Description
Technical field
The present invention relates to counterbalance weight of engineering machinery
Background technique
Engineering machinery fork truck, excavator, loader, road roller, rotary drill pile driver, hoist, elevator base, lathe base, heavy mechanical equipment lathe bed, base, etc. engineering machinery need to adopt the weight of balancer weight, guarantee performance and the effect of stable operation.
The conventional cast forming technique that above-mentioned balancer weight is used, adopts pig and Iron And Steel Scrap, uses coal and coke melting, and the ironcasting balancer weight that Molding Casting forms consumes iron and steel resource and the consumption energy, befouling environment, cost of production is high in a large number.
The steel plate structure technology that above-mentioned balancer weight is used, adopts steel plate punched moulding to be welded into casing.The tank surface out-of-flatness of welding, manufactures fillet curve, concavo-convex word difficulty, increases cost of production.
Prior art model utility (CN2892812Y) discloses a kind of box type adjustable balancing weight steel plate installed-welded and has become case structure, insert reserved 30% packing space of iron sand for accepting or rejecting iron sand, adopt the splicing of steel plate hand cut, electric welding is polished into the manufacture method of casing, exist manufacturing efficiency low, the quality problems that the container body of steel plate that bumps exists depression weld cracking iron sand to flow out, operation turning road surface skew back crank produces and rocks, iron sand is predominate toward reserved 30% packing space, exist iron sand in rollover casing to go out, the safety technique quality problems that filler lid comes off.
Prior art invention (CN1718945A) discloses a kind of glass fibre reinforced plastics metalwork counterweight, production method adopts manual shearing to paste glass fiber cloth, there is the problem that manufacturing efficiency is low in brushing resin, there are the damaged and firm low quality problems of intensity in collision glass fibre reinforced plastics casing, glass fibre reinforced plastics casing is inserted balance weight body steel bar framework concrete, has the technical quality problems that product hoisting function is low.
Prior art invention (CN101077753A) discloses a kind of elvator counterbalancing blocks, and skin is steel structure housing, is connected with muscle 12,13 and inserts concrete between housing inner side.Employing steel plate cuts the housing being welded into and welds and be connected with muscle in housing, has the technical quality problems that manufacturing efficiency is low.
Adopt in housing steel plate materials to be connected with muscle thickness same, do not possess the technical characteristics of being inverted trapezoidal strengthened connection bar, the shrinkage that concrete generation is inserted in existence separates formation gap with steel plate housing, exist elevator to teetertotter and produce sound noise, vibrations collision produces the technical quality problems of shelling depression.
Prior art model utility (CN2853465Y) discloses a kind of wheel type tractor cast iron counterweight housing, adopt the firm intensity difference of gray cast iron material fragility, the open technical characteristics of counterweight housing (seeing Fig. 1), insert counter weight filler cement and resin, the shrinkage producing separates with housing and forms gap, and existence collision vibrations mass deviates from light specific gravity and hoisting function is low and the high technical quality problems of cost of production.
Prior art invention (CN1800071A), a kind of non-metal counterweight technology is disclosed, adopt discarded gold mine stone flour to be aided with chemical adhesive, curing agent, obtain through mold heated pressurization and water cooling, also can be in goods outer cup the production method with glass fibre reinforced plastics clothing, adopt discarded gold ore powder material fragility and proportion 8.0 than iron and steel weight, the material of gold content height and chemical adhesive and curing agent, there is the technical quality problems that firm intensity difference and cost of production are high, in goods outer cup with glass fibre reinforced plastics clothing, there is rough surface and be uneven technical quality problems whole and change product size and the hard thing breakage of collision iron and steel.
Summary of the invention:
The materials and methods of the present invention to prior art production counterweight, adopt not identical production materials and methods, the counterbalance weight of engineering machinery of manufacturing, reduce the consumption of iron and steel resource and the energy, save production cost, reach the effect of ironcasting counterweight, solve the collision of structural part of steel plate counterweight ghost and produce the mass defect caving in, there is the effect of improving the quality of products than glass fibre reinforced plastics metal reinforcement counterweight.
For achieving the above object, to adopting foundry engieering, the ironcasting counterweight of producing, the large Heavy Weight of volume, wall thickness are solid, and reform manufactures ironcasting or the Cast Steel of hollow thin-wall or part hollow thin-wall, have the casing that uses the various different trades mark and material, feeding port is set, insert the materials such as counterweight material, using closing cap is steel plate or cast iron, becomes ironcasting or Cast Steel counterbalance weight of engineering machinery.
The ironcasting code name that the present invention uses: " QT ", " KTH ", " KTB " material, balancer weight casing and the Cast Steel balancer weight casing manufactured, fill up on traditional foundry engieering, never used this material, the blank of manufacturing technology balance of machinery loaded van body, this material has higher toughness and intensity, insert the balancer weight that counterweight material is manufactured, more firm than prior art ironcasting counterweight qualitatively, do not exist prior art ironcasting counterweight to use ironcasting code name " HT " material fragility, clash into the easily mass defect of fracture, insert counterweight material and there is the technical effect saving production cost in a large number.
Counterbalance weight of engineering machinery casing of the present invention has ironcasting or Cast Steel, and the setting of feeding port, in the different position of balancer weight casing, is filled into the effect object in balancer weight casing for materials such as the needed counterweight material of balancer weight.
Cement and metal or non-metallic ore and ore in sand form for counterweight material in balancer weight casing, cost of production is low.
Counterweight material can or add yellow sand or pig or Iron And Steel Scrap or iron powder or iron sand or Manufacture Of Iron And Steel By Melting clinker or ground-slag with cement and non-metallic ore and ore in sand form, be combined into counterweight material according to different requirements, to reach required vary in weight, meet the technical requirements of counterbalance weight of engineering machinery.
The material different according to balancer weight casing, to determine whether to arrange hardware be bar construction or add metalwork or add steel pipe or add steel plate, reaches the object that increases balancer weight casing intensity.
On the loam core of ironcasting or the casting of Cast Steel balancer weight casing, the taper contiguous block that forms of casting that differs in size is evenly set, on the loam core of casting, be cast as and be inverted trapezoid shaped strengthened connection bar, reach with counterweight material and connect and compose one, strengthen casing and balancer weight intensity, improve the quality of balancer weight.
Paste all size at the balancer weight cabinet wall of unlike material and be made into glass fibre reinforced plastics contiguous block, the Iron And Steel Scrap contiguous block that welding or various flood cut into, reaches counterweight material and is connected and does not have gap ghost with balancer weight casing, increases balancer weight casing intensity and quality.
According to the technical requirements of unlike material, balancer weight casing uses segment glass steel part, saves production cost, and reaches and increases casing wall thickness toughness and intensity at cabinet wall sticking glass steel, improves balancer weight quality.
According to balancer weight casing and the technical requirements of unlike material, can not use closing cap, save production cost.
