Description

Technical Field

[0001] This utility model relates to the field of vehicle rescue technology, and in particular to a vehicle rescue transport vehicle. Background Technology

[0002] The linear motor bogie system of a vehicle mainly consists of a frame, wheelset axle box assembly, spring damping device, traction drive device, traction connection device, braking device, and auxiliary devices. Its main functions are to support the car body, transmit loads, enable the vehicle to smoothly traverse curves, transmit traction and braking forces, mitigate vibrations and impacts, and improve ride comfort. The traction drive device, the linear motor, is essentially a split and flattened rotary induction motor; therefore, its stator and rotor are parallel in the plane. The stator is installed under the vehicle, while the rotor (induction plate) is mounted on the track foundation. Given that the linear motor traction drive device of a linear motor vehicle is a linear motor laid flat and suspended at the bottom of the bogie, if the wheelset axle box assembly malfunctions, the confined space at the bottom of the bogie lacks specialized rescue equipment. Continued operation would prevent the faulty wheelset from rotating, leading to wheelset and track abrasion, potentially resulting in a serious safety hazard such as derailment.

[0003] Therefore, a vehicle rescue transport vehicle is provided to address the shortcomings of existing technologies. Utility Model Content

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] In this vehicle rescue transport trolley, when a wheelset on the vehicle bogie fails to rotate, rescue personnel use a specialized lifting device to lift the vehicle. Once the vehicle is lifted to the required installation height for the transport trolley, it is placed on the track and pushed under the faulty wheelset using a positioning rod. The lifting device is then used to lower the vehicle, and the positioning rod is used to adjust the position of the transport trolley, allowing the faulty wheelset to fall onto it. Adjusting shims are used to adjust the wheel height according to the wheel diameter, ensuring the faulty wheel flange is below the rail surface. The transport trolley then rotates in place of the faulty wheelset, allowing the disabled vehicle to be removed from the scene. This vehicle rescue transport trolley significantly improves rescue efficiency. Attached Figure Description
