[0037] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0038] Embodiment 1

[0039] Refer to Figure 1 , an embodiment provided by the present utility model: a simple lifting ring for a reinforcement cage, including a sleeve 2 with internal threads provided on the inner side thereof, and external threads provided on the outer side of the top of the main reinforcement at the corner of the reinforcement cage 3. The sleeve 2 is threadedly connected to the outer side of the top of the main reinforcement at the corner of the reinforcement cage 3, and a round steel lifting ring 1 is fixedly connected to the outer side of the sleeve 2 by welding to ensure the connection strength between the round steel lifting ring 1 and the sleeve 2. During installation, the sleeve 2 is sleeved onto the top of the main reinforcement at the four corners of the reinforcement cage 3, and the sleeve 2 is rotated so that the internal threads of the sleeve 2 are connected to the external threads of the top of the main reinforcement at the corner of the reinforcement cage 3, and the sleeve 2 is fixed to the top of the main reinforcement at the corner of the reinforcement cage 3. Then, the steel wire rope of the lifting device is passed through the inside of the round steel lifting ring 1, and then the lifting device is started to lift the reinforcement cage 3.

[0040] Using the main reinforcement of the reinforcement cage 3 as the lifting point for hoisting, compared with the traditional method of using stirrups as the lifting point, the reinforcement cage 3 is more evenly stressed during hoisting, and the number of overall binding and fixing points between the main reinforcement and the reinforcement cage 3 is much higher than the number of binding points between a single stirrup and the reinforcement cage 3, which is more firm and can effectively reduce the risk of the reinforcement cage 3 falling apart during hoisting.

[0041] Embodiment 2

[0042] Refer to Figures 2 - 3, the applicant found that in addition to using the above-mentioned thread to install the sleeve 2 on the top of the main reinforcement at the corner of the steel reinforcement cage 3, other connection methods can also be used. For example, the sleeve 2 is sleeved on the outside of the top of the main reinforcement at the corner of the steel reinforcement cage 3 to achieve the installation of the sleeve 2 and the steel reinforcement cage 3. The specific installation structure is as follows: on both sides of the inner wall of the sleeve 2, there are openings 7, the openings 7 are set as arc-shaped structures, and the axis of the openings 7 coincides with the axis of the sleeve 2.

[0043] On the outer side wall of the top of the main reinforcement at the corner of the steel reinforcement cage 3, two convex blocks 5 are welded and fixed. The convex blocks 5 are set as arc-shaped structures, and the axis of the convex blocks 5 coincides with the axis of the main reinforcement at the corner of the steel reinforcement cage 3. At the bottom of the front and rear ends of the inner wall of the sleeve 2, there are grooves 8, and the grooves 8 are communicated with the openings 7. The width of the grooves 8 is the same as the width of the convex blocks 5.

[0044] Press the sleeve 2 downward along the axial direction of the main reinforcement of the steel reinforcement cage 3. The convex block 5 cooperates with the groove 8 to make the convex block 5 slide up and down inside the groove 8. When the convex block 5 slides into the groove 8, rotate the sleeve 2 to make the convex block 5 enter the opening 7 inside, and connect the sleeve 2 and the steel reinforcement cage 3.

[0045] On the side wall of the sleeve 2, there is a through hole. On the outside of the convex block 5, there is a slot 6. An insertion rod 4 is inserted inside the slot 6. One end of the insertion rod 4 passes through the through hole on the side wall of the sleeve 2, and the outer side wall of the insertion rod 4 is in close contact with the inner side wall of the slot 6. There is sufficient friction between the two, and the insertion rod 4 will not fall out of the slot 6 inside.

[0046] After connecting the sleeve 2 and the steel reinforcement cage 3, pass the insertion rod 4 through the through hole on the sleeve 2 and insert it into the slot 6 on the convex block 5 to fix the convex block 5, so as to prevent the sleeve 2 from rotating due to external force after being connected to the steel reinforcement cage 3 and causing the convex block 5 to withdraw from the opening 7 inside.

[0047] Press the sleeve 2 downward along the axial direction of the main reinforcement of the steel reinforcement cage 3. The convex block 5 cooperates with the groove 8 to make the convex block 5 slide up and down inside the groove 8. When the convex block 5 slides into the groove 8 and reaches the top of the groove 8, rotate the sleeve 2 to make the convex block 5 enter the opening 7 inside, align the slot 6 on the convex block 5 with the through hole on the sleeve 2, and then pass the insertion rod 4 through the through hole on the sleeve 2 and insert it into the slot 6 inside to fix the sleeve 2 to the top of the main reinforcement at the corner of the steel reinforcement cage 3. Hang the hook of the lifting device inside the round steel lifting ring 1, and then start the lifting device to lift the steel reinforcement cage 3 for hoisting; after the hoisting of the steel reinforcement cage 3 is completed, the hook of the lifting device can be removed from the round steel lifting ring 1, and the insertion rod 4 is pulled forcefully to take the insertion rod 4 out of the slot 6 on the convex block 5, and then rotate the sleeve 2 to make the convex block 5 coincide with the groove 8, and pull the sleeve 2 upward to remove the sleeve 2 from the top of the main reinforcement at the corner of the steel reinforcement cage 3.

[0048] By hoisting the steel cage 3 in the above manner, it is possible to avoid deformation of the stirrups due to the excessive weight of the steel cage 3 when the hoist hook of the hoisting equipment is hung on the stirrups of the steel cage 3 for hoisting.

[0049] Example 3

[0050] Reference Figures 4 - 5 , which is different from the second embodiment in that: in this embodiment, the protrusion 5 is set as an annular structure and is fixed to the outer side of the top of the main reinforcement at the corner of the steel cage 3 by welding. A fixing ring 10 is sleeved on the outer side of the sleeve 2. The fixing ring 10 can slide up and down along the axial direction of the sleeve 2 on the outer side of the sleeve 2. A rotating seat is fixed on the outer side of the bottom of the sleeve 2 along the axial direction. A rotating shaft is fixedly installed in the middle of the side of the hook 9 facing the sleeve 2. The rotating shaft is rotatably connected to the rotating seat. The bottom end of the hook 9 is clamped on the outer side of the protrusion 5. The side of the top of the hook 9 facing the sleeve 2 is set to a downwardly inclined structure, and the distance from the top of the inclined structure of the hook 9 to the outer side wall of the sleeve 2 is greater than the width of the fixing ring 10, so that the fixing ring 10 can squeeze the hook 9 downward, so that the hook 9 can rotate outward.

[0051] A through hole is provided on the fixing ring 10, and a slot 6 is provided on the outside of the sleeve 2. An insertion rod 4 is inserted into the slot 6. One end of the insertion rod 4 passes through the through hole on the fixing ring 10. The insertion rod 4 passes through the through hole on the fixing ring 10 and is inserted into the slot 6 to fix the fixing ring 10 on the outside of the sleeve 2.

[0052] The sleeve 2 is put on the outer side of the top of the main reinforcement at the corner of the steel cage 3, and the fixing ring 10 is slid downward so that the fixing ring 10 squeezes the hook 9. Under the squeezing of the fixing ring 10, the top of the hook 9 rotates outward around the rotating seat, so that the bottom of the hook 9 rotates inward around the rotating seat and is clamped on the outside of the protrusion 5. Then, the insertion rod 4 is inserted into the slot 6 through the through hole on the fixing ring 10 to fix the fixing ring 10, so as to fix the sleeve 2 to the top of the main reinforcement at the corner of the steel cage 3 for hoisting the steel cage 3.

[0053] When disassembling, pull the insertion rod 4 hard to make the insertion rod 4 withdraw from the slot 6, then slide the fixing ring 10 upward, and pull the hook 9 outward to separate the hook 9 from the protrusion 5, pull the sleeve 2 upward, and remove the sleeve 2 from the steel cage 3.

[0054] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
