[0017] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part: As attached Figure 1 - Appendix Figure 9 As shown, this utility model is a lifting device for an amphibious vehicle, including a lifting sling module, a lifting structure module, and a lifting attachment module. The lifting ring 201 of the sling 2 in the lifting sling module is connected to a lifting rope 202. Each lifting rope 202 is connected to an adjusting chain, one end of which is connected to the lifting rope 202, and the hook at the other end of the adjusting chain is hooked to the lifting rope 202. Each lifting rope 202 is connected to a heavy-duty bow-shaped shackle V6. To address the shortcomings of the prior art, an improved technical solution is proposed. The structure is configured as follows: Figure 1 As shown, the lifting device is divided into four main parts: 1. Lifting sling module, 2. Lifting structure module, 3. Lifting harness module, and 4. Hook module. The lifting sling module includes an electric hoist 1 with adjustable sling length and a sling (four-legged sling) 2. The structure of the sling 2 is as follows. Figure 2 As shown, this consists of a lifting ring 201 and four steel wire ropes. Each of the four steel wire ropes has a sling hook 203 installed at its base for hooking and connecting the lifting structure module, thus enabling the lifting of the amphibious vehicle. Figure 9As shown, the hook module includes a wheel hook 18 and a heavy-duty bow-shaped shackle V6. During lifting, the wheel hook 18 passes through the screw hole onto the wheel hub bolt connecting the amphibious vehicle, and then a nut is locked onto the wheel hub bolt to achieve a reliable connection between the wheel hook and the wheel hub. This lifting method ensures uniform force distribution, and the heavy-duty bow-shaped shackle V6 is located away from the vehicle, preventing damage. The amphibious vehicle lifting device described in this utility model can precisely adapt to the structure of the amphibious vehicle, achieving stable and safe lifting operations, avoiding damage to the amphibious vehicle body during lifting, improving the vehicle's protective performance, and also possessing good versatility, expanding its application range, and reducing costs.

[0018] The amphibious vehicle lifting device also includes a hook module, which comprises a wheel hook 18 and a heavy-duty bow-shaped shackle I 19. The wheel hook 18 is movably connected to the heavy-duty bow-shaped shackle I 19, which has multiple screw holes. During lifting, the screw holes pass through the wheel hub bolts of the amphibious vehicle, and nuts are screwed onto the wheel hub bolts. In this structure, the wheel hook 18 is used to connect to the wheel hub, while the wheel hook 18 is movably hooked to the heavy-duty bow-shaped shackle I 19, which is used to connect to the lifting rope, thus achieving reliable lifting and transfer of the amphibious vehicle.

[0019] The lifting structure module includes two long I-beams 3, two short I-beams 4, and a reinforcing I-beam 5. A lifting rope 202 connects to the corners of the lifting structure module. In this structure, the lifting rope 202 is a chain structure. By adjusting the hooks at the other end of the chain to connect to different lifting rings on the rope 202, the overall length of the rope can be adjusted to meet different length requirements.

[0020] Each long I-beam 3 of the lifting structure module is equipped with a heavy-duty lifting lug 7 near the upper edge, and a heavy-duty bow-shaped shackle II 20 is installed on each heavy-duty lifting lug 7. Each long I-beam 3 of the lifting structure module is equipped with a lifting lug 10 near the lower edge. The above structure, as described... Figure 3 As shown, the lifting structure module has a U-shaped frame structure. Its main structure includes two welded long I-beams 3, two short I-beams 4, and two reinforcing I-beams 5.

[0021] The heavy-duty lifting lug 7 of the lifting structure module is made of Q355 high-strength steel. The lower width of the heavy-duty lifting lug 7 is greater than the upper width, and a reinforcing rod 8 is welded between the heavy-duty lifting lug 7 and the long I-beam 3. Figure 4 , Figure 5As shown, the heavy-duty lifting lug 7 is made of Q355 high-strength steel, with a larger contact area on the bottom surface, making the welded structure more robust. Each heavy-duty lifting lug 7 is placed at the connection point of the I-beam to distribute the force evenly. All eight heavy-duty lifting lugs 7 face the centripetal direction, with the center points of the four diagonals serving as the frame's center of gravity. During lifting, the electric hoist 1 and wire rope 202 are adjusted to ensure the vehicle's center of gravity coincides with the frame's center in the X and Y directions, thus guaranteeing overall stability. There are two lifting lug connecting rods 8 between each lug, used to fix the lugs and increase the welding area. The reinforcing lifting lug 9 serves both to strengthen the frame structure and as a lifting lug. The lifting lug 10 can lift small-tonnage amphibious vehicles.

[0022] Two reinforcing I-beams 5 are welded between two long I-beams 3. Each reinforcing I-beam 5 is close to a corresponding short I-beam 4. A sealing plate 11 is welded to the end of the short I-beam 4. Long reinforcing ribs 12 are L-shaped and are welded to the sealing plate 11 and the long I-beam 3. U-shaped reinforcing ribs 13 are welded between the long I-beams 3, short I-beams 4, and reinforcing I-beams 5. Reinforcing lugs 9 are welded at the joint between the short I-beams 4 and long I-beams 3. The reinforcing lugs 9 are L-shaped and are connected to heavy-duty bow-shaped shackles Ⅲ21. As shown in Figures 6 and 7, after the long I-beams 3 and short I-beams 4 are welded, they are reinforced with L-shaped long reinforcing ribs 12. The sealing plate 11 is welded to the end of the section of the short I-beam 4. The long reinforcing ribs 12, bent into L-shapes, are fastened to the I-beams 3 and short I-beams 4, with one end connected to the sealing plate 11. Finally, they are welded into a whole. U-shaped reinforcing ribs 13 are welded between the long I-beam 3, the short I-beam 4, and the reinforcing I-beam 5. Short reinforcing ribs 14 are welded between the long I-beam 3 and the reinforcing I-beam 5. The reinforcing lifting lugs 9 are designed as L-shaped structures, connecting at the joint between the short I-beam 4 and the long I-beam 3, which can both strengthen the overall frame strength and hook for lifting heavy-duty amphibious vehicles.

[0023] The heavy-duty bow-shaped shackle III 21 connects to the large lifting lug 15 of the lifting fixture module. The large lifting lug 15 connects to the fixture crossbeam 16. Each end of the lower part of the fixture crossbeam 16 has a lifting hole for hooking and connecting to a heavy-duty bow-shaped shackle IV 22. The heavy-duty bow-shaped shackle IV 22 connects to the lifting rope 202. The large lifting lug 15 and the fixture crossbeam 16 are both made of Q355 high-strength steel. The above structure, as described... Figure 8As shown, the large lifting lug 15 on the lifting attachment module is made of Q355 high-strength steel, with a larger contact area on its lower surface, making it more firmly welded to the attachment beam 16. The attachment beam 16 is an I-beam made of Q355 high-strength steel, which is sturdy and durable. The double-hole lifting lug 17 is welded to the lower surface of the attachment beam 16. By adding multiple double-hole lifting lugs 17 at different positions under the attachment beam 16, it can adapt to amphibious vehicles with different wheelbases. The different holes of the double-hole lifting lug 17 can be used to attach heavy-duty bow-shaped shackles IV22, and different types of steel wire ropes can be adapted according to the vehicle's load and external dimensions.
