Description
Technical field
The present invention relates to railroad carriage wheel detection field, more particularly to portable railway wheel tread non-roundness measurement
Instrument.
Background technology
In train travelling process, wheel tread (contact surface of wheel and rail) can generate polygon abrasion, cause vehicle
Wheel tread is non-round；The out-of-roundness of periodic measurement wheel is needed to repair or to replace.Wheel tread out-of-roundness uses mostly at present
Artificial wheel footpath ruler measurement, this kind measurement is simple and efficient, but measurement gathered data is less, and wheel footpath ruler positioning accuracy is relatively low.Also may be used
It is measured using laser displacement sensor, measurement accuracy is higher.It but need to be on the premise of non-pulling wheel by manually quilt
Measuring car wheel is jacked up or is positioned on lathe used for machining in-situ locomotive wheel, and manual rotation wheel measures；It measures frock complexity, and measuring process is numerous
Trivial, the on-the-spot test time is relatively long, is not easy to on-site rapid measurement and detection.Lathe used for machining in-situ locomotive wheel also can be used to measure：
Lathe used for machining in-situ locomotive wheel is installed in the melt pit of maintenace point, and when measurement must open vehicle to above lathe used for machining in-situ locomotive wheel, by melt pit not
Fall to take turns lathe to measure wheel directly over it.Lathe fix it is irremovable, it is necessary to vehicle stop operation carry out measured with bed,
And the vehicle in being runed on circuit cannot measured with vehicle, it is complicated for operation, time-consuming, laborious.
The content of the invention
The object of the present invention is to provide a kind of portable railway wheel tread out-of-roundness rapid measurement device, which is convenient for
Carrying, easy to operate, high certainty of measurement, the favorable reproducibility of test data；Can easily various railway carriages be measured with vehicle at the scene
Wheel tread out-of-roundness.
The technical solution adopted by the present invention to solve the technical problems is that a kind of portable railway wheel tread out-of-roundness is fast
Fast measuring instrument, composition are：The right side of vertical frame plate is equipped with front jockey wheel and rear directive wheel, front jockey wheel and rear guiding
The periphery of wheel is the concave surface coordinated with the wheel rim of tested wheel；The left end of the axis of directive wheel through frame plate is equipped with rotation afterwards
Formula encoder；The left part of cross bar is fixed on the top of frame plate, and the right end of cross bar is fixedly connected with the shell of micrometer；Micrometer
Downward probe is contacted with the tread of tested wheel；The right side of frame plate is also equipped with three Universal casters；Rotary encoder
It is electrically connected with data acquisition device of the micrometer with rack back.
Working process and principle of the invention are：
During test, vehicle is stopped at any position on circuit, and survey crew holds frame plate, and forward and backward directive wheel is leaned against
On tested wheel, and the periphery of forward and backward directive wheel is made to be bonded completely with the wheel rim of tested wheel；And make three Universal casters tight
Paste the left surface of forward and backward directive wheel.The probe of micrometer is then placed in tested wheel tread, then micrometer is returned to zero.Operation
Frame plate makes three Universal casters of frame plate be close to the rolling of wheel left surface, and makes the forward and backward directive wheel edge of frame plate tested
The wheel rim rotation of wheel.
In frame plate rotary course, the rotary angle signal of rear directive wheel is transmitted to data acquisition device by rotary encoder；
Data acquisition device receives wheel radial displacement (diameter difference of the wheel) letter of rotary angle signal, i.e. triggering collection micrometer
Number；Finally by the displacement signal data value measured and corresponding rotary angle signal data value be sent into computer disposal to get to
The out-of-roundness of tested wheel.
Compared with prior art, the beneficial effects of the invention are as follows：
First, portable railway wheel tread out-of-roundness instrument for quick measuring of the invention is led by forward and backward on frame plate, plate
It is simple in structure, light and handy, can be carry-on to wheel, three Universal casters, rotary encoder, micrometer, data acquisition device composition
It carries, the wheel out of round degree for realizing any position vehicle to being stopped on circuit (is not dismantled, no with vehicle, scene, non-pulling wheel
Jack up) measurement.
2nd, rotary encoder measures the rotational angle of rear directive wheel shaft, the displacement (wheel of synchronous triggering collection micrometer
Diameter difference) signal, obtain the out-of-roundness of wheel；The out-of-roundness of wheel is unrelated with the angular speed that frame plate rotates, that is, measures
In journey the speed of gantry rotation on measurement result without influence；Measurement data is accurately reliable, reproducible.The precision of micrometer is up to 1 μ
M, high certainty of measurement.
3rd, above-mentioned directive wheel is designed using reversed wheel rim, and guiding wheel tread and tested wheel rim exterior contour can be made complete
Good engagement, it is ensured that directive wheel rotational angle is corresponded with tested wheel circumferential position, ensures the accurate, reliable of measurement.Meanwhile
Directive wheel can realize fast assembling-disassembling, replace the directive wheel of different shaped face wheel rim, you can realize measurement different shaped face wheel not
Circularity.
The plane and the left surface of front jockey wheel and the left side of rear directive wheel that the top of three above-mentioned Universal casters is formed
Face is same plane.In this way, measurement plane can be accurately positioned, ensure that the test plane in test process does not shift, test
As a result it is more accurate, reliable.Meanwhile the rotation by ball scrolling realization in measuring basis plane, frictional force is reduced, makes behaviour
It is more convenient.
The concrete structure that the left part end of above-mentioned cross bar is fixed at the top of frame plate is：The left part of cross bar is provided with the logical of bar shaped
Slot, connection bolt are fixed on through straight slot at the top of frame plate.
Adjust position of the connection bolt in straight slot, you can realize and the axial position stepless-adjustment of wheel is being tested to micrometer
Section, the out-of-roundness of the test plane of the convenient axially different distance to same wheel are tested.
The present invention is described in further detail with reference to the accompanying drawings and detailed description.
