The second motor is mounted on the mounting base. The second gear is mounted on the output shaft of the second motor and meshes with the second rack.

7. The forming method of the beam top slab reinforcement cage structure according to claim 3, characterized in that, The clamping mechanism includes a base plate, a fixed clamping jaw, and a movable clamping jaw. A driving member is provided on the base plate. The fixed clamping jaw is disposed on the base plate. One end of the movable clamping jaw is connected to the driving member, and the other end forms a clamping groove between it and the fixed clamping jaw for inserting a reinforcing bar. The driving member is used to drive the movable clamping jaw to move so that the size of the clamping groove can be changed.

8. The method for forming the beam top slab reinforcement cage structure according to claim 7, characterized in that, The movable gripper has a hook at its end, and the gripping groove is formed between the hook and the end of the fixed gripper. The hook has a recess on the side facing the fixed gripper.

9. The method for forming the beam top slab reinforcement cage structure according to claim 8, characterized in that, The fixed gripper has an L-shaped structure, with one end connected to the base plate and the other end bent and extended towards the hook head; there are two fixed grippers arranged in parallel and spaced apart, and the movable gripper is slidably disposed between the two fixed grippers.

10. The forming method of the beam top slab reinforcement cage structure according to claim 2, characterized in that, When expanding the opening end of the stirrup, the opening size of the stirrup after expansion should be larger than the distribution size of the upper and lower layers of longitudinal reinforcement, so that the stirrup can be moved laterally along the top plate of the beam and placed on the longitudinal reinforcement. After the stirrup is positioned, the upper and lower layers of longitudinal reinforcement and the stirrup are welded together by the welding host of the assembly welding station. Then the longitudinal reinforcement is pushed forward a certain distance as a whole to meet the placement operation of the next stirrup.
