Further, described anchor fitting comprises hoist cable sheath, described sling device is fixedly installed on the middle part of hoist cable sheath, the center of described adapter plate is provided with semicircle orifice, and described hoist cable sheath is fixedly installed in the semicircle orifice of two adapter plates, and described hoist cable sheath has open slot along its length, on described hoist cable sheath, have tapped bore, described tapped bore is arranged on the outside of adapter plate, in described tapped bore, is connected with push bolt, and described push bolt is perpendicular to the sidewall setting of open slot.
Further, between the two ends of described guide wheel and adapter plate, be provided with copper packing, described copper packing is installed on bearing pin.
Further, described copper packing is tin bronze material.
Large-scale component is sling and is placed on supporting seat by common clamping suspender level, then eight these utility models are lifted into the upset junction of large-scale component by suspension rod, by push bolt, fender guard and large-scale component are fitted tightly, on fender guard guide wheel, smear grease simultaneously, again two hoist cables are around to respectively on fender guard by guide wheel, large-scale component is sling with the main hook that hang two hundred tons of purlins, while two auxiliary hooks also connect large-scale component and rise together, when rise winch to upset when desired height main hook stop, two auxiliary hooks are regained simultaneously, large-scale component passes through guide wheel scrolling realization large-scale component safety together with fender guard along hoist cable, upset efficiently.
Make hoist cable realize macrobending radius by the utility model, and change cliding friction into friction of rolling, reduce the damage of hoist cable, further realize large-scale component safety, upset efficiently.
The utility model compared with prior art has following beneficial effect.
One, the utility model improve large-scale component production efficiency and production security, reduce production costs, this device can greatly reduce the damage probability of hoist cable, lower productive costs, realize more than hundred tons large-scale component safety, produce efficiently, meet heavy mechanical equipment development and production demand.
Two, in use; eight these devices are fixed on large-scale component; article two, hoist cable is respectively around on four hoist cable fender guards; by two groups of guide wheels on hoist cable fender guard, the bending spring of hoist cable is increased greatly; carry out definite hoist cable diameter according to the tonnage of macrostructure part simultaneously; thereby determine the size of guide wheel upper rail radius and bending bearing pin; make hoist cable realize macrobending radius by this device; and change cliding friction into friction of rolling; reduce the damage of hoist cable, thereby realize large-scale component safety, upset efficiently.
Three, the utility model has improved the service life of hoist cable effectively, the method that adopts friction of rolling to substitute cliding friction avoids hoist cable in use due to the bending fracture of wire phenomenon occurring of transition, not only reduce equipment loss, and greatly improved production efficiency and safety.
