Anti-creep power-absorption structure device of train

Abstract

The invention discloses an anti-creep power-absorption structure device of a train. The device comprises anti-creep teeth, an internal power-absorption plate, a guide device, an external power-absorption cover plate and a back seat plate, wherein an antiskid groove is arranged at the external side of the anti-creep teeth; the guide device is connected between the anti-creep teeth and the back seat plate; the external power-absorption cover plate is welded on the guide device between the anti-creep teeth and the back seat plate; and the internal power-absorption plate is discontinuously welded at the internal side of the external power-absorption cover plate. In the invention, the internal power-absorption plate and the external power-absorption cover plate are taken as the core components, which are welded together by a special discontinuously welding manner; meanwhile, an especial bent part is arranged at the front end of the internal power-absorption plate to reduce the buckling deformation force, guide the power absorption and remove the buckling deformation; the guide device can prevent the power-absorption plate from accidently buckling and deforming; and the anti-creep teeth are arranged at the front end to effectively prevent the train from creeping during the collision.

Description

technical field [0001] The invention relates to an anti-climbing energy-absorbing device structure, which belongs to the fields of mechanical design and collision protection. Background technique [0002] With the continuous progress and development of rail transit technology, the issue of collision safety, as an important part of modern vehicle design, has become a hot spot in the design and research of rail vehicles; Or the friction, fracture, buckling, creasing and other damage forms of the weak part of the head car body will dissipate the huge impact kinetic energy, so as to protect the life safety of the occupants and the integrity of the main structure of the rail vehicle to the greatest extent. And anti-climbing energy-absorbing device is required, which is convenient for installation, disassembly and replacement. At present, anti-climber structures made of steel are commonly used on trains, and the anti-climber structures made of steel have disadvantages such as lar...
