Dynamic speed detection device for steel wire rope

The utility model belongs to the technical field of steel wire rope detection, and particularly relates to a steel wire rope dynamic speed detection device which comprises a winding wheel, an outer frame pipeline is arranged below the winding wheel, the inner wall of the outer frame pipeline is connected with a limiting block in a sliding mode, and the top end of the limiting block is connected with an oiling ball in a rolling mode. The top end of the limiting block is provided with a lower slope used for rolling of the upper oil ball, a photoelectric sensor is embedded in the limiting block, the bottom of the limiting block is fixedly connected with an electric push rod used for pushing the limiting block to move, and the bottom end of the electric push rod is fixedly connected to the inner wall of the bottom end of the outer frame pipeline; the running speed of the steel wire rope can be obtained according to the rotating speed of the winding wheel, so that the running speed of the elevator is detected, the
