The reinforcing layer 102 adopts thermal spray WC-Co coating. The transition layer 103 adopts nickel plating. The wear-resistant layer 104 adopts self-lubricating polytetrafluoroethylene (PTFE) composite coating. The protective layer 105 adopts nano-ceramic coating. The two sides of the mounting plate 2 are fixedly installed with connecting plates 20. The top of the connecting plate 20 is symmetrically provided with mounting holes 21.

[0027] In this embodiment, by pulling the pull block 13, the sliding rod 11 is driven to slide in the side pipe 10, and the sealing piston 12 at the other end of the sliding rod 11 is moved, so that the side pipe 10 and the connecting pipe 3 are communicated, at this time, the lubricating oil in the oil storage tank 4 flows to the inside of the bearing seat body 1 through the connecting pipe 3 and the side pipe 10 under the action of its own gravity, lubricating the bearings and other components, after releasing the pull block 13, the reset spring 15 pushes the sealing piston 12 to reset, resealing the side pipe 10 and the connecting pipe 3, preventing the lubricating oil from continuously flowing out, this design accurately solves the problem of lack of lubrication, provides timely lubrication for bearings and other components, greatly reduces the friction coefficient between components, effectively reduces wear and tear, and significantly improves the service life of the bearing seat body 1, which is in sharp contrast with the high wear caused by lack of lubrication in the background art.

[0028] Embodiment 2: As shown in Figures 1-2 The top of the mounting plate 2 is fixedly provided with a guide rod 16, the top of the guide rod 16 is fixedly provided with a limiting block 17, the top of the mounting plate 2 is rotatably connected with a threaded rod 18, the top of the threaded rod 18 is fixedly provided with a handle 19, the guide rod 16 is slidably connected with the bearing seat body 1, and the threaded rod 18 is threadedly connected with the bearing seat body 1.

[0029] In this embodiment, by rotating the handle 19, the threaded rod 18 is driven to rotate on the top of the mounting plate 2, since the threaded rod 18 is threadedly connected with the bearing seat body 1, as the threaded rod 18 continuously rotates, the bearing seat body 1 will displace along the axial direction of the threaded rod 18, in this process, the guide rod 16 plays a crucial auxiliary role, the guide rod 16 is slidably connected with the bearing seat body 1, and the top of the guide rod 16 is fixedly provided with the limiting block 17, which enables the bearing seat body 1 to move smoothly along the straight trajectory defined by the guide rod 16 during the lifting or lowering process, avoiding deviation or shaking, thereby ensuring the accuracy and stability of the adjustment process, the height adjustment structure can quickly and accurately adjust the bearing seat body 1 to the appropriate height, improving the versatility and working efficiency of the equipment.

[0030] The working principle of the embodiment is as follows: when it is necessary to lubricate the inside of the bearing seat body 1, the pull block 13 is first pulled to drive the sliding rod 11 to slide in the side pipe 10, and the sealing piston 12 at the other end of the sliding rod 11 moves to make the side pipe 10 communicate with the connecting pipe 3. At this time, the lubricating oil in the oil storage tank 4 flows to the inside of the bearing seat body 1 through the connecting pipe 3 and the side pipe 10 under the action of its own gravity to lubricate the bearings and other components. After the pull block 13 is loosened, the reset spring 15 pushes the sealing piston 12 to reset to reseal the side pipe 10 and the connecting pipe 3, preventing the lubricating oil from continuously flowing out. The bearing seat body 1 is composed of multiple layers. The base layer 101 is made of 42CrMo alloy steel, which has high strength and good toughness and can withstand large external force impact and pressure to provide solid foundation support for the entire bearing seat body 1. The reinforcing layer 102 is made of a thermal sprayed WC-Co coating, which further improves the strength and wear resistance of the bearing seat body 1. The WC-Co coating has high hardness and can effectively resist wear. The nickel plating layer of the transition layer 103 plays a good transition role, improves the bonding force between the reinforcing layer 102 and the wear-resistant layer 104, and also has certain corrosion resistance. The wear-resistant layer 104 is made of a self-lubricating polytetrafluoroethylene (PTFE) composite coating, which not only has excellent wear resistance but also has self-lubricating effect in the friction process to reduce friction and wear. The protective layer 105 is made of a nano ceramic coating, which has high hardness and good chemical stability and can effectively prevent the erosion of the external environment on the bearing seat body 1 to protect the internal structure and further improve the wear resistance and corrosion resistance of the bearing seat body 1. When it is necessary to adjust the use height of the bearing seat body 1, the handle 19 is first rotated to drive the threaded rod 18 to rotate on the top of the mounting plate 2. Since the threaded rod 18 is in threaded connection with the bearing seat body 1, the bearing seat body 1 will displace along the axial direction of the threaded rod 18 with the continuous rotation of the threaded rod 18. In this process, the guide rod 16 plays a crucial auxiliary role. The guide rod 16 is in sliding connection with the bearing seat body 1, and the top of the guide rod 16 is fixed with the limit block 17, which enables the bearing seat body 1 to move stably along the straight trajectory defined by the guide rod 16 during the lifting or lowering process to avoid deviation or shaking, thereby ensuring the accuracy and stability of the adjustment process. The height adjustment structure can quickly and accurately adjust the bearing seat body 1 to the appropriate height to improve the universality and working efficiency of the equipment.
