Abstract

The invention provides an abrasive belt type rail grinding operation control system and a grinding control method thereof. The system includes: an interconnected grinding control device and a grinding implementation mechanism; the grinding control device collects the rotational speed of the abrasive belt, the current signal of the grinding motor and the travel speed of the grinding vehicle, and generates a grinding motor control signal and The grinding force control signal is transmitted to the grinding implementation mechanism; the grinding implementation mechanism regulates the rotation speed of the grinding motor according to the grinding motor control signal, regulates the rotation speed of the abrasive belt, and regulates the grinding effect of the abrasive belt on the rail according to the grinding force control signal Force to achieve material removal on the rail surface. The system and method of the embodiment of the present invention grasp the grinding operation state in real time according to the operation signal feedback, and form a high-precision control closed loop by adjusting the rotation speed of the grinding motor and the combined action of the grinding force to realize the grinding operation of the abrasive belt type rail. The whole process is under servo control.

Description

technical field

[0001] The invention relates to the technical field of railway engineering machinery, in particular to an abrasive belt type rail grinding operation control system and a grinding control method thereof. Background technique

[0002] With the rapid development of my country's high-speed railway and the continuous improvement of railway transportation capacity, the problem of rail contact fatigue damage is becoming more and more serious. Rail grinding is an important means of rail maintenance, which can effectively repair the profile of the rail and prolong the service life of the rail. Compared with the traditional rail grinding method based on grinding wheel grinding, the rail grinding method based on abrasive belt has a series of advantages such as not easy to burn the rail, high operating efficiency, and easy recovery of grinding debris.

[0003] However, the application of abrasive belt grinding to rail grinding will bring corresponding difficulties to th...
