Description

Technical Field

[0001] This utility model relates to the field of rubber-tired vehicle technology, specifically to an anti-skid rubber wheel. Background Technology

[0002] Coal mine product transport vehicles typically use rubber-tired wheels for high-speed operation. However, the conditions on the floor of coal mines are generally harsh, often with gravel, coal, or muddy surfaces. These conditions cause significant drawbacks to rubber-tired wheels, frequently resulting in slippage or even immobility. Therefore, rubber-tired wheels need to have anti-slip properties. On better-condition surfaces, the rubber-tired wheels must also not cause significant damage to the ground.

[0003] Chinese invention patent CN95107804.6 discloses an anti-skid device for rubber-tired motor vehicles. Its technical features include: a specially designed tire with a set of key pins; and a pneumatic and electronic control device on the wheel, operated from the driver's cab to raise and lower the key pins. When the key pins extend, they engage on icy or snowy surfaces to slow the vehicle. When the key pins retract, they are concealed within the tire tread, causing no damage to surfaces without ice or snow, or to the tire itself. However, the key pin and pneumatic device structures are relatively complex. Each key pin head requires a pneumatic rubber box to push it out, and retraction requires depressurization of the pneumatic rubber box followed by wheel pressure and a return spring, making it impractical. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an anti-slip rubber wheel. This invention has a simple structure and strong practicality, and can provide anti-slip properties on rough roads while avoiding damage to roads in good working conditions.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an anti-slip rubber wheel, comprising a rubber wheel body, an inner ring of the rubber wheel body having an annular cavity, and an elastic steel support ring with a notch that can be opened or closed is installed concentrically within the annular cavity. The rubber wheel body has a plurality of radial through holes spaced apart along the circumference. The elastic steel support ring has a plurality of anti-slip spikes fixedly arranged along the circumference, each corresponding to one of the radial through holes. Each anti-slip spike is inserted into one of the radial through holes. When the elastic steel support ring is opened, it can drive the anti-slip spikes to extend outward from the radial through holes. When the elastic steel support ring is closed, it can drive the anti-slip spikes to retract inward into the radial through holes. The notch ends of the elastic steel support ring are connected to a expansion and contraction mechanism for opening or closing the elastic steel support ring.

[0006] Beneficial effects: The inner ring of the rubber wheel body has an annular cavity, within which an elastic steel support ring is installed. Anti-slip spikes are mounted on the elastic steel support ring. Radial through holes are formed on the rubber wheel body corresponding to the positions of the anti-slip spikes. The anti-slip spikes penetrate these radial through holes. A contraction mechanism expands or contracts the elastic steel support ring, allowing it to extend or retract the anti-slip spikes into the radial through holes. Compared to existing technologies, this design is simpler and more practical. On rough surfaces, expanding the elastic steel support ring extends the anti-slip spikes, providing anti-slip protection. On smoother surfaces, contracting the elastic steel support ring retracts the anti-slip spikes, preventing damage to the surface and offering greater flexibility in use.

[0007] Based on the above, the expansion mechanism includes a hydraulic cylinder, with both ends of the hydraulic cylinder hinged to the two ends of the notch in the elastic steel support ring.

[0008] Beneficial effects: The elastic steel support ring can be expanded or contracted by extending and retracting the hydraulic cylinder. The structure is simple and the operation is reliable.

[0009] Based on the above, the expansion mechanism includes an electric cylinder, with both ends of the electric cylinder hinged to the two ends of the notch in the elastic steel support ring.

[0010] Beneficial effects: Electric cylinders and hydraulic cylinders have the same function.

[0011] Based on the above, the expansion mechanism includes a cylinder, with both ends of the cylinder hinged to the two ends of the notch in the elastic steel support ring.

[0012] Beneficial effects: The cylinder and the hydraulic cylinder have the same function.

[0013] This utility model has substantial features and progress compared with the prior art. Specifically, this utility model has a simple structure. By simply expanding or contracting the elastic steel support ring, the anti-slip spikes can be extended or retracted, so that the rubber wheel can play an anti-slip role on rough roads, while avoiding damage to roads with good working conditions. It is highly practical. Attached Figure Description

[0015] In the diagram: 1. Rubber wheel body; 2. Ring cavity; 3. Elastic steel support ring; 4. Radial through hole; 5. Anti-slip spike; 6. Hydraulic cylinder. Detailed Implementation

[0016] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0017] Example 1 like Figure 1As shown, an anti-slip rubber wheel includes a wheel body 1. The inner ring of the wheel body 1 has an annular cavity 2. An elastic steel support ring 3 with a notch and capable of being expanded or contracted is installed concentrically within the annular cavity 2. The wheel body 1 has a plurality of radial through holes 4 spaced apart along its circumference. The elastic steel support ring 3 has a plurality of anti-slip spikes 5 fixedly arranged along its circumference, each corresponding to one of the radial through holes 4. Each anti-slip spike 5 is inserted into one of the radial through holes 4. When the elastic steel support ring 3 is expanded, it can drive the anti-slip spikes 5 to extend outward from the radial through holes 4. When the elastic steel support ring 3 is contracted, it can drive the anti-slip spikes 5 to retract inward into the radial through holes 4. The two ends of the notch of the elastic steel support ring 3 are connected to a expansion and contraction mechanism for expanding or contracting the elastic steel support ring 3.

[0018] Furthermore, the expansion mechanism includes a hydraulic cylinder 6, with both ends of the hydraulic cylinder 6 hinged to the two ends of the notch in the elastic steel support ring 3.

[0019] The power and control of cylinder 6 are derived from the vehicle.

[0020] When this invention is in operation: when the vehicle is traveling on a rough road surface, the control cylinder 6 extends, thereby opening the elastic steel support ring 3. The elastic steel support ring 3 causes the anti-slip spikes 5 to extend outward into the radial through hole 4. The anti-slip spikes 5 act on the road surface to provide anti-slip protection, preventing the rubber wheels from slipping or becoming unable to move. When the vehicle is traveling on a road surface with better conditions, the control cylinder 6 retracts, thereby reducing the size of the elastic steel support ring 3. The elastic steel support ring 3 causes the anti-slip spikes 5 to retract inward into the radial through hole 4, preventing damage to the road surface with better conditions. It is flexible in use and reliable in operation.

[0021] Example 2 Unlike Embodiment 1, the hydraulic cylinder 6 can be replaced by an electric cylinder, with both ends of the electric cylinder hinged to the two ends of the notch in the elastic steel support ring 3.

[0022] Example 3 Unlike Embodiment 1, the hydraulic cylinder 6 can be replaced by a pneumatic cylinder, with both ends of the pneumatic cylinder hinged to the notches of the elastic steel support ring 3.

[0023] It should be noted that the expansion and contraction mechanism can also adopt other methods, as long as it can expand or contract the elastic steel support ring 3.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
