Movable vehicle body supporting body suitable for different vehicle types of rail transit and unwheeling method

Abstract

The invention discloses a movable vehicle body supporting body suitable for different vehicle types of rail transit. The movable type vehicle body supporting body comprises a vehicle body frame, a supporting seat, lifting devices and moving devices, wherein the supporting seat comprises a supporting column and a supporting bottom plate, the supporting column is fixed on the upper surface of the supporting bottom plate, the supporting bottom plate is located below a vehicle body framework, the supporting column penetrates through the middle of the vehicle body framework and protrudes upwards, and a positioning device matched with the parking space of the rail transit vehicle body frame is arranged at the top end of the supporting column; the multiple lifting devices are fixedly arranged onthe vehicle body frame, and the lifting devices penetrate through the main structure of the vehicle body frame and extend downwards to be connected with the supporting bottom plate of the supporting seat and are distributed at the periphery of the supporting column and are used for lifting the supporting seat between a working state position where the supporting bottom plate is supported on the ground and the moving walking state position where the supporting bottom plate is suspended on the ground. The universal train body supporting equipment can be used for carrying out movable supporting on different vehicle bodies, and is simple in structure, convenient to use and low in manufacturing cost.

Description

technical field [0001] The invention belongs to the field of train maintenance, and in particular relates to a mobile car body supporting structure capable of supporting different types of rail transit vehicle bodies such as high-speed rail, subway, city area, and maglev. Background technique [0002] With the rapid development of my country's rail transit, the maintenance of trains will gradually increase, and the demand for maintenance process equipment will also increase. In the process of large frame repair or advanced repair, the train needs to be disassembled and disassembled. After the vehicle is disassembled, it is necessary to use supporting equipment to temporarily support the car body so as to enter the follow-up maintenance work. [0003] In the field of traditional wheel-rail rail transit, when the vehicle is disassembled, the car body is separated from the bogie, and then the car body is mainly supported by the technical bogie. However, the process bogie costs...

AI Technical Summary

Problems solved by technology

However, the process bogie cost is high, and it can only support the corresponding vehicle body. Different models need to be equipped with different process bogies, which cannot support the car bodies of different models, and the versatility and economy are poor.
