The invention discloses a steel rail polishing deflection angle control method. A steel rail polishing deflection angle control system comprises a deflection motor, a pressing-down guide pillar, a polishing motor, a deflection cradle, a telescopic oil cylinder, a cradle rack and a control unit. The control unit obtains an error angle between a present feedback angle of the polishing motor and a target angle preset by a host in real time, and adjusts motion of the deflection motor continuously according to the error angle, so that the polishing motor is deflected to the preset target angle, and the polishing motor carries out polishing according to the preset target angle. Thus, the technical problems of non-uniform light strips and nonstandard polishing rail contours caused by that the polishing angle is easy to change in the polishing process in a present rail polishing deflection angle control manner can be solved.
Description
technical field [0001] The invention relates to the technical field of rail engineering machinery, in particular to a rail grinding deflection angle control method applied to a rail grinding vehicle. Background technique [0002] In the 1990s, the railway department introduced several types of rail grinding trains from abroad, and the core control systems were all imported. At present, rail grinding is one of the important means of rail maintenance recognized in the world, but the cost of using an imported control system is very high, the control algorithm is closed, the accessories are expensive, and the maintenance response is slow. At present, in order to reduce the purchase, use and maintenance costs of rail grinding vehicles, the national railway department advocates the localization of rail grinding vehicles. [0003] In the prior art, the angle deflection control methods for the rail grinding vehicle mainly include the electric control method of the deflection motor ...
