[0002] An elevator guide rail is an elevator component composed of a steel rail and a connecting plate, and is divided into a car guide rail and a counterweight guide rail. From the cross-sectional shape, it is divided into three forms: T-shaped, L-shaped and hollow. While playing a guiding role, the guide rail bears the impact force during the movement of the car and the elevator braking, the impact force during the emergency braking of the safety clamp, etc. The magnitudes of these forces are related to the load capacity and speed of the elevator. Therefore, the guide rail should be selected according to the elevator speed and load capacity.

DETAILED DESCRIPTION

[0040] Embodiment 1

[0041] like Figures 1 - 3 As shown, an automatic oiling and filming processing equipment for elevator guide rails includes a slide rail 1 and an oiling device 3. The oiling device 3 is fitted with the slide rail 1. The oiling device 3 is fixedly arranged on the top of the elevator car through a fixing plate 4. The oiling device 3 is rotatably connected with a fitting roller 7 and a cleaning roller 8 on one side of the slide rail 1. A cleaning scraper 6 is arranged above the fitting roller 7. The fitting roller 7 and the cleaning scraper 6 are elastically fitted with the slide rail 1 through a contact mechanism 5. The fitting roller 7 and the cleaning roller 8 are connected by driving. Further, the cleaning roller 8 is provided with two groups symmetrically distributed on both sides of the slide rail 1. The fitting roller 7 is arranged at one end of the cleaning roller 8. The outer end surface of the fitting roller 7 is fixedly connected with a second bevel gear 10. The cleaning roller 8 is movably provided with a first bevel gear 9 on one end of the cleaning roller 8 and the fitting roller 7.

[0042] During use, the elevator guide rails are covered with dust or the lubricating oil is oxidized due to long-term use, which leads to increased friction between the elevator and the guide rails, affecting the guide rail accuracy and the elevator operation. A fitting roller 7 is provided, and the fitting roller 7 fits with the slide rail 1 under the action of the abutment mechanism 5. When the elevator is running, the friction between the fitting roller 7 and the slide rail 1 causes the fitting roller 7 to drive the cleaning roller 8 to rotate, and the oil and dust on both sides of the slide rail 1 are cleaned by the cleaning roller 8. Abutment mechanism 5 is provided above the fitting roller 7 to clean the end of the slide rail 1 as the elevator runs, thereby cleaning the oxidized oil and dust on the surface of the slide rail 1. The streamlined device structure can effectively reduce the convenience of elevator guide rail maintenance.

[0043] like Figures 1 - 5 As shown, the abutment mechanism 5 includes a driving plate 11, an elastic member 13, an abutment plate 14, a ball 15 and a first driving rod 16. The driving plate 11 is slidably connected to the inside of the oiling device 3. The abutment plate 14 is elastically connected to the driving plate 11 through the elastic member 13. One side of the fitting roller 7 or the cleaning scraper 6 fits with the end of the abutment plate 14 facing away from the driving plate 11. The ball 15 is embedded in the abutment plate 14 and fits with the fitting roller 7. The first driving rod 16 is threadedly connected to the middle part of the driving plate 11.

[0044] Furthermore, an adjusting knob 12 is provided at one end of the first driving rod 16 away from the driving plate 11 , and the adjusting knob 12 is rotatably connected to the outer end surface of the oil coating device 3 , so that the first driving rod 16 can be easily controlled by the adjusting knob 12 .

[0045] When in use, by rotating the first driving rod 16, the driving plate 11 slides inside the oiling device 3, and then the compression between the driving plate 11 and the abutment plate 14 is controlled, so as to control the abutment plate 14 to push the cleaning scraper 6 or the bonding roller 7 to fit or disengage from the surface of the slide rail 1, and a ball 15 is provided on the side where the abutment plate 14 and the bonding roller 7 fit together, so as to reduce the friction between the abutment plate 14 and the surface of the bonding roller 7, and reduce the influence of the abutment plate 14 on the rotation of the bonding roller 7.

[0046] Embodiment 2

[0047] Based on the first embodiment, Figures 1 - 3 and Figures 5 - 6 As shown, the cleaning roller 8 includes a cleaning rod body 19 and a spiral blade 20 . The cleaning rod body 19 is rotatably embedded in the side where the oiling device 3 and the slide rail 1 are in contact. The spiral blade 20 is arranged around the outer end surface of the cleaning rod body 19 .

[0048] Furthermore, the first bevel gear 9 is fixedly connected with a spline shaft 32. A spline groove 25 adapted to the spline shaft 32 is provided inside the cleaning rod main body 19. The spline shaft 32 is slidably inserted into the spline groove 25. Through the spline shaft 32 and the spline groove 25, the first bevel gear 9 can move along with the laminating roller 7 and slide inside the spline groove 25 while maintaining the driving effect on the cleaning rod main body 19.

[0049] During use, in the case of traditional cleaning rollers, after long-term use, most of the oil and dust adhere to the surface of the cleaning roller 8, resulting in a decline in the cleaning effect. By providing the cleaning rod main body 19, the cleaning rod main body 19 drives the spiral blade 20 to rotate while rotating. The spiral blade 20 rotates autonomously as the elevator descends, thereby pushing sundries such as dust on the side end face of the slide rail 1 to the end of the slide rail 1 and synchronously cleaning them through the movement of the cleaning scraper 6, thus greatly improving the cleaning effect on the slide rail 1 and reducing the maintenance frequency of the device.

[0050] As Figures 1 - 3 and Figures 5 - 9 As shown, a cavity 28 is formed inside the cleaning rod main body 19. A sealed sleeve 24 is attached to the inner wall of the cavity 28. An oil seepage hole 18 is formed at one end of the spiral blade 20 away from the cleaning rod main body 19. The oil seepage hole 18 extends through to the inside of the cavity 28. The sealed sleeve 24 is provided with a through hole adapted to the oil seepage hole 18.

[0051] As Figures 1 - 3 、 Figures 5 - 9 and Figure 11 As shown, one end of the cleaning rod main body 19 away from the first bevel gear 9 is rotatably connected with a one-way rotating rod 17 that drives the sealed sleeve 24 to move inside the cavity 28. The one-way rotating rod 17 rotates in one direction. The sealed sleeve 24 is elastically embedded inside the cavity 28. The one-way rotating rod 17 extends through to the inside of the sealed sleeve 24, and the one-way rotating rod 17 is threadedly engaged with the sealed sleeve 24.

[0052] Furthermore, the threading is partially provided on the surface of the one-way rotating rod 17.

[0053] When in use, after the contaminated oil is removed, both sides of the slide rail 1 need to be oiled to reduce friction, and then a cavity 28 is provided, in which oil is stored, and the cleaning scraper 6 and the fitting roller 7 are controlled by the abutment mechanism 5 to fit together so that the elevator enters a maintenance state. The elevator falls from the top and the fitting roller 7 drives the cleaning rod body 19 to rotate and combines with the cleaning scraper 6 so that the device can effectively clean the contaminants on the surface of the slide rail 1 when falling. When the elevator goes up from the bottom, the cleaning roller 8 reverses. At this time, due to the one-way card of the one-way rotating rod 17 and the one-way rotating rod 17 cannot rotate, and at the same time, due to the one-way rotating rod 17 and the sealed casing 24 threads are engaged, so that the sealed sleeve 24 moves inside the cavity 28, so that the through hole of the sealed sleeve 24 is connected with the oil seepage hole 18. At this time, as the cleaning rod body 19 rotates, the oil inside the cavity 28 seeps out to the end of the spiral blade 20 through the oil seepage hole 18 under the action of centrifugal force, and is evenly applied to both sides of the side end surface of the slide rail 1 through the rotation of the cleaning rod body 19, and is evenly applied to the side end surface of the slide rail 1 as the elevator goes up. When the elevator stops running or goes down, the sealed sleeve 24 will drive the one-way rotating rod 17 to rotate and reset under the action of elastic force, so that the oil seepage hole 18 is disconnected, thereby preventing pollutants from entering the cavity 28.

[0054] like Figures 1 - 3 and Figures 5 - 14 As shown, the side end surface of the cleaning rod body 19 that is in contact with the first bevel gear 9 is provided with a communication port 33 that is connected to the cavity 28 , and the oiling device 3 has an oil storage chamber 21 inside, which is connected to the communication port 33 .

[0055] Furthermore, rotating bearings are provided on both sides of the connecting port 33. When the cleaning rod body 19 is rotatably connected to the oil coating device 3 through the rotating shaft groove, both sides of the connecting port 33 are sealed. A guide port 34 extending to communicate with the connecting port 33 is provided at the bottom of the oil storage chamber 21, and the upper end surface of the oil storage chamber 21 is connected to the oil filling hole 2.

[0056] When in use, the cavity 28 is connected with the oil storage cavity 21 through the connecting port 33, which solves the problem that the cavity 28 has a small volume and is difficult to oil the long track, and can avoid the problem that the oil level in the cavity 28 is lowered and the oiling effect is poor. When the elevator goes down, the closed sleeve 24 is elastically engaged with the end of the one-way rotating rod 17 of the cavity 28 away from the connecting port 33, and the connecting port 33 is closed. When the cleaning rod body 19 is reversed, the closed sleeve 24 moves to connect the connecting port 33 with the cavity 28, and the oil seepage hole 18 is also connected with the cavity 28. At this time, the oil storage cavity 21 will continuously supply liquid to the cavity 28, and apply the lubricating liquid to the surface of the slide rail 1 through the oil seepage hole 18.

[0057] like Figures 1 - 3 , Figures 5 - 9 and Figure 15As shown, the one-way rotating rod 17 includes a ratchet plate 26 and a second driving rod 27. The ratchet plate 26 is rotatably connected to the end of the cleaning rod body 19. The second driving rod 27 extends through the interior of the closed sleeve 24, and the outer end surface of the second driving rod 27 is provided with a spiral groove 39. The end of the spiral groove 39 is connected to a ring groove 38. The closed sleeve 24 is provided with a driving protrusion 42 adapted to the spiral groove 39.

[0058] Furthermore, the outer end face of the sealed sleeve 24 is fixedly connected to the limiting slide rod 40, the inner wall of the cavity 28 is provided with a slide groove adapted to the limiting slide rod 40, and the sealed sleeve 24 and the limiting slide rod 40 are penetrated to form a connecting hole 41 adapted to the oil seepage hole 18. When the sealed sleeve 24 slides toward the side of the one-way rotating rod 17, the sealed sleeve 24 is limited by the limiting slide rod 40 so that the sealed sleeve 24 and the cleaning rod body 19 rotate synchronously, and as the sealed sleeve 24 slides, the oil seepage hole 18 and the connecting hole 41 are connected.

[0059] When in use, the one-way rotating rod 17 realizes one-way drive by being provided with a ratchet disk 26. When the elevator goes down and the cleaning roller 8 is cleaning, the one-way rotating rod 17 rotates synchronously with the cleaning roller 8. When the elevator goes up, the one-way rotating rod 17 stops rotating, so that there is a rotation difference between the sealed sleeve 24 and the one-way rotating rod 17, and the sealed sleeve 24 is driven by the adaptation of the spiral groove 39 and the driving protrusion 42, so that the sealed sleeve 24 moves inside the cavity 28. When the sealed sleeve 24 moves to a suitable position, the driving protrusion 42 slides into the inside of the cavity 28, so that the position of the sealed sleeve 24 remains stable.

[0060] Embodiment 3

[0061] Based on the first and second embodiments, Figures 1 - 3 and Figures 5 - 14 As shown, the oil coating device 3 is provided with a rotating groove 35 adapted to the cleaning rod body 19, the end of the rotating groove 35 is provided with a ratchet paddle 36 engaged with the ratchet disk 26, and the bottom of the rotating groove 35 is provided with a recovery hole 37, the recovery hole 37 is connected to the recovery chamber 22, and the recovery chamber 22 is opened inside the oil coating device 3.

[0062] Furthermore, a filter plate 23 is embedded in the recovery chamber 22, and the filter plate 23 is tilted.

[0063] During use, the ratchet paddle 36 can be used to control the engaging direction of the second drive rod 27. At the same time, a recovery hole 37 is provided at the bottom of the end of the rotating groove 35. In the cleaning state, the pollutants move towards the side close to the fitting roller 7 driven by the spiral blade 20, while in the oiling state, the oil moves towards the side away from the fitting roller 7 driven by the spiral blade 20. When there is too much oil, it accumulates at the end of the rotating groove 35, and thus the recovery hole 37 is provided to introduce the accumulated oil into the interior of the recovery chamber 22 for collection. After being filtered by the filter plate 23, it can be reused, greatly improving the recovery and reuse of the oil, while reducing the oiling effect and oil loss of the device.

[0064] Working principle: During long-term use of the elevator guide rail, the surface is covered with dust or the lubricating oil oxidizes, resulting in an increase in friction between the elevator and the guide rail, affecting the accuracy of the guide rail and the operation of the elevator. By providing the fitting roller 7, the fitting roller 7 is fitted with the slide rail 1 under the action of the engaging mechanism 5. When the elevator runs, the friction force between the fitting roller 7 and the slide rail 1 causes the fitting roller 7 to drive the cleaning roller 8 to rotate, and the cleaning roller 8 cleans the oil and dust on both sides of the slide rail 1. And above the fitting roller 7, there is an engaging mechanism 5 to clean the end of the slide rail 1 as the elevator runs, so as to clean the oxidized oil, dust and other sundries on the surface of the slide rail 1. The device structure is simple and can effectively reduce the convenience of maintaining the elevator guide rail. By rotating the first drive rod 16, the drive plate 11 slides inside the oiling device 3, and then the compression amount between the drive plate 11 and the engaging plate 14 is controlled, so as to control the engaging plate 14 to push the cleaning scraper 6 or the fitting roller 7 to fit or disengage from the surface of the slide rail 1. And on the side where the engaging plate 14 is in contact with the fitting roller 7, there are balls 15 to reduce the friction between the engaging plate 14 and the surface of the fitting roller 7 and reduce the influence of the engaging plate 14 on the rotation of the fitting roller 7. In the traditional cleaning roller, during long-term use, most of the oil and dust adhere to the surface of the cleaning roller 8, resulting in a decline in the cleaning effect. By providing the cleaning rod body 19, the cleaning rod body 19 drives the spiral blade 20 to rotate while rotating. The spiral blade 20 rotates autonomously as the elevator descends, so as to push the dust and other sundries on the side end face of the slide rail 1 to the end of the slide rail 1 and synchronously clean them through the movement of the cleaning scraper 6, thus greatly improving the cleaning effect on the slide rail 1 and reducing the maintenance frequency of the device. After the contaminated oil is removed, it is necessary to oil both sides of the slide rail 1 to reduce friction. Then, by providing a cavity 28, the cavity 28 stores oil. By controlling the engaging mechanism 5 to make the cleaning scraper 6 and the fitting roller 7 fit, the elevator enters the maintenance state. The elevator falls from the top, drives the cleaning rod body 19 to rotate through the fitting roller 7 and combines with the cleaning scraper 6, so that the device can effectively clean the pollutants on the surface of the slide rail 1 when falling.

[0065] When the elevator ascends from the bottom, the cleaning roller 8 rotates in reverse. At this time, due to the one-way clamping of the one-way rotating rod 17 and the fact that the one-way rotating rod 17 cannot rotate at this time, and since the one-way rotating rod 17 is threadedly engaged with the sealed sleeve 24, the sealed sleeve 24 moves inside the cavity 28, causing the through-hole of the sealed sleeve 24 to communicate with the oil seepage hole 18. At this time, as the cleaning rod body 19 rotates, the oil liquid inside the cavity 28 seeps out to the end of the spiral blade 20 under the action of centrifugal force through the oil seepage hole 18, and is evenly smeared on both sides of the side end face of the slide rail 1 through the rotation of the cleaning rod body 19, and is evenly smeared on the side end face of the slide rail 1 as the elevator ascends. When the elevator stops running or descends, the sealed sleeve 24 will drive the one-way rotating rod 17 to rotate and reset under the action of elastic force, disconnecting the communication of the oil seepage hole 18 to prevent pollutants from entering the cavity 28. The cavity 28 is communicated with the oil storage cavity 21 through the communication port 33, solving the problem that it is difficult to achieve oiling for a long track due to the small volume of the cavity 28, and avoiding the problem of poor oiling effect caused by the decrease of the oil liquid level in the cavity 28;

[0066] When the elevator descends, the sealed sleeve 24 closes the communication port 33 while abutting against the end of the cavity 28 away from the one-way rotating rod 17 under the action of elastic force. When the cleaning rod body 19 rotates in reverse, the movement of the sealed sleeve 24 makes the communication port 33 communicate with the cavity 28 and the oil seepage hole 18 also communicate with the cavity 28. At this time, the oil storage cavity 21 will continuously supply liquid to the cavity 28, and smear the lubricating liquid on the surface of the slide rail 1 through the oil seepage hole 18. The one-way rotating rod 17 realizes one-way drive through the ratchet disc 26. When the elevator descends and the cleaning roller 8 is cleaning, the one-way rotating rod 17 rotates synchronously with the cleaning roller 8. When the elevator ascends, the one-way rotating rod 17 stops rotating, resulting in a rotational difference between the sealed sleeve 24 and the one-way rotating rod 17. Through the adaptation of the spiral groove 39 and the driving protrusion 42, the sealed sleeve 24 is driven to move inside the cavity 28. When the sealed sleeve 24 moves to the appropriate position, the driving protrusion 42 slides into the cavity 28 to keep the position of the sealed sleeve 24 stable. The ratchet dial 36 can control the clamping direction of the second driving rod 27. At the same time, a recovery hole 37 is provided at the bottom of the end of the rotating groove 35. In the cleaning state, the pollutants move towards the side close to the fitting roller 7 driven by the spiral blade 20, while in the oiling state, the oil liquid moves towards the side away from the fitting roller 7 driven by the spiral blade 20. When there is too much oil liquid, it accumulates at the end of the rotating groove 35, so the recovery hole 37 is provided to introduce the accumulated oil liquid into the recovery cavity 22 for collection. After being filtered by the filter plate 23, it can be reused, greatly improving the recovery and reuse of the oil liquid, and at the same time reducing the oiling effect and oil loss of the device.
