Patent number: 10870559Abstract: 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.Type: GrantFiled: November 13, 2017Date of Patent: December 22, 2020Assignees: CHINA UNIVERSITY OF MINING AND TECHNOLOGY, XUZHOU COAL MINE SAFETY EQUIPMENT MANUFACTURE CO., LTDInventors: Guohua Cao, Yandong Wang, Zhencai Zhu, Weihong Peng, Gang Shen, Shanzeng Liu, Chunli Hua, Zhenhua Jiang, Xuan Dong
