Abstract

A rail vehicle bogie derailment prevention device of the present invention comprises at least one mounting seat (1) mounted on the bottom of the rail vehicle bogie (9), and a mounting seat (1) is provided with a rail extending toward the ground track (8). The anti-derail slide plate (2); the lateral positioning of the anti-derail slide plate (2) on the mounting seat (1) and the extension length in the vertical direction simultaneously meet the following requirements, namely: 1) The anti-derail slide plate (2) is placed on the rail vehicle It is located on the inner side of the ground rail (8) during normal driving; 2) when at least one wheelset (6) of the rail vehicle climbs the rail, the anti-derailment slide plate (2) will act with the ground rail (8) to form a lateral limit node to The degree of freedom of the rail vehicle is restricted so that it remains constrained by the ground rail (8). The derailment prevention device of the present invention can prevent the derailment of the rail vehicle bogie during operation, especially the derailment that may occur after the wheelset climbs the track, thereby improving train safety and transportation efficiency.

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...
