Description
Technical field
The present invention relates to a kind of bridge crane hoisting mechanism, particularly relate to the lifting mechanism of great type crane facility, belong to technical field of crane equipment.
Technical background
Along with the long-term needs of clean energy resource, domestic water power obtains and develops faster, and large quantities of large rubber good, appears in the continuous lifting of turbine-generator units design and manufacture ability.In large hydropower station project, the excavation work capacity of unit factory building is large especially, thus reduces factory building volume, not only can reduce civil engineering excavation work capacity, shorten the completion time of project, reduce construction cost, can reduce again the impact on geologic framework.Like this, for the crane in bridge type of the ultrahigh pump lift be arranged in factory building, its height and width the smaller the better.
The lifting mechanism of general conventional bridge hoisting crane adopt single laminate roll around or common multilaminate coiled.Single laminate roll around lifting mechanism, only to reel on reel one deck with steel cable, this structure design drum diameter is large, and retarder width between centers is large, simultaneously lifting mechanism Gao Erkuan, causes complete machine height, width large, and deadweight is also large, and overall performance is low.
Another kind of common multilaminate coiled lifting mechanism, continues the winding second layer or more layer after being rolled up ground floor with steel cable on reel again.Although this structure design reel length can reduce greatly, steel rope arrangement is easily chaotic, wearing and tearing.Some uses rope-arranging mechanism, but effect is also undesirable.

In the technical program, hoisting drum is double crosslinking drum structure, and two fag ends of same group of steel rope are fixed on double crosslinking drum end simultaneously, and steel rope divides and two-layerly up and down to reel simultaneously.Along with steel rope lays out double crosslinking drum, Steel wire rope discharge end progressively moves to double crosslinking drum end; Otherwise along with steel rope is around entering reel, Steel wire rope discharge end progressively moves in the middle part of double crosslinking drum;
Fixed pulley beam is arranged in the centre of lifting motor and double crosslinking drum, and its two ends are supported on end carriage I and end carriage II respectively, and be arranged in parallel in the middle part of fixed pulley beam two groups of fixed pulley groups, and fixed pulley is parallel to reel.In the technical program, adopt without trolley frame curb girder carrying speed regulating crane car structure, the angle of steel rope and double crosslinking drum controls all the time in more among a small circle, and adopt many multiplying powers, the pulley center of suspension hook running block is parallel to the pulley center of fixed pulley group, upper strata steel rope and lower floor's steel rope Stagger-wrap on fixed pulley and movable pulley.。
As preferably, above-mentioned a kind of twin-laminate roll around lifting mechanism in fixed pulley and movable pulley be parallel to double crosslinking drum, first group of fixed pulley group and second group of fixed pulley group are arranged in parallel in fixed pulley beam, and first group of running block and second group of running block are arranged in parallel in lifting hook pulley group; Steel rope is divided into two groups, is wound on the both sides of double crosslinking drum respectively.
As preferably, above-mentioned a kind of twin-laminate roll around lifting mechanism in two groups of steel ropes walk around all pulleys in homonymy fixed pulley group and running block respectively, and upper strata steel rope and the lower floor's steel rope intersection of often organizing steel rope walk around fixed pulley or movable pulley, define the wiring system of intersection, by the layout of two groups of fixed pulley groups, make steel rope non-interference when cross winding.
As preferably, above-mentioned a kind of twin-laminate roll around lifting mechanism in the angle of plug helix line of centers of steel rope line of centers and double crosslinking drum control all the time within the scope of 3.5 °.
Beneficial effect:
(1) double-layer wire rope reels simultaneously, steel rope marshalling, and there will not be job-hopping, disorder cable phenomenon, steel rope abrasion is little, prolonging service life of steel wire.
(2) due to double crosslinking drum contraction in length, thus trolley span reduces, and then the corresponding reduction of complete machine width, and suspension hook Derivative limit on the left or on the right size reduces about 30%, the corresponding reduction of factory building length, for underground excavation factory building, can save the investment of a large amount of civil engineering.
(3) adopt twin-laminate roll around lifting mechanism technology, can optimizing overall performance and reduce project total cost, particularly for this clean energy resource of Hydropower Development, is a kind of environmentally friendly novel product.
