Abstract
The utility model relates to a double-middle-chain scraper conveyer, which comprises main shafts, a plurality of scrapers and chains. The conveyer has the following characteristics: a sprocket wheel is arranged on each main shaft, two rows of sprockets are arranged side by side on the sprocket wheel, and a chain is engaged with each row of sprockets; and the scrapers are fixed on the chains. The utility model has the following advantages: since the two chains are connected with the same sprocket wheel, the defects of asynchronous operation and ununiform stress are fundamentally solved, and thereby accidents, such as bearing overheating, chain jamming and ring sticking, cannot occur any more. The utility model with a simple structure dispenses with parts such as coupling sleeves and adapter rings, meanwhile, the main shafts and the sprocket wheels dispense with the spine structure, and are directly welded together, consequently, the fabrication cost is greatly reduced, and the machining time is greatly shortened. Since the structure is simplified, the service life of the conveyer is longer, the consumption of parts is reduced, maintenance is reduced, and normal production is guaranteed.
Description
Technical field:
The utility model relates to a kind of conveyer, the scraping transporter that use particularly a kind of industry down-hole of digging up mine.
Background technology:
At present, the down-hole of mining industries such as colliery is extensive use of scraping transporter, carries coal or ore.This scraping transporter comprises main shaft, chain, frid and scraper plate, and described main shaft comprises two semiaxis and a coupling sleeve, and the outer end of two semiaxis is provided with a drive sprocket respectively, and the inner end links together two semiaxis by coupling sleeve; Main shaft connects with the speed reduction gearing that is connected motor; All be mounted with chain on the described drive sprocket, chain constitutes closed loop between the driven sprocket on drive sprocket and the countershaft, be provided with frid between main shaft and the countershaft, article two, be provided with several scraper plates between the chain, during sprocket rotation, drive scraper plate by chain and travel forward, scraper plate with the coal on the frid or ore from countershaft one end scraping delivery to main shaft one end.This scraping transporter complex structure, drive sprocket is connected by the male splines of female splines and semiaxis, owing to reasons such as the working accuracy of spline and assembly precisions, asynchronous, unbalance stress when causing two chain operations, bearing running hot easily takes place, even jump accidents such as chain, snap ring, directly influence normally carrying out of downhole production.
Summary of the invention:
It is stressed evenly and two medium chain scraping transporters of synchronized operation that the purpose of this utility model provides a kind of simple in structure, chain.
The realization the technical solution of the utility model is, a kind of pair of medium chain scraping transporter comprises main shaft, scraper plate and chain, it is characterized in that, described main shaft is provided with a sprocket wheel, and described sprocket wheel is arranged side by side the two row gear teeth, articulates a chain on every row gear teeth; Be connected with several scraper plates on the described chain.
The utility model has the advantages that two chains are articulated on the sprocket wheel, fundamentally solved and turned round asynchronous and defective discontinuity, thereby bearing running hot takes place never again and jump accidents such as chain, snap ring.The utility model is simple in structure, has saved parts such as coupling sleeve, coupling link, and simultaneously, main shaft, sprocket wheel have saved spline structure, and the two directly uses welding manner affixed, has significantly reduced manufacturing cost and overhours.Designs simplification also makes longer, the accessory consumption minimizing of the utility model life-span, and the maintenance maintenance amount reduces, and has ensured normally carrying out of producing.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Number in the figure: 1 main shaft, 2 sprocket wheels, 3 chains, 4 scraper plates.
The specific embodiment:
Referring to Fig. 1, described sprocket wheel 2 is arranged on the centre of main shaft 1, and sprocket wheel 2 and main shaft 1 adopt welding manner affixed; Two row's gear teeth that sprocket wheel 2 is arranged side by side articulate a chain 3 respectively, affixed several scraper plates 4 on the chain 3.
