[0002] The connecting shaft lubrication equipment for mine dampers is a device specially used for lubricating the connecting shaft of mine dampers. Its main function is to ensure good lubrication of the connecting shaft of the mine damper to reduce friction and wear. The equipment can regularly and accurately supply an appropriate amount of lubricating oil to the connecting shaft, maintain the oil film on the surface of the connecting shaft, reduce the friction between mechanical parts, make the opening and closing of the damper smoother, and reduce the probability of failure. At the same time, it also has a certain sealing performance, which can prevent lubricating oil leakage and dust and impurities in the mine from entering the connecting shaft, avoiding aggravated wear due to the mixing of impurities, effectively extending the service life of the connecting shaft and related components, ensuring the normal operation of the mine damper, and thus ensuring the stability and reliability of the mine ventilation system.

[0004] In order to facilitate the staff to accurately observe the content of the lubricating fluid, the lubricating fluid container is set to a transparent material. However, due to the dim environment and insufficient light in the mine, there is a lot of dust in the mine, which easily adheres to the surface of the transparent container and blocks the line of sight. Therefore, it is difficult for the staff to accurately see the content of the lubricating fluid in the container. This may lead to the failure to detect the lack of lubricating fluid in time, affecting the normal lubrication of the connecting shaft and increasing the risk of equipment wear.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In the present invention, when the mine air door is used with a connecting shaft lubricating device, the cylinder drives the sealed push plate to descend, so that the lubricating liquid in the container body is discharged from the discharge mechanism. At this time, the magnetic plate 1 will descend as the sealed push plate descends. When the sealed push plate moves to the bottom of the container body, the magnetic plate 1 will approach the magnetic plate 2.

[0018] In the present invention, the limiting column provides a vertical movement track for the magnetic plate 2, ensuring that the magnetic plate 2 can only move linearly along the axial direction of the limiting column when it is adsorbed or released by the magnetic plate 1, avoiding deviation or shaking, and ensuring the stability of the mechanism's movement.

[0019] In the present invention, the protective plate is slidably connected to the T-shaped slider of the L-shaped plate through a T-shaped groove to form a movable protective structure, which can prevent impurities such as coal dust and rock chips in the mine environment from entering the protective rectangular frame, avoiding these impurities from clogging the discharge mechanism or affecting the normal output of the lubricating fluid, thereby extending the service life of the equipment.

[0032] Working principle:

[0033] In the first step, when the mine air door is used with a connecting shaft lubrication device, the cylinder 13 drives the closed push plate 14 to descend, so that the lubricating liquid in the container body 11 is discharged from the discharge mechanism. At this time, the magnetic plate 19 will descend as the closed push plate 14 descends. When the closed push plate 14 moves to the bottom of the container body 11, the magnetic plate 19 will approach the magnetic plate 21. At this time, the magnetic plate 21 will be adsorbed by the magnetic plate 19. The magnetic plate 21 will drive the connecting block 27 and the rectangular metal plate 1 23 to rise until the connecting block 27 is against the fixed rectangular frame 16 in the long slot 20. At this time, the rectangular metal plate 1 23 is in the middle position of the fixed rectangular frame 16, and the servo motor 26 is always started. The servo motor 26 will drive the rotating long column 25 and the rectangular metal plate 2 24 to rotate, and the rectangular metal plate 1 23 located in the middle of the fixed rectangular frame 16 will press the rectangular metal plate 2 24 performs motion interference. When the rectangular metal plate 24 rotates, it will slap the rectangular metal plate 1 23, so that the rectangular metal plate 1 23 and the magnetic plate 2 21 fall back to the bottom of the fixed rectangular frame 16. When the rectangular metal plate 24 no longer slaps the rectangular metal plate 1 23, the magnetic plate 2 21 will drive the rectangular metal plate 1 23 to continue to rise, so that the rectangular metal plate 2 24 repeatedly slaps the rectangular metal plate 1 23. The servo motor 26 drives the rectangular metal plate 24 to rotate and slap the rectangular metal plate 1 23. This slapping action will produce sound and vibration, avoiding the difficulty of the staff in directly observing the lubricant content in a dim and dusty environment. No matter how dim the ambient light is or how much dust there is, this mechanical action can be used to prompt that the lubricant is about to run out, so that the staff can discover the lack of lubricant in time, reducing the risk of equipment wear.

[0034] In the second step, the limiting column 22 provides a vertical motion track for the magnetic plate 21, ensuring that the magnetic plate 21 can only move linearly along the axial direction of the limiting column 22 when it is adsorbed or released by the magnetic plate 19, avoiding deviation or shaking, and ensuring the stability of the mechanism movement.

[0035] In the third step, the protective plate 30 is slidably connected to the T-shaped slider 29 of the L-shaped plate 28 through the T-shaped groove 31 to form a movable protective structure, which can prevent impurities such as coal dust and rock chips in the mine environment from entering the protective rectangular frame 15, avoiding these impurities from clogging the discharge mechanism or affecting the normal output of the lubricating fluid, thereby extending the service life of the equipment.

[0036] The embodiments of the present invention are presented for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art.
