The outer wall of the wheel body is fixedly connected with a support plate. Both sides of the support plate are fixedly connected with support rods. An installation groove is arranged inside the wheel body. A limit card slot is arranged on the inner wall of the installation groove. A fixing groove is arranged on the outer wall of the support plate, and the number of the fixing grooves is set to be multiple. It is convenient for the traction ring frame to be quickly overhauled and replaced, improves the overhaul efficiency, and at the same time avoids the overall replacement of the wheel body, reduces the replacement cost, and enhances the safety and practicability.

[0005] When the above technical solution is actually implemented, by removing the retaining ring, multiple fixing grooves can be removed, and the fixing grooves can be directly replaced. However, the retaining ring is directly fixed to the traction ring frame by screws, and the installation position of the retaining ring cannot be changed according to the actual installation needs. If the size of the replaced fixing groove does not match and there is a certain gap between the installation and the retaining ring, then it will affect the normal use of the traction wheel.

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] The present utility model provides a technical solution:

[0027] Please refer to Figures 1 to 3 , a balanced elevator traction wheel structure, including a traction wheel body 1, a fixed bottom plate 2 for limiting is fixedly arranged at the bottom of the traction wheel body 1, the cross-section of the fixed bottom plate 2 and the traction wheel body 1 forms an inverted T-shaped structure, a plurality of rope grooves 3 for installing steel wire ropes are sleeved outside the traction wheel body 1, and a pressing plate 4 for pressing the rope groove 3 is arranged above the rope groove 3;

[0028] The pressing plate 4 includes a support inner ring 45 arranged inside the pressing plate 4, and support ribs 41 for fixing are arranged on the inner wall of the support inner ring 45. The end of the support rib 41 is provided with a positioning inner ring 42 that coincides with the vertical center line of the traction wheel body 1. A threaded hole 43 is opened inside the support rib 41, and a fastening screw 44 is threadedly connected inside the threaded hole 43. A plurality of rubber gaskets 5 are arranged between the support rib 41 and the traction wheel body 1;

[0029] The fastening screw 44 passes through the inside of the rubber gasket 5, and an installation hole 12 is provided at the connection between the fastening screw 44 and the traction wheel body 1. The inner diameter of the support inner ring 45 is adapted to the outer diameter of the traction wheel body 1, and the outer diameter of the pressing disc 4 is larger than the outer diameter of the rope groove 3. The thicknesses of the support ribs 41 and the positioning inner ring 42 are smaller than the thickness of the support inner ring 45, and the thickness of the support inner ring 45 is the same as the thickness of the pressing disc 4. The rubber gasket 5 is located between the support ribs 41 and the traction wheel body 1.

[0030] By adopting the above technical solution, when the rope groove 3 needs to be replaced, the fastening screw 44 on the pressing disc 4 is disassembled, so that the fastening screw 44 and the pressing disc 4 are separated from each other, and then the pressing disc 4 and the traction wheel body 1 can be separated from each other. Thus, the rope groove 3 on the traction wheel body 1 can be taken off in sequence. When the number or notch shape of the rope grooves 3 needs to be increased or decreased, a suitable rope groove 3 can be directly selected, installed on the traction wheel body 1, and the pressing disc 4 is directly sleeved outside the traction wheel body 1. At this time, the support inner ring 45 abuts against the traction wheel body 1. A suitable number of rubber gaskets 5 are placed between the support ribs 41 and the traction wheel body 1. Through holes for installing the fastening screw 44 are provided on the rubber gasket 5. Align the through holes on the rubber gasket 5 with the installation holes 12, and move the support inner ring 45 to a suitable position so that the pressing disc 4 abuts against the rope groove 3, eliminating the gap between the rope grooves 3. Since the thickness of the support ribs 41 is smaller than the thickness of the pressing disc 4, when the support ribs 41 are in close contact with the traction wheel body 1, the pressing disc 4 is completely sleeved outside the traction wheel body 1. The distance difference between the pressing disc 4 and the traction wheel body 1 can be changed by increasing the number of rubber gaskets 5, thereby avoiding the generation of gaps between the rope grooves 3.

[0031] Specifically, as Figure 4 shown, a number of positioning holes 11 for positioning are further provided around the traction wheel body 1, and a bearing 13 for installation is further installed inside the traction wheel body 1. A number of positioning blocks 31 are provided around the rope groove 3, and the external dimensions of the positioning blocks 31 are adapted to those of the positioning holes 11. The rope groove 3 is engaged with the traction wheel body 1 through the positioning blocks 31 and the positioning holes 11, and the inner diameter of the rope groove 3 is adapted to the outer diameter of the traction wheel body 1.

[0032] By adopting the above technical solution, the bearing 13 on the traction wheel body 1 is installed on the power output shaft of the traction machine, and the rope groove 3 is directly sleeved outside the positioning holes 11 through the positioning blocks 31, thereby engaging the rope groove 3. The rope groove 3 cannot rotate on the traction wheel body 1. The notch of the rope groove 3 can be selected as a circular notch or a V-shaped notch to meet the use of different types of steel wire ropes. The steel wire rope is wound outside the rope groove 3.

[0033] Working principle: When the rope groove 3 needs to be replaced, remove the fastening screw 44 on the pressing disc 4 to separate the fastening screw 44 from the pressing disc 4, so that the pressing disc 4 can be separated from the traction wheel body 1. Thus, the rope groove 3 on the traction wheel body 1 can be removed in sequence. When it is necessary to increase or decrease the number of rope grooves 3 or the shape of the groove openings, a suitable rope groove 3 can be directly selected. The rope groove 3 is directly sleeved outside the positioning hole 11 through the positioning block 31, and the pressing disc 4 is directly sleeved outside the traction wheel body 1. At this time, the support inner ring 45 abuts against the traction wheel body 1. Place an appropriate number of rubber gaskets 5 between the support ribs 41 and the traction wheel body 1, align the through holes on the rubber gaskets 5 with the mounting holes 12, and move the support inner ring 45 to a suitable position so that the pressing disc 4 abuts against the rope groove 3 to eliminate the gap between the rope grooves 3.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
