The invention provides a friction turnover type road and bridge overload protection safety device and an operation method thereof. The device comprises a pedestal, a turnover sliding block, a speed control limiting spring, a reset unit, a constant force supporting unit and an overload alarm unit, the pedestal supports the turnover sliding block and the constant force supporting unit, the speed control limiting spring and the reset unit are arranged between the pedestal and the turnover sliding block, the turnover sliding block can form a slope of about 5% to 10% according to the load of a vehicle, so that the vehicle is forcibly restricted, and meanwhile, the overload alarm unit gives out an overload alarm. Whether the vehicle can get on a bridge or not is automatically controlled by judging whether the interface friction force and the total weight of the vehicle are balanced or not, the load of the vehicle getting on the bridge is limited, the bearing burden of the bridge is relieved, and bridge damage caused by vehicle overload can be effectively prevented.

    本发明提供一种摩擦翻转式的道路桥梁防超载保险装置及其运行方法,该装置包括台座、可翻转滑块、控速限位弹簧、复位单元、常力支撑单元和超载报警单元,所述台座支承所述可翻转滑块和常力支撑单元,并在所述台座与所述可翻转滑块之间设置所述控速限位弹簧和所述复位单元,根据车辆载重,可翻转滑块可以形成5%~10%左右坡度,从而强制车辆限行,同时,超载报警单元发出超载警报。本发明利用界面摩擦力与车辆总重是否平衡来自动控制车辆是否可以上桥,限制了上桥车辆的荷载,减轻了桥梁承载负担,可以有效防止由于车辆超载引起的桥梁损坏。
