Applied to crh EMU parking fixed hydraulic buffer car stopper

Abstract

The invention relates to a fixed type hydraulic buffering car stopper applied to parking of a CRH motor train unit. The car stopper comprises an anti-collision mechanism, a buffering mechanism, a supporting mechanism and a connection mechanism. The anti-collision mechanism is provided with a buffering base plate, an anti-collision frame and a rectangular guide frame, and the anti-collision frame and the rectangular guide frame are respectively formed by welding steel plates; the supporting mechanism is of a box shape and is formed by welding multiple steel plates; the buffering mechanism is fixed into the supporting mechanism and comprises a self-reset type hydraulic buffer which is horizontally arranged and located in the rectangular guide frame; the connection mechanism is composed of a plane steel plate provided with multiple high-strength bolts, and the lower end of the supporting mechanism is connected with the high-strength bolts on the plane steel plate and is fixed into concrete. By means of the structure, the fixed type hydraulic buffering car stopper applied to parking of the CRH motor train unit has the advantages of being safe, reliable, good in buffering effect, compact in structure, reasonable in installation mode, good in attractiveness and the like.

Description

technical field [0001] The invention relates to a fixed hydraulic buffer car stopper applied to the parking of CRH EMUs, and relates to the field of car stoppers. Background technique [0002] The mass and inertia of rail transit vehicles are large, and the friction between the wheels and rails is small. Therefore, it is a very necessary passive safety measure to install protective equipment such as car stops at the end of the line. The main function of the stopper is to prevent the train from rushing out of the line when it accidentally loses control, prevent personnel injury and damage to vehicles and other facilities, and ensure operational safety. [0003] In recent years, with the rise and development of high-speed railways, the number of operating lines has gradually increased, and accidents of trains running out of the end of the line due to accidental loss of control have occurred from time to time. The setting of stoppers and related issues are getting more attentio...

AI Technical Summary

Problems solved by technology

Its disadvantage is that the length of the equipment itself is obviously lengthened, that is, it occupies more length of the line, and there are disadvantages such as lifting up the out-of-control vehicle before stopping, loosening track spikes, unreasonable force on the main structure of the car stopper, etc.
