Description

Technical Field

[0001] This application relates to the field of lifting clamps, and in particular to a wind turbine monopile lifting clamp. Background Technology

[0002] As a crucial component of offshore wind power foundations, wind turbine monopiles are characterized by their large diameter, heavy weight, and wide variation in wall thickness, placing extremely high demands on the design of lifting clamps. Particularly during lifting, it is essential to align the center of gravity of the lifting clamp with that of the pipe pile to ensure installation stability. However, existing lifting clamps rely on welding counterweights to the clamp for center of gravity adjustment, which is cumbersome when readjustment is needed, leading to operational inconvenience. Utility Model Content

[0003] To improve the ease of adjusting the center of gravity, this application provides a wind turbine monopile hoisting clamp.

[0004] This application provides a wind turbine monopile hoisting clamp, which adopts the following technical solution:

[0005] A wind turbine monopile hoisting clamp includes a main lifting beam and a first counterweight. A first mounting groove is provided above the main lifting beam, and the length of the first mounting groove is parallel to the length of the main lifting beam. The first counterweight is slidably connected to the first mounting groove. The first counterweight is provided with a limiting component to limit the sliding position of the first counterweight. Several second counterweights are detachably connected to the first counterweight.

[0006] By adopting the above technical solution, a first mounting groove is provided on the main lifting beam, and a first counterweight block slides in the first mounting groove. By sliding the first counterweight block, the position of the first counterweight block on the main lifting beam is adjusted, thereby adjusting the center of gravity of the entire lifting device. A second counterweight block can also be set on the first counterweight block. During adjustment, the weight can be increased as needed, thereby improving the convenience of adjustment.

[0007] Optionally, the main lifting beam is fixed with lifting lugs on its side, and two lifting lugs are provided, which are distributed along the length of the main lifting beam.

[0008] By adopting the above technical solution, two lifting lugs are installed above the main lifting beam, and the lifting lugs are used to connect to the crane.

[0009] Optionally, it also includes a hanging arm, which is L-shaped, with one end of the hanging arm connected to the side of the main lifting beam and forming a hooking groove with the main lifting beam for hooking the pipe pile.

[0010] By adopting the above technical solution, the hanging arm is connected to the main lifting beam to form a hooking groove, which is used to hook the pipe pile, thereby lifting the pipe pile.

[0011] Optionally, the groove wall of the hook groove is provided with an elastic pad.

[0012] By adopting the above technical solution and setting up an elastic pad, the friction with the pipe pile can be increased, and damage to the surface of the pipe pile can be prevented during hoisting.

[0013] Optionally, the lower wall of the hooking groove is an arc-shaped surface, and the opening of the hooking groove corresponding to the arc-shaped surface faces the side away from the lifting lug.

[0014] Optionally, the upper wall of the hook groove is slidably connected to a retaining block in the vertical direction, and the main lifting beam is provided with a driving component to drive the retaining block to slide up and down.

[0015] By adopting the above technical solution, a clamping block is provided. The clamping block is driven by a driving component to slide and thus abut against the surface of the pipe pile, thereby reducing the possibility of the lifting device loosening and improving the stability of the lifting.

[0016] Optionally, the clamping block is a magnetic block.

[0017] By adopting the above technical solution, the clamping block is a magnetic block, which can be attracted to the pipe pile, thereby further reducing the possibility of loosening.

[0018] Optionally, the side of the abutment block away from the main lifting beam is an arc-shaped surface, the arc-shaped opening of the abutment block faces the side away from the main lifting beam, and a silicone pad is provided on the side of the abutment block away from the main lifting beam.

[0019] By adopting the above technical solution, a silicone pad is provided on the clamping block. On the one hand, it can reduce the damage to the surface of the pipe pile. On the other hand, the silicone pad is elastic and can be adapted to the outer wall of pipe piles of different diameters.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. A first mounting groove is provided on the main lifting beam, and a first counterweight block slides in the first mounting groove. By sliding the first counterweight block, the position of the first counterweight block on the main lifting beam is adjusted, thereby adjusting the center of gravity of the entire lifting device. A second counterweight block can also be set on the first counterweight block. During adjustment, the weight can be increased as needed, thereby improving the convenience of adjustment.

[0022] 2. A clamping block is provided, which is driven by a drive component to slide and abut against the surface of the pipe pile, thereby reducing the possibility of the lifting device loosening and improving the stability of the lifting operation. Attached Figure Description
