Abstract: The present disclosure discloses a scene self-adaptive method for controlling an unmanned driving of a monorail hoist transportation robot. The method comprises the following steps: constructing an industrial internet of things platform for a monorail hoist; constructing a digital twin system for the monorail hoist; controlling a virtual unmanned driving of the monorail hoist; establishing a shadow following model for the monorail hoist; controlling an entity monorail hoist in real time by a virtual monorail hoist; comparing the entity monorail hoist driven by data with the monorail hoist driven by a driver with the shadow following mode; and designing a self-adaptive program for complex scenes: improving a loading velocity of a new roadway scene through merging root nodes and compressing data, implementing an environment self-adaptation, a platform self-adaptation, and a terminal self-adaptation.

Abstract: The present invention discloses a hard rock roadway and tunnel boring machine with actively rotating hobs, including a rack provided with a crawler track unit. The rack is provided with a hydraulic power unit and a high-pressure abrasive jet generation system connected therewith. A transmission box is fixedly arranged at one of ends of the rack. The transmission box is provided with two input shafts and one output shaft. The input shafts are connected with planetary reduction mechanisms. Input ends of the planetary reduction mechanisms are connected with cantilever disc driving motors. A cantilever disc is fixed to the output shaft. Four cantilevers are hinged to the cantilever disc. Cantilever driving motors are further arranged on the cantilever disc. Actively rotating hob devices are arranged at ends of the cantilevers away from the cantilever disc. The transmission box is further provided with rotary sealing devices.

Abstract: Disclose are a roadway/tunnel excavation robot and an automatic cutting control method. The robot includes a rack, a moving platform, a supporting and stabilizing mechanism, a milling mechanism, a telescoping mechanism, an inclined cutting feed adjusting mechanism, a horizontal swinging mechanism, a lifting mechanism and a controller. The milling mechanism includes a drive unit, a milling shaft, an eccentric rotary casing, a high-pressure jet nozzle unit, a tension and compression sensor and a direction sensor. Through the deflection of a center line of an inner hole of the eccentric rotary casing, the milling mechanism drives a milling cutter head to carry out a rotational oscillation motion for rock breaking; and the milling cutter head is in discontinuous contact with a rock mass. The telescoping mechanism, the inclined cutting feed adjusting mechanism, the lifting mechanism and the horizontal swinging mechanism are controlled such that the milling mechanism performs coal rocks milling.

Abstract: 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.

Abstract: 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.
