Description

Technical Field

[0001] This utility model relates to the field of tire technology, and in particular to an impact-resistant skeleton support structure for non-pneumatic tires used in industrial and mining applications. Background Technology

[0002] Non-pneumatic tires for mining and industrial use eliminate the risk of tire blowouts. They are typically equipped with impact-resistant frames and can absorb shocks through a multi-layered structure. They are adaptable to complex terrain in mines, have high load-bearing capacity and durability, and ensure stable equipment operation. The impact-resistant frame support structure of non-pneumatic tires for mining and industrial use includes drive and buffer components, which can transmit force and reduce shocks, adapt to complex terrain, improve tire impact resistance, and ensure stable equipment operation.

[0003] In the existing technology, the skeleton support structure of some non-pneumatic tires for industrial and mining applications includes core support components, buffer components, transmission connectors, and auxiliary vibration stabilizers. During operation, the core hub rotates with the axle to drive the tire. When encountering bumps in the mine, the force on the tire tread is first absorbed by the deformation of the buffer components, and the remaining force is transmitted to the hub through the transmission components, avoiding the impact from acting directly on the equipment and ensuring durability and equipment stability under complex working conditions.

[0004] In the existing technology, the skeleton support structure of some non-pneumatic tires used in mining and industrial applications causes significant vibration when the equipment is running in the mine, making it difficult to maintain stability during operation and causing discomfort to the driver. Furthermore, the buffer components are not effectively adapted to the mine surface. Therefore, an impact-resistant skeleton support structure for non-pneumatic tires used in mining and industrial applications is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides an impact-resistant frame support structure for non-pneumatic tires used in mining and industrial applications.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An impact-resistant frame support structure for a non-pneumatic tire used in industrial and mining applications includes a protective shell, a shock-absorbing mechanism fixedly connected inside the protective shell, two connectors fixedly connected outside the shock-absorbing mechanism, and two support mechanisms fixedly connected outside the two connectors.

[0011] As a further description of the above technical solution:

[0012] The fixed rod is rotatably connected to a rotating plate, and the rotating plate is rotatably connected to two fixed blocks.

[0032] 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.

[0033] An impact-resistant frame support structure for non-pneumatic tires used in industrial and mining applications, referring to... Figure 1 and Figure 2The invention includes an impact-resistant frame support structure for a non-pneumatic tire used in industrial and mining applications. It comprises a protective shell 1, with a shock-absorbing mechanism 2 fixedly connected inside the protective shell 1. Two connectors 3 are fixedly connected externally to the shock-absorbing mechanism 2, and two support mechanisms 4 are fixedly connected externally to the two connectors 3. The shock-absorbing mechanism 2 includes a fixing plate 21, the bottom of which is fixedly connected to the inside of the protective shell 1, providing a stable mounting base for the entire shock-absorbing mechanism 2. A drive assembly 22 is fixedly connected externally to the fixing plate 21, including an engine 221, which is fixedly connected externally to the top of the fixing plate 21. The engine 221 serves as a power source, and a lower gear 222 is fixedly connected to its drive end. A rotating shaft 22 is rotatably connected inside the protective shell 1. 4. An upper gear 223 is fixedly connected to the outside of the rotating shaft 224. The outside of the upper gear 223 and the outside of the rotating shaft 224 are meshed with each other. When the engine 221 starts, it drives the lower gear 222 to rotate. Through the meshing of the gears, the upper gear 223 is driven to rotate, which in turn drives the rotating shaft 224 to rotate. Multiple nuts 225 are threadedly connected to the left and right sides of the outside of the rotating shaft 224. The rear wheel hub 226 is threadedly connected to the outside of the multiple nuts 225. The nuts 225 serve to fix the rear wheel hub 226, so that the rotation of the rotating shaft 224 can synchronously drive the rear wheel hub 226 to rotate. An air-filled rubber ring 227 is fixedly connected to the outside of the rear wheel hub 226, thereby driving the air-filled rubber ring 227 to rotate and providing power for the operation of the equipment.

[0034] Specifically, after the engine 221 starts, it drives the lower gear 222 to rotate. Through gear meshing, the upper gear 223 and the rotating shaft 224 rotate synchronously. The rotating shaft 224, through the fixing action of the nut 225, drives the rear wheel hub 226 and the pneumatic rubber ring 227 to rotate, forming power output. The fixing plate 21 provides stable support for the engine 221, and the protective shell 1 protects the internal drive component 22. At the same time, the fixing device 23 constrains the rotation trajectory of the rotating rod 24, so that the shock absorption mechanism 2 and the drive component 22 maintain structural coordination during movement, ensuring efficient power transmission while providing basic support for subsequent shock absorption.

[0035] Reference Figure 2 and Figure 3The protective shell 1 has two fixed fasteners 23 inside. A rotating rod 24 is rotatably connected to an adjacent side of each fastener 23, providing a rotational support point for the rotating rod 24. Connecting rod 1 25 is fixedly connected to the left and right sides of the rotating rod 24. Connecting rod 26 is rotatably connected to the outside of connecting rod 1 25. Connecting block 27 is rotatably connected to the outside of connecting rod 26. When connecting block 27 is subjected to force, it drives connecting rod 1 25 to move via connecting rod 26, thereby causing the rotating rod 24 to rotate on the fasteners 23, achieving force transmission and dispersion. Fixed rods 28 are fixedly connected to the upper and lower sides of the connecting block 27. A rotating plate 29 is rotatably connected to the outside of the fixed rods 28. The movement of the connecting block 27 drives the fixed rods 28 to move, causing the rotating plate 29 to rotate along the fixed rods 28. The plate 29 is externally rotatably connected to two fixed blocks 210. The rotation of the plate 29 will act on the fixed blocks 210. The plate 29 is externally fixedly connected to a fixed block 211. The fixed block 211 is externally rotatably connected to a hydraulic device 212. When the plate 29 rotates, it drives the hydraulic device 212 to move through the fixed block 211. The hydraulic device 212 is externally fitted with a spring 213. The upper external end of the hydraulic device 212 is rotatably connected to a fixed block 214. The hydraulic device 212 and the spring 213 cooperate to absorb the impact force through hydraulic action and elastic deformation when squeezed. The fixed block 214 provides an upper connection point for the hydraulic device 212. Through the synergistic effect of the equipment, vibration is further absorbed and weakened, and multi-level buffering and shock absorption are finally achieved to ensure the stable operation of the equipment under complex working conditions.

[0036] Specifically, when the connector 3 vibrates, the connecting block 27 is subjected to force and drives the fixed rod 28 to move, causing the rotating plate 29 to rotate around the fixed rod 28. The rotating plate 29 pushes the hydraulic device 212 to extend and retract through the fixed block 211, while simultaneously squeezing the external spring 213. The elastic deformation of the spring 213 and the internal hydraulic pressure of the hydraulic device 212 together weaken the impact force. When the rotating plate 29 rotates, it also drives the fixed block 210 to move in linkage, and the connecting rod 26 moves with the connecting block 27, pulling the connecting rod 25 to make the rotating rod 24 rotate on the fixture 23, dispersing the stress, and converting the vibration into deformation energy in stages, realizing multi-stage vibration reduction and ensuring equipment stability.

[0037] Reference Figure 1 , Figure 2 and Figure 4The two support mechanisms 4 include two rotating blocks 41. The rotating blocks 41 are externally fixedly connected to the outside of two connectors 3. The connectors 3 can connect the shock-absorbing mechanism 2 and the support mechanism 4 to realize the transmission of force. Multiple circular shims 42 are placed on the outside of the rotating blocks 41 to buffer and adjust the gap. Multiple nuts 43 are threadedly connected to the outside of the rotating blocks 41. The external threads of the multiple nuts 43 are connected to the front wheel hub 44. The nuts 43 are used to fix the front wheel hub 44, so that the rotating blocks 41 are stably connected to the front wheel hub 44. A buffer layer 45 is fixedly connected to the outside of the front wheel hub 44. An outer wheel is fixedly connected to the outside of the buffer layer 45. The hub 46 and the buffer layer 45 can absorb part of the impact force through their own deformation. Multiple fixed shafts 47 are fixedly connected inside the outer hub 46, and leaf springs 48 are fixedly connected to the outside of each fixed shaft 47. The fixed shafts 47 provide fixed support for the leaf springs 48. The leaf springs 48 have good elasticity and can further absorb the impact force. The support frame 49 is fixedly connected to the outside of the leaf springs 48, and an airless rubber ring 410 is fixedly connected to the outside of the support frame 49. The airless rubber ring 410 is in direct contact with the ground. When encountering bumps, the force generated by its deformation is transmitted to the leaf springs 48 through the support frame 49, thereby achieving a double buffering effect and improving the adaptability of the equipment.

[0038] Specifically, when the equipment encounters bumps while traveling in the mine, the airless rubber ring 410 first deforms upon contact with the ground, and the impact force is transmitted to the leaf spring 48 through the support frame 49. The leaf spring 48 elastically deforms around the fixed shaft 47 to absorb part of the force, and the remaining force is transmitted to the buffer layer 45 through the outer hub 46. The buffer layer 45 deforms to relieve the force a second time. The front hub 44 is stably connected to the rotating block 41 through the nut 43. The circular washer 42 eliminates the connection gap. The rotating block 41 transmits the residual vibration to the shock absorption mechanism 2 through the connector 3. All the structures move in coordination, from contact with the ground to the force transmission to the shock absorption mechanism 2, improving the equipment's adaptability to complex terrain.

[0039] The implementation principle of this application embodiment is as follows: First, the engine 221 drives the drive assembly 22 to rotate. The outer side of the upper gear 223 and the outer side of the lower gear 222 are meshed with each other, so that the lower gear 222 drives the upper gear 223 to rotate, thereby driving the rotating shaft 224 to rotate. The rear wheel hub 226 is fixed to the outside of the rotating shaft 224 by the nut 225, thereby driving the rear wheel hub 226 and the pneumatic rubber ring 227 to rotate, thereby providing power for the operation of the equipment.

[0040] When moving in the mine, the airless rubber ring 410 transmits force to the leaf spring 48 through the support frame 49. The leaf spring 48 deforms to absorb most of the force, and then transmits the force to the buffer layer 45 through the outer hub 46. The buffer layer 45 deforms again to absorb the force, thus adapting to the complex terrain of the mine. The force is transmitted to the connecting block 27 through the connector 3 through the front hub 44. When the support mechanism 4 vibrates, the force is transmitted to the hydraulic device 212 and the spring 213 through the rotation of the rotating plate 29. The deformation of the spring 213 and the hydraulic action of the hydraulic device 212 greatly reduce the overall vibration of the equipment.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
