Distribution network overhead line pole erecting and removing device

Abstract

The invention relates to the technical field of distribution network maintenance, in particular to a distribution network overhead line electric pole erecting and removing device. The device comprises a chassis and a control mechanism, and an electric pole channel disc is arranged on the front portion of the chassis; an electric pole root supporting mechanism is hinged to the upper surface of the base plate on the rear portion of the closed portion of the electric pole channel plate, telescopic holding arms are arranged on the two sides of the middle rear portion of the upper surface of the base plate respectively, and holding grippers are arranged at the ends of the telescopic holding arms; sliding rails extending from the outer portion of the closed opening of the electric pole channel disc to the periphery of the base plate are arranged in the middle of the upper surface of the base plate in the longitudinal direction, and sliding seats are arranged in the sliding rails and connected with the telescopic holding arms through coupling pieces. By means of the device, the safety and reliability of electric pole erecting and removing work can be effectively guaranteed, the mode of high-altitude electric pole moving is replaced with ground operation, the operation safety is remarkably improved, the operation links are optimized, the operation efficiency is improved, the electric pole does not need to be hoisted through a crane, the construction links are reduced, and the operation efficiency is obviously improved.

Description

technical field [0001] The invention relates to the technical field of distribution network maintenance, in particular to a vertical removal pole device for overhead lines of a distribution network. Background technique [0002] Distribution network overhead lines are the main form of distribution network lines at present. The overhead lines have a simple structure and are convenient for operation and maintenance. The distribution network project that erects or removes the electric pole. [0003] At present, the common erection and removal pole operations are divided into two methods: live construction or blackout construction. No matter which maintenance method is adopted, the erection or removal of the pole requires the cooperation of crane lifting. Taking the electrified Xinli electric pole as an example, first fix the wire rope at the appropriate position on the upper end of the pole, then use the hook to pull the wire rope and lift it to a height of 15 meters above the...

AI Technical Summary

Problems solved by technology

The above-mentioned operation method has potential safety hazards of falling objects from high places. No matter whether ordinary hoisting belts or steel wire ropes are selected, a firm connection point with the pole cannot be established. During the lifting process of the pole, sliding friction is likely to cause the pole to fall, which is harmful to people, Serious threat to power grid and equipment

On the other hand, during the process of the pole falling and fixing, it is necessary to manually rotate the pole to adjust the direction to meet the position of the wire and the cross arm. However, during the rotation of the pole, the personal safety of the workers cannot be guaranteed.
