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 monitoring, but In terms of practicality, no reliable solution has been formed
The Chinese invention patent with the authorized announcement number CN105858126B discloses "a system and method for fault diagnosis of scraper conveyor chain". The fault diagnosis system is theoretically feasible, but it is difficult to put it into practical use

Abstract

Disclosed is a signal acquisition and processing system for monitoring chain rupture of a mining scraper conveyor. A processor comprises a signal processor, a chain rupture monitoring device and a processor housing, wherein the signal processor is connected to the chain rupture monitoring device; and the signal processor is arranged inside the processor housing. In the signal acquisition and processing system, a housing body is integrally milled by a stainless steel block and is corrosion-resistant and good in sealing; the left side surface of a cover plate is provided with steps along the edge to meet the requirements for quick installation; and based on richer detection information from the chain rupture monitoring device, a counting module and a chain rupture judging module which combine time parameters, the number of horizontal rings and the number of vertical rings and which are arranged inside the signal processor can accurately and reliably judge whether there is a disconnectionaccident of chains of scrapers. Compared with an existing chain rupture fault diagnosis system, the invention designs a completely different technical solution. The technical solution combines the signal processor with the chain rupture monitoring device to truly realize the industrial application of the chain rupture monitoring function and is the first case in the industry.

Description

technical field [0001] The invention relates to the technical field of mining scraper conveyor equipment, in particular to a mine scraper conveyor broken chain monitoring signal acquisition and processing system. 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 th...
