Description

Technical Field

[0001] This utility model relates to the field of lifting sling technology, specifically a woven sling for lifting. Background Technology

[0002] Lifting equipment is typically used in the manufacturing of machinery and the handling of objects. As the requirements for the surface quality of the objects being lifted continue to increase, traditional lifting equipment such as wire ropes and chains can no longer meet the requirements. Therefore, they have been gradually replaced by lifting slings, which are soft, have smooth surfaces, and are less likely to damage the surface of the objects being lifted.

[0003] Currently, lifting slings typically consist of a flat sling with lifting rings at both ends. When not in use, the sling needs to be rolled up for easy storage. However, when rolling up longer slings, the lack of a reel results in insufficient support and anchor points, making winding difficult, prone to deviation and unevenness, and leading to low winding efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a woven belt for hoisting in order to solve the above-mentioned problems.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a woven belt for lifting, comprising a belt body, lifting rings at both ends of the belt body, a connecting sleeve at the middle position of the belt body, the connecting sleeve comprising a hollow section and a connecting section, an intermediate section between the hollow section and the connecting section, the connecting section being adhered to the belt body, and a spool being provided inside the hollow section, the spool being extendable or retractable.

[0006] As a further feature of this invention, the reel includes a cylinder fixedly connected inside the hollow section, and a connecting rod is provided inside the cylinder, which can extend or retract inside the cylinder.

[0007] As a further feature of this invention, the connecting rod is provided with a grip handle, which is cross-shaped.

[0008] As a further feature of this invention, a limiting strip is connected to the end of the connecting rod away from the handle. An annular groove is provided circumferentially on the inner wall of the cylinder. Two sliding grooves communicating with the annular groove are provided vertically on the inner wall of the cylinder. The two ends of the limiting strip are slidably connected inside the sliding grooves and are used to be engaged inside the annular grooves.

[0009] As a further feature of this invention, both the belt body and the hanging ring are woven from several braided yarns. The braided yarns include a core and an outer wrapping yarn spirally wound around the outside of the core. The outer wrapping yarn is made of several twisted nylon fibers.

[0010] As a further feature of this invention, the core is made of several twisted polyester fibers.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] When this utility model needs to be wound up, the reel can be stretched first to make it easy to hold, and then the reel can be twisted while holding it. With the reel as the center, the middle section can be pulled by the connecting section to make the belt spirally wound on the reel until it is rolled up. Then the reel can be shortened and reset, thus realizing the winding of the hoisting woven belt. The reel is supported and fixed by the support points, making the winding operation more convenient and ensuring neat winding with high winding efficiency. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1 , Figure 2 , Figure 4As shown, a lifting braided sling includes a sling body 1 and lifting rings 2 at both ends of the sling body 1. Both the sling body 1 and the lifting rings 2 are woven from several braided yarns. The braided yarns include a core yarn 12 and an outer covering yarn 13 spirally wound around the outside of the core yarn 12. The outer covering yarn 13 is made of several twisted nylon fibers, which have high abrasion resistance, thus ensuring the abrasion resistance of the sling body 1 and the lifting rings 2, making the lifting braided sling durable. The core yarn 12 is made of several twisted polyester fibers, which have high strength and high toughness, thus ensuring the tensile strength of the lifting braided sling. A connecting sleeve is provided in the middle of the sling body 1. The connecting sleeve includes a middle... The system includes a hollow section 3 and a connecting section 4, with an intermediate section 5 between them. The connecting section 4 is bonded to the belt body 1, and a reel is located inside the hollow section 3. The reel can be extended or shortened. When it is necessary to reel in the hoisting woven belt, the reel can be extended first to make it easy to hold. Then, the reel can be held and twisted. With the reel as the center, the intermediate section 5 can be pulled by the connecting section 4, causing the belt body 1 to spirally wind onto the reel until it is rolled up. Then, the reel can be shortened and reset, thus achieving the reeling of the hoisting woven belt. The reel is supported and fixed at the support points, making the reeling operation convenient and ensuring neat reeling with high efficiency.

[0020] Please see Figure 1-3 As shown, the reel includes a cylinder 6 fixedly connected inside the hollow section 3, and a connecting rod 7 is provided inside the cylinder 6. The connecting rod 7 can extend or retract inside the cylinder 6. By pulling the connecting rod 7 out of the cylinder 6, the reel can be extended; by pushing the connecting rod 7 into the cylinder 6, the reel can be shortened. The operation is relatively convenient and simple. A grip handle 8 is provided on the connecting rod 7, and the grip handle 8 is cross-shaped. When it is necessary to twist the reel, the grip handle 8 can be held to apply force. The grip handle 8 provides a force point for twisting the reel, making the operation easier and less strenuous. A limit strip 9 is connected to the end of the connecting rod 7 away from the grip handle 8. An annular groove 10 is circumferentially opened on the inner side wall of the cylinder 6, and two vertical grooves are opened on the inner side wall of the cylinder 6 that connect to the annular groove 10. The two ends of the limiting strip 9 are slidably connected inside the sliding groove 11 and used to engage inside the annular groove 10. When the connecting rod 7 is retracted into the cylinder 6, the two ends of the limiting strip 9 can be pushed to the connection between the sliding groove 11 and the annular groove 10. Then, the connecting rod 7 is rotated, causing the limiting strip 9 to rotate as well, so that the two ends of the limiting strip 9 are engaged inside the annular groove 10. The limiting strip 9 can be locked by the limiting of the annular groove 10, thereby fixing the connecting rod 7 inside the cylinder 6, keeping the reel in a shortened state, and avoiding affecting the normal use of the hoisting braided belt. When rewinding, the connecting rod 7 can be rotated, so that the two ends of the limiting strip 9 slide from the annular groove 10 to the sliding groove 11. The connecting rod 7 can then slide up and down through the sliding groove 11, making it easy to pull the connecting rod 7 out of the cylinder 6.
