Description
Technical Field
[0001] This invention relates to the field of fire protection pipeline installation technology, specifically a pipeline laying device for fire protection engineering with a sealing detection function. Background Technology
[0002] In the field of fire protection engineering, piping systems are the core channels for transporting fire extinguishing media (such as water, foam, and gas), and their installation quality directly affects the reliability and effectiveness of the entire fire protection system. The sealing of pipe connections and the straightness of the pipe axis are two key indicators for measuring installation quality. Therefore, modern fire protection piping installation typically integrates multiple functions such as hoisting, connection, and sealing testing.
[0003] In current technical practices, pipeline laying typically employs cranes or gantry cranes in conjunction with simple lifting slings or wire ropes for hoisting and installation. However, this traditional method has several inherent drawbacks: When pipelines are lifted off the ground and moved in the air, they are prone to significant swaying and rotation due to factors such as wind force and the inertia of crane start-stop. This swaying not only poses a safety threat to operators and can easily lead to collisions with surrounding structures, damaging the anti-corrosion layer or sealing end face of the pipeline, but also greatly increases the difficulty of accurately aligning the bolt holes of the pipeline flange with those of the fixed pipeline flange, severely reducing construction efficiency.
[0004] Pipeline connections, especially those with flanges, require perfect alignment of the bolt holes on both flanges. Currently, this alignment process relies heavily on manual intervention. Operators must manually manipulate the heavy pipes with tools such as pry bars while the pipes are suspended in the air. This method is not only labor-intensive and carries extremely high safety risks, but also demands a high level of experience from workers, making it difficult to guarantee alignment accuracy and is time-consuming. This problem is particularly pronounced in confined or high-altitude working environments.
[0005] Most existing hoisting equipment has a single function, only responsible for transportation, and is disconnected from subsequent docking assistance and sealing inspection. Operators need to change tools and equipment multiple times to complete the entire process from hoisting to final inspection, which is cumbersome and has a low degree of automation. Summary of the Invention
[0006] The purpose of this invention is to provide a pipe laying device for fire protection engineering with a sealing detection function, so as to solve the problems mentioned in the prior art.
[0007] To achieve the above objectives, the present invention provides the following technical solution: The fire protection engineering pipe laying device with sealing detection function includes a mounting frame, an anti-sway unit, an alignment unit, and a hoisting unit. The mounting frame is placed on a horizontal ground. The anti-sway unit is fixedly connected to the mounting frame and has the function of preventing pipe swaying. The anti-sway unit is electrically connected to the alignment unit. The alignment unit is fixedly connected to the mounting frame, and the hoisting unit is fixedly connected to the mounting frame.
[0008] The mounting bracket is used to install and fix the anti-sway unit, alignment unit, and hoisting unit. The anti-sway unit is used to prevent the pipe from swaying during hoisting. The alignment unit is used to align the pipe at the installation position to improve installation efficiency. The hoisting unit is used for pipe transportation. During the transportation of the pipe through the hoisting unit, the anti-sway unit prevents the pipe from swaying during transportation. When the pipe is transported to the installation position, the alignment unit aligns the transported pipe with the already laid pipe, which facilitates the installation of fire protection pipes.
[0009] Furthermore, the anti-sway unit includes a buffer plate, a spring telescopic rod, a rotating ball, a telescopic plate, a push plate, and an elastic rod. One end of the buffer plate is fixedly connected to the telescopic end of the spring telescopic rod, and the fixed end of the spring telescopic rod is fixedly connected to the rotating ball. The rotating ball is rotatably mounted on the mounting frame. The telescopic end of the telescopic plate is fixedly connected to the telescopic end of the spring telescopic rod. The fixed end of the telescopic plate is slidably connected to the mounting frame via a straight rod. The telescopic plate is fixedly connected to the push plate via a straight rod. One end of the elastic rod is fixedly connected to the push plate. Wedge-shaped blocks are provided at both ends of the push plate. The buffer plate is in close contact with the outer wall of the pipe.
[0010] Furthermore, the anti-sway unit also includes a pull rod, a movable plate, a folding plate, a crossbar, a conductive block, and a conductive plate. One end of the pull rod is fixedly connected to an elastic rod, and the other end of the pull rod is fixedly connected to the movable plate. The movable plate is slidably mounted on the folding plate. A wedge block is provided at one end of the movable plate near the push plate. The other end of the elastic rod is fixedly connected to the folding plate. The folding plate is fixedly mounted on the mounting frame. Both ends of the crossbar are fixedly connected to the telescopic ends of the telescopic plate. The crossbar is fixedly connected to the conductive block through a straight rod. The conductive plate is installed below the conductive block and is fixedly mounted on the mounting frame. The wedge blocks of the push plate and the wedge blocks of the movable plate are in contact with each other.
[0011] During the downward transport of the pipeline, the buffer plate rotates downward around the rotating ball along with the spring telescopic rod, simultaneously causing the telescopic plate to extend downward. If the pipeline shakes and deflects to the left due to external forces during this period, the pipeline squeezes and pushes the buffer plate, causing the buffer plate to compress the spring telescopic rod for initial buffering. As the spring telescopic rod retracts, it moves to the left, which, under the transmission action of the telescopic plate, drives the push plate to move to the left and compress the elastic rod, causing the elastic rod to bend inward for anti-sway action. During the bending of the elastic rod, it pulls the tie rod, causing the moving plates to move closer to each other along the folded plate. The wedge-shaped block at the end of the moving plate further resists the push plate's leftward movement, thus achieving the anti-sway function of the pipeline.
[0012] Furthermore, the alignment unit includes an electric push rod, an electric telescopic rod, a fixed ring, an alignment ring, and conductive plates. The electric push rod is electrically connected to the conductive plate. The fixed end of the electric push rod is slidably mounted on the mounting frame via a straight rod. The output end of the electric push rod is fixedly connected to the outer surface of the alignment ring. The fixed end of the electric telescopic rod is fixedly mounted on the mounting frame. The telescopic end of the electric telescopic rod is fixedly connected to the alignment ring. The fixed ring consists of two semi-circular rings connected by an inner support spring. The fixed ring is initially in an open state. The alignment ring consists of two semi-circular rings connected by an inner support spring. The alignment ring is initially in an open state. The fixed ring is fixedly connected to the alignment ring. There are two conductive plates, both of which are fixedly mounted on the outer surface of the alignment ring.
[0013] Furthermore, the alignment unit also includes a support plate, a straight column, a drive coil, a pressing ring, an adjusting plate, and a telescopic motor. The support plate is fixedly connected to the straight column, the straight column is slidably mounted on the alignment ring, the drive coil is evenly wound on the straight column, the pressing ring is fixedly mounted on the outer end of the straight column located on the alignment ring, the adjusting plate is fixedly mounted on the telescopic end of the telescopic motor, the fixed end of the telescopic motor is fixedly mounted inside the alignment ring, and a conductive ring is provided at the contact end between the alignment ring and the straight column. The conductive plate on the left side is electrically connected to the telescopic motor, and the conductive plate on the right side is electrically connected to the conductive ring in the alignment ring.
[0014] As the controller extends the electric telescopic rod, driving the electric push rod to slide along the mounting bracket, the fixing ring and alignment ring descend synchronously with the pipe. As the pipe descends, the spring telescopic rod reaches the installation position, and the telescopic plate gradually extends, causing the crossbar to descend synchronously, bringing the conductive block into contact with the conductive plate below. At this point, the controller's current is transmitted to the electric push rod through the conductive block and conductive plate, causing the electric push rod to extend. This closes the fixing ring and alignment ring, forming a circular loop. Since the pipe to be installed is located at the support plate at this time, if the pipe to be installed is not aligned with the already installed pipe during the closure of the alignment ring, the offset part of the pipe to be installed will press against the support plate. Under the action of force, the support plate drives the straight column to move outward until the alignment ring is closed. At this time, the two conductive plates come into contact with each other. Since the conductive ring of the alignment ring is in contact with the straight column, the current of the drive coil is transmitted to the right conductive plate through the conductive ring, and then to the telescopic motor through the left conductive plate. The telescopic motor starts at this time. According to the length of the offset pipe pressing the straight column, the current transmitted by the drive coil is controlled, so that the telescopic motor at the corresponding position extends to the corresponding distance, driving the adjustment plate to press the offset pipe to be installed. After it is aligned with the installed pipe, the workers install the flange to connect the two pipes, thereby improving the pipe installation efficiency.
[0015] Furthermore, the hoisting unit includes a drive motor, a fixed platform, a rotating rod, a pull rope, and a lifting ring. The fixed end of the drive motor is fixedly mounted on the fixed platform, and the output end of the drive motor is fixedly connected to the rotating rod. The fixed platform is fixedly mounted on the mounting frame. One end of the pull rope is evenly wound around the rotating rod, and the pull rope is fixedly connected to the lifting ring, which is used to hoist the pipe.
[0016] After the workers place the lifting ring on the pipe, the controller starts the drive motor, which in turn rotates the rotating rod, causing the rope to gradually extend and move the pipe downward to the designated installation position.
[0017] Furthermore, the end of the drive coil closest to the tray is the current input terminal.
[0018] To make the offset pipe compress the straight column to move, the greater the offset, the longer the straight column moves. At this time, the fewer the effective turns of the drive coil, the lower the resistance, and the greater the current delivered to the telescopic motor. This allows the telescopic motor to extend a greater distance, correcting and aligning the pipe at the point of large offset, thereby improving pipe installation efficiency.
[0019] Furthermore, when the fixed ring is closed, its inner diameter is the same as the outer diameter of the pipe, and when the alignment ring is closed, its inner diameter is larger than the inner diameter of the fixed ring.
[0020] To ensure the retaining ring fits snugly against the pipe's outer diameter and increases stability, the inner diameter of the alignment ring is larger than the inner diameter of the retaining ring, which is also larger than the pipe's outer diameter, providing sufficient space for adjustment and correction of any misaligned pipe.
[0021] Furthermore, a temperature sensor is installed inside the alignment ring, which is used to detect the pipe's sealing performance.
[0022] After the pipes are aligned and installed, workers introduce hot air from the other end of the pipes. If the temperature sensor detects a temperature change, the pipe installation at that point is not properly sealed. If the temperature sensor does not detect a temperature change, the pipe installation at that point is properly sealed, thus completing the pipe sealing test.
[0023] Furthermore, the mounting bracket is equipped with a controller.
[0024] To facilitate automated control and timely feedback of the equipment, and to avoid slowing down construction efficiency due to untimely response.
[0025] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention achieves the anti-sway function of the pipeline by having a buffer plate rotate downwards along with the pipeline and a spring telescopic rod around a rotating ball during the downward transport of the pipeline. If the pipeline shakes and deflects to the left due to external forces during this period, the pipeline squeezes and pushes the buffer plate, which in turn squeezes the spring telescopic rod to contract, providing initial buffering. During the contraction of the spring telescopic rod, it moves to the left, thereby driving the push plate to move to the left under the transmission action of the telescopic plate, squeezing the elastic rod and causing it to bend inwards to prevent swaying. During the bending of the elastic rod, it pulls the tie rod, causing the moving plates to move closer to each other along the folded plate. The wedge-shaped block at the end of the moving plate further resists the leftward movement of the push plate.
[0026] 2. In this invention, the electric telescopic rod extends under the control of the controller, causing the electric push rod to slide along the mounting frame. During this process, the fixed ring and alignment ring descend synchronously with the pipe. As the pipe descends, the spring telescopic rod reaches the installation position. The telescopic plate gradually extends, causing the crossbar to descend synchronously, bringing the conductive block into contact with the conductive plate below. At this point, the controller's current is transmitted to the electric push rod through the conductive block and conductive plate, causing the electric push rod to extend. This closes the fixed ring and alignment ring, forming a circular loop. Since the pipe to be installed is located at the support plate at this time, if the pipe to be installed is not aligned with the already installed pipe during the closure of the alignment ring, the offset part of the pipe to be installed will squeeze the support plate. Under pressure, the support plate moves the straight column outward until the alignment ring closes. At this point, the two conductive plates come into contact with each other. Since the conductive ring of the alignment ring is in contact with the straight column, the current of the drive coil is transmitted through the conductive ring to the right conductive plate, and then through the left conductive plate to the telescopic motor. The telescopic motor starts and controls the current transmitted by the drive coil according to the distance the offset pipe squeezes the straight column, so that the telescopic motor at the corresponding position extends to the corresponding distance, driving the adjustment plate to squeeze the offset pipe to be installed. After aligning with the installed pipe, the workers install the flange to connect the two pipes, thereby improving the efficiency of pipe installation.
[0027] 3. After the pipes are aligned and installed, the operator introduces hot air from the other end of the pipe. If the temperature sensor detects a temperature change, the pipe installation at that point is not properly sealed. If the temperature sensor does not detect a temperature change, the pipe installation at that point is properly sealed, thus achieving the pipe sealing test. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0031] Example: Figures 1-8 As shown, the present invention provides a technical solution: like Figure 1 As shown, a fire protection engineering pipe laying device with a sealing detection function includes a mounting frame 1, an anti-sway unit 2, an alignment unit 3, and a hoisting unit 4. The mounting frame 1 is placed on a horizontal ground. The anti-sway unit 2 is fixedly connected to the mounting frame 1 and has the function of preventing pipe swaying. The anti-sway unit 2 is electrically connected to the alignment unit 3. The alignment unit 3 is fixedly connected to the mounting frame 1. The hoisting unit 4 is fixedly connected to the mounting frame 1.
[0032] Mounting bracket 1 is used to install and fix anti-sway unit 2, alignment unit 3 and hoisting unit 4. Anti-sway unit is used to prevent the pipeline from swaying during hoisting. Alignment unit 3 is used to align the pipeline at the installation position to improve installation efficiency. Hoisting unit 4 is used for pipeline transportation. During the transportation of pipeline through hoisting unit 4, anti-sway unit 2 prevents the pipeline from swaying during transportation. When the pipeline is transported to the installation position, alignment unit 3 aligns the transported pipeline with the already laid pipeline to facilitate the installation of fire protection pipeline.
[0033] like Figure 4 , Figure 5 As shown, the anti-sway unit 2 includes a buffer plate 21, a spring telescopic rod 22, a rotating ball 23, a telescopic plate 24, a push plate 25, and an elastic rod 26. One end of the buffer plate 21 is fixedly connected to the telescopic end of the spring telescopic rod 22, and the fixed end of the spring telescopic rod 22 is fixedly connected to the rotating ball 23. The rotating ball 23 is rotatably mounted on the mounting frame 1. The telescopic end of the telescopic plate 24 is fixedly connected to the telescopic end of the spring telescopic rod 22. The fixed end of the telescopic plate 24 is slidably connected to the mounting frame 1 through a straight rod. The telescopic plate 24 is fixedly connected to the push plate 25 through a straight rod. One end of the elastic rod 26 is fixedly connected to the push plate 25. Wedge-shaped blocks are provided at both ends of the push plate 25. The buffer plate 21 is in close contact with the outer wall of the pipe.
[0034] like Figure 4 , Figure 5 As shown, the anti-sway unit 2 also includes a pull rod 27, a movable plate 28, a folding plate 29, a crossbar 210, a conductive block 211, and a conductive plate 212. One end of the pull rod 27 is fixedly connected to the elastic rod 26, and the other end of the pull rod 27 is fixedly connected to the movable plate 28. The movable plate 28 is slidably mounted on the folding plate 29. A wedge block is provided at one end of the movable plate 28 near the push plate 25. The other end of the elastic rod 26 is fixedly connected to the folding plate 29. The folding plate 29 is fixedly mounted on the mounting frame 1. Both ends of the crossbar 210 are fixedly connected to the telescopic ends of the telescopic plate 24. The crossbar 210 is fixedly connected to the conductive block 211 through a straight rod. The conductive plate 212 is installed below the conductive block 211 and is fixedly mounted on the mounting frame 1. The wedge block of the push plate 25 and the inclined surface of the wedge block of the movable plate 28 are in contact with each other.
[0035] During the downward transport of the pipeline, the buffer plate 21 rotates downward around the rotating ball 23 along with the spring telescopic rod 22, while simultaneously extending the telescopic plate 24 downward. If the pipeline shakes and deflects to the left due to external forces during this period, the pipeline squeezes and pushes the buffer plate 21, causing the buffer plate 21 to compress the spring telescopic rod 22 for initial buffering. As the spring telescopic rod 22 retracts, it moves to the left, thereby driving the push plate 25 to move to the left and compress the elastic rod 26 under the transmission action of the telescopic plate 24. This causes the elastic rod 26 to bend inward for anti-sway action. During the bending process, the elastic rod 26 pulls the pull rod 27, causing the moving plate 28 to move closer to each other along the folding plate 29. The wedge-shaped block at the end of the moving plate 28 further resists the leftward movement of the push plate 25, thus realizing the anti-sway function of the pipeline.
[0036] like Figure 2 , Figure 3 , Figure 6 As shown, the alignment unit 3 includes an electric push rod 31, an electric telescopic rod 32, a fixed ring 33, an alignment ring 34, and conductive plates 35. The electric push rod 31 is electrically connected to the conductive plate 212. The fixed end of the electric push rod 31 is slidably mounted on the mounting frame 1 via a straight rod. The output end of the electric push rod 31 is fixedly connected to the outer surface of the alignment ring 34. The fixed end of the electric telescopic rod 32 is fixedly mounted on the mounting frame 1. The telescopic end of the electric telescopic rod 32 is fixedly connected to the alignment ring 34. The fixed ring 33 consists of two semi-circular rings connected by an inner support spring. The fixed ring 33 is initially in an open state. The alignment ring 34 consists of two semi-circular rings connected by an inner support spring. The alignment ring 34 is initially in an open state. The fixed ring 33 and the alignment ring 34 are fixedly connected. There are two conductive plates 35, which are fixedly mounted on the outer surface of the alignment ring 34.
[0037] like Figure 7 , Figure 8 As shown, the alignment unit 3 also includes a support plate 36, a straight column 37, a drive coil 38, a pressing ring 39, an adjusting plate 310, and a telescopic motor 311. The support plate 36 is fixedly connected to the straight column 37, and the straight column 37 is slidably mounted on the alignment ring 34. The drive coil 38 is evenly wound on the straight column 37. The pressing ring 39 is fixedly mounted on the end of the straight column 37 located outside the alignment ring 34. The adjusting plate 310 is fixedly mounted on the telescopic end of the telescopic motor 311. The fixed end of the telescopic motor 311 is fixedly mounted inside the alignment ring 34. A conductive ring is provided at the contact end between the alignment ring 34 and the straight column 37. The left conductive piece 35 is electrically connected to the telescopic motor 311, and the right conductive piece 35 is electrically connected to the conductive ring in the alignment ring 34.
[0038] As the controller controls the extension of the electric telescopic rod 32, driving the electric push rod 31 to slide along the mounting bracket 1, the fixing ring 33 and the alignment ring 34 descend synchronously with the pipe. As the pipe descends, the spring telescopic rod 22 descends to the installation position, and the telescopic plate 24 gradually extends, causing the crossbar 210 to descend synchronously, bringing the conductive block 211 into contact with the lower conductive plate 212. At this time, the controller's current is transmitted to the electric push rod 31 through the conductive block 211 and the conductive plate 212, causing the electric push rod 31 to extend. This closes the fixing ring 33 and the alignment ring 34, forming a ring. Since the pipe to be installed is located at the support plate 36 at this time, if the pipe to be installed is not aligned with the already installed pipe during the closing of the alignment ring 34, the offset part of the pipe to be installed will press against the support plate 36. 6. Under pressure, the support plate 36 drives the straight column 37 to move outward until the alignment ring 34 is closed. At this time, the two conductive plates 35 are in contact with each other. Since the conductive ring of the alignment ring 34 is in contact with the straight column 37, the current of the drive coil 38 is transmitted to the right conductive plate 35 through the conductive ring, and then to the telescopic motor 311 through the left conductive plate 35. At this time, the telescopic motor 311 starts. According to the distance of the offset pipe pressing the straight column 37, the current transmitted by the drive coil 38 is controlled, so that the telescopic motor 311 at the corresponding position extends to the corresponding distance, driving the adjustment plate 310 to press the offset pipe to be installed. After aligning with the installed pipe, the staff will install the flange to connect the two pipes, thereby improving the pipe installation efficiency.
[0039] like Figure 2 As shown, the hoisting unit 4 includes a drive motor 41, a fixed platform 42, a rotating rod 43, a pull rope 44, and a lifting ring 45. The fixed end of the drive motor 41 is fixedly installed on the fixed platform 42, and the output end of the drive motor 41 is fixedly connected to the rotating rod 43. The fixed platform 42 is fixedly installed on the mounting frame 1. One end of the pull rope 44 is evenly wound around the rotating rod 43, and the pull rope 44 is fixedly connected to the lifting ring 45. The lifting ring 45 is used to hoist the pipe.
[0040] After the workers put the lifting ring 45 on the pipe, the controller starts the drive motor 41, which drives the rotating rod 43 to rotate, causing the pull rope 44 to gradually extend and move the pipe downward to the designated installation position.
[0041] like Figure 8 As shown, the end of the drive coil 38 closest to the support plate 36 is the current input terminal.
[0042] In order to make the offset pipe squeeze the straight column 37 move, the greater the offset, the more distance the straight column 37 moves. At this time, the number of effective turns of the drive coil 38 is less, the resistance is smaller, and the current delivered to the telescopic motor 311 is greater. This allows the telescopic motor 311 to extend a greater distance, correct and align the pipe at the point of large offset, thereby improving the efficiency of pipe installation.
[0043] like Figure 6 As shown, when the fixed ring 33 is closed, its inner diameter is the same as the outer diameter of the pipe, and when the alignment ring 34 is closed, its inner diameter is larger than the inner diameter of the fixed ring 33.
[0044] In order to make the fixing ring 33 fit tightly against the outer diameter of the pipe and increase stability, the inner diameter of the alignment ring 34 is larger than the inner diameter of the fixing ring 33, which is also larger than the outer diameter of the pipe, so as to provide enough space for the offset pipe to be adjusted and corrected.
[0045] like Figure 6 As shown, a temperature sensor is installed inside the alignment ring 34, which is used to detect the pipe's sealing performance.
[0046] After the pipes are aligned and installed, workers introduce hot air from the other end of the pipes. If the temperature sensor detects a temperature change, the pipe installation at that point is not properly sealed. If the temperature sensor does not detect a temperature change, the pipe installation at that point is properly sealed, thus completing the pipe sealing test.
[0047] like Figure 1 As shown, mounting bracket 1 is equipped with a controller.
[0048] To facilitate automated control and timely feedback of the equipment, and to avoid slowing down construction efficiency due to untimely response.
[0049] Working principle of the invention: After the workers put the lifting ring 45 on the pipe, the controller starts the drive motor 41, which drives the rotating rod 43 to rotate, causing the pull rope 44 to gradually extend and move the pipe downward to the designated installation position.
[0050] During the downward transport of the pipeline, the buffer plate 21 rotates downward around the rotating ball 23 along with the spring telescopic rod 22, while simultaneously extending the telescopic plate 24 downward. If the pipeline shakes and deflects to the left due to external forces during this period, the pipeline squeezes and pushes the buffer plate 21, causing the buffer plate 21 to compress the spring telescopic rod 22 for initial buffering. As the spring telescopic rod 22 retracts, it moves to the left, thereby driving the push plate 25 to move to the left and compress the elastic rod 26 under the transmission action of the telescopic plate 24. This causes the elastic rod 26 to bend inward for anti-sway action. During the bending process, the elastic rod 26 pulls the pull rod 27, causing the moving plate 28 to move closer to each other along the folding plate 29. The wedge-shaped block at the end of the moving plate 28 further resists the leftward movement of the push plate 25, thus realizing the anti-sway function of the pipeline.
[0051] As the controller controls the extension of the electric telescopic rod 32, driving the electric push rod 31 to slide along the mounting bracket 1, the fixing ring 33 and the alignment ring 34 descend synchronously with the pipe. As the pipe descends, the spring telescopic rod 22 descends to the installation position, and the telescopic plate 24 gradually extends, causing the crossbar 210 to descend synchronously, bringing the conductive block 211 into contact with the lower conductive plate 212. At this time, the controller's current is transmitted to the electric push rod 31 through the conductive block 211 and the conductive plate 212, causing the electric push rod 31 to extend. This closes the fixing ring 33 and the alignment ring 34, forming a ring. Since the pipe to be installed is located at the support plate 36 at this time, if the pipe to be installed is not aligned with the already installed pipe during the closing of the alignment ring 34, the offset part of the pipe to be installed will press against the support plate 36. 6. Under pressure, the support plate 36 drives the straight column 37 to move outward until the alignment ring 34 is closed. At this time, the two conductive plates 35 are in contact with each other. Since the conductive ring of the alignment ring 34 is in contact with the straight column 37, the current of the drive coil 38 is transmitted to the right conductive plate 35 through the conductive ring, and then to the telescopic motor 311 through the left conductive plate 35. At this time, the telescopic motor 311 starts. According to the distance of the offset pipe pressing the straight column 37, the current transmitted by the drive coil 38 is controlled, so that the telescopic motor 311 at the corresponding position extends to the corresponding distance, driving the adjustment plate 310 to press the offset pipe to be installed. After aligning with the installed pipe, the staff will install the flange to connect the two pipes, thereby improving the pipe installation efficiency.
