The working principle of the plane grinding equipment for the contact rail 910 is as follows: firstly, a worker drags the supporting mechanism 100 to a contact position of an adjacent contact rail 910, then rotates the first connecting rod 410 to enable the locking head 430 to be clamped in the locking hole 450, then the controller 800 controls the second driving member 600 to move to adjust the position of the adjusting member 350, then manually rotates the driving handle 356 to drive the driving screw 353 to rotate, so as to push the pressing plate 352 to push the annular abrasive belt 340 to move towards the contact rail 910 and finally to be in contact with the contact rail 910, and spells the movement of the first driving member 500 controlled by the controller 800 to drive the driving roller 320 to rotate, so as to drive the annular abrasive belt 340 to move and polish the contact rail 910;

when the next position is polished, the controller 800 controls the first driving member 500 and the second driving member 600 to stop working, and then manually drives the first connecting rod 410 to rotate, so that the locking head 430 leaves the locking hole 450, and then pulls the supporting mechanism 100 to move to the contact position of the next contact rail 910.

To sum up, the utility model discloses it can move on touch rail 910 through supporting mechanism 100 to drive grinding machanism 300 along touch rail 910 axial motion, grinding machanism 300 self can move at the in-process of motion, thereby carry out quick polishing to the contact department of adjacent touch rail 910, can enough reduce intensity of labour, improvement work efficiency that can be very big again.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
