Description

Technical Field

[0001] This invention belongs to the field of pipeline connection technology, and specifically relates to a high-voltage power pipe connection device for power transmission. Background Technology

[0002] In power transmission construction, high-voltage power pipes are required. When connecting multiple high-voltage power pipes, power pipe connection devices are needed, typically using heat fusion to connect the ends of two power pipes. However, existing power pipe connection devices have the following drawbacks:

[0003] 1. When using existing power pipe connection devices, the high-voltage pipes themselves accumulate a lot of dust during transportation. Since the existing connection devices do not have a cleaning mechanism, users will directly heat-melt the two high-voltage pipes together, which easily leads to breakage after connection.

[0004] 2. When using existing power pipe connection devices, the ports of the power pipes are exposed to the environment. During welding operations, dust from the construction site will directly fall onto the pipe ports. When the two power pipes are heat-fused together, the ports of the two pipes will contain a large amount of dust, which will easily lead to breakage.

[0005] 3. When using the existing power pipe connection device, the soldering plate and the connection device are designed separately. During use, the soldering plate needs to be moved from the support to the connection device. After the heat is melted, the soldering plate needs to be moved back to the support. This repeated movement can easily cause burns to others or damage to other parts, which is dangerous.

[0006] 4. When using existing power pipe connection devices, users need to use fixing mechanisms to fix a section of the pipe. However, the existing fixing mechanisms use multiple independent fixings. When fixing, users need to install 4 to 6 fixing components in sequence. This split design not only takes a long time to fix, but also the force applied by each fixing mechanism is not uniform, which can easily lead to pipe misalignment. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a high-voltage power pipe connection device for power transmission, which solves the technical problem that existing power pipe connection devices often result in breakage after connection due to dust generated during the transportation of high-voltage power pipes adhering to the ports of the high-voltage pipes themselves and directly heat-melting the two high-voltage pipes before cleaning.

[0008] The technical solution adopted by this invention to solve its technical problem is as follows: a high-voltage power pipe connection device for power transmission, comprising two docking platforms connected by a rotating shaft, with a pipe frame for accommodating the high-voltage power pipe slidably installed above each docking platform. Several threaded rods are installed side-by-side on the top of the pipe frame via a connecting plate. Some of the threaded rods are threadedly connected to the pipe frame, while the remaining threaded rods are slidably connected to the pipe frame. A clamping plate located inside the pipe frame is rotatably installed at the bottom end of the threaded rods. The clamping plates are used to fix the high-voltage power pipe inside the pipe frame. A main support is rotatably installed on the circumferential surface of the rotating shaft. An electric soldering plate for heat-melting the high-voltage power pipe is fixedly installed on the side end of the main support. An auxiliary support is installed at the upper end of the main support. Threaded sleeves are fixedly installed on both the left and right sides of the upper section of the auxiliary support. A first threaded pipe and a second threaded pipe are respectively threadedly installed inside the threaded sleeves. Positioning frames facing opposite directions are fixedly installed on the side ends of the first and second threaded pipes. Cleaning cotton for cleaning the high-voltage power pipe is installed through a side groove on the positioning frames.

[0009] The high-voltage power pipe connection device for power transmission includes a threaded rod comprising a first threaded rod and two second threaded rods mounted on a connecting plate. The first threaded rod is rotatably connected to the connecting plate, and the two second threaded rods are both connected to the connecting plate by threads. The first threaded rod is threadedly connected to the pipe support, and the second threaded rods are slidably connected to the pipe support.

[0010] The high-voltage power pipe connection device for power transmission has two collars fixedly installed on the circumferential surface of the first threaded rod, and the connecting plate is located between the two collars.

[0011] The high-voltage power pipe connection device for power transmission has side slots on the side ends of its positioning frame. Each of the two side slots is adapted to two threaded sleeves. Each side end of the positioning frame has a side groove. Multiple hexagonal cleaning cottons are fixedly installed on the inner wall of each side groove, including at least two first hexagonal cleaning cottons. At least two second hexagonal cleaning cottons and third hexagonal cleaning cottons of different sizes are fixedly installed on the side ends of each first hexagonal cleaning cotton. Each side groove is located on the side away from the first and second threaded pipes. The first hexagonal cleaning cottons are distributed in a ring on the inner wall of the side groove for cleaning the high-voltage power pipe.

[0012] The high-voltage power pipe connection device for power transmission has a support plate between two docking platforms that supports two positioning frames. The upper end of each support plate has an arc-shaped groove. An upper convex plate is fixedly installed at the upper end of the middle of the support plate. Two inverted T-shaped screws are movably installed at the upper end of the upper convex plate.

[0013] The high-voltage power pipe connection device for power transmission has two side supports fixedly installed between two docking platforms. Each side support has a heat insulation frame fixedly installed at its side end. A lower baffle is fixedly installed between the two heat insulation frames. The lower baffle is located at the bottom of the two heat insulation frames. The heat insulation frames and the lower baffle are used to support the soldering plate.

[0014] The high-voltage power pipe connection device for power transmission has four magnetic block support columns installed on its docking platform, and a sliding rod is installed on the side of the pipe frame through a side magnetic plate. The sliding rod passes through two magnetic block support columns arranged in front and behind.

[0015] The high-voltage power pipe connection device for power transmission has at least two rubber pads installed at the lower end of the clamping plate, and side inclined pads are fixedly installed on both the left and right sides of the lower end of each rubber pad; at least two rubber strips are fixedly installed on the inner wall of the bottom of the pipe rack, and multiple grooves are opened on the surface of each rubber strip, and a hollow groove is opened through the side end of each rubber strip.

[0016] The high-voltage power pipe connection device for power transmission has a telescopic pipe fixedly installed at the side end of the first threaded pipe, and a rotating plate fixedly installed on the surface of the telescopic pipe, with the rotating plate located in the U-shaped groove of the auxiliary support.

[0017] The high-voltage power pipe connection device for power transmission has a telescopic rod fixedly installed at the side end of the second threaded pipe, and the side end of the telescopic rod is slidably installed inside the first threaded pipe and the telescopic pipe.

[0018] The beneficial effects of this invention are as follows: When using this invention, two high-voltage power tubes can be attached to both sides of the soldering plate. After the two high-voltage power tubes have been heat-fused, they are then connected together. Subsequently, the heat-fusion device can be pulled out from the end of one of the tubes. By integrating the positioning frame and the soldering plate into one unit, the two high-voltage power tubes can be cleaned before connection, thereby reducing impurities at the ends of the two high-voltage power tubes. This effectively improves the success rate of heat-fusion connection of the two high-voltage power tubes and avoids breakage after welding due to excessive impurities at the ends of the high-voltage power tubes.

Implementation

[0029] The embodiments of this invention will be further described below with reference to specific examples and accompanying drawings.

[0030] The technical solution in this application embodiment effectively solves the technical problem that when using existing power pipe connection devices, the high-voltage pipes themselves will be covered with a lot of dust during transportation, and the existing connection devices do not have a cleaning mechanism. Users will directly heat-melt the two high-voltage pipes together, which is prone to breakage after connection. The overall idea is as follows.

[0031] Reference Figure 1 As shown, the present invention discloses a high-voltage power pipe connection device for power transmission, including two docking platforms 1. Each docking platform 1 is provided with a pulley assembly below it to facilitate the sliding of the docking platform 1. A rotating shaft 19 is fixedly installed between the two docking platforms 1. A pipe rack 2 for accommodating high-voltage power pipes 26 is slidably installed above each docking platform 1.

[0032] Reference Figure 2 , Figure 3 and Figure 5As shown, several threaded rods are installed side-by-side on the top of the pipe rack 2 via connecting plates 31. In this embodiment, preferably, one first threaded rod 3 and two second threaded rods 32 are installed on the three connecting plates 31. The first threaded rod 3 is rotatably connected to the three connecting plates 31, and the two second threaded rods 32 are both connected to the three connecting plates 31 by threads. The first threaded rod 3 is threadedly connected to the pipe rack 2, and each second threaded rod 32 is slidably connected to the pipe rack 2. Two collars 36 are fixedly installed on the circumferential surface of the first threaded rod 3, and the three connecting plates 31 are located between the two collars 36. The clamping plate 33 is designed to move synchronously, which allows users to quickly and easily fix the high-voltage power pipe 26, greatly improving the fixing speed and overall stability. The clamping plates 33 below the two second threaded rods 32 can also be independently adjusted, allowing for further position adjustment of the high-voltage power pipe 26. The lower ends of the first threaded rod 3 and the second threaded rod 32 are rotatably mounted with clamping plates 33, which are used to fix the high-voltage power pipe 26 inside the pipe rack 2. The two pipe racks 2 can be used to connect two high-voltage power pipes 26.

[0033] During use, each second threaded rod 32 can be rotated. Each second threaded rod 32 rotates within the three-plate 31 via threads. At this time, the second threaded rod 32 will drive the clamping plate 33 below to move up or down. By designing the three clamping plates 33 to move synchronously, it is convenient for users to quickly fix the high-voltage power pipe 26, greatly improving the fixing speed and the overall fixing integrity. Furthermore, the clamping plates 33 below the two second threaded rods 32 can be independently adjusted twice, thereby further adjusting the position of the high-voltage power pipe 26 and further improving the stability of the high-voltage power pipe 26 inside the pipe frame 2. This effectively improves the positional accuracy of the high-voltage power pipe 26 during welding, reduces the error of the connection between the two high-voltage power pipes 26, and further improves the welding accuracy. At the same time, the two pipe frames 2 are enclosed, which can effectively reduce the probability of dust entering from both sides of the high-voltage power pipe 26.

[0034] Reference Figure 6 , Figure 7 As shown, a main support 4 is rotatably mounted on the circumferential surface of the rotating shaft 19. A soldering plate 41 is fixedly mounted on the side end of the main support 4. The soldering plate 41 is used to heat melt the high-voltage power pipe 26. An auxiliary support 42 is fixedly mounted on the upper end of the main support 4. Threaded sleeves 43 are fixedly mounted on both the left and right sides of the upper section of the auxiliary support 42. A first threaded tube 44 and a second threaded tube 48 are respectively installed inside the two threaded sleeves 43 by threads. Positioning frames 45 are fixedly mounted on the side ends of the first threaded tube 44 and the second threaded tube 48, and the two positioning frames 45 face opposite directions. Cleaning cotton is installed on the two positioning frames 45 through the side groove 51 for cleaning the high-voltage power pipe 26.

[0035] By having the threads of the first threaded tube 44 and the second threaded tube 48 in opposite directions, the first threaded tube 44 and the second threaded tube 48 can move closer to each other. At the same time, the telescopic rod 49 and the telescopic tube 46 will be in a retracted state. When the first threaded tube 44 and the second threaded tube 48 rotate, they will drive the two positioning frames 45 to rotate. By using the rotating plate 47 to control the rotation and movement of the two positioning frames 45, the two high-voltage power pipes 26 can be wiped while being moved away from the two high-voltage power pipes 26, preparing for subsequent welding. At the same time, the rotating plate is located in the U-shaped groove of the auxiliary support 42, which can control the position between the two positioning frames 45, playing a good limiting role, thereby ensuring that the welding length of the two high-voltage power pipes 26 is the same.

[0036] Each of the two positioning frames 45 has a side slot 5 at its side end, and each of the two side slots 5 is adapted to two threaded sleeves 43. Each of the positioning frames 45 has a side groove 51 at its side end, and each side groove 51 has multiple hexagonal cleaning cottons fixedly installed on its inner wall.

[0037] Reference Figure 9 As shown, it includes at least two first hexagonal cleaning cottons 52, and at least two second hexagonal cleaning cottons 53 and third hexagonal cleaning cottons 54 of different sizes are fixedly installed on the side end of each first hexagonal cleaning cotton 52. Each side groove 51 is located on the side away from the first threaded tube 44 and the second threaded tube 48. The first hexagonal cleaning cottons 52 are arranged in a ring on the inner wall of the side groove 51 for cleaning the high-voltage power pipe 26. When the positioning frame 45 rotates, it will drive the multiple first hexagonal cleaning cottons 52, second hexagonal cleaning cottons 53 and third hexagonal cleaning cottons 54 to rotate synchronously. The first hexagonal cleaning cottons 52, second hexagonal cleaning cottons 53 and third hexagonal cleaning cottons 54 can effectively clean and wipe the port of the high-voltage power pipe 26, and the positioning frame 45 will gradually move away from the port of the high-voltage power pipe 26, thereby removing the dust in the port of the high-voltage power pipe 26. The cleaning ability is strong, improving the success rate of welding the high-voltage power pipe 26, and the two side grooves 51 can play a role in alignment. When the two high-voltage power pipes 26 come into contact with the two side grooves 51, their lengths are the same, and the user can observe the gap between the high-voltage power pipes 26 and the side grooves 51. This allows the user to determine whether there is a gap when the two high-voltage power pipes 26 are connected, thus effectively achieving a better position replication control function.

[0038] A support plate 12 is fixedly installed between the two docking platforms 1 located on the front side of the rotating shaft 19. The support plate 12 is used to support the two positioning frames 45. An upper convex plate 14 is fixedly installed at the upper end of the middle part of the support plate 12. An arc groove 13 is opened at the upper end of the support plate 12. Two inverted T-shaped screws 15 are movably installed at the upper end of the upper convex plate 14. An inverted T-shaped groove is provided inside the upper convex plate 14. The lower section of the T-shaped groove is a sliding groove, and the upper section of the T-shaped groove is a threaded section. The inverted T-shaped screws 15 are engaged with the upper convex plate 14 through threads. When the inverted T-shaped screws 15 move to the end of the T-shaped groove, they stop. When the rotating plate 47 is released, the main support 4 stops on the two inverted T-shaped screws 15 due to gravity.

[0039] Reference Figure 4 As shown, two side brackets 16 are fixedly installed between the two docking platforms 1 located on the rear side of the rotating shaft 19, and heat insulation brackets 17 are fixedly installed at the side ends of the two side brackets 16; a lower baffle 18 is fixedly installed between the two heat insulation brackets 17, and the lower baffle 18 is located at the bottom of the two heat insulation brackets 17. The heat insulation brackets 17 and the lower baffle 18 are used to support the soldering plate 41.

[0040] Four magnetic block support columns 11 are fixedly installed on the upper end of each of the two docking platforms 1. Two side magnetic plates 21 are fixedly installed on the side end of each pipe rack 2. A sliding rod 22 is fixedly installed between every two side magnetic plates 21. Each sliding rod 22 is slidably installed through the two front-to-back magnetic block support columns 11. In use, the two pipe racks 2 can be slid closer to each other. The sliding of the two pipe racks 2 causes the two high-voltage power pipes 26 to move closer to each other. When the ports of the two high-voltage power pipes 26 contact, the multiple side magnetic plates 21 just fit against the magnetic block support columns 11. At the same time, the side magnetic plates 21 and the magnetic block support columns 11 are magnetically attracted to each other. At this time, the two pipe racks 2 can remain stationary.

[0041] At least two rubber pads 34 are fixedly installed at the lower end of each clamping plate 33, and side inclined pads 35 are fixedly installed on the left and right sides of the lower end of each rubber pad 34. At least two rubber strips 23 are fixedly installed on the inner wall of the bottom of each pipe rack 2. Multiple grooves 25 are opened on the surface of each rubber strip 23. When multiple rubber strips 23 come into contact with the surface of the high-voltage power pipe 26, they will undergo a certain deformation, which can improve the friction between the rubber strips 23 and the high-voltage power pipe 26. A slot 24 is opened through the side end of each rubber strip 23, so the rubber strip 23 can undergo deformation at multiple angles, thereby improving the fit between the rubber strip 23 and the high-voltage power pipe 26 and further improving the stability of the high-voltage power pipe 26 inside the pipe rack 2.

[0042] The rubber pads 34 at the lower end of each clamping plate 33 will fit against the surface of the high-voltage power pipe 26. At the same time, the side-sloping pads 35 below each clamping plate 33 will play a good filling role, filling the gap between the high-voltage power pipe 26 and the pipe frame 2, further improving the stability of the high-voltage power pipe 26. Each clamping plate 33 plays a certain role as a bionic claw, improving the fixing ability of the high-voltage power pipe 26.

[0043] Reference Figure 8 As shown, a telescopic tube 46 is fixedly installed on the side end of the first threaded tube 44, and a rotating plate 47 is fixedly installed on the surface of the telescopic tube 46. The cross-sectional shape of the auxiliary support 42 is U-shaped, and the rotating plate 47 is located in the U-shaped groove of the auxiliary support 42. A telescopic rod 49 is fixedly installed on the side end of the second threaded tube 48, and the side end of the telescopic rod 49 is slidably installed in the first threaded tube 44 and the telescopic tube 46.

[0044] This invention integrates the positioning frame 45 and the soldering plate 41, allowing the two high-voltage power tubes 26 to be cleaned before connection. This reduces impurities at the ports of the two high-voltage power tubes 26, thereby effectively improving the success rate of the hot-melt connection of the two high-voltage power tubes 26 and reducing the phenomenon of breakage after welding due to excessive impurities at the ports of the high-voltage power tubes 26.

[0045] This invention patent effectively solves the problem that existing power pipe connection devices often suffer from dust accumulation at the ports of high-voltage power pipes during transportation. Since existing connection devices lack a cleaning mechanism, users often directly heat-melt the two high-voltage pipes, leading to breakage after connection. This invention integrates the positioning frame and soldering plate, allowing for pre-connection cleaning of the two high-voltage power pipes. This reduces impurities at the pipe ports, significantly improving the success rate of heat-melt connection and minimizing breakage caused by excessive impurities at the pipe ports.

[0046] The working principle of this invention is as follows.

[0047] The first step involves the user connecting two high-voltage power pipes 26. First, the two high-voltage power pipes 26 are inserted into the two pipe supports 2. The connection is stopped when the ends of the two pipe supports 2 contact the inner walls of the two positioning brackets 45. Then, the two top first threaded rods 3 are rotated. Each rotation of the first threaded rod 3 causes the three-plate 31 to move downwards. The downward movement of the three-plate 31 causes the two second threaded rods 32 to move downwards simultaneously. The connection is stopped when the three clamping plates 33 clamp the high-voltage power pipes 26. At this point, the user rotates the rotating plate 47. The rotation of the rotating plate 47, through the telescopic tube 46 and telescopic rod 49, causes the two positioning brackets 45 to rotate. The two positioning brackets 45 move while rotating and gradually move closer to each other. The rotation of the two positioning brackets 45 causes multiple first hexagonal cleaning cotton 52s to rotate. The rotation of the multiple first hexagonal cleaning cotton 52s cleans the inner and outer walls of the two high-voltage power pipes 26. When the two positioning brackets 45 disengage from the two high-voltage power pipes 26, the connection is closed. The user moves the rotating plate 47 downwards, causing the auxiliary support 42 to rotate. The auxiliary support 42 rotates outside the rotating shaft 19, suspending the soldering plate 41 and causing it to rotate upwards. The soldering plate 41 rotates upwards to the space between the two high-voltage power pipes 26. The user then slides the two pipe supports 2 to bring the two high-voltage power pipes 26 into contact with both sides of the soldering plate 41. After the two high-voltage power pipes 26 have been heat-fused, the user then connects them together. The heat-fused connection of the two high-voltage power pipes 26 is now complete. The user can then pull the device out from the end of one of the pipes. By integrating the positioning frame 45 and the soldering plate 41, the two high-voltage power pipes 26 can be cleaned before connection, reducing impurities at the ports of the two high-voltage power pipes 26. This effectively improves the success rate of the heat-fused connection of the two high-voltage power pipes 26 and reduces the phenomenon of breakage after welding due to excessive impurities at the ports of the high-voltage power pipes 26.

[0048] In the second step, when the two high-voltage power pipes 26 are inserted into the two pipe supports 2, the lower ends of the two pipe supports 2 will contact multiple rubber strips 23. Multiple grooves 25 are formed on the surface of the rubber strips 23. Therefore, when the rubber strips 23 contact the surface of the high-voltage power pipes 26, they will undergo a certain deformation, which increases the friction between the rubber strips 23 and the high-voltage power pipes 26. Simultaneously, each rubber strip 23 has an internal slot 24, allowing it to deform at multiple angles. This further improves the fit between the rubber strips 23 and the high-voltage power pipes 26, and further enhances the fit of the high-voltage power pipes 26 within the pipe supports 2. Internal stability: When the user rotates the first threaded rod 3, the first threaded rod 3 rotates inside the pipe frame 2 through the threads. At the same time, the first threaded rod 3 drives the three-link plate 31 to move downward through the two collars 36. The downward movement of the three-link plate 31 drives the two second threaded rods 32 to move downward synchronously. At this time, the three clamping plates 33 will simultaneously apply a downward pressure to the upper end of the high-voltage power pipe 26. The high-voltage power pipe 26 is clamped by multiple clamping plates 33 and rubber strips 23. When the high-voltage power pipe 26 is still not fixed stably, the user can rotate each second threaded rod 32. Each second threaded rod 32 is connected to the three-link plate 2 through the threads. When plate 31 rotates internally, the second threaded rod 32 drives the clamping plate 33 below to move upward or downward. By designing the three clamping plates 33 to move synchronously, users can quickly and easily fix the high-voltage power pipe 26, greatly improving the fixing speed and overall stability. Furthermore, the clamping plates 33 below the two second threaded rods 32 can be independently adjusted, allowing for further position adjustment of the high-voltage power pipe 26. This further improves the stability of the high-voltage power pipe 26 within the pipe rack 2, effectively enhancing the accuracy of the high-voltage power pipe 26's position during welding and reducing the risk of welding two high-voltage power pipes 26 together. The error is reduced, further improving the precision of welding. At the same time, the two pipe racks 2 are enclosed, which can effectively reduce the probability of dust entering from both sides of the high-voltage power pipe 26. When each clamping plate 33 contacts the high-voltage power pipe 26, the rubber pad 34 at the lower end of each clamping plate 33 will adhere to the surface of the high-voltage power pipe 26. At the same time, the side inclined pad 35 below each clamping plate 33 will play a good filling role, filling the gap between the high-voltage power pipe 26 and the pipe rack 2, further improving the stability of the high-voltage power pipe 26. Each clamping plate 33 plays a certain role as a bionic claw, improving the fixing ability of the high-voltage power pipe 26.

[0049] In the third step, when the ports of the two high-voltage power pipes 26 are inserted into the inner wall of the side groove 51 of the positioning frame 45, the ports of the high-voltage power pipes 26 will come into contact with a large number of first hexagonal cleaning cotton 52, second hexagonal cleaning cotton 53, and third hexagonal cleaning cotton 54. Each of the first hexagonal cleaning cotton 52, second hexagonal cleaning cotton 53, and third hexagonal cleaning cotton 54 is of different sizes and is arranged in a ring. At the same time, each of the first hexagonal cleaning cotton 52, second hexagonal cleaning cotton 53, and third hexagonal cleaning cotton 54 has a strong deformation capacity. Therefore, the multiple first hexagonal cleaning cotton 52, second hexagonal cleaning cotton 53, and third hexagonal cleaning cotton 54 can fully fit against the inner and outer walls of the ports of the high-voltage power pipes 26. When the positioning frame 45 rotates, it will drive the multiple first hexagonal cleaning cotton 52, second hexagonal cleaning cotton 53, and third hexagonal cleaning cotton 54 to come into contact with a large number of first hexagonal cleaning cotton 52, second hexagonal cleaning cotton 53, and third hexagonal cleaning cotton 54. The first hexagonal cleaning cotton 52, the second hexagonal cleaning cotton 53, and the third hexagonal cleaning cotton 54 rotate synchronously. They can effectively clean and wipe the port of the high-voltage power pipe 26. The positioning frame 45 will gradually move away from the port of the high-voltage power pipe 26, thereby removing the dust inside the port of the high-voltage power pipe 26. The cleaning ability is strong, which improves the success rate of welding the high-voltage power pipe 26. The two side grooves 51 can play a role in alignment. The two high-voltage power pipes 26 have the same length when they contact the two side grooves 51. The user can observe the gap between the high-voltage power pipe 26 and the side grooves 51, so as to determine whether there is a gap when the two high-voltage power pipes 26 are connected. This effectively plays a better role in position replication control.

[0050] When the user rotates the rotating plate 47, the rotation of the rotating plate 47 will drive the telescopic tube 46 to rotate, and the rotation of the telescopic tube 46 will drive the telescopic rod 49 to rotate. The rotation of the telescopic tube 46 and the telescopic rod 49 will respectively drive the first threaded tube 44 and the second threaded tube 48 to rotate. The first threaded tube 44 and the second threaded tube 48 rotate inside the two threaded sleeves 43 respectively. Because the threads of the first threaded tube 44 and the second threaded tube 48 are opposite in direction, they can move closer to each other. At the same time, the telescopic rod 49 and the telescopic tube 46 will be in a retracted state. The rotation of the first threaded tube 44 and the second threaded tube 48 will drive the two positioning frames 45 to rotate. By using the rotating plate 47 to control the rotation and movement of the two positioning frames 45, the two high-voltage power pipes 26 can be wiped while being moved away from the two high-voltage power pipes 26, preparing for subsequent welding. At the same time, the rotating plate 47 is located in the U-shaped groove of the auxiliary support 42, which can control the position between the two positioning frames 45, playing a good limiting role, thereby ensuring that the welding length of the two high-voltage power pipes 26 is the same. After the two telescopic tubes 46 are cleaned, the user moves the rotating plate 47 to rotate the main support 4. The rotation of the main support 4 causes the two positioning frames 45 to rotate. After the two positioning frames 45 rotate a certain angle, they will stop in the arc-shaped grooves 13 opened in the two support plates 12. At this time, the main support 4 drives the soldering plate 41 to rotate between the two high-voltage power pipes 26. After the welding is completed, the user lifts the main support 4 up a certain distance, pulls the two inverted T-shaped screws 15 up and rotates them. The inverted T-shaped screws 15 pass through the screw... The groove and the upper convex plate 14 cooperate. When the inverted T-shaped screw 15 moves to the end of the T-shaped groove, it stops. At this time, the rotating plate 47 is released, and the main support 4 stops on the two inverted T-shaped screws 15 under the force of gravity. At this time, the user can slide the two pipe racks 2 closer to each other. The sliding of the two pipe racks 2 drives the two high-voltage power pipes 26 to move closer to each other. When the ports of the two high-voltage power pipes 26 contact, the multiple side magnetic plates 21 just fit against the magnetic block support column 11. At the same time, the side magnetic plates 21 and the magnetic block support column 11 are magnetically attracted. At this time, the two pipe racks 2 can remain stationary.

[0051] By designing the main support 4 to rotate in three sections, the three steps of cleaning, heat fusion and butt welding can be achieved, integrating multiple steps into one operation, which greatly reduces the difficulty of welding.

[0052] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
