As shown in Figure 2; Reel 10 ' is arranged in trolley frame middle part, establishes rope-arranging mechanism 20 ' below the reel 10 ', and rope-arranging mechanism 20 ' is by the chain wheel drive on the drum shaft; Rope-arranging mechanism 20 ' is guided the steel rope on the reel 10 ' leading sheave 30 ' into and is finally guided movably fixed pulley into; Wheel or slide block are established in fixed pulley frame 40 ' bottom, through chain drive screw rod 50 ' and the removable fixed pulley of final driving, realize that suspension hook is traversing with three-in-one reductor 60 '.
Though this structure can realize that hook moves through the simple fixed pulley that moves, wiring is complicated, needs steel rope is repeatedly led, and this has just caused repeatedly multidirectional bending to steel rope, and the steel rope easy fatigue is destroyed, and the life-span reduces.In addition, steel rope also needs rope-arranging mechanism just can make the steel rope proper alignment on reel, and rope-arranging mechanism is by the chain wheel drive on the drum shaft; And through rectangular axis retarder and universal coupling, rope pulley is arranged in driving at last, the row's of realization rope function; This cover mechanism is complicated; Occur operating troubles easily, in the hoisting crane use, also need be equipped with camera and keep watch on its operation conditions, this makes whole lifting mechanism reliability reduce.In addition, the type of drive of transverse-moving mechanism is identical with prior art scheme one, the shortcoming that have also that transmission link is more, reliability and efficient reduces greatly.
Summary of the invention
Prior art exists following problem, and the one, mechanism is huge, and weight is heavier.The 2nd, steel rope is worn around complicacy, bending repeatedly, and the steel rope easy fatigue is destroyed.The 3rd, the driver train complicacy that suspension hook is traversing, reliability and efficient are low.The present invention provides dolly suspension hook transverse-moving mechanism on a kind of ship-building gantry crane; Realize that with easy driver train suspension hook is traversing; Cancellation leading sheave and rope-arranging mechanism are simplified steel rope and are worn system for winding, make steel rope all bendings in the same way at work; Avoid multinomial bending to cause fatigue, finally alleviate dolly weight, improve mechanism efficiency and serviceability.
The present invention's technical scheme that adopts of dealing with problems is:
Dolly suspension hook transverse-moving mechanism includes car frame on the ship-building gantry crane, is fixed with reel and guide rail on the vehicle frame; Guide rail is provided with the fixed pulley frame; Wherein the fixed pulley frame is provided with fixed pulley, and the two ends of fixed pulley frame also are provided with slide block or wheel, and slide block or wheel are arranged on the guide rail.Also be fixed with the suspension hook cross sliding driving device on the vehicle frame, it is characterized in that: said cross sliding driving device is a push rod, and the push rod middle part is hinged on the vehicle frame, and the top is hinged on the fixed pulley frame.Steel rope passes reel, movable pulley, fixed pulley respectively in the same way.
Said push rod is an electric drive hydraulic thruster.
Said push rod is provided with limit switch.
Said guide rail two ends are respectively equipped with positive stop.
Beneficial effect of the present invention: reel is fixing in dolly suspension hook transverse-moving mechanism on this does not move, and therefore can reduce traversing driving power, can reduce the size of car frame simultaneously.Do not use rope-arranging mechanism in this mechanism, steel rope is worn and is walked around Cheng Zhongjun bending in the same way, has improved rope service-life.The driver train of transverse-moving mechanism has adopted electric drive hydraulic thruster to simplify current driving mode, makes it simple and reliable for structure, and efficient improves.
