Description

Technical Field

[0001] This utility model relates to the field of hoisting equipment technology, and in particular to a hoisting device for offshore wind turbine bases. Background Technology

[0002] Offshore wind turbine bases, also known as offshore wind turbine bases, are devices used to support offshore wind turbine generator sets. They are a key component of offshore wind power technology and are mainly divided into two categories: fixed and floating. Typically, they consist of a boom, wire rope drum, geared motor, and base. The structure is bulky and cannot be flexibly disassembled and reassembled. The disassembly and maintenance of the wire rope drum is time-consuming, which affects the performance of the equipment.

[0003] The prior art CN210710444U discloses a crane for a base platform of an offshore wind turbine, including a wire rope drum assembly, a pin shaft, a boom assembly, a support boom assembly, a geared motor, a height limiter, a wire rope drum, a wire rope, and a wire rope maintenance window. The wire rope drum assembly is connected to the boom assembly via a pin shaft, and the support boom assembly is connected to the wire rope drum assembly via a pin shaft, and also to the boom assembly via a pin shaft. The structures can be quickly separated, enabling rapid assembly and disassembly of the crane. The geared motor and the height limiter are fixed on both sides of the wire rope drum assembly. The output shaft of the geared motor drives the wire rope drum and the height limiter to rotate, tightening and releasing the wire rope to achieve lifting and lowering actions. A wire rope maintenance window is provided on one side of the wire rope drum assembly to facilitate the replacement and maintenance of the wire rope, thereby improving the efficiency of the equipment.

[0004] In normal use, the geared motor and height limiter are fixed on both sides of the wire rope drum assembly. The output shaft of the geared motor drives the wire rope drum and height limiter to rotate, tightening and releasing the wire rope to achieve the lifting and lowering action. In the current technology, when lifting wind turbine bases at sea, it is inconvenient for the equipment to be adjusted according to the location of the wind turbine base, making it inconvenient for the equipment to lift wind turbine bases in different positions, thus affecting the lifting effect of the equipment on the motor base.

[0007] The rotating component includes a driven wheel and an adjusting component. The driven wheel is rotatably connected to the base and fixedly connected to the turntable. The adjusting component is connected to the driven wheel and to the base.

[0008] The adjusting component includes a main wheel and an adjusting motor, wherein the main wheel meshes with the driven wheel; the adjusting motor is fixedly connected to the base, and the output shaft of the adjusting motor is connected to the main wheel.

[0009] The winding component includes a drive roller and a drive motor. The drive roller is rotatably connected to the frame and connected to the steel cable. The drive motor is fixedly connected to the frame, and the output shaft of the drive motor is connected to the drive roller.
