Problems solved by technology

When the train is overloaded or unbalanced, it is very easy to cause traffic accidents, resulting in loss of life and property
However, the detection of overload, eccentric load and total weight of vehicles on the railway still adopts the method of parking detection, which is cumbersome and relatively backward

Abstract

The invention discloses a steel rail stress sensor for the overload and unbalanced load detection of a railway vehicle. The sensor is characterized in that the sensor comprises a rectangular base bodyand two steel rail clamps connected above the base body, the opposite front and back end faces of the base body are provided with two blind holes, the blind holes on two end faces are arranged oppositely and coaxially one by one, resistance strain gauges are arranged in the blind holes, and a part where two coaxial blind holes are located is a shear beam structure. By installing the base body with the structure of two shear beams on a steel rail, the stress detection of the steel rail is achieved, when a vehicle wheel passes a steel rail section where the steel rail stress sensor is located,the vehicle wheel acts on the steel rail, the steel rail is deformed under stress, the steel rail stress sensor collects the change amount of the stress of the steel rail, then the stress of wheels ontwo steel rails is analyzed, whether the vehicle is in an overload or unbalanced load can be determined, the detection precision is high, and the detection result is accurate.

Description

technical field [0001] The invention relates to the field of pressure detection, in particular to a rail stress sensor used for detection of excessive and unbalanced loads of railway vehicles. Background technique [0002] Railways are mostly used for long-distance transportation, and they have developed rapidly because of their high speed and low price. When the train is overloaded or unbalanced, it is very easy to cause traffic accidents and cause loss of life and property. However, the detection of overload, eccentric load and total weight of vehicles on the railway still adopts the way of parking detection at present, which is troublesome and relatively backward. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a rail stress sensor for the detection of over-balanced loading of railway vehicles. purpose of testing. [0004] Technical scheme of the present invention is: [0005] A rail stress sensor for rail...
