Device for detecting equilibrium coefficient of elevator and detecting method

The invention relates to the field of elevator detection and discloses a device for detecting equilibrium coefficient of an elevator and a detecting method. The device for detecting equilibrium coefficient of the elevator comprises a first clamping block, a second clamping block, a fastening assembly, a rope tractor, a rope assembly and a dynamometer. The first clamping block and the second clamping block respectively clamp a traction rope. The fastening assembly clamps the first clamping block and the second clamping block, and clamping force is respectively exerted onto the first clamping block and the second clamping block. The rope tractor is provided with a base and a traction portion, and the base is clamped onto the first clamping block. The rope assembly is provided with a rope guiding piece and a rope, and the rope guiding piece is installed on the second clamping block. One end of the rope is fixed on the first clamping block, the other end of the rope is connected with the traction portion of the rope tractor through the rope guiding piece, and the dynamometer measures tension of the rope or the dynamometer is placed on the rope guiding piece to measure resultant force exerted by the rope to the rope guiding piece.
