The invention discloses a rope breakage safety protection device for a mining car of an inclined shaft. The device consists of two sets of braking devices with the same structure, wherein the two sets of braking devices correspond to front and rear wheels of the mining car respectively, and each set of braking device consists of a speed control device, a wheel quioning device and a rail quioning device; the speed control devices consist of braking pawls controlled by the speed of the wheels through centrifugal flail blocks; the wheel quioning devices consist of brake levers controlled by the braking pawls and braking wedge blocks; the rail quioning device consist of rail encircling blocks pulled by the braking wedge blocks through braking triggering ropes. The safety protection device has the advantages that the speed of the mining car is used as a starting signal, and the device can quickly response; in case of rope breakage, the wheel quioning devices and the rail quioning devices simultaneously act, so that double safety is provided; the device also has a safety protection function for the leftward and rightward movement rope breakage of the mining car and disconnection between mining cars; the device is compact in structure, light in weight and small in size.
