[0028] Working principle: When in use, the pressure value for closing the electric telescopic rod 5 is set in advance through the PLC controller 8. When spraying the same batch of steel structure accessories, multiple steel structure accessories are placed at equal intervals from front to back, and their right ends are in close contact with the corresponding anti-slip rubber on the right side. After the placement is completed, the electric telescopic rod 5 is started in the positive direction, and the output shaft of the electric telescopic rod 5 drives the mounting plate 6 to move to the right through the pressure sensor 9, and the mounting plate 6 drives the four L-shaped guide rods 7 to slide to the right, and the mounting plate 6 drives the multiple splints 4 on the left side to move to the right through multiple connecting shafts and bearings, and the multiple splints 4 on the left side respectively drive the corresponding anti-slip rubber The anti-slip rubber moves to the right until it contacts the left side of the steel structure accessory. When the anti-slip rubber contacts the steel structure accessory closely, the clamping plate 4 and the mounting plate 6 are restricted from continuing to move. At this time, the pressure sensor 9 that continues to move squeezes the mounting plate 6. The pressure sensor 9 detects the squeezing force and transmits the detected pressure value to the PLC controller 8. When it is detected that the squeezing force reaches the preset value, the PLC controller 8 controls the electric telescopic rod 5 to close, thereby achieving the purpose of pressure-controlled fixation of multiple steel structure accessories. The pressure-controlled clamping and fixing method can effectively avoid the situation where the clamping force is too large or too small, thereby improving the stability of the clamping and fixing.

[0029] After fixing, the extraction pump 2 and the electric slide rail 103 are turned on. The extraction pump 2 extracts the spray liquid inside the storage box 1 through the L-shaped suction tube. The extracted spray liquid enters the mobile box 102 through the telescopic hose 3 and is sprayed out through the multiple nozzles on the mobile box 102 to spray the steel structure accessories. During the spraying process, the sliding end of the electric slide rail 103 drives the mobile box 102 to move left and right in a cycle. The mobile box 102 drives the multiple nozzles thereon to move left and right in a cycle. The mobile box 102 stretches the telescopic hose 3 while moving to the left. The mobile box 102 drives the multiple nozzles to move in a cycle for spraying, so that the tops of multiple steel structures can be sprayed synchronously and evenly.

[0030] After the top surface is sprayed, the extraction pump 2 and the electric slide rail 103 are stopped. When spraying the other side, the drive motor 18 is started in the forward direction. The output shaft of the drive motor 18 drives the screw 17 to rotate. Under the action of the threaded hole provided on the moving block 15, the screw 17 rotates and drives the moving block 15 to move forward. The moving block 15 moves forward on the two positioning rods 16. The moving block 15 drives the rack 13 to move forward through the moving plate 12. The rack 13 drives multiple gears 11 to rotate synchronously. The gear 11 drives the corresponding rotating shaft 10 to rotate. The rotating shaft 10 drives the corresponding splint 4 to rotate. The splint 4 drives the steel structure accessories to rotate through the corresponding anti-slip rubber friction. The steel structure accessories drive the left clamping plate 4 to rotate through the anti-skid rubber on the left side. When the steel structure accessories rotate to the side that needs to be sprayed facing upward, the driving motor 18 can be stopped, and the extraction pump 2 and the electric slide rail 103 can be started again to spray, thereby achieving the purpose of synchronous rotation adjustment of multiple steel structure accessories, so that multiple steel structure accessories can be sprayed at the same time, improving the spraying efficiency. After the spraying is completed, the electric telescopic rod 5 is started in the reverse direction. Similarly, the movement process of starting the electric telescopic rod 5 in the forward direction is opposite to that of the forward direction, so that the multiple clamping plates 4 on the left side are transformed into moving to the left to release the clamping and fixation of the steel structure accessories, and the sprayed steel structure accessories are taken away.
