Power transmission tower-oriented cable erecting device with joint protection function

Abstract

The invention belongs to the technical field of power equipment and relates to a power transmission tower-oriented cable erecting device with a joint protection function. The device comprises a shell, a limiting column is fixedly connected to the outer surface of the shell, a limiting plate is slidably connected to the outer surface of the limiting column, a fixing column is fixedly connected to the outer surface of the limiting plate, the outer surface of the fixing column is movably connected with a fastening strip, and the interior of the shell is fixedly connected with a mounting seat; when the limiting plate slides on the outer surface of the limiting column, part of acting force borne by an electric wire is transferred to the limiting plate and the limiting column, and when the limiting plate and the limiting column slide relative to each other, the transferred force is offset under the action of a fastening spring between the limiting plate and the limiting column, so that the acting force can act on the electric wire as little as possible, and therefore, the outer surface of the joint between the electric wire and the shell is prevented from being abraded more seriously when the wire shakes, and the situation of safety accidents caused by electric leakage is avoided.

Description

technical field [0001] The invention relates to the technical field of electric power equipment, in particular to a cable erection device for a power transmission tower with a connection point protection function. Background technique [0002] The transmission tower is the supporting point of the overhead line. The transmission tower is used to erect the line to connect the power to thousands of households. The transmission tower is to fix the cable on the transmission tower through the cable erection device, and the cable can be flexibly moved through the erection device It is fixed on the transmission tower, which is convenient for the erection work of the electric staff and improves the erection work efficiency of the staff. [0003] However, when the existing iron tower cable erection device is in use, the cable will swing slightly with the wind when encountering strong winds, and birds will often stay on the cable on the cable erected in the wild, which will cause damag...

Problems solved by technology

[0003] However, when the existing iron tower cable erection device is in use, the cable will swing slightly with the wind when encountering strong winds, and birds will often stay on the cable on the cable erected in the wild, which will cause damage to the cable connection. Increased force will easily cause wear and tear and leakage and lead to safety accidents. Therefore, those skilled in the art provide a cable erection device for transmission towers with a connection protection function to solve the problems raised in the above-mentioned background technology
