Description

Technical Field

[0001] The utility model belongs to the technical field of pile foundation storage and module vehicle ro-ro transportation in offshore wind power projects, and particularly relates to a novel combined pile foundation transportation bottom support. Background Technique

[0002] The pile foundation of the offshore wind power project has a diameter of 7 - 10m, a length of 70 - 100m, and a weight of 1000 - 1800 tons. The pile foundation storage and ro-ro transportation bottom support needs to meet the requirements of the pile foundation's external dimensions and weight. The pile foundation storage and ro-ro transportation bottom support needs to adopt a suitable structural form according to environmental conditions to ensure the smooth boarding and disembarking of the module vehicle.

[0003] Currently, the pile foundation is transported onto the ship by ro-ro using a module vehicle. After the pile foundation is produced, it is usually stored on a platform. To transport it to the transport ship, a track usually needs to be laid, and then it is transported by the module vehicle. To achieve the limit fixation after transportation and loading onto the ship, a transportation bottom support is usually required for cooperation. Currently, most of the pile foundation transportation bottom supports adopt an integral structure. When the height of the bottom support is relatively low, the module vehicle cannot be separated from the bottom support after transportation. When the height of the bottom support is relatively high, when the module vehicle boards the ship, it is impossible to determine whether the lower end of the bottom support will get stuck at the edge position of the transport ship deck; at the same time, if the pile foundation storage platform is relatively high and the height of the bottom support needs to be increased, there will be a situation where the lifting stroke of the module vehicle is limited and it cannot be ro-ro loaded onto the vehicle; and currently, the transportation bottom support cannot meet the transportation requirements for pile foundations with different diameters. Summary of the Invention

[0004] The utility model provides a novel combined pile foundation transportation bottom support to solve the problems that the height of the existing pile foundation transportation bottom support cannot adapt to various transportation situations and cannot be used for pile foundations with multiple diameters. By cooperating the split - type height - increasing platform with the transportation bottom support, it ensures the separation of the module vehicle from the bottom support. The arc support arranged in a sliding manner is suitable for the transportation of pile foundations with multiple diameters, and effectively reduces the transportation difficulty of the pile foundation.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows:

[0006] A novel combined pile foundation transportation bottom support is used to transport the pile foundation to the deck of a transport ship in cooperation with a modular vehicle. It includes a transportation bottom support main body, a heightening platform, an arc support, and a connecting piece. The transportation bottom support main body includes a support frame and a support platform. At both ends of the lower side of the support frame, support platforms are fixedly arranged. Below each support platform, a heightening platform is correspondingly arranged. The heightening platform is fixedly arranged on the deck, and the heightening platform is fixedly connected to the corresponding support platform. Two slide rails are symmetrically arranged above the support frame. In each slide rail, an arc support is slidably arranged. The cross-section of the arc support is triangular, and the opposite sides of the two arc supports are arc surfaces. A pile foundation is arranged between the arc surfaces of the two arc supports. The arc support is fixedly connected to the support frame through a connecting piece, realizing a split heightening platform and a transportation bottom support main body. The adaptable adjustment during the transportation of pile foundations with different diameters is achieved through the slidably arranged arc support.

[0007] Preferably, each arc support includes a bottom plate, an arc plate, and a support rod. The bottom plate is slidably arranged in the corresponding slide rail. A plurality of support rods are fixedly arranged on the bottom plate, and an arc plate is fixedly arranged above the support rods. The arc plate and the bottom plate are connected through a plurality of support rods.

[0008] Preferably, a plurality of installation holes are formed in the slide rails of the support frame, and a plurality of through holes corresponding to the installation holes are formed in the bottom plate. The connecting piece adopts a high-strength bolt connection pair. The arc support is fixed by cooperating with the corresponding through holes and installation holes, and the arc support is fixed through the high-strength bolt connection pair.

[0009] Preferably, each heightening platform is fixedly connected to the deck through a plurality of L-shaped plates. The L-shaped plates are fixedly welded to the deck, and the heightening platform is fixed through the L-shaped plates.

[0010] Preferably, the support platform and the heightening platform are tightly connected by bolts, which facilitates disassembly and assembly while ensuring the fixed connection effect.

[0011] Through the above technical solutions, the beneficial effects of the present utility model are as follows:

[0012] 1. By adopting a split design for the transportation bottom support main body and the heightening platform, the present utility model solves the problem of interference between the transportation bottom support and the deck and the dock shore due to the limited jacking stroke of the modular vehicle when the pile foundation is rolled onto the ship, avoiding the situation where the lower end of the transportation bottom support main body gets stuck at positions such as the deck and the dock shore, and effectively avoiding the problem that the transportation bottom support main body cannot reach the bottom of the pile foundation.

[0013] 2. By slidably arranging the arc support on the transportation bottom support main body and fixing it with a high-strength bolt connection pair after adjusting the position of the arc support, the position of the arc support on the transportation bottom support main body can be adjusted according to the diameter of the pile foundation, making the transportation bottom support highly versatile.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The present utility model will be further described below in conjunction with the drawings and the detailed description of the embodiments:

[0019] As Figures 1 to 3 shown, this embodiment provides a new type of combined pile foundation transportation bottom support. By cooperating with the modular vehicle 1, the pile foundation 2 is transported to the deck 3 of the transport ship. The pile foundation 2 is usually placed on a storage platform. The modular vehicle 1 is used to move a new type of combined pile foundation transportation bottom support of the present application to one side of the storage platform, and then the pile foundation 2 is rolled onto the vehicle.

[0020] It includes a transportation bottom support main body, a heightening platform 4, an arc support, and a connecting piece 5. The transportation bottom support main body includes a support frame 6 and a support platform 7. The two ends of the lower side of the support frame 6 are fixedly provided with support platforms 7. The bottom support is loaded onto the vehicle by the distance between the support platforms 7. The pile foundation 2 is supported and transported by the support frame 6. A heightening platform 4 is correspondingly arranged below each support platform 7. The heightening platform 4 is fixedly arranged on the deck 3. After the modular vehicle 1 transports the pile foundation 2 to the deck 3, the support platform 7 of the transportation bottom support main body and the heightening platform 4 are placed corresponding to each other up and down. The heightening platform 4 is fixedly connected to the corresponding support platform 7. The support platform 7 and the heightening platform 4 are fixedly connected by bolts. After the support platform 7 is placed above the heightening platform 4, it is fixed.

[0021] Two slide rails are symmetrically arranged above the support frame 6. Arc supports are slidably arranged in the slide rails. The cross-section of the arc support is triangular, and the opposite side surfaces of the two arc supports are arc surfaces. The pile foundation 2 is arranged between the arc surfaces of the two arc supports. During transportation, the pile foundation 2 is limited and fixed by the two arc supports. The arc support and the support frame 6 are fixedly connected by a connecting piece 5. The connecting piece 5 adopts a high-strength bolt connection pair to ensure the fixing effect on the arc support, and further ensure the limiting effect on the pile foundation 2.

[0022] Each of the arc supports includes a bottom plate 8, an arc plate 9, and a support rod 10. The bottom plate 8 is slidably disposed within a corresponding slide rail. A plurality of support rods 10 are fixedly provided on the bottom plate 8, and an arc plate 9 is fixedly provided above the support rods 10. The movement of the arc support is achieved by the movement of the bottom plate 8 within the slide rail to adapt to the transportation of pile foundations 2 with different diameters. The limiting of the pile foundation 2 is achieved through the cooperation of two arc plates 9, and the bottom plate 8 and the arc plate 9 are connected by the support rods 10 to support the arc plate 9.

[0023] A plurality of mounting holes are formed in the slide rail of the support frame 6, and a plurality of through holes corresponding to the mounting holes are formed in the bottom plate 8. The connecting member 5 realizes the fixation of the arc support by cooperating with the corresponding through holes and mounting holes.

[0024] As Figure 3 shown, each of the raised platforms 4 and the deck 3 are fixedly connected by a plurality of L-shaped plates 11, and the L-shaped plates 11 are fixedly welded to the deck 3. Through the arrangement of the L-shaped plates 11, the problem that directly welding the raised platform 4 to the deck 3 has too large a welding area, which is not convenient for subsequent disassembly and easily damages the deck 3, is effectively reduced.

[0025] As Figure 2 shown, it is a structural schematic diagram of a modular vehicle, including a nose (i.e., a power module) on the left and a vehicle body on the right. A jacking mechanism is provided between the vehicle body and the wheels below to drive the vehicle body to lift and lower.

[0026] During use, according to the structure of the deck 3 of the transport ship's hull type, the raised platforms 4 are first arranged at corresponding positions on the deck 3 and fixed by a plurality of L-shaped plates 11, and the L-shaped plates 11 are fixedly welded to the deck 3;

[0027] According to the distance between each group of raised platforms 4 and the center of gravity position of the pile foundation 2, the transport bottom support main body is arranged on the modular vehicle 1. The modular vehicle 1 carries the transport bottom support main body and moves to below the pile foundation 2 on one side of the storage platform. Install the arc support on the side away from the pile foundation 2 and fix it through the connecting member 5 (high-strength bolt connection pair). Subsequently, roll the pile foundation 2 onto the vehicle. After rolling the pile foundation 2 onto the support frame 6 of the transport bottom support main body, install the other arc support and fix it through the connecting member 5 (high-strength bolt connection pair).

[0028] The modular vehicle 1 carries the pile foundation 2 and gets on the ship along a fixed route. When it arrives on the deck 3 and moves to a position where the support platforms 7 of the transport bottom support main body are respectively directly above the corresponding raised platforms 4, the modular vehicle 1 stops. Place the transport bottom support main body on the raised platforms 4 and fix it with bolts. Subsequently, the modular vehicle 1 drives away, and repeat the above steps.

[0029] At the same time, the storage of the pile foundation 2 also adopts the above steps.

[0030] The above-described embodiments are only the preferred embodiments of the present utility model, and do not limit the scope of implementation of the present utility model. Therefore, any equivalent changes or modifications made according to the structure, features, and principles described in the scope of the present utility model patent shall be included within the scope of the patent application of the present utility model.
