Technical Field
[0001] The utility model relates to the technical field of construction tools, in particular to a simple lifting sling for a steel bar truss floor slab. Background Art
[0002] During the construction of steel structure buildings, after the steel bar truss floor slabs are delivered to the site, they are usually packed and stacked in the construction site. During the existing lifting construction of steel bar truss floor slabs, lifting belts or steel wires are usually used for lifting the floor slabs. When using a lifting belt for lifting, the lifting belt contacts and rubs against the floor slab during lifting, which is likely to cause wear of the lifting belt and affect safety; when using a steel wire for lifting, the steel wire is relatively thin, and the floor slab is likely to be deformed and damaged during lifting.
[0003] Conventional lifting tools cannot well complete the lifting of the floor slab. Therefore, the proposed solution of this application is a simple lifting sling for a steel bar truss floor slab to solve the above problems. Content of the Utility Model
[0004] The purpose of the utility model is to provide a simple lifting sling for a steel bar truss floor slab, which solves the technical problems raised in the background art.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A simple lifting sling for a steel bar truss floor slab, including a first support rod and a second support rod. The right end of the first support rod is fixedly connected with a second sliding ring. The left end of the second support rod is fixedly connected with a first sliding ring. The first sliding ring is sleeved on the first support rod. The second sliding ring is sleeved on the second support rod. The left end of the first support rod and the right end of the second support rod are both fixedly connected with connecting plates. A connecting hole is opened on the connecting plate. A lifting ring is sleeved in the connecting hole. A side protection mechanism is arranged above the connecting plate.
[0006] Preferably, a limiting insertion hole is opened on the connecting plate. The side protection mechanism includes a limiting insertion rod. The lower end of the limiting insertion rod passes through the limiting insertion hole and extends to the lower side of the connecting plate. The upper end of the limiting insertion rod is fixedly connected with a baffle plate. The upper end of the baffle plate is fixedly connected with a protection support rod. The upper end of the protection support rod is fixedly connected with a limiting frame.
[0007] Preferably, a locking bolt is arranged on the front side of the first support rod. The rear end of the locking bolt penetrates through the first support rod and abuts against the outer side wall of the second support rod. The locking bolt is threadedly connected with the first support rod.
[0008] Preferably, the locking bolt is close to the second sliding ring.

Detailed implementation manners
[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0022] Please refer to Figures 1-6 , the present invention provides a technical solution: a simple lifting sling for a steel bar truss floor slab, including a first support rod 1 and a second support rod 2. A second sliding ring 4 is fixedly connected to the right end of the first support rod 1, and a first sliding ring 3 is fixedly connected to the left end of the second support rod 2. The first sliding ring 3 is sleeved on the first support rod 1, and the second sliding ring 4 is sleeved on the second support rod 2. Connecting plates 6 are fixedly connected to the left end of the first support rod 1 and the right end of the second support rod 2. Connecting holes 7 are formed in the connecting plates 6, and lifting rings 8 are sleeved in the connecting holes 7. A side protection mechanism is arranged above the connecting plates 6. During use, loosen the locking bolt 5, and by adjusting the positional relationship between the first support rod 1 and the second support rod 2, the distance between the connecting plates 6 on the left and right sides can be realized, and thus the lifting of steel bar truss floor slabs with different width dimensions can be realized, greatly improving the practicability of the device;
[0023] Limiting jacks 9 are formed in the connecting plates 6. The side protection mechanism includes limiting insertion rods 10. The lower end of the limiting insertion rod 10 passes through the limiting jack 9 and extends below the connecting plate 6. A baffle 11 is fixedly connected to the upper end of the limiting insertion rod 10, and a protective support rod 12 is fixedly connected to the upper end of the baffle 11. A limiting frame 13 is fixedly connected to the upper end of the protective support rod 12. The limiting frame 13 is of a U-shaped structure. During hoisting, the steel wire rope 15 is placed inside the limiting frame 13, and the steel wire rope 15 is blocked by the side protection mechanisms on the left and right sides to prevent the steel wire rope 15 from squeezing the side of the steel bar truss floor slab at the upper position, thereby avoiding deformation or damage of the steel bar truss floor slab during hoisting;
[0024] A locking bolt 5 is arranged on the front side of the first support rod 1. The rear end of the locking bolt 5 passes through the first support rod 1 and abuts against the outer wall of the second support rod 2. The locking bolt 5 is threadedly connected to the first support rod 1. The locking bolt 5 is close to the second sliding ring 4. After adjusting the distance between the connecting plates 6 on the left and right sides, the second support rod 2 is fixedly abutted by rotating the locking bolt 5, thereby preventing the first support rod 1 and the second support rod 2 from sliding, and thus ensuring the safety of hoisting.
[0025] Working principle: When in use, loosen the locking bolt 5. By adjusting the positional relationship between the first support rod 1 and the second support rod 2, the distance between the connecting plates 6 on the left and right sides can be achieved, and thus the hoisting of steel bar truss floor slabs with different width dimensions can be realized. Pass multiple hoisting riggings through the floor slab truss, and connect the lifting rings 8 on the left and right sides to the hook 14 in the hoisting equipment, thereby realizing the hoisting of the steel bar truss floor slab. At the same time, connect the side protection mechanism to the connecting plate 6 through the limit insertion rod 10 and the limit insertion hole 9. During hoisting, the steel wire rope 15 is placed inside the limit frame 13, and the side protection mechanisms on the left and right sides are used to block the steel wire rope 15 to prevent the steel wire rope 15 from squeezing the side of the steel bar truss floor slab at the upper position, thereby avoiding deformation or damage of the steel bar truss floor slab during hoisting.
