Description

Technical Field

[0001] This invention relates to the field of oil stain cleaning technology for large racks, and more particularly to an oil stain cleaning device and method for a large-module, long-stroke driven rack for vertical ship lifts. Background Technology

[0002] As a rapid passage for ships to pass under dams in large-scale water conservancy projects, the reliability of ship lifts directly affects the efficiency and safety of waterway navigation. The rack and pinion mechanism, a key transmission component of the ship lift's drive system, bears the core functions of transmitting power, achieving precise positioning of the ship compartment, and withstanding enormous loads. The meshing accuracy of the rack and pinion and the surface lubrication condition directly affect transmission efficiency, vibration and noise levels, and equipment lifespan, and are crucial elements for ensuring the stable operation of the ship lift.

[0003] Currently, ship lift racks primarily use automatic oiling systems for lubrication, with high-viscosity grease being the main lubricant. However, the ship lift's rack and pinion mechanism is an open structure, with the gears narrower than the racks. During operation, lubricating oil often accumulates on both sides of the rack. Exposed to wind and sun, this oil often drips onto the ship's interior, deck, or railings, causing environmental pollution in the Yangtze River. Regular manual cleaning is necessary, but this is difficult and labor-intensive. Traditional manual cleaning is inefficient, involves high-altitude operations, and struggles to thoroughly remove oil from complex areas such as the tooth roots and sides, leading to prolonged downtime and impacting navigation efficiency.

[0004] Currently, there is a lack of dedicated devices for cleaning oil stains from racks. Most methods rely on manual labor or general cleaning tools, resulting in incomplete cleaning, low automation, and a high risk of secondary pollution. Therefore, there is an urgent need to develop an efficient, environmentally friendly, and automated oil stain cleaning device adapted to rack structures to improve the operational safety of ship lifts, extend equipment lifespan, and reduce environmental burden, aligning with the trend of intelligent and green development in modern water conservancy projects. Summary of the Invention

[0005] To address the existing technical problems, the present invention aims to propose a large-module, long-stroke drive rack oil cleaning device and method for vertical ship lifts. This device achieves automatic cleaning of oil stains on the rack through mechanization, replacing manual cleaning. It is also an efficient, environmentally friendly, and rack-structure compatible automated oil cleaning device that can improve the operational safety of ship lifts, extend equipment life, and reduce environmental burden, aligning with the development trend of intelligent and green modern water conservancy projects.

[0006] To achieve the aforementioned technical features, the present invention aims to provide a large-module, long-stroke drive rack oil cleaning device for a vertical ship lift, comprising a frame, a guiding mechanism, an oil scraping stroke adaptation mechanism, an oil scraping mechanism, and a lifting mechanism. The frame is raised and lowered along the rack via the lifting mechanism. The guiding mechanism guides the entire device through multiple sets of guide wheels, ensuring the device always moves along the rack. The oil scraping mechanism uses a double-rotating screw to move two scraping plates simultaneously to both sides of the rack, scraping oil from multiple tooth surfaces at once. The oil scraping mechanism enters and exits its working state via the oil scraping stroke adaptation mechanism. This mechanism, driven by a worm gear lift, moves the oil scraping mechanism along a guide rail slider assembly, and multiple springs ensure the scraping plates remain in contact with the rack tooth surfaces during operation.

[0007] Preferably, the frame is assembled from a top frame, side frames, and wire rope connectors. Two sets of side frames are installed on the lower end face of the top frame, and the wire rope connectors are installed on the upper end face of the top frame. The wire rope connectors are used to quickly connect the wire ropes of the hoisting mechanism.

[0008] Preferably, forward, reverse, and lateral guide rails are respectively installed on both sides of the rack. The two sets of guiding mechanisms are respectively installed on the side frame. The guiding mechanism consists of a forward wheel set, a lateral wheel set, and a reverse wheel set. The forward wheel set is installed on the front of the frame through a forward wheel set bracket. The lateral wheel set is installed on the side of the frame through a lateral wheel set bracket. The reverse wheel set is installed on the side of the frame through a reverse wheel set bracket. The forward, lateral, and reverse wheel sets contact the forward, reverse, and lateral guide rail surfaces of the rack for guidance. The forward and lateral wheel sets can adjust the gap and contact force between the guide wheels and the corresponding guide rails to ensure accurate guidance and positioning of the guiding mechanism.

[0009] Preferably, the forward wheel assembly and the side wheel assembly adopt the same structure, both including guide wheels. The guide wheels are mounted on the guide wheel shaft via bearings, and the bearings are positioned via a cover. The guide wheel shaft is mounted on a guide frame, and the guide frame is fixedly connected to a disc spring shaft. A disc spring assembly is mounted on the disc spring shaft, and a disc spring sleeve is welded to both sides of the guide frame. The disc spring sleeve slides in contact with a sliding plate to ensure that the guide frame and the guide wheels move axially along the disc spring shaft. The sliding plate is mounted on a fixed bracket via bolts, and a support plate is mounted above the fixed bracket. The disc spring shaft passes through the center hole of the support plate and is fixed by an adjusting nut. The adjusting nut can adjust the compression of the disc spring to adjust the gap and contact force between the guide wheel and the rack guide rail.

[0010] Preferably, the oil scraping stroke adaptation mechanism includes a worm gear jack, which is driven by a motor. Both the worm gear jack and the motor are mounted on an upper support plate. Side support plates are mounted on both sides of the upper support plate. The side support plates are slidably assembled with the side slide plates via two sets of guide rail slider assemblies. The side slide plates are fixed to the lower support plate. A spring is mounted on a spring guide rod. The lower ends of the four spring guide rods are fixed to the lower support plate. The mounting holes of the worm support plate pass through the spring guide rods. A limit nut is installed on the upper end of the spring guide rods. The worm support plate can move back and forth relative to the lower support plate along the axial direction of the spring guide rods. The spring is located between the worm support plate and the lower support plate. The oil scraping stroke adaptation mechanism ensures that the oil scraping mechanism always maintains flexible adaptive contact with the direction perpendicular to the rack pitch line, achieving efficient cleaning of oil stains on the rack without damaging the tooth surface.

[0011] Preferably, the oil scraping mechanism includes a double-screw rotatably mounted between the side slide plates. The threads at the left and right ends of the double-screw have opposite directions. A synchronous pulley is mounted on one end of the double-screw, and the other synchronous pulley is mounted on the side slide plate. The two synchronous pulleys are driven by a synchronous belt. A motor drives the synchronous pulley to rotate the double-screw. Scraper supports are respectively mounted on the two ends of the threads of the double-screw. The scraper supports are guided by two sets of guide rods. Below the scraper support is a scraper adjustment seat. The back of the scraper adjustment seat is assembled with the scraper support via a guide rail slider assembly. An oil scraper is mounted on the scraper adjustment seat. Two sets of spring guide rods are installed at both ends of the plate adjustment seat. A spring is installed on the spring guide rod. The other end of the spring guide rod is installed on the limiting plate. The limiting plate is installed on the scraper support. The oil scraping mechanism is raised and lowered by the lifting mechanism. When the oil scraping mechanism enters the working state, the oil scraper on it is finely adjusted by the guide rail slider assembly and the spring to ensure that the oil scraper on it can adapt to the displacement deviation in the direction of the rack index line when the oil scraping mechanism enters the working state, ensuring that the oil scraper is always in contact with the rack tooth surface, and that the oil scraper maintains a certain pressure with the rack tooth surface during the oil scraping process.

[0012] Preferably, the mounting surface of the scraper adjustment seat is wedge-shaped, which allows the scraper to be at a certain angle to the tooth surface of the rack after installation, thereby reducing the movement resistance of the scraper during the oil cleaning process.

[0013] Preferably, the scraper blade is made of carbon fiber to ensure that the tooth surface is not damaged; the surface of the scraper blade is coated with an oleophobic coating, and the two scraper blades are arranged with a flared opening that is wider at the top and narrower at the bottom, so that the oil accumulated on the scraper blades during the oil cleaning process will slide down to the oil collection tray at the bottom by its own weight.

[0014] Preferably, the scraper blade and the scraper blade adjustment seat are quickly detachable for quick replacement of the scraper blade; the bottom of the scraper blade has the same shape as the tooth profile of the rack, ensuring that the scraper blade can simultaneously contact multiple tooth surfaces.

[0015] On the other hand, the present invention provides a method for using a large-module, long-stroke drive rack oil sludge cleaning device for a vertical ship lift, comprising the following steps: Step 1: The rack oil cleaning device is initially located at the top of the rack, which does not affect the normal operation of the ship lift. When rack oil cleaning is required, the ship lift moves to the lowest elevation, the lifting mechanism is activated, and the frame, guide mechanism, oil scraping stroke adaptation mechanism and oil scraping mechanism are lowered as a whole to a position 0.2~0.5m directly above the construction platform, ensuring that the bottom contour of the oil scraper blade coincides with the rack tooth profile. Step 2: Control the motor to slowly bring the scraper blade on the scraper mechanism into contact with the tooth surface of the rack until the spring is compressed to 1 / 3 of its natural length and then stop the machine. This ensures that the scraper blade enters the predetermined working state. During the process of the scraper blade slowly contacting the tooth surface of the rack, the scraper blade adjustment seat slides relative to the scraper blade support, so that the scraper blade adapts to the displacement deviation in the direction of the rack's index line, ensuring that the scraper blade accurately contacts multiple tooth surfaces at the same time. Step 3: Start motor two and move the scraper blade towards both ends of the rack until it is completely separated from the rack. Then stop the machine and scrape the oil stains on the tooth surface and tooth root to both ends of the rack. The oil stains will fall into the oil collection grooves on both sides under the action of gravity. Adjust the length of the scraper blade according to the situation to ensure that the oil stains on 6 to 8 tooth surfaces can be cleaned at the same time. Step 4: After the scraper blade has completely disengaged from the rack tooth surface, control motor one to raise the scraper blade back to the upper limit position, operate the lifting mechanism to raise the entire device by one working stroke, and then operate motor two to return the scraper blade to the initial scraping position. Step 5: Repeat steps 2 to 4 until the oil stains on the entire rack tooth surface are cleaned.

[0016] The present invention has the following beneficial effects: 1. This invention is a large-module long-stroke drive rack oil cleaning device for a vertical ship lift. Through three sets of guiding mechanisms, the device can accurately crawl along the rack and scrape off oil from 6 to 8 tooth surfaces at the same time, resulting in high oil cleaning efficiency.

[0017] 2. The two scraper blades on the scraper mechanism of this invention can simultaneously scrape the oil stains on the tooth surface to both ends through the double-rotating screw. The bottom shape of the scraper blade is the same as the tooth profile of the rack. The scraper blade is made of carbon fiber plate with an oleophobic coating. The two scraper blades are arranged in a funnel shape with a larger top and a smaller bottom. During operation, the oil stains accumulated on the scraper blades can slide directly into the oil receiving tray at the bottom by their own weight, which is convenient and quick.

[0018] 3. The oil scraper on the oil scraping mechanism of the present invention adapts to the displacement deviation of the oil scraper relative to the direction of the rack indexing line through the oil scraping stroke adaptation mechanism, ensuring that the oil scraper is precisely in contact with multiple tooth surfaces at the same time, and performs precise operation.

[0019] 4. The present invention can adjust the gap and contact force between the guide wheel and the rack guide rail through the forward wheel set and the side wheel set, so as to ensure the precise guidance and limiting of the guiding mechanism.

[0020] 5. This invention allows for adjustment of the compression of the disc spring by adjusting the adjusting nut, thereby adjusting the gap and contact force between the guide wheel and the rack guide rail.

[0021] 6. The present invention uses an oil scraping stroke adaptation mechanism to ensure that the oil scraping mechanism always maintains flexible adaptive contact with the direction perpendicular to the rack pitch line, thereby achieving efficient oil cleaning on the rack without damaging the tooth surface.

[0022] 7. The oil scraper of the present invention can be finely adjusted by the guide rail slider assembly two and the spring two to ensure that when the oil scraping mechanism enters the working state, the oil scraper on it can adapt to the displacement deviation in the direction of the rack index line, ensuring that the oil scraper is always in contact with the tooth surface, and the oil scraper always maintains a certain pressure with the tooth surface during the process of scraping off oil stains.

[0023] 8. The scraper blade of this invention is made of carbon fiber, ensuring that the tooth surface is not damaged. Attached Figure Description

Detailed Implementation

[0041] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0042] Example 1: See Figure 1-15 A large-module, long-stroke driven rack oil cleaning device for a vertical ship lift includes a frame 3, a guide mechanism 4, an oil scraping stroke adaptation mechanism 5, an oil scraping mechanism 6, and a lifting mechanism 7. The frame 3 is raised and lowered along the rack 1 via the lifting mechanism 7. The guide mechanism 4 guides the entire device through three sets of guide wheels, ensuring that the device can always be raised and lowered along the rack 1. The oil scraping mechanism 6 uses a double-rotating screw 601 to move two oil scraping plates 606 simultaneously to both sides of the rack 1, which can scrape oil from six tooth surfaces on the rack 1 at once. The oil scraping mechanism 6 enters and exits the working state through the oil scraping stroke adaptation mechanism 5. The oil scraping stroke adaptation mechanism 5 drives the oil scraping mechanism 6 to enter and exit along the guide rail slider assembly 509 via a worm gear lift, and four springs 609 ensure that the oil scraping plates 606 are always in contact with the tooth surfaces of the rack 1 during operation. This automated device automatically cleans oil stains from the rack, replacing manual cleaning. It is a highly efficient, environmentally friendly, and rack-and-pinion structure-compatible automated oil cleaning system that improves the safety of ship lift operations, extends equipment lifespan, and reduces environmental impact, aligning with the trend of intelligent and green development in modern water conservancy projects. During the cleaning process, the lifting mechanism 7, guided by the guide mechanism 4, moves the entire frame 3 up and down along the rack 1. After reaching a certain height, the oil scraping mechanism 6 is appropriately pressed against the outer surface of the rack 1 by the oil scraping stroke adaptation mechanism 5. Then, the oil scraping mechanism 6 is simultaneously activated, scraping away the oil stains from the outer surface of the rack 1. Furthermore, three sets of guide mechanisms allow the device to precisely crawl along the rack, simultaneously scraping oil stains from 6-8 tooth surfaces, resulting in high oil cleaning efficiency.

[0043] Furthermore, the frame 3 is assembled from a top frame 301, side frames 302, and wire rope connectors 303. The two sets of side frames 302 are installed on the lower end face of the top frame 301, and the wire rope connectors 303 are installed on the upper end face of the top frame 301. The wire rope connectors 303 are used for quick connection of the wire rope of the lifting mechanism 7. The frame 3 described above enables reliable installation of the entire oil scraping stroke adaptation mechanism 5 and the oil scraping mechanism 6.

[0044] Furthermore, forward, reverse, and lateral guide rails are respectively installed on both sides of the rack 1. Two sets of guiding mechanisms 4 are respectively mounted on the side frame 302. Each guiding mechanism 4 consists of a forward wheel set 401, a lateral wheel set 403, and a reverse wheel set 405. The forward wheel set 401 is mounted on the front of the frame 3 via a forward wheel set bracket 402. The lateral wheel set 403 is mounted on the side of the frame 3 via a lateral wheel set bracket 404. The reverse wheel set 405 is mounted on the side of the frame 3 via a reverse wheel set bracket 406. The forward wheel set 401, lateral wheel set 403, and reverse wheel set 405 respectively contact the forward, reverse, and lateral guide rail surfaces of the rack 1 for guidance. The forward wheel set 401 and lateral wheel set 403 can adjust the gap and contact force between the guide wheels and the rack 1 guide rails to ensure precise guidance and positioning of the guiding mechanism 4. The aforementioned guide mechanism 4 enables guidance during the lifting process, thereby ensuring that the frame 3 can always move smoothly and stably along the rack 1, and simultaneously achieves forward and lateral guidance to prevent tilting and jamming.

[0045] Furthermore, both the forward-facing wheel assembly 401 and the lateral wheel assembly 403 include guide wheels 4011. The guide wheels 4011 are mounted on guide wheel shafts 4013 via bearings 4019. The bearings 4019 are positioned via a cover 4012. The guide wheel shaft 4013 is mounted on a guide frame 4014. The guide frame 4014 is fixedly connected to a disc spring shaft 4018. A disc spring assembly 4016 is mounted on the disc spring shaft 4018. Disc spring sleeves 4017 are welded to both sides of the guide frame 4014. 017 slides in contact with the sliding plate 4020, ensuring that the guide frame 4014 and guide wheel 4011 move axially along the disc spring shaft 4018. The sliding plate 4020 is bolted to the fixed bracket 4021, and a support plate 4022 is installed above the fixed bracket. The disc spring shaft 4018 passes through the center hole of the support plate 4022 and is fixed by an adjusting nut 4015. The adjusting nut 4015 can adjust the compression of the disc spring, thereby adjusting the gap and contact force between the guide wheel 4011 and the rack 1 guide rail. The aforementioned forward wheel set 401 and lateral wheel set 403 ensure that a certain clamping force is maintained between the wheel and the rack 1 during the guiding process, thus ensuring smooth lifting.

[0046] Furthermore, the oil scraping stroke adaptation mechanism 5 includes a worm gear jack 501, which is driven by a motor 502. Both the worm gear jack 501 and the motor 502 are mounted on an upper support plate 503. Side support plates 504 are mounted on both sides of the upper support plate 503. The side support plates 504 are slidably assembled with side slide plates 508 via two sets of guide rail slider assemblies 509. The side slide plates 508 are fixed to a lower support plate 507. A spring 506 is mounted on the spring guide rod 510. The four... The lower end of the spring guide rod 510 is fixed to the lower support plate 507. The mounting hole of the worm gear support plate 505 passes through the spring guide rod 510. A limit nut is installed on the upper end of the spring guide rod 510. The worm gear support plate 505 can move back and forth relative to the lower support plate 507 along the axial direction of the spring guide rod 510. The spring 506 is located between the worm gear support plate 505 and the lower support plate 507. The oil scraping stroke adaptation mechanism 5 ensures that the oil scraping mechanism 6 maintains flexible adaptive contact with the direction perpendicular to the indexing line of the rack 1, achieving efficient cleaning of oil stains on the rack 1 without damaging the tooth surface. The oil scraping stroke adaptation mechanism 5 can be used to adjust the lifting of the oil scraping mechanism 6, thereby ensuring that the oil scraping mechanism 6 is always in close contact with the outer wall of the rack 1 during the oil scraping process, ensuring the reliability of oil scraping. In addition, after the oil scraping is completed, the oil scraping mechanism 6 needs to be lifted to facilitate the lifting operation of the entire mechanism. Therefore, the oil scraping stroke adaptation mechanism 5 can simultaneously detach the oil scraping mechanism 6 from the outer surface of the rack 1. When lifting and adjusting are required, the worm gear lift 501 is driven by motor 502, which in turn drives the worm support plate 505, which in turn drives the lower support plate 507, which in turn drives the corresponding side slide plate 508 to lift and slide, ultimately driving the entire oil scraping mechanism 6 to lift and slide along the tooth surface direction, and ensuring that the oil scraping mechanism 6 is always in close contact with the outer wall of the rack 1.

[0047] Furthermore, the double-screw 601 on the oil scraping mechanism 6 is mounted on the side slide plate 508. The threads at the left and right ends of the double-screw 601 rotate in opposite directions. A synchronous pulley 604 is mounted on one end of the double-screw 601, and the other synchronous pulley is mounted on the side slide plate 508. The two synchronous pulleys 604 are driven by a synchronous belt. The motor 611 drives the synchronous pulleys 604 to rotate the double-screw 601. Scraper supports 602 are respectively mounted on the two ends of the threads of the double-screw 601. The scraper supports 602 are guided by two sets of guide rods 603. Below the scraper supports 602 is a scraper adjusting seat 607. The back of the joint seat 607 is assembled with the scraper support 602 via the guide rail slider assembly 612. A scraper blade 606 is mounted on the scraper adjusting seat 607. The mounting surface of the scraper adjusting seat 607 is wedge-shaped, allowing the scraper blade 606 to form a certain angle with the tooth surface of the rack 1 after installation, reducing the movement resistance of the scraper blade 606 during oil cleaning. Two sets of spring guide rods 610 are respectively mounted at both ends of the scraper adjusting seat 607. A spring 609 is mounted on each spring guide rod 610. The other end of the spring guide rod 610 is mounted on a limiting plate 608, which is mounted on the scraper support 602. Through the aforementioned scraping mechanism 6, oil scraping operations on the tooth surface can be achieved. During operation, the motor 611 drives the synchronous pulley 604, which in turn drives the double-screw 601 via the synchronous pulley 604 and the synchronous belt 605. The double-screw 601 then drives the scraper support 602, which in turn drives the corresponding oil scraping adjustment seat 607. The oil scraping adjustment seat 607 drives the oil scraper 606, which moves along the rack 1 to scrape away the oil stains on the outer surface of the rack 1.

[0048] Furthermore, the oil scraping mechanism 6 is raised and lowered via the lifting mechanism 7. When the oil scraping mechanism 6 is in working condition, its oil scraper 606 can be finely adjusted via the guide rail slider assembly 612 and the spring 609 to ensure that the oil scraper 606 can adapt to the displacement deviation in the direction of the rack 1's indexing line when the oil scraping mechanism 6 is in working condition. This ensures that the oil scraper 606 is always in contact with the rack tooth surface, and that the oil scraper 606 maintains a certain pressure with the rack tooth surface during the oil scraping process. Through the above-mentioned pressing method, oil can be effectively scraped off from the outer surface of the rack.

[0049] Furthermore, the scraper blade 606 is made of carbon fiber to ensure that the tooth surface is not damaged; the surface of the scraper blade 606 is coated with an oleophobic coating, and the two scraper blades 606 are arranged with a larger top and a smaller bottom in a funnel shape to ensure that the oil accumulated on the scraper blade 606 during the oil cleaning process slides down to the oil collection tray at the bottom by its own weight.

[0050] Furthermore, the scraper blade 606 and the scraper adjustment seat 607 are quickly detachable, facilitating the rapid replacement of the scraper blade 606; the bottom of the scraper blade 606 has the same shape as the tooth profile of the rack 1, ensuring that the scraper blade can simultaneously contact multiple tooth surfaces, thereby improving the efficiency of oil stain cleaning.

[0051] Example 2: The method of using the large-module long-stroke drive rack oil sludge cleaning device for the vertical ship lift includes the following steps: Step 1: The rack oil stain cleaning device is initially located at the top of the rack, which does not affect the normal operation of the ship lift. When rack oil stain cleaning is required, the ship lift moves to the lowest elevation, the lifting mechanism 7 is activated, and the frame 3, guide mechanism 4, oil scraping stroke adaptation mechanism 5 and oil scraping mechanism 6 are lowered as a whole to a position 0.2~0.5m directly above the construction platform 2, ensuring that the bottom contour of the oil scraper 606 coincides with the rack tooth profile as much as possible. Step 2: By controlling motor 502, the oil scraper 606 on the oil scraper mechanism 6 is slowly brought into contact with the tooth surface of rack 1 until the spring 506 is compressed to 1 / 3 of its natural length and then the machine is stopped. This ensures that the oil scraper 606 enters the predetermined working state. During the process of the oil scraper 606 slowly contacting the tooth surface of rack 1, the scraper adjustment seat 607 slides relative to the scraper support 602, so that the oil scraper 606 adapts to the displacement deviation in the direction of the rack 1's index line, ensuring that the oil scraper 606 simultaneously and accurately contacts multiple tooth surfaces. Step 3: Start motor 2 611 and move the scraper 606 to both ends of the rack 1 until it is completely separated from the rack. Stop the machine to scrape the oil on the tooth surface and tooth root to both ends of the rack 1. The oil will fall into the oil collection grooves on both sides under the action of gravity. Adjust the length of the scraper 606 according to the situation to ensure that the oil on 6 to 8 tooth surfaces can be cleaned at the same time to improve cleaning efficiency. Step 4: When the scraper blade 606 has completely disengaged from the tooth surface of the rack 1, control motor 1 502 to raise the scraper blade 606 back to the upper limit position, operate the lifting mechanism 7 to raise the entire device by one working stroke, and then operate motor 2 611 to return the scraper blade 606 to the initial scraping position. Step 5: Repeat steps 2 to 4 until the oil stains on the entire tooth surface of rack 1 are cleaned.

8. The method of using the large-module long-stroke drive rack oil stain cleaning device for vertical ship lifts according to any one of claims 5-7, characterized in that, It includes the following steps: Step 1: The rack oil cleaning device is initially located at the top of the rack, which does not affect the normal operation of the ship lift. When the rack oil cleaning operation is required, the ship lift runs to the lowest elevation, the lifting mechanism (7) is activated, and the frame (3), guide mechanism (4), oil scraping stroke adaptation mechanism (5) and oil scraping mechanism (6) are lowered as a whole to a position 0.2~0.5m directly above the construction platform (2), ensuring that the bottom contour of the oil scraper (606) coincides with the rack tooth profile; Step 2: By controlling motor 1 (502), the oil scraper (606) on the oil scraper mechanism (6) is slowly brought into contact with the tooth surface of the rack (1) until the compression of spring 1 (506) is 1 / 3 of its natural length. This ensures that the oil scraper (606) enters the predetermined working state. During the process of the oil scraper (606) slowly coming into contact with the tooth surface of the rack (1), the scraper adjustment seat (607) slides relative to the scraper support (602) so that the oil scraper (606) adapts to the displacement deviation in the direction of the indexing line of the rack (1) and ensures that the oil scraper (606) is precisely in contact with multiple tooth surfaces at the same time. Step 3: Start motor 2 (611) and make the scraper (606) move towards both ends of the rack (1) until it is completely separated from the rack and then stop the machine. Scrape the oil stains on the tooth surface and tooth root to both ends of the rack (1) and let the oil stains fall into the oil collection grooves on both sides under the action of gravity. Adjust the length of the scraper (606) according to the situation to ensure that the oil stains on 6 to 8 tooth surfaces can be cleaned at the same time. Step 4: When the scraper blade (606) runs until it is completely disengaged from the tooth surface of the rack (1), control motor one (502) to raise the scraper blade (606) back to the upper limit position, operate the lifting mechanism (7) to raise the entire device by one working stroke, and then operate motor two (611) to return the scraper blade (606) to the initial scraping position. Step 5: Repeat steps 2 to 4 until the oil stains on the entire tooth surface of the rack (1) are cleaned.
