Description

Technical Field

[0001] This utility model relates to the field of lifting device technology, specifically to an integrated power unit lifting device. Background Technology

[0002] Integrated power unit lifting equipment typically refers to equipment that integrates multiple functional components into a single device or system to achieve specific power transmission and control functions. Integrated power unit lifting equipment usually includes an engine, transmission system, control unit, and related accessories. Because integrated power unit lifting equipment is generally large in size and has a certain weight, it is necessary to use lifting equipment to lift it during maintenance and disassembly.

[0003] A search revealed Chinese patent CN222293368U, which discloses a lifting device for an integrated power unit. The device includes a crossbeam and a front vertical beam. The two ends of the crossbeam are connected to the front and rear vertical beams respectively via bolts. Lifting chains are fixed to one side of the front and rear vertical beams, and hooks are connected to the lower ends of the lifting chains. This technology, by rotating a second bevel gear, allows operators to precisely adjust and indicate the lifting center of gravity of the lifting device, reducing and dispersing direct pressure on the outer casing, minimizing damage to the device housing, and improving lifting efficiency. Bolts can be used to position and limit the rotation of the first connecting block and the crossbeam, and bolts can also be used to position and limit the rotation of the mounting plate of the rear vertical beam and the crossbeam. This facilitates the installation of the front and rear vertical beams on the crossbeam, allowing for the installation of front and rear vertical beams of different specifications, and enabling the lifting device to easily lift integrated power units of different specifications.

[0004] Regarding the aforementioned technologies, the inventor has discovered the following drawbacks: existing lifting devices have fixed shapes and large volumes, which are not only inconvenient to handle but also cannot be adapted to various specifications of prefabricated lifting operations. Furthermore, the lifting points of these devices are mostly limited to two, making them unsuitable for the lifting operations of diverse integrated power device lifting devices. Moreover, the lifting devices are rigid and cannot be adjusted to adapt to various lifting environments. Therefore, an integrated power device lifting device has been proposed to solve the above problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model embodiment provides an integrated power unit lifting device, such as... Figure 1-4 As shown, it includes a vertical lever arm 1, which is bolted to a horizontal lever arm 2. An extension lever arm 3 is slidably disposed on the inner side of the horizontal lever arm 2. The horizontal lever arm 2 is sleeved on the outer side of the extension lever arm 3 and fixed by a positioning stud 21. Both the horizontal lever arm 2 and the extension lever arm 3 have through holes for the positioning stud 21 to pass through. By sleeved on the outer side of the extension lever arm 3, the horizontal lever arm 2 allows the position of the extension lever arm 3 to be adjusted on the inner side of the horizontal lever arm 2. By adjusting the connection length between the horizontal lever arm 2 and the extension lever arm 3, the device to be lifted can be better matched.

[0026] Both the lateral lever arm 2 and the extension lever arm 3 have through holes that match each other. The positioning pin 21 passes through and is fixed in the hole to control the length of the lateral lever arm 2 and the extension lever arm 3. The lateral lever arm 2 and the extension lever arm 3 can be quickly fixed by connecting them through the positioning pin 21. By setting holes on the surface of the lateral lever arm 2 and the extension lever arm 3, the lateral lever arm 2 and the extension lever arm 3 can be fixed by the positioning pin 21 inserted at different positions.

[0027] A first traction chain group 4 is provided at the upper end of the vertical lever arm 1, a second traction chain group 5 is provided at the upper end of the horizontal lever arm 2, and a third traction chain group 6 is provided at the upper end of the extension lever arm 3. Each of the three lever arms, the vertical lever arm 1, the horizontal lever arm 2, and the extension lever arm 3, at their respective ends, is provided with an end face connecting plate 10. The hanging chain assembly 8 is connected to the lower end of the end face connecting plate 10 through a connecting ring 81. The first traction chain group 4, the second traction chain group 5, and the third traction chain group 6 are all connected to the upper end of the end face connecting plate 10. By providing connecting plates 10 at the end faces of the vertical lever arm 1, the horizontal lever arm 2, and the extension lever arm 3, it is easier and faster to connect the vertical lever arm 1, the horizontal lever arm 2, and the extension lever arm 3 to the upper and lower mechanisms.

[0028] The connecting plate 10 at the end face of the transverse lever arm 2 has a through hole at its center. When the extension lever arm 3 passes through the transverse lever arm 2, it extends through one end of the connecting plate 10. By setting a through hole at the center of the connecting plate 10 corresponding to the transverse lever arm 2, the extension lever arm 3 can pass through, making the extension lever arm 3 have a wider range of movement and a greater range of length adjustment for the transverse lever arm 2 and the extension lever arm 3.

[0029] The first traction chain group 4, the second traction chain group 5, and the third traction chain group 6 are all fitted with a suspension ring 7 at their upper ends. The first traction chain group 4, the second traction chain group 5, and the third traction chain group 6 have the same structure and all include a hook 41. The upper end of the hook 41 is fixedly connected to a traction chain 42. The upper end of the traction chain 42 passes through an adjusting shell 43, which is used to lock the traction chain 42. The upper end of the adjusting shell 43 is connected to the suspension ring 7 through a ring. By setting the first traction chain group 4, the second traction chain group 5, and the third traction chain group 6, the vertical lever arm 1, the horizontal lever arm 2, and the extension lever arm 3 can be lifted quickly. By setting the vertical lever arm 1, the horizontal lever arm 2, and the extension lever arm 3 into a T-shape, the device to be lifted will not overturn or tilt after being lifted, making the lifting process more stable.

[0030] The lower ends of the vertical arm 1, the horizontal arm 2, and the extension arm 3 are all equipped with chain assemblies 8. The lower ends of the chain assemblies 8 are connected to hooks 9. The chain assemblies 8 include connecting rings 81. The connecting rings 81 of the three sets of chain assemblies 8 are connected to the vertical arm 1, the horizontal arm 2, and the extension arm 3 respectively by bolts. The surface of the connecting rings 81 is connected to a chain lock shell 82. The inner side of the chain lock shell 82 passes through the hooking chain 83. The surface of the chain lock shell 82 has a locking shaft for locking the hooking chain 83. The hook 9 is fixedly connected to the bottom end of the hooking chain 83. By setting the chain lock shell 82, the length of the hooking chain 83 can be freely adjusted and fixed after adjustment. The hook 9 is more convenient to be hooked at various anchor points on the surface of the device to be lifted.

[0031] Working principle: In use, first adjust the length between the lateral lever arm 2 and the extension lever arm 3 according to the specifications of the power integration device. After the extension lever arm 3 is set to the appropriate position, use the positioning pin 21 to insert into the holes of the lateral lever arm 2 and the extension lever arm 3 to fix the combined length of the two. Adjust the length of the traction chain 42 by removing the bolts on the inside of the adjusting shell 43. After the length of the traction chain 42 is adjusted, use bolts to fix the traction chain 42 to the inside of the adjusting shell 43. Connect the first traction chain group 4, the second traction chain group 5, and the third traction chain group 6 to the connecting plate 1 of the vertical lever arm 1, the lateral lever arm 2, and the extension lever arm 3 respectively through the hook 41. On the surface of the device, the upper ends of the first traction chain group 4, the second traction chain group 5, and the third traction chain group 6 are attached to the power integrated device via the suspension ring 7. The lifting equipment is attached to the suspension ring 7 to lift and pull the first traction chain group 4, the second traction chain group 5, and the third traction chain group 6. The hook 83 is pulled to adjust the position of the hook 9 and attach it to the power integrated device to be lifted. The length of the hook 83 is fixed by setting the chain lock shell 82, and the hook 83 is fixed to the connecting plate 10 on the end face of the vertical arm 1, the horizontal arm 2, and the extension arm 3 via the connecting ring 81. The power integrated device is lifted by raising the lifting equipment.
