Description
Technical Field
[0001] This utility model relates to the field of cable bending technology, specifically a small power cable bending device. Background Technology
[0002] In high-voltage power transmission systems, power cables are the key conductors responsible for current transmission in high-voltage and ultra-high-voltage transmission lines. Their typical structure consists of a high-strength steel core at the center, surrounded by multiple stranded aluminum wires. In this structure, the steel core plays a crucial reinforcing role, providing the necessary mechanical strength to withstand the enormous tension and environmental loads during line operation; while the outer aluminum wires are primarily responsible for conducting electrical energy, utilizing aluminum's excellent conductivity to achieve efficient transmission of high-voltage current.
[0003] Due to their high-strength steel core structure, power cables require end bending to change their direction when connected to electrical equipment. Current large cable bending tools are inconvenient to use at heights and in confined spaces. Improper force can easily damage the aluminum conductors or deform the steel core-aluminum layer structure, impairing conductivity and mechanical strength. Manual bending, on the other hand, is difficult to overcome the strength of the steel core, especially for thicker cables, as it is impossible to accurately form the required curvature, making it difficult to meet the stringent safety requirements of precise control.
[0004] To address this, we designed a dedicated electric power cable bending tool, aiming to solve the above problems simultaneously through mechatronics design, and achieve safe, efficient, non-destructive, and precise bending of high-strength composite cables in narrow, high-altitude environments.

Example 1
[0015] Please see Figure 1-4 This embodiment provides a small power cable bending device, including a main flange support plate 1, a bending rotating plate 3 rotatably mounted on the main flange support plate 1, a limiting bending wheel 2, an active bending wheel 4, and a driven bending wheel 5. The limiting bending wheel 2 is rotatably mounted on the main flange support plate 1, the active bending wheel 4 is rotatably mounted at the end of the bending rotating plate 3 away from the main flange support plate 1, and the driven bending wheel 5 is rotatably mounted at the rotation center of the bending rotating plate 3. Preferably, as a conventional design, in order to ensure the stability of the cable on the bending wheel, a groove 12 is provided on the bending wheel to prevent the cable from detaching from the bending wheel during bending. It should be noted that the specific positional relationship of the three bending wheels should be a technical solution that can be directly derived by those skilled in the art through the accompanying drawings of this application, and this application will not elaborate further.
[0016] A handle 9 and a drive assembly for driving the bending rotary plate 3 to reciprocate are also fixedly installed at the lower end of the main flange support plate 1.
[0017] Specifically, as a conventional drive structure familiar to those skilled in the art, the existing geared motor can be used to drive the bending and rotating plate 3. Preferably, in this application, the drive assembly includes a reducer 17 fixedly mounted at the lower end of the main flange support plate 1, with the output end of the reducer 17 fixedly connected to the bending and rotating plate 3, and a motor 15 fixedly mounted below the reducer 17, with the output end of the motor 15 fixedly connected to the input end of the reducer 17; it should be further noted that, as Figure 2As shown, as a standard configuration, a mounted bearing 16 is fixedly installed at the lower end of the reducer 17, and the motor 15 is fixedly installed at the lower end of the mounted bearing 16. The output end of the motor 15 passes through the mounted bearing 16 and connects to the input end of the reducer 17. Simultaneously, a dust cover 8 is fixedly installed at the lower end of the main flange support plate 1, covering the motor 15 and the reducer 17, to protect them. Furthermore, the selection of the motor 15 and the reducer 17 should be a conventional choice familiar to those skilled in the art. Preferably, the reducer 17 is a fully enclosed reducer, preferably a harmonic reducer. Its connection and assembly with the bending and rotating plate 3 is a conventional assembly method familiar to those skilled in the art, and will not be further elaborated upon.
[0018] Furthermore, such as Figure 1 , Figure 3 as well as Figure 4 As shown, two corresponding proximity switches 6 are provided on the upper end of the main flange support plate 1, and two sensing heads 14 corresponding to the proximity switches 6 are fixedly provided on the bending rotating plate 3. Simultaneously, a guide limiting groove 7 corresponding to the rotation trajectory of the bending rotating plate 3 is formed on the main flange support plate 1, and a guide slider 13 is fixedly provided at the lower end of the bending rotating plate 3. The guide slider 13 is slidably disposed in the guide limiting groove 7 to ensure the stability of the bending rotating plate 3 during rotation. Preferably, as... Figure 3 as well as Figure 4 As shown, the proximity switch 6 is located on both sides of the guide limiting groove 7, and the sensing head 14 is located on both sides of the guide slider 13. It should be noted that the selection of the models of the proximity switch 6 and the sensing head 14 should be a conventional selection familiar to those skilled in the art, and this application will not elaborate on any limitations.
[0019] like Figure 1 , Figure 2 as well as Figure 4 As shown, for operation, a main control board 18 and a battery are provided on the handle 9. Preferably, as is common practice for those skilled in the art, the main control board 18 and the battery are usually located at the bottom of the handle 9 for easy maintenance. Figure 2 As shown, a main control housing 10 is fixedly mounted at the bottom of the handle 9, and a main control board 18 is installed in the main control housing 10. A battery mounting bracket 19 is also provided at the bottom of the main control housing 10 for battery installation. The design of the main control board 18 and the battery mounting bracket 19 is merely a conventional preferred design. To increase battery volume, the battery can also be installed inside the handle 9, which should be a conventional arrangement familiar to those skilled in the art, and this application will not elaborate further.
[0020] Furthermore, such as Figure 1 as well as Figure 4As shown, a power button 11 is provided at the tail of the main flange support plate 1 to control the on / off state of the entire circuit. A motor control key 20 is also provided on the handle 9 to control the forward and reverse rotation of the motor 15, thereby realizing the rotation and reset of the bending rotating plate 3. It should be noted that the circuit connections in this bending device should be conventional designs familiar to those skilled in the art, and this application will not elaborate further.
[0021] In practical applications, by holding the handle 9 and turning on the power button 11 to power on the entire device, the cable is placed between the three bending wheels. By controlling the motor control key 20, the bending rotating plate 3 is rotated, which can drive the cable to bend. When the sensing head 14 at the bottom of the bending rotating plate 3 rotates above the proximity switch 6, the main control board 18 controls the motor 15 to stop running, and the bending rotating plate 3 stops rotating, thus achieving cable bending. Then, the cable is removed from the bending wheels, and the bending rotating plate 3 is reset by controlling the motor control key 20. In addition, as a conventional design familiar to those skilled in the art, the motor control key 20 should be a three-position control key used to control the start, stop, forward and reverse rotation of the motor. When the degree of cable bending is small and there is no need to bend the rotating plate 3 to rotate to the maximum angle, it is necessary to manually control the start and stop of the motor 15 by controlling the motor control key 20. This operation method should be a conventional operation familiar to those skilled in the art, and this application will not elaborate on the limitation.
[0022] Power workers can use this bending device in cable bending operations in compact spaces such as distribution cabinets and cable trays, which can effectively improve bending efficiency and reduce cable damage rate.
[0023] It should be noted that the above embodiments are only specific and clear descriptions of the technical solutions and features of this application.

[0024] Furthermore, the technical solutions of this application are not limited to the above embodiments. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
