Problems solved by technology

However, in the actual work process, on the one hand, the insulating ladder is hung on the cross arm or wire during maintenance. On the other hand, because the power lines are erected on the poles, the power management department often needs to use ladders when overhauling the power lines, but most of the ladders currently used are traditional ladders, and electric power maintenance personnel are using traditional In the process of overhauling the power line with the type ladder, because there is no good fixing device between the ladder and the utility pole, and the ladder itself does not have a good fixing device, it is easy to cause the electric maintenance personnel to slip and fall during the maintenance. Threat to the life and property safety of electric maintenance personnel

Abstract

The invention belongs to the technical field of the power line repairing and maintaining equipment application and in particular discloses a crawling ladder for repairing and maintaining a power line. The crawling ladder is composed of a locating assembly and an insulated climbing assembly. The crawling ladder for repairing and maintaining the power line has the beneficial effects that the crawling ladder has a simple structure, can be assembled and used conveniently, has long service life, and can effectively improve the repairing and maintaining efficiency; when the crawling ladder is used, a pulley on a hook can be clamped into a lead wire, a connecting rod is driven by the dead weight of the device, so that a driving connecting rod and a locating block can move downwards by taking the connecting point of a locating plate and the hook as the center, one end of the locating plate is drive to move upwards, and the buckling (padlocking) purpose can be achieved, the connecting stability of the hook and the wire is ensured and no slipping phenomenon is caused.

Description

technical field [0001] The invention belongs to the technical field of electric power maintenance equipment application, and in particular relates to a climbing ladder applied to power line maintenance. Background technique [0002] In order to ensure the safety and stability of the power grid, ensure the normal operation of transmission and distribution lines, and improve the reliability of the power grid, live work is generally used. The insulating ladder is one of the important work tools for live work, and has been widely used in electric work. An insulating ladder with a traditional structure generally includes a ladder body and an insulating material coated on the surface of the ladder body. The use of the traditional structure of the insulating ladder is the same as that of the ordinary ladder. When using it, it is only necessary to lean the insulating ladder against the equipment to be inspected. However, in the actual work process, on the one hand, the insulating ...
