Problems solved by technology
The existing chain-break monitoring device cannot effectively distinguish between the flat ring and the vertical ring in the chain, resulting in low accuracy of the signal processor in judging the broken chain. In recent years, some universities and equipment manufacturers have done some research on the chain-break monitorin...

The invention discloses a mine scraper conveyor chain breakage monitoring signal processor. The mine scraper conveyor chain breakage monitoring signal processor comprises a signal processor and a chain breakage monitoring device, the chain breakage monitoring device comprises a first Hall sensor and a second Hall sensor, and the first Hall sensor and the second Hall sensor are used for detecting flat rings and vertical rings of a left scraper conveyor chain and a right scraper conveyor chain respectively. According to the mine scraper conveyor chain breakage monitoring signal processor, the chain breakage monitoring device is high in precision and reliability and can precisely identify the flat rings and the vertical rings in the mine scraper conveyor chains, and therefore on this basis, the chain breakage monitoring device can detect information more plentifully; a counting module and a chain breakage judging module which are arranged in the signal processor and combined with time parameters and the flat ring and vertical ring quantity can accurately and reliably judge whether the scraper chains generate the breakage accident or not; and compared with an existing chain breakage fault diagnosing system, a totally different technical scheme is designed, in the technical scheme, the signal processor and the chain breakage monitoring device cooperate with each other to truly achieve industrial application of the chain breakage monitoring function, and the mine scraper conveyor chain breakage monitoring signal processor is the first case in the industry.
Description
technical field [0001] The invention relates to the technical field of mine scraper conveyor equipment, in particular to a mine scraper conveyor chain breakage monitoring signal processor. Background technique [0002] During the operation of the mine scraper conveyor, due to the complex and harsh working conditions, the scraper chain of the scraper conveyor sometimes breaks due to drastic changes in the external load. Since the scraper chain is generally composed of two chains, after one of the chains is disconnected, the scraper chain will continue to run under the traction of the other chain. And the broken chain will accumulate to varying degrees. The accumulated chain is easy to get stuck in the middle groove and be hindered when passing through a narrow space, resulting in the inability of the entire scraper chain to operate, which in turn causes a greater degree of equipment accidents. Therefore, it is necessary to monitor the operation of the scraper chain in real ...
