Technical Field

[0001] This utility model relates to the field of power cable technology, specifically to a grab bucket machine cable with an irregularly shaped filled skeleton structure. Background Technology

[0002] In modern industry, grab buckets are widely used in ports, mines, waste disposal and other scenarios as core equipment for material loading, unloading and handling. During their operation, the cables bear the key task of power transmission and are directly related to the normal operation and efficiency of the equipment. However, grab bucket cables are currently facing many severe challenges in practical applications.

[0003] The frequent movement, lifting, and braking of grab buckets during operation subject the cables to continuous and intense vibration and mechanical tension. Traditional cables have limited shock absorption capabilities and are unable to buffer these external forces, making it easy for the internal cores to break and the insulation layer to be damaged. This can lead to problems such as poor contact and short circuits, which not only increase equipment maintenance costs but may also cause operation interruptions and affect production progress. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a grab bucket cable with a non-circular filled skeleton structure, which solves the problem that traditional cables have limited shock absorption performance and are unable to buffer external forces, leading to easy breakage of the internal core and damage to the insulation layer.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grab bucket cable with a non-circular filling skeleton structure, comprising a cap and a core wire, and further comprising a shock-absorbing component. The outer wall of the shock-absorbing component is fixedly connected to the outer wall of the cap, and a cooling component is fixedly connected to the inner wall of the shock-absorbing component. The cooling component comprises a venting cylinder, a skeleton body is fixedly installed on the outer wall of the venting cylinder, and the skeleton body is arranged in a linear array along the central axis of the venting cylinder. A spiral tube is fixedly connected to the inner wall of the venting cylinder through a honeycomb tube, and the spiral tube is arranged in a circular array along the central axis of the venting cylinder. The outer wall of the honeycomb tube is fixedly connected to the inner wall of the spiral tube. An inner support cylinder is fixedly connected to the outer wall of the honeycomb tube, and a through groove is formed in the wall of the inner support cylinder, and the through groove is arranged in a circular array along the central axis of the inner support cylinder.

[0006] Preferably, the end of the honeycomb tube away from the spiral tube is fixedly connected to the inner wall of the venting cylinder, and the inner wall of the skeleton body is fixedly connected to the outer wall of the wire core through an insulating sleeve. The inner wall of the insulating sleeve is fixedly connected to the outer wall of the wire core, and the insulating sleeve adopts existing technology.

[0007] Preferably, the shock-absorbing component includes an outer jacket, with shock-absorbing blocks fixedly connected to the outer wall of the outer jacket, and the shock-absorbing blocks arranged in a circular array along the central axis of the outer jacket.

[0010] This utility model provides a grab bucket crane cable with an irregularly shaped filled skeleton structure. It has the following beneficial effects: (I) This grab bucket cable with a special-shaped filled skeleton structure makes full use of the principle of air convection to achieve efficient heat dissipation through the heat dissipation structure composed of the skeleton body, vent cylinder, honeycomb tube, spiral tube and inner support cylinder in the cooling component. The unique honeycomb structure of the honeycomb tube and the spiral guide design of the spiral tube increase the heat dissipation area and enhance air flow, which can quickly dissipate the heat generated by the cable for a long time, control the cable operating temperature within a reasonable range, delay the aging of the insulation material, ensure the stability of the core performance, and extend the overall service life of the cable.

[0011] (II) The grab bucket cable with a special-shaped filled skeleton structure, through the setting of a multi-level damping system composed of damping blocks, air grooves, inner sleeves and damping plates, can absorb the vibration impact borne by the cable during the operation of the grab bucket. The compression and expansion of the air in the air groove and the elastic deformation of the damping plate work together to reduce the impact of vibration on the internal structure of the cable, such as the wire core, and avoid faults such as wire core breakage and poor contact caused by vibration, thereby improving the stability and reliability of the cable in dynamic working environment.

[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.

[0015] Please see Figure 1-6 This utility model provides a technical solution: a grab bucket cable with a non-circular filling skeleton structure, including a cover 1 and a wire core 4, and also includes a shock-absorbing component 2. The outer wall of the shock-absorbing component 2 is fixedly connected to the outer wall of the cover 1, and a cooling component 3 is fixedly connected to the inner wall of the shock-absorbing component 2. The cooling component 3 includes a venting cylinder 32, and a skeleton body 31 is fixedly installed on the outer wall of the venting cylinder 32. The skeleton body 31 is arranged in a linear array along the central axis of the venting cylinder 32. A spiral tube 34 is fixedly connected to the inner wall of the venting cylinder 32 through a honeycomb tube 35, and the outer wall of the honeycomb tube 35 is fixedly connected to the inner wall of the spiral tube 34. The outer wall is fixedly connected to the inner support cylinder 33. When the cable generates heat during the power-on process, the heat will be transferred to the honeycomb tube 35, the spiral tube 34 and the inner support cylinder 33. The unique honeycomb structure of the honeycomb tube 35 allows air to flow quickly inside it, accelerating the dissipation of heat. The spiral shape of the spiral tube 34 guides the air to flow along a specific path, further enhancing the air convection effect, and quickly transferring heat to the ventilator 32 and dissipating it into the external environment. The end of the honeycomb tube 35 away from the spiral tube 34 is fixedly connected to the inner wall of the ventilator 32. The inner wall of the skeleton body 31 is fixedly connected to the outer wall of the wire core 4 through the insulating sleeve.

[0016] The shock-absorbing component 2 includes an outer sleeve 23, with shock-absorbing blocks 21 fixedly connected to the outer wall of the outer sleeve 23. The shock-absorbing blocks 21 are arranged in a circular array along the central axis of the outer sleeve 23. An inner sleeve 24 is fixedly connected to the inner wall of the outer sleeve 23. A shock-absorbing plate 25 is fixedly connected to the inner wall of the inner sleeve 24. An air groove 22 is opened in the wall of the shock-absorbing block 21, and the air groove 22 is arranged in a linear array along the outer wall of the shock-absorbing block 21. The outer wall of the outer sleeve 23 is fixedly connected to the outer wall of the cover 1, and the inner wall of the inner sleeve 24 is fixedly connected to the outer wall of the frame body 31. When the cable is subjected to external vibration or impact from the operation of the grab bucket, the shock-absorbing block 21 first contacts and absorbs some of the energy. When the air in the air groove 22 is compressed, it dissipates the vibration energy through its own compression and expansion deformation, thus playing a role in buffering and shock absorption.

[0017] During the operation of the grab bucket machine, the cable needs to withstand frequent movement, pulling, and vibration and impact from the external environment. At the same time, it must also cope with the heat generated by prolonged power supply to ensure the stability and safety of power transmission. This grab bucket machine cable with a special-shaped filled skeleton structure solves the above problems through the coordinated cooperation of the shock absorption component 2 and the cooling component 3. Its specific working principle is as follows: The vibration damping function of the cable is mainly achieved by the vibration damping component 2. The outer jacket 23 of the vibration damping component 2 is fixedly connected to the cover 1, providing a stable outer layer support for the entire vibration damping structure. The vibration damping blocks 21 arranged in a ring array along the central axis of the outer jacket 23, and the linear array of air grooves 22 in their walls are the key structures for vibration damping. When the cable is subjected to external vibration or impact from the operation of the grab bucket, the vibration damping blocks 21 first contact and absorb some of the energy. When the air in the air grooves 22 is compressed, it dissipates the vibration energy through its own compression and expansion deformation, playing a buffering and damping role, reducing the impact of vibration on the internal structure of the cable. At the same time, the inner sleeve 24 and the vibration damping plate 25 further enhance the vibration damping effect. The inner sleeve 24 transmits the external impact force to the vibration damping plate 25. The vibration damping plate 25 performs secondary buffering and absorption of the impact force through its own elastic deformation, controlling the vibration within a small range, thereby effectively protecting the wire core 4 and other structural components inside the cable, preventing problems such as wire core 4 breakage and poor contact caused by vibration, and extending the service life of the cable.

[0018] The cooling component 3 plays a crucial role in reducing the cable's operating temperature. The frame body 31 of the cooling component 3 is arranged linearly along the central axis of the vent 32. Its inner wall is fixedly connected to the wire core 4 via an insulating sleeve, providing support and protection for the wire core 4 and ensuring good insulation performance. The vent 32, as the main cooling channel, is open to the outside air, promoting air circulation. The composite structure formed by the fixed connection of the honeycomb tube 35 and the spiral tube 34 greatly increases the heat dissipation area inside the cable. When the cable generates heat during energization, the heat is transferred to the honeycomb tube 35, the spiral tube 34, and the inner... On the support cylinder 33, the unique honeycomb structure of the honeycomb tube 35 allows air to flow rapidly inside, accelerating heat dissipation; the spiral shape of the spiral tube 34 guides airflow, further enhancing the air convection effect, quickly transferring heat to the vent cylinder 32 and dissipating it into the external environment. The inner support cylinder 33 not only provides support and maintains the structural stability of the honeycomb tube 35 and the spiral tube 34, but also assists in heat conduction and dissipation, ensuring that the cable remains within a reasonable temperature range during operation, avoiding problems such as insulation material aging and core 4 performance degradation due to excessive temperature, and ensuring the safe and reliable operation of the cable.
