The specific embodiment
For further understanding technology contents of the present invention, characteristics and effect, the following examples of giving an example now, and be described with reference to the accompanying drawings as follows:
Consult accompanying drawing 1 to Figure 11.
Embodiment 1
Marine floating oil tanker mooring anchor chain is used clump weight, is cast to accomplish to weld by two piecemeals to constitute an integral body in advance again.Clump weight 5 is provided with anchor chain draw-in groove 11; Two piecemeal junctions are provided with and promote screw mandrel 10 and locking pin 2, promote screw mandrel 10 and are fixed in clump weight 5, promote screw mandrel 10 and connect locking pin 2; Promote screw mandrel 10 positioning and locking pins 2 in anchor chain draw-in groove place, locking pin 2 anchor chain 12 that is used to lock.The piecemeal of clump weight 5 is provided with the locating dowel pin 15 of locking pin 2.
Promote screw mandrel 10 and be fixed in clump weight 5 through end cap 6; Promote screw mandrel 10 and be through in end cap 6 screws, end cap 6 is fixed on the clump weight 5, and promoting screw mandrel 10 has axle sleeve 3 with locking pin 2 junctions; Promote screw mandrel 10 and be stuck in the axle sleeve 3, axle sleeve 3 has screw 4 to be assembled together with locking pin 2.
The concrete structure of present embodiment and marine installation process thereof:
Marine floating oil tanker mooring anchor chain is used clump weight, and is in aggregates by two designs, and is furnished with anchor chain card, promotion screw mandrel, locating dowel pin and locking pin; During connection anchor chain is snapped in the counterweight chain, through promoting screw mandrel locking pin is inserted in the middle of the chain link, reach clump weight and anchor chain purpose of connecting, meanwhile, when the promotion screw mandrel was shifted locking pin onto certain position, locating dowel pin was in place, and locking pin is completely fixed.Individual cast is adopted in the manufacturing of clump weight, connects through Type of Welding then.
Because clump weight has adopted later-model structure design, its marine installation adopts dynamic positioning vessel to add the under-water robot mounting means, uses the Installation Modes of more performance-oriented dynamic positioning vessel, has accelerated erection schedule, alleviates installation workload, has improved work efficiency.Concrete installation process is following:
1) three tugboats carry out spacingly, make oil storage wheel bow to remaining on certain limit (come according to the position that clump weight is installed fixed), make the construction boats and ships that enough installing spaces arranged;
2) dynamic positioning vessel is in place above attachment point, and attachment point is carried out investigating before the underwater construction;
3) near the anchor chain the attachment point, tie up rigging band;
4) suspender belt is connected on the dynamic positioning vessel winch, winch upwards lifts 20 meters on anchor chain, so that anchor chain is snapped in clump weight;
5) the cleaning marine life guarantees that clump weight has enough gaps to snap in anchor chain, and the mark installment point, so that let clump weight block the chain link of appointment;
6) dynamic positioning vessel is transferred whole clump weight;
7) adjustment clump weight rigging make it pass anchor chain, and tieback is in transferring on the hook;
8) the loop wheel machine adjustment makes chain link snap in the clump weight groove;
9) pin is penetrated anchor chain and fastening;
10) suspender belt on the recovery clump weight;
11) " Invest, Then Investigate " is installed.
