Abstract
A wear resistant median plate of a middle cutting for a scraper conveyor comprises a reverse Y-shaped, square, X-shaped, or the like shape mechanism built-up welded by a wear resistant welding stick and a median plate not built-up welded. A plurality of wear resistant grinding blocks is built-up welded on the surface of the reverse Y-shaped, square, X-shaped, or the like shape mechanism built-up welded and a median plate not built-up welded along a scraper chain and through the gap of portions, the wear resistant grinding block can improve efficiently the resistance of the portion passed through by the scraper chain of the median plate of the middle cutting and decrease the abrasion of median plate caused by the scraper, thereby improving service life of the median plate. The utility model is suitable for the median plate of the middle cutting or the transition groove in the scraper conveyor, and has the advantages of simple structure, lower costing, and better effect of wear resistance, and widen prospect.
Description
Technical field
The utility model relates to the wear-resisting middle plate of The middle pan of scraper conveyor, is particularly useful for the middle plate of down-hole, mine The middle pan of scraper conveyor, transitional slot.
Background technology
Sheet material matter is the 16Mn steel plate mostly in China's The middle pan of scraper conveyor, and this steel plate has weldability preferably, but resistance to abrasion, corrosion stability are poor.Using more intermediate channel model at present has: SGZ730/400 type, SG2630/320 type, SGB764/400 type, SGB630/150C type, SGD630/220 type, SZZ630/90,40T type, 40 remodeling, 22 types etc.Because the ature of coal hardness difference in each ore deposit, the degree of wear of centering plate is also different, its mea life is 60～800,000 tons and crosses the coal amount, the annual intermediate channel of damaging because of wearing and tearing of China surpasses 400,000 joints, only the accessory loss just reaches 2～300,000,000 Renminbi, not only strengthened the loss of equipment, and influence is produced.
How to improve the resistance to abrasion of intermediate channel, be the problem that each coal production state all is concerned about very much, and dropped into great amount of manpower and material resources research.Current, the measure that developed countries is taked is: adopt resistance to abrasion, alloy steel that corrosion stability is good, even stainless steel makes intermediate channel, and widen plate in the thickening.Because the equipment investment of China is limited, can not adopt expensive high alloy intermediate channel.Therefore want to improve intermediate channel resistance to abrasion, increased the coal amount, can only be under the situation of material that does not change present intermediate channel and manufacturing process, in making strengthened in the plate surface.The method on plate surface has multiple in strengthening at present, but all be on the material of middle slab integral structure, to make an issue of, though can play a role, but its cost height, and because the restriction of colliery conditions down-hole, intermediate channel is difficult for keeping abswolute level putting of down-hole, cause the degree of tightness of chain inconsistent, thereby cause scraper plate chain bar and middle plate to mill, position, plate chain road severe wear in making, stressed back distortion and scrapping.
Summary of the invention
Technical matters: the purpose of this utility model provides the wear-resisting middle plate of a kind of simple in structure, cheap, effective The middle pan of scraper conveyor.
Technical scheme: plate during the utility model The middle pan of scraper conveyor is wear-resisting, it comprises the chevron pointing, gridiron of wear resistance electrode built-up welding, tiltedly lattice shape, strip shape, wavy shaped configuration and the middle plate of built-up welding not, described built-up welding have chevron pointing, gridiron, tiltedly lattice shape, strip shape, wavy shaped configuration and not built-up welding middle plate surface, along flight chain through the position at interval built-up welding a plurality of wear-resisting alloy blocks are arranged.
Plate during the utility model The middle pan of scraper conveyor is wear-resisting, the wear-resisting alloy block of described built-up welding can be square, bar shaped or circular; Square and the circular wear-resisting alloy block of described built-up welding along the two ends of flight chain trend for middle plate seamlessly transit domatic.
Technique effect: plate during the utility model The middle pan of scraper conveyor is wear-resisting is particularly useful for the middle plate of down-hole, mine The middle pan of scraper conveyor, transitional slot.In not changing former intermediate channel on the basis of sheet material matter and manufacturing process, the abrasion resistant alloy of flight chain trend, interval built-up welding definite shape, size, size is pressed in employing at middle plate middle part, it can improve in the intermediate channel plate flight chain effectively through the resistance to abrasion at position, reduce the wearing and tearing of scraper plate centering plate, thereby the service life of plate in improving effectively, it is simple in structure, cost is low, and is wear-resisting effective, has practicality widely.

Fig. 1 is the utility model embodiment one figure.
Fig. 2 is the utility model embodiment two figure.
Fig. 3 is the utility model embodiment three figure.
Fig. 4 is the utility model embodiment four figure.
Among the figure: plate among the 1-, 2-alloy block.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
Plate during the utility model The middle pan of scraper conveyor is wear-resisting, the a plurality of wear-resisting alloy blocks of built-up welding are at interval arranged in original built-up welding on middle plate 1 surface of chevron pointing, gridiron, tiltedly lattice shape, strip shape, wavy shaped configuration and not built-up welding, the material of wear-resisting alloy block can be Cr, W, Ti alloy, also can be Cr, Mn, Ti alloy or Cr, W, B alloy.Surfacing part is the position of plate in the flight chain process, when flight chain is strand, moves towards abrasion resistant alloy of built-up welding at interval along flight chain; When scraper chain is two, move towards one or two wear-resisting alloy blocks 2 of built-up welding at interval along flight chain.The wear-resisting alloy block of built-up welding can be square, and Fig. 1 is shown in Figure 3; Circular, shown in Figure 2; Bar shaped, shown in Figure 4.The wear-resisting alloy block 2 of square, circle or bar shaped built-up welding along the two ends of flight chain trend for middle plate seamlessly transit domatic.
