Description

Technical Field

[0001] The invention relates to the technical field of steel wire rope processing, and in particular to a tightening device for steel wire rope production. Background Art

[0002] Steel wire rope is a spiral steel wire bundle twisted together according to certain rules with steel wires that meet the requirements of mechanical properties and geometric dimensions. It is mainly composed of steel wires, rope cores and grease. The production process of steel wire rope is to first twist multiple layers of steel wires into strands, and then twist a certain number of strands into a spiral rope with the rope core as the center. When the steel wire rope does not rotate or hardly rotates around the longitudinal axis, this kind of steel wire rope is a non-rotating steel wire rope; this characteristic is caused by the opposite twisting directions of the inner and outer strands.

[0003] When a load is applied to a non-rotating wire rope, the torque generated by the rope core is opposite to the torque generated by the outer strands, thus forming a balance. During the production process of the wire rope, a tightening device is needed to tighten it for workers to process it. However, currently, a tightening device can only tighten one wire rope. When multiple wire ropes need to be tightened at the same time, multiple tightening devices need to be assembled on site, which is not convenient to use. Therefore, a tightening device for wire rope production is proposed, which can not only tighten one wire rope, but also tighten multiple wire ropes. Summary of the invention

The opening directions of the cylindrical cavity of the right fixing block 17 and the threaded cavity of the left fixing block 18 are opposite and located at the same center. On the line, both ends of the locking rod 19 are provided with threads, and the end of the first end of the locking rod 19 is connected with a locking plate 20.
