Rapid pulling-out device for elbow type cable head and using method of rapid pulling-out device

Abstract

The invention discloses a rapid pulling-out device for an elbow type cable head and a using method of the rapid pulling-out device. The rapid pulling-out device comprises a fixing mechanism, a driving mechanism and a supporting mechanism, wherein the fixing mechanism comprises a first fixing piece and a second fixing piece, the top end of the first fixing piece is hinged to the bottom end of the second fixing piece, and the upper portion of the first fixing piece forms a cylinder matched with the horizontal part of the elbow type cable head; the driving mechanism comprises a mounting plate, the center of the end face of the mounting plate is fixedly connected with the top end of a hydraulic device, pull rods are symmetrically arranged on the two sides of the hydraulic device respectively, the top ends of the pull rods are fixedly connected with the mounting plate, and the bottom ends of the pull rods are detachably and fixedly connected with the first fixing piece; the supporting mechanism comprises supports which are parallel to the pull rods and arranged on the two sides of the hydraulic device respectively, and the bottom ends of the supports are connected with support bases which are connected with a box body of a power distribution cabinet; and a connecting plate is arranged between the two supports, and the bottom end of the hydraulic device is connected with the connecting plate in a sliding mode. With the rapid pulling-out device, cable head dismounting difficulty and the labor intensity of workers are reduced, working efficiency is improved, and the cable head and the box body of the power distribution cabinet are prevented from being damaged.

Description

technical field [0001] The invention belongs to the technical field of distribution network maintenance tools, and specifically designs an elbow-shaped cable head quick pulling device and a use method thereof. Background technique [0002] In recent years, with the rapid development of urban infrastructure, the cable rate of 10KV distribution lines has increased rapidly, and the plug-in cable terminals of distribution networks have continued to increase. At present, most cable heads use pre-cast cable heads, also known as elbow cable heads. Elbow cable heads generally adopt a negative pressure cavity structure, and are sealed with silicone grease during installation, which has good sealing, insulation and moisture-proof effects. [0003] When the equipment is overhauled and tested, it is necessary to separate the cable from the equipment, but after the cable head has been in operation for a long time, the silicone grease has aged, and it is extremely difficult to remove the ...

[0003] During equipment maintenance and testing, it is necessary to separate the cable from the equipment, but after the cable head has been in operation for a long time, the silicone grease has aged, and it is extremely difficult to remove the elbow cable head

Disassembly is usually done manually. For some equipment with a long service life, even if the equipment is not damaged by using tools such as crowbars and ropes, it requires the cooperation of multiple people. The disassembly is time-consuming and laborious, which increases the number of workers. Labor intensity and low work efficiency lead to longer power outages for users, lower user satisfaction, and damage the economic benefits of power supply companies
