Detailed Implementation

[0024] 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.

[0025] Please see Figures 1 to 7 This utility model provides a technical solution: a tensile-resistant fiber suspension sling, comprising a fiber suspension sling body 100, the fiber suspension sling body 100 including a lifting ring 103, two hanging rings 102 fixed to the outer surface of the lifting ring 103, a main fiber rope 101 fixed to the bottom end of the hanging ring 102, a hook 104 fixed to the bottom end of the main fiber rope 101, and an anti-disengagement buckle plate 105 elastically connected to a torsion spring via a pivot on the inner side of the hook 104. The fiber suspension sling body 100 is also provided with:

[0026] An auxiliary tensile mechanism is provided, which includes a fixed mounting component disposed at the ends of the hanging ring 102 and the hook 104. An auxiliary tensile component is disposed at the end connection of the two fixed mounting components, and a rotating fixing component is disposed at the end connection of the auxiliary tensile component and the fixed mounting component. When the fiber hanging sling body 100 is subjected to force after installation, the auxiliary tensile mechanism provides auxiliary tensile protection for the main fiber rope 101, which is less likely to cause deformation and damage when subjected to large forces, thus extending its service life.

[0027] In order to facilitate the fixed installation of the tensile steel wire rope 1012 by means of a fixed installation component, in this embodiment, preferably, the fixed installation component includes a fixing ring 1011 welded and fixed to the outer surface of the end of the hanging ring 102 and the hook 104. The surface of the fixing ring 1011 is provided with mounting cylinders 1013 at equal intervals, so that the tensile steel wire rope 1012 can be closed and fixedly installed inside the mounting cylinders 1013 after the fixing ring 1011 is fixed.

[0028] In order to facilitate the tensile protection of the fixing ring 1011 by means of the auxiliary tensile component and to prevent deformation under stress, in this embodiment, preferably, the auxiliary tensile component includes four tensile steel wire ropes 1012 disposed on the outer surface of the main fiber rope 101. The ends of the tensile steel wire ropes 1012 are fixed with end caps 1014, and the ends of the end caps 1014 are embedded in the interior of the mounting cylinder 1013. After the four tensile steel wire ropes 1012 are installed, they can provide auxiliary tensile protection for the main fiber rope 101 and prevent deformation and damage under stress.

[0029] In order to facilitate the fixed installation of the end of the tensile steel wire rope 1012 by rotating the fixing assembly, in this embodiment, preferably, the rotating fixing assembly includes a fixing bolt 1015 threaded to the outer surface of the mounting cylinder 1013, and the surface of the end 1014 is provided with an internal thread hole 1016 that matches the fixing bolt 1015. The end of the end 1014 can be inserted into the inside of the mounting cylinder 1013, and the rotating fixing bolt 1015 is embedded in the internal thread hole 1016 to fix the tensile steel wire rope 1012, which facilitates the strengthening of the fixed tensile protection.

[0030] The anti-loosening and detachment mechanism includes a limiting abutment component located at the connection between the surface of the anti-loosening buckle plate 105 and the end of the hook 104. The limiting abutment component has an anti-loosening fixing component inside. When the fiber hanging sling body 100 is used after installation, the anti-loosening and detachment mechanism will reinforce and protect the bottom end of the anti-loosening buckle plate 105 and the inside of the hook 104, making it less likely to loosen and become unstable, and it can still provide reinforcement and protection even when the elasticity is weakened.

[0031] In order to facilitate the reinforcement of the anti-disengagement plate 105 by means of the fiber abutment assembly, in this embodiment, preferably, the limiting abutment assembly includes an extension baffle 1052 integrally disposed on the outer surface of the anti-disengagement plate 105, and a thickened abutment plate 1051 integrally disposed on the bottom surface of the hook 104. When the anti-disengagement plate 105 is elastically pressed, the bottom end of the anti-disengagement plate 105 abuts against the side of the thickened abutment plate 1051, and the upper surface of the extension baffle 1052 abuts against the upper surface of the thickened abutment plate 1051, thereby strengthening the limiting abutment and preventing deformation and loosening.

[0032] To facilitate the secure installation of the anti-loosening plate 105 after it is abutted and installed using the anti-loosening fixing component, and to prevent it from loosening and falling off, in this embodiment, preferably, the anti-loosening fixing component includes a screw 1054 threadedly connected inside the extension baffle 1052. A knob 1053 is welded to the top of the screw 1054. The thickened abutment plate 1051 has an internal threaded hole 1055 that matches the screw 1054. The bottom end of the anti-loosening plate 105 can be abutted against the side of the thickened abutment plate 1051. After the extension baffle 1052 abuts against the upper surface of the thickened abutment plate 1051, rotating the screw 1054 will embed it into the internal threaded hole 1055 to reinforce the anti-loosening plate 105 and prevent it from loosening.

[0033] The working principle and usage process of this utility model are as follows: When using this type of tensile fiber hanging sling, the fiber hanging sling body 100 is first installed and used by connecting the drive end of the external equipment through the lifting ring 103. After installation, when it is necessary to lift an object, the anti-detachment buckle plate 105 is pressed to close, and the hook 104 is engaged with the external object. The anti-detachment buckle plate 105 deforms and resets to prevent it from detaching and is pressed tightly against it. When the external equipment drives, the main fiber rope 101 is stressed and lifts the object.

[0034] Then, when the fiber hanging sling body 100 is suspended for a long time, the anti-detachment plate 105 weakens due to frequent pressing of the torsion spring. At this time, after the hook 104 is attached to the component, when the anti-detachment plate 105 resets, the bottom end of the anti-detachment plate 105 abuts against the side of the thickened abutment plate 1051, and the extension baffle 1052 closes on the upper surface of the thickened abutment plate 1051. Rotating the knob 1053 again drives the screw 1054 to be inserted into the internal threaded hole 1055, which facilitates the reset and fixed installation of the anti-detachment plate 105. Therefore, even when the elasticity weakens over a long period of time and the anti-detachment plate 105 is deformed by tight pressing, it can still effectively fix and prevent detachment, improving the anti-loosening reinforcement of the anti-detachment plate 105 when the fiber hanging sling body 100 is used after installation.

[0035] Finally, before using the fiber hanging sling body 100, the end 1014 of the tensile steel wire rope 1012 is engaged inside the installation cylinder 1013, and the fixed bolt 1015 is inserted into the internal threaded hole 1016 to fix the tensile steel wire rope 1012. After the four tensile steel wire ropes 1012 are fixedly installed, when the fiber hanging sling body 100 is under lifting force, the tensile steel wire rope 1012 provides auxiliary tensile protection for the fixing ring 1011. Under long-term lifting force, the main fiber rope 101 is less likely to be deformed or damaged, and the service life is extended. This improves the convenience of auxiliary tensile reinforcement of the main fiber rope 101 when the fiber hanging sling body 100 is used after installation.
