[0002] With the widespread use of wire ropes, the market demand for wire rope stranding machines is also increasing. Safer and more reliable wire rope stranding machines are generally sought after by customers.

[0003] During the stranding process of the wire rope stranding machine, the main problem is that wire breakage may occur during the stranding process due to differences in the quality of the raw material wire or differences in heat treatment. Therefore, a wire breakage detection device is usually installed between the traction device and the wire take-up device. The traditional wire breakage detection device includes a ring-type wire breakage stop device or a light bar-type wire breakage stop device, which is relatively conventional, but has a simple structure and is very effective in use.

[0036] In a preferred embodiment, the detection mechanism 2 includes a first semicircular ring plate 21, a second semicircular ring plate 22, a first arc plate 23 and a second arc plate 24; the vertical sections of the first semicircular ring plate 21, the second semicircular ring plate 22, the first arc plate 23 and the second arc plate 24 are all arranged in a fan-shaped ring shape; the axes of the first semicircular ring plate 21, the second semicircular ring plate 22, the first arc plate 23 and the second arc plate 24 are all coincident with the axis of the cylinder 1; the first semicircular ring plate 21 is symmetrically arranged at the top and bottom of the cylinder 1; the outer diameter of the first semicircular ring plate 21 is equal to the inner diameter of the cylinder 1; the axial length of the first semicircular ring plate 21 is equal to the axial length of the cylinder 1;

[0051] How this application works:

[0052] When installing or removing the detection mechanism 2, first pull the cover plate 3 to make the cover plate 3 move away from the cylinder 1 along the diameter direction of the cylinder 1, and the pressure plates 33 at both ends of the third arc plate 31 move away from the cylinder 1 synchronously, and the pressure plate 33 drives the pressure strip 15 in contact with it to move away from the fixed block 11, and the spring 16 between the pressure strip 15 and the corresponding fixed block 11 accumulates elastic force. When space is left between the cover plate 3 and the corresponding installation groove 12, the detection mechanism 2 is inserted or pulled out along the axial direction of the cylinder 1. If it is inserted: after insertion, the first arc plate 23 and the second arc plate 24 are located in the corresponding installation groove 12, and then the cover plate 3 is released, and the spring 16 is released The elastic force drives the pressure strip 15 to approach the fixed block 11. At this time, the pressure strip 15 presses the pressure plate 33 so that the pressure plate 33 is pressed tightly against the outer wall of the adjacent fixed block 11, so that the cover plate 3 is tightly covered on the first curved plate 23 and the second curved plate 24, so that the first curved plate 23 and the second curved plate 24 are located in the mounting groove 12 without shaking or moving; if it is to be pulled out: the first curved plate 23 and the second curved plate 24 are moved out of the corresponding mounting groove 12, and then the cover plate 3 is released, and the spring 16 releases the elastic force to drive the pressure strip 15 to approach the fixed block 11. At this time, the pressure strip 15 presses the pressure plate 33 so that the pressure plate 33 is pressed tightly against the outer wall of the adjacent fixed block 11.
