Technical Field

[0001] This utility model relates to the field of power construction technology, specifically to a cable tensioning device used in power construction. Background Technology

[0002] During power construction, it is often necessary to tighten cables to prevent them from swaying or short circuits caused by contact between cables. When construction workers tighten cables on utility poles, it is usually done manually. Tightening cables at a height on utility poles is quite strenuous and carries certain risks.

[0003] A search revealed that patent document CN114389220B discloses a cable tensioning device for high-altitude power construction.

A positioning device is provided at the end of the rotating drum away from the winding wheel. A horizontal plate is provided above the winding wheel, with one bottom end of the horizontal plate fixedly connected to the top of the vertical plate. A fixed plate is fixedly connected to the bottom of the horizontal plate, and a rotating rod is hinged to the bottom end of the fixed plate via a pin. A locking block is fixedly connected to the bottom end of the rotating rod. A locking groove is circumferentially formed on the surface of the rotating drum, and the locking block corresponds to the locking groove. This invention can limit the movement of the winding wheel.

[0004] However, the above-mentioned issues still have the following drawbacks: For example, the durability and stability of the return spring are flawed; prolonged use or frequent operation may lead to spring fatigue, thus affecting its reset capability and stability. If the force design of the return spring is inappropriate, the locking block may fail to stably engage with the slot, or it may be too tight, causing operational difficulties.

[0023] 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.

[0024] Please see Figures 1 to 3 A cable tensioning device for power construction includes a cable tensioning structure for power construction consisting of a mounting base 2 and a winding wheel 4 mounted on the upper surface of a base frame 1. A mounting shaft 3 rotates on the mounting base 2, and a mounting sleeve 5, which is fixed to the mounting shaft 3, is fixed inside the winding wheel 4. Specifically, the mounting sleeve 5 is hollow inside and has through-holes at both ends. The mounting sleeve 5 is fixed to the mounting shaft 3 by bolts. The base frame 1 is L-shaped, and the mounting base 2 is bolted to the upper surface of the base frame 1.

[0025] In this embodiment, a locking structure 6 is provided at the right end of the take-up reel 4. The locking structure 6 includes a ratchet 601 disposed on the right side of the take-up reel 4, a connecting frame 602 rotatably mounted on the outer surface of the base frame 1, and a locking block 603 fixed to one side of the connecting frame 602 and used in conjunction with the ratchet 601. A limiting shaft 604 for limiting the connecting frame 602 is threadedly mounted on the outer surface of the base frame 1. The connecting frame 602 is rotatably mounted on the outer surface of the base frame 1. During the winding process, the ratchet 601 rotates with the take-up reel 4, while the locking block 603 is in an unlocked state, allowing the take-up reel 4 to rotate freely. When the cable reaches the required tension, the connecting frame 602 is limited by rotating the limiting shaft 604, causing the locking block 603 to contact and lock with the ratchet 601, preventing the take-up reel 4 from reversing, thereby maintaining the tension of the cable. The ratchet 601 is fixed to the right end of the mounting shaft 3.

[0026] To improve locking, the outer surface of the connecting frame 602 is provided with an elastic structure 7. The elastic structure 7 includes a telescopic sleeve 701 and a telescopic rod 702, a spring 705 fixed to the top of the telescopic rod 702, and a pressure adjusting component installed on the telescopic sleeve 701 for adjusting the pressure of the spring 705. A blocking sleeve 704 is threaded onto the top of the telescopic sleeve 701 to block the pressure adjusting component. The pressure adjusting component includes a mounting plate 706 fixed to the top side of the spring 705, a threaded sleeve 707 rotatably mounted on the upper surface of the telescopic sleeve 701, and a lifting screw 708 fixed to the upper surface of the mounting plate 706 and passing through the telescopic sleeve 701 and the threaded sleeve 707. The lifting screw 708 is threadedly connected to the threaded sleeve 707. The telescopic sleeve 701 is hollow inside. The degree of compression of the spring 705 determines the locking force of the connecting frame 602 on the ratchet 601. By precisely adjusting the compression of spring 705, the locking structure can provide a stable locking force under different operating conditions, preventing the cable from loosening or breaking due to external forces. The design of the elastic structure 7 allows the connecting bracket 602 to have a certain buffering and adaptability when subjected to external forces, thereby improving the stability and reliability of the entire locking structure.

[0027] To achieve rapid adjustment of the spring 705's compression, a driving component is mounted on the upper surface of the telescopic sleeve 701 to drive the rotation of the threaded sleeve 707. This driving component includes a motor 709 fixed to the upper surface of the telescopic sleeve 701, a transmission gear 710 fixed to the output shaft of the motor 709, and a driven gear 711 fixed to the outer surface of the threaded sleeve 707. Specifically, the transmission gear 710 meshes with the driven gear 711, and the transmission gear 710 and driven gear 711 are of different sizes. A connecting seat 703, hinged to the connecting frame 602, is fixed to the bottom end of the telescopic rod 702, and the top end of the telescopic sleeve 701 is hinged to the outer surface of the base frame 1. The motor 709 drives the transmission gear 710 to rotate, which in turn drives the driven gear 711 and the threaded sleeve 707 to rotate. Since the lifting screw 708 is threadedly connected to the threaded sleeve 707, the compression degree of the spring 705 can be quickly adjusted. This electric pressure adjustment method is faster and more precise than manual adjustment, greatly improving work efficiency. Rapid voltage adjustment means that the required locking force can be reached more quickly during cable tensioning, thus reducing adjustment time and labor costs. The outer surface of the telescopic sleeve 701 is also equipped with a spring-loaded observation window 705 for better operator control.

[0028] The working principle of the above embodiments is as follows:

[0029] First, fix the base frame 1 to the construction site to ensure stability. Then, install the mounting base 2 onto the upper surface of the base frame 1 using bolts. Next, fix the mounting sleeve 5 inside the take-up reel 4 to the mounting shaft 3 using bolts, thus completing the installation of the take-up reel 4. Then, wind the cable to be tightened onto the take-up reel 4 and begin the winding operation. During the winding process, the ratchet 601 rotates with the take-up reel 4, while the locking block 603 is in an unlocked state, allowing the take-up reel 4 to rotate freely. When the cable reaches the required tension, the connecting frame 602 is limited by rotating the limit shaft 604. The locking block 603 contacts and locks the ratchet 601 to prevent the winding wheel 4 from reversing, thereby maintaining the cable tension. According to actual needs, the position of the screw sleeve 707 is adjusted by the motor 709, transmission gear 710, and driven gear 711 on the drive component, thereby changing the compression degree of the spring 705. The compression degree of the spring 705 determines the locking force of the connecting bracket 602 on the ratchet 601, which in turn affects the cable tension holding ability. The shielding sleeve 704 is used to protect the voltage regulating component from external interference and also provides a certain degree of safety protection.

[0030] The installation method, connection method, or setting method disclosed in this embodiment are all common mechanical connections.

[0031] Any connection method that can achieve its beneficial effect can be implemented. In addition, all electrical components in this embodiment are electrically connected to the main controller and the power supply.

Moreover, the existing public power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
