Description

Technical Field

[0001] The utility model relates to the technical field of offshore piling vessels, in particular to a piling vessel suitable for pile body construction at a far distance from a photovoltaic electric field. Background Art

[0002] A pile-driving ship is a special ship used for pile driving operations on water. The hull is a steel box structure, and a pile-driving frame is installed at the end of the deck. It can be tilted forward and backward to meet the needs of driving inclined piles. The pile-driving ship is a non-self-propelled ship and is towed into place by a pusher (tug) wheel. Conventional pile-driving ships are mainly used for steel pile construction of large buildings such as offshore bridges and wind power.

[0003] With the development of the photovoltaic power generation industry, the installation of photovoltaic panels has gradually developed from land to sea. The piles used in the photovoltaic industry are smaller in diameter and shorter in length. Some of them are made of concrete, which is quite different from conventional offshore piling, and the equipment cannot be used universally.

[0004] Photovoltaic power generation projects require piling construction at sea first. Compared with land and shallow lake projects, offshore photovoltaic piling projects face the problems of difficulty in moving ships and low ship positioning accuracy due to the influence of water flow and wind and waves. In addition, the design of some offshore wind farms adopts a modular photovoltaic panel frame structure, and the pile spacing reaches tens of meters. Each pile must not only serve the same frame, but also maintain the relative positioning accuracy between each pile, resulting in low pile construction efficiency.

[0005] Therefore, how to improve the efficiency of pile construction by offshore pile-driving vessels for photovoltaic power plants with long pile distances has become a technical problem that needs to be urgently solved by those skilled in the art. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] In addition, in the description of the present invention, unless otherwise specified, “plurality” means two or more.

[0045] Examples, such as Figure 1-Figure 5 As shown, a piling vessel suitable for pile construction at a far distance photovoltaic power field is used for offshore piling construction of support piles and cable piles at a far distance photovoltaic power field; the piling vessel comprises:

[0046] The hull 10 has vertical guide holes (not shown in the figure) at both longitudinal ends of the hull 10 , and the vertical guide holes are located in the middle of the hull 10 in the transverse direction.

[0047] The positioning pile 20 has a one-to-one correspondence with the vertical guide hole, and the positioning pile 20 is arranged in the vertical guide hole in a liftable manner.

[0048] The side pile grippers 30 are arranged on both lateral sides of the hull 10 and can be horizontally extended and swung.

[0049] The stern pile gripper 40 is arranged at the stern of the hull 10, and the stern pile gripper 40 can be horizontally extended and swung.

[0050] The main crane 50 is installed in the middle of the hull 10, and the lifting range of the main crane 50 can cover all the side pile grippers 30 and the stern pile grippers 40. The lifting height corresponding to the main crane 50 meets the pile feeding requirements to any side pile gripper 30 and the stern pile gripper 40.

[0051] The present application is provided with lifting and lowering positioning piles 20 installed at both longitudinal ends of the hull 10. The hull 10 can be quickly fixed on the seabed by lowering the positioning piles 20, and the hull 10 can be quickly released by rising the positioning piles 20, thereby improving the positioning efficiency of the hull 10; the present application is provided with a plurality of side pile grippers 30 installed on both lateral sides of the hull 10, and the side pile grippers 30 can swing horizontally and extend horizontally. The side pile grippers 30 can be used to synchronously position a plurality of supporting piles at the same position of the hull, and then pile driving operations are performed on the plurality of supporting piles, which can not only improve the positioning accuracy of the pile body, but also improve the efficiency of the pile driving operation; the present application is provided with a stern pile gripper 40 installed at the stern of the hull 10, and the stern pile gripper 40 can swing horizontally and extend horizontally. The stern pile gripper 40 can be used to realize the positioning construction of the cable pile, reduce the movement of the hull 10, and thereby improve the efficiency of the pile driving operation.

[0052] It should be noted that the longitudinal direction in this application refers to Figure 2 The double arrow direction in the horizontal direction refers to Figure 2 The lifting and lowering of the positioning pile 20 in the vertical guide hole belongs to the prior art and will not be described one by one here.

[0053] In a specific embodiment, if Figure 1 , Figure 2 As shown, a pair of cranes 60 are installed at the bow of the hull 10.

[0054] This arrangement is because: the main crane 50 is installed in the middle of the longitudinal direction of the hull 10. After the auxiliary crane 60 is installed at the head of the hull 10, the auxiliary crane 60 can cooperate with the main crane 50 to lift the pile body in a horizontal state on the transport ship or the dock to the pile driving ship, and change the pile body from a horizontal state to a vertical state.

[0055] Preferably, Figure 1 , Figure 2 As shown, a living building 70 is installed at the bow of the hull 10, and the auxiliary crane 60 is installed on a lateral side of the living building 70. The living building 70 is used for personnel accommodation and operation.

[0056] In a specific embodiment, if Figure 2 As shown, two side pile grippers 30 are arranged on one lateral side of the hull 10, and the two side pile grippers 30 are arranged at a longitudinal interval, and each side pile gripper 30 can be horizontally extended and swung to achieve horizontal precise positioning of the supporting piles.

[0057] This is because: for the photovoltaic panel frame structure with a long distance between piles, the pile body includes two types of support piles and cable piles. Among them, the number of support piles is four, and the distance between piles is large, so the offshore piling ship can directly enter the field, and use the side pile grippers 30 on both sides of the hull 10 to complete the piling construction of the support piles at one time, and ensure the position accuracy between each support pile.

[0058] Preferably, Figure 2 As shown, two stern pile grippers 40 are provided at the stern of the hull 10, and the two stern pile grippers 40 are arranged with a lateral spacing, and each stern pile gripper 40 can be horizontally extended and swung horizontally to achieve horizontal and precise positioning of the cable pile.

[0059] This arrangement is because: for cable piles far from the photovoltaic field, the cable piles are linearly distributed, and the stern pile gripper 40 at one end of the hull 10 can be used to complete the construction of two cable piles at one time, and then continuous construction can be carried out by moving the ship.

[0060] It should be noted that the side pile gripper 30 and the stern pile gripper 40 in the present application are both prior arts and will not be described in detail here.

[0061] In a specific embodiment, if Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a pile fixing frame 80 is installed in the transverse middle of the hull 10. The pile fixing frame 80 is a steel frame structure, and a plurality of pile grooves 81 for fixing the pile body are provided on both sides of the cross beam at the top of the steel frame structure, so that the pile body can be fixed on the hull 10 in a vertical state.

[0062] This arrangement is because: when the piling ship shuttles in the photovoltaic field, the movement and positioning are limited by the pile foundation, which is very inconvenient, and the pile transport ship is difficult to approach. In this embodiment, a pile fixing frame 80 is installed on the hull 10, and the pile body temporarily transported is fixed by the pile fixing frame 80, so that the piling ship can carry multiple pile bodies in a single entry, thereby improving the efficiency of piling construction.

[0063] Preferably, Figure 1 , Figure 3 As shown, a shelf plate 82 matched with the main crane 50 is provided on the top of the pile fixing frame 80 , and the shelf plate 82 serves as a shelf of the main crane 50 to provide vertical support for the main crane 50 .

[0064] In a specific embodiment, if Figure 1 , Figure 2 As shown, the hull 10 is a barge.

[0065] Preferably, Figure 1As shown, thrusters 11 are provided at both longitudinal ends of the hull 10 to enable the hull 10 to move freely within the photovoltaic field.

[0066] More preferably, Figure 1 , Figure 2 As shown, positioning winches 12 are provided at both ends of the hull 10 in the longitudinal direction, so that the hull 10 can be anchored for a long time under convenient conditions.

[0067] The working process of the pile-driving ship of the utility model is as follows:

[0068] like Figure 2 , Figure 5 As shown, when the side pile gripper 30 and the stern pile gripper 40 are both in the extended state, Figure 5 Area A in the figure is the hoisting range of auxiliary crane 60. Figure 5 Area B in the figure is the lifting range of the main crane 50, and the lifting range of the main crane 50 can cover the pile positions of all four side pile grippers 30 and two stern pile grippers 40, and can also cover all pile positions on the pile fixing frame 80, as well as the position of the pile hammer.

[0069] When the auxiliary crane 60 and the main crane 50 are extended outboard at the same time, the pile body on the pile transport ship or the dock can be lifted from a horizontal state and turned over to a vertical state, and then lifted by the main crane 50 to the pile groove 81 of the pile fixing frame 80.

[0070] When it is necessary to carry out the piling operation of the supporting piles in the photovoltaic field, the hull 10 is driven to the predetermined position by the propeller 11, and then the ship position is fixed by the positioning pile 20, and the four side pile grippers 30 are extended to both sides and adjusted to the designated pile positions, and the main crane 50 hoists the supporting piles into the dragon mouths of the side pile grippers 30, and then the pile driving is carried out by the pile hammer; then the side pile grippers 30 are retracted into the ship, the positioning piles 20 are pulled out, and the hull 10 is moved out of the range of the position by the propeller 11 to carry out the construction of the next position.

[0071] When constructing the cable pile, the stern pile gripper 40 is used for operation, and the process is similar and will not be described in detail.

[0072] Compared with the prior art, this application has at least the following beneficial technical effects:

[0073] (1) The present application realizes a working surface in three directions of the hull by setting up a side pile gripper and a stern pile gripper, which can be used more flexibly for the construction of various pile positions, especially for long-distance photovoltaic piles. One ship position can complete the construction of four supporting piles at one time and ensure the relative accuracy between each pile.

[0074] (2) The present application arranges a main crane and an auxiliary motor on the hull, and the lifting range of the main crane can cover all pile positions, which is not only convenient for lifting the pile body into the dragon mouth of each pile gripper, but also can cover the pile transport ship on the other side of the hull, and can turn the pile body over through the double-machine joint lifting operation, further improving the working efficiency.

[0075] (3) The present application not only realizes the ability to transport piles vertically on the deck by setting up a pile fixing frame, but also can carry as many piles as possible within the limited deck area, and can also serve as a shelf for the main crane.

[0076] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
