DETAILED DESCRIPTION

[0026] The technical solutions of the present application will be described clearly and completely below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0027] As shown in the drawings, Figures 1 to 3 A locking mechanism of a steel wire rope, comprising a base plate 2 and a pair of guide wheel structures 1 mounted on the inner side of the base plate 2;

[0028] Each guide wheel structure 1 comprises a mounting seat 11 connected to the inner side of the base plate 2 and a guide wheel 12 rotatably arranged in the port of the mounting seat 11;

[0029] A compression assembly 3, which comprises a hydraulic cylinder 32 fixedly installed on the middle of the outer side of the base plate 2, a compression plate 33 fixedly installed on the rod end of the hydraulic cylinder 32, a guide column 34 fixedly installed on both ends of the inner side of the compression plate 33 and respectively inserted through the base plate 2 and the mounting seat 11, and a compression block 35 arranged at the end of each guide column 34;

[0030] Specifically, the middle part of each guide wheel 12 is designed to be concave, each compression block 35 is designed to be arc-shaped, and the side end of each compression block 35 is threadedly connected to the end of the guide column 34. The arc-shaped design of the compression block 35 can fit the outer wall of the steel wire rope. The steel wire rope is placed in the concave part of the guide wheel 12 by being inserted through the ports of the pair of mounting seats 11. Then, the hydraulic cylinder 32 is activated to shrink, which in turn drives the compression plate 33 and the two guide columns 34 to move towards the guide wheel 12. This movement continues until the pair of arc-shaped compression blocks 35 tightly fit on the steel wire rope in the concave part of the guide wheel 12. Due to the arc-shaped design of the compression block 35, it can fit the outer wall of the steel wire rope, effectively achieving compression locking, thereby enhancing the safety during use;

[0031] Specifically, a buffer compression spring 31 is sleeved on each guide column 34, and the side of each buffer compression spring 31 is fixedly installed on the outer side of the base plate 2. When the hydraulic cylinder 32 shrinks and pulls the compression plate 33, the guide column 34 will compress the buffer spring 31. This buffering effect can effectively prevent potential damage to the steel wire rope caused by excessive extrusion force, ensuring that the locking operation is both effective and safe.

[0032] As Figure 2 and Figure 3 shown, the embodiment also provides another implementation, specifically as follows:

[0034] Specifically, the side surface of the base plate 2 is provided with a clamping groove 43 at the position corresponding to the mounting seat 11, and a positioning column 44 is mounted on both sides of the clamping groove 43, and an external thread is formed on the outer wall surface of each positioning column 44, and a fastener 45 is threadedly connected to each positioning column 44, and during installation, the side surface of each mounting seat 11 is clamped in the clamping groove 43, the clamping blocks 41 on both sides are sleeved on the positioning columns 44, and then the fastener 45 is screwed, so that the mounting seat 11 and the guide wheel 12 can be conveniently disassembled and assembled, so as to adapt to the guide wheel 12 and improve the applicability.

[0035] As Figures 1 to 3 shown, the embodiment also needs to be explained that the actual size and shape of each component in the application file are selected and installed according to the actual demand on site; the embodiment is installed on a specific hoist. In addition, it should be noted that the hydraulic cylinder 32 is a commercially available product of the prior art, and its working principle has been disclosed. This application file only improves the existing technology of the steel wire rope without a self-locking device, which has certain safety hazards and is prone to safety accidents. It does not involve other aspects; the working principle of the locking mechanism of the steel wire rope is introduced as follows:

[0036] When the new scheme is used, first, the entire locking mechanism is stably assembled to the equipment. Then, the steel wire rope is respectively threaded through the ports of a pair of mounting seats 11 and placed in the inner recessed part of the guide wheel 12. Subsequently, the hydraulic cylinder 32 is activated to shrink, which in turn drives the pressing plate 33 and the two guide columns 34 to move towards the guide wheel 12. This movement process continues until the pair of arc-shaped pressing blocks 35 tightly fit on the steel wire rope in the inner recessed part of the guide wheel 12. Due to the arc-shaped design of the pressing blocks 35, the outer wall of the steel wire rope can be fitted, realizing effective pressing and locking, thereby enhancing the safety guarantee during use.

[0037] In addition, a buffer spring 31 is designed. When the hydraulic cylinder 32 is retracted and pulls the pressing plate 33, the guide column 34 will compress the buffer spring 31. This buffering effect can effectively prevent potential damage to the steel wire rope due to excessive extrusion force, ensuring that the locking operation is both effective and safe. In addition, during installation, by clamping the side of each mounting seat 11 in the clamping groove 43, the clamping block 41 on both sides is sleeved on the positioning column 44, and the fastener 45 is tightened, the convenient disassembly and assembly of the mounting seat 11 and the guide wheel 12 can be conveniently realized, so as to adapt the guide wheel 12 and improve the applicability.

[0038] The above examples are only used to illustrate the technical method of the utility model and are not limited. Although the utility model has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical method of the utility model can be modified or replaced equivalently without departing from the spirit and scope of the technical method of the utility model.
