Description

Technical Field

[0001] This utility model relates to the field of pipe assembly welding technology, specifically to a novel prefabricated large-diameter pipe assembly welding auxiliary device. Background Technology

[0002] Based on practical engineering experience and research on welding auxiliary devices for conventional large-diameter pipeline assemblies, it has been found that conventional auxiliary devices have low versatility, low reuse rate, and are not conducive to storage and transportation. During project turnover, conventional auxiliary devices often require reprocessing and modification due to the limitations of their design structure, resulting in a significant waste of labor and material resources. Utility Model Content

[0003] To address the aforementioned problems, this utility model discloses a novel prefabricated large-diameter pipe assembly welding auxiliary device. Introducing a modular design concept, it upgrades and transforms traditional large-diameter pipe assembly welding auxiliary devices. Through ingenious design, the new auxiliary device can be adjusted within a certain range of adaptable pipe diameters, greatly improving its versatility and utilization rate, indirectly reducing labor and material costs. Based on its modular design, the device can be transported through reasonable disassembly, reducing transportation space, lowering transportation costs, and minimizing potential damage during transport. Furthermore, its modular design allows for rapid replacement or fabrication of new modules when a single module is damaged, resulting in lower maintenance costs and further cost reduction and efficiency improvement during construction.

[0004] The specific plan is as follows: A novel prefabricated large-diameter pipe assembly welding auxiliary device includes a frame base steel, vertical support steel, diagonal bracing steel, and casters. The frame base steel is I-shaped and consists of a transversely arranged middle steel and two longitudinally arranged edge steels on both sides. The vertical support steels are symmetrically arranged on the frame base steel and can move laterally along it. Diagonal bracing steels are connected to the sides of both vertical support steels, and casters are installed at the upper ends.

[0005] Furthermore, the edge steel is bolted to the middle steel by a connecting plate welded to the middle, and the connecting plate has an opening (M16).

[0006] Furthermore, the upper flanges of the edge steel and the middle steel are equidistantly perforated with holes (M16) in the transverse direction to connect with the reinforcing plate at the bottom of the vertical support steel. This allows the vertical support steel to be connected and fixed with bolts at any four adjacent bolt hole positions, thereby achieving variable spacing adjustment and adapting to pipes with a wider range of diameters.

[0007] Furthermore, the upper and lower flanges of the vertical support steel have symmetrical bolt holes for connection with the diagonal bracing steel, thus strengthening the entire device. The vertical support steel, the intermediate steel, and the diagonal bracing are cleverly integrated through design, ensuring that when any four adjacent bolt holes on the vertical support steel are connected to the intermediate steel, the diagonal bracing always has a corresponding bolt hole on the intermediate steel, thereby guaranteeing the stable and safe use of the entire device. A caster wheel is installed at the upper end via a caster wheel connecting plate.

[0008] The beneficial effects of this utility model are as follows: By incorporating a modular design concept, this new auxiliary device can adjust its spacing within a certain range to accommodate pipes of a wider range of diameters, giving it extremely high versatility and flexibility. Compared to conventional devices, this new auxiliary device effectively improves resource utilization and efficiency, providing a reliable auxiliary device design solution for the assembly welding of large-diameter pipes.

[0018] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0019] like Figure 1-4 As shown, this utility model provides a novel prefabricated large-diameter pipe assembly welding auxiliary device, including a frame base steel 1, vertical support steel 2, diagonal bracing steel 3, and casters 4; the frame base steel 1 is I-shaped, consisting of a longitudinally arranged middle steel 11 and two longitudinally arranged edge steels 12 on both sides; the vertical support steels are symmetrically arranged on the frame base steel and can move laterally along it; diagonal bracing steels are connected to the sides of the two vertical support steels, and casters are installed at the upper ends.

[0020] In this embodiment, the edge steel is bolted to the middle steel by a connecting plate 5 welded to the middle, and the connecting plate 5 has an opening (M16).

[0021] In this embodiment, the upper flanges of the edge steel and the middle steel are equidistantly perforated with holes (M16) in the transverse direction to connect with the reinforcing plate 6 at the bottom of the vertical support steel. This allows the vertical support steel to be connected and fixed with bolts at any four adjacent bolt hole positions, thereby achieving variable spacing adjustment and adapting to pipes with a wider range of diameters.

[0022] In this embodiment, the upper and lower flange plates of the vertical support steel have symmetrical bolt holes for connection with the diagonal bracing steel to strengthen the entire device. The vertical support steel, the intermediate steel, and the diagonal bracing are cleverly integrated through design, so that when any four adjacent bolt holes on the vertical support steel and the intermediate steel are connected, the diagonal bracing can always have a corresponding bolt hole on the intermediate steel for connection, thereby ensuring the stable and safe use of the entire device. A caster wheel 4 is installed at the upper end through a caster wheel connecting plate 7.

[0023] The principle of use of this application is as follows: 1. Device spacing adjustment Before using this device, the spacing of the auxiliary supports must first be adjusted according to the pipe diameter to be adapted. This spacing adjustment mainly relies on the bolt holes that are evenly spaced on the edge and middle steel sections. Figure 5 As shown.

[0024] Using equally spaced adjusting bolt holes, the vertical support steel sections can be fixed on any four adjacent holes, thereby adjusting the center distance between two vertical support steel sections. Furthermore, as the position of the vertical support steel sections changes, the corresponding diagonal bracing steel sections can be adjusted accordingly, ensuring the safety and stability of the entire structure. According to the design, the minimum center distance of this device is such that the movable vertical support steel sections are installed on the four innermost adjacent bolt holes, while the diagonal bracing is placed on the outer side for fixation. Figure 6 As shown.

[0025] The maximum center-to-center spacing is such that movable vertical support steel is installed on the four outermost adjacent bolt holes, while diagonal braces are placed on the inner side for fixation. Figure 7 As shown.

[0026] In addition to the minimum and maximum spacing, the spacing can be adjusted multiple times between the minimum and maximum spacing according to actual usage requirements. Furthermore, depending on the actual site conditions, additional bolt holes can be added to accommodate pipes with smaller diameters, or the length of the intermediate steel section can be extended to accommodate pipes with larger diameters.

[0027] 2. Level before use Leveling of this device primarily utilizes wedge shims. After adjusting the spacing and determining the installation position, the device is placed with a uniform orientation, and the auxiliary supports used in conjunction should be ensured to be on the same horizontal line. Leveling is mainly performed using a spirit level, and the leveled auxiliary supports greatly facilitate high-quality pipe assembly.

[0028] 3. High-strength casters are used. The high-strength casters play a crucial role in this device. During the pipe assembly and welding process, the pipes can be easily rotated, greatly facilitating the assembly and welding process. Secondly, the casters' flexibility allows them to adjust their deflection angle according to the direction of force during the lifting process after pipe welding, effectively reducing the shear stress on the casters during pipe lifting.

[0029] 4. Multiple devices can be used in combination. This device requires the use of other devices in practical applications, such as... Figure 8 As shown.

[0030] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
