By adjusting the rotating speed of the force adding device, the speed of the steel wire delivered to the winch by the force adding device is adjusted, and thus the tightness of the steel wire wound on the winch is adjusted.

[0033] As shown in Figure 1 , Figure 2 The utility model provides a steel wire force adding device, which comprises a fixed support 1, a guide wheel set 2, a brake disc 22, a brake caliper 3 and a controller 4. The fixed support 1 is made of a metal frame, and a cavity 11 is arranged in the fixed support 1 to protect the guide wheel set 2 and the steel wire inside the fixed support 1 and reduce external interference. The guide wheel set 2 is arranged in the cavity 11 and comprises at least two guide wheels 21. The steel wire is wound on the guide wheels 21 and moves together with the guide wheels 21 when the guide wheels 21 rotate, so that the steel wire is output from the force adding device. The guide wheels 21 are rotatably connected to the fixed support 1 and are installed on the fixed support 1 through a rotating shaft and a bearing. A plurality of guide grooves 23 are arranged on the guide wheels 21. In this embodiment, the guide grooves 23 are arranged in five rows, and the width of each guide groove 23 is 7 mm. The steel wire is wound in the guide grooves 23 of the two guide wheels 21 in sequence, so that the steel wire is wound on the guide wheel set 2 in multiple turns. The brake disc 22 is similar to an automobile brake disc and is installed on the rotating shaft of the guide wheels 21. The brake caliper 3 is an electronic brake caliper, and the tightness is adjusted through the controller 4. When the steel wire is not tightly wound, the brake caliper 3 tightly grips the brake disc 22 to reduce the rotating speed of the guide wheels 21. The brake disc 22 is installed on the rotating shaft of the guide wheels 21, the brake caliper 3 is installed on the fixed support 1, and the brake caliper 3 is arranged in cooperation with the brake disc 22.

[0034] In the process of guiding the steel wire, first, the steel wire is guided into the guide wheel set 2, and the steel wire is wound on the guide wheel 21. The fixed support 1 is respectively provided with a steel wire inlet and outlet, so as to ensure that the steel wire can smoothly enter and exit the device. When the steel wire is not tightly wound, the brake caliper 3 is controlled to brake, the brake caliper 3 tightly holds the brake disc 22, the rotating speed of the guide wheel 21 is reduced, and then the output speed of the steel wire is reduced, so that the winding speed of the steel wire is greater than or equal to the output speed of the steel wire, finally the steel wire is wound more tightly, the situation that the steel wire is easily embedded in the lower layer of steel wire in the winding process is reduced, the steel wire winding quality is improved, the situation of rework is reduced, and the work efficiency is improved. The brake disc 22 is installed on the rotating shaft of the guide wheel, and then the rotating shaft of the guide wheel is directly slowed down through the brake caliper, the structure of the brake wheel and the connecting shaft is reduced, the occupied space of the whole brake mechanism is reduced, the forced device is small in size and light in weight, and is convenient to transfer.
