The working principle of the embodiment is as follows: when the train is braked to lose efficacy and collides an emergency stop trolley, the train firstly contacts the energy absorption device, the train applies thrust (kinetic energy) to the energy absorption device, the energy absorption device collapses at the moment, and the kinetic energy is consumed by the elastic potential energy of the energy absorption box to a small part (equivalent to absorbing the kinetic energy of the small part of the train); when the kinetic energy of the train overcomes the elastic potential energy of the energy absorption box, the train transmits the kinetic energy to the trolley frame body, the counterweight device, the wheel braking device and the derailment prevention device through the energy absorption device, after the kinetic energy overcomes the gravitational potential energy formed by the trolley frame body, the counterweight device, the wheel braking device and the derailment prevention device, the train forces the emergency forced stopping trolley to move towards the advancing direction of the train, because the counterweight device is far away from the train, the driving kinetic energy borne by the counterweight device is relatively small at the moment, the kinetic energy received by the energy absorption device, the trolley frame body, the wheel braking device and the derailment prevention device which are close to the train is relatively large, and because the derailment prevention device is locked with the track, under the condition that the emergency forced stopping trolley cannot advance along the horizontal direction, the emergency forced stopping trolley releases deformation along the Z-axis direction, the thrust in the X-axis direction provided by the train rotates to the Z-direction pressure along the, at this time, the counterweight device bears the gravity and the pressure at the same time, the friction force between the slide rail of the counterweight device and the track is increased, the kinetic energy applied by the train is converted into the internal energy of the emergency stop trolley, the internal energy and the kinetic energy of the train are mutually offset, and as shown in fig. 6, the speed of the train with brake failure is gradually reduced, so that the emergency stop effect is realized.
The specific application method is listed, taking urban rail transit as an example, a train is formed by 6 groups, each carriage is calculated according to the weight of 30t, the mass of an emergency forced stopping trolley for a train rail is 8-15 t, the condition that the train impacts the emergency forced stopping trolley at the initial speed of 50Km/h is defined, the analysis result is shown in a train deceleration curve shown in fig. 7, the emergency forced stopping trolley can provide the deceleration of about 1.5g, as shown in fig. 8, the train speed is gradually and smoothly reduced according to the speed curve, and the effective braking distance can be controlled to be about 18-25 m.
According to the scheme of the invention, the emergency danger avoiding track is arranged at the train subsection station or the terminal area and is connected with the main track, the emergency forced stopping trolley is arranged on the emergency danger avoiding track and is away from the main track by a distance, and when the train is in brake failure or other accidents, a driver is in contact with the dispatching center to guide the train to move into the emergency danger avoiding track nearby for forced stopping.
