Description
One, affiliated technical field
The utility model relates to a kind of industrial lifting, transportation device, especially relates to bucket case of light-duty high life of a kind of composite structure.
Two, background technology
The bucket case is the vitals that constitutes lifting, transportation device, is made up of jointly bucket case, main body load parts-support body and other accessory as liftings such as vertical shaft skip, inclined shaft skip and mine car, shipping products.At present, known steel bucket case adopts high-quality low carbon-structural steel, low-carbon alloy structural steel (16Mn) to make, (" a kind of be used for mine thing promotes light-duty " skip bucket patent No.: upper box body 87213675) adopts high-strength aluminum alloy material to known light-duty skip bucket, and lower part box adopts the high-quality alloy steel manufacturing.
In mining industry and other similar industrial environment, bucket case working environment high humidity, often with the trickle phenomenon, because each mine water quality potential of hydrogen difference, the bucket case that metallic material is made is subjected to chemical corrosion and electrochemical corrosion in various degree, steel and aluminum alloy all can not actv. the chemical corrosion and the electrochemical corrosion of opposing working environment, aluminum alloy materials is at steel aluminium binding site, because the material electrode potential differs greatly, the electrochemical corrosion phenomenon is especially serious.
The bucket case stands to load and unload fast the impact and the wearing and tearing of material, and under the combined action of normal wear and corrosion wear, the casing wearing and tearing are very fast, especially lower part box, under the effect that material impacts, quick abrasion, distortion is serious, and the lower part box life-span is about a year and a half, far below upper box body and support body, make the casing maintenance cycle short, maintenance load is big, under the situation that damaging does not appear in support body, and box deformation, serious wear, cause scrapping of integral transportation, lifting means, product life is short.
When adopting steel as the wallboard of bucket box body, because the steel corrosion stability is poor, the sticking coal of bucket tank wall is serious, has increased the weight of lifting process hollow skip bucket, has reduced load carrying ability.
Tradition promotes, the bucket case of transportation device is low owing to institute's materials used strength-to-density ratio, and equipment integral weight is big, causes clean lifting or domestic shipping weight to reduce, and production efficiency is low, and energy resource consumption is big.
Three, summary of the invention
In order to overcome existing bucket case product corrosion-resistant in working environment, wear resisting property is low, maintenance load is big, time between overhauls is short, from great, the shortcoming that lifting weight is little, production efficiency is low and product life is short, the utility model provides bucket case of light-duty high life of a kind of composite structure, bucket case decay resistance height of light-duty high life of this composite structure, and wear resisting property is strong, easy to maintenance quick, maintenance load is little, and time between overhauls is long, and it is little to conduct oneself with dignity, the lifting domestic shipping weight is big, and capacity rating is high and product life is long.
The technical scheme that its technical matters that solves the utility model adopts is:
Bucket case of light-duty high life of the utility model composite structure, it comprises upper box body, lower part box, fan-shaped gate.The wallboard of upper box body adopts composite structure, abrasion-proof backing block is equipped with in high strength steel skeleton inboard, the outside is coated with fiber-reinforced resin material shell (preferred flame retardant glass fiber reinforced plastic), the high strength steel skeleton, abrasion-proof backing block adopts riveted joint to be connected with the bolted connection method with fiber-reinforced resin material shell, be provided with criss-cross or the sandwich material of M shape at the neutral gear place of high strength steel skeleton, sandwich material is positioned in the middle of abrasion-proof backing block and the fiber-reinforced resin material shell, abrasion-proof backing block, the high strength steel skeleton, sandwich material and fiber-reinforced resin material shell are in contact with one another surface glue and are connected into one.Known technology is adopted in other structures and method of attachment.Consult the patent No.: 87213675 " a kind of light-duty skip buckets that are used for the mine thing lifting ".
Sandwich material, fiber-reinforced resin material shell and abrasion-proof backing block have formed the sandwich structure reinforced rib, and sandwich structure effectively improves the rigidity of part, alleviate the weight of part and product.Sandwich material can adopt aluminium, timber and rigid poly urethanes expanded material etc., the rigid poly urethanes expanded material that preferred specific gravity is light according to the difference of designing requirement.
Because the high corrosion stability of fiber-reinforced resin material, can guard box body high strength skeleton and antifriction metal (AFM) liner plate, isolated chemical corrosion and electrochemical corrosion, thereby the life-span of improving product.
Use high strength alloy steel to make the strength and stiffness that the high strength steel skeleton strengthens casing, can effectively resist casing distortion in use.
Upper box body is installed on the main body load framework, adopts rivet or bolted connection method and links to each other with the load framework.Riveted joint and bolted connection have sealant to isolate in conjunction with face and steel aluminium faying face, take place with isolated electrochemical corrosion.
Abrasion-proof backing block adopts superstrength alloy aluminium sheet, high tensile steel plate or carbon structural steel plate spraying of wearable coating etc. according to the actual requirements, because aluminium sheet possesses higher corrosion stability, and the rare sticking coal phenomenon in surface, preferred ultrahigh-strength aluminum alloy material is as abrasion-proof backing block.
The composite structure casing is made in the forming process, and side plate, high strength steel skeleton, sandwich material and the splicing of fiber-reinforced resin material shell are integral structure component in it, have improved the load-carrying capacity of casing, have alleviated pts wt.
When loaded material, the lower part box of the position that casing is hit such as the lower part box of vertical shaft skip, inclined shaft skip, mine car lower part box, the use high strength steel is made, the steel plate that contacts with material uses high-strength abrasion-proof steel NM360 material to make, actv. has alleviated lower part box and has been loaded the distortion that impact causes, improve friction durability, make entire product can reach long-life requirement.
The casing fan-shaped gate is a part that constitutes the bucket case, is subjected to the impact of loaded material equally, and is yielding, and quick abrasion, the arc door-plate of fan-shaped gate are impacted by material directly and friction, adopts high-strength abrasion-proof steel NM360 to make, and effectively reduces distortion, increases product life.
Under the not serious situation of chemical corrosion and electrochemical corrosion, can still can reach each parts balanced life of product, the requirement of high life without composite fiber-reinforced resin material shell for reducing cost of product.
The beneficial effects of the utility model are: can tolerate the corrosion attack of harsh environment, and the resistance to abrasion height, maintenance load is little, and is easy to maintenance, and time between overhauls is long, and product is from heavy and light, promotes, transportation volume is big, the production efficiency height, product life is long, and energy-saving effect is obvious.
