Example 1

The above-mentioned vehicle maintenance vehicle suitable for the air rail transit system is used for maintenance, and the vehicle to be overhauled is a suspended permanent magnet suspension rail transit system.

Referring to Figure 3, the bogie 51 of the vehicle to be repaired 5 is parked at the end interface of the train track beam, and the vehicle inspection vehicle is stably parked at the end of the train track beam, so that the rail steel plate and the track beam interface are docked, and the vehicle inspection vehicle is docked. Each group of column hydraulic rods 12 and each group of large hydraulic rods are stretched in place, the manual screw support rods 14 on the rail steel plate are stretched in place, and the hydraulic rollers 13 supported by the four steel beam columns are retracted into the beam arms supported by the steel beam columns or side.

Complete the preparatory work in the early stage, the bogie 51 of the vehicle 5 to be repaired is slowly pulled by the tractor traction or manual traction, etc., because the permanent magnet suspension train itself is in a vertical suspension state, and the horizontal direction is basically free from friction, so the overall train level Traction The train can move without requiring a large traction force. 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, at this time, the load of the train is still supported by the permanent magnet suspension module, but the extended carrying arm 511 of the permanent magnet suspension module is in the maintenance vehicle. Above the outstretched track steel plate, see Figure 3. Then, the maintenance personnel place the bearing wheel set 6 on the steel frame 31 of the maintenance console module 3 correspondingly on the rail steel plate extending outside the maintenance vehicle, and the hydraulic support shaft on the bearing wheel set 6 corresponds to the train bogie 51. Then, the hydraulic press on the bearing wheel set 6 is activated by a mechanical rocker or a mechanical remote control, and the hydraulic support shaft is gradually pushed up to the groove of the extending bearing arm 511 until the load on the left and right sides is lifted. The wheel set 6 completely replaces the permanent magnet suspension module of the bogie 51 of the train, and supports the load at the front end of the train, as shown in FIG. 8 .

Wherein, when the hydraulic press on the carrying wheel set 6 is started, the plastic wheel 61 of the carrying wheel set 6 is fastened to the wheel hub by the brake plate 63 and is in a braking state. In addition, a soft protective shell can be nested on the permanent magnet suspension module, which can not only protect the permanent magnet suspension module, but also effectively avoid the danger to the staff caused by the adsorption of the permanent magnet during the maintenance process. The adsorption of ferromagnetic tools under strong magnetism poses a real-time security threat to workers. At the same time, the driving permanent magnet stator installed on the top of the train still has strong magnetic properties. Therefore, when the bogie gradually pulls out the suspension beam of the train, a soft protective shell is nested in time, which acts as the soft protective shell of the permanent magnet suspension module. Like the protective case, it avoids the danger caused by the strong adsorption of ferromagnetic tools by the strong magnetic properties during the maintenance process.

After the front end of the load-bearing wheel set 6 is smoothly installed, the brake plate 63 of the plastic wheel 61 under the load-bearing wheel set 6 can be opened, and the traction makes the bogie 51 move forward along the track steel plate of the vehicle inspection vehicle. A plurality of groups of suspension modules are arranged in turn according to the first group of suspension modules to place the load-bearing wheel sets 6, as shown in FIG. 3, until all the permanent magnet suspension modules on the train bogie 51 are replaced by the load-bearing wheel sets 6 to support the train bogie 51 and the suspension. The full load of the car 52. Referring to FIG. 1 and FIG. 3 , the train bogie 51 and the suspension carriage 52 stay in the middle position of the vehicle maintenance vehicle. In addition, after the bogie 51 of the train is pulled to the predetermined position of the vehicle maintenance vehicle, the brake plates 63 of the plastic wheels 61 are fastened to the wheel hub, and fixed blocking buckles 64 are added to the front and rear of the carrying wheel set 61 to realize two layers of reinforcement to the bogie 51 , to avoid the occurrence of dangerous situations caused by factors such as tilt, see Figure 4.

When the load bearing wheel set 6 supports the train bogie 51, between the support shaft of the hydraulic jack 62 and the extended carrying arm 511 of the bogie 51, the hydraulic jack 62 and the extended carrying arm 511 are reinforced by fixing bolts to avoid The uneven force causes the bearing wheel set 6 to slip out or even fall off during operation, which can effectively avoid the heavy pressure on the hub of the plastic wheel 61 and the groove of the steel track plate caused by the unbalance of the bearing wheel set 6 friction, causing damage/damage of the plastic wheel 61, reducing the service life, etc.

When the bogie 51 of the train is stably parked on the track steel plate of the vehicle inspection vehicle, under the double fixation of the brake plate 63 of the plastic wheel 61 and the fixed blocking buckle 64, the manual screw supports are connected to the beams on both sides of the vehicle inspection vehicle.

In particular, it is only necessary to provide corresponding engaging buckles on the bogie 51 of the train.

In the implementation of the portable scaffold 32, the suspension carriage 52 of the train needs to be removed and hung, and the tractor is moved out of the operation space of the maintenance vehicle.

Specifically, first, the suspended carriage 52 is supported by the carrying panel 45 of the carriage hoist, and the tractor is pulled out of the carriage hoist to move to a designated position, so as to assemble the portable scaffold 32 to the top equipment box of the suspended carriage 52 and the internal air conditioner , display and other service equipment.

The use of the carriage crane is to place the carriage crane at the bottom of the suspension carriage 52. At this time, the height of the bottom of the suspended carriage 52 is higher than the height of the bearing panel 45 of the carriage crane. During the operation, the multiple groups of hydraulic support rods 451 of the bearing panel are slowly raised until the grooves of the bearing panel 45 correspond to the support pads of the suspended carriage 52, and the weight of the entire suspended carriage 52 is stably supported by the carriage lift truck. The hydraulic height is raised again, so that the relevant staff can smoothly remove the suspension link on the top of the suspension car 52 for connecting the suspension car 52 and the bogie 51, and then the tractor can pull the car to the designated position.

In particular, when it is necessary to maintain the lines/components under the condition that the top equipment box hanging on the top of the carriage 52 or the bottom of the bogie 51 cannot be reached, etc., the lines/components can be supported and pulled by the carriage crane and unloading truck. Operations such as moving the position of the suspended carriage 52 are performed, and then further maintenance of the mechanical structure is performed.
