Abstract
A kind of crane hoisting mechanism wire rope winding mechanism, it includes reel, fixed pulley and movable pulley, one end of first layer steel wire rope on reel is fixed on one end of reel, downwards around to steel wire rope after movable pulley upwards about to fixed pulley, fixed still further below around to the other end for being wound into reel after another movable pulley upwards around to after fixed pulley, when winding second layer steel wire rope, one end fixing card of second layer steel wire rope is arranged on the position after first layer wirerope-winding 23 encloses, downwards around to second layer movable pulley again to around to second layer fixed pulley, steel wire rope is fixed around the other end being eventually returned to the second layer another movable pulley on reel first layer steel wire rope still further below after being wound on the second layer fixed pulley.The first layer steel wire rope on reel is wrapped in as guide groove of the internal layer as second layer steel wire rope, ectonexine steel wire rope is simultaneously wound, and the fixed pulley of the fixed pulley and the second layer staggers one apart from installation below reel.
Description
Technical field
The present invention relates to a kind of wirerope-winding mechanism, especially suitable for being used on big elevating height crane.
Background technology
Current big elevating height crane, there is following several ways, first, increasing drum diameter or length, this method structure
It is simple and easy, but the undue drum diameter that increases can bring the increase of lifting mechanism height, and the model of reductor also increases therewith, into
This is lifted therewith, and lengthening reel can cause steel wire rope to increase the drift angle of pulley and reel, aggravate the abrasion of steel wire rope, very
To the situation that groove skipping of steel rope while occurs, second, general dual layer is wound, this method is simple, the intermediate pressure rope of generally use, volume
Cylinder both ends add hoop, and first layer steel wire rope to both ends from winding among reel, the often first layer steel wire rope arrangement of this canoe
Very neatly, when but arriving the second layer, because the second layer does not have groove, the situation of random flake down often occurs, and steel rope abrasion is very
Severity, the occasion being only used for infrequently use.
The content of the invention
The task of the present invention is to propose that a kind of inside and outside steel wire rope is simultaneously wound, steel wire rope is not easy to wear, service life length, has been made
A kind of crane hoisting mechanism wire rope winding mechanism that the cost of heavy-duty machine substantially reduces.
The task of the present invention is done in such a way that it includes reel, fixed pulley and movable pulley, it is characterised in that：On reel
One end of first layer steel wire rope be fixed on one end of reel, downwards around to steel wire rope after movable pulley upwards about to fixed pulley, around
Fixed still further below around to the other end for being wound into reel after another movable pulley upwards after to fixed pulley, wind second layer steel wire rope
When, the position that one end fixing card of second layer steel wire rope is arranged on after first layer wirerope-winding 2-3 circles, downwards around to second
Layer movable pulley is again to around to second layer fixed pulley, and steel wire rope is still further below around another to the second layer after being wound on the second layer fixed pulley
The other end that one movable pulley is eventually returned on reel first layer steel wire rope is fixed.The first layer steel wire rope being wrapped on reel is made
For guide groove of the internal layer as second layer steel wire rope, ectonexine steel wire rope is simultaneously wound, the fixed pulley of the fixed pulley and the second layer
The distance that staggers below reel is installed.
The present invention has the following effects that：It is huge that the technical program solves big elevating height jack machinism well, steel wire
Rope quick abrasion and unstable problem, manufacturing process is easy, substantially reduces the cost of crane.
Brief description of the drawings
Fig. 1 is the front view of lifting mechanism winding of the present invention；Fig. 2 is Fig. 1 side view.
Drawing explanation：1st, reel, 2, second layer steel wire rope, 3, first layer steel wire rope, 4, second layer fixed pulley, 5, fixed sliding
Wheel, 6, another movable pulley, 7, movable pulley, 8, second layer movable pulley, 9, the second layer another movable pulley.
Embodiment
Embodiment is described in detail with reference to the figures above, first layer steel wire rope and second layer steel wire rope are wound on reel, such as Fig. 1 and figure
Shown in 2, one end of the first layer steel wire rope 3 on reel 1 is fixed on one end of reel, downwards around to steel wire rope after movable pulley 7 to
On around to fixed pulley 5, consolidate still further below around to the other end for being wound into reel after another movable pulley 6 upwards around to after fixed pulley
It is fixed, when winding second layer steel wire rope 2, one end of second layer steel wire rope is consolidated after first layer steel wire rope is fixed and after winding 2-3 circles
Fixed card is arranged on the position after first layer wirerope-winding 2-3 circles, determines again to around to the second layer around to second layer movable pulley 8 downwards
Pulley 4, steel wire rope is eventually returned to roll up around to the second layer, another movable pulley 9 still further below after winding on the second layer fixed pulley
The other end on cylinder first layer steel wire rope is fixed, and is wrapped in the first layer steel wire rope on reel as internal layer as second layer steel wire
The guide groove of rope, Fig. 1 dotted lines represent first layer steel wire rope 3 and fixed pulley and the winding arrangement of another movable pulley 6, realize and show the
The winding arrangement of two layers of steel wire rope and second layer fixed pulley 4 and second layer movable pulley 8, the second layer another movable pulley.Ectonexine
Steel wire rope is simultaneously wound, the wirerope-winding structure of this mode, and row's rope is neat, and abrasion is slow, and effect is good, the He of fixed pulley 5
The fixed pulley of the second layer staggers one apart from installation below reel, so as to avoid steel wire rope from colliding.
