[0004] The existing rail-type elevator can effectively prevent the lifting platform from tilting and has good safety. However, there are still certain shortcomings in the overall use process: most of the existing lifting platforms still use pull ropes to complete up and down movement. The pull ropes are exposed to the construction environment for a long time, and the surface is easily sticky with a large amount of dust and dirt and is also easily corroded. The existing technology lacks a setting for automatic cleaning or maintenance of the pull rope. After long-term use, the pull rope is prone to slip and loosen, seriously affecting the stability of the lifting platform. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the utility model provides a guide rail type lifting platform that prevents tilting. The utility model is provided with a water ring, a liquid storage ring, an air storage ring, and a brush roller, so that when the traction rope pulls the lifting platform up and down, it can not only effectively remove dust and dirt on the surface, but also perform lubrication and maintenance on the outside, effectively improving the stability and safety of the lifting platform when it moves, while reducing the maintenance time of construction personnel.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a guide rail lifting platform that prevents tilting, including a base, a support frame, a plurality of support frames are fixedly arranged at the four corners of the upper end surface of the base, and a crossbeam is connected to the top end surface of each of the adjacent support frames, and a plurality of brackets are arranged on each of the crossbeams, a wire roller is rotatably arranged in the bracket, a traction rope is wound around the outside of the wire roller, one end of the traction rope passes through the crossbeam and is connected to the lifting platform, a cleaning cylinder is arranged at the bottom of the crossbeam outside the traction rope, a liquid storage ring is arranged at the top of the cleaning cylinder, a downwardly inclined bending ring is arranged on the inner circular surface of the cleaning cylinder below the liquid storage ring, and a water-passing ring made of flexible material is connected to one end of the bending ring, and the water-passing ring and the liquid storage ring are connected to each other. The arrangement of the liquid storage ring and the water-passing ring allows the dirt on the outside of the traction rope to be effectively scraped off on the outside, so that the traction rope can be smoothly rolled up and corrosion and wear can be reduced.

[0007] Preferably, each support frame end surface is provided with a slide rail, a slider is slidably provided in the slide rail, and the outer end surface of the slider is connected to the lifting platform. The provision of the slide rail and the slider effectively ensures the stability of the lifting platform when sliding.

[0008] Preferably, a first drive motor is arranged on one end surface of the bracket, and an output end of the first drive motor is connected to an end surface of the wire roller. The arrangement of the first drive motor enables the wire roller to smoothly reel in the traction rope.

[0012] Preferably, a plurality of convex strips are arranged on the outer circumferential surface of the water-passing ring, and the arrangement of the convex strips improves the scraping and cleaning effect of the water-passing ring on the traction rope.

[0013] In summary, compared with the prior art, the beneficial effects of this solution are:

[0023] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention. Embodiment 1:

[0024] refer to Figure 1-7A guide rail lifting platform for preventing tilting includes a base 10 and a support frame 17. A plurality of support frames 17 are fixedly arranged at the four corners of the upper end surface of the base 10. A cross beam 21 is connected to the top end surfaces of two adjacent support frames 17. A plurality of brackets 14 are arranged on each cross beam 21. A wire roller 12 is rotatably arranged in the bracket 14. A traction rope 20 is wound around the outside of the wire roller 12. One end of the traction rope 20 passes through the cross beam 21 and is connected to the lifting platform 11. A cleaning cylinder 15 is arranged at the bottom of the cross beam 21 on the outside of the traction rope 20. A liquid storage ring 24 is arranged at the top of the cleaning cylinder 15. A downwardly inclined bending ring 26 is arranged on the inner circular surface of the cleaning cylinder 15 below the liquid storage ring 24. A water-passing ring 27 made of flexible material is connected to one end of the bending ring 26. The water-passing ring 27 and the liquid storage ring 24 are connected to each other.

[0025] When the lifting platform 11 needs to be lifted or lowered, multiple wire rollers 12 will rotate synchronously, so as to roll up the traction rope 20 wound on the outside thereof, thereby driving the lifting platform 11 at one end of the bottom of the traction rope 20 to move upward or downward. During the lifting and lowering process of the lifting platform 11, the traction rope 20 will also move back and forth in the cleaning cylinder 15. At this time, liquid can be poured into the liquid storage ring 24, and then the liquid storage ring 24 will pressurize the liquid and then introduce it into the water passing ring 27 through a pipe. When the water passing ring 27 is filled with enough liquid, the water passing ring 27 as a whole will expand outward, thereby contacting the outer cylindrical surface of the traction rope 20, so that when the traction rope 20 moves up and down, external dirt can be scraped off by the water passing ring 27. In this process, the bending ring 26 is also made of elastic material, which can produce a certain shaking when the outside of the traction rope 20 is cleaned, so that the water passing ring 27 produces a certain shaking, so that the outside of the traction rope 20 can be better cleaned.

[0026] refer to Figure 1 A slide rail 18 is arranged on the end surface of each support frame 17, a slider 19 is slidably arranged in the slide rail 18, and the outer end surface of the slider 19 is connected to the lifting platform 11.

[0027] During the movement of the lifting platform 11 , the lifting platform 11 will drive the slider 19 to slide in the slide rail 18 , thereby ensuring the stability of the lifting platform 11 during movement. The multiple support frames 17 can provide good support to prevent the lifting platform 11 from tilting.

[0028] refer to Figure 5 A plurality of liquid spraying ports 25 are provided on the inner circumferential surface of the liquid storage ring 24 .

[0029] The interior of the liquid storage ring 24 can be filled with cleaning liquid or lubricating oil. If it is filled with cleaning liquid, during the process of pressurizing the water-passing ring 27, the cleaning liquid can be sprayed out through the liquid spray port 25 onto the outside of the traction rope 20 to improve the cleaning effect. If it is filled with lubricating oil, the liquid spray port 25 can spray the lubricating oil, thereby lubricating the outside of the traction rope 20, so that the movement of the lifting platform 11 can be more stable.

[0030] refer to Figure 5 An air storage ring 22 is arranged on the bottom end surface of the cleaning cylinder 15, and a plurality of air injection ports 23 are evenly arranged on the inner circumferential surface of the air storage ring 22 along the circumferential direction.

[0031] During operation, high-pressure gas is filled into the gas storage ring 22, so that when the traction rope 20 moves upward, the high-pressure gas can be sprayed out of the traction rope 20 through the jet port 23, so that most of the dirt outside the traction rope 20 can be blown off first, reducing the cleaning amount of the water ring 27 and improving the cleaning quality.

[0032] refer to Figure 1 A first driving motor 13 is disposed on one end surface of the bracket 14 , and an output end of the first driving motor 13 is connected to the end surface of the line roller 12 .

[0033] When the wire roller 12 needs to rotate, the output end of the first driving motor 13 can drive the wire roller 12 to rotate, thereby driving the traction rope 20 to be retracted and released.

[0034] refer to Figure 1-2 6. Two rotating shafts 29 are rotatably arranged on both sides below the line roller 12 in the bracket 14. A brush roller 16 is arranged on the outer circumferential surface of the rotating shaft 29. A second driving motor 30 is arranged on one side of the brush roller 16 on the end surface of the bracket 14. The output end of the second driving motor 30 is connected to the rotating shaft 29.

[0035] When the traction rope 20 is about to be taken away by the wire roller 12 after passing through the cleaning cylinder 15, the output end of the second drive motor 30 can drive the rotating shaft 29 to rotate, thereby driving the brush roller 16 outside the rotating shaft 29 to rotate, so as to perform the final step of brushing on the outside of the traction rope 20, so that the outside of the traction rope 20 can be fully cleaned, thereby avoiding the accumulation of dust and dirt in the wound traction rope 20, reducing the damage of the traction rope 20, and improving the service life of the equipment. Embodiment 2:

[0036] On the basis of or different from the first embodiment, reference Figure 7 A plurality of convex strips 28 are arranged on the outer circumferential surface of the water passing ring 27 .

[0037] The provision of the convex strips 28 can effectively increase the roughness of the outer circumferential surface of the water-passing ring 27, so that the water-passing ring 27 can better scrape off the dirt on the outside of the traction rope 20, thereby improving the cleaning effect.
