Description

Technical Field

[0001] The utility model relates to the technical field of wind blade detection, in particular to a supporting device for wind blade detection. Background Art

[0002] Ceiling fans usually have three blades, table fans usually have five blades, and the cross-section of common fan blades is generally curved. The width and angle of the fan blades are designed, depending on the load power of the motor. If you ignore the motor power and only look at the speed, you should also look at the angle of the blades. If the angle of the blades is the same, of course the wider the blade, the stronger the wind. Moreover, the design and production of the blades are regular symmetrical structures, so that a uniform and stable wind source can be generated. Common leaf fans include three-leaf fans, four-leaf fans, five-leaf fans, double-layer fans, etc.

[0003] The fan blades need to be inspected during production, and can be assembled and used only after passing the inspection. The existing inspection generally places the fan blades directly on the workbench for inspection, and this inspection method can only inspect the fan blades once, and the fan blades are not placed firmly enough during inspection, and loading and unloading are also more troublesome. In addition, the fan blades need to be inspected for multiple items, so it is inconvenient to inspect the next item on the fan blades, which brings trouble to the inspection and affects the inspection efficiency. In addition, the fan blades need to be moved to different inspection areas when inspecting different items. The traditional method is generally manual transportation, which is time-consuming and labor-intensive, and has low work efficiency and is not convenient for inspection and maintenance. In view of the above problems, a fan blade support device for rapid inspection of fan blades is proposed. Utility Model Content
