摘要： A device for cage jamming buffer of large-tonnage hoisting system of ultra-deep shaft is provided. End cage jamming buffer mechanisms are added at both ends of an automatic wire rope tension balancing mechanism, wherein the end cage jamming buffer mechanisms include an end buffer module and an end fixing module, and the end buffer module and the end fixing module are respectively mounted on shafts of the automatic wire rope tension balancing mechanisms at two ends. The end buffer module mainly consists of a buffer bearing pedestal, a limit block, a buffer block, and a stop block sequentially mounted on the shaft of the automatic wire rope tension balancing mechanism at one end. The end fixing module mainly consists of a fixing bearing pedestal and a fixing block mounted on the shaft, wherein the fixing bearing pedestal is connected to a transmission gear by an adjusting bolt, and the fixing block is located between the transmission gear and the fixing bolt.

摘要： 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.

摘要： A chain fault diagnosis system and a chain fault diagnosis method for a scraper conveyor are provided. The diagnosis system includes a strain rosette attached on a top end surface of each sprocket tooth of the scraper conveyor. The strain rosette is connected to a signal gathering unit fixed on a scraper conveyor roller through a shielded conductor, the signal gathering unit sends a gathered signal to a wireless receiving device by means of wireless transmission, and the wireless receiving device transmits the gathered signal obtained thereby to an industrial control computer through a USB interface. The diagnosis method includes the following three steps: chain dislocation/skip fault judgment, chain breakage fault judgment and chain seizure fault judgment. A comprehensive monitoring of the chain state of the scraper conveyor is performed by measuring strain magnitudes in different directions of the sprocket tooth in real-time, transmitting the gathered signal to the industrial control computer via a wireless transmission method and dynamically diagnosing the faults of seizure, dislocation, skip and breakage of the scraper conveyor chain based on the obtained strain data.
