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

Embodiment 1

[0034] see Figure 4 , Figure 5 and Image 6 As shown, the present invention provides a device for measuring and controlling the crimping position of an aluminum crimping tube of a power transmission line, including a first clamping plate 5, wherein the first clamping plate 5 includes a clamping plate and a limit plate, and the limit plate is vertically fixed on the the clamping plate. The first clamping plate 5 is in an "L" shape, and one end of the clamping plate is connected to the ruler 4 in the "L" shape. In the specific implementation process, the main body of the ruler 4 is parallel to the clamping plate, so the The main body of the ruler 4 is provided with a length scale along the length direction, and the main body of the ruler 4 is distributed along the length direction with a T-shaped chute 41, and the sliding groove 41 is slidably connected with a T-shaped slider 42. Steel arms 43 are respectively fixed on both sides of the sliding block 42 . The opposite side...

Embodiment 2

[0040] see Figure 7 As shown, the difference between Embodiment 2 and Embodiment 1 is that two sliding blocks 42 are slidably connected to the scale 4, and steel arms 43 are respectively fixed at both ends of the two sliding blocks 42, and one steel arm 43 is used to record the end position of the connecting part 12 , and the other steel arm 43 is used to record the end position of the wire 3 .

Embodiment 3

[0042] see Figure 7 and Figure 8 As shown, another apparatus for measuring and controlling the crimping position of the aluminum crimping pipe of a power transmission line is provided. Compared with the second embodiment, the third embodiment improves the clamping of the steel anchor hanging ring 13 . Specifically, it includes a first clamping plate 5, the first clamping plate 5 is fixed to a fixing column 81, the fixing column 81 is fixed to a base 8, and a cylinder 82 is fixedly arranged on the base 8 relative to the fixing column 81, and the The second clamp plate 6 is connected to the air cylinder 82, the air cylinder 82 is connected to the air source through a two-position three-way valve, and the cylinder 82 is controlled to drive the second clamp plate 6 to move through the two-position three-way valve, so that all the The second clamping plate 6 and the first clamping plate 5 clamp the steel anchor hanging ring 13 .

[0043] The scale 4 is fixed on the first splint...

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...
