Description

Technical Field

[0001] The utility model relates to the technical field of roller cage ears, in particular to a fixing bracket for a cage roller cage ear. Background Technique

[0002] As an essential structure for the hoisting of mine cages, the stability of the roller cage ears determines the stability of the cage hoisting. For example, in a new type of roller cage ear (patent number: CN201520390424.3) disclosed in Chinese patent literature, the buffer used in the roller cage ear cannot be adjusted by itself. If the roller installed on the roller cage ear wears out during use, although the buffer keeps the roller still in contact with the track, the wear of the roller causes the spring to elongate, and the pressure exerted by the spring on the swing arm will become smaller, which easily leads to jitter of the roller during operation and cannot ensure the stability of the cage lifting process.

[0003] Therefore, we propose a fixing bracket for a cage roller cage ear. Content of the Utility Model

[0004] The purpose of the utility model is to provide a fixing bracket for a cage roller cage ear to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A fixing bracket for a cage roller cage ear, including a base, a swing arm, a roller, a support, and a buffer housing. The support is fixedly installed on the base. A end cover is provided at the top of the buffer housing, and a movable rod is provided inside the buffer housing. A connecting rod is provided at the top of the movable rod. A baffle is provided on the movable rod. A spring is provided at the bottom of the baffle. A threaded rod is provided at the bottom of the buffer housing. A nut is provided on the threaded rod. A bottom plate is provided at the inner bottom of the buffer housing. A through hole is provided at the bottom of the buffer housing. A ejector rod is provided in the through hole.

[0006] Preferably, the top of the movable rod passes through the end cover, and the movable rod is movably connected with the end cover.

[0007] Preferably, two groups of ejector rods are provided, and the tops of the two groups of ejector rods are fixedly installed at the bottom of the bottom plate.

[0008] Preferably, both ends of the swing arm are connected to the base and the connecting rod through shafts, and the roller is installed on the swing arm through a mounting shaft.

[0009] Preferably, the lower part of the threaded rod is connected to the support through a shaft, and the part of the threaded rod above the top of the support is provided with threads.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows: The nut moves upward by cooperating with the threaded rod. The nut contacts the top rod and jacks up the top rod. The top rod pushes the bottom plate upward, and the bottom plate pushes the spring to compress the spring. The spring applies pressure to the movable rod, thereby causing the swing arm to rotate, making the roller provided on the swing arm in close contact with the track, ensuring the stability during the lifting and lowering of the cage. This roller cage ear adjusts the roller by compressing the spring, enabling the roller to run smoothly, thereby improving the stability of the cage lifting and lowering.

[0015] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to 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.

[0016] Please refer to Figures 1-3, the utility model provides a technical solution: a fixing bracket for a roller cage ear of a shaft cage, which includes a base 1, a swing arm 2, a roller 3, a support 4 and a buffer housing 5. The support 4 is fixedly installed on the base 1. An end cover 6 is provided at the top of the buffer housing 5. A movable rod 7 is provided inside the buffer housing 5. A connecting rod 8 is provided at the top of the movable rod 7. A baffle 9 is provided on the movable rod 7. A spring 10 is provided at the bottom of the baffle 9. A threaded rod 11 is provided at the bottom of the buffer housing 5. A nut 12 is provided on the threaded rod 11. A bottom plate 13 is provided at the inner bottom of the buffer housing 5. A through hole 14 is provided at the bottom of the buffer housing 5. A top rod 15 is provided in the through hole 14. When the roller 3 provided on the roller cage ear is worn after being used for a period of time, the roller 3 will be worn, and the distance between the roller 3 and the track will increase, affecting the smoothness of the shaft cage lifting. By using a tool to rotate the nut 12, the nut 12 cooperates with the threaded rod 11 and moves upward. The nut 12 contacts the top rod 15 and jacks up the top rod 15. The top rod 15 pushes the bottom plate 13 upward. The bottom plate 3 pushes the spring 10 and compresses the spring 10, so that the spring 10 applies pressure to the movable rod 7, thereby rotating the swing arm 2 and making the roller 3 provided on the swing arm contact tightly with the track, ensuring the stability during the lifting of the shaft cage. This roller cage ear adjusts the roller by compressing the spring 10, enabling the roller 3 to run smoothly, thereby improving the stability of the shaft cage lifting.

[0017] Among them, the top of the movable rod 7 passes through the end cover 6, and the movable rod 7 is movably connected to the end cover 6. The movable rod 7 can move. When the spring 10 is compressed, the movable rod 7 pushes the swing arm 2 through the connecting rod 8, so that the roller 3 provided on the swing arm 2 contacts the running track without gaps, resulting in the shaking of the shaft cage during operation.

[0018] There are two groups of top rods 15. The tops of the two groups of top rods 15 are fixedly installed at the bottom of the bottom plate 13. The nut rotates to push the top rod 15, and the top rod 15 pushes the bottom plate 13. When pushing the bottom plate 13, the force is evenly distributed, making it easier to push the bottom plate 13 to compress the spring 10.

[0019] Both ends of the swing arm 2 are connected to the base 1 and the connecting rod 8 through shafts. The roller 3 is installed on the swing arm 2 through a mounting shaft. The lower part of the threaded rod 11 is connected to the support 4 through a shaft. The part of the threaded rod 11 above the top of the support 4 is provided with threads.

[0020] Working principle: After the roller 3 provided on the roller cage ear has been used for a period of time, the roller 3 will wear out. When the roller 3 wears out, the distance between the roller 3 and the track increases, affecting the smoothness of the hoist cage lifting in the mine. By using a tool to rotate the nut 12, the nut 12 moves upward in cooperation with the threaded rod 11. The nut 12 contacts the ejector rod 15 and jacks up the ejector rod 15. The ejector rod 15 pushes the bottom plate 13 upward. The bottom plate 3 pushes the spring 10 and compresses the spring 10, so that the spring 10 exerts pressure on the movable rod 7, thereby causing the swing arm 2 to rotate, making the contact tightness between the roller 3 provided on the swing arm and the track, and ensuring the stability during the hoist cage lifting. This roller cage ear adjusts the roller by compressing the spring 10, enabling the roller 3 to run smoothly, thereby improving the stability of the hoist cage lifting.

[0021] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
