[0024] The lifting mechanism 2 comprises a driving lifting device (the angle is not shown in the figure, which can be arranged below the conveying roller bed or at other positions), a supporting assembly 20 and a suction assembly, the driving lifting device drives the supporting assembly 20 to jack up the workpiece, the suction assembly 21 is in contact with and sucks the workpiece, and then the workpiece is jacked away from the conveying roller bed.

[0025] When the lifting mechanism moves up and down, no position interference is generated between the lifting mechanism and the conveying roller bed.

[0026] Specifically, in the example, the supporting assembly 20 comprises a long supporting plate and a short supporting plate (as shown in Figure 1 , which are arranged on the mounting base), the long supporting plate and the short supporting plate are arranged in line along the conveying direction of the conveying roller bed, and the long supporting plate and the short supporting plate are respectively arranged in extension along the direction perpendicular to the conveying direction of the conveying roller bed.

[0027] As Figure 1 shown, in order to adapt to the shape features of various types of large steel pieces, in the example, the long supporting plate comprises at least one, the short supporting plate comprises at least one, the long supporting plate is arranged in the middle of the arrangement area, the short supporting plate is arranged in line on one side of the long supporting plate, and the remaining short supporting plates are arranged in line on the opposite side of the long supporting plate.

[0028] Further, in order to realize further fixation of the initially positioned workpiece, facilitate subsequent operations, such as polishing process, etc., in the embodiment, the mounting base between every two adjacent support plates of the long support plates and the short support plates arranged in one row is respectively provided with a suction assembly 21.

[0029] Specifically, the suction assembly 21 is arranged close to the side surface of the corresponding support plate. The support plate at this position can be the corresponding long support plate or short support plate, and the long and short support plates are determined according to the actual arrangement position.

[0030] Preferably, the suction assembly is an electromagnet.
