A continuous detection device for track surface wear

Abstract

The invention relates to the technical field of track detection equipment, and discloses a continuity detection device for track surface wear, including a rail, the top of the rail is clamped with a fixed bracket, and the bottom of the left side of the fixed bracket is fixedly installed with a side Pulley, the top of the inner cavity of the fixed bracket is movably socketed with a top pulley through the installation bracket, and the middle part of the front of the fixed bracket is provided with a detection mechanism. The track surface wear continuity detection device, through the setting of the probe mechanism and the piezoelectric sheet, utilizes the subtle movement generated by the probe mechanism when it moves on the rail and converts it into a current signal for feedback, which is different from the existing track wear Compared with the measuring ruler, it can carry out continuous detection on the specified track and obtain continuous detection data instead of point-to-point detection, resulting in high stability and reliability of the obtained detection data, which is convenient for effective sorting and analysis , thereby effectively improving the detection accuracy of the device.

Description

technical field [0001] The invention relates to the technical field of rail detection equipment, in particular to a continuity detection device for rail surface wear. Background technique [0002] Because most of the rails in rail transit are distributed outdoors, and the outdoor living environment is complex, they are often washed and corroded by rain, exposed to the sun, and also need to bear the pressure of the train carriage and the severe friction of the wheels, resulting in the rails Wear and tear has become an inevitable phenomenon. Therefore, in order to ensure the normal and safe operation of operating vehicles, it is necessary to regularly detect the surface wear of the rails, replace the rails with major safety hazards, and obtain the wear data of the rails. Analyze severely worn areas to replace rails of different material types, or optimize the travel route of the rails to slow down the wear of the rails. [0003] However, the existing track surface wear detect...

Problems solved by technology

[0005] The invention provides a continuity detection device for track surface wear, which has the advantages of good continuity of detected data, high stability, low error and high detection accuracy, and solves the problem of existing track surface wear detection. Setting, only the measurement points can be selected in a certain area for detection, and the continuous detection of a section of rail cannot be carried out, resulting in large dispersion and large errors in the detection data, which seriously affects the accuracy of the detection of the surface wear of this section of rail. At the same time, it is impossible to make an accurate analysis and judgment on the cause of the wear of this section of rail
