Example 1
The vehicle maintenance vehicle suitable for the air rail transit system is used for maintenance, and the vehicle to be maintained is a suspended permanent magnet suspension rail transit system.
Referring to fig. 3, a bogie 51 of a vehicle 5 to be overhauled is parked at a tip interface of a train track beam, a vehicle maintenance vehicle is stably parked at the tip of the train track beam, so that a track steel plate is butted with the track beam interface, each group of upright hydraulic rods 12 and each group of large hydraulic rods of the vehicle maintenance vehicle extend in place, a manual spiral support rod 14 on the track steel plate extends in place, and hydraulic rollers 13 supported by four steel beam uprights are retracted into a beam arm supported by the steel beam uprights or one side of the beam arm.
The preparation work in the early stage is completed, the bogie 51 of the vehicle 5 to be overhauled is slowly pulled by the traction of a tractor or the drive of manual traction and the like, and the permanent magnet suspension train is in a vertical suspension state and basically does not receive friction force in the horizontal direction, so that the train can move without needing large traction force in the horizontal traction of the whole train. When the front end of the bogie 51 enters the joint between the rail steel plate of the vehicle maintenance vehicle and the train rail beam, the load of the train is still supported by the permanent magnet suspension module, but the extension bearing arm 511 of the permanent magnet suspension module is positioned above the rail steel plate extending outside the maintenance vehicle, see fig. 3. Then, a maintenance worker correspondingly places the bearing wheel set 6 on a steel frame table 31 of the maintenance operation table module 3 to a rail steel plate extending outside the maintenance vehicle, a hydraulic support shaft on the bearing wheel set 6 corresponds to a groove of an extending bearing arm 511 of a bogie 51 of the train, then a hydraulic machine on the bearing wheel set 6 is started through a mechanical rocker or a mechanical remote control and the like, the hydraulic support shaft is gradually jacked to the groove of the extending bearing arm 511 until the bearing wheel sets 6 on the left side and the right side completely replace a permanent magnet suspension module of the bogie 51 of the train, and the load at the front end of the train is supported, which is shown in fig. 8.
Wherein, at the moment of starting the hydraulic press on the bearing wheel set 6, the plastic wheel 61 of the bearing wheel set 6 is fastened on the wheel hub by the brake plate 63 and is in a braking state. In addition, the soft protective shell can be embedded in the permanent magnet suspension module, so that the permanent magnet suspension module can be protected, and the danger problem to workers possibly caused by the adsorption effect of the permanent magnet in the maintenance process can be effectively avoided, for example, the adsorption of the permanent magnet to a ferromagnetic tool under strong magnetism of the permanent magnet threatens the safety of the workers in real time. Meanwhile, the driving permanent magnet stator arranged at the top of the train still has strong magnetic characteristics, so that when the bogie gradually pulls out the suspension beam of the train, the soft protective shell is embedded in time to act as the soft protective shell of the permanent magnet suspension module, and the danger caused by the strong magnetic characteristics to the strong adsorption effect of the ferromagnetic tool in the maintenance process is avoided.
