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.

Abstract: The present invention discloses a gas-powder separation three-phase jet flow fire monitor system, including a gas-powder separation three-phase fire monitor head, a filter, a nitrogen pressurization apparatus and a dry powder tank. The dry powder tank is connected to a gas-powder mixture inlet pipe of the gas-powder separation three-phase fire monitor head through a pipeline. A nitrogen outlet pipe of the gas-powder separation three-phase fire monitor head is connected with one end of the nitrogen pressurization apparatus through the filter. The other end of the nitrogen pressurization apparatus is connected with the dry powder tank. The present invention is simple in structure and convenient to use. A cyclone separation apparatus of a dry powder pipeline of the fire monitor may separate nitrogen from conveyed ultrafine dry powder to enable the ultrafine dry powder to be fully mixed with a water-based fire extinguishing agent, thereby reducing an atomization degree of jet flow and enlarging a range of the fire monitor. In addition, the separated nitrogen enters the dry powder tank for recycling after being pressurized by the pressurization apparatus, thereby reducing the fire extinguishing cost.

Abstract: Disclosed is a method for estimating tension of a chain of a scraper conveyor, belonging to a method for estimating chain tension. The method comprises the following steps: embedding strain sensors in a plurality of scrapers of a scraper conveyor to measure the tension of weak coupling points between the scrapers and chains, converting acquired sensor signals into data signals through an A/D conversion unit, transmitting the data signals to a data control center using a wireless transmission module, further processing the tension data information of the weak coupling points through the data control center, establishing a chain tension distribution model, and determining an the estimated tension of the chain of the scraper conveyor. The method provided by the present invention is simple, efficient and practical, and the estimation of tension of the whole continuous moving chain is completed by the tension measurement at limited positions of the chain. The chain of the scraper conveyor is meshed with a sprocket and continuously moves in a middle trough and its tension also changes in real time along with the load; the strain sensors are arranged on the scrapers to measure the tension of the weak coupling points between the scrapers and the chains, and the estimation of tension of the whole chain is completed by tension measurement at limited positions on the chain.

Abstract: 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.
