Damping levitation chassis disassembly device of maglev train

Abstract

The invention discloses a damping levitation chassis disassembly device of a maglev train. The device comprises a support column, a walking wheel component, a base, a lifting mechanism, a support platform, a lifting track, a left locking component, a right locking component and a damping component, wherein the damping component comprises a first thread sleeve, a screw rod, a handle, a force transfer cylinder, a second thread cylinder, a lifting cylinder, a transmission rod, a connection cylinder, a balancing weight and a plugging cover. According to the device, the d levitation chassis of the maglev train can be disassembled very conveniently; under normal circumstances, the device can serve as part of the track in a magnetic levitation shop to guarantee normal operation of the maglev train in an overhauling shop; based on the characteristic that resonance with the lower structure is easily generated by high-frequency adjustment of levitation gap in the levitation process of the maglev train, a middle support mechanism is provided and realizes a good damping effect; and meanwhile, to disassemble the levitation chassis of the maglev train, the lifting track can drive the levitation chassis of the maglev train to go down to facilitate the disassembly of the levitation chassis of the maglev train.

Description

technical field [0001] The invention belongs to the field of magnetic levitation equipment, and more specifically relates to a disassembly and assembly device for a suspension frame of a shock-absorbing magnetic levitation train. Background technique [0002] At present, China's medium and low-speed maglev transportation includes the National University of Defense Technology test line, the Qingchengshan test line and the Tangshan test line, and the Changsha maglev project was officially put into operation in June 2016. [0003] During the operation of the maglev vehicle, if it is found that there is a problem with the suspension frame of the maglev vehicle, it is necessary to drive the maglev vehicle to the inspection track for repair or replacement. The levitation frame of the maglev train is one of the core components of the medium and low-speed maglev train. After the train has run for a certain mileage, it must be separated from the car body and repaired. After the repai...

Problems solved by technology

In addition, because the support plate is installed on the support column, and the support frame is detachably connected to the support platform, and the support frame is connected to the support column by bolts, so that after the support frame is connected to the support column, its There is a distance between the upper and lower ends and the support table and support plate, which makes it difficult for the vibration on the lifting rail to be transmitted to the foundation through the support frame and support columns, and it is also difficult to achieve shock absorption

In addition, even if it can be transmitted to the foundation for shock absorption, but because the lifting rail is relatively long, the support frame is mainly installed at the two ends of the lifting rail, and there is no shock-absorbing measure for the middle part of the lifting rail, which also makes the middle of the lifting rail The vibration of the part is relatively large, such a large vibration may damage the lifting rail and other parts on the disassembly equipment
