The base 23 is provided with a threaded hole. The threaded holes of the base 23 on the two beam arms 11 are screwed to the two ends of the screw. When the screw rotates, the sliding seats on the two beam arms approach or move away from each other to adjust the distance between the lifting rings on the two slides.

[0042] See also Figure 2 and Figure 3 As shown, the free end of the beam arm 11 is formed with an ear plate 13. The screw rod is rotatably mounted between the ear plates 13 of the two beam arms 11.

[0046] In this embodiment, the locking member is a pin.

[0047] The present invention provides a method for hoisting a cross-shaped hanging beam for wind-resistant hoisting of an assembled building, comprising the following steps:

[0048] S1. Based on the size of the component to be hoisted, adjust the distance between the sliding seats 2 on the two colinear beam arms 11 of the cross beam 1 so that the position of the lifting ring 22 on the cross beam 1 is compatible with the position of the lifting point of the component to be hoisted.

[0049] S2. Install the cross beam 1 on the sling of the lifting machinery.

[0050] S3, lower the sling so that the lifting ring 22 is close to the component to be lifted.

[0051] S4. Install the component to be hoisted on the four lifting rings 22 of the cross beam 1 through the connecting rope, so that the component to be hoisted is stably hung on the lifting rings 22.

[0052] S5. Retract the sling to lift the component to be lifted to the target floor.

[0053] The cross-shaped lifting beam for wind-resistant lifting of prefabricated buildings of the present invention is provided with a cross beam and a protective frame, wherein a first sliding hole and a second sliding hole are opened on the beam arm of the cross beam, and a sliding seat in the first sliding hole, and the use of an adjusting piece can realize the adjustment of the distance between the two lifting rings. Since the requirements for lifting equipment are different in different projects, the design of adjustable spacing enables the same set of equipment to be applied to a variety of scenarios, thereby improving the versatility and flexibility of the equipment. At the same time, by adjusting the spacing between the lifting rings, it can better adapt to prefabricated components of different sizes and shapes, thereby ensuring the stability and safety of the lifting process.

[0054] The cross-shaped hanging beam for wind-resistant hoisting of assembled buildings of the present invention is provided with second sliding holes on both sides of the cross beam, the ear seat of the sliding seat protrudes from the second sliding holes, a locking plate is formed on the outside of the second sliding hole, and the ear seat bears the locking plate on the outside of the second sliding hole of the cross beam. When the lifting ring bears the weight, the weight is not only supported by the adjusting member, but also dispersed to the entire cross beam through the locking plate, thereby reducing the risk of structural instability caused by local overload.

[0055] Since it is difficult to ensure the stability of the sliding seats at both ends only by relying on the adjusting parts during the actual lifting process, locking plates are arranged on both sides of the cross beam, and a first locking hole is reserved in the vertical direction of the locking plates protruding from the ear seat of the sliding seat. Through the cooperation between the ear seat of the sliding seat and the locking plate, the sliding seat can be firmly positioned on the cross beam, thereby effectively preventing the sliding seat from shaking or displacing during the lifting process and improving the stability of the entire structure.

[0056] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the above features are replaced with (but not limited to) technical features with similar functions disclosed in the present application.
