[0002] Pipeline construction is one of the core construction elements in various projects involving water conservancy systems, HVAC systems, petrochemical systems, and more. Pipeline construction inevitably involves connecting different pipelines, specifically installing flanges on two pipelines to connect multiple pipelines and form a complete pipeline.
[0003] When connecting two pipe flanges, both flanges are suspended in mid-air and are affected by the terrain and the weight of the pipes themselves. Traditional connection methods rely on a crane and manual calibration by multiple workers. This requires several workers to coordinate and calibrate the pipe to be connected and its flange to align with the other installed flange. Bolts are then installed in the mounting holes of both flanges to complete the connection. However, manually connecting two pipe flanges requires multiple workers to support the pipes, the construction environment is complex, and communication between workers and cranes is difficult, significantly increasing construction costs and the labor intensity of workers. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a pipe flange docking device to solve the problem that existing devices are inconvenient for docking two pipe flanges.

It also includes: at least two sliding rods connected to the support frame, with sliding frames slidably connected to the sliding rods; two pipe clamps connected to the sliding frames via lifting frames; and a lateral adjustment component and a longitudinal adjustment component mounted on the lifting frame.

The pipe clamp is provided with a second mounting base, and the first mounting base and the second mounting base are connected by bolts.
[0009] Furthermore, the lateral adjustment assembly includes a lateral threaded rod rotatably connected to the lifting plate, a lateral threaded block threadedly connected to the lateral threaded rod, and a tool slot connected to the end of the lateral threaded rod.

[0014] The technical solution of this utility model will be further described in a non-limiting manner below with reference to the accompanying drawings and specific embodiments.
[0015] like Figures 1-6As shown, the pipe flange docking device provided in this embodiment includes a support frame 1, which is formed by welding several metal pipes to form a structure that can bear the weight of the pipe. Lifting support leg assemblies are provided at the four corners of the support frame 1. The support frame 1 stands on the ground through the lifting support leg assemblies. The support frame 1 and the core structure of the device are divided into five modules, and each module works together to achieve precise docking of the pipe flange. Specifically, the device includes a sliding rod 2, a pipe clamp 3, a lateral adjustment assembly, and a longitudinal adjustment assembly. Specifically, at least two sliding rods 2 are provided, both connected to the support frame 1. A sliding frame 4 is slidably connected to each sliding rod 2. The length of the sliding rod 2 is determined by the length of the support frame 1, which in turn is determined based on actual use. The sliding rod 2 can be made of solid round steel or high-strength alloy pipe, with both ends fixed to the crossbeam at the top of the support frame 1 by bolts or welding. The two sliding rods 2 remain parallel, and their axial direction is consistent with the pipe connection direction. The surface of the sliding rod 2 is preferably polished to reduce sliding resistance. Two or at least two pipe clamps 3 are provided, each connected to the sliding frame 4 via a lifting frame 6. The pipe clamp 3 is a common clamping structure in pipe construction, mainly consisting of two arc-shaped clamping plates 5. When the two arc-shaped clamping plates 5 are joined together, a circular space suitable for pipe insertion is formed inside. After the two arc-shaped clamping plates 5 are joined together, they can be connected by bolts to form a stable integrated structure. In this device, for pipes of different diameters, the corresponding specifications of the pipe clamp 3 need to be replaced.
[0016] The lateral adjustment component and the longitudinal adjustment component are installed on the lifting frame 6, and both lifting frames 6 are equipped with the lateral adjustment component and the longitudinal adjustment component. The lateral adjustment component is installed on the lifting frame 6 and is used to drive the pipe clamp 3 to move laterally, that is, to move in the direction parallel to the plane where the support frame 1 is located. The longitudinal adjustment component is used to drive the pipe clamp 3 to move longitudinally, that is, to move in the direction perpendicular to the plane where the support frame 1 is located.
[0017] In use, one of the pipe clamps 3 is connected to the end of a fixed pipe, and a flange is connected to the end of the pipe. Because the pipe is fixed in a specific environment and is connected to other pipes, the pipe is in a fixed state. When the pipe clamp 3 is clamped on the pipe, the pipe clamp 3 will not slide on the slide bar 2 due to the influence of the pipe. The other pipe clamp 3 is connected to the pipe to be connected, and the flange on the pipe to be connected is opposite to the flange of the fixed pipe. The pipe to be connected is connected to the slide frame 4 through the pipe clamp 3 and the lifting frame 6. During the process of using the pipe clamp 3 to clamp and fix the pipe to be connected, multiple pipe clamps 3 can be set to clamp the pipe to be connected to provide stable support for the pipe to be connected.
[0018] The weight of the pipes to be connected is supported by the sliding rod 2 and the support frame 1. The operator can manually slide the pipe clamp 3. Under the action of the sliding rod 2, the pipe to be connected moves along the axial direction of the sliding rod 2. The flange of the pipe to be connected gradually approaches the fixed pipe and the flange connected to it. After the flanges on the two pipes are aligned, the pipe clamp 3 can be moved laterally by the lateral adjustment component to adjust the lateral position of the pipe. The pipe clamp 3 can also be moved longitudinally by the longitudinal adjustment component to adjust the longitudinal position of the pipe until the flange of the pipe to be connected is aligned with the fixed pipe flange and the mounting holes on the two flanges are connected. At this point, bolts can be used to stably connect the two pipe flanges. During this process, it is not necessary for multiple operators to support the pipes to be connected. Simply fix the flanged pipes to be connected onto the pipe clamp 3; no crane is needed to support the pipes, avoiding communication difficulties between the operator and the crane. Once the bolt holes of the two flanges are fully aligned, the operator passes the bolts through the aligned bolt holes, puts on the nuts, and tightens them to complete the connection and fixing of the two pipe flanges. Finally, loosen the pipe clamp 3, disassemble the device, and proceed to the next stage of construction. When moving and connecting the pipes, the sliding rod 2 facilitates the operator's movement of the pipes. With the sliding rod 2 supporting the pipe clamp 3, the operator's lifting and supporting of the pipes to be connected is reduced. Only a small amount of manpower is needed to move the pipes to be connected and connect the two pipe flanges, which helps reduce the labor intensity of workers and the frequency of crane use, thus reducing construction costs. Specifically, in order to facilitate adjustment of the overall height of the support frame 1 and adapt to different terrains, therefore, as Figure 1 , Figure 3 , Figure 5 as well as Figure 6As shown, the lifting outrigger assembly includes sleeves 7 connected to the four corners of the support frame 1, a lifting rod 8 slidably connected to the end of the sleeve 7 near the ground, foot plates 9 hinged to the end of the lifting rod 8 away from the sleeve 7, and a fixing pin 19. The hinged foot plates 9 can adaptively rotate with the ground slope to increase the contact area with the ground and prevent the foot plates 9 from sinking into soft soil. Several first through holes 81 are evenly distributed along the length of the lifting rod 8 on the lifting rod 8. A second through hole 10 is formed on the sleeve 7 and is movably connected to one of the first through holes 81. When the first through hole 81 and the second through hole 10 are connected, one end of the fixing pin 19 extends from one side of the sleeve 7 through the second through hole 10 and the first through hole 81 to the other side of the sleeve 7. When it is necessary to support a pipe, the fixing pin 19 is... The support frame 1 is placed in a suitable location on the construction site. The lifting foot assemblies at its four corners provide support for the support body. When the construction ground is uneven, the fixing pin 19 can be removed, and the lifting rod 8 can be moved along the extension direction of the sleeve 7 until the foot plate 9 on the lifting rod 8 is in stable contact with the ground. Then, the fixing pin 19 extends from one side of the sleeve 7 through the second through hole 10 and the first through hole 81 to the other side of the sleeve 7. At this time, the lifting rod 8 is fixed on the sleeve 7. The other lifting foot assemblies are adjusted one by one to place the support frame 1 stably on the site. Under the action of the lifting foot assemblies, it can adapt to uneven ground. When the construction ground is flat, the four lifting foot assemblies can be adjusted to be at the same height to adapt to flat ground. In this process, by setting the lifting foot assemblies on the support frame 1, the adaptability of the device to the usage scenario can be improved.
[0019] To prevent the fixing pin 19 from easily disengaging from the first through hole 81 and the second through hole 10, locking grooves 11 extend radially from both the first through hole 81 and the second through hole 10. The end of the fixing pin 19 is provided with a locking protrusion 12 suitable for passing through the locking groove 11. At the end of the fixing pin 19 away from the locking protrusion 12, a handle 20 is provided that bends toward one side of the locking protrusion 12. When the fixing pin 19 extends from one side of the sleeve 7 through the second through hole 10 and the first through hole 81 to the other side of the sleeve 7, the handle 20 and the locking protrusion 12 are affected by gravity and hang freely. After changing position, the locking protrusion 12 is blocked by the outer wall of the sleeve 7 and will not easily disengage from the first through hole 81 and the second through hole 10, thus fixing the position of the fixing pin 19 and improving the safety of the device.
[0020] Furthermore, the sliding frame 4 includes a moving rod 13 and a sliding seat 14 connected to the moving rod 13. The sliding seat 14 is slidably connected to the sliding rod 2. The lifting frame 6 includes a lifting plate 15, a guide rod 16 connected to the lifting plate 15, a mounting plate 18 slidably connected to the guide rod 16 via a guide block 17, and a first mounting base 180 connected to the mounting plate 18. The pipe clamp 3 is provided with a second mounting base 21. The first mounting base 180 and the second mounting base 21 are connected by bolts. For ease of use, one of the arc-shaped clamps of the pipe clamp 3 can be pre-installed on the first mounting base 180 via the second mounting base 21. When clamping and constraining the pipe, simply align the arc-shaped clamp with the other arc-shaped clamp and then fasten it with bolts. Alternatively, the two arc-shaped clamps can be clamped and installed on the pipe first, and then the pipe can be lifted so that the first mounting base 180 aligns with the second mounting base 21. The first mounting base 180 and the second mounting base 21 can be fixedly connected by bolts. The specific method can be determined according to actual use.
[0021] Furthermore, the lateral adjustment assembly includes a lateral threaded rod 22 rotatably connected to the lifting plate 15, a lateral threaded block 23 threadedly connected to the lateral threaded rod 22, and a tool slot 24 connected to the end of the lateral threaded rod 22. The lateral threaded block 23 is connected to the mounting plate 18 and is slidably connected to the guide rod 16. One end of the lateral threaded rod 22 passes through the lifting plate 15 and is connected to the tool slot 24. Tools such as pry bars can be connected to the tool slot 24. The lateral threaded rod 22 is rotated through the tool slot 24. When the lateral threaded rod 22 rotates, the lateral threaded block 23 can be moved under the action of the guide rod 16, thereby causing the mounting plate 18 to move along the axial direction of the lateral threaded rod 22. Depending on the rotation direction of the lateral threaded rod 22, the mounting plate 18 can be moved back and forth, thereby completing the lateral adjustment of the pipeline.
[0022] Furthermore, such as Figure 3 As shown, the longitudinal adjustment assembly includes a longitudinal threaded rod 25 rotatably connected to a lifting plate 15 at one end, a longitudinal threaded block 26 connected to a moving rod 13, and a rotating handle 28 connected to the other end of the longitudinal threaded rod 25. The longitudinal threaded rod 25 passes through the longitudinal threaded block 26 and is threadedly connected to the longitudinal threaded block 26. A limiting rod 27 is connected to the lifting plate 15 along the axial direction of the longitudinal threaded rod 25. The end of the limiting rod 27 away from the lifting plate 15 passes through the moving rod 13 and is slidably connected to the moving rod 13. Rotating the rotating handle 28 causes the longitudinal threaded rod 25 to rotate. When the longitudinal threaded rod 25 rotates, under the action of the limiting rod 27, the lifting plate 15 and the mounting plate 18 can be moved along the axial direction of the moving longitudinal threaded rod 25, thereby completing the longitudinal adjustment of the pipeline.
[0023] It should be noted that when this device is used in harsh construction environments, considering the large amount of sand, soil, and dust in the environment, the structure of the device needs to be cleaned before and after use to avoid jamming or locking between the components. The device has a simple structure and is easy for workers to clean.

It should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. Modifications and variations made by those skilled in the art without departing from the spirit and scope of the present invention should be within the protection scope of the appended claims.
