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

Embodiment Construction
[0025] The technical solutions in the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0026] Such as figure 1 with figure 2 As shown, a scraper chain tension monitoring system includes an industrial camera 3, an image processing module, a signal conditioning module, an industrial computer, and a scraper chain tension adjustment system. The industrial camera 3 is located on the sprocket 4 facing the scraper The side of the sprocket wheel of the machine head is used to shoot the image of the scraper chain engaged at the sprocket wheel of the scraper machine; the industrial camera 3 is connected with the image processing module signal, and the captured image signal is sent to the image processing module in real time, The image processing module extracts the angle between the center line of the scraper chain meshed on the sprocket and the horizontal extension line of the meshing point according to the ...

The invention discloses a scraper machine chain tension monitoring system, which includes an industrial camera, an image processing module, a signal conditioning module, an industrial control computer and a scraper chain tension adjustment system. side; the industrial camera is connected to the signal of the image processing module, and the captured image signal is sent to the image processing module in real time. The angle between the extension lines in the direction, and the signal is converted into an electrical signal by the signal conditioning module and then sent to the industrial control computer; the industrial control computer outputs the control signal to drive the tension adjustment system of the scraper chain according to the preset system to control the tension of the scraper chain in real time. Adjust until it reaches the preset value. The invention can monitor and real-time adjust the chain tension of the heavy-duty scraper conveyor without affecting the normal operation of the scraper conveyor and improve its working efficiency.
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...
