[0002] Aircraft outer skin molds are typically large, heavy, and complex in shape, requiring extremely high safety and precision during hoisting. Most existing hoisting devices have fixed structures, making it difficult to flexibly adjust the lifting point positions according to different specifications of aircraft outer skin molds. Because different models of aircraft outer skin molds vary in size, shape, and lifting point distribution, fixed hoisting devices cannot meet diverse hoisting needs. This necessitates frequent changes of hoisting equipment when hoisting different molds, increasing operating costs and time, and reducing production efficiency.

[0003] Therefore, it is necessary to provide a hoisting device for manufacturing aircraft outer skin molds to solve the problems mentioned in the background art. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a hoisting device for manufacturing aircraft outer skin molds, comprising: a hoisting platform, wherein a lifting ring is installed at the center of the top of the hoisting platform, the lifting ring being used to engage with the lifting end of a gantry crane; and upper connecting rings are evenly installed circumferentially on the bottom of the hoisting platform. A positioning ring is provided below the lifting platform, and a lower connecting ring is provided at the top of the positioning ring corresponding to the upper connecting ring. The upper connecting ring and the lower connecting ring are connected by a first cable. The bottom end of the positioning ring is coaxially provided with an annular groove, which is a T-shaped groove. Several slider assemblies are slidably arranged in the annular groove. A second cable is installed at the bottom end of each slider assembly, and a hook is installed at the end of the second cable for attaching the aircraft outer skin mold. The method involves adjusting the position of each slider assembly to hoist aircraft outer skin molds of different specifications.

Detailed Implementation

[0013] Please see Figure 1-3This utility model provides a hoisting device for manufacturing aircraft outer skin molds, including: a hoisting plate 1, a hoisting ring 2 installed at the middle of the top of the hoisting plate 1, the hoisting ring 2 being used to connect with the hoisting end of a gantry crane; and upper connecting rings 4 evenly installed circumferentially at the bottom of the hoisting plate 1. A positioning ring plate 3 is provided below the lifting plate 1. A lower connecting ring 5 is provided at the top of the positioning ring plate 3 corresponding to the upper connecting ring 4. The upper connecting ring 4 and the lower connecting ring 5 are connected by a first cable 6. The bottom end of the positioning ring disk 3 is coaxially provided with an annular groove 7, which is a T-shaped groove. Several slider assemblies 8 are slidably arranged in the annular groove 7. A second cable 9 is installed at the bottom end of each slider assembly 8. A hook 10 is installed at the end of the second cable 9 for attaching the aircraft outer skin mold. A cross plate 13 is fixedly provided on the inner side of the positioning ring disk 3. A cross groove 131 is provided at the bottom end of the cross plate 13. The cross groove 131 has the same specifications as the annular groove 7 and the two are connected.

[0014] Limiting holes 11 are provided on either side of the cross slide groove 131 and the annular slide groove 7. A plurality of limiting holes 11 are evenly provided along the trajectory of the cross slide groove 131 and the annular slide groove 7. A positioning pin 12 is installed in the limiting hole 11 for positioning the slider assembly 8.

[0015] The slider assembly 8 includes: an annular slide plate 81, with a sliding column 82 coaxially mounted at the bottom end of the annular slide plate 81. The annular slide plate 81 and the sliding column 82 are adapted to the specifications of the T-slot and are slidably disposed within the annular slide groove 7 or the cross slide groove 131.

[0016] The different sizes of aircraft outer skin molds are hoisted by adjusting the position of each slider assembly 8.

[0017] Specifically, the lifting plate 1, positioning ring plate 3, cross plate 13, and reinforcing plate 14 are made of Q355 high-strength structural steel to ensure structural rigidity, and the slider assembly 8 is provided with 4 to 8 pieces.

[0018] When hoisting an aircraft outer skin mold, firstly, determine the number of slider assemblies 8 based on the size, weight, and lifting point positions of the aircraft outer skin mold; then, connect the lifting hook of the gantry crane to the lifting ring 2 at the top of the lifting plate 1, ensuring proper connection; next, loosen the positioning pins 12 that fix each slider assembly 8, and push the slider assembly 8 to slide along the circumference of the annular slide groove 7 or the cross slide groove 131, so that each hook 10 is aligned with the preset lifting point of the mold, ensuring that the force on each lifting point is uniform; then, hook each hook 10 into the lifting point of the mold, ensuring that the hooks are fully closed; finally, start the gantry crane, slowly lift the lifting plate 1, and drive the positioning ring plate 3 to rise synchronously through the first cable 6, and after the second cable 9 is stressed, smoothly lift the mold, move it to the target position, and then slowly lower it.

[0019] Furthermore, the outer periphery of the positioning ring disk 3 is provided with a slot 71 corresponding to the annular slide groove 7, for quick loading and unloading of the slider assembly 8.

[0020] Furthermore, multiple lower connecting rings 5 ​​are evenly distributed radially along the positioning ring disk 3, and each lower connecting ring 5 is connected to the upper connecting ring 4 via a first cable 6. The radially distributed multiple lower connecting rings 5, in conjunction with the upper connecting ring 4, expand the stress points of the positioning ring disk 3 from a single circle to multiple intersecting circles, dispersing concentrated stress during lifting and reducing the risk of deformation of the positioning ring disk 3.

[0021] Furthermore, a reinforcing plate 14 is fixedly provided at the top of both the positioning ring disk 3 and the cross plate 13 to improve the connection strength and tensile strength between the positioning ring disk 3 and the cross plate 13.

[0022] In practice, the number of slider assemblies 8 is determined based on the mold's weight, size specifications, and number of lifting points. The slider assemblies 8 are added or removed via the slot 71. Then, the positioning pin 12 is loosened, and the slider assembly 8 is pushed to slide along the annular groove 7 or the cross groove 131, aligning the hooks 10 with each lifting point of the mold. After adjustment, the positioning pin 12 is tightened to position the slider assembly 8. Next, the gantry crane hook is attached to the lifting ring 2 of the lifting plate 1, and it is checked that the hook is properly attached. Then, each hook 10 is attached to the mold lifting point, and the cable buckles are checked for secure fastening, the positioning pin 12 is tightened, and the welds and connections are undamaged. Finally, the gantry crane is started to slowly lift the mold, observing whether it is level. If it is tilted, the position of the positioning pin 12 can be slightly adjusted. Once the mold has moved smoothly to the target position, it is slowly lowered. After the mold is placed securely, the hooks 10 and positioning pins 12 are loosened, and each slider assembly 8 is adjusted to reset.
