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： Disclosed are an online monitoring system for a crack on a hoist spindle and an operation method thereof. The system comprises: a rope power part, a crack detection part, a wireless transmission part, and a computer. The rope power part comprises two traction ropes, two guide wheels, two stepper motors, and two stepper motor drivers. The crack detection part comprises a spiral tube guide rail, a sliding body, and an ultrasonic generator. The wireless transmission part comprises three zigbee wireless sensing modules. The zigbee wireless sensing modules receive instructions from the computer and transmit the instructions to the stepper motor drivers to control the motors to rotate. The stepper motors drive the guide wheels to rotate to realize the winding of the ropes, so as to pull the sliding body to slide on the spiral tube guide rail. The ultrasonic generator clamped on the sliding body monitors the rotating spindle along the spiral tube guide rail. The zigbee wireless sensing modules transmit the detected data to the computer in real time. The present invention can effectively monitor a hoist spindle in time before a failure occurs, thereby avoiding safety accidents.

摘要： A hydro-viscous speed regulating device for heavy-load start of a belt conveyor is provided. An input shaft and an output shaft are connected through a spline tube, an inner friction plate set, and an outer friction plate set. The inner and outer friction plate sets are controlled by an inner oil cylinder and an outer oil cylinder respectively. Oil inlet and oil return of the inner oil cylinder and the outer oil cylinder are controlled by an oil inlet valve core and an oil return valve core automatically. During starting process, pressure oil enters into the outer oil cylinder, and pushes the outer friction plate set to be engaged to provide torque required by the output shaft. After the starting process is completed, the revolving speed of the output shaft rises; the oil inlet valve core and the oil return valve core move outward under the effect of a centrifugal force; the pressure oil enters into the inner oil cylinder and pushes the inner friction plate set to be engaged to provide torque required by the output shaft, and at the same time, oil returns to the outer oil cylinder. That is, during starting process, the outer friction plate set provides large torque required for start, and the inner friction plate set provides small torque during normal operation. The present invention achieves automatic switching between different torque required for start and normal operation. Moreover, the present invention has a compact structure, reliable performance, and low costs, and is applicable in a wide range.

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.
