Description

Technical Field

[0001] The utility model relates to the technical field of sling, in particular to an endless sling with high breaking force. Background Technique

[0002] A sling is a flat belt used for hoisting goods, which has the characteristics of being light, soft, high-strength, corrosion-resistant, etc., and is suitable for various goods hoisting scenarios. Traditional slings mostly adopt fiber belts made of fiber materials. The fiber belts have good toughness, high strength, and corrosion resistance, and are widely used in many occasions.

[0003] However, fiber belts also have deficiencies. Especially, they are not resistant to shearing, are easily cut by hard objects, have low breaking force, and after being cut, the damaged part gradually expands, and finally the whole sling breaks.

[0004] Therefore, in view of the above problems, it is necessary for the applicant to design an endless sling with high breaking force to solve the problems. Summary of the Invention

[0005] The purpose of the utility model is to provide an endless sling with high breaking force to solve the problems mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: an endless sling with high breaking force, including an endless sling body, and a connecting rod is detachably installed on the inner side of the endless sling body. A connecting piece is detachably installed on the outer side of the connecting rod, and a hook is detachably installed on the inner side of the connecting piece;

[0007] The endless sling body includes a core layer, a tensile layer is arranged on the outer side of the core layer, and a wear-resistant protective layer woven by fiber yarns intersecting with each other vertically and horizontally is arranged on the outer side of the tensile layer.

[0008] Further, the core layer includes a plurality of metal wires arranged horizontally, a knitting sleeve is sleeved on the outer sides of the plurality of metal wires, and the knitting sleeve abuts against the tensile layer.

[0009] Through the above structural design, the knitting sleeve is convenient for shaping a plurality of metal wires. The metal wires have strong toughness, and are convenient for preventing the whole sling from breaking when part of the sling is cut, and the safety is high.

[0010] Further, the knitting sleeve includes a first knitting belt and a second knitting belt that intersects with the first knitting belt vertically and horizontally. The first knitting belt and the second knitting belt are woven by fiber yarns intersecting with each other vertically and horizontally.

[0011] Through the above structural design, the first knitting belt and the second knitting belt woven by the vertically and horizontally intersecting knitting method have strong tensile ability, which is convenient for improving the maximum load-bearing capacity of the sling, thereby improving the breaking force of the sling.

[0012] Further, the tensile layer includes a plurality of vertical elastic lines, elastic loops are provided at both ends of the plurality of vertical elastic lines, and horizontal elastic lines are arranged along the horizontal direction on the outer side of the elastic loops.

[0013] Through the above structural design, during use, when an external tensile force acts on the sling, the tensile force will pull the vertical elastic lines or the horizontal elastic lines. The vertical elastic lines or the horizontal elastic lines will pull the elastic loops, and the vertical elastic lines, the horizontal elastic lines and the elastic loops will deform to buffer the tensile force, preventing the sling from breaking, thereby improving the breaking force of the sling.

[0014] Further, both the vertical elastic lines and the horizontal elastic lines are spiral nylon bundles twisted together by nylon threads.

[0015] Through the above structural design, nylon threads have high tensile strength and can bear large tensile loads, facilitating the improvement of the breaking force of the sling.

[0016] Further, the elastic loop is made of an elastic material, preferably polyester fiber material.

[0017] Through the above structural design, the polyester fiber material has high strength and elastic recovery ability, making the fabric strong and durable, and at the same time can quickly return to its original state, facilitating the sling to return to its original state after the external tensile force disappears, thereby improving the service life of the sling.

[0018] Compared with the prior art, the beneficial effects of the present utility model are: the annular sling with high breaking force has a high maximum load-bearing capacity under the action of tensile force, and is not easy to break after being damaged, with high safety.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0027] As Figures 1-6 shown, a ring sling with high breaking force of the present utility model includes a ring sling body 1, and a connecting rod 2 is detachably installed on the inner side of the ring sling body 1. A connecting piece 3 is detachably installed on the outer side of the connecting rod 2, and a hook 4 is detachably installed on the inner side of the connecting piece 3. The ring sling body 1 includes a core layer 5, a tensile layer 6 is arranged on the outer side of the core layer 5, and a wear-resistant protective layer 7 woven by fiber yarns intersecting with each other vertically and horizontally is arranged on the outer side of the tensile layer 6.

[0028] The core layer 5 includes a plurality of metal wires 50 arranged horizontally. A braided sleeve 51 is sleeved on the outer side of the plurality of metal wires 50, and the braided sleeve 51 abuts against the tensile layer 6. The plurality of metal wires 50 can be shaped by the braided sleeve 51. The metal wires 50 have strong toughness, and are convenient for preventing the overall fracture of the sling in the case where part of the sling is cut, with high safety. The braided sleeve 51 includes a first braided belt 8 and a second braided belt 9 that intersects with the first braided belt 8 vertically and horizontally. The first braided belt 8 and the second braided belt 9 are woven by fiber yarns intersecting with each other vertically and horizontally. The tensile capacity of the first braided belt 8 and the second braided belt 9 woven by the vertically and horizontally intersecting weaving method is strong, which is convenient for improving the maximum load-bearing capacity of the sling, thereby improving the breaking force of the sling.

[0029] The tensile layer 6 includes a plurality of vertical elastic threads 10. Elastic loops 11 are provided at both ends of the plurality of vertical elastic threads 10. And horizontal elastic threads 12 are arranged along the horizontal direction on the outer side of the elastic loops 11. When in use, when an external tensile force acts on the sling, the tensile force will pull the vertical elastic threads 10 or the horizontal elastic threads 12. The vertical elastic threads 10 or the horizontal elastic threads 12 will pull the elastic loops 11. The vertical elastic threads 10, the horizontal elastic threads 12 and the elastic loops 11 will deform to buffer the tensile force, preventing the sling from breaking, thereby improving the breaking force of the sling. The vertical elastic threads 10 and the horizontal elastic threads 12 are both spiral nylon bundles twisted together by nylon threads. The nylon threads have a high tensile strength and can bear a large tensile load, which is convenient for improving the breaking force of the sling. The elastic loops 11 are made of polyester fiber material. The polyester fiber material has a very high strength and elastic recovery ability, making the fabric firm and durable, and at the same time can quickly return to its original state, which is convenient for the sling to return to its original state after the external tensile force disappears, thereby improving the service life of the sling.
