And until gyro wheel (502) conflict stand combination (2) outer wall, again control suspension (53) and gyro wheel (502) synchronous revolution for gyro wheel (502) can compress tightly at stand combination (2) outer wall, screw (58) are screwed afterwards, can realize the installation of direction wheelset (5) fixed.
5. The method of using the lifting system of the building demolition machine of claim 4, wherein: the method also comprises the following steps:
S7, the P layer is a layer to be disassembled, and the initial installation is carried out: the upper bearing beam (9) is arranged on the P layer, and the lower bearing beam (10) is arranged on the P-2 layer;
S8, loosening all locks of the lifting jack (4), wherein the lower bearing beam (10) bears all loads, and lifting the lifting jack (4) by a small section by using the electric hoist (3) arranged on the upper fixed connecting beam (202) to leave a layer P, and removing the layer P;
s9, the electric hoist (3) arranged on the upper fixed connecting beam (202) is used for descending the jacking jack (4) and the upper bearing beam (9) until the upper bearing beam (9) reaches the upper surface of the P-1 layer floor slab (8), then the jacking jack (4) is operated to perform jacking movement, so that the steel stranded wire (6) drives the whole upright column assembly (2) and the lower bearing beam (10) to leave the upper surface of the P-2 layer for a small distance through the lower fixed connecting beam (203), and the lower telescopic arms (1001) at two ends of the lower bearing beam (10) are retracted in the lower beam sleeve (1002), and at the moment, the upper bearing beam (9) bears all loads;
S10, operating the jack (4) to conduct descending until the lower bearing beam (10) passes through the P-2 layer operation hole (7) and reaches the upper surface of the P-3 layer for a small distance, and at the moment, the whole upright column assembly (2) and the top truss system (1) are also lowered by a distance of about one layer;
S11, lower telescopic arms (1001) at two ends of a lower bearing beam (10) extend out of a lower beam sleeve (1002), a lifting jack (4) is operated to conduct descending until the lower bearing beam (10) reaches the upper surface of the P-3 layer, at the moment, the upper bearing beam (9) and the lower bearing beam (10) bear loads together, and the steps are repeated, and the lifting jack descends layer by layer until the whole construction is completed.
