Description

Technical Field

[0001] This utility model relates to the field of steel pipe pile driving technology, specifically to a steel pipe pile driver for offshore wind power. Background Technology

[0002] Piling refers to the process of driving a pile to a depth below the natural ground surface by using a steel pile driver attached to the pile top and then pressing the pile into the ground to the designed depth using a pile driver. It achieves precise positioning by transmitting hammering force through special tools and is a key construction technology in building engineering to drive precast piles to the designed elevation below the ground or water surface. When driving offshore wind power steel pipe piles, it is usually necessary to use a suitable pile driver to drive the pile to the designed depth below the water surface.

[0003] Existing wind turbine steel pipe pile drivers are generally ordinary pipe structures. They rely on gravity to attach the bottom of the driver to the steel pipe pile and then place it on top of the pile to complete the connection and positioning. After connecting to the pile driver at the top, they accurately transmit the hammering force. However, the seabed geological structure is complex. When driving the steel pipe pile, it may suddenly encounter soft silt, causing the pile to sink quickly. Existing drivers are only placed on top of the pile for connection and cannot provide tension. When the pile sinks rapidly, the driver may fall directly, even damaging the foundation below, causing serious damage and loss. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide a pile driver for offshore wind power steel pipe piles, which can automatically clamp the side wall of the steel pipe pile after falling to the top of the steel pipe pile, so that it can be stably installed on the steel pipe pile.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0006] A pile driver for offshore wind power steel pipe piles includes a pile driver body, with a hanging ring on the side wall, and further includes:

[0007] A connecting collar is set at the bottom of the pile driver body and is adapted to the top of the steel pipe pile. The pile driver body is arranged directly above the steel pipe pile through the connecting collar.

[0008] The lifting and clamping structure is set on the inner wall of the pile driver body. It includes a sliding plate that is slidably set on the inner wall of the pile driver body. A mounting seat is set on the inner wall of the pile driver body below the sliding plate. A clamping rod is hinged on the mounting seat. A clamping plate that is adapted to the inner wall of the steel pipe pile is set at the bottom of the clamping rod. After the sliding plate slides down, the clamping rod flips down and the side wall of the steel pipe pile is clamped between the clamping plate and the side wall of the connecting collar.

[0009] As an improvement, a sliding groove is provided on the side wall of the pile driver body, and a hanging ring three is provided on the top of the outer side wall of the sliding plate. The hanging ring three passes through and slides in the sliding groove. A hinge seat is provided at the bottom of the inner side wall of the sliding plate. A flipping rod is hinged on the hinge seat. A control rod is hinged to the other end of the flipping rod, and the other end of the control rod is connected and fixed to the top of the clamping rod. After the hanging ring three is pulled up, the flipping rod pulls the control rod to flip, so that the clamping rod opens.

[0010] As an improvement, a limiting plate is provided on the inner wall of the pile driver body below the sliding plate, and a return spring is provided between the limiting plate and the bottom of the sliding plate. After the pile driver body is arranged on the top of the pile driver body, the return spring pulls the sliding plate down.

[0011] As an improvement, the top of the connecting collar is fixed to the pile driver body, the bottom is a funnel-shaped structure that gradually increases in size, and multiple hanging rings are evenly arranged on the outer side of the connecting collar along the circumference.

[0012] As an improvement, a protective pad layer is provided on the bottom surface of the pile driver body.

[0013] The advantages of this utility model compared with the prior art are as follows:

[0014] 1. This utility model is equipped with a lifting and clamping structure. When the pile driver body is lifted, the clamping rod will automatically open, making it convenient for the pile driver body to be placed on the steel pipe pile. After the pile driver body is placed on the steel pipe pile, the clamping rod will automatically flip downward to clamp the side wall of the steel pipe pile between the clamping plate and the connecting collar, thereby improving the stability of the connection between the pile driver and the steel pipe pile, preventing the pile driver from detaching from the steel pipe pile, and making it safer and more reliable to use.

[0015] 2. This utility model is equipped with a connecting collar, and the bottom of the connecting collar is a funnel-shaped structure that gradually increases in size. This facilitates the positioning of the pile driver body at the specific location of the top of the steel pipe pile, and also makes it easier for the steel pipe pile to enter the connecting collar, making it more convenient to use.

[0022] In the description of this utility model, it should be understood that the terms "center," "lateral," "upper," "lower," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Additionally, the term "comprising" and any variations thereof are intended to cover non-exclusive inclusion.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] A type of offshore wind power steel pipe pile driver, such as Figure 1 , 2 As shown in Figure 3, the device includes a pile driver body 1, which is a vertically arranged tube structure. The lower half of the tube gradually increases in size, and the ends of the tube are thickened to improve its strength. A protective pad 16 is provided on the bottom surface of the pile driver body 1, and a pair of hanging rings 3 are symmetrically arranged on the outer side wall. A pair of vertical grooves 5 are symmetrically arranged on the side wall, and a pair of lifting clamping structures are provided on the inner side wall corresponding to the grooves 5. A connecting collar 2 is sleeved and fixed at the bottom.

[0025] like Figure 2 , 3As shown in Figure 5, the lifting and clamping structure includes a sliding plate 6 slidably disposed on the inner wall of the pile driver body 1. A hanging ring 7 is provided on the top of the outer wall of the sliding plate 6, and the hanging ring 7 passes through and is slidably disposed in the slide groove 5. A hinge seat 12 is provided at the bottom of the inner wall of the sliding plate 6. A flipping rod 15 is hingedly disposed on the hinge seat 12. An installation seat 13 is provided on the inner wall of the pile driver body 1 below the sliding plate 6, and a clamping rod 10 is provided on the installation seat 13. The top of the clamping rod 10 is hinged to the installation seat 13 and is connected and fixedly connected to a control rod 14. A clamping plate 11 is provided at the bottom. The clamping plate 11 is an arc-shaped plate structure adapted to the inner wall of the steel pipe pile and has a rough surface. The other end of the control rod 14 is hinged to the other end of the flipping rod 15. After the sliding plate 6 slides down, the clamping rod 10 flips down, so that the side wall of the steel pipe pile is clamped between the clamping plate 11 and the side wall of the connecting collar 2.

[0026] like Figure 3 , 5 As shown, a limiting plate 9 is provided on the inner wall of the pile driver body 1 below the sliding plate 6, and a return spring 8 is provided between the limiting plate 9 and the bottom of the sliding plate 6. The return spring 8 has strong strength. When the pile driver body 1 is lifted by the two side hanging rings 7, under the weight of the pile driver body 1, the pile driver body 1 sinks relative to the sliding plate 6, causing the sliding plate 6 to pull the return spring 8 to extend and move upward. The clamping rod 10 flips open and moves away from the side wall of the connecting collar 2. After the pile driver body 1 falls and rests on the top of the steel pipe pile, the return spring 8 extends and retracts to pull back the sliding plate 6, causing the clamping plate 11 to flip down and tightly abut against the inner wall of the steel pipe pile.

[0027] like Figure 2 , 3 As shown in Figure 4, the connecting collar 2 is adapted to the top of the steel pipe pile, and the top is sleeved and fixed on the pile driver body 1. Multiple hanging rings 4 are evenly arranged on the outer side along the circumference. The bottom of the ring is a funnel-shaped structure that gradually increases in size. This structure is used to position and guide the top of the steel pipe pile, so that the steel pipe pile can be smoothly inserted into the connecting collar 2 and overlapped with the bottom of the pile driver body 1, so that the pile driver body 1 is positioned directly above the steel pipe pile.

[0028] In the specific implementation of this embodiment:

[0029] Connect the lifting device hook to the two side hanging rings 7, start the lifting device to lift the pile driver body 1. Under the weight of the pile driver body 1, the pile driver body 1 sinks relative to the sliding plate 6, causing the sliding plate 6 to pull the return spring 8 to extend and move upward. The flipping rod 15 follows the sliding plate 6 to move upward and flips, pulling the control rod 14 to flip, causing the clamping rod 10 to flip open and move away from the side wall of the connecting collar 2. After the pile driver body 1 is transferred to the top of the steel pipe pile by the lifting device, it is slowly lowered by the lifting device. Under the positioning and guidance of the connecting collar 2, the steel pipe pile is inserted into the connecting collar 2. After the pile driver body 1 falls and rests on the top of the steel pipe pile, the return spring 8 extends and retracts to pull back the sliding plate 6, causing the clamping plate 11 to flip down and tightly abut against the inner wall of the steel pipe pile. The side wall of the steel pipe pile is clamped between the clamping plate 11 and the side wall of the connecting collar 2, and the pile driver body 1 is stably installed directly above the steel pipe pile.

[0030] After the pile driver is positioned on top of the pile feeder body 1 using a lifting device, the pile driver is started. The pile feeder body 1 transmits the hammering force to the steel pipe pile, causing the steel pipe pile to sink. When the steel pipe pile suddenly encounters soft silt and sinks, the pile feeder body 1 follows the steel pipe pile into the sinking through the lifting and clamping structure. Under the drag of the lifting device cable, it provides a certain pulling force to the steel pipe pile, slowing down the sinking of the steel pipe pile and preventing itself from falling off and damaging the foundation below.

[0031] After the pile driving is completed, the pile driver is removed by the lifting device, and then the pile feeder body 1 is lifted by the lifting device. The two side hanging rings 7 pull the sliding plate 6 upward, and the clamping rod 10 flips open, away from the side wall of the connecting collar 2, thereby releasing the clamping on the side wall of the steel pipe pile. After being lifted by the lifting device, it is transported back to the lower base.

[0032] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
