[0005] A balance beam is arranged laterally from left to right. Each end of the balance beam has a balancing lifting position, and the balancing lifting position is equipped with a main lifting rope and an adapter.

[0006] A truss short arm is provided below the adapter one. The truss short arm is arranged perpendicular to the balance beam. Short arm lifting positions are provided at both the front and rear ends of the truss short arm. Support ropes are provided on the short arm lifting positions and connected to the adapter two. The upper end of the support ropes is connected to the adapter one.

[0007] The truss long arm is located below the balance beam and is arranged parallel to the balance beam. Long arm lifting positions are provided at both ends of the truss long arm, and the long arm lifting positions are connected to the adapter two at the rear end of the short arm lifting positions.

[0008] Preferably, the adapter includes an adapter body, the top of which is provided with a hinge hole, the hinge hole being movably connected to the balance hoisting position via a connecting pin, and the main hoisting rope being suspended from the connecting pin.

[0009] The bottom of the adapter body has two front-to-back connecting holes, which are respectively connected to two support ropes for suspension.

[0031] Example 1

[0032] like Figures 1 to 6 As shown, this embodiment discloses a large-tonnage steel frame integral lifting device, characterized by including a balance beam 1, two truss short arms 5, and a truss long arm 9. The balance beam 1 is arranged laterally, with a balance lifting position 2 at both ends of the balance beam 1. The balance lifting position 2 is equipped with a main lifting rope 3 and an adapter 4, and the main lifting rope 3 at both ends is connected to the hook above. The truss short arms 5 are correspondingly arranged below the adapter 4, and are arranged perpendicular to the balance beam 1. The front and rear ends of the truss short arms 5 are equipped with short arm lifting positions 6, and the short arm lifting positions 6 are equipped with support lifting ropes 7 connected to an adapter 8. The upper end of the support lifting rope 7 is connected to the adapter 4. The truss long arm 9 is located below the balance beam 1 and is arranged parallel to the balance beam 1. The left and right ends of the truss long arm 9 are equipped with long arm lifting positions 10, and the long arm lifting positions 10 are connected to the adapter 8 at the rear end of the short arm lifting positions 6.

[0033] In this embodiment, each adapter 8 is provided with an end rope 11 that is attached to the hoisting component 12. Depending on the shape of the hoisting component 12, the number of end ropes 11 can be multiple.

[0034] like Figure 3 and 4 As shown, adapter 4 includes adapter body 401. The top of adapter body 401 has a hinge hole 402, which is movably connected to the balance lifting position 2 via a connecting pin 403. The main lifting rope 3 is suspended from the connecting pin 403. The bottom of adapter body 401 has two front-to-back connecting lifting holes 404. Shackles can be installed on the two connecting lifting holes 404, and the connecting lifting holes 404 are suspended from the support rope 7 via the shackles. The shackles facilitate the disassembly of the support rope 7 from the connecting lifting holes 404.

[0035] like Figure 5 and 6 As shown, adapter 2 8 includes adapter body 2 801. Both the upper and lower ends of adapter body 2 801 are provided with hinge holes 2 802, and the axes of the two hinge holes 2 802 are arranged perpendicular to each other.

[0036] Among them, the hinge hole 802 located at the top is movably connected to the short boom hoisting position 6 through the connecting pin 803, and the lower end of the support rope 7 is suspended and connected to the connecting pin 803.

[0037] Among them, the hinge hole position 2 802 located below is provided with the connecting pin 3 804; the long boom position 10 and the rear end of the short boom position 6 are movably connected to the connecting pin 3 804; the end rope 11 is suspended and connected to the connecting pin 3 804.

[0038] In this embodiment, the short arm 5 and the long arm 9 of the truss are integral structures.

[0039] In this embodiment, two support legs 101 are provided on the balance beam 1 to facilitate placement on the balance beam 1.

[0040] In this embodiment, the bottom of the truss arm 9 is provided with multiple auxiliary suspension points 901, and the auxiliary suspension points 901 can also be suspended and connected to the hoisting component 12 via the end rope 11.

[0041] Core advantages of this invention:

[0042] (1) The lifting system of the present invention is mainly composed of a balance beam 1, a short truss arm 5, a long truss arm 9, a first adapter 4, a second adapter 8, and several key components such as pins. Among them, the main function of the first adapter 4 and the second adapter 8 is to flexibly adjust the direction of force to adapt to the mechanical requirements under different lifting scenarios, while the first connecting pin 403, the second connecting pin 803, and the third connecting pin 804 are used to ensure the stable connection between the components. The main lifting rope 3, the support lifting rope 7, and the lifting lugs, as key load-bearing components of the lifting system, are made of materials with a high safety factor to ensure safety during the lifting process.

[0043] (2) The truss arm 5 and the balance beam 1 are connected by the support cable 7 and the adapter 4; the adapter is used to adjust the direction of force, and finally achieve a reliable connection with the top of the lower hoisting unit column, so as to ensure that the force is evenly transmitted during the hoisting process and reduce the risk of local stress concentration. Among them, the support cable 7 can be in the form of a hoisting belt.

[0044] (3) Steering connectors are installed on both sides of the balance beam 1. The main function of the steering connectors is to change the direction of force so that the force on the slings can be reasonably distributed and the stability of the hoisting operation can be enhanced. At the bottom of the steering connectors, they are connected to the support sling rope 7 by shackles. The use of shackles is not only convenient and quick, but also ensures the reliability of the connection and facilitates quick assembly and disassembly during hoisting operations.

[0045] (4) The short arm 5 and the long arm 9 of the truss are connected by adapter 2 8. Adapter 2 8 enables the entire hoisting truss system to better adapt to the force requirements at different angles. Two lifting points are arranged at both ends of the long arm 9 to facilitate the balanced distribution of load during the hoisting process. The end cable 11 is connected to the lower pin of adapter 2 8, and then connected to the top of the lower hoisting unit column through a shackle to form a complete force transmission path, ensuring the stability of the hoisting unit during the lifting, transportation and positioning process.

[0046] (5) The lower surface of the truss arm 9 is arranged with auxiliary lifting points 901 according to the actual steel frame size and hoisting requirements. Each lifting point is precisely calculated and designed to ensure balanced force during hoisting. Shackles are used to connect the slings to the lifting points, and then shackles are used to connect the slings to the top of the lower hoisting unit's side column. This connection method is not only easy to operate, but also has high safety and reliability, which can effectively ensure the smooth progress of hoisting operations and reduce safety risks during hoisting.

[0048] like Figure 7 As shown, in this embodiment, the truss short arm 5 adopts a multi-segment assembly structure, and adjacent short arm connecting segments are fixed together by bolt assemblies. The remaining structure in this embodiment is the same as in Embodiment 1.
