Description

Technical Field

[0001] This invention relates to the field of detection technology, and in particular to a tooling and method for placing central feature points on a mobile device. Background Technology

[0002] During the installation and construction of industrial equipment, according to the equipment's process and installation requirements, it is necessary to use professional testing instruments to locate the center point (line) of the production line unit, the center point (line) of the equipment, the horizontal plane of the ground, and the elevation benchmark. The center point (line) and the elevation benchmark are then placed in fixed positions on site where testing can be carried out, to facilitate equipment installation and adjustment until the equipment installation is completed.

[0003] With the increasing precision requirements of industrial equipment installation, traditional methods such as plumb lines and gauge wires are no longer sufficient. Currently, most industrial equipment installations utilize high-precision optical inspection instruments such as laser trackers and total stations to detect center points (lines) and elevation benchmarks on-site. However, when using optical inspection instruments in conjunction with equipment installation, it is necessary to collect reference feature surfaces and feature points representing the unit's center point (line), equipment center point (line), the horizontal plane, and elevation benchmarks at different installation stages to complete digital modeling or equipment centering. Then, feature points representing other actual spatial positions of the equipment, reflecting its technological and design specifications, are sequentially collected and analyzed to obtain the actual spatial position of the unit and guide equipment installation and adjustments.

[0004] However, during the installation of the generating unit equipment, the original characteristic benchmark detection surfaces of the generating unit center point (line), equipment center point (line), earth level plane and elevation benchmark will be gradually obscured or covered by the installed equipment. As a result, the benchmark characteristic surfaces and characteristic points that characterize the generating unit center point (line), equipment center point (line) and elevation benchmark cannot be continuously and completely preserved throughout the entire equipment installation process. This lack of a fixed and unified detection benchmark brings an unsolvable contradiction to the work of optical detection instruments such as laser trackers and total stations in conjunction with equipment installation. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a mobile equipment installation center feature point placement tool and its usage method. This tool and its usage method can realize the rapid, accurate and continuous positioning of the equipment unit center point (line), equipment center point (line), ground horizontal plane and elevation benchmark point at the equipment installation and construction site, improve the accuracy and efficiency of equipment spatial position installation and inspection, reduce the inspection workload, reduce inspection costs, and avoid quality problems in inspection operations.

[0006] To solve the above-mentioned technical problems, the present invention provides a mobile equipment installation center feature point placement fixture comprising a bracket, a detection platform, a slider, four positioning bolts, and four wheels. The bracket includes a bottom frame, a vertical frame, and a diagonal support frame. The vertical frame is vertically disposed on one side of the bottom frame, and the diagonal support frame is inclinedly disposed on the other side of the bottom frame. The detection platform is disposed at the top of the vertical frame and the diagonal support frame. The top surface of the detection platform has a groove along its length. The slider is located in the groove and slides along the groove. The top surface of the slider has a notch in the center. The bottom frame has screw holes at its four corners. The four positioning bolts are screwed into the screw holes at the four corners of the bottom frame, or the four wheels are screwed into the screw holes at the four corners of the bottom frame via screws on the top surface of the wheel frame. The top corner of the bottom frame has countersunk holes.

[0007] Furthermore, the bottom surface of the slider is provided with a cylinder, which slides within a groove on the top surface of the detection platform, and the diameter and length of the cylinder match the width and depth of the groove.

[0008] Furthermore, the depth, width, and length of the groove on the top surface of the detection platform are 20×20×800mm, respectively.

[0009] Furthermore, the spacing between adjacent countersunk holes at the top corner of the bottom frame is 1000mm.

[0010] A method for using the aforementioned fixture for placing central feature points on mobile equipment includes the following steps:

[0011] Step 1: Determine the approximate location of the production line unit center point or center line, and the equipment center point or center line, based on the required installation center location.

[0012] Step 2: Tighten the four wheels of the placement fixture to the screw holes at the four corners of the bottom frame through the screws on the top surface of the wheel frame. Move the bracket to the equipment installation site through the four wheels, and make the length direction of the slide of the testing platform perpendicular to the center line of the unit or the center line of the equipment.

[0013] Step 3: Use a suspension line or a pull line to move the center position of the bracket to approximately the center point or center line of the production line unit or the equipment, ensuring that the center point or center line of the production line unit or the equipment is within the length range of the slide groove on the top surface of the testing platform.

[0014] Step 4: Remove the wheels from the four corners of the bottom frame, screw the four positioning bolts into the screw holes at the four corners of the bottom frame, and fix the bracket to the ground with the four positioning bolts to ensure that the bracket does not move during the entire equipment installation process;

[0015] Step 5: Use a level to measure the relative elevation of the countersunk holes at the corners of the top surface of the bottom frame. Set the countersunk hole at the intersection of the two lines as the reference point, designated as point O. The countersunk holes at the other ends of the two perpendicular lines are designated as points A and B. The elevation of point O is ±0, the elevation of point A relative to point O is a, and the elevation of point B relative to point O is b. Place the target at points O, A, and B, and use a laser tracker or total station detection system to collect the spatial position of the target into the detection system.

[0016] Step 6: Model within the detection system. Establish a coordinate system S with point O as the origin and points O, A, and B as the plane. In coordinate system S, the coordinates of point O are (0, 0, 0), the length of OA is 1000mm, the length of OB is 1000mm, then the coordinates of point A are (1000, 0, 0), and the coordinates of point B are (0, 1000, 0).

[0017] Step 7: The detection system creates point A1 on the X-axis with coordinates (1000, 0, -a) and point B1 on the Y-axis with coordinates (0, 1000, -b). A coordinate system S1 is created using points O, A1, and B1 as a plane. Within coordinate system S1, the coordinates of point A are (1000, 0, a) and the coordinates of point B are (0, 1000, b). Therefore, the created coordinate system S1 is parallel to the horizontal plane of the earth. Coordinate system S1 is used to determine the equipment tilt during the unit installation process.

[0018] Step 8: Use a laser tracker or total station to collect the center point or center line of the production line unit and the equipment. Place the cursor at the intersection of the center point or center line and the length of the slide groove on the testing platform. Slide the slider along the slide groove to the intersection position and collect the coordinates of the notch on the top surface of the slider. If there is a deviation between the position of the notch on the top surface of the slider and the center point or center line, move the slider slightly along the length of the slide groove until the measuring point of the notch on the top surface of the slider meets the requirements of the center point or center line. Use hot melt adhesive to fix the slider in the slide groove of the testing platform to ensure that the slider will not be displaced during the entire equipment installation process.

[0019] Furthermore, the elevation values ​​of points A and B in coordinate system S1 can be compared with the elevation values ​​of the plant settlement system where the equipment is installed, and retained as the original elevation values. After the equipment installation is completed, the elevation points will be pre-embedded at appropriate locations.

[0020] Because the present invention employs the above-mentioned technical solution for the mobile equipment installation center feature point placement fixture and its usage method, the fixture's support is composed of a bottom frame, a vertical frame, and a diagonal brace frame. A detection platform is located at the top of the support, with a groove on its top surface. A notch is centrally located on the top surface of the slider, which slides along the groove. Screw holes are located at the four corners of the bottom frame, with four positioning bolts or wheels positioned within these holes. Countersunk holes are located at the corners of the bottom frame's top surface. This method first determines the approximate location of the production line unit's center point or centerline, and the equipment's center point or centerline. The support is then moved to the equipment installation site using wheels and positioned at the approximate location of the production line unit's center point or centerline, and the equipment's center point or centerline. The wheels are removed and replaced with positioning bolts to fix the support. A coordinate system parallel to the horizontal plane is created using the countersunk holes at the corners of the bottom frame's top surface to determine the equipment tilt during installation. The feature point placement operation is achieved by measuring the position of the notch on the top surface of the slider to align it with the production line unit's center point or centerline, and the equipment's center point or centerline. This tooling and its usage method improve the accuracy and efficiency of equipment spatial positioning and testing, reduce testing workload, lower testing costs, and avoid potential quality problems in testing operations.

[0028] Implementation, for example Figures 1 to 6As shown, the mobile equipment installation center feature point placement fixture of the present invention includes a bracket 1, a detection platform 2, a slider 3, four positioning bolts 4, and four wheels 5. The bracket 1 includes a bottom frame 11, a vertical frame 12, and a diagonal support frame 13. The vertical frame 12 is vertically disposed on one side of the bottom frame 11, and the diagonal support frame 13 is inclinedly disposed on the other side of the bottom frame 11. The detection platform 2 is disposed at the top of the vertical frame 12 and the diagonal support frame 13. The top surface of the detection platform 2 is provided with a groove 21 along the length direction. The slider 3 is located in the groove 21 and slides along the groove 21. The top surface of the slider 3 is provided with a notch 31 in the center. The bottom frame 11 is provided with screw holes 14 at the four corners. The four positioning bolts 4 are screwed into the screw holes 14 at the four corners of the bottom frame 11, or the four wheels 5 are screwed into the screw holes 14 at the four corners of the bottom frame 11 through the screws 51 on the top surface of the wheel frame. The top corner of the bottom frame 11 is provided with countersunk holes 15.

[0029] Preferably, the bottom surface of the slider 3 is provided with a cylinder 32, which slides within the groove 21 on the top surface of the detection platform 2, and the diameter and length of the cylinder 32 match the width and depth of the groove 21.

[0030] Preferably, the depth, width and length of the groove 21 on the top surface of the detection platform 2 are 20×20×800mm.

[0031] Preferably, the distance between adjacent countersunk holes 15 at the top corner of the bottom frame 11 is 1000mm.

[0032] A method for using the aforementioned fixture for placing central feature points on mobile equipment includes the following steps:

[0033] Step 1: Determine the approximate location of the production line unit center point or center line, and the equipment center point or center line, based on the required installation center location.

[0034] Step 2: Tighten the four wheels of the placement fixture to the screw holes at the four corners of the bottom frame through the screws on the top surface of the wheel frame. Move the bracket to the equipment installation site through the four wheels, and make the length direction of the slide of the testing platform perpendicular to the center line of the unit or the center line of the equipment.

[0035] Step 3: Use a suspension line or a pull line to move the center position of the bracket to approximately the center point or center line of the production line unit or the equipment, ensuring that the center point or center line of the production line unit or the equipment is within the length range of the slide groove on the top surface of the testing platform.

[0036] Step 4: Remove the wheels from the four corners of the bottom frame, screw the four positioning bolts into the screw holes at the four corners of the bottom frame, and fix the bracket to the ground with the four positioning bolts to ensure that the bracket does not move during the entire equipment installation process;

[0037] Step 5: Use a level to measure the relative elevation of the countersunk holes at the corners of the top surface of the bottom frame. Set the countersunk hole at the intersection of the two lines as the reference point, designated as point O. The countersunk holes at the other ends of the two perpendicular lines are designated as points A and B. The elevation of point O is ±0, the elevation of point A relative to point O is a, and the elevation of point B relative to point O is b. Place the target at points O, A, and B, and use a laser tracker or total station detection system to collect the spatial position of the target into the detection system.

[0038] Step 6: Model within the detection system. Establish a coordinate system S with point O as the origin and points O, A, and B as the plane. In coordinate system S, the coordinates of point O are (0, 0, 0), the length of OA is 1000mm, the length of OB is 1000mm, then the coordinates of point A are (1000, 0, 0), and the coordinates of point B are (0, 1000, 0).

[0039] Step 7: The detection system creates point A1 on the X-axis with coordinates (1000, 0, -a) and point B1 on the Y-axis with coordinates (0, 1000, -b). A coordinate system S1 is created using points O, A1, and B1 as a plane. Within coordinate system S1, the coordinates of point A are (1000, 0, a) and the coordinates of point B are (0, 1000, b). Therefore, the created coordinate system S1 is parallel to the horizontal plane of the earth. Coordinate system S1 is used to determine the equipment tilt during the unit installation process.

[0040] Step 8: Use a laser tracker or total station to collect the center point or center line of the production line unit and the equipment. Place the cursor at the intersection of the center point or center line and the length of the slide groove on the testing platform. Slide the slider along the slide groove to the intersection position and collect the coordinates of the notch on the top surface of the slider. If there is a deviation between the position of the notch on the top surface of the slider and the center point or center line, move the slider slightly along the length of the slide groove until the measuring point of the notch on the top surface of the slider meets the requirements of the center point or center line. Use hot melt adhesive to fix the slider in the slide groove of the testing platform to ensure that the slider will not be displaced during the entire equipment installation process.

[0041] Preferably, the elevation values ​​of points A and B in coordinate system S1 can be compared with the elevation values ​​of the settlement system of the plant where the equipment is installed, and the original elevation values ​​can be retained. After the equipment installation is completed, the elevation points can be pre-embedded at appropriate locations.

[0042] During the temporary creation of production line unit center points (lines) and equipment center points (lines) at the equipment installation and construction site, due to the needs of engineering installation, the center of the unit or equipment usually appears in the form of a center line. Therefore, the placement tooling is usually used in pairs, set on both sides of the unit or equipment, such as the inlet and outlet, the operation side and the drive side.

[0043] After the placement fixtures on both sides of the unit or equipment are adjusted and fixed to both sides of the installation, the line connecting the top recesses of the sliders on the testing platform of a set of placement fixtures is the center line of the unit or equipment. Using the countersunk holes at the corners of the top surface of the bottom frame of the placement fixtures on both sides of the unit or equipment, a geodetic level system for assessing the tilt of the equipment installation can be created within the optical inspection system. This system can also be used to reserve elevation benchmarks on-site, ensuring that the center point (line) of the production line unit, the center point (line) of the equipment, the geodetic level, and the elevation points can be easily obtained and maintained until the overall installation is completed.

[0044] This laying-out tooling and its usage method overcome the shortcomings of traditional methods for creating geodetic datum surfaces. Users can create spatial geodetic datum surfaces with high horizontal accuracy and a wide range in any environment, improving the accuracy and efficiency of equipment spatial position detection, reducing the workload of detection, lowering detection costs, and avoiding potential quality problems in detection operations. By applying precision optical instruments in conjunction with the use of this laying-out tooling, it is possible to quickly, accurately, and continuously locate the unit center point (line), equipment center point (line), geodetic horizontal plane, and elevation points at the equipment installation and construction site. This overcomes the shortcomings of traditional equipment installation methods, which make it difficult to accurately lay out and retain center lines and elevations on-site for extended periods.
