Abstract

The invention provides a steel railhead profile measuring instrument. The steel railhead profile measuring instrument comprises a measuring support arm, an encoder connecting rod, a first encoder, a second encoder, a fixed seat, a USB interface and a telescopic support rod, wherein the measuring support arm is herringbone, and detection wheels are arranged at two ends in the horizontal direction of the herringbone measuring support arm; the top end of the herringbone measuring support arm is connected with the first encoder, the first encoder is connected with the second encoder through the encoder connecting rod, the second encoder is fixed on the fixed seat; the telescopic support rod is connected with the fixed seat through a telescopic support rod seat, and a datum bottom plate is connected below the telescopic support rod seat. The steel railhead profile measuring instrument can be used for rapidly and conveniently scanning profiles of the left side and the right side of a steel railhead, more importantly, the steel railhead profile measuring instrument can be used for measuring a profile curve, which cannot be measured in the prior art, of a lower jaw part of the steel railhead, thereby having quite high measuring efficiency and accuracy and being simple in structure and convenient to use.

Description

technical field [0001] The invention relates to the technical field of measuring equipment, in particular to a rail head profile measuring instrument. Background technique [0002] Whether the outline dimensions, straightness and twist of the rail meet the standards will affect the safety, stability and speed of the railway operation, so it is necessary to detect the outline dimension of the rail in time to ensure the normal operation of the train. In the prior art, the profile measurement tools of rail head section mainly include contact type and non-contact type, and the contact type measurement tools are mainly vernier calipers, depth gauges and some special rail templates. These measurement tools are simple in structure but cumbersome to operate, poor in measurement accuracy, and even need to go through a series of calculations to know, the detection cost is high and the efficiency is low. In addition, none of these prior art techniques can measure the profile of the lo...
