Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Example

[0028] Please refer to Figure 1-Figure 4 , which is a schematic diagram of the structure of a foldable aerial hanging basket in an embodiment of the utility model;

[0029] This embodiment provides a foldable aerial hanging basket, comprising:

[0030] At least four support columns 10, the four support columns 10 are parallel to each other and arranged in an array to form a rectangular structure, and the tops of the four support columns 10 are provided with hanging members 11;

[0031] A plurality of round steel groups are arranged in parallel and at intervals along the length direction of the support columns 10, and the round steel groups are movably arranged through the four support columns 10 so that the aerial hanging basket can be folded in the length direction; wherein the portion of the round steel group located between two adjacent support columns 10 has a gap for construction;

[0032] The bottom plate 30 is connected between the bottommost round steel groups, and the bottom plate 30 is connected to the inclined sides of the round steel groups when the aerial hanging basket is folded.

[0033] Next, the foldable aerial basket of this exemplary embodiment will be further described.

[0034] In some embodiments of the present application, the four support columns 10 are arranged to form a stable rectangular structure, so that the hanging basket maintains a high degree of safety when in use and provides a place for operators to stand. A hanging member 11 is provided on the top of the four support columns 10, and the hanging member 11 is used to hang the hanging basket on the bridge steel bars, thereby fixing the hanging basket. The hanging member 11 can be a hook for easy disassembly and assembly.

[0035] As a preferred embodiment, the support column 10 may be made of a square steel tube or a round steel tube. In the embodiment of the present application, a 3 cm square steel tube is preferably used, and the square steel tube is provided with a through hole for the round steel group to pass through.

[0036] In some embodiments of the present application, several of the above-mentioned round steel groups are rectangular and arranged in parallel along the length direction of the support column 10, and the round steel groups are movably inserted into the four support columns 10 so that the aerial hanging basket can be folded in the length direction; wherein, the portion of the round steel group located between two adjacent support columns 10 has a notch for construction. By arranging the round steel group to be movably inserted into the square steel pipe, the round steel group can rotate in the through hole of the square steel pipe, so that several round steel groups can be tilted in the length direction (height direction) of the hanging basket, thereby realizing the folding of the hanging basket, narrowing its width, and facilitating the lowering from the narrow expansion joint space for construction, and also facilitating storage after folding. Several round steel groups have a notch on one side, so that a construction station is formed on one side of the hanging basket. When the construction personnel are working, the notch surface is used as a construction position, which is convenient for the construction personnel.

[0037] As a preferred embodiment, the round steel group includes a first round steel 21, a second round steel 22 and a third round steel 23. The first round steel 21 is movably arranged between two adjacent support columns 10 and extends outward. The second round steel 22 and the third round steel 23 are both U-shaped, and one end of the second round steel 22 and the third round steel 23 are respectively connected to the two ends of the first round steel 21, and the other ends of the second round steel 22 and the third round steel 23 are respectively movably arranged in the remaining two support columns 10. Figure 1 As shown, the first round steel 21 moves through two adjacent support columns 10, and the second round steel 22 and the third round steel 23 are respectively located at a point outside the support column 10, so that the first round steel 21 can rotate between two adjacent support columns 10, while only the ends of the second round steel 22 and the third round steel 23 can rotate between the corresponding support columns 10. Therefore, when the hanging basket is folded, the surface where the first round steel 21 is located is used as the rotation driving surface, and the surface where the second round steel 22 and the third round steel 23 are located is used as the inclined folding surface, and the notch surface is pulled toward the surface where the first round steel 21 is located to achieve folding. Among them, the corners of the second round steel 22 and the third round steel 23 are all arc transitions, which are easy to fold and improve safety in use.

[0038] As a preferred embodiment, the second round steel 22 and the third round steel 23 are respectively connected to the first round steel 21 at one end or at both ends of the first round steel 21. By providing the limit stopper, the first round steel 21 can be prevented from moving along its own axial direction between the support columns 10, thereby affecting the folding. Specifically, the limit stopper can be provided with a plurality of ring-shaped stoppers, or can be directly provided as a ring-shaped stopper.

[0039] In some embodiments of the present application, the bottom plate 30 is connected between the bottommost round steel groups, and the bottom plate 30 is connected to the inclined sides of the round steel groups when the aerial hanging basket is folded. That is, the bottom plate 30 is connected between the second round steel 22 and the third round steel 23 at the bottom, and the bottom plate 30 is movably connected to the first round steel 21. Specifically, a collar 31 can be provided on the opposite sides of the bottom plate 30, and is simultaneously sleeved on the bottom plate 30 and the first round steel 21, so that when folding, the bottom plate 30 can rotate on the first round steel 21 as the second round steel 22 and the third round steel 23 are tilted and folded, so that the folding is flexible. The bottom plate 30 is used to carry workers and provide support. The bottom plate 30 is made of steel plate or steel frame and has a high bearing capacity.

[0040] As a preferred embodiment, triangular wheels 12 are provided at the bottom of the two support columns 10 connected to the first round steel 21. By providing the triangular wheels 12 at the bottom, the steps can be automatically crossed, which is convenient for manual transportation on uneven sites, and the triangular wheels 12 are only provided at the bottom of the support columns 10 corresponding to the first round steel 21. When transporting, the hanging basket can be folded or tilted to push, which is more convenient and quick.

[0041] As a preferred embodiment, an openable and closable flexible connecting belt 13 is provided between the two support columns 10 connected to the second round steel 22 and the third round steel 23. That is, an openable and closable flexible connecting belt 13 is provided between the two support columns 10 on one side of the gap, which can be closed during construction to improve the construction safety of the construction workers, and the conveniently opened structure facilitates the construction workers to enter and exit.

[0042] Furthermore, one end of the flexible connection belt 13 is fixedly connected to one of the support columns 10, and the other end of the flexible connection belt 13 is detachably connected to the other support column 10. Specifically, a hook can be provided on one of the support columns 10, and a hanging ring can be provided on one end of the flexible connection belt 13. The hook and the hanging ring are detachably connected, which is convenient for opening and closing, thereby improving the efficiency of construction workers.

[0043] Furthermore, at least one flexible connecting belt 13 is provided, and a plurality of flexible connecting belts 13 may be provided at intervals, and the design may be made according to actual needs.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
