[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0026] Example

[0027] like Figure 1-6 As shown;

[0028] The safety door structure of the loading platform of the grinding device includes: a safety door 1, an observation window 11 is symmetrically arranged on the safety door 1, the safety door 1 is clamped on the inner side of the frame 8, and corresponds to the loading port 81 on the frame 8, a lifting ear 13 is arranged on the top of the safety door 1, a lifting rope 21 is tied to the lifting ear 13, and the other end of the lifting rope 21 is wound on the winding roller at the output end of the driving member 2, the driving member 2 can be a motor, and the driving member 2 is installed on the inner side of the frame 8, and guide wheels 12 are symmetrically and evenly arranged on both sides of the safety door 1, and the guide wheels 12 are in contact with the inner wall of the frame 8, and the driving member 2 is driven to make the winding roller The roller is wound up or loosened, so that the safety door 1 is raised or moved down through the lifting rope 21; a J-shaped groove 4 is fixed on the inner side of the frame 8, and a scraper 5 is rotatably installed on one side of the J-shaped groove 4. The scraper 5 matches the observation window 11, and a torsion spring is provided on the rotating part of the scraper 5, so that the scraper 5 always has a tendency to expand outward, so as to facilitate contact with the observation window 11. When the safety door 1 moves down, it will contact with the scraper 5, so that the dust attached to the surface of the observation window 11 is scraped off by the scraper 5, so as to maintain the clarity of the observation window, so that the staff can observe the grinding situation of the grinding robot through the observation window 11;

[0029] Furthermore, a wiping plate 6 is rotatably mounted on the corresponding J-shaped groove 4 below the scraper 5, and a torsion spring is provided on the rotating part of the wiping plate 6, so that the wiping plate 6 always has a tendency to expand outward, so as to facilitate contact with the observation window 11; in addition, a wiping cloth is provided at the movable end of the wiping plate 6, so as to facilitate wiping the surface of the observation window 11 and improve the clarity of the observation window 11;
