A device for measuring and controlling the crimping position of an aluminum crimping tube of a transmission line

Abstract

The invention discloses a device for measuring and controlling the crimping position of an aluminum crimping pipe of a power transmission line, comprising a first clamping plate, wherein the first clamping plate is in an "L" shape, and one end of the first clamping plate is connected with a scale in the "L" shape, A sliding block is slidably connected to the scale, and steel arms are respectively fixed at both ends of the sliding block; a second clamping plate is arranged opposite the first clamping plate, and the first clamping plate and the second clamping plate clamp the steel anchor hanging ring , one end of the steel anchor hanging ring is pressed against the limit plate of the first splint; connected to the connecting part of the steel anchor hanging ring, the steel anchor connected to the connecting part passes through the pipe along the length of the scale direction extension. In the present invention, by aligning the steel arm with the end of the connecting portion or the end of the wire, when the aluminum crimping pipe is sleeved on the connecting portion, the outer wall of the aluminum crimping pipe can be pressed against the steel arm by pressing the steel arm. Leave traces, and squeeze the aluminum crimping tube according to the traces, so as to avoid the occurrence of leakage or overvoltage of wires or connecting parts.

Description

technical field [0001] The invention relates to the field of cable connection auxiliary devices, in particular to a device for measuring and controlling the crimping position of an aluminum crimping tube of a power transmission line. Background technique [0002] The continuation of transmission line conductors often requires aluminum aluminum crimping pipes to connect the steel anchors and the conductors. On the one hand, the aluminum crimping pipes enhance the connection strength between the steel anchors and the conductors. Small resistance at the connection to avoid heating at the connection during power transmission. [0003] In the prior art, such as figure 1 The steel anchor 1 includes a steel anchor hanging ring 13 , a connecting part 12 connected to the end of the steel anchor hanging ring 13 , and a steel anchor through pipe 11 connected to the end of the connecting part 12 and connected to the wire steel core 31 . The aluminum crimping tube 2 is sleeved on the w...

AI Technical Summary

Problems solved by technology

Generally extruded aluminum crimping pipes are often manually extruded by construction personnel through special hydraulic pliers. During the extrusion process, the relative position of the connecting part 12 and the aluminum crimping pipe is often checked by visual inspection. Confirm, and then press through the hydraulic pliers. However, due to the inaccuracy of visual inspection, when the aluminum crimping tube is connected, there will often be overpressure or leakage at the connection part and the wire. Once there is an overpressure or leakage The situation, either affects the connection strength of the aluminum crimping tube, or affects the contact area of ​​the wire, forming a high resistance at the connection, which is prone to heat
