The clamping plate 402 is in an L-shaped structure, and a plurality of anti-slip rubber strips 403 are fixedly arranged on the surface of the clamping plate 402. The clamping plate 402 contacts the surface of the coating test block 6 through the anti-slip rubber strips 403.
[0030] A bolt positioning hole is opened on the side surface of the positioning sleeve 401. A positioning bolt 404 is threadedly connected to the inner wall of the bolt positioning hole. The end of the positioning bolt 404 abuts against the side surface of the clamping plate 402.

[0031] The limiting mechanism 4 is used to limit and fix the coating test block 6. A testing mechanism 5 is arranged inside the base box 2. The testing mechanism 5 is used to polish the surface of the coating test block 6. By arranging the limiting mechanism 4 on the surface of the rotating tray 3, during use, the two clamping plates 402 of the limiting mechanism 4 can be used to clamp and fix the coating test block 6 on the surface of the rotating tray 3, and the clamping plate 402 can be adjusted up and down inside the positioning sleeve 401, so as to be applicable to coating test blocks 6 of different thicknesses.

The position of the polishing roller 505 corresponds to that of the rotating tray 3, and the polishing roller 505 is in rolling connection with the surface of the coating test block 6 through the polishing sleeve 506.
[0034] It should be noted that by arranging the counterweight box 509 on the surface of the movable mounting seat 502, the counterweight weights 509 can be put into the counterweight box 507 during the test to increase the load of the polishing roller 505, thereby facilitating the adjustment of the friction force of the polishing roller 505. And the weight limiting rod can limit the counterweight weights 509, improving the stability of the weights during the rolling polishing process.
[0035] When conducting wear resistance testing on the coating test block 6, the driving motor 7 can be used to drive the rotation of the rotating support column 8, thereby driving the rotation of the coating test block 6 on the surface of the rotating tray 3. Then, the grinding roller 505 on the surface of the movable mounting seat 502 is placed on the surface of the coating test block 6, and the surface of the coating test block 6 is ground by the grinding roller 505 to achieve the grinding effect on the coating. Moreover, during the grinding process, the position of the grinding roller 505 can be adjusted by the electric telescopic rod 503 to increase the grinding range, so as to facilitate the staff to observe and detect the wear resistance of the thermal insulation coating on the coating surface.
[0036] A limit box 9 is fixedly connected to the inner wall of the equipment box 1. A limit support block 10 is slidably arranged on the inner wall of the limit box 9.
