[0036] Furthermore, in the description of the present invention, unless otherwise specified, “plurality” means two or more.

[0037] According to the first aspect of the present application, see Figures 1 to 5 First, an adjustable pile gripper is provided, including a pile gripping mechanism 400, a triangular connection structure and a horizontal adjustment mechanism.

[0038] The pile-holding mechanism 400 includes a vertically arranged connecting arm 301 , on which a plurality of holding hoops are provided, and the holding hoops are used to hold the pipe pile 500 .

[0039] The horizontal adjustment mechanism comprises a telescopic arm 100, one end of which is used to connect to the ship, and the other end of which is connected to the triangular connection structure. The horizontal adjustment mechanism is used to adjust the position of the pipe pile 500 on the horizontal plane.

[0040] The triangular connection structure is used to connect the connection arm 301 and the telescopic arm. The inclination angle of the connection arm in the vertical direction is adjusted through the triangular connection structure to adjust the verticality of the pipe pile.

[0041] In one practicable manner, if Figure 3 and Figure 4 As shown, the telescopic arm 100 includes an extension arm 120 and a fixed arm 110 connected by pulling, the fixed arm 110 is hollow inside, the extension arm 120 is coaxially inserted in the fixed arm 110, and the extension arm 120 includes an insertion end and an extension end.

When the telescopic cylinder 130 is extended, the extension arm 120 extends toward the side of the pipe pile 500, and when the telescopic cylinder 130 is retracted, the extension arm 120 is retracted to the side away from the pipe pile 500, so as to complete the precise adjustment of the position of the pipe pile 500 in the primary position adjustment direction.

[0042] Specifically, Figure 1 and Figure 3 As shown, a second ear plate 122 is provided on the extension arm 120 , and the extension arm 120 is hinged to the telescopic cylinder 130 through the second ear plate 122 .

[0043] In an operative manner, the triangular connection structure further comprises a first articulated seat 302 and a second articulated seat provided on the extended end of the telescopic arm 100. The connecting arm 301 is articulated with the first articulated seat 302, a third oil cylinder 303 is provided on the second articulated seat, the bottom of the third oil cylinder 303 is articulated with the second articulated seat, a third articulated seat is provided in the middle of the connecting arm 301, and the top of the third oil cylinder 303 is articulated with the third articulated seat.

The extended arm 120, the third oil cylinder 303 and the amplitude change mechanism are articulated to form a triangular articulated structure, and the angle between the axis of the connecting arm 301 and the axis of the extended arm 120 is controlled by changing the extended length of the third oil cylinder 303, so as to adjust the verticality of the connecting arm 301, thereby accurately adjusting the verticality of the pipe pile 500. When the hull tilts, the verticality of the pipe pile 500 can be adjusted through the triangular connection structure, avoiding frequent adjustment of the ballast water of the hull, thereby improving the operating efficiency.

[0044] In an operative manner, the horizontal adjustment mechanism further comprises a first fixed support 204 and a second fixed support 201 respectively fixed to the ship, and the first fixed support 204 and the second fixed support 201 are arranged along the arrangement direction of the telescopic arm 100.

The arrangement direction of the second fixed support 201 is the secondary position adjustment direction, and the secondary position adjustment direction is perpendicular to the primary position adjustment direction. The position of the fixed arm 110 in the secondary position adjustment direction is precisely controlled and adjusted by the first oil cylinder 202. Therefore, by setting the horizontal adjustment mechanism, the position of the pipe pile 500 on the horizontal plane can be adjusted without the need to transport the moving hull, thereby improving the installation accuracy and efficiency of the pipe pile 500.

[0047] It should be noted that if Figure 2 As shown, a cylinder support 203 is provided at one end of the first cylinder 202 away from the telescopic arm 100 , and the height of the first cylinder 202 is raised to the same height as the telescopic arm 100 through the cylinder support 203 , so as to facilitate transmission connection between the first cylinder 202 and the telescopic arm 100 .

The upper guide surface and the lower guide surface are provided to prevent the telescopic arm 100 from sliding off and detaching from the second fixed support 201 during the secondary position adjustment process, and to prevent the telescopic arm 100 from tipping over, so as to limit the telescopic arm 100 in the vertical direction.

[0050] In an practicable manner, the pile-holding mechanism 400 further includes a plurality of hoops, which are evenly distributed on the connecting arm 301 , and are used to clamp the pipe pile 500 , so that when the verticality of the connecting arm 301 changes, the verticality of the pipe pile 500 is adjusted accordingly.

[0051] In one practicable manner, if Figure 5 As shown, a first connecting ear plate 304 is provided on the side of the connecting arm 301 close to the pipe pile 500 , and each of the clamps includes two arc clamps 401 , and the ends of the arc clamps 401 are connected to the first connecting ear plate 304 via a second pin 305 .

[0052] like Figure 5 As shown, a second connecting ear plate 306 is provided on the side surface of the connecting arm 301 which is perpendicular to the surface where the first connecting ear plate 304 is located, and each of the circular arc embracing arms 401 is respectively connected to a second oil cylinder 402 for controlling the opening and closing of the circular arc embracing wall, and the cylinder body of the second oil cylinder 402 for controlling the opening and closing of the circular arc embracing wall is hinged to the variable-length embracing arm through the second connecting ear plate 306, and the opening and closing angle of the circular arc embracing arm 401 is controlled by the second oil cylinder 402 for controlling the opening and closing of the circular arc embracing wall, so as to clamp pipe piles 500 of different pipe diameters.

[0053] It should be noted that Figure 5 The dotted line portion in the figure represents a schematic diagram of the two arc arms 401 in an open state.

[0054] In one practicable manner, if Figure 5 As shown, a plurality of push racks 403 are arranged inside each of the arc arms 401. In this embodiment, two push racks 403 are arranged inside each arc arms 401. Therefore, the four push racks 403 in the clamp are evenly arranged inside the clamp, so that the force is evenly applied when the pipe pile 500 is clamped.

[0055] In an practicable manner, a roller is provided at the end of each of the pushing frames 403 , and the roller is used to abut against the surface of the pipe pile 500 to prevent damage to the surface of the pipe pile 500 during the clamping process.

[0056] According to a second aspect of the present application, there is further provided a pile-driving vessel, comprising a hull and a pile gripper arranged on the hull, wherein the pile gripper is the adjustable pile gripper provided in the first aspect.

[0057] In summary, the adjustable pile gripper and pile-driving ship provided by the present application can solve the defects of the offshore pile driving guide equipment being unable to shift and the low construction efficiency. Through the setting of the horizontal adjustment mechanism, after the ship position is roughly determined, the position of the pipe pile 500 at each pile position is adjusted on the horizontal plane to ensure the pile driving accuracy. Through the setting of the triangular connection structure, the angle between the axis of the connecting arm and the axis of the telescopic arm 100 is adjusted to compensate for the hull heel, adapt to different hull inclination angles, and ensure the verticality of the installation of the pipe pile 500. Frequent adjustment of the hull ballast water is avoided, and the operation efficiency is improved. Through the setting of the arc-shaped second fixed support 201, the adjustment trajectory of the pipe pile 500 in the secondary position adjustment direction is a fan, which increases the adjustment coverage area and meets different adjustment requirements. Therefore, according to the adjustable pile gripper and pile-driving ship provided by the present application, the installation accuracy and installation efficiency of the pipe pile 500 can be greatly improved, which is conducive to promotion and use.
