The hydraulic oil output by the hydraulic station 20 controls the jacking cylinder 101 to act, so that the jacking cylinder 101 jacks up, and the travelling wheels 103 are separated from the travelling track 2. Preferably, the positioning sensor 16 determines the jacking height through the auxiliary positioning target 22. For example, the sight of the position sensor 16 is aligned with the horizontal line in fig. 4. The positioning sensor 16 observes whether the alignment is aligned with the vertical line in fig. 4, if there is a difference, the hydraulic station 20 outputs hydraulic oil to extend and retract the piston rod of the deviation-correcting cylinder 18, so that the sliding seat 3 slides along the sliding beam 102 for fine adjustment until the alignment star of the positioning sensor 16 is aligned with the vertical line in fig. 4. After the sliding seat is in place, the deviation-rectifying limiting device 17 is adjusted to tightly push the sliding seat 3, so that the displacement in the installation process is avoided. The hydraulic station 20 controls the telescopic cylinder 4 to act, and the telescopic frame 5 slides forwards along the sliding seat 3 until the heavy construction 15 reaches the installation position, as shown in fig. 9. During the telescoping process, the telescoping distance is fed back by the distance sensor 21. The tilt angle of the attachment/detachment frame 8 can be finely adjusted by the tilt telescopic device 7 as necessary by observing whether or not the mounting position is reached. The transverse position of the loading and unloading frame 8 is finely adjusted by a deviation-rectifying limit device 17. The height position of the attachment/detachment frame 8 is finely adjusted by the lift cylinder 101, and the front and rear positions are finely adjusted by the telescopic cylinder 4. After the heavy construction 15 is installed in place. The jacking oil cylinder 101 controls the whole walking frame 1 to descend for a certain distance, and the telescopic cylinder 4 controls the telescopic frame 5 to move backwards for a certain distance, so that the barb device 14 is separated from the bearing pin 13. The jacking oil cylinder 101 continues to retract, the travelling wheels 103 fall onto the travelling rails 2 and travel to the initial position, and the installation operation of the heavy construction 15 is completed. As shown in fig. 10. The heavy structure 15 in this example comprises heavy elements such as end gates, fabricated shear walls, fabricated beams and fabricated columns which are not conducive to handling. When the lifting device is detached, the walking frame 1 is firstly walked to the mounting position, then the lifting oil cylinder 101 is matched with the telescopic cylinder 4 in a lifting mode to extend out for a certain distance, and the inclined cylinder 6 is adjusted to be at a proper inclination angle. The barb means 14 are connected to the bearing pin 13, the heavy construction 15 is substantially force-bearing on the handling frame 8, the connecting structure of the installation site of the heavy construction 15 is removed, the telescopic frame 5 is retracted and the heavy construction 15 is removed. The inclined cylinder 6 drives the loading and unloading frame 8 to return to the vertical state, the jacking oil cylinder 101 descends to drop the walking wheel 103 on the walking track 2, the walking wheel 103 drives the walking frame 1 to move to a hoisting position, and the hoisting device hoists the heavy construction object 15 from the loading and unloading frame 8, so that the whole operation of disassembling the heavy construction object 15 is completed. By adopting the rapid loading and unloading structure, the heavy construction 15 is converted from suspension cable hoisting to trolley accurate installation and disassembly, and the construction efficiency is greatly improved.
