[0022] Prefabrication: The pad stone is prefabricated through the pad stone steel mold, and the transverse positioning rod is fixed on the side surface of the pad stone steel mold;

[0023] Install the auxiliary tooling: clamp one side of the auxiliary tooling on the top surface of the pier steel formwork through the clamping slot, and then fix the auxiliary tooling on the surface of the pier steel formwork;

[0024] Debugging: The pull rod is driven upward by the rotating ring, so that the limit column and the limit rod are moved upward until the limit column is disengaged from the rotating limit slot and the limit rod is disengaged from the rotating plug-in slot, and then the rotating ring is rotated 90 degrees, and the rotating slide and the rotating slider are used to horizontally limit the rotating ring, and then the limit rod is pressed against the fixed block to cancel the rotation limit of the movable block, and then the total station is driven to rotate to the top of the bridge pier through the movable frame to measure the verticality of the auxiliary tooling and the distance between the two sets of auxiliary tooling, and then the positions of the two sets of auxiliary tooling are adjusted;

Then move the pad stone and the pad stone steel mold toward the pier steel mold. The pad stone steel mold first contacts the axial inclined surface and gradually enters between the two sets of auxiliary tooling through the cooperation of the axial inclined surface and the ball. Then the transverse positioning rod contacts the transverse inclined plate and cooperates with the ball through the transverse inclined plate to facilitate the movement of the transverse positioning rod toward the transverse positioning plate.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] The present invention drives the pull rod upward by the rotating ring, thereby causing the limit column and the limit rod to move upward until the limit column disengages from the rotating limit groove and the limit rod disengages from the rotating plug-in groove, then the rotating ring is rotated ninety degrees, and the rotating slide groove and the rotating slider cooperate to limit the rotating ring horizontally, and then the limit rod abuts against the fixed block, thereby canceling the rotation limit of the movable block, and then the total station is driven to rotate above the pier through the movable frame, so as to measure the verticality of the auxiliary tooling and the spacing between the two groups of auxiliary tooling, and then the positions of the two groups of auxiliary tooling are adjusted, and the pad stone steel mold and the pad stone are lifted by the lifting mechanism until the pad stone is located above the pier and the transverse positioning rod is located above the auxiliary tooling, and then the pad stone and the pad stone steel mold are moved toward the pier steel mold, and the pad stone steel mold first contacts the axial inclined surface, and is gradually moved by the axial inclined surface and the ball bearing cooperate with each other. It gradually enters between the two sets of auxiliary tooling, and then the transverse positioning rod contacts the transverse inclined plate, and the transverse inclined plate cooperates with the ball bearing to facilitate the transverse positioning rod to move toward the transverse positioning plate. When the transverse positioning rod contacts the longitudinal limit inclined surface, the longitudinal limit block is pressed into the limit groove until the transverse positioning rod contacts the bottom end surface of the transverse positioning plate. The limit spring holds the longitudinal limit block to limit the longitudinal position of the transverse positioning rod. The transverse positioning plate cooperates with the transverse positioning rod to limit the pad stone steel mold and the pad stone laterally. The two sets of auxiliary tooling limit the axial position of the pad stone steel mold, so that the pad stone is placed in the preset position to complete the installation of the pad stone. The transverse positioning rod and the auxiliary tooling are driven by the lifting mechanism to cooperate to achieve integrated lifting and fine-tuning, which saves a lot of time and improves the construction efficiency of the pad stone. The movable frame is used for fine-tuning and monitoring to assist in adjusting the pad stone into place. BRIEF DESCRIPTION OF THE DRAWINGS
