Description

Technical Field

[0001] This utility model relates to the field of shovel tools, and in particular to a shovel for elevator traction sheave rope grooves. Background Technology

[0002] The traction sheave is the core component of the elevator drive system, and the rope groove is the key part that enables power transmission between the traction sheave and the wire rope. During long-term elevator operation, the wire rope groove on the traction sheave easily accumulates a large amount of dust, sludge, and other impurities. These contaminants not only affect the safety and comfort of elevator operation but may also accelerate the wear of the wire rope and shorten its service life. Therefore, an elevator traction sheave rope groove scraper was developed, which is specifically designed to clean the wire rope groove on the elevator traction sheave. In actual maintenance scenarios, operators use the scraper to precisely cut and clean the rope groove, restoring it to a suitable shape and size, ensuring good friction and meshing between the traction sheave and the wire rope, thereby ensuring the safe and efficient operation of the elevator.

[0003] However, existing elevator traction sheave rope groove scrapers have certain problems in actual use. Since most existing scrapers adopt a fixed structure, the overall cutting action avoids excessive wear of the rope groove that may affect elevator operation. However, because the cutter head and handle are integrated or use a connection method that is difficult to disassemble and replace, it is impossible to replace the scraper according to the required size when dealing with rope groove repair work with different size requirements. This limits the versatility of the scraper. When encountering special size requirements, it is often necessary to replace the entire scraper, which increases maintenance costs and time costs. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an elevator traction sheave rope groove scraper, which aims to improve the problem that the scraper cannot be replaced according to the required size in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an elevator traction sheave groove scraper, comprising a handle, a fixed plate fixedly connected to the middle of the inner wall of the handle, a brushless motor fixedly connected to the top of the fixed plate, one end of the brushless motor passing through the fixed plate and fixedly connected to a first irregular toothed column, a hollow cylinder fixedly connected to the bottom of the inner wall of the handle, a sliding column slidably connected to the top of the inner wall of the hollow cylinder, a second irregular toothed column fixedly connected to the top of the sliding column, a buffer spring fixedly connected to the top of the outer wall of the second irregular toothed column, the bottom of the buffer spring being fixedly connected to the bottom of the inner wall of the handle, a threaded column fixedly connected to the bottom of the sliding column, a scraper block threadedly connected to the outer wall of the threaded column, and a cleaning and polishing mechanism provided on the top of the brushless motor.

[0006] The above technical solution involves selecting a scraper block of the required size, inserting it into a hollow cylinder, and then connecting the upper hole of the scraper block with the threaded post. By rotating the scraper block, it is firmly fixed above the sliding post. Guided by the conical groove of the sliding post, it can be better aligned during the threaded connection, preventing deviations during installation and thus preventing stripping during rotation. Then, the brushless motor is started to drive the first irregular toothed post to rotate. Due to its special inclined characteristics, the rotation pushes the second irregular toothed post to the bottom and compresses the buffer spring. When the groove on the upper part of the second irregular toothed post crosses the inclined surface above the first irregular toothed post, the buffer spring releases its compressed elastic potential energy, causing the sliding post to drive the scraper block to reset. Then, under the rotation of the brushless motor, the scraper block can reciprocate, which facilitates the cleaning of dust, sludge, and other impurities in the elevator traction sheave.

[0007] As a further description of the above technical solution:

[0008] The cleaning and polishing mechanism includes a transmission column, the bottom of which is fixedly connected to the top of the brushless motor. The top of the transmission column passes through the handle and is fixedly connected to a rotating column. Multiple cleaning columns are fixedly connected to the outer wall of the rotating column. A spiral scraper is fixedly connected to the outer wall of the rotating column. A sealing ring is fixedly connected to the top of the outer wall of the handle. A protective sleeve is provided on the outer wall of the handle, and the inner wall of the protective sleeve engages with the sealing ring.

[0009] The above technical solution works as follows: After cleaning with the scraper block, some dust, sludge, and other impurities will remain in the groove of the elevator traction sheave. At this time, the protective cover can be removed. The rotation of the brushless motor drives the transmission column to rotate. As the transmission column rotates, it drives the rotating column to rotate, which in turn drives the cleaning column and the spiral scraper on its outer side to rotate together. Under the rotation of the cleaning column, some of the remaining dust, sludge, and other impurities can be cleaned out. For stubborn adhesives, external force can be applied to make the spiral scraper contact the groove of the traction sheave. Under the rotation of the rotating column, the stubborn adhesives can be scraped off, making the cleaning more thorough. At the same time, the sealing ring can make the protective cover firmly locked on the top of the handle to prevent it from falling off accidentally.

[0010] As a further description of the above technical solution:

[0011] A battery box is fixedly connected to the top of the inner wall of the handle, and the battery box is electrically connected to the brushless motor.

[0012] The above technical solution allows the brushless motor to be powered by a battery box.

[0013] As a further description of the above technical solution:

[0014] A rubber sleeve is fixedly connected to the outer wall of the handle, and the outer wall of the rubber sleeve has multiple anti-slip grooves.

[0015] The above technical solution improves the anti-slip ability of the handle by using a rubber sleeve and further enhances the anti-slip ability of the handle by using anti-slip grooves.

[0016] As a further description of the above technical solution:

[0017] A warning sign block is fixedly connected to the bottom front side of the handle, and an inclined groove is provided on the top inner wall of the shovel block.

[0018] The above technical solution allows for the use of warning signs to indicate precautions, while the inclined grooves facilitate the easy turning over and discharging of dust, grease, and other impurities.

[0019] As a further description of the above technical solution:

[0020] A fixing block is fixedly connected to the front side of the outer wall of the hollow cylinder, and a nameplate is fixedly connected to the front side of the fixing block.

[0021] The above technical solution provides installation space for the nameplate through the fixing block, and the nameplate can record the model and factory information of the equipment.

[0022] As a further description of the above technical solution:

[0023] A notch is provided on the rear side of the outer wall of the rubber sleeve, and an arc-shaped cover plate is provided on the rear side of the outer wall of the handle, which engages with the handle.

[0024] The above technical solution allows for easy removal of the curved cover through the notch, and facilitates battery replacement inside the battery compartment through the curved cover.

[0025] As a further description of the above technical solution:

[0026] The inner wall size of the protective sleeve is the same as the outer wall size of the handle, and the length of the cleaning column is greater than the length of the spiral scraper.

[0027] The above technical solution allows the protective sleeve and handle to be the same size, which enables the protective sleeve to fit together better. The cleaning column is larger than the spiral scraper, which can perform preliminary cleaning first. For those that cannot be cleaned by sweeping, the spiral scraper can scrape them clean.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, by selecting a scraper block of appropriate size and inserting it into a hollow cylinder, the scraper block is rotated to fix its threads on the sliding column, and under the guidance of the conical groove, installation deviation is prevented. The brushless motor is started, causing the first irregular toothed column to rotate, pushing the second irregular toothed column to move downward and compressing the buffer spring. When the tooth groove passes the inclined plane, the buffer spring releases its elastic potential energy, and the sliding column drives the scraper block to reset, realizing reciprocating motion. This makes it easy to replace the appropriate scraper block to clean the dust and sludge in the elevator traction sheave.

[0030] 2. In this utility model, after removing the protective cover, the brushless motor drives the transmission column to rotate, which in turn rotates the cleaning column and the spiral scraper. The cleaning column can remove dust and impurities, while the spiral scraper removes adhesive substances. The sealing ring ensures that the protective cover is fixed on the handle to prevent it from falling off, thereby making the cleaning more thorough. Attached Figure Description

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Reference Figure 1 , Figure 4 and Figure 6 This utility model provides an embodiment of an elevator traction sheave rope groove scraper, including a handle 1. A fixed plate 3 is fixedly connected to the middle of the inner wall of the handle 1. A brushless motor 4 is fixedly connected to the top of the fixed plate 3. One end of the brushless motor 4 passes through the fixed plate 3 and is fixedly connected to a non-circular toothed column 5. A hollow cylinder 9 is fixedly connected to the bottom of the inner wall of the handle 1. A sliding column 7 is slidably connected to the top of the inner wall of the hollow cylinder 9. A non-circular toothed column 8 is fixedly connected to the top of the sliding column 7. A buffer spring 6 is fixedly connected to the top of the outer wall of the non-circular toothed column 8. The bottom of the buffer spring 6 is fixedly connected to the bottom of the inner wall of the handle 1. When the brushless motor 4 is started, it drives the non-circular toothed column 5 to rotate. Due to its special tilting characteristics, when rotating, it pushes the non-circular toothed column 8 to move to the bottom and squeezes the buffer spring 6. When the non-circular toothed column 8 is above the bottom, the non-circular toothed column 5 rotates. When the tooth groove passes over the inclined surface above the irregular tooth column 5, the buffer spring 6 will release its compressed elastic potential energy, thereby causing the sliding column 7 to drive the scraper block 10 to reset. Then, under the rotation of the brushless motor 4, the scraper block 10 can reciprocate. The bottom of the sliding column 7 is fixedly connected to the threaded column 11, and the outer wall of the threaded column 11 is threadedly connected to the scraper block 10. Select the scraper block 10 of the required size, insert it into the hollow cylinder 9, and then make the hole above it threadedly connected to the threaded column 11. By rotating the scraper block 10, the scraper block 10 is firmly fixed above the sliding column 7. Under the guidance of the conical groove of the sliding column 7, it can be better aligned when threaded, preventing deviation during installation. The top of the brushless motor 4 is provided with a cleaning and polishing mechanism 2.

[0041] Specifically, select the required size scraper block 10 and insert it into the hollow cylinder 9. Then, make the hole above it threadedly connected with the threaded post 11. By rotating the scraper block 10, the scraper block 10 is firmly fixed above the sliding post 7. Under the guidance of the conical groove of the sliding post 7, it can be better aligned during the threaded connection, preventing deviation during installation and stripping during rotation. Then, start the brushless motor 4 to drive the irregular toothed post 5 to rotate. Due to its special inclined characteristics, it will push the irregular toothed post 8 to the bottom during rotation and compress the buffer spring 6. When the tooth groove above the irregular toothed post 8 passes the inclined surface above the irregular toothed post 5, the buffer spring 6 will release its compressed elastic potential energy, thereby causing the sliding post 7 to drive the scraper block 10 to reset. Then, under the rotation of the brushless motor 4, the scraper block 10 can reciprocate, which facilitates the cleaning of dust, sludge and other impurities in the elevator traction sheave.

[0042] Reference Figure 2 , Figure 4 and Figure 5 The cleaning and polishing mechanism 2 includes a transmission column 201. The bottom of the transmission column 201 is fixedly connected to the top of the brushless motor 4. The top of the transmission column 201 passes through the handle 1 and is fixedly connected to a rotating column 202. The rotation of the brushless motor 4 drives the transmission column 201 to rotate. At this time, as the transmission column 201 rotates, it drives the rotating column 202 to rotate, which in turn drives the cleaning column 203 and the spiral scraper 204 on its outer side to rotate together. Multiple cleaning columns 203 are fixedly connected to the outer wall of the rotating column 202. Under the rotation of the cleaning column 203, some residual dust, sludge and other impurities can be cleaned out. The spiral scraper 204 is fixedly connected to the outer wall of the rotating column 202. The spiral scraper 204 can scrape off stubborn adhesives. A sealing ring 205 is fixedly connected to the top of the outer wall of the handle 1. A protective sleeve 206 is provided on the outer wall of the handle 1. The inner wall of the protective sleeve 206 is engaged with the sealing ring 205.

[0043] Specifically, after cleaning with the scraper block 10, some dust, sludge, and other impurities will remain in the groove of the elevator traction sheave. At this time, the protective cover 206 can be removed. The rotation of the brushless motor 4 drives the transmission column 201 to rotate. As the transmission column 201 rotates, it drives the rotating column 202 to rotate, which in turn drives the cleaning column 203 and the spiral scraper 204 on its outer side to rotate together. Under the rotation of the cleaning column 203, some of the remaining dust, sludge, and other impurities can be cleaned out. For stubborn adhesives, external force can be applied to make the spiral scraper 204 contact the groove of the traction sheave. Under the rotation of the rotating column 202, the stubborn adhesives can be scraped off, making the cleaning more thorough. At the same time, under the action of the sealing ring 205, the protective cover 206 can be firmly locked on the top of the handle 1 to prevent it from falling off accidentally.

[0044] Reference Figure 1 , Figure 2 and Figure 4 A battery box 12 is fixedly connected to the top of the inner wall of the handle 1. The battery box 12 is electrically connected to the brushless motor 4 and can provide power to the brushless motor 4. A rubber sleeve 14 is fixedly connected to the outer wall of the handle 1. The outer wall of the rubber sleeve 14 has multiple anti-slip grooves 15. The rubber sleeve 14 can improve the anti-slip ability when holding the handle 1, and the anti-slip grooves 15 further improve the anti-slip ability of the handle 1. A warning sign block 16 is fixedly connected to the bottom of the front side of the handle 1. The top of the inner wall of the shovel block 10 has an inclined groove 19. The warning sign block 16 can remind users of precautions when using the shovel block 10, and the inclined groove 19 can easily turn over and drop dust, sludge and other impurities.

[0045] Specifically, the battery box 12 provides power to the brushless motor 4, the rubber sleeve 14 improves the anti-slip ability when holding the handle 1, and the anti-slip groove 15 further improves the anti-slip ability of the handle 1. The warning sign block 16 can remind users of precautions when using the product, and the tilting groove 19 makes it easy for dust, sludge and other impurities to be easily turned over and fall off.

[0046] Reference Figure 1 , Figure 2 and Figure 5A fixing block 17 is fixedly connected to the front side of the outer wall of the hollow cylinder 9. A nameplate 18 is fixedly connected to the front side of the fixing block 17. The fixing block 17 provides installation space for the nameplate 18, and the nameplate 18 can record the model and factory information of the equipment. A notch 20 is opened on the rear side of the outer wall of the rubber sleeve 14. An arc-shaped cover plate 13 is provided on the rear side of the outer wall of the handle 1. The arc-shaped cover plate 13 is engaged with the handle 1. The notch 20 makes it easy to remove the arc-shaped cover plate 13. The arc-shaped cover plate 13 makes it easy to replace the battery in the battery box 12. The inner wall size of the protective sleeve 206 is the same as the outer wall size of the handle 1. The length of the cleaning column 203 is greater than the length of the spiral scraper 204. The size of the protective sleeve 206 is the same as that of the handle 1, which allows the protective sleeve 206 to be better engaged. The cleaning column 203 is larger than the spiral scraper 204, so it can perform preliminary cleaning first. For those that cannot be cleaned, the spiral scraper 204 can scrape and clean them.

[0047] Specifically, the fixing block 17 provides installation space for the nameplate 18, and the nameplate 18 can record the model and factory information of the device. The notch 20 makes it easy to remove the arc-shaped cover 13, and the arc-shaped cover 13 makes it easy to replace the battery in the battery box 12. The protective cover 206 is the same size as the handle 1, which allows the protective cover 206 to fit together better. The cleaning column 203 is larger than the spiral scraper 204, so it can perform preliminary cleaning first. For those that cannot be cleaned, the spiral scraper 204 can scrape and clean them.

[0048] Working principle: Select a scraper block 10 of appropriate size and insert it into the hollow cylinder 9, ensuring that its upper end hole is threadedly connected to the threaded post 11. By rotating the scraper block 10, it is firmly fixed to the top of the sliding post 7. Guided by the conical groove of the sliding post 7, the threaded connection can be aligned, avoiding deviations during installation and preventing stripping during rotation. Next, start the brushless motor 4 to drive the irregular toothed post 5 to rotate. Due to its unique inclined design, the irregular toothed post 8 will move to the bottom during rotation and apply pressure to the buffer spring 6. When the tooth groove of the irregular toothed post 8 passes the inclined surface of the irregular toothed post 5, the buffer spring 6 will release its stored elastic potential energy, causing the sliding post 7 to drive the scraper block 10 to reset. Under the continuous drive of the brushless motor 4, the scraper block 10 can perform reciprocating motion, which facilitates cleaning the elevator traction sheave. The cleaning mechanism 2 removes dust, sludge, and other impurities from the wheel groove of the elevator traction sheave. Even after cleaning with the scraper block 10, dust, sludge, and other impurities may still remain in the groove. In this case, the protective cover 206 can be removed, and the brushless motor 4 can be started to drive the transmission column 201 to rotate. The rotation of the transmission column 201 will drive the rotating column 202, the cleaning column 203, and the spiral scraper 204 to rotate together. The rotation of the cleaning column 203 can remove the dust, sludge, and other impurities remaining in the wheel groove. For stubborn adhesives, external force is applied to make the spiral scraper 204 contact the wheel groove of the traction sheave, and the rotation of the rotating column 202 is used to scrape off these adhesives to ensure a more thorough cleaning effect. In addition, the sealing ring 205 ensures that the protective cover 206 can be firmly fixed to the top of the handle 1 to prevent it from falling off accidentally.
