Description

Technical Field

[0001] This utility model belongs to the field of lifting ring technology, specifically a lifting ring structure for lifting steel cages. Background Technology

[0002] In existing technologies, to expedite construction, pier reinforcement cages are often hoisted as a whole and installed in sections. The lifting rings are directly welded to the main reinforcement bars of the cage, and the crane lifts the cage by hooking the lifting rings. However, due to potential insecure welding between the lifting rings and the cage, the lifting rings may detach during hoisting due to uneven stress, posing a safety hazard to construction workers and severely impacting the overall construction progress.

[0003] The announcement (CN221796739U) also includes: a U-shaped lifting ring; positioning supports, which are provided in two sets, with one end of each set of positioning supports being fixedly connected to the outer edges of the U-shaped lifting ring corresponding to its U-shaped bend position on both sides.

[0004] The aforementioned method of hoisting steel cages can only perform simple hoisting without any modification to the fixing device. When the steel cage is hoisted and shakes, there is a possibility that the steel bars may fall off, causing the steel cage to fall apart and creating a work hazard. It also cannot be adapted to fix different types of steel bars. If the steel bars are larger than the fixing device, the fixing device must be replaced, which is time-consuming, labor-intensive, and affects work efficiency during use.

[0005] Therefore, a lifting ring structure for hoisting steel cages is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a lifting ring structure for hoisting steel cages. It has the advantages of being able to use a threaded tightening device to prevent the steel bars from falling apart due to improper binding, thus avoiding operational hazards. It also prevents the steel bars from being too large to be secured by the fixing device, which would waste time and affect the work progress by requiring the selection of a new fixing device.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a lifting ring structure for hoisting a steel cage, comprising four inner ring fixing devices provided on the inner side of the steel body, an outer ring fixing device fitted to the outer end face of the inner ring fixing device, and the outer ring fixing device fixed to the outer side of the steel body, two threaded holes being provided on the front and rear sides of the inner ring fixing device, and one threaded hole being provided on the front and rear sides of the outer ring fixing device, a threaded rod being rotatably provided inside the threaded hole one, and the threaded rod also rotating inside the threaded hole two.

[0008] Preferably, the tail of the threaded rod is rotatably provided with a nut, the front end of the threaded rod is fixedly provided with a short column, and the right side of the outer ring fixing device is fixedly provided with a fixing body, and the fixing body is fixed to the outer side of the lower outer ring fixing device.

[0009] By adopting the above technical solution, the nut can be tightened and fixed.

[0010] Preferably, a cube is fixedly provided in the middle of the right end face of the fixing body, a threaded groove is provided in the middle of the cube, and a short threaded rod is rotatably provided in the middle of the threaded groove.

[0011] By adopting the above technical solution, the entire structure can be fixed.

[0012] Preferably, a column block is fixedly provided on the front end face of the short grooved rod, a fixing block is fixedly provided on the lower side of the cube, a lifting ring device is fixedly provided on the right end face of the fixing block, and a threaded groove is provided in the middle of the fixing block, and the short grooved rod rotates through the threaded groove.

[0013] By adopting the above technical solution, lifting can be carried out conveniently.

[0014] Preferably, a second cube is fixedly provided on the lower side of the fixing block, and a third threaded groove is provided in the middle of the second cube, and the third threaded groove is rotatably penetrated by a short threaded rod.

[0015] By adopting the above technical solution, threads can be tightened and fixed.

[0016] Preferably, a steel binding rope is fixedly provided around the outer side of the steel bar body, and there are several steel binding ropes.

[0017] By adopting the above technical solution, the whole thing can be bound together and not dispersed.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. This utility model utilizes an outer ring fixing device, an inner ring fixing device, and a threaded rod. These components allow for threaded tightening of the outer and inner ring fixing devices, preventing the scaffold from collapsing due to improperly tied reinforcing bars and posing a safety hazard. It also prevents situations where the fixing devices cannot secure excessively large reinforcing bars, necessitating the selection of new fixing devices and thus saving time and impacting work progress.

[0020] 2. This utility model uses a fixing block, a lifting ring device, and a short grooved rod to make it easier to carry out suspended work and to prevent items from falling and causing operational hazards due to improper fixing of the lifting ring. Attached Figure Description
