The invention relates to a redundant safety braking system which comprises a winding drum, a rotating shaft and a braking mechanism, the braking mechanism comprises a braking wheel, a braking assembly, a mechanical device and an electrical device, a braking rod is arranged on the rotating shaft, the braking wheel is in threaded connection to the braking rod, the braking assembly brakes the braking wheel, and the mechanical device is in threaded connection with the mechanical device. The mechanical device pushes the brake assembly to brake the brake wheel, and the electrical device is arranged at the end of the winding drum and used for detecting the speed of the rotating shaft to drive the brake assembly to brake. According to the safety brake, the brake assembly is driven by the mechanical device or the electrical device to brake the brake wheel, when the mechanical device or the electrical device is damaged, the other device can still drive the brake assembly to brake, and then the possibility that the safety and reliability of the safety brake are reduced due to the single device is reduced.

    本申请涉及一种冗余安全制动系统,包括卷筒、转动轴以及制动机构,所述制动机构包括制动轮、制动组件、机械装置以及电气装置,所述转动轴上设置有制动杆,所述制动轮螺纹连接在制动杆上,所述制动组件对制动轮进行制动,所述机械装置推动制动组件对制动轮进行制动,所述电气装置设置于卷筒端部,所述电气装置用于检测转动轴的速度进而带动制动组件进行制动。本申请通过机械装置或是电气装置带动制动组件对制动轮进行制动,当机械装置或是电气装置出现损坏时、另一装置仍能带动制动组件进行制动,进而减少单一的装置而降低安全制动器的安全性和可靠性的可能。
