DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 , the utility model provides a technical solution: the utility model provides a compressing mechanism of a winch rope rewinding machine;

[0024] like Figure 1 and Figure 3 The figure shows a machine body 1, which is characterized in that: an electric push rod 7 is fixedly connected to one side of the bottom of the machine body 1, and the electric push rod 7 drives a slider 10 fixedly connected to the bottom of the support frame 6 to move in the slide rail 9 at the bottom of the machine body 1. A motor 5 is fixed on the top of the support frame 6, and the motor 5 drives the fixing mechanism 2 to rotate. The fixing mechanism 2 includes a U-shaped block 205, and the U-shaped block 205 fixes both ends of the rotating shaft 201. Four key grooves are opened at both ends of the rotating shaft 201. One end of the fixing spring 202 is fixedly connected inside each key groove, and the other end of the fixing spring 202 is fixedly connected to the top block 203. A threaded hole is opened at both ends of the recovery roller 3, and the U-shaped block 205 is connected to the recovery roller 3 through a threaded rod 204.

[0025] In the above scheme, a small section of the slide rail 9 is opened on one side of the bottom of the body 1. The slide rail 9 cooperates with the slider 10 and the electric push rod 7 to form a moving adjustment system. The electric push rod 7 is used to move the support frame 6 to conveniently and quickly replace the recovery roller 3.

[0026] like Figure 2 As shown, a detachable and installable clamping mechanism 4 is arranged above the recovery roller 3, and the clamping mechanism 4 comprises a clamping block 401, a clamping spring 402 and a top plate 403 are fixedly connected at the top of the clamping block 401, and both ends of the top plate 403 are fixed to the top of the machine body 1 by screws 404, and the clamping spring 402 is initially in a compressed state; a plurality of groups of clamping blocks 401 are arranged.

[0027] In the above scheme, the pressing block 401 is initially very close to the recovery roller 3, and each pressing block 401 can work independently without affecting each other. Each group of pressing blocks 401 can be disassembled and assembled by screws 404 on both sides. The compression spring 402 and the pressing block 401 form an elastic adjustment system to make the compression more closely fit the surface of steel wires of different thicknesses.

[0028] like Figure 4 As shown, the tensioning device 8 includes a tensioning wheel 801, and two tensioning wheels 801 are provided. A sliding groove is opened at the two side shafts of the upper tensioning wheel 801, and the two ends of the shaft of the upper tensioning wheel 801 are fixedly connected to the moving block 802. The top of the moving block 802 is fixedly connected to the spring 803, and the sliding groove of the spring 803 drives the moving block 802 to move and adjust inside the sliding groove.

[0029] In the above solution, the spring 803 and the moving block 802 form an elastic adjustment system, which can adapt to steel wire ropes of different diameters and increase working diversity.

[0030] like Figure 1-4As shown, the equipment is moved to the working area, one end of the wire rope is pulled out through the tensioning device 8 at the front end of the machine body 1, and then tied to the transportation tool, and the motor 5 is started to realize the rope release work. When recycling, the motor 5 needs to be reversed, and the wire rope passes through the tensioning wheel 801 of the tensioning device 8, and a tension is applied to the wire rope, and then it is wound on the recycling roller 3. When the wire rope is recycled, the diameter of the recycling roller 3 will slowly increase, and the steel wire will give an upward pressure to the upper pressure block 401, so that the pressure block 401 rises and squeezes the compression spring 402, because the elastic force of the compression spring 402 will in turn make the pressure block 401 Block 401 compresses the wire rope. Because the wire rope is repeatedly swung left and right for recovery when it shrinks, the diameter of each place on the recovery roller 3 is different. Because the pressing block 401 is divided into multiple groups, different diameters can be independently compressed without interfering with each other. After the recovery is completed, the recovered recovery roller 3 can be replaced to achieve multiple uses. First, the threaded rod 204 on the U-shaped block 205 is taken out, and then the top block 203 is retracted. The electric push rod 7 is started to move the support frame 6 to the left, and the recovery roller 3 is taken over by a forklift and moved out for replacement, which greatly improves the work efficiency.
