Description

Technical Field

[0001] The utility model relates to the technical field of hangers, in particular to a single-blade hanger for a fan. Background Art

[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and ultimately outputs alternating current. The generator rotates and generates electricity driven by the wind wheel shaft. When installing the blades, a hoist is required to lift the blades.

[0003] According to a Chinese patent application with patent application number 202123299026.5, a single-blade hoist for a wind turbine is disclosed, comprising a lifting beam, a first hanger, a second hanger, two clamps, two electro-hydraulic push rods and a battery for powering the electro-hydraulic push rods. One end of the lifting beam is hinged to the first hanger through two first shackles arranged at intervals, and the other end is hinged to the second hanger through two second shackles arranged at intervals. The first hanger and the second hanger have a C-shaped opening on the same side, and the two clamps are respectively installed at one of the openings. The first hanger and the second hanger are respectively installed with an electro-hydraulic push rod connected to the corresponding clamp, which is hinged to the first hanger and the second hanger through the shackle, thereby effectively releasing the bending moment generated between the first hanger and the second hanger and the lifting beam, simplifying the structure, and convenient and quick on-site installation; the single-piece transportation dimensions of the hanger and the lifting beam are not over-wide or over-high, which significantly reduces transportation.

[0004] However, the two clamps of the single-blade hanger for a fan are fixed, which makes it inconvenient to adjust the distance between the two clamps according to usage requirements, thus reducing the applicability of the single-blade hanger for a fan. Therefore, we propose a single-blade hanger for a fan. Utility Model Content
