Background Technology

[0002] In traditional large-scale industrial plant workshop column-based piping construction, cranes and manual labor are typically used for pipe hoisting, connection, and welding. This method has several limitations: firstly, the construction cycle is long, and the efficiency of crane scheduling and manual labor coordination is low; secondly, renting large cranes is expensive, increasing construction costs; thirdly, high-altitude operations and hoisting processes pose significant safety risks, with a high risk of falls or collisions; and fourthly, the high friction during pipe movement and connection makes adjustments difficult, affecting welding quality and installation accuracy. Furthermore, traditional methods are highly dependent on site space and equipment, lacking adaptability and making efficient operation difficult in complex or confined factory environments. Therefore, there is an urgent need for a specialized device and method that can reduce construction costs, improve work efficiency, ensure construction safety, and is suitable for the rapid installation of column-based piping.

[0035] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0036] This embodiment proposes a workshop column-type pipe installation device, such as... Figure 1-2 As shown, the system includes a traction unit for providing horizontal or vertical movement to the pipeline 1, a temporary platform 5 for welding operations on the pipeline 1, a support unit for supporting the pipeline 1 and reducing its movement and rotational friction, and a pulley system 8 for reducing friction during horizontal traction by the large winch 3. The traction unit includes a large winch 3 and a small winch 6 installed at both ends of the plant. Through the coordinated traction of the large winch 3 and the small winch 6, the pipeline 1 is hoisted onto the temporary platform 5. The support unit 2 provides mobile support for the pipeline 1 and assists in adjusting its position. Then, the pipeline 1 is assembled and welded section by section on the temporary platform 5 until all pipeline 1 is installed.

[0037] Several pairs of columns 4 are arranged side-by-side within the factory building. Each pair of columns 4 has two columns, and several horizontal beams are welded between the two columns in each pair of columns 4. Preferably, the beams are square steel, with both ends fixedly welded to the columns, and at least two beams are provided along the height of the columns. To ensure the stability and consistency of the pipeline 1 in the horizontal direction of movement, the beam used to install the support unit on each pair of columns 4 must be at the exact same height; this means that the support points between all pairs of columns are horizontally aligned, forming a continuous, flat virtual track running through the entire factory building.

[0038] Support unit 2 is installed on the crossbeam at a uniform height, so that there will be no height difference when pipe 1 moves and rolls on it, and it can smoothly slide from one column to the next. Taking the direction of pipe 1's forward movement as the reference, the columns from the initial feeding position to the last pair of columns 4 are successively called the first row, the second row, the third row... and the last row.

[0039] The large winch 3 is positioned on the outside of the last row of columns 4, near one end of the pulley block 8. It is connected to the pipe 1 via a steel wire rope 7 and is primarily used to provide horizontal traction power for the pipe 1. The large winch 3 ensures that the central axis of the pipe 1 remains straight during horizontal traction, greatly facilitating subsequent assembly and welding. It enables the pipe 1 to be installed quickly, smoothly, and in a straight line, making the horizontal movement of the pipe 1 along the column direction more efficient and precise.

[0040] The pulley block 8 is a simple guiding mechanism composed of multiple pulleys, arranged side by side along the height of the column and fixed to the crossbeam. The pulley block 8 is a common structure in this field, and detailed drawings are omitted here. The pulley block 8 is installed on the crossbeam of the last row of columns 4 in the factory building, extending horizontally outwards. The pulley block 8 is mainly used to change the traction direction of the wire rope 7 and distribute the force, thereby significantly reducing the friction and traction resistance of the large winch 3 when horizontally dragging the pipe 1, allowing the pipe 1 to move into position more effortlessly and smoothly.

[0041] The small winch 6 is installed at the end furthest from the large winch 3, between the first row of columns 4 and the second row of columns 4. It suspends the guide rope 9 through the hanging point 11 installed on the roof beam 10 of the factory building to achieve its guiding function. The small winch 6 is mainly used to provide traction power for the vertical hoisting of the pipeline 1 and to control the vertical height position of the pipeline 1 through the hoisting of the rope 9.

[0042] The small winch 6 is responsible for vertically hoisting pipe 1 from the ground to the temporary platform 5 used for welding pipe assembly. It is the power equipment for lifting pipe 1, forming a division of labor with the horizontal pulling of the large winch 3. The hemp rope 9 is a flexible hoisting rope, which is manually pulled and used to control and stabilize the aerial posture and direction of pipe 1 during hoisting, preventing it from rotating or colliding, and ensuring that the pipe can be smoothly and accurately lowered to the designated position on the platform. The hanging point 11 is a fixed support point welded to the roof beam 10 of the factory building, used to change the direction of the hemp rope 9 on the small winch 6, forming a fixed pulley structure. The hanging point 11 is equivalent to a high-altitude guide ring, which converts the upward vertical pulling force of the small winch 6 into a forward and upward resultant force, thereby lifting pipe 1 obliquely from the ground and sending it to the temporary platform 5.

[0043] Temporary platform 5 is located near the small winch 6, positioned at the location of the second row of columns 4, and erected on the crossbeams between the columns 4. Temporary platform 5 is situated below the designed installation route of pipeline 1, serving as a receiving and working surface after pipeline 1 is hoisted. Temporary platform 5 is a detachable steel structure or scaffolding-style working platform, installed between the crossbeams of the columns 4, providing support for personnel and pipeline 1. As a safe welding work surface, temporary platform 5 provides a stable and reliable high-altitude working plane for pipeline assembly, welding, and other operations, fundamentally avoiding the dangers of traditional high-altitude suspended operations. Simultaneously, temporary platform 5 also serves as a transfer and positioning platform for pipeline 1, acting as an intermediate transition point from the hoisted state of pipeline 1 by the small winch 6 to its final installation position; pipeline 1 completes initial positioning and assembly with the preceding pipeline on this platform, preparing for the next stage of horizontal traction by the large winch 3.

[0044] like Figure 3As shown, support unit 2 is installed on the crossbeam between each pair of columns 4 to support the horizontal crossbeam of pipe 1; the height of the crossbeams used to install the support unit on all columns must be the same, thus forming a continuous, horizontal support track within the plant. Support unit 2 is a modular, detachable mechanical component, a specialized tooling that converts sliding / rotational friction into rolling friction through spherical rollers 22, and is the key hardware for achieving labor-saving and precision in the entire rapid installation method.

[0045] like Figure 4 As shown, the support unit 2 includes a main frame with a V-shaped groove 21 and several spherical rollers 22 disposed within the V-shaped groove 21. The main frame also includes a support plate 23 for fixing and welding the V-shaped groove 21. The support plate 23 is bolted to a sliding plate 24, which locks the sliding plate 24 and the main frame together onto the crossbeam. The pipe 1 is placed directly within the V-shaped groove 21 and contacts the surface of the spherical rollers.

[0046] like Figure 5 As shown, the main frame is the load-bearing skeleton of the support unit 2. The V-shaped groove 21 on it is composed of two sections of square steel joined together, and circular mounting holes for installing spherical rollers 22 are opened on its mating surface. The main frame structure is designed to be robust, used to bear the weight of the pipe 1 and transmit the force to the crossbeam.

[0047] The V-shaped slot 21 is fixedly welded to the L-shaped support plate 23. The support plate 23 includes a horizontal section and a vertical section. The V-shaped slot 21 is fixedly welded to the horizontal section by square steel. A sliding slot is provided below the horizontal section of the support plate 23 for alignment, and several mounting holes are provided on the vertical section of the support plate 23.

[0048] like Figure 6 As shown, the spherical roller 22 is the core functional component of the support unit 2. It is installed in the circular hole in the V-shaped slot 21 and can rotate freely. Its spherical outline forms point contact with the outer wall of the pipe 1.

[0049] like Figure 7 As shown, the slide plate 24 is a fixing and adjusting component of the support unit 2. It is located at the bottom of the main frame, and its two sides are provided with grooves that mate with the slots. That is, a set of dovetail platforms facing away from each other are provided on both sides of its top width to form a T-shaped groove, which is directly embedded in the slot. The structure of the slide plate 24 allows the bolts to move within the slots on the horizontal section of the support plate 23, thereby adjusting the installation position of the device within a certain range.

[0050] The slide plate 24 is also provided with several mounting holes, the mounting holes on the slide plate 24 being the same in position and number as those on the support plate 23. The support unit 2 is detachably fixed to the crossbeam by bolts passing sequentially through the mounting holes on the support plate 23, the mounting holes on the crossbeam, and the mounting holes on the slide plate 24. That is, the entire support unit 2 is securely installed on the crossbeam of the factory column 4 by bolts passing through the mounting holes on the slide plate 24.

[0051] Support unit 2 is fixed on a crossbeam at a uniform height. During the installation of pipe 1, it lays a bearing track for pipe 1, which significantly reduces the force required for pipe 1 to move horizontally and rotate circumferentially, thus making construction more convenient and improving construction efficiency.

[0052] A method for constructing pipelines in a workshop column, using the installation device described above, includes the following steps:

[0053] S1. Install a large winch 3 and a small winch 6 at both ends of the factory building, set up a temporary platform 5, and install a temporary support unit 2 for the pipeline 1 and a pulley block 8; the hemp rope 9 of the small winch 6 is suspended and guided through the hanging point 11 installed on the roof beam 10 of the factory building.

[0054] A large winch 3 is installed on the ground at one end of the factory building, and a small winch 6 is installed at the other end. A temporary platform 5 is erected on the crossbeam between the columns 4, and a temporary support unit 2 and pulley block 8 for the pipe 1 are installed. The hemp rope 9 of the small winch 6 is passed through the hanging point 11 welded to the roof beam 10.

[0055] The large winch 3 for horizontal traction and the small winch 6 for vertical hoisting are used as two main power systems, forming a coordinated operation layout to avoid interference. The temporary platform 5 provides a safe and stable working surface for high-altitude welding, a core measure to ensure construction safety. Installing the support unit 2 and pulley block 8 is similar to laying a bearing track and a labor-saving guide wheel, laying the physical foundation for the subsequent labor-saving movement of the pipeline 1. The purpose of setting the suspension point 11 is to change the direction of force on the hemp rope 9 of the small winch 6, enabling it to lift the pipeline 1 obliquely from the ground and accurately deliver it to the position of the temporary platform 5, thus acting as a guide pulley.

[0056] S2. Using a large winch 3, the pipe 1 is moved horizontally to the designed position on the support unit 2. The pipe 1 uses a pulley block 8 to reduce traction friction, and the support unit 2 provides rolling support during the movement and welding of the pipe 1.

[0057] Start the large winch 3 and use the wire rope 7 to horizontally pull the pipe 1; the pipe 1 moves on the spherical roller 22 of the support unit 2 and is guided by the pulley block 8, realizing long-distance, precise and labor-saving horizontal transportation of the pipe 1.

[0058] The large winch 3 provides the main power for the movement of pipe 1 along the axis of column 4; the spherical rollers 22 of the support unit 2 transform the sliding friction between pipe 1 and the support into rolling friction. The pulley block 8 at the end further reduces the friction of the traction wire rope 7 and plays a final guiding role, ensuring that pipe 1 is accurately positioned. The continuous rolling support formed by the support unit 2 on the crossbeam allows pipe 1 to be pulled to the design position in one go or in multiple continuous sections, improving efficiency.

[0059] S3. Use a small winch 6 to hoist pipe 1 from the ground to the temporary platform 5; use hemp ropes 9 at both ends of pipe 1 to control the hoisting direction.

[0060] The small winch 6 was started to lift the pipeline 1 from the ground to the height of the temporary platform 5; the construction workers controlled its attitude and position in the air by pulling the hemp ropes 9 attached to both ends of the pipeline. The vertical transfer of the pipeline 1 from the ground to the high-altitude work surface was completed safely and controllably.

[0061] By pulling the hemp rope 9, workers can prevent the pipe 1 from rotating or swinging in the air and can fine-tune its lowering position to ensure that the pipe 1 can be placed smoothly and accurately on the temporary platform 5 or support unit 2, thus making up for the lack of precision of simple mechanical hoisting.

[0062] S4. Perform assembly welding of pipe 1 on temporary platform 5.

[0063] Pipe 1 is supported and secured on temporary platform 5, where workers align, assemble, and weld the pipe ends, completing the final quality control process for pipe 1 connection. Temporary platform 5 provides a stable and spacious working surface for welding, allowing workers to operate safely and place tools, completely changing the dangerous conditions of traditional high-altitude or climbing welding. On the platform, pipe 1 is supported by support unit 2, whose spherical rollers 22 allow for easy, slight rotation of pipe 1, achieving perfect alignment of the pipe ends and greatly improving assembly accuracy and welding quality. After the first section of pipe 1 is welded, it can be towed away, making room for hoisting and welding the next section of pipe 1, thus enabling continuous operation.

[0064] S5. Repeat S3 to S4 until all pipes 1 are installed.

[0065] The entire process systematically solves the problems of low efficiency, high cost, high risk, and poor accuracy in traditional methods by dividing the work of large and small winches, by reducing friction in key position support units 2 and pulley blocks 8, and by ensuring safe operation through temporary platform 5.

[0066] This application discloses a workshop column-mounted pipe installation device and construction method. Through a traction unit, support unit, and pulley system, it achieves rapid and stable installation of the column-mounted pipes, significantly improving construction efficiency and shortening the construction period. By reducing reliance on large cranes, it lowers equipment rental and labor costs. The rolling components and adjustable design of the support unit make pipe movement and rotation more labor-saving and precise, improving welding quality and installation accuracy. Welding operations can be performed on a temporary platform, enhancing construction safety. This installation device is simple in structure, flexible in assembly and disassembly, reusable, and widely applicable. It provides reliable technical support and experience for similar projects, demonstrating significant economic benefits and practical engineering value.

[0067] The embodiments of this application have been described in detail above. These descriptions are merely preferred embodiments and should not be construed as limiting the scope of this application. All equivalent variations and modifications made within the scope of this application should still fall within the patent coverage of this application.
