Embodiment Construction

[0037] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments:

[0038] Such as figure 1 An anti-derailment bogie based on side frame positioning detection is shown, including axle box positioning device 1, side frame composition 2, bolster composition 3, basic braking device 4, and axle composition 5;

[0039] Such as figure 2 As shown, it also includes a derailment detection device 6 installed at the end of the side frame assembly 2. The derailment detection device 6 includes two pairs of support seats 7, two beams 8 and two pairs of laser displacement meters and processor systems 9;

[0040] Such as image 3 As shown, the side frame composition 2 includes two side frames 2a arranged in parallel. The two ends of the side frame 2a are integrally molded with a mounting base 2b, and the mounting base 2b is provided with four openings. Holes 2d, and the through holes 2d are distributed in a matrix, and a process square...

Abstract

Provided are a derailing prevention bogie based on side frame positioning detection and a derailing detection method therefor. The derailing prevention bogie comprises a shaft box positioning device (1), a side frame assembly (2), a swing bolster assembly (3), a fundamental braking device (4), a wheel shaft assembly (5), and a derailing detection device (6) mounted at an end part of the side frame assembly (2). The derailing detection device (6) comprises two pairs of supporting bases (7), two transverse beams (8) and two pairs of laser displacement measurers and processor systems (9). Through additionally providing the derailing detection device on the bogie, an early warning function before a railway vehicle is derailed is realized and the problem that the railway vehicle cannot predicate derailing is solved. Guarantees are provided for railway transportation safety and reduction of freight derailing accidents.

Description

Technical field [0001] The invention relates to the technical field of railway transportation equipment, in particular to a derailment prevention bogie based on side frame positioning detection and a derailment detection method thereof. Background technique [0002] Train derailment is a major traffic accident in the operation of railway vehicles. The occurrence of derailment accidents will cause damage to vehicles, goods, transportation equipment and communication equipment, and in serious cases will also harm lives, so it is highly valued by countries all over the world. Since the speeding up of my country's railways in 1997, the derailment of freight trains has been on the rise; in the past 10 years, the rate of derailment accidents in major and major railway accidents in my country has reached about 70%. In order to ensure the safety of railway transportation, it is an important and urgent task to find out countermeasures to reduce the derailment of freight cars. [0003] The...
