Description
Technical field
The present invention relates to a kind of bridge crane hoisting mechanism, relate in particular to the lifting mechanism of great type crane facility, belong to the crane facility technical field.
Technical background
Along with the long-term needs of clean energy resource, domestic water power has obtained development faster, and large quantities of huge units appear in the continuous lifting of the design of hydraulic generator unit and manufacturing capacity.In the large hydropower station project, the excavation work capacity of unit factory building is big especially, thereby reduces the factory building volume, not only can reduce civil engineering excavation work capacity, shortens the completion time of project, reduces construction cost, can reduce the influence to geologic framework again.Like this, for the crane in bridge type of the ultrahigh pump lift in being arranged in factory building, its height and width are 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 at the reel one deck of reeling, this structure design drum diameter is big for same steel rope, the retarder width between centers is big, lifting mechanism Gao Erkuan simultaneously causes complete machine height, width big, it is also big to conduct oneself with dignity, and overall performance is low.
Another kind of common multilaminate coiled lifting mechanism, same steel rope continues the coiling second layer or more multi-layered again after reel is rolled up ground floor.Though this structure design reel length can reduce greatly, steel rope is arranged chaotic easily, wearing and tearing.Some uses rope-arranging mechanism, but effect is also undesirable.
Summary of the invention
The present invention has overcome above-mentioned the deficiencies in the prior art, and its purpose is to provide a kind of lifting mechanism of novel double-layer coiling.
The technical solution adopted for the present invention to solve the technical problems is:

The fixed pulley group comprises first group of fixed pulley group, second group of fixed pulley group; Running block comprises first group of running block, second group of running block; Lower floor's cable wire end of same group of steel rope is fixed on the end of double crosslinking drum by the cable wire end anchor fitting, walk around first group of running block, first group of fixed pulley group successively, after oppositely, walk around first group of running block, first group of fixed pulley group again, again around becoming the upper strata steel rope above lower floor's steel rope of double crosslinking drum, the fag end of upper strata steel rope fixes by the fixing cable wire end anchor fitting of lower floor's steel rope;
Lower floor's cable wire end of another group steel rope is fixed on the end of double crosslinking drum by the cable wire end anchor fitting, walk around second group of running block, second group of fixed pulley group successively, after oppositely, walk around second group of running block, second group of fixed pulley group again, again around becoming the upper strata steel rope above lower floor's steel rope of double crosslinking drum, the fag end of upper strata steel rope fixes by the fixing cable wire end anchor fitting of lower floor's steel rope;
In the technical program, hoisting drum is the double crosslinking drum structure, and two fag ends of same group of steel rope are fixed on the double crosslinking drum end simultaneously, and steel rope divides two-layer coiling simultaneously up and down.Along with steel rope lays out double crosslinking drum, progressively move to the double crosslinking drum end steel rope rope-out end; Otherwise, along with steel rope around going into reel, the steel rope rope-out end is progressively mobile to the double crosslinking drum middle part;
The fixed pulley beam is arranged in the centre of lifting motor and double crosslinking drum, and its two ends are supported on respectively on end carriage I and the end carriage II, the two groups of fixed pulley groups that are arranged in parallel in the middle part of the fixed pulley beam, and fixed pulley is parallel to reel.In the technical program, adopt no trolley frame curb girder carrying speed governing crane carriage structure, the angle of steel rope and double crosslinking drum is controlled 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, and upper strata steel rope and lower floor's steel rope are in fixed pulley and the staggered winding of 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 the fixed pulley beam, and first group of running block and second group of running block are arranged in parallel in the 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 the running block respectively, and the upper strata steel rope of every group of steel rope and lower floor's steel rope intersect walks around fixed pulley or movable pulley, formed the wiring system of intersecting, by the layout of two groups of fixed pulley groups, make steel rope mutually noninterfere 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 in 3.5 ° of scopes.
Beneficial effect:
(1) the double-layer wire rope is reeled simultaneously, and job-hopping, disorder cable phenomenon can not appear in the steel rope marshalling, and steel rope abrasion is little, prolongs steel rope service life.
(2) because the double crosslinking drum contraction in length, thereby trolley span reduces, and then the complete machine width is corresponding reduces, and suspension hook left and right sides limit size dwindles about 30%, and the corresponding reduction of factory building length for the underground excavation factory building, can be saved a large amount of civil engineerings investments.
(3) adopting twin-laminate roll around the lifting mechanism technology, can optimize the complete machine performance and reduce project total cost, particularly for this clean energy resource of Hydropower Development, is a kind of environmentally friendly novel product.
