Detailed description of the invention
Below by way of specific instantiation, embodiments of the present invention being described, those skilled in the art can be by disclosed by this specification
Content understand other advantages and effect of the present invention easily.The present invention can also be added by additionally different detailed description of the invention
To implement or to apply, the every details in this specification also can be based on different viewpoints and application, in the essence without departing from the present invention
Carry out various modification or change under Shen.
According to Fig. 1, originally execute dismounting and the turnover cabin process program schematic diagram of the marine generator group of example.
The present embodiment is applied to the snow dragon dismounting of number former ship diesel generating set and goes out cabin and new generating set enters cabin. the present embodiment
Technique includes early-stage preparations, requirement, process.
1 display with reference to the accompanying drawings, (rib position is the order of rib to be provided with generating set 1 (rib position 153～rib position 158) in hull cabin
Numbering, refers to the position at longitudinal length rib place for the ship, and rib position is for determining the position along captain direction when design, quite
In the coordinate in ship length direction, or represent with #153～#158), generating set 1 be arranged over central station of floating dock 2, generating set
The without hindrance formation in right side of 1 place platform hangs out passage 3.
Following for going out cabin technique.
1) prepare before, going out cabin
1.1st, tearing plate hull detachable portion open, being formed in (rib position 137～rib position 147) and hang out passage 3, it is each for hanging out passage 3
The temporarily isolating part in layer deck, removes every layer of portable plate, then forms district's obstacle passage, hang out the confirmation of passage 3 size
Principle is with the size of generating set as benchmark, facilitate dismounting and the lifting of more new equipment, hangs out the process of passage 3 formation
In to avoid also needing the part that retains, especially with regard to the part of cable composition as far as possible.
1.2nd, former shipowner's machine is hung out.
1.3rd, piping, the cable being connected with primary group of motors 1 is removed.
1.4th, the checker plate platform around generating set 1 platform is removed.
1.5th, the bolt that generating set 1 is connected is removed with pedestal.
1.6th, lifting up into the temporary platform 4 being connected with generating set platform, temporary platform 4 flushes with generating set 1 place platform.
The size of temporary platform 4 is suitable with the size of the generator in the hull of the present embodiment, temporary platform 4 and generating set 1 platform
Connect, extend to hang out below passage 3.Because the high low dimensional of double bottom platform cannot accurately be learnt, build temporary platform 4
When, lower margin stays puts certain surplus, when being embodied as technique, according to reality height, carries out surplus to lower margin and repaiies
Whole, it is ensured that the flatness of temporary platform.
1.7th, in the range of generating set platform (rib position 131～rib position 133), installation fixes 10 tons of hoist engines 5；It is necessary
When, and corresponding interim stiffening device is set to hull.At groove steel rail 6 when the positioning of hoist engine 5 is to pull generating set 1
On do not have component to be criterion, i.e. hoist engine 5 and generating set the 1st, groove steel rail 6 is linearly distributed.
1.8th, prepare to draw, hang rope used by generating set.
2), cabin is gone out
2.1st, use oil pump (jack) 7 by generating set 1 jack-up at the prime time of the common base of generating set.
2.2nd, by generating set 1 jack-up to certain height, described height with can install under generator footing auxiliary slider 8 and
Groove steel rail 6, then removes oil pump at the pedestal of generating set, removes damper.Then use at generating set lower margin
Auxiliary slider 8 installed by bolt, and laying groove steel track 6 and auxiliary fixing assembly, track extends to temporary platform from generating set
Top.Slide block 8 is corresponding with groove steel rail 6, then lets out lower oil pump (jack) 7, and generating set moves down, and generating set holds
Focusing on slide block and channel-section steel, auxiliary slider 8 is embedded in channel-section steel, and is coated with butter on the contact surface.
2.3rd, on the hanger of the stem of generating set 1, connect the rope of hoist engine 5, pulled generating set by hoist engine 5
1 moves to central station of floating dock 2 lower edge (engine opening #149) at former pedestal, then connects the rope of loop wheel machine at its stem hanger
Rope, continues to be dragged to above temporary platform 4 by generating set, then connects the rope of loop wheel machine at the Tailing Lug of generating set；
2.4th, generating set is hung out by loop wheel machine；
The generating set of replacing is hung in cabin.Following for entering cabin technique.
1st, the pedestal of generating set after positioning freezes and changes, adjusts cushion block, the bolt hole of processing pedestal.
2nd, in the range of generating set platform (#131～#133), installation fixes 10 tons of hoist engines 5.And hull is arranged corresponding
Interim stiffening device.There is no component as criterion on groove steel rail 6 when the positioning of hoist engine 5 is to pull generating set, i.e. roll up
Raise machine 5 to be linearly distributed with generating set the 01st, groove steel rail 6.
3rd, temporary platform 4 hangs in cabin and has good positioning, then laying groove steel track 6 and auxiliary fixing assembly.The chi of temporary platform 4
Very little with the replacing of the present embodiment after the size of generator suitable, temporary platform 4 is placed in and hangs out below passage 3, and and generator
Group platform connects, flushes.The dimension width of groove steel rail 6 with change after generating set on arrange auxiliary slider 8 suitable.
4th, on the bulkhead of the top afterbody (#161) of generating set 1 (#153～#158), one group of fixed pulley 9 is positioned.
5th, at the lower margin of generating set, auxiliary slider is fixed with bolt.
6th, the extraneous circumstance entering cabin is: main frame does not enters cabin, and double bottom hull structural modification terminates.
7th, hang in into cabin so that auxiliary slider 8 drops in channel-section steel, and contact surface smears butter.
8th, connecting the rope of hoist engine 5 on the hanger of the stem of generating set, rope passes through fixed pulley 9 and connects hoist engine 5.
Hoist engine 5 is made to pull generating set 1 to move to left to set installation site (#153～#158).
9th, by hoist engine 5, generating set is drawn to central station of floating dock lower edge (engine opening #149) from temporary platform, then
Extract the rope connecting loop wheel machine at its stem hanger, extract the rope connecting loop wheel machine at the Tailing Lug of generating set, hoist engine
Work on.
10th, when treating that generating set 1 is drawn to set installation site by hoist engine 5, arrange below the pedestal of generating set
Oil pump (jack) 7, then by oil pump (jack) 7 generating set 1 is upwards pushed up to certain altitude (described height with
The auxiliary slider below generator footing and groove steel rail can be removed).
11st, after removing auxiliary slider 8 and groove steel rail 6, unload oil pump (jack) 7, make generating set 1 move down and drop down onto
On the pedestal freezing.Then being fixed on pedestal, the cabin that enters completing generating set is installed.
12nd, temporary platform 4 and auxiliary fixing member thereof are removed.
The principle of above-described embodiment only illustrative present invention and effect thereof, not for the restriction present invention.It any is familiar with this skill
Above-described embodiment all can be modified under the spirit and the scope of the present invention or change by the personage of art.Therefore, such as
All that in art, tool usually intellectual is completed under without departing from disclosed spirit and technological thought etc.
Effect is modified or changes, and must be covered by the claim of the present invention.
