[0052] The method for improving the load efficiency of the lifting tool and facilitating clamping in the small end port of the hub is various, and optional implementation manners are further provided in the embodiment.

[0053] Embodiment two:

[0054] As shown in Figure 1 , Figure 2 In the embodiment, the device meeting the above requirements comprises:

[0055] a lifting ring 1, a connecting shackle, one end of the connecting shackle being connected with the connecting ring 2, a sling, the sling being arranged at the other end of the connecting shackle, a quick detachable shackle 5, the quick detachable shackle 5 being connected with the sling, a lifting piece 6, the lifting piece 6 being in a strip shape, the length of the lifting piece 6 being greater than the diameter of the small end port of the hub, the lifting piece 6 comprising: a lifting part, the lifting part being arranged at both ends of the lifting piece 6, the lifting part being provided with an inclined surface, the inclined surface being arranged on the upper end surface of the lifting piece 6, a connecting part, the connecting part being arranged on the upper end surface of the lifting piece 6, the connecting part being located between the two lifting parts, the connecting part being provided with a mounting hole, and the mounting hole being connected with the quick detachable shackle 5.

[0056] Specifically, the connecting shackle comprises a connecting ring 2 and a butterfly buckle 3, which is used to improve the connection strength during use, reduce the risk of chain entanglement during lifting, and improve the wear condition to improve the service life of the lifting tool, and prevent the sharp end of the lifting hook from reducing the service life of the chain 4.

[0057] Specifically, the sling is a chain 4, which further improves the service life of the sling.

[0058] Specifically, the sling comprises two, and the number of the connecting shackles and the connecting parts corresponds to the number of the slings.

[0059] Specifically, the included angle between the two slings is 20-40°, and the double chains 4 and the lifting angle ensure sufficient rated load.

[0060] Specifically, the included angle part formed by the inclined surface and the lower end surface of the lifting piece 6 is provided with a round corner, which prevents damage to the paint on the inner wall of the wind power hub and causes corrosion.

[0061] Specifically, the hoisting part is provided with a protective layer, and the protective layer is composed of pearl wool to reduce damage to the force bearing part of the lifting appliance and prevent damage to the paint on the inner wall of the wind power hub, thereby preventing corrosion.

[0062] Specifically, the butterfly buckle 3 comprises: two U-shaped rings I, the two U-shaped rings I are oppositely arranged; and a pin shaft, the pin shaft is used for connecting the two U-shaped rings I, and is used for reducing the risk of winding of the two chains due to shaking during hoisting.

[0064] Specifically, the profile of the inclined surface is pre-set, the profile of the inclined surface is fitted with the inner cavity of the small end port of the hub, and the force borne by the hoisting part 6 is further reduced.

[0065] Specifically, the hoisting part 6 is further provided with an adjusting belt, both ends of the adjusting belt are wound around both ends of the hoisting part 6, and the position of the hoisting part 6 when passing through the small end port of the hub is adjusted by pulling the adjusting belt.

[0066] Specifically, the width of the hoisting part is smaller than the width of the hoisting part 6, so that the quick dismounting buckle 5 can be connected with the mounting hole of the hoisting part, and the width of the hoisting part 6 can reach sufficient strength.

[0067] The remaining devices and effects of the embodiment are the same as those of embodiment one.

[0068] By setting the hoisting part 6 as a strip, the hoisting part 6 is more easily inserted into the small end port of the hub; at the same time, the length of the hoisting part 6 is greater than that of the hub, so that the hoisting part 6 can be clamped in the hub; then, the hoisting part is provided with an inclined surface, the moving load of the lifting appliance is increased, the service life of the lifting appliance is improved, and the lifting appliance can be easily inserted into the small end port of the hub; the quick dismounting buckle 5 is provided for easy installation and dismounting, which further reduces the step of clamping the lifting appliance in the inner cavity of the small end port of the hub, and solves the problems of low service life and high labor intensity of the lifting belt with the protective pad in the prior art.

[0069] The lifting device uses a lifting ring 1 in conjunction with two chains 4 to form a two-pronged lifting mechanism. The other end of the chain 4 is connected to the mounting hole of the connecting part via a shackle, allowing the lifting device to be loosened during loading and unloading by releasing one end of the shackle and smoothly inserting it into the small port of the wheel hub. After reinstalling the shackle at the other end, the device is returned to the lifting state for lifting operations. This design reduces the difficulty of manual operation while ensuring the service life of the lifting device. The design of the inclined surface, connecting ring 2, and butterfly buckle 3 further increases the moving load capacity of the lifting device, extending its service life. Each set of lifting devices can reduce sling wear by tens of thousands of yuan per year. Furthermore, the lifting device has a simple structure and is easy to manufacture.

[0070] Example 3:

[0071] like Figure 3 As shown, in this embodiment, the apparatus that satisfies the above requirements further includes:

[0072] The lifting component is also provided with a support part 609, which is provided on both sides of the lifting component and is perpendicular to the lifting component. The end of the support part 609 is provided with a limiting part 610.

[0073] The supporting arm 7 has two through holes on both sides and a slope at one end. The slope fits the shape of the upper end of the inner cavity of the workpiece. The supporting arm 7 has a receiving cavity for placing the supporting part 609.

[0075] The positioning bolt 701 passes through the support arm 7 and is fixedly installed on the support arm 7 by a threaded connection with the positioning nut 702. The positioning bolt 701 is always blocked by the limiting part 610.

[0076] The remaining devices and their effects in this embodiment are the same as in Embodiment 2.

[0077] By adding two movable auxiliary booms to the lifting component, the stability of the lifting device during lifting is increased while ensuring that the lifting component can enter the workpiece. This also distributes the force on the workpiece during lifting, reducing damage to the workpiece, without affecting the difficulty of operation for personnel, and increasing the service life of the lifting device.

[0078] Example 4:

[0079] In this embodiment, a method for using a hoisting device for a wind turbine hub is also provided, including the following steps:

[0080] The hoisting device is provided to connect the hoisting component 6 to the wheel hub;

[0081] A lifting device is provided, which is connected to the hoisting device;

[0083] Specifically, the method of using the hoisting device for the wind turbine hub further includes the following steps:

[0084] Place and loosen one of the two quick-release buckles 5, so that the lifting component 6 passes through the small port of the hub, and install the loosened quick-release buckle 5 in the inner cavity of the hub, so that the loosened quick-release buckle 5 connects the sling to the lifting component 6.

[0085] The lifting component 6 is engaged and lifted so that its inclined surface fits into the inner cavity of the small port of the wheel hub, thereby lifting the wheel hub to a predetermined height.

[0086] The wheel hub is lifted and transported to a predetermined lifting point using the lifting device 6, and then lowered to the predetermined lifting point at a predetermined speed.

[0087] Loosen and lower the lifting component 6 so that it is located in the inner cavity of the wheel hub, and begin to loosen one of the two shackles;

[0088] The hoisting component 6 is retrieved and lifted, so that it leaves the inner cavity of the wheel hub through the small port of the wheel hub, thus completing the hoisting of the wheel hub.

[0089] Specifically, the lifting of the hoisting component 6 is achieved by connecting it to the crane hook.

[0090] Specifically, the lifting of the hoisting component 6 also includes controlling the position of the hoisting component 6 through the adjusting belt to prevent the hoisting component 6 from damaging the inner wall of the wind turbine hub.

[0091] By loosening one of the two quick-release buckles 5, the lifting component 6 can switch between two different postures, horizontal and vertical, when engaging the wind turbine hub. Then, by manually adjusting the lifting component 6 during lifting, the position of the lifting component 6 is properly engaged in the inner cavity of the small port of the wind turbine hub, which improves the lifting efficiency and prevents damage to the wind turbine hub during lifting.
