Furthermore, the two ends of the slide rail 14 are provided with pulley limiting plates 15, and the pulley limiting plates 15 prevent the sliding seat plate 13 from moving beyond the limit.
Example two
Referring to fig. 7 to 10, another structure of the moving driving assembly according to the present invention is a combination of a dual push rod and a sliding surface. The moving driving assembly comprises a longitudinal push rod 21 arranged at the rear end of the chassis 3 and a transverse push rod 27 arranged at the right side of the chassis 3. The longitudinal push rods 21 are parallel to the tube lane axis and the transverse push rods 27 are perpendicular to the tube lane axis. The piston end of the longitudinal push rod 21 is connected with the rear side of the sliding seat plate 13, so that the sliding seat plate 13 is pushed and pulled to move back and forth; the piston end of the transverse push rod 27 is connected with the right side of the sliding seat plate 13, thereby pushing and pulling the sliding seat plate 13 to move left and right.

When observing the pipe gallery festival section and the pipe gallery tail end condition of being close, adopt the displacement of the fine control pipe gallery festival section of remote controller.
The second embodiment of the mobile driving assembly further comprises a first heavy-duty universal ball array group 20 arranged on the upper surface of the vehicle chassis 3 or the bottom surface of the sliding seat plate 13. The first heavy weight array of universal balls 20 comprises a plurality of first heavy weight universal balls arranged evenly and densely. When the first heavy universal ball array group 20 is arranged on the chassis 3, the first heavy universal balls are fully distributed in the area on the chassis 3 for the sliding seat plate 13 to move. The lower surface of the sliding seat plate 13 is smooth, and the sliding seat plate 13 slides on the first heavy-duty universal ball array group 20. First heavy universal ball array group 20 sets up when sliding seat board 13 bottom, can assemble each first heavy universal ball in a set board earlier, and integral erection is in sliding seat board 13 bottom again. In this example, the support frame 3 is a flat and smooth surface, and the first heavy universal ball array 20 slides on the chassis 3. This structure realizes waiting to wait to manage the dual accurate positioning of position, left and right sides position around piping lane segment 2.
The connecting structure of the push rod and the sliding seat plate 13 is as follows: the rear side and the right side of the sliding seat plate 13 are respectively provided with a sliding chute 22, the sliding chute 22 comprises a box-shaped groove 22-1, and a plurality of second heavy universal balls 28 are arranged at the bottom of the box-shaped groove 22-1; the piston ends of the longitudinal push rod 21 and the transverse push rod 27 are respectively fixedly connected with a push plate 26, and the push plate 26 is arranged in the sliding groove 22 and is in sliding contact with a second heavy universal ball 28. When the push plate 26 with the structure pushes the sliding seat plate 13 and the load components thereon, the plate surface is pressed on the second heavy universal balls 28 at the same time, the heavy universal balls have strong load force, the second heavy universal balls 28 share the pressure together, and the pressure borne by each second heavy universal ball 28 is within the range of the load. When the push plate 26 moves in the slide groove 22, it slides on the surface of the second universal ball 28, so the push plate 26 has little resistance to move, and the slide seat plate 13 moves smoothly.

(2) With second pipe gallery (treat group to pipe gallery festival section 2) hoist to first pipe gallery rear, the position aligns along the central line with first pipe gallery, and the assembly car travels to second pipe gallery rear side from the inside inverse of first pipe gallery, makes climbing mechanism stop in second pipe gallery roof below, and wheel 4 stops on first pipe gallery bottom plate before assembling simultaneously, and back wheel 6 stops outside second pipe gallery.
(3) And opening a switch of the splicing vehicle tail supporting jack 8, and controlling a flange plate at the top of a piston rod of the jack to fall to a concrete cushion layer at the rear side of the second pipe gallery at a constant speed to restore the vehicle body to be horizontal.
(4) And opening a switch of the synchronous hydraulic jack (jacking jack 5), and slowly jacking the second pipe gallery to enable the second pipe gallery to be level with the top of the first pipe gallery.
(5) Placing one winch in front of the assembly vehicle, connecting one end of the winch with two steel wire ropes with equal lengths, hooking the other end of the winch on the traction hooks 18 at two ends of the synchronous hydraulic jack respectively, starting the winch, slowly drawing the jacking jack to slide forwards, and finally enabling the second pipe gallery to be tightly attached to the first pipe gallery to achieve accurate butt joint of the second pipe gallery.
(6) And repeating the steps until the whole section of the pipe gallery is spliced.
According to the invention, when the pipe gallery section 2 to be assembled is jacked, the pipe gallery section 2 is borne by the chassis 3, the front wheels 4 are left supporting feet of the chassis 3, the supporting jacks 8 are right supporting feet of the chassis 3, the distances between the two supporting feet and the pipe gallery section are basically the same, namely, when the pipe gallery is installed, the single-bin pipe gallery section is always positioned in the middle of the vehicle body, the supporting points on the two sides of the pipe gallery section are balanced, the vehicle body is ensured not to overturn due to overlarge load in the moving process of the pipe gallery section 2 to be installed, and the stability is kept.
The vehicle body structure is light in weight, small in size and large in bearing capacity.
The assembly vehicle is assembled in the pipe gallery segments, the supporting points on the pipe gallery segments are very close to the opposite sides of the pipe gallery groups, the action of the jack exerts an instant effect on the pipe gallery, an operator can easily observe the opposite butt joint condition of the groups, and then the displacement of the pipe gallery segments can be timely and accurately controlled, so that accurate butt joint control is realized.
The invention is suitable for the assembly engineering of the single-bin prefabricated pipe gallery, realizes accurate and quick butt joint of the pipe gallery, effectively improves the construction efficiency and the construction quality of the assembly of the single-bin prefabricated pipe gallery, and can be widely popularized in the field of the installation of the single-bin prefabricated pipe gallery.
