Abstract

The invention discloses a digital readout gauging rule, and relates to the technical field of railway track measurement tools. The digital readout gauging rule comprises a rule body and a tilt angle sensor circuit board arranged in the rule body, the tilt angle sensor circuit board is connected with a circuit board base to form an integrated sensor adjusting plate, one end of the sensor adjustingplate is hinged to a circuit board positioning base arranged in the rule body through a cylindrical pin, the other end of the sensor adjusting plate is provided with a limiting part connected with thecircuit board positioning base, and the sensor adjusting plate and the circuit board positioning base are locked and positioned through an adjusting locking part; the sensor adjusting plate is provided with an eccentric shaft, the axial direction of the eccentric shaft is perpendicular to the axial direction of the cylindrical pin, an eccentric shaft head of the eccentric shaft is located in thesensor adjusting plate and connected with an operating part which extends out of the sensor adjusting plate, and a clamping retainer ring is clamped to the end, extending out of the sensor adjusting plate, of the tail of the eccentric shaft and fixed to the sensor adjusting plate. The digital readout gauging rule solves the problem that a sensor assembly in an existing digital readout gauging rulecannot adjust the vector direction.

Description

technical field [0001] The invention relates to the technical field of railway track measuring tools, in particular to a digital gauge gauge. Background technique [0002] The gauge ruler is a special measuring instrument used to measure the gauge between two strands of steel rails on a railway line. Its functions are divided into two parts: one is the horizontal length measurement, including the gauge, inspection distance and back protection distance. From the structural principle and From the point of view of traceability, these three parameters are interrelated and restrict each other. According to the current method of value transmission, the measurement error gradually increases from the track gauge to the inspection interval, and then to the back protection distance; the second is the vertical Height measurement, including level and superelevation, as the static geometric parameters of the line, has an essential difference in meaning. Level belongs to the category of s...
