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. Tilt angles of the sinking platform in the x direction and the z direction can be measured in real time by using the tilt angle sensor. Therefore, rotational angles of the sinking platform in three directions can be conveniently and accurately measured.
An apparatus for measuring a rotational angle of a sinking platform, comprising a sinking platform (1) being a subject to be measured and a plurality of suspension ropes (2) and guide ropes (3) connected to the sinking platform (1) and used to suspend and elevate the sinking platform (1), wherein a carriage (4) used to guide a hoisting container is assembled on two guide ropes (3), a gyroscope (5) and a gyroscope signal radio transmitter (6) are fixedly mounted at an upper end of the carriage (4), a measured signal of the gyroscope (5) is transmitted to the radio transmitter (6) in a wired manner, a tilt angle sensor (7) and a radio signal reception processor (8) are disposed on the sinking platform (1), and the radio signal reception processor (8) receives a signal of the tilt angle sensor (7) in a wired manner and processes the signal, or receives a signal of the radio transmitter (6) in a wireless manner and processes the signal.
