Title:
SCRAPER-CONVEYOR CHAIN TENSION MONITORING SYSTEM AND ADJUSTMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2021/068472
Kind Code:
A1
Abstract:
Provided are a scraper-conveyor chain tension monitoring system and adjustment method; the scraper-conveyor tension monitoring system comprises an industrial camera (3), an image processing module, a signal conditioning module, an industrial control computer, and a scraper conveyor chain tension adjustment system, the industrial camera (3) being disposed on the side of a machine head sprocket (4) facing the scraper conveyor; the industrial camera (3) is connected to the image processing module signal, and sends a captured image signal to the image processing module in real time, and the image processing module extracts the angle between the center line of the scraper chain meshed on the sprocket (4) and the horizontal extension line of the mesh according to the image information, and, by way of the signal conditioning module, converts the signal into an electrical signal and then sends it to the industrial control computer; the industrial control computer adjusts the tension of the scraper chain in real time according to a control signal outputted by a preset system to drive the tension adjustment system of the scraper chain until a preset value is reached. The scraper-conveyor chain tension monitoring system and adjustment method can monitor online and adjust the chain tension of a heavy-duty scraper conveyor in real time, improving the operational efficiency of the scraper conveyor without affecting its normal operation.
