Abstract
The invention relates to wear-resistant pattern surfacing welding of a middle groove transition groove of a scraper conveyor, which is characterized in that a layer of wear-resistant alloy is surfacing-welded on the surfaces of a middle plate of the middle groove and the transition groove by using a wear-resistant surfacing welding rod according to a certain pattern and size on the basis of not changing the material and the manufacturing process of the middle groove transition groove, so that a scraper and a chain slide on a welding seam and are separated from contact with a matrix of the middle plate, the middle plate is fundamentally protected, and the service life of the middle groove and the transition groove is greatly prolonged.
Description
The present invention relates to wear resistant pattern build-up welding, particularly on the middle plate surface of The middle pan of scraper conveyor lead-over groove, carry out wear resistant pattern build-up welding.
Continuous development along with coal industry, the raising of comprehensive mechanical coal mining level, the output of drag conveyor constantly increases, requirement to service life of The middle pan of scraper conveyor lead-over groove is also more and more higher, from the present intermediate channel consumption of China, the intermediate channel of the annual wear out failure in the whole nation reaches more than 400,000 joints, and only the accessory loss is 2～300,000,000 yuans, and it crosses the coal amount below 1,000,000 tons; The transition chute is shorter service life, and the service life in most of mining areas is all low, crosses the coal amount and has only 15～300,000 tons.For improving the wearability of drag conveyor, generally adopted at chain road, intermediate channel termination place's built-up welding two antifriction alloy powder agglomates, reduce the wearing and tearing of scraper plate centering plate, but the built-up welding piece forms a boss in middle plate termination, scraper plate by the time produce collision, beat, not only increased resistance to scraper plate, also aggravated the wearing and tearing of scraper plate, in case the scraper plate bottom surface grinds after the twice deep trouth, scraper plate in the same old way can be with middle plate wearing and tearing.
The purpose of this invention is to provide a kind of The middle pan of scraper conveyor lead-over groove large tracts of land pattern build-up welding, it can improve the wearability of intermediate channel lead-over groove effectively.
The object of the present invention is achieved like this, on material that does not change intermediate channel lead-over groove itself and manufacturing process basis, with hardfacing electrode by certain style, size built-up welding one deck antifriction alloy on the plate surface in intermediate channel and lead-over groove.The built-up welding style can be lambdoid, also can be checkering, oblique form, long strip type and awave.
The present invention because only need be in the The middle pan of scraper conveyor lead-over groove built-up welding one deck antifriction alloy on the plate surface; so method is simple especially; thermal deformation during for the minimizing built-up welding; and reduce the built-up welding cost as far as possible; adopted various pattern build-up welding; make scraper plate and chain slide in welded joints like this; disengage with middle plate parent; fundamentally the centering plate is protected; thereby increased substantially the service life of intermediate channel and lead-over groove; through down-hole industrialness contrast test, effect is remarkable, has improved service life more than 3 times.

Below in conjunction with accompanying drawing embodiments of the invention are further described:
The middle pan of scraper conveyor wear resistant pattern build-up welding of the present invention, its conveyer intermediate channel is all identical with the lead-over groove structure, all is welded by ledge 1 and middle plate 2, and different is that lead-over groove has radian.On material that does not change intermediate channel lead-over groove itself and manufacturing process basis, size on demand, figure line earlier, again with hardfacing electrode by drawn graphic pattern, size built-up welding one deck antifriction alloy 3 on the plate surface in intermediate channel, the alloy height is about 1.5mm, weld interval is about 100mm, weld width is about 10mm, about every long 100mm of weld seam.The style of build-up wear-resistant alloy 3 can be lambdoid as shown in drawings, also can be checkering, oblique form, long strip type and awave.For preventing post welding distortion; take conventional prestrain method; promptly before built-up welding, with two steel pipes ledge steel 1 upper edge is strutted 5mm earlier; after the built-up welding when the upper surface weld seam is cooled to below 100 ℃; play steel pipe again; ledge steel bead change in size is protected substantially within 1～3mm about the intermediate channel lead-over groove of built-up welding like this, can not influence the down-hole and install and use.Electric welding machine can be used DC welder, also available AC welding set, and when electrode size was 4mm, it was 140A that direct current is selected electric current for use, and exchanging and selecting electric current for use is 180A, and electric arc is 3～5mm.
Claims (2)
1, The middle pan of scraper conveyor lead-over groove wear resistant pattern build-up welding, it is characterized in that: on material that does not change intermediate channel lead-over groove itself and manufacturing process basis, with hardfacing electrode by certain style, size built-up welding one deck antifriction alloy on the plate surface in intermediate channel and lead-over groove.
2, The middle pan of scraper conveyor lead-over groove wear resistant pattern build-up welding according to claim 1, it is characterized in that: the style of built-up welding can be lambdoid on the middle plate surface, also can be checkering, oblique form, long strip type and awave.
