The invention discloses a grinding belt pressing device for a steel rail milling and grinding vehicle. The grinding belt pressing device comprises a base, a pressing wheel assembly, a pressurization driving device and a suspension handle, wherein the base is mounted on a vehicle body; the pressing wheel assembly is provided with a supporting frame and a pressing wheel connected with the supporting frame in a rotating manner, in a working state, the wheel surface of the pressing wheel can push a grinding belt to press a steel rail and can rotate under the action of the grinding belt; the pressurization driving device is arranged between the supporting frame and the base and is used for pushing the pressing wheel down to the working state from a suspending state; the suspension handle is mounted on the supporting frame; a suspension component connected with the suspension handle in a detachable manner is arranged on the base; in the suspending state, the upper end of the suspension handle is hitched to the suspension component to provide a supporting force in the vertical direction for the supporting frame; and in the working state, the upper end of the suspension handle is disengaged from the suspension component. The invention also discloses a steel rail milling and grinding vehicle with the grinding belt pressing device.
Description
technical field [0001] The present invention relates to the technical field of track maintenance, more specifically, to a grinding belt pressurizing device of a rail milling and grinding vehicle, and also to a rail milling and grinding vehicle comprising the above-mentioned grinding belt pressing device. Background technique [0002] The rail milling and grinding machine is mainly used to grind the track of the rail car so that the track can maintain an ideal profile, so that the rail car can run more smoothly. [0003] In order to facilitate the grinding of the rail, the current grinding device generally adopts an abrasive belt wheel device, and the outer surface of the abrasive belt of the abrasive belt wheel device is a grinding surface for grinding the rail. And at present in order to make the abrasive belt outer surface can fit with the steel rail, all are to press down so that it is offset with the steel rail by the abrasive belt wheel at the two ends of the abrasive b...
