Description
Technical field
The present invention relates to crane field, particularly Ultrahigh-lift crane trolley.
Background technology
Along with metallurgical and other all kinds of heavy-duty machinery keep the large-scale development and the improvement of traditional handicraft, the requirement of Ultrahigh-lift crane is increasing.But the suspender of Ultrahigh-lift crane adopts lifting hook pulley group canoe usually at present, and the length of steel wire is longer, and the length of steel wire is at least twice lift.Suspender only has an equalizing bar, the two ends of equalizing bar are respectively provided with a movable pulley, when Ultrahigh-lift crane is in decline process, relative to high-lift, distance between the steel rope of movable pulley both sides almost can be ignored, and can regard coincidence as point-blank, so the steel rope of movable pulley both sides is easy to the knotting that twists by approximate for two sections of steel ropes, steel rope is easily loose by stone roller after passing through pulley, and then loose voluntarily.Therefore there is following shortcoming in existing Ultrahigh-lift crane: reel dimensional structure is large, drift angle of restricting under steel rope is large, there is steel rope twist ties, loose voluntarily because twisting around power release in steel rope, four suspension centres occur asynchrony phenomenon in decline process in ultrahigh pump lift.Therefore, existing Ultrahigh-lift crane affects the normal use of lifting mechanism to a certain extent, cannot meet the requirement of ultrahigh pump lift (H=370m) weight-lifting equipment.
Current conventional hoist lifting mechanism is arranged as reel-reductor (parallel shafts)-drg-electrical motor, and steel rope realizes different multiplying by running block, fixed pulley group.It is very large that large lifting altitude (lift) and a large liter weight determine the wirerope-winding amount be wound on hoisting drum, when adopting traditional screw type reel multilaminate coiled, it is more than the second layer and the second layer that each layer steel rope can produce disorder cable phenomenon in winding process, and serious wear between rope, reduce the service life of steel rope, and also need to increase rope guide, there is complex structure in rope guide, lead inflexible defect, easily causes stuck phenomenon.Ultrahigh-lift crane uses tradition to hoist and arranges that drawback is rope capacity long (lifting altitude takes advantage of multiplying power number), cause drum diameter super large and length overlength.Reductor has to strengthen width between centers due to the restriction of drum diameter, causes reductor cost to increase.Reel length is long, and steel rope lifting process deflection angle is excessive easily causes steel rope disorder cable.
Two winding drum lifting mechanism is the method that the problem solving Ultrahigh-lift crane reel wiring is commonly used.At present, adopt the method that two reel is wound around, be divided into open type and enclosed two type, shown in Fig. 1 and Fig. 2 in " the wiring problem of Ultrahigh-lift crane " paper as interim in Chinese periodical " hoisting crane machinery " 1988 07 respectively, two reel winding does not add change to original total rope system multiplying power, just share the load of an original reel by two reels and to restrict be that multiplying power reduces half, thus lifting altitude can double.But, the two winding drum lifting mechanism arrangement structure of open type as shown in this paper Fig. 1 is that the two reels be arranged in parallel are connected with same retarder by gear transmission, the pivot center of retarder is parallel with the pivot center of two reel, electrical motor is connected with retarder by drg, motor reel and drum shaft are arranged in parallel, and the shared volume of this lifting mechanism arrangement structure is larger; Closed-type double action crank press winding drum lifting mechanism arrangement structure as shown in Fig. 2 in paper is that two reel be arranged in parallel, motor reel is set in parallel between two winding drum, the two ends of electrical motor are respectively distributed with one for its pivot center connected with corresponding reel retarder parallel with the pivot center of reel, this closed-type double action crank press winding drum lifting mechanism arrangement structure is not compact, two retarders are needed to realize transmission, complex structure.
Summary of the invention
