Description
Technical field
The utility model relates to metal casting fused mass field of containers, is specially a kind of hydraulic lift that is used for the ladle uncovery.
Background technology
Often need utilize ladle transhipment molten steel in the process of steel-making, during transhipment, ladle also plays insulation to ladle except that the container as molten steel.For reduce the in transit thermal loss of molten steel as far as possible, ladle can be equipped with top cover and add corresponding uncovery device.Ladle uncovery device has cantilevered and telescopic two kinds, and cantilevered adopts positioning of rotating, and setting accuracy is not enough, and complicated operation when at every turn implementing the uncovery operation is consuming time longer.Telescopic bulky, be not suitable for the narrow and small smeltery of working space, ladle can't use top cover like this, the temperature loss when causing the molten steel transhipment.Smelting with the LF refining furnace is example, takies to practice thrift investment for reducing the place, and the LF refining furnace adopts the cross layout more; The traffic direction that is ladle is perpendicular to converter, and this layout can't adopt telescopic uncovery device, and when using cantilevered uncovery device; Because positioning accuracy is poor; Before uncovery, must stop the operation of ladle earlier, reduced production efficiency, and the equipment installation difficulty be big.
The utility model content
In order to overcome the defective of prior art, a kind of compact conformation, advantages of small volume, easy for installation, accurate, the adaptable ladle auxiliary device in location are provided, the utility model discloses a kind of hydraulic lift that is used for the ladle uncovery.
The utility model reaches goal of the invention through following technical scheme:
A kind of hydraulic lift that is used for the ladle uncovery comprises underframe and suspension hook, and suspension hook is fixed on the below of underframe through bearing pin; It is characterized in that: also comprise upper frame, go up fixed bar, up-down joint, base and hydraulic cylinder; The upper fixed of underframe goes up and down to save, the upper fixed upper frame and the last fixed bar of the joint that goes up and down, a side firm banking of a frame of upper frame; Fixer cylinder pressure on the base, the opposite side frame of the piston rod of hydraulic cylinder and upper frame firm banking frame is fixed.The joint that goes up and down is made up of elevating lever, connecting rod and bearing pin, and elevating lever and connecting rod respectively have four, and bearing pin has ten; Per two elevating levers are connected to become one group with mid point through a bearing pin; Underframe is connected through two groups of elevating levers with upper frame, connects through four connecting rods between two groups of elevating levers, and every group of elevating lever connects a frame of underframe and a frame of upper frame respectively; In every group of elevating lever; The lower end of two elevating levers is fixed on two relative frames of underframe through bearing pin respectively, and the upper end of an elevating lever is fixed on an end of fixed bar through bearing pin, and the upper end of another root connecting rod is fixed on the frame of upper frame through bearing pin.
The described hydraulic lift that is used for the ladle uncovery is characterized in that: it is the end to end rectangle that pieces together of channel-section steel of " worker " font that underframe and upper frame all use the cross section, and it is the channel-section steel of " worker " font that last fixed bar adopts the cross section, and hydraulic cylinder is selected oil cylinder for use.
When the utility model used, erection truss on the course of ladle was fixed on the truss bottom with the upper frame and the last fixed bar of the utility model, thereby the utility model is fixed under the truss.During no operatton, the piston rod of hydraulic cylinder stretches forward, and the joint that goes up and down shrinks.When the ladle of band top cover marches to the utility model below, stop, the piston rod of hydraulic cylinder is to after-contraction, and the joint that goes up and down opens; Because upper frame and last fixed bar all are fixed on the truss, so the underframe band suspension hook and descends together, catches on the hanger of ladle top cover in the decline rear hanger swing that puts in place; The piston rod of hydraulic cylinder promotion subsequently stretches forward, and the joint that goes up and down upwards shrinks, and suspension hook promotes top cover like this; Completion is taken off and is covered operation, and top cover promptly hangs on the suspension hook.Add a cover operation and take off that to cover operation opposite, when half-headed ladle marches to the utility model below, stop, the piston rod of hydraulic cylinder is to after-contraction; The joint that goes up and down opens, and suspension hook by the underframe band and top cover descends together, colludes the hinge of ladle at the decline back header that puts in place; The piston rod of hydraulic cylinder promotion subsequently stretches forward; The joint that goes up and down upwards shrinks, and top cover is stayed on the ladle, accomplishes and adds a cover operation.
Ladle uncovery when the utility model has realized that steel mill molten steel treating apparatus and ladle orbit are the cross layout, add for ladle top cover application extension new application, be particularly useful for the LF refining furnace and smelt.The utility model applied in reverse hydraulic pressure scissors fork lowering or hoisting gear; Scissors is pitched lowering or hoisting gear to be applied among the operating mode of lower platform motion; Utilize guidance quality, the mass motion property of hydraulic pressure scissors fork and horizontal movement is converted into the characteristic that moves both vertically and realize steadily going up and down, potential safety hazard such as do not lay particular stress on, topple.The swing of suspension hook design reduces the positioning requirements of suspension hook when the hook top cover greatly, when suspension hook is arranged and top cover throw off fully, do not interfere the operation of ladle.The present invention takes up room less, can in arranging compact steelshop, use the uncovery device, and implement ladle whole process and add a cover, thus energy efficiency.Temperature drop in the molten steel transportation is changed slowly, and more because ladle finishes when receiving steel once more in casting, it is above (according to measuring and calculating that the temperature of inner cylinder-packing still can remain on higher temperature; The ladle that does not add top cover; Even through online baking, the cylinder-packing temperature can only arrive 800 ℃～1000 ℃), this has just reduced the temperature requirement to converter tapping; The converter tapping temperature can reduce by 8 ℃～15 ℃; Can reduce process cost and process energy consumption greatly during smelting, make steel 1,000,000 tons of meters per year, can save about 1,000 ten thousand～1,400 ten thousand yuan every year.The beneficial effect of the utility model is: simple in structure, easy for installation, and processing ease, energy efficient, safe and reliable.
