Abstract

The invention relates to a method for non-contact measurement of the displacement of a tamping apparatus of a railway track lifting and lining tamping wagon. According to the method, the tamping apparatus, a CCD sensor and a signal output interface are included, the upper end of the tamping apparatus is provided with a tamping wagon crossbeam, the tamping wagon is fixed at the external part of thetamping wagon crossbeam, the upper end of the tamping wagon crossbeam is provided with a laser emitter and a CCD measuring apparatus, the internal part of the CCD measuring apparatus is provided withan optical lens, the CCD sensor is arranged above the optical lens, and the upper end of the CCD sensor displays an image. According to the method for non-contact measurement of the displacement of the tamping apparatus of the railway track lifting and lining tamping wagon, the image corresponds to the position of the tamping apparatus in the CCD sensor, laser spots can be reflected to the optical lens of the CCD measuring apparatus through the surface of the tamping apparatus and imaged on the CCD sensor, the laser spots are emitted to the CCD sensor through the optical lens of the CCD measuring apparatus to generate the image, and vertical displacement of the tamping apparatus relative to the tamping wagon crossbeam is accurately calculated through a relation between the displacement amount and the practical displacement.

Description

Technical field

[0001] The invention relates to the technical field of tamping vehicles, in particular to a non-contact method for measuring the displacement of a tamping device of a tamping vehicle for a railway pick-up track. Background technique

[0002] The tamping car is a type of large-scale road maintenance machinery (large machine for short), which is suitable for the construction of new lines of railway lines, the large and medium repair and screening operations of existing lines, and the maintenance operations of operating lines. It reciprocates up and down in the vertical direction. In order to ensure the quality of work, the rising and falling positions and positions of the tamping device need to be accurately controlled. For this reason, it is necessary to accurately measure the displacement of the tamping device in real time. The current methods for measuring this displacement are all contact The method is to install a sensor composed of a potentiometer, gear transm...
