Description

Technical Field

[0001] This utility model relates to the field of wind turbine generators, and in particular to an auxiliary tooling for hoisting wind turbine generator blades. Background Technology

[0002] An existing patent (publication number: CN222138455U) proposes an auxiliary tooling for hoisting wind turbine blades. It includes a device body containing a left frame, a right frame, and an extension section. Both the left and right frames have sling boxes on their outer sides, with hoisting straps connected to their lower ends. The inner sides of both the left and right frames have side blocks with several mounting holes, and fixing bolts are connected to these holes on both sides. The extension section also has side blocks and mounting holes at both ends, connecting it to the left and right frames via these side blocks and mounting holes. However, this device, where "two sets of sling boxes are fixed to the lower ends of the left and right frames respectively," relies on the hoisting straps at the bottom of the frames to hoist the wind turbine blades. After hoisting, if the blade orientation needs to be adjusted, the fixed orientation of the frames may prevent adjustment based on actual needs, thus presenting certain limitations. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of existing technologies by providing an auxiliary tooling for wind turbine blade hoisting. This tooling uses lower and upper clamps inside a hoisting frame to fix the wind turbine blades. During hoisting and installation, if the blade orientation needs adjustment, a worm motor on the upper part of the hoisting platform drives the worm gear to rotate, causing the worm gear to rotate the worm wheel on the upper part of the central shaft. This, combined with the guide wheel on the side of the rotating disc, provides guidance, allowing the wind turbine blades at the lower part of the hoisting frame to have their orientation adjusted according to the actual installation conditions. This increases the adaptability of the equipment.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A wind turbine blade hoisting auxiliary fixture includes a hoisting platform, a hook, a rotating disk, a guide wheel frame, a guide wheel shaft, a guide wheel, a hydraulic device, and an upper clamp. The side of the hoisting platform is fixedly connected to the hook. The hoisting platform has a central shaft groove inside, which is adapted to a central shaft and connected to the central shaft. The central shaft rotates within the central shaft groove. The upper part of the hoisting platform is fixedly connected to a drive box. The drive box has a worm gear groove inside, which is adapted to a worm gear and connected to the worm gear. The worm gear rotates within the worm gear groove. The side of the drive box is fixedly connected to a worm groove, which is adapted to a worm shaft and connected to the worm shaft. The worm shaft rotates within the worm groove and contains a worm that meshes with the worm gear on the side. The side of the drive box is fixedly connected to a worm motor, and the output shaft of the worm motor is fixedly connected to the worm shaft. The lower part of the central shaft is fixedly connected to the rotating disk.

[0006] The side of the rotating disk is fixedly connected to the guide wheel frame, the upper part of the guide wheel frame is fixedly connected to the guide wheel shaft, the guide wheel shaft is adapted to the guide wheel, and the guide wheel shaft is connected to the guide wheel.

[0007] The guide wheel rotates on the side of the guide wheel shaft, the lifting plate has a guide groove inside, the guide wheel rotates on the side of the guide groove, the side of the rotating plate is fixedly connected to the lifting frame, and the upper part of the lifting frame is fixedly connected to the hydraulic device. Beneficial effects

[0008] 1. During the use of this utility model wind turbine blade hoisting auxiliary tooling, the wind turbine blade is fixed by the lower and upper clamps inside the hoisting frame. If the blade orientation needs to be adjusted during hoisting and installation, the worm motor on the upper part of the hoisting platform drives the worm to rotate, which in turn drives the worm wheel on the upper part of the central shaft to rotate. This, along with the guide wheel on the side of the rotating disk, provides guidance, allowing the wind turbine blades under the hoisting frame to be adjusted in orientation according to the actual installation situation, thereby increasing the adaptability of the equipment.

[0009] 2. During the use of this utility model of wind turbine blade hoisting auxiliary tooling, the worm gear motor on the upper part of the hoisting plate drives the central shaft to rotate, which in turn drives the hoisting frame on the side of the rotating plate to rotate. In conjunction with the guide wheel on the side of the rotating plate, the rotating plate rotates and guides the plate on the side of the guide groove. This prevents the central shaft from tilting and getting stuck when the rotating plate is subjected to force on one side, thereby increasing the stability of the equipment.

[0010] 3. During the use of this utility model of wind turbine blade hoisting auxiliary tooling, the worm motor drives the internal worm to drive the worm wheel to rotate. Because the transmission principle of the worm and worm wheel has a self-locking function, the adjusted angle is maintained, thereby enhancing the stability of the equipment.
