Description

[Technical Field]

[0001] The present invention relates to a groove preparation operation support system and a groove preparation method. [Background technology]

[0002] Various plants require a large number of pipes, and when joining these pipes by girth welding, proper groove preparation is required to ensure that the dimensions of the groove shape fall within the tolerances in order to ensure welding quality. Centering work to align the axis of the pipe with the axis of the groove preparation machine is important, and this is disclosed, for example, in Patent Document 1.

[0003] The groove preparation machine described in Patent Document 1 fixes the pipe using a centering bed with a V-shaped groove to perform horizontal centering based on the outer diameter of the pipe. Furthermore, centering in the vertical direction is performed using a spacer based on the outer diameter of the pipe. This allows for uniform groove preparation based on the outer diameter of the pipe. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2002-79402 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the technology of Patent Document 1, which performs centering by grasping the outside of the pipe to ensure proper groove processing, does not take into account cases where the pipe cannot be grasped from the outside or where it is necessary to set the groove processing machine axis at an arbitrary angle relative to the pipe axis.

[0006] An object of the present invention is to provide a groove processing operation support system and a groove processing method that can easily adjust the misalignment between the axis of a workpiece to be processed and the axis of a groove processing machine and ensure centering. [Means for solving the problem]

[0007] The groove preparation work support system of the present invention is a groove preparation work support system equipped with a groove preparation machine that prepares grooves on members to be subjected to circumferential welding groove preparation, and is characterized in that it comprises a first axial measurement device that detects axial data of the groove preparation machine, a second axial measurement device that detects axial data of the circular member, an axial data processing unit that calculates axis deviation from data obtained by the first axial measurement device and the second axial measurement device, and a display device that displays the axis deviation from information on the axis deviation from the axial data processing unit.

[0008] Alternatively, the groove preparation method of the present invention is a groove preparation method using a groove preparation machine that prepares grooves on members to be subjected to circumferential welding groove preparation, and includes a first step of detecting axial data of the groove preparation machine, a second step of detecting axial data of the circular member, a third step of calculating an axial center deviation from the data obtained in the first step and the second step, and a fourth step of displaying the axial center deviation from the information on the axial center deviation. [Effects of the Invention]

[0009] According to the present invention, it is possible to provide a groove processing operation support system and a groove processing method that can easily adjust the misalignment between the axis of the workpiece to be processed and the axis of the groove processing machine, thereby ensuring centering.

[0011] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that the present disclosure is not limited to these embodiments, and when there are multiple embodiments, the present disclosure also includes configurations that combine the embodiments. Furthermore, the components in the embodiments include those that can be easily imagined by a person skilled in the art, those that are substantially the same, and those that are within the so-called equivalent range. [Example]

[0012] In the first embodiment, the target workpiece to be processed is described as a pipe 1. However, the present invention is also applicable to groove processing of columnar members, cylindrical members, and the like as the member to which circumferential welding groove processing is applied.

[0013] 1 shows the configuration of a pipe groove preparation operation support system according to this embodiment. The system includes a first axial direction measuring device 3a, a second axial direction measuring device 3b, an axial direction data processing unit 4, and a display device 5.

[0014] The first axial direction measuring device 3a is attached in a circular shape around the groove processing machine 2. The second axial direction measuring device 3b is attached in a circular shape around the pipe 1, which is the workpiece to be processed. The first axial direction measuring device 3a of the groove processing machine 2 measures the axial direction of the groove processing machine 2, and the axial direction data is transmitted to the axial direction data processing unit 4. The second axial direction measuring device 3b of the pipe 1 measures the axial direction of the pipe 1, and the axial direction data is transmitted to the axial direction data processing unit 4.

[0015] The axial data processing unit 4 performs digitization and imaging processing on the axial data of the piping 1 and the groove preparing machine 2. For example, the digitization involves calculating the deviation angle between the groove preparing machine axis Xa and the piping axis Xb. This information is sent to the display device 5. In addition to displaying the layout of the piping 1 and the groove preparing machine 2, the display device 5 visually displays the groove preparing machine axis Xa and the piping axis Xb, which are the axes in the axial directions of the piping 1 and the groove preparing machine 2. It also numerically displays the deviation angle between the groove preparing machine axis Xa and the piping axis Xb.

[0016] In this way, the data can be displayed visually and numerically on the display device (display). The axis alignment can be adjusted while viewing the groove cutting machine axis Xa and the pipe axis Xb displayed on the display device 5. Furthermore, fine adjustments can be made while viewing the numerical value of the misalignment angle between the groove cutting machine axis Xa and the pipe axis Xb. Conventionally, adjusting the groove cutting of pipes with misaligned axes required skilled experience, but in recent years the number of skilled technicians has been decreasing, making it difficult to handle the aforementioned pipe groove cutting in the future. However, this embodiment makes it possible for workers to easily and appropriately align the axes of the groove cutting machine regardless of experience.

[0017] The display device 5 can be a display such as a PC or tablet. This display can be used as augmented reality goggles, and the misalignment of the piping 1 and the groove preparation machine 2 can be superimposed on an actual image of the piping 1 and the groove preparation machine 2 and displayed on the augmented reality goggles, making it easier for the worker to perform centering adjustment work. In addition, the misalignment can be grasped visually and numerically. By adjusting the installation of the groove preparation machine based on this, groove preparation can be performed at any angle.

[0018] Next, the centering adjustment will be specifically described with reference to Figures 2 and 3. Figure 2 is an explanatory diagram for explaining the shaft adjustment operation according to this embodiment, and Figure 3 is an explanatory diagram for explaining the state after the shaft adjustment operation according to this embodiment.

[0019] In this embodiment, a pipe 1 is used as a component to be welded with a circumferential groove. The procedure includes a first step of detecting axial data from the groove preparation machine, a second step of detecting axial data of the component, a third step of calculating the misalignment of the axis from the data obtained in the first and second steps, and a fourth step of displaying the misalignment of the axis from the misalignment information. This makes it easy to check the misalignment of the axis, facilitating the work of adjusting the axis.

[0020] In the fourth step, misalignment information of the pipe 1 and the groove processing machine is superimposed on the actual image of the components, the pipe 1 and the groove processing machine, and displayed on the augmented reality goggles. As a result, the misalignment of the axis can be easily confirmed on the image on the goggles, making it easier to perform the axis alignment work. In the fourth step, angle information of the misalignment of the pipe 1 and the groove processing machine is displayed. As a result, the misalignment of the axis can be easily confirmed as an angle value on the goggles, making it easier to perform the axis alignment work.

[0021] As shown in Fig. 2, a second axial direction measuring device 3b that measures the axial direction of the pipe 1 is attached in a circular shape to the pipe 1. A first axial direction measuring device 3a that measures the axial direction of the groove preparing machine 2 is attached in a circular shape to the groove preparing machine 2. In the figure, the groove preparing machine axis Xa is tilted at an angle A degrees with respect to the pipe axis Xb.

[0022] As described above, the display device 5 displays the pipe axis Xb and the groove machine axis Xa of the pipe 1 and the groove machine 2 superimposed on the actual image of the pipe 1 and the groove machine 2, allowing the misalignment state to be visually confirmed. The misalignment angle A can also be displayed numerically. While viewing this displayed image, the groove machine 2 is fixed to the pipe 1 so that the cutting edge 6 can rotate. Regarding this fixation, the misalignment can be adjusted while viewing the misalignment state image and the numerical value of the misalignment angle A, and the position can be adjusted as shown in FIG. 3.

[0023] 3, the pipe axis Xb and the groove machine axis Xa are aligned, and the cutting edge 6 rotates about the groove machine axis Xa, so that the corner of the pipe 1 can be machined. Depending on the work situation, there may be cases where the pipe axis Xb and the groove machine axis Xa are not aligned, and the groove machine 2 is fixed to the pipe 1 at a predetermined angle, and the adjustment mechanism of this embodiment can also be applied in such cases.

[0024] Here, there are two conventional methods for fixing the groove preparation machine 2 to the pipe 1. One is a method of fixing the pipe 1 from the outside using a jig. In addition, components such as seats and lugs may be attached to the outside of the pipe 1, and when such components are present near the pipe cross section where groove preparation is to be performed, or when performing groove preparation for an elbow or tee, a groove preparation machine that grips the pipe from the outside may not be usable. In such cases, as another method, an internal groove preparation machine that grips the pipe 1 from the inside is used. In this embodiment, both external and internal gripping of the pipe 1 is applicable.

[0025] Furthermore, due to construction tolerances during pipe installation, the axes of the connected pipes may be misaligned in the final spool. In such cases, it is necessary to adjust the groove surface to be appropriately shifted by a specified angle from the plane perpendicular to the pipe axis. Normally, as shown in Figure 3, the pipe axis Xb and the groove preparation machine axis Xa are aligned, but this embodiment can also be applied when adjusting to shift by the specified angle described above.

[0026] As described above, in order to solve the above problems, the groove preparation support system disclosed herein attaches an attachment measuring device that detects the axial direction to both the pipe to be prepared and the groove preparation machine, and calculates the misalignment of their axes. The axes of the pipe and the groove preparation machine, as well as the amount of misalignment between their axes, are then displayed on a display and presented to the worker. This allows the worker to visually and numerically grasp the axes of the pipe and the groove preparation machine, and adjust the misalignment as desired. Regardless of experience, the groove preparation worker can correct the misalignment between the pipe axis and the groove preparation machine axis and perform reliable centering.
