The invention provides a detector and a detection method of an elevator overload protection device. The detector comprises a suspension mechanism, a hydraulic mechanism, a baseplate and an adjustable casing group, wherein the suspension mechanism comprises a suspension frame and a lifting belt used to limit the farthest distance of the suspension frame relative to a rope hitch plate; the hydraulic mechanism comprises a hydraulic jack and a pressure detector, the top end of an adjustment screw rod of the hydraulic jack is equipped with a top plate used to press against the suspension frame and make the hydraulic jack apply loads with the suspension frame as supporting during work, and the pressure detector is used to detect the value of loads applied by the hydraulic jack; the baseplate is located under the hydraulic jack and used to transmit the loads applied by the hydraulic jack; and the adjustable casing group is located under the baseplate and comprises a plurality of adjustable casings, one end of each adjustable casing is equipped with a casing used for cup-jointing of a rope hitch rod, and the other end is equipped with an adjustment mechanism which is used to adjust height of the adjustable casing. By applying the detector and the detection method of the elevator overload protection device provided by the invention, efficient and high-precision detection can be realized to the overload protection device through the rational structure and simple and convenient operations.
