Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0033] Please refer to Figures 1-7 , the present invention provides a technical solution: a high-speed railway turnout laying machine, including a mechanical main frame 1 and a turnout body 6. A rectangular acquisition board 8 is installed on the lower side of the mechanical main frame 1. A plurality of picture acquisition components are evenly installed on the rectangular acquisition board 8 at equal intervals. The plurality of picture acquisition components form a picture acquisition matrix, which can acquire road surface picture information with the same size as the rectangular surface on the rectangular acquisition board 8. The following are provided on the mechanical main frame 1:

[0034] A clamping member 9, a discharging unit is arranged at the bottom of the clamping member 9. The discharging unit can be clamped on the surface of the curved turnout body 6, and the clamping angle of the discharging unit can be adjusted by 360 degrees. Infrared sensors 13 are fixedly installed at the upper ends of the clamping members 9;

[0035] An adjusting unit, which is composed of a transverse adjusting member and a longitudinal adjusting member. The transverse adjusting member can move on the longitudinal adjusting member, and the clamping member 9 can move on the transverse adjusting member.

[0036] During operation, the mechanical main frame 1 in the present invention drives the turnout body 6 to move to the installation position. At this time, the actual installation sleeper of the turnout body 6 is below the mechanical main frame 1. Through the picture acquisition matrix formed by a plurality of picture acquisition components on the rectangular acquisition board 8, the road surface information below the mechanical main frame 1 is acquired. The picture information acquired by the plurality of picture acquisition components is spliced into a road surface picture with the same size as the rectangular surface on the rectangular acquisition board 8. At this time, the straight track and the turnout body 6 on the clamping member 9 are within this rectangular picture. Combining the laying design data of the turnout body 6, with the two sides of the rectangular picture as the X-axis and the Y-axis respectively, the installation position of the turnout body 6 relative to the straight track is determined within this rectangular picture. Two points are located within this installation position as the installation points of the turnout body 6. Then, the transverse adjusting member and the longitudinal adjusting member on the adjusting unit drive the clamping member 9 to move until the infrared sensors 13 on the clamping member 9 coincide with the installation points, thereby driving the turnout body 6 to the designed installation position. Then, the turnout body 6 is slowly placed through the clamping member 9, so as to be able to move the turnout body 6 to the specified installation position more efficiently and quickly, avoid the difficulty of manual handling, and improve the installation efficiency of the turnout body 6.

[0037] As a further solution of the present invention, the clamping member 9 includes a main mounting seat 12. A protective frame 14 is fixedly installed at the lower end of the main mounting seat 12. A rotating frame 15 is rotatably installed on the lower surface of the protective frame 14.

The clamping telescopic rod 19 is fixedly connected to the side connecting plate 21 and the free end is rotatably connected to the clamping block 20 through a spherical connecting seat. The two groups of clamping blocks 20 arranged symmetrically can approach from both sides of the turnout body 6 to clamp the turnout body 6.

[0038] During operation, in the present invention, the clamping member 9 clamps and fixes the turnout body 6 from both sides through the clamping blocks 20 arranged oppositely at the bottom. The designed curvatures of different turnout bodies 6 are different. The inclination angle of the clamping blocks 20 at the bottom of the clamping member 9 can be adjusted by 360 degrees, so as to be able to adapt to the clamping of the turnout body 6 with different curved surface radiances. Moreover, the turnout body 6 is fixed by two groups of clamping members 9 at the same time, and the positions of the two groups of clamping members 9 can both be adjusted to ensure that the clamping members 9 can be adapted to the clamping of the turnout body 6 with different curvature changes. After clamping, it can avoid the problem that the turnout body 6 is prone to dislocation and shaking during the movement when the turnout body 6 is transported by the previous long-strip rectangular limiting bin, and improve the stability of the turnout body 6 during the transportation process. In the present invention, the clamping block 20 is driven by the lifting telescopic rod 17 to move down to both sides of the turnout body 6, and the lower end of the clamping block 20 is driven by the clamping telescopic rod 19 to rotate around the side connecting plate 21, so that the clamping blocks 20 approach both sides of the turnout body 6 from both sides to clamp and fix the turnout body 6.

[0039] As a further solution of the present invention, the lateral adjusting member includes a transverse threaded rod 7 and a side mounting seat 11.

There are multiple sets of transverse adjusting members between the two sets of vertical threaded rods 10, and the upper ends of the mounting seats 11 on both ends of the transverse adjusting member are respectively threadedly connected to the two sets of vertical threaded rods 10.

[0042] During operation, the second motor drives the vertical threaded rod 10 to rotate. The vertical threaded rod 10 interacts with the side mounting seat 11, thereby driving the side mounting seat 11 to move vertically. By the movement of the side mounting seat 11, the transverse threaded rod 7 is driven to move. The transverse threaded rod 7 and the vertical threaded rod 10 are parallel to the two sides of the rectangular screen.

The central processor can mark the original straight track position on the road surface picture information with the same size as the rectangular acquisition board 8 according to the picture information, and determine the laying position of the turnout body 6 on the road surface picture information according to the turnout laying design data.

[0046] During operation, the picture information obtained by the picture acquisition member determines the installation position of the turnout body 1 on the rectangular screen according to the relevant data such as the distance between the straight track and the turnout in the turnout laying design data, which assists in determining the position of the straight track. This rectangular screen is set parallel to the actual road surface in a one-to-one ratio.
