Description

Technical Field

[0001] This utility model belongs to the technical field of wind turbine nacelle covers, and specifically relates to a flip-over hoisting tool. Background Technology

[0002] The nacelle is one of the main components of a wind turbine generator. Traditional nacelle structures typically consist of three large panels—left, right, and top—which could be easily installed by workers using overhead cranes during production. However, with the development of large-megawatt wind turbine generators, the overall size of the nacelle has increased significantly. Nacelle designs now incorporate multiple panels, resulting in smaller individual panels but a greater number of panels, thus requiring frequent installation and removal.

[0003] Traditional hoisting tools have a relatively simple structure. After hoisting, they are mostly turned over manually, which is laborious and inefficient for workers. They can easily damage the product when hoisting the sheet and pose safety risks.

[0004] Currently, there are some existing tilting hoisting tools, but they may all have certain problems, such as complex or unstable fixed component structures, inconvenient operation, or unsuitability for fixing the nacelle cover. Some tilting component structures are also relatively complex, and the size of the hoisting component is fixed and cannot be adjusted. Summary of the Invention

[0005] This invention provides a flip-up hoisting tool that can solve the problems pointed out in the background art.

Detailed Implementation

[0028] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0029] Example: Figure 1-5 As shown in the figure, the present invention provides a flip-up hoisting tool, including a hoisting assembly 1, a rotating assembly 2, and a fixing assembly 3. The fixing assembly 3 is rotatably connected to both sides of the hoisting assembly 1 through the rotating assemblies 2 on both sides. The fixing assembly 3 includes an L-shaped fixing seat 31 and an upper pressure plate 32 hinged to the L-shaped fixing seat 31. The L-shaped fixing seat 31 and the upper pressure plate 32 form a limiting groove. The upper pressure plate 32 is provided with a locking assembly. An angle locking assembly is provided between the upper pressure plate 32 and the L-shaped fixing seat 31. The position of the upper pressure plate 32 is locked by the angle locking assembly.

[0030] Specifically, the locking assembly includes a locking bolt 34 and a locking washer 35. The contact surface between the locking washer 35 and the workpiece 5 may be provided with a rubber gasket to protect the product surface.

[0031] Specifically, the upper pressure plate 32 is hinged to the L-shaped fixed base 31 via the hinge 33. The upper pressure plate 32 is flipped upward to facilitate the insertion of the workpiece 5. After the workpiece 5 is inserted, the hinge 33 is returned to its original position and locked by the locking bolt 34.

[0032] The angle locking component is an angle adjustment plate component.

[0033] The angle adjustment plate assembly includes an arc-shaped angle plate 61 disposed on the upper pressure plate 32 and a guide locking assembly. The arc-shaped angle plate 61 is provided with an arc-shaped guide hole 62. The guide locking assembly includes a threaded sleeve 63 fixed on an L-shaped fixing seat 31 and a locking screw 64 that cooperates with the threaded sleeve 63.

[0034] In some embodiments, the upper pressure plate 32 is a magnetic upper pressure plate, and the hanger assembly 1 is provided with a magnet 36 at the corresponding position. After the magnetic upper pressure plate is flipped upward, it is attracted by the magnet 36, which facilitates the placement of the workpiece 5. The magnet 36 is specifically set on the movable column 16, and the angle locking assembly is an angle adjustment plate assembly.

[0035] Specifically, the rotating assembly 2 includes a rotating handle 21, a meshing gear set 22 (which may consist of a large gear and a small gear), a rotating shaft 23, and an angle locking element 24. The rotating handle 21 is connected to the power input end of the gear set 22. Specifically, the rotating handle 21 and the small gear of the gear set 22 are fixed together by a square key 38, which serves as the power input end. The end of the rotating handle 21 is provided with a cotter pin. The rotating shaft 23 and the large gear of the gear set 22 are fixed together by a square key 38 and a C-shaped retaining ring 39, which serves as the power output end. This transmission structure can reduce the force during the overturning process, saving workers' energy. The rotating shaft 23 is connected to the power output end of the gear set 22. The shaft end is provided with a cotter pin 40. The rotating shaft 23 is rotatably connected to the hanger assembly 1. The angle locking component 24 locks the angle of the rotating shaft 23. Gear fixing seats 26 are provided on both sides of the hanger assembly 1. The outer ends of the gear set 22 and the rotating shaft 23 are rotatably connected to the gear fixing seats 26. The outer end of the rotating shaft 23 is provided with a screw. The angle locking component 24 is a lock nut, which locks the angle.

[0036] In some embodiments, the rotating shaft 23 is rotatably connected to the hanger assembly 1 via a one-way bearing 25 and a rolling bearing 37. The one-way bearing 25 can control the rotation to be in only one direction during hoisting, avoiding the safety risks of bidirectional rotation of the product in the air.

[0037] Specifically, the hanger assembly 1 includes a length-adjustable main crossbeam and length-adjustable uprights connected to both sides of the length-adjustable main crossbeam, each capable of length locking. The length-adjustable main crossbeam includes a fixed main crossbeam 11 and two movable main crossbeams 12 on both sides. The movable main crossbeams 12 are slidably connected to the fixed main crossbeam 11. The movable main crossbeam 12 has several first connecting holes 13 along its length direction. The fixed main crossbeam 11 has a first pin 14. The length-adjustable uprights include a fixed upright 15 and a lower movable upright 16. The upper end of the fixed upright 15 is connected to the movable main crossbeam 12, and the lower end of the fixed upright 15 is slidably connected to the movable upright 16. The movable upright 16 is connected to a rotating assembly 2 and a fixed assembly 3. The movable upright 16 has several second connecting holes 17 along its length direction. The fixed upright 15 has a second pin 18.

[0038] In some embodiments, a sling 41 and a ring 42 are connected above the hanger assembly 1. The sling 41 can be a herringbone sling.

[0039] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
