Straddle type single-rail combined train bumper

Abstract

The invention relates to the field of safety protection of rail transportation, and in particular to a straddle type single-rail combined train bumper. The straddle type single-rail combined train bumper comprises a fixed train bumper and a slidable train bumper, wherein the fixed train bumper and the slidable train bumper are respectively arranged on a prefabricated line terminal PC (prestressed concrete) beam, and the slidable train bumper is arranged at the part with setting distance in front of the fixed train bumper; the slidable train bumper is in friction type sliding connection with the surface of the PC beam; the slidable train bumper is provided with a first impact part, a friction part and a first buffer structure; the fixed train bumper is provided with a fixed structure and a second buffer structure. The straddle type single-rail combined train bumper has the advantages that by adopting the structure, the fixed train bumper and the slidable train bumper are respectively arranged on the PC beam which is prefabricated as the line terminal, a train impacts the slidable train bumper, the slidable train bumper slides and rubs to consume the impact kinetic energy, the other impact kinetic energy is consumed by a hydraulic and pneumatic buffer of the slidable train bumper, and a large amount of the impact kinetic energy of the train is consumed; the backward moving slidable train bumper impacts the fixed train bumper, the remained impact kinetic energy is consumed by a hydraulic and pneumatic buffer of the fixed train bumper, and finally, the braking function is realized.

Description

technical field [0001] The invention relates to the field of rail traffic safety protection, in particular to a straddle-type monorail combined vehicle block. Background technique [0002] The car block is a safety protection device for urban rail transit. Its main function 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. In recent years, with the rapid development of urban rail transit, 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. Therefore, the issue of installing car stops at the end of the track of each line has received more attention. Contents of the invention [0003] The embodiment of the present invention provides a straddle-type monorail combination car block, which can solve the problem of ...
