Problems solved by technology

However, in actual use, due to the influence of factors such as the wear and deformation of the measuring wheel, the wear of the servo motor drive roller, and the failure of the grating and encoder, the measurement of the length of the rail is deviated, exceeding the allowable deviation range, and the produced rail is unqualified. and difficult to detect

Abstract

The invention discloses a position-based steel rail length measurement system and a measurement method. The system comprises rail end detection devices mounted on fixed supports on the two sides or the single side of a steel rail conveying roller way, a signal transmission line and a data display device. The vertical distance between a measuring field of each rail end detection device and the saw face, close to the steel rail preparing sawing end, of sawing equipment is the same as the standard specified length of a steel rail. The rail end detection devices are connected with the data display device through the signal transmission line. The measurement method comprises the steps that the position value x of the end face of the sawn end of the steel rail is measured in real time through the rail end detection devices, x, the standard specified length value a and the standard parameter b are added through the data display device, and the steel rail length y is obtained; and when y is within the steel rail specified length deviation range, direct sawing is carried out, and otherwise, sawing is carried out after the position of the steel rail is adjusted in real time to be within the specified length deviation range. According to the position-based steel rail length measurement system and the measurement method, the steel rail length value can be calibrated, precision detection of the steel rail length is achieved, data are displayed in real time, and stability and reliability are achieved.

Description

technical field [0001] The invention relates to a measurement method of a position-based rail length measurement system, belonging to the technical field of rail length measurement. Background technique [0002] The allowable deviation of the rail length has clear requirements in the rail standards of various countries, and meeting the rail length deviation requirements of the corresponding standards is one of the important conditions for the qualification of a rail product. In the actual production process, the length of the rail is usually measured by a measuring wheel equipped with an encoder, a grating, and a servo motor, and the deviation generated during the measurement process is corrected through the corresponding program. When the measured length is consistent with the set sawing When the length is consistent, the rails are sawed to produce qualified length rails; sawing equipment including circular saw blades is used for sawing, and the sawing equipment is installe...
