Description

Technical Field

[0001] This invention belongs to the field of pipeline installation in steel pipe corridors, specifically relating to a pipeline installation device, installation system and installation method for steel structure pipe corridors. Background Technology

[0002] In the construction of modern industrial park infrastructure, steel pipe corridors are increasingly widely used as the core load-bearing structure for industrial pipelines. However, later-stage pipeline installation faces key challenges such as the straight pipe section length exceeding the spacing between the steel pipe corridor columns and the inability to hoist the pipeline into the middle layer of the corridor due to obstruction by crossbeams. Traditional pipeline installation processes employ a combination of "static sliding pipe supports + manual high-altitude operations + reciprocating hoisting with lifting equipment," as detailed below: Pipeline transportation: For pipe sections longer than the spacing between the pipe rack columns (e.g., a 12m straight pipe section is selected when the column spacing is 9m), the pipe is lifted from the side of the pipe rack by a truck crane, and then manually pulled and pushed to force it through the column gaps and into the pipe rack; for pipe sections shorter than the spacing between the pipe rack columns (e.g., 6m), a monorail crane is used to lift the pipes to the installation position section by section, and the crane needs to be moved repeatedly to adjust the landing point. Pipe support: The installation position of traditional sliding pipe support is marked on the crossbeam of the steel pipe gallery. Temporary scaffolding is erected manually at high altitude. After measurement and calibration, the base of the sliding pipe support is welded and fixed to the crossbeam. The pipe support and the pipe are only supported by static friction, without active limiting structure. Pipe welding: After the pipe is placed on the sliding pipe support, the worker stands in the scaffold or crane basket, adjusts the connection accuracy of the two pipe sections in the air, and uses a welding gun to complete the circumferential weld; after welding, the pipe position needs to be adjusted again to ensure that it is consistent with the design elevation.

[0003] Traditional installation methods rely on manual hoisting, which has the following drawbacks: Defect 1: Difficulty in installing long pipes into the corridor: The distance between long pipe sections and columns does not match, making them prone to getting stuck when entering the corridor. Multiple people are needed to forcibly drag them, which may cause deformation of the corridor beams and scratches on the outer wall of the pipes, and the adjustment time is long.

[0004] Defect 2: Unstable short pipe support: The short pipe section has no temporary support. After being hoisted to the installation position, it needs to be manually supported or temporarily tied and fixed, which is prone to pipe shaking and increases the risk of welding deviation; the monorail crane has low efficiency in reciprocating transportation.

[0005] Defect 3: High risk of working at height: When welding in the air, personnel have no stable working surface, and the docking deviation needs to be readjusted. In addition, the pipeline has no fall protection limit, and once the binding is loose, it is easy to cause a safety accident. The high-altitude calibration of the sliding pipe support requires personnel to move on the crossbeam, and the risk of falling is significant when there are no protective measures.

[0006] Defect 4: Low space utilization: Pipelines at multiple elevations need to be constructed sequentially, and work cannot be carried out on the upper level before the lower level pipelines are completed; in high-density pipeline scenarios, conflicts occur frequently on the work surface, requiring frequent equipment relocation, which further reduces efficiency.

[0007] Currently, industry research on steel pipe gallery installation focuses on improving individual equipment (such as optimizing hoisting hooks and enhancing the wear resistance of sliding pipe supports), and has not formed an integrated technical system of "transportation-welding-positioning-support". Systematic solutions for large-span pipe galleries are still lacking, and there is an urgent need to upgrade the technology through structural innovation and process reconstruction. Summary of the Invention

[0008] To address the aforementioned issues, this invention constructs an innovative technical system centered on "rolling pipe support - welding platform - guide rod," achieving a technological upgrade in steel pipe gallery installation from "manual and extensive operation" to "precise mechanical operation."

[0009] According to a first aspect of this application, a steel structure pipe gallery pipe installation device is provided, comprising: Multiple rolling pipe supports are installed on the crossbeams of each steel pipe gallery along the length of the steel pipe gallery. The rolling pipe supports have conveying rollers for supporting and conveying the pipes. Multiple welding platforms are installed at set intervals along the length of the steel pipe rack for pipe end welding connections. Multiple guide rods are connected to each welding platform to guide the pipe into the welding platform.

[0010] Optionally, each rolling tube support is fixedly connected to the steel tube gallery beam via a base. A pair of columns are spaced apart at the upper end of the base, and a pair of conveying rollers are inclinedly connected between the columns and the base with their upper ends facing away from each other.

[0011] Optionally, each column has a rectangular limiting hole at its upper end, and the lower end of each limiting rod is inserted into the limiting hole. A pipe clamp is fixedly connected to the upper end of each limiting rod. The pipe clamp is used to weld to the side wall of the pipe after the pipe is installed in place.

[0012] Optionally, the dimensions of the limiting hole and the limiting rod are designed according to the maximum allowable axial displacement and maximum radial displacement of the pipeline as required by the design. The difference between the axial dimension of the limiting hole and the limiting rod in the pipeline is twice the maximum axial displacement, and the difference between the radial dimension of the limiting hole and the limiting rod in the pipeline is twice the maximum radial displacement.

[0013] Optionally, the height of the welding platform is equal to or 10 mm to 30 mm below the lowest point of the pipe supported on the rolling tube support.

[0014] Optionally, a mounting plate is fixedly connected to the upper edge of the welding platform. The mounting plate has a second mounting hole and a plurality of first mounting holes around the second mounting hole. The guide rod is installed obliquely on the outside of the width direction of the welding platform by bolts passing through the first mounting hole, the second mounting hole, and the guide rod.

[0015] Optionally, the end shape of the pipe clamp is adapted to the outer contour of the pipe.

[0016] According to a second aspect of this application, a steel structure pipe gallery pipeline installation system is provided, comprising multiple sets of the above-described steel structure pipe gallery pipeline installation devices, each set being arranged vertically at intervals in the steel structure pipe gallery for the installation of multi-layer pipelines in the steel structure pipe gallery.

[0017] According to a third aspect of this application, a method for installing pipelines in a steel structure pipe gallery is provided, which uses the steel structure pipe gallery installation device described above and performs the following steps: Step S1: Determine the number of pipe installation devices for the steel structure pipe gallery based on the number of pipe installation layers, and install the corresponding rolling pipe supports on the crossbeams of the steel pipe gallery according to the pipe positions of each layer. Step S2: For the floor where the pipe is to be installed, use mechanical hoisting equipment and guide rods to send the pipe section into the welding platform of the corresponding floor and place it on the rolling pipe support. Use the rolling pipe support to push the pipe section to the welding position. Step S3: Place the next pipe section on the rolling pipe support using the guide rod and welding platform, and push it along the rolling pipe support to make the ends of the two pipe sections align and contact. Then weld the two pipe sections together on the welding platform. Then push the welded pipe section to the welding position using the rolling pipe support. Repeat step S3 until the welding of the entire pipeline in this layer is completed. Step S4: Weld pipe clamps to both sides of the horizontal radial direction of the entire welded pipe, and insert the limiting rods, which are fixedly connected to the pipe clamps, into the limiting holes to complete the installation. Specifically, the dimensions of the limiting hole and the limiting rod are designed according to the maximum allowable axial displacement and maximum radial displacement of the pipeline as required by the design. The difference between the axial dimension of the limiting hole and the limiting rod in the pipeline is twice the maximum axial displacement, and the difference between the radial dimension of the limiting hole and the limiting rod in the pipeline is twice the maximum radial displacement.

[0018] Optionally, the pipe section is a straight pipe section with a spacing smaller than that between the columns of the steel pipe gallery.

[0019] The steel structure pipe gallery pipe installation device of the present invention has the following beneficial effects: (1) The design of the rolling pipe support overturns the static support mode of the traditional sliding pipe support. Its base is welded and fixed to the crossbeam of the steel pipe gallery. The integrated conveying rollers convert the sliding friction during pipe displacement into rolling friction, reducing the displacement resistance. The ton-level pipe can be smoothly moved on the crossbeam by manpower, completely eliminating the inefficient mode of relying on lifting equipment for reciprocating hoisting. (2) The collaborative design of the welding platform and the guide rod creates a three-dimensional working space. The crane accurately lifts short pipe sections with adjustable column spacing to each welding platform through the adjustable guide rod. Workers complete the horizontal docking and circumferential welding of multiple pipe sections in a stable platform environment, transforming high-altitude suspended welding into ground-level stable operation, while avoiding the positioning deviation problem when docking in the air. This segmented lifting and rolling splicing process mode can directly complete the on-site welding of ultra-long pipe sections on the platform.

[0020] (3) When the pipe length does not match the column spacing, the short pipe section can be pushed and spliced ​​on the platform segment by segment through the dynamic transmission function of the rolling pipe support. This solves the problem of space obstruction for long pipes entering the corridor and eliminates the risk of short pipe support deficiency. The layered welding platform allows pipes at different elevations to be constructed simultaneously. Each working surface can independently carry out hoisting, welding and relocation operations, which improves the utilization rate of the pipe corridor space and is especially suitable for complex scenarios.

[0021] (4) The combination of the limiting rod and the limiting hole can control the displacement of the pipeline due to thermal expansion and contraction within the design allowable range. After the pipeline is put into operation, compared with the instability of the traditional sliding pipe support which relies on manual calibration, the limiting structure of the present invention can be fixed by welding during the construction stage, reducing the safety hazards such as pipeline falling and tilting from the source. It is especially suitable for pipeline installation under complex working conditions, and greatly improves the long-term safety of the pipe gallery operation.

[0022] (5) The layered arrangement of the guide rod and welding platform in this invention allows mechanical hoisting equipment to transport pipes to different layers. Each working surface can be independently transported and welded, which greatly improves the utilization rate of three-dimensional space and is especially suitable for pipe corridors in industrial parks with high density and multiple pipelines.

[0026] This invention proposes a pipe installation device for steel structure pipe racks, aiming to provide a convenient and rapid installation method for rolling pipe supports and pipe transportation, thus solving the problem of difficult pipe installation within the rack. A straight pipe section smaller than the spacing between the rack's columns is selected. Mechanical hoisting equipment is used to lift the straight pipe section onto a guide rod on the rack's welding platform. The pipe is then rolled onto the welding platform and placed on a pre-installed rolling pipe support. Multiple straight pipe sections are manually welded on the welding platform, and the rolling pipe support pushes the pipe to the designated position. Finally, a limiting rod is installed on the pipe, and the rolling pipe support replaces the traditional sliding pipe support. This invention significantly improves the speed of pipe installation within the rack, eliminates the need for reciprocating transport operations, reduces difficulties in aerial welding of pipe sections, and alleviates pipe support installation problems, thus possessing extremely important engineering significance.

[0027] Terminology Explanation: Rolling pipe support: An innovative support and transportation component integrating pipe clamps, limit rods, limit holes, support frames, bases, and conveyor rollers. The base is welded and fixed to the crossbeam of the steel pipe gallery, which can convert the sliding friction during pipe relocation into rolling friction. It has both pipeline transportation and long-term support functions, replacing the traditional static sliding pipe support.

[0028] Welding platform: A stable working platform arranged in layers within the pipe gallery, used for pipe segment connection and circumferential welding. With the help of guide rods, it enables precise pipe entry into the gallery, transforming high-altitude suspended welding into ground-level stable operation.

[0029] Guide rod: An adjustable guide component connected to the outside of the welding platform, used by cranes to smoothly transport pipes to each welding platform, reducing the difficulty of adjusting the posture of pipes when entering the corridor.

[0030] Limiting rod / limiting hole: The displacement control structure of the rolling pipe support. The limiting rod is welded and fixed to the pipe clamp, and the bottom extends into the limiting hole. The size is designed according to the allowable thermal expansion and contraction displacement of the pipe to ensure that the pipe displacement is within the design range.

[0031] The steel structure pipe gallery pipe installation device in this embodiment, such as Figure 1 , Figure 2 As shown, the system includes multiple rolling pipe supports 2, which are fixedly connected at intervals to multiple crossbeams of the steel structure pipe rack along its length, for moving pipes to a set position along the length of the steel structure pipe rack; multiple welding platforms 3, which are set at certain intervals along the length of the steel structure pipe rack, for welding operations between pipes; guide rods 4, for guiding pipes to fall onto the welding platforms 3 and then onto the rolling pipe supports 2; and a limiting structure for limiting the axial and radial deformation of the pipes. The rolling pipe supports 2 include limiting rods 6, limiting holes 7, columns 8, bases 9, conveying rollers 12, and pipe clamps 13.

[0032] like Figure 3 , Figure 5 As shown, the rolling tube support 2 is mounted on the upper end face of the crossbeam of the steel pipe gallery 10 via the base 9. The base 9 can be mounted on the upper end face of the crossbeam by welding. However, it is also possible to fix the base 9 to the upper end face of the steel pipe gallery 10 by bolts. For example, multiple threaded holes can be machined on the crossbeam of the steel pipe gallery 10, and multiple through holes can be machined on the base 9. Multiple mounting bolts can be screwed into the threaded holes through the through holes to fix the base 9 to the steel pipe gallery, thus ensuring that the rolling tube support 2 has a stable base.

[0033] For rectangular steel pipe gallery beams, the base can be easily placed directly on its upper surface and welded to the beam around its perimeter. For circular steel pipe gallery beams, a base with the same curvature as the circular surface can be used. The base's curved surface mates with the curved surface of the beam before welding, ensuring a stable installation. Alternatively, a flat base can be used, with multiple supporting ribs welded between the base and the beam to further stabilize the base.

[0034] A support frame is fixedly connected to the upper end of the base 9. The support frame includes at least two columns 8 spaced apart. To stabilize the support pipe, a reinforcing plate can be connected between the columns. The two ends of the reinforcing plate are welded to the columns.

[0035] A pair of conveyor rollers 12 are connected between the column 8 and the base 9. The rollers 12 are inclined between the column 8 and the base 9 with their upper ends facing away from each other. Specifically, the bottom end of the roller shaft of one conveyor roller 12 is fixedly connected to the base 9, and the upper end of the roller shaft is inclined to the left and fixedly connected to the column 8. The bottom end of the roller shaft of the other conveyor roller 12 is also fixedly connected to the base 9, and the upper end of the roller shaft is inclined to the right and fixedly connected to the column 8. The rollers and roller shafts can rotate relative to each other, thus forming a certain angle between the pair of conveyor rollers 12. This angle is used to place the pipe 1. When the pipe is pushed to move along the length of the steel pipe gallery, the rotation of the rollers allows the pipe to be easily moved into place.

[0036] It should be noted that the conveyor roller 12 may not require a drive mechanism; the pipe 1 can be moved on the conveyor roller by manual pushing. Due to the rotation of the conveyor roller, the pipe can be easily pushed to the set position. This application also does not exclude the possibility of using a drive motor to drive the conveyor roller 12. For example, the output shaft of the drive motor can be connected to the upper end of the roller shaft of the conveyor roller, and the housing of the drive motor can be fixedly connected to the column 8. The bottom end of the roller shaft of the conveyor roller can be mounted on the base 9 through a bearing. The two drive motors drive the roller shaft to rotate synchronously, and the roller and the roller shaft do not rotate relative to each other. Thus, the roller shaft drives the roller 12 to rotate.

[0037] Compared to traditional technologies, the application of the rolling pipe support in this invention transforms pipeline transportation from "reciprocating hoisting" to "linear rolling." The rolling pipe support can transport pipelines quickly and stably without compromising the stability and safety of the steel pipe gallery structure, while reducing the difficulty of pipe support installation and solving the problem of reciprocating operation of transportation vehicles.

[0038] Alternatively, other transmission mechanisms can be used to make the two transmission rollers rotate synchronously, such as... Figure 4 As shown, a drive motor drives one conveyor roller to rotate, and a bevel gear in the middle drives the other conveyor roller to rotate. Specifically, the output shaft of one drive motor is connected to the upper end of the roller shaft of the conveyor roller, and the housing of the drive motor is fixedly connected to the column 8. The bottom end of the roller shaft of the conveyor roller can be mounted on the base 9 via a bearing. Furthermore, a first bevel gear 121 is integrally connected to the roller shaft of the conveyor roller, and the first bevel gear 121 can be integrally formed with the roller shaft. A second bevel gear 122 and a first straight gear 125 are also installed on the base between the two conveyor rollers. The second bevel gear 122 and the first straight gear 125 are mounted on the same gear shaft. The bottom end of the gear shaft is mounted on the base via a bearing, and the upper end of the gear shaft is mounted on a bearing bracket 9 (not shown) fixedly connected to the base 9 via a bearing. A third bevel gear 123 and a second spur gear 126 are also mounted on the base between the two conveyor rollers. The third bevel gear 123 and the second spur gear 126 are mounted on the same gear shaft. The bottom end of the gear shaft is mounted on the base via a bearing, and the upper end of the gear shaft is mounted on a bearing bracket 9 (not shown) that is fixedly connected to the base 9 via a bearing. The first bevel gear 121 meshes with the second bevel gear 122, and the third bevel gear 123 meshes with the fourth bevel gear 124, thereby transmitting the rotational motion of one conveyor roller to the other conveyor roller, so that the two conveyor rollers rotate together in the conveying pipe.

[0039] Of course, from a cost perspective, this method of using drive motors is expensive and not suitable for widespread use. It is only applicable to steel pipe gallery construction where it is difficult to push the pipes manually. For example, if the steel pipe gallery has a certain slope and it is difficult to push the pipes along the slope, then several roller pipe supports 2 with drive motors can be used.

[0040] Multiple rolling pipe supports 2 are installed at intervals along the length of the steel pipe gallery on the crossbeams of the steel pipe gallery. For example, one rolling pipe support 2 can be installed on each crossbeam of the steel pipe gallery to support the pipe 1 to be installed. The pipe can be moved to a set position on the conveyor rollers by manual pushing.

[0041] Welding platforms 3 are installed at regular intervals along the length of the steel structure pipe rack. The height of the welding platform is equal to or slightly lower than the lowest point of the pipe 1 supported by the rolling pipe supports 2. For example, the welding platform can be at the same height as the top surface of the base 9, so as not to affect the transfer of pipes above the welding platform. The welding platform is used for welding the ends of two pipes 1. After the first pipe is placed on multiple rolling pipe supports 2 on one side of the welding platform by mechanical hoisting equipment, the pipe 1 is pushed to move along the length of the steel pipe rack, keeping its end above the welding platform. Then, the mechanical hoisting equipment lifts the second pipe and places it on multiple rolling pipe supports 2 on the other side of the welding platform. The pipe is then pushed along the length of the steel pipe rack to connect with the end of the aforementioned pipe, and then welding can be performed on the welding platform. After the two pipes are welded together, the pipe is pushed to one side of the welding platform, and then a third pipe is hoisted onto multiple rolling pipe supports 2 on the other side of the welding platform. The welding of the second and third pipes continues, thus completing the welding of multiple pipes.

[0042] The guide rod 4 is inclinedly connected to the outer side of the welding platform in the width direction, used to smoothly transport pipes hoisted by mechanical lifting equipment to the welding platform, reducing the difficulty of posture adjustment when the pipes enter the corridor. Specifically, it gradually decreases towards the rectangular shape of the welding platform, and the guide rod 4 can be inclinedly installed on the welding platform 3 via a mounting plate 41. For example... Figure 6 As shown, a mounting plate 41 is fixedly connected to the upper end of the welding platform 3. The mounting plate 41 has multiple first mounting holes 42 arranged along an arc-shaped contour, and a second mounting hole 43 located at the center of the arc-shaped contour. A guide rod 4 is installed obliquely on the outer side of the welding platform's width direction by bolts passing through the first mounting holes 42 and the second mounting holes 43. The guide rod 4 guides the pipe 1, lifted by the mechanical hoisting equipment, to roll onto the welding platform. Then, the mechanical hoisting equipment can slightly shift the pipe 1 to place it onto the rolling pipe support 2. Even with the mechanical hoisting equipment suspending the pipe, it is possible to place the pipe 1 onto at least two rolling supports 2, so that the pipe 1 can be easily pushed after being detached from the mechanical hoisting equipment.

[0043] The collaborative design of the welding platform and guide rods creates a three-dimensional working space. The crane uses the adjustable-angle guide rods to precisely lift straight pipe sections smaller than the length spacing of the steel pipe gallery columns onto the welding platform. Workers complete the horizontal docking and circumferential welding of multiple pipe sections in a stable platform environment, transforming high-altitude suspended welding into ground-level stable operation, while avoiding the positioning deviation problem when aligning in the air. This segmented lifting and rolling splicing process mode can directly complete the on-site welding of ultra-long pipe sections on the platform.

[0044] Each column 8 has a rectangular limiting hole 7 at its upper end for inserting a limiting rod 6. The lower end of each limiting rod 6 is inserted into the corresponding limiting hole 7, and a pipe clamp 13 is fixedly connected to the upper end of the limiting rod 6. The pipe clamp 13 is a cylindrical body, with one end fixedly connected to the upper end of the limiting rod 6 and the other end used to abut against the side wall of the pipe 1. The end of the pipe clamp has a certain curvature to facilitate support on the outer arc surface of the pipe. After all pipe welding is completed, the pipe clamp is welded to the contact area with the pipe, forming a welding area 11 in the contact area between the pipe side wall and the pipe clamp. This allows the pipe clamp to provide support and limit the pipe, preventing deformation of the pipe in the length and width directions.

[0045] In some embodiments, the length of the pipe clamp 13 is adjustable before it is welded to the pipe, allowing it to be supported on the sidewalls of pipes of different sizes. When the pipe diameter is large, the length of the pipe clamp is reduced; when the pipe diameter is small, the length of the pipe clamp is extended.

[0046] In some embodiments, the length of the limiting rod 6 is adjustable before welding to the pipe. Specifically, the limiting rod can be in the form of an inner and outer plug-in connection, including an outer pipe body and an inner rod body. Multiple adjustment holes are provided axially on both the outer pipe body and the inner rod body. The length of the limiting rod is adjusted by aligning the different adjustment holes on the outer pipe body and the inner rod body and screwing in a bolt. Similarly, the pipe clamp 13 can also adopt the same structure to achieve adjustable length.

[0047] The limiting structure transforms manual calibration into mechanical positioning, fundamentally reducing reliance on manual labor and the risks associated with heights, thus establishing a highly efficient and safe operation mode of "mechanical dominance with manual assistance." This technology not only significantly shortens the installation cycle and reduces construction costs, but also lays the foundation for the intelligent and digital upgrade of industrial pipeline installation through standardized pipe support design and modular construction processes. Its engineering application value lies not only in the immediate efficiency improvement, but also in providing a reliable guarantee for the long-term safe operation of steel pipe gallery structures.

[0048] Furthermore, based on the design requirements for the maximum allowable axial (i.e., along the length of the steel pipe rack) and radial displacement of the pipeline, the dimensions of the limiting holes and limiting rods are designed. Both the limiting holes and limiting rods are rectangular. The limiting rod is inserted into the center of the limiting hole. The difference in length between the limiting hole and the limiting rod is twice the maximum axial displacement, and the difference in width between the limiting hole and the limiting rod is twice the maximum radial displacement. For example, if the design requires a maximum allowable axial (i.e., along the length of the steel pipe rack) displacement of 150mm and a maximum radial displacement of 100mm, then the limiting holes and limiting rods are designed to be rectangular. The difference in length between the limiting hole and the limiting rod is 300mm, and the difference in width is 200mm. During installation, the center point of the limiting rod and the limiting hole should be aligned, and the bottom of the limiting rod needs to be fully inserted into the limiting hole to ensure that the limiting hole functions as a limiting device. Because the limiting rod is welded to the pipe clamp, and the pipe clamp is welded to the pipe, after the steel pipe gallery is put into use, the deformation of the pipe in both the length and width directions will be reflected on the limiting rod. However, since the limiting rod is inserted into the limiting hole, the movement of the limiting rod from the center of the limiting hole in the length direction is only 150mm, and the movement in the width direction is only 100mm.

[0049] According to one aspect of this application, a steel structure pipe gallery pipeline installation system is also provided, comprising multiple sets of steel structure pipe gallery pipeline installation devices. Each set is used for the installation of one layer of pipeline in the steel structure pipe gallery. The number of sets of steel structure pipe gallery pipeline installation devices corresponds to the number of pipeline layers to be installed. Each set of steel structure pipe gallery pipeline installation devices does not affect the use of others, and multiple layers of pipeline can be installed simultaneously.

[0050] According to one aspect of this application, a method for installing pipes in a steel structure pipe gallery is also provided, with reference to... Figure 1 Using the steel structure pipe gallery pipe installation device described above, the following steps are performed: Step S1: Determine the number of pipe installation devices for the steel structure pipe gallery based on the number of pipe installation layers, and install the corresponding rolling pipe supports on each crossbeam of the steel pipe gallery according to the pipe positions on each layer. For example, if a steel pipe gallery needs to install three layers of pipes, then there is a corresponding three-layer steel structure pipe gallery pipe installation device. Before installation, determine that the number of pipe installation layers is the second layer, the pipe installation interval is 60m, determine the position of the pipe entry welding platform, and install the rolling pipe support described in this application on the corresponding crossbeam according to the drawings; Step S2: For the floor where the pipe is to be installed, use mechanical hoisting equipment and guide rod 4 to send the pipe into the welding platform 3 of the corresponding floor, and then place the pipe on the rolling pipe support and push it to the required position.

[0051] For example, the mechanical hoisting equipment first places the pipe on the guide rod on the second floor, and then the pipe is manually rolled into the welding platform 3; the hoisting equipment is used to lift the pipe and place it on the rolling pipe support, and push the pipe 3m along the length of the steel pipe gallery to leave enough operating space for the second section of pipe to enter the gallery and weld. Step S3: Place the next section of pipe onto the rolling pipe support 4 using the guide rod and welding platform, aligning the ends of the two pipe sections. Then, manual welding can be performed on the welding platform 3 to weld the two pipe sections together. Finally, push the pipe to the appropriate position. Repeat step S3 until the welding of the entire pipe in this layer is completed.

[0052] Step S4: Weld pipe clamps to both sides of the horizontal radial direction of the pipe, and insert the limiting rods that are fixedly connected to the pipe clamps into the limiting holes to complete the installation.

[0053] Specifically, after the pipeline is moved to the designated position, according to the design requirements, the maximum allowable axial displacement of the pipeline is 150mm, and the maximum allowable axial displacement of the pipeline is 100mm. Therefore, during installation, the dimension of the limiting rod in the axial direction of the pipeline should be 300mm smaller than the opening of the limiting hole, and the dimension of the limiting rod in the radial direction of the pipeline should be 200mm smaller than the opening of the limiting hole. Furthermore, the center points of both should be aligned during installation. The limiting rod is welded to the pipe clamp, and the pipe clamp is welded to the pipeline. The bottom of the limiting rod needs to be inserted deep into the limiting hole of the rolling pipe support to ensure that the limiting hole functions as a limiting device.

[0054] For a conventional three-story pipe gallery with a column spacing of 9m, if a DN500 pipe needs to be installed on the second floor of the gallery, the conventional hoisting method is to select a 12m long straight pipe section and use methods such as lifting, pulling, and dragging to send the straight pipe section into the gallery from the side. This is not only difficult to operate and inefficient, but also easily affects the safety of the gallery. Using the steel structure pipe gallery installation device of this application, a welding platform is set up every 60m, and a guide rod 4 is installed outside the welding platform. A 6m long straight pipe section can be selected, enabling rapid pipe installation.

[0055] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
