A kind of large-scale girder bottom hoisting method, its lifting step is as follows:
(1) before the lifting case beam, will have case beam bracket that rubber plinth and both sides block put down earlier and winch to by the beam making bench again by fork truck with rope traction to the positive center of flank indentation, there with the 50t crane;
(2) lead chain bottom hook and transfer and unload buckle to joist the shackle bolt is fixed by 8t being pulled at the hole for hoist place of back both sides, lead chain top and be fixed on top board hole for hoist side by two secondary holes for hoist, and tension leads chain joist is hung ground, and is closely connected substantially with the case soffit.Last joist both sides block;
(3) two carrying implements run to directly over the bale handle district of revealing all the details, by the top board hole for hoist of case beam, hoist cable lower end anchor head is transferred to the joist both sides, then with manually hoist cable being pushed the draw-in groove plate, spacing with anti-skidding bearing pin to hoist cable, will lead chain at last and be relaxed to state of nature;
(4) carrying implement slowly promotes the top suspender, makes joist rubber plinth and case soffit closely connected;
(5) two carrying implements hoist the case beam synchronously to certain altitude, and are synchronously traversing to carrying implement girder span centre position then;
(6) two the synchronous longitudinal removal case of carrying implement beams are to beam strorage area, and accurately the placing box beam is to depositing on the beam pedestal;
(7) manually once more joist is led the chain tension, its total weight is born by leading chain;
(8) bearing pin of joist location is pulled out, the top suspender is slowly transferred the hoist cable anchor head to the draw-in groove plate, manually hoist cable is released joist, and carrying implement hanging beam dolly breaks away from the case beam with hoist cable fully through hole for hoist then;
(9) manually lead chain joist put to ground, joist is hauled out from case beam bottom transverse by fork truck and 1t winch with joist, again with the handling of 100t carrying implement to specifying deposit position.
The effect of invention
Invention is owing to adopt the joist of revealing all the details, the hoist cable case beam of slinging, the top suspender adopts " three suspension centres " to guarantee the suspension centre stress equalization simultaneously, therefore not only can guarantee the land movement of the case beam shipment process safe, reliable and stable of going to sea, and be skillfully constructed, safe and reliable, easy and simple to handle.
