The invention belongs to the field of rail transit process equipment, and particularly relates to derailing and rerailing equipment and a rescuing method suitable for a 100% low-floor tramcar.
Background
Compared with a subway train with completely independent right of way, derailment can be caused by external collision, overspeed, undersized turning radius or wheel set failure in the normal running process of a 100% low-floor tramcar. Research results show that when the tramcar is laterally impacted by the car at the speed of 20km/h at a level crossing, the maximum derailment coefficient of the tramcar reaches 1.63, and the tramcar has a larger derailment risk; in addition, when the automobile impacts the front end head and the rear end head of the tramcar, the transverse impact force born by the impacted vehicle can be transmitted to other vehicles only through the workshop hinge structure on one side, so that the possibility of derailing of the tramcar is high; meanwhile, if the friction coefficient of the wheel rail is reduced due to weather factors such as rain, snow and the like, the braking capacity of the steel rail on the movement of the wheel is weakened, the overspeed passing curve can be caused, and the derailment risk of the tramcar is increased. And after the tramcar has a derailment accident, the re-rail operation is required to be quickly carried out, and the line operation is recovered. However, the existing derailment and rerailing equipment is complete equipment for subways, and currently adopted rerailing equipment and a method are as follows:
firstly, placing a three-stage oil cylinder at the bottom of a train, and jacking a derailed train to be 10-20 cm above a rail surface through the oil cylinder; then, the derailed train is translated to the upper part of the rail surface through the cooperation of equipment such as a transverse moving oil cylinder, a transverse moving trolley and the like to complete the rerailing operation.
Because the wheel diameter of the 100% low-floor tramcar is smaller, the floor surface height is lower, the clearance height from the car erecting point under the floor to the rail surface is only about 180mm to 200mm, while the height of the traverser beam of the existing rerailing equipment is 140mm, the height of the traverser is 110mm, the stacking height of the two components is 250mm, which is far more than the height of 180mm to 200mm at the bottom of the 100% low-floor tramcar, and the oil cylinder has no space for installation. Thereby leading to the fact that the existing equipment cannot be used for 100% low-floor tram rerailing operation.
