Description

[Detailed Description of the Invention] The present invention relates to a main rope attachment device that is attached to the top of a high-rise structure such as a telephone pole, and is used to attach a main rope to be used by workers ascending and descending such high-rise structures to prevent falls.

Traditionally, power transmission line towers have been equipped with fall prevention devices for lifting and lowering them, but workers climbing and lowering power distribution line poles were left defenseless, resulting in many falls.

Therefore, even when going up and down utility poles, a safety line is used to prevent falls, and the safety line is attached or detached remotely from the ground using a control rod, etc. A fixture to connect the main rope has become necessary.

In view of the current situation, it is an object of the present invention to provide a main rope attachment that can be attached to the top of a utility pole.

Aspects of the present invention will now be described in detail with reference to an embodiment illustrated in the accompanying drawings.

As shown in the figure, this embodiment includes two bands 3 and rings 6 and 2.
The band 3 is made up of two bolts and nuts 7 and 8, and the band 3 has port holes 1 and 1 at both ends, and the center part is curved 2 to one side and is used in two directions.

The ring body 6 is reinforced by connecting both ends of a rod bent into a U-shape with a plate having holes for the insertion of bolts 7, and at the same time hooks a hook 9 attached to the tip of the master rope 10. A hooking hole 4 is formed for this purpose, and an abutment member 5 for abutting against a utility pole or the like is welded to the plate side.

The two bolts and nuts 7.8 are for fastening the bands 3, 3 and for connecting the band 3 and the ring body 6.

Said ring 6 is connected to one of the two bands 3, 3 via a bolt/nut 7.8.

To use the present invention, as shown in Fig.
A ring body 6 is attached to the top of the utility pole 1 using bands 3, 3 and bolts and nuts 7.8, and when a malfunction occurs on the pole and the worker needs to go up and down, the worker can The main rope 10 is brought to the site, and the hook 9 attached to the tip of the main rope 10 is connected to the ring 6 attached to the top of the utility pole using a remote control rod (not shown), and the main rope 10 is guided along the utility pole 11. Install it.

After that, the worker 12 tightens the safety belt 1 worn on his body.
3, fit and insert the safety device 14 that is attached to the main rope 10,
In this state, go up and down the telephone pole.

As the worker moves up and down, the safety device 14 also moves up and down along the main rope 10, and if the worker is about to fall during the movement, the safety device 14 immediately grabs the main rope 10 and stops, stopping the worker. to prevent falls.

After the pole work is completed and the worker returns to the ground, he or she retrieves the main rope 10 using the remote control rod.

The present invention is constructed as described above, and the rope is permanently attached to the top of the utility pole, and the main rope can be attached and detached when the pole needs to be raised or lowered for work.Since the structure is simple, it can be provided at low cost and in large quantities. In addition, since the hooking hole 4 of the ring body 6 is formed relatively large, it can be easily operated when the main rope is hooked remotely.

In addition, since the ring body 6 is provided with a support member 5 that is in contact with a telephone pole, etc., it has practical effects such as being strong and safe without being deformed even under the impact load when restraining a fall. be.
