Problems solved by technology

Fan blades are usually installed from one side during installation, due to the special surface shape of the fan blade itself (such as Image 6 The middle black part), the spreader can only clamp one posture of the blade, and three blades are installed repeatedly from the same position. At this time, the hub needs to be rolled by 120° (such as figure 1 shown), this installation method is time-consuming and labor-intensive, which affects the overall installation efficiency of wind turbines

Abstract

The invention discloses a sling dedicated to wind power equipment. The sling comprises a sling gantry hanging bracket, a main frame and a clamping part, wherein the gantry hanging bracket is positioned at the top of the main frame; the clamping part is arranged on the main frame and comprises a switchable shape follow-up surface module, an upper compressing module and a jacking device; one end ofthe jacking device is fixedly connected with the main frame; the other end of the jacking device is movably connected with the switchable shape follow-up module; and the upper compressing module is positioned above the switchable shape follow-up module and is movably connected with the main frame. Compared with the traditional technology, the sling has the posture adjusting function and greatly improves compatibility of multiple postures in fan blade mounting.

Description

technical field [0001] The invention relates to the technical field of hoisting equipment, in particular to a special hoisting tool for wind power equipment. Background technique [0002] The blades of wind turbines are the most basic and critical components of wind turbines. They affect the conversion efficiency of wind energy and directly affect the annual power generation of generators. They are an important part of wind energy utilization. Fan blades are usually installed from one side during installation, due to the special surface shape of the fan blade itself (such as Figure 6 The middle black part), the spreader can only clamp one posture of the blade, and three blades are installed repeatedly from the same position. At this time, the hub needs to be rolled by 120° (such as figure 1 As shown), this installation method is time-consuming and laborious, which affects the overall installation efficiency of the wind turbine. Contents of the invention [0003] The inv...
