROBLEM TO BE SOLVED: To lessen the weight and size, to improve portability and also to reduce the fatigue caused by a working posture. SOLUTION: A suspending stage 8 is formed by connecting the opposite end parts of two parallel frames 1 to each other by shaft rods 2, by fitting a plurality of rollers 3 to the end parts of the shaft rods 2 respectively, by providing the two frames 1 with brakes 4 respectively, by providing virtually-U- shaped supports 5 vertically from the two frames 1 respectively, by linking the centers of the lower end parts of the supports 5 to each other in a bridging manner by parallel linking bars 6, by providing a plurality of belts between the linking bars 6 and also by providing a belt 7 for fastening the waist. Moreover, shoulder belts 9 are provided between the supports 5 and it is made possible to carry the equipment on the back by the belt 7 for fastening the waist and by the shoulder belts 9. Since a sitting posture is taken, according to this constitution, the supports 5 are made short and thereby the weight and size can be lessened. Besides, the sitting posture results in the reduction of fatigue. By providing the shoulder belts 9 between the supports 5, in addition, the equipment can be carried on the back and it is suited best to climbing to the site where a tower is built.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an airborne vehicle that is used by embarking on a power transmission line for maintenance and repair work on the multiconductor power transmission line.

[0002]

Therefore, the present invention solves the problem by reducing the weight and the bulk, improving the transportability, and changing from the standing working position, which is the cause of fatigue, to the sitting position. is there.

[0003]

As shown in FIGS. 1 to 5, the present invention has a sitting posture, so that the columns 5 and 5 can be set short, and the weight and bulk can be reduced. Since the bulk can be reduced, the shoulder straps 9 are provided between the stanchions 5 and 5 in order to carry them all at once without the need for a split structure (the weight of individual items is lighter if split, but it requires manual labor). ..

[0004]

2. Description of the Related Art Conventionally, this type of aerial vehicle is constructed by simply suspending columns on a horizontal frame as shown in FIGS. 6 and 7. Although it has a structure that can be divided, it is heavy, bulky, and poor in transportability. there were. In addition, the worker who goes out has a high center of gravity because he / she takes a standing posture for a long time, which is not stable and causes fatigue.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS To explain the embodiment of the present invention in detail, as shown in FIG. 1 to FIG. 5, two frames 1, 1 parallel to each other are arranged, and both end portions of the both frames 1, 1 are respectively arranged. The shafts 2,2 are connected to each other by a plurality of rollers 3,3, respectively.
The brakes 4 and 4 are installed on the both frames 1 and 1, and the electric wire is pressed to stop the movement due to the friction resistance of the sliding contact with the brake rubber. Each of the U-shaped columns 5 and 5 is hinged at one end,
The other end is provided so as to be detachable so as to be detachable, and bridge-connected by connecting bars 6, 6 parallel to the lower end centers of the columns 5, 5.
Place multiple belts between 6 and
The belt with the buckle 71 and the long belt 72 are attached to form the boarding platform 8, and the shoulder belt 9 is provided between the columns 5 and 5.

For the columns 5 and 5, a steel pipe is bent into a substantially U shape, a hole is provided at one end, and a U-shaped metal fitting welded to the frame 1 is pivotally attached to the other end. In the case of, a fitting / removing plate provided with a dharma-shaped hole is rotatably attached to a shaft through a U-shaped metal fitting, and the fitting / removing plate is removably provided in a stepped bolt provided in the frame 1. On one or both of the two fitting / removing plates,
A hole is provided below the dharma-shaped hole, a hole is also provided in the frame 1 corresponding to this hole, and the engagement pin is penetrated to prevent the disengagement.

When carrying the air vehicle of the present application, as shown in FIG. 5, pass the arm through the shoulder belt 9 like a backpack,
The pad 91 is put on the shoulder, and the length is adjusted by the length adjusting ring 92. Then, the waist wrapping belt 7 is rotated around the waist and the long belt 72 is fitted and tightened on the buckle 71 located on the abdomen side, whereby the belt is firmly attached to the back. The connecting bars 6 and 6 are slightly bent so that the shoulder bars of the human body can be avoided when carrying them on the back. A plurality of belts provided between the connecting bars 6 and 6 hit the back to distribute the load.

[0008] As described above, the transportation is carried to the steel tower on the mountaintop or on the mountainside, and the power transmission line is mounted on it.
Pull out the engaging pin of the air carrier carried on the power line,
Remove the fitting / dismounting plate from the stepped bolts in Fig. 3, keep the columns 5 and 5 rotated downward, put the roller 3 on the power transmission line in that state, and rotate the columns 5 and 5 again to fit them. Fit the Dharma hole of the de-plate to the stepped bolt and engage the engagement pin. Next, the ropes 11 (broken lines in Fig. 4) are connected to the brakes 4, 4 to complete the riding. Then, as shown in FIG. 4, the worker sits on the platform 8 and the rope provided between both brakes 4, 4.
When the foot 11 is pushed down, the brakes 4, 4 rotate and the brake pad presses the power transmission line and stops.
In addition, Fig. 4 shows the case of mounting on a two-conductor power transmission line, but in the case of a four-conductor or six-conductor power transmission line, it is mounted on the upper two conductors to inspect the power transmission line and the spacer. Yes, at the spacer, the worker puts his foot on the stirrup belt 10 and moves up to the power transmission line, lifts the aerial vehicle and puts the roller of the aerial vehicle on the position beyond the spacer to perform the work. It is a thing. In addition, the stirrup belt 10 supports the safety belt
You can hang it between 5 or use a rope,
It suffices if the length can be adjusted according to the physique of the worker.

[0009]

As described above, since the air vehicle of the present application is in the sitting posture, the stanchions 5, 5 can be set shorter, and the weight and the bulk can be reduced as compared with the conventional product. In addition, the sitting posture increases the sense of stability and reduces fatigue during work. Further, by providing the shoulder belt 9 on the back surface of the platform 8, the platform 8 and the backpack are formed on the front and back sides, and the number of parts can be reduced. When carrying it on a back, it is attached to the back in a stable state by the waist wrapping belt 7. Moreover, both hands of the worker are free, and can be safely transported when climbing a mountaintop or a steel tower standing on a mountainside.
