Description

Technical Field

[0001] This utility model relates to the field of mining machinery technology, and in particular to a vibration reduction and stabilization structure for a large mining hoisting container. Background Technology

[0002] During the high-speed heavy-load hoisting process in deep wells, the hoisting speed and mass increase due to the increased mining depth, so the hoisting container will also be enlarged accordingly. In order to ensure the stability of the hoisting container, a set of lugs is installed at the top and bottom of the hoisting container. The lugs move up and down along the guide rail to provide necessary guidance and support.

[0003] However, during operation or production, the hoisting system inevitably has certain defects, such as surface quality issues, poor joints, and overall deformation. Due to excessive spacing between the upper and lower sets of can ears, when the roller can ears pass over these defects, a significant lateral impact force is generated, resulting in lateral vibration. This severe lateral vibration not only accelerates wear on the roller can ears, increasing the risk of hoisting system deformation, but also, when the amplitude of the rigid hoisting system defect is large, it can easily cause the hoisting container to tilt, seriously affecting hoisting safety. Furthermore, relying solely on the top and bottom can ears for guidance and support also presents certain safety hazards. If one set of can ear rollers is damaged or the fixing bolts loosen, the hoisting container can easily lose its guidance, leading to a safety accident. Utility Model Content

[0004] The purpose of this utility model is to provide a vibration reduction and stabilization structure for a large mining hoisting container. By adding an auxiliary wheel set structure to the hoisting container, the support points between the hoisting container and the guide rail are increased, thereby reducing the pressure on the roller ear, mitigating lateral vibration caused by defects in the guide rail, reducing safety hazards of the hoisting container during operation, and reducing the wear of the ear and guide rail.

[0005] To achieve the above objectives, this utility model provides a vibration reduction and stabilization structure for a large mining hoisting container, including an auxiliary wheel assembly structure installed on the left and right sides of the hoisting container and located between the roller can ear assemblies at its top and bottom; the auxiliary wheel assembly structure includes a fixed frame installed on the side wall of the hoisting container, the fixed frame is provided with a groove for the can passage on the corresponding side to be inserted, and several auxiliary wheels are rotatably installed on the two groove walls and the bottom wall of the groove, the wheel surface of the auxiliary wheels is in close contact with the side wall of the can passage and rolls up and down along it.

[0006] By adopting the above structure and adding auxiliary wheels to the hoisting container, the force borne by each roller lug assembly is reduced, effectively dispersing and bearing the lateral impact force generated by the hoisting container on the guideway during operation, mitigating the lateral vibration of the hoisting container, reducing wear on the top and bottom roller lug assemblies, and reducing the occurrence of safety accidents. It also provides a certain safety redundancy; if one set of roller lug assemblies malfunctions, such as damaged rollers or loose fixing bolts, the other sets of roller lug assemblies and auxiliary wheels can still ensure the basic operational safety of the hoisting container in the shaft, preventing the hoisting container from immediately losing guidance and causing danger, and allowing maintenance personnel sufficient repair time.

[0007] Preferably, the auxiliary wheel includes a base fixed to the channel and a roller assembly mounted on the base. The roller assembly is fixed to the base by a telescopic rod, and a return spring is sleeved on the outer side of the telescopic rod. The roller assembly includes a roller bracket and a roller rotatably mounted on the roller bracket. The wheel surface of the roller is in close contact with the side wall of the channel and rolls up and down along it. This structure allows the auxiliary wheel to have a certain degree of elasticity, better adapting to the slight deformation of the channel, while further reducing vibration.

[0008] Preferably, the fixed frame is mounted on the side wall of the lifting container by a swinging connector; the swinging connector includes a swing arm, one end of which is rotatably mounted on the fixed frame, and the other end is rotatably mounted on the side wall of the lifting container. This swinging mounting method not only improves the adaptability of the auxiliary wheel assembly structure to the tilting and swinging of the lifting container, but also further enhances the overall vibration reduction effect.

[0009] Preferably, each fixed frame is oscillatingly mounted on the side wall of the lifting container via four oscillating connectors, with the four connectors located at the four corners of the fixed frame. This installation method ensures the stability and reliability of the fixed frame, further improving the overall performance of the vibration-damping and stabilizing structure.

[0010] Preferably, three auxiliary wheels are rotatably mounted on each of the two side walls and the bottom wall of the channel. This structure effectively disperses and absorbs lateral impact forces, ensuring that the working surface of each channel has sufficient support.

[0011] Preferably, multiple auxiliary wheel sets are installed on both the left and right sides of the lifting container. The arrangement of multiple auxiliary wheel sets can further improve the stability and safety of the lifting container, ensuring that it can maintain good operating condition during high-speed heavy-load lifting.

[0012] After adopting the above technical solution, the beneficial effects of this utility model are:

[0013] This utility model provides a vibration reduction and stabilization structure for a large mining hoisting container, which solves the technical problems of safety hazards and wear on the can ears and can tracks during the operation of existing hoisting containers. By adding an auxiliary wheel set structure to the hoisting container, this utility model increases the support points between the hoisting container and the can tracks, thereby reducing the pressure on the roller can ears, mitigating lateral vibration caused by defects in the can tracks, and reducing safety hazards and wear on the can ears and can tracks during the operation of the hoisting container.

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] The orientations mentioned in this specification are based on the orientation of the vibration reduction and stabilization structure of the large mining hoisting container of this utility model when it is working normally. They do not limit the orientation during storage and transportation, and only represent relative positional relationships, not absolute positional relationships.

[0023] like Figures 1-3As shown, a vibration-damping and stabilizing structure for a large mining hoisting container includes an auxiliary wheel assembly structure 3 installed on the left and right sides of the hoisting container 1 and located between the roller ear assemblies 2 at its top and bottom. The specific structure and installation method of the hoisting container 1 and the roller ear assemblies 2 can be found in relevant prior art, such as Chinese Patent CN 107473038 A, and will not be repeated here. In this embodiment, an auxiliary wheel assembly structure 3 is installed on each of the left and right sides of the hoisting container 1. This auxiliary wheel assembly structure 3 is located in the middle of the roller ear assemblies 2 at the top and bottom. In practical applications, multiple sets of auxiliary wheel assembly structures 3 can be flexibly installed on the left and right sides of the hoisting container 1 according to its height and stability requirements. The setting of multiple sets of auxiliary wheel assembly structures 3 can further improve the stability and safety of the hoisting container 1, ensuring good operating conditions during high-speed heavy-load hoisting.

[0024] The auxiliary wheel assembly structure 3 includes a fixed frame 31 mounted on the side wall of the lifting container 1. The fixed frame 31 is provided with a groove 311 for the corresponding side of the tank passage 4 to engage. Several auxiliary wheels 32 are rotatably mounted on the two side walls and the bottom wall of the groove 311, respectively. The wheel surfaces of the auxiliary wheels 32 are in close contact with the side wall of the tank passage 4 and roll up and down along it. By rotatably mounting the auxiliary wheels 32 on the two side walls and the bottom wall of the groove 311, it is ensured that the auxiliary wheels 32 in three directions are in close contact with the three working surfaces of the tank passage 4, thereby achieving a clamping and limiting function. By adding auxiliary wheels 32 to the lifting container 1, the force borne by each roller ear assembly 2 is reduced, effectively dispersing and bearing the lateral impact force generated by the lifting container 1 on the tank passage 4 during operation, reducing the lateral vibration of the lifting container 1, reducing the wear of the top and bottom roller ear assemblies 2 of the lifting container 1, and reducing the occurrence of safety accidents. At the same time, it provides a certain safety redundancy. When one of the roller ear groups 2 fails, such as the rollers of roller ear group 2 being damaged or the fixing bolts being loose, the other roller ear groups 2 and auxiliary wheels 32 can still ensure the basic operational safety of the lifting container in the shaft, so that the lifting container 1 will not immediately lose its guidance and cause danger, and leave a certain amount of maintenance time for maintenance personnel.

[0025] To more effectively disperse and withstand lateral impact forces, three auxiliary wheels 32 are evenly installed on the two walls and the bottom wall of the channel 311 to ensure that each working surface of the tank channel 4 has sufficient support. That is, there are three auxiliary wheels 32 on each working surface of the tank channel 4; of course, the number of auxiliary wheels 32 can also be adjusted according to actual needs to achieve the best vibration reduction effect.

[0026] The auxiliary wheel 32 can adopt the same structure as the roller can ear assembly 2, or it can adopt a different structure. In this embodiment, in order to simplify its structure and adapt to installation, the following structure is adopted.

[0027] like Figure 4 and Figure 5 As shown, the auxiliary wheel 32 includes a base 321 fixed on the channel 311 and a roller assembly 322 mounted on the base 321. The roller assembly 322 is fixed to the base 321 by a telescopic rod 323, and a return spring 324 is sleeved on the outer side of the telescopic rod 323. The roller assembly 322 includes a roller bracket and a roller rotatably mounted on the roller bracket. The roller surface is in close contact with the side wall of the channel 4 and rolls up and down along it. This structure allows the auxiliary wheel 32 to have a certain degree of elasticity, better adapting to the slight deformation of the channel 4, while further reducing vibration. Specifically, under the action of the return spring 324, the roller is always in contact with the channel 4. When the lifting container 1 encounters a defect in the channel 4 during operation, the roller assembly 322 quickly rebounds under the action of the damping spring, contacting the channel 4, reducing the wear of the roller ear assemblies 2 at the top and bottom of the lifting container 1 due to the lateral impact force when passing through the defect in the channel 4, thereby reducing the lateral vibration of the lifting container.

[0028] Because the wire rope is prone to longitudinal vibration when the lifting container 1 is running at high speed, causing the lifting container 1 to tilt, this embodiment further improves the structure based on the above.

[0029] like Figure 3 and Figure 6 As shown, the fixed frame 31 is mounted on the side wall of the lifting container 1 by a swinging connector 33. The swinging connector 33 includes a swing arm 331, one end of which is rotatably mounted on the fixed frame 31, and the other end is rotatably mounted on the side wall of the lifting container 1. This swinging mounting method not only improves the adaptability of the auxiliary wheel assembly structure 3 to the tilting and swinging of the lifting container 1, but also further enhances the overall vibration reduction effect.

[0030] To ensure stability and reliability, each mounting bracket 31 is preferably oscillatingly mounted on the side wall of the lifting container 1 via four oscillating connectors 33 located at its four corners. This mounting method ensures the stability and reliability of the mounting bracket 31, further improving the overall performance of the vibration damping and stabilizing structure.

[0031] By setting the swing connector 33, even if the lifting container 1 tilts due to various defects or longitudinal vibration of the wire rope, the swing arm 331 can rotate synchronously with the lifting container 1, ensuring that the auxiliary wheel 32 always keeps in contact with the tank passage 4, thereby effectively reducing safety hazards.

[0032] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
