[0034] To keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of known functions and known components are omitted.

[0035] Example 1

[0036] Reference Appendix Figure 1 -Appendix Figure 8This embodiment provides an oil leakage detection and recovery device for a hoist, including an oil receiving tank 1 located below the oil leakage point 101 and an oil storage tank 5 located below the oil receiving tank 1. The oil storage tank 5 has a third groove 28, and an oil collection tank 3 for collecting leaked oil is slidably connected within the third groove 28. A sensor 4 is installed inside the oil collection tank 3. The oil receiving tank 1 and the oil collection tank 3 are connected by a guide pipe 2, and the oil receiving tank 1 is fixed to a frame 102.

The oil tank 6 and the oil storage tank 5 each have a first connecting groove 26 on both sides, which communicates with the oil tank 6. The oil storage tank 5 has a second connecting groove 27 that communicates with the third groove 28. The second connecting groove 27 communicates with the two first connecting grooves 26. The oil storage tank 5 is equipped with a set of oil scraping components, which are used to scrape the leaking oil in the oil tank 6 into the two first connecting grooves 26.

The eccentric setting of the funnel makes the volume of the side closer to the oil leak 101 smaller, so as to avoid affecting the other structures of the hoist.

[0038] The inner wall of the guide pipe 2 is provided with a protrusion 21, and the lower end of the oil tank 1 is provided with a slot 11 for accommodating the protrusion 21.

[0043] In one aspect of this embodiment, such as Figures 2-6 As shown, the turbulence assembly includes a second rotating shaft 29 rotatably connected within the second connecting groove 27. Two cams 30 are fixedly connected to the circumferential surface of the second rotating shaft 29. The side ends of the two cams 30 are intermittently in contact with the bottom end of the second filter plate 33. Springs 32 are fixedly connected to the four corners of the top of the second filter plate 33. The four springs 32 are fixedly connected within the fourth groove 39. A drive motor 10 is fixedly connected to the side end of the oil tank 1. The drive motor 10 is connected to the second rotating shaft 29 via a coupling.

[0044] In one aspect of this embodiment, such as Figures 2-6 As shown, the oil scraping assembly includes a connecting plate 8 slidably connected to the top of the oil tank 5. An oil scraper 7 is fixedly connected to the bottom end of the connecting plate 8. A connecting rod 9 is fixedly connected to the side end of the connecting plate 8. A first drive rack 38 is fixedly connected to the bottom end of the connecting rod 9. A first rotating shaft 16 is rotatably connected to the side end of the oil tank 5. A half-tooth gear 17 that meshes with the first drive rack 38 is fixedly connected to the circumferential surface of the first rotating shaft 16. A fixing plate 19 is fixedly connected to the surface of the half-tooth gear 17. A sliding groove 20 is provided in the fixing plate 19. A second rotating shaft 29 moves outward through the side end of the oil tank 5 and extends outward. A rotating rod 37 is fixedly connected to the side end of the second rotating shaft 29. A slider 18 is fixedly connected to the side end of the rotating rod 37. The slider 18 is slidably connected in the sliding groove 20.

[0045] In another aspect of this embodiment, such as Figures 2-6As shown, each cleaning assembly includes a first groove 36 at the top of the oil tank 5. A reciprocating screw 12 is rotatably connected within the first groove 36, and a threaded plate 13 is slidably connected within the first groove 36. The threaded plate 13 is threaded to the circumferential surface of the reciprocating screw 12. The reciprocating screw 12 moves outward through the side end of the oil tank 5 and extends outward. A first gear 35 is fixedly connected to the circumferential surface of the reciprocating screw 12. A second drive rack 34 meshing with the first gear 35 is fixedly connected to the bottom end of the connecting rod 9. A connecting block 23 is fixedly connected to the side end of the threaded plate 13, and a cleaning brush 24 in contact with the first filter screen 25 is fixedly connected to the bottom end of the connecting block 23. Second grooves 14 are provided on both sides of the oil tank 5. Waste collection boxes 15 for holding miscellaneous items are slidably connected within the second groove 14; hydraulic oil flows through the guide pipe 2 to the top of the oil collection tank 3 and drips into the oil storage tank 6. The drive motor 10 is started to drive the second rotating shaft 29 to rotate, which in turn drives the rotating rod 37 to rotate, which in turn drives the slider 18 to perform circular motion. The slider 18 slides within the sliding groove 20 during its circular motion, thereby driving the fixed plate 19 to swing around the first rotating shaft 16. The swinging of the fixed plate 19 drives the first rotating shaft 16 to rotate, which in turn drives the half-gear 17 to swing, which in turn drives the first drive rack 38 to perform reciprocating linear motion. The connecting rod 9 drives the connecting plate 8 to move linearly back and forth. The connecting plate 8 drives the oil scraper 7 to move linearly back and forth within the oil storage tank 6. The oil scraper 7 moves within the oil storage tank 6, scraping the leaking oil that drips into the oil storage tank 6 into the two first connecting grooves 26. After being filtered by the first filter screen 25, the first drive rack 38 drives the second drive rack 34 to move linearly back and forth. The second drive rack 34 drives the first gear 35 to rotate reciprocally. When the first gear 35 rotates reciprocally, it drives the reciprocating screw 12 to rotate reciprocally. When the reciprocating screw 12 rotates reciprocally, it drives the threaded plate 13 to move linearly back and forth within the slot 11. The threaded plate 13 drives the connecting block 23 and the cleaning brush 24 to move forward. The cleaning brush 24 moves back and forth, causing the first filter screen 25 to move on its surface, thus cleaning the surface of the first filter screen 25. The hydraulic oil falling in the first connecting groove 26 falls into the second connecting groove 27, and after being filtered again by the second filter plate 33, it falls into the oil collection tank 3. The second rotating shaft 29 rotates, causing the cam 30 to rotate. When the cam 30 rotates, it squeezes the bottom end of the second filter plate 33, causing the second filter plate 33 to move upward. After the second filter plate 33 moves upward, when the side end of the cam 30 leaves the bottom end of the second filter plate 33, the elasticity of the spring 32 pushes the second filter plate 33 downward, thereby agitating the second filter plate 33 and preventing it from being blocked.

[0046] Its working principle is as follows: When the hydraulic cylinder leaks oil, the leaking oil is guided into the guide pipe 2 through the oil receiving tank 1. The hydraulic oil flows through the guide pipe 2 to the top of the oil collecting tank 3 and drips into the oil storage tank 6. The drive motor 10 is started to drive the second rotating shaft 29 to rotate. The rotation of the second rotating shaft 29 drives the rotating rod 37 to rotate. The rotation of the rotating rod 37 drives the slider 18 to perform circular motion. When the slider 18 performs circular motion, it slides in the sliding groove 20. The sliding of the slider 18 drives the fixed plate 19 to swing around the first rotating shaft 16. The swing of the fixed plate 19 drives the first rotating shaft 16 to rotate. A rotating shaft 16 drives a half-gear 17 to oscillate. The oscillation of the half-gear 17 drives a first drive rack 38 to reciprocate linearly. The first drive rack 38 drives a connecting rod 9, which in turn drives a connecting plate 8 to reciprocate linearly. The connecting plate 8 drives an oil scraper 7 to reciprocate linearly within an oil storage tank 6. The oil scraper 7 scrapes the leaking oil dripping into the oil storage tank 6 into two first connecting grooves 26, where it is filtered by a first filter screen 25. Simultaneously, the first drive rack 38 drives a second drive rack 34 to reciprocate linearly. 4 drives the first gear 35 to reciprocate, which in turn drives the reciprocating screw 12 to reciprocate. The reciprocating screw 12, in turn, drives the threaded plate 13 to move linearly back and forth within the first groove 36. The threaded plate 13 drives the connecting block 23 and the cleaning brush 24 to reciprocate. The cleaning brush 24 drives the first filter screen 25 to move across its surface, thus cleaning the surface of the first filter screen 25. The hydraulic oil falling from the first connecting groove 26 falls into the second connecting groove 27, where it is further filtered by the second filter plate 33. The oil flows into the oil collection tank 3. The second rotating shaft 29 rotates, driving the cam 30 to rotate. When the cam 30 rotates, it squeezes the bottom end of the second filter plate 33, causing the second filter plate 33 to move upward. After the second filter plate 33 moves upward, when the side end of the cam 30 leaves the bottom end of the second filter plate 33, the elasticity of the spring 32 pushes the second filter plate 33 downward, thereby shaking the second filter plate 33 and preventing it from being blocked. When the hydraulic oil flows to the bottom sensing area 31 of the oil collection tank 3, the sensor 4 detects the hydraulic oil and issues an alarm to notify the worker to perform equipment maintenance.
