Description

[Detailed Description of the Invention] [Industrial field of application] The present invention provides a utility pole in a place where a ladder cannot be used when a branch line such as an outdoor telephone line is pulled into a subscriber's house along a cable suspension line. It relates to a mounting tool that can be safely installed from the ground without suspending a cable suspension hanging bracket used to fix a drop line branched from an outdoor line on a cable suspension line stretched between them. is there.

[Conventional technology]

Generally, in the lead-in wiring work that connects telephone lines, power lines, and other outdoor lines to the inside of the subscriber's house, the branch line of the lead-in line branched from the outdoor line is connected to the cable suspension line between telephone poles via suspension metal fittings. Along the cable suspension line, hook the ladder on the cable suspension line with your hand and tighten it to attach it to the cable suspension line, then hook the drop wire connected to the cable with the connection terminal box on the cable to the suspension line and then pull it into the house. It is known that the cable suspension line is often hung on a ladder and climbed to work in high places.

[Problems to be solved by the device]

However, in conventional wiring work such as telephone work, workers have to use a ladder to get close to the reach of the cable suspension line, and it is necessary to attach it to a high suspension line where a ladder cannot be used. It is complicated because it requires a lift car or ladder for this construction, for example, the poles introduced in snowy areas are much higher than the longest used ladder, and the ground clearance of the cable suspension line is high. Since it is longer than the ladder length, it is not possible to use the ladder, or even if it can be used, it is common to hang the ladder in the air, and when working alone on the site, hold the lower end of the ladder and hang the drop wire on the cable suspension line while balancing. It was a very difficult task, and there was a problem in work such as being blown by the wind, and the danger of being fallen or slipping due to complicated use was extremely great.

The present invention properly eliminates these conventional drawbacks, and without attaching ladders to high cable suspension lines, without attaching to a high place and attaching hanging cable fittings for the drop line from the ground without working.
It is an object of the present invention to provide a mounting tool for a suspension fitting for a cable, which is easy to handle, has a simple structure, and is inexpensive, in order to eliminate dangerous construction work and significantly improve safety.

[Means for Solving the Problems]

Hook 125 _{1 that} engages the cable suspension line a from above as shown in
Since there is not, the supporting rod 101 can be slid smoothly.

Further, a method of removing the suspension metal fitting B already attached to the cable suspension line a from the ground will be described. First, as shown in FIG.
29 is switched to the reverse direction, the supporting rod 101 is held, and the mounting tool G is raised.

Then, the cable suspension line a is aligned with the inclined portion 134 ₁ of the guide portion 134 and the end surface of the hook bolt of the suspension metal fitting B along the inclined portion 134 ₃ .
The guiding the hook portion 15 by lowering the支杆101 downward and along the suspension bracket hook portion 15 of the B in the guide 127 ₁ along the inner side of the hook guide portion 127 to the pressing member 111, and a threaded portion 16 At the same time as guiding from the notched concave portion 107 ₁ of the socket 107 to the socket 107, the supporting rod 101 is slid in the direction H of FIG. 13 to fit the tightening nut 18 into the socket 107.

Finally, when it is confirmed that the suspension metal fitting B is pressed by the mounting tool G, the operation rope 104 is pulled downward, and the socket 107 is rotated in the reverse direction like the mounting tool F to tighten. The nut 18 is loosened to release the clamped state of the cable suspension line a, and the supporting rod 101 is lifted high from that state.

[Effect of device]

According to the present invention, a holding member provided at the upper end of a supporting rod is provided with a sliding rod having a lock engaging portion biased in one direction by a compression spring, and a suspending metal fitting for a cable is inserted into the sliding rod. A press-fitting member for receiving is provided, a socket for fitting and suspending a cable suspension fitting is provided at one end facing the press-fitting member, and a spindle having a ratchet mechanism is rotatably provided at the other end, and the ratchet mechanism is provided on the ratchet mechanism. A lock operation piece that connects the operation rope and that engages with the lock engagement portion and an operation rope is provided in the holding member, and a ratchet mechanism and a support shaft that rotate with the operation rope are used. The rotating socket is
By using a structure in which a tightening nut for tightening the grip member for the cable suspension wire in the cable suspension fitting is fitted and moved in the tightening direction, the cable suspension fitting is held in pressure contact and pulled to the cable suspension wire. The grip member can be attached to the cable suspension line by repeatedly hanging and pulling the operating rope and releasing the pressure contact, so you can climb to a high place without hanging a ladder on a high cable suspension line. It is possible to install hanging metal fittings for branch lines from the ground without doing anything, eliminating dangerous construction work and greatly improving safety, and it is possible to easily perform wiring work even in places where ladders cannot be used or in terrain In addition to eliminating the dangerous work between pillars, it is possible to attach suspending metal fittings for cables to the cable suspension line from the ground, so fixing operation does not take time, Single, there is the practical effect of that Tekisuru in wiring work by quickly can safely carry out aerial work.
