The invention discloses a tension compensation method and device for a hoist rope of a double-elevator-car elevator. The method includes the steps that a solenoid coil is powered on through a controller, downward attraction force is generated for a permanent magnet after a magnetic filed is generated, downward pull force is applied to two elevator cars through the two ends of a tension compensation rope, meanwhile the pull force at the two ends of a hoist rope is increased, and the specific value of the pull force at the two ends of the hoist rope is reduced, so that the double-elevator-car elevator meets the hoisting condition all the time. The tension compensation device comprises a hoisting wheel. The hoisting wheel is connected with the two elevator cars through the hoist rope. The elevator cars and the hoist rope are provided with tension sensors. The solenoid coil and the permanent magnet are arranged below the elevator cars. The top of the permanent magnet is provided with diversion sheaves. The diversion sheaves are connected with the tension compensation rope. The tension compensation rope is connected with the bottoms of the elevator cars. The permanent magnet is connected with the controller through a wire. The controller is connected with a tension sensor in a wireless manner. The tension compensation method and device can improve operation stability of the double-elevator-car elevator and have the beneficial effects of being good in safety and high in sensitivity.
