Description
Technical field
The present invention relates to a kind of rail tread and reverse the method that rail tread on gradient detection ruler and the detection line reverses gradient.
Background technology
In the laying of rail track, generally all be provided with the rail cant with respect to orbit plane of constant slope.Track switch is that the transition of rail track cross section connects, and main parts are tongue and heart rail, and its rear end is connected with other circuit by the mode of reversing, and makes the wheel smooth transition.During existing track switch is produced, be to carry out the mode and the identical gradient of circuit rail maintenance that constant slope was processed and reversed to die mould, connect with ways of connecting such as welding or joint bars again by heel end with the AT rail.Be to be the gradient that reference field detects the die mould section flange of rail with the front end AT rail flange of rail at present, determine the gradient of reversing of whole heel end, easily cause the gradient of the gradient of tread reality and the flange of rail inconsistent, quality causes negative influence to driving a vehicle.On the circuit of laying or having moved, because reference field is difficult to select, it is bigger that rail head actual reversed the natural measurement of tilt difficulty.
Summary of the invention
The technical matters that the present invention solves: provide a kind of rail tread to reverse the method that rail tread on gradient detection ruler and the detection line reverses gradient, not only improve top surface of rail and reversed the accuracy that gradient detects, and solved that top surface of rail reverses the difficult problem that gradient is difficult to detect on the existing line, guarantee the ride comfort of rail joint place transition, the comfort level of security, stationarity and passenger when the raising train is current at a high speed.
Mentality of designing of the present invention: be that centre of twist point reverses with rail tread center A point when rail reverses, the arc surface that rail head is detected model closely contacts with the rail head face, the model of rail head detection simultaneously is that rotation center and rail rotate synchronously with the A point also, and it is identical that the two reverses gradient relatively.With the rail flange of rail is reference field, before rail reverses, the B point is h1 with respect to the height of reference field on the rail head check-out console, after the A point reverses, rail head check-out console B point is h2 with respect to the height of this reference field, and the difference in height that two condition B is ordered is H=h1-h2, and the AB distance between two points is L, the B point of two condition I and II and tread center A point constitute triangle, measure rail indirectly by the relative rotation gradient H/L that calculates rail head detection model and reverse gradient.
To ask resultant error in order reducing, to improve the precision that detects, can satisfy under the prerequisite that detects requirement, increase the length of L as far as possible, so just can reduce the error that when approximate treatment, produces according to the actual detection condition.
