Description

I-steel special hoisting combination rigging

Technical field

The utility model relates to a kind of lifting fixture of shaped steel, and particularly a kind of I-steel is specialLifting combination rigging.

Background technology

At present, the lifting of industrial building I-steel, H shaped steel, the mode that generally all adopts suspension hook to lift by crane,But suspension hook lifting H shaped steel has certain risk, when lifting, need people to treat itself and the wing for pinning suspension hookAfter plate tension, could lift by crane, and lift and can not ensure once to arrive accurate destination, but extension after landingHook will come off, and be not easy to again adjust shaped steel position, thereby it is low to cause lifting efficiency.

Utility model content

The technical problems to be solved in the utility model is the above-mentioned defect that how to overcome prior art, providesA kind of I-steel special hoisting combination rigging.

For solving the problems of the technologies described above, this I-steel special hoisting combination rigging comprises cable wire and hook cardTool, is characterized in that: described hook jig has two, each hook jig comprise square substrate andTwo pairs of yokes, the two pairs of yokes are separately positioned on the arranged on left and right sides of square substrate one side, the two pairs of yokes itSpacing is more than or equal to the riser thickness of I-steel to be lifted; Difference on opposite face between every pair of yokeBe provided with protruding tooth, the distance between relative protruding tooth is more than or equal to top plate thickness or the end of I-steel to be liftedPlate thickness, is also provided with fixing suspension ring and a control draw ring, described cable wire on each hook jigTwo ends be separately fixed on the fixing suspension ring of two hook jigs, and be furnished with dropout drag hook, this dropoutDrag hook is made up of fine steel rib, this fine steel rib diameter between 6～8 millimeters, fine steel rib one end hook,The fine steel rib other end curves triangle shank.

Need to lift I-steel time, only need to be by two hooks of this I-steel special hoisting combination riggingJig is stuck on the two ends of I-steel, makes two pairs of yokes be stuck in the top board both sides of I-steel,Middle across riser. After having lifted, as long as firmly control draw ring with dropout drag hook, by hook jig fromThe two ends of I-steel pull down. So design, difficult drop-off on the one hand, and after having hung,With the operation of dropout drag hook, convenient and safe.

As optimization, it also comprises a fixed pulley with safety hook, described in described cable wire strides acrossFixed pulley. So design, be convenient to adjust the attitude of I-steel hoisting process.

The utility model I-steel special hoisting combination rigging has simple in structure, safe and convenient to useAdvantage, is applicable to the various I-steel of lifting, H shaped steel.
