[0029] The coating agent assembly 4 comprises a storage tank 40 arranged on the top plate 26 for storing the coupling agent. A pump body 41 is arranged on the side of the storage tank 40. The input end of the pump body 41 is connected with the storage tank 40 so as to draw out the coupling agent in the storage tank 40. The output end of the pump body 41 is connected with a delivery pipe 42. The other end of the delivery pipe 42 is connected with a distribution channel 43.

The cooperation between the moving wheels 27 and the moving grooves 12 further ensures the stability and accuracy of the top plate 26 during movement, so as to avoid deviation or shaking.

[0031] In actual operation, the use process of the device is as follows:

[0032] Device positioning: The device is stably placed above the sliding bed plate to ensure that the position of the device and the sliding bed plate is relatively accurate, so as to ensure the effectiveness of subsequent operations. Then, the plurality of lifting legs 10 are controlled to be lowered synchronously until the dust removal assembly 3, the coating agent assembly 4 and the probe 50 are in contact with the surface of the sliding bed plate. During this process, the contact state of each component needs to be closely observed to ensure that it is fully attached to the sliding bed plate, laying a foundation for subsequent cleaning, coating and detection work;

[0033] Device start and cleaning operation: after each component is in place, the motor 22, air pump 30 and ultrasonic flaw detector 5 are started at the same time. When the motor 22 is started, the driving structure inside the motor drives the lead screw 20 to rotate. Under the action of the precise cooperation between the lead screw 20 and the lead screw nut 25, the top plate 26 moves stably along the predetermined track. At the same time, the air pump 30 is started, and the external air gas is quickly introduced into the air guide pipe 31. These gases gather and pressurize in the air guide pipe 31, and finally are sprayed out in the form of high-speed gas flow from several air nozzles 32. The strong gas flow acts on the surface of the sliding bed plate, and can quickly blow away the dust particles attached to the surface, realizing preliminary cleaning. In the process of moving the device forward, the shovel 34 installed at a specific position works synchronously, and the sharp edge thereof is in close contact with the surface of the sliding bed plate, which can effectively scrape off the foreign matters such as stubborn stains and clumped dust adhered to the surface, further improving the cleaning effect.

[0034] Coating operation: while the cleaning operation is being performed, the pump body 41 is started to perform the coating task. The suction force generated by the pump body 41 draws the coupling agent in the agent storage barrel 40 out, and the coupling agent is transported to the shunt row 43 through the conveying pipe 42. The special design of the shunt row 43 can ensure uniform distribution of the coupling agent, and the coupling agent is finally uniformly dropped on the coating roller 44. The coating roller 44 rolls on the surface of the sliding bed plate along with the movement of the device, and the coupling agent on the surface of the coating roller 44 is uniformly coated on the cleaned surface of the sliding bed plate during the rolling process, providing good coupling conditions for subsequent flaw detection monitoring.

[0035] Flaw detection monitoring: when the surface of the sliding bed plate is completed with the coating of the coupling agent, the probe 50 passes through the position coated with the coupling agent. The ultrasonic wave signal emitted by the ultrasonic flaw detector 5 is transmitted into the sliding bed plate through the probe 50, and the cracks and other defects in the sliding bed plate are detected and monitored by using the propagation characteristics and reflection principle of ultrasonic waves in different media. During the flaw detection process, the probe 50 transmits the received reflected signal back to the flaw detector for analysis and processing to determine whether the sliding bed plate has cracks and the position, size and other information of the cracks.
