Description

Technical Field

[0001] This utility model relates to the field of elevator safety technology, and in particular to an automatic lubrication device for elevator wire ropes. Background Technology

[0002] Elevator wire ropes are flexible load-bearing components made of multiple strands of high-strength steel wire twisted together around a central core. They are used to support the weight of the elevator car and counterweight and transmit power, requiring high strength, wear resistance, and fatigue resistance. During operation, wire ropes experience fretting friction and wear. Prolonged lack of lubrication leads to hardening of the wire rope, decreased fatigue resistance, and increased risk of wire breakage. Therefore, an automatic lubrication system for elevator wire ropes is necessary.

[0003] An automatic lubrication device for elevator wire ropes effectively reduces wear, prevents corrosion, and extends service life by automatically and precisely lubricating the elevator wire ropes, while also reducing manual maintenance costs. In existing technologies, the oil brushes used for wire rope lubrication wear down over time, and these brushes are often fixed or bolted, making disassembly complex and inflexible. Utility Model Content

[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figure 1 , Figure 2 and Figure 3An embodiment of this utility model provides an automatic lubrication device for elevator wire ropes, comprising a connecting pipe 2 3, an oil supply pipe 4 fixedly connected inside the connecting pipe 2 3, a support ring 5 fixedly connected to the outer wall of the oil supply pipe 4, a support shell 6 rotatably connected to the outer wall of the support ring 5, an oil supply brush 7 provided on the outer wall of the support shell 6, a clamping block 8 clamped to the outer wall of the connecting pipe 2 3, a fixing column 9 fixedly connected to the outer wall of the clamping block 8, a support sleeve 12 slidably connected to the outer wall of the fixing column 9, a spring 10 sleeved on the outer wall of the fixing column 9, one end of the spring 10 fixedly connected to the outer wall of the clamping block 8, the other end of the spring 10 fixedly connected to the outer wall of the support sleeve 12, a fixing plate 13 fixedly connected to the outer wall of the support sleeve 12, a fixing block 14 fixedly connected to the outer wall of the fixing plate 13, a slidably connected inner wall of the clamping block 8 to the outer wall of the fixing block 14, a slidably connected outer wall of the connecting pipe 2 3 to the inside of the fixing block 14, a pull ring 11 fixedly connected to the outer wall of the fixing column 9, and an oil supply component provided on the outer wall of the fixing block 14.

[0024] Specifically, connecting pipe 3 fixes the oil supply pipe 4, and support ring 5 fixes the oil supply pipe 4. Support ring 5 rotates inside support shell 6, and support shell 6 provides support for support ring 5. A rotating sealing ring is provided at the connection between support ring 5 and support shell 6 to seal and prevent lubricating oil leakage. Holes are provided inside support shell 6 to allow lubricating oil to be immersed in the oil supply brush 7. The oil supply brush 7 adheres to the outer wall of the elevator rope. When the elevator rope moves, it drives the oil supply brush 7 to rotate, thus... The lubricating oil on the surface of the oiling brush 7 is applied to the surface of the elevator rope to achieve the oiling operation. The fixing block 14 provides support and limits the offset of the connecting pipe 3. The outer wall of the fixing block 14 is provided with a limit strip, which also provides support and limits the offset of the clamping block 8, so that the clamping block 8 can only move on the outer wall of the limit strip of the fixing block 14. The fixing block 14 has a fixing effect on the fixing plate 13. The fixing plate 13 has a supporting and fixing effect on the support sleeve 12, ensuring the stability of the support sleeve 12. The fixing column 9 slides on the inner wall of the support sleeve 12, and the support sleeve 12 can... The fixed post 9 is supported and has a limited offset function. The outer wall of the connecting tube 2 3 has two protruding rings, and a groove is formed between the two protruding rings. When the connecting tube 2 3 is inserted into the fixed block 14, the protruding ring near the clamping block 8 will squeeze the clamping block 8. The clamping block 8 is fixed to one end of the outer wall of the fixed post 9. After the clamping block 8 is squeezed and moved, the fixed post 9 will move at the same time and slide outward inside the support sleeve 12. By setting the spring 10 between the clamping block 8 and the support sleeve 12, the spring 10 will be squeezed when the clamping block 8 moves. After the convex ring on the side near the clamping block 8 stops pressing the clamping block 8, the spring 10 will be compressed and the resulting rebound force will cause the clamping block 8 to reset and move, thus locking between the slots of the two convex rings, clamping and limiting the displacement of the connecting pipe 2 3. The fixing post 9 has a fixing effect on the pull ring 11. By pulling the pull ring 11, the fixing post 9 can be moved, thereby causing the clamping block 8 to disengage from the slot of the connecting pipe 2 3, releasing the clamping and limiting restriction on the connecting pipe 2 3, achieving the function of quick installation and disassembly, simple operation, and easy replacement.

[0025] Reference Figure 1 and Figure 2 The oil supply assembly includes a support plate 1, the outer wall of a fixing block 14 is fixedly connected to the inner wall of the support plate 1, a load-bearing plate 15 is fixedly connected to the upper surface of the support plate 1, an oil tank 16 is fixedly connected to the upper surface of the load-bearing plate 15, a solenoid valve 17 is provided on the outer wall of the oil tank 16, the outer wall of the oil tank 16 is fixedly connected to the inside of the solenoid valve 17, one end of a connecting pipe 2 is fixedly connected to the output end of the solenoid valve 17, the other end of the connecting pipe 2 is snapped into the inside of a connecting pipe 3, and the outer wall of the connecting pipe 3 is slidably connected to the inside of the support plate 1.

[0026] Specifically, the support plate 1 has a fixed bearing seat for the fixed block 14 to ensure the stability of the fixed block 14. The support plate 1 also fixes the load-bearing plate 15, ensuring its stability. The load-bearing plate 15 fixes the oil tank 16, and the bottom of the oil tank 16 has an oil outlet pipe. The outer wall of the oil outlet pipe is fixed inside the load-bearing plate 15. The outer wall of the oil outlet pipe also fixes the solenoid valve 17. The solenoid valve 17 is existing technology and can automatically open and close the oil circuit according to a set cycle to avoid excessive or insufficient lubrication. The solenoid valve 17 is connected to the... Connector 1 2 has a fixing function and can be used for oil transportation. Connector 2 3 has a sealing ring on its inner wall. The outer wall of connector 1 2 is the same size as the inner wall of connector 2 3. Therefore, connector 1 2 is clamped to the inner wall of connector 2 3. Connector 2 3 can support connector 1 2. Lubricating oil can be transported to the inside of connector 2 3 through connector 1 2. The sealing ring can improve the sealing performance. The support plate 1 has holes inside for connector 2 3 to slide. Support plate 1 has the functions of supporting and limiting the displacement of connector 2 3.

[0027] Reference Figure 1 The support plate 1 has a sliding column 18 inside, and the outer wall of the support ring 5 is engaged with the inner wall of the sliding column 18.

[0028] Specifically, the sliding column 18 slides inside the support plate 1. The support plate 1 can support and limit the displacement of the sliding column 18. At the same time, the sliding column 18 will not slide out of the support plate 1. A groove is provided on the other side of the sliding column 18 for placing the support ring 5. The tight engagement between the support ring 5 and the groove of the sliding column 18 can support and limit the displacement of the support ring 5, and prevent the support ring 5 from rotating and getting tangled as it rotates with the support shell 6.

[0029] Reference Figure 1 and Figure 4 A cylinder 19 is fixedly connected to the inner bottom wall of the support plate 1. An inclined block 20 is fixedly installed at the output end of the cylinder 19. A limit post 21 is slidably connected to the inner wall of the inclined block 20. The outer wall of the limit post 21 is fixedly connected to the inner wall of the support plate 1. A pulley 22 is slidably connected to the outer wall of the inclined block 20. A connecting frame 23 is rotatably connected inside the pulley 22. A support column 24 is fixedly connected inside the connecting frame 23. A second spring 25 is sleeved on the outer wall of the support column 24. One end of the second spring 25 is fixedly connected to the outer wall of the connecting frame 23, and the other end of the second spring 25 is fixedly connected to the outer wall of the limit plate 26. The limit plate 26 is slidably connected to the outer wall of the support column 24. A support frame 27 is fixedly connected to the outer wall of the support column 24. The upper surface of the support frame 27 is fixedly connected to the lower surface of the sliding column 18, and the inner wall of the support frame 27 is slidably connected to the inner bottom wall of the support plate 1.

[0030] Specifically, the support plate 1 fixes the cylinder 19, which in turn drives the inclined block 20 to move. The support plate 1 also fixes the limiting post 21, which in turn supports and limits the inclined block 20, allowing it to slide only back and forth on the outer wall of the limiting post 21. One side of the inclined block 20 is angled and fits against the outer wall of the pulley 22. Therefore, when the inclined block 20 moves, the pulley 22 rotates and moves inside the connecting frame 23. The movement of the pulley 22 drives the support column 24 to move inside the limiting plate 26 via the connecting frame 23. The limiting plate 26 supports and limits the support column 24, allowing it to move only linearly back and forth. The second spring 25 is positioned between the connecting frame 23 and the limiting plate 26. When the connecting frame 23 moves, it compresses the second spring 25, allowing it to move only linearly back and forth. The spring 25 acts as a reset mechanism, restoring the connecting frame 23 to its original position. Simultaneously, the spring 25 buffers the movement of the support column 24, making its movement smoother. One end of the support column 24 is fixed inside the support frame 27. When the support column 24 moves, it drives the support frame 27 to move along the inner bottom wall of the support plate 1. The limiting strip on the inner bottom wall of the support plate 1 provides mechanical support and limits the offset of the support frame 27, ensuring it can only move forward and backward. Since the upper surface of the support frame 27 is fixed to the lower surface of the sliding column 18, the movement of the support frame 27 drives the sliding column 18 to move, causing the oiling brush 7 to adhere to the outer wall of the elevator wire rope. When oiling is no longer needed, the reset mechanism of the connecting frame 23 moves the oiling brush 7 away from the elevator wire rope. This allows for adjustment of the distance between the brush and the elevator wire rope as needed, preventing slippage caused by continuous oiling.

[0031] Working principle: When the device is needed, the second connecting tube 3 is aligned with the first connecting tube 2 and slid on the outer wall of the clamping block 8 to perform the clamping operation. When the second connecting tube 3 slides on the outer wall of the clamping block 8, it will squeeze the clamping block 8 and make it move. The movement of the clamping block 8 will cause the fixing post 9 to slide outward inside the support sleeve 12. At the same time, the clamping block 8 will squeeze the first spring 10. After the second connecting tube 3 is fitted on the outer wall of the first connecting tube 2, the sealing ring set on the inner wall of the second connecting tube 3 will make the second connecting tube 3 and the first connecting tube 2 fit tightly to ensure the seal. At this time, the clamping block 8 is no longer squeezed. The first spring 10 will use the rebound force to make the clamping block 8 return to its original position and be locked in the slot of the second connecting tube 3, which will limit the offset of the second connecting tube 3. By pulling the pull ring 11, the clamping block 8 can be disengaged from the slot of the second connecting tube 3 to achieve the contact offset limit function, thereby realizing quick installation and disassembly.

[0032] When the elevator rope needs lubrication, cylinder 19 is activated. Cylinder 19 causes the inclined block 20 to slide against the outer wall of the limiting post 21. As the inclined block 20 slides, it causes the pulley 22 to roll and be compressed. This compression of the pulley 22, via the connecting frame 23, moves the support post 24 within the limiting plate 26. The movement of the limiting plate 26 moves the support frame 27, which in turn moves the sliding post 18 within the support plate 1. This movement of the support frame 27 and the sliding post 18 then moves the support ring 5. The movement of the support ring 5 will cause the support shell 6 to move the oiling brush 7 to the elevator rope. At this time, the solenoid valve 17 is activated to supply oil. Through the support shell 6, the oil can be immersed in the interior of the oiling brush 7, so that the oiling brush 7 can roll and draw oil for lubrication as it moves with the elevator rope. This device can not only improve the flexibility of use and the efficiency of maintenance by quickly replacing and disassembling the oiling brush component, but also move the brush back and forth to adapt to the requirements of intermittent oiling, avoid slippage caused by continuous oiling, and reduce manual oiling operations.
