The utility model discloses when hoist and mount pump tower, the influence of uncertain factors such as morning and evening tides and stormy waves is overcome to the theoretical interval on increase pump tower bottom and hull dome deck, can guarantee the smooth hoist and mount of pump tower.
Description
Technical field
The utility model relates to the technical field of shipbuilding, particularly a kind of crossbeam suspender and 17.2 ten thousand m
3lNG ship pump tower hanging method.
Background technology
Pump tower crane dress is the large technical barrier of one in LNG ship manufacture process, and be also an important production node, the cycle influences of progress to follow-up tailing in work that pump tower crane fills is larger.
17.2 ten thousand m
3lNG ship and former 14.7 ten thousand m
3lNG ship is compared, and hull and pump tower height degree all increase 700mm in design, amounts to and increases 1400mm.Simulate as calculated, if construct according to former hanging method, when pump tower crane fills, pump tower lowermost end is only higher than hull dome deck 78mm, considers the impact of the uncertain factor such as tide and stormy waves, and pump tower crane dress exists larger risk.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of crossbeam suspender and 17.2 ten thousand m
3lNG ship pump tower hanging method, when making lifting pump tower, the theoretical pitch of pump tower bottom and deck in ship structure increases, and has enough surpluses, overcomes the impact of the uncertain factor such as tide and stormy waves, can ensure the smooth lifting of pump tower.
For achieving the above object, technical solution of the present utility model is as follows:
A kind of crossbeam suspender, comprise suspender body and two suspension ring, its feature is, described suspension ring are separately positioned on the left and right sides of described suspender body lower end, two symmetrical supports are also provided with in the inner side of the lower end of suspender body, suspension ring, be provided with connecting portion in the central upper end of described suspender body, this connecting portion have two through holes.
The spacing of two described suspension ring is 3500mm, and the thickness of suspension ring is 65mm, and aperture is 70mm.
Two leg spacing of two described supports are 2000mm.
Crossbeam suspender described in utilization is to 17.2 ten thousand m
3lNG ship pump tower carries out the method lifted, and it is characterized in that, the method comprises the steps:
1. install suspension ring by pump tower, the distance making pump tower upper lift ring distance pump tower top end is 4985mm;
2., during pump tower crane dress, hauling rope is tied up at pump tower bottom, by two high hanging, pump tower is winched to harbour from pump tower room;
3. be connected with the connecting portion of crossbeam suspender by two pieces of pins by the suspension hook of crane, be connected, slowly holded up by pump tower with suspender belt through two described suspension ring with the suspension ring on pump tower, hydraulic car coordinates crane pine hook;
4. pump tower is slowly moved to hull by crossbeam suspender and encloses trap deck annex by crane, adjustment pump tower height degree, to correct position, moves to liquid vault overthe openings, and adjustment pump tower is to liquid vault opening middle position, have high input hauling rope bilge portion, slow reduction pump tower, pump tower bottom enters cabin, and lifting work personnel hold hauling rope, traction pump tower direction, continue slowly to reduce pump tower, until pump tower is seated on the pump column foot seat bottom cargo tank, pump tower lift hook unhooking.
Compared with prior art, the beneficial effects of the utility model are:
1) in conjunction with 17.2 ten thousand m
3suspension ring, by changing the position of pump tower upper lift ring, are moved down by the design of LNG ship pump tower, make the distance of the distance of the suspension ring on pump tower pump tower top end be increased to 4985mm by 4250mm, save height 735mm.
2) adopt novel cross-beam suspender, save lifting rope and the shackle of the row of hanging top, can reduce and hang the height of array pitch from suspension hook, reduce height 970mm compared with the former row of hanging.
3) when lifting pump tower, increasing the theoretical pitch on pump tower bottom and hull dome deck, overcoming the impact of the uncertain factor such as tide and stormy waves, the smooth lifting of pump tower can be ensured.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model center member suspender.
Detailed description of the invention
By reference to the accompanying drawings the utility model is further described by the following examples.
Refer to Fig. 1, Fig. 1 is the structural representation of the utility model center member suspender, as shown in the figure, a kind of crossbeam suspender, comprise suspender body 1 and two suspension ring 2, described suspension ring 2 are separately positioned on the left and right sides of described suspender body 1 lower end, and in the lower end of suspender body 1, the inner side of suspension ring 2 is also provided with two symmetrical supports 3, be provided with connecting portion 4 in the central upper end of described suspender body 1, this connecting portion 4 have two through holes.Crossbeam suspender conducts oneself with dignity 1.38 tons, rated load 40 tons.Suspender lateral length 4000mm, top pin width between centers suspender support bottommost height 1280mm.Suspender upper end is directly connected with suspension hook by the pin of 2 pieces of diameter 110mm, 2 pin spacing 365mm, pin centre distance suspender main body upper end level 290mm.So save lifting rope and the shackle of the row of hanging top, can reduce and hang the height of array pitch from suspension hook, reduce height 970mm compared with the former row of hanging.The row of hanging lower end is provided with 2 suspension ring, suspension ring thickness 65mm, aperture 70mm, suspension ring centre distance pin center 980mm, and distance suspender body height 250mm, two suspension ring spacing 3500mm, connect the suspension ring on pump tower by suspender belt.Suspender lower end is provided with 2 supports for shelving, and span is 700mm, and supporting leg bottom is apart from suspender main body 550mm, two leg spacing 2000mm.
Concrete hanging method of the present utility model is as follows:
1.. at prefabricated 17.2 ten thousand m
3during LNG ship pump tower, according to design, pump tower upper lift ring installation site is moved down into preset height, makes the distance of the distance of the suspension ring on pump tower pump tower top end be increased to 4985mm by 4250mm.
2.. before pump tower crane dress, according to tidal level, drauht situation, the concrete period of selected pump tower crane dress.17.2 ten thousand m
3lNG ship is docked in Donggou 7 numbering head, during the tidal level 0.6m drauht 5.6m of high bridge port, carries out the die-filling plan of pump tower crane.
3.. during pump tower crane dress, hauling rope is tied up at pump tower bottom.First with two high hanging, pump tower is winched to harbour from pump tower room.Be connected with crossbeam suspender by 2 pieces of pins by 45 tons of hoist lifting hooks, be connected, slowly holded up by pump tower with suspender belt through 2 suspension ring bottom crossbeam suspender with the suspension ring on pump tower, hydraulic car coordinates 32 tons of crane pine hooks.
4.. pump tower is slowly moved to hull by crossbeam suspender and encloses trap deck annex by crane, and adjustment pump tower height degree, to correct position, moves to liquid vault overthe openings.Adjustment pump tower is to liquid vault opening middle position, and have high input hauling rope bilge portion, slowly reduces pump tower.Pump tower bottom enters cabin, and lifting work personnel hold hauling rope, traction pump tower direction, continues slowly to reduce pump tower, until pump tower is seated on the pump column foot seat bottom cargo tank, and pump tower lift hook unhooking.
