Large-scale component turning device described in the utility model, wherein, described suspension hook is double hook type suspension hook.
Large-scale component turning device described in the utility model, wherein, described multiple sheave block is fourfold block.
The utility model beneficial effect:
The utility model large-scale component turning device, easy and simple to handle, process is steady, has saved cost, widely applicable, is not only applicable to the upset of heavy girder steel, is also applicable to the upset of large-scale steel structure framework and equipment.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model large-scale component turning device;
Fig. 2 is A place partial enlarged drawing in Fig. 1;
Fig. 3 be the utility model large-scale component turning device multiple sheave block string around structural representation.
Below in conjunction with specific embodiments and the drawings, the utility model is described in further detail.
Detailed description of the invention
As Fig. 1, shown in Fig. 2 and Fig. 3, a kind of large-scale component turning device, comprise suspension hook 1, hoist cable 2, lifting balance support beam 3, multiple sheave block 4, steel rope 5, auxiliary little suspension hook 7 and assisted suspension cable 8, hoist cable 2 has two, suspension hook 1 is double hook type suspension hook, one end of two hoist cables 2 is connected with the two ends of lifting balance support beam 3 respectively, the other end of two hoist cables 2 is connected on two hooks of suspension hook 1, multiple sheave block 4 has two, multiple sheave block 4 is four-wheel 32 tons of coasters, two multiple sheave blocks 4 are connected respectively by the two ends of lifting rope with lifting balance support beam 3, in component 6 switching process, on two multiple sheave blocks 4, string is wound with steel cable 5 respectively, the head and the tail two ends of steel rope 5 are connected by snap ring 9, the centre of steel rope 5 walks around the pulley of multiple sheave block 4 and the bottom of component 6 successively, one end of assisted suspension cable 8 is connected on the hook of auxiliary little suspension hook 7 of crane, the other end is connected on the auxiliary lifting hole(eyelet) of component 6 bottom surface, component 6 is the crane beam of 4000 tons of hydraulic lifting apparatus, driving deck-molding 2 meters, wide 1.2 meters, long 10 meters, substance 26 tons, steel rope 5 specification is Φ 21.5mm-6 × 37+1-1850, long 20 meters, lifting balance support beam 3 is made up of Φ 108 × 4mm steel pipe, and long 2 meters, according to the weight of component, multiple sheave block 4 uses two pulleys wherein.
The using method of the present embodiment large-scale component turning device, comprises the following steps:
A () is on two suspension hooks of the suspension hook 1 being hung on crane by lifting balance support beam 3 by two hoist cables 2, two multiple sheave blocks 4 are the two ends being hung on lifting balance support beam 3 respectively;
B lifting balance support beam 3 moves to above component 6 by (), and suspension hook 1 vertical line is by the center-of-gravity position of component 6, horizontal to guarantee the component after slinging 6;
C () is then gone here and there around steel rope 5, pass → walk around member bottom section → multiple sheave block 4 second pulleys by first pulley of multiple sheave block 4 successively pass → to walk around member bottom section → multiple sheave block 4 the 3rd pulley and pass ..., the head and the tail two ends of steel rope 5 are connected by snap ring; Second multiple sheave block 4 is gone here and there around the same;
D () lifting balance support beam 3 hoists, after component 6 level hangs ground, the auxiliary little suspension hook 7 of crane is connected with the auxiliary lifting hole(eyelet) of component 6 bottom surface by assisted suspension cable 8, auxiliary little suspension hook 7 is hoisted, multiply string around steel rope 5 uniformly across pulley vibration, auxiliary little suspension hook 7 promotes side string and rises around steel rope 5, and component 7 promotes side and rotates up, and realizes the object that component 7 overturns.
The advantage of the present embodiment large-scale component turning device:
1. easy and simple to handle: because of component 6 weight by go here and there between multiple sheave block 4 and component 6 around steel rope 8 strands bear, so string around steel rope 5 can the specification of selection of small, and a little compared with the lighter softness of steel rope 5 of small dimension, it is more convenient to be that extension operates.
2. process is steady: the present embodiment turning device, component 6 is unsettled, component 6 all wt by go here and there around steel rope 5 bear, go here and there around steel rope 5 free vibration on the pulley of multiple sheave block 4, because component 6 does not contact with ground, do not formed " fulcrum ", so when component 6 is turned over critical conditions (namely the center of gravity of component 6 and fulcrum are in a vertical plane surface), can not produces and rock.
3. saved cost: the present embodiment does not adopt whipline to coordinate upset, coordinates upset according to whipline, because work capacity is little, operation rate of machinery is low, causes mechanical one-shift to waste, and increases executive cost.
4. widely applicable: the present embodiment turning device is not only applicable to the upset of heavy girder steel, be also applicable to the upset of large-scale steel structure framework and equipment.
Above-described embodiment is only be described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
