Active supporting device for preventing rollover of rail transit vehicle caused by derailing

Abstract

The invention provides an active supporting device for preventing rollover of a rail transit vehicle caused by derailing. The device comprises a cylinder body and a supporting column, wherein the cylinder body is provided with a piston cavity; the inner wall of the upper end of the cylinder body is provided with an upper clamping groove; the inner wall of the lower end of the cylinder body is provided with a lower clamping groove; the supporting column is movably arranged in the cylinder body; the upper end of the supporting column is provided with a piston plate; the piston plate is in sealed contact with the inner wall of the cylinder body; the side wall of the piston plate is telescopically connected with an elastic block; the elastic block is clamped in the upper clamping groove or the lower clamping groove. According to the active supporting device for preventing rollover of the rail transit vehicle caused by derailing, the vehicle can be supported by extending the supporting column of the vehicle out under the condition that the vehicle has the rollover trend, the vehicle rollover accident is avoided, and the safety of the vehicle is effectively protected.

Description

technical field [0001] The invention relates to an active support device for preventing rollover of a rail transit vehicle caused by derailment. Background technique [0002] At present, various types of high-speed EMUs, locomotives and passenger cars do not have devices to prevent train rollover. With the vigorous development of my country's railway industry, the speed of passenger and freight trains has been greatly improved, which puts forward higher requirements for the safety of trains. If the train runs on the line, it will derail if it encounters an abnormal condition of the wheel and rail. In severe cases, it will cause the vehicle to roll over. In addition, if two trains collide with each other, it will also cause the vehicle to derail and roll over. The rollover of the vehicle will cause great personal injury to the people on the vehicle, and bring about extremely serious consequences such as damage to goods and scrapping of the train. For example, in the 7.23 ac...

AI Technical Summary

Problems solved by technology

When the train is running on the line, if it encounters an abnormal condition of the wheel and rail, it will derail. In severe cases, it will cause the vehicle to roll over. In addition, if two trains collide with each other, it will also cause the vehicle to derail and roll over.

The rollover of the vehicle will cause great personal injury to the people on the vehicle, and bring about extremely serious consequences such as damage to goods and scrapping of the train.

For example, in the 7.23 accident, due to the rear-end collision of the train, the No. 1, No. 2 and No. 3 carriages of the D301 train rolled over and fell from the viaduct, causing a large number of casualties and major property losses.
