Abstract
Description
Technical Field
[0001] This utility model relates to the field of blade lifting equipment technology, and in particular to a large wind turbine blade lifting equipment. Background Technology
[0002] Wind turbine blades are one of the core components of wind turbines. Their design directly affects the wind energy conversion efficiency and annual power generation, making them a crucial part of wind energy utilization. Blades are generally lifted and transported using lifting equipment. This lifting equipment is mainly used for large wind turbine blades and is used for single-blade lifting.
[0003] When using the blade lifting device, two lifting ropes are used to lift the blade from both ends of the lifting beam structure. During the lifting process, it is easily affected by parameters such as wind force, which can cause swaying and safety hazards, making it difficult to lift the blade safely and stably. Utility Model Content
[0004] The purpose of this utility model is to provide a large wind turbine blade lifting tool.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A large wind turbine blade lifting device includes a main beam, with a blade root end beam and a blade tip beam fixedly connected to each other on both sides of the main beam, and a pair of circular lifting straps connected to each of the blade root end beam and the blade tip beam.
[0006] Preferably, a hydraulic rod tip is provided at the tip beam of the blade, and a tip pressure plate is provided on the hydraulic rod tip.
[0007] Preferably, the blade root end beam is provided with a hydraulic rod blade root, and the hydraulic rod blade root is provided with a blade root pressure plate.
[0008] Preferably, a pair of unhooking devices are provided on both sides of the leaf root end beam and the leaf tip end beam.
[0009] Preferably, pins are provided inside the end walls on both sides of the blade root end beam and the blade tip end beam, and eye bolts are fixed to the pins, and clasp spring pins are provided on the pins.
[0010] Preferably, both the root end beam and the tip end beam are provided with bow-shaped shackles that are connected to the eye bolts and to the circular slings.
[0011] This utility model has at least the following beneficial effects: On each side of a main beam, there is a blade root end beam and a blade tip beam. Pins, eye bolts, and snap ring pins are arranged inside the blade root end beam and blade tip beam to stabilize the connection of the bow-shaped shackle. The bow-shaped shackle is connected to the circular slings. There are a total of four circular slings to create four lifting points. With four stress points, the lifting is more stable and can effectively prevent slight wind blowing, eliminate swaying, and make the blade lifting safer. Attached Figure Description
