Detailed Description
Referring to fig. 1-5, a reach-in hanger for offshore wind power construction comprises a hanger rod 1, wherein a first front cross beam 9 arranged in parallel is fixed at one end of the head of the hanger rod 1, a second front cross beam 8 is fixed on the hanger rod 1 at a distance from one end of the tail, a counterweight 6 is arranged at the tail of the hanger rod 1, two ends of the second front cross beam 8 are connected with a steel wire rope 3, and the other end of the steel wire rope 3 is hooked on a floating crane hook 7; the floating crane lifting hook 7 is connected with a lifting belt 4, and the lifting belt 4 is connected with a balance weight 6 through an adjusting chain block 5. The lifting appliance is a special designed and manufactured extension-type lifting appliance aiming at the condition that a structural object above a lifting place blocks and cannot be directly lifted. When the hoop of the offshore wind power berthing member is installed, the hoop can be conveniently and quickly hoisted to a designed position by using the stretching-in type lifting appliance, and installation is completed.
Further, the hanger rod 1 is made of I-shaped steel. The structural strength and stability of the whole suspender 1 are ensured by adopting the I-shaped steel material.
Further, the bottom ends of the first front cross beam 9 and the two sides of the hanger rod 1 are connected with a hand chain block 10; during hoisting, the anchor ear 11 is selectively hoisted on the corresponding side of the suspender 1 through the chain block 10 according to the position where the anchor ear 11 needs to be installed. Through the hoist and mount to staple bolt 11 that foretell operation chain block 10 can be convenient, can make things convenient for the later stage moreover to hoist its installation, adjust its mounting height.
Further, the first front cross beam 9 and the second front cross beam 8 are both made of i-steel. The material is made of the material, so that the structural strength and the stability of the material are ensured.
Furthermore, the two sides of the counterweight 6 are connected with the windlass ropes 2; the counterweight 6 adopts a centering iron block.
Example 2:
in the embodiment, the hanger rod 1 is made of H32I-steel and is 10m long; the first front cross beam 9 and the rear cross beam 8 are both made of H20I-steel and have the length of 2 m; the two steel wire ropes 3 and the 1 sling 4 form a triangular sling rope which is integrally hung on the floating crane hook 7; the adjustable chain block 5 is arranged at the tail end of the hanging strip 4; the balance weight 6 is an iron block and is welded and fixed at the rear end part of the suspender; the cable rope 2 is tied to the left and right of the balancing weight; four operating chain blocks 10 are respectively hung at two ends of the front cross beam.
