摘要： Systems and methods for detecting a layer-to-layer transition of a lifting steel wire rope on a reel are described. The system includes a reel assembly for winding a steel wire rope on a reel and a tensioning assembly for tensioning a segment of said steel wire rope. The system further includes a loading assembly and a lead screw sliding assembly. The loading assembly provides a vertical loading to the tensioning assembly so as to generate a loading force between the tensioned steel wire rope and the steel wire rope wound around the reel. The lead screw sliding assembly drives the tensioning assembly so as to move on a horizontal guide rail to generate a relative displacement between the tensioned steel wire rope and the steel wire rope wound around the reel. The tensioning assembly is connected to the loading assembly via a first threaded rod and a static torque sensor.

摘要： A vibrating type hard rock cutting mechanism with a function of directional high-speed abrasive jet advanced slitting includes a disc-shaped hob, a cutting main shaft and a valve plate. When the vibrating type hard rock cutting mechanism works, an outlet of a high-pressure abrasive jet generating system is communicated to a cutting mechanism abrasive jet inlet. An abrasive jet enters an abrasive jet nozzle through flow channels in the valve plate, the cutting main shaft and the disc-shaped hob and forms a directional high-speed abrasive jet. The cutting main shaft is directly driven to rotate by an axial permanent magnet motor. The cutting mechanism enables the disc-shaped hob to vibrate under the action of a vibration motor. A macro crack is formed on a rock mass by rotating the abrasive jet. The rotating disc-shaped hob can be wedged into the formed crack in a vibration manner by swinging the cutting mechanism.

摘要： An apparatus includes a current excitation source, a roadheader telescopic protection cylinder, an electric rotating apparatus, auxiliary cutting teeth, a cutting head entity, a transmission shaft, an optical fiber ring protective housing, an optical fiber ring, an optical fiber current sensor control unit and a recovery electrode. The apparatus transmits an auxiliary current Ie and a monitoring current Id to a coal seam. The auxiliary current Ie and the monitoring current Id are homologous currents that are incompatible, and the auxiliary current Ie squeezes the monitoring current Id, so the monitoring current Id monitors the environment of the coal seam. The monitoring current Id flows to the coal seam as, and a return current If flows through the transmission shaft and a roadheader expansion part. The optical fiber ring measures the return current If, when the roadheader is heading forward and encounters abnormal geological bodies.
