The invention discloses a mounting structure of a railway vehicle door. The mounting structure comprises a four-connecting-rod mechanism, an adjusting mechanism and a limiting mechanism. The adjusting mechanism comprises a rack and a mounting shaft, one end of the mounting shaft is mounted on the rack through a mounting hole, the other end of the mounting shaft is connected with the four-bar mechanism through a bearing, and the bearing serves as a motion fulcrum of the four-bar mechanism; the limiting mechanism comprises a limiting plate, one end of the limiting plate is connected with the mounting shaft and fixed through a fastener, and the other end of the limiting plate is adjustably connected with the rack through an adjusting part; and the limiting plate can drive the mounting shaft to move and limit in the mounting hole, so that the four-bar mechanism can control the vehicle door to be smoothly opened or closed when moving. The mounting structure of the railway vehicle door is convenient to mount and adjust, capable of limiting and resistant to impact, the mounting reliability is greatly improved, and the workload of maintenance personnel is reduced; and the position of the bearing is limited, so that the plug-pull movement and the plug-out distance of the railway vehicle door are accurately controlled.
本发明公开了一种轨道车辆车门的安装结构,包括四连杆机构、调节机构和限位机构;所述调节机构包括机架和安装轴,所述安装轴一端通过安装孔安装在机架上,另一端通过轴承与四连杆机构相连,所述轴承作为四连杆机构的运动支点;所述限位机构包括限位板,限位板一端与安装轴相连并通过紧固件固定,另一端通过调节件与机架可调节连接;所述限位板可驱动安装轴在安装孔内移动并限位,使得四连杆机构运动时可以控制车门顺利打开或关闭。本发明的轨道车辆车门的安装结构既方便安装调整,又能限位、耐冲击,大大提高安装的可靠性,减少维护人员的工作量;并且通过对轴承的位置进行限位,从而精准控制轨道车辆车门的塞拉运动和塞出距离。
