Description

Technical Field

[0001] The invention relates to the field of steel strand manufacturing equipment, and in particular to a mobile steel strand bending and clamping combined tool. Background Art

[0002] As the load of distribution lines increases, the cross-section of conductors also increases. In order to meet the requirements for safe operation of the lines, the cross-section of the steel strands used for pulling wires at line terminals and corners is getting larger and larger, from 35 and 50 cross-sections to 80 and 100 cross-sections. As the cross-section of steel strands increases, the existing on-site pulling wire production tools can only meet the requirements for small cross-section pulling wires of 50 and below, and on-site production tools for large cross-section pulling wires have not yet appeared. Since large-section steel strands are more rigid, they are difficult to bend, and often require repeated bending to be successful, and it is easy to cause scratches on personnel. The bent steel strands and tongue plates are placed in the wedge-shaped wire clamp, and it is impossible to tighten them by manpower. They can only be done by hammering, which causes the galvanized layer of the wedge-shaped wire clamp to be damaged by the hammering, increasing the possibility of rust. The on-site wire pulling production is not only time-consuming and labor-intensive, but also the process requirements cannot be guaranteed.

[0003] The current on-site wire drawing equipment is single, especially for large-section steel strands, simple tools can no longer meet the requirements, and bending and clamping work is often done by manpower. Since large-section steel strands are rigid and difficult to bend, the work becomes more difficult and the efficiency is reduced. When clamping the bent steel strand, it is not easy to insert it into the wedge-shaped wire clamp together with the tongue plate, and it cannot fit tightly with the tongue plate, resulting in the wire drawing production quality and process level not meeting the requirements.
