Embodiment Construction

[0010] A device for detecting railway wear and tear, wherein the infrared position sensing mechanism, the photosensitive position sensing mechanism and the power mechanism are respectively connected with a data acquisition and processing unit. Under the auxiliary support of the support rod, the data acquisition and processing unit controls the power mechanism to drive the infrared position sensing mechanism to move at a constant speed on the guide rail mechanism installed with the photosensitive position sensing mechanism. The infrared position sensing mechanism and the photosensitive position sensing mechanism respectively measure the cross-sectional size and lateral movement of the rail in real time. The reflective monitoring mechanism cooperates with the infrared position sensing mechanism to complete the measurement of the track size. Finally, the said data acquisition and processing unit accurately calculates and stores the amount of railway rail wear through data analysi...

Abstract

The invention relates to a railway steel rail measuring device, in particular to a device used for detecting railway abrasion. Under auxiliary supporting of supporting rods (1), a data collecting andprocessing unit (2) controls a power mechanism (5) to drive an infrared position sensing mechanism (6) to move at a uniform speed on a guide rail mechanism (4) provided with a photosensitive positionsensing mechanism (3). The infrared position sensing mechanism (6) and the photosensitive position sensing mechanism (3) are used for measuring the steel rail sectional size and transverse moving amount in real time correspondingly. A light-reflection monitoring mechanism (7) is matched with the infrared position sensing mechanism (6) to measure the rail size. Through data analyzing and processing, the data collecting and processing unit (2) precisely calculates and stores the railway steel rail abrasion amount. By means of measuring the rail size, effective positioning of the measuring basisis realized, precise calculation of the steel rail abrasion value is completed, and measuring precision of railway steel rail abrasion is greatly improved.

Description

technical field [0001] The invention relates to a railway rail measuring device, in particular to a device for detecting railway wear. Background technique [0002] With the continuous improvement of railway operation speed and density, the impact load of wheel and rail will also increase, which will inevitably lead to increasingly serious wear of railway rails, directly affecting the safety of train operation, passenger comfort and service life of rails. [0003] Develop high-precision intelligent detection equipment to guide the grinding and maintenance of rail sections, formulate scientific and reasonable rail wear repair strategies, re-modify the rail profile in the turnout area, and restore the design status of the rail in the turnout area, which is conducive to improving the running stability and comfort of the train. It has obvious comprehensive benefits such as delaying the occurrence cycle of rail defects and prolonging the service life of rails. [0004] At presen...
