Utilize this large pipeline hoist and mount transfer device to hoist large pipeline, as shown in fig. 8, in the piping lane, there is the condition that upper and lower layer pipeline erect, and upper pipeline need dodge, and the shaping is the pipe connection of arched bridge structure, when setting up this kind of pipeline, needs hoist mechanical tubes 320 and straight tube 310 respectively and combine, and its specific connection flow is as follows:

when the pipeline is constructed below an arch bridge-shaped pipeline, two special pipes and a straight pipe 310 need to be stacked, the special pipes are in a Z-shaped structure, the transport vehicle 100 is driven by electricity or an engine and the like as power, and sends an instruction to the state controller 130 through manually holding a remote controller, so that the stepping unit 120 can be driven to move forwards and backwards, the steering unit 110 can drive the transport vehicle 100 to turn and adjust the direction, and the transport vehicle 100 is an existing special vehicle for transporting on a construction site and is used for transporting the pipeline into the pipeline gallery to be paved;

the special pipe 320 on one side is installed, and stops when the transport vehicle 100 transports to the pipe end to be installed, the pipe support plates 650 on two sides are sleeved on two ends of one special pipe 320, at this time, the special pipe is in a flat lying shape, the frame bodies 600 on two sides are distributed in a staggered way, the frame bodies 600 on two sides move inwards along the longitudinal direction, meanwhile, the lifting unit 630 is used to drive the upper support 610 to rise, the hydraulic cylinder 661 lifts up the hoisting mechanism 400 corresponding to the lower support 620 to move up, at this time, the centering movement effect and the one-end moving-up effect are combined, so that the flat lying shaped special pipe 320 is converted from the flat lying shape to the vertical shape, two ends of the flat lying shaped special pipe are placed on the pipe support plates 650 at two sides in a one-high-one-low manner, the hoisting effect is as shown in fig. 7, the height of the integral special pipe 320 is adjusted by the four hoisting mechanisms 400, the hoisting mechanism 400 drives the steel wire disc 430 to wind the steel wire by using the driving motor 410, and further drives the pipe support plate 650 to lift, then, the lower end of the profile tube 320 is fitted to the end of the pipe at one end by moving the holder 600 in the longitudinal direction;

after a pipeline on one side is installed and moves to a right angle position of a frame body 600, a first combination block 420 and a second combination block 662 are combined in a colliding mode, then a combination unit 640 needs to be disconnected, namely, a person on the ground pulls an extended pull rope to pull a swing rod 647 to rotate, a buckle 643 rotates, the buckle disc 643 rotates to release the hooking relation with a buckle hook 648 on the other side, meanwhile, the buckle disc 643 rotates, the pull rod 644 on the same side is driven to reset under the action of a tension spring 646, the buckle hook 648 is ejected upwards, the buckle hook 648 is separated from a groove body of the deflection buckle disc 643 on the other side, the two sides are in a mutually separated state, and an L-shaped support can be driven to move downwards under the action of a hydraulic cylinder 661 to separate from the connection relation between a sliding piece and the sliding piece;

on the contrary, in the collision process, firstly, the clasps 648 on both sides are inserted into the buckle disk 643, the clasps 648 prop against the oscillating bar 647 to rotate the buckle disk 643, the clasps 648 are driven to pull back, and the effect of mutual hanging on both sides is formed by combining the groove body on the upper deflection buckle disk 643, and the supporting spring 645 props against the oscillating bar 647 to keep the hanging effect on both sides stable;

similarly, installing the special pipe 320 on the other side, and installing the special pipe 320 on the other side symmetrically in the same way as the above steps, so that the special pipes 320 on the two sides deviate from the axis of the connected pipeline by 3-5 degrees;

then the straight pipe 310 is installed, then the frame body 600 is restored to the lowest state, the pipe supporting plates 650 at two sides are sleeved at two ends of the straight pipe 310, then the straight pipe is jacked to the top of the lower frame 620 by using the hydraulic cylinder 661, at this time, the combining unit 640 at the top end of the hoisting mechanism 400 collides and is combined into a whole, at this time, the hoisting mechanism 400 is maintained at the L-shaped right angle of the frame body 600, the moving unit at the top drives the sliding part to move, namely, the hoisting mechanism 400 connected by using the combining unit 640 is driven to move, at this time, the moving action can separate the first combining block 420 and the second combining block 662 at the bottom end, so that the L-shaped frame is separated from the longitudinal constraint and moves along the moving state, in the moving process, the driving motor 410 in the hoisting mechanism 400 winds the steel cable to the shortest state, at this time, the pipe supporting plates 650 are placed between the steel wire discs 430 at two sides to stably support the pipeline lifting piece 300, and are conveyed to one end of the first special-shaped pipe to be aligned with the driving of the moving mechanism 500, then the frame body 600 moves left and right in a staggered manner, so that the included angle between one end of the straight pipe 310 and the end part of the special pipe 320 is between 170 degrees and 174 degrees, namely, the special pipe 320 on the two sides and the middle straight pipe 310 form a Z-shaped structure, after the pipe ends abut against each other, the frame body 600 moves left and right in a reset manner, so that the pipe ends of the special pipe 320 and the straight pipe 310 are driven to be squeezed and tightened, the straight pipe 310 is assembled between the pipe ends of the special pipe 320 on the two sides, and the construction of a set of arched bridge-shaped pipelines is completed.
