Description

[Detailed Description of the Invention] This invention relates to a pole metal fitting that allows easy attachment of a metal wheel used in striding work such as hanging telephone cables from the ground.

Recently, as part of telephone construction work, there has been an increase in maintenance reinforcement work and additional work such as cable suspension work and new installation work. For example, in the re-stretching work of the cable suspension line shown in FIG. 1, after attaching a plurality of movable metal wheels 1 shown in FIG. Construction work is being carried out through a new suspension line TN.
In addition, D is a hanging wire drum, P is a support column, and H is a towline.

Most of the work of installing this metal wheel 1 onto the existing suspension line T involved work at high places by climbing up and down ladders, and there was a high risk of the worker falling down, and there was also a large amount of time lost due to the climbing.

The present invention was devised in view of the above-mentioned current situation, and allows the metal wheel 1 to be easily attached to the existing suspension line T without having to go up and down a ladder, thereby reducing the danger of working at heights and saving labor. It is an object of the present invention to provide a rod metal fitting for attaching a metal wheel.

Next, an embodiment embodying the present invention will be described based on the drawings. In FIG. 3, the metal wheel mounting rod metal fitting 2 is composed of a rod part 21 made of non-conductive glass fiber or the like, and a mounting metal part 22 fixed to the upper end of the rod part 21. ,
It is built at a height of approximately 5.2m in total length. The mounting bracket part 22 is made of a fairly hard wire material such as No. 8 wire, and has an almost vertical rising part 22.
a, a supporting part 22b formed in a curved shape to support the metal wheel 1 in a straight line, and a holding part 22 formed in a fishhook shape to hold down the safety pin 13 of the metal wheel 1.
c and are integrally bent.

When using the above-mentioned rod metal fitting 2 for attaching the metal wheel, first place the cable roller 1 of the metal wheel 1 on the ground.
The supporting part 22b of the rod metal fitting 2 for attaching the metal wheel between 4
4, and while holding the hook 11 in the open state as shown in FIG.
1 on the existing suspension line T. That is, in that case, the rising part 22a of the mounting bracket part 22 lifts the entire metal wheel 1 in a hanging manner, the holding part 22b holds the metal wheel 1 from below, and the holding part 22c holds the metal wheel 1 with the safety pin. 13 is pressed and held in the opening direction of the pot 11. After the hook 11 is suspended on the existing suspension line T, by slightly turning the rod portion 21 to the right from the ground, the clamping portion 22c is released from the safety pin 13, and the safety pin 13 holds the hook 11 in the closed state. shall be. After that, attach the entire metal wheel mounting rod metal fitting 2 to the metal wheel 1.
The work is completed when it is dissociated from.

As described above, the metal wheel mounting rod metal fitting in this example has a simple structure and is easy to manufacture, and moreover, the metal wheel can be easily suspended on an existing suspension line by operating it on the ground. The work of attaching a metal wheel by going up and down a ladder as in the past can be omitted, there is no risk of falling accidents, and time loss associated with going up and down a ladder can be eliminated.

The present invention is a pole fitting for suspending a metal wheel from the ground to the cable suspension line via the hook, which has a hook that can be latched to a telephone cable suspension line and a safety pin that opens and closes the hook. The rod metal fitting consists of a rod part and a mounting metal part fixed to the upper end of the rod part, and the mounting metal part further includes a supporting part for supporting a metal wheel, and a clamping part for moving the safety pin to open and close the hook. This is a rod metal fitting for attaching a metal wheel, which is constructed in this way and has the following functions and effects. That is, the safety pin of the metal wheel is held in a pressed state by the clamping part on the ground in advance, and the metal wheel is raised to the position of the existing suspension line using the pole part while the lock is kept open, and the metal wheel is placed on the existing suspension line. It is possible to suspend the metal wheel via the hook, then rotate the mounting bracket via the rod section to separate the clamping section from the safety pin, close the hook, and safely suspend the metal wheel on the existing suspension line. Although it has a simple structure, it is possible to easily hang the metal wheel at a predetermined position at a high place, and it has the advantage of omitting the conventional work of climbing up and down a ladder, which is highly dangerous.
