Description

Technical Field

[0001] This invention belongs to the technical field of assembly tools for operational transportation parts, specifically relating to an adjustable steel pipe frame standardized processing system and its usage method. Background Technology

[0002] Currently, steel pipe frames such as scaffolding and towers used in building construction are mostly connected by welding or bolts. Welded steel pipe frames require remanufacturing for reuse, resulting in poor versatility and waste. While bolted steel pipe frames can be reused after disassembly, the concentricity of the flanges at both ends is difficult to control during processing, causing instability due to misalignment of the overall axis, potentially leading to safety accidents. Furthermore, significant deviations in the length of the steel pipes used in the frame cause difficulties in connecting diagonal braces, horizontal braces, and other connecting systems to the steel pipe frame. To address these issues, the following improved technical solutions are proposed. Summary of the Invention

[0004] The technical solution adopted in this invention is as follows: An adjustable steel pipe frame standardized processing system, comprising a platform, with a fixed-end flange fixing device vertically fixed at one end of the platform and a sliding-end flange fixing device vertically fixed at the other end of the platform. The fixed-end flange fixing device and the sliding-end flange fixing device are used to fix the steel pipe flange respectively. A pair of steel pipe support height adjustment devices are provided in the middle of the platform. The steel pipe support height adjustment devices horizontally support the steel pipe body and are used to adjust the horizontal height of the steel pipe body. The sliding-end flange fixing device is locked in position by a sliding-end locking device. The fixed-end flange fixing device and the sliding-end flange fixing device are concentrically arranged and each is equipped with an electromagnet, which is used to magnetically fix the steel pipe flange. The fixed-end flange fixing device and the sliding-end flange fixing device are also provided with flange positioning devices, which are used to adjust the position of the steel pipe flange. The fixed-end flange fixing device and the sliding-end flange fixing device are also provided with a center and a cross scale, and the platform is provided with a horizontal scale.

[0005] In the above technical solution, the platform is further composed of several parallel and identical I-beams arranged side by side. The I-beams are equipped with slide rails, and the sliding end flange fixing device is adapted to slide horizontally with the slide rails.

[0006] In the above technical solution, the fixed end flange fixing device and the sliding end flange fixing device each have an L-shaped plate. The back of the L-shaped plate is provided with stiffening ribs of a right-angled triangular structure. The horizontal plate of the L-shaped plate is fixed to the platform, and the vertical plate of the L-shaped plate is used to fix the steel pipe flange.

[0007] In the above technical solution, further: each steel pipe support height adjustment device consists of two synchronous jacks and a steel pipe bracket; both jacks are vertically fixed on the ground, and the vertically upward execution end of the jacks is fixed to the bottom of the vertically set steel pipe bracket. The top of the steel pipe bracket is provided with a vertical steel plate, and the center of the top of the vertical steel plate is provided with an arc groove, which is used to support the steel pipe body.

[0008] In the above technical solution, the sliding end clamping device further comprises a clamp and a clamp fastener; the clamp is used to clamp the bottom of the sliding end flange fixing device and the platform, and the clamp fastener is used to lock the position of the sliding end flange fixing device relative to the platform.

[0009] In the above technical solution, further: the flange positioning device includes a "star-shaped" baseline, and the position of the steel pipe flange is positioned by the "star-shaped" baseline.

[0010] This invention also claims protection for a method of using an adjustable steel pipe frame standardized processing system, wherein the system is any of the adjustable steel pipe frame standardized processing systems described in the invention, and the method of using the adjustable steel pipe frame standardized processing system includes the following steps:

[0011] S1. Place the CNC-cut and drilled steel pipe flange on the flange positioning device. Adjust the steel pipe flange into position according to the outer diameter of the steel pipe flange and the center, cross scale, and "star" shaped reference line. Use an electromagnet to attract and fix the steel pipe flange to the fixed end flange fixing device and the sliding end flange fixing device.

[0012] S2. Open the sliding end clamping device of the sliding end flange fixing device, and push the sliding end flange fixing device so that the distance between the inner surface of the sliding end flange fixing device and the inner surface of the fixed end flange fixing device is greater than the total length of the steel pipe body.

[0013] S3. Place the steel pipe body on the steel pipe support and height adjustment device, so that one end of the steel pipe body is in close contact with the steel pipe flange on the fixed end flange fixing device, and use a jack to adjust the height of the steel pipe body so that the center line of the steel pipe body is concentric with the center lines of the steel pipe flanges on both sides.

[0014] S4.

Detailed Implementation

[0030] The following will refer to the appendices in the embodiments of the present invention. Figure 1-9 The technical solutions in the embodiments of the present invention are clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0031] (like Figures 1 to 3 (As shown) An adjustable steel pipe frame standardized processing system includes a platform 1. A fixed-end flange fixing device 2 is vertically fixed at one end of the platform 1, and a sliding-end flange fixing device 3 is slidably and vertically installed at the other end of the platform 1. The fixed-end flange fixing device 2 and the sliding-end flange fixing device 3 are used to fix steel pipe flanges 13. A pair of steel pipe support height adjustment devices 4 are provided in the middle of the platform 1. The steel pipe support height adjustment devices 4 horizontally support the steel pipe body 12 and are used to adjust the horizontal height of the steel pipe body 12. The sliding-end flange fixing device 3 is locked in position by a sliding-end locking device 5. The fixed-end flange fixing device 2 and the sliding-end flange fixing device 3 are concentrically arranged and each is equipped with an electromagnet 6, which is used to magnetically fix the steel pipe flanges 13. The fixed-end flange fixing device 2 and the sliding-end flange fixing device 3 are also respectively equipped with flange positioning devices 7, which are used to adjust the position of the steel pipe flanges 13. The fixed end flange fixing device 2 and the sliding end flange fixing device 3 are also provided with a center and a cross scale 8, and the platform 1 is provided with a horizontal scale.

[0032] It should be noted that the system of this invention has the advantages of high-precision positioning, flexible adjustment, stable support, efficient operation, wide applicability, standardized and modular design, and safety and reliability. Specifically, the fixed-end flange fixing device 2 and the sliding-end flange fixing device 3 are concentrically arranged and equipped with a center and cross scale 8, which can precisely control the position of the steel pipe flange 13, ensuring processing accuracy. Simultaneously, the flange positioning device 7 further enhances the accuracy of position adjustment. The sliding-end flange fixing device 3 can slide and is locked in position by the sliding-end locking device 5, allowing the system to adapt to the processing needs of steel pipes of different lengths. Furthermore, the steel pipe support height adjustment device 4 can adjust the horizontal height of the steel pipe body 12, increasing the system's flexibility and adaptability. The steel pipe support height adjustment device 4 not only horizontally supports the steel pipe body 12 but also adjusts its height, ensuring the stability of the steel pipe during processing, which is crucial for ensuring processing quality and improving production efficiency. The electromagnet 6 enables the steel pipe flange 13 to be quickly and securely magnetically fixed, simplifying the operation process and improving work efficiency. Simultaneously, the standardized design of the entire system makes operation even simpler and faster. This system is suitable for processing steel pipes of different diameters and lengths, possessing wide applicability; it can be applied for standardized processing in large-scale construction, bridge engineering, and other fields requiring steel pipe structures. The entire system adopts a standardized and modular design, facilitating installation, disassembly, and transportation. This not only reduces operating costs but also improves the system's maintainability and scalability. Each component in the system is carefully designed and manufactured to ensure it can withstand various forces and vibrations during processing, guaranteeing operator safety. Furthermore, the magnetic fixing method of the electromagnet 6 avoids the loosening or detachment problems that may occur with traditional clamps, further enhancing system safety.

[0033] In the above embodiments, the platform 1 is further composed of several parallel and identical I-beams arranged side by side, each I-beam having a slide rail 9, and the sliding end flange fixing device 3 is horizontally adapted to the slide rail 9.

[0034] It should be noted that I-beams possess high bending stiffness and load-bearing capacity. Their cross-sectional shape, with wide flanges and thin webs, effectively distributes vertical and horizontal loads, ensuring that platform 1 is not easily deformed during long-term use. By arranging multiple I-beams side-by-side at intervals, the overall weight of platform 1 is reduced, material costs are lowered through the interval layout, and sufficient structural strength is maintained. The interval design also facilitates subsequent maintenance and repair. The slide rail 9 and the sliding end flange fixing device 3 are horizontally compatible, achieving stepless adjustment. The sliding end flange fixing device 3 can move precisely along the slide rail 9 to adapt to the processing requirements of steel pipes of different lengths, eliminating the need for frequent replacement of fixing devices or adjustment of the platform structure. The slide rail 9 is typically designed with a scale to achieve millimeter-level positioning accuracy, ensuring the alignment of the steel pipe flange during processing and reducing welding or connection errors. Using structurally identical I-beams as the platform foundation facilitates mass production and standardized management. If an I-beam is damaged, it can be quickly replaced, reducing maintenance costs. The slide rail 9 can be pre-installed as an independent module on the I-beam, simplifying the assembly process of platform 1 and improving production efficiency. The spaced arrangement of the I-beams reduces material usage, making the platform lighter than a solid platform and lowering transportation and installation costs. I-beams are a common type of steel with low procurement costs and easy processing, further reducing the overall system cost. The design of the slide rail 9 allows platform 1 to be adapted to steel pipes of different diameters; only the position of the sliding end flange fixing device 3 needs to be adjusted, without modifying the structure of platform 1. The wide flanges and spaced arrangement of the I-beams enhance the anti-tipping ability of platform 1, ensuring its stability and preventing overturning during movement of the sliding end flange fixing device 3. The sliding design of the sliding end flange fixing device 3 reduces the difficulty of manual adjustment; operators can easily push the device to the designated position and quickly lock it using the locking device, improving work efficiency. Gradient markings can be installed next to the slide rail 9, allowing operators to achieve precise positioning without additional measuring tools, reducing human error.

[0035] In the above embodiments, further: the fixed end flange fixing device 2 and the sliding end flange fixing device 3 each have an L-shaped plate body, the back of the L-shaped plate body is provided with a stiffening rib with a right-angled triangular structure, the horizontal plate body of the L-shaped plate body is fixed to the platform 1, and the vertical plate body of the L-shaped plate body is used to fix the steel pipe flange 13.

[0036] It should be noted that the L-shaped plate is fixed to platform 1 via a horizontal plate, while the vertical plate is perpendicular to the platform, forming a natural right-angle support structure. This design effectively resists bending moments and shear forces, preventing deformation of the flange fixing device during processing from affecting the positioning accuracy of the steel pipe flange. The two right-angled sides of the right-angled triangular stiffening rib are fixed to the horizontal and vertical plates of the L-shaped plate, forming a rigid triangular structure. A triangle is the most stable shape in geometry, capable of distributing and transferring loads, significantly enhancing the torsional and bending resistance of the L-shaped plate, ensuring that the flange fixing device is not prone to loosening or deformation during long-term use. During processing, the steel pipe flange 13 is subjected to dynamic loads such as welding stress and vibration. The combined design of the L-shaped plate and stiffening ribs allows the load to be transferred to platform 1 via the horizontal plate, and then distributed to the vertical plate via the stiffening ribs, forming a multi-path load transfer mechanism and avoiding localized stress concentration. The rigid support of the right-angled triangular stiffeners reduces the minute deformation of the L-shaped plate under dynamic loads, lowers the risk of material fatigue damage, and extends the service life of the flange fixing device. Both the L-shaped plate and the stiffeners can be made of standardized steel (such as angle steel and flat steel), facilitating mass production and quality control. The horizontal plate of the L-shaped plate is fixed to platform 1, and the vertical plate is perpendicular to platform 1, forming a natural right-angle reference plane. This allows for quick positioning of the steel pipe flange without complex adjustments during installation, improving installation efficiency.

[0037] (like Figure 4 As shown in the above embodiment, each of the steel pipe support height adjustment devices 4 is further composed of two synchronous jacks 10 and a steel pipe bracket 11; both jacks 10 are vertically fixed on the ground, and the vertically upward execution end of the jacks 10 is fixed to the bottom of the vertically set steel pipe bracket 11. The top of the steel pipe bracket 11 is provided with a vertical steel plate 1101, and the center of the top of the vertical steel plate 1101 is provided with an arc groove 1102, which is used to support the steel pipe body 12.

[0038] It should be noted that the two jacks 10 operate synchronously to ensure that the steel pipe bracket 11 remains horizontal during lifting and lowering, preventing the steel pipe from tilting or the bracket from deforming due to uneven force on one side. The synchronous control technology allows for millimeter-level height adjustment, meeting the requirements of high-precision processing. The continuous lifting characteristic of the jacks 10 allows for arbitrary adjustment of the steel pipe height, adapting to the processing needs of steel pipes of different diameters. The two jacks 10 provide dual support points, distributing the gravity load of the steel pipe body 12, reducing stress concentration at single points, and lowering the risk of bracket deformation or damage. The arc-shaped groove 1102 at the top of the vertical steel plate 1101 completely fits the outer wall of the steel pipe body 12, increasing the contact area, dispersing local pressure, and preventing the steel pipe from slipping or rolling due to vibration or external forces during processing. The wrapping support design of the arc-shaped groove 1102, combined with the synchronous control of the two jacks, forms a stable triangular support system, effectively resisting lateral forces during processing and ensuring that the steel pipe remains in a horizontal and stable state. The steel pipe bracket 11 adopts a combination structure of vertical steel plate 1101 and arc groove 1102. The thickness of the steel plate and the curvature of the groove have been optimized through mechanical calculations, which can withstand the weight of large-tonnage steel pipes and the dynamic loads generated during processing, and are not easily deformed after long-term use. The industrial-grade jack 10 has overload protection and self-locking function, which can maintain the current height in the event of power failure or malfunction, preventing the steel pipe from suddenly falling and ensuring operational safety. By adjusting the stroke of the jack 10 or replacing the arc groove 1102 with different curvatures, it can be adapted to steel pipe bodies 12 of different diameters without the need for customized special support devices, reducing equipment costs. Operators can adjust the height of two jacks 10 simultaneously through the control panel or remote control, eliminating the need for manual adjustment one by one, shortening preparation time and improving production efficiency. Scale markings can be set on the jacks or brackets to facilitate operators to quickly read the current height and reduce measurement errors. The jack 10 and the steel pipe bracket 11 are independent modules, which can be replaced separately when damaged, reducing maintenance costs.

[0039] In the above embodiments, the sliding end clamping device 5 is further composed of a clamp and a clamp fastener; the clamp is used to clamp the bottom of the sliding end flange fixing device 3 and the platform 1, and the clamp fastener is used to lock the position of the sliding end flange fixing device 3 relative to the platform 1.

[0040] It should be noted that the clamp simultaneously holds the bottom of the sliding end flange fixing device 3 and the platform 1, forming a double fixing point. This effectively eliminates the risk of offset from single-point fixing and ensures accurate positioning of the flange fixing device in both horizontal and vertical directions. The clamp fasteners (such as bolts, nuts, or quick-release clamps) mechanically press the clamp and the clamped part together, forming a rigid connection that resists vibration, impact, and thermal deformation during processing, maintaining the stability of the flange fixing device. The clamp and fasteners are independent modules. During installation, simply insert the clamp into the corresponding positions on the bottom of the sliding end flange fixing device 3 and the platform 1, and then lock it with the fasteners. No complex tools or professional training are required, and operators can quickly complete the positioning adjustment. If quick-release clamps or hand-tightened bolts are used as fasteners, one-handed operation is possible. When adjusting the position of the flange fixing device, it is not necessary to completely disassemble the clamp; simply loosen the fasteners for sliding adjustment, significantly reducing downtime. The opening size and shape of the clamp can be customized according to the specifications of the bottom of the sliding end flange fixing device 3 and the platform 1. This design is not only suitable for steel pipe frame processing, but can also be extended to other machining scenarios that require sliding positioning (such as pipe welding, mold adjustment, etc.), simply by replacing the clamp with the corresponding specifications. The clamp and fasteners can be standardized and mass-produced, reducing unit cost, and are highly interchangeable, facilitating maintenance and replacement. The fasteners can be equipped with anti-loosening spring washers to prevent the clamp from loosening due to vibration during processing, ensuring the stability of the flange fixing device position. The rigid connection of the clamp can limit the displacement range of the sliding end flange fixing device 3, preventing the flange fixing device from detaching from the platform due to misoperation or system failure, ensuring operational safety. The contact surface between the clamp and the clamped part can be sprayed with a wear-resistant coating such as polytetrafluoroethylene to reduce wear caused by long-term friction and extend service life. If the clamp or fastener is damaged, the corresponding part can be replaced individually without replacing the entire clamping device, reducing maintenance costs.

[0041] In the above embodiments, the flange positioning device 7 further includes a "star-shaped" baseline, and the position of the steel pipe flange is located by means of the "star-shaped" baseline.

[0042] This invention also claims protection for a method of using an adjustable steel pipe frame standardized processing system, wherein the system is any of the adjustable steel pipe frame standardized processing systems described in any claim, and the method of using the adjustable steel pipe frame standardized processing system includes the following steps:

[0043] (like Figure 5 (As shown) S1. Place the CNC-cut and drilled steel pipe flange 13 on the flange positioning device 7. Adjust the steel pipe flange 13 into position according to the outer diameter of the steel pipe flange 13 and the center, cross scale 8, and "rice-shaped" baseline. Use electromagnet 6 to attract and fix the steel pipe flange 13 to the fixed end flange fixing device 2 and the sliding end flange fixing device 3.

[0044] (like Figure 6 (As shown) S2, open the sliding end clamping device 5 of the sliding end flange fixing device 3, push the sliding end flange fixing device 3, so that the distance between the inner surface of the sliding end flange fixing device 3 and the inner surface of the fixed end flange fixing device 2 is greater than the total length of the steel pipe body 12.

[0045] (like Figure 7 (As shown) S3. Place the steel pipe body 12 on the steel pipe support height adjustment device 4, so that one end of the steel pipe body 12 is closely attached to the steel pipe flange 13 on the fixed end flange fixing device 2, and use the jack 10 to adjust the height of the steel pipe body 12 so that the center line of the steel pipe body 12 is concentric and collinear with the center lines of the two steel pipe flanges 13.

[0046] (like Figure 8 (As shown) S4, slide the sliding end flange fixing device 3 inward so that the steel pipe flange 13 on the sliding end flange fixing device 3 is tightly attached to the other end of the steel pipe body 12, and then lock the sliding end clamping device 5; turn off the electromagnet 6, and weld the steel pipe flanges 13 at both ends of the steel pipe body 12 to complete the welding of the steel pipe frame.

[0047] (like Figure 9 (As shown) S5, open the sliding end clamping device 5, slide the sliding end flange fixing device 3 outward, and take out the welded steel pipe frame.

[0048] It should be noted that the method of this invention, through a systematic and modular operation process combined with high-precision positioning and dynamic adjustment technology, significantly improves the efficiency, accuracy, and safety of steel pipe frame processing. This method breaks down the complex processing into five clear steps (S1-S5), allowing operators to follow the steps precisely, reducing the risk of misoperation and shortening the training cycle. By adjusting the displacement of the sliding end flange fixing device 3 and the height of the steel pipe support height adjustment device 4, it can quickly adapt to steel pipe frames of different lengths and diameters, achieving "one machine for multiple uses." The flange pre-positioning in S1 and the sliding end preparation in S2 can be performed simultaneously, saving overall processing time. The pre-displacement design of the sliding end flange fixing device 3 in S2 provides sufficient space for steel pipe installation, avoiding the risk of collision. The steel pipe height adjustment in S3 and the sliding end tight-fitting adjustment in S4 can be quickly connected, avoiding process waiting. In step S1, the flange positioning device 7 utilizes a "cross-shaped" baseline, center line, and cross scale 8 to achieve millimeter-level radial and axial positioning of the steel pipe flange 13, ensuring the docking accuracy between the steel pipe flange 13 and the steel pipe body 12. The electromagnet 6's adsorption and fixing function eliminates the slight displacement of the steel pipe flange 13 before welding, avoiding eccentricity caused by vibration. In step S3, the jack 10 adjusts the height of the steel pipe body 12, and combined with a laser alignment instrument (optional), dynamically aligns the center line of the steel pipe body 12 with the center lines of the two steel pipe flanges 13. In step S4, the tight-fitting adjustment of the sliding end flange fixing device 3 further eliminates assembly gaps, ensuring that the coaxiality of the frame meets the standard after welding. The locking function of the sliding end clamping device 5 in step S4 can correct docking deviations caused by bending of the steel pipe body 12 or processing errors of the steel pipe flange 13 in real time. The jacks 10 of the steel pipe support height adjustment device 4 support stepless height adjustment, which can compensate for the deflection of the steel pipe body 12 caused by its own weight or uneven ground, ensuring that the welding surface is level. The close-fitting design (S3, S4) eliminates assembly gaps and reduces the risk of welding defects such as porosity and incomplete fusion. The system layout allows operators to weld the steel pipe flanges 13 simultaneously from both sides, balancing welding stress and further reducing the risk of frame twisting. This method of use solves the pain points of low precision, poor efficiency, and large deformation in traditional steel pipe frame processing through closed-loop control of "precise positioning - dynamic adjustment - rigid fixing - symmetrical welding", providing an efficient, reliable, and flexible solution for industrialized construction.

[0049] In summary, this invention solves the problem of concentric assembly of steel pipe frame components, enabling smooth connections between steel components and in multiple directions on the installation site. Simultaneously, it achieves efficient, standardized, and factory-processed steel pipe components, with most components being standard parts. This addresses the challenges of diverse steel pipe frame structures and the inability to use universally due to the unique nature of each frame type on construction sites. This invention is simple in structure, easy to operate, economical, reusable, and has ideal versatility, making it suitable for widespread adoption.

[0050] It should be understood that although this specification describes one embodiment, it does not mean that the embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in this embodiment can also be appropriately arranged and combined to form other embodiments that can be understood by those skilled in the art.
