Embodiment
Illustrate embodiments of the present invention below by way of specific instantiation, those skilled in the art can be by this specification
Disclosed content understands other advantages and effect of the present invention easily.The present invention can also pass through specific realities different in addition
The mode of applying is embodied or practiced, the various details in this specification can also be based on different viewpoints with application, without departing from
Various modifications or alterations are carried out under the spirit of the present invention.
According to Fig. 1, dismounting and the disengaging cabin process program schematic diagram of the marine generator group of example are originally applied.
The present embodiment is applied to the dismounting of the imperial number former ship diesel generating set of snow and goes out cabin and new generating set enters this reality of cabin
Applying the technique of example includes early-stage preparations, requirement, process.
1 show with reference to the accompanying drawings, generating set 1 (rib position 153~rib position 158) is provided with hull cabin, and (rib position is suitable for rib
Sequence is numbered, and refers to ship in the position where longitudinal length rib, and rib position is for determining the position along captain direction, phase in design
Represented when in the coordinate in ship length direction, or with #153~#158), the top of generating set 1 is provided with central station of floating dock 2, generator
The without hindrance formation in right side of 1 place platform of group hangs out passage 3.
Following is cabin technique.
1) prepare before, going out cabin
1.1st, tear plate hull detachable portion open, formed in (rib position 137~rib position 147) and hang out passage 3, hanging out passage 3 is
The temporarily isolating part in each layer deck, every layer of portable plate is removed, then form area's obstacle passage, hang out the size of passage 3 really
It is that can facilitate the dismounting and lifting of more new equipment on the basis of the size of generating set to recognize principle, hangs out the mistake of the formation of passage 3
To avoid also needing the part retained as far as possible in journey, especially with regard to the part of cable composition.
1.2nd, former shipowner's machine is hung out.
1.3rd, piping, the cable being connected with primary group of motors 1 are removed.
1.4th, the checker plate platform around the platform of generating set 1 is removed.
1.5th, the bolt that generating set 1 is connected with pedestal is removed.
1.6th, the temporary platform 4 being connected with generating set platform is lifted up into, temporary platform 4 and the place platform of generating set 1 are neat
It is flat.The size of temporary platform 4 is suitable with the size of the generator in the hull of the present embodiment, and temporary platform 4 and generating set 1 are flat
Platform connects, and extends to and hangs out the lower section of passage 3.Because the high low dimensional of double bottom platform can not accurately be learnt, temporary platform 4 is built
When, lower margin, which stays, puts certain surplus, when specific implementation process, according to actual height, carries out surplus to lower margin and repaiies
It is whole, it is ensured that the flatness of temporary platform.
1.7th, installation fixes 10 tons of hoist engines 5 in the range of generating set platform (rib position 131~rib position 133)；Having must
When wanting, and corresponding interim stiffening device is set to hull.In groove steel rail 6 when the positioning of hoist engine 5 is to pull generating set 1
Upper no component is criterion, i.e., hoist engine 5 is linearly distributed with generating set 1, groove steel rail 6.
1.8th, prepare to draw, hang rope used in generating set.
2) cabin, is gone out
2.1st, generating set 1 is jacked up at the prime time of the common base of generating set with oil pump (jack) 7.
The 2.2nd, generating set 1 is jacked up to certain height, the height is slided with auxiliary ready for installation under generator footing
Block 8 and groove steel rail 6, oil pump at the pedestal of generating set is then removed, remove damper.Then in generating set lower margin
Auxiliary slider 8 is installed with bolt by place, lays groove steel rail 6 and auxiliary fixing assembly, and track extends to interim flat from generating set
The top of platform.Sliding block 8 is corresponding with groove steel rail 6, then lets out lower oil pump (jack) 7, generating set is moved down, and generating set is held
Focus on sliding block and channel-section steel, auxiliary slider 8 is embedded into channel-section steel, and is coated with butter on the contact surface.
2.3rd, the rope of hoist engine 5 is connected on the hanger of the stem of generating set 1, being pulled by hoist engine 5 to generate electricity
Unit 1 moves to the lower edge (engine opening #149) of central station of floating dock 2 at former base seat, and loop wheel machine is then connected at its stem hanger
Rope, continue generating set being dragged to the top of temporary platform 4, the rope of loop wheel machine is then connected at the Tailing Lug of generating set
Rope；
2.4th, loop wheel machine hangs out generating set；
The generating set of replacing is hung in into cabin.Following is into cabin technique.
1st, positioning freeze change after generating set pedestal, adjustment cushion block, process pedestal bolt hole.
2nd, installation fixes 10 tons of hoist engines 5 in the range of generating set platform (#131~#133).And hull is set
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. hoist engine 5 is linearly distributed with generating set 01, groove steel rail 6.
3rd, temporary platform 4 hangs in cabin and had good positioning, and then lays groove steel rail 6 and auxiliary fixing assembly.Temporary platform 4
Size is suitable with the size of the generator after the replacing of the present embodiment, and temporary platform 4, which is placed in, hangs out the lower section of passage 3, and with generating
Machine group platform connects, flushed.The dimension width of groove steel rail 6 is suitable with the auxiliary slider 8 set on the generating set after replacing.
4th, one group of fixed pulley 9 is positioned on the bulkhead of the top afterbody (#161) of generating set 1 (#153~#158).
5th, auxiliary slider is fixed with bolt at the lower margin of generating set.
6th, entering the extraneous circumstance in cabin is：Main frame does not enter cabin, and double bottom hull structural modification terminates.
7th, hang in into cabin so that auxiliary slider 8 is dropped into channel-section steel, and contact surface smears butter.
8th, the rope of hoist engine 5 is connected on the hanger of the stem of generating set, rope connects hoist engine through fixed pulley 9
5.Hoist engine 5 is set to pull generating set 1 to move to left to set installation site (#153~#158).
9th, generating set is drawn to by central station of floating dock lower edge (engine opening #149) from temporary platform by hoist engine 5,
Then the rope that loop wheel machine is connected at its stem hanger is extractd, extracts the rope that loop wheel machine is connected at the Tailing Lug of generating set,
Hoist engine works on.
10th, when treating that generating set 1 is drawn to set installation site by hoist engine 5, below the pedestal of generating set
Oil pump (jack) 7 is set, then by oil pump (jack) 7 by generating set 1 upwards top to certain altitude (height with
The auxiliary slider and groove steel rail below generator footing can be removed).
11st, after removing auxiliary slider 8 and groove steel rail 6, oil pump (jack) 7 is unloaded, generating set 1 is moved down and drops down onto
On the pedestal to have freezed.Then it is fixed on pedestal, that completes generating set enters cabin installation.
12nd, temporary platform 4 and its auxiliary fixing member are removed.
The above-described embodiments merely illustrate the principles and effects of the present invention, not for the limitation present invention.It is any ripe
Know the personage of this technology all can carry out modifications and changes under the spirit and scope without prejudice to the present invention to above-described embodiment.Cause
This, those of ordinary skill in the art is complete without departing from disclosed spirit and institute under technological thought such as
Into all equivalent modifications or change, should by the present invention claim be covered.
