[0037] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0038] like Figure 1 As shown, this embodiment is a lifting device structure for disassembling and reassembling a gearbox and engine, including a lifting device assembly and an auxiliary alignment assembly. The lifting device assembly includes a mother ring 1, which is connected to a crane hook. The mother ring 1 is looped around two daughter rings 2, each of which is connected to two chains 3. The other end of each chain 3 is connected to a length adjustment mechanism 4, and the other end of the length adjustment mechanism 4 is connected to another chain 3. The other end of the other chain 3 is connected to a hook 31. Ring buckles 32 are connected at the points where the daughter rings 2, chains 3, length adjustment mechanisms 4, and hooks 31 intersect. Each ring buckle 32 includes an upper ring and a lower ring, the ends of which are hinged. The radius of the mother ring 1's ring surface and cross-sectional radius are both larger than the links of the daughter rings 2 and chains 3, which is obviously larger and easily distinguishable by workers.

[0039] like Figure 2 As shown, the length adjustment mechanism 4 includes a sleeve 41, with teeth 411 at both ends. The sleeve 41 has reverse threads at both ends, each threadedly connected to a ring connector 42. Each ring connector 42 includes a connecting block 421. One side of the connecting block 421 is connected to a threaded rod 422, which threadedly connects to the sleeve 41. The other side of the connecting block 421 has two ears 423, each connected to a pin 424.

[0040] like Figure 3 As shown, the auxiliary alignment component includes two sets of laser pointers 5 and laser targets 6. The laser pointers 5 are set in the bolt holes of the gearbox connecting plate. The laser target 6 is a cylinder with a crosshair target 61 at one end and a thread at the other end that is threaded to the corresponding threaded hole of the engine connecting plate.

[0041] The structure of the gearbox 7 is as follows Figure 4 and 5 As shown, there are two sets of rectangularly distributed vertical M16 bolts at the front end where it connects to the engine, and the two sets of vertical M16 bolts are at the same height and symmetrical along the longitudinal axis of the gearbox 7; there are two sets of rectangularly distributed horizontal M16 bolts at the rear end, and the two sets of horizontal M16 bolts are at the same height and also symmetrical along the longitudinal axis of the gearbox 7. Therefore, this application provides two front fixing plates 8 and two rear fixing plates 9.

[0042] like Figure 6 As shown, the front fixing plate 8 includes a front plate connecting part 81, and the front plate connecting part 81 is connected to a front plate hanging ear part 82. The front plate connecting part 81 and the front plate hanging ear part 82 are perpendicular to each other. The front plate connecting part 81 is provided with four through holes distributed in a rectangular shape.

[0043] like Figure 7 As shown, the rear fixing plate 9 includes a rear plate connecting part 91, and the rear plate connecting part 91 is connected to a rear plate hanging ear part 92. The rear plate connecting part 91 and the rear plate hanging ear part 92 are located on the same plane; the rear plate connecting part 91 is provided with four through holes distributed in a rectangular shape.

[0044] When in use, whether the gearbox and engine are disassembled or assembled, first fix the front fixing plate 8 and the rear fixing plate 9 to the front and rear ends of the gearbox 7 respectively with M16 nuts.

[0045] Then, the main ring 1 of the lifting device assembly is attached to the crane hook. The two sub-rings 2 are connected to chains 3 of different lengths, but the two chains 3 connected to each sub-ring 2 are of the same length. Since the center of gravity of the gearbox 7 is close to the rear end, the shorter chain 3 and sub-ring 2 are connected to the rear fixing plate 9, and the longer chain 3 and sub-ring 2 are connected to the front fixing plate 8.

[0046] When the engine and transmission are working together, the auxiliary alignment component also participates in the work. The laser pointer 5 is opened and placed into the threaded hole of the transmission 7 connecting plate, and the laser target 6 is threadedly connected to the corresponding threaded hole of the engine connecting plate.

[0047] Use a wrench to turn the socket 41 by the wrench 411 to adjust the length of the length adjustment mechanism 4, so as to adjust the height and tilt angle of the gearbox 7. When the laser pointer 5 shines the laser on the crosshair target 61 of the laser target 6, gradually bring the gearbox 7 and the engine closer together. When it is time to connect, remove the laser target 6 and the laser pointer 5, and then complete the disassembly and connection of the gearbox 7 and the engine.

[0048] The technical features of this utility model not described can be implemented by or using existing technology, and will not be repeated here. Of course, the above description is not a limitation of this utility model, and this utility model is not limited to the examples above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model should also be within the protection scope of this utility model.
