Description
Technical field
The utility model relates to a kind of scrapper conveyor, particularly a kind of for transporting the chain-breaking protection device of scraping machine of the lump lime that limekiln burns out.
Background technology
At present, in soda ash production process, what lime workshop ash silo transportation device adopted is XGZ scrapper conveyor, for transporting the lump lime that limekiln burns out, because XGZ slat conveyer is used for coal washing industry, some problems in transporting the process of lime, have been there are, especially frequently there is phenomenon of rupture in chain and chain T-Ring, to production, bring larger fluctuation, simultaneously, while there is chain rupture phenomenon in slat conveyer in operational process, easily make chain rupture be wrapped in great wheel, more than 10 meter of the lighter, more than 20 meter of severe one, to service personnel, bring very large work capacity, repair time is generally at 4～5 hours.In addition, because ash silo dust is more, maintenance environment is severe, and a large amount of dust and hot environment, bring very large difficulty to maintenance equally, also increased recondition expense.
Utility model content
The utility model main purpose is to address the above problem and is not enough, provides a kind of and can in time, effectively carry out chain rupture protection, the chain-breaking protection device of scraping machine of increasing work efficiency.
For achieving the above object, the technical solution of the utility model is:
A kind of chain-breaking protection device of scraping machine; the great wheel that comprises casing, some scraper plates, connects the chain of described scraper plate both sides and drive described chain to move; described chain breakage protection device is comprised of pull switch and stay cord; described pull switch is fixed on described casing; described stay cord is installed on the top of described great wheel; described stay cord one end is connected with described pull switch, and the other end is fixedly connected with the casing at described great wheel place.
Further, described stay cord and described great wheel tangentially arrange.
Further, between the scraper plate of described stay cord and process position, described great wheel point of contact or chain, there is a gap.
Further, described gap is 10-20mm.
Further, described gap is 10mm.
Further, described stay cord is arranged on the position of described scraper plate middle upper part.
Further, described pull switch is fixed on the top cover of described casing, and the other end of described stay cord is fixedly connected with the sidewall of described casing.
Further, described stay cord is reinforcing bar.
Content to sum up, a kind of chain-breaking protection device of scraping machine described in the utility model, simple in structure; be convenient to install and maintenance, use sensitive reliably, be specially adapted to the more working environment of dust; simultaneously; this device, by the application of pull switch, can in time, effectively carry out chain rupture protection, reduces scrapper conveyor and twines great wheel phenomenon; significantly shorten the repair time; increase work efficiency, alleviate greatly worker's labour intensity and work capacity, reduce recondition expense.
Accompanying drawing explanation
Fig. 1 is the utility model scraper plate and chain position relationship structural representation;
Fig. 2 is the utility model chain breakage protection device structural representation.
As depicted in figs. 1 and 2, casing 1, scraper plate 2, chain 3, great wheel 4, pull switch 5, stay cord 6.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail:
As depicted in figs. 1 and 2; a kind of chain-breaking protection device of scraping machine; scrapper conveyor comprises a casing 1; be arranged on the below of ash silo; on casing 1, be provided with a plurality of openings, on top cover, side cover and base plate, offer along its length respectively opening (not shown), the opening on top cover with above ash silo outlet be communicated with; opening on base plate is communicated with the ash-storing bin of below, and the opening on side cover is for maintenance, blanking etc.
In casing 1, be provided with some scraper plates that be arranged in parallel 2, the both sides of scraper plate 2 connect by a chain 3 respectively, scraper plate 2 is connected with chain 3 by fastener and coupling link, chain 3 is realized circulating motion by great wheel 4 and the transmission of tail wheel (not shown), great wheel 4 is driving wheel, by motor (not shown), is driven, and driven by motor great wheel 4 is rotated, thereby drive chain 3 and scraper plate 2 circulating motions, tail wheel driven rotation when chain 3 rotates.
In the present embodiment, the specification of chain 3 adopts Φ 22*86mm, to improve the intensity of whole chain 3, improves its traffic capacity, reduce the generation of chain rupture phenomenon, meanwhile, chain 3 adopts seven pitch chains, to improve the density of scraper plate 2, further promote the transport capacity of slat conveyer, improve production production capacity.
Chain breakage protection device is comprised of pull switch 5 and stay cord 6, and stay cord 6 is arranged on the position of great wheel 4 tops, and in the present embodiment, preferably stay cord 6 is arranged on the position of scraper plate 2 middle upper parts, can certainly be arranged on the one or both sides of scraper plate 2.
Stay cord 6 and great wheel 4 tangentially settings, one end of stay cord 6 is connected with pull switch 5, the other end of stay cord 6 is fixedly connected with the sidewall of casing 1 head, for guaranteeing the service life of stay cord 6, stay cord 6 adopts the reinforcing bar of Φ 25mm, pull switch 5 is fixed on the top cover of casing 1, welds a channel-section steel on casing 1, and pull switch 5 is fixedly mounted on channel-section steel.
Between stay cord 6 and the process scraper plate 2 of great wheel 4 positions, point of contact, leave certain gap H, gap H is 10-20mm, preferably adopts 10mm, and this gap H can guarantee that scraper plate 2 can not touch stay cord 6, causes the misoperation of pull switch 5 when chain 3 normal operation.When there is chain rupture phenomenon, the chain 3 having broken is wrapped in great wheel 4, the chain 3 and the scraper plate 2 that are wound around highly change, the stay cord 6 of top is lifted, stay cord 6 affects pull switch 5, causes pull switch 5 actions, cuts off immediately the control path of motor, scrapper conveyor quits work at once automatically, and chain 3 stops being wound around.Because the time of the follow-up reforwarding row of chain rupture is shorter, at this moment chain 3 can only be wound around about 1～2 meter of left and right, work capacity and the repair time of service personnel have been greatly reduced, the repair time of scrapper conveyor can shorten nearly 1/4th compared with prior art, not only improved work efficiency, also significantly reduced recondition expense, reduced the labour intensity of service personnel, the work-hours also reducing a staff in severe working environment simultaneously.Meanwhile, pull switch 5 and stay cord 6 are simple in structure, install and maintenance all very convenient, even and in the more comparatively severe working environment of dust, also can guarantee sensitive reliably, carry out in time chain rupture protection.
As mentioned above, given scheme content, can derive similar technical scheme by reference to the accompanying drawings.In every case be the content that does not depart from technical solutions of the utility model, any simple modification, equivalent variations and the modification above embodiment done according to technical spirit of the present utility model, all still belong in the scope of technical solutions of the utility model.
