Embodiment Construction

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] like figure 1 As shown, the special sling equipped with the hub of the shroud of the present invention includes a T-shaped sling 1 and two double-hole lifting lug plates 2. The T-shaped sling includes a beam 11 and a vertical beam 12. The beam 11 of this embodiment The vertical beams 12 are all frame-shaped welded steel structural parts, and the horizontal beams 11 and the vertical beams 12 can also be cast steel parts. Since the beam 11 has to bear the overall weight of 17-18 tons with the hub 3 of the shroud installed, a frame-shaped welded steel structure with high strength is used. The vertical beam 12 is a welded steel structure with webs 121 on both sides, several rib plates 122 in the middle, and a bottom plate 123 at the bottom. The upper end of the vertical beam 12 is provided with a hoisting hole 124. Six fastening bolts and nuts 13 pass...

Abstract

The invention discloses a special hanger with guide cover wheel hub. The special hanger comprises a T-shaped hanger and two double-hole lug plates, wherein the middle part of a cross beam of the T-shaped hanger is fixedly connected with the lower end of a vertical beam; the upper end of the vertical beam is provided with a hanging hole; and the two double-hole lug plates are provided with two hanging holes respectively. The turning and hanging method of the invention comprises the following steps of: 1) vertically hanging the cross beam into a manhole of the wheel hub through a top hole of a guide cover, and transversely turning the cross beam; 2) fixedly connecting the vertical beam and the middle part of the cross beam to form the T-shaped hanger and fixing the two double-hole lug plates on the wheel hub respectively; 3) connecting a main hook and sling and a secondary hook and sling with corresponding holes of the T-shaped hanger and the two double-hole lug plates respectively; 4) vertically hanging the guide cover wheel hub; 5) turning over the guide cover wheel hub; and 6) hanging a manual hoist crane on the main hook and sling to adjust the inclination angle of axis of the wheel hub, thereby aligning central lines of a connecting surface of the wheel hub and an end face of a main shaft. The special hanger improves the safety and the efficiency for the turnover of the wheel hub and reduces the labor intensity.

Description

technical field [0001] The invention relates to a special sling for wind turbine components, in particular to a special sling for hoisting a hub equipped with a diversion cover, and a flipping hoisting method using the sling, belonging to the technical field of hoisting appliances . Background technique [0002] As a green new energy source without carbon dioxide emissions, wind power is being used more and more widely. The wind turbine impeller is an important component that converts wind energy into mechanical energy. The wind turbine impeller consists of blades and hubs that form 120° with each other. The shroud, the hub with the shroud weighs 17-18 tons. During the final assembly of the factory, the hub must be turned over, and the axis of the hub must be adjusted so as to be docked with the main shaft. The matching connection of the shroud. The existing wheel hub hoisting and turning methods mainly include the following two methods, which are basically used for hoist...
