The invention provides an anti-overturning device for a railway engineering vehicle and the railway engineering vehicle. The anti-overturning device comprises a hanging seat, a traction seat and a rail clamping device. The rail clamping device comprises a middle seat, a supporting wheel and two rail clamping assemblies, the middle seat is connected to the hanging seat through a length adjusting assembly, the supporting wheel is used for supporting the top of the steel rail, and the two rail clamping assemblies are used for being limited to the two sides of the steel rail. The rail clamping device is movably connected to the hanging base through a length adjusting assembly, and a middle base of the rail clamping device is movably connected to the traction base. The length adjusting assembly can be adjusted according to the actual installation position of the lifting seat on a vehicle body, when the vehicle is in a normal road condition, the length adjusting assembly must be provided with allowance and cannot be tensioned, when the vehicle is in an overturning critical point, the length adjusting assembly must be tensioned, and at the moment, the lifting seat applies upward rail grabbing force to the rail clamping device through the length adjusting assembly; and the traction seat can apply force in the vehicle advancing direction to the rail clamping device, so that the rail clamping device advances on the steel rail along with the vehicle.
本申请提供一种铁路工程车辆防倾覆装置及铁路工程车,防倾覆装置包括:吊座、牵引座和夹轨装置。夹轨装置包括中间座、支撑轮和两个夹轨组件,中间座通过长度调节组件连接于吊座,支撑轮用于支撑于钢轨的顶部,两个夹轨组件用于限位于钢轨的两侧。夹轨装置通过长度调节组件可活动地连接于吊座,夹轨装置的中间座可活动地连接于牵引座。长度调节组件可根据吊座在车体上的实际安装位置调节,当车辆在正常路况时,长度调节组件须留有余量不能拉紧,当车辆在倾覆临界点时,长度调节组件须拉紧,这时吊座通过长度调节组件对夹轨装置施加向上的抓轨力,达到防倾覆的目的,牵引座能对夹轨装置施加车辆行进方向的力,使夹轨装置跟随车辆在钢轨上行进。
