Deviation prevention energy absorption locking device

Abstract

The invention provides a deviation prevention energy absorption locking device and relates to the technical field of passive safety of rail vehicles. The top end of a rotator of a male locking structure is fixedly connected with the outer side of the bottom of a square box; energy absorption pipes are fixed to the inner side of the bottom of the square box; one ends of guiding rods are fixed to the inner side of the bottom of the square box; four through holes with the spaces being equal to those of the guiding rods are uniformly formed in a square plate connected with a cover plate through breaking bolts; the cover plate is fixedly connected with the opening end of the square box; the four protruding ends of a combined sliding plate in a shape like the Chinese character 'jing' are stored in sliding grooves of the side face of the square box and make contact with the inner wall of the square box through second reset springs; one end of a connecting rod is fixed to the square plate, and the other end of the connecting rod is fixedly connected with the flat end of a conical head; square groves and annular grooves are formed in the conical head; the top end of a rotator of a female locking structure is fixedly connected with the outer side of the bottom of a variable-diameter cylinder; a trapezoidal plate is fixed to the inner wall of the variable-diameter cylinder; and an arc-shaped sliding plate is stored in a sliding groove of the variable-diameter cylinder and connected with the inner wall of the variable-diameter cylinder through first reset springs.

Description

technical field [0001] The invention relates to the technical field of rail vehicle passive safety. Background technique [0002] In order to be able to absorb the impact energy of the collision, so as to protect the life safety of the occupants and the integrity of the main structure of the vehicle to the greatest extent, energy-absorbing devices of different capacities are often placed at the end of the car body according to the needs of train collision energy management to absorb energy in a controllable manner. Kinetic energy and energy-absorbing devices have become an important part of the train passive safety technology field. [0003] At present, the energy-absorbing device is basically applied on both sides of one side of the front car of the train, and is combined with the anti-climbing device to form an anti-climbing energy-absorbing device, which can not only absorb the collision energy, but also limit the climbing behavior of the active car and the passive car fr...
