Passive type ring spring car stop

Abstract

The invention relates to the technical field of rail transit train or train line end safety protection, in particular to a sliding car stop. The device comprises a collision head, an elastic compression device, a main body frame, a connecting rod structure, a sliding way and a friction device. The main body frame is of a metal frame structure and comprises an upper cylindrical structure and a lower trapezoidal frame structure. The elastic compression device is arranged in the cylindrical structure. The collision head is installed from the front portion of the cylindrical structure of the mainbody frame, and the elastic compression device is encapsulated in the main body frame. The sliding way is installed at the bottom of the trapezoidal frame structure of the main body frame, the top ofthe connecting rod structure is hinged to the elastic compression device, the middle of the lower part of the connecting rod structure is arranged on the sliding way and can slide along the sliding way, and the two sides of the lower part of the connecting rod structure are each provided with a friction device. The friction devices are hinged to the connecting rod structure, the sides of the friction devices are in contact with the side faces of a steel rail, and the friction devices rub with each other to work. According to the technical scheme, the problems of limited energy absorption, limited arrangement quantity, no continuity, high production and maintenance cost and the like in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of safety protection at the end of rail transit trains or train lines, in particular to a sliding type stopper. Background technique [0002] With the improvement of the protection level of train safety operation, the requirements for the safety protection ability of the stopper are getting higher and higher. The existing car stop has the following defects due to its own structure and the length limitation of the railway line: [0003] (1) Due to the limitation of the length of the line safety line, the number of dampers at the rear end of the sliding car stop is restricted, and the energy absorbed is limited; [0004] (2) Multiple dampers absorb energy step by step, without continuity; [0005] (3) The damping force of the damper is determined by the clamping rail pressure of the damper, and has nothing to do with the impact force of the train; [0006] (4) The impact kinetic energy of the train exceeds ...

AI Technical Summary

Problems solved by technology

[0003] (1) Due to the limitation of the length of the line safety line, the number of dampers at the rear end of the sliding car stop is restricted, and the energy absorbed is limited;

[0004] (2) Multiple dampers absorb energy step by step, without continuity;

[0006] (4) The impact kinetic energy of the train exceeds the safety protection requirements, and the number of existing layout equipment and damper layout is difficult to achieve;

[0007] (5) The existing sliding type car stop equipment adopts hydraulic contact to improve the buffer capacity, but the production and maintenance costs are relatively high
