Abstract: The present invention discloses a device and method for adjusting tension of a steel wire rope of an ultra-deep vertical shaft at a hoisting-container-end. The device includes two stages of steel wire rope tension adjusting devices provided on a hoisting container, where a primary steel wire rope tension adjusting device includes left and right steel wire rope tension adjusting devices that are symmetrically arranged, and a secondary steel wire rope tension adjusting device is provided below the primary steel wire rope tension adjusting device. By use of two stages of steel wire rope tension adjusting devices, tension on four steel wire ropes can be adjusted to equalize the tension, thus meeting the requirement for tension equalization in a hoisting process. The four steel wire ropes are equally divided into two groups.

Abstract: An apparatus and a method for measuring a rotational angle of a sinking platform. The apparatus includes a sinking platform being a subject to be measured, suspension ropes and guide ropes connected to the sinking platform, a carriage assembled on the guide ropes, a gyroscope and a gyroscope signal radio transmitter mounted at an upper end of the carriage, and a tilt angle sensor and a radio signal reception processor mounted on the sinking platform. During running of the carriage, the gyroscope keeps measuring a pose of the carriage, and a measured signal is transmitted to the radio transmitter in a wired manner. The radio transmitter transmits a pose signal of the carriage during running to the radio signal reception processor in a wireless manner. A turning angle of the sinking platform in the y direction is accurately obtained by subtracting a pose of the carriage being located at the top of the guide ropes from a pose of the carriage being located at the bottom of the guide ropes.

Abstract: A multiple-state health monitoring apparatus for critical components in a hoisting system includes a frame. The frame is a square structure formed by welding a plurality of rectangular steels. A steel wire rope is arranged around a periphery of the square structure. A power system, a friction-and-wear apparatus, a brake-and-wear apparatus, and a tensioning apparatus are sequentially mounted from left to right on a bottom layer of the square structure. A bearing signal collection system, a tension sensor, an excitation apparatus, and a steel-wire-rope image collection system are sequentially mounted from left to right on a top layer of the square structure. The steel wire rope sequentially passes through all the apparatuses or systems and is driven by the power system to perform circling. All the apparatuses or systems are used to monitor an operation status of the steel wire rope.
