Description

[Detailed Description of the Invention] The present invention relates to a main rope holder for a fall prevention safety device for workers ascending and descending towers, ladders, and other high-rise structures.

Conventionally, this type of fall prevention main rope was used by directly tying its upper end to a steel tower or ladder, so the main rope near the top end was close to the structure such as a steel tower, and the safety device could not be activated. It was difficult to slide.

Furthermore, the work of attaching the parent rope required a great deal of effort.

It is an object of the present invention to eliminate such drawbacks and provide an improved parent rope holder that can easily attach the parent rope to a structure and maintain the required distance from the structure. That is the purpose.

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 has a frame 1 having an approximately U-shaped end surface.
A mounting hole 1 is drilled at a position close to the upper end of the body 5, a screw hole 8 is bored at a position close to the lower end of the body 5, and the threaded rod 3 having the member 2 is screwed into the screw hole 8. and the threaded rod 3
A band attachment part 9 is provided on the main body 5, and the band 4 having the tightening member 10 is attached thereto, and the rod body is bent into an approximate V shape and an approximate bellows-shaped crosspiece is fixed therebetween. The arm body 7 is provided with a plurality of hook coupling parts 6.
It has a structure in which the arm body 7 is fixed so as to protrude toward the opposite side of the main body 5 from which the member 2 protrudes.

Further, the frame 1 may have an approximately semicircular end face, or may be a square pipe.

To use the present invention, remove the scaffolding needle 12 from a predetermined position on the steel tower 11, fit it into the mounting hole 1, and then screw it onto the steel tower 11 again to align the main body 5 along the steel tower 11. and hang it.

Next, the band 4 is wrapped around the steel tower and fastened with the fastening member 10.

After that, when the threaded rod 3 is tightened, the lower part of the main body 5 tends to separate from the steel tower 11, and the band can be further tightened to fix the present invention to the steel tower.

In this state, the hook 1 attached to the tip of the main rope 13
4 is hooked onto an arbitrary rope joint 6 of the arm body 7, and the parent rope 13 is attached along the steel tower 11.

A worker working at high places fits the safety device (not shown) he carries with the main rope 13 to ascend or descend a high-rise object such as the steel tower 11, but as the worker moves up and down, the safety device also travels along the main rope. If a worker falls while moving up and down, the safety device grabs the main rope and stops the worker, preventing the worker from falling.

The present invention is constructed as described above, and can be easily installed using existing or newly installed scaffolding needles 12, and can be easily fixed using the band 4 and the tightening bolt 3.

Further, the parent rope 13 does not need to be attached by winding it around a steel tower or the like as in the conventional case, and the hook 14 attached to its tip can be attached to a length that allows it to engage with any desired mouth-to-pipe connection part 6.

Furthermore, the distance between the main rope 13 and the steel tower 11 can be adjusted by selecting an arbitrary rope joint 6 and engaging the hook 14, so that the safety device can be held in an appropriate position for ascending and descending. It has remarkable effects such as being able to move up and down smoothly.

FIG. 4 shows a second embodiment of the present invention, in which the arm body 7
This embodiment differs from the first embodiment in that the rope joint portion 6 is formed by using a plate material and providing a plurality of holes, but the other functions and effects are the same.

FIG. 5 shows a third embodiment of the present invention, which differs from the first embodiment in that the arm body 7 is provided with a protruding arm rod and has one or more rings attached thereto as a rope joint 6. However, other aspects and work effects are the same.

In addition, in the above embodiment, the band 4 is a belt and is fastened with a buckle as the fastening member 10, but it is possible to use a metal band or the like and fasten with a bolt. be.
