A multi-row lifting rope sling

Abstract

This utility model discloses a multi-row lifting sling, belonging to the field of lifting sling technology. It includes a main outer sheath, with a storage component slidably connected to the center of the outer surface of the main outer sheath, and a sling body component fixedly connected inside the main outer sheath. Through the storage component, the straight sling between the first and second anti-rotation plates is stretched outwards, and then the two are connected using threaded bolts and fastening nuts. This allows for overlapping storage of the straight slings, reducing the extended length and preventing clutter. The movable arrangement between the first and second anti-rotation plates prevents excessive compression of the straight slings, thus avoiding material fatigue or damage and reduced strength. The sling body component enhances the waterproof performance of the waterproof layer, reducing corrosion caused by moisture and ensuring its strength. Furthermore, the addition of a metal main rope to the inner core strengthens its lifting strength and increases its load-bearing capacity.

Description

Technical Field

[0001] This utility model relates to the field of lifting sling technology, specifically a multi-row lifting rope sling. Background Technology

[0002] Lifting slings are safety devices used for lifting and moving heavy objects. They are typically made of high-strength synthetic fiber materials and can be designed in loops or flat shapes. They are equipped with hooks or other connecting devices, allowing them to be safely attached to lifting equipment such as cranes and forklifts. Lifting slings have good abrasion resistance and tensile strength, effectively distributing the load and reducing the tilting and swaying of heavy objects during lifting, ensuring the safety and stability of the handling process. Lifting slings have a wide range of applications, covering multiple industries such as construction, logistics, manufacturing, and transportation.

[0003] Existing lifting slings often need to be suspended during storage to avoid contact with the ground or other objects, reduce friction and wear, and keep them dry and clean. However, when the lifting sling is too long, it is difficult to suspend it completely, which can lead to excessive dragging of the sling and resulting in cluttered storage space.

[0004] Therefore, this utility model provides a multi-row lifting rope sling to solve the above problems. Utility Model Content

[0010] As a preferred technical solution of this application, a second anti-rotation plate is slidably connected to both sides of the outer surface of the main outer protective layer, and a through groove for threaded bolts to pass through is provided at the corner of the upper surface of the second anti-rotation plate.

[0011] As a preferred technical solution of this application, the belt assembly includes a straight belt, the outer surface of which is fixedly connected to the interior of the main outer protective layer, the outer surface of which is provided with a waterproof layer, and the interior of which is provided with a main rope.

[0012] As a preferred technical solution of this application, both ends of the straight belt are fixedly connected to connectors, and the outer surface of the connectors is fixedly connected to a secondary outer protective layer.

[0013] As a preferred technical solution of this application, both the straight band and the connector include warp, weft and connecting line, the warp and weft are interwoven, and the connecting line is interwoven again at the intersection of the warp and weft.

[0014] As a preferred technical solution of this application, the main rope is made of metal and the straight belt is made of polyester fiber.

[0015] (III) Beneficial Effects

[0016] 1. By using the storage components, the straight strip between the first anti-rotation plate and the second anti-rotation plate is stretched outward, and then the two are connected with threaded bolts and fastening nuts. This allows the straight strip to be stored in an overlapping manner, reducing the length of the extended straight strip and avoiding clutter in the storage space. Furthermore, the first anti-rotation plate and the second anti-rotation plate are movable, which can prevent excessive compression of the straight strip, which could lead to material fatigue or damage and reduce its strength.

[0017] 2. By setting up the belt components, the waterproof layer improves its waterproof performance, reduces the corrosion caused by moisture, and ensures its strength. In addition, the addition of a metal main rope to the inner core can enhance its lifting strength and increase its load-bearing capacity. Attached Figure Description

[0025] 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.

[0026] This utility model provides a multi-row lifting rope sling, such as Figures 1-5 As shown, a multi-row lifting rope sling includes a main outer sheath 1, a storage component is slidably connected to the middle of the outer surface of the main outer sheath 1, and a sling body component is fixedly connected to the inside of the main outer sheath 1.

[0027] The storage component includes a first anti-rotation plate 2, which is internally slidably connected to the inside of the main outer protective layer 1. Threaded bolts 3 are fixedly connected to the upper and lower corners of the first anti-rotation plate 2. Fastening nuts 4 are threaded onto the outer surface of the threaded bolts 3. The straight band 6 between the first anti-rotation plate 2 and the second anti-rotation plate 5 is stretched outwards, and then the two are connected using threaded bolts 3 and fastening nuts 4. This allows the straight band 6 to be stored in an overlapping manner, reducing the length of the extended straight band 6 and avoiding clutter in the storage space. Furthermore, the first anti-rotation plate 2 and the second anti-rotation plate 5 are movable, which can prevent excessive compression of the straight band 6, thus avoiding material fatigue or damage and reducing its strength.

[0028] The outer surfaces of the main outer protective layer 1 are slidably connected with the second anti-rotation plate 5. The corners of the upper surface of the second anti-rotation plate 5 are provided with through grooves through which the threaded bolt 3 can pass.

[0029] The belt assembly includes a straight belt 6, the outer surface of which is fixedly connected to the interior of the main outer protective layer 1. A waterproof layer 7 is provided on the outer surface of the straight belt 6, and a main rope 8 is provided inside the straight belt 6. The main rope 8 is made of metal, while the straight belt 6 is made of polyester fiber. Polyester fiber has high strength, lightness, flexibility, corrosion resistance, low elongation, and good UV resistance. The waterproof layer 7 can improve its waterproof performance, reduce the corrosion caused by moisture, and ensure its strength. In addition, the addition of the metal main rope 8 to the inner core can enhance its lifting strength and increase its load-bearing capacity.

[0030] Both ends of the straight belt 6 are fixedly connected to connectors 9. The outer surface of the connectors 9 is fixedly connected to a secondary outer protective layer 10. The connectors 9 facilitate connection with the crane and the object being lifted, and the secondary outer protective layer 10 can improve its wear resistance.

[0031] Both the straight belt 6 and the connector 9 include warp 11, weft 12 and connecting line 13. The warp 11 and weft 12 are interwoven, and the connecting line 13 is interwoven again at the intersection of the warp 11 and weft 12. The additional connecting line 13 weaves the interwoven points again, which can strengthen the weaving density and firmness, thereby improving the overall strength.
