Abstract

The invention discloses an auxiliary device for crimping and piercing pipes of overhead power transmission lines. A symmetrically arranged first column is arranged in the middle of the base, a second column is arranged on one side of the first column, and a first support arm is arranged on one side of a slider; One side of the tool is provided with a first sleeve, and one end of the first sleeve is installed inside the connecting ring; the clamping device includes a double-ended stud whose two ends rotate in opposite directions, a first ratchet fixedly installed in the middle of the double-ended stud, The first pawl installed on one side of the first ratchet and the wrench installed on one side of the first pawl, the middle part of the double-ended stud is movably installed on the upper end of the first column, and the two ends of the double-ended stud are threadedly connected with the slider . When the present invention is used, the aluminum stranded wire is clamped inside the clamps on both sides, the connecting pipe is arranged between the aluminum stranded wires on both sides, and the wrench is pressed to make the double-ended stud drive the clamp to slide to the middle, so that the aluminum stranded The wires are threaded into the splicing tube symmetrically, which improves the efficiency of wire crimping and ensures the accuracy of the aluminum stranded wire passing through the tube.

Description

technical field [0001] The invention belongs to the technical field of cable crimping, in particular to an auxiliary device for crimping and piercing pipes of overhead power transmission lines. Background technique [0002] Before the hydraulic construction of overhead transmission line projects, substation engineering conductors or ground wires, it is necessary to pass the wires into the crimping tubes by considering different pre-bias values ​​according to the different hydraulic tube materials, wall thicknesses, and crimping methods. "Overhead Conductors for Power Transmission and Transformation Projects (800mm 2 and below) and ground wire hydraulic crimping process regulations "DL / T5285-2018, section 8.1.1 wire splicing tube crimping process requirements "Push the aluminum tube of the splicing tube into the tube along the twisting direction of the aluminum wire, and align with the positioning Marking coincides". At present, manual pipe threading is basically used in th...
