Rotatable height-adjustable marine rig

Abstract

The application relates to a rotatable height-adjustable marine tool, which comprises a fixed base used for being mounted on a ship body, and a rotating tool rotatably arranged on the fixed base and capable of being switched between a horizontal state and a vertical state relative to the fixed base. Through the above structure, the tool height can be adjusted in two modes by switching the rotating tool between the horizontal state and the vertical state relative to the fixed base. When the rotating tool is in the horizontal state, the overall tool height is low, so that the tool can effectively avoid the module hoisting path and collision; when the rotating tool is rotated to the vertical state, the tool height is increased, so that the tool can provide stable support for the upper module. The whole height adjustment process can be completed only by rotating operation, without the need of complex lifting mechanisms or auxiliary equipment, so that the operation is simple and fast, and the lateral rigidity and overturning resistance of the tool in the vertical state are effectively improved.

Description

Technical Field

[0001] This invention relates to a marine tooling, and more particularly to a marine tooling with adjustable height that can be rotated and switched between a horizontal and a vertical state relative to a fixed base, thereby achieving two-level height adjustment of the tooling. It does not require a complex lifting mechanism or auxiliary equipment and is simple and quick to operate. Background Technology

[0002] In the fields of marine engineering and large equipment transportation, marine tooling is an important support structure used to fix modular equipment or large components to transport vessels. With the rapid development of industries such as offshore oil and gas engineering and offshore wind power, the size and weight of large modules are constantly increasing, which puts forward higher requirements for the load-bearing capacity, ease of installation, and transportation safety of marine tooling.

[0003] Currently, most commonly used marine tooling employs fixed support structures, meaning the tooling is welded or bolted to the ship's deck, with a fixed support height that cannot be adjusted according to actual transportation needs. During module lifting and loading, fixed-height tooling is prone to interference and collision with the modules being lifted, increasing the risk and difficulty of the lifting operation. To address this issue, some existing technologies employ liftable tooling structures, such as those using hydraulic cylinders or screw-driven lifting mechanisms for height adjustment. However, these liftable tooling units typically require hydraulic stations, control systems, or complex mechanical transmission components, resulting in complex structures, high manufacturing costs, and the risk of hydraulic system leakage during sea transport, reducing the reliability and safety of the tooling. Furthermore, complex lifting mechanisms are prone to jamming or damage under ship rolling and vibration conditions, making maintenance difficult.

[0004] Therefore, how to achieve flexible adjustment of tooling support height while simplifying tooling structure and reducing manufacturing costs, so as to ensure both clearance space during module hoisting and loading and provide stable and reliable support, has become a technical problem that urgently needs to be solved in the field of marine engineering transportation. Summary of the Invention

[0005] To address the aforementioned deficiencies in the existing technology, this invention provides a rotatable and height-adjustable marine tooling. By rotating the tooling relative to a fixed base between a horizontal and a vertical state, it achieves two-level height adjustment of the tooling, eliminating the need for complex lifting mechanisms or auxiliary equipment, and making operation simple and quick.

[0006] To achieve the above objectives, the present invention provides a rotatable and height-adjustable marine tooling, comprising: Fixed base for mounting on the hull; The rotating fixture is rotatably mounted on the fixed base and can rotate and switch between a horizontal and a vertical state relative to the fixed base. When the rotating tooling is rotated to a horizontal position, the ocean-going tooling is at a lower height; when the rotating tooling is rotated to a vertical position, the ocean-going tooling is at a higher height. When the rotating fixture is rotated to a vertical position, the rotating fixture and the fixed base are provided with reinforcing diagonal braces on their side walls. The reinforcing diagonal braces are used to support the rotating fixture and the fixed base from the side. A detachable fastener is provided between the fixed base and the rotating fixture for fixing the rotating fixture, which is in a vertical position, to the top of the fixed base.

[0007] Traditional support fixtures generally suffer from drawbacks such as complex structure, limited load-bearing capacity, and cumbersome adjustment operations. To improve these issues, this invention achieves two-level height adjustment of the fixture by rotating it between horizontal and vertical states relative to a fixed base. This eliminates the need for complex lifting mechanisms or auxiliary equipment, making operation simple and quick.

[0008] The rotating fixture and the fixed base are rotatably connected by a rotating shaft. The fixed base has a shaft hole through which the rotating shaft passes, and the rotating fixture has a mating hole corresponding to the shaft hole.

[0009] The shaft hole is a U-shaped opening, the mating hole is a round hole, and the rotating shaft is a long bolt. The long bolt passes through the U-shaped opening and the round hole to rotatably connect the rotating fixture to the fixed base.

[0010] The fixed base includes a base plate and several lower vertical stiffeners disposed on the base plate. The top of the lower vertical stiffeners is provided with a first connecting plate, and several first fastening holes are provided on the first connecting plate.

[0011] The rotating fixture includes a top support plate, several upper vertical stiffeners disposed below the top support plate, and a bottom connecting plate disposed at the bottom of the upper vertical stiffeners. The bottom connecting plate has a second fastening hole, which corresponds to the position of the first fastening hole. The fastener passes through the first fastening hole and the second fastening hole to fix the rotating fixture to the top of the fixed base.

[0012] The upper vertical stiffening plate consists of two pieces spaced apart, and a horizontal reinforcing stiffening plate connects the two upper vertical stiffening plates.

[0013] The lower vertical stiffening plate consists of two pieces spaced apart. The fixed base also includes a diagonal brace plate, with one side of the diagonal brace plate connected to the base plate and the other side connected to the corresponding lower vertical stiffening plate.

[0014] The reinforcing diagonal brace includes a right support plate, which simultaneously abuts against the outer side of the lower vertical stiffener of the fixed base and the outer side of the upper vertical stiffener of the rotating fixture.

[0015] The reinforcing diagonal brace also includes a left support plate, which is disposed on the top of the diagonal brace of the fixed base, and the side of the left support plate abuts against the upper vertical stiffener of the rotating fixture.

[0016] The reinforcing diagonal brace also includes a second wing plate and two vertical wing plates. The two vertical wing plates are respectively located at both ends of the bottom plate, and the second wing plate is located on the top of one of the vertical wing plates.

[0017] Through the above structural design, this invention achieves two-level height adjustment of the tooling by rotating it between horizontal and vertical states relative to the fixed base. When the tooling is horizontal, its overall height is low, effectively avoiding collisions during module hoisting. When the tooling is rotated to the vertical position, its height increases, providing stable support for the upper module. The entire height adjustment process can be completed simply by rotating the tooling, without the need for complex lifting mechanisms or auxiliary equipment, making operation simple and quick. By providing reinforcing diagonal braces between the rotating tooling and the sidewall of the fixed base, when the tooling is rotated to the vertical position, the reinforcing diagonal braces simultaneously support both the rotating tooling and the fixed base from the side, effectively improving the lateral rigidity and anti-overturning capacity of the tooling in the vertical state. Compared to methods relying solely on fastener connections, this invention maintains structural stability even under ship swaying and vibration conditions, reducing safety risks caused by loose connections or structural tilting. The fixed base and the rotating fixture are secured with detachable fasteners. When the rotating fixture is in a vertical position, the fasteners reliably lock it to the top of the fixed base. This structure ensures both the robustness of the connection in the supported state and allows for quick removal of the fasteners and rotation to lower the rotating fixture when its height needs to be reduced, thus achieving a balance between adjustable support height and structural stability.

These directions or similar terms are only used to assist in explaining and understanding the various embodiments of this invention and are not intended to limit this invention.

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. However, the embodiments described are only used to illustrate the technical features of the present invention and are not intended to limit the scope of protection of the present invention.

[0021] Please see Figures 1 to 4 As shown, the present invention discloses a rotatable and height-adjustable marine tooling, mainly comprising a rotatable tooling 1, a fixed base 2, and a reinforcing diagonal brace 3. The fixed base 2 is fixedly installed on the ship's deck, providing basic support for the entire tooling. The rotatable tooling 1 is rotatably mounted on the fixed base 2, allowing it to rotate between a horizontal and a vertical position relative to the fixed base 2. The reinforcing diagonal brace 3 is disposed on the side walls of both the rotatable tooling 1 and the fixed base 2. When the rotatable tooling 1 rotates to a vertical position, the reinforcing diagonal brace 3 simultaneously supports both the rotatable tooling 1 and the fixed base 2 from the side, preventing the rotatable tooling 1 from tilting or overturning.

[0022] The fixed base 2 includes a base plate 22, which is a horizontally arranged plate structure, and its lower surface is welded and fixed to the ship's deck. Two lower vertical stiffening plates 24 are welded at intervals to the upper center of the base plate 22. The bottom of each lower vertical stiffening plate 24 is vertically welded and fixed to the upper surface of the base plate 22. A top connecting plate 26 is welded to the top of the two lower vertical stiffening plates 24, and the top connecting plate 26 is horizontally arranged, connecting the two lower vertical stiffening plates 24 into one unit. The top connecting plate 26 has four first fastening holes penetrating its upper and lower surfaces, and the four first fastening holes are distributed in a rectangular pattern.

[0023] On the outer side of a set of lower vertical stiffeners 24 located on the left, a diagonal brace 23 is provided. The diagonal brace 23 is a triangular plate structure, with its bottom surface welded to the upper surface of the base plate 22, and its right-angled side welded to the outer wall of the corresponding lower vertical stiffener 24. A first wing plate 21 is welded to the hypotenuse of the diagonal brace 23, and the first wing plate 21 extends along the hypotenuse of the diagonal brace 23. The bottom of the first wing plate 21 is welded to the base plate 22 by a vertical wing plate 33. Specifically, the lower end of the vertical wing plate 33 is welded to the base plate 22, and the upper end is welded to the bottom of the first wing plate 21, thereby providing auxiliary support for the first wing plate 21.

[0024] Above the outer sides of the two lower vertical stiffening plates 24, two ear plates 25 are welded on each side. The two ear plates 25 on the left lower vertical stiffening plate 24 are spare ear plates, while the two ear plates 25 on the right lower vertical stiffening plate 24 are main ear plates. Each ear plate 25 has U-shaped bolt holes for easy bolt installation and removal.

[0025] The rotating fixture 1 includes a top connecting plate 12, which is a horizontally arranged plate structure. A top support plate 13 is welded to the top of the top connecting plate 12. The top support plate 13 is horizontally arranged and is used to directly contact and support the bottom of the upper module when the rotating fixture 1 is in a vertical state. Two upper vertical stiffeners 14 are welded at intervals to the lower surface of the top connecting plate 12. The two upper vertical stiffeners 14 are arranged at intervals along the length of the top connecting plate 12, and each upper vertical stiffener 14 extends downward perpendicularly to the top connecting plate 12. A transverse stiffener 15 is welded between the middle positions of the two upper vertical stiffeners 14. The transverse stiffener 15 is horizontally arranged and its two ends are welded and fixed to the inner sidewalls of the two upper vertical stiffeners 14, thereby connecting the two upper vertical stiffeners 14 into a whole structure and enhancing the overall rigidity of the rotating fixture 1. Bottom connecting plates 17 are welded to the bottom of the two upper vertical stiffening plates 14. The bottom connecting plates 17 are horizontally arranged and parallel to the top connecting plates 12. The bottom connecting plates 17 have four second fastening holes that penetrate their upper and lower surfaces. The positions and spacing of the four second fastening holes correspond one-to-one with the four first fastening holes on the top connecting plates 26.

[0026] A left ear plate 11 is welded to the outer wall of the upper vertical stiffener 14 on the left side. The left ear plate 11 has an opening for the hook of the chain hoist to pass through. A right ear plate 16 is welded to the outer wall of the upper vertical stiffener 14 on the right side. The right ear plate 16 has two openings: the upper opening is for the chain hoist hook to pass through; the lower opening is a bolt hole for the long bolt 5 to pass through. The right ear plate 16 corresponds in position to the main ear plate on the fixed base 2.

[0027] The rotatable connection between the rotating fixture 1 and the fixed base 2 is achieved through the long bolt 5. During assembly, the rotating fixture 1 is placed above the fixed base 2, aligning the lower opening of the right ear plate 16 with the U-shaped bolt hole on the right main ear plate of the fixed base 2. Then, the long bolt 5 is inserted from one side into the U-shaped bolt hole of the main ear plate and passes through the lower opening of the right ear plate 16. Finally, the nut is tightened at the end of the long bolt 5. At this point, the rotating fixture 1, using the long bolt 5 as its rotation axis, can rotate relative to the fixed base 2 between horizontal and vertical positions.

[0028] During the module hoisting and transportation process, the rotating fixture 1 is initially in a horizontal state, meaning that the rotating fixture 1 has rotated to a roughly horizontal position. At this point, the rotating fixture 1 leaves the top of the fixed base 2 and extends to one side, as shown below. Figure 2 As shown, the overall height of the marine fixture is relatively low, effectively preventing collisions with the modules during hoisting. Once the module is hoisted above the fixture and in place, the operator inserts the hooks of the hand-operated hoists through the openings in the left ear plate 11 and the upper opening in the right ear plate 16, respectively, and then simultaneously pulls both hand-operated hoists. Under the traction of the two hand-operated hoists, the rotating fixture 1 rotates upwards around the long bolt 5 as the pivot axis, as shown... Figure 3 As shown, with the continuous traction of the hand chain hoist, the rotating fixture 1 gradually rotates from a horizontal state to a vertical state, eventually reaching a vertical position. At this point, the rotating fixture 1 sits atop the fixed base 2, meaning the bottom connecting plate 17 and the top connecting plate 26 are in contact, as shown. Figure 4 As shown. At this time, the four second fastening holes on the bottom connecting plate 17 are aligned with the four first fastening holes on the top connecting plate 26. The operator inserts the four fastening bolts 4, which serve as fasteners, into the corresponding first and second fastening holes respectively, and tightens the nuts at the ends, thereby fixing the rotating fixture 1 and the fixed base 2 into one unit. At this time, the rotating fixture 1 is at a higher height and can reliably support the upper module.

[0029] After the rotating fixture 1 is rotated to a vertical position, a reinforcing diagonal brace 3 needs to be installed to further enhance the stability of the structure. The reinforcing diagonal brace 3 includes a right support plate 31, a second wing plate 32, two vertical wing plates 33, and a left support plate 34. The two vertical wing plates 33 are welded to the upper ends of the left and right sides of the base plate 22, respectively. The vertical wing plate 33 on the left side is located below the first wing plate 21 to support the first wing plate 21; the vertical wing plate 33 on the right side is located below the second wing plate 32 to support the second wing plate 32.

[0030] After rotating fixture 1 to a vertical position, first remove the long bolt 5. Then weld the right support plate 31 to the outside of the lower vertical stiffener 24 and the upper vertical stiffener 14 on the right side, with the height of the right support plate 31 higher than that of the diagonal brace 23. The length of the right-angled side of the diagonal brace 23 is not greater than the height of the corresponding lower vertical stiffener 24, while the length of the right support plate 31 is greater than the height of the lower vertical stiffener 24, and the length of the right support plate 31 is less than the sum of the heights of the lower vertical stiffener 24 and the upper vertical stiffener 14. Thus, when the right support plate 31 is installed in place, its upper end can abut against the outer wall of the upper vertical stiffener 14, and its lower end can abut against the outer wall of the lower vertical stiffener 24. Subsequently, the vertical right-angled edge of the right support plate 31 is welded and fixed to the outer walls of the upper vertical stiffening plate 14 and the lower vertical stiffening plate 24, respectively, and the lower right-angled edge of the right support plate 31 is welded and fixed to the upper surface of the base plate 22. In this way, the right support plate 31 supports and connects the rotating fixture 1 and the fixed base 2 as a whole from the right side.

[0031] Simultaneously, a left support plate 34 is welded to the top of the diagonal brace plate 23. The left support plate 34 is located on the left side, and its side is welded and fixed to the outer wall of the corresponding upper vertical stiffener plate 14. After assembly, the diagonal brace plate 23 and the left support plate 34 together provide support for the rotating fixture 1 and the fixed base 2 in a vertical state from the left side, while the right support plate 31 provides support for the rotating fixture 1 and the fixed base 2 from the right side. The combined effect of the support structures on both sides effectively enhances the lateral rigidity and anti-overturning ability of the rotating fixture 1 in a vertical support state, preventing structural tilting caused by ship swaying and vibration during sea transport.

[0032] When the module transportation is completed and the tooling needs to be dismantled, the operator first cuts and removes the welding points of the right support plate 31 and the left support plate 34, then removes the fastening bolts 4, hooks the hook of the hand chain hoist in the opposite direction, and slowly lowers and rotates the tooling 1 so that it rotates from the vertical position back to the horizontal position, thus completing the dismantling and recycling of the tooling.
