The end of the adjusting bolt 14-1 is propped against a bolt sliding block 14-4 embedded in the U-shaped plate 14-3 to adjust the movement of the bolt sliding block 14-4. The pressing bolt 14-2 penetrates through a through hole on the bolt sliding block 14-4 to press the U-shaped plate 14-3 on the supporting upper plate 12. The U-shaped plate 14-3 is clamped to the two cross members of the bracket 13 to secure the bracket 13 to the supporting upper plate 12. The front beam of the bracket 13 is provided with a support column 15.
The invention is mainly used for transporting large parts, before transportation, the bracket 13 is required to be assembled on a large part transporting and assembling vehicle of a high-speed rail vehicle box, the large parts are placed on the bracket 13, and the bracket 13 is moved, so that the center of gravity of the large parts and the bracket 13 is positioned at the center of the cross universal joint 8.

The height of the high-speed rail car box large part transportation assembly vehicle is reduced, the high-speed rail car box large part transportation assembly vehicle is pushed to an assembly position, and a single brake sheet on the side edge of a universal wheel of the hydraulic lift truck 1 is stepped down, so that the high-speed rail car box large part transportation assembly vehicle is fixed in position on the horizontal plane.
The lifting pedal of the hydraulic lift truck 1 is stepped down at a constant speed. The lifting force is transmitted to a large part through the working platform of the hydraulic lift truck 1, the lower supporting plate 2, the universal joint cross 8, the upper supporting plate 12 and the bracket 13. During this process, the large components approach the mounting location gradually.
After detecting that the clearance gap meets the installation requirement, the pressure relief button of the hydraulic cylinder is pressed, and the support part 7 applies a supporting force N perpendicular to the contact surface to the supporting upper plate 122So that the support upper plate 12 starts to rotate about the cross joint 8 to return to the original position. Meanwhile, the whole large-part transportation assembly vehicle for the high-speed rail vehicle box descends to the lowest position of the vehicle at a constant speed.
When the upper surface of the large part is in contact with the mounting surface, the mounting surface applies a reaction force F to the large part perpendicular to the inclined mounting surface. The reaction force F is transmitted to the supporting upper plate 12. The upper support plate 12 starts to tilt and rotates about the central axis of the universal joint cross 8. The support part 7 applies a supporting force N to the supporting upper plate 12 perpendicular to the contact surface2The cross universal joint 8 exerts a supporting force N which supports a vertical contact surface of the upper plate 121. The tilting of the supporting upper plate 12 brings the large part to tilt in the same angular position. Final large part upper surface and high-speed passenger carThe bottom mounting positions are parallel and the whole device is in a balanced rest state as shown in fig. 5.
And detecting whether the gap between the upper plane of the large part and the bottom mounting surface of the high-speed passenger car meets the requirement by using intelligent detection equipment. During assembly of the large components, the inclination angle β of the support upper plate 12 is calculated:
in the formula Z1，Z2，Z3The vertical height measured by the device at the middle point of any three sides in the periphery of the lower supporting plate 2 is intelligently detected, and whether the inclination angle β meets the requirement of the inclination angle of the installation surface is compared.
