Abstract

There is provided a floating structure. The floating structure according to the present invention comprises a main body including leg wells; legs penetrating the leg wells and having cords and racks; a unit installation means positioned in the main body as surroundings of the leg wells. According to the present invention, a jacking unit is installed in the main body by the unit installation means.

First claim

The invention claimed is:

1. A floating structure comprising:
a main body including leg wells;
legs penetrating the leg wells and having cords and racks;
at least one lacking unit generating a lifting force to move the legs and the main body in the vertical direction; and
a unit installation means coupled with the main body to position the at least one jacking unit in the main body,
wherein the unit installation means comprises:
a case installation unit disposed to correspond to the cords and the racks of the legs along inner walls of the leg wells; and
a jack case installed in the case installation unit to accommodate the at least one jacking unit to move the legs in the vertical direction,

wherein the jack case is positioned in the case installation unit to prevent protrusion of the jack case above a main deck of the main body.

2. The floating structure according to claim 1 , wherein the jack case include a housing in which the at least one jacking unit is positioned;
wherein the housing comprises:
a bottom plate having passing recesses through which the cords, the racks, and an end of a brace of the legs pass vertically;
lateral plates protruded from both sides of the bottom plate;
an upper plate connecting upper ends of the lateral plates to each other and having the same passing recesses as the passing recesses of the bottom plate;
a pair of front plates connecting the lateral plates, the bottom plate, and front ends of the upper plates and spaced apart from each other by a distance such that the cords of the legs, the racks, and the end of the brace may pass therethrough in the vertical direction;
a rear plate separately coupled to rear ends of the lateral plates, the bottom plate, and the upper plate; and
bulkheads spaced apart from the front plates in parallel, connected between the lateral plates, and having installation holes that have the same size as a unit housing of the at least one jacking unit to insert the at least one jacking unit thereinto; and
finishing plates connected between the bulkheads and the front plates around the installation holes.

3. The floating structure according to claim 2 , wherein the at least one jacking unit comprises:
bearing blocks installed to the front plates;
pinion shafts rotatably coupled in the bearing blocks;
pinions coupled around the pinion shafts at rear sides of the bearing blocks;
sealings coupled around the pinion shafts at the rear sides of the pinions;
unit housings coupled with the sealings at a front side and rims of the unit housings coupled in the installation holes of the bulkheads;
gearboxes installed in the unit housings and transmitting a driving force to the pinion shafts; and
motors connected to the gearboxes to drive the gearboxes.

4. The floating structure according to claim 1 , wherein the case installation unit includes one more maintenance passage allowing access to the jack case.

5. A floating structure comprising:
a main body including leg wells;
legs penetrating the leg wells and having cords and racks;
at least one jacking unit generating a lifting force to move the legs and the main body in the vertical direction; and
a unit installation means coupled with the main body to position the at least one jacking unit in the main body,
wherein the unit installation means comprises at least unit mounting portion to receive the at least one jacking unit and positioned in the main body;
wherein the unit mounting portion includes:
openings in which the leg wells are positioned;
first unit accesses penetrating a main deck of the main body; and
second unit accesses through which the at least one jacking unit moves.

6. The floating structure according to claim 5 , wherein the at least one jacking unit comprises:
a pinion shaft having a pinion engaged with the rack;
a gearbox transmitting a driving force to the pinion shaft;
a motor driving the gearbox; and
entrance rims of the first unit accesses are formed with a raised section protruded from an upper portion of the main deck.

7. The floating structure according to claim 5 , wherein the unit installation further comprises:
guide rails extending toward the openings; and
moving carts to move the at least one jacking unit on the guide rails.

8. The floating structure according to claim 7 , wherein the moving carts comprise:
wheels rolling along the guide rails; and
a moving plate or a frame to which the wheels are rotatably coupled and on which the at least one jacking units are placed.

9. The floating structure according to claim 5 , wherein the unit mounting portion further comprises a ceiling rail type moving device;
wherein the ceiling rail type moving device comprises:
ceiling rails extending toward the openings;
a bed on which the at least one jacking unit is placed; and
rollers connected to the bed and moving while being hung from the ceiling rails.

10. The floating structure according to claim 9 , wherein the unit mounting portion further comprises brackets fixing the at least one jacking unit transported by the ceiling rail type moving device.

11. The floating structure according to claim 10 , wherein the unit mounting portion further comprises an inner door opening and closing the unit mounting portion.

12. The floating structure according to claim 11 , wherein the unit mounting portion further a support plate maintaining a horizontally-opened state of the inner door.

13. A floating structure comprising:
a main body including leg wells;
legs penetrating the leg wells and having cords and racks;
at least one jacking unit generating a lifting force to move the legs and the main body in the vertical direction; and
a unit installation means coupled with the main body to position the at least one jacking unit in the main body,
wherein the unit installation means further comprises a jacking unit recess positioned in the main body as surroundings of the leg wells;
wherein the jacking unit recess has a unit mounting space and the at least one jacking unit is installed in the unit mounting space; and
wherein the jacking unit recess comprises:
a first compartment spaced apart in a first direction of the jacking unit recess;
a second compartment spaced apart in a second direction perpendicular to the first direction; and
a third compartment communicated with the first and the second compartments to finish a side of the unit mounting spaces.

14. The floating structure according to claim 13 , wherein the at least one jacking unit comprises:
a unit housing spaced apart from the pinion engaged with the rack of the legs;
a sealing disposed between the unit housing and the pinion; and
a gearbox disposed in the unit housing and transmitting a driving force to the pinion.

15. The floating structure according to claim 14 , wherein the unit housing comprises flanges formed at a rim of the unit housing facing the jacking unit recess and the flanges are coupled with the jacking unit end recess.

16. The floating structure according to claim 14 , wherein the unit housing comprises a rim protruded from an outer surface of the unit housing wherein the rim of the unit housing is coupled with a rim stopper of the inner walls.

17. The floating structure according to claim 16 , wherein the rim of the unit housing of the at least one jacking unit and the rim stopper are overlapped with each other and coupled with each other with a plurality of bolts,
further comprising head-protective covers covering heads of the bolts.
