In order to ensure the surface quality of the elevator guide rail, it is generally necessary to remove rust from the non-metallic surfaces of the elevator guide rail (i.e., the upper and lower sides of the fixed arm, and the left and right sides of the transition section of the guide arm).

The utility model can conveniently disassemble and replace the sandpaper on the mounting plate through the mutual cooperation of the mounting plate, the fixed block, the pressure block, the spring rod and the transmission component, so there is no need to replace a new rust removal device, thereby effectively improving the practicality of the device.

[0004] In the process of implementing this application, it was found that the technology has the following problems: the existing elevator guide rail maintenance rust removal devices are mostly manually operated by staff to clean the rust on the outer surface of the guide rail during use, but the space in the elevator shaft is small and the safety protection measures increase the movement time of the staff, so that subsequent staff need to spend a long time when operating the device to clean the outer wall of the guide rail, thereby reducing the practicality of the device.

[0005] For this reason, a rust removal device for elevator guide rail maintenance is proposed. Utility Model Content

[0006] The purpose of the present utility model is to solve the problem that most of the existing rust removal devices for elevator guide rails are manually controlled by staff to clean the rust on the outer surface of the guide rails during use. However, the space in the elevator shaft is narrow and the safety protection measures increase the moving time of the staff, resulting in a long time consumption for the subsequent staff to operate the device to clean the outer wall of the guide rails. The present utility model provides a rust removal device for elevator guide rail maintenance.

[0007] The present utility model specifically adopts the following technical solutions to achieve the above purpose:

[0009] Furthermore, the two cleaning mechanisms each include a base, the two bases are respectively installed on the upper and lower surfaces of the elevator body, a groove is formed on the side of the base away from the elevator body, through holes are formed on the left and right inner walls of the groove of the base, a bidirectional threaded rod is rotatably connected inside the two through holes of the base, a motor is installed on the left side of the base, the output shaft of the motor is installed on the left side of the bidirectional threaded rod, two L-shaped connecting plates are threadedly connected to the outer threads of the bidirectional threaded rod, clamping grooves are formed on the opposite sides of the two L-shaped connecting plates, fixing plates are inserted into the clamping grooves inside the two L-shaped connecting plates, V-shaped rust removal blocks are installed on the inner walls of the two fixing plates, threaded holes are formed on the sides of the two L-shaped connecting plates and the two fixing plates away from the elevator body, bolts are threadedly connected to the inner threads of the two L-shaped connecting plates, the outer threads of the two bolts respectively pass through the threaded holes inside the two L-shaped connecting plates and are connected to the threaded holes inside the two fixing plates, the inner walls of the two V-shaped rust removal blocks are respectively attached to the outer surfaces of the guide rails on the left and right sides of the elevator body, and a control panel is arranged on the front of the base, and an electrical connection is made between the control panel and the control end of the motor.

[0010] Furthermore, the positions of the two cleaning mechanisms are respectively set outside the moving paths of the driving mechanisms at the outer ends of the elevator body.

[0011] Furthermore, both sets of the limiting mechanisms each include two sets of sliders. Slots are formed on the front surfaces of the four L-shaped connecting plates. The four sliders are respectively slidably connected inside the slots of the four L-shaped connecting plates. L-shaped connecting rods are arranged on the front surfaces of the four sliders. The sides of the four L-shaped connecting rods close to the elevator body are respectively installed on the upper and lower surfaces of the elevator body.

[0012] Furthermore, both sets of the scraping mechanisms each include two sets of L-shaped fixing plates. The four L-shaped fixing plates are respectively installed on the sides of the four L-shaped connecting plates away from the elevator body. V-shaped grooves are formed on the sides of the four L-shaped fixing plates away from the adjacent set of bidirectional threaded rods. V-shaped scraping plates are arranged on the sides of the four L-shaped fixing plates away from the elevator body. The inner walls of the four V-shaped scraping plates are respectively parallel to the inner walls of the adjacent set of L-shaped fixing plates. The inner walls of the V-shaped grooves of the four L-shaped fixing plates respectively abut against the outer surfaces of the left and right guide rails of the elevator body.

[0013] Furthermore, both sets of the protection mechanisms each include protection plates. The four protection plates are symmetrically installed on the sides of the two bases away from the elevator body. Grooves are formed on the sides of the four protection plates away from the elevator body. Sealing gaskets are arranged inside the grooves of the four protection plates. The sides of the four sealing gaskets away from the elevator body respectively abut against the inner walls of the sides of the four L-shaped connecting plates away from the elevator body. The positions of the four protection plates are symmetrically distributed on the left and right sides of the two bidirectional threaded rods.

[0014] The beneficial effects of the present utility model are as follows:

When the elevator body ascends and descends subsequently, the two V-shaped rust-removing blocks inside the two cleaning mechanisms are driven to frictionally scrape the rust adhered to the outer surfaces of the elevator body guide rails. Thus, the cleaning mechanisms automatically complete rust removal of the elevator body guide rails during use, reducing the labor consumed by subsequent workers when operating the device to remove rust from the elevator body guide rails. Therefore, the practicability of the device is improved; by rotating the bolt to remove the bolt from the threaded holes of the adjacent L-shaped connecting plate and fixing plate, and then pulling the fixing plate to drive the V-shaped rust-removing block to move, the fixing plate and the V-shaped rust-removing block can be separately disassembled when damaged in use, reducing the maintenance cost consumed when the subsequent cleaning mechanism is damaged. Therefore, the practicability of the device is improved.

[0016] In the present utility model, the inner walls of the V-shaped grooves of the four groups of L-shaped fixing plates are respectively abutted against the outer surfaces of the guide rails on the left and right sides of the elevator body, and then the four groups of L-shaped fixing plates are respectively arranged on one side of the two cleaning mechanisms away from the elevator body, so that when the subsequent staff drives the elevator body to drive the two cleaning mechanisms to clean the outer wall of the guide rail of the elevator body, the four V-shaped scraping plates pre-scrape the larger foreign objects accumulated at the outer ends of the guide rails of the elevator body, thereby minimizing the damage caused by the collision between the four V-shaped rust-removing blocks and the larger foreign objects attached to the outer ends of the guide rails of the elevator body during the movement of the subsequent two cleaning mechanisms. Therefore, the number of times of regularly replacing the V-shaped rust-removing blocks by the subsequent staff is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] As Figures 1 to 4 shown, a rust removal device for elevator guide rail maintenance includes an elevator body 1. Cleaning mechanisms 2 for cleaning the guide rails on the left and right sides of the elevator body 1 are provided on both the upper and lower surfaces of the elevator body 1. Protection mechanisms 3 are provided inside both groups of cleaning mechanisms 2. Scraping mechanisms 5 are installed on the sides of both groups of cleaning mechanisms 2 away from the elevator body 1. Slots are formed on the fronts of both groups of cleaning mechanisms 2. Limiting mechanisms 4 are slidably connected inside the slots of both groups of cleaning mechanisms 2. One side of the two adjacent limiting mechanisms 4 is installed on the upper and lower surfaces of the elevator body 1. Specifically, by starting the two cleaning mechanisms 2, the cleaning devices on the left and right sides of the two cleaning mechanisms 2 are respectively abutted against the outer walls of the guide rails on the left and right sides of the elevator body 1, so that during the subsequent ascending and descending processes of the elevator body 1, the two cleaning mechanisms 2 are driven to scrape off the rust adhering to the outer surfaces of the guide rails of the elevator body 1 by friction. Thus, during the use of the cleaning mechanisms 2, the rust removal of the guide rails of the elevator body 1 is automatically completed, thereby reducing the labor consumption of the subsequent staff when operating the device to remove rust from the guide rails of the elevator body 1, and therefore improving the practicability of the device.

[0027] As Figures 1 to 4As shown in the figure, the two sets of cleaning mechanisms 2 both include a base 201. The two bases 201 are respectively installed on the upper and lower surfaces of the elevator body 1. A groove is formed on the side of the base 201 away from the elevator body 1. Through holes are formed on the inner walls on the left and right sides of the groove of the base 201. A bidirectional threaded rod 204 is rotatably connected inside the two through holes of the base 201. A motor 205 is installed on the left side of the base 201. The output shaft of the motor 205 is installed on the left side of the bidirectional threaded rod 204. Two sets of L-shaped connecting plates 202 are threadedly connected to the outer threads of the bidirectional threaded rod 204. Card slots are formed on the opposite sides of the two sets of L-shaped connecting plates 202. Fixing plates 203 are inserted into the card slots inside the two sets of L-shaped connecting plates 202. V-shaped rust removal blocks 208 are installed on the inner walls of the two fixing plates 203. Threaded holes are formed on the sides of the two sets of L-shaped connecting plates 202 and the two fixing plates 203 away from the elevator body 1. Bolts 207 are threadedly connected to the inner threads of the two sets of L-shaped connecting plates 202. The outer threads of the two bolts 207 respectively pass through the threaded holes inside the two sets of L-shaped connecting plates 202 and are connected to the threaded holes inside the two fixing plates 203. The inner walls of the two V-shaped rust removal blocks 208 are respectively attached to the outer surfaces of the left and right guide rails of the elevator body 1. A control panel 206 is arranged on the front of the base 201. An electrical connection is made between the control panel 206 and the control end of the motor 205;

[0028] Specifically, by controlling the motor 205 to start the bidirectional threaded rod 204 to drive the two V-shaped rust removal blocks 208 inside a single set of cleaning mechanism 2 to move, and attaching the inner walls of the two V-shaped rust removal blocks 208 to the outer surfaces of the left and right guide rails of the elevator body 1 respectively, so that during the subsequent ascending and descending processes of the elevator body 1, the two V-shaped rust removal blocks 208 inside the two sets of cleaning mechanisms 2 drive to frictionally scrape the rust attached to the outer surfaces of the guide rails of the elevator body 1. Thus, during the use of the cleaning mechanism 2, the rust removal of the guide rails of the elevator body 1 is automatically completed, thereby reducing the labor consumption of subsequent workers when operating the device to remove rust from the guide rails of the elevator body 1. Therefore, the practicability of the device is improved; by rotating the bolt 207 to remove the bolt 207 from the threaded holes inside an adjacent set of L-shaped connecting plate 202 and the fixing plate 203, and then pulling the fixing plate 203 to drive the V-shaped rust removal block 208 to move, the fixing plate 203 and the V-shaped rust removal block 208 can be separately disassembled when damaged during use, thereby reducing the maintenance cost consumed when the subsequent cleaning mechanism 2 is damaged. Therefore, the practicability of the device is improved.

[0029] At the same time, by arranging the positions of the two sets of cleaning mechanisms 2 on the upper and lower sides of the elevator body 1 respectively, during the subsequent start of the elevator body 1 for lifting and lowering, the two sets of cleaning mechanisms 2 are driven to clean the entire section of the outer guide rails of the elevator body 1, and during the subsequent movement of the two sets of cleaning mechanisms 2, the overlapping areas are rust-removed and cleaned multiple times, thereby improving the cleaning efficiency of the subsequent device.

[0030] As Figure 1 and Figure 2 shown, the positions of the two sets of cleaning mechanisms 2 are respectively set outside the moving path of the driving mechanism at the outer end of the elevator body 1; specifically, by setting the positions of the two sets of cleaning mechanisms 2 outside the moving path of the driving mechanism at the outer end of the elevator body 1, subsequent influence on the normal use of the elevator body 1 during the use of the two sets of cleaning mechanisms 2 can be minimized.

[0031] As Figure 3 and Figure 4 shown, the two sets of limiting mechanisms 4 both include two sets of sliders 401. Slots are formed on the front surfaces of the four L-shaped connecting plates 202. The four sliders 401 are respectively slidably connected inside the slots of the four L-shaped connecting plates 202. L-shaped connecting rods 402 are arranged on the front surfaces of the four sliders 401. One sides of the four L-shaped connecting rods 402 close to the elevator body 1 are respectively installed on the upper and lower surfaces of the elevator body 1; specifically, by respectively installing one sides of the four L-shaped connecting rods 402 close to the elevator body 1 on the upper and lower surfaces of the elevator body 1, and then respectively slidably connecting the four sliders 401 inside the slots of the four L-shaped connecting plates 202, the moving positions of the four L-shaped connecting plates 202 during use are restricted by the four sets of limiting mechanisms 4, so that subsequent deviation of the positions of the four L-shaped connecting plates 202 during use, which may cause collision and damage between the four V-shaped rust removal blocks 208 and the left and right side guide rails of the elevator body 1, can be minimized.

[0032] As Figures 1 to 4 shown, the two sets of scraping mechanisms 5 both include two sets of L-shaped fixing plates 501. The four L-shaped fixing plates 501 are respectively installed on one sides of the four L-shaped connecting plates 202 away from the elevator body 1. V-shaped grooves are formed on one sides of the four L-shaped fixing plates 501 away from the adjacent one-way threaded rods 204. V-shaped scraping plates 502 are arranged on one sides of the four L-shaped fixing plates 501 away from the elevator body 1. The inner walls of the four V-shaped scraping plates 502 are respectively parallel to the inner walls of the adjacent one set of L-shaped fixing plates 501. The inner walls of the V-shaped grooves of the four L-shaped fixing plates 501 respectively abut against the outer surfaces of the left and right side guide rails of the elevator body 1; specifically, by respectively abutting the inner walls of the V-shaped grooves of the four L-shaped fixing plates 501 against the outer surfaces of the left and right side guide rails of the elevator body 1, and then respectively arranging the four L-shaped fixing plates 501 on one sides of the two sets of cleaning mechanisms 2 away from the elevator body 1, when subsequent staff drive the elevator body 1 to drive the two sets of cleaning mechanisms 2 to clean the outer walls of the guide rails of the elevator body 1, the four V-shaped scraping plates 502 can pre-scrape larger foreign matters accumulated on the outer ends of the guide rails of the elevator body 1, so that subsequent collision and damage between the four V-shaped rust removal blocks 208 and larger foreign matters attached to the outer ends of the guide rails of the elevator body 1 during the movement of the two sets of cleaning mechanisms 2 can be minimized, and thus the subsequent replacement frequency of the V-shaped rust removal blocks 208 by the staff is reduced.

[0033] As Figure 1 、 Figure 3 and Figure 4 shown, the two sets of protection mechanisms 3 both include protection plates 301. The four protection plates 301 are symmetrically installed on one side of the two bases 201 away from the elevator body 1. Grooves are formed on the sides of the four protection plates 301 away from the elevator body 1. Sealing gaskets 302 are arranged inside the grooves of the four protection plates 301. The sides of the four sealing gaskets 302 away from the elevator body 1 respectively abut against the inner walls of the four L-shaped connecting plates 202 on the side away from the elevator body 1. The positions of the four protection plates 301 are symmetrically distributed on the left and right sides of the two bidirectional threaded rods 204. Specifically, since the positions of the four protection plates 301 are symmetrically distributed on the left and right sides of the two bidirectional threaded rods 204, the four protection plates 301 shield the left and right sides of the upper ends of the two bidirectional threaded rods 204. Then, since the sides of the four sealing gaskets 302 away from the elevator body 1 respectively abut against the inner walls of the four L-shaped connecting plates 202 on the side away from the elevator body 1, it is possible to prevent the metal chips generated by the subsequent grinding of the guide rails by the two cleaning mechanisms 2 from splashing into the grooves of the two bases 201, which may cause the bidirectional threaded rods 204 inside the grooves of the two bases 201 to fail to rotate normally.

[0034] In summary: By controlling the motor 205 to start the bidirectional threaded rod 204 to drive the two V-shaped rust removal blocks 208 inside a single cleaning mechanism 2 to move, the inner walls of the two V-shaped rust removal blocks 208 are respectively attached to the outer surfaces of the guide rails on the left and right sides of the elevator body 1. When the elevator body 1 rises and falls subsequently, the two V-shaped rust removal blocks 208 inside the two cleaning mechanisms 2 are driven to frictionally scrape the rust attached to the outer surfaces of the guide rails of the elevator body 1. Thus, the cleaning mechanism 2 automatically completes the rust removal of the guide rails of the elevator body 1 during use. By turning the bolt 207 to remove the bolt 207 from the threaded holes of an adjacent L-shaped connecting plate 202 and the fixing plate 203, and then pulling the fixing plate 203 to drive the V-shaped rust removal block 208 to move, the fixing plate 203 and the V-shaped rust removal block 208 can be separately disassembled when they are damaged during use.

[0035] At the same time, the inner walls of the V-shaped grooves of the four groups of L-shaped fixing plates 501 are respectively in contact with the outer surfaces of the guide rails on the left and right sides of the elevator body 1, and the four groups of L-shaped fixing plates 501 are respectively arranged on the side of the two groups of cleaning mechanisms 2 away from the elevator body 1, so that when the subsequent staff drives the elevator body 1 to drive the two groups of cleaning mechanisms 2 to clean the outer walls of the guide rails of the elevator body 1, the four groups of V-shaped scrapers 502 can pre-scrape away larger foreign objects accumulated on the outer ends of the guide rails of the elevator body 1, thereby avoiding as much as possible the collision and damage of the four groups of V-shaped rust removal blocks 208 and the larger foreign objects attached to the outer ends of the guide rails of the elevator body 1 during the movement of the subsequent two groups of cleaning mechanisms 2, thereby reducing the number of regular replacements of the V-shaped rust removal blocks 208 by the subsequent staff.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model. The utility model may be subject to various changes and improvements without departing from the spirit and scope of the utility model. These changes and improvements fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
