Description
Technical field
The present invention relates to heavy rail straightening field, relate in particular to the true drafts of a kind of heavy rail straightening machine and measure measurer and measuring method.
Background technology
The zero degree drafts aligning method of heavy rail straightening is: without smoothing roll being carried out under stress the position of zero degree demarcation, drafts is the displacement carrying out on zero degree position.Its shortcoming is: without the accuracy of the zero degree of demarcating under stress, be subject to the impact of Mechanism Clearance, elastic-plastic deformation, rigging error etc., poor with the correlativity of true strain, can not react real drafts, can not carry out high-precision control to straightening process parameter.
In roll leveller aligning process due to Mechanism Clearance, elastic deformation, the reasons such as elastic-plastic deformation of aligning part itself, cause the actual drafts of zero degree drafts and smoothing roll to have larger difference, strong steel drafts before and after overhaul, between new and old smoothing roll changes greatly, to control this important technical parameter of drafts, just be necessary the actual drafts of smoothing roll to measure, to guarantee accuracy and the stability of drafts.
Drafts when smoothing roll zero degree drafts refers to respect to zero degree position.Smoothing roll has just contacted aligning exemplar (exemplar: with just the same by aligning part specification, and the zero degree position that the position completely straight aligning part) and under aligning exemplar pressure-less state is smoothing roll, zero degree drafts has with the influence factor that the actual drafts of smoothing roll does not conform to: (these factors all can cause reducing of the actual drafts of smoothing roll)
(1) Mechanism Clearance can not be got rid of completely: the large bearing housing hydraulic locking of top roll brings two problems, the one, at zero degree timing signal, need smoothing roll top roll to move downward and move closer to aligning part, the smoothing roll that stops during contact aligning part is depressed action, and now depress locking device, at smoothing roll, depress after stopping and can upwards locking smoothing roll bearing, after locking, smoothing roll there will be again gap with aligning part, is difficult for accurate calibration.The 2nd, locking is the macro-axis at top roll, and the little bearing of the other end does not have locking device, to the little bearing end of the top roll after stressed, bearing clearance will be embodied on straightening roll press quantity.
(2) between smoothing roll, axle sleeve, macro-axis in the gap without existing under stress.
(3) elastic deformation of the upper and lower macro-axis of stressed rear straightener, each smoothing roll.
(4) impact etc. of the elastic-plastic deformation of aligning part.
