Abstract
The invention discloses a steel rail rail-head type stress sensor used for railway vehicle overload and unbalanced load detection. The sensor comprises two rectangular substrates and two steel rail fixtures, wherein a vertical inner side surface and a vertical outer side surface opposite to each substrate are independently provided with two blind holes; in addition, the blind holes on two side surfaces are coaxially oppositely arranged one by one; a resistance strain gage is independently arranged in each blind hole; a position where two coaxial blind holes of the substrate are positioned is of a shear beam structure; and two end parts of two substrates are fixedly connected through corresponding steel rail fixtures, and during installation, a supporting bolt is independently in supportingconnection between the top ends of the two substrates and the jaw of the steel rail rail head. When a wheel passes through a steel rail zone where the steel rail stress sensor is positioned, the wheel acts on the steel rail rail head, and the steel rail rail head is stressed to generate deformation. The steel rail rail-head type stress sensor collects the change amount of the steel rail stress, then, the stress situation of wheels on the steel rails on two sides is analyzed to obtain a result for showing whether the vehicle is subjected to overloading or unbalance loading or not, detection accuracy is high, and a detection result is accurate.
Description
technical field [0001] The invention relates to the field of pressure detection, in particular to a rail head type stress sensor used for the 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 head type stress sensor for the detection of over load and unbalanced load of railway vehicles. The purpose of overload detection. [0004] Technical scheme of the present invent...
