Abstract
The invention discloses a scraper conveyer middle groove with a ledge having a steel plate assembly welding structure. The scraper conveyer middle groove is formed by performing assembly welding on a shovel plate tip, reinforcing ribs, a shovel plate ledge, a guide plate, a middle plate, a bottom plate, a side plate, a large bending plate, a small bending plate, a coupling plate, a rail seat, a dumbbell pin connecting seat, a lower guide plate, an upper guide plate, a front upper flange, a rear upper flange, a rear bottom plate, a baffle ledge, a vertical rib plate, a pulling lug, a bottom rib plate and the like. After two sections of middle grooves are butted with each other, the two sections of middle grooves are positioned through a pin shaft, and the dumbbell pin connecting seats of the two sections of the middle grooves are coupled through a dumbbell assembly. The shovel plate ledge and the baffle ledge are formed by blanking and machining steel plates, and the steel plates can be selected from high-strength wear-resistant plates; and therefore, according to the assembly welding structure, the problem that the technical requirements of the rolling ledge are difficult to realize is solved, and the wear resistance of the middle groove ledge is improved.
Description
Technical field
The present invention relates to a kind of colliery load transfer device, particularly a kind of ledge is the middle pan of scraper conveyor of steel plate installed-welded structure.
Background technology
At present, just towards the development of the aspects such as large haul distance, large conveying quantity, heavy-duty, the slat conveyer of the series such as SGZ1400 that China is using mainly relies on import to scraper conveyor for coal mines.The intermediate channel of slat conveyer is very crucial parts, and its performance is directly connected to the key indexs such as the reliability of a whole set of conveyer, mistake coal amount.Intermediate channel shovel board ledge, baffle and upper flange that abroad should series be rolled structure, the advantage of this rolled structure is that the aspect performances such as work efficiency, stock utilization and intermediate channel reliability are higher, but it also exists, and the rolling mold expense is high, trial-produce period long, to rolling mill practice shortcoming and the limitation such as have relatively high expectations, therefore be difficult to be widely adopted.In order to make this serial slat conveyer can import substitutes, fill the domestic gaps, promote the development of coal in China industry, digesting and assimilating on the basis of advanced foreign technology, this serial intermediate channel is redesigned, shovel board ledge wherein, baffle and upper flange adopt the form of high-strength wearable plate assembly welding, newly-designed structure has not only avoided the rolled ledge die cost high, trial-produce period is long, the problems such as technological requirement height, and because the employing of high-strength wearable plate, resistance to abrasion and the reliability of intermediate channel have greatly been improved, for the smooth operation of slat conveyer provides the failure-free assurance.
Summary of the invention
The technical problem to be solved in the present invention is for the deficiencies in the prior art, has proposed a kind of manufacturability of simplifying the intermediate channel structure, and has improved the reliability of intermediate channel and the ledge of resistance to abrasion is the middle pan of scraper conveyor of steel plate installed-welded structure.
The technical problem to be solved in the present invention is achieved through the following technical solutions, a kind of ledge is the middle pan of scraper conveyor of steel plate installed-welded structure, be characterized in: comprise by base plate, middle plate, shovel board ledge and baffle assembly welding main frame together, baffle is welded on base plate rear end, the shovel board ledge is welded on base plate front middle part top, middle plate is welded between shovel board ledge and the baffle, at base plate, middle plate, consist of lower chain road between shovel board ledge and the baffle, the rear and front end of lower chain road tank top plate is welded with guide plate, upper flange before shovel board ledge welded top has, upper flange after the baffle welded top has, above middle plate by front upper flange, rear upper flange and shovel board ledge and baffle consist of the cochain road, be welded with respectively guide plate and lower guide plate in the top and bottom of middle plate rear and front end, be welded with the dumbbell pin Connection Block at the two ends, the left and right sides, the outside of shovel board ledge and baffle respectively, between the dumbbell pin Connection Block of the two ends, the left and right sides, the outside of shovel board ledge, be welded with some reinforced ribs, front end at base plate is welded with the shovel board point downwards, two ends, the left and right sides below base plate are welded with side plate, the front end of side plate and the welding of shovel board point, the rear end of side plate and baffle welding, between the base plate of floor below and shovel board point and be equipped with the bottom gusset between base plate and the baffle, base plate after the rear lower portion of baffle is welded with, top, rear at baffle is welded with large bent plate, rail chair is contained in large bent plate top, the upper end of large bent plate rearward is welded with gusset piece, between rear base plate and large bent plate, be welded with some vertical rib plate, in the middle of the rear of baffle, be welded with to draw and move ear, draw the top and bottom of moving ear to weld with large bent plate and rear base plate respectively.
The present invention compared with prior art adopts the assembly welding structure, after the two joint intermediate channel docking, by bearing pin two joint intermediate channel is positioned, and connects by the dumbbell pin Connection Block of component of dumb bells to two joint intermediate channel.Described shovel board ledge and baffle are the direct blanking of steel plate, process, and steel plate can be selected the high-strength wearable plate, and therefore, this assembly welding structure has not only avoided the rolled ledge manufacturability to require the problem that is difficult to realize, has improved again the resistance to abrasion of intermediate channel ledge.
