Description

Technical Field

[0001] This utility model relates to the technical field of refueling devices, and in particular to an online automatic refueling device for the wheels of a sintering machine trolley. Background Technology

[0002] During the production process of the sintering machine, the sintering machine trolley needs to maintain continuous operation. Due to the harsh working conditions such as high temperature, heavy load, impact vibration, dust erosion and water spray during the operation of the sintering machine trolley, the bearing wear is accelerated, and the requirements for lubricating grease replenishment are high.

[0003] The sintering machine trolleys are numerous, and the wheels and rollers of each trolley require lubrication with grease. Each sintering machine trolley has multiple sets of wheels and rollers, with two grease inlets per set. Currently, in actual production, maintenance requires machine shutdown, and grease is manually applied using an grease gun. This requires three shifts per person per shift to complete, which is inconvenient and time-consuming. To address this technical problem, this application proposes an online automatic grease-applying device for the wheels of sintering machine trolleys. Utility Model Content

This device can automatically follow the movement of the sintering machine trolley and automatically inject lubricating oil into the wheels of the sintering machine trolley, thereby effectively improving the operating efficiency of the production line.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An online automatic oiling device for the wheels of a sintering machine trolley includes a lathe connected to a mounting plate via a moving component. A first fixed frame is mounted on the front side of the mounting plate, and a second fixed frame is mounted on the rear side of the mounting plate.

A wheel is provided on the outer wall of the roller, and a track is provided on the bottom side of the wheel.

[0007] Furthermore, the moving component includes slide rails located on both sides of the top of the lathe. A servo motor is mounted on the right side of the lathe via a fixed bracket. An adjuster is provided at the drive end of the servo motor. A threaded rod is provided on the inner wall of the adjuster. A slider is threadedly connected to the outer wall of the threaded rod.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1-2 One embodiment of this utility model provides an online automatic oiling device for the wheels of a sintering machine trolley, including a lathe 1. The lathe 1 is connected to a mounting plate 3 via a moving component. A fixing frame 8 is installed on the front side of the mounting plate 3, and a fixing frame 9 is installed on the rear side of the mounting plate 3. An electric push rod 11 is provided on the inner wall of the fixing frame 9. An oiling mechanism is provided at the driving end of the electric push rod 11. A limit frame 10 is installed on the top right side of the mounting plate 3. An electric push rod 21 is installed on the inner wall of the limit frame 10. A connecting rod 22 is provided at the driving end of the electric push rod 21. A roller 23 is provided at the front end of the connecting rod 22. A wheel 13 is provided on the outer wall of the roller 23. A track 12 is provided on the bottom side of the wheel 13.

[0023] Specifically, when the trolley needs refueling, the electric push rod 21 on the top limit bracket 10 of the mounting plate 3 will push the connecting rod 22 forward, so that the roller 23 reaches the front end of the wheel 13. Then the wheel 13 runs on the track 12 and abuts against the roller 23, thereby driving the mounting plate 3 forward together. At the same time, the moving component on the lathe 1 will drive the mounting plate 3 to move synchronously. Then the electric push rod 11 on the fixed bracket 29 will push the oiling mechanism forward. Then the oiling mechanism will inject lubricating oil into the wheel 13. Then the electric push rod 11 will pull the oiling mechanism back, and the moving component will reset the mounting plate 3 on the top of the lathe 1 to start the next round of oiling.

[0024] Reference Figures 2-3The moving component includes slide rails 2 located on both sides of the top of the lathe 1. A servo motor 5 is mounted on the right side of the lathe 1 via a fixed bracket. An adjuster 6 is provided at the drive end of the servo motor 5. A threaded rod 7 is provided on the inner wall of the adjuster 6. A slider 4 is threadedly connected to the outer wall of the threaded rod 7. The top of the slider 4 is fixedly connected to the mounting plate 3. The threaded rod 7 is driven to rotate by two servo motors 5. The adjuster 6 controls the rotation speed of the threaded rod 7, so that the two threaded rods 7 rotate synchronously, thereby causing the slider 4 at the bottom of the mounting plate 3 to reciprocate in the slide rails 2 at the top of the lathe 1.

[0025] The lubrication mechanism includes a fixed plate 14 located at the drive end of the electric push rod 11. Multiple connecting rods 15 are fixedly connected to the front outer wall of the fixed plate 14. An oil reservoir 18 is fixedly connected to the front end of the multiple connecting rods 15. An oil inlet 19 is fixedly connected to the front end of the oil reservoir 18. An oil inlet pipe 20 is provided on the left outer wall of the oil reservoir 18. A piston assembly is provided on the inner wall of the oil reservoir 18. A one-way membrane 24 is installed inside the oil inlet 19 and the oil inlet pipe 20. An mounting plate 16 is fixedly connected to the outer wall of the connecting rod 15. The inner wall of the mounting plate 16 is connected to the outer wall of the electric push rod 17. The fixed plate 14 is pushed forward by the electric push rod 11, thereby driving the multiple connecting rods 15 and the oil reservoir 18 to move forward, so that the oil inlet 19 touches the part of the wheel 13 that needs lubrication. Then, the internal piston assembly adds lubricating oil to the wheel 13 through the oil inlet 19. The one-way membrane 24 installed inside the oil inlet 19 and the oil inlet pipe 20 prevents the lubricating oil from flowing back.

[0026] The piston assembly includes a piston plate 25 slidably connected to the inner wall of the oil reservoir 18. A push rod 26 is fixedly connected to the outer wall of the piston plate 25. The end of the push rod 26 is connected to the drive end of the electric push rod 17. The outer wall of the oil reservoir 18 is slidably connected to the fixed frame 8. The outer wall of the push rod 26 is slidably connected to the oil reservoir 18. The push rod 26 is driven to move by the electric push rod 17, thereby causing the piston plate 25 to press forward in the oil reservoir 18, so that the lubricating oil is discharged from the oil inlet 19. When the piston plate 25 moves backward, it will draw the lubricating oil into the oil reservoir 18 through the oil inlet pipe 20.

[0027] Working principle: When the trolley needs refueling, the electric push rod 21 on the top limit bracket 10 of the mounting plate 3 pushes the connecting rod 22 forward, causing the roller 23 to reach the front end of the wheel 13. The wheel 13 then runs on the track 12 and abuts against the roller 23. Simultaneously, two servo motors 5 drive the threaded rod 7 to rotate, and the regulator 6 controls the rotation speed of the threaded rod 7, causing the two threaded rods 7 to rotate synchronously. This causes the slider 4 at the bottom of the mounting plate 3 to move in the slide rail 2 at the top of the lathe 1, thus driving the mounting plate 3 forward synchronously. The electric push rod 11 then pushes the fixed plate 14 forward, thereby... Multiple connecting rods 15 and oil reservoir 18 are moved forward, so that the oil inlet 19 is pressed against the part of wheel 13 that needs to be oiled. The push rod 26 is driven by electric push rod 27 to move, so that piston plate 25 is squeezed forward in oil reservoir 18, so that lubricating oil is discharged from oil inlet 19. When piston plate 25 moves backward, it will draw lubricating oil into oil reservoir 18 through oil inlet pipe 20. One-way membranes 24 installed inside oil inlet 19 and oil inlet pipe 20 will prevent lubricating oil from flowing back. Then, electric push rod 11 pulls the oiling mechanism back, and the moving component resets the mounting plate 3 on top of lathe 1, and the next round of oiling begins.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
