Description

Technical Field

[0001] This utility model relates to the field of lightning protection retrofit technology, and in particular to a welding device for lightning protection retrofit of power collection lines. Background Technology

[0002] A lightning rod, also known as a lightning arrestor or lightning rod, is a device used to protect buildings, tall trees, and other structures from lightning strikes. A lightning arrester is installed at the top of the protected object and connected to the underground grounding grid with a conductor of the appropriate specifications. In the lightning protection renovation project of power system collection lines, the on-site welding and installation of lightning rods is a key link in ensuring the lightning protection performance of the line.

[0003] Traditional welding operations often involve manual hand-held or simple clamps to fix lightning rods. Due to the lack of dedicated positioning and clamping devices, it is difficult for lightning rods to maintain precise posture and alignment. They are prone to displacement during the welding process due to thermal deformation or external disturbances, resulting in uneven welds, incomplete welds, or insufficient connection strength, which seriously affects the mechanical stability and electrical continuity of the lightning rod. Utility Model Content

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A welding device for lightning protection retrofitting of power collection lines, comprising: Two guide shafts, each with a fixing component installed at both ends, are arranged in parallel. The movable component is slidably mounted on two guide shafts, and a support shaft is rotatably mounted on the movable component. The drive mechanism, mounted on two fixed parts, is used to drive the support shaft to move and rotate. The mounting component is mounted on the support shaft via a connecting mechanism, and two clamping components are slidably mounted on the mounting component. The adjustment mechanism, installed on the mounting component, is used to drive the two clamping components to move synchronously in opposite directions.

[0006] Furthermore, the drive mechanism includes: Two worm gears are rotatably mounted on two fixed parts, with the axes of the two worm gears arranged in parallel and the axis of the worm gears being parallel to the axis of the guide shaft. The worm gear is coaxially mounted on the support shaft and meshes with two worms. Two drive motors are mounted on a fixed component, and the output ends of the two drive motors are respectively mounted coaxially with two worm gears.

[0007] Furthermore, when the drive motor starts: When the two worm gears rotate at the same speed and in the same direction, the support shaft is locked, causing the moving part to move along the axis of the guide shaft. When the two worm gears rotate in opposite directions at the same speed, the support shaft rotates, and the position of the moving part is locked.

[0008] Furthermore, the regulatory body includes: The threaded rod is rotatably mounted on the mounting piece. The threads at both ends of the threaded rod are opposite in direction. Two clamping pieces are respectively installed in thread engagement with both ends of the threaded rod. The power motor is mounted on the mounting bracket, and the output end of the power motor is connected to the threaded rod.

[0009] Furthermore, the connecting mechanism includes: The connecting shaft is coaxially and fixedly mounted on the support shaft. The mounting tube is fixedly installed on the mounting component. The mounting tube is plugged into and unplugged from the connecting shaft. The connecting shaft drives the mounting tube to rotate synchronously. Bolts are installed in the threaded through holes of the mounting tube and are used to lock the connection between the mounting tube and the connecting shaft.

[0010] Furthermore, the clamping component is provided with arc grooves, two arc grooves are arranged opposite each other, and the corners of the clamping component are chamfered.

[0011] Furthermore, the mounting component is equipped with a guide rail, and both clamping components are slidably connected to the guide rail.

[0012] Furthermore, the fastener is designed with an L-shaped structure and has assembly holes.

[0013] The following technical effects can be achieved through the technical solution of this utility model: Two parallel guide shafts form a stable installation base through fixed parts at both ends, providing sliding guidance for the moving parts and ensuring that the moving parts drive the support shaft to move smoothly. The support shaft moves and rotates under the drive mechanism, flexibly adjusting the position and angle of the lightning rods on the mounting parts and clamping parts to adapt to the welding position requirements of the lightning protection renovation of the power collection line, reducing the difficulty of operation. The mounting parts are mounted on the support shaft through the connecting mechanism, and the two clamping parts on it move synchronously in opposite directions under the drive of the adjustment mechanism, which can quickly clamp lightning rods of different specifications, ensuring that the lightning rods are stable and do not deviate during welding. The drive mechanism and the adjustment mechanism work together to improve welding efficiency and ensure the smooth progress of the lightning protection renovation operation.

[0018] This application provides a welding device for lightning protection retrofitting of power line, comprising: Two guide shafts 1 are provided, with fixing parts 2 installed at both ends, and the two guide shafts 1 are arranged in parallel. The movable part 3 is slidably mounted on two guide shafts 1, and a support shaft 4 is rotatably mounted on the movable part 3; The drive mechanism 5 is mounted on two fixed parts 2. The drive mechanism 5 is used to drive the support shaft 4 to move and rotate. Mounting component 6 is mounted on support shaft 4 via connecting mechanism 7. Two clamping components 8 are slidably mounted on mounting component 6. The two clamping components 8 are used to clamp and assist welding of lightning rod. Adjustment mechanism 9 is installed on mounting part 6. Adjustment mechanism 9 is used to drive the two clamping parts 8 to move synchronously in opposite directions. Through the technical solution of this utility model, two parallel guide shafts 1 form a stable installation base through the fixing parts 2 at both ends, providing sliding guidance for the moving part 3, ensuring that the moving part 3 drives the support shaft 4 to move smoothly. The support shaft 4 realizes displacement and rotation under the drive mechanism 5, flexibly adjusting the position and angle of the lightning rod on the mounting part 6 and the clamping part 8, adapting to the welding position requirements of the lightning protection transformation of the power collection line, reducing the difficulty of operation. The mounting part 6 is mounted on the support shaft 4 through the connecting mechanism 7, and the two clamping parts 8 on it move synchronously in opposite directions under the drive of the adjustment mechanism 9, which can quickly clamp lightning rods of different specifications, ensuring that the lightning rod is stable and does not deviate during welding. The drive mechanism 5 and the adjustment mechanism 9 work together to improve welding efficiency and ensure the smooth progress of the lightning protection transformation operation.

[0019] During use, the drive mechanism 5 includes: Two worm gears 51 are rotatably mounted on two fixed parts 2 respectively. The axes of the two worm gears 51 are parallel, and the axes of the worm gears 51 are parallel to the axis of the guide shaft 1. Worm gear 52 is coaxially mounted on support shaft 4, and worm gear 52 meshes with two worms 51. Two drive motors 53 are mounted on the fixing part 2, and the output ends of the two drive motors 53 are respectively coaxially mounted with the two worm gears 51. When drive motor 53 starts: When the two worm gears 51 are driven to rotate at the same speed and in the same direction, the support shaft 4 is locked in rotation, and the moving part 3 is driven to move along the axis of the guide shaft 1. When the two worm gears 51 rotate in opposite directions at the same speed, the support shaft 4 rotates and the position of the moving part 3 is locked. Through the technical solution of this utility model, two worm gears 51 are rotatably mounted on the fixed part 2 and mesh with the worm wheel 52 coaxially mounted on the support shaft 4. With the separate drive of the output ends of the two drive motors 53, the displacement and rotation of the support shaft 4 are provided. When the two drive motors 53 drive the worm gears 51 to rotate at the same speed and in the same direction, the worm wheel 52 is balanced by the same force, the support shaft 4 is locked in rotation, and only the moving part 3 is driven to move smoothly along the guide shaft 1 to realize the linear position adjustment of the lightning rod. When the two drive motors 53 drive the worm gears 51 to rotate in opposite directions at the same speed, the worm wheel 52 is driven to rotate by the opposite force, the position of the moving part 3 is locked, and the support shaft 4 drives the lightning rod to rotate to adjust the angle. Through the transmission method of the meshing of the worm gears 51 and the worm wheel 52, the transmission accuracy is high and it has self-locking property, ensuring that the position and angle of the lightning rod are stable and do not deviate after adjustment. The coordinated control of the two drive motors 53 makes the switching between displacement and rotation actions convenient and improves the flexibility of adapting to different welding positions.

[0020] As a preferred embodiment of the above, the adjusting mechanism 9 includes: The threaded rod 91 is rotatably mounted on the mounting part 6. The threads at both ends of the threaded rod 91 are opposite. The two clamping parts 8 are respectively installed in threaded engagement with both ends of the threaded rod 91. The power motor 92 is mounted on the mounting part 6, and the output end of the power motor 92 is connected to the threaded rod 91. Through the technical solution of this utility model, the threaded rod 91 is rotatably installed on the mounting part 6. Its two ends are designed with opposite screw directions. It is installed with two clamping parts 8 respectively with the threads at both ends of the threaded rod 91. When the threaded rod 91 rotates, it drives the two clamping parts 8 to move synchronously in the opposite direction without the need for separate adjustment. It is suitable for the clamping requirements of lightning rods of different diameters. The power motor 92 provides stable power to the threaded rod 91 to ensure that the clamping parts 8 move smoothly.

[0021] During use, the connecting mechanism 7 includes: The connecting shaft 71 is coaxially fixedly mounted on the support shaft 4; The mounting tube 72 is fixedly installed on the mounting part 6. The mounting tube 72 is inserted and removed from the connecting shaft 71. The connecting shaft 71 drives the mounting tube 72 to rotate synchronously. Bolt 73 is installed in the threaded through hole of the mounting tube 72, and bolt 73 is used to lock the connection position between the mounting tube 72 and the connecting shaft 71; Through the technical solution of this utility model, the connecting shaft 71 and the mounting tube 72 are plugged and unplugged for quick separation or assembly of the mounting component 6 and the support shaft 4. This facilitates the replacement of the appropriate clamping component 8 according to different types of lightning rods, improving the compatibility of the device with different specifications of lightning protection components. The connecting shaft 71 drives the mounting tube 72 to rotate synchronously, ensuring that when the support shaft 4 rotates to adjust the angle, the mounting component 6 and the clamped lightning rod rotate synchronously. After the mounting tube 72 and the connecting shaft 71 are assembled, the bolt 73 quickly locks the connection position of the two, preventing the mounting component 6 from loosening or shifting due to vibration during welding operations.

[0022] In the above embodiment, the clamping member 8 is provided with an arc groove, the two arc grooves are arranged opposite to each other, and the corners of the clamping member 8 are provided with chamfers. Through the technical solution of this utility model, the arc grooves arranged opposite to each other on the clamping member 8 fit tightly with the cylindrical shape of the lightning rod, increasing the clamping contact area and improving the clamping stability. The chamfer design at the corners of the clamping member 8 eliminates sharp edges.

[0023] As a preferred embodiment of the above, the mounting component 6 is provided with a guide rail 10, and both clamping components 8 are slidably connected to the guide rail 10. Through the technical solution of this utility model, the guide rail 10 provides sliding guidance for the two clamping parts 8, ensuring that the clamping parts 8 move synchronously in the opposite direction along the preset trajectory under the drive of the adjustment mechanism 9, thereby reducing the shaking of the clamping parts 8 when they move.
