Description

Technical Field

[0001] The invention relates to the technical field of tension crossarm replacement, and in particular to an operating device for tension crossarm replacement. Background Art

[0002] The function of the crossarm is to fix the angle iron horizontally on the top of the pole with a porcelain bottle on it, which is used to support the overhead wires. The crossarm is an important component of the pole tower. Its function is to install tension crossarms and hardware to support the conductors and lightning conductors, and to keep them at a certain safety distance as required. The tension crossarm is a type of crossarm. At the same time, due to the aging of the tension crossarm after years of use, the tension crossarm may break, affecting the normal use of the tension crossarm, and there is also a risk of falling off, so the tension crossarm needs to be replaced.

[0003] At present, the existing methods of replacing tension crossarms mostly involve lowering the conductors on the tension crossarm to be replaced to the ground, thereby vacating the tension crossarm, and then removing the old tension crossarm and replacing it with a new one. After that, all the conductors lowered to the ground are installed and hung on the new tension crossarm to complete the replacement of the tension crossarm. This method of replacing tension crossarms is relatively cumbersome and also affects the normal operation of the transmission line being crossed.

[0004] To this end, in response to the above problems, we propose an operating device for replacing tension crossarms. Summary of the invention
