Embodiment Construction
[0014] The specific implementation manner of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0015] Such as figure 1 As shown, a portable rail full-section profile geometric parameter detector suitable for use in rail transit. The tester is composed of an instrument base 1, clamping mechanisms 2 and 3, a fixed encoder 4, a main connecting rod 6, a moving encoder 5, a moving arm 7, a measuring arched arm 9, and a wheel 10. The boom 7 and the measuring bow arm 9 are connected by a rotatable joint 8, so as to ensure that the measuring bow arm 9 and the boom 7 can rotate 180° and remain relatively fixed, so that the wheels at the end of the measuring bow arm 9 can stick to the rail The shape can slide 360°.
[0016] When working, the instrument base is placed on the top of the rail and fixed by the clamping mechanisms 2 and 3. The fixed encoder 4 is installed in the instrument base 1, and its main shaft is connecte...

The present invention provides a portable rail traffic steel rail full cross-section silhouette geometrical parameter detector suitable for usage in rail traffic. The detector comprises an instrumentstand, a clamping mechanism, a fixed encoder, a main connection rod, a moving encoder, a moving arm, a measuring arc arm, a depended wheel and the like. The moving arm is connected with the arc arm through a revolving joint to ensure that the measuring arc arm and the moving arm perform 180-degree revolving and remain relatively stationary, allow the depended wheel at the end portion of the measuring arc arm to slide close to the profile of the steel rail and remain omnibearing contact with the profile of the full cross-section of the steel rail, and a control device (comprising a control circuit board and a software system) is employed to upload data collected and formed by two encoders to an upper computer through preprocessing of a solidification program to display the data at a management platform. The portable rail traffic steel rail full cross-section silhouette geometrical parameter detector can accurately measure geometrical parameters of all the curves (comprising a rail head,a rail jaw, a rail waist, rail feet and a rail bottom) of the steel rail full cross-section profile, is simple in operation and high in measurement precision, and is suitable for technical features of establishing a big data management platform at present.
Description
Technical field: [0001] The invention relates to the technical field of rail transit rail maintenance equipment, and is a portable rail full-section profile geometric parameter detector. Background technique: [0002] The detection of the geometric parameters of the full-section profile of the rail is still a model detection according to the current Chinese railway standards (see the former Ministry of Railways TB / T 3276-2011 "Rails for High-speed Railways" and TB / T 2344-2012 "43kg / m~75kg / m hot-rolled rail ordering technical conditions"), in recent years, foreign and domestic portable instruments and mechanical rail head measuring instruments have also been developed by laser methods, but they are limited to the measurement of the rail head (mainly used to measure the rail head Wear and profile repair), cannot track the state of the technical geometric parameters of the entire rail. The sample test is not only susceptible to human operation, sample wear and other factors t...
