Description
Technical field
The present invention relates to a kind of operational method and device of hoisting crane, refer in particular to a kind of lifting method and device of ladle carne.
Background technology
Ladle carne is a type of crane in bridge type, is generally mainly used in steelshop and makes transportation molten steel, the Special Hoisting Equipment to molten iron and teeming.Its main carriage is mainly used in promoting steel ladle, requires safe reliability high.The main hoisting mechanism of current domestic large-scale foundry crane mainly contains following several form:
1, adopt single reductor pattern, two high speed axial region offices are in reductor inner side, and chain with middle part Jie's tooth, office of two winding drum portion is in reductor two ends form.
Its major defect has: in big retarding machine, any off-axis fault all can cause unpredictable accident, and safe reliability is relatively low; Whole reductor one two axles, three axle big gear wheels are consumable accessorys, the replacing that is difficult to roll off the production line of whole reductor, and site examining and repairing difficulty is large.
2, main lifting adopts three independent reductors (office of product word portion, gear coupling connects) and main carriage split pattern.
Its major defect has: transmission chain length, and easy break-down point, in three reductors, any off-axis fault all can cause unpredictable accident. and safe reliability is relatively low.
3, main lifting adopts the whole pattern of big retarding machine, two high speed axial region office's reductor two ends, and office of two winding drum portion is in reductor inner side and interlock with middle part Jie's tooth.
Its major defect has: main lifting big retarding machine entire length and main carriage are basic with long, over 10 meters, under load, trolley frame there will be flexible sex change, can make whole big retarding machine in each intracardiac distance change and affect tooth engagement, trolley frame need have enough rigidity, manufactures relative difficulty higher.And whole big retarding machine cannot roll off the production line and change maintenance.One two axles, three axle big gear wheels are consumable accessorys, uncap in scene, and maintenance is also inconvenient.
Therefore necessary main lifting method and mechanism to existing large-scale foundry crane improved.
Summary of the invention
The object of the invention is to overcome the main lifting method of existing large-scale foundry crane and the deficiency of mechanism, provide a kind of safety and reliability high, and processing technology simple, overhaul main lifting method and the mechanism of large-scale foundry crane easily.
For realizing goal of the invention of the present invention, the technical scheme providing is: a kind of ladle carne lifting method, by two three-point suspension-type reductors and middle part big retarding device, formed, adopt split type main lifting big retarding device, the two roll device liftings of Dual Drive, from electrical motor (actuating device) one end by high speed shaft coupler and drg (safety device), connect three-point suspension-type retarder, three-point suspension-type retarder connects middle part big retarding device by tooth axle, middle part big retarding device connects reel by low-speed shaft coupler again, realizes the lift heavy function of hoisting crane.Three-point suspension-type retarder is connected and fixed by adjusting king bolt, and carries out safety guard-safeguard by adjusting secondary bolt, and lifting mechanism safe reliability is further improved.
The jack up unit of the ladle carne proposing according to said method is: a kind of jack up unit of ladle carne, comprise electrical motor, and electrical motor is driven and is hung retarder by high-speed coupling; Underslung retarder is located by tooth axle and middle part big retarding device twin shaft platform, and Double-conical-surface clamps; Middle part big retarding device is connected with reel by slow-speed shaft, drum coupling; The other end of reel is bearing on reel supporting base.Trifilar suspension reductor belongs to without floor installation, conducts oneself with dignity relatively light, and the three-point suspension-type reductor quill shaft pillow block conical surface is two strong points, and the 3rd attachment point is that king bolt adjustment of the little cephalic par of reductor is fixed on support.Two secondary bolts of king bolt both sides design, normal secondary bolt in service place, without predetermincd tension state, guarantees reductor place supported at three point strained condition.When bursty state king bolt lost efficacy, two secondary bolts play safety guard-safeguard effect.Integral replacing three-point suspension-type reductor, three axle big gear wheels are with the hollow shaft sleeve of internal tooth, and axle sleeve compresses location by two conical surfaces respectively.
The present invention has six large features:
1. the transmission link before arbitrary reel occurs that off-axis fault can not cause serious accident, and main elevator system safe reliability is high;
2. middle part main gear reducer and suspension speed reducer belong to separate assembling, and in two meters of suspension speed reducer width between centerss, its inner teeth engagement is not affected by the elastic deformation of trolley frame under load.Middle part main gear reducer head center distance degree reduces by three meter of five left and right with respect to whole big retarding machine, has improved its stiffness reduction and has been subject to trolley frame deformation effect, can effectively improve the running precision of reductor.
3. reductor Split assembled structure, each split reductor width between centers effectively diminishes, and is convenient to manufacture respectively processing; Between each split reductor, figure mono-is shown in non-rigid connection, has reduced the rigidity requirement to trolley frame, has reduced the difficulty that trolley frame is manufactured.
4. whole big retarding machine one or two axles, three axle big gear wheels are consumable accessorys, are formed the convenient maintenance of independent whole reductor and change.
5. major-minor reductor shaft is connected with gear set, and secondary reductor is without base, and structure is lightly compact, and minimum takes up room.
6. major-minor reductor is set with the fastening end cap of connection, and the symmetrical conical surface transmitter shaft in two ends, to power, diametral load (open wedge harmomegathus nested structure), makes suspension speed reducer and main gear reducer axle determine position by automatic precision, fixes, and makes the interior external tooth driving torque of its axle steadily reliable.
The invention has the beneficial effects as follows: the present invention compared with prior art, by increasing three-point suspension-type retarder, can make lifting mechanism drive mechanism safe and reliable, easy to maintenance, manufacture craft is simple, and Ke Gei enterprise and country bring huge economic interests, and by middle part big retarding machine tooth axle and three-point suspension-type reductor quill shaft, twin shaft platform location, Double-conical-surface clamping structure, this has guaranteed suspension speed reducer accurate positioning, internal tooth is steady driving torque accurately.
