Description

Technical Field

[0001] The present application belongs to the field of magnetic levitation transportation technology, and in particular relates to a magnetic levitation engineering vehicle. Background Art

[0002] At present, in the field of maglev transportation, engineering vehicles are generally used to inspect and maintain the lines and facilities on the maglev tracks, and when a maglev train breaks down, engineering vehicles are used to rescue and tow the faulty maglev train.

[0003] Existing maglev transportation engineering vehicles are generally wheeled engineering vehicles, that is, engineering vehicles that use rubber wheels as running parts. Since the rubber wheels of wheeled engineering vehicles need to contact the track, the operating speed of wheeled engineering vehicles is not high, which cannot meet the inspection and maintenance needs of long-distance maglev lines. In addition, the adhesion coefficient of the rubber wheels of wheeled engineering vehicles is greatly affected by the state of the track surface. Water or ice on the track will cause the wheel-rail adhesion coefficient to drop sharply, which is prone to wheel slippage, making it impossible for the vehicle to exert normal traction and braking force, resulting in vehicle sliding, and the operation risk is relatively high.
