Description

Technical Field

[0001] The utility model belongs to the technical field of shipbuilding, and in particular relates to a lifting and adjusting dock pier. Background Art

[0002] In the field of offshore floating natural gas liquefaction (FLNG) construction, shipbuilding in dock is the current mainstream construction method. Previously, the hull was loaded with fixed dock piers (cement blocks + fixed dock piers + wedges). Since the piers need to be removed for painting or opening fire, it is difficult to remove the wedges by knocking. Usually, the wedges need to be cut and hammered repeatedly to achieve the purpose of separation from the hull, which not only wastes manpower, but also the wedges are deformed due to knocking and cannot be reused, causing certain waste.

[0003] Through prior art search, it was found that the publication number is CN205652307U, which discloses a quick-detachable support for ship launching dock, including an upper box, a lower box and a quick-detachable wedge. The quick-detachable wedge passes through the lower box from the side and slides with it. The lower end of the upper box is inserted into the lower box and placed on the top inclined surface of the quick-detachable wedge. The utility model can be integrated with the ship dock. The quick-detachable wedge and the upper box can accurately control the upper and lower heights of the support based on the principle of bevel complementarity and combined with the self-gravity of the hull to ensure the height requirements of the construction size. The support descent process is safe and controllable, not easy to fall off, and easy to operate, ensuring that the dock support device can adjust the height conveniently and quickly during the construction, launching or repair of the ship, which can not only meet the precise size of the hull, but also ensure the safe and reliable launching of the hull.

[0004] However, in the above technical solution, the upper and lower boxes are only limited by the frame body for sliding up and down cooperation. When the frame body is deformed, it cannot be ensured that the upper and lower boxes are in the same vertical plane, and the wedge block and the upper box body are only fixed by friction, which is unstable.

The through holes 15 are provided for the wedge-shaped adjustment plate 3 to be inserted. Further, a reinforcing plate 4 is provided at the bottom of the through hole 15. The wedge-shaped adjustment plate 3 can be inserted into the through hole 15 along the reinforcing plate 4. The reinforcing plate 4 is adapted to the wedge-shaped adjustment plate 3. When in use, the reinforcing plate 4 supports the wedge-shaped adjustment plate 3, thereby improving the stability of the bottom plate 11. In some embodiments, forklift grooves 6 are symmetrically provided on both sides of the lower side plate 12 to facilitate the forklift to transport the dock pier.

[0036] The lifting seat 2 includes a support plate 21, and two top plates 22 are provided at the bottom of the support plate 21. The two top plates 22 are respectively located on the same vertical plane as the two through holes 15. The bottom of the top plate 22 has an oblique angle, and the inclined surface of the oblique angle fits the inclined surface of the wedge-shaped adjustment plate 3. When the lifting seat 2 is inserted into the base 1, the wedge-shaped adjustment plate 3 is inserted, and the inclined surface of the wedge-shaped adjustment plate 3 fits the bottom of the top plate 22. The height of the dock can be adjusted by tapping the wedge-shaped adjustment plate 3 along the direction of the through hole 15. Two guide plates 23 are provided at the bottom of the support plate 21. The guide plates 23 are triangular in front view. On the one hand, the guide plates 23 can strengthen the support plate 21 and the top plate 22. On the other hand, the guide plates 23 can also be vertically inserted into the guide groove 14 to limit the lifting of the lifting seat 2.

[0037] Furthermore, upper side plates 24 are provided on both sides of the bottom of the support plate 21, and the bottom of the upper side plates 24 is arched to improve the supporting strength of the support plate 21, and the upper side plates 24 are arranged to fit the inner side of the lower side plates 12, and the through holes 15 are arranged to fit the inner side of the stop plate 13, that is, when the jacking seat 2 is inserted into the base 1, the upper side plates 24 fit the inner surface of the lower side plates 12, and the top plate 22 fits the inner surface of the stop plate 13. The jacking seat 2 and the base 1 are positioned by the fitting of the upper side plates 24 and the lower side plates 12, and by the fitting of the inner surface of the stop plate 13 and the top plate 22, and are inserted and positioned with the guide plate 23 and the guide groove 14 to ensure that the jacking seat 2 is always fitted with each vertical surface of the base 1, thereby ensuring that the jacking seat 2 and the base 1 remain in a vertical plane, and that the top plate 22 can accurately fall on the inclined surface of the wedge-shaped adjustment plate 3, thereby improving the stability of the dock pier lifting.

[0038] It is calculated that each dock pier in the FLNG project bears an average load of 73 tons. The thickness of the wedge of the dock pier is 30MM, and the contact area of ​​the wedge edge is 80%. Through calculation, the ballast N can be obtained as follows: N*COSΘ<Σallowable stress*80%contact surface area, N<3.1*10 Newton, that is, a single pier can bear 310 tons, so the design ballast of the dock pier meets the requirements.

[0039] The working principle of this embodiment is as follows: first, the lifting seat 2 is inserted into the base 1, and it is ensured that the vertical surfaces are in contact, and the guide plate 23 is inserted into the guide groove 14, and then the wedge-shaped adjustment plate 3 is inserted from the through hole 15. The lifting and lowering of the lifting seat 2 can be adjusted by knocking the wedge-shaped adjustment plate 3 along the direction of the through hole 15, that is, the height of the dock pier can be adjusted.
