Description

Technical Field

[0001] This utility model relates to the field of power supply technology, specifically to a cable fixing device. Background Technology

[0002] In coal mining, cables can be moved into the mine shaft to facilitate power supply to the equipment inside.

[0003] In related technologies, when laying cables, it is usually necessary to manually pull the cables to move them. During this process, when the moving distance is too long, some sections of the cable will fall to the ground. At this time, when the cable is pulled, the cable section in contact with the ground will be worn, which will damage the cable. Utility Model Content

[0004] The purpose of this utility model is to provide a cable fixing device to solve related technical problems.

[0005] To achieve the above objectives, this utility model provides a cable fixing device, comprising: a supporting base plate, a cover plate, a threaded rod, a rotating disk, a movable plate, and a supporting roller assembly. The supporting roller assembly includes an upper supporting roller assembly and a lower supporting roller assembly. The cover plate is connected to the supporting base plate, and the supporting roller assembly and the movable plate are disposed within the cavity formed after the cover plate and the supporting base plate are connected. The top of the cover plate is provided with a through hole, one end of the threaded rod passes through the through hole and is connected to the movable plate, and the other end of the threaded rod is connected to the rotating disk. The upper supporting roller assembly is disposed on the side of the movable plate facing the supporting base plate, and the lower supporting roller assembly is disposed on the side of the supporting base plate facing the movable plate.

[0006] Compared with existing technologies, the cable fixing device provided by this utility model includes: a supporting base plate, a cover plate, a threaded rod, a rotating disk, a movable plate, and a support roller assembly. The support roller assembly includes an upper support roller assembly and a lower support roller assembly. The cover plate is connected to the supporting base plate, and the support roller assembly and the movable plate are disposed within the cavity formed after the cover plate and the supporting base plate are connected. The top of the cover plate has a through hole, one end of the threaded rod passes through the through hole and connects to the movable plate, and the other end of the threaded rod connects to the rotating disk. The upper support roller assembly is disposed on the side of the movable plate facing the supporting base plate, and the lower support roller assembly is disposed on the side of the supporting base plate facing the movable plate. In this way, by rotating the rotating disk, the threaded rod moves towards the lower support roller assembly, thereby controlling the movable plate to move towards the lower support roller assembly, and thus controlling the upper support roller assembly to move towards the lower support roller assembly. This allows the cable to be clamped, preventing the cable from contacting the ground, thereby improving the cable's safety and service life. Attached Figure Description

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] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0016] During coal mining, the safe and stable operation of the mine is highly dependent on the power supply. As a key carrier of power transmission, cables need to be laid to various areas underground to supply power to devices such as coal mining machines, ventilation equipment, and drainage systems to ensure their normal operation.

[0017] In practical applications, due to the complex underground environment, cables typically require manual dragging for long-distance laying. Laying cables in winding or sloping sections of tunnels is particularly challenging. Furthermore, when the cable is moved over long distances, sections inevitably come into contact with the ground. During dragging, the cable may rub against rough rocks, coal slag, or metal components, causing wear on the outer sheath and even damage to the internal insulation. This not only shortens the cable's lifespan but can also lead to safety hazards such as leakage and short circuits, affecting continuous mine production and personnel safety.

[0018] Currently, traditional cable laying methods rely mainly on manual labor or simple machinery, lacking effective anti-friction protection measures. Especially in long-distance, large-span underground environments, cables sag due to their own weight or experience uneven stress from dragging, exacerbating friction loss with the ground. Furthermore, frequent movement and adjustments can cause excessive local bending of the cable, further accelerating structural fatigue. These problems not only increase cable maintenance and replacement costs but also may lead to power outages in underground equipment due to sudden failures, threatening safe production in the mine.

[0019] To address the aforementioned problems, this utility model provides a cable fixing device, comprising: a supporting base plate, a cover plate, a threaded rod, a rotating disk, a movable plate, and a supporting roller assembly. The supporting roller assembly includes an upper supporting roller assembly and a lower supporting roller assembly. The cover plate is connected to the supporting base plate, and the supporting roller assembly and the movable plate are disposed within the cavity formed after the cover plate and the supporting base plate are connected. The top of the cover plate has a through hole, one end of the threaded rod passes through the through hole and is connected to the movable plate, and the other end of the threaded rod is connected to the rotating disk. The upper supporting roller assembly is disposed on the side of the movable plate facing the supporting base plate, and the lower supporting roller assembly is disposed on the side of the supporting base plate facing the movable plate.

[0020] Based on this, the connection between the cover plate and the supporting base plate can form a closed cavity to protect the cable placed inside the cable fixing device. The lower support roller group serves as the bottom support, while the upper support roller group's height is adjustable via a threaded rod and a rotating disc. Together, they create a clamping space for the cable, physically lifting it off the ground. This completely avoids direct friction, compression, or contamination between the cable and the ground, reducing problems such as wear and corrosion caused by rough ground, sharp objects, or damp environments. Simultaneously, the ease of operation of the rotating disc allows for flexible adjustment of the clamping force, ensuring stable cable fixation while preventing excessive compression that could damage the cable. This ensures the cable remains suspended during installation, reducing the risk of external environmental corrosion. Furthermore, it effectively cuts off the path of damage to the cable from ground factors, directly reducing potential faults and extending the cable's effective service life. It also ensures safety during installation and subsequent use. The overall structure is simple yet precisely addresses core needs, achieving a unity of protective function and practical value.

[0021] Figure 1 This diagram illustrates the overall structure of a cable fixing device according to an embodiment of the present invention. Figure 1 As shown, the cable fixing device includes: a support base plate 3, a cover plate 4, a threaded rod 5, a rotating disk 6, a movable plate 8, and a support roller group 9. The support roller group 9 includes an upper support roller group 91 and a lower support roller group 92. The cover plate 4 is connected to the support base plate 3, and the support roller group 9 and the movable plate 8 are located in the cavity formed after the cover plate 4 and the support base plate 3 are connected. The top of the cover plate 4 is provided with a through hole. One end of the threaded rod 5 passes through the through hole and is connected to the movable plate 8. The other end of the threaded rod 5 is connected to the rotating disk 6. The upper support roller group 91 is located on the side of the movable plate 8 facing the support base plate 3, and the lower support roller group 92 is located on the side of the support base plate 3 facing the movable plate 8.

[0022] like Figure 1 As shown, the threaded rod 5 can be fixedly connected to the rotating disk 6. The inner wall of the through hole at the top of the cover plate 4 can have threads that match the threaded rod 5. Thus, by rotating the rotating disk 6, the threaded rod 5 can be controlled to move along the axial direction of the through hole. The axial direction of the through hole can be perpendicular to the surface of the supporting base plate 3. Consequently, by controlling the movement of the threaded rod 5, the moving plate 8 can be moved towards the supporting base plate 3. The moving plate 8 can be parallel to the supporting base plate 3. The side wall of the cover plate 4 can also be provided with a cable inlet and a cable outlet. Thus, the cable can enter the cover plate 4 from the cable inlet and then exit the cover plate 4 from the cable outlet. The diameter of the cable inlet and cable outlet openings can be set to be relatively large, and the openings can be polished to be smooth to avoid damage to the cable.

[0023] Figure 2This diagram shows a side view of a cable fixing device according to an embodiment of the present invention. Figure 1 and Figure 2 As shown, the support roller group 9 includes an upper support roller group 91 and a lower support roller group 92. The upper support roller group 91 includes a plurality of upper support rollers arranged along a first preset direction, and the lower support roller group 92 includes a plurality of lower support rollers arranged along a second preset direction. The upper support rollers and their corresponding lower support rollers are arranged opposite to each other. An upper support roller and its oppositely arranged lower support roller can form a clamping structure, and the first preset direction can be parallel to the second preset direction. The distances between the plurality of upper support rollers and the movable plate 8 can be the same or different, and the distances between the plurality of lower support rollers and the support floor can be the same or different. The straight line formed by the cable inlet and cable outlet is parallel to the first preset direction.

[0024] Based on this, the cable can be placed on the lower support roller. Then, by rotating the rotating disk 6, the upper support roller group 91 can be moved towards the lower support roller group 92. This allows the cable to be fixed using multiple clamping structures, preventing the cable from contacting the ground. Simultaneously, the ease of operation of the rotating disk 6 allows for flexible adjustment of the clamping force, ensuring stable cable fixation while preventing excessive compression and damage. This ensures the cable remains suspended and supported throughout the laying process, reducing the risk of external environmental corrosion.

[0025] like Figure 1 and Figure 2 As shown, the support roller of this utility model can be a sliding support roller, which can be fixed or rotating. When the sliding support roller is fixed, the cable slides across the roller surface, relying on low-friction materials to reduce friction between the roller surface and the cable. When the sliding support roller is rotating, the roller moves and rolls with the cable, resulting in even less friction, making it suitable for high-speed or heavy-load scenarios. Thus, when pulling the cable from one section, the sliding support roller effectively avoids the jamming and dragging problems that may occur with traditional fixed support structures, ensuring the cable maintains a smooth trajectory during the pulling process. Even in long-distance laying operations, it reduces the effort required for pulling due to excessive resistance. Simultaneously, the gentle contact between the sliding support roller and the cable reduces wear on the cable's outer sheath, providing some protection and ensuring the cable passes smoothly through the device while minimizing unnecessary damage. In addition, the adaptive adjustment capability of the sliding support roller allows it to better adapt to cables of different diameters. Regardless of the cable thickness, it can maintain stable support and guidance through sliding contact, further ensuring the smooth passage of the cable in the laying device and improving the efficiency and safety of the overall laying operation.

[0026] Figure 3 This diagram shows the top surface of a cable fixing device according to an embodiment of the present invention. Figures 1-3 As shown, the movable plate 8 includes a bearing 81 and a support frame 82. The support frame 82 has an internal mounting area adapted to the bearing 81. The bearing 81 is fixedly installed in the mounting area, and one end of the threaded rod 5 passes through a through hole and is fixedly connected to the bearing 81. The bearing 81 has the characteristic of allowing relative rotation. When its inner side rotates with the threaded rod 5, its outer side remains relatively stationary with respect to the movable plate 8, preventing the movable plate 8 from rotating synchronously with the threaded rod 5. Simultaneously, the rotation of the threaded rod 5 is converted into axial up-and-down movement due to the propulsive action of the threaded connection. This axial force is then transmitted to the movable plate 8 through the bearing 81, enabling the movable plate 8 to move smoothly up and down, ultimately driving the upper support roller group 91 towards the lower support roller.

[0027] like Figures 1-3 As shown, since the threaded rod 5 and the cover plate 4 are threadedly connected, when the rotating disk 6 drives the threaded rod 5 to rotate, the bearing 81 can convert the rotational motion of the threaded rod 5 into the linear motion of the moving plate 8. Specifically, the rotation of the threaded rod 5 does not directly drive the moving plate 8 to rotate, but through the characteristics of the bearing 81, the moving plate 8 can move smoothly up and down, thereby precisely adjusting the distance between the upper support roller group 91 and the lower support roller group 92 to adapt to cables of different diameters. At the same time, the bearing 81 can also reduce the frictional loss between the threaded rod 5 and the moving plate 8. During the continuous rotation of the threaded rod 5 and the repeated lifting and lowering of the moving plate 8, the bearing 81 reduces the wear of the contact parts of the two through its own rolling or sliding characteristics, ensuring the long-term stable operation of the device's adjustment function, extending the service life of the components, and ensuring the smoothness and reliability of distance adjustment during cable laying.

[0028] Figure 4 This diagram shows a partial structural view of the connection between a cover plate 4 and a supporting base plate 3 according to an embodiment of the present invention. Figures 1-4 As shown, the cable fixing device also includes multiple transmission rods 11, and multiple fixing rods 10 are provided at the bottom of the cover plate 4. A represents a partial view of the connection between the cover plate 4 and the supporting base plate 3. According to partial view A, that is... Figure 4 As shown, the support base plate 3 has multiple grooves, and the side wall of the groove has a through hole for connecting to the outside. The transmission rod 11 is located in the through hole. The bottom of the cover plate 4 has multiple fixing rods 10. The side wall of the fixing rod 10 has a bayonet. The transmission rod 11 is connected to the corresponding fixing rod 10 through the bayonet. Each transmission rod 11 is provided with a spring sleeve 12.

[0029] like Figures 1-4As shown, the multiple fixing rods 10 at the bottom of the cover plate 4 can be aligned with the corresponding grooves on the support base plate 3, allowing the fixing rods 10 to be gradually inserted into the grooves. At this time, the transmission rod 11 is located in the through hole on the side wall of the groove. Under the natural extension of the spring sleeve 12, the end of the transmission rod 11 is inside the through hole, but this does not affect the insertion of the fixing rod 10 into the groove. When the fixing rod 10 is fully inserted into the groove, the snap-fit ​​on the side wall of the fixing rod 10 corresponds to the position of the through hole. At this time, the transmission rod 11 moves towards the inside of the groove under the elastic force of the spring sleeve 12, and its end is snapped into the snap-fit ​​of the fixing rod 10. Thus, the transmission rod 11 can form a snap-fit ​​connection with the fixing rod 10 through the snap-fit. The combined action of the multiple fixing rods 10 and the multiple transmission rods 11 can firmly fix the cover plate 4 onto the support base plate 3, completing the installation.

[0030] As can be seen, the locking connection between the fixed rod 10 and the transmission rod 11 via the bayonet provides a stable limit for the cover plate 4, preventing it from loosening or falling off during device movement or cable laying, and ensuring the reliability of the connection between the cover plate 4 and the supporting base plate 3. Compared to traditional bolt connections, the locking structure between the transmission rod 11 and the fixed rod 10 eliminates the need for additional tools; the cover plate 4 can be installed and removed simply by operating the transmission rod 11, simplifying the operation process and improving efficiency during cable placement, removal, or device maintenance. Furthermore, the spring sleeve 12 on the transmission rod 11 provides elastic cushioning. When the cover plate 4 is subjected to slight vibration or external impact, the spring sleeve 12 absorbs some of the force, reducing rigid wear on components, extending the device's service life, and also ensuring a tighter locking connection.

[0031] like Figures 1-4 As shown, the inner side of the cover plate 4 is provided with a sliding groove 13, and the side wall of the movable plate 8 is provided with a limiting slider 14, which is engaged in the sliding groove 13. During the assembly of the cable fixing device, the limiting slider 14 on the side wall of the movable plate 8 can be aligned with the inner side of the cover plate 4, and the limiting slider 14 can be pushed in along the opening direction of the sliding groove 13 until it is fully inside. At this point, the limiting slider 14 and the sliding groove 13 form a tight engaging fit, and the movable plate 8 is suspended inside the cover plate 4 by this structure. Based on this, when the rotating disk 6 drives the threaded rod 5 to rotate, the threaded rod 5 pushes the movable plate 8 to move through the bearing 81. At this time, the limiting slider 14 will slide synchronously along the track of the sliding groove 13, restricting the movement of the movable plate 8 while guiding it to make linear motion, thus adjusting the distance between the upper support roller group 91 and the lower support roller group 92.

[0032] Therefore, the limiting slider 14 is locked in the sliding groove 13, which can strictly constrain the movement trajectory of the moving plate 8, so that the moving plate 8 can only move smoothly along the extension direction of the sliding groove 13, avoiding the moving plate from shifting, tilting or rotating during the adjustment with the threaded rod 5, ensuring that the distance between the upper support roller group 91 and the lower support roller group 92 is accurately adjusted, thereby stabilizing and limiting cables of different diameters.

[0033] like Figures 1-4 As shown, the cable fixing device also includes a support platform 1, and a support base plate 3 is detachably mounted on the support platform 1. In practical applications, the support base plate 3 can be aligned with a preset installation position on the support platform 1 to ensure a detachable connection between the support base plate 3 and the support platform 1. Specifically, the detachable structure can be the connection method between the fixing rod 10 and the transmission rod 11 in this embodiment, thereby allowing the support base plate 3 to be detachably mounted on the support platform 1, enabling the device to be flexibly disassembled or combined according to actual operational needs. Here, the detachable structure can also be any other detachable structure in related technologies, and no specific limitation is imposed.

[0034] like Figures 1-4 As shown, the cable fixing device also includes multiple movable wheels 2, which are detachably mounted on the bottom of the support platform 1. In practical applications, the support base plate 3 can be aligned with the preset installation position of the support platform 1 to ensure that the multiple movable wheels 2 and the support platform 1 are detachably connected. Specifically, the detachable structure can be the connection method between the fixing rod 10 and the transmission rod 11 in this embodiment, thereby allowing the multiple movable wheels 2 to be detachably mounted on the bottom of the support platform 1, enabling the device to be flexibly adjusted according to the terrain conditions in the coal mine.

[0035] In summary, this utility model provides a cable fixing device, including: a supporting base plate, a cover plate, a threaded rod, a rotating disk, a movable plate, and a supporting roller assembly. The supporting roller assembly includes an upper supporting roller assembly and a lower supporting roller assembly. The cover plate is connected to the supporting base plate, and the supporting roller assembly and the movable plate are disposed in the cavity formed after the cover plate and the supporting base plate are connected. The top of the cover plate is provided with a through hole, one end of the threaded rod passes through the through hole and is connected to the movable plate, and the other end of the threaded rod is connected to the rotating disk. The upper supporting roller assembly is disposed on the side of the movable plate facing the supporting base plate, and the lower supporting roller assembly is disposed on the side of the supporting base plate facing the movable plate.

[0036] Based on this, the connection between the cover plate and the supporting base plate can form a closed cavity to protect the cable placed inside the cable fixing device. The lower support roller group serves as the bottom support, while the upper support roller group's height is adjustable via a threaded rod and a rotating disc. Together, they create a clamping space for the cable, physically lifting it off the ground. This completely avoids direct friction, compression, or contamination between the cable and the ground, reducing problems such as wear and corrosion caused by rough ground, sharp objects, or damp environments. Simultaneously, the ease of operation of the rotating disc allows for flexible adjustment of the clamping force, ensuring stable cable fixation while preventing excessive compression that could damage the cable. This ensures the cable remains suspended during installation, reducing the risk of external environmental corrosion. Furthermore, it effectively cuts off the path of damage to the cable from ground factors, directly reducing potential faults and extending the cable's effective service life.
