s3: then, the electric telescopic rod (18) is started through an external power supply, so that the electric telescopic rod (18) pushes the conical rod (20) on the flat plate (19) to be inserted into the ground, and the fixing operation of the device is realized;
s4: then, a motor (12) is started through an external power supply, a second bevel gear (10) on a rotating shaft (11) is driven by the motor (12) to be meshed with a first bevel gear (9) to rotate, the first bevel gear (9) drives a first threaded rod (8) to rotate, so that the first threaded rod (8) can rotate in a third threaded hole in a triangular block (1), a fixed block (31) on an oblique block (2) moves in an oblique groove (30) in the side wall of the triangular block (1), and the relative position between the oblique block (2) and the triangular block (1) is changed;
s5: the movable block (4) can be inserted into the lower side of the bottom surface of the bridge construction concrete prefabricated part through the movement of the inclined block (2), the inclined block (2) can continuously move towards one side of the bridge construction concrete prefabricated part through the continuous rotation of the motor (12), and the bridge construction concrete prefabricated part moves into the side groove (3) on the side wall of the inclined block (2) from the side wall of the movable block (4), so that the support operation of the bridge construction concrete prefabricated part is realized;
s6: when the inclined block (2) and the movable block (4) move, the first threaded rod (8) drives the first gear (23) to rotate, the second gear (26) which is meshed with the two sides through the first gear (23) rotates, the second gear (26) drives the third threaded rod (8) to rotate in a third threaded hole in the side plate (29), so that the side plate (29) drives the concave plate (27) to move downwards, the roller (28) is continuously pushed out of the inner cavity of the groove (13), and the roller (28) is supported with the ground;
s7: after the supporting operation is finished, the inserting rod (5) is pulled out from a first threaded hole in the inclined block (2) by pulling the movable block (4), and then a second threaded rod (22) can be screwed into the first threaded holes in the inclined blocks (2) on the left side and the right side by rotating a threaded sleeve (21) on the connecting rod (15), so that the connection operation of the device on the left side and the right side is realized, and then the electric telescopic rod (18) is controlled by a power supply to be recovered, so that the conical rod (20) is completely pulled out from the ground, and the fixed positioning operation of the device is released;
s8: the moving operation of the bridge construction concrete prefabricated part can be conveniently realized through the roller (28), and the use is convenient.
