Description

3600 ton hangs row

Technical Field

The invention relates to the field of FPSO construction and modification, in particular to a 3600-ton lifting raft for folding or unloading large modules on the upper part of an FPSO.

Background

For the sea crane with 4 hook heads, the sea hook heads cannot be fixed under the condition of no auxiliary tool, and the included angle formed during hoisting can cause the steel wire rope to jump the groove or the hook heads to reduce the bearing capacity in a certain included angle range for load reduction and use. And the hoisting point setting of large-scale module often does not match with the interval of sea hook gib head again, can't make sea hook gib head not produce the contained angle at the hoist and mount in-process, is very unfavorable like this to the large-scale module that will hoist, thereby can cause the gib head overweight unable lifting hook.

Disclosure of Invention

In order to solve the problems, the invention provides a 3600-ton hanging raft, which aims to achieve the purposes of fixing a hook head of a marine crane, avoiding an included angle generated by the hook head of the marine crane in the hoisting process and further avoiding groove jumping and load reduction, and adopts the technical scheme that:

a3600-ton lifting raft comprises two 1800-ton lifting rafts arranged side by side, wherein the 1800-ton lifting raft is provided with a square lifting beam, and reinforcing plates which are transversely and longitudinally staggered are welded inside the lifting beam. The lifting beam is characterized in that upper lifting lugs are welded at the tops of two ends of the lifting beam, 5 groups of lower lifting lugs are welded on the left side and the right side below the lifting beam respectively, a lower connecting shaft is fixed in the middle of each lower lifting lug, each lower connecting shaft is a horizontally arranged circular pipe, and two ends of each lower connecting shaft are communicated. The two upper lifting lugs of the 1800-ton lifting line are in one-to-one correspondence, an upper connecting shaft is fixed between the lifting shafts of the 1800-ton lifting line, the upper connecting shaft is a circular pipe which is transversely arranged, two ends of the upper connecting shaft are communicated, a steel wire rope penetrates through the upper lifting lugs and the upper connecting shaft and is connected with a sea lifting hook head, and the steel wire rope penetrates through the lower lifting lugs and the lower connecting shaft and is connected with a lifted object.

In the 3600-ton hanging row, furthermore, 5 groups of the lower lifting lugs are arranged at equal intervals, and the intervals are 2.5 meters.

In the 3600 ton lifting sling, furthermore, the upper lifting lug is connected with the upper connecting shaft through a connecting member, one end of the connecting member is connected with the upper lifting lug through a fixing pin, and the other end of the connecting member is fixed with the upper connecting shaft through a fixing pin.

In the 3600-ton hanging strip, clamping plates are further fixed on two sides of the connecting member and at the connecting position of the connecting member and the upper lifting lug; clamping plates are fixed on two sides of the connecting component and the upper connecting shaft.

In the 3600-ton hanging strip, clamping plates are further fixed on two sides of the lower connecting shaft and two sides of the lower lifting lug connected with the lower connecting shaft.

3600 ton hanging row above, further, the 1800 ton hanging row has an overall length of 26 meters.

The structure that the steel wire rope penetrates through the upper connecting shaft and the lower connecting shaft saves the use of shackles, can protect the steel wire rope to a certain extent and prolong the service life of the steel wire rope, fixes the sea hook head by the structural design, ensures that the sea hook head is maintained in an original state and does not generate an included angle when an object is hoisted, and further avoids the reduction of hoisting tonnage caused by the generation of the included angle. The lower lug of 1800 tons of row of hanging below can hang the wire rope circle and directly be connected with the module, also can connect supporting riggings such as lifting bar earlier, is connected with the module through the lifting bar. The lifting lugs below the 1800 ton lifting line can be used symmetrically, asymmetrically, independently or in combination. The asymmetric use of lug can also treat the eccentric problem of hoist and mount module by effectual solution, can balance the atress of sea crane gib head to a certain extent.
