The invention relates to a winding engine winding drum braking device. A winding drum brake comprises an upper brake belt, a lower brake belt, a connecting plate, a brake oil cylinder and a brake oil cylinder bracket, wherein the cylinder body of the brake oil cylinder is fixed on a winding engine base through the brake oil cylinder bracket; the piston rod of the brake oil cylinder is a threaded rod and is connected with an end part of the connecting plate through a pin shaft E; a nut is mounted at the top end of the piston rod; a manual release gear is further mounted on the piston rod below the pin shaft E in a sleeving manner and comprises a bearing assembly and a hand wheel; the bearing assembly is mounted below the pin shaft E and comprises a bearing housing and a bearing; a groove allowing the bearing to be embedded into is formed in the bearing housing; the bearing is embedded in the groove. The winding engine winding drum braking device has the following advantages: the bearing assembly is additionally arranged between the hand wheel and the pin shaft E, and the sliding friction between the hand wheel and the connecting plate is converted into the rolling friction between the hand wheel and the bearing assembly, so that the manual operation is labor-saving and fast.
