Description

Technical Field

[0001] This application relates to the field of wire rope lifting equipment technology, specifically a lifting equipment for wire rope pulling and winding. Background Technology

[0002] A wire rope pulling and reeling device is a piece of equipment used for pulling, reeling in, and tensioning wire ropes. Its main function is to facilitate the pulling in and reeling in wire ropes, ensuring safe and effective control of the tension and position of the wire ropes during use.

[0003] Wire rope lifting devices typically use hooks to contact the wire rope and change its tension. A search of utility model publication CN211769774U reveals a wire rope pulling device comprising a fixed plate, a first mounting plate, and a second mounting plate. The fixed plate has a concave shape and multiple bolt through holes. Both the first and second mounting plates have bolt holes corresponding to these through holes. The upper ends of the first and second mounting plates are inserted into the groove of the fixed plate. The first and second mounting plates are fixedly connected to the fixed plate by locking bolts. A first hook is welded to the lower end of the first mounting plate, and a second hook is welded to the lower end of the second mounting plate. This utility model features a novel structural design and good structural stability, improving the stability of wire rope pulling and lifting. Furthermore, the mounting plates are easy to disassemble and replace, facilitating hook maintenance.

[0004] The aforementioned patent application provides a lifting device for assisting in wire rope pulling. However, this lifting device provides space for the wire to pass through by using wire pulling grooves. Because a large number of wire pulling grooves are opened to control the position of the wire rope, the strength of the lifting ring structure with the wire pulling grooves is reduced, and it is also not convenient to adjust. In view of this, a lifting device for wire rope pulling and reeling is proposed to solve the above-mentioned problems. Utility Model Content

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] Please see Figures 1 to 4 The wire rope pulling and winding hoist in this embodiment includes a mounting frame and a lifting roller 6 located on the mounting frame. The mounting frame includes two upright plates 1 and a connecting rod 2 fixedly connected between the two upright plates 1. A connecting seat 3 is also fixedly installed on the upright plate 1, and the mounting frame can be easily fixedly installed through the connecting seat 3.

[0025] In this embodiment, a rotating shaft 4 is rotatably mounted on a vertical plate 1, and a hanging roller 6 is slidably mounted on the outside of the rotating shaft 4. Specifically, the surface of the hanging roller 6 has a wire drawing groove 11 for guiding the wire rope.

[0026] It should be noted that the shaft of the hanging roller 6 has a through-hole 9 for the rotating shaft 4 to pass through. The inner wall of the through-hole 9 has a keyway protruding outward. The rotating shaft 4 has a limit key protruding on the outer wall inside the hanging roller 6. By setting the through-hole 9, the relative rotation of the hanging roller 6 and the rotating shaft 4 can be restricted, and the rotating shaft 4 can drive the hanging roller 6 to rotate.

[0027] In this embodiment, a base plate 5 is rotatably mounted on the inner wall of the upright plate 1. One end of the rotating shaft 4 is fixedly connected to the base plate 5, and a spring 7 is provided between the base plate 5 and the hanging roller 6.

[0028] Preferably, a spring seat 10 is fixedly installed on one end of the hanging roller 6, one end of the spring 7 is fixedly connected to the spring seat 10, and the other end is fixedly connected to the chassis 5. The spring seat 10 can push the hanging roller 6 to slide toward the other end of the rotating shaft 4.

[0029] In this embodiment, a protrusion 8 is fixedly installed on the end of the hanging roller 6 away from the spring seat 10. A disc 13 is hinged to the inner wall of the upright plate 1 through a hinge seat 12. The protrusion 8 abuts against the disc 13. Under the push of the spring force of the spring 7, the protrusion 8 can rotate in contact with the disc 13.

[0030] It should be noted that a threaded rod 15 is also threadedly installed on the upright plate 1. One end of the threaded rod 15 abuts against the disc 13. The threaded rod 15 is designed so that it can lift the disc 13 under rotational propulsion, causing the disc 13 to swing and tilt around the hinge seat 12.

[0031] Furthermore, the center of the disc 13 is provided with a through hole 14 for the rotating shaft 4 to pass through. The diameter of the through hole 14 is larger than the diameter of the rotating shaft 4, so that the disc 13 can provide sufficient room for movement when it swings and tilts.

[0032] In order to change the position of the protrusion 8, a first gear 16 is rotatably installed on the outside of the upright plate 1 in this embodiment. The first gear 16 is fixedly connected to the chassis 5, and the chassis 5 can be rotated by rotating the first gear 16.

[0033] In this embodiment, a second gear 17 is rotatably mounted on the outside of the upright plate 1. The teeth of the second gear 17 mesh with the first gear 16, and the position of the first gear 16 can be changed by rotating the second gear 17.

[0034] It should be noted that an electric push rod 19 is also fixedly installed on the surface of the upright plate 1. A rack 18 corresponding to the second gear 17 is fixedly installed on the power end of the electric push rod 19. By pushing the rack 18 through the electric push rod 19, the rotation of the second gear 17 can be locked.

[0035] The working principle of the above embodiments is as follows:

[0036] By rotating the threaded rod 15 on one side of the upright plate 1, the threaded rod 15 extends relative to the upright plate 1 under rotation. At this time, the threaded rod 15 pushes the disc 13 to swing relative to the hinge seat 12 and tilt. Under the elastic force of the spring 7, the hanging roller 6 contacts the disc 13 through the protrusion 8 at its end. At this time, the hanging roller 6 slides relative to the rotating shaft 4 and changes its horizontal position. When the hanging roller 6 needs to be adjusted again, it is only necessary to drive the second gear 17 to rotate through the drive source, such as a motor. When the second gear 17 meshes with the first gear 16, it causes the first gear 16 to rotate and drive the chassis 5 to rotate. At this time, the rotating shaft 4 and the hanging roller 6, which are fixedly connected to the chassis 5, rotate, changing the contact position between the protrusion 8 and the disc 13, so that the horizontal displacement of the hanging roller 6 is adjusted.
