Description
Technical Field
The invention belongs to the technical field of motor car equipment, and particularly relates to a system and a method for disassembling and assembling equipment under a reconnection type car, which are suitable for a movable car lifting jack.
Background
With the rapid development of the country, the rail traffic industry is also rapidly developing, and when the rail vehicle needs to be maintained, the whole train of the rail vehicle needs to be lifted to a certain height so as to replace a bogie at the bottom of the vehicle or other components mounted at the bottom of the vehicle. When the vehicle is overhauled, the carriage is lifted to a certain height by a fixed or movable car lifting machine and separated from the bogie, and particularly when the carriages of multiple cars are overhauled, a plurality of fixed or movable car lifting machines are needed, so that a plurality of marshalling synchronous lifting is ensured. After the bogie is separated from the carriage and transported away, the disassembly operation of the vehicle lower part is performed.
The movable car lifting jack is carriage lifting equipment arranged at two sides of the track bridge, after carriage bogie separation operation is carried out by using the movable car lifting jack, the track bridge is arranged below the carriage, the types and weights of the equipment and the parts under the carriage are different, and the space at two sides of the track bridge is limited, so that effective, stable and load-carrying disassembly space cannot be provided; in the disassembly and assembly operation of equipment under a maintenance workshop, the key is to provide a stable and load-bearing platform; in the working field environment, three places which can serve as bearing function are the track surface of the track bridge, the ground of the track bridge foundation pit and the ground outside the track bridge. At present, the existing domestic operation flow is rough, namely, a forklift is used, and the bottom of the equipment under the car is supported by a fork arm of the forklift, so that the equipment under the car is detached and installed. The existing operation mode is quite deficient in safety and operability, and firstly, the skill requirement and the attention requirement on operators of the forklift are quite high; secondly, the alignment problem of the mounting holes of the equipment is quite remarkable, and the forklift is often required to be repeatedly moved back and forth to align the mounting holes.
The prior patent document CN113200308A discloses a motor train unit under-vehicle component dismounting device with a lifting function; the device comprises a vehicle body and a wireless remote control system, wherein a conveying tray is arranged on the vehicle body and is arranged at the top of a lifting mechanism and used for receiving equipment under the vehicle; the lifting mechanism is positioned in the middle of the vehicle body and is used for lifting and dropping the conveying tray and the vehicle bottom equipment; the transverse moving roller tables are distributed on two sides of the lifting mechanism and used for bearing the conveying tray when the conveying tray descends to a transverse moving height; the rail clamping system is used for clamping the vehicle body on the rail bridge after the vehicle body is stopped; and the driving wheel system is used for driving the vehicle body to walk on the track bridge.

The disassembly and assembly equipment for the motor train unit under-vehicle components and the under-vehicle component transfer equipment matched with the disassembly and assembly equipment for the motor train unit under-vehicle components are required to be operated more than 20 key times in actual use, the sequence of the operation cannot be wrong, and collision or component drop can be caused.
