Anti-derailing device for rail vehicle bogie and rail vehicle bogie

Abstract

The invention provides an anti-derailing device for a rail vehicle bogie. The anti-derailing device comprises at least one installing seat (1) installed at the bottom of the rail vehicle bogie (9). The installing seat (1) is provided with an anti-derailing sliding plate (2) stretching to ground rails (8). Transverse positioning and vertical-direction stretching length of the anti-derailing sliding plate (2) on the installing seat (1) simultaneously meet the following requirements that 1, the anti-derailing sliding plate (2) is located on the inner side of the ground rails (8) when a rail vehicle runs normally; 2, when at least one wheel set (6) of the rail vehicle climbs on the rails, the anti-derailing sliding plate (2) can act on the ground rails (8) to form transverse limiting junctures to limit the freedom degree of the rail vehicle, and then the rail vehicle is still restrained by the ground rails (8). According to the anti-derailing device, the rail vehicle bogie can be prevented from derailing during operation, especially derailing probably occurring after the wheel sets climb on the rails can be avoided, and therefore train safety and transporting efficiency are improved.

Description

technical field [0001] The invention belongs to the technical field of rail transit equipment, and in particular relates to a mechanical device capable of preventing derailment accidents of rail vehicle bogies during operation. Background technique [0002] Now, with the improvement of train speed and transportation efficiency, if a train derails, the line will be closed, the train will be canceled or delayed, so the requirements for the anti-derailment performance of the bogie are getting higher and higher, especially for the busy main line railway. [0003] The bogie without the anti-derailment device only relies on the rim of the wheel itself to prevent the bogie from derailing. Due to fewer restraint points, the anti-derailment ability is weaker. [0004] The Chinese patent document with the publication number CN204548142U discloses a rail vehicle and a derailment safety protection device. The basic principle of the device is to allow the separation of the wheel set and...

AI Technical Summary

Problems solved by technology

The bogie without the aforementioned anti-derailment device cannot effectively limit derailment accidents such as climbing rails. When the wheel set is separated from the track, the lateral vibration of the vehicle is relatively large
