    Abstract：In order to prevent beam oil pumping unit brake from sliding and assure the safety of operating personnel and equipment during oil pumping unit maintenance，it is necessary to make clear causes of oil pumping unit sliding and identify brake sliding hazards. In order to avoid common sliding phenomenon，an external contracting brake anti-sliding device has been invented according to the gear meshing force principle and the plane-pivot four-bar linkage principle. Briefly described is the operating principle and function of this device. This device，easy to operate，can avoid the oil pumping unit brake from slipping due to accidental failure of the brake friction wheel and eliminate safety accidents resulting from brake slipping.
