Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of feeding devices for grinding mills, and more specifically, to an impact-resistant and interference-resistant mining computer cable. Background Technology
[0002] Mining computer cables are signal transmission cables specifically designed for use in mining environments such as coal mines and metal mines, serving as components for computer and monitoring systems and automated equipment. Due to the complex nature of mining environments, including harsh conditions such as flammable gases, humidity, and mechanical impact, these cables require exceptional safety and durability.
[0003] Traditional mining computer cables are designed with interference resistance more in mind than mechanical protection. They typically employ simple multi-layered shielding structures and lack specialized shock-resistant structures, resulting in limited shock resistance. This design flaw makes the cables susceptible to mechanical impact damage in mining environments, affecting the stability and reliability of signal transmission. Furthermore, while the shielding structure of traditional cables can resist electromagnetic interference to some extent, its anti-interference performance is still insufficient in the complex environment of mines, failing to meet the high signal transmission requirements of modern mining equipment. Therefore, there is an urgent need for a mining computer cable that can effectively resist both shock and interference to solve these problems.
[0004] To address the aforementioned issues, existing technologies urgently need improvement. Utility Model Content

[0019] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0020] It should be noted that in the description of this specification, the terms "upper", "lower", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0021] As shown in Figures 1-3, this utility model specifically discloses an impact-resistant and interference-resistant mining computer cable, including a wire core 1, an inner shielding layer 2, and a support frame 3. The surface of the wire core 1 is covered with the inner shielding layer 2. The support frame 3 is provided with clamping grooves 303 and buffer cavities 301. The wire core 1 is detachably installed in the clamping grooves 303, and at least one buffer cavity 301 is provided between any two adjacent clamping grooves 303. In this embodiment, the support frame 3 is provided with three clamping grooves 303, which are evenly distributed along the circumference of the support frame 3. Each clamping groove 303 has a buffer cavity 301 on both sides of the circumference of the support frame 3. In this embodiment, the three clamping grooves 303 provide three buffer cavities 301.
[0022] The aforementioned three clamping slots 303 and three buffer cavities 301 are alternately arranged circumferentially on the support frame 3. This arrangement ensures that there is at least one buffer cavity 301 between every two adjacent clamping slots 303. When the cable is subjected to an impact, the external impact is absorbed and mitigated by the buffer cavity 301. At the same time, the impact force received by the conductor 1 itself is also transmitted and dispersed to the buffer cavity 301, effectively improving the cable's impact resistance. The support frame 3 simultaneously protects the inner shielding layer 2, effectively reducing or even preventing the shielding layer from breaking after the cable is subjected to an impact, thereby improving the cable's anti-interference performance. The buffer cavities 301 provided in the support frame 3 enhance the overall energy absorption and vibration damping capabilities, further improving the protection of the conductor 1 and the inner shielding layer 2, effectively enhancing the cable's impact resistance and anti-interference performance.
[0023] In this embodiment, the clamping groove 303 can be designed as U-shaped or C-shaped to better fix the wire core 1;
[0024] The buffer cavity 301 can be designed as a circle, ellipse or other shapes to optimize the absorption effect of impact force; the inner shielding layer 2 can be made of materials such as metal foil or metal braided mesh to provide good electromagnetic shielding performance; the support frame 3 can be made of high-strength plastic or metal materials to ensure its structural strength and durability.
[0025] In this embodiment, it also includes an impact-resistant casing, an outer shielding layer 4, and an insulating protective layer 6. The impact-resistant casing is provided with multiple energy-absorbing cavities 501 and is sleeved on the radial outer surface of the support frame 3. The outer shielding layer 4 covers the radial outer surface of the support frame 3, and the outer surface of the outer shielding layer 4 is attached to the inner wall surface of the impact-resistant casing. The insulating protective layer 6 covers the surface of the impact-resistant casing 5. As shown in the figure, in this embodiment, an outer shielding layer 4 is also provided, which, together with the inner shielding layer 2, forms a double-layer shielding structure. The outer shielding layer 4 can be a metal braided layer or a metal foil layer. The metal braided layer is usually woven from copper or aluminum wire, while the metal foil layer can be made of aluminum or copper foil. It should be noted that the inner shielding layer 2 and the outer shielding layer 4 are preferably made of different materials and have different structural forms to further improve the anti-interference performance. In this embodiment, the inner shielding layer 2 is a metal foil, which is wrapped around the surface of the wire core 1. At the same time, in order to avoid interference, an insulating structure can also be provided between the inner shielding layer 2 and the wire core 1; while the outer shielding layer 4 is a metal braided mesh. This embodiment also includes an impact-resistant casing, which is completely fitted over the support frame 3 and the outer shielding layer 4. The impact-resistant casing also incorporates multiple energy-absorbing cavities 501, enhancing the cable's mechanical protection performance and effectively absorbing and dispersing external impact forces through the design of the energy-absorbing cavities 501. This protects the integrity of the cable's internal structure, extends its service life, and improves its safety and reliability in complex mining environments. The shape and distribution of the energy-absorbing cavities 501 can be adjusted according to actual needs; for example, other shaped cavities, such as square or elliptical, can be used. The number and size of the energy-absorbing cavities 501 can also be optimized based on the cable's operating environment and impact resistance requirements. The impact-resistant casing can be made of high-strength engineering plastics or metal materials to further improve its impact resistance. In this embodiment, the energy-absorbing cavities 501 are cylindrical cavities extending axially, and multiple energy-absorbing cavities 501 are provided.
[0026] The impact-absorbing cavities 501 are evenly distributed around the circumference of the protective sleeve, ensuring uniform dispersion of impact force, thereby extending the cable's service life and improving safety. In this embodiment, the insulating protective layer 6 provides effective insulation protection for the cable. The insulating protective layer 6 can be made of various materials, such as rubber, polyvinyl chloride (PVC), or cross-linked polyethylene (XLPE), which have good insulation properties and mechanical strength. Specifically, the insulating protective layer 6 can be directly coated onto the outer surface of the impact-resistant protective sleeve 5 through an extrusion molding process, ensuring a tight fit between it and the sleeve.
[0027] In this embodiment, a reinforcing core strip 7 is also included. The support frame 3 has an installation channel 302 along its central axis, and the reinforcing core strip 7 is disposed within the installation channel 302. The reinforcing core strip 7 allows the cable to better disperse and absorb impact forces when subjected to external shocks. For example, when the cable is subjected to a lateral impact, the reinforcing core strip 7 can transfer the impact force to the entire support frame 3 through its rigid structure, thereby reducing local stress concentration. Furthermore, the presence of the reinforcing core strip 7 can also improve the cable's bending resistance, making it less susceptible to damage from frequent mechanical stresses in complex mining environments. The reinforcing core strip 7 can be made of high-strength materials, such as steel, carbon fiber, or composite materials, to enhance the overall structural strength of the cable. The installation channel 302 can be circular, square, or other suitable geometric shapes to ensure that the reinforcing core strip 7 can be securely embedded within it.
[0028] In this embodiment, the clamping groove 303 is circumferentially surrounded by the adjacent buffer cavity 301. The clamping groove 303 has a slot 304 for the wire core 1 to enter or be pulled out, and the buffer cavity 301 is arranged to avoid the slot 304. As shown in the figure, the buffer cavity 301 in this embodiment has an approximately fan-shaped structure. The buffer cavity 301 surrounds the clamping groove 303, which can effectively disperse and absorb external impact forces and protect the wire core 1 from damage. The design of the slot 304 facilitates the installation and removal of the wire core 1, while the arrangement of the buffer cavity 301 to avoid the slot 304 ensures that the installation of the wire core 1 is not affected during operation and will not cause additional mechanical stress to the wire core 1. The slot 304 of the clamping groove 303 can be designed as a bevel with a certain angle to facilitate the insertion and removal of the wire core 1. The buffer cavity 301 can be filled with elastic material to further enhance its energy absorption effect.
