Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0022] Reference Figures 1-4 , the utility model provides an embodiment: winch with protection mechanism, including support mechanism 1 and winch mechanism 2, support mechanism 1 includes winch platform 101, and the trapezoidal sliding groove 102 is set up in winch platform 101 upper end face one side center, and winch platform 101 upper end face other side is fixedly set with output motor 104, and the output end of output motor 104 is fixedly set with first gear 105;

[0023] Winch mechanism 2 includes first support plate 201 and second support plate 204, and first support plate 201 and second support plate 204 are respectively rotationally sleeved with first winch cylinder 202 and second winch cylinder 203, and the lower end surface center of first support plate 201 and second support plate 204 is respectively fixedly set with second trapezoidal sliding block 210 and first trapezoidal sliding block 208, and the end of first winch cylinder 202 away from second support plate 204 is fixedly set with second gear 211, and the inside of first trapezoidal sliding block 208 is threadedly sleeved with threaded rod 209.

[0024] The lower end surface of the winding platform 101 is fixedly provided with support legs 103 on both sides, and a gap is formed in the center of the front side of the winding platform 101. The first winding drum 202 and the second winding drum 203 are designed to be spliced. The first gear 105 and the second gear 211 are connected in meshing. One end of the threaded rod 209 is rotatably provided with the second trapezoidal slider 210, and the other end of the threaded rod 209 is fixedly provided with the hand wheel 207. The second trapezoidal slider 210 and the first trapezoidal slider 208 are slidably arranged in the trapezoidal sliding groove 102. Two insertion holes 205 are formed in the side of the second support plate 204 close to the front end, and the two insertion holes 205 are movably sleeved with limiting rods 206, and one end of the two limiting rods 206 is fixedly provided with the first support plate 201.

[0025] Specifically, the support mechanism 1 includes a winding platform 101 and support legs 103. The winding platform 101 is provided with a trapezoidal sliding groove 102 for cooperating with a first trapezoidal sliding block 208 and a second trapezoidal sliding block 210 of the winding mechanism 2. This slidable design allows the support mechanism 1 and the winding mechanism 2 to be independently disassembled and installed, facilitating maintenance and transportation. The winding mechanism 2 is composed of a first support plate 201 and a second support plate 204, which are respectively sleeved with a first winding drum 202 and a second winding drum 203. The two winding drums can be adjusted in length according to demand through splicing design, adapting to different load and height requirements. Through modular design, the support mechanism 1 and the winding mechanism 2 can be independently disassembled and installed, solving the problem of inconvenient maintenance and transportation of the traditional winding machine, reducing maintenance and transportation costs, and improving the flexibility of the equipment. In the winding mechanism 2, two insertion holes 205 are provided on the second support plate 204, and a limiting rod 206 is movably sleeved inside. One end of the limiting rod 206 is fixed on the first support plate 201, which can prevent the steel wire rope from deflecting or knotting during work. Through the protection design of the limiting rod 206, the steel wire rope is guided and limited during lifting, avoiding deflection and damage, improving the safety of operation and the stability of the equipment. The first trapezoidal sliding block 208 and the second trapezoidal sliding block 210 in the winding mechanism 2 are respectively slidably arranged in the trapezoidal sliding groove 102. By rotating the hand wheel 207, the threaded rod 209 is rotated, thereby adjusting the position of the first trapezoidal sliding block 208 and the second trapezoidal sliding block 210 in the trapezoidal sliding groove 102, realizing the adjustment of the winding drum length (i.e. the splicing length of the first winding drum 202 and the second winding drum 203). Users can easily adjust the winding drum length through the hand wheel 207 according to different load and height requirements, avoiding the problem of limited applicability caused by the fixed size of the winding drum of the traditional winding machine. This not only reduces the user's demand for multiple specifications of winding machines, but also significantly improves the multi-scene applicability of the equipment. The output motor 104 drives the first winding drum 202 and the second winding drum 203 to rotate through the meshing transmission of the first gear 105 and the second gear 211, realizing the winding and unwinding of the steel wire rope. This gear transmission design ensures the efficient operation of the winding machine. Through the transmission of the motor and the gear, the working efficiency of the winding machine is improved, and the structure is simple and reliable, facilitating maintenance and operation. Through the detachable design, the maintenance and transportation costs are reduced; through the adjustable winding drum length design, the user's procurement demand for multiple specifications of winding machines is reduced, further reducing the management cost. The design of the protection mechanism and the adjustable winding drum length makes the operation of the winding machine more convenient in different application scenarios, significantly improving the working efficiency.

[0026] Working principle: in use, start the output motor 104, the output end of the output motor 104 rotates and drives the first gear 105 to rotate, the first gear 105 rotates and drives the second gear 211 to rotate, the second gear 211 rotates and drives the first winding drum 202 to rotate, the first winding drum 202 rotates and drives the second winding drum 203 to rotate, realizing the winding and unwinding of the steel wire rope on the winding drum, in this process, the steel wire rope is threaded between the two limiting rods 206, realizing the protection of the steel wire rope and preventing the steel wire rope from being pulled skew;

[0027] Secondly, rotate the hand wheel 207, the hand wheel 207 rotates and drives the threaded rod 209 to rotate, the threaded rod 209 rotates and drives the first trapezoidal slider 208 to slide in the trapezoidal sliding groove 102, thereby adjusting the left and right positions of the second winding drum 203, realizing the length of splicing with the first winding drum 202, and making the winding drum curl the corresponding steel wire rope;

[0028] Furthermore, the support mechanism 1 and the winding mechanism 2 are independently designed, and are spliced by the first trapezoidal slider 208 and the second trapezoidal slider 210 sliding in the trapezoidal sliding groove 102, which is convenient for disassembly and installation.

[0029] Finally, it should be pointed out that: the above only for the preferred embodiments of the utility model, and does not limit the utility model, although the utility model is described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to part of technical features, any modification, equivalent replacement, improvement etc. made within the spirit and principles of the utility model, should be included in the protection scope of the utility model.
