Technical Field

[0001] This invention relates to the field of steel structure node processing technology, and in particular to an auxiliary construction tooling for steel structure nodes. Background Technology

[0002] With the rapidly increasing demand for offshore oil platforms, in order to meet the requirements of project construction schedule and construction quality, some convenient auxiliary processing methods are proposed to improve processing quality and efficiency. For the construction of jacket structures, the most time-consuming and labor-intensive work is the processing of the nodes.

[0003] Currently, the fabrication of jacket framework nodes is mainly carried out by welding each component after positioning it. Among these steps, component positioning is a particularly tedious and difficult task. During fabrication, the overall structure requires multiple positioning adjustments and welding operations at varying angles. This can negatively impact the manufacturing efficiency and accuracy of jacket framework node fabrication. Summary of the Invention

[0008] A support rod conveying table is provided on one side of the welding area. The support rod conveying table is equipped with several positioners. The position and angle of the positioners are adjustable. Each positioner has several support rod conveying rollers and support rod rotating rollers that are spaced apart on both sides along its length and width directions.

[0009] A facade fixing device is provided above the welding area and is used to fix the welded support rods.

[0012] Preferably, the main chord conveying roller or the main chord rotating roller can be vertically mounted on the main chord conveying platform.

[0013] Preferably, the support rod conveying roller is inclined toward the middle of the positioner in the width direction.

[0014] Preferably, the support rod conveying roller or the support rod rotating roller can be vertically mounted on the positioner.

[0015] Preferably, the support rod conveyor has three of the aforementioned positioners.

[0016] Preferably, the support rod conveying platform has adjustment seats disposed opposite to each positioner on both sides, and each adjustment seat is equipped with an adjustment bolt that abuts against the positioner.

[0017] Preferably, the locator also has a limiting plate arranged along its length.

[0018] Preferably, the facade fixing device includes two V-shaped clips arranged opposite each other. The V-shaped clips are hinged at the end away from the welding area. Each V-shaped clip is also provided with a pulley and a sliding cable wrapped around the pulley on one side. One end of the sliding cable is connected to the V-shaped clip.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] (2) The positioner of the present invention has automatic transmission and adjustment functions, and can accurately position the position of the rod and the angle of the weld.

[0022] (3) The positioner of the present invention can adjust the position relationship according to the required angle, and simultaneously position the relative relationship between all support rods and the main chord rod, thereby reducing the cumulative error caused by the separate positioning of multiple support rods;

[0042] Currently, the fabrication of jacket structure nodes mainly involves welding each component after positioning it. However, component positioning is a complex and difficult task.

This negatively impacts the manufacturing efficiency and accuracy of jacket structure node fabrication. Therefore, this invention provides an auxiliary construction fixture for steel structure nodes, which can significantly improve the manufacturing efficiency and accuracy of jacket structure node fabrication.

[0043] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the invention and to fully convey the scope of the invention to those skilled in the art.

[0044] Example 1

[0045] like Figures 1-4 As shown, this embodiment of the invention provides an auxiliary construction tooling for steel structure nodes, including:

[0046] The main chord conveyor 1 has several main chord conveyor rollers 11 spaced apart on both sides along its length direction. The middle part of the main chord conveyor 1 is a welding area 12. The welding area 12 has several main chord rotating rollers 13 spaced apart on both sides along the width direction of the main chord conveyor 1.

[0047] Support rod conveying table 2 is set on one side of welding area 12. Support rod conveying table 2 has several positioners 21. The position and angle of the positioners 21 can be adjusted. Each positioner 21 has several support rod conveying rollers 22 and support rod rotating rollers 23 that are spaced apart on both sides along its length and width directions.

[0048] Facade fixing device 3 is located above welding area 12 and is used to fix the welded support rods.

[0049] The steel structure node auxiliary construction tooling provided in this embodiment of the invention can be widely used in the field of marine engineering technology, as well as in other fields involving steel structure nodes. It integrates functions such as rod transmission, positioning, adjustment, fixing and welding, and can greatly improve the manufacturing efficiency and processing accuracy of jacket nodes.

[0050] Furthermore, the main chord conveyor roller 11 is inclined toward the middle of the main chord conveyor table 1 in the width direction.

[0051] In this embodiment, the main chord conveying roller 11 is inclined toward the middle of the width direction of the main chord conveying platform 1. When the main chord is placed on the main chord conveying roller 11 on both sides of the main chord conveying platform 1, the position of the main chord can be directly determined. This can effectively reduce the amount of adjustment work in the processing of steel structure nodes, thereby further improving the work efficiency of this embodiment.

[0052] Preferably, the tilt angle of the main chord transmission roller 11 is 45°.

[0053] Of course, the tilt angle of the main chord transmission roller 11 of the present invention is not limited to 45°. In other embodiments of the present invention, the tilt angle of the main chord transmission roller 11 can be set to other angles according to actual needs. For example, in some specific embodiments, the tilt angle of the main chord transmission roller 11 can also be 15°, 30°, 60° or 75°, etc.

[0054] Furthermore, the main chord conveying roller 11 or the main chord rotating roller 13 can be raised and lowered on the main chord conveying table 1.

[0055] In this embodiment, the main chord conveying roller 11 or the main chord rotating roller 13 can be raised and lowered on the main chord conveying platform 1. When the main chord needs to be rotated, the main chord conveying roller 11 can be lowered or the main chord rotating roller 13 can be raised to avoid friction between the main chord and the main chord conveying roller 11 during rotation. This can reduce the resistance encountered by the main chord during rotation and prevent the main chord from wearing due to friction with the main chord conveying roller 11.

[0056] Specifically, in this embodiment, the main chord rotation roller 13 can be raised and lowered on the main chord conveyor table 1. In the default state, it is 0.5cm to 1cm lower than the elevation of the main chord conveyor roller 11. When it is necessary to rotate the main chord, it can be raised to a position 0.5cm to 1cm higher than the elevation of the main chord conveyor roller 11.

[0057] Furthermore, the support rod transmission roller 22 is inclined toward the center of the positioner 21 in the width direction.

[0058] In this embodiment, by tilting the support rod conveying roller 22 toward the center of the locator 21 in the width direction, the position of the support rod can be directly determined when the support rod is placed on the support rod conveying roller 22 on both sides of the locator 21. This can effectively reduce the amount of adjustment work during the processing of steel structure nodes, thereby further improving the work efficiency of this embodiment.

[0059] Preferably, the tilt angle of the support rod transmission roller 22 is 45°.

[0060] Of course, the tilt angle of the support rod conveying roller 22 of the present invention is not limited to 45°. In other embodiments of the present invention, the tilt angle of the support rod conveying roller 22 can be set to other angles according to actual needs. For example, in some specific embodiments, the tilt angle of the support rod conveying roller 22 can also be 15°, 30°, 60° or 75°, etc.

[0061] Furthermore, the support rod transmission roller 22 or the support rod rotation roller 23 can be raised and lowered on the positioner 21.

[0062] In this embodiment, the support rod transmission roller 22 or the support rod rotation roller 23 can be raised and lowered on the positioner 21. When the support rod needs to be rotated, the support rod transmission roller 22 can be lowered or the support rod rotation roller 23 can be raised to avoid friction between the support rod and the support rod transmission roller 22 during rotation. This can reduce the resistance encountered by the support rod during rotation and prevent the support rod from wearing due to friction with the support rod transmission roller 22.

[0063] Specifically, in this embodiment, the support rod rotating roller 23 can be raised and lowered on the positioner 21. In the default state, it is 0.5cm to 1cm lower than the elevation of the support rod transmission roller 22. When the support rod needs to be rotated, it can be raised to a position 0.5cm to 1cm higher than the elevation of the support rod transmission roller 22.

[0064] Furthermore, the support rod conveyor 2 has three positioners 21.

[0065] like Figure 5 As shown, based on the arrangement of the support rods and the characteristics of the structural type, the structural nodes of the jacket structure can be categorized into three types: T-type, Y-type, and K-type. This embodiment, by setting three positioners 21 on the support rod conveying platform 2, enables it to simultaneously meet the processing requirements of multiple types of steel structural nodes, such as T-type, Y-type, and K-type. Each processing operation only requires selecting the appropriate positioner 21 based on the type of steel structural node being processed.

[0066] It is understood that the number of positioners 21 on the support rod conveyor 2 of the present invention is not limited to three. In some other embodiments, the number can be increased or decreased according to actual needs.

[0067] Furthermore, the support rod conveying platform 2 has adjusting seats 24 disposed on both sides of each positioner 21, and each adjusting seat 24 is equipped with adjusting bolts 25 that abut against the positioner 21. In this embodiment, the horizontal position and placement angle of the positioner 21 can be adjusted within a certain range by adjusting the length of the adjusting bolts 25 on both sides of the positioner 21 to meet different positioning requirements of the support rod.

[0068] For the processing of multiple identical nodes, only the locator 21 needs to be initially adjusted once to accurately position each support rod, and it can be reused. For the processing of the next node component, there is no need to adjust the locator 21 again. This can reduce the amount of repetitive work in the processing of steel structure nodes, thereby greatly improving processing efficiency.

[0069] Preferably, the locator 21 also has a limiting plate 26 disposed along its length.

[0070] In this embodiment, by setting a limiting plate 26 on the positioner 21, when it is necessary to adjust the weld cut angle of the support rod, a positioning part can be set on the support rod according to the position of the weld cut. When rotating the support rod, the positioning part on it is rotated to abut against the limiting plate 26, so that the support rod can be rotated to the required position so that the support rod can be accurately connected with the main chord.

[0071] Furthermore, the facade fixing device 3 includes two opposing V-shaped clamps 31. The V-shaped clamps 31 are hinged at the end away from the welding area 12. Each V-shaped clamp 31 is also provided with a pulley 32 and a sliding cable 33 wound around the pulley 32 on one side. One end of the sliding cable 33 is connected to the V-shaped clamp 31 and is used to raise or lower the V-shaped clamp 31. In this embodiment, when it is necessary to fix the members of the welded support rod, after rotating the main chord until the support rod on it is at a vertical 90°, the V-shaped clamp 31 is lowered into place by the sliding cable 33. After the V-shaped clamp 31 is lowered into place, it will hold the inclined support rod on the main chord, thereby fixing the members of the welded support rod.

[0072] Understandably, for nodes without diagonal supports, such as T-shaped nodes, temporary diagonal braces can be added to the main chord during fabrication to allow the facade fixing device 3 to secure the members during processing. These temporary diagonal braces are then removed after the node fabrication is complete.

[0073] In this embodiment, when processing steel structure nodes, after the support rod and main chord are accurately aligned, the upper part of the weld seam can be welded or pre-welded to a certain strength. Then, the main chord is rotated using the rotating roller 13 until the support rod is at a vertical 90° angle. Subsequently, the fixing clamp is rotated to fix the support rod, facilitating simultaneous welding by multiple people and avoiding unfavorable welding conditions such as overhead welding. Simultaneously, while welding the vertical support rod, another support rod can be positioned and pre-welded horizontally. After the vertical support rod is welded, the main chord is rotated until the newly added support rod is at a vertical 90° angle to complete the welding of the new support rod.

[0074] Example 2

[0075] like Figures 6-11 As shown, this embodiment of the invention uses a K-type node as an example to illustrate the usage method of the auxiliary construction tooling for steel structure nodes provided in Embodiment 1, as detailed below:

[0076] (1) As Figure 6 As shown, the main chord is placed at the front end of the main chord conveyor 1 and conveyed to the welding area 12 in the middle of the main chord conveyor 1 via the main chord conveyor roller 11;

[0077] (2) Based on the connection position and angle between the support rod and the main chord, adjust the positioner 21 to the corresponding position and angle by adjusting the bolt length on both sides of the positioner 21;

[0078] (3) Figure 7 As shown, each support rod is placed on the corresponding positioner 21 and conveyed to the appropriate position by the support rod conveying roller 22;

[0079] (4) The support rod is rotated circumferentially by the support rod rotating roller 23 until the positioning part on it abuts against the limiting rail, so as to determine the angle of the weld section of the support rod and ensure that the support rod and the main chord are accurately connected.

[0080] (5) After the angle of the weld seam of the support rod is adjusted, the support rod is moved to the position of the main chord rod by the support rod transmission roller 22.

[0081] (6) After the support rod is positioned, perform preliminary welding on the support rod until the weld has enough to support the weight of the support rod.

[0082] (7) Figure 8 As shown, the main chord is rotated by the main chord rotating roller 13 until the support is at a vertical 90° angle, and then fixed by the facade fixing device 3;

[0083] (8) Figure 9 As shown, the welding of the support rod is completed by automated welding or by multiple people welding at the same time. At the same time, steps (3) to (6) can be repeated to complete the positioning and preliminary welding of another support rod in the horizontal direction.

[0084] (9) such as Figure 10 As shown, the main chord is rotated by the main chord rotating roller 13 to complete the welding of the new support rod;

[0085] (10) such as Figure 11 As shown, after welding of all the support rods on the main chord is completed, the finished parts are transported to the end of the main chord conveyor table 1 by the main chord conveyor roller 11, and then lifted to the designated site by the crane.

[0086] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
