[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application (for ease of description and understanding, hereinafter referred to as...), Figure 2 (The above is described above). All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0021] Please see Figures 1-4 This application provides a technical solution: a hoisting and mounting device for long-shaft forgings, including a hoisting main beam 3. The hoisting main beam 3 has a hollow structure for connecting with an external mounting shaft. The hollow structure of the hoisting main beam 3 not only reduces the overall weight but also improves the flexibility and adaptability of the entire device.

[0022] The main hoisting beam 3 is symmetrically connected to the left and right ends with sleeve cylinders 1.

[0023] In addition, the hoisting main beam 3 evenly distributes the suspension force to the sleeve cylinders 1 on both sides, thereby ensuring the stability and safety of the long shaft forging during the hoisting process.

[0024] The sleeve sleeve 1 enhances the overall stability and strength of the main beam 3 during hoisting, and provides a reliable installation position for the transverse support beam 5. The symmetrical arrangement can effectively disperse the stress generated during hoisting and prevent structural damage caused by excessive local stress.

[0025] A transverse support beam 5 is sleeved between the sleeve cylinders 1.

[0026] The transverse support beam 5 is fixed by the sleeve between the sleeve cylinders 1 and is set parallel to the long shaft forging. It is used to install and arrange the shaft hangers. The multiple linearly arranged shaft hangers can effectively ensure that the long shaft forging remains horizontal during transportation.

[0027] The transverse support beam 5 is arranged parallel to the long shaft forging, and three shaft hangers are evenly arranged on the transverse support beam 5.

[0028] The transverse support beam 5, with three evenly arranged shaft hangers, ensures balanced support for the long shaft forging during hoisting, preventing deformation or damage caused by uneven local stress. This multi-point fixing structure effectively avoids the risk of slippage or falling of the long shaft forging during hoisting, ensuring the safety of personnel and equipment.

[0029] The shaft mounting component includes a mounting sleeve 2, an arc-shaped support 7, and a reinforcing connecting block 4. The arc-shaped support 7 is provided on the outer arc of the mounting sleeve 2, and the end of the arc-shaped support 7 is provided with an inclined straight section.

[0030] Specifically, the hanging sleeve 2 is located on the transverse support beam 5, and it is rotatably mounted on the transverse support beam 5.

[0031] The arc-shaped lifting support 7 is installed on the outer arc of the hanging sleeve 2 to further stabilize the long shaft forging. The arc-shaped lifting support 7 can effectively enhance the supporting force on the long shaft forging and prevent it from sliding or displacing during hoisting.

[0032] A reinforcing connecting block 4 is fixed on the arc-shaped support 7 near the straight section, and a rope hanging sleeve 8 for holding the shaft is provided in the middle position of the reinforcing connecting block 4.

[0033] The reinforcing connecting block 4 is located on the arc-shaped support member 7 near the straight section and is firmly fixed to the arc-shaped support member 7 by welding or other methods. On the one hand, it improves the structural strength of the arc-shaped support member 7, and on the other hand, the reinforcing connecting block 4 also provides a stable mounting point for the rope hanging frame 8, ensuring that the long shaft forging can be effectively gripped during hoisting and preventing any slippage or displacement.

[0034] The rope sling 8 is used for binding and securing long shaft forgings. By connecting the opposing rope slings 8 with ropes and other components, the risk of slippage or falling of the long shaft forgings during hoisting is effectively avoided.

[0035] A pad is also provided on the arc-shaped end of the arc-shaped support component 7.

[0036] Furthermore, the angle between the straight section of the arc-shaped support member 7 and the horizontal plane is 30 to 60 degrees, and it is set obliquely upward.

[0037] The angle of the straight section that slopes upward is between 30 and 60 degrees. The straight section that slopes upward can better hold the workpiece, which helps to keep the long shaft forging fixed in position and avoids sliding or displacement due to gravity, thus enhancing safety.

[0038] Furthermore, an intermediate reinforcing member 6 is provided between the arc-shaped support members 7, and the intermediate reinforcing member 6 is a reinforcing connecting rod that penetrates adjacent arc-shaped support members 7.

[0039] The intermediate reinforcement 6 consists of reinforcing connecting rods that run through adjacent arc-shaped support members 7. This increases the rigidity and stability of the entire device, which is especially important when bearing heavy loads. By firmly connecting adjacent arc-shaped support members 7, the intermediate reinforcement 6 effectively distributes the load applied to each arc-shaped support member, reducing the burden on individual components and thus improving the safety and reliability of the overall structure.

[0040] Furthermore, the pad on the arc-shaped support 7 is also provided with anti-slip texture.

[0041] The pad has anti-slip texture, which increases the friction between the pad and the contact surface with the long shaft forging, preventing unnecessary sliding or displacement during hoisting.

[0042] Furthermore, the transverse support beam 5 is fixed to both sides of the hoisting main beam 3 by connecting blocks.

[0043] Furthermore, an arc-shaped bend hook is provided at the end of the rope hanging bracket 8.

[0044] The curved hook prevents accidental rope slippage to some extent, adding extra safety. It also guides the rope more naturally into the correct fixing position, reducing adjustment time and improving work efficiency.

[0045] Furthermore, the pad is a detachable structure, which facilitates replacement according to long shaft forgings of different diameters.

[0046] When the diameter of the forging is small, it is placed against the outer side of the round forging through a pad to ensure the stability of the forging during hoisting.

[0047] Furthermore, the sleeve 1 is provided with a through hole, in which a hanger shaft is installed.

[0048] The hanger shaft enables effective connection between the main lifting beam 3 and external mounting equipment (such as a crane). The hanger shaft provides the necessary connection points and helps distribute stress generated during lifting, ensuring the safety and stability of the entire installation.

[0049] Furthermore, the mounting sleeve 2 is adjustablely installed on the outside of the transverse support beam 5.

[0050] The adjustable design accommodates long shaft forgings of different sizes, allowing for positional adjustments along the transverse support beam 5 to achieve optimal support.

[0051] Furthermore, the reinforcing connecting block 4 is fixed to the arc-shaped support member 7 by welding.

[0052] In use: The device is transported to an external lifting device via the hanger shaft. The main lifting beam 3 has a hollow structure for engaging with the external hanger shaft. Adjust the position of the hanging sleeve 2 according to the actual dimensions of the long shaft forging, moving it to a suitable location. Select a suitable pad based on the specific diameter of the long shaft forging to be transported, and install it on the arc-shaped end of the arc-shaped support 7. Ensure the anti-slip texture on the pad is in close contact with the surface of the long shaft forging to increase friction and prevent slippage. Hook the rope onto the rope hanger 8, and then place the long shaft forging on the adjusted arc-shaped support 7. Utilize the anti-slip texture on the pad to increase friction and prevent the long shaft forging from sliding or shifting. During lifting, the forging presses down under gravity, applying force to the arc-shaped support 7. The rope, guided by the arc-shaped bend hook, enters the correct fixed position, firmly holding the arc-shaped support 7, thus securing the long shaft forging and completing the lifting of the workpiece.

[0053] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
