[0015] The walking system includes two sets of walking wheels 8, each set of walking wheels 8 is respectively arranged at the bottom of the lower longitudinal beam 3 of the two outer brackets;

[0016] The hoisting system includes four hoists 9, two of which are respectively arranged on the upper cross beams 7 of the two inner brackets;

[0017] The positioning system includes a longitudinal movement system and a transverse movement system; the longitudinal movement system includes a longitudinal movement rail 10 and a longitudinal movement motor 11, and the two vertical rods 6 of each inner bracket are respectively provided with a longitudinal movement rail 10 above the upper longitudinal beam 2 and the lower longitudinal beam 3 of the outer bracket in a direction parallel to the upper and lower longitudinal beams, and a longitudinal movement motor 11 is provided on the lower longitudinal beam and the upper longitudinal beam corresponding to each longitudinal movement rail, and the longitudinal movement rail 10 is supported on the longitudinal movement motor 11; the transverse movement system includes a transverse movement rail 12 and a transverse movement motor 13, and the transverse movement rail 12 is provided on the upper crossbeam 7 of each inner bracket, and the two winches 9 on the upper crossbeam are arranged on the transverse movement rail 12, and a transverse movement pulley is provided at the bottom of each winch, and a transverse movement motor 13 for driving the transverse movement pulley to move along the transverse movement rail is provided.

[0018] In the above structure, in order to ensure that the two inner brackets are installed between the two outer brackets, the spacing between the upper longitudinal beams of the two outer brackets can be set to be greater than the spacing between the two lower longitudinal beams; at the same time, in order to ensure the structural stability of the two inner brackets, at least one guide rod 14 can be passed through the two column brackets of each outer support frame, and the guide rod 14 passes through the vertical rods 6 opposite to the two inner support frames, and the two ends of the guide rod 14 are respectively fixedly connected to the two columns 1.

[0019] To ensure that the two inner brackets move stably along the lower longitudinal beams of the two outer brackets, a longitudinal sliding groove can be provided on each lower longitudinal beam in the longitudinal direction.

For large prefabricated blocks, the hoisting ropes on the two inner brackets can be directly connected to the prefabricated blocks, and one prefabricated block can be lifted at a time; for small prefabricated blocks, the hoisting ropes can be connected to the sling, and multiple lifting rings are set at the bottom of the sling, each of which can be connected to a prefabricated block, so that multiple prefabricated blocks can be lifted at a time.

[0024] The winch lifts the prefabricated block, and the integrated transfer and hoisting device carries the prefabricated block to the top of the installation location. Then, the horizontal position of the prefabricated block is accurately adjusted through the longitudinal and transverse systems of the positioning system. The winch lowers the prefabricated block and places it accurately at the installation location.

[0025] The travel system drive device returns to the transfer yard and lifts the next prefabricated block or a group of prefabricated blocks to the installation location for installation.
