Technical Field

[0001] The embodiments disclosed herein relate to the field of rigging technology, and more specifically, to a sling-type flat sling. Background Technology

[0002] In various lifting operations, the performance of slings is crucial. Traditional strap-type flat slings have significant shortcomings in practical applications. Most previous strap-type flat slings only offered a single vertical lifting method, severely limiting their flexibility when facing complex lifting environments and oddly shaped goods. For example, when working in confined spaces or lifting irregularly shaped or offset goods, a single lifting method is insufficient for precise positioning and stable lifting, requiring multiple adjustments to the sling position. This not only wastes time but also increases safety risks. Furthermore, existing strap-type flat slings lack sufficient adaptability when used with different lifting equipment.

[0003] Therefore, improvements have been made to address the aforementioned issues. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a back strap flat sling, which solves the technical problem that the existing slings have a single usage mode and cannot be adapted to various shaped goods.

[0005] According to one aspect, at least one embodiment of this disclosure provides a sling-type flat sling, comprising:

[0006] The main frame and the hook, wherein the hook is rotatably connected within the main frame;

[0007] A pair of slings and a connecting assembly, wherein the slings are disposed on the main frame and the connecting assembly is disposed between the slings and the main frame;

[0008] Hook assembly, the hook assembly being disposed on the sling;

[0009] The connecting component includes a pair of notches, which are formed at both ends of the main frame. A connector is rotatably connected to the notch via a pin.

[0034] like Figures 1-5 As shown, it illustrates a sling-type flat sling according to an embodiment of the present disclosure, comprising:

[0035] The main frame 1 and the hook 2 are rotatably connected inside the main frame 1;

[0036] A pair of lifting straps 3 and a connecting component 4, wherein the lifting straps 3 are mounted on the main frame 1 and the connecting component 4 is mounted between the lifting straps 3 and the main frame 1;

[0037] Hook assembly 5 is mounted on sling 3;

[0038] The connecting component 4 includes a pair of notches 4-1, which are opened at both ends of the main frame 1. A connector 4-2 is rotatably connected to the notch 4-1 by a pin. The surface of the connector 4-2 is provided with a mounting groove 4-3. The upper end of the sling 3 is inserted into the mounting groove 4-3. Both ends of the mounting groove 4-3 are provided with a first threaded groove 4-4. A pressure plate 4-5 is inserted into the mounting groove 4-3. Both ends of the surface of the pressure plate 4-5 are inserted with bolts 4-6. The bolts 4-6 are screwed into the first threaded groove 4-4.

[0039] In some examples, to achieve a secure connection between the sling 3 and the main frame 1, a connecting component 4 is designed. This component includes a pair of notches 4-1, which are respectively opened at both ends of the main frame 1. A swingable connector 4-2 is rotatably connected to the notch 4-1 via a pin. The connector 4-2 is the basic structure for connecting the sling 3. The surface of the connector 4-2 is provided with a mounting groove 4-3, which is a concave structure for inserting the sling 3. The mounting groove 4-3 has a first threaded groove 4-4 at both ends, which cooperates with the pressure plate 4-5 inserted into the mounting groove 4-3. Bolts 4-6 are inserted into both ends of the surface of the pressure plate 4-5 and screwed into the first threaded groove 4-4. When the bolts 4-6 are tightened, the pressure plate 4-5 will tightly press the upper end of the sling 3 into the mounting groove 4-3, thereby achieving a secure connection between the sling 3 and the connector 4-2, and making the sling 3...

[0040] like Figures 1-5 As shown, this embodiment proposes a hook assembly 5 including a pair of hooks 5-1, each hook 5-1 being fixed to the lower end of a sling 3. A first frame 5-2 and a second frame 5-3 are respectively fitted onto the pair of slings 3. Both the first frame 5-2 and the second frame 5-3 have a pair of protrusions 5-4 on their surfaces. The protrusions 5-4 on the surface of the first frame 5-2 have mating grooves 5-5, and the protrusions 5-4 on the surface of the second frame 5-3 have mating blocks 5-6. Both the first sleeve 5-2 and the second sleeve 5-3 have protrusions 5-7 on their surfaces. The inner surfaces of the first sleeve 5-2 and the second sleeve 5-3 are provided with second threaded grooves 5-8 between the protrusions 5-7 and the inner surfaces of the first sleeve 5-2 and the second sleeve 5-3. Both the side surfaces of the first sleeve 5-2 and the second sleeve 5-3 are provided with circular grooves 5-9. The surface of the sling 3 is provided with several through holes 5-10. A clamping frame 5-11 is inserted into the circular grooves 5-9 and the through holes 5-10. One end of the clamping frame 5-11 is screwed into the second threaded groove 5-8.

[0041] In some examples, to achieve a reliable hook connection and flexible adjustment, a hook assembly 5 is designed. This assembly includes a pair of hooks 5-1, which are fixed to the bottom of two slings 3 respectively. These hooks are mainly used to hook the object being lifted, thus achieving the lifting function. A first frame 5-2 and a second frame 5-3 are respectively fitted onto the pair of slings 3. The first frame 5-2 and the second frame 5-3 can be moved and adjusted on the slings 3. Each of the first frame 5-2 and the second frame 5-3 has a pair of protrusions 5-4 on its surface. The protrusions 5-4 on the surface of the first frame 5-2 have mating grooves 5-5, and the protrusions 5-4 on the surface of the second frame 5-3 have mating blocks 5-6. The mating blocks 5-6 can be inserted into the mating grooves 5-5, allowing the first frame 5-2 and the second frame 5-3 to be accurately connected together, making the two slings 3 form a complete hook connection. The system is integrated to ensure the strength and stability of the connection and lifting. Both the first frame 5-2 and the second frame 5-3 have protrusions 5-7 on their surfaces, and a second threaded groove 5-8 is formed between the inner surface and the protrusion 5-7. Circular grooves 5-9 on the side surfaces of the first frame 5-2 and the second frame 5-3 correspond to several through holes 5-10 on the surface of the sling 3. When the clamping frame 5-11 is inserted into the circular grooves 5-9 and through holes 5-10 and screwed into the second threaded groove 5-8, the first frame 5-2 and the second frame 5-3 can be firmly fixed to the sling 3. Furthermore, the position of the first frame 5-2 and the second frame 5-3 on the sling 3 can be adjusted by selecting different through holes 5-10 according to actual needs, thereby adjusting the length and position of the hook to adapt to the lifting requirements of different objects.

[0042] For example, such as Figure 2 as well as Figure 5 As shown, the surface of the clamping frame 5-11 is provided with a screwing groove 6, which has a polygonal structure.

[0043] In some examples, the concave screwing method makes the surface smoother and less protruding, preventing wear and tear on goods.

[0044] For example, such as Figure 4 As shown, the inner surface of the pressure plate 4-5 is provided with a toothed layer 7.

[0045] In some examples, the gripping force of the pressure plate 4-5 on the sling 3 is increased by the toothed layer 7, thereby improving the clamping effect.

[0046] For example, such as Figure 1 As shown, boss 5-7 is located at the interval between bosses 5-4.

[0047] In some examples, the spacing facilitates the staggered splicing positions of the first frame 5-2 and the second frame 5-3, avoiding obstruction.

[0048] In actual use: Insert the upper end of the sling 3 into the mounting groove 4-3 of the connector 4-2, tighten the pressure plate 4-5 with bolts 4-6, adjust the length and position of the sling 3 according to the shape of the goods and the lifting environment, move the first set of frames 5-2 and the second set of frames 5-3 to the appropriate position on the sling 3, insert the clamping frame 5-11 and tighten it, hang the hook 2 on the lifting equipment, hook the goods with the hook 5-1, and operate the lifting equipment to lift and transport the goods. Alternatively, connect the first set of frames 5-2 and the second set of frames 5-3 of the two slings 3, insert the docking block 5-6 into the docking groove 5-5, and then lift the goods.
