(1) arranging a lifting base 3 in an area to be operated, fixing the position of the lifting base by using a steel plate connecting piece, controlling a hydraulic oil cylinder 3.5 in the lifting base 3 to fall back by using an oil pump, so that a lifting platform 3.4 is lowered to the bottom, and placing a lifting frame 2 above the lifting platform 3.4 along an opening on the side of the lifting base 3; after the arrangement is finished, the hydraulic oil cylinder 3.5 is lifted by using the oil pump, at the moment, as the hydraulic oil cylinder 3.5 is lifted, the lifting steel cable 3.8 moves upwards, the lifting platform 3.4 is restrained by the pulling force of the lifting steel cable 3.8 and the lifting pulley 3.9 in the guide rail 3.6, the lifting platform 3.4 carries the lifting frame 2 to lift, and in the process of lifting, the inclined plane below the elastic positioning pin 3.3 is stressed, so that the elastic positioning pin 3.3 moves towards the inside of the telescopic limiting part 3.2, and the lifting of the lifting frame 2 is not influenced; when the top of the lifting frame 2 exceeds the lifting base 3, the hydraulic oil cylinder 3.5 stops working and suspends lifting, at the moment, the self-walking rail car 1 is lifted to the top end of the lifting frame 2 by using a lifting tool, the hydraulic oil cylinder 3.5 continues working after the lifting frame is fixed by using a bolt, the lifting platform 3.4 rises until the elastic positioning pin 3.3 crosses the angle steel at the bottom of the lifting frame 2, at the moment, the elastic positioning pin 3.3 is popped out by the thrust of the internal spring 3.3.1 of the telescopic limiting part 3.2, at the moment, the hydraulic oil cylinder 3.5 is controlled to fall back, and the lifting platform 3.4 falls back until the lifting frame 2 is placed on the plane above the elastic positioning pin 3.3.
(2) Make lift platform 3.4 fall back to the bottom, at the side opening part that promotes base 3, put into its inside lift platform 3.4 with second lifting frame 2, control lift platform 3.4 slowly to rise this moment, make the location bolt 2.2 of first lift frame 2 bottom insert in second lift frame 2 top, lift platform 3.4 stops rising this moment, insert the bolt in location bolt 2.2 this moment, make first lift frame 2 and second lift frame 2 accomplish fixedly, after fixed, steerable lift platform 3.4 continues rising, when repeating above-mentioned operation until the suggestion is close the predetermined height after two photoelectricity correlation module group range finding, adjust lift platform 3.4 height, make the corresponding span of lift frame 2 fall on elastic locating pin 3.3, in order to reach the effect to the fine setting of device overall height. After reaching the preset height, the remote controller is used for controlling the horizontal motor 1.7 and the transverse moving motor 1.3 to enable the hoisting motor 1.9 to reach the preset position to finish the hoisting operation. The operation condition of the lifting device is monitored through laser radar ranging in the whole operation process.
(3) During the dismantlement, lift platform 3.4 and to last lifting frame 2 below, and lift it slightly, pull operating handle 3.7 outside this moment, elastic locating pin 3.3 receives the pulling force and inwards removes this moment, rotate operating handle 3.7 and rotate ninety degrees this moment, make spacing 3.7.1 stagger with spacing hole 3.2.1, make lifting frame 2 not receive the resistance of elastic locating pin 3.3, lifting platform 3.4 continuously descends and after elastic locating pin 3.3 is crossed completely to lowermost lifting frame 2, pull out operating handle 3.7 and continue to rotate ninety degrees, make elastic locating pin 3.3 unblock pop out. At this time, after the second lifting frame 2 is placed on the elastic positioning pin 3.3, the lifting platform 3.4 is lifted slightly, the bolt hole at the position of the positioning bolt 2.2 in the middle of the two lifting frames 2 is loosened, the lifting platform 3.4 is continuously lowered till the bottom, the lifting frame 2 is taken out from the inside of the lifting base 3, and the steps are repeated. And (3) until the self-walking rail car 1 descends to a position close to the upper part of the lifting base 3, unlocking a fixing bolt between the self-walking rail car 1 and the lifting frame 2, and continuously dismantling the lifting frame 2 after the self-walking rail car 1 is taken down from the upper part.
