Description

Technical Field

[0001] The utility model relates to the technical field of slings, in particular to a steel structure sling which is easy to assemble. Background Art

[0002] In the metallurgical mining industry, there are three common lifting methods for steel structures. One is to use wire ropes or chains for binding and lifting, another is to use lifting ears for lifting, and the other is to use brackets for lifting.

[0003] For example, publication number CN116902739A is an assembled steel structure hoist. This invention uses a hanging plate in conjunction with a bracket to accommodate the steel structure for hoisting. During installation, the bracket is rotated, the T-block is inserted into the T-slot, and the buckle plate is rotated to snap into the fixing plate. Then, the bolt is rotated to fix the fixing plate to block the column T-slot, thereby forming a frame. It is used in conjunction with a hook for hoisting, making assembly more convenient and efficient, and no additional welding is required.

[0004] When assembling the steel structure hoist with the above solution, it is necessary to first use a crane to lift the top plate to the top of the bottom, and then rotate the brackets around the bottom so that the T-block at one end of the bracket is inserted into the T-slot at the top, and then rotate the buckle plate to engage with the fixing plate to limit the T-block and complete the assembly of the hoist. However, this installation method requires the assistance of a crane, and it is necessary to rotate multiple sets of limiting mechanisms separately to fix the bracket and the upper plate. This installation method is relatively cumbersome and inconvenient for assembling the hoist. Utility Model Content

[0005] The purpose of the utility model is to provide a steel structure sling that is easy to assemble, so as to solve the problem that the existing slings proposed in the above background technology are inconvenient to assemble.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: a steel structure hanger that is easy to assemble, comprising: a bottom plate and a pressure block, the outer side of the bottom plate is movably connected to a bracket via a rotating shaft, and one end of the bracket is plugged with a top plate,

[0007] The top of the base plate is fixedly connected to a hanging ring, and both sides of the top plate are movably connected to protective frames through rotating shafts. The top of the protective frame is fixedly connected to a connecting block, and one end of the bracket close to the base plate is fixedly connected to a magnet. The top of the top plate is threadedly connected to a threaded rod a, and the bottom of the threaded rod a is fixedly connected to a pressure block. A limiting mechanism for fixing the bracket is provided inside the base plate.

[0008] Preferably, the limiting mechanism includes a threaded rod b movably connected to the top plate through a bearing, and the outer side of the threaded rod b is threadedly connected to a threaded block.

[0009] Preferably, both sides of the threaded block are movably connected to connecting rods a via a rotating shaft, and one end of the connecting rod a is movably connected to a limiting rod via a rotating shaft.

[0010] Preferably, both sides of the limiting rod are movably connected to connecting rods b via a rotating shaft, and one end of the connecting rod b is movably connected to a clamping rod via a rotating shaft.

[0011] Preferably, one end of the clamping rod is engaged with the bracket, and the outer side of the limiting rod is slidably connected to the top plate.

[0012] Preferably, one end of the limiting rod is connected to the connecting block, and one end of the bracket is provided with a limiting groove matching the connecting block.

[0013] Compared with the prior art, the advantageous effects of the steel structure sling which is easy to assemble are as follows: during assembly, the brackets around the bottom plate are rotated and expanded, and the four groups of slots at the bottom of the top plate are docked with the brackets. After docking is completed, the threaded rod b in the limit mechanism can be rotated to perform threaded transmission with the threaded block, driving the two groups of connecting rods a to rotate. When the connecting rod a rotates, it can push the limit rod at one end to move, so that the limit rod enters the connecting block at the top of the protective frame. At this time, the protective frame will not be able to rotate, and the steel structure on the bottom plate will be limited. At the same time, the limit rod will also drive the two groups of connecting rods b to rotate and expand when moving, and push the clamping rod at one end to move, so that the four groups of clamping rods enter the brackets and complete the engagement with the brackets. In this way, through the above operation, multiple groups of clamping structures can be driven to move at the same time, so that the sling is assembled and both sides of the sling can be protected at the same time.

[0021] See also Figure 1-Figure 5 The utility model provides a technical solution: a steel structure sling that is easy to assemble, comprising: a bottom plate 1 and a pressure block 9, the outer side of the bottom plate 1 is movably connected to a bracket 2 through a rotating shaft, and one end of the bracket 2 is plugged with a top plate 3,

[0022] The top of the bottom plate 1 is fixedly connected to a lifting ring 4, and both sides of the top plate 3 are movably connected to protective frames 5 through rotating shafts. The top of the protective frame 5 is fixedly connected to a connecting block 6, and the end of the bracket 2 close to the bottom plate 1 is fixedly connected to a magnet 7. The top of the top plate 3 is threadedly connected to a threaded rod a8, and the bottom of the threaded rod a8 is fixedly connected to a pressure block 9. A limiting mechanism 10 for fixing the bracket 2 is provided inside the bottom plate 1. A slot matching the bracket 2 is provided at the bottom of the top plate 3. The bracket 2 and the top plate 3 form a sliding structure, and the protective frame 5 forms a rotating structure with the top plate 3 through the rotating shaft;

[0023] The limiting mechanism 10 includes a threaded rod b101 movably connected to the top plate 3 through a bearing, and the outer side of the threaded rod b101 is threadedly connected to a threaded block 102; both sides of the threaded block 102 are movably connected to a connecting rod a103 through a rotating shaft, and one end of the connecting rod a103 is movably connected to a limiting rod 104 through a rotating shaft; both sides of the limiting rod 104 are movably connected to a connecting rod b105 through a rotating shaft, and one end of the connecting rod b105 is movably connected to a clamping rod 106 through a rotating shaft; one end of the clamping rod 106 is engaged with the bracket 2, and the outer side of the limiting rod 104 is slidably connected to the top plate 3; one end of the limiting rod 104 is connected through the connecting block 6, and one end of the bracket 2 is provided with a limiting groove matching the connecting block 6, and the top of the connecting block 6 is provided with a through groove matching the limiting rod 104, the limiting rod 104 and the top plate 3 constitute a sliding structure, and the limiting rod 104 constitutes a rotating structure with the connecting rod b105 through the rotating shaft.

[0024] When the support frame 2 is lifted up, the four groups of slots at the bottom of the top plate 3 can be docked with the support frame 2. When the top plate 3 is lifted up, the protective frames 5 on both sides can be rotated under the action of gravity to block and protect the two sides of the bottom plate 1. After the docking is completed, the threaded rod b101 in the limiting mechanism 10 can be rotated to make the threaded rod b101 and the threaded block 102 perform threaded transmission. The threaded block 102 will move downward and drive the two groups of connecting rods a103 to rotate. When the connecting rod a103 rotates, it can push the limiting rod 104 at one end to move, so that the limiting rod 104 enters the connecting block 6 at the top of the protective frame 5. At this time, the protective frame 5 will not be able to rotate, thereby limiting the steel structure on the bottom plate 1.

[0025] At the same time, when the limit rod 104 moves, it will also drive the two groups of connecting rods b105 to rotate and expand, and push the clamping rod 106 at one end to move, so that the four groups of clamping rods 106 enter the bracket 2 and complete the engagement with the bracket 2.
