Description

Technical Field

[0001] This utility model relates to the field of buoyancy equipment technology for marine engineering, and in particular to a buoyancy operation platform for marine engineering. Background Technology

[0002] When operating on offshore platforms, such as during transportation or hoisting operations, it is necessary to ensure the stability of the buoyancy support platform. However, existing offshore platforms cannot actively adjust their buoyancy after a change in their center of gravity. For example, CN218877532U, published on April 18, 2023, discloses a mobile offshore operation support platform, including a float, a lower construction platform mounted on the float, and an upper construction platform supported above the lower construction platform by columns. The upper construction platform has a hoisting window, which serves as a cargo passage between the upper and lower construction platforms. A ladder is provided between the upper and lower construction platforms, serving as a personnel passage. A trolley track is installed at the bottom of the upper construction platform, and a trolley for hoisting cargo from the lower construction platform is mounted on the trolley. A crane support frame is provided on the upper construction platform, and a crane is mounted on the crane support frame. Its advantages are: it solves the needs of offshore construction workers for accommodation and large-area rainproof construction sites, reduces the need for shore-based support for offshore construction, and greatly improves the construction efficiency of offshore projects; its disadvantages are: if the platform's center of gravity changes during hoisting, it will cause the platform to tilt, and the platform cannot actively adjust its balance.

[0003] To address the issue of platform tilting caused by changes in the platform's center of gravity, CN116829450A, published on September 29, 2023, discloses a device for installing equipment on offshore platforms. This device includes a hull, with a hull plate fixedly installed on the top. Two symmetrically arranged telescopic grooves are formed on both sides of the hull plate, and fixed plates are slidably connected within these grooves. A threaded rod is threaded between the two fixed plates, and a support rod is slidably connected to the fixed plate. A floating air cushion is fixedly installed at the bottom end of the support rod. A placement cavity is formed on the hull plate, and a motor is fixedly installed on the inner wall of one side of the placement cavity. While this device can support the hull and prevent tilting by extending the floating air cushion, its drawback is that the two independent floating air cushions are located on opposite sides of the hull. During use, only both floating air cushions can be extended simultaneously; it cannot provide buoyancy support to only one side or corner individually. Utility Model Content

[0004] The technical problem to be solved by this utility model is to solve the problems existing in the background art and provide a marine engineering buoyancy operation platform. By sliding and installing multiple telescopic floats between the float and the operation platform, each telescopic float is driven to extend and retract by an individual telescopic device, thereby enabling buoyancy support for one side or one corner of the platform independently.

[0005] To achieve the above-mentioned technical features, the purpose of this utility model is as follows: A marine engineering buoyancy operation platform includes a float, support columns, and an operation platform. Multiple support columns are fixedly installed on the left and right sides of the top of the float, and the operation platform is fixedly installed on the support columns. Telescopic floats are slidably installed between the float and the operation platform, and between two adjacent support columns on the same side. One end of the telescopic device is connected to the operation platform, and the other end is connected to the telescopic float to drive the telescopic float to extend and retract.

[0006] Four support columns are fixedly installed on the left and right sides of the top of the float, and telescopic floats are installed between the two support columns at the front end and between the two support columns at the rear end; the telescopic floats are located on the left and right sides of the float.

[0007] The telescopic float includes a sliding chamber and a buoyancy chamber. The buoyancy chamber is connected to one end of the sliding chamber. The height of the buoyancy chamber is greater than the height of the sliding chamber. The upper end of the buoyancy chamber is flush with the sliding chamber, and the lower end of the buoyancy chamber extends downward. The sliding chamber is located at the top of the float, and the buoyancy chamber is located on the outside of the float.

[0008] A guide assembly is fixedly installed on the float at the position of the corresponding telescopic float, and the telescopic float slides along the guide assembly.

[0009] The guide assembly is a portal frame or two side plates. The telescopic float slides within the portal frame or between the two side plates. One end of the telescopic device is connected to the float, and the other end is connected to the end of the telescopic float located in the middle of the float.

[0010] One end of the telescopic device is hinged to the float via a fixed hinge support, and the other end is also hinged to the telescopic float via a fixed hinge support.

[0011] The guide assembly includes two L-shaped plates arranged opposite each other. A telescopic float slides between the two L-shaped plates. A connecting plate is fixedly installed on the top of the two L-shaped plates on one side of the support column. A traction plate is fixedly installed on one end of the telescopic float located in the middle of the float. One end of the telescopic device is connected to the connecting plate, and the other end is connected to the traction plate.

[0012] One end of the telescopic device is connected to the connecting plate via a fixed hinge support structure, and the other end is connected to the traction plate via a fixed hinge support structure.

[0013] A first sliding plate is fixedly installed on the side of the guide assembly that contacts the telescopic float, and a second sliding plate is fixedly installed on the top of the float at the position where it contacts the telescopic float.

[0014] The float has blocks fixed to its inner and outer sides on the lower side of the telescopic float, and the second slide plate is embedded in the space enclosed by the guide assembly and the blocks. The first slide plate is provided with countersunk bolt holes, and the guide assembly is provided with threaded holes. The threaded end of the countersunk screw passes through the countersunk bolt hole and is then screwed into the threaded hole for fixation.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0034] Example 1:

[0035] See Figure 1-8A marine engineering buoyancy platform includes a float 10, support columns 20, and a working platform 30. Multiple support columns 20 are welded and installed on the left and right sides of the top of the float 10. The working platform 30 is fixedly installed on the support columns 20. Telescopic floats 50 are slidably installed between the float 10 and the working platform 30, and between two adjacent support columns 20 on the same side. One end of a telescopic device 60 is connected to the working platform, and the other end is connected to the telescopic float 50 to drive the telescopic float 50 to extend and retract. By slidably installing multiple telescopic floats 50 between the float 10 and the working platform 30, each telescopic float 50 is driven to extend and retract by an individual telescopic device 60, thereby enabling individual buoyancy support for one side or one corner of the platform.

[0036] In this embodiment, the float 10 can adopt the float structure described in CN218877532U or the hull structure described in CN116829450A. The support column 20 adopts a hollow tubular structure. See also Figure 1 The floating body 10 and the working platform 30 are both in the overhead space 40, which is used to install the telescopic floating block 50.

[0037] In this embodiment, see Figure 3 Four support columns 20 are fixedly installed on the left and right sides of the top of the float 10. Telescopic floats 50 are installed between the two support columns 20 at the front end and between the two support columns 20 at the rear end. The telescopic floats 50 are located on the left and right sides of the float 10.

[0038] See Figure 5 The telescopic float 50 includes a sliding chamber 51 and a buoyancy chamber 52. The buoyancy chamber 52 is connected to one end of the sliding chamber 51, and its height is greater than that of the sliding chamber 51. The upper end of the buoyancy chamber 52 is flush with the sliding chamber 51, and the lower end of the buoyancy chamber 52 extends downward. The sliding chamber 51 is located at the top of the float 10, and the buoyancy chamber 52 is located on the outside of the float 10. In this embodiment, the telescopic float 50 is a hollow structure formed by welding metal plates.

[0039] In this embodiment, the telescopic device 60 is a hydraulic cylinder or a pneumatic cylinder.

[0040] To facilitate towing, at least one towing ring 31 is welded onto the working platform.

[0041] Example 2:

[0042] Based on Embodiment 1, a guide component is fixedly installed on the float 10 at the position corresponding to the telescopic float 50. The telescopic float 50 slides along the guide component to extend and retract, thereby improving the stability of the telescopic float 50's extension and retraction.

[0043] In this embodiment, see Figure 8The guide component is a gate-shaped frame or two side plates 17. The telescopic float 50 slides within the gate-shaped frame or between the two side plates 17. One end of the telescopic device 60 is connected to the float 10, and the other end is connected to the end of the telescopic float 50 located in the middle of the float 10.

[0044] When the guide assembly is a portal frame structure, the portal frame structure is fixedly installed on the float 10, and the telescopic float 50 slides within the portal frame structure. When the guide assembly consists of two side plates 17, the lower end of the side plates 17 is fixedly installed to the float 10, and the upper end is fixedly installed to the work platform 30, and the telescopic float 50 slides between the two side plates 17. In this embodiment, as... Figure 8 As shown, when the width of the float 10 is sufficient, the telescopic device 60 is installed between the telescopic floats 50 on both sides.

[0045] In this embodiment, one end of the telescopic device 60 is hinged to the float 10 via a fixed hinge support, and the other end is also hinged to the telescopic float 50 via a fixed hinge support. Specifically, a hydraulic CB double-ear seat is fixedly installed on the top of the float 10 by welding or bolts. The cylinder end of the telescopic device 60 has a hinge joint, which is hinged to the hydraulic CB double-ear seat via a pin 15. The end of the telescopic float 50 near the telescopic device 60 is also fixedly installed with a hydraulic CB double-ear seat by welding or bolts. A cylinder lug is installed on the piston rod end of the telescopic device 60, and the cylinder lug is hinged to the hydraulic CB double-ear seat on the telescopic float 50 via a pin 15.

[0046] Example 3:

[0047] The difference between this embodiment and embodiment 2 is that, see Figure 4 The guide assembly includes two L-shaped plates 11, which are arranged opposite to each other. A telescopic float 50 slides between the two L-shaped plates 11. A connecting plate 12 is fixedly installed on the top of the two L-shaped plates 11 at one side of the support column 20 by welding or bolting. (See attached image.) Figure 5 A traction plate 53 is fixedly installed at one end of the telescopic float 50 located in the middle of the float 10. One end of the telescopic device 60 is connected to the connecting plate 12, and the other end is connected to the traction plate 53. Through the above structure, the telescopic device 60 is positioned above the telescopic float 50, combined with... Figure 3 This is suitable for applications where the width of the float is relatively narrow.

[0048] In this embodiment, see Figure 5 , 6 One end of the telescopic device 60 is connected to the connecting plate 12 via a fixed hinge support structure 14, and the other end is connected to the traction plate 53 via the same fixed hinge support structure 14. The fixed hinge support structure 14 can be a hydraulic CB double-ear seat structure, and the installation method of the telescopic device 60 is the same as the hinge installation method in Embodiment 2.

[0049] Figure 5 The image shows the telescopic float in the retracted state, at which point the telescopic device 60 extends.

[0050] Figure 6 The image shows the telescopic float in the extended state, at which time the telescopic device 60 is retracted.

[0051] Example 4:

[0052] Based on Embodiment 2 or Embodiment 3, in order to improve the sliding flexibility of the telescopic float 50, see [reference needed]. Figure 4 , 5 6. A first sliding plate 13 is fixedly installed on the side of the guide assembly that contacts the telescopic float 50, and a second sliding plate 16 is fixedly installed on the top of the float 10 at the position where it contacts the telescopic float 50.

[0053] In this embodiment, both the first sliding plate 13 and the second sliding plate 16 are self-lubricating sliding plates.

[0054] Specifically, see Figure 5 On the float 10, blocks 18 are fixedly attached to both the inner and outer sides below the telescopic float 50. The second slide plate 16 is embedded in the space enclosed by the guide assembly and the blocks 18. After the blocks 18 are welded to the inner and outer sides below the telescopic float 50 on the float 10, a limiting groove is formed between the blocks 18 on both sides and the guide assemblies on both sides, thereby limiting the second slide plate 16 to be embedded in this limiting groove.

[0055] See also Figure 4 , and then combine Figure 6 , 7 The first slide plate 13 is provided with a countersunk bolt hole 131, and the guide assembly is provided with a threaded hole 111. The threaded end of the countersunk screw 132 passes through the countersunk bolt hole 131 and is then screwed into the threaded hole 111 for fixation, thereby installing and fixing the first slide plate 13 onto the guide assembly.

[0056] The working principle or working process of this utility model:

[0057] When using, please refer to Figure 3 When the left side of the float 10 tilts towards the water surface, the two telescopic floats 50 on the left side extend through the telescopic device 60 to provide buoyancy support for the left side of the float 10; when the right side of the float 10 tilts towards the water surface, the two telescopic floats 50 on the right side extend through the telescopic device 60 to provide buoyancy support for the left side of the float 10.

[0058] When the front side of the float 10 tilts towards the water surface, the two telescopic floats 50 on the front side extend through the telescopic device 60 to provide buoyancy support for the front side of the float 10; when the rear side of the float 10 tilts towards the water surface, the two telescopic floats 50 on the rear side extend through the telescopic device 60 to provide buoyancy support for the rear side of the float 10.

[0059] When the left front side of the float 10 tilts towards the water surface, the telescopic float 50 on the left front side extends through the telescopic device 60 to provide buoyancy support for the left front side of the float 10; in this way, buoyancy support can be provided separately for each corner of the float 10.

[0060] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention.
