[0078] The operation process of the automatic grinding device for the bridge deck unit in this embodiment is as follows:

[0079] First, the position of the grinding mechanism 300 is adjusted along the first direction by the walking mechanism 100, so that the grinding mechanism 300 that needs to perform grinding operation moves to the starting grinding operation position. Specifically, the workpiece 500 to be ground is placed on the working platform 600, and the electric control cabinet 140 controls the driving trolley 120 to move forward or backward along the fixed track 130 in the first direction, so that the beam 110 and the multiple position adjustment mechanisms 200 and the multiple grinding mechanisms 300 on the beam 110 are moved as a whole to the starting grinding operation position in the length direction of the workpiece 500, and the electric control cabinet 140 controls the driving trolley 120 to cut off the power and lock the brake; wherein, the length direction of the workpiece 500 is parallel to the first direction;

[0080] The position of the grinding mechanism 300 is adjusted along the second direction by the transverse movement assembly 210 of the position adjustment mechanism 200 to adapt to the grinding parameters of the workpiece 500. Specifically, the second motor 2131 drives the gear 214 to rotate, and the gear 214 is meshed with the rack 111 to achieve the distance between two adjacent position adjustment mechanisms 200 along the second direction, so that the center distance between the adjacent grinding mechanisms 300 in the second direction is equal to the grinding center distance L2 of the workpiece 500 to be ground; the adjustment of the mechanism 300 to be ground in the second direction causes the second motor 2131 to be powered off and locked, so that the position adjustment mechanism 200 cannot move laterally.

[0081] The grinding operation is performed on the workpiece 500 by cooperating with the grinding mechanism 300 and the lifting assembly 220. Specifically, the first motor 321 of the grinding mechanism 300 drives the output shaft 3221 of the first reducer 322 to rotate, thereby driving the grinding piece 330 installed on the output shaft 3221 of the first reducer 322 to rotate; the dust removal mechanism 400 is started to perform dust removal; the driving member of the lifting assembly 220 controls the telescopic rod 222 to be retracted, so that the grinding mechanism 300 as a whole is lowered to the working position along the third direction, and when the grinding piece 330 contacts the workpiece 500 for grinding, the driving member of the lifting assembly 220 continues to control the telescopic rod 222, so that the position of the telescopic rod 222 is adapted to the grinding piece 330 to grind the workpiece 500.

[0082] During the process of the grinding member 330 of the grinding mechanism 300 grinding the workpiece 500, the electric control cabinet 140 is also required to control the driving trolley 120 to move along the track 130 in the first direction, so as to grind along the length direction of the workpiece 500. After the grinding along the length direction of the workpiece 500 is completed, the electric control cabinet 140 controls the driving trolley 120 to move, and after the driving trolley 120 drives the crossbeam 110 to move to the safe area, the electric control cabinet 140 controls the driving trolley 120 to cut off the power and lock the brake; the first motor 321 of the grinding mechanism 300 is powered off, and the driving member of the lifting assembly 220 controls the telescopic rod 222 to extend, so that the grinding mechanism 300 as a whole rises along the third direction to the waiting position for operation, waiting for the next workpiece 500 to be in place, so as to grind the next workpiece 500.

[0083] It should be noted that, in the second direction, the middle position between two grinding positions P1 corresponding to each group of welds on the workpiece 500 is regarded as the center line; the distance between two adjacent center lines in the second direction is the grinding center distance L2.

[0084] It should also be noted that, in this embodiment, the position adjustment mechanism 200 and the grinding mechanism 300 can be increased or decreased as a whole according to the actual amount of grinding on the workpiece 500, or the transverse movement component 210 of the position adjustment mechanism 200 can be moved as a whole along the second guide rail 112 to a non-working area for avoidance.

[0085] It should also be noted that the electric control cabinet 140 synchronously controls the two driving trolleys 120 on both sides of the beam 110. The second driving assembly 213 of each transverse movement assembly 210 can independently control a corresponding position adjustment mechanism 200 to move along the second direction. The first driving assembly 320 of each grinding mechanism 300 can independently control a corresponding grinding mechanism 300 to perform a grinding operation. The driving member of each lifting assembly 220 can independently control a corresponding telescopic rod 222 to retract or extend. The above arrangement effectively solves the technical problem in the prior art that the grinding flap wheel has been worn for a long time, resulting in different heights during operation and the need for adaptive height adjustment.

[0086] The automated grinding device for the bridge deck unit in this embodiment is suitable for automated grinding of weld positions before assembly and welding of the bridge deck unit. It not only has high grinding efficiency and saves labor, but also can reduce pollution to the environment, keep the bridge deck unit clean, and is also conducive to improving grinding quality.
