9. 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 powered on to control the first servo motor to rotate positively, the first servo motor controls the lead screw connected with the output end to rotate, the lead screw controls the lower workbench in threaded connection on the outer side to move upwards, and the distance between the lower workbench and the upper workbench is shortened until the lower driving wheel is attached to the lower side face of the bridge prefabricated deck;
s2: pushing the mounting rod backwards, and synchronously moving the calibration rod to enable the calibration rod to coincide with the transverse central line of the bridge precast deck;
s3: pushing the connecting rod, controlling the placement tables arranged at the lower end to move by the connecting rod, adjusting the distance between the 2 placement tables, enabling the moving distances of the 2 placement tables to be the same, fixing the moving frame by using bolts, fixing the connecting rod, and fixing the positions of the placement tables;
s4: the prefabricated bridge deck is placed on the placing table, the prefabricated bridge deck presses the placing frame, a second tooth 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 key of the second tooth block controls a driven rotating rod connected with a belt to rotate, a driven rotating rod connected with the belt is controlled to rotate, a secondary rotating rod connected with the outer key of the secondary rotating rod controls a secondary gear connected with the outer key to rotate, and the secondary gear is connected with the first tooth block in a meshed mode, so that a locking frame can be controlled to move towards the end portion close to the prefabricated bridge deck, and the prefabricated bridge deck is locked by 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 support rod in hinged connection to rotate, the other end of the support rod rotates on the installation rod in hinged connection, 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 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 switching on a power supply of the second servo motor, controlling the lower driving wheel connected with the output end of the second servo motor to rotate, driving the whole device to move, and connecting the bridge deck.
