Description

Technical Field

[0001] This utility model relates to a tooling structure that integrates steel pipe pile transportation and turning. Background Technology

[0002] As offshore wind power gradually expands into deeper waters, the application of jacket foundations is becoming increasingly widespread. Jacket foundations consist of steel pipe piles and the jacket structure itself. The transportation and turning of the steel pipe piles are prerequisites for pile driving. Conventional steel pipe pile transportation uses a single-layer method. After arrival at the site, the piles are turned using a double-ship lifting or double-crane lifting method, transforming them from a horizontal position during transport to a vertical position for pile driving. Single-layer transportation has low utilization efficiency for the transport vessels, while double-crane lifting is slow and requires more ship and machinery equipment.

[0003] Therefore, a tooling structure integrating steel pipe pile transportation and turning is proposed to address the above problems. Utility Model Content

[0013] 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.

[0014] like Figure 1-7 As shown, a tooling structure integrating steel pipe pile transportation and turning includes a lower transportation tooling 1, an upper transportation tooling 2, a lower turning tooling 4, and an upper turning tooling 5. The lower transportation tooling 1 is set on the deck, and the upper part is used to place the first layer of steel pipe piles. The upper transportation tooling 2 is used to place the second layer of steel pipe piles between the gaps of the first layer of steel pipe piles. The lower turning tooling 4 and the upper turning tooling 5 are set on one side of the lower transportation tooling 1 and are arranged alternately for turning the first layer of steel pipe piles and the second layer of steel pipe piles, respectively.

[0015] Specifically, the lower transport fixture 1 includes a crossbeam 11, with multiple sets of V-shaped bottom supports 12 connected at equal intervals on the lower end face of the crossbeam 11, and a bottom support column 13 connected between each V-shaped bottom support 12; multiple first side supports 14 are connected at equal intervals on both sides of the crossbeam 11; and multiple columns 15 are connected at equal intervals on the upper end face of the crossbeam 11, with second side supports 16 connected to both sides of each column 15.

[0016] Specifically, the crossbeam 11 directly bears the weight of the steel pipe pile, and rubber sheets or wooden blocks are placed at the part in contact with the steel pipe pile to prevent damage to the paint of the steel pipe pile; the second side support 16 is used to prevent the steel pipe pile from rolling during transportation; the figure-eight bottom support 12 and the bottom support column 13 are directly welded to the ship deck to transfer the weight of the steel pipe pile, and at the same time raise the transportation height of the steel pipe pile, so that the pile top turner can smoothly clamp the pile wall during the turning operation; the first side support 14 is used to resist the lateral load and the longitudinal bite load.

[0017] Specifically, the upper transport fixture 2 is composed of two double-I-beams combined into a V-shape, with a first reinforcing rib 21 installed between the flanges of the double-I-beams. The upper transport fixture 2 is V-shaped with an included angle of 110°, and each side is composed of double-I-beams to enhance compressive strength. The first reinforcing rib 21 is installed near the flange where it contacts the steel pipe pile to prevent the flange from being damaged. Rubber sheets or wooden blocks are placed at the contact points with the steel pipe pile to prevent damage to the paint on the steel pipe pile.

[0018] Specifically, the lower-level turning fixture 4 includes a first upright 41, which is located at the pipe opening of the first-level steel pipe pile. The side of the first upright 41 facing away from the lower-level transport fixture 1 is connected to a third side support 42. The lower ends of the first upright 41 and the third side support 42 are both connected to the deck. A second reinforcing rib 43 is provided between the flanges of the I-beams of the first upright 41.

[0019] Specifically, the upper turning fixture 5 includes a second upright 51, which is located at the pipe opening of the second layer steel pipe pile. The side of the second upright 51 facing away from the lower transport fixture 1 is connected to the fourth side support 52. The lower ends of the second upright 51 and the fourth side support 52 are both connected to the deck. A third reinforcing rib 53 is provided between the flanges of the I-beam of the second upright 51.

[0020] Specifically, the upper turning fixture 5 has the same structure as the lower turning fixture 4, but is taller than the lower turning fixture 4, in order to meet the turning requirements of the upper steel pipe piles.

[0021] Specifically, the transportation process employs a lower layer of five steel pipe piles (3) and an upper layer of three steel pipe piles (3). Four lower-level transport fixtures (1) are arranged below the five lower-level steel pipe piles (3); four upper-level transport fixtures (2) are arranged below the three upper-level steel pipe piles (3); a lower-level turning fixture (4) is arranged 20cm from the pile tip of the lower-level steel pipe piles; and an upper-level turning fixture (5) is arranged 20cm from the pile tip of the upper-level steel pipe piles. The arrangement of all steel pipe piles ensures that the tops of adjacent steel pipe piles are staggered by approximately 2 meters, so that the pile-turning device at the pile top can smoothly clamp the pile wall during the turning operation.

[0022] Specifically, during the turning operation, the pile top turning device clamps the pile top and lifts the pile top. The steel pipe pile 3 then slides backward at an incline. After the turning fixture 4 stops, the steel pipe pile stops sliding backward and turns into a vertical state with the turning fixture 4 as the center.

[0023] This integrated tooling structure for transporting and turning steel pipe piles comprises a lower transport tool 1 mounted on the deck, used to place the first layer of steel pipe piles. The upper transport tool 2 is used to place the second layer of steel pipe piles between the first layer. The lower turning tool 4 and the upper turning tool 5 are positioned alternately on one side of the lower transport tool 1, used for turning the first and second layers of steel pipe piles respectively. This achieves multi-layer transport and direct turning of steel pipe piles, improving the transport efficiency of the transport vessel, reducing the need for specialized turning equipment, and increasing construction efficiency.

[0024] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are 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.
