Description
Technical field
The utility model relates to field of mechanical technique, particularly a kind of flight chain chain rupture failure detector.
Background technology
The transmission of the scrapper conveyor that prior art provides drives the chain directed circulation that scraping blade is housed to move by reductor, thus reach the dust in scraper plate body is transported to specified point.The length of chain can be tens meters and arrive hundreds of rice, and what carry chain is a set of chain wheel set in about 2 meters, interval in scrapper conveyor.Chain wheel set is fixed on scrapper conveyor by axle and bearing, and chain drops on sprocket wheel by gravity, and such structure, under scrapper conveyor long-time running uses, there will be following a few point failure:
1, the chain of chain wheel set carrying is an entirety, and the number of bearings of chain wheel set is various, so the impaired necrosis of the indivedual bearing of as easy as rolling off a log appearance, as long as have a place to break down will affect the operation of whole system, and overhauls pretty troublesome.
2, chain is attached on sprocket wheel by gravity, hinders, just there will be chain jamming situation if receive object larger a little during operation.
3, the installation of chain wheel set is cumbersome, and requires that every bar sprocket wheel that chain contacts all on same vertical surface, if sprocket wheel is alignment or loosening when using, then will can cause falling chain.
4, as there is falling the situation of chain, de-chain, maintenance person must enter investigation in scrapper conveyor, maintenance, more time-consuming, also cumbersome.
The flight chain chain rupture failure detector that prior art provides: when any one ruptures chain in total length, when only having breaking part to pass through to detect sprocket wheel, chain rupture fault just can detect, and to the stretching of chain or laxly cannot to detect, chain rupture fault detection slow or (relax) stretched to chain cannot detect the damage or distortion that will bring scraper plate and chain in scraper plate discharging process, final increasing maintains difficulty.
