Abstract
Description
Technical Field
[0001] This utility model relates to the field of rubber products technology, and in particular to a cableway wheel liner. Background Technology
[0002] In cableway systems for infrastructure such as railways and mines, the wheel liner currently used for transporting goods is typically made of metal steel, which has significant drawbacks: metal wheel liner easily wears down the traction rope, and prolonged use may lead to rope breakage, seriously affecting the operational safety of the cableway. With continuous advancements in materials technology, it is now possible to use polymer materials to replace metal materials. Therefore, this solution designs a wheel liner with a rubber-metal composite structure to improve equipment durability and operational safety. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a cableway wheel liner that combines rubber and metal structures. The rubber is used to support the traction rope, reducing wear on the traction rope; the rubber is detachable and easy to replace, thus enabling the wheel liner to be reused repeatedly.
[0004] In order to achieve the purpose of this utility model, the following solution is proposed:
[0005] A cableway wheel liner includes a hub, two retaining rings, two sealing rings, a rubber wheel, and bearing components.
[0006] The wheel hub has two rings of threaded holes on both sides, and a through hole is provided in the center of the wheel hub;
[0007] The rubber wheel includes an integrally formed base ring and two wing rings. The wing rings are trumpet-shaped and the two wing rings are symmetrically arranged on the top and bottom surfaces of the base ring. The side of the wing ring with the smaller inner diameter is connected to the outer right angle of the base ring. The inner and outer walls of the wing rings are both set as arc surfaces. The base ring is fitted onto the outer wall of the hub, and the outer wall of the base ring is provided with an arc groove.
[0008] Two retaining rings and two sealing rings are symmetrically arranged on both sides of the hub, and the sealing rings are located within the range of the corresponding retaining rings. The retaining rings are fixedly connected to the threaded holes of the outer ring of the hub by multiple bolts. The retaining rings are used to restrict the inner walls of the base ring and the wing ring. The sealing rings are fixedly connected to the threaded holes of the inner ring of the hub by multiple bolts. The sealing rings are used to restrict the bearing components within the through hole.
[0009] Furthermore, both sides of the wheel hub are provided with annular grooves, which are located between two threaded holes.
[0010] Furthermore, the top surface of the wheel hub is higher than the top surface of the base ring.
[0011] Furthermore, the outer distance between the two retaining rings is less than the thickness of the rubber wheel.
[0012] Furthermore, the bearing component includes two bearings, a pin, and a sleeve. The sleeve is fitted onto the pin, and both bearings are fitted onto the sleeve. A raised ring is provided on the outer wall of the sleeve, which is located between the two bearings. The inner wall of the sealing ring is tightly attached to the outer wall of the sleeve.
[0013] The beneficial effects of this invention are as follows: by having the rubber wheel contact and function with the traction rope, and through the buffering and protective effect of the rubber wheel, wear on the traction rope can be reduced, ensuring the safe and stable operation of the cableway. When the rubber wheel is worn out, the bolts of the retaining ring can be loosened, the rubber wheel removed, and a new rubber wheel replaced; the wheel liner can then be reused repeatedly. Attached Figure Description
[0014] Figure 1 A schematic diagram of the overall structure of the cableway wheel liner is shown.
[0015] Figure 2 An exploded view of the cableway wheel liner is shown;
[0016] Figure 3 A longitudinal sectional view of the cableway wheel liner is shown. Detailed Implementation
[0017] like Figure 1 As shown, this embodiment provides a cableway wheel bushing, including a hub 1, two retaining rings 2, two sealing rings 3, a rubber wheel 4, and a bearing component 5.
[0018] Specifically, such as Figure 2 As shown, the top and bottom surfaces of the hub 1 each have two rings of threaded holes, which are referred to as the outer ring threaded hole and the inner ring threaded hole, respectively, for ease of description. Both the top and bottom surfaces of the hub 1 have annular grooves 12 located between the two rings of threaded holes. The hub 1 has a through hole 11 at its center, extending vertically through the entire hub.
[0019] Specifically, such as Figure 2 , Figure 3 As shown, the rubber wheel 4 includes an integrally formed base ring 41 and two wing rings 42. The base ring 41 is tightly fitted onto the outer wall of the hub 1, and the base ring 41 exerts an internal clamping force on the hub 1. The top surface of the hub 1 is higher than the top surface of the base ring 41, and the bottom surface of the hub 1 is lower than the bottom surface of the base ring 41. The outer wall of the base ring 41 is provided with an arc-shaped groove 411, which is used to support the traction rope of the cableway system. The wing rings 42 are trumpet-shaped, and the two wing rings 42 are symmetrically arranged on the top and bottom surfaces of the base ring 41. Figure 3 As can be seen, the side with the smaller inner diameter of the wing ring 42 is connected to the outer right angle of the base ring 41. The inner wall of the wing ring 42 is set as a first arc surface, and its outer wall is set as a second arc surface. The inner diameter of the second arc surface is larger than that of the arc groove 411.
[0020] Specifically, such as Figure 3As shown, two retaining rings 2 are symmetrically arranged on the top and bottom surfaces of the hub 1. A ring of through holes is arranged on the retaining ring 2, and it is fixed to the threaded holes on the outer ring of the hub 1 by multiple bolts. Taking the retaining ring 2 located on the top surface of the hub 1 as an example, the bottom surface of the retaining ring 2 is in close contact with both the top surface of the hub 1 and the top surface of the base ring 41. The outer wall of the retaining ring 2 is set as a third arc surface, which is in close contact with the first arc surface of the wing ring 42. The retaining ring 2 has two functions: first, to prevent the base ring 41 from detaching from the hub 1; and second, to support the inner wall of the wing ring 42 and prevent the wing ring 42 from deforming and collapsing.
[0021] from Figure 3 As can be seen from this, the outer distance between the two retaining rings 2 is less than the thickness of the rubber wheel 4. The outer distance between the two retaining rings 2 refers to the maximum length of the distance between the two retaining rings 2, and the thickness of the rubber wheel 4 refers to the outer distance between the two wing rings 42.
[0022] When the cableway system is running, the retaining ring 2 provides sufficient support to the rubber wheel 4, preventing the cableway's traction rope from detaching from the rubber wheel 4. Normally, the traction rope is located within the arc-shaped groove 411. When the wind is too strong, causing the traction rope to swing excessively, it may extend beyond the arc-shaped groove 411 and move into the range of the wing ring 42. Therefore, the function of the wing ring 42 is to accommodate the traction rope and limit its swing amplitude, thus improving safety. When the wind is weak, the traction rope can automatically return to the arc-shaped groove 411, and the wing ring 42 will not obstruct its return.
[0023] Specifically, such as Figure 3 As shown, two sealing rings 3 are symmetrically arranged on the top and bottom surfaces of the hub 1, and the sealing rings 3 are located within the range of the corresponding retaining rings 2. A ring of through holes is arranged on the sealing ring 3, and it is fixedly connected to the threaded hole of the inner ring of the hub 1 by multiple bolts. The function of the sealing ring 3 is to restrict the bearing component 5 within the through hole 11.
[0024] More specifically, such as Figure 2 , Figure 3 As shown, the bearing component 5 includes two bearings 51, a shaft pin 52, and a sleeve 53. The sleeve 53 is fitted onto the shaft pin 52, and both bearings 51 are fitted onto the sleeve 53. A raised ring 531 is provided on the outer wall of the sleeve 53. The raised ring 531 is located between the two bearings 51. The inner wall of the sealing ring 3 is tightly attached to the outer wall of the sleeve 53. Taking the sealing ring 3 located on the top surface of the hub 1 as an example, the bottom surface of the sealing ring 3 is simultaneously tightly attached to the top surface of the hub 1 and the top surface of the corresponding bearing 51. The top surface of the sealing ring 3 is flush with the top surface of the sleeve 53.
[0025] In summary, this solution utilizes the contact between the rubber wheel 4 and the traction rope to achieve its function. The buffering and protective properties of the rubber wheel 4 reduce wear on the traction rope, ensuring the safe and stable operation of the cableway. When the rubber wheel 4 wears out, the bolts on the retaining ring 2 are loosened, the rubber wheel 4 is removed, and a new rubber wheel 4 is installed; the wheel liner can then be reused repeatedly.
[0026] The above embodiments are only used to illustrate the technical concept and features of this utility model, and are not intended to be unique or to limit this utility model. Those skilled in the art should understand that various changes or equivalent substitutions made to this utility model without departing from its scope are all within the protection scope of this utility model.
