Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a cable fixing fastener for power engineering. Background Technology

[0002] In the field of power engineering, the stable fixing of cables is a key link in ensuring the safe and reliable transmission of power, which directly affects the overall operating efficiency and service life of the power system. With the rapid development of the power industry, cable laying scenarios are becoming increasingly complex, covering various environments such as underground tunnels, high-altitude installations, and building walls. This places higher demands on the performance of cable fixing devices. For some thicker cables, it is difficult to straighten them manually during transportation, especially in confined spaces or underground, which is time-consuming and labor-intensive. In such cases, mechanical power is needed, using a purely mechanical hand-cranked screw to straighten the cable, facilitating subsequent transportation without jamming. Utility Model Content

[0003] The purpose of this invention is to solve the problem of traditional cable conveying methods in complex environments, such as humid tunnels and high-temperature machine rooms. These methods involve taking the cables out of a large circular tray, which often requires two or more people to carry due to the thickness of the cables. The cables also need to be straightened for easier transport, but manual straightening is time-consuming and labor-intensive. In harsh conditions, it may cause wear and tear on the outer sheath. A more convenient device is needed to lay the cables flat and straighten them, solving the problem of cumbersome manual handling and operation.

[0004] This utility model achieves the above objectives through the following technical solutions: A cable fixing fastener for power engineering includes two opposing support frames. A hand-cranked screw structure is mounted on the upper end of each support frame. A cable straightening structure is movably connected to the upper end of the hand-cranked screw structure. A cable locking structure is mounted on the opposite end of the cable straightening structure. The cable locking structure is fixedly connected to one end of each support frame. A cable passes through the cable straightening structure and the cable locking structure. The hand-cranked screw structure includes a fixed base plate. Slide rails are mounted on both sides of the upper end of the fixed base plate. A slider is mounted on each slide rail. A hand-cranked screw is positioned in the middle of each slide rail, and a bearing is mounted on the hand-cranked screw. The bearing is fixedly connected to the cable straightening structure. The cable straightening structure is moved laterally by the combination of the slide rail and the slider, which is used for the lateral straightening of the cable. The overall structure forms a stable support base through the opposing support frames. The combination of the hand-cranked screw structure with the slide rail and slider realizes the lateral controllable movement of the cable straightening structure. The lateral position of the cable can be adjusted in a targeted manner to solve the problem of uneven force caused by deviation during cable laying, ensure that the cable is in a preset reasonable position, reduce the risk of wear or breakage during long-term use, and at the same time take into account the adjustability and stability of the structure to adapt to the cable fixing needs in different scenarios.

[0005] Furthermore, the cable straightening structure includes a T-shaped base plate, a U-shaped block at the upper end of the T-shaped base plate, a U-shaped cover at the upper end of the U-shaped block, fixing plates on both sides of the T-shaped base plate, a rotating shaft on the fixing plates, a pressing block on the rotating shaft, a sleeve on the U-shaped block, and an elastic buckle on one side of the lower end of the sleeve. The components of the cable straightening structure (T-shaped base plate, U-shaped block, U-shaped cover, pressing block, etc.) form a modular clamping structure. The T-shaped base plate provides a stable bearing foundation, the cooperation of the U-shaped block and the U-shaped cover forms a wrap-around receiving space for the cable, the pressing block connected to the rotating shaft can flexibly adjust the clamping angle, and the sleeve and elastic buckle facilitate the quick opening and closing and locking of the U-shaped cover. Overall, it improves the flexibility and ease of operation of cable clamping, and can adapt to cables of different diameters and achieve reliable fixation.

[0006] Furthermore, the U-shaped cover and the U-shaped block are movably connected by a hinge. This connection ensures the stability of the U-shaped cover's opening and closing process, avoiding the problem of easy loss of components in traditional detachable connections. On the other hand, the hinge structure allows the U-shaped cover to be smoothly flipped, facilitating the quick insertion of cables or the inspection and maintenance of cables, reducing operating steps and improving installation and maintenance efficiency.

[0007] Furthermore, a groove is provided on one side of the upper end of the U-shaped cover and is assembled with the lower pressure block for locking the cable. The cable straightening structure is the same as the cable locking structure.

[0008] Furthermore, the inner side of the U-shaped cover is provided with anti-slip texture.

[0009] Compared with the prior art, the beneficial effects of this utility model are: 1. Cable straightening is driven by a hand-cranked screw with a purely mechanical structure, replacing the traditional method of multiple people handling and manual straightening. Especially for laying thick cables in confined spaces or underground environments, it can reduce manpower input by more than 50%, while avoiding cable sheath wear caused by improper manual operation and improving construction safety.

[0010] 2. Combining the lateral adjustment function of the slide rail slider with the modular clamping design of the cable straightening structure, it can not only accurately adjust the lateral position of the cable by hand-cranking the screw to eliminate deviation, but also reliably fix cables of different diameters by combining U-shaped blocks, pressure blocks and anti-slip textures, solving the problems of jamming and wear caused by uneven force in traditional fixing methods, and ensuring smooth cable transportation.

[0011] 3. The overall structure adopts opposing support frames to form a stable foundation, and the component connections take into account both rigidity and flexibility (such as hinge connections and elastic buckles), making it less prone to rust or jamming in complex environments such as humid tunnels and high-temperature machine rooms; at the same time, the modular design facilitates quick opening and closing for maintenance, improving maintenance efficiency by more than 40% compared to traditional straps or fixing clamps, and can maintain a stable fixing effect for a long time.

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.

[0014] Combination Figure 1-3 As shown, a cable fixing fastener for power engineering includes two opposing support frames 1. A hand-cranked screw structure 2 is mounted on the upper end of each support frame 1. A cable straightening structure 3 is movably connected to the upper end of the hand-cranked screw structure 2. A cable locking structure 4 is mounted on the opposite end of the cable straightening structure 3. The cable locking structure 4 is fixedly connected to one end of the support frame 1. A cable 5 passes through the cable straightening structure 3 and the cable locking structure 4. The hand-cranked screw structure 2 includes a fixed base plate 21. Slide rails 22 are mounted on both sides of the upper end of the fixed base plate 21. Slider blocks 23 are mounted on each slide rail 22. A hand-cranked screw 24 is mounted in the middle of the slide rail 22, and a shaft is mounted on the hand-cranked screw 24. Bearing 25 is fixedly connected to cable straightening structure 3. The cable straightening structure 3 is moved laterally by the combination of slide rail 22 and slider 23 for the lateral straightening of cable 5. The overall structure forms a stable support base through opposing support frames. The combination of hand-cranked screw structure with slide rail and slider realizes the lateral controllable movement of cable straightening structure, which can be used to adjust the lateral position of cable, solve the problem of uneven force caused by offset during cable laying, ensure that cable is in the preset reasonable position, reduce the risk of wear or breakage during long-term use, and at the same time take into account the adjustability and stability of the structure to adapt to the cable fixing needs in different scenarios.

[0015] The cable straightening structure 3 includes a T-shaped base plate 31, a U-shaped block 32 at the upper end of the T-shaped base plate 31, a U-shaped cover 33 at the upper end of the U-shaped block 32, fixing plates 34 on both sides of the T-shaped base plate 31, a rotating shaft 35 on the fixing plate 34, a pressing block 36 on the rotating shaft 35, a sleeve 37 on the U-shaped block 32, and an elastic buckle 38 on one side of the lower end of the sleeve 37. The components of the cable straightening structure (T-shaped base plate, U-shaped block, U-shaped cover, pressing block, etc.) form a modular clamping structure. The T-shaped base plate provides a stable bearing foundation, the cooperation of the U-shaped block and the U-shaped cover forms a wrap-around receiving space for the cable, the pressing block connected to the rotating shaft can flexibly adjust the clamping angle, and the sleeve and elastic buckle facilitate the clamping of the U-shaped cover. The quick opening, closing, and locking mechanism significantly improves the flexibility and ease of operation of cable clamping, enabling it to accommodate cables of different diameters and achieve reliable fixation. The U-shaped cover 33 and U-shaped block 32 are connected by a hinge, ensuring stability during the opening and closing process and avoiding the problem of easily lost components in traditional detachable connections. Furthermore, the hinge structure allows for smooth flipping of the U-shaped cover, facilitating quick cable insertion or maintenance, reducing operational steps, and improving installation and maintenance efficiency. A groove is provided on one side of the upper end of the U-shaped cover 33, which assembles with the lower pressure block 36 to lock the cable 5 in place. The inner side of the U-shaped cover 33 has anti-slip textures, and the cable straightening structure 3 and cable locking structure 4 have the same structure.

[0016] Working principle: First, the cable is placed by operating the elastic buckles of the cable straightening structure and the cable locking structure to disengage them from the sleeve's locking state. Then, the U-shaped cover is opened by flipping around the hinge, and the cable to be fixed is passed between the two structures and placed in the U-shaped block's receiving space. The U-shaped cover is then flipped back to the closed state, and the elastic buckles re-engage with the sleeve to lock the U-shaped cover, completing the initial positioning of the cable. Second, the cable is tightly fixed by rotating the rotating shaft on both sides of the T-shaped base plate after the U-shaped cover is closed, causing the lower pressure block to rotate around the shaft, so that one end of the lower pressure block is embedded in the groove at the upper end of the U-shaped cover. By adjusting the angle of the rotating shaft, the pressure of the lower pressure block on the U-shaped cover can be controlled, thereby adjusting the clamping force on the cable. At the same time, the anti-slip texture on the inside of the U-shaped cover increases the friction with the cable surface, preventing the cable from slipping during the fixing process and ensuring that cables of different diameters can be reliably clamped. Finally, the lateral position of the cable is corrected. If the cable deviates laterally during installation, rotating the hand-cranked screw in the hand-cranked screw structure, utilizing the threaded engagement between the screw and the bearing, will cause the cable straightening structure to move laterally along the slide rail (the cooperation between the slider and the slide rail ensures smooth movement). Since the cable straightening structure and the cable locking structure together clamp the cable, the movement of the straightening structure will pull the cable to adjust its position synchronously until the cable is on the preset, reasonable path, thereby solving the problem of uneven force caused by deviation and ensuring the stability of the cable during long-term use.
