In the specific cleaning process, the lifting mechanism 7 drives the entire frame 3 to rise and fall along the rack 1 under the guidance of the guide mechanism 4. Whenever it moves to a certain height, the scraping mechanism 6 is appropriately pressed against the outer surface of the rack 1 through the scraping stroke adaptation mechanism 5, and then the scraping mechanism 6 is synchronously started, and the oil stains on the outer surface of the rack 1 are scraped and cleaned through the scraping mechanism 6. Moreover, through three sets of guide mechanisms, the device can crawl accurately along the rack, and can scrape off the oil stains on 6 to 8 tooth surfaces at the same time, and the oil stain cleaning operation is efficient.

[0043] Furthermore, the frame 3 is assembled from a top frame 301, a side frame 302 and a wire rope connector 303. The two sets of side frames 302 are mounted on the lower end surface of the top frame 301, and the wire rope connector 303 is mounted on the upper end surface of the top frame 301.

[0045] Furthermore, the forward wheel group 401 and the lateral wheel group 403 each include a guide wheel 4011, the guide wheel 4011 is mounted on a guide wheel shaft 4013 via a bearing 4019, the bearing 4019 is positioned via a transparent 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 group 4016 is mounted on the disc spring shaft 4018, the disc spring sleeve 4017 is welded to both sides of the guide frame 4014, and the disc spring sleeve 4018 is welded to both sides of the guide frame 4014. 017 is in sliding contact with the sliding plate 4020, ensuring that the guide frame 4014 and the guide wheel 4011 move axially along the disc spring shaft 4018 as a whole. The sliding plate 4020 is installed on the fixed bracket 4021 by bolts, 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 the adjusting nut 4015. The adjusting nut 4015 can adjust the compression of the disc spring to adjust the gap and contact force between the guide wheel 4011 and the rack 1 guide rail. The above-mentioned positive wheel group 401 and lateral wheel group 403 can ensure that a certain clamping force is always maintained between the rack 1 during the guiding process, thereby ensuring the smoothness of the lifting process.

[0046] Furthermore, the scraping stroke adaptation mechanism 5 includes a worm gear lift 501, the worm gear lift 501 is driven by a motor 502, the worm gear lift 501 and the motor 502 are both 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 through two sets of guide rail slider assemblies 509, the side slide plates 508 are fixed to the lower support plate 507, the spring guide rod 510 is mounted with a spring 506, the four The lower end of the spring guide rod 1 510 is fixed to the lower support plate 507, the mounting hole of the worm support plate 505 passes through the spring guide rod 1 510, and a limit nut is installed on the upper end of the spring guide rod 1 510.

Therefore, the scraping stroke adaptation mechanism 5 can synchronously separate the scraping mechanism 6 from the outer surface of the rack 1. When lifting and lowering adjustment is required, the worm gear lift 501 is driven by the motor 502, and the worm gear lift 501 drives the worm support plate 505, and the worm support plate 505 drives the lower support plate 507, and then the lower support plate 507 drives the corresponding side slide plate 508 to lift and slide, and finally drives the entire oil scraper mechanism 6 to lift and lower along the tooth surface direction, so that the oil scraper mechanism 6 is always close to the outer wall of the rack 1.

The mounting surface of the scraper adjustment seat 607 is wedge-shaped, so that the oil scraper 606 can be at a certain angle with the tooth surface of the rack 1 after installation, reducing the movement resistance of the oil scraper 606 during the oil cleaning process. Two sets of spring guide rods 610 are respectively installed at both ends of the scraper adjustment seat 607. The spring guide rods 610 are equipped with springs 609. The other end of the spring guide rods 610 is installed on the limit plate 608, and the limit plate 608 is installed on the scraper support 602. The oil scraping operation on the tooth surface can be achieved through the above-mentioned scraper mechanism 6. During the working process, the synchronous wheel 604 is driven by the motor 2 611, and the double-rotation screw 601 is driven by the synchronous wheel 604 and the synchronous belt 605.

Through the above-mentioned pressing method, the oil can be effectively scraped off the outer surface of the rack.

[0049] Furthermore, the scraper plate 606 is a carbon plate to ensure that the tooth surface is not damaged; the surface of the scraper plate 606 is sprayed with an oleophobic coating, and the two scraper plates 606 are arranged in a trumpet-shaped manner with a larger top and a smaller bottom, to ensure that the oil accumulated on the scraper plate 606 during the oil cleaning process slides down to the oil receiving pan at the bottom by its own weight.

[0050] Furthermore, the scraper plate 606 and the scraper plate adjustment seat 607 are quickly detachably connected to facilitate the rapid replacement of the scraper plate 606; the bottom of the scraper plate 606 is the same shape as the tooth profile of the rack 1, ensuring that the scraper plate fits multiple tooth surfaces at the same time, thereby improving the efficiency of oil cleaning.

When the oil scraper plate 606 slowly contacts the tooth surface of the rack 1, the scraper plate adjustment seat 607 slides relative to the scraper plate support 602, so that the oil scraper plate 606 adapts to the displacement deviation in the direction of the index line of the rack 1, so as to ensure that the oil scraper plate 606 accurately fits multiple tooth surfaces at the same time; Step 3: Start the second motor 611, and make the scraper plate 606 run toward the two end surfaces of the rack 1 until it is completely separated from the rack and then stops, scraping the oil stains on the tooth surface and tooth root to the two end surfaces of the rack 1, so that the oil stains fall into the oil receiving grooves on both sides under the action of gravity.
