A steel wire rope is arranged around a periphery of the square structure. A power system, a friction-and-wear apparatus, a brake-and-wear apparatus, and a tensioning apparatus are sequentially mounted from left to right on a bottom layer of the square structure. A bearing signal collection system, a tension sensor, an excitation apparatus, and a steel-wire-rope image collection system are sequentially mounted from left to right on a top layer of the square structure. The steel wire rope sequentially passes through all the apparatuses or systems and is driven by the power system to perform circling.

摘要： The present disclosure discloses a time service and positioning network system for an underground chain-shaped large space in a coal mine. The system adopts a base station-level network internal time synchronization method which takes an optical fiber time service as a main part and takes a satellite time service as an auxiliary part to construct a time service and positioning network system with an unified time within the ad-hoc network base stations, based on the ad-hoc network base stations linearly arranged in the underground chain-shaped large space in the coal mine. Through the network construction, the network stabilization and the network application, the system unifies the time reference of the base station-level network and improves the positioning accuracy of the network application by utilization of the base station-level network internal time synchronization method. The system integrates the time service and positioning network system suitable for the underground coal mine and expands the network applicability based on an existing underground communication ring network.

摘要： The present invention discloses a hoisting container pose control method of a double-rope winding type ultra-deep vertical shaft hoisting system. The method comprises the following steps of step 1, building a mathematical model of a double-rope winding type ultra-deep vertical shaft hoisting subsystem; step 2, building a position closed-loop mathematical model of an electrohydraulic servo subsystem; step 3, outputting a flatness characteristics of a nonlinear system; step 4, designing a pose leveling flatness controller of a double-rope winding type ultra-deep vertical shaft hoisting subsystem; and step 5, designing a position closed-loop flatness controller of the electrohydraulic servo subsystem. The present invention has the advantages that a system state variable derivation process is omitted, so that a design process of the controllers is greatly simplified. The response time of the controllers can be shortened, and a hoisting container can fast reach a leveling state. In an application process of the system, sensor measurement noise and system non-modeling characteristics can be amplified through state variable derivation, so that tracking errors can be reduced through design of the flatness controller. A control process is more precise, and good control performance is ensured.

摘要： The present invention relates to a horizontally movable vertical shaft rope guide and a regulating method thereof which are suitable for guiding of hoisting containers in vertical shafts. The vertical shaft rope guide comprises a hoisting rope, and two hoisting containers suspended from the tail ends of the hoisting rope, wherein, cage guide ropes are led through guide cage lugs arranged on the two sides respectively, a tensioner arranged on the ground at the shaft top is connected to the upper end of each cage guide rope, and a connector arranged under a steel slot at the shaft bottom is connected to the lower end of each cage guide rope; a hydraulic cylinder is connected at the other side of each tensioner and the corresponding connector, and the hydraulic cylinder is connected to the tensioner or connector. During hoisting in the vertical shaft, the hydraulic cylinders are controlled to act in advance, to push the tensioners or connectors to move towards the center between the two hoisting containers, so that the cage guide ropes led through the guide cage lugs on the two sides of the hoisting containers get close to each other at the same time and wrap the hoisting container; thus, the horizontal displacement of the hoisting containers is restrained, and the impact of air flow on the two hoisting containers is minimized when the two hoisting containers meet.
