The connecting device for bridge construction according to claim 2, wherein: the auxiliary rotating rod, the driven rotating rod and the driving rotating rod are distributed in a triangular mode, and the driven rotating rod is connected with the auxiliary rotating rod and the driving rotating rod through belts.
10. The construction method of the connecting device for bridge construction according to claim 1, wherein: the method comprises the following steps:
s1: the first servo motor is connected with a power supply to control the first servo motor to rotate forwards, the first servo motor controls a screw rod connected with an output end to rotate, the screw rod controls a lower workbench in outer side threaded connection to move upwards, and the distance between the lower workbench and an upper workbench is shortened until a lower driving wheel is attached to the lower side surface of the prefabricated bridge floor of the bridge;
s2: pushing the mounting rods backwards, and synchronously moving the calibration rods to enable the calibration rods to be overlapped with the transverse center line of the bridge prefabricated deck;
s3: pushing the connecting rod, controlling the placing tables arranged at the lower ends to move by the connecting rod, adjusting the distance between the 2 placing tables, enabling the moving distances of the 2 placing tables to be the same, fixing the moving frame by using bolts, fixing the connecting rod and further fixing the positions of the placing tables;
s4: the prefabricated bridge deck is placed on a placing table, the prefabricated bridge deck presses the placing frame, a second gear block arranged on the outer side of the placing frame controls a driving gear connected in a meshed mode to rotate, a driving rotating rod connected with the inner portion of the second gear block in a key mode controls a driven rotating rod connected with a belt to rotate, the driven rotating rod controls an auxiliary rotating rod connected with the belt to rotate, the auxiliary rotating rod controls an auxiliary gear connected with the outer side in a key mode to rotate, the auxiliary gear is connected with the first gear block in a meshed mode, therefore, the locking frame can be controlled to move towards the end portion close to the prefabricated bridge deck, and the prefabricated bridge deck is locked through the locking frame and the placing frame;
s5: the hydraulic cylinder is opened, the hydraulic cylinder pushes the sliding block to move leftwards, the sliding block controls the supporting rod connected in a hinged mode to rotate, the other end of the supporting rod rotates on the mounting rod connected in a hinged mode, so that the connecting frame can be controlled to rotate through the rotating shaft, the connecting frame controls the connecting rod to drive the placing table to move downwards, and therefore the prefabricated bridge deck can be moved downwards until the prefabricated bridge deck on the placing table is aligned with the prefabricated bridge deck of the bridge;
s6: and the second servo motor is powered on, and the lower driving wheel connected with the output end of the second servo motor is controlled by the second servo motor to rotate, so that the whole device is driven to move, and the bridge floor is connected.
