Description
Technical field
The invention belongs to the apparatus for hoisting technical field, a kind of special hanger of hot metal charging in traveling crane band insulation cover particularly is provided.
Background technology
Molten iron has ground and aerial dual mode from blast furnace discharge yard to the transfer transportation that is blended in converter or the electric furnace at present; Terrain transportation by locomotive, automobile or the Transport Desk of special use vehicle-mounted hot-metal bottle or the torpedo jar of inner lining refractory realize; Air transport occurs in the steelworks hot metal charging basically and strides, by metallurgical crane handling hot metal charging bag.Rapid popularization along with the Molten Iron Pretreatment technology; Ladle one bag notion is on earth strengthened; This life-span to ladle has proposed more exacting requirements; And the anti-material loss of traditional uncovered hot-metal bottle and ladle is big, maintenance is frequent, the life-span is very short, is to prolong the most direct effective and efficient manner of its life-span through keeping hot-metal bottle and ladle whole process that lid is arranged, and therefore can practices thrift a large amount of energy.
In the terrain transportation mode, torpedo tank car has solved the problem of hot metal temperature drop on the structure well, implements to add a cover fairly simple to the less oral area of torpedo jar; And adopt special locomotive, automobile or transport and adopt my company's invention when chassis transports hot-metal bottle, ladle " a kind of hot-metal bottle combined cover and uncovery method thereof ", successfully solved the difficult problem of adding a cover of hot-metal bottle.
Steelworks is striden at hot metal charging and is adopted metallurgical driving handling hot metal charging bag and implement to convert the iron operation.Ladle for bucket formula structure; Traditional management mode is not add a cover, traditional concepts also be the words of adding a cover convert the iron operation can not be normal because the integral cap that is just understanding is annotated the iron of falling the initial stage at molten iron; Water can wash away the inboard refractory material of lid in the bag; Molten iron stream also mouthful makes liquid level spread into waterfall shape because of the deadweight of lid is fitted in bag, so not only strengthens the area of molten iron stream radiation and convection current, the thermal loss increasing; And cause the also difficulty increasing of overhead traveling crane positioning seat, and also have overall lid when ladle is overturn, to be difficult for fixing problem.But good again scheduling, the uncovered ladle accounts for total thermal loss about 50% around here through the thermal loss that its upper oral part radiation and convection current cause.And for the high temperature slack tank, in initial 8-10 minute of its slack tank, thermal loss is maximum, is about 1/3 of aforementioned loss amount approximately, and ladle is still on the overhead traveling crane suspension hook around here.The utility model " hot metal charging in traveling crane band insulation cover special hanger " replenishes as what ladle whole process was added a cover, can solve the add a cover problem of ladle on the overhead traveling crane suspension hook time well.
Summary of the invention
The object of the present invention is to provide a kind of special hanger of hot metal charging in traveling crane band insulation cover; Do not changing original production sequence of events and do not increasing under operator's the situation; Realize that ladle is in the operation of adding a cover of driving a vehicle in transit; And guarantee that this covers and when converting the iron operation, can in time rationally dodge molten iron stream and slag stream, convert the iron operation accomplish this lid of back in good time lid in fact, lost to control heat to greatest extent.
The present invention can replace the special-purpose sight rail hook of former metallurgy, also can form through transforming the special-purpose sight rail hook of former metallurgy.
The present invention includes hinge means, electric control system on a shape connecting traverse assembly, composite thermal insulation lid, insulation cover jacking system, insulation cover folding (or folding) and lock hanging system, the ladle.Insulation cover is connected through hinge means with ladle.The insulation cover jacking system is directly installed on the shape connecting traverse assembly, moves with connecting traverse, and the lock hanging system is connected with hinge means.
Insulation cover folding before and after being fit to folds and the lock hanging system; The jackknife action of insulation cover is that electronic cylinder drives piston crank mechanism when releasing and accomplishes; Gear on the oscillating axle drives the lock hanging bearing pin simultaneously and moves and lean on the hinge means of jail on the ladle; Insulation cover was flat when electronic cylinder reeled opens, and the lock hanging bearing pin is automatically away from hinge means, so that the insulation cover jacking system is accomplished the lift work of insulation cover; Be fit to the insulation cover open-close system 4 (referring to Fig. 4) of opening and closing left and right, the opening and closing movement of insulation cover is electronic cylinder direct drive, about jointed shaft and the guide rail of lid through vertical rotation link together.
Independently electric control system satisfies exclusive technological requirement, and the main equipment driving is responsible for also accepting useful signal mutually to this special use electric control system power supply, with the sequence control linkage relationship necessary to each other with maintenance of accomplishing each action of suspender.
The invention has the advantages that; Do not increase under operator's the situation; Do not influencing under the unobstructed situation of original logistics; Adopt that mechanism is simple, reliable in action, operate steadily and continuity is good, degree of automation is high special hanger, accomplish uncovery operation via air transport equipment transhipment ladle; And guarantee that this covers and when converting the iron operation, can in time rationally dodge molten iron stream and slag stream, this suspender especially is fit to the existing travelling crane suspender is transformed, and realization is incubated, guarantees the quality or protects the purpose of environment with getting twice the result with half the effort.
Enforcement of the present invention will urge steel mill to carry out few quantity of slag or clean slag operation, can under driving ability unmodified situation, still can keep the requirement of steel mill about the molten iron transport capacity like this.
