Single-blade mounting hanging tool for fan blade

Abstract

The invention discloses a single-blade mounting hanging tool for a fan blade. The single-blade mounting hanging tool is characterized in that a longitudinal shaking mechanism is arranged on a main beam, two transverse shaking mechanisms are arranged at the two ends of the main beam in a sleeving mode correspondingly, each clamping mechanism is connected with the corresponding transverse shaking mechanism through an end transverse beam and comprises the end transverse beam, an upper supporting seat structure, a bottom beam, two lower supporting seat structures and a opening and closing device,one end of each end transverse beam is connected to the upper end of a vertical beam in an integrated mode, the upper end of each upper supporting seat structure is connected with the corresponding end transverse beam, and each bottom beam is of an L-shaped structure; and one end of each bottom beam is hinged to the lower end of the corresponding vertical beam, the lower ends of the two lower supporting seat structures are arranged on the corresponding bottom beam, each opening and closing device is arranged on the hinge joint side face of the corresponding end transverse beam and the corresponding bottom beam, and each cable wind mechanism is connected to the corresponding end transverse beam on the same side. According to the single-blade mounting hanging tool, each upper supporting seatstructure can be adjusted at an upper horizontal moving rail of the corresponding end transverse beam, each lower supporting seat structure can be adjusted at a lower horizontal moving rail of the corresponding bottom beam, the adaptive adjustment can be conducted according to the blades of different models, the whole machine control is convenient, and the maintenance is simple.

Description

Technical field [0001] The present invention relates to the technical field of installation hangers for wind blades, in particular to the technical field of clamping mechanisms for installation hangers for wind blades. Background technique [0002] At present, as people pay more attention to environmental protection, the state has issued a series of incentive policies and measures to promote the development of wind power. China has made great progress in the development and utilization of wind energy. The single-unit capacity of wind turbines is also increasing. It has not kept up with the speed of industry development, especially the installation equipment of the impeller, which in turn restricts the large-scale fan. The diameter of the impeller of a fan with a single unit capacity of 3.5MW or more has exceeded 140m. The general installation of the impeller requires larger installation equipment and construction sites. At the same time, as the diameter of the impeller increases,...

AI Technical Summary

Problems solved by technology

[0002] At present, as people pay more attention to environmental protection, the country has issued a series of incentive policies and incentives to promote the development of wind power. China has made great progress in the development and utilization of wind energy. It is increasingly unable to keep up with the speed of industry development, especially the installation equipment of the impeller, which in turn restricts the large-scale of the fan

The diameter of the fan impeller with a single unit capacity above 3.5MW has exceeded 140m. The overall installation of the commonly used impeller requires larger installation equipment and construction sites. At the same time, as the diameter of the impeller increases, the overall windward area will also double. The construction environment of the wind farm (mainly wind speed) virtually prolongs the installation period of the wind turbine and increases the installation cost

[0003] In addition, the existing wind power single-blade spreaders can only be installed horizontally, or can only be installed obliquely but can only adapt to one type of blade, and need to adjust the counterweight again to adapt to other types, and the adapted type The difference should not be too large, so that multiple adjustments are required when hoisting different types of blades in the same wind field, which puts forward higher requirements for the safety of construction operations, and also increases the construction period, which is not conducive to the economy of wind power project construction
