Description

Technical Field

[0001] This utility model belongs to the field of crane wire rope technology, specifically relating to a crane wire rope that is resistant to breakage. Background Technology

[0002] A crane is a multi-action lifting machine that vertically lifts and horizontally moves heavy objects within a certain range. When using a crane to lift heavy objects, a wire rope needs to be installed on the drive mechanism for winding and lifting. The existing wire rope is the rope installed on the crane for lifting heavy objects, for lifting and bearing purposes.

[0003] When existing wire ropes are used on cranes, they are easily subjected to tension during the winding process of lifting heavy objects. This tension further compresses the wire rope during winding, making it difficult to reinforce connections and provide wear protection during lifting and winding. The tight contact between the wire rope surfaces during winding generates severe friction, which, over time, can cause surface damage. This makes the wire rope prone to breakage under tension, reducing its service life and hindering its ability to prevent breakage when used on cranes. Therefore, this invention proposes a breakage-resistant crane wire rope. Utility Model Content

[0004] The purpose of this utility model is to provide a fracture-resistant crane wire rope to solve the problems mentioned in the background art, such as the difficulty in strengthening the connection and wear protection of the wire rope when it is used on a crane to lift heavy objects and when it is wound up; the tight contact between the wire rope surfaces during winding up and the resulting severe friction; and the easy damage to the outer surface of the wire rope when it is wound up for a long time. The wire rope is also prone to breakage when subjected to tension during reuse, thus reducing its service life.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fracture-resistant crane wire rope, comprising a crane wire rope body, wherein the crane wire rope body includes seven main wire ropes, and the seven main wire ropes are interconnected by twisted strands. The crane wire rope body also includes:

[0006] A reinforced wear-resistant and anti-breakage mechanism is provided, and the reinforced wear-resistant and anti-breakage mechanism includes reinforced connecting components disposed on the outer surface of seven main steel wire ropes, and the outer surface of the seven main steel wire ropes is wrapped with anti-breakage and wear-resistant components.

[0007] The reinforcement mechanism includes fitting and mounting assemblies disposed at the ends of seven main wire ropes, the outer surface of which is provided with a rotational reinforcement component.

[0008] Preferably, the reinforcing connection assembly includes reinforcing connecting auxiliary steel wires at the connection point of the strands on the outer surfaces of the two main steel wire ropes, and six reinforcing connecting auxiliary steel wires are provided.

[0009] Preferably, the anti-fracture and wear-resistant component includes a flexible reinforcing steel strip wound around the outer surface of seven main steel wire ropes and six reinforcing connecting auxiliary steel wires, and the outer surface of the flexible reinforcing steel strip is provided with a wear-resistant body.

[0010] Preferably, the wear-resistant body is provided in three parts, and the wear-resistant body and the flexible reinforcing steel strip are an integral structure.

[0011] Preferably, the fitting assembly includes a reinforcing collar disposed at the end of the seven main wire ropes on the surface of the flexible reinforcing steel strip, and the reinforcing collar has seven through holes inside.

[0012] Preferably, the through hole and the reinforcing collar are an integral structure, and the main steel wire rope passes through the interior of the through hole.

[0013] Preferably, the rotary reinforcement assembly includes a fixing bolt that is threaded and rotates at the edge of the outer surface of the reinforcement collar, and four internal threaded holes are provided on one side of the end of the wear-resistant body and the flexible reinforcing steel strip, and the end of the fixing bolt is rotated and fixed with the internal thread of the internal threaded hole.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By designing a reinforced wear-resistant and fracture-resistant mechanism, six reinforcing auxiliary steel wires are twisted around the outer surface of the main wire rope, and then a flexible reinforcing steel strip is wound around the outer surface of the seven main wire ropes and the six reinforcing auxiliary steel wires. The wear-resistant body is also wound and installed accordingly. When the crane wire rope body is under tension while lifting heavy objects, the connection is strengthened by the reinforcing auxiliary steel wires. When the heavy objects are lifted and the rope is wound up, it is compressed. The flexible reinforcing steel strip and the wear-resistant body provide wear protection between the two main wire ropes, making it less prone to friction damage during compression and winding, facilitating wear protection. When the heavy objects are lifted again and the rope is under tension, it is less likely to break, thus extending the service life of the crane wire rope body and improving the reinforcement and fracture-resistant effect when the crane wire rope body is installed on the crane.

Detailed Implementation

[0023] 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.

[0024] Please see Figures 1 to 6 This utility model provides a technical solution: a fracture-resistant crane wire rope, comprising a crane wire rope body 100, the crane wire rope body 100 including seven main wire ropes 101, the seven main wire ropes 101 being interconnected by twisted strands, and the crane wire rope body 100 further comprising:

[0025] The reinforced wear-resistant and anti-breakage mechanism includes reinforced connecting components disposed on the outer surface of the seven main wire ropes 101. The seven main wire ropes 101 are wound with anti-breakage and wear-resistant components. When the crane wire rope body 100 is installed on the crane, the reinforced wear-resistant and anti-breakage mechanism strengthens the connection of the crane wire rope body 100 during lifting and winding, and at the same time, it is not easy to generate severe friction during winding and is not easy to break under tension, thereby improving the reinforcement and anti-breakage effect of the crane wire rope body 100 when installed on the crane.

[0026] To facilitate the reinforcement and lifting of the crane wire rope body 100 through the reinforced connection assembly, and to provide auxiliary protection when subjected to tension, in this embodiment, preferably, the reinforced connection assembly includes six reinforcing auxiliary steel wires 1013 at the connection point of the strands on the outer surfaces of the two main wire ropes 101. The reinforcing auxiliary steel wires 1013 can be twisted along with the main wire ropes 101 on their outer surfaces, and when using the crane wire rope body 100, the reinforcing auxiliary steel wires 1013 can be used to assist in the reinforcement connection of the crane wire rope body 100, providing protection against breakage.

[0027] In order to prevent severe frictional damage to the crane wire rope body 100 when it is subjected to tight compression during use, the anti-breakage and wear-resistant component is preferably provided in this embodiment. The anti-breakage and wear-resistant component includes a flexible reinforcing steel strip 1011 wrapped around the outer surface of the seven main wire ropes 101 and the six reinforcing connecting auxiliary wires 1013. The outer surface of the flexible reinforcing steel strip 1011 is integrally provided with three wear-resistant bodies 1012. During use, the outer surface of the main wire rope 101 is protected against wear by the flexible reinforcing steel strip 1011 and the wear-resistant bodies 1012, so that it is not prone to severe friction and breakage during long-term use.

[0028] The reinforcement mechanism includes a fitting assembly disposed at the ends of seven main steel wire ropes 101. The outer surface of the fitting assembly is provided with a rotating reinforcement component, which can wind and install the flexible reinforcing steel strip 1011 and the wear-resistant body 1012, and then reinforce the ends of the flexible reinforcing steel strip 1011 and the wear-resistant body 1012 and the main steel wire ropes 101 through the reinforcement mechanism to strengthen the fixed wear-resistant protection.

[0029] To facilitate the installation of the reinforcing collar 102 on the ends of the main wire ropes 101 to the flexible reinforcing steel strip 1011 and the wear-resistant body 1012, in this embodiment, preferably, the fitting assembly includes a reinforcing collar 102 disposed on the end surfaces of the seven main wire ropes 101 at their ends. The reinforcing collar 102 has seven through holes 1022 inside, and the main wire ropes 101 pass through the through holes 1022. By passing the main wire ropes 101 through the through holes 1022, the reinforcing collar 102 fits onto the ends of the seven main wire ropes 101. At the same time, the ends of the flexible reinforcing steel strip 1011 and the wear-resistant body 1012 are pressed tightly against the inside of the reinforcing collar 102 for easy fixing and installation.

[0030] To facilitate the installation and reinforcement of the reinforcing collar 102 by means of a rotating reinforcement assembly, in this embodiment, preferably, the rotating reinforcement assembly includes a fixing bolt 1021 with a threaded rotation at the edge of the outer surface of the reinforcing collar 102. Four internal threaded holes 1023 are provided on one side of the end of the wear-resistant body 1012 and the flexible reinforcing steel strip 1011, and the end of the fixing bolt 1021 is rotated and fixed with the internal thread of the internal threaded hole 1023. After the reinforcing collar 102 is fitted onto the end of the seven main steel wire ropes 101, the rotating fixing bolt 1021 is inserted into the internal threaded hole 1023 to reinforce the end of the flexible reinforcing steel strip 1011 and the wear-resistant body 1012, making it less prone to rotation and loosening.

[0031] The working principle and usage process of this utility model are as follows: Before use, the reinforcing connecting auxiliary steel wires 1013 are twisted together with the main steel wire ropes 101 at the connection point of the two main steel wire ropes 101, and six reinforcing connecting auxiliary steel wires 1013 are installed. Then, the flexible reinforcing steel strip 1011 is wound around the outer surface of the seven main steel wire ropes 101 and the six reinforcing connecting auxiliary steel wires 1013. After the flexible reinforcing steel strip 1011 is wound, the wear-resistant body 1012 is wound and installed accordingly. Therefore, the flexible reinforcing steel strip 1011, the wear-resistant body 1012, and the reinforcing connecting auxiliary steel wires 1013 are installed together. After installation, when the crane wire rope body 100 is installed on the crane and used, and when the crane wire rope body 100 is subjected to tension while lifting heavy objects, it is reinforced by the auxiliary steel wire 1013. At the same time, when the heavy objects are lifted and wound up, it is subjected to tight compression. The flexible reinforcing steel strip 1011 and the wear-resistant body 1012 provide wear protection between the two main wire ropes 101, making it less prone to friction damage when wound up and compressed, facilitating wear protection. When the heavy objects are lifted again and subjected to tension, it is less likely to break, extending the service life of the crane wire rope body 100 and improving the anti-breakage effect when the crane wire rope body 100 is installed on the crane.

[0032] Then, before using the crane wire rope body 100, when the flexible reinforcing steel strip 1011 and the wear-resistant body 1012 are wound around the outer surface of the main wire rope 101, the end of the flexible reinforcing steel strip 1011 is wrapped around the end of the seven main wire ropes 101 to close one turn, and the reinforcing collar 102 is fitted onto the end again. The main wire rope 101 passes through the inside of the through hole 1022, and the inner surface of the reinforcing collar 102 is pressed tightly against the surface of the wear-resistant body 1012, and the end of the fixing bolt 1021 is aligned with the inner surface of the main wire rope 101. The threaded hole 1023 is used to fix the reinforcing collar 102 and the flexible reinforcing steel strip 1011 by rotating and embedding the fixing bolt 1021 into the internal threaded hole 1023, preventing rotation and loosening. The ends of the seven main wire ropes 101 are then fixed by the mounting rings, which facilitates the reinforced and fixed installation of the wear-resistant body 1012 and the flexible reinforcing steel strip 1011. When the crane wire rope body 100 is in use, it is not easy for the flexible reinforcing steel strip 1011 and the wear-resistant body 1012 to loosen, thus strengthening the fixed wear-resistant protection.

[0033] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
