Description

Technical Field

[0001] This utility model relates to the field of transportation technology, specifically a double-layer support for wind power steel pipe piles. Background Technology

[0002] Offshore wind turbine steel pipe piles are an important component of offshore wind turbine units. As global offshore wind power develops towards deep and deep seas, the size and weight of the foundation structure supporting the wind turbine have increased significantly. Ships face dynamic loads such as waves, wind loads, and inertial forces during navigation, and traditional bulk carriers cannot meet the needs of ultra-large components.

[0003] Therefore, there is an urgent need to design specialized marine support structures for efficient transportation. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a double-layer support for wind power steel pipe piles, which is easy to operate and has a stable and reliable structure.

[0005] The first technical solution of this utility model is as follows:

[0006] A double-layer support for wind turbine steel pipe piles includes a bottom support, an upper support, and connectors.

[0007] The bottom support is fixed to the deck, and the upper support is located above the bottom support and connected by the connector;

[0008] The bottom support has multiple bottom accommodating areas, and the upper support has multiple upper accommodating areas. The bottom accommodating areas and the upper accommodating areas are arranged alternately, and the number of bottom accommodating areas is one more than the number of upper accommodating areas.

[0009] Furthermore, the bottom support includes a bottom beam and multiple pairs of triangular limiting blocks. The bottom beam is arranged horizontally, and the multiple pairs of triangular limiting blocks are spaced apart on the bottom beam. Each triangular limiting block has an arc-shaped slope, and each pair of triangular limiting blocks is arranged opposite to each other to form the bottom receiving area.

[0010] Furthermore, the bottom beam includes multiple I-beams and multiple support plates, with the multiple I-beams being spliced ​​together in sequence, and multiple support plates being spaced apart on both sides of the waist of the I-beams.

[0011] Furthermore, the bottom support also includes multiple welded components, which are spaced apart on both sides of the bottom beam, and the connecting components connect the bottom beam and the deck by welding.

[0012] Furthermore, the bottom support also includes multiple adjusting components disposed between the bottom beam and the deck.

[0013] Furthermore, the bottom of the upper support has multiple arc-shaped limiting surfaces and the top surface has multiple arc-shaped supporting surfaces. The arc-shaped limiting surfaces and the arc-shaped supporting surfaces are arranged alternately, and the number of arc-shaped limiting surfaces is one more than the number of arc-shaped supporting surfaces.

[0014] Furthermore, the connector includes a sleeve and a pin. The sleeve is fixed to the top surface of the bottom support and located between the two bottom receiving areas. The pin is fixed to the bottom surface of the upper support. The length of the sleeve and the pin is greater than the radius of the steel pipe pile and less than the diameter of the steel pipe pile. The sleeve is fitted onto the pin.

[0015] Furthermore, it also includes a laser positioning device, which is disposed on one side of the bottom support.

[0016] Furthermore, it also includes multiple binding steel bars, which are respectively fixed to both sides of the bottom support and the upper support.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] First, the steel pipe piles are placed one by one on the corresponding bottom receiving area of ​​the bottom support. After the bottom support is full, the upper support is installed through the connector. Then, the steel pipe piles are placed on the corresponding upper receiving area of ​​the upper support. This realizes the loading of steel pipe piles for ship transportation. The operation is convenient and the structure is stable and reliable. Attached Figure Description

[0027] like Figure 1-2 As shown, this embodiment provides a double-layer support for a wind power steel pipe pile 6. Multiple double-layer supports are axially spaced on the deck of a transport vessel to provide multiple points of limiting and support for the steel pipe pile 6. The double-layer support includes a bottom support 1, an upper support 2, and a connector 3.

[0028] The bottom support 1 is fixed to the deck, and the upper support 2 is located above the bottom support 1 and is connected by the connector 3;

[0029] The bottom support 1 has multiple bottom receiving areas, and the upper support 2 has multiple upper receiving areas. Each of the above receiving areas provides a limit and support for a steel pipe pile 6. The bottom receiving areas and the upper receiving areas are staggered, and the number of bottom receiving areas is one more than the number of upper receiving areas, so that the upper and lower steel pipe piles 6 are stacked alternately.

[0030] Specifically, the steel pipe piles 6 are first placed one by one on the corresponding bottom receiving area of ​​the bottom support 1. After the bottom support 1 is full, the upper support 2 is installed through the connector 3. Then the steel pipe piles 6 are placed on the corresponding upper receiving area of ​​the upper support 2. This realizes the transshipment of the steel pipe piles 6 by ship. The operation is convenient and the structure is stable and reliable.

[0031] like Figure 3 As shown, in a preferred embodiment, the bottom support 1 includes a bottom beam 11 and multiple pairs of triangular limiting blocks 12. The bottom beam 11 is arranged laterally, and the multiple pairs of triangular limiting blocks 12 are spaced apart on the bottom beam 11. Each triangular limiting block 12 has an arc-shaped slope. Each pair of triangular limiting blocks 12 is arranged opposite to each other to form the bottom receiving area, so as to achieve lateral limiting of the steel pipe pile 6.

[0032] like Figure 3 As shown, preferably, the bottom beam 11 includes multiple I-beams and multiple support plates. The multiple I-beams are spliced ​​together in sequence. The length of the I-beam is greater than the diameter of the steel pipe pile 6. Each pair of triangular limiting blocks 12 is set on one of the I-beams. Multiple support plates are provided at intervals on both sides of the waist of the I-beam to improve the rigidity of the I-beam.

[0033] like Figure 3 As shown, the bottom support 1 further includes multiple welded parts 13 and multiple connectors 3 spaced apart on both sides of the bottom beam 11. The connectors 3 connect the bottom beam 11 and the deck by welding to fix the bottom beam 11 to the deck.

[0034] like Figure 3 As shown, preferably, the welded component 13 includes a first connecting plate and two second connecting plates. The first connecting plate has a notch that is adapted to the bottom plate of the I-beam, so that one side of the first connecting plate is located inside the I-beam and contacts the bottom plate of the I-beam for welding, and the other side abuts against the deck. The second connecting plates are horizontally arranged on both sides of the protruding portion of the first connecting plate and are connected to the first connecting plate and the deck by welding to fix the bottom support 1.

[0035] Due to long-term use, the ship's deck may develop dents, affecting the installation and use of the bottom support 1. Therefore, as... Figure 3 As shown, the bottom support 1 also includes a plurality of adjusting members 14, which are disposed between the bottom beam 11 and the deck. The adjusting members 14 are used to assist the bottom beam 11 in adapting to the recessed area of ​​the deck so as to meet the requirement of the bottom beam 11 being horizontally positioned.

[0036] Specifically, the adjusting component 14 includes a nut and a bolt. Through holes are spaced apart on the base plate of the I-beam. The nut is welded to the through holes. The bolt and the nut cooperate so that the bolt passes through the through holes and abuts against the deck. This is to deal with the possibility of unevenness on the deck, so that the I-beam remains level and can have sufficient contact support with the deck.

[0037] like Figure 4 As shown, in a preferred embodiment, the upper support 2 has multiple arc-shaped limiting surfaces 211 at its bottom and multiple arc-shaped supporting surfaces 212 on its top surface. The arc-shaped limiting surfaces 211 and the arc-shaped supporting surfaces 212 are staggered, and the number of arc-shaped limiting surfaces 211 is one more than the number of arc-shaped supporting surfaces 212. The arc-shaped limiting surfaces 211 are fitted into the top of the steel pipe pile 6, achieving horizontal limiting under the action of gravity. The arc-shaped supporting surfaces 212 are used to provide support and limiting for the upper steel pipe pile 6 to form the upper receiving area.

[0038] Specifically, the upper support 2 is spliced ​​together from multiple supporting steels 21, the arc-shaped support surface 212 is located in the middle of its top surface, and the arc-shaped limiting surface 211 is on both sides of its ground.

[0039] like Figure 2-4 As shown, in a preferred embodiment, the connector 3 includes a sleeve 31 and a pin 32. The sleeve 31 is fixed to the top surface of the bottom support 1 and located between the two bottom receiving areas. The pin 32 is fixed to the bottom surface of the upper support 2. The length of the sleeve 31 and the pin 32 is greater than the radius of the steel pipe pile 6 and less than the diameter of the steel pipe pile 6. The sleeve 31 is fitted onto the pin 32 to achieve the docking of the upper support 2 and the bottom support 1, thereby achieving axial horizontal limiting. With the cooperation of the first arc-shaped limiting surface 211 and the steel pipe pile 6 located in the first layer, the lower steel pipe pile 6 can provide lateral horizontal limiting and support for the upper support 2 to support the upper steel pipe pile 6 (the steel pipe pile 6 itself is a supporting structural component because the rigidity of the lower steel pipe pile 6 is sufficient to support the weight of the upper steel pipe pile 6).

[0040] like Figure 1-3 As shown, as a preferred embodiment, the double-layer bracket also includes a laser positioning device 4, which is disposed on the lateral side of the bottom bracket 1 and is used for axial positioning when multiple double-layer brackets are installed together.

[0041] Specifically, the laser positioning device 4 includes a laser emitter and a laser receiver, which are respectively set on double-layer supports arranged on both sides of the axis; the double-layer support located in the middle position is also provided with a transparent target. The laser emitted by the laser emitter passes through the transparent target and finally lands on the laser receiver, ensuring that multiple double-layer supports are on the same axis.

[0042] like Figure 3-4 As shown, as a preferred embodiment, it also includes multiple binding steel bars 5, which are respectively fixed on both sides of the bottom support 1 and the upper support 2 for binding when installing cotton pads.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
