Description

Technical Field

[0001] The utility model discloses a connection structure between a ball bearing and a pile foundation, belonging to the technical field of connection. Background Art

[0002] Within the vast field of renewable energy, offshore photovoltaic projects are attracting significant attention for their high output and minimal land occupation. These projects typically involve constructing a large offshore pile foundation cluster, upon which the superstructure is installed to complete the layout of the photovoltaic panels. The superstructure is typically prefabricated onshore to leverage the stable environment and advanced manufacturing facilities, ensuring precision and quality. The prefabricated superstructure is then transported by sea to the offshore pile cluster, where it is hoisted above the piles using lifting equipment and secured to the piles.

[0003] However, the complexity of the offshore environment presents numerous challenges for the construction of offshore photovoltaic projects. Wind and waves are particularly significant. High winds and rough seas make the transportation and installation of topside supports particularly difficult. Currently, the industry typically uses welding or screw fastening to secure the topside supports to the transport device or pile foundation. While these methods can achieve a certain degree of support stability, they have several drawbacks.

[0004] First, fixing methods like welding or screw fastening are cumbersome and require extensive on-site operations in offshore environments. This not only increases the workload for construction workers but also poses safety risks due to the unpredictable offshore environment. Second, these fixing methods take a long time to install, significantly impacting construction efficiency. Within the limited offshore construction window, the lengthy installation process means fewer brackets can be installed, potentially impacting the overall project schedule and profitability.

[0031] In the following description, specific details such as specific system structures and technologies are provided for purposes of illustration, not limitation, to facilitate a thorough understanding of the embodiments of the present invention. However, it will be apparent to those skilled in the art that the present invention can be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems and devices are omitted to avoid obscuring the description of the present invention with unnecessary detail.

[0032] The following is combined with Figure 1-4 The preferred technical solutions of the present invention are further described with reference to the accompanying drawings and embodiments.

[0033] A connection structure between a ball bearing and a pile foundation, comprising a ball bearing 1, a pile foundation 2, a bearing flange end plate 3, a pile foundation flange end plate 4, and at least two sets of connection components; the bearing flange end plate 3 is fixed to the lower end of the ball bearing 1; the pile foundation flange end plate 4 is fixed to the upper end of the pile foundation 2; each set of connection components includes an upper connecting piece and a lower connecting piece, which are respectively arranged on the bearing flange end plate 3 and the pile foundation flange end plate 4, and are connected by bolts.

[0034] Specifically, such as Figure 2 As shown, a hoisting plate 11 for hoisting is fixed on the ball support 1, and a through hole is provided on the hoisting plate 11; Figure 2 and Figure 4 As shown, the ball support 1 is connected to the support structure of the upper space support, and the support structure is specifically a plurality of support legs 12 of the upper space support.

[0035] The present invention does not limit the number of connection components, and those skilled in the art can set it according to actual conditions. In this embodiment, four groups of connection components are included and evenly distributed on the flange end plate. Figure 1 As shown, the connection structure further includes a ball bearing support tube 5 ; one end of the ball bearing support tube 5 is connected to the ball bearing 1 , and the other end is connected to the bearing flange end plate 3 .

[0036] Specifically, in this embodiment, the ball bearing support tube 5 , the bearing flange end plate 3 and the ball bearing 1 are integrally formed.

[0037] Furthermore, the upper connecting part includes an upper connecting rib 6 and an upper connecting plate 7; one end of the upper connecting rib 6 is vertically fixed to the side surface of the support flange end plate 3 close to the ball support 1, and the other end extends out of the edge of the support flange end plate 3; the upper connecting plate 7 is horizontally arranged and fixedly connected to the protruding end of the upper connecting rib 6.

[0038] The present invention does not limit whether the upper connecting rib 6 is connected to the ball bearing support tube 5 . In another embodiment, the upper connecting rib 6 is also connected to the ball bearing support tube 5 .

[0039] Furthermore, the lower connecting member includes a lower connecting rib 8 and a lower connecting plate 9; the lower connecting rib 8 is vertically arranged on the side wall of the pile foundation 2; the lower connecting plate 9 is horizontally arranged and fixedly connected to the side of the lower connecting rib 8 close to the pile foundation flange end plate 4.

[0040] Furthermore, a preset gap is provided between the upper connecting plate 7 and the support flange end plate 3 in the horizontal direction.

[0041] Furthermore, the upper connecting plate 7 is provided with a plurality of bolt holes; and the lower connecting plate 9 is correspondingly provided with a plurality of through-hole slots.

[0042] Specifically, refer to Figure 1 and3 As shown, the upper connecting plate 7 and the support flange end plate 3 have a preset gap in the horizontal direction, so that the ball support 1 driven by the upper connecting plate 7 and the pile foundation 2 have a certain horizontal displacement freedom, thereby realizing a fixed hinged connection between the ball support 1 and the pile foundation 2; when the connection structure is subjected to horizontal wind loads, the stress generated by the wind can be dispersed to the entire structure through the relative horizontal displacement between the ball support 1 and the pile foundation 2; at the same time, during the horizontal displacement process, part of the energy generated by the wind is absorbed and dissipated; the structure also has a certain degree of adaptability, which can adapt to wind conditions of different directions and sizes, reducing the risk of structural damage; and can reduce the impact of wind-induced vibration on the connection structure. Wind-induced vibration refers to the vibration generated by the structure under the action of wind. Vibration may cause structural fatigue and damage. The horizontal displacement freedom allowed by the fixed intersection connection can reduce the amplitude and frequency of the vibration; in summary, the fixed intersection connection greatly enhances the wind load resistance of the connection structure.

[0043] For further reference, Figure 2 As shown, the plane size of the support flange end plate 3 is smaller than the plane size of the pile foundation flange end plate 4.

[0044] Furthermore, it also includes a guide cone 13 ; the guide cone 13 is connected to the ball bearing support tube 5 and is used to be inserted into the pile foundation 2 .

[0045] Specifically, when the connection structure is fixed in place, in order to prevent deviation before the bolts are tightened, a guide cone 13 is provided on the upper structure connected to the ball support 1. The diameter of the guide cone 13 is slightly smaller than the diameter of the steel pipe of the pile foundation 2.

[0046] Further, such as Figure 1 As shown, the connection structure further includes a plurality of first ribs 10 ; the plurality of first ribs 10 are vertically arranged around the side wall of the ball bearing support tube 5 and are fixedly connected to the bearing flange end plate 3 .

[0047] The operation process of this connection structure during installation is as follows:

[0048] By passing the hook of the lifting device through the Figure 2 The hoisting plate 11 on the top of the ball bearing 1 is shown, and then the upper space bracket fixedly connected to the ball bearing 1 is hoisted above the pile foundation 2, and the guide cone 13 is inserted into the steel pipe of the pile foundation 2, so that the bearing flange end plate 3 and the pile foundation flange end plate 4 fit tightly and are basically in a concentric position, so that the upper connecting plate 7 and the lower connecting plate 9 fit together, and then the upper connecting plate 7 and the lower connecting plate 9 are connected by bolts to achieve a fixed connection between the ball bearing 1 and the pile foundation 2.

[0049] The connection structure of the present invention is simple in structure and easy to implement during the connection and fixing process, which reduces the difficulty of construction workers. It can quickly achieve long-term fixed connection between the upper space support and the pile foundation 2, as well as anchoring, restraining and removal during the sea transportation stage, avoiding cumbersome fixing measures such as welding or screw fastening, reducing the connection time of the upper space support during offshore transportation and installation on the pile foundation 2 group, and greatly improving the efficiency of large-scale offshore photovoltaic construction. The fixed hinged connection method of the connection structure of the present invention allows a certain degree of freedom of displacement in the horizontal direction between the ball support 1 and the pile foundation 2, which can effectively disperse and relieve the stress generated by wind, absorb and dissipate wind energy, and improve the adaptability and wind load resistance of the structure. The above description is only a few embodiments of the present invention and does not limit the present invention in any way. Although the present invention is disclosed as a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art who, without departing from the scope of the technical solution of the present invention, makes slight changes or modifications based on the technical content disclosed above is equivalent to an equivalent embodiment and falls within the scope of the technical solution.
