Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0034] Referring to Figure 1 、 Figure 2 and Figure 4 , an embodiment provided by the present utility model: an efficient auxiliary device for elevator maintenance, comprising: a housing 1, which is the external structure of this device, on which a handle convenient for users to carry is installed. At the same time, ventilation holes for ventilation and heat dissipation are provided on both the upper and lower sides of the housing 1 to ensure the stability of the device during long-term operation. A motor 2 is fixedly connected inside the housing 1, the output end of the motor 2 is fixedly connected with a rotating rod 3, the other end of the rotating rod 3 is detachably connected with a turntable 4, a brush 5 is fixedly connected to the outside of the turntable 4. By driving the rotating rod 3 to rotate by the motor 2, the turntable 4 and the brush 5 are driven to rotate. With the high-speed rotation of the brush 5, impurities on the elevator traction cable are cleaned. And the detachable connection method enables the brush 5 to be directly replaced with the turntable 4 and the brush 5 for reuse after wear. An oil passage 6 is provided inside the turntable 4, an oil passage 7 is provided inside the rotating rod 3, and the oil passage 6 and the oil passage 7 are communicated. Lubricating oil is injected through the oil passage 7 and then flows into the oil passage 6, and then overflows onto the brush 5 through the oil passage 6. With the rotating brush 5, the lubricating oil is applied to the elevator traction cable. A sealing rotating ring 8 is rotatably connected to the outside of the rotating rod 3, and the outside of the sealing rotating ring 8 is fixedly installed on the front side of the housing 1. The rotating rod 3 is supported on the housing 1 through the sealing rotating ring 8 to ensure the stability of its rotation. At the same time, the lubricating oil can be injected into the oil passage 7 through the sealing rotating ring 8;

[0035] Referring to Figures 2 - 4 , a conveying assembly for conveying lubricating oil, which is installed on the inner bottom wall of the housing 1. The conveying assembly includes a cam 9, an oil storage box 10 and a conveying chamber 11. The cam 9 is fixedly connected to the outer periphery of the rotating rod 3 near the motor 2. By driving the cam 9 to rotate by the motor 2, the conveying assembly is driven to operate synchronously. The oil storage box 10 is fixedly connected to one side of the inner bottom wall of the housing 1. The bottom of the oil storage box 10 is provided with an openable lid for adding lubricating oil. The conveying chamber 11 is fixedly connected to the other side of the inner bottom wall of the housing 1. An oil inlet pipe 12 is communicated between the oil storage box 10 and the conveying chamber 11, and an oil outlet pipe 13 is communicated between the oil inlet pipe 12 and the sealing rotating ring 8. A driving assembly for extracting lubricating oil is installed inside the conveying chamber 11. The driving assembly extracts the lubricating oil stored inside the oil storage box 10 through the oil inlet pipe 12, and then conveys the lubricating oil to the inside of the sealing rotating ring 8 through the oil outlet pipe 13, and finally overflows onto the brush 5. A solenoid valve 14 is installed in the middle of the oil outlet pipe 13, and the solenoid valve 14 is fixedly connected to the outside of the housing 1. The addition and closing of the lubricating oil are realized by opening or closing the solenoid valve 14.

[0036] Referring to Figure 3, the driving component includes a piston 15, the outside of the piston 15 is slidably connected inside the conveying bin 11, a spring 16 is arranged at the bottom of the piston 15, and a T-shaped rod 17 is fixedly connected to the top of the piston 15. As the motor 2 continuously rotates, the cam 9 will also rotate synchronously. The rotation of the cam 9 will continuously push the T-shaped rod 17 in contact with it. When the cam 9 rotates and pushes the T-shaped rod 17 downward, at this time the T-shaped rod 17 will push the piston 15 downward, causing a negative pressure to be formed inside the conveying bin 11. At this time, the lubricating oil stored inside the oil storage box 10 can be pumped out through the oil inlet pipe 12. Similarly, the spring 16 pushes the piston 15 upward, and the lubricating oil sucked into the conveying bin 11 can be injected into the sealing rotating ring 8 through the oil outlet pipe 13 and finally overflow onto the brush 5. The outside of the T-shaped rod 17 penetrates and is slidably connected to the top of the conveying bin 11, and the top of the T-shaped rod 17 abuts against the bottom of the cam 9, so that when the cam 9 rotates, it can drive the T-shaped rod 17 to move, thereby driving the conveying component to operate. One end of the spring 16 is fixedly connected to the bottom of the piston 15, and the other end of the spring 16 is fixedly connected to the inner bottom wall of the conveying bin 11. With the elastic force of the spring 16, the lubricating oil is injected into the sealing rotating ring 8. One-way valves are installed on both sides of the oil inlet pipe 12 and the oil outlet pipe 13 close to the conveying bin 11, so that only the lubricating oil inside the oil storage box 10 can enter the oil inlet pipe 12, and only the lubricating oil inside the conveying bin 11 can be discharged into the sealing rotating ring 8 through the oil outlet pipe 13.

[0037] Referring to Figure 1 , Figure 5 and Figure 6 , a side branch 18 is fixedly connected to the outside of the housing 1, a handle 19 is slidably connected to the outside of the side branch 18, adjusting shells 20 are fixedly connected to both sides of the top of the handle 19, an adjusting rod 21 is slidably connected inside the adjusting shells 20, a slider 22 is fixedly connected to the outside of the adjusting rod 21, and a compression spring 23 is arranged between the top of the slider 22 and the inner top wall of the adjusting shell 20. Pull the adjusting rod 21 upward from the inside of the adjusting shell 20 so that the adjusting rod 21 moves upward and separates from the hole on the side branch 18. When the adjusting rod 21 separates from the hole on the side branch 18, at this time, the handle 19 and the side branch 18 are in an unlocked state. Slide the handle 19 to adjust the position of the handle 19. Then, just release the adjusting rod 21. Under the action of the compression spring 23 resetting and rebounding, it will drive the slider 22 to move downward, and then push the adjusting rod 21 downward again, so that the adjusting rod 21 is inserted into another hole on the side branch 18 to complete the locking between the side branch 18 and the handle 19. The outside of the slider 22 is slidably connected inside the adjusting shell 20, so that when the user pulls the adjusting rod 21, the adjusting rod 21 will not be pulled out of the inside of the adjusting shell 20. The bottom end of the adjusting rod 21 penetrates the handle 19 and is inserted into the side branch 18. With the cooperation of the adjusting rod 21 and multiple holes on the side branch 18, the locking between the handle 19 and the side branch 18 is realized.

[0038] Working principle: By starting the motor 2 to drive the rotating rod 3 to rotate, the rotating rod 3 will drive the turntable 4 and the brush 5 to rotate synchronously. The impurities on the elevator traction cable are removed by the rotating brush 5. Subsequently, the user opens the solenoid valve 14 to open the internal channel of the oil outlet pipe 13. As the motor 2 continues to rotate, the cam 9 will also rotate synchronously. The rotation of the cam 9 will continuously push the T-shaped rod 17 in contact with it. When the cam 9 rotates and pushes the T-shaped rod 17 downward, at this time the T-shaped rod 17 will push the piston 15 downward, causing a negative pressure to be formed inside the conveying bin 11. At this time, the lubricating oil stored in the oil storage box 10 can be pumped out through the oil inlet pipe 12. Subsequently, the cam 9 continues to rotate with the motor 2. At this time, the cam 9 and the top of the T-shaped rod 17 are separated. Under the action of the spring 16, the piston 15 will be pushed upward, increasing the pressure inside the conveying bin 11. The lubricating oil enters the internal seal ring 8 through the oil outlet pipe 13. Subsequently, the lubricating oil inside the seal ring 8 will enter the internal oil passage 6 through the oil passage 7 on the rotating rod 3. After that, the lubricating oil will overflow from the inside of the turntable 4 and mix with the brush 5. With the help of the rotating brush 5, the lubricating oil is evenly applied to the elevator traction cable. And when lubricating oil does not need to be applied, just close the solenoid valve 14 to block the internal channel of the oil outlet pipe 13. At this time, the spring 16 cannot push the piston 15 upward, and at this time the T-shaped rod 17 is at the lowest point, which will not affect the normal rotation operation of the cam 9.

[0039] The user picks up the handle 19 to pick up the device. At the same time, according to the working habit, the handle at the top of the adjusting rod 21 is toggled upward, so as to pull up the adjusting rod 21 from the inside of the adjusting shell 20, making the adjusting rod 21 move upward and separate from the hole on the side branch 18. At the same time, the adjusting rod 21 will also drive the slider 22 on its outer circumference to move upward synchronously, and the upward movement of the slider 22 will compress the compression spring 23. When the adjusting rod 21 is separated from the hole on the side branch 18, at this time, the handle 19 and the side branch 18 are in an unlocked state. At this time, the user can slide the handle 19 to adjust the position of the handle 19. After that, just release the adjusting rod 21. Under the cooperation of the compression spring 23 and gravity, it will drive the slider 22 to move downward, and then push the adjusting rod 21 downward again, so that the adjusting rod 21 is inserted into another hole on the side branch 18 to complete the locking between the side branch 18 and the handle 19.

[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 recorded 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 in the protection scope of the present invention.
