[0124] Working principle: When the staff uses this device, the staff inserts the square steel into a protrusion 8, and then the staff starts the two first cylinders 6 through the control panel 33. The telescopic ends of the two first cylinders 6 drive the two splints 7 to move toward each other, and the two splints 7 drive the two protrusions 8 to move toward each other. The two splints 7 cooperate with the two protrusions 8 to tightly fix the steel structure, and then the staff closes the first cylinders 6 through the control panel 33.

[0125] Before performing the grinding work, initial preparations should be made so that the grinding disc 15, the laser transmitter 19, the receiver 20 and the plurality of bristles 32 are all located at the far left.

[0127] When the horizontal plate 17 drives the two mounting blocks 18 to move leftward, the two mounting blocks 18 drive the laser transmitter 19 and the receiver 20 to move leftward, so that the laser transmitter and the receiver are located at the leftmost side.

[0128] When the transverse plate 17 drives the plurality of bristles 32 to move leftward, the plurality of bristles are also located at the far left, thus completing the initial preparation work.

[0129] When the steel structure needs to be polished, the staff starts the grinder 14 and the second cylinder 12 through the control panel 33, the grinder 14 works, the rotating shaft of the grinder 14 drives the polishing disc 15 to rotate, the second cylinder 12 works, the telescopic end of the second cylinder 12 drives the installation box 13 to move downward, the installation box 13 drives the connecting rod 21 to move downward, drives the grinder 14 to move downward, the grinder 14 drives the polishing disc 15 to move downward, when the polishing disc 15 contacts the upper surface of the steel structure, the staff turns off the second cylinder 12 through the control panel 33, and then the steel structure can be polished.

[0130] When the installation box 13 drives the connecting rod 21 to move downward, the connecting rod 21 compresses the telescopic rod 22 and the spring 23 , so that the vibration generated by the grinding disc 15 when grinding the steel structure can be buffered by the telescopic rod 22 and the spring 23 .

[0131] When it is necessary to comprehensively grind the upper surface of the steel structure, the staff controls the rotating shaft of the first motor 9 to rotate forward through the control panel 33, the rotating shaft of the first motor 9 drives the first threaded rod 10 to rotate forward, the first threaded rod 10 drives the slider 11 to move right, the slider 11 drives the second cylinder 12 to move right, the telescopic end of the second cylinder 12 drives the installation box 13 to move right, the installation box 13 drives the connecting rod 21 to move right, drives the grinder 14 to move right, the grinder 14 drives the grinding disc 15 to move right, and the grinding disc 15 can comprehensively grind the upper surface of the steel structure.

[0132] When the installation box 13 drives the connecting rod 21 to move right, the connecting rod 21 drives the telescopic rod 22 and the spring 23 to move right, the telescopic rod 22 and the spring 23 drive the cross plate 17 to move right, the cross plate 17 drives a number of bristles 32 to move right, drives the two installation blocks 18 to move right, drives the plug rod 26 to move right, the plug rod 26 drives the piston 25 to move right, the piston 25 pushes the cold air in the cylinder 24 to blow toward the surface of the steel structure through the one-way valve 31, the exhaust hose 29, and the blowing head 30 in sequence, the blown cold air reduces the temperature of the upper surface of the steel structure and the grinding disc, and blows away the debris generated by grinding.

[0133] When the horizontal plate 17 drives the two mounting blocks 18 to move right, the two mounting blocks 18 drive the laser transmitter 19 and the receiver 20 to move right. The staff starts the laser transmitter 19 through the control panel 33. The laser transmitter 19 emits laser to irradiate the upper surface of the steel structure. The upper surface of the steel structure refracts the laser. After refraction, the laser is received by the receiver 20. The receiver 20 transmits the laser signal to the control panel 33. The staff can measure and analyze the characteristics of the reflected light through the control panel 33, and then detect the polishing effect of the upper surface of the steel structure.

[0134] When the horizontal plate 17 drives the plurality of bristles 32 to move rightward, the plurality of bristles 32 clean the debris dropped from the upper surface of the base 2, so that the debris is gathered together, which is convenient for subsequent staff to remove the debris.
