Description

Technical Field

[0001] This utility model relates to the field of protective devices, specifically a cable protection device for iron towers. Background Technology

[0002] In power transmission engineering, towers serve as the core support structure for cable erection. Protective devices must be installed at cable connections, corners, and exposed parts to prevent cable wear and breakage caused by factors such as wind and rain vibration, tower friction, and external collisions, thus ensuring the safety and stability of power transmission. Currently available tower cable protection devices still face many technical challenges when dealing with tower components of different specifications, complex installation environments, and long-term outdoor use requirements.

[0003] In the process of realizing this utility model, the inventors discovered that at least the following problems in the prior art have not been solved. In use, traditional cable protection devices mostly use fixed clamps and cable ties, and most of them are designed with fixed size. One set of devices can only be adapted to a single specification of pole. For thinner poles, the clamps are loose and easy to shift or shake. For thicker poles, they cannot achieve effective wrapping, the protective gap is too large, and the protective meaning is lost. Secondly, the fixed structure lacks stability and is prone to loosening and failure after long-term use. Outdoor towers are constantly affected by natural environmental factors such as strong winds, rain, snow, and temperature changes, making the fixed structure of cable protection devices prone to loosening. Traditional clamps mostly rely on the friction of bolts for fixation, and under vibration, the bolts are prone to loosening, leading to an increase in the gap between the clamp and the tower members. The cable loses effective restraint and subsequently experiences friction and wear against the tower. Therefore, a new technical solution is needed to address this issue. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a tower cable protection device to solve the technical problem that the current tower cable protection mainly uses fixed clamps and cable ties, which are easily aged and broken due to long-term exposure to wind vibration and thermal expansion and contraction, leading to cable detachment.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: design a tower cable protection device, including a main clamp and a secondary clamp. The main clamp has through grooves on both sides, and convex-shaped limiting grooves are symmetrically opened on both sides of the through grooves. A ratchet plate is movably connected inside the through grooves, and an adjusting threaded rod is rotatably connected to one side of the ratchet plate. Two U-shaped limiting blocks are fixedly connected to both ends of the auxiliary clamp. Each pair of U-shaped limiting blocks has an internal groove. A fixed shaft is fixedly connected to the internal groove. A torsion spring is sleeved on the outside of the fixed shaft. Both the fixed shaft and the torsion spring are located in the mounting hole of the limiting tooth plate.

[0006] Preferably, a connecting column is fixedly connected to the top of the main clamp, and the other end of the connecting column is fixedly connected to one end of the mounting plate.

[0007] Preferably, one end of the convex-shaped limiting groove is connected to the bottom end of the main clamp, and the size of the ratchet plate matches the size of the through groove.

[0008] Preferably, the other end of the adjusting threaded rod is threaded into the inside of the support frame and extends to its other side. The two ends of the support frame span the through groove and are fixedly connected to the outer side of the main clamp.

[0009] Preferably, the size of the convex-shaped limiting block matches the size of the convex-shaped limiting groove, and it is slidably connected to its inner wall.

[0010] Preferably, the mounting hole penetrates the interior of one end of the limiting tooth plate, one end of the limiting tooth plate is rotatably connected to the inner wall of the built-in groove, and the size of the built-in groove matches the size of the limiting tooth plate.

[0011] Preferably, one end of the torsion spring abuts against the outside of the fixed shaft, and the other end of the torsion spring abuts against the inner wall of the mounting hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention applies a continuous torque to the limiting tooth plate through elastic deformation, ensuring that the limiting tooth plate always tends to rotate towards the ratchet plate. When the secondary clamp slides along the convex-shaped limiting groove, the toothed end of the limiting tooth plate engages with the toothed end of the ratchet plate. Utilizing the one-way locking characteristic of the ratchet, only the secondary clamp is allowed to move closer to the main clamp, preventing it from loosening in the opposite direction. If the spacing needs to be adjusted or disassembled, simply rotate the adjusting threaded rod, allowing the adjusting threaded rod to move the ratchet plate inside the through groove, thereby disengaging the toothed end of the ratchet plate from the limiting tooth plate. This achieves the dual functions of fastening and locking, as well as flexible adjustment, ensuring that the clamp does not loosen during long-term use and improving the stability of cable protection. The elastic torque of the torsion spring keeps the limiting tooth plate engaged with the ratchet plate, allowing for quick reset and locking even in vibrating environments, preventing the clamp from loosening. At the same time, the enclosed design with the built-in groove protects the torsion spring and the fixed shaft from external environmental corrosion, extending the service life of the locking structure and ensuring a long-term stable locking effect. The main clamp and the auxiliary clamp constitute the core fixing structure for cable protection, used to fit the tower members and wrap the protective cable. The through grooves on both sides of the main clamp provide movement space for the ratchet plate. The U-shaped limiting grooves on both sides of the through groove and the U-shaped limiting blocks at both ends of the auxiliary clamp form a sliding fit, restricting the auxiliary clamp to move only along the through groove direction, avoiding lateral displacement during installation. Rotating the adjusting threaded rod will convert its threaded connection with the support frame into a linear driving force, pushing the ratchet plate to slide along the through groove. When the ratchet plate moves forward, it moves closer to the limiting plate, reducing the distance between them to achieve the limiting effect; when the ratchet plate moves backward, the distance increases, allowing the ratchet plate to disengage from the limiting plate, enabling quick disassembly of the main clamp and the auxiliary clamp.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments: Example 1: A cable protection device for iron towers, see [link / reference] Figures 1 to 5 It includes a main clamp 1 and a secondary clamp 11. The main clamp 1 has through grooves 12 on both sides. The through grooves 12 have symmetrical convex-shaped limiting grooves 13 on both sides. The through grooves 12 are movably connected to a ratchet plate 14. One side of the ratchet plate 14 is rotatably connected to an adjusting threaded rod 15. The other end of the adjusting threaded rod 15 is threaded to the inside of the support frame 23 and extends to the other side. The two ends of the support frame 23 span the through grooves 12 and are fixedly connected to the outer side of the main clamp 1. The main clamp 1 and the auxiliary clamp 11 constitute the core fixing structure for cable protection, used to fit the tower pole and wrap the protective cable. The through grooves 12 on both sides of the main clamp 1 provide movement space for the ratchet plate 14. The U-shaped limiting grooves 13 on both sides of the through groove 12 and the U-shaped limiting blocks 16 at both ends of the auxiliary clamp 11 form a sliding fit, restricting the auxiliary clamp 11 to move only along the through groove 12, avoiding lateral displacement during installation. Rotating the adjusting threaded rod 15 will convert its threaded connection with the support frame 23 into a linear driving force, pushing the ratchet plate 14 to slide along the through groove 12. When the ratchet plate 14 moves forward, it moves closer to the limiting tooth plate 24, reducing the distance between them to achieve the limiting effect. When the ratchet plate 14 moves backward, the distance increases, allowing the ratchet plate 14 to disengage from the limiting tooth plate 24, thus enabling the main clamp 1 and the auxiliary clamp 11 to be disassembled.

[0020] Two U-shaped limiting blocks 16 are fixedly connected to both ends of the secondary clamp 11. Each pair of U-shaped limiting blocks 16 has an internal groove 17. A fixed shaft 18 is fixedly connected to the internal groove 17. A torsion spring 19 is sleeved on the outside of the fixed shaft 18. The fixed shaft 18 and the torsion spring 19 are both located in the mounting hole 2 of the limiting tooth plate 24. Within the built-in grooves 17 of the U-shaped limiting blocks 16 at both ends of the secondary clamp 11, the fixed shaft 18, torsion spring 19, and limiting tooth plate 24 form an elastic locking structure. The limiting tooth plate 24 is sleeved on the outside of the fixed shaft 18 through the mounting hole 2. The torsion spring 19 is sleeved on the fixed shaft 18, with its two ends abutting against the inner walls of the fixed shaft 18 and the mounting hole 2, respectively. Through elastic deformation, a continuous torque is applied to the limiting tooth plate 24, so that the limiting tooth plate 24 always has the tendency to rotate in the direction of the ratchet plate 14. When the secondary clamp 11 slides along the U-shaped limiting groove 13, the limiting tooth plate 24... The toothed end of the ratchet plate 14 engages with the toothed end of the ratchet plate 14. Utilizing the one-way locking characteristic of the ratchet, only the auxiliary clamp 11 is allowed to move towards the main clamp 1 (in the fastening direction), preventing it from loosening in the opposite direction. If the spacing needs to be adjusted or the clamp needs to be disassembled, simply rotate the adjusting threaded rod 15 to move the ratchet plate 14 inside the through groove 12, thereby disengaging the toothed end of the ratchet plate 14 from the limiting toothed plate 24. This achieves the dual functions of fastening and locking as well as flexible adjustment, ensuring that the clamp does not loosen during long-term use and improving the stability of cable protection.

[0021] For details, see Figure 1 The top end of the main clamp 1 is fixedly connected to a connecting post 21, and the other end of the connecting post 21 is fixedly connected to one end of the mounting plate 22. The connecting post 21 at the top of the main clamp 1 and the mounting plate 22 form an extended mounting structure. The connecting post 21 provides stable support for the mounting plate 22. The mounting plate 22 can be used to fix additional cable protection components (such as cable clamps, protective sleeves, warning signs, etc.) and can also be used to fix the main clamp 1.

[0022] Further, see Figures 2 to 4 One end of the U-shaped limiting groove 13 is connected to the bottom end of the main clamp 1, the size of the ratchet plate 14 matches the size of the through groove 12, the size of the U-shaped limiting block 16 matches the size of the U-shaped limiting groove 13, and it is slidably connected to its inner wall. One end of the U-shaped limiting groove 13 is connected to the bottom end of the main clamp 1, which facilitates the insertion of the U-shaped limiting block 16 of the auxiliary clamp 11 into the limiting groove from the bottom end, simplifying the installation operation; the ratchet plate 14 is the same size as the through groove 12, ensuring that there is no excess gap when the ratchet plate 14 slides in the through groove 12, avoiding the decrease in adjustment accuracy due to shaking, and ensuring that the driving force of the adjusting thread rod 15 can be transmitted to the auxiliary clamp 11; the U-shaped limiting block 16 is the same size as the U-shaped limiting groove 13 and is slidably connected. Its U-shaped structure can prevent the auxiliary clamp 11 from falling out of the limiting groove during the sliding process, and at the same time restrict the rotational freedom of the auxiliary clamp 11, ensuring that the auxiliary clamp 11 always remains parallel to the main clamp 1, so that the clamping force of the two on the tower members is evenly distributed, avoiding excessive local force that could cause clamp deformation or damage to the tower members.

[0023] It is worth noting that, see Figure 4 and Figure 5 The mounting hole 2 penetrates the interior of one end of the limiting tooth plate 24. One end of the limiting tooth plate 24 is rotatably connected to the inner wall of the built-in groove 17. The size of the built-in groove 17 matches the size of the limiting tooth plate 24. One end of the torsion spring 19 abuts against the outside of the fixed shaft 18, and the other end of the torsion spring 19 abuts against the inner wall of the mounting hole 2. Mounting hole 2 penetrates one end of limiting tooth plate 24, ensuring that limiting tooth plate 24 can be stably fitted onto fixed shaft 18, preventing it from shifting during rotation; one end of limiting tooth plate 24 is rotatably connected to the inner wall of built-in groove 17, the size of built-in groove 17 matches the size of limiting tooth plate 24, providing rotation space for limiting tooth plate 24 while limiting its lateral displacement, ensuring that the teeth of limiting tooth plate 24 can accurately mesh with ratchet plate 14; one end of torsion spring 19 abuts against fixed shaft 18, and the other end abuts against inner wall of mounting hole 2, the elastic torque of torsion spring 19 keeps limiting tooth plate 24 always tending to mesh with ratchet plate 14, even in vibration environment, it can quickly reset to achieve locking, preventing the clamp from loosening; at the same time, the wrapping design of built-in groove 17 can protect torsion spring 19 and fixed shaft 18, preventing them from being corroded by the external environment, extending the service life of locking structure, and ensuring long-term stable locking effect.
