Description

Technical Field

[0001] This utility model relates to the field of power transmission line technology, and in particular to a side phase conductor support device for power transmission line towers. Background Technology

[0002] Transmission lines and towers are indispensable components of the power system, playing a crucial role in power transmission. There are numerous types of transmission lines and towers, and this diversity is primarily to meet the requirements of different geographical environments, voltage levels, and economic costs.

[0003] Transmission lines cover a wide range of voltage levels, from low-voltage distribution networks to ultra-high-voltage and even extra-high-voltage transmission lines, with the highest voltage level reaching 1000 kV or even higher. The main advantage of high-voltage transmission is that it can reduce line losses and improve transmission efficiency, thereby enabling long-distance, large-capacity power transmission.

[0004] Transmission towers are crucial structures supporting power transmission lines, and they come in various types. Wooden towers are advantageous due to their low cost and ease of processing, but their durability is relatively poor, and they are typically used for low-voltage, short-distance transmission lines. Cement towers, on the other hand, offer high durability and stability at a moderate cost, and are widely used in medium- and low-voltage transmission lines. Steel frame towers and steel pipe towers, due to their high strength, corrosion resistance, and adaptability to complex terrain and high voltage levels, are the preferred choice for high-voltage and ultra-high-voltage transmission lines. For example, patent application CN222234395U discloses a side-phase conductor support device for transmission line towers, comprising a tower frame, a crossarm fixedly connected to the front surface of the tower frame, a reinforcing plate fixedly connected to the lower surface of the crossarm, a second support device fixedly connected to the lower surface of the crossarm, a first threaded sleeve provided on the outer surface of the second support device, and a second threaded sleeve threadedly connected to the outer surface of the first threaded sleeve. With the above structure, the device is equipped with a vertical adjustment device to raise the auxiliary support upwards to disperse the vertical force and prevent damage to the second support device due to excessive tension. To increase the tension of the first support device, a threaded rod is used to drive the slider to move back and forth, thereby tightening the first support device during the movement and achieving a stabilizing effect. However, the position and height of its fixed wire cannot be adjusted significantly, resulting in the brackets in different positions not being able to adjust the wire height significantly according to the terrain. Furthermore, the device may experience significant vibration and be unable to quickly reduce vibration during actual use. Utility Model Content

[0005] The purpose of this utility model is to overcome the defects of the prior art and provide a side phase conductor support device for transmission line towers, which enhances the adaptability and stability of the side phase conductor support device and improves the safety and reliability of transmission lines.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A side-phase conductor support device for transmission line towers includes a tower frame, symmetrical side arms fixedly connected to both sides of the tower frame, a conductor frame fixedly connected to the side arms, a rotating screw mounted on the conductor frame, and a lifting frame mounted on the rotating screw.

[0008] Furthermore, the side stretcher includes a stretcher, a reinforcing frame, and a support frame that are fixedly connected in sequence.

[0009] Furthermore, the stretcher is triangular in shape, and the top of the support frame is horizontally designed.

[0010] Furthermore, the wire frame includes a base plate, a shock absorber, and a frame. The base plate is fixedly connected to the top of the support frame, and the shock absorber is disposed between the base plate and the frame.

[0011] Furthermore, the rotating screw is mounted on the frame, and limit rods are provided on both sides of the rotating screw.

[0012] Furthermore, a sealing box is also provided on the frame, and a damper is provided inside the sealing box.

[0013] Furthermore, the damper is a spherical damper.

[0014] Furthermore, the lifting frame includes a slider and binding wheels, with the binding wheels disposed on the outer wall of the slider.

[0015] Furthermore, the slider is provided with a threaded groove, which matches the rotating screw.

[0016] Furthermore, the slider has limit holes on both sides of the threaded groove, and the limit holes match the limit rod.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This utility model includes symmetrical side arms fixedly connected to both sides of the tower, and wire frames fixedly connected to the side arms. A rotating screw and a limiting rod are set on the wire frames, and a lifting frame is set on the rotating screw. The binding wheels on the lifting frame are used to wind and fix the wires. The lifting frame can be raised and lowered on the rotating screw to achieve a large range of wire height adjustment, thereby enhancing the adaptability of the side phase wire support device.

[0019] 2. This utility model reduces vibration at the bottom of the frame by installing a shock absorber between the base plate and the frame, and reduces the vibration of the frame caused by wind by setting a damper in the sealed box. Since the frame is relatively high, the sealed box on the frame prevents the damper inside the sealed box from being blown away by airflow. This effectively reduces vibration caused by wind, terrain changes and other factors, enhances the stability of the side phase conductor support device, and improves the safety and reliability of the transmission line.

[0026] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. This embodiment is based on the technical solution of the present invention and provides detailed implementation methods and specific operating procedures; however, the scope of protection of the present invention is not limited to the following embodiments.

[0027] Example 1

[0028] This embodiment provides a side-phase conductor support device for transmission line towers, such as... Figure 1 As shown, it includes a tower 1, with symmetrical side arms 2 fixedly connected to both sides of the tower 1, a wire frame 3 fixedly connected to the side arms 2, a rotating screw 4 installed on the wire frame 3, and a lifting frame 5 installed on the rotating screw 4.

[0029] like Figure 2As shown, the side support 2 includes a stretcher 200, a reinforcing frame 201, and a support frame 202, which are fixedly connected in sequence. The stretcher 200, reinforcing frame 201, and support frame 202 are welded together. The stretcher 200 is triangular in shape. Due to its geometric characteristics, the triangular structure has a high resistance to deformation and can effectively distribute and bear the load from the conductor and the external environment. The reinforcing frame 201 further enhances the strength of the side support 2, ensuring that it will not deform or be damaged by external forces during long-term use. The top of the support frame 202 is horizontally designed, providing a stable platform for the installation of the wire frame 3, ensuring a firm and reliable connection between the wire frame 3 and the side support 2, thereby ensuring the structural stability of the entire support device.

[0030] like Figure 3 As shown, the wire frame 3 includes a base plate 300, shock absorbers 301, and a frame 302. The base plate 300 is fixedly connected to the top of the support frame 202. The frame 302 is a cuboid with a hollow design on its top and sides, which not only reduces the weight of the wire frame 3 but also provides space for the installation of components such as the rotating screw 4. Four shock absorbers 301 are installed between the base plate 300 and the frame 302. The four shock absorbers 301 are respectively located at the four corners of the bottom of the frame 302, which can effectively absorb the vibration of the wire frame 3 caused by wind and other factors, thereby protecting the structural stability of the wire frame 3 and the side support 2. A sealing box 303 is also provided on the frame 302, and a damper 304 is installed inside the sealing box 303. Figure 4 As shown, the damper 304 is a spherical damper, which can provide damping force when the conductor vibrates, further reducing the vibration amplitude, thereby extending the service life of the frame 302.

[0031] The rotating screw 4 is a key component for adjusting the height of the lifting frame 5. It is located in a hollowed-out area on one side of the frame 302, with a rotating handle on the top rotating disc for easy operation by power workers. By rotating the handle, the rotating screw 4 drives the lifting frame 5 to move up and down along its axis, thus achieving flexible height adjustment to meet the conductor installation requirements of transmission line towers in different terrains. Two limiting rods 6 on both sides of the rotating screw 4 match the limiting holes 502 on the lifting frame 5, effectively limiting the movement direction of the lifting frame 5, ensuring its smooth lifting and lowering along a predetermined trajectory, and preventing the slider 500 from shifting under vibration or external force, further improving the stability and reliability of the device.

[0032] like Figure 5As shown, the lifting frame 5 includes a slider 500 and a binding wheel 503. The binding wheel 503 is set on the outer wall of the slider 500 and is used to fix the conductor. The outer wall design of the binding wheel 503 facilitates the winding and fixing of the conductor, effectively preventing the conductor from loosening or falling off, thereby ensuring the safe operation of the transmission line. The slider 500 has a threaded groove 501, which matches the rotating screw 4, allowing the slider 500 to move up and down along its axis under the drive of the rotating screw 4, thereby realizing the height adjustment of the lifting frame 5 to adapt to the installation requirements of the conductors on the transmission line towers in different terrains. The slider 500 has limit holes 502 on both sides of the threaded groove 501, which match the limit rod 6. When the lifting frame 5 moves to the predetermined position, the limit holes 502 and the limit rod 6 cooperate to prevent the slider 500 from shifting under vibration or external force, ensuring the stability and reliability of the conductor support device.

[0033] The working principle and usage process of this utility model are as follows: After the side support 2 is installed and fixed on the tower 1, the wire frame 3 is installed and fixed on the support frame 202. The lifting frame 5 is installed on the rotating screw 4 and the limiting rod 6. Power workers can control the lifting of the lifting frame 5 by rotating the handle to rotate the rotating screw 4, and thus adjust the height of the lifting frame 5 according to environmental conditions (such as terrain changes, wind force, or conductor tension requirements). The shock absorber 301 installed between the base plate 300 and the frame 302 can provide shock absorption for the bottom of the frame 302. By setting a sealing box 303 on the frame 302, the airflow is prevented from blowing the damper 304 inside the sealing box 303. Since the frame 302 is relatively high, the damper 304 in the sealing box reduces the vibration of the frame 302 caused by wind. The outwardly extending side support 2 provides support for the installation of the wire frame 3, and the triangular support 200 ensures the stability of the side support 2. The reinforcing frame 201 ensures the strength of the side support 2. A horizontally designed support frame 202 is used to mount the base plate 300, thus ensuring the overall stability of the wire frame 3 and preventing tilting or instability from affecting the normal operation of the transmission line during power transmission. A threaded groove 501 on the slider 500 allows the rotating screw 4 to synchronously control the slider 500's lifting and lowering, thereby adjusting the height of the binding wheel 503 to accommodate conductor installation requirements at different heights. The limiting hole 502 and limiting rod 6 ensure the slider 500 remains stable during lifting and lowering, preventing deviation or swaying and ensuring the accurate movement trajectory of the lifting frame 5, thereby improving the reliability and safety of the device.

[0034] This invention, through a rational structural design, achieves stable support and flexible adjustment of the phase conductors on the side of transmission line towers, effectively reducing vibrations caused by factors such as wind and terrain changes, and improving the safety and reliability of transmission lines. Furthermore, the device is easy to install and adjust, meeting the needs of use in different environments, and possesses high practicality and application value.

[0035] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
