Description

Technical Field

[0001] The utility model relates to the field of motor vehicle body connection devices, in particular to a connection device for a lifting belt and a motor vehicle body. Background Art

[0002] EMU, or power vehicle, refers to vehicles equipped with power devices in rail transit systems, including locomotives and power cars. EMUs are equipped with driving wheels, while the corresponding vehicles without driving devices are trailers. For a train to run normally on the track, it must have an EMU to provide sufficient traction for the entire train, but it does not need to be attached to a trailer without power.

[0003] The existing EMUs need to move along designated roads via tracks when in use. However, they need to be hoisted onto tracks after production. When the EMU is damaged or in danger, they need to be hoisted to complete the transfer of their positions. However, traditional EMUs do not have a hoisting connection structure, resulting in the hoisting belt only being able to pass through the bottom of the EMU during the hoisting process. There are no hoisting buckles, which causes positional displacement during hoisting and causes dents and damage to the surface of the EMU, affecting the use of the EMU body. Utility Model Content
