Description

Technical Field

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0033] Refer to Figure 1 and Figure 2 An embodiment provided by the present utility model: An automatic sidewalk lubrication structure includes an oil tank 1 and a support frame 12. A fixed frame 2 is fixedly connected to the bottom of the oil tank 1. A connecting pipe 3 is fixedly connected to the bottom of the oil tank 1. A rotating block 4 is rotatably connected inside the fixed frame 2. An electric push rod 5 is fixedly connected to one side of the rotating block 4. A connecting block 6 is fixedly connected to the output end of the electric push rod 5. A limiting column 8 is fixedly connected to one side of the connecting block 6. One end of the connecting pipe 3 is fixedly connected to a connecting frame 7. The limiting column 8 is rotatably connected inside the connecting frame 7. A through hole 11 is opened inside the limiting column 8. A conveying pipe 9 is fixedly connected inside the connecting frame 7. A piston 10 is slidably connected inside the conveying pipe 9. A cylinder 13 is fixedly connected to the top of the support frame 12. A connecting frame 14 is fixedly connected to the output end of the cylinder 13. The bottom of the connecting frame 14 is fixedly connected to the top end of the piston 10. An oil injector 15 is fixedly connected to the bottom of the connecting frame 7. A conveying assembly is arranged on the outer wall of the oil tank 1, and the conveying assembly is used for injecting oil into the oil tank 1.

[0034] Specifically, when using this lubrication structure to inject oil into the automatic sidewalk, first inject lubricating oil into the oil tank 1. Subsequently, through the output end of the cylinder 13, the connecting frame 14 is driven to move, thereby pushing the piston 10 connected to the bottom to move inside the conveying pipe 9. The movement of the piston 10 causes the lubricating oil in the oil tank 1 to be pumped into the inside of the limiting column 8 through the connecting pipe 3. At the same time, the output end of the electric push rod 5 drives the connecting block 6 to move, and the connecting block 6 drives the limiting column 8 to rotate inside the connecting frame 7, so that two of the three through holes 11 in the limiting column 8 are docked with the conveying pipe 9 and the oil injector 15, and the other side closes the output end of the connecting pipe 3. Subsequently, the cylinder 13 moves the piston 10 in the reverse direction, pushing the lubricating oil in the oil tank into the oil injector 15, and precisely injecting the lubricating oil through the oil injector 15 to ensure that the oil injection volume each time remains consistent, effectively maintaining and optimizing the lubrication state of the automatic sidewalk, and ensuring its stable operation and long-term reliability.

[0035] Refer to Figure 1 、 Figure 3 and Figure 4The delivery component includes an oil filling pipe 16, which is fixedly connected to the outer wall of the oil tank 1. A rotating shaft 17 is provided on the outer wall of the oil filling pipe 16. A sealing cover 18 is rotatably connected to the outer wall of the rotating shaft 17. A supporting plate 19 is fixedly connected to the outer wall of the sealing cover 18. The outer wall of the oil filling pipe 16 is fixedly connected to a limit frame 20. A sliding column 22 is slidably connected inside the fixing ring 21. The sliding column 22 is slidably connected inside the limit frame 20. A connecting ring 23 is fixedly connected to the outer wall of the sliding column 22.

[0036] Specifically, when the oil tank 1 needs to be filled with oil, the operator can move the lever 24 to make the connecting ring 23 start to move. The connecting ring 23 is forced to drive the internally connected sliding column 22 to slide out of the limit frame 20. This process opens the sealing cover 18, exposing the input end of the oil filling pipe 16 to facilitate the injection of lubricating oil.

[0037] Reference Figure 1 , Figure 3 and Figure 4 The sealing cover 18 is connected to the oil filling pipe 16 through the sealing cover 18, a fixing ring 21 is fixedly connected to one side of the support plate 19, a lever 24 is fixedly connected to the outer wall of the connecting ring 23, a connecting plate 25 is fixedly connected to one side of the support plate 19, the lever 24 is slidably connected inside the connecting plate 25, a spring 26 is sleeved on the outer wall of the sliding column 22, one end of the spring 26 is fixedly connected to the outer wall of the fixing ring 21, and the other end of the spring 26 is fixedly connected to the outer wall of the connecting ring 23.

[0038] Specifically, after the oil filling is completed, the sealing cover 18 is rotated back to its original position by rotating the rotating shaft 17, thereby closing the oil filling pipe 16. During this process, the sliding column 22 on the outer wall of the sealing cover 18 contacts the limiting frame 20 on the outer wall of the oil filling pipe 16, causing the sliding column 22 to slide inward into the interior of the fixing ring 21, while pushing the connecting ring 23 connected to the outer wall to move, squeezing the spring 26 connected to the outer wall to shrink it. When the sealing cover 18 is completely closed and sealed, the force released by the spring 26 causes the connecting ring 23 and the sliding column 22 to return to their original positions, and the sliding column 22 slides into the limiting frame 20 again, ensuring that the sealing inside the oil tank 1 is restored and maintained, effectively simplifying the maintenance process of the oil tank, so that it can maintain efficient operation and reliable sealing performance during the oil filling and sealing process.

[0039] Working principle: When using this lubrication structure to inject oil into the moving walkway, first pour the lubricating oil into the interior of the fuel tank 1. The output end of the cylinder 13 drives the connecting frame 14 to move. The connecting frame 14 drives the piston 10 connected to the bottom to move inside the delivery pipe 9 under force. Then, through the movement of the piston 10, the lubricating oil inside the fuel tank 1 is pumped into the limiting column 8 through the connecting pipe 3. At this time, the output end of the electric push rod 5 drives the connecting block 6 to move. The connecting block 6 drives the limiting column 8 connected to one side to rotate inside the connecting frame 7 under force. Three through holes 11 are provided inside the limiting column 8. By rotating, two of the sides of the through holes 11 provided inside the limiting column 8 are respectively attached to the delivery pipe 9 and the oil injector 15, and at the same time, the closed side of the limiting column 8 is rotated to the output end of the connecting pipe 3 to block it. Then, the output end of the cylinder 13 drives the piston 10 to move in the reverse direction, and then the lubricating oil inside is pushed into the oil injector 15 and injected through the oil injector 15, thereby achieving the effect that the dosage of the lubricating oil injected each time can be kept consistent. When it is necessary to fill the fuel tank 1 with oil, the lever 24 can be toggled to drive the connecting ring 23 to move. The connecting ring 23 drives the sliding column 22 connected inside to slide out of the limiting frame 20, thereby opening the sealing cover 18 from the input end of the oil injection pipe 16. Then, after the oil filling is completed, the sealing cover 18 is rotated back to its original position to close the oil injection pipe 16 through the action of the rotating shaft 17. During this process, the sliding column 22 on the outer wall of the sealing cover 18 will contact the limiting frame 20 on the outer wall of the oil injection pipe 16, causing the sliding column 22 to slide into the fixed ring 21 under force. The sliding column 22 drives the connecting ring 23 connected to the outer wall to move. The connecting ring 23 squeezes the spring 26 connected to the outer wall under force, causing it to contract. When the sealing cover 18 is completely closed and sealed with the oil injection pipe 16, at this time, the spring 26 rebounds after unloading, and then drives the connecting ring 23 and the sliding column 22 to reset, causing the sliding column 22 to slide into the limiting frame 20 to complete the fixation, thereby achieving the effect of facilitating the sealing of the fuel tank 1.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
