Abstract
Disclosed is a railcar wheel diameter measuring device which is used to detect and monitor the diameter of the wheels of railway vehicles, subway trains and light railway trains on line. The railcar wheel diameter measuring device is characterized in that the device consists of a locating bracket, two special locating pins, a magnetic iron mechanism and a crawling measuring head. The two locating pins and the magnetic iron mechanism are reliably positioned with the wheel and the measuring head can precisely measure the height of the flange of the wheel through two coders and two swiveling jibs; then the diameter of the running wheel can be worked out through geometrical calculation. Adopting a reliable mechanical locating structure, the railcar wheel diameter measuring device is convenient and reliable to operate and can quickly measure the diameter of the wheel precisely; the railcar wheel diameter measuring device can be conveniently connected with a control computer through a USB interface. Meanwhile the railcar wheel diameter measuring device introduces a double-color LED light to indicate the operation process.
Description
Technical field
The utility model relates to railway wheel, and particularly a kind of railway wheel diameter measuring device, measurement mechanism are used for the accurate measurement of railway wheel, city underground wheel, light rail wheel diameter.
Background technology
The diameter of railway wheel is the key parameter that has influence on the bullet train traction control.The device that needs an online accurate inspection vehicle wheel diameter of energy is monitored the diameter deviation of each wheel in the same vehicle.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of railway wheel diameter measuring device, adopting the action mensuration, is benchmark with the wheel rim summit, measures action H value, can calculate wheel rim top radius R according to chord length 2L, again the flange height S that measures according to cross-sectional shape
dDeng geometric parameter, converse the diameter D of wheel
0, i.e. rolling circle diameter.Adopt high-precision sensor, the measuring accuracy height, simple in structure.Computing formula is as follows:
For achieving the above object, the technical scheme that the utility model adopted is: by locating rack, two special-purpose register pins, magnetic is inhaled iron mechanism and is adopted the measuring head of the method for creeping to form, wherein, two special-purpose register pins are housed on the locating rack, and magnetic is inhaled iron mechanism and measuring head.
Described special-purpose register pin is the cylinder type hollow structure of band portion four sides cut, in the tensioning screw of a band gradient is arranged, tensioning screw is fastening with register pin and locating rack.
Described magnetic is inhaled iron mechanism, comprises round sucker, forever inhales iron, guiding iron, turn-button, positioning ball spare and positioning disk.
Described measuring head comprises first pivoted arm and second pivoted arm, machine box and the roller that links to each other with second pivoted arm, one end that link to each other respectively with two scrambler output shafts.
Two register pins and magnetic are inhaled iron mechanism and have been guaranteed and the reliable location of wheel that measuring head can accurately be measured flange height by two scramblers and two pivoted arms, convert by how much and can calculate the rolling circle diameter of wheel.
The utility model has the advantages that: adopt reliable mechanical localization mechanism, convenient and reliable operation can be measured wheel diameter quickly and accurately, can by the USB dish data be linked to each other with control computer easily.Adopt LED bi-colour light prompting operation process.
