As it is shown on figure 3, have the suspension centre of eight equalization settings on barge 8, suspension centre is in along symmetrically arranged two rows of barge 8 long axis direction, and barge 8 and top are driven and be provided with the specific frock that 8 liftings are converted to two ends lifting between 2.Top is driven 2 lower ends and is connected to hook 3, and hook 3 lower end is connected with steel wire rope.As figure 5 illustrates, top is driven also has a set of weight sensor bearing pin 92 on 2 lower end steel wire ropes, weight sensor bearing pin 92 is arranged on special gusset piece；Special gusset piece includes upper junction plate 91 and lower connecting plate 93, upper junction plate 91 includes two pieces of symmetrically arranged risers, lower connecting plate 93 is the riser that a upper end is arranged between upper junction plate, and namely weight sensing bearing pin 92 is horizontally set on upper junction plate 91 and lower connecting plate 93 junction.As shown in Figure 4, specific frock is be arranged on the middle otic placode 7 that top is driven between hook 3 and barge 8 suspension centre；Middle otic placode 7 includes a plate 71 and is perpendicular to connecting plate 71 and is symmetricly set on the side plate 72 of connecting plate 71 both sides；Connecting plate 71 top has two connection tops and drives the suspension centre hole of 2, and biside plate 72 bottom is respectively provided with two suspension centre holes connecting barges 8；Steel wire rope is interspersed in middle otic placode 7 suspension centre hole.
Utilize the test that this system carries out as follows:
Test load includes heavy duty and hangs thing (hook counterweight) and thribble counterweight: hook 3 empty-weight and ballast amount combination weight at least can reach 1967 kips (892mt), hangs thing weight and will be loaded into top and drive hook 3；The test weight of 646 kips (293mt) will be arranged in thribble district, thribble weight with maximum 646 kips (293mt) of equivalence, or 2712 combination weights (this weight is estimated value, it is contemplated that the equipment lacked, and is likely to need weight strengthened during test) of kip (1230mt).
First all tool parts related in this being tested are weighed, and are witnessed by third party:
1000TLINK (suspension ring and hook 3) is hung top processed and drives both sides, as shown in Figure 1, it is to avoid hang steel wire rope and drive 2 both sides otic placodes interference with top, improve safety coefficient；
Gusset piece assembly assembled in advance is put in place (comprising sensor bearing pin, axle and axle sleeve), has pierced wire line thimble ￠ 172*12m simultaneously.By drilling platforms lifting and transporting equipment, it is transported to top and drives lower section, adopt 2-500T shackle, as shown in Fig. 3, Fig. 5, steel wire rope and suspension ring are connected；
Existing barge 8 is increased " eight " suspension centre, by otic placode 7 in design specialized, " 8 points " lifting is converted to " 2 points " lifting, by four groups of wire line thimble ￠ 135*35m transition.Middle otic placode 7, by wire line thimble ￠ 172*52m and 1250T shackle, drives less than 2 gusset piece combinations and couples, as shown in Figure 3, Figure 4 with top；
Require to arrange in thribble district 567+79 kip (257+36=293mt) test weight, complete by loading finished product counterweight；
In whole heavy-duty test process, will be monitored and observe at any time.If any problem occurs in process of the test, test should be suspended, release test load (if necessary), be ready to fall platform.
Concrete test procedure is as follows:
(1) pretest inspection: guarantee drilling platforms 10 hull level, confirm slide device in order, open cantilever beam 11 sliding lock, cantilever beam 11 is slid onto rotating disk 6 centre-to-centre spacing stern transom plate 75ft place, and rig floor 10 slides onto rotating disk 6 centre-to-centre spacing hull 12 centrage 0ft place, read deflection initial reading；Rig floor 10 is aport slid onto rotating disk 6 center and leaves hull 12 centrage 15ft, and read deflection；Rig floor 10 astarboard is slid onto rotating disk 6 center and leaves hull centrage 15ft, read deformation values；Regain cantilever beam 11 and arrive the rotating disk 6 suitable distance of centre distance stern transom plate；Platform is made to get out load counterweight in thribble district；567+79 kip equivalence thribble load is loaded in rig floor 10 superstructure thribble district；Afterwards, lifting hull 12, to the air gap required, pins fastening system；Sliding gib beam 11 is until rotating disk 6 centre distance stern transom plate 75ft, and when rotating disk 6 center reaches predetermined testing position, locking cantilever 11 beam sliding is locked；
(2) test one: determine that barge 8 is loaded into specific drainage amount, barge 8 of having good positioning, by hoisting rope, barge 8 is connected with platform hook 3；Sling barge 8 with winch；It is gradually increased hook load until reaching test load with the increment of test weight 50%/25%/25%；Barge 8 is not hung the water surface；After increasing weight, check well drilling winch brake every time；Record deflection after increasing weight every time；After reading final deflection under test load, release winch is until barge 8 swims in water completely slowly；Record deflection；
(3) test two: sling barge 8 with winch；Increase load until reaching test load；Band thribble counterweight slip rig floor, makes rotating disk 6 centre distance hull 12 longitudinal centre line aport 15ft；Test load records deflection after reaching, and reads final deflection under test load, and release winch is until barge swims in water completely slowly, records deflection；
(4) test three: slip rig floor 10, makes center of turntable distance hull 12 longitudinal centre line be moved to astarboard 15ft winch by larboard 15ft and slings barge 8；Increase load until reaching test load；Test load reach after record after deflection reads final deflection under test load, release winch brake slowly is until barge swims in water completely；Record deflection；
Barge 8 is transformed, and wherein barge specification is 4m(moldeed depth) * 56.2m(length) * 14m(width), its empty-weight reaches 440 tons, and ballast amount can more than 1000 tons.Inside barge 8, increase by eight " plug-in type " eye plates, each eye plate allowable load 150T, carry 1200T altogether.
Specific frock is be arranged on the middle otic placode 7 that top is driven between hook 3 and barge 8 suspension centre；Middle otic placode 7 top has two connection tops and drives the suspension centre of hook 3, and bottom has four suspension centres connecting barges 8；Top drives 2 for two points stress, and barge 8 is 8 stress, and in order to ensure stress equalization, centre needs otic placode 7 transition and conversion in design.In conjunction with virtual condition, devising middle otic placode 7, top is " two " suspension centre, and bottom is for inserting plate design, " four " suspension centre.For through Modeling Calculation, 1000T can be born；
Top is driven hook 3 lower end and is had a set of weight sensor bearing pin, and weight sensor bearing pin 92 is arranged on special gusset piece；Sensor bearing pin 92 requires that induction point straight down, and requires uniform load on axle, and otherwise read untrue causes that result of the test lost efficacy by shearing force；The intensity of gusset piece 9 is under the premise meeting cantilever beam heavy-duty test maximum load, and its thickness is not more than the width of each segmentation stress of sensor bearing pin 92, it is ensured that its uniform load.
Counterweight frame is adopted during thribble district counterweight；For installation thribble district efficient, quick counterweight, newly purchase finished product balancing weight, monolithic-150X1000X1500, weight about 1.5 tons, by the crane gear of drilling platforms self configuration, in conjunction with its elevating capacity, devise counterweight frame simultaneously, once can transport 6, be greatly improved work efficiency.
Of the present utility model ultimate principle and principal character have more than been shown and described.Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description is that principle of the present utility model is described; under the premise without departing from this utility model spirit and scope; this utility model also has various changes and modifications, and these changes and improvements both fall within the scope of claimed this utility model.This utility model claims scope and is defined by appending claims and equivalent thereof.
