The invention provides a grinding unit assembling and disassembling assembly and assembling and disassembling method, a wheel tread cleaning device and a railway vehicle. The grinding element assembling and disassembling assembly comprises a mounting pin, a mounting pin receiving part and a mounting pin locking member; the mounting pin comprises a base part and a pin part extending and protruding from the base part, and the size of the pin part is smaller than that of the base part in the extending direction of the pin part; the pin part is used for penetrating from a first side to a second side of a mounting cavity of a brake head, and the base part is used for abutting against the first side of the mounting cavity of the brake head; the mounting pin receiving part has a first mounting hole into which the receiving pin part is inserted; the mounting pin receiving part is used for receiving the pin part on the second side of the mounting cavity of the brake head; and a mounting pin locking member detachably locks the pin part of the mounting pin with the mounting pin receiving portion and restricts movement of the pin part in an extension direction of the pin part. Through the simple structure, quick assembly and disassembly, high locking reliability and high structural strength are achieved, and abrasion caused by vehicle vibration impact to the grinding element assembly and disassembly assembly can be effectively prevented.

    本申请提供一种研磨子装卸组件、装卸方法、车轮踏面清扫装置及轨道车辆。该研磨子装卸组件包括:安装销,其包括基座部分以及从基座部分延伸突出的销部分,销部分的尺寸在其延伸方向上小于基座部分的尺寸;其中,销部分用于从闸瓦托的安装腔的第一侧穿过至第二侧,基座部分用于抵靠闸瓦托的安装腔的第一侧;安装销接收部,其具有接收销部分插设其中的第一安装孔;安装销接收部用于在闸瓦托的安装腔的第二侧接收销部分;以及安装销锁定件,其可拆卸地将安装销的销部分与安装销接收部锁定,并限制销部分在其延伸方向上发生运动。本申请通过简单的结构实现了快速装卸、高锁定可靠性、高结构强度,能够有效防止车辆振动冲击对研磨子装卸组件所造成的磨损。
