The device realizes the functions of the invention through the following steps, thereby solving the technical problems provided by the invention:

the method comprises the following steps: during operation, the tower crane is started to enable the assembly equipment to be suspended to the top of the building component, and the two sides of the top end of the building component are fixedly connected with the lifting hook 5 through the steel wire pull rope, so that the building component is vertically parallel to the bearing duplex hydraulic slider 4 in the suspension process;

step two: the first electric hoist 1e and the second electric hoist 1f are controlled to enable the duplex double-rod suspension arm 1 to gradually lift the building component, so that the building component at the initial position is gradually lifted upwards in a horizontal posture, and the W-shaped steel wire lifting rope 2b enables the building component not to easily spin in the horizontal direction in the suspension process;

step three: the method comprises the steps that a first bearing pulley 1b and a second bearing pulley 1c are controlled to enable a building component to move to a target position to be assembled in a horizontal suspension state, a first electric hoist 1e and a second electric hoist 1f are controlled to put down the building component, when the building component is located at the target position for a certain distance, height or direction cannot be finely adjusted through a tower crane, accurate positioning and assembling are carried out, a first hydraulic cylinder 3c is started, an output shaft of the first hydraulic cylinder is slowly reset, the top end of the first hydraulic cylinder is abutted to an abutting edge 3b1 to vertically descend, a lifting block 3b is vertically descended relative to a frame 3a, and the building component is vertically and slightly descended; thereby facilitating docking;

step four: and starting the second hydraulic cylinder 4d and the third hydraulic cylinder 4e to enable the working ends of the second hydraulic cylinder 4d and the third hydraulic cylinder 4e to move along the same direction and the same stroke in the horizontal direction, so that the building component fixedly connected with the duplex working end of the bearing duplex hydraulic slider 4 moves along the same direction through the lifting hook 5, the positioning is more accurate, and the building component is accurately arranged at a target position to be assembled.

The foregoing has described the general principles, principal features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
