AI Technical Summary

Technical Problem

Existing magnetoelectric sensors at railway crossings are easily triggered by interference from metal objects, have strict installation requirements and are easily damaged. They are also easily affected by weather and wear, leading to misjudgment and failure.

Method used

A railway rail pressure sensor fixture device is designed, including fixtures and prestressed pressure adjustment components arranged at intervals along the rail. The pressure sensor is fixed by a fixing screw and a protective cover to avoid damage, and the prestressed pressure adjustment component ensures accurate measurement.

Benefits of technology

The pressure sensor is firmly installed to avoid false triggering and damage, is easy to install, adapts to different rail bottom surfaces, measures accurately, reduces climate impact, and extends service life.

Abstract

The utility model discloses a railway steel rail pressure sensor clamp device which comprises two sets of clamps which are arranged along a steel rail in a front-back spaced mode, each set of clamp comprises two clamp bodies which are clamped on the two sides of the bottom of the steel rail respectively, a fixing screw is arranged between the two clamp bodies in a penetrating mode, and the fixing screw is matched with a first nut to lock the two clamp bodies. Sensor installation parts are installed in the middles of the two fixing screw rods, a pressure sensor is connected between the two sensor installation parts, the pressure sensor is located in the center of the lower portion of the steel rail, and a prestress adjusting assembly is arranged between the middle of the pressure sensor and the bottom face of the steel rail. The device is simple in overall structure and convenient to install, the prestress adjusting assembly is arranged between the pressure sensor and the bottom of the steel rail, different rail bottom faces can be conveniently dealt with, initial stress values are set, the stress values of the pressure sensor can be changed by tiny deformation generated by the steel rail when a train passes, and the stress value change can be used for judging whether the train passes above or not.
