The invention provides an overturning protection device for an overhead line system overhauling operation vehicle. The overturning protection device comprises a protection railing assembly with a folding function, a top climbing area is arranged on the operation vehicle, and the top climbing area is composed of an operation vehicle outer side wall, an inwards-retracting inner side wall, an end plate used for connecting the end of the outer side wall and the end of the inner side wall and an inclined plate; and the inclined plate is provided with a top climbing door capable of being connected with and disconnected from the interior of the operation vehicle, the lower end of the protection railing assembly is hinged to the top of the operation vehicle, the inlet side of the protection railing assembly is located above the top climbing area, and the side wall of the operation vehicle is provided with an overturning driving piece used for driving the protection railing assembly to be overturned and folded. According to the overturning protection device, the protection railing assembly with the inlet side located above the top climbing area and having the folding function is arranged atthe top of the operation vehicle, the problem that climbing is inconvenient when personnel carry tools for operation due to the fact that the protective area of the top of the operation vehicle is small is solved, the climbing and top climbing safety is improved, and the structure of the protection railing assembly is simplified; and the manufacturing and mounting cost is low, the folded height is small, and the vehicle using requirement is met.

    提供一种用于接触网检修作业车的翻转防护装置,包括具有折叠功能的防护栏杆组件,作业车上设有登顶区,登顶区由作业车外侧壁、向内缩进的内侧壁、将外侧壁和内侧壁端部连接的端板和斜板组成,斜板上设有可与作业车内部通断的登顶门,防护栏杆组件下端铰接于作业车顶部且防护栏杆组件的入口侧位于登顶区上方,作业车侧壁上设有用于驱动防护栏杆组件翻转折叠的翻转驱动件。本发明通过在作业车顶部设置入口侧位于登顶区上方并具有折叠功能的防护栏杆组件,解决了由于作业车顶部防护面积少而造成人员携带工具作业时攀爬不便的问题,提高攀爬登顶的安全性,简化了防护栏杆组件的结构,制造安装成本低,折叠后的高度小,满足车辆使用需求。
