The invention has the advantages of reasonable design, simple structure and convenient use. It can trim the wires, quickly thread the wires and correct the curvature of the tension clamp, improve the crimping quality of the compression tension clamp, and improve the work efficiency.

Description

technical field [0001] The invention relates to a method for fixing wires by a compression-type tension clamp. Background technique [0002] Such as Figure 13 As shown, the compression-type strain clamp is composed of a steel anchor and an aluminum tube; the wire passes through the aluminum tube, and then the steel core of the wire is connected to the steel anchor to realize the fixing of the wire. The front end of the aluminum tube is usually hydraulically operated by a hydraulic press and a steel mold, and it will be deformed, so that the compression type tension clamp and the transmission wire become a whole, so that the steel anchor and the steel core, the aluminum tube and the steel anchor, and the aluminum Friction and shear forces are created between the tube and the aluminum strands, and these forces create the grip of the Compression Strain Clamp. This compression-type strain clamp solves the problem that existing products cannot meet the requirements of overhead ...

AI Technical Summary

Problems solved by technology

The tension clamp must bear all the tension of the wire, so whether the crimping quality of the compression type tension clamp is qualified or not determines whether its grip can meet the requirements; once the traditional compression type tension clamp is hydroformed, it cannot be disassembled Replacement, if the bending degree of the wire clip exceeds 2% during the crimping process, it will not meet the requirements of the regulations. If the adjustment is made by beating, it will easily cause internal damage, greatly reduce the crimping quality, and it will be time-consuming and laborious. The quality of the crimping is unqualified, and there are potential safety hazards

[0004] It has been a long-standing problem to pass the transmission wire through the compression tension clamp. The outer diameter of the transmission wire is very close to the inner diameter of the aluminum tube of the tension clamp, which makes it very laborious to use manual methods to pass the transmission wire through the tube. Moreover, the irregularity and loose strands at the end of the transmission wire will aggravate this situation. The operation of passing through the pipe before construction of the transmission wire (steel core, aluminum strand) is subject to the opposite compression force of compression, and the transmission wire is flexible. , easy to bend, so how to ensure that the flexible metal is not easy to bend after receiving the compression force and convert the compression force into a radial force through the pipe is one of the difficulties in this project. At the same time, after the transmission wire is cut, the transmission wire is also prone to deformation , the cross-section of the power transmission wire may change from the original circular shape to an oval shape after being stressed, which makes it more difficult to penetrate into the aluminum tube; while the compression-type tension clamp needs to insert the power transmission wire into the aluminum tube before crimping. Among them, if the cutting is irregular or there are loose strands, it is not easy to repair, and it is extremely difficult to insert it in place manually

[0005] Fujian is located in a hilly area. Thousands of kilometers of high-voltage transmission lines span high mountains and thousands of towers stand among them. If it is serious, it will cause disasters such as wildfires, which will have great hidden dangers and affect the reliability of power supply of the power grid.
