Is going.

[0003]

[Problems to be Solved by the Invention] The above-mentioned erected case
Work to remove the Bull and gold car is a danger become the aerial work platforms,
Moreover, the cable after installation is heavy and tension acts.
From it, the effort to remove this large, also affects the erection efficiency of the cable. By the way, the gold wheel of the present invention is 15 mate
If you install cables at intervals, one piece of gold
About 100 ▲ kilogram load on the car
Has been confirmed. Therefore, according to the present invention, the pulley shaft is erected by rotating it from the frame body by the operation from the ground.
It is an object of the present invention to improve the operability by making it possible to easily remove the cable or the like.

[0004]

Means for Solving the Problems The present invention meets the above-mentioned object. The hook of the frame main body can be freely detached from a support wire stretched between electric poles, and the frame is erected at the lower bifurcated portion of the main body. A cable erection wheel, which is constructed by passing a shaft of a pulley that moves by carrying a cable for cable or a erection rope connected with the cable, and is supported by one lower part of the bifurcated portion so as to be freely bent outward. A shaft support piece is provided, a shaft insertion groove formed by cutting from the lower end is formed on the other side of the bifurcated portion, and a shaft that is axially supported by the shaft support piece and is fitted into the shaft insertion groove from below is attached to the bifurcated portion. I put a pulley into it,
On the supporting shaft provided on the upper outer surface of the shaft insertion groove on the other side of the bifurcated portion, a hook-shaped piece holding the shaft is provided below the lever type operation piece that is swingably supported. It is characterized in that a hooking piece to be operated is provided.

[0005]

According to the present invention, the shaft 7 of the frame body 1 having one end supported by the hook-shaped piece 11 of the lever type operation piece 10 as shown in FIG.
Is to support and move the erection cable or the erection rope b connecting the cable to the pulley 8 which is pivotally supported. However, in order to remove the erection cable from the pulley 8, it is not necessary to climb with a ladder as in the past. Then, the hook piece 12 of the lever type operation piece 10
Is pulled from the ground by a hook fixed to a long rod, and the hook-shaped piece 11 is removed from the shaft 7 as shown in FIG. At this time, the pulley
The shaft piece 5 supporting 8 is attached to one lower part of the bifurcated portion.
The shaft is set so that the pulley 8 is largely bent outward by its own weight.
Since it is supported, the cable after installation is completely from the pulley 8.
Leave.

1 and 2 illustrate the present invention, which comprises a bifurcated frame body 1 and a hook 21. The frame body 1 corresponds to a right-side piece 2 and a left-side piece 3 which are symmetrical to each other. The joint piece 17 of the joint piece 16 is sandwiched between the pieces 2a and 3a and fixed, and the lower portion of the right piece 2 has a shaft support piece 5 rotatably supported by the shaft 4 (see FIG. 3). Is provided, and a shaft insertion groove 6 cut from the lower end is formed in the left piece 3, and the bifurcated shaft 7 is pivotally supported by the shaft support piece 5 and fitted into the shaft insertion groove 6 from below. A drum-shaped pulley 8 which fits in the shape portion is fitted, a support shaft 9 is provided on the upper outer surface of the shaft insertion groove 6, and the center portion of the lever type operation piece 10 is pivotally supported on the support shaft 9.

A hook-shaped piece 11 for holding the shaft 7 from the side is provided below the lever type operation piece 10, and a hook piece 12 operated from the ground is provided above the hook-shaped piece 11. A coil winding spring 13 is fitted on the support shaft 9, and one end of the spring 13 is attached to the left piece 3
, And the other end is hooked on the hook-shaped piece 11, and the lever-like operation piece 10 is held in the posture of FIG. 2 by its elasticity.

The hook 21 has a well-known structure, and an opening / closing piece 22 for freely opening and closing the entrance of the hook 21 is rotatably supported by a shaft 23. An operating rod 24 is axially connected to the upper end of the opening / closing piece 22. The locking projection 25 formed on the lower surface of the hook 21
When the ring 26 at the end of the operating rod 24 is pushed up from the ground by engaging with the pin 27 below the pin 27, the engaging projection 25 is disengaged upward from the lower pin 27, and the operating rod 24 is placed above the hook 21. The excessive movement is restricted by 28, and the hook 21 can be removed from the support wire a or the like stretched between the electric poles.

The joint piece 16 is provided with a connecting piece 17 below the rectangular frame piece, and a joint piece 18 having a shape almost opposite to the joint piece 16 is fixed below the opening / closing piece 22 of the hook 21. The tops of the joint pieces 16 and 18 are rotatably connected by screws 19.

In this embodiment, as described in the section of the operation, the hooking piece 12 of the lever type operating piece 10 is pulled from the ground by a tool to remove the erection cable b from the pulley 8.

[0012]

[Effect of the invention] The present invention is configured as mentioned above, will be working, or erection cable from pulley cable erection for gold car
The operation to remove the erected cable can be done from the ground.
As well as to easily perform as Te, there is an effect that can significantly improve the efficiency of the erection work.
