Rapid butt joint device for insulating rod

Abstract

The invention discloses a rapid butt joint device for an insulating rod. The rapid butt joint device comprises a pipe body, sliding sleeves, a door-shaped knife switch, a shear type connecting rod assembly and a limiting pin assembly; the side surface of the pipe body is provided with a plurality of vertical cutting grooves and a first rotating shaft; the vertical cutting grooves are divided into an upper group and a lower group by taking the first rotating shaft as a reference; elastic clamping pieces are fixedly arranged in the cutting grooves and are pressed into the pipe body through elastic deformation to clamp and fix the insulating rod; the two sliding sleeves are both provided with second rotating shafts and slidably arranged at the positions of the upper group of cutting grooves and the lower group of cutting grooves in a sleeving mode correspondingly; the door-shaped knife switch comprises a cross beam part and two vertical beam parts fixedly connected to the left end and the right end of the cross beam part, first pin holes used for hinging the first rotating shaft are formed in the side faces of the vertical beam parts; the shear type connecting rod assembly is used for driving the sliding sleeves to slide in the pipe body through rotation of the door-shaped knife switch, and one end of each elastic clamping piece is pressed into the pipe body; and the limiting pin assembly is used for limiting and fixing the door-shaped knife switch in the locking position through a pin structure. The rapid butt joint device for the insulating rod is easy to disassemble and assemble, convenient to carry and suitable for the electric power overhaul working environment.

Description

technical field [0001] The invention belongs to the technical field of electric power construction or maintenance, and in particular relates to a quick docking device for insulating rods. Background technique [0002] The insulating operating rod link device is one of the indispensable safety tools in the maintenance work of power system transmission and distribution lines (including live work). At present, 10kV, 35kV, 110kV, 220kV, 550kV voltage level insulation rods generally use threaded butt joints. Due to the different thicknesses of the insulating rods, the butt joint threads between the two rods are also different. Only when the corresponding thread threads are consistent can the smooth butt joint be achieved. If a quick-joint insulating rod can be designed, the connection between the rods is simple and fast, and can be combined into a 10KV-500KV insulating operating rod at will, and the appliance that needs the end can be directly replaced during operation, which is...

AI Technical Summary

Problems solved by technology

The problem of this device is: (1) in the working condition that a plurality of power insulation operating rods are connected and lengthened, because the operation of the insulating rods often needs to be twisted or shaken, the clamping of the positioning piece on the insulating rods is easy to loosen, and the clamping is not firm enough, resulting in The insulating rod twists, which may easily cause misoperation; (2) the device is inserted into the insulating rods from both ends, and only one insulating rod can be locked at a time, and the connection between the rods is not fast enough and the efficiency is not high; (3) The device is difficult to unlock, and the unlocking operation is not convenient and fast enough, resulting in low efficiency during disassembly
