Monitoring system and adjusting method of scraper machine chain tension

Abstract

The invention discloses a monitoring system of a scraper machine chain tension. The monitoring system comprises an industrial camera, an image processing module, a signal conditioning module, an industrial control computer and a scraper chain tension adjusting system, wherein the industrial camera is arranged on the side surface of a machine head sprocket of the directly facing scraper machine; the industrial camera is in signal connection with the image processing module, the captured image signal is sent to the image processing module in real time, the image processing module extracts an included angle between the center line of the scraper chain engaged on the sprocket and the extension line in the horizontal direction of the meshing position according to the image information, and sends the signal to the industrial control computer after the signal is converted into an electric signal through the signal conditioning module; and the industrial control computer adjusts the tension ofthe scraper chain tension in real time according to a control signal of the preset system output driving scraper chain tension adjusting system until a preset value is reached. According to the monitoring system, the chain tension of the heavy-load scraper conveyor can be adjusted online and adjusted in real time, normal operation of the scraper conveyor is not affected, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of underground material transportation, in particular to a scraper chain tension monitoring system and an adjustment method. Background technique [0002] Scraper conveyor is a kind of continuous transportation machine, which has the advantages of large transportation capacity, wide adaptability to the environment and simple maintenance, etc., and is widely used in coal mine fully mechanized mining face. Among them, the heavy-duty scraper conveyor is a semi-closed continuous transportation equipment that uses scraper chains to transport a large amount of bulk materials. It can be used alone or in combination with multiple machines to continuously transport large amounts of materials horizontally, inclined or vertically. It is a coal mine Indispensable transportation device for fully mechanized mining face. [0003] Although heavy-duty scraper conveyors are widely used, the existing scraper conveyors still h...

AI Technical Summary

Problems solved by technology

[0003] Although heavy-duty scraper conveyors are widely used, the existing scraper conveyors still have the following problems: First, most of the existing scraper conveyors do not have a chain tension adjustment mechanism, or use passive adjustment when the machine stops The method of tension can easily lead to inconsistent tension of the two scraper chains due to uneven material scattering during the operation of the scraper machine, and accidents such as chain drop and chain jumping; the second is that the scraper conveyors currently in practical use lack scraper chains The real-time continuous monitoring method of tension is not conducive to the online control of chain tension; the third is the lack of a safe and reliable real-time adjustment method of scraper chain tension, resulting in frequent shutdowns to adjust chain tension and reduce the working efficiency of scraper conveyors
