[0002] In the steel structure manufacturing industry, platforms with large main body dimensions and small main structural profile specifications are relatively common, such as photovoltaic platforms. During the overall hoisting process of such structures, due to the weak overall structural strength, many lifting points are often required to be set up and multiple cranes are used to work together to meet the structural strength requirements. This method is inefficient and wastes crane resources. Therefore, it is necessary to design a tooling to improve hoisting efficiency and save crane resources. Utility Model Content

[0015] like Figure 1 、 Figure 2 As shown, a lifting frame of a platform structure includes a main pipe 1 arranged on both sides, a plurality of tie pipes 2 are arranged between the two main pipes 1, the tie pipe 2 and the main pipe 1 are connected by a connecting component, the connecting component includes a connecting plate 3, a through hole 4 for the main pipe 1 to pass through is provided on the connecting plate 3, and a plurality of lifting ear holes are provided on the connecting plate 3. The lifting ear holes include an upper lifting ear hole 5 provided at the upper end of the connecting plate 3 for connecting to the crane hook head, and a lower lifting ear hole 6 provided at the lower end of the connecting plate 3 for connecting to the platform structure. Multiple lifting ear holes can be provided as needed.

[0016] A heavy plate 7 is provided outside the lifting lug hole to increase the load-bearing capacity.

[0017] The connecting plates 3 are all oriented toward the center of the hoisting frame, and the connecting plates 3 and the main pipe 1 are welded together through a plurality of reinforcing ribs 8 .

[0018] A reinforcing plate 9 for improving the connection strength is welded at the intersection of the ribbed tubes 2 . The connection points between two adjacent ribbed tubes 2 and the main tube 1 are located on both sides of the connecting plate 3 .

[0019] When using:

[0021] Each shackle is connected to a wire rope of corresponding specifications (the length of the wire rope needs to be calculated and determined in advance);

[0022] The other ends of the eight steel ropes are connected to the hook of a crane;

[0023] Lift the crane. After the hoisting frame is suspended in the air, observe whether the eight steel wire ropes above the hoisting frame are all tensioned. If so, proceed to the next step. If not, drop the hook and take measures (such as adding shackles) to adjust the length of the steel wire ropes until the hoisting frame is suspended in the air and the eight steel wire ropes above are all tensioned.

[0026] The other ends of the eight steel cables are connected to the lifting points at the corresponding positions on the platform structure itself through shackles;

[0027] When the crane is lifting, wait until all supports under the platform structure are off the ground, stop lifting, and observe whether the eight steel wire ropes under the frame are all tensioned. If so, proceed to the next step; if not, drop the hook and take measures (such as adding shackles, etc.) to adjust the length of the steel wire ropes until the platform is suspended in the air and all eight steel wire ropes above are tensioned.

[0028] Lift the platform to the target location and complete the lifting.
