[0035] The following is a clear and complete description of the technical solution of this utility model. Obviously, the embodiments described are part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without making any creative efforts are within the scope of protection of this utility model.

[0036] Example

[0037] See attached Figure 1-9 , a wall column reinforcement cage lifting sling, comprising:

[0038] The steel cage body 10 has a rectangular cross section, and a plurality of reinforcement frames 11 are welded inside the steel cage body 10 and distributed along its length. A reinforcement plate 111 and a reinforcement rod 112 are welded to the four corners of the reinforcement frame 11. The addition of the welded reinforcement frames 11 inside the steel cage body 10 can not only improve the overall load-bearing capacity of the steel cage body 10, but also facilitate horizontal and vertical lifting.

[0039] The horizontal hanging assembly 20 includes a horizontal hanging beam 21, two first hanging ears 22 fixed to the top of the horizontal hanging beam 21 at intervals by bolts, a first shackle 23 installed on the first hanging ear 22, a first lifting rope 24 connecting the two first shackles 23, a plurality of trapezoidal hanging ear plates 25 fixed to the horizontal hanging beam 21 at intervals along the length direction of the horizontal hanging beam 21, second shackles 26 symmetrically installed at the bottom of both ends of the hanging ear plates 25, and a second lifting rope 27 connected to the second shackle 26 at the top;

[0040] The vertical hanging assembly 30 includes a vertical hanging beam 31 perpendicular to the length direction of the steel cage body 10, two third hanging ears 32 welded at intervals on the top of the vertical hanging beam 31, a third shackle 33 installed on the third hanging ear 32, a third hanging rope 34 connecting the two third shackles 33, two fourth hanging ears 35 welded at intervals on the bottom of the vertical hanging beam 31, a fourth shackle 36 installed on the fourth hanging ear 35 and a fourth hanging rope 37 connected to the fourth shackle 36 at the top; wherein, the third hanging ear 32 is arranged along the length direction of the vertical hanging beam 31, and the fourth hanging ear 35 is located directly below the third hanging ear 32 and perpendicular to the length direction of the vertical hanging beam 31; the vertical hanging beam 31 is an I-beam; reinforcing ribs are welded between the third hanging ear 32, the fourth hanging ear 35 and the vertical hanging beam 31.

[0041] When the rebar cage body 10 is hoisted horizontally, the bottom of the second hoisting rope 27 is connected to the reinforcement frame 11 inside the rebar cage body 10; when the rebar cage body 10 is hoisted vertically, the bottom of the fourth hoisting rope 37 is connected to the reinforcement frame 11 inside the rebar cage body 10. It should be noted that when the rebar cage body 10 is hoisted vertically, the vertical hoisting assemblies 30 are installed at the top and bottom of the rebar cage body 10.

[0042] In this embodiment, the horizontal hanging beam 21 is composed of multiple I-shaped steels 211, and a fixing plate 212 is welded at both ends of the I-shaped steel 211. Two adjacent I-shaped steels 211 are fixed together by bolts; the ear plate 25 is fixed to the fixing plate 212 by bolts. It should be noted that the spacing between two adjacent reinforcement frames 11 in the steel cage body 10 corresponds to the length of the I-shaped steel 211 of the horizontal hanging beam 21, so that during horizontal lifting, the bottom of the two second lifting ropes 27 on each lifting ear plate 25 is connected to a reinforcement frame 11; at the same time, it is convenient to select a suitable number of I-shaped steels 211 according to the length of different steel cage bodies 10 and assemble them into a horizontal hanging beam 21; in addition, bolt holes are provided on both ends of the top of the I-shaped steel 211 and the fixed plates 212 welded at both ends, and bolt holes are also provided on the bottom of the first lifting ear 22 and the lifting ear plate 25, so that it is convenient to fix the first lifting ear 22 to the top of the horizontal hanging beam 21 by bolts, and to fix the lifting ear plate 25 to the fixed plate 212 by bolts.

[0043] During use, a steel frame is used to tie the wall column reinforcement to form a rectangular cross-section steel cage body 10. A welded reinforcement frame 11 is added to the steel cage body 10 according to the design, and reinforcement plates 111 and reinforcement rods 112 are welded to the four corners of the reinforcement frame 11. A crane is used, with its hook hooked on the first lifting rope 24. The entire horizontal lifting assembly 20 is hoisted to the position of the steel cage body 10 to be lifted using the first lifting rope 24. The bottom of the second lifting rope 27 is then connected to the reinforcement frame 11 inside the steel cage body 10. The crane is then lifted and hoisted with the help of the horizontal lifting assembly 20 to the finished steel cage storage area or a transfer flatbed truck.

[0044] When switching from horizontal to vertical lifting, two cranes are required to lift the cage 10 off the ground. Specifically, the hook of the first crane is hooked onto the fourth lifting rope 37 of a vertical lifting assembly 30. Using the fourth lifting rope 37, the entire vertical lifting assembly 30 is lifted to one end of the cage 10 to be lifted. Similarly, the hook of the second crane is used to lift a vertical lifting assembly 30 to the other end of the cage 10 to be lifted. The bottoms of the fourth lifting ropes 37 on the two vertical lifting assemblies 30 are connected to the reinforcement frame 11 in the corresponding positions within the cage 10. The first crane slowly and evenly lifts one end of the cage 10 while keeping the hook of the second crane stable. The cage 10 is gradually rotated 90°, thus converting the cage 10 to a vertical position. The fourth lifting rope 37 on the second crane, which is connected to the cage 10, is then removed from the cage 10 and lifted to the hoisting equipment storage location. Then, the reinforcement cage body 10 is vertically hoisted by means of the first crane, thereby completing the hoisting operation from horizontal hoisting to vertical hoisting.

These descriptions are not intended to limit the present invention to the precise forms disclosed, and it is apparent that many modifications and variations are possible in light of the foregoing teachings.
