Currently, most monopile foundations are installed offshore using pile grippers to adjust the verticality of the steel piles. Existing pile grippers for monopile foundations are all hydraulically driven. However, hydraulic systems have higher configuration requirements, occupy more ship space, and have relatively higher investment costs. Furthermore, hydraulic drives have slow response times and require extensive maintenance, making them unsuitable for the rapid adjustment needs of offshore wind power monopile foundation construction.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model is described below with reference to specific examples shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the present utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0017] like Figure 1-3 The present invention relates to an electrically driven pile gripper device for the construction of monopile foundations in offshore wind power. The device includes a guide rail module, an adjustment and compensation module, and an electric jacking module. The adjustment and compensation module is mounted on the guide rail module and is connected to the electric jacking module, which in turn is connected to the monopile foundation 7. The guide rail module includes a vertical guide rail 1 and a horizontal guide rail 3. Both ends of the horizontal guide rail 3 are connected to the vertical guide rail 1. The adjustment and compensation module includes a longitudinal drive cylinder 4 and a horizontal drive cylinder 5. Both ends of the horizontal guide rail 3 are respectively mounted with... The longitudinal drive electric cylinder 4 is connected to the adjacent transverse drive electric cylinder 5 via a push rod. The electric jacking module includes a pile gripper module 6 and a jacking drive electric cylinder 9. The pile gripper module 6 includes a fixed gripper arm 11 and a movable gripper arm 10. The outer side of the fixed gripper arm 11 is connected to the transverse drive electric cylinder 5 via a push rod. The fixed gripper arm 11 and the movable gripper arm 10 are connected and wrapped around the side of the monopile foundation 7. The jacking drive electric cylinders 9 are respectively installed on the pile gripper module 6.

[0018] By using an electric cylinder instead of a traditional hydraulic cylinder, rapid adjustment and compensation are achieved, making it suitable for rapid compensation and adjustment during the construction of monopile foundations 7 in marine environments, thereby improving the verticality of the monopile foundations 7.

[0019] The vertical guide rail 1 is rigidly connected to the side of the floating vessel. An electrically driven vertical slider 2 is installed on the vertical guide rail 1. The electrically driven vertical slider 2 slides on the vertical guide rail 1. The sides of the electrically driven vertical slider 2 are fixedly connected to both ends of the transverse guide rail 3. The transverse guide rail 3 is set perpendicular to the vertical guide rail 1.

[0020] The longitudinal drive electric cylinder 4 is fixedly installed on the transverse guide rail 3. A transverse slider is provided on the transverse guide rail 3 between the longitudinal drive electric cylinders 4. A transverse drive electric cylinder 5 is provided on the transverse slider. The transverse slider slides on the transverse guide rail 3. The push rod direction of the transverse drive electric cylinder 5 is perpendicular to the push rod direction of the longitudinal drive electric cylinder 4.

[0021] The pile clamp module 6 is generally octagonal. The outer side of the fixed clamp arm 11 is hinged to the push rod of the transverse drive electric cylinder 5. One end of the fixed clamp arm 11 is hinged to one end of the movable clamp arm 10, and the other end of the fixed clamp arm 11 is connected to the other end of the movable clamp arm 10 through a pin. A clamp arm electric cylinder 8 is provided at one end of the fixed clamp arm 11. The clamp arm electric cylinder 8 is connected and fixed to the fixed clamp arm 11 through a fixing plate. The push rod on the clamp arm electric cylinder 8 is connected to the movable clamp arm 10. The clamp arm electric cylinder 8 drives the movable clamp arm 10 to open or close through the telescopic push rod.

[0022] The fixed arm 11 is equipped with a push-drive electric cylinder 9, and the movable arm 10 is equipped with three push-drive electric cylinders 9.

[0023] After the vertical guide rail 1 is fixedly connected to the side of the floating vessel, the arm-clamping cylinder 8 uses a telescopic push rod to close the fixed arm 11 and the movable arm 10 and fix them together with a pin. The arm-clamping cylinder 8 clamps the monopile foundation 7 and performs the construction of the monopile foundation 7. At the same time, the control elements of the two longitudinal drive cylinders 4, the two lateral drive cylinders 5, and the two electric vertical sliders 2 output compensation signals, causing the two longitudinal drive cylinders 4, the two lateral drive cylinders 5, and the two vertical electric sliders 2 to perform motion compensation actions. For the longitudinal drive cylinders 4 and the two lateral drive cylinders 5... The control of 5 and the two electric vertical sliders 2 can be automatically controlled by a PLC control system installed on the floating vessel. A single pile verticality detection sensor can be installed on the guide rail module to detect verticality and facilitate automatic compensation adjustment. The electric drive compensation mechanism, consisting of two longitudinal drive cylinders 4 and two transverse drive cylinders 5, is used to adjust and control the relative position of the pile gripper body 6 and the ship. This keeps the pile gripper body 6 relatively stationary during the pile driving process, achieving the purpose of compensating for the ship's motion and ensuring that the verticality of the single pile foundation 7 is not affected by the ship's motion.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of the utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
