At present, the phenomenon of wire breakage can occur in the stranding process of the steel wire rope. In view of the above problem, the chinese patent document with application number 201911316196.4 discloses a stranding machine, which includes a control cabinet, and a paying-off mechanism, a machine body, a pressing mechanism, an aligning and drawing mechanism, and a take-up mechanism which are sequentially arranged, wherein the machine body includes a frame and a multi-section barrel which is rotatably installed on the frame, the multi-section barrel is arranged in a line, a plurality of housings are fixedly installed on the frame, the housings and the multi-section barrel are distributed in a one-to-one correspondence manner, a support plate with an arc structure is connected to an outer wall of the barrel, a plurality of threading holes are formed on the support plate, a single-section barrel is installed in the housing corresponding to the single-section barrel, an insulating support is installed at the bottom of each housing, a power-on tube is installed on the insulating support, the power-on tube is located at one side of the barrel, and the power-on tube is electrically connected with the control cabinet through a power conductor wire. The steel wire breaking detection device can quickly detect the steel wire breaking initial stage, stop the machine in time, accurately reflect the section of the cylinder body where the broken steel wire is positioned, is convenient to repair, and greatly reduces the repair time.

The stranding machine can find the steel wire fracture under partial conditions, but after long-time production and use, the structural design has certain defects, and the defects are as follows:

1. the length of the broken end of the steel wire cannot be ensured, and if the steel wire at the broken end is too short, the steel wire cannot touch the metal pipe;

2. when the surface of the metal pipe is oxidized or greasy dirt exists, the steel wire touches the metal pipe and can not generate the action current required by the relay suction, so that the metal pipe needs to be cleaned at variable time;

3. with the continuous development of the technology, the running speed of the stranding machine is faster and faster, and the time for touching the metal pipe after the steel wire is broken is shorter and shorter, so that the relay cannot react and cannot be attracted;

4. the vibration of the equipment during operation easily damages the insulation of the metal tube, generates malfunction or fault, and increases the maintenance work.

Thus, a solution is urgently needed.
