working principle

Put the gjm-6.0 multifunctional rail finishing mill on the line rail or turnout, and the running frame of the grinder can move longitudinally on the rail or turnout under the rolling of the running wheel, driving the grinding wheel grinding head to grind longitudinally on the rail or turnout. The sliding trolley is installed on the walking frame, the following four groups of wheels are positioned on the trolley obliquely, and the wheel tread rolls laterally on the guide rail of the walking frame to drive the grinding wheel grinding head to move laterally at the rail head. The positioning of the grinding wheel grinding head at the longitudinal grinding position of the rail head adopts the cooperation of the chain mechanism on the trolley and the circular arc guide groove to guide the grinding wheel grinding head to rotate and position at any position of the rail head. The rotation angle of grinding wheel head depends on the dial. The grinding power of the grinding head of the grinding wheel is directly transmitted to the grinding wheel by the gasoline engine through the connecting shaft and the grinding wheel disc. The upper part of the grinding assembly is designed and installed with a rotating limit ball and a sink control mechanism. The feed of the grinding wheel grinding head is stably controlled through the ball screw to ensure the grinding accuracy. The full section grinding of the top surface of the whole rail head and the arc is completed by multiple longitudinal grinding of the rail head with the grinding head of the grinder.

Gjm-6.0 multifunctional rail finishing mill consists of seven parts: traveling frame assembly 1, traverse control assembly 2, rotation control assembly 3, grinding wheel feed assembly 4, gasoline engine 5, sliding trolley assembly 6 and grinding control assembly 7. See overall structure figure 1.
