Abstract

The invention discloses a derailment prevention bogie based on bearing saddle positioning detection and a derailment detection method. The derailment prevention bogie comprises axle box positioning devices, side frame components, swing bolster components, foundation brake gears and wheel axle components, wherein a bearing saddle is installed between each side frame component and each axle box positioning device; and the derailment prevention bogie also comprises derailment detection devices installed on the inner side surfaces of four bearing saddles. In addition, the invention also provides the derailment detection method. According to the invention, by additionally arranging the derailment detection devices on the bogie, an early-warning function before derailment of railway vehicles is realized, the problem that the derailment of the railway vehicles cannot be predicted is solved, and guarantee is provided for ensuring railway transportation safety and reducing freight vehicle derailment accidents.

Description

technical field [0001] The invention relates to the technical field of railway transportation equipment, in particular to an anti-derailment bogie and a derailment detection method based on bearing saddle positioning detection. 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 even life in serious cases, so it is highly valued by countries all over the world. Since my country's railway speed was increased in 1997, the derailment of freight trains has been on the rise; in the past 10 years, the rate of derailment accidents in my country's major railway accidents is as high as about 70%. In order to ensure the safety of railway transportation, it is an important and urgent task to find out the countermeasures and reduce the derailment accidents of freight cars. [0003] The causes...
