Description

Technical Field

[0001] The invention relates to an above-water construction platform, in particular to a construction platform device with a hanging basket. Background Art

[0002] During the construction, equipment installation and maintenance of offshore structures, it is often necessary to carry out construction around the monopile. Currently, there are usually two ways of offshore construction, namely, using conventional temporary multi-pile platforms and using offshore construction vessels. If a conventional temporary multi-pile platform is used, there are two conventional methods. One is to build a smaller temporary platform near the side of the monopile foundation pile. The temporary platform is supported by multiple steel pipe piles with smaller diameters. This method requires continuous piling and pulling piles and disassembling and assembling the platform to adjust the position of the temporary platform around the monopile foundation pile to meet the construction needs; the other is to use a very large temporary platform to surround the entire monopile foundation. This temporary platform is too large and technically and economically unreasonable. If an offshore construction vessel is used, a special offshore construction vessel (such as a DCM mixing ship) can be used, or the ship can carry construction equipment, that is, the onshore engineering machinery is installed and configured on a barge or a self-elevating platform ship. The special offshore construction vessel has high construction efficiency, but is generally large in size, the ship machinery construction period is tight and the equipment is expensive; the transformation of the ship generally requires the relevant equipment to be reasonably configured and fixed. Except for jack-up platforms, other ships need to continuously shift anchors during offshore construction. During offshore construction, they need to overcome the influence of environmental factors such as ocean currents, wave loads and sea breezes, and the construction quality is difficult to control. Jack-up platforms need to insert and remove pile legs to adjust their positions, which has low work efficiency and is technically and economically unreasonable.

[0003] In addition, during the construction of the single pile foundation, there will be a need for construction work at different elevations. In order to meet the needs of different working elevations, the existing offshore construction platform, especially when construction work is required at a lower elevation, has relatively complex temporary facilities and construction organization. Therefore, it is necessary to design a new construction platform device to overcome the problems existing in the above-mentioned existing construction methods. Summary of the invention

[0004] In view of the shortcomings of the prior art mentioned above, the technical problem to be solved by the present invention is to provide a construction platform device with a hanging basket, which uses a single pile foundation as support, can reduce the construction cost and time of the construction platform, improve the construction quality, and at the same time have different working platform elevations to enhance construction convenience and safety.

[0005] To achieve the above-mentioned purpose, the present invention provides a construction platform device with a hanging basket, which is installed on a single pile foundation and includes a connecting transition mechanism, an upper platform, and a hanging basket platform. The connecting transition mechanism is fixedly connected to the top of the single pile foundation in a detachable manner, the upper platform is fixed on the connecting transition mechanism, the hanging basket platform is located on the side of the single pile foundation, and the hanging basket platform is fixedly connected to the bottom of the upper platform by a suspension rod.

[0006] Furthermore, the hanging basket platform includes a hanging basket bottom frame, and a hanging basket panel or grid installed on the hanging basket bottom frame, and the hanging basket bottom frame includes a hanging basket main beam and a hanging basket secondary beam fixedly connected to each other.

[0007] Furthermore, a guide rail is provided on the hanging basket platform.

[0008] Further, the upper platform includes an upper bottom frame, and an upper panel or grid mounted on the upper bottom frame, and the upper bottom frame includes an upper main beam and an upper secondary beam fixedly connected to each other.

[0009] Furthermore, the upper platform is provided with an upper hole above the hanging basket platform.

[0010] Furthermore, a docking and boarding structure is provided on the side of the upper platform.

[0011] Furthermore, guardrails and wheel guard sills are provided on the sides of the upper platform.

[0012] Furthermore, the load-bearing system of the upper platform adopts a frame structure, a truss structure, a self-stressed arch structure, or a cable-stayed structure.

[0013] Furthermore, a fixing column is fixed to the bottom of the upper platform, a corbel is provided in the connection transition mechanism, and the fixing column is fixedly connected to the corbel.

[0014] As described above, the construction platform device with hanging basket according to the present invention has the following beneficial effects:

[0015] The construction platform device with hanging basket is directly installed on the monopile foundation, and the monopile foundation is used as the structural support. There is no need to set up a pile foundation separately, which simplifies the device and can reduce the construction cost and time of the construction platform; by setting the upper platform located on the top of the monopile foundation and the hanging basket platform located on the side of the monopile foundation, it can meet the needs of different construction elevations and improve the convenience and safety of construction; the connecting transition mechanism is installed on the monopile foundation in a detachable manner, and can be easily removed after the construction is completed, without hindering the subsequent use of the monopile foundation.

[0026] See also Figures 1 to 6 The present invention provides a construction platform device with a hanging basket, which is installed on a single pile foundation 1 and includes a connecting transition mechanism 4, an upper platform 2, and a hanging basket platform 3. The connecting transition mechanism 4 is fixedly connected to the top of the single pile foundation 1 in a detachable manner, the upper platform 2 is fixed on the connecting transition mechanism 4, the hanging basket platform 3 is located on the side of the single pile foundation 1, and the hanging basket platform 3 is connected to the bottom of the upper platform 2 by a suspension rod 5.

[0027] The construction platform device with a hanging basket involved in the present invention is directly installed on the monopile foundation 1, and there is no need to set up a pile foundation separately, which simplifies the device and can reduce the construction cost and time of the construction platform; by setting an upper platform 2 located on the top of the monopile foundation 1 and a hanging basket platform 3 located on the side of the monopile foundation 1, the upper platform 2 and the hanging basket platform 3 are used to install corresponding equipment 10 and personnel activities, which can meet the needs of different construction work elevations and improve the construction convenience and safety. The platform with the monopile foundation 1 as the structural support is limited by the design of the monopile foundation 1, and is usually located at a higher position, with a large distance to the seabed surface, which is not convenient for equipment construction. Therefore, the hanging basket platform 3 is used for construction close to the seabed surface; the connecting transition mechanism 4 is installed on the monopile foundation 1 in a detachable manner, and can be easily removed after the construction is completed, without hindering the subsequent use of the monopile foundation 1. The rotating construction platform of the present invention is stable and reliable, and can replace the original method of using offshore construction vessels or temporary construction platforms. It can reduce the adverse effects of the marine environment such as tides, waves and currents, improve the continuity of construction operations, save construction time and costs, and avoid the ship engine being shaken by waves and hitting the single pile foundation 1 when the construction space is small, thereby improving the construction positioning accuracy and ensuring the construction quality.

[0028] See also Figure 1 to Figure 2 The present invention is further described below with a specific embodiment:

[0029] In this embodiment, see Figure 1 , Figure 3 and Figure 4 The hanging basket platform 3 includes a hanging basket bottom frame, and a hanging basket panel or grille 3c installed on the hanging basket bottom frame. The bottom frame specifically includes a hanging basket main beam 3a and a hanging basket secondary beam 3b that are fixedly connected to each other. The hanging basket platform 3 is square and has a frame composed of the hanging basket main beam 3a on its outer periphery. In addition, hanging basket holes 3d are provided at appropriate positions of the hanging basket platform 3 as needed to facilitate construction operations. In this embodiment, see Figure 1 Figure 2 The upper platform 2 includes an upper bottom frame and an upper panel or grid 2c installed on the upper bottom frame. The upper bottom frame includes an upper main beam 2a and an upper secondary beam 2b that are fixed to each other. The hanging basket platform 3 is square and has a frame composed of the upper main beam 2a on its outer periphery. The upper platform 2 is provided with an upper hole 2d above the hanging basket platform 3 to facilitate the staff and equipment to enter the hanging basket platform 3. The upper platform 2 can also be provided with an upper hole 2d at other suitable positions as needed.

[0030] In this embodiment, see Figure 1 Figure 2 The load-bearing system of the upper platform 2 is composed of an upper bottom frame and a vertical reinforcement structure fixed on the upper bottom frame. The load-bearing system can specifically adopt a frame structure, a truss structure, a self-stressed arch structure, or a cable-stayed structure, etc., to enhance the strength and rigidity of the entire upper platform 2.

[0031] In this embodiment, see Figure 1 and Figure 2 As a preferred design, the upper platform 2 is provided with guardrails 8 and wheel guards 7 at the edge for safety protection. In addition, a berthing and boarding structure 9 is also provided at the side of the upper platform 2, which is generally drooped downward to facilitate people to get on and off the platform.

[0032] In this embodiment, both the upper platform 2 and the hanging basket platform 3 can be equipped with life-saving and escape facilities, and necessary sunshade, rainproof and windproof facilities are provided. At the same time, the upper platform 2 is also provided with basic lightning protection facilities.

[0033] In this embodiment, a track beam 13 is provided on the hanging basket platform 3, and a guide rail 14 is installed on the track beam 13. Brackets, embedded bolts, etc. are also provided on the upper platform 2 and the hanging basket platform 3. The guide rails 14, brackets, embedded bolts and other structures are used for the installation and movement of silos 11 such as oil tanks, water tanks, cement silos, etc., and for the installation and removal of equipment 10 such as diesel generators, air compressors, mud pumps, high-pressure grouting machines, cement mixing pile machines, small cranes, small drilling rigs, etc. The above silos 11 and equipment 10 can be hoisted to the upper platform 2 and the hanging basket platform 3 by a crane ship, or temporarily fixed on the upper platform 2 and the hanging basket platform 3 in advance, and then hoisted as a whole.

[0034] In this embodiment, see Figure 1 and Figure 2 As a preferred design, the connecting transition mechanism 4 has a rotating function, including a first connecting sleeve 4a, a second connecting sleeve 4b, and a rotating structure 4c. The first connecting sleeve 4a is fixedly connected to the top of the single pile foundation 1, and the second connecting sleeve 4b is installed on the first connecting sleeve 4a through the rotating structure 4c. The first connecting sleeve 4a and the second connecting sleeve 4b are both coaxial with the single pile foundation 1. The upper platform 2 is fixedly connected to the second connecting sleeve 4b, so that the rotation of the second connecting sleeve 4b can drive the upper platform 2 and the hanging basket platform 3 to rotate, so that the upper platform 2 and the hanging basket platform 3 can be rotated to the construction position as needed, and can cover a large construction range when the upper platform 2 is not large, thereby reducing the structural size of the upper platform 2 and the hanging basket platform 3. At this time, as needed, the square upper platform 2 can be extended from the single pile foundation 1 on both sides, see Figure 1 and Figure 2 As shown, it is also possible to extend out of the monopile foundation 1 on one side (the side on which the hanging basket platform 3 is suspended), see Figure 6 Among them, the slewing structure 4c is generally composed of two relatively rotatable steel races, which can simultaneously bear axial force, radial force and overturning moment. The slewing bearing structure can be single-row four-point contact ball type, single-row cross roller type, double-row or double-row ball type, three-row roller type, ball-column combined type, etc.

[0035] In this embodiment, as a preferred design, the connecting transition mechanism 4 has a bracket 4e, see Figure 5 There are multiple corbels 4e, which are reasonably distributed inside and outside the second connecting sleeve 4b, and a support rod 4d is fixedly connected between the corbel 4e and the second connecting sleeve 4b to further stabilize the corbel 4e. A fixing column 6 is fixedly provided on the upper platform 2. The fixing column 6 generally extends out of the bottom of the upper platform 2. The fixing column 6 can be specifically fixedly connected to the upper main beam 2a. The corbel 4e has a flange, and the bottom of the fixing column 6 also has a flange. The fixing column 6 is fixedly connected to the corbel 4e by bolts and flanges.

[0036] In this embodiment, the connecting transition mechanism 4 is fixedly connected to the single pile foundation 1 by bolts. Specifically, the single pile foundation 1 has a flange on the top, and a corresponding flange is provided at the bottom of the connecting transition mechanism 4. The two flanges are fixedly connected by bolts, which facilitates the construction of the construction platform device with a hanging basket on the single pile foundation 1. The construction platform device with a hanging basket can also be flexibly removed from the single pile foundation 1 and can be reused without affecting the subsequent use of the single pile foundation 1.

[0037] As can be seen from the above, the construction platform device with hanging basket of the present invention uses the top of the single pile foundation 1 as the supporting foundation. As the diameter of the single pile of the offshore wind power foundation increases, the area of ​​the pile top increases, and it has sufficient rigidity. The bearing capacity of the single pile is enhanced, and the rotating platform can be stably and reliably supported. Through the construction platform device with hanging basket, the construction around the single pile foundation 1 can be effectively completed, such as the reinforcement of the foundation around the pile (such as the replacement method, the high-pressure rotary spraying method, and the cement mixing method). The construction platform device with hanging basket can replace the original method of using offshore construction ships or conventional temporary multi-pile platforms, reduce the adverse effects of the marine environment such as tide waves and water currents, improve the continuity of construction, save ship time and costs, avoid the ship engine being shaken by waves and hitting the single pile foundation 1 when the construction space is small, improve the construction positioning accuracy, and ensure the construction quality. The construction platform device with hanging basket has platforms with different working elevations, which brings convenience to construction and has practical engineering significance.

[0038] The construction platform device with hanging basket of the present invention can also be used for the construction of anti-scour facilities around piles (layout of sand blankets, stone throwing around piles, artificial blocks thrown around piles, solidified soil anti-scour layers), installation of auxiliary components, repair of anti-corrosion coatings, etc., and can also be used as a temporary survey, observation, and detection platform.

[0039] The construction platform device with hanging basket of the present invention can be used as an offshore construction platform and can also be set on a single column foundation in lakes, rivers and other waters as an aquatic construction platform based on the same or similar principles.

[0040] In summary, the present invention effectively overcomes various shortcomings in the prior art and has high industrial utilization value.

[0041] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
