[0028] Refer to Figure 1-2 and Figure 4, an embodiment provided by the present utility model: an adjustable maintenance platform, including a base 1 and a maintenance table 5. At the center of the upper end face of the base 1, a first support column 2 is fixedly arranged.

On the upper end face of the cleaning box 8, a sealing cover 10 is fixedly arranged. At the center of the upper end face of the sealing cover 10, a sealing handle 11 is fixedly arranged. At the center of the front end face of the cleaning box 8, an operation box 13 is fixedly arranged. On the front end face of the operation box 13, a connecting rod 14 is fixedly arranged. At the center of the front end face of the maintenance table 5, a first moving groove 15 is formed. At the centers of both sides of the inner wall of the first moving groove 15, a fixed rod 17 is fixedly arranged. On one side of the outer wall of the fixed rod 17, a second moving block 16 is slidably sleeved.

[0030] Specifically, the maintenance platform is supported by the first support column 2. Then, with the cooperation of the lifting mechanism 4, the overall use height of the maintenance platform can be flexibly adjusted, facilitating the operator to work in a comfortable posture. Then, rotate the rotating handle 19, so that the rotating rod 18 applies a horizontal squeezing force and a vertical rotating force to the cleaning box 8 fixedly connected to the first moving block 12. Then, under the action of the fixed rod 17, the rotating force of the rotating rod 18 is offset, so that the cleaning box 8 moves horizontally along the fixed rod 17 and the rotating rod 18 under the action of the horizontal squeezing force. While rotating the rotating handle 19, start the servo motor 20.

When the cleaning box 8 moves above the dust collection assembly 7, at this time, the electromagnet 901 is powered off. Since the magnetic field of the electromagnet 901 disappears after power-off, the metal chips and debris fall into the dust collection box 702, thus realizing the purpose of cleaning and collection and facilitating the improvement of the cleanliness of the working environment.

[0031] Refer to Figure 4, the lifting mechanism 4 includes a sleeve 401, a first-stage gear 402, a second-stage gear 404, and a second support column 407. The sleeve 401 is rotatably arranged at the center of the lower end face of the inner wall of the base 1. The first-stage gear 402 is fixedly arranged at the lower position of the outer wall of the sleeve 401. The output end of the first motor 3 is fixedly provided with a first rotating shaft 403. The second-stage gear 404 is fixedly sleeved on the outer wall of the first rotating shaft 403 at the front position of the first-stage gear 402. The first-stage gear 402 and the second-stage gear 404 are meshed with each other. There is a thread at the center of the lower position of the outer wall of the second support column 407. The lower part of the outer wall of the second support column 407 is threadedly connected to the sleeve 401. On both sides of the upper position of the outer wall of the second support column 407, a first slider 405 is fixedly arranged. On both sides of the upper position of the center of the inner wall of the first support column 2, a chute 406 is provided. Both of the two first sliders 405 are slidably clamped in the two chutes 406. The upper end face of the second support column 407 is fixedly connected to the lower end face of the inspection table 5 at the opposite side position.

[0032] Specifically, by starting the first motor 3 to drive the rotation of the first rotating shaft 403, the rotation of the second-stage gear 404 is driven under the rotation of the first rotating shaft 403. Then, under the meshing action of the first-stage gear 402 and the second-stage gear 404, the rotation of the first-stage gear 402 is driven. Then, under the rotation of the first-stage gear 402, the rotation of the sleeve 401 is driven. Then, under the threaded connection between the sleeve 401 and the second support column 407, the second support column 407 can be lifted and lowered in the vertical direction under the rotation action of the sleeve 401. And with the sliding clamping cooperation of the two first sliders 405 and the two chutes 406, it can effectively prevent the second support column 407 from swaying left and right or tilting during the lifting process, improving the overall stability of the inspection platform. At the same time, it is convenient for the operator to flexibly adjust the use height according to their height, enabling the operator to work in the most comfortable posture.

[0033] Refer to Figure 1 , Figure 4 , the dust collection assembly 7 includes two slide rails 701 and a dust collection box 702. The two slide rails 701 are respectively fixedly arranged at the positions of the front and rear ends of one side of the lower end face of the inspection table 5. At the centers of the front and rear end faces of the dust collection box 702, a second slider 703 is fixedly arranged. Both of the two second sliders 703 are slidably clamped in the two slide rails 701. At the center of one side of the dust collection box 702, a dust collection handle 704 is fixedly arranged.

[0034] Specifically, by pulling the dust collection handle 704, with the sliding clamping cooperation of the two second sliders 703 and the slide rails 701, the stability of the dust collection box 702 when sliding in the slide rails 701 can be improved, thereby realizing the extraction of the dust collection box 702, facilitating the centralized collection of metal chips and residues on the surface of the inspection platform, and being convenient for later cleaning and maintenance.

[0035] Refer toFigure 2-5 , the cleaning mechanism 9 includes an electromagnet 901, a second rotating shaft 902 and a second mounting plate 907. The second rotating shaft 902 is fixedly arranged at the output end of the servo motor 20. A first mounting plate 903 is fixedly arranged on the rear end face of the second rotating shaft 902. A connecting shaft 905 is fixedly arranged at the center of the rear end face of the second mounting plate 907, and one end of the connecting shaft 905 is rotatably connected to a position on the opposite side of the rear end face of the inner wall of the cleaning box 8. Mounting frames 909 are fixedly arranged on both sides of the opposite sides of the first mounting plate 903 and the second mounting plate 907. Grooves are opened at the centers of the opposite sides of the first mounting plate 903 and the second mounting plate 907. A sliding rod 904 is fixedly arranged at the center positions of the upper and lower end faces of the inner wall of one of the two grooves located at the center of the rear end face of the second mounting plate 907. A threaded rod 908 is rotatably arranged at the center positions of the upper and lower end faces of the inner wall of one of the two grooves located at the center of the front end face of the first mounting plate 903. A round shaft 23 is slidably sleeved on the outer wall of the sliding rod 904, and the other end of the round shaft 23 is threadedly connected to a position on one side of the outer wall of the threaded rod 908. The electromagnet 901 is fixedly sleeved on the center of the outer wall of the round shaft 23, and a housing 906 is fixedly sleeved on the outer wall of the electromagnet 901.

[0036] Specifically, when an operator cleans the metal chips or residues on the surface of the maintenance platform, first rotate the threaded rod 908, so that the threaded rod 908 exerts a horizontal rotational force and a vertical extrusion force on one end of the round shaft 23. Then, under the action of the sliding rod 904, the rotational force of the threaded rod 908 is offset, so that the round shaft 23 moves vertically along the threaded rod 908 and the sliding rod 904 under the action of the vertical extrusion force, thereby realizing the adjustment of the cleaning distance between the electromagnet 901 and the maintenance platform, and can be flexibly adjusted according to the distribution and quantity of the metal chips or residues on the surface of the maintenance platform, which is convenient for improving the adsorption efficiency of the metal chips or residues;

[0037] When the cleaning height reaches the required value, start the servo motor 20 at this time to drive the second rotating shaft 902 to rotate 180 degrees on both sides. Under the rotation of the second rotating shaft 902, the two sides of the first mounting plate 903 are driven to rotate 180 degrees. Since the first mounting plate 903 and the second mounting plate 907 are fixedly connected through the mounting frame 909, the second mounting plate 907 and the connecting shaft 905 are driven to rotate 180 degrees on both sides. Then, the electromagnet 901 is driven to rotate 180 degrees on both sides under the rotation of the first mounting plate 903 and the second mounting plate 907. Since the servo motor 20 rotates the second rotating shaft 902 180 degrees on both sides, the problem of cable winding of the electromagnet 901 can be effectively avoided. At the same time, the metal chips on the surface and around the maintenance platform can be effectively adsorbed under the rotation of the electromagnet 901, further improving the cleaning efficiency.

[0038] Working principle: When in use, the operator first starts the first motor 3 through the control panel, and drives the second support column 407 to move up and down in cooperation with the lifting mechanism 4, so that the operator can operate in a comfortable position. Then, the sealing cover 10 is opened, and the threaded rod 908 is rotated to drive the round shaft 23 to move vertically. Furthermore, according to the distribution and quantity of metal chips or residues on the surface of the maintenance platform, the cleaning distance between the electromagnet 901 and the maintenance platform can be flexibly adjusted. Then, by rotating the rotating handle 19 to drive the rotation of the rotating rod 18, the rotational force of the rotating rod 18 is offset under the action of the fixed rod 17. Thus, the cleaning box 8 moves horizontally along the fixed rod 17 and the rotating rod 18 under the action of the horizontal extrusion force;

[0039] Secondly, while rotating the rotating handle 19, the servo motor 20 is started. With the cooperation of the cleaning mechanism 9, the electromagnet 901 effectively cleans the metal chips and residues on the surface of the maintenance platform. When the cleaning box 8 moves above the dust collection assembly 7, the electromagnet 901 is powered off at this time. Since the magnetic field of the electromagnet 901 disappears after being powered off, the metal chips and debris fall into the dust collection box 702, thus achieving the purpose of cleaning and collection, which is convenient for improving the cleanliness of the working environment.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
