Disclosed are a method and an apparatus for monitoring a displacement adjustment state of steel rope tension balancing of a multi-rope hoist. The apparatus mainly comprises a displacement sensor (2) mounted on a steel rope tension balancing device, a signal collector/emitter (4) used for storing and sending a displacement sensor (2) signal, a pressure altimeter (8) used for detecting a shaft depth at which a hoisting vessel (3) is located, and a wireless receiving processing system (6) provided at a wellhead of a shaft. The method involves collecting a displacement adjustment amount of the tension balancing device (1) connected to each hoisting steel rope (5) and a corresponding depth location of the hoisting vessel (3) in the course of upward and downward movement of the hoisting vessel (3) via the signal collector/emitter (4), receiving data and processing and judging the maximum displacement adjustment amount for measurements in the whole hoisting process and the tension balancing device corresponding thereto and the corresponding depth via the wireless receiving processing system (6), and giving a warning when the maximum adjustment displacement exceeds a pre-set adjustment threshold. The detection method thereof is simple and convenient, the structure is simple, measurement is accurate, and reliability is high, effectively reducing the problems of wasted time and wasted energy when making manual measurements.
