Grinding device and dismantling method for high-speed rail track milling and grinding car

Abstract

The invention relates to a grinding device of a milling vehicle for a high-speed rail track and a dismounting method of a grinding wheel assembly. The device comprises the grinding wheel assembly and a main grinding shaft, wherein the a locking screw and a drive pin are arranged between the main grinding shaft and the grinding wheel assembly, a main shaft flange is arranged in the shaft center of the main grinding shaft, a first dismounting hole in which a dismounting rod can be inserted is formed in the main shaft flange, a second dismounting hole communicated with the first dismounting hole is formed in the grinding wheel assembly, a block edge is arranged at one end of the dismounting rod, a through groove for the block edge to pass is formed in the first dismounting hole and the second dismounting hole, and a gear part which is used for matching the gear with the block edge when the dismounting rod is mounted at a center angle is arranged at the tail end of the first dismounting hole. The method comprises: inserting one end of the dismounting rod into the grinding wheel assembly and the main grinding shaft, and rotating the dismounting rod to enable the block edge to be clamped at the gear part of the tail end of the first dismounting hole; applying an upward load to the other end of the dismounting rod by a lifting device; and dismounting the locking screw and the drive pin between the grinding wheel assembly and the main grinding shaft to enable the grinding wheel assembly to fall over the dismounting rod, and moving away the grinding wheel assembly, to complete the dismounting.
