DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Example 1: Reference Figure 1-3 A wire rope guide device includes a first connecting plate 1, to which two support blocks 2 are fixedly connected, and the two support blocks 2 are rotatably connected to support shafts 3 through bearings. Both ends of the support shaft 3 are connected to abutment rings 7 through a connecting mechanism, and the two abutment rings 7 are adjusted by an adjusting mechanism. The adjusting mechanism includes a connecting bearing 9, and the connecting bearing 9 is a slewing bearing. The slewing bearing is designed to carry an axial force load. When the wire rope moves, a force is applied to the abutment ring 7, causing the connecting bearing 9 to be subjected to an axial force.

[0019] The inner axial surface of the connecting bearing 9 is fixedly connected to the abutment ring 7, and a hinged rod 13 is hinged on the outer bearing surface of the connecting bearing 9. The hinged rod 13 is adjusted by a moving mechanism. By adjusting the inclination angle of the two hinged rods 13, the abutment ring 7 is driven to move on the support shaft 3, so that the abutment ring 7 can abut and limit steel wire ropes of different diameters, so as to guide steel wire ropes of different diameters, thereby improving the applicability of the device.

[0020] The connecting mechanism includes a limit groove 16, which is opened on the support shaft 3. A limit block 8 is fixedly connected to the abutment ring 7, and the limit block 8 can be slidably set in the limit groove 16. By adopting the design of the limit block 8 and the limit groove 16, the abutment ring 7 can rotate together with the support shaft 3 when it is sleeved on the support shaft 3.

[0021] The moving mechanism includes a threaded column 12, which is rotatably connected to the support block 2 through a bearing. A threaded sleeve 15 is threadedly connected to the threaded column 12, and a hinged rod 13 is hinged on the threaded sleeve 15. By rotating the threaded column 12, the position of the threaded sleeve 15 on the threaded column 12 is adjusted, thereby driving one end of the hinged rod 13 to move and adjust the inclination.

[0022] Embodiment 2: In embodiment 1, when in use, the threaded column 12 is prone to rotate, causing the abutment ring 7 to move. Figure 1-3 As another preferred embodiment of the utility model, on the basis of embodiment 1, a rotating part 14 is fixedly connected to the threaded column 12, and a plurality of fixing holes 11 are equidistantly provided on the circumference of the rotating part 14, in which a fixing column 10 can be inserted, and the fixing column 10 is limited by a limiting mechanism. By inserting the fixing column 10 into the fixing hole 11, the threaded column 12 will be limited to prevent the threaded column 12 from rotating during use.

[0023] The limiting mechanism includes a second connecting plate 6, which abuts against the first connecting plate 1, and is fixedly connected to a fixing column 10. A spring 4 is fixedly connected between the second connecting plate 6 and the supporting block 2. A limiting rod 5 is fixedly connected to the second connecting plate 6, and the limiting rod 5 passes through the supporting block 2. The limiting rod 5 is used to limit the second connecting plate 6. When the fixing column 10 needs to be pulled out, the spring 4 is stretched by pulling the second connecting plate 6, so that the fixing column 10 is pulled out of the fixing hole 11, thereby releasing the limitation on the threaded column 12.

[0024] When in use, by pulling the second connecting plate 6, the spring 4 is stretched, thereby pulling the fixing column 10 out of the fixing hole 11, releasing the limit on the threaded column 12, rotating the threaded column 12, and adjusting the position of the threaded sleeve 15 on the threaded column 12, thereby driving one end of the hinged rod 13 to move, adjusting the inclination, and driving the abutment ring 7 to move on the support shaft 3, and adjusting the distance between the two abutment rings 7.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
