Description

[Technical field]

[0001] The present invention relates to the technical field of preventing conductors from falling off, and in particular to a protective rope for preventing conductors from falling off that is easy to operate. [Background technology]

[0002] The protective rope to prevent conductors from falling off is a safety device used in the maintenance and construction of power circuits, which prevents conductors from falling off when working at height and protects the safety of workers. Power transmission lines are the foundation of the power system, and in order to ensure the normal supply of electricity, it is necessary to carry out daily operation maintenance and inspection of power transmission lines.

[0003] In the conventional conductor fall prevention protective rope, a safety protection device to prevent the conductor from falling off must be installed before the worker at high altitude performs the work. In the original method, a wire rope (conductor protection rope) is used to perform fall prevention safety protection for the conductor, that is, the worker attaches the upper end of the wire rope to the cross arm side and then attaches the lower end of the wire rope to the conductor. This installation method is complicated and takes a lot of time, has low work efficiency, increases the safety risk of working at high altitude, and there is a risk that the wire rope will come into direct contact with the conductor after installation and cause friction, damaging the conductor. Therefore, in order to shorten the work time of the worker at high altitude, improve the work efficiency, and reduce the safety risk of the worker at high altitude, it is necessary to develop a protective rope that can quickly protect the conductor from falling off during inspection.
