The invention relates to a hanging roller adverse brake, and belongs to the technical field of belt conveyers. The hanging roller adverse brake comprises a bearing plate, an outer ring and a star wheel. The star wheel is fixed to the bearing plate through a screw, and a compression spring is arranged in a groove of the star wheel; an insert is fixed to the star wheel and located below the side of the compression spring; a spring sleeve is arranged outside the compression spring; a roller is arranged above the insert, and the rear end of the roller directly faces the spring sleeve; the outer ring is arranged on the outer side of the roller; and an end cover is fixed to the outer ring through the screw, and the roller is sealed through the end cover. The hanging roller adverse brake is simple in structure and used for the belt conveyer. When the power failure suddenly happens to conveying equipment, the brake plays a role in emergent braking, materials are prevented from sliding, and therefore the equipment is protected against damage; and the hanging roller adverse brake is easy and convenient to mount, and is not required to be corrected; and the adverse brake is safe and reliable.
