Description
Technical field
The invention belongs to the slat conveyer technical field, specifically relate to a kind of The middle pan of scraper conveyor.
Background technology
Along with the raising of coal mine fully-mechanized mining technology, slat conveyer is heavy, high-power towards (surpassing), the high reliability direction develops.The general-duty The middle pan of scraper conveyor is a unitized construction, generally comprises the fastening baffle plate ledge that is connected as a single entity, shovel board slot group, middle plate and base plate.The scraper plate cochain road on middle plate top is as defeated coal channel, and the life-span of its structural constituent is the key of decision intermediate channel whole service life.Wherein middle plate bears the member from the hydraulic support horizontal thrust when being the slat conveyer propelling, is again the carrier that transports coal.So middle plate except will having certain rigidity, intensity, also will possess good resistance to abrasion; Equally, the baffle plate ledge also requires to have good resistance to abrasion with shovel board slot group.In recent years, though the application of the constantly perfect and new material of technology, the wear resisting property of framing members such as middle plate increases substantially, and the slat conveyer fault that is caused by middle plate and ledge wearing and tearing still accounts for higher proportion with damaging.And existing its baffle plate ledge of intermediate channel that uses, shovel board slot group, middle plate and base plate are integral type; When central plate or ledge can not be worked because of wearing and tearing, must will damage the intermediate channel integral replacing at parts place, mining face under mine whenever changes a joint intermediate channel in the colliery; The time that needs an about class; Not only time-consuming, production efficiency is low, and productive costs is high.Be to prolong the service life of intermediate channel, the patent No. is that 200920019382.7 Chinese patent discloses a kind of coalcutter intermediate channel, is provided with replaceable wear-resistant function product in the groove upper groove body of center; This is wear-resistant, and function product and basic design spare link together through welding or bolted; But the wear-resistant function product of this " C " shape structure can only could take out perhaps via the intermediate channel two ends and pack into when changing, and can not install from direct replacing suitable for reading; Even if changing a joint member also must all open intermediate channel two ends transom; Waste time and energy, operation inconvenience, and also the scraper plate machine is after use; Intermediate channel very easily is out of shape, and makes troubles also for the replacing of abrasion-proof structure; Be the intermediate channel of this structure again, its notch is protection not, and its resistance to abrasion is also relatively poor, after the notch wearing and tearing, still need change the whole middle groove.Application number is that 201010608258.1 one Chinese patent application discloses a kind of scraper plate machine and intermediate channel thereof, and it is that ceramic bar is set on middle plate, with plate resistance to abrasion in improving; This conveyer mechanism fabrication technique is complicated, cost is high, and ledge can not get protection with notch, and its integral body is wear-resisting not strong yet; And after the ledge wearing and tearing; Also need integral replacing, productive costs is high, the effort of taking a lot of work.
Summary of the invention
The technical matters that the present invention will solve provides a kind of wear-resistant protection assembly that is provided with, and can change wear-resistant components, the The middle pan of scraper conveyor of complete machine long service life fast.
For solving the problems of the technologies described above; The present invention includes the intermediate channel cell body, said intermediate channel cell body comprises baffle plate ledge, shovel board slot group, middle plate and the base plate that is connected as a single entity, and is provided with the lining groove in the vallecular cavity on middle plate top; Its constructional feature is that said lining groove comprises lining trough floor and the side plate that is fixed in lining trough floor Width both sides; The side plate top is connected with wing plate, and lining groove vallecular cavity is scraper plate cochain road, and the said wing plate outside is provided with spacing dop; The angle of said intermediate channel ledge inner face and middle plate plate face is not less than 90 degree, and the baffle plate ledge is helped with the shovel board slot and is equipped with and the cooresponding spacing bayonet socket of described spacing dop; In the vallecular cavity on plate top, lining trough floor and middle plate joined during said lining groove integral body was landed in, and side plate and intermediate channel ledge join, and wing plate and intermediate channel ledge end face join, and spacing dop is cooresponding to be landed in the spacing bayonet socket.
Said lining groove wing plates on two sides is provided with screw, and the angle of intermediate channel ledge inner face and middle plate plate face is 90 degree.
Described lining trough floor termination is provided with in abutting connection with joining seam; Described lining trough floor termination be arc tenon or notch in abutting connection with joining seam.
Be provided with depression above the plate in described, said base plate cross section is matrix.
After adopting said structure, owing to be provided with the lining groove on the plate therein, this lining groove is fastenedly connected by side plate, lining trough floor and wing plate and forms, and its vallecular cavity is scraper plate cochain road, and side, the end face of lining groove centering plate and ledge all play a protective role long service life.The angle of intermediate channel ledge inner face and middle plate plate face is not less than 90 degree, and the lining groove can be packed into or takes out from notch, and serves as a contrast groove and ledge clamping; When the lining groove damages, can it be taken off from the notch top and change again and install, need not to open the intermediate channel attaching parts, time saving and energy saving, easy to maintenance quick, can increase substantially work efficiency, reduce mining costs.The lining groove can adopt the good material of wear resisting property separately as the consumable accessory of intermediate channel, also helps reducing production costs and use cost.
