Description

Technical Field

[0001] This invention relates to the field of pipeline installation technology, and in particular to a multifunctional pipeline transportation and alignment device and its operation method. Background Technology

[0002] In pipeline installation projects in fields such as petrochemicals, municipal construction, and industrial plants, indoor pipeline laying is a crucial step. Due to confined indoor spaces, numerous obstacles, complex ground conditions, and the frequent involvement of heavy pipelines with diameters ranging from DN250mm to DN800mm, transportation and joint alignment (connection) operations have always presented significant challenges. Traditional construction methods are inadequate in such environments, resulting in low construction efficiency and posing a potential threat to pipeline installation quality. Therefore, there is an urgent need for a specialized tool that can adapt to complex indoor conditions and integrate various functions.

[0003] Currently, the most common technical methods used in indoor pipe installation rely on a combination of simple machinery and manual labor. For pipe transportation, manual rollers or ropes are typically used for dragging. When greater traction is required, winches or other powered equipment are used to pull the pipe directly with steel cables. For pipe alignment, workers primarily rely on prying tools like crowbars to manually move the pipe ends, supplemented by visual inspection and experience to align the joints horizontally and vertically, ultimately achieving preliminary alignment of the two pipe sections.

[0004] However, the aforementioned existing technologies have significant drawbacks. In particular, when using a winch to directly pull or manually drag the pipeline, the lack of effective support and protection for the pipe body makes it highly susceptible to collisions with the ground or obstacles, resulting in pipe damage or curling. Simultaneously, the pipeline is prone to sucking in foreign objects such as mud during dragging. If these damages and foreign objects are not detected and addressed before welding, they will directly lead to substandard welding quality, posing serious quality and safety hazards to the entire pipeline system. Summary of the Invention

[0005] The purpose of this invention is to address the problems existing in the background art by proposing a multifunctional pipeline transportation and docking device and its operation method.

[0006] In a first aspect, this application provides a multifunctional pipeline transportation and alignment device, including a lower support beam, and further comprising: Adjustment mechanisms are provided on both sides of the lower support beam, and a connecting rod is installed in the middle of the lower support beam. The outer wall of the connecting rod has a rotating ring, and a drag rod is threadedly installed on the outer wall of the rotating ring. A limit support mechanism is provided at the top of the connecting rod. The limiting support mechanism includes a rotating shaft that rotates inside the connecting rod. A threaded post is threadedly installed on the top of the rotating shaft. An upper bracket two and an upper bracket one are sequentially fitted on the outer wall of the threaded post from top to bottom. The upper bracket two and the upper bracket one each have a different number of slots. The lower surface of the upper bracket two is fixed with a block that is the same number and position as the slots.

[0007] Optionally, a handle is fixed to the top of the threaded post, and a spring pin is provided inside the threaded post. The number of spring pins is the same as the number of slots and their positions correspond.

[0008] Optionally, the adjustment mechanism includes a hinge, one side of which is installed on both sides of the outer wall of the lower support beam, and the other side of which is installed with an adapter plate.

[0009] Optionally, the device may also include an extension mechanism disposed inside the adapter plate; The extension mechanism includes an adjustment plate that can slide inside the adapter plate. An extension plate is fixedly installed at one end of the adjustment plate, and an elastic slot plate is fixed to the inner wall of the extension plate.

[0010] Optionally, a limiting block and a limiting plate slide inside the adapter plate. The limiting plate is fixed to one side of the outer wall of the limiting block. A telescopic rod is fixed to one side of the outer wall of the limiting block. One end of the telescopic rod is fixed inside the adapter plate, and a spring is sleeved on the outer wall of the telescopic rod.

[0011] Optionally, both the adjusting plate and the adapter plate have multiple limiting grooves inside. One end of the spring is fixed to one side of the outer wall of the limiting block, and the other end is fixed inside the adapter plate.

[0012] Optionally, the limiting block can slide into the limiting groove, and the upper bracket can slide into the elastic slot plate for limiting.

[0013] Optionally, one of the extension plates has a T-shaped slot inside, and the other extension plate has a T-shaped limiting post fixed at its end that can slide inside the T-shaped slot.

[0014] Optionally, a traveling wheel is installed on the lower surface of the extension plate, and a pipe body is provided between the upper bracket one and the upper bracket two.

[0015] Secondly, the present invention provides a multifunctional pipeline transportation and alignment operation method, applied to the multifunctional pipeline transportation and alignment device described in the first aspect, the method comprising the following steps: S1. Place the pipe body between the upper bracket one and the upper bracket two. Adjust the fit between the first clamp and the first clamp at different positions so that the support surface formed by the upper bracket one and the upper bracket two adapts to the outer diameter of the pipe. Supported by the traveling wheels, and operate the drag rod to pull the entire device and the pipe to move. S2. Transport the two devices with loaded pipes to the matching positions respectively, and make coarse adjustments to the left and right directions of the pipes in the horizontal plane by pushing, pulling or swinging the drag bar. S3. Adjust the extension length of the extension plate by pulling the adjustment plate to fine-tune the pipe spacing; use the drag rod with its end as the fulcrum; S4. When multiple pipe sections need to be moved synchronously, slide the T-shaped limiting post of one device into the T-shaped slot of another device to connect multiple devices into one unit; after the pipe alignment accuracy meets the requirements, spot weld to fix it.

Through an adjustable support mechanism and flexible traction method, it replaces the traditional inefficient manual handling and rough alignment operation, significantly improving construction efficiency and safety, and effectively preventing damage to pipe openings and foreign object intrusion during transportation.

[0017] Furthermore, by using the lever principle of the drag rod for precise vertical alignment and combining it with the extension mechanism for fine-tuning left and right, high-precision alignment is achieved, ensuring welding quality and long-term stable operation of the pipeline system.

[0018] Finally, the device adopts a split, foldable design and is equipped with an expandable support and extension mechanism, which makes it adaptable to different pipe diameters and complex terrains, and facilitates transportation, storage and rapid deployment in narrow indoor spaces. It is highly versatile, has low manufacturing costs and is recyclable. Attached Figure Description

[0021] 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.

[0022] like Figures 1-3 As shown, the present invention proposes a multifunctional pipeline transportation and alignment device, including a main load-bearing base lower support beam 1 and an adjustment mechanism for adaptive terrain adjustment and folding hubs; in one embodiment, adjustment mechanisms are provided on both sides of the lower support beam 1, a connecting rod 4 is installed in the middle, a rotating ring 5 is rotatably mounted on the outer wall of the connecting rod 4, a drag rod 6 is threadedly mounted on the outer wall of the rotating ring 5, and a limit support mechanism is provided at the top of the connecting rod 4; a traveling wheel 8 is installed on the lower surface of the extension plate 18. The device is described in detail below: In this embodiment, the connecting rod 4 is fixed to the middle of the lower support beam 1, and the rotating ring 5 sleeved on its outer wall can rotate freely around the axis of the connecting rod 4. By rotating the rotating ring 5, the circumferential angle of the drag rod 6 connected to its outer wall can be adjusted to adapt to the traction requirements in different directions. When transporting the pipeline, the operator or external traction equipment can easily pull or push the entire device and pipeline to move by acting on the drag rod 6. During the initial left and right adjustment at the joint, the left and right alignment of the pipeline on the horizontal plane can be achieved by swinging or pushing and pulling the drag rod 6.

[0023] like Figures 1-7 As shown, the device also includes a limiting support mechanism; in one embodiment, the limiting support mechanism includes a rotating shaft 9 that rotates inside the connecting rod 4. A threaded post 14 is threaded on the top of the rotating shaft 9. The outer wall of the threaded post 14 is fitted with an upper bracket 2 11 and an upper bracket 10 from top to bottom. The upper bracket 2 11 and the upper bracket 10 are both provided with a different number of slots 12. The lower surface of the upper bracket 2 11 is fixed with a number of slots 13 that are the same as the number of slots 12 and the corresponding positions. A handle 17 is fixed to the top of the threaded column 14, and a spring pin 15 is provided inside the threaded column 14. The number of spring pins 15 and the position of the second slot 16 are the same. A pipe body 22 is provided between the first upper bracket 10 and the second upper bracket 11. The limiting support mechanism is described in detail below: In this embodiment, the rotating shaft 9 rotates inside the connecting rod 4, allowing the upper support structure to swing slightly to fit the pipe. The upper bracket 10 and the upper bracket 21 are interlocked by different numbers of slots 12 inside them and corresponding blocks 13 fixed to the bottom of the upper bracket 21, forming an expandable V-shaped or arc-shaped bracket. By selecting different mating positions of slots 12 and blocks 13, the opening degree of the bracket can be changed to adapt to various pipe diameters. In addition, by rotating the threaded column 14, the threaded column 14 is threadedly engaged with the top of the rotating shaft 9, thereby fixing the upper bracket 10 and the upper bracket 21. The spring pin 15 inside the threaded column 14 automatically pops out under the action of spring force and is embedded in the slot 2 16 on the side wall of the threaded column 14 or related fixing parts, effectively preventing accidental rotation under load and ensuring the stability of the support height.

[0024] like Figures 1-6 As shown, the device also includes an adjustment mechanism; in one embodiment, the adjustment mechanism includes a hinge 2, one side of the outer wall of the hinge 2 is installed on both sides of the outer wall of the lower support beam 1, and the other side of the outer wall is equipped with a transition plate 3; The limiting block 21 can slide into the limiting groove 20, and the upper bracket 11 can slide into the elastic slot plate 19 for limiting. The adjustment mechanism is described in detail below: In this embodiment, the hinge 2 allows the adapter plate 3 to rotate at a certain angle relative to the lower support beam 1. When encountering uneven ground, the tilt angle of the two adapter plates 3 can be adjusted independently to keep the device in a horizontal support state. When the lower support beam 1 and the adapter plate 3 are in a vertical state, the upper bracket 10 and the upper bracket 21 are completely fitted together during this process, and the two ends of the upper bracket 211 are locked into the elastic slot plate 19 for fixation, realizing folding and making it easy to carry.

[0025] like Figures 1-8 As shown, the device also includes an extension mechanism disposed inside the adapter plate 3; in one embodiment, the extension mechanism includes an adjustment plate 7 that can slide inside the adapter plate 3, an extension plate 18 is fixedly installed at one end of the adjustment plate 7, and an elastic slot plate 19 is fixed to the inner wall of the extension plate 18. The adapter plate 3 has a sliding limit block 21 and a limit plate 25 inside. The limit plate 25 is fixed to one side of the outer wall of the limit block 21. A telescopic rod 26 is fixed to one side of the outer wall of the limit block 21. One end of the telescopic rod 26 is fixed inside the adapter plate 3. A spring 27 is sleeved on the outer wall of the telescopic rod 26. Both the adjusting plate 7 and the adapter plate 3 have multiple limiting grooves 20 inside. One end of the spring 27 is fixed to one side of the outer wall of the limiting block 21, and the other end is fixed inside the adapter plate 3. The extension mechanism is described in detail below: In this embodiment, an adjustment plate 7 is slidably disposed inside the adapter plate 3. An extension plate 18 is fixed to one end of the adjustment plate 7. By pulling the adjustment plate 7, the extension plate 18 can be extended, thereby expanding the support span of the device. Both the adjustment plate 7 and the adapter plate 3 are provided with multiple limiting grooves 20. When the adjustment plate 7 is pulled to the desired position, under the elastic force of the spring 27, the limiting block 21 will be engaged in the corresponding limiting groove 20 to achieve quick positioning and locking. In addition, when multiple devices need to be connected side by side to form a longer support platform, the T-shaped slot 24 opened inside one extension plate 18 can cooperate with and slide with the T-shaped limiting post 23 at the end of the extension plate 18 of the adjacent device to achieve quick splicing of the device.

[0026] like Figures 1-8 As shown, the device also includes a T-shaped limiting post 23 and a T-shaped slot 24. In one embodiment, a T-shaped slot 24 is provided inside one of the extension plates 18, and a T-shaped limiting post 23 that can slide inside the T-shaped slot 24 is fixed at the end of the other extension plate 18. The T-shaped limiting post 23 and the T-shaped slot 24 are described in detail below: In this embodiment, when multiple upper brackets 10 and upper brackets 21 provide support, multiple vehicle bodies are then spliced ​​together through an extension mechanism. At this time, the T-shaped limiting posts 23 at both ends of the vehicle body are spliced ​​with the T-shaped slots 24.

[0027] like Figures 1-8 As shown, the present invention also provides a multifunctional pipeline transportation and docking operation method, which includes the following steps: S1. Place the pipe body 22 between the upper bracket 10 and the upper bracket 21. Adjust the cooperation between the locking block 13 and the locking slots 12 at different positions so that the support surface formed by the upper bracket 10 and the upper bracket 21 adapts to the outer diameter of the pipe. Supported by the traveling wheels 8, and operate the drag rod 6 to pull the entire device and the pipe to move. S2. Transport the two devices with loaded pipes to the matching positions respectively, and make coarse adjustments to the left and right directions of the pipes in the horizontal plane by pushing, pulling or swinging the drag bar 6. S3. Adjust the extension length of the extension plate 18 by pulling the adjustment plate 7 to fine-tune the pipe spacing; use the drag rod 6 with its end as the fulcrum. S4. When multiple pipe sections need to be moved synchronously, slide the T-shaped limiting post 23 of one device into the T-shaped slot 24 of another device to connect multiple devices into one unit; after the pipe alignment accuracy meets the requirements, spot weld to fix it.

[0028] Specifically, the operator first adjusts the limiting support mechanism according to the diameter of the pipe body 22 to be transported. By selectively engaging the locking block 13 on the lower surface of the upper bracket 2 11 with the locking groove 12 at different positions on the upper bracket 10, the opening degree of the V-shaped or arc-shaped bracket composed of the upper bracket 10 and the upper bracket 2 11 is changed, thereby stably supporting pipes of different diameters. After loading, the walking wheels 8 provide support. The operator can rotate the rotating ring 5 to a suitable angle and then hold the drag bar 6 for manual traction or connect external power equipment, thus easily transporting the pipe in complex indoor environments.

[0029] Move the two devices supporting the previous section of the pipe and the other two devices supporting the pipe to be aligned to the alignment area that are close to each other. By pushing or pulling the rod 6 in the left and right directions or swinging it slightly, the two sections of the pipe are initially aligned on the horizontal plane by using the slight displacement of the bottom of the device, so that the pipe openings are initially overlapped.

[0030] For fine adjustments in the left and right directions, the adjusting plate 7 inside the adapter plate 3 can be pulled out. The adjusting plate 7 drives the extension plate 18 at its end to extend or retract, thereby precisely controlling the support position of the device and finely adjusting the spacing of the pipe ports. When pulled to the desired position, the limiting block 21 inside the adapter plate 3 automatically engages with the limiting groove 20 on the adjusting plate 7 under the elastic force of the spring 27, thus locking it in place. For fine adjustments in the up and down directions, the end of the drag rod 6 is pressed against the ground as a fulcrum. The free end of the drag rod 6 is pressed down or raised, and the lever principle is used to make the entire bracket mechanism tilt slightly around the rotating shaft 9, thereby precisely raising or lowering the height of the pipe ports and completing the alignment on the vertical plane.

[0031] When aligning particularly long or heavy pipes, and it is necessary to ensure the synchronous movement of multiple support points, the splicing function of the device can be used. The T-shaped limiting post 23 at the end of one device extension plate 18 is slid into the T-shaped slot 24 inside the adjacent device extension plate 18, and multiple independent devices are rigidly connected into an integral frame, ensuring that they work together in a coordinated manner during the adjustment process. When the interface of the pipe body 22 reaches the required alignment accuracy in the four directions of left, right and up and down, spot welding can be performed to temporarily fix the interface, and then all welding work is completed.

[0032] In addition, when not in operation, the adapter plate 3 can be flipped upwards via the hinge 2 to make it perpendicular to the lower support beam 1. At the same time, the upper bracket 10 and the upper bracket 2 11 are closed, and the two ends of the upper bracket 2 11 are fixed by inserting them into the elastic slot plate 19 on the inner wall of the extension plate 18, so as to achieve compact folding of the device, which is convenient for storage and transportation.

[0033] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
