Two sets of lifting frames covering the corresponding free ends of the cover are also provided on the base. A worm and two sets of worm gears are provided inside the cover, with the worm meshing with the two sets of worm gears. The lifting frame contains the threaded rod and the slider. The threaded rod passes through the cover and is connected to the center of the worm gear. The output end of the first motor passes through the cover and is connected to the worm gear. The slider is threadedly connected to the threaded rod. The front of the slider protrudes from the lifting frame and is connected to the sliding frame. The lifting ring assembly includes a lifting ring body, an adjusting block, a second motor, and a threaded rod. The sliding frame contains the threaded rod and two sets of symmetrically arranged adjusting blocks. The lifting ring body is located below the adjusting blocks. The output end of the second motor passes through the sliding frame and is connected to the threaded rod.

[0007] To facilitate the movement and fixation of the equipment, the present invention is improved in that the moving component includes casters and brakes, the casters are provided at the four corners below the base, and the brakes are provided around the casters.

[0008] To ensure the strength of the lifting frame, this utility model is improved by providing reinforcing ribs on the base that are connected to the lifting frame.

[0010] Preferably, the upper part of the lifting ring is connected to the adjusting block by bolts.

[0011] Preferably, the base is also provided with a handrail.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides a lifting ring device for hoist maintenance, which has the following beneficial effects:

[0014] This lifting ring device for hoist maintenance uses a lifting assembly where a first motor drives a worm gear to rotate. The worm gear meshes with a worm wheel, which in turn drives a threaded rod to rotate. Because the slider is threadedly connected to the threaded rod, the rotation of the threaded rod causes the slider to move up and down within the lifting frame, thereby adjusting the height of the sliding frame and the lifting ring assembly.

[0015] In the lifting ring assembly, a second motor drives a forward and reverse threaded screw to rotate. Since the forward and reverse threaded screws are threadedly connected to two sets of adjusting blocks, and the adjusting blocks are symmetrically arranged, the rotation of the screws causes the two sets of adjusting blocks to move towards or away from each other, thereby adjusting the distance between the lifting ring bodies. This design allows for flexible adjustment of the distance between the lifting rings according to different sizes of hoist components, better adapting to lifting needs and improving the versatility of the lifting ring device.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 A lifting ring device for hoist maintenance includes a support assembly, a lifting assembly, and a lifting ring assembly. The support assembly includes a base 1 and a moving assembly. The moving assembly is located at the four corners of the base 1. The lifting assembly includes a cover 2, a first motor 3, a worm gear 4, a worm 5, a threaded rod 6, a lifting frame 7, a slider 8, and a sliding frame 9. The cover 2 is fixed to the base 1 in a U-shape. The base 1 also has two sets of lifting frames 7 covering the free ends of the corresponding covers 2. The worm 5 and two sets of worm gears 4 are disposed inside the cover 2. The worm 5 meshes with the two sets of worm gears 4. The threaded rod 6 and the slider 8 are disposed inside the lifting frame 7. The threaded rod 6 passes through the cover 2 and is connected to the center of the worm gear 4. The output end of the first motor 3 passes through the cover 2 and is connected to the worm gear 5. The slider 8 is threadedly connected to the threaded rod 6. The front of the slider 8 protrudes from the lifting frame 7 and is connected to the sliding frame 9. The lifting ring assembly includes a lifting ring body 10, an adjusting block 16, a second motor 11, and a positive and negative threaded screw 12. The positive and negative threaded screw 12 and two sets of symmetrically arranged adjusting blocks 16 are arranged inside the sliding frame 9. The lifting ring body 10 is arranged below the adjusting block 16. The output end of the second motor 11 passes through the sliding frame 9 and is connected to the positive and negative threaded screw 12.

[0023] Base 1: As the basic support component of the entire lifting ring assembly, it bears the weight of the lifting assembly and the lifting ring assembly, as well as the load from the lifted components during lifting operations. It provides a stable mounting platform for other components;

[0024] The casters 13 located at the four corners of the base 1 allow the lifting ring device to move freely in the horizontal direction. Since the casters 13 can rotate 360 ​​degrees, operators can easily push the lifting ring device to different positions on the hoist to accommodate the lifting needs of different components.

[0025] Brakes 14 installed around the casters 13 are used to secure the lifting ring device when needed. When lifting operations begin or when the lifting ring device needs to be stopped in a specific position, the operator can operate the brakes 14 to stop the casters 13 from rotating, thereby securing the lifting ring device firmly to the ground, preventing it from moving during lifting, and ensuring operational safety.

[0026] The first motor 3, serving as the power source for the lifting assembly, is a servo motor capable of precisely controlling its speed and direction of rotation. When the height of the lifting ring assembly needs to be adjusted, the first motor 3 is activated. Its output end passes through the cover 2 and connects to the worm gear 5, driving the worm gear 5 to rotate. The worm gear 5 inside the cover 2 meshes with two sets of worm wheels 4, and the rotation of the worm gear 5 drives the two sets of worm wheels 4 to rotate synchronously. The center of the worm wheel 4 is connected to the threaded rod 6, so the rotation of the worm wheel 4 drives the threaded rod 6 to rotate. The slider 8 inside the lifting frame 7 is threadedly connected to the threaded rod 6. According to the principle of threaded transmission, when the threaded rod 6 rotates, the slider 8 moves up and down along the axial direction of the threaded rod 6 within the lifting frame 7. Since the front of the slider 8 protrudes from the lifting frame 7 and connects to the sliding frame 9, the up and down movement of the slider 8 drives the sliding frame 9 and the lifting ring assembly mounted on the sliding frame 9 to rise and fall synchronously, thereby achieving precise adjustment of the height of the lifting ring assembly.

[0027] The second motor 11, also a servo motor, provides power for adjusting the spacing between the lifting ring bodies 10. When the lifting ring spacing needs to be adjusted, the second motor 11 is started. Its output end passes through the slide frame 9 and connects to the threaded screw 12, driving the threaded screw 12 to rotate. The threaded screw 12 inside the slide frame 9 is threadedly connected to two sets of symmetrically arranged adjusting blocks 16, and the two ends of the threaded screw 12 have opposite thread directions (i.e., forward and reverse threads). When the threaded screw 12 rotates, according to the thread transmission principle, the two sets of adjusting blocks 16 will move towards or away from each other according to the rotation direction of the screw. The lifting ring bodies 10 are connected to the lower part of the adjusting blocks 16 by bolts, so the movement of the adjusting blocks 16 will drive the lifting ring bodies 10 to move, thereby realizing the adjustment of the spacing between the lifting ring bodies 10. In this way, the distance between the lifting rings can be flexibly adjusted according to the different sizes of hoist components to better adapt to hoisting requirements.

[0028] The reinforcing rib 15, which is connected to the lifting frame 7 on the base 1, mainly serves to enhance the strength and stability of the lifting frame 7. During the operation of the lifting assembly, the lifting frame 7 is subjected to forces from the threaded rod 6 and the slider 8. The reinforcing rib 15 can disperse these forces, preventing the lifting frame 7 from deforming or being damaged, and ensuring the normal operation of the lifting assembly.

[0029] The handrail on the base 1 provides a convenient grip for the operator. When moving the lifting ring device, the operator can hold the handrail to push the device more easily, improving the convenience and comfort of operation.
