The invention provides a grinding block loading and unloading device, a tread sweeper and a railway vehicle, and belongs to the technical field of railway vehicle equipment. The invention provides the grinding block loading and unloading device of the tread sweeper. The grinding block loading and unloading device is used for assembling and disassembling a grinding block. The tread sweeper comprises a brake head with a wedge-shaped mounting groove, a limiting check block and a check block locking assembly. The wedge-shaped mounting groove is used for matching a wedge-shaped mounting block of the grinding block in a wedge shape and is arranged in the approximate tangential direction of a wheel acted by the grinding block; the check block locking assembly can position and install the limiting check block on the brake head in an unlocking mode, so that the limiting check block can limit the wedge-shaped mounting block to slide in the wedge-shaped mounting groove in the approximate tangential direction. The grinding block loading and unloading device is low in mounting space requirement in the axis direction of the wheel, stable and reliable in mounting and long in service life.
本发明提供一种研磨块装卸装置、踏面清扫器和轨道车辆,属于轨道车辆装备技术领域。本发明提供一种踏面清扫器的研磨块装卸装置,其用于安装和拆卸研磨块;该踏面清扫器包括:具有楔形安装槽的闸瓦托、限位挡块和挡块锁定组件;其中,所述楔形安装槽用于与所述研磨块的楔形安装块楔形配合并沿所述研磨块所作用的车轮的大致切线方向布置;所述挡块锁定组件能够将所述限位挡块可解锁地定位安装在所述闸瓦托上,以至于限位挡块能够限制所述楔形安装块在所述楔形安装槽中沿大致切线方向滑动。本发明的研磨块装卸装置在车轮的轴线方向的安装空间要求小、安装稳定可靠、使用寿命长。
