Air buffer type train impact energy dissipation device

Abstract

The invention relates to an air buffer type train impact energy dissipation device, which is arranged at the front end of a train carriage. The device comprises a headstock cover which is arranged atthe front end of a train, is internally provided with an anti-collision support structure and is used for absorbing impact energy during impact, a safety air column structure which is used for absorbing and converting impact energy and comprises a plurality of hollow air columns with openings at the front ends, supporting columns with rear ends inserted in the air columns from the front openings of the air columns and air generation units arranged at the rear ends of the air columns and used for generating buffer air in rear end space. The rear ends of the air columns are fixed to the front end of the train carriage, and the front ends of the supporting columns are fixed to the headstock cover. Compared with the prior art, the device has the advantages of being small in occupied space, good in energy absorption effect, low in cost, high in reliability and the like.

Description

technical field [0001] The invention relates to the field of train safety operation, in particular to a gas buffer type train impact energy dissipation device. Background technique [0002] Safety issues during train operation have always been the focus of prevention. Every rear-end collision of a train will attract widespread attention from the society, and the social impact will also fluctuate accordingly. Not only will there be loss of life and property, but it will also be detrimental to social stability. For the research on the collision of mechanical equipment, the material of the equipment itself is the main way to absorb the impact energy when it deforms, and the rest of the impact energy will be dispersed to other places for conversion and consumption. Therefore, every train rear-end collision accident will become the focus of the international media. The closer the train compartment is to the front position, the greater the deformation of the car body and the more ...

Problems solved by technology

[0002] Safety issues during train operation have always been the focus of prevention. Every time a train rear-end collision occurs, it will be widely concerned by the society, and the social impact will also fluctuate. Not only will there be loss of life and property, but it will also be detrimental to social stability.

But at present, by changing the supporting structure of its internal space, it is limited by the internal space of the train vehicle. The second choice of changing the material is limited by the absolute limitation that the new material can subvert the physical properties of the old material, relying solely on the new physical properties of the material. This approach is not operational for today's problem solving

Most of the current technology is still in the fixed internal space of the vehicle, looking for the balance point of materials and internal structure. Due to the long-term accumulation of this method, the structure has been basically determined, and there is not much room for improvement and optimization.
