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, hang the ladder on the cable suspension line and tighten the suspension bracket to the cable suspension line by hand, then hook the branch line connected to the cable with the connection terminal on the cable and hook it into the suspension system and then pull it into the house. It is known that, in many cases, a ladder is hung on the cable suspension line, and the cable is used to climb and work at a high place.

[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 and ladder for this construction, for example, the poles introduced in snowy areas are much higher than the longest ladders that are often used, and the ground clearance of the cable suspension line is high. The ladder cannot be used because it is longer than the ladder length,
Even if it can be used, it is often the case that the ladder is suspended in the air, and when working alone in the field, it is extremely difficult to hang the drop wire on the cable suspension line while holding the bottom edge of the ladder while balancing, and it is difficult to wind. However, there is a problem in work such that the work is complicated and the risk of falling or slipping due to complicated use is extremely great.

The present invention properly eliminates these conventional drawbacks, and installs suspension metal fittings for branch lines from the ground without hanging ladders on high cable suspension lines and without working on high places.
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.
