Abstract
Disclosed is a brake winch with reverse release and self-locking functions. The brake winch has a housing with first and second side walls, an accommodating space, and an auxiliary bracket part. A rotating disk is screwed in the accommodating space. A main shaft is screwed on one side of the rotating disk in an interlocking manner. A screw adapter is screwed on the second side wall, and includes an inner connection end that is assembled with the main shaft, and its external end has a threaded groove. The axial displacement of a driving screw, which is screwed on the auxiliary bracket, is matched with the difference of forward and reverse rotation to form a screwing transmission or release mode between the stud section and the thread groove. A friction driving mechanism must prompt the drive screw, the clamping plate and the screw adapter to be in a tightly synchronized state.
