Description

Technical Field

[0001] This utility model relates to the field of wire and cable technology, specifically a grab bucket machine cable that is not prone to longitudinal core breakage. Background Technology

[0002] In ports, mines and other fields, grab buckets are important material handling equipment, and their operational stability and reliability are of paramount importance. Grab bucket cables are key components that connect grab buckets to power supply or control systems.

[0003] Grab bucket crane cables undergo frequent stretching, bending, and torsion during operation. Longitudinal core breakage in grab bucket crane cables is mainly caused by mechanical stress, environmental factors, cable quality, and improper use and maintenance. Regarding mechanical stress, the tensile, bending, and torsional forces exerted on the cable during grab bucket crane operation can cause fatigue cracks in the internal core wires, which gradually propagate and eventually lead to core breakage. Environmental factors such as extreme temperatures, chemical corrosion, and humidity accelerate the aging of cable materials and weaken the core wire strength. Defects in materials or improper processes during cable production can also reduce cable performance and service life. Furthermore, overload operation, lack of maintenance, and incorrect installation also increase the risk of core breakage. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a grab bucket cable that is less prone to longitudinal core breakage, solving the problem of longitudinal core breakage in grab bucket cables caused by mechanical stress, environmental factors, and other factors.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grab bucket cable that is not prone to longitudinal core breakage, comprising: a cable core, the outer wall of which is fitted with a protective device, the protective device protecting the cable core by covering it, the outer wall of which is fitted with a movable device, the protective device including a sheath, the outer wall of which is bonded with glass wool, and the outer wall of which is fitted with a rubber fixing ring. This invention provides a covering protection for the cable core by setting a protective device, wherein the sheath is in direct contact with the cable core, which can effectively isolate the cable core from scratches by sharp external objects and reduce the risk of core breakage due to physical damage.

[0006] Preferably, the inner wall of the sheath is in contact with the outer wall of the cable core. The glass wool is soft and has good cushioning properties. When the cable is subjected to external pressure or collision, it can absorb the impact energy and further protect the cable core. The rubber retaining ring can firmly combine the sheath and the glass wool to prevent the protective device from shifting or falling off during use, ensuring the durability and stability of the protective effect.

[0007] Preferably, the outer wall of the rubber fixing ring is fitted with a diamond mesh. The diamond mesh fitted on the outer wall of the rubber fixing ring greatly improves the overall tensile strength, tear resistance and wear resistance of the cable. The high-strength structure of the diamond mesh can withstand greater external forces.

[0008] Preferably, the outer wall of the diamond mesh contacts the inner wall of the movable device. When the cable is subjected to longitudinal tension, it can disperse the stress and prevent the cable core from breaking due to excessive local stress. At the same time, its wear-resistant properties can effectively resist wear factors in the external environment and extend the service life of the cable.

[0009] Preferably, the movable device includes an insulating outer ring, the outer wall of which has an arc-shaped groove, and the inner wall of the arc-shaped groove is arranged in a linear array along the outer wall of the insulating outer ring. The insulating outer ring and the arc-shaped groove on its inner wall in the movable device provide flexible movement space for the cable.

[0010] Preferably, the inner wall of the insulating outer ring contacts the outer wall of the diamond mesh. When the grab bucket is in operation and the cable needs to be bent and stretched frequently, the arc groove can allow relative displacement between the insulating outer ring and the protective device, reduce stress concentration in the bending part of the cable, make the cable core more uniform when under stress, and reduce the possibility of fatigue fracture of the core wire due to repeated bending.

[0011] This utility model provides a grab bucket crane cable that is less prone to longitudinal core breakage. It has the following beneficial effects: This utility model, through the combination of protective and movable devices, effectively isolates the cable core from scratches by sharp external objects, reducing the risk of core breakage due to physical damage. The glass wool is soft and has good cushioning properties, absorbing the impact energy of external pressure or collision, further protecting the cable core. The rubber fixing ring securely combines the sheath with the glass wool. The diamond mesh on the outer wall of the rubber fixing ring greatly improves the overall tensile, tear, and abrasion resistance of the cable, enabling it to withstand greater external forces. When the cable is subjected to longitudinal tension, it can disperse stress, preventing the cable core from breaking due to excessive local stress. The arc groove allows relative displacement between the outer insulation ring and the protective device, reducing stress concentration at bending points and making the cable core more evenly stressed, thus reducing the possibility of fatigue fracture of the core wire due to repeated bending.

[0014] 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. Example

[0015] Please see Figure 1-3 This utility model provides a technical solution: a grab bucket cable that is not easily broken in the longitudinal direction, comprising: The cable core 1 has a protective device 2 on its outer wall. The protective device 2 protects the cable core 1 by covering it. The outer wall of the protective device 2 has a movable device 3. The cable core 1 is protected by the protective device 2 on its outer wall to prevent breakage. The movable device 3 allows the cable core 1 to move flexibly during the protection process. The protective device 2 includes a sheath 20, the outer wall of which is bonded with glass wool 21. A rubber retaining ring 22 is fitted onto the outer wall of the glass wool 21. The inner wall of the sheath 20 is in contact with the outer wall of the cable core 1. The sheath 20 in the protective device 2 fits tightly against the outer wall of the cable core 1. Because the outer wall of the cable core 1 is fitted with the sheath 20, the sheath 20 forms the first physical protective barrier, effectively preventing sharp objects from directly scratching and puncturing the cable core 1, thus avoiding breakage of the cable core 1 due to mechanical damage. The outer wall of the sheath 20 is fitted with glass wool 21, which has a... Soft and with good cushioning performance, when the cable is squeezed or collided by external force, the glass wool 21 can absorb the impact energy through its own deformation, evenly disperse the impact force, prevent the impact force from acting directly on the cable core 1, and further reduce the risk of damage to the cable core 1. The rubber fixing ring 22 is sleeved on the outer wall of the glass wool 21, and the sheath 20 and the glass wool 21 are firmly combined by tightly wrapping. This not only prevents the relative displacement of the two during the use of the cable, but also ensures that the fixed position of the entire protection device 2 on the cable is stable, so that the protection device 2 always plays a protective role. The outer wall of the rubber fixing ring 22 is fitted with a diamond mesh 23. The outer wall of the diamond mesh 23 contacts the inner wall of the movable device 3. The diamond mesh 23 fitted on the outer wall of the rubber fixing ring 22 significantly improves the mechanical protection performance of the cable due to its high-strength mesh structure. When the cable is subjected to longitudinal tension, the diamond mesh 23 can use its own structural characteristics to evenly distribute the tension to the entire cross-section of the cable, preventing the cable core 1 from being subjected to excessive tension and breaking. At the same time, the high strength and wear resistance of the diamond mesh 23 enable it to resist abrasive factors in the external environment. For example, during the operation of the grab bucket machine, the cable may rub against surrounding objects. The diamond mesh 23 can effectively reduce the damage of such friction to the internal structure of the cable, extend the service life of the cable, and thus ensure the integrity of the cable core 1 during long-term use.

[0016] The movable device 3 includes an insulating outer ring 30. An arc-shaped groove 31 is formed on the outer wall of the insulating outer ring 30. The inner wall of the arc-shaped groove 31 is arranged in a linear array along the outer wall of the insulating outer ring 30. The inner wall of the insulating outer ring 30 contacts the outer wall of the diamond mesh 23. The arc-shaped groove 31 formed on the inner wall of the insulating outer ring 30 in the movable device 3 provides flexible space for the cable to bend and stretch during the operation of the grab bucket. When the grab bucket performs grabbing, lifting, and moving operations, the cable needs to change shape frequently. At this time, the insulating outer ring 30 and the protective device 2 can generate relative displacement through the arc-shaped groove 31. This relative displacement allows the stress of the cable at the bending part to be effectively dispersed, avoiding stress concentration in a certain local position of the cable, thereby reducing the possibility of fatigue cracks or even breakage of the cable core 1 due to repeated bending. In addition, the insulating outer ring 30 itself has good insulation performance. While ensuring the flexible movement of the cable, it can also further enhance the overall insulation effect of the cable and improve the safety of the cable during use.

[0017] During use, the cable core 1 is protected by the protective device 2 sleeved on the outer wall to prevent breakage, and its movable device 3 allows the cable core 1 to move flexibly during the protection process. First, the sheath 20 in the protection device 2 is tightly fitted to the outer wall of the cable core 1. Since the outer wall of the cable core 1 is fitted with the sheath 20, the sheath 20 forms the first physical protective barrier, which can effectively block the direct scratching and puncture of the cable core 1 by sharp objects from the outside, and avoid the cable core 1 from breaking due to mechanical damage. Since the outer wall of the sheath 20 is fitted with glass wool 21, which is soft and has good cushioning performance, when the cable is squeezed or collided by external force, the glass wool 21 can absorb the impact energy through its own deformation, and evenly disperse the impact force, preventing the impact force from acting directly on the cable core 1, and further reducing the risk of damage to the cable core 1. The rubber fixing ring 22 is fitted on the outer wall of the glass wool 21, and the sheath 20 and the glass wool 21 are firmly combined by tightly wrapping. This not only prevents the relative displacement of the two during the use of the cable, but also ensures that the fixed position of the entire protection device 2 on the cable is stable, so that the protection device 2 always plays a protective role. The diamond mesh 23 fitted on the outer wall of the rubber fixing ring 22 significantly improves the mechanical protection performance of the cable due to its high-strength mesh structure. When the cable is subjected to longitudinal tension, the diamond mesh 23 can use its own structural characteristics to evenly distribute the tension to the entire cross-section of the cable, preventing the cable core 1 from being subjected to excessive tension and breaking. At the same time, the high strength and wear resistance of the diamond mesh 23 enable it to resist abrasive factors in the external environment. For example, during the operation of the grab bucket machine, the cable may rub against surrounding objects. The diamond mesh 23 can effectively reduce the damage of such friction to the internal structure of the cable, extend the service life of the cable, and thus ensure the integrity of the cable core 1 during long-term use.

[0018] The arc-shaped groove 31 on the inner wall of the insulating outer ring 30 in the movable device 3 provides flexible space for the cable to bend and stretch during the operation of the grab bucket. When the grab bucket performs operations such as grabbing, lifting, and moving, the cable needs to change shape frequently. At this time, the insulating outer ring 30 and the protective device 2 can generate relative displacement through the arc-shaped groove 31. This relative displacement allows the stress of the cable at the bending part to be effectively dispersed, avoiding stress concentration in a certain local position of the cable, thereby reducing the possibility of fatigue cracks or even breakage of the cable core 1 due to repeated bending. In addition, the insulating outer ring 30 itself has good insulation performance, which can further enhance the overall insulation effect of the cable while ensuring the flexible movement of the cable, and improve the safety of the cable during use.
