Description

Technical Field

[0001] This utility model belongs to the field of wire rope lubrication and relates to an automatic lubrication device for wire ropes of mining winches. Background Technology

[0002] A wire rope lubrication device for mine winches is a type of electromechanical equipment specifically designed to automatically and evenly apply lubricating grease to the wire ropes used in mine hoists. Its function is to ensure continuous, quantitative, and comprehensive lubrication of the wire ropes through mechanized and automated means. For example, patent (CN222459163U) discloses an automatic oiling device for wire ropes of mining winches, which describes "including a receiving box and an oiling mechanism. Two cotton-coating rollers are rotatably and laterally arranged on the top of the inner cavity of the receiving box. Through openings are provided on the front and rear sides of the receiving box. Oil spraying discs are fixedly connected to the top and middle of the inner cavity of the receiving box. One oil spraying disc is located above the upper cotton-coating roller, and the other oil spraying disc is located below the lower cotton-coating roller. This automatic oiling device for wire ropes of mining winches can extract the oil stored in the inner cavity of the receiving box through the function of the oil pump mechanism and inject it into the interior of the two oil spraying discs. Through several oil spraying nozzles on the surface of the two oil spraying discs, the surface of the two cotton-coating rollers can be coated with oil. After the wire rope passes between the two cotton-coating rollers, the surface of the wire rope can be fully oiled by the two cotton-coating rollers."

[0003] The existing technology has the following technical defects: Because a large amount of coal dust, rock dust and moisture adhere to the surface of steel wire ropes in mines, these contaminants form a mixed isolation layer that hinders the effective contact between grease and the surface of the steel wire rope, leading to lubrication failure. Furthermore, existing technologies do not have efficient and reliable online cleaning devices, making it impossible for lubrication operations to achieve the expected results. Summary of the Invention

[0004] The technical problem this invention aims to solve is that the surface of mining wire ropes accumulates a large amount of coal dust, rock dust, and moisture. These contaminants form a mixed barrier layer, hindering effective contact between the grease and the wire rope surface, leading to lubrication failure. Existing technologies lack efficient and reliable online cleaning devices, preventing lubrication from achieving the desired results. This invention overcomes the shortcomings of existing technologies by providing an automatic lubrication device for mining winch wire ropes. This utility model includes a fuel tank body, on which a cleaning assembly is installed. The cleaning assembly includes a cleaning box. The cleaning box is installed at the rope inlet end of the fuel tank body. The cleaning box has a cleaning cavity inside. Structural holes are opened at both ends of the cleaning cavity. Scrapers are symmetrically fixed to the vertical surface of the cleaning cavity away from the fuel tank body. A fixing frame is installed inside the cleaning cavity near the scraper. A through hole is opened in the middle of the fixing frame. A rotating ring is installed on the vertical surface of the fixing frame near the scraper. Multiple cleaning brushes are connected to the inner circumferential surface of the rotating ring. An annular limiting groove is opened on the vertical surface of the rotating ring near the fixing frame. Multiple limiting blocks are fixed around the through hole on the vertical surface of the fixing frame near the rotating ring. The limiting blocks are inserted into the limiting groove. A linkage assembly is installed on the fuel tank body.

[0005] Preferably, a support frame is installed near the center of the cleaning chamber, and an annular suction pipe is provided in the fixing groove at the top of the support frame. Multiple suction holes are opened around the inner arc surface of the annular suction pipe, and a suction pump is installed at the bottom of the cleaning box. The suction pump is connected to the annular suction pipe through a connecting short pipe.

[0006] Preferably, the scraper is made of wear-resistant polyurethane or special rubber material, and the scraper slides in contact with the outer surface of the wire rope.

[0007] Preferably, the linkage assembly includes gear teeth and a fixed seat. Multiple gear teeth are fixedly connected at equal intervals on the outer circumferential surface of the rotating ring. A fixed seat is installed on the top of the cleaning box. A drive shaft is installed in the fixed seat. Both ends of the drive shaft extend outward through the seat body of the fixed seat. A first gear is installed at the end of the drive shaft near the scraper. A rotating groove is opened on the top of the cleaning box. The bottom of the first gear passes through the rotating groove and meshes with the gear teeth.

[0008] Preferably, rotating rods are symmetrically installed inside the cleaning chamber near one end of the refueling tank. Rotating rollers are fitted around the outside of the cross-section of each rotating rod. The rotating rollers are made of rubber and have an arc-shaped groove around their center. The top of one rotating rod extends through the top plate of the cleaning chamber and is fitted with a second gear. A third gear is rotatably installed on the top of the cleaning chamber near the second gear. The third gear meshes with the second gear. A second bevel gear is installed on the top of the third gear. A first bevel gear is installed at one end of the drive shaft near the second bevel gear and meshes with the third gear.

[0009] Preferably, the bottom ends of both rotating rods extend through the bottom plate of the cleaning box and are connected to a fourth gear, with the two fourth gears meshing with each other.

[0010] Working process or working principle: Through the coordinated operation of the cleaning and linkage components, as the wire rope is pulled, it passes through the structural holes at both ends of the cleaning chamber. Most of the solid particles on the surface of the wire rope are scraped off by the scraper. As the wire rope continues to move, the rotating roller in contact with the wire rope surface rotates, causing the rotating rod to drive the second gear to rotate. The third gear and the second bevel gear follow the second gear. With the cooperation of the drive shaft, the drive shaft drives the first gear to rotate simultaneously. When the first gear rotates, with the assistance of the gear teeth, the rotating ring drives the cleaning brush to move in a circular motion along the surface of the rope. The system uses the movement of a steel wire rope to drive the rotation of the cleaning brush. The portion of the steel wire rope from which solid particles are scraped enters the working area of ​​the cleaning brush, which rotates around the surface of the wire rope to achieve deep cleaning of the gaps in the wire rope. When the swept portion of the wire rope enters the working range of the air extraction port, the air pump operates, generating suction at the opening of the air extraction port to remove residual dust from the surface of the wire rope. This ensures that the wire rope is thoroughly cleaned as it passes through the cleaning box, guaranteeing smooth subsequent lubrication operations and effective lubrication.

[0011] Compared with the prior art, the beneficial effects of this utility model are: By using the cleaning components in conjunction with the lubrication system, most of the adhering solid particles can be removed with a scraper before lubricating the wire rope. Then, a cleaning brush can be used to thoroughly clean the dirt in the gaps. Finally, with the assistance of the air extraction port, the residual dust on the surface of the wire rope can be absorbed, ensuring thorough cleaning of the wire rope and guaranteeing the smooth progress of subsequent wire rope lubrication operations, thus ensuring effective lubrication.

[0012] Through the coordinated operation of the linkage components, when the wire rope is pulled between the rotating rollers, it not only achieves the limiting effect of the wire rope's shuttle position, but also provides driving force for the rotation of the cleaning brush, thus achieving a circumferential cleaning of the wire rope surface.

[0015] Example 1 like Figures 1-4 As shown, an automatic lubrication device for a mining winch wire rope includes a lubrication tank 1, a cleaning assembly installed on the lubrication tank 1, the cleaning assembly including a cleaning box 2, the cleaning box 2 being installed at the rope inlet end of the lubrication tank 1, a cleaning cavity 3 being opened inside the cleaning box 2, structural holes being opened at both ends of the cleaning cavity 3, scrapers 4 being symmetrically fixed to the vertical surface of the cleaning cavity 3 away from the lubrication tank 1, a fixing frame 5 being installed inside the cleaning cavity 3 near the scraper 4, a through hole being opened in the middle of the fixing frame 5, a rotating ring 6 being installed on the vertical surface of the fixing frame 5 near the scraper 4, multiple cleaning brushes 7 being connected to the inner circumferential surface of the rotating ring 6, an annular limiting groove 8 being opened on the vertical surface of the rotating ring 6 near the fixing frame 5, multiple limiting blocks 9 being fixed to the vertical surface of the fixing frame 5 near the rotating ring 6 around the through hole, the limiting blocks 9 being inserted into the limiting groove 8, and a linkage assembly being installed on the lubrication tank 1. Fuel nozzles are installed on the top and both sides of the fuel tank 1. The limiting effect of the limiting block 9 and the limiting groove 8 allows the cleaning brush 7 to rotate around the horizontal central axis of the rotating ring 6, ensuring that the working end of the cleaning brush 7 can contact the surface of the wire rope at the same distance, thus guaranteeing the cleaning effect. The horizontal central axis of the rotating ring 6, the horizontal central axis of the space enclosed by the scraper 4, the horizontal central axis of the structural hole of the cleaning chamber 3, and the horizontal central axis of the through hole of the fixing frame 5 all coincide, which can avoid unnecessary friction between the wire rope and related structures during the cleaning process and reduce the wear and tear of the wire rope.

[0016] A support frame 21 is installed near the center inside the cleaning chamber 3. An annular suction pipe 22 is installed inside the fixing groove at the top of the support frame 21. Multiple suction holes 23 are arranged around the inner arc surface of the annular suction pipe 22. A suction pump 24 is installed at the bottom of the cleaning box 2, and the suction pump 24 is connected to the annular suction pipe 22 via a connecting short pipe. The horizontal central axis of the annular suction pipe 22 coincides with the horizontal central axis of the rotating ring 6.

[0017] The scraper 4 is made of wear-resistant polyurethane or special rubber, and it slides in contact with the outer surface of the wire rope. During the movement of the wire rope, the scraper 4 can remove most of the adhering solid particles, allowing the subsequent cleaning operation of the cleaning brush 7 to proceed smoothly.

[0018] During operation, thanks to the structural design of the cleaning components, as the wire rope is pulled, it passes through the structural holes at both ends of the cleaning chamber 3. Most of the solid particles on the surface of the wire rope are scraped off by the scraper 4. As the wire rope continues to move, the portion of the wire rope with the scraped solid particles enters the working position of the cleaning brush 7. With the cooperation of the linkage components, the rotating ring 6 drives the cleaning brush 7 to rotate around the surface of the wire rope, achieving deep cleaning of the gaps in the wire rope. When the part of the wire rope that has been cleaned enters the working range of the air extraction hole 23, the air pump 24 operates, and the opening of the air extraction hole 23 generates suction, effectively adsorbing the residual dust on the surface of the wire rope. This ensures that the wire rope is thoroughly cleaned when passing through the cleaning box 2, guaranteeing the smooth progress of subsequent lubrication operations and ensuring effective lubrication.

[0019] Example 2 like Figures 1-2 , Figures 4-5 As shown, the linkage assembly includes gear teeth 10 and a fixed seat 11. Multiple gear teeth 10 are fixedly connected at equal intervals on the outer circumferential surface of the rotating ring 6. The fixed seat 11 is installed on the top of the cleaning box 2. A drive shaft 12 is installed in the fixed seat 11. Both ends of the drive shaft 12 extend outward through the seat body of the fixed seat 11. A first gear 13 is installed at the end of the drive shaft 12 near the scraper 4. A rotating groove is opened on the top of the cleaning box 2. The bottom of the first gear 13 passes through the rotating groove and meshes with the gear teeth 10.

[0020] Inside the cleaning chamber 3, symmetrical rotating rods 15 are installed near the end of the refueling tank 1. Rotating rollers 16 are fitted around the outside of the cross section of the rotating rods 15. The rotating rollers 16 are made of rubber and have an arc-shaped groove around their center. The top of one rotating rod 15 extends out through the top plate of the cleaning box 2 and is fitted with a second gear 17. A third gear 18 is rotatably installed on the top of the cleaning box 2 near the second gear 17. The third gear 18 meshes with the second gear 17. A second bevel gear 19 is installed on the top of the third gear 18. A first bevel gear 14 is installed on the end of the drive shaft 12 near the second bevel gear 19. The first bevel gear 14 meshes with the third gear 18. The rotating roller 16 is clamped on both sides of the wire rope through the arc groove. Since the rubber material itself has a large friction force, the rotating roller 16 rotates along the moving wire rope surface during the wire rope shuttle process, and at the same time achieves the limiting effect of the wire rope shuttle position, so as to avoid the wire rope from having a large friction with the cleaning box 2 and the oiling box 1 during the wire rope shuttle process.

[0021] The bottom ends of both rotating rods 15 extend through the bottom plate of the cleaning box 2 and are connected to a fourth gear 20, which meshes with each other. When the rotating roller 16 rotates, the rotating rods 15 drive the second gear 17 and the fourth gear 20 to rotate simultaneously. With the meshing of the two fourth gears 20, the rotating rollers 16 on both sides rotate simultaneously, avoiding excessive friction between the rotating roller 16 on one side and the surface of the wire rope, which would accelerate damage.

[0022] During operation, through the mechanism design of the linkage components, as the wire rope is pulled, the rotating roller 16 rotates, and the rotating rod 15 drives the second gear 17 to rotate accordingly. The third gear 18 and the second bevel gear 19 follow the second gear 17 to rotate. With the cooperation of the transmission shaft 12, the transmission shaft 12 drives the first gear 13 to rotate simultaneously. When the first gear 13 rotates, with the assistance of the gear teeth 10, the rotating ring 6 drives the cleaning brush 7 to make a circular motion along the surface of the rope, so that the cleaning brush 7 can rotate quickly along the surface of the wire rope to clean the gaps in the wire rope. The movement of the wire rope provides the driving force for the rotation of the cleaning brush 7.
