[0024] When in use, if it is necessary to lift materials with small differences in length, width and height, such as bagged cement (it is necessary to ensure that the materials cannot pass through the penetration of the bottom plate 2), first unload the hanging basket, then put the materials on the net bag, then connect the safety hook of the crane or tower crane with the lifting mechanism, and then lift the materials so that the materials are in the net bag, and then lift them. If it is necessary to lift longer materials such as steel bars or I-beams, put the hanging basket back and make the basket lie horizontally, then insert one end of the materials into the hanging basket, and make the other parts on the net bag, and then use the lifting mechanism to lift the net bag, so that the materials tend to be in a vertical state and are bound in the net bag, thereby improving adaptability. Since the hanging basket supports the materials, not only the safety is improved, but also the lateral space occupied during the movement is greatly reduced, so it can move in a narrow space. In summary, its applicability is improved.

[0025] The net bag includes a main sling 8, a No. 1 main bracket 9, a No. 2 main bracket 10, a No. 3 main bracket 11, and a guide mechanism.

The bottom plate 2 is hinged with multiple main slings 8 at equal angles up and down. Each of the main slings 8 is fixed with a No. 1 main bracket 9, a No. 2 main bracket 10, and a No. 3 main bracket 11 in sequence and equidistant from the inside to the outside of the bottom plate 2. The No. 1 main bracket 9, the No. 2 main bracket 10, and the No. 3 main bracket 11 are respectively installed with guide mechanisms.

Similarly, when the lifting mechanism releases the main sling 8, the No. 1 auxiliary sling 13, the No. 2 auxiliary sling 14 and the No. 3 auxiliary sling 15, and then the net bag is manually spread out, it can be refilled.

[0027] The guiding mechanism includes a sub-bracket 16, a threading tube 17, and a pulley 18.

The penetration part of the bottom plate 2 is threadedly connected with a limiting ring 34. When the limiting ring 34 is threadedly connected to the bottom plate 2, it can only be detached from the top but not from the bottom. The upper part of the plug block 31 can abut against the top of the limiting ring 34. The limiting ring 34 is hinged with a toggle plate 35 at the top and bottom. The toggle plate 35 naturally hangs down under the action of gravity and shrinks outside the inner circle contour of the limiting ring 34.

[0032] When the lifting device 31 is in a state of being lifted up, the locking plate 35 is in a state of being lifted up, and the locking plate 35 is in a state of being lifted up, so that the locking plate 35 is not in a state of being lifted up, and the locking plate 35 is in a state of being lifted up, so that the locking plate 35 is ...

[0034] Furthermore, when the hanging basket is not used, the penetration of the bottom plate 2 can be filled by installing the support seat 36, thereby improving the carrying capacity of small-volume materials. When the hanging basket is used, the support seat 36 is removed and the hanging basket is installed. When the hanging basket or the support seat 36 is used, the mounting seat 39 is installed in the corresponding support tube 37, and then the fan 46 is controlled to work, so that the streamer 48 can be blown to make it rise. At this time, the aerial position of the net bag can be pulled and adjusted to facilitate lifting or placement. By properly rotating and braking the servo motor 41 through radio control, the streamer 48 can be moved circumferentially, so that it is easy to be caught by workers in different positions, and when the workers use the streamer 48 to adjust the position of the net bag, they do not need to be in close contact, thereby improving safety.

[0035] The connecting piece includes a accommodating shell 50, a guide shell 51, a lower servo motor 52, a supporting shaft 53, a planar volute spring 54, a roller 55, an air inlet pipe 56, and an air blowing pipe 57.

[0036] Furthermore, by controlling the servo motor 52 to rotate forward and reverse, the ribbon 48 can be tightened and released. During the tightening process, the roller 55 can cause the plane volute spring 54 to undergo elastic deformation. When releasing the ribbon 48, the roller 55 can rotate due to the elastic deformation of the plane volute spring 54, so that the ribbon 48 can be extended from the guide housing 51 to the outside, which is convenient for workers to hold.
