The invention belongs to the technical field of rail transit equipment, and particularly relates to a one-piece type side guard plate device mainly structurally comprises a side guard plate assembly, a side guard plate upper support assembly, a side guard plate lower support assembly, a roller assembly and a connecting rod assembly, and a spring with a buffer function is arranged between the side guard plate lower support assembly and a side guard plate lower mounting seat. The problems of abnormal sound and advanced fatigue damage of the side guard plate assembly caused by large vertical relative motion amplitude and continuous change of a vehicle are solved, excessive impact between the side guard plate assembly and the side guard plate lower support assembly is avoided, and the requirement for continuous change of vertical motion of the vehicle is met; the vertical movement load of a vehicle acting on the side protection plate assembly is relieved, reset restoring force is provided for a winding drum, and a more durable and comfortable riding environment is provided for passengers and vehicle workers; the one-piece type side guard plate device is simple in structure, high in practicability, convenient to assemble, disassemble, operate and maintain, good in stability and safety, long in service life, environmentally friendly in use and wide in application range.
本发明属于轨道交通设备技术领域,具涉及一种一片式侧护板装置,主体结构包括侧护板组成、侧护板上支座组成、侧护板下支座组成、滚轮组成和连杆组成,在侧护板下支座组成与侧护板下安装座之间设置了具有缓冲作用的弹簧,以避免车辆发生垂向相对运动幅度大且连续变化时造成侧护板组成异响和提前疲劳损坏的问题,同时避免侧护板组成与侧护板下支座组成之间产生过大的冲击,满足车辆的垂向运动连续变化的需要,缓解车辆作用在侧护板组成上的垂向运动负荷,并为卷筒提供复位的回复力,为乘客和车辆工作人员提供更为持久和舒适的乘用环境;其结构简单,实用性强,安装和拆卸的操作和维护方便,稳定性和安全性好,使用寿命长,使用环境友好,应用范围广。
