[0028] Step 3: After the transport platform (4020) is raised to the specified position, the lateral transport mechanism (5001) and the posture adjustment mechanism (5004) drive the clamping mechanism (5006) to move to the clamping position; then the distance adjustment mechanism (5003) drives the longitudinal distance adjustment structure main structure (8016) to move to the same position as the lifting point; then the telescopic mechanism (5005) is extended to make the clamping mechanism (5006) descend to the lifting ring, and then the electric cylinder four (10013) and the electric cylinder five (10016) of the clamping mechanism (5006) are contracted to clamp the lifting ring;

[0029] Step 4: After clamping the lifting ring, the telescopic mechanism (5005) slowly contracts so that the prefabricated component stops contracting after being stressed, and then the cylinder fixing the prefabricated component on the transport platform (4020) contracts and separates from the prefabricated component; then the telescopic mechanism (5005) continues to contract until the prefabricated component is raised to a specified height; then the transverse transport mechanism (5001) and the posture adjustment mechanism (5004) transport the prefabricated component to the lifting position, and then the posture adjustment mechanism (5004) turns the prefabricated component to the correct direction; then the telescopic mechanism (5005) extends to lower the prefabricated component to the lifting position for alignment;

[0030] Step 5: After the lifting is completed, the lifting mechanism (3) returns to the lifting position to carry out the next lifting process. After completing the lifting of one floor, the lifting mechanism (2) continues to lift to the specified height to carry out the next lifting work;

[0031] Step 6: After the construction of the entire building is completed, the horizontal transportation mechanism (5001) moves to one end until it exits the entire construction building, and then the electric cylinder seven (11016) connected to the jacking frame (11018) is first lifted to fix the main structure (11015) of the jacking structure with the standard section (11014) of the next layer; then the upper standard section (11014) is pushed out by the electric cylinder six (11017) connected to the push-pull rod (11013); then the standard section (11014) is lifted to the transportation platform (4020) by the lifting mechanism (3), and then the electric cylinder six (11017) connected to the push-pull rod (11013) is retracted back to the original position, and then the electric cylinder seven (11016) connected to the jacking frame (11018) is retracted, and the whole structure descends, and this is repeated until it descends to the specified height.

[0032] The beneficial effects of the present invention are:

[0033] Compared with the prior art, the advantages and positive effects of the present invention lie in that the prefabricated components are transported from the ground to the clamping height through a multi-adaptable prefabricated component automatic fixed transportation platform, the prefabricated components are hoisted to the installation site in a correct posture with a high-freedom lifting mechanism, and the height of the building construction machine is raised and lowered through a jacking mechanism, thereby completing the construction of the building.

[0070] like Figure 12-14As shown, when fixing the staircase component, one end of the staircase component is tightly fitted with the bracket 4016, and then the electric cylinder 1 4012 on the cylinder support 1 4017 is extended to push the horizontal fixed structure main structure 4018 to clamp the prefabricated staircase component. When fixing other horizontal components, the horizontal component is placed on the bracket 4016, and then all the electric cylinders 1 4012 are extended to push the horizontal component fixed structure main structure 4018 to clamp other horizontal components. When fixing the prefabricated column, the prefabricated column is vertically placed in the middle of the transport platform 4020, and then the electric cylinder 2 4013 is extended to push the vertical component fixed structure main structure 4015 until the arc structure of the vertical component fixed structure main structure 4015 completely clamps the prefabricated column component. When fixing other vertical components, the vertical components are erected vertically in the middle of the transport platform 4020 and parallel to the bracket 4016. Then the electric cylinder 1 4012 on the cylinder support 1 4017 is extended to push the horizontal fixed structure main structure 4018 to clamp other vertical components. Then the electric cylinder 2 4013 is extended until the vertical components are completely clamped.

[0071] like Figure 14-15 As shown, when hoisting the prefabricated component, after the transport platform 4020 is raised to the designated position, the transverse transport mechanism 5001 and the posture adjustment mechanism 5004 move simultaneously, driving the clamping device 5006 to the clamping position, and then the distance adjustment mechanism 5003 drives the clamping device 5006 to move to the same position as the hanging point; then the telescopic mechanism 5005 extends, so that the clamping mechanism 5006 descends to the hanging ring of the prefabricated component, and then the clamping claw I 10012 and the clamping claw II 10017 of the clamping mechanism 5006 move toward each other, realizing the contraction of the clamping mechanism 5006 and clamping the hanging ring of the prefabricated component. When clamping the prefabricated staircase component, the telescopic mechanism 5005 on the same side is synchronously extended and retracted to adjust the length of the telescopic, thereby changing the height between the clamping mechanisms 5006, so that the staircase component is hoisted at a specific angle. When clamping the vertical component, it is necessary to use two clamping mechanisms 5006 located at diagonal corners to clamp the vertical component. The two clamping mechanisms 5006 located at diagonal corners are rotated to be in the same vertical plane as the two lifting rings of the vertical component through the posture adjustment mechanism 5004, and the clamping device is rotated to a position perpendicular to the lifting ring through the cooperation of gear three 9015 and gear four 10014.

[0072] The transverse transport mechanism 5001 drives the prefabricated components to be transported transversely along the track 2011; the upper ends of the posture adjustment mechanism 5004 are connected to the guide rail 5002 through friction wheels 7015 to drive the prefabricated components to be transported longitudinally along the guide rail 5002, and the lower side of the posture adjustment mechanism 5004 is connected to the distance adjustment mechanism 5003 to drive the distance adjustment mechanism 5003 to rotate so as to adjust the direction of the prefabricated components; the distance adjustment mechanism 5003 is connected to the clamping device, and the distance adjustment mechanism 5003 drives the clamping mechanism 5006 to move horizontally so as to adjust the horizontal distance between the clamping claws, and the telescopic mechanism 5005 adjusts the vertical distance between the clamping claws by contraction, so as to adapt to the clamping, transportation and docking operations of various prefabricated components.

[0073] The method of hoisting using one of the above hoisting equipment is as follows:

[0074] Step 1: When lifting is required, the electric cylinders 7 11016 connected to all the lifting frames 11018 are extended at the same time, so that the entire lifting equipment rises as the electric cylinders 7 11016 are extended, and the lifting is stopped when it rises to a certain height. The main structure 11015 of the lifting structure is fixed to the standard section 11014, and then the electric cylinders 7 11016 connected to the lifting frames 11018 are retracted. The standard section is then hoisted to the standard section support platform 11012 through the lifting structure 3, and then the electric cylinders 6 11017 connected to the push-pull rod 11013 are retracted, and the standard section 11014 is pulled into the installation position for fixing, completing a lifting process.

[0075] Step 2: After the prefabricated components are fixed on the transport platform 4020, the motor 1 3011 is operated to reel in the steel cable 3012 and raise the transport platform 4020 to the clamping position.

[0076] Step three: After the transport platform 4020 is raised to the specified position, the transverse transport mechanism 5001 moves along the track 2011, and the posture adjustment mechanism 5004 moves along the guide rail 5002, driving the clamping mechanism 5006 to move to the clamping position; then the lead screw 8012 and the lead screw 2 8015 of the distance adjustment mechanism 5003 rotate, driving the main structure 8016 of the longitudinal distance adjustment structure to move, so as to change the distance between the clamping mechanisms 5006 to make it the same as the lifting point position; then the telescopic mechanism 5005 is extended to make the clamping mechanism 5006 descend to the lifting ring of the prefabricated component, and then the electric cylinder four 10013 and the electric cylinder five 10016 of the clamping mechanism 5006 are contracted to clamp the lifting ring.

[0077] Step 4: After clamping the lifting ring, the telescopic mechanism 5005 slowly contracts so that the prefabricated component stops contracting after being stressed, and then the cylinder fixing the prefabricated component on the transport platform 4020 contracts and separates from the prefabricated component; then the telescopic mechanism 5005 continues to contract until the prefabricated component is raised to a specified height; then the transverse transport mechanism 5001 and the posture adjustment mechanism 5004 transport the prefabricated component to the lifting position, and then the posture adjustment mechanism 5004 is started, the shaft II 7013 rotates, and the prefabricated component is turned to the correct direction; then the telescopic mechanism 5005 is extended to lower the prefabricated component to the lifting position for docking.

[0078] Step 5: After the lifting is completed, the lifting mechanism 3 returns to the lifting position for the next lifting process. After completing the lifting of one floor, the lifting mechanism 2 continues to lift to the specified height for the next lifting work.

[0079] Step six: After completing the construction of the entire building, the horizontal transportation mechanism 5001 moves to one end until it exits the entire construction building, and then the electric cylinder seven 11016 connected to the jacking frame 11018 first jacks up a short distance to fix the main structure 11015 of the jacking structure with the standard section 11014 of the next layer; then the upper standard section 11014 is pushed out by the electric cylinder six 11017 connected to the push-pull rod 11013; then the standard section 11014 is lifted to the transportation platform 4020 by the lifting mechanism 3, and then the electric cylinder six 11017 connected to the push-pull rod 11013 retracts back to its original position, and then the electric cylinder seven 11016 connected to the jacking frame 11018 retracts, and the overall structure descends, and this is repeated until it descends to the specified height.

[0080] The present invention utilizes the transport mechanism 4 to transport the prefabricated components to the hoisting height, and then clamps the prefabricated components to the docking position through the clamping mechanism 5006 to realize the construction of the floor, and installs and fixes the standard sections one by one through the jacking structure to realize the purpose of jacking as the floor rises.
