Description

Technical Field

[0001] This invention belongs to the field of pipeline installation technology, and more specifically, relates to a pipeline installation device and its use and recycling method. Background Technology

[0002] In building electromechanical installation projects, piping systems for water supply and drainage, HVAC, and fire protection are often centrally located on integrated supports, forming multi-layered, multi-row spatial pipeline layouts. As pipe diameters and the number of pipe layers increase, the difficulty of installing high-altitude pipelines rises significantly. Traditional construction methods often involve setting up hoists under the high-altitude floor slab to lift each pipe to the installation height, then manually pulling and adjusting its position using pry bars. This method is not only cumbersome and inefficient, but also, in multi-layered pipeline environments, when the pipe to be installed is above or inside existing pipelines, the lifting path is often obstructed by the existing pipelines, requiring repeated disassembly and reassembly of lifting equipment or temporary removal of existing pipes, severely delaying the construction period. Furthermore, large-diameter pipes are heavy and installed at great heights, posing a significant risk of fall for workers operating at heights for extended periods. Although some existing technologies have proposed solutions for lifting pipelines using jacking mechanisms, most of them can only achieve vertical jacking in place and cannot flexibly adjust the position in the horizontal direction. Furthermore, they cannot achieve obstacle avoidance and horizontal movement across interfering pipelines in multi-layered pipe corridors, making it difficult to meet the installation requirements of pipelines in complex spaces under integrated support and hanger scenarios. Summary of the Invention

[0003] To address the aforementioned deficiencies or improvement needs of existing technologies, this invention provides a pipe installation device, comprising: a lifting base, serving as a base and performing a vertical lifting action; a translational seat, disposed at the top of the lifting base; an obstacle avoidance frame, disposed on the translational seat, wherein the lateral lifting device and the central lifting device of the obstacle avoidance frame can be raised relative to the translational seat to pass over interfering pipes during translation and then reset; and a support assembly, disposed on the obstacle avoidance frame, on which a pipe placement frame is provided for placing the pipe to be lifted and installed.

[0004] In one embodiment of the present invention, the lifting base includes: a base plate; base wheels disposed at the bottom of the base plate; a lifting frame disposed at the top of the base plate; and a lifting power device disposed on one side of the base plate, the power output end of which is rotatably connected to the lifting frame and provides power for the lifting action of the lifting frame.

[0005] In one embodiment of the present invention, the translation base includes: a plate frame, rotatably connected to the top of the lifting frame, the plate frame being a hollow U-shaped structure; a translation device, disposed in the hollow structure inside the plate frame and fixedly connected to the plate frame; and a follower plate, fixedly connected to the upper surface of the translation device and capable of moving with the translation device.

[0006] In one embodiment of the present invention, the obstacle avoidance frame includes: a lateral lifting device, the bottom end of which is movably abutted against the follower plate, and the top end of which is rotatably connected to a lifting mounting plate via a bidirectional hinge; a central lifting device, the bottom end of which is movably abutted against the follower plate, and the top end of which is rotatably connected to the lifting mounting plate via a bidirectional hinge; and a fixed lifting device, the bottom end of which is fixedly connected to the follower plate, and the top end of which is rotatably connected to the lifting mounting plate via a unidirectional hinge.

[0007] In one embodiment of the present invention, the support assembly further includes: a support frame, fixedly connected to the lifting mounting plate, on which a downward pressing power device is fixedly disposed, and a downward pressing rod is fixedly connected to the power output end of the downward pressing power device; and a support wing arm, including a vertical positioning rod, a first wing arm, a second wing arm, and a follower positioning rod, wherein: the vertical positioning rod is rotatably connected to the first wing arm and the second wing arm, and forms a parallelogram structure with the follower positioning rod, while the vertical positioning rod is fixedly connected to the downward pressing rod; the first wing arm and the second wing arm are rotatably connected to the support frame, so that the follower positioning rod and the vertical positioning rod always remain parallel, and the tube placement frame is fixedly disposed on the outer side of the follower positioning rod.

[0008] In one embodiment of the present invention, the support assembly further includes a sliding wing arm assembly, the structure of which includes: a first sliding wing arm, one end of which is slidably disposed on the upper surface of the first wing arm via a sleeve ring, and the other end of which is rotatably connected to a sliding guide arm and a follower mounting arm; a second sliding wing arm, one end of which is rotatably connected to the follower positioning rod, and the other end of which is rotatably connected to the sliding guide arm and the follower mounting arm, wherein the follower mounting arm, the second sliding wing arm, the first sliding wing arm, and the follower positioning rod form a parallelogram structure, so that the follower mounting arm and the follower positioning rod always remain parallel; a sliding power device, fixedly disposed at the lower end of the first wing arm, the power output end of which is rotatably connected to the sliding guide arm, and provides power for the movement of the first sliding wing arm and the second sliding wing arm through the sliding guide arm; the follower mounting arm is also provided with the tube placement frame.

[0009] In one embodiment of the present invention, the supporting wing arm and the follow-up positioning rod further include a clamping and fixing device, and the outer side of the pipe placement frame is provided with a fixing hole. The two are fixed to the pipe placed on the pipe placement frame by the fixing cable on the clamping and fixing device.

[0010] In one embodiment of the present invention, the clamping and fixing device includes: a housing, fixedly disposed on the supporting wing arm and the follower positioning rod; a pair of movable clamps, rotatably disposed on the inner side of the housing; a clamping power device, disposed on the inner side of the movable clamps and providing power for the opening action of the movable clamps; and a rigid cable head, fixedly connected to one end of the fixing cable, having an annular groove thereon that cooperates with the movable clamps, wherein the other end of the fixing cable is fixedly connected to the fixing hole.

[0011] In one embodiment of the present invention, the obstacle avoidance frame further includes a lifting pad, which is fixedly disposed at the bottom end of the lateral lifting device and the central lifting device.

[0012] The present invention also provides a method for using and recycling a pipeline installation device, the steps of which are as follows: Place the pipe to be installed on the pipe rack, insert the rigid cable head into the movable clamp and lock it; Move the lifting base to a position below the installation location, and use the lifting base to lift the pipe to the initial target height; Move the obstacle avoidance frame to one side of the interference pipe, and translate the translation seat so that the lateral lifting device and the central lifting device are lifted during the translation process, allowing the interference pipe to enter the space between it and the fixed lifting device until the lifting mounting plate is set above the interference pipe. Then, reset the lateral lifting device and the central lifting device. The pipe position is finely adjusted by the supporting wing arm and sliding wing arm assembly to align it and place it in the designed installation position, thus completing the installation. After installation, open the movable clamp, drive the supporting wing arm and sliding wing arm assembly to retract, so that the rigid cable head comes out and releases the fixation on the pipe; The obstacle avoidance frame is moved out from above the interference pipe, and then the entire device is moved out to complete the recovery.

[0013] In summary, compared with the prior art, the above-described technical solutions conceived by this invention can achieve the following beneficial effects: This invention, by incorporating a lateral lifting device and a central lifting device that can be raised and reset relative to the translational seat, enables the obstacle avoidance frame to actively or passively traverse installed interfering pipes during translation, achieving barrier-free horizontal pipe movement in multi-layer integrated support environments. The pipe to be installed can be delivered to the designated location without disassembling existing pipes. Through three-stage motion decoupling—vertical lifting provided by the lifting base, horizontal movement provided by the translational seat, and obstacle-avoidance frame enabling obstacle-crossing translation—the pipe can flexibly adjust its posture in space, significantly improving installation convenience and construction efficiency in complex pipe gallery scenarios. Simultaneously, the supporting wing arm and sliding wing arm components adopt a parallelogram linkage structure, ensuring the pipe placement frame remains horizontal throughout the lifting and lowering process. Combined with a clamping and fixing device for reliable locking of the pipe to be installed, this effectively prevents pipe tilting or detachment during lifting and translation, improving the safety of high-altitude operations. The invention features a reasonable structural design and simple operation, suitable for both sequential installation of multi-layer pipes in new construction projects and partial replacement work on existing pipelines during maintenance.

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0020] like Figure 1-6 In one embodiment of the present invention, the structure of the pipeline installation device includes: The lifting base 100 serves as the base and performs a vertical lifting action; The translation seat 200 is disposed at the top of the lifting base 100; The obstacle avoidance frame 300 is mounted on the translation seat 200. The lateral lifting device 310 and the central lifting device 330 of the obstacle avoidance frame 300 can be lifted relative to the translation seat 200 to pass over the interference pipe during the translation process and then reset. A support assembly 400 is mounted on the obstacle avoidance frame 300, and a pipe placement rack 450 is mounted on it for placing the pipes to be lifted and installed. 500 The lifting base 100 serves as the bottom component of the entire pipe installation device, providing support and functioning as a lifting and moving component. The translation base 200 allows the obstacle avoidance frame 300 and the support assembly 400 mounted on it to move laterally. The obstacle avoidance frame 300 is equipped with a lateral lifting device 310, a central lifting device 330, and a fixed lifting device 350. The tops of the lateral lifting device 310 and the central lifting device 330 are fixedly connected to the support assembly 400 via bidirectional hinges 340, allowing their bottom ends to fold inwards towards the obstacle avoidance frame 300. During use, if the pipe installation device is obstructed by an already installed pipe, thus interfering with the pipe installation, the lifting base 100 can be used to move the device. The obstacle avoidance frame 300 is lifted to a reasonable position, and then the horizontal translation seat 200 is used to move the obstacle avoidance frame 300 towards the interference pipe. Under the pressure of the interference pipe, the lateral lifting device 310 and the central lifting device 330 are lifted. At this time, the fixed lifting device 350 will temporarily provide support. When the interference pipe moves to the inside of the obstacle avoidance frame 300 and no longer contacts the lateral lifting device 310 and the central lifting device 330, the lateral lifting device 310 and the central lifting device 330 will reset. The re-erected obstacle avoidance frame 300 structure will be stabilized again and will no longer be affected by the interference pipe. Then, the support component 400 is used to fine-tune the pipe that has been placed on the pipe placement frame 450 to the installation position.

[0021] The lifting base 100 includes: a base plate 110; and base wheels 120 disposed at the bottom of the base plate 110. A lifting frame 130 is disposed on the top of the base plate 110; a lifting power device 140 is disposed on one side of the base plate 110, and its power output end is rotatably connected to the lifting frame 130, providing power for the lifting action of the lifting frame 130.

[0022] The base plate 110 is equipped with base wheels 120, and the movement of the entire equipment is achieved by the movement of the base wheels 120. Furthermore, in order to ensure the stability of the equipment when it is parked, support feet for fixed support can also be provided on the base plate 110. The lifting frame 130 installed on the base plate 110 can realize the lifting action, and its power is provided by the lifting power device 140.

[0023] In addition, the translation base 200 includes: a plate frame 210, which is rotatably connected to the top of the lifting frame 130, and the plate frame 210 is a hollow U-shaped structure; a translation device 220, which is disposed in the hollow structure inside the plate frame 210 and is fixedly connected to the plate frame 210; and a follower plate 230, which is fixedly connected to the upper surface of the translation device 220 and can move with the translation device 220.

[0024] The plate frame 210 on the translation base 200 is fixedly connected to the lifting frame 130, serving as the installation base for the upper components. The plate frame 210 is a hollowed-out U-shaped structure, and a translation device 220 is set in the hollowed-out part. Preferably, the translation device 220 is a track assembly. By fixing the follower plate 230 on the translation device 220, the follower plate 230 can be moved when the translation device 220 performs translational movement. At the same time, the range of motion of the follower plate 230 is limited, and the range of motion of the follower plate 230 can be limited by setting a limit switch 470 at the limit of the movement range.

[0025] like Figure 5 As shown, in one embodiment of the present invention, the obstacle avoidance frame 300 includes: a lateral lifting device 310, the bottom end of which is movably abutted against the follower plate 230, and the top end of which is rotatably connected to a lifting mounting plate 370 via a bidirectional hinge 340; a central lifting device 330, the bottom end of which is movably abutted against the follower plate 230, and the top end of which is rotatably connected to the lifting mounting plate 370 via a bidirectional hinge 340; and a fixed lifting device 350, the bottom end of which is fixedly connected to the follower plate 230, and the top end of which is rotatably connected to the lifting mounting plate 370 via a unidirectional hinge 320.

[0026] The obstacle avoidance frame 300 does not have a completely fixed connection structure. Its main structure consists of a lateral lifting device 310, a central lifting device 330, and a fixed lifting device 350 as upper-level supports. The upper ends of all three are connected to the lifting mounting plate 370. The lateral lifting device 310 is fixedly connected to the lifting mounting plate 370 via a two-way hinge 340. The central lifting device 330 is fixedly connected to the lifting mounting plate 370 via a two-way hinge 340. The top of the fixed lifting device 350 is fixedly connected to the lifting mounting plate 370 via a one-way hinge 320. The entire obstacle avoidance frame 300 is moved by the translation seat 200. The lateral lifting device 310, the central lifting device 330, and the fixed lifting device 350 are all connected to the lifting mounting plate 370 via a two-way hinge 340. The spacing between the zeros is set according to actual needs. Its effect is as follows: when the obstacle avoidance frame 300 moves with the translation seat 200, the interference pipe presses against the lateral lifting device 310, causing it to lift. At this time, the central lifting device 330 and the fixed lifting device 350 can act as supports to ensure the stability of the entire equipment. Continuing to move inward, the interference pipe disengages from the lateral lifting device 310, causing the lateral lifting device 310 to reset. Continuing to move, the interference pipe presses against the central lifting device, causing it to lift. Thus, while avoiding the interference pipe, the position adjustment of the entire equipment is completed. The single-leaf structure of the fixed lifting device 350 allows lifting by only the lateral and central lifting structures, increasing fault tolerance. After installation, the interference pipe can be removed along its original path.

[0027] like Figure 2-6 In one embodiment of the present invention, the support component 400 further includes: The support frame 410 is fixedly connected to the lifting mounting plate 370, and a pressing power device 420 is fixedly installed on it. The power output end of the pressing power device 420 is fixedly connected to a pressing rod 430. The supporting wing arm 440 includes a vertical positioning rod 441, a first wing arm 442, a second wing arm 443, and a follower positioning rod 444, wherein: The vertical positioning rod 441 is rotatably connected to the first wing arm 442 and the second wing arm 443, and forms a parallelogram structure with the follower positioning rod 444, while the vertical positioning rod 441 is fixedly connected to the lowering rod 430. The first wing arm 442 and the second wing arm 443 are rotatably connected to the support frame 410, so that the follower positioning rod 444 and the vertical positioning rod 441 are always parallel, and the tube placement frame 450 is fixedly installed on the outside of the follower positioning rod 444.

[0028] The support frame 410 serves as the mounting base for supporting other components of the assembly 400, and is also a load-bearing structure. It is fixedly mounted on the lifting mounting plate 370, and a downward pressing power device 420 is installed on it. The power output end of the downward pressing power device 420 is fixedly connected to the downward pressing rod 430. When the downward pressing power device 420 extends, the downward pressing rod 430 drives the vertical positioning rod 441 to move downward, which in turn drives the first wing arm 442 and the second wing arm 443 to rotate around their rotation center. At the same time, since the vertical positioning rod 441, the first wing arm 442, the second wing arm 443 and the follow-up positioning rod 444 form a parallel structure... Because of its quadrilateral shape, the follower positioning rod 444 always maintains the same direction as the vertical positioning rod 441 throughout the entire movement. Since the vertical positioning rod 441 always points vertically downward, the follower positioning rod 444 also always points vertically downward. The pipe rack 450, which is fixedly connected to the follower positioning rod 444, always points upward. Its V-shaped structure can adapt to pipes of various sizes to the greatest extent and also provide considerable stability for placing pipes. Combined with the directional stability of the follower positioning rod 444, the pipe will be placed with maximum stability, while also minimizing the difficulty of positioning.

[0029] Furthermore, since the presence of interfering pipes in actual use limits the placement height and horizontal position of the pipe installation device, in one embodiment of the present invention, the support assembly 400 further includes a sliding wing arm assembly 460, the structure of which includes: The first sliding wing arm 461 has one end slidably disposed on the upper surface of the first wing arm 442 via a sleeve ring 462, and the other end is rotatably connected to the sliding guide arm 465 and the follower mounting arm 466. The second sliding wing arm 463 has one end rotatably connected to the follower positioning rod 444, and the other end rotatably connected to the sliding guide arm 465 and the follower mounting arm 466. The follower mounting arm 466, the second sliding wing arm 463, the first sliding wing arm 461 and the follower positioning rod 444 form a parallelogram structure, so that the follower mounting arm 466 and the follower positioning rod 444 always remain parallel. The sliding power device 464 is fixedly installed at the lower end of the first wing arm 442. Its power output end is rotatably connected to the sliding guide arm 465, and provides power for the movement of the first sliding wing arm 461 and the second sliding wing arm 463 through the sliding guide arm 465. The tube holder 450 is also provided on the follow-up mounting arm 466.

[0030] The support assembly 400 is equipped with a sliding wing arm that can slide along the first wing arm 442. The sliding wing arm can provide an additional positioning range in the lateral direction. At the same time, in conjunction with the lifting function of the first wing arm 442 and the second wing arm 443, the adjustment range of the entire support assembly 400 is greatly improved. The power for the back-and-forth sliding of the sliding wing arm comes from the sliding power device 464 installed at the lower end of the first wing arm 442. Its power output end is rotatably connected to the sliding guide arm 465. In the sliding wing arm assembly 460, the first sliding wing arm 461, the second sliding wing arm 463, the follower mounting arm 466, and the follower positioning rod 444 also form a parallelogram structure. This makes the follower mounting arm 466 always remain parallel to the vertical positioning rod 441. Therefore, the tube rack 450 installed on the follower mounting arm 466 will also remain upward.

[0031] like Figure 7 As shown, in one embodiment of the present invention, the supporting wing arm 440 and the follow-up positioning rod 444 further include a clamping and fixing device 445, and the outer side of the pipe placement frame 450 is provided with a fixing hole 451. The two are fixed to the pipe placed on the pipe placement frame 450 by the fixing cable 4454 on the clamping and fixing device 445.

[0032] To ensure the stable placement of the pipe on the pipe rack 450 and prevent it from falling off due to sudden up-and-down movement of the pipe rack 450, a clamping and fixing device 445 is provided on the supporting wing arm 440 and the follow-up positioning rod 444. A fixing hole 451 is provided on the outside of the pipe rack 450. The two positions can be tied and fixed by connecting the two positions with ropes or rigid components suitable for the pipe size. After the pipe is installed, the clamping and fixing device 445 is disconnected. When the supporting wing arm 440 descends, the pipe position is maintained. As the supporting wing arm 440 descends, the pipe provides an upward pulling force to the rope or rigid component, thereby causing the rope or rigid component to fall off the clamping and fixing device 445, achieving controllable disconnection without manual intervention.

[0033] Furthermore, to ensure that the rope or rigid component can be securely and controllably fixed by the clamping and fixing device 445, in one embodiment of the present invention, the clamping and fixing device 445 includes: The outer casing 4451 is fixedly mounted on the supporting wing arm 440 and the follower positioning rod 444; A pair of movable clamps 4452 are rotatably disposed on the inside of the outer casing 4451; A clamping power device 4453 is disposed inside the movable clamp 4452 and provides power for the opening action of the movable clamp 4452; A rigid cable head 4455 is fixedly connected to one end of the fixed cable 4454, and has an annular groove 4456 that cooperates with the movable clamp 4452. The other end of the fixed cable 4454 is fixedly connected to the fixing hole 451.

[0034] Since a tube holder 450 is provided on the follower positioning rod 444 or the supporting wing arm 440, the outer shell 4451 is fixed on the follower positioning rod 444 or the supporting wing arm 440. The outer shell 4451 serves as the mounting base for the remaining parts of the clamping and fixing device 445. A pair of movable clamps 4452 are rotatably provided, which can rotate around their rotatable connection. A clamping power device 4453 provides power, preferably an electromagnet. Correspondingly, the movable clamps 4452 are made of magnetic material and can be controlled by the electromagnet to attract. The annular slot 4456 into which the rigid cable head 4455 is inserted is held by the protrusion on the movable clamp 4452. When the electromagnet stops attracting, the rigid cable head 4455 into the clamping and fixing device will be pulled out of the movable clamp 4452 under the pull of the pipe, thus disconnecting the electromagnet. The first wing arm 442 descends, and the fixing cable 4454 automatically disconnects.

[0035] As shown in the figure, the present invention also provides a method for using and recycling a pipeline installation device, the steps of which are as follows: Place the pipe to be installed on the pipe rack 450, insert the rigid cable head 4455 into the movable clamp 4452 and lock it; Move the lifting base 100 below the installation position and use the lifting base 100 to lift the pipe to the initial target height; Move the obstacle avoidance frame 300 to one side of the interference pipe, and translate the translation seat 200 so that the lateral lifting device 310 and the central lifting device 330 are lifted during the translation process, allowing the interference pipe to enter the space between it and the fixed lifting device 350 until the lifting mounting plate 370 is erected above the interference pipe. Then, reset the lateral lifting device 310 and the central lifting device 330. The pipe position is finely adjusted by the supporting wing arm 440 and the sliding wing arm assembly 460 to align it and place it in the designed installation position, thus completing the installation. After installation, open the movable clamp 4452, drive the supporting wing arm 440 and the sliding wing arm assembly 460 to retract, so that the rigid cable head 4455 can be dislodged and the pipe can be released from its fixation. The obstacle avoidance frame 300 is moved out from above the interference pipe, and then the entire device is moved out to complete the recovery.

[0036] The entire process is as follows: First, place the pipe to be installed on the pipe support 450, and insert the rigid cable head 4455 into the movable clamp 4452 to lock it in place, thus completing the reliable fixation between the pipe and the device. This fixing method adopts a plug-in locking structure, which is convenient to operate and can effectively prevent the pipe from shifting or falling off during subsequent jacking and translation processes, ensuring construction safety.

[0037] Next, the lifting base 100 is moved below the installation location, and the pipe is raised to the initial target height using the lifting base 100. This step utilizes the vertical lifting function of the lifting base 100 to raise the pipe from a low ground position to a position close to the installation elevation, providing a height basis for subsequent obstacle avoidance, horizontal movement, and precise positioning.

[0038] Then, the obstacle avoidance frame 300 is moved to one side of the interfering pipe, and the translation seat 200 is moved horizontally, causing the lateral lifting device 310 and the central lifting device 330 to be raised during the translation process, allowing the interfering pipe to enter the space between it and the fixed lifting device 350, until the lifting mounting plate 370 is erected above the interfering pipe. Then, the lateral lifting device 310 and the central lifting device 330 are reset. This step is necessary because in multi-layer integrated support and hanger scenarios, the installed pipes constitute spatial obstacles that traditional installation methods cannot overcome. This invention, through the design that the lateral lifting device 310 and the central lifting device 330 can be raised relative to the translation seat 200, allows the obstacle avoidance frame 300 to actively or passively clear the space occupied by the interfering pipe during horizontal movement. After the obstacle avoidance frame 300 reaches above the interfering pipe, it is reset, thereby achieving the translational movement to "cross" the obstacle and solving the problem of existing pipelines blocking the construction path.

[0039] Then, the pipe position is finely adjusted using the support arm 440 and the sliding arm to align it and place it in the designed installation position, completing the installation. This step utilizes the lifting and fine-tuning function of the support arm 440 and the horizontal extension function of the sliding arm to precisely adjust the position of the pipe to be installed, ensuring that the pipe flange or interface is accurately aligned with the existing pipeline, thus guaranteeing installation quality.

[0040] After installation, open the movable clamp 4452, drive the supporting wing arm 440 and the sliding wing arm to retract, causing the rigid cable head 4455 to disengage and release the fixation to the pipe. This step uses the opposite unlocking operation as step one, disconnecting the device from the installed pipe and preparing for the device to be removed.

[0041] Finally, the obstacle avoidance frame 300 is removed from above the interfering pipe, and then the entire device is removed to complete the recovery. This step involves exiting the construction area in the reverse order of entry to achieve complete recovery of the device, facilitating the installation of the next section of pipe.

[0042] The above method can complete the entire process of lifting, obstacle crossing, alignment, installation, and equipment retrieval of large-diameter pipelines in a single operation in complex multi-layer integrated support and hanger environments, resulting in a smooth and efficient construction process. Compared with traditional methods, this invention can complete obstacle avoidance and pipe relocation without disassembling existing pipelines, significantly reducing manual intervention and high-altitude work time, lowering labor intensity and safety hazards. Simultaneously, the reliable locking of the clamping and fixing device 445 and the stable support of the supporting wing arm 440 ensure the stability of the pipeline throughout the installation process, effectively improving construction quality and operational safety.
