Description

TECHNICAL FIELD

[0001] The utility model relates to rail transit technical field, concretely relates to a kind of suspension rail transit car stabilizer. BACKGROUND

[0002] Suspension rail train is called "Sky Train" for short, which belongs to monorail transit system. The track of Sky Train is above the train, supported by steel or concrete pillars in the air, suitable for rail transit between cities. Sky Train has the advantages of low construction cost, fast engineering construction, small land occupation, detachability, mobility, full-process automation, environmental protection, low noise and energy saving.

[0003] The stability of Sky Train vehicle is an important indicator of the operation of Sky Train. Since the vehicle is hung upside down under the track beam, when the vehicle stops at the platform, there is no other device to stabilize the vehicle, and the vehicle will sway when passengers get on and off the vehicle, causing a sense of insecurity and discomfort to passengers. At the same time, due to the sway, a large gap will be formed between the vehicle and the platform, which will cause a great safety hazard. Therefore, to ensure the safety and stability of the vehicle when entering and leaving the station, a car stabilizer is needed in the current Sky Train technical field.

[0004] The existing Sky Train stabilizer mostly uses traditional mechanical or hydraulic stabilizing mechanism, which has the problems of complex structure, difficult maintenance and high cost. At the same time, in terms of synchronous lifting control, the existing technology often cannot accurately control the movement of each lifting mechanism, resulting in instability when the train stops. Moreover, the overall size of the existing stabilizer is very large, occupying a large amount of space on the platform track side, which will also affect the construction of the platform area. Especially, the stabilizer stabilizing rod is in the air outside the platform, which needs high-altitude operation during installation and debugging, with the risk of falling. Moreover, the whole equipment is relatively heavy, making it inconvenient for debugging and measurement. UTILITY MODEL CONTENTS
