Technical Field

[0001] The utility model relates to the technical field of steel lifting tools, and particularly relates to a steel lifting tool. Background Art

[0002] In the field of hoisting and lifting, with the increasing strictness of industry specifications and the popularization and application of lifting technologies, numerous types of steel lifting tools have emerged on the market. Common lifting tools include L-shaped lifting tools, horizontal hooks, flipping hooks, vertical hooks, etc. When hoisting and transporting steel, steel lifting tools are usually used to fix the steel; when hoisting and transporting steel, various hoisting methods can be adopted, such as single-point hoisting, double-point hoisting, and multi-point hoisting, and the lifting tools can adopt various special rigging such as hooks, steel wires, and chains.

[0003] In the operation of steel plate hoisting, when dealing with the problem of cross-hoisting of steel such as steel plates and profiled steel, the limited applicability of traditional lifting tools leads to the need for operators to frequently replace the hooks, which not only reduces the operation efficiency but also may result in hoisting behaviors that do not conform to safety specifications; for the hoisting of profiled steel, due to the lack of special conversion lifting tools, construction parties usually have to adopt destructive methods to the steel structure to complete the hoisting task, such as cutting hoisting holes, etc. These methods not only damage the structural integrity of the profiled steel but also increase the construction cost and potential safety risks.

[0004] Existing lifting tools are difficult to meet the cross-hoisting requirements of steel plates and profiled steel, and a new steel lifting tool solution needs to be provided. Summary of the Utility Model

Detailed implementation manners

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

[0024] The following description provides examples and does not limit the scope, applicability or examples set forth in the claims.

[0025] Embodiment 1:

[0026] Please refer to Figure 1 , Figure 1 which shows a schematic diagram of the structure of a steel sling provided by the embodiment of the present application. As Figure 1 shown, a steel sling includes an anti-slip limiting member 1 and a movable extrusion member 2, and the movable extrusion member 2 is rotatably arranged on the anti-slip limiting member 1; a first anti-slip structure 1-1 is formed on one side surface of the anti-slip limiting member 1, and a second anti-slip structure 2-1 is formed at one end of the movable extrusion member 2, and the first anti-slip structure 1-1 and the second anti-slip structure 2-1 are arranged opposite to each other.

[0027] Specifically, the first anti-skid structure 1-1 is located at one end of the anti-skid stopper 1 that matches the steel plate 20, and the second anti-skid structure 2-1 is located at one end of the movable extrusion member 2 that matches the steel plate or steel section; one side of the steel plate 20 contacts the first anti-skid structure 1-1 on the anti-skid stopper 1, and the other side of the steel plate 20 contacts the second anti-skid structure 2-1 on the movable extrusion member 2; when hoisting the steel plate 20, the movable extrusion clamp member 2 rotates relative to the anti-skid stopper 1 under the drive of an external force to squeeze the steel plate 20 between the anti-skid stopper 1 and the movable extrusion clamp member 2, thereby increasing the friction between the first anti-skid structure 1-1 and the second anti-skid structure 2-1 and the steel plate 20, and preventing the steel plate 20 from slipping off the hoist during the hoisting process. At the same time, the movable extrusion member 2 is rotatably arranged on the anti-skid stopper 1, so that the distance between the end of the movable extrusion member 2 and the surface of the anti-skid stopper 1 can be adjusted to meet the hoisting requirements of steel plates 20 of different thicknesses.

[0028] For further information, see Figure 4 When the steel hanger 10 hoists the steel plate 20, steel hangers 10 are provided at both ends of the steel plate 20. The anti-slip limiter 1 and the movable extrusion member 2 clamp the steel plate 20 between the steel hangers 10. The first anti-slip structure 1-1 cooperates with the second anti-slip structure 2-1 to increase the friction between the steel plate 20 and prevent the steel plate 20 from falling off.

[0029] See also Figure 1 and Figure 2 The anti-skid limiter 1 is in a U-shaped structure, including a hoisting load-bearing plate 1-3, an arc-shaped connecting plate 1-4 and an anti-skid plate 1-5; a first limiting groove 1-31 is formed on the hoisting load-bearing plate 1-3, and a movable extrusion member 2 is arranged in the first limiting groove 1-31. At the same time, a first bearing pin 1-2 is arranged on the anti-skid limiter 1, and the first bearing pin 1-2 is located on the hoisting load-bearing plate 1-3. The movable extrusion member 2 is rotatably connected to the first bearing pin 1-2. The anti-skid limiter 1 limits the movable range of the movable extrusion member 2 through the first bearing pin 1-2 and the first limiting groove 1-31.

[0030] Specifically, the lifting load-bearing plate 1-3 and the anti-slip plate 1-5 are respectively connected to the two ends of the arc-shaped connecting plate 1-4, and are located on the same side of the arc-shaped connecting plate 1-4. The lifting load-bearing plate 1-3, the arc-shaped connecting plate 1-4 and the anti-slip plate 1-5 are fixedly connected and formed as one piece.

[0031] Furthermore, the first anti-skid structure 1-1 is arranged on the anti-skid plate 1-5, and the first anti-skid structure 1-1 is arranged close to one end of the lifting load-bearing plate 1-3; located on a side surface of the anti-skid plate 1-5 adjacent to the lifting load-bearing plate 1-3, the first anti-skid structure 1-1 contacts one side surface of the steel plate 20.

[0032] See also Figure 3, the movable pressing member 2 includes a hanging plate 2-2 and two side plates 2-3. The two side plates 2-3 are arranged in parallel, increasing the contact area between the lifting tool and the steel plate 20 and improving the stability during the lifting operation; the hanging plate 2-2 is arranged between the two side plates 2-3; the second anti-slip structure 2-1 is arranged on the side plate 2-3 at one end away from the hanging plate 2-2. The second anti-slip structure 2-1 is adjacent to the first anti-slip structure 1-1 arranged on the anti-slip plate 1-5, and the second anti-slip structure 2-1 is in contact with the other side of the steel plate 20.

[0033] Please refer to Figure 3 , a second load-bearing pin shaft 2-4 is arranged between the hanging plate 2-2 and the two side plates 2-3. The two ends of the second load-bearing pin shaft 2-4 are respectively connected to the two side plates 2-3, and one end of the hanging plate 2-2 is rotatably connected to the second load-bearing pin shaft 2-4.

[0034] Please refer to Figure 3 , a lifting through hole 2-21 is formed at one end of the hanging plate 2-2 away from the side plate 2-3. The lifting through hole 2-21 is matched with the lifting equipment, facilitating the fixing of the lifting tool by the lifting equipment.

[0035] As an option of the embodiment of the present application, both the first anti-slip structure 1-1 and the second anti-slip structure 2-1 are serrated structures.

[0036] Embodiment Two:

[0037] Please refer to Figure 2 and Figure 5 , the difference feature between Embodiment Two and Embodiment One is that a second limiting groove 1-51 is formed on the anti-slip plate 1-5. The second limiting groove 1-51 is arranged along the length direction of the anti-slip plate 1-5. When lifting the H-shaped steel 30, the end of the H-shaped steel 30 is clamped on the anti-slip limiting member 1 through the second limiting groove 1-51 on the anti-slip plate 1-5, avoiding interference when the steel lifting tool 10 fixes the H-shaped steel 30.
