Novel shock resisting device and working method thereof

Abstract

The invention relates to a novel shock resisting device and a working method thereof. The novel shock resisting device comprises a first joint, an upper outer barrel, a lower outer barrel and a secondconnecting head connected successively. The top of the lower outer shell is sleeved into the upper outer barrel and is movably connected to the upper outer barrel; an aluminum honeycomb and a magnetorheological shock absorber outer barrel are arranged in the lower outer barrel, the aluminum honeycomb is arranged at the bottom of a lower end cover, a piston rod is arranged in the magnetorheological shock absorber outer barrel, the top end of the piston rod stretches out of the upper end cover and is connected to a collision head, and a reset spring is mounted between the collision head and theupper end cover in a sleeved manner; an electromagnetic coil winds the piston rod, the lower part of the piston rod is a damping piston and a damping hole is formed in the damping piston, a guide plate is arranged at the bottom end of the damping piston, and the lower side of the guide plate is filled with a magnetorheological fluid. The novel shock resisting device is mounted between two compartments of a mine car. When the speed of the rear mine car is greater than the speed of the front mine car or when the front mine car is braked, shock of the rear mine car is prevented to buffer, so that deceleration is performed effectively. When an accident happens, follow-up compartments are buffered to prevent secondary injury of the accident effectively.

Description

technical field [0001] The invention relates to a novel anti-shock device and its working method, in particular to an anti-shock buffer device used between two compartments of a mine car, and belongs to the technical field of buffer devices. Background technique [0002] Mining cars are the main means of transportation in the production of inclined shafts in mines. Because the exit of the inclined shaft has a certain slope, due to abnormal reasons, the mining cars often slip back into the shaft or cause collisions between the carriages. In order to prevent accidents, now In the production operation, each wellhead is required to implement the protective measures of "one slope and three gears", which can prevent accidents to a certain extent. [0003] When the mine car is running on the roadway, it usually connects multiple carriages front and rear for operation. When the speed of the rear car is greater than the speed of the front car or the front car brakes, in order to prev...

AI Technical Summary

Problems solved by technology

[0006] After retrieval, most of the buffers used on mine cars are brake buffers of a single car at present, which are used for braking or damage prevention buffering. No anti-collision buffer device used between cars has been found. Therefore, it is necessary to provide a The anti-shock buffer device between the carriages of the mine car can ensure the stable operation between the carriages and avoid the collision damage between the carriages
