The use process of the assembled car is explained in detail by combining a specific construction embodiment as follows:

(1) In earlier stage with conventional method with first section piping lane hoist and mount take one's place, the utility model discloses inside assembly car circular telegram back went into first section piping lane along the pipe coupling midline, back wheel 6 stopped on first section piping lane bottom plate.

(2) Hoist second pipe gallery (treating group to pipe gallery festival section 23) to first pipe gallery rear, the position aligns along the central line with first pipe gallery, the assembly car travels to second pipe gallery rear side from first pipe gallery inside, make climbing mechanism stop in second pipe gallery roof below, wheel 5 stops on first pipe gallery bottom plate before assembling this moment, rear wheel 6 stops on second pipe gallery ground outside, because the pipe gallery bottom plate has same thickness, there is the difference in height around the automobile body stops, the vehicle bottom dish, jacking jack's jacking face slope.

(3) And opening a switch of the second motor 3, uniformly dropping the piston end of the support jack 14 at the tail part of the spliced vehicle, and finally pressing the piston end against a concrete cushion layer at the rear side of the second pipe gallery to support the rear wheel 6 so as to enable the vehicle body to restore to the horizontal state.

(4) And the second pipe gallery is slowly jacked up by switching on and off the synchronous hydraulic jack (jacking jack 7), so that the second pipe gallery is separated from the concrete cushion.

(5) The traction rope is pulled out of the traction rope roller and hung on the traction hook, then the switch of the traction motor 11 is turned on, the traction motor is slowly pulled, the jacking jack moves forwards, and finally the second pipe gallery is tightly attached to the first pipe gallery.

(6) Slowly contract jacking jack 7, make second festival piping lane fall to the ground, realize the accurate butt joint of second festival piping lane.

The above steps are repeated for the third and fourth pipe sections, the single cabin of the last pipe gallery after splicing can be called as the tail end 22 of the pipe gallery, and the single cabin of the next pipe gallery to be installed can be called as the pipe gallery section 23 to be assembled. The utility model discloses the assembly vehicle is with the mode that backs up to remove in the piping lane.

As another embodiment of the moving mechanism, referring to fig. 4 to 6, the present invention provides another moving driving assembly structure, which includes a longitudinal push rod 18 installed at the rear end of the chassis 1 and a transverse push rod 19 installed at the right side of the chassis 1. The longitudinal push rods 18 are parallel to the tube lane axis and the transverse push rods 19 are perpendicular to the tube lane axis. The piston end of the longitudinal push rod 18 is connected with the rear side of the sliding seat plate 8, so that the sliding seat plate 8 is pushed and pulled to move back and forth; the piston end of the transverse push rod 19 is connected with the right side of the sliding seat plate 8, so that the sliding seat plate 8 is pushed and pulled to move left and right. The longitudinal push rod 18 and the transverse push rod 19 are respectively provided with a motor 20. This structure realizes waiting to organize dual accurate positioning of position, left and right sides position around piping lane festival section 23 through two push rods of horizontal, longitudinal arrangement.

In this embodiment, the terms "front end", "rear end", "front side" and "right side" used to define the setting position of the push rod are only used for convenience of description and are not intended to limit the technical solution.

The cooperation structure of above-mentioned pulley, slide rail is in order to reduce the frictional force when waiting to organize the piping lane festival section and remove. In a dual-movement solution, the present invention provides a friction-reducing solution that accommodates multi-directional movement. Specifically, a plurality of heavy universal balls 21 are densely arranged in a moving area of the sliding seat plate 8 on the chassis 1, and the sliding seat plate 8 slides on the heavy universal balls 21. The lower surface of the sliding seat plate 8 adopts a flat and smooth plate surface.

The concrete connection structure of the push rod and the sliding seat plate 8 is shown in the figure, sliding grooves can be respectively arranged on the rear side and the right side of the sliding seat plate 8, the end part of the push rod is arranged in the sliding groove 22, and in order to reduce the friction force between the push rod and the sliding groove, a plurality of heavy universal balls 21 can be also arranged in the sliding groove.

When considering the push rod to push away sliding seat board 8, be linked four jacking jack 7 with treat that the group is to piping lane segment 23, thrust is great, can directly bear by sliding seat board 8 is whole for making the push rod to sliding seat board 8's effect, set up on sliding seat board 8 rather than integrative welded cross reinforcement frame, press in the cross reinforcement frame outer end when the push rod is used, this scheme push rod thrust is strengthened the frame direct conduction by the cross to sliding seat board 8 wholly, reduces the pressure that receives of welding seam.

The longitudinal push rod 18 and the transverse push rod 19 are electric push-pull hydraulic cylinders with remote controllers, and the remote controllers respectively control the power supplies of the two motors 20 so as to control the extension and contraction of the corresponding push rods. When observing the pipe gallery festival section 23 of waiting to be organized and the pipe gallery tail end 22 condition of being close, adopt the displacement of the fine control pipe gallery festival section of remote controller.

The utility model discloses treat at the jacking and bear by vehicle chassis 1 when group 23 to piping lane festival section, preceding wheel 5 is vehicle chassis 1's left side supporting legs, and support jack 14 is vehicle chassis 1's right side supporting legs, and two supporting legs are the same basically with the distance of piping lane festival section, also namely when the installation piping lane, and single storehouse piping lane festival section is in the middle part of automobile body all the time, and the supporting point in piping lane festival section both sides is balanced, guarantees to treat that installation piping lane festival section 23 removes the in-process automobile body and can not topple because of the load is too big, and the holding is stable.

The utility model discloses the assembly car is in the piping lane festival section, and the strong point on the piping lane festival section is very close to the piping lane group face to face, and the action of jack produces instant effect to the piping lane, and the operator observes the butt joint condition face to face easily, then can be timely, the displacement of accurate control piping lane festival section, realizes accurate butt joint control.

The utility model discloses body construction lightweight, small and the bearing capacity is big.
