In this way, two device components are a group, are located on the both sides of vehicle needing hoisting and transporting, and according to the actual length of vehicle, multiple device components can be set up according to the gap. The lifting ring is used for connecting with the pull rope, and it is convenient for hoisting and transporting. After vehicle transportation is in place, place in place, then two rotates spacing rod 11 are twisted to the outside, so that the spacing contact of the corresponding beam or bar of vehicle, and rail transit vehicle can be separated from the device. The hoist and transport device for rail transit vehicle production, simple structure, quick assembly and disassembly, light weight, convenient to carry, can effectively realize hoisting and positioning in the transportation process of rail transit vehicle, reduce the stress deformation of transport product, and be suitable for different rail transit vehicle models.

[0025] Device component 1 includes multiple groups, and each device component 1 includes left device component and right device component, and the left device component and the right device component are arranged symmetrically. Each device component includes two main body frames, and the two main body frames 12 of each device component 1 are located on the both sides of vehicle needing hoisting and transfer, and connection ensures stable hoisting.

[0026] The inner side of the main frame 12 of the left device assembly of each device assembly 1 and the inner side of the main frame 12 of the right device assembly are connected by the transverse pull rod 4. The above structure realizes reliable connection of the two main frames of each device assembly by the transverse pull rod, and ensures stability.

The inner ring of the tie rod sleeve 8 has a double-threaded structure. This structure allows for variations in the length of the transverse tie rod. The first and second tie rod screws do not rotate. However, when the tie rod sleeve 8 is rotated in different directions, because of the double-threaded structure of the inner ring of the tie rod sleeve 8, the two tie rod screws simultaneously retract inward or extend outward, allowing for convenient and reliable adjustment of the length of the transverse tie rod 4. Screws can be installed near each end of the tie rod sleeve 8 for tightening and positioning the corresponding tie rod screws. When tightened, the screws abut against the smooth part of the corresponding tie rod screw to prevent damage.

When transferring a corresponding rail transit vehicle, each device component needs to be connected to a different part of the rail transit vehicle to ensure the stability and safety of the vehicle lifting during the transfer process. A clamping fixture 2 is provided on the upper part of the main frame 12 of the device component 1. The clamping fixture 2 includes two limiting platforms 10 and two rotating limiting rods 11. The two limiting platforms 10 are arranged with a gap between them, and the two rotating limiting rods 11 are arranged symmetrically. Each rotating limiting rod 11 extends into the limiting gap between the two limiting platforms 10. When connecting device component 1 to the rail transit vehicle, first turn the two rotating limiting rods 11 outwards so that the corresponding beams or rods of the vehicle fall into the gap between the two limiting platforms 10. Then, turn the two rotating limiting rods 11 inwards so that they are positioned above the beams or rods of the vehicle, thus limiting the beams or rods and connecting device component 1 to the vehicle, facilitating subsequent lifting. A transverse tie rod 4 is connected to the inner side of the main frame 12, and a lifting ring 3 is connected to the upper part of the main frame 12. Thus, two device components form a group, located on both sides of the vehicle to be lifted and transported. Multiple groups of device components can be set according to the actual length of the vehicle, with spacing between them. The lifting ring is used to connect with the pull rope for easy lifting and transport. After the vehicle is transported to its position, place it in place, and then turn the two rotating limiting rods 11 outwards so that the corresponding beams or rods of the vehicle are in limiting contact, allowing the rail transit vehicle to separate from the device.
