Anti-torsion device for uncoiling steel strand

Abstract

The invention discloses an anti-torsion device for uncoiling a steel strand. The anti-torsion device comprises a support body and anti-torsion rods, wherein the anti-torsion rods can rotate around the support body in the axial direction and are arranged at the end parts of the support body. According to the anti-torsion device, the anti-torsion rods connected with the steel strand rotate to release the restoring force of the steel strand during uncoiling; during rotation, the anti-torsion rods eliminate torsional stiffness and dead bends, generated during the uncoiling process of the steel strand, so as to avoid affecting the quality of the steel strand; meanwhile, manual eliminating of the torsional stiffness and the dead bends is not needed so as to avoid hurting workers and effectively improve the safety and reliability; the labor cost is lowered, and thus the uncoiling cost is lowered; the labor intensity of the workers is effectively reduced; the uncoiling time is reduced, and thus the uncoiling efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of steel strand deployment, and more specifically relates to an anti-twist device for steel strand deployment. Background technique [0002] At present, the steel strand reels are put together, and when the steel strands need to be used, the steel strand reels are placed on the pay-off frame, and the steel strands put on the coils are stretched into a straight line by a traction device. However, during the unfolding process of the steel strand, "twisting force" and "dead bending" will continue to appear, resulting in loose strands of the steel strand and even damaging the internal structure of the steel strand, affecting the quality of the steel strand. [0003] In addition, when the steel strand has "torsion" and "dead bend", it is necessary to manually strand the strand to eliminate the "torsion" and "dead bend" of the steel strand, but this is more likely to hurt the staff , the safety and reliability ar...

AI Technical Summary

Problems solved by technology

However, during the unfolding process, the steel strand will continue to appear "twisting force" and "dead bend", which will cause the strand to loosen and even damage the internal structure of the steel strand, affecting the quality of the steel strand

[0003] In addition, when the steel strand has "torsion" and "dead bend", it is necessary to manually strand the strand to eliminate the "torsion" and "dead bend" of the steel strand, but this is more likely to hurt the staff , the safety and reliability are low; moreover, it leads to higher labor cost, which makes the cost of exhibition and display higher, and the labor intensity of the staff is also higher

[0004] In addition, in the process of unrolling the steel strand, it takes extra time to manually eliminate the "torsion force" and "dead bend" of the steel strand, resulting in a longer unwinding time and lower unwinding efficiency
