1 and 6 , the upward movement of the piston rod of the hydraulic cylinder drives the installation sleeve 81 and the moving sleeve 71 to move upward, and the moving sleeve 71 moves upward under the action of the guide groove 26 and rotates downward toward the side away from the installation space 14 , so the moving sleeve 71 drives The supporting feet 72 and the supporting wheels 723 are moved up and away from the installation space 14, so that the supporting feet 72 and the supporting wheels 723 are turned to the outside of the installation space 14, and then the hoisting sling 32 can be moved down to put down the steel frame, thereby reducing the strength of the steel frame and the support. The probability of collision between the feet 72 and the supporting wheels 723 also reduces the probability that the supporting feet 72 and the supporting wheels 723 collide with the steel frame just put down when the moving frame 22 moves back and re-transports the steel frame.

The working principle of the embodiment of the present application is:

The steel frame is prefabricated and installed in advance, the moving motor 43 is activated to drive the hoisting and spreader 32 to move above the steel frame, and then the hoist 31 is started to lower the sling 311 to make the hoisting spreader 32 move down, so that the hoisting and spreader 32 is placed on the steel frame, and then Lower the suspending rope 311 so that the hook 53 extends into the steel frame, and then the hoisting sling 32 moves horizontally to drive the hook 53 to hook on the steel bars of the steel frame, and then the hoist 31 starts to drive the suspending rope 311 to move up to drive the hook 53 to move up, so that the hook 53 is pressed against the lower surface of the hoisting sling 32, and then the suspending rope 311 continues to move up to drive the steel frame to move up, and then the moving frame 22 moves to drive the steel frame to move horizontally, and when one end of the moving frame 22 moves to the outside of the support table 13, The movement of the hydraulic cylinder drives the moving sleeve 71 to move down, and the moving sleeve 71 moves down to drive the support feet 72 and the support wheels 723 to move toward the installation space 14 , so that the support wheels 723 are supported on the upper surface of the bridge after the pouring is completed, and the support motor 73 is activated to drive the support wheels 723 Turn, when the steel skeleton moves horizontally in place, the piston rod of the hydraulic cylinder moves up to drive the support feet 72 and the support wheels 723 to the outside of the installation space 14, then the steel skeleton can be put down, and then concrete is poured, so that the poured concrete and the poured finished The bridges are connected together, thereby improving the construction efficiency of the bridge, and the moving frame 22 is moved out of the support table 13 and then moved to the bridge after the pouring is completed for support, thereby improving the installation and stability of the steel frame during the hoisting process. Improve the efficiency of bridge construction, but also improve the safety of hoisting equipment.
