Description

Technical Field

[0001] This application belongs to the field of linear measurement technology, specifically relating to a segmented measurement method. Background Technology

[0002] In industries such as linear measurement, bridges, building steel structures, and energy and chemical engineering, large templates are required to locate the structure or inspect the linear dimensions during the manufacturing and inspection of product segments and structural shells to ensure the correctness of structural assembly.

[0003] Currently, large segments are primarily manufactured using jigs, whose rigidity is used to control the segment's dimensional profile. During the welding process, significant internal stress is generated in the segments. After the segments are removed from the jig, the stress is released, causing substantial changes in the segment's dimensional profile, exceeding the required tolerances. Therefore, it is essential to measure and control the segment's dimensional profile to meet the needs of subsequent segment joining and allowance pre-trimming.

[0004] In existing technologies, measuring rulers are generally used to measure the key dimensions of the segmented parts. However, the accuracy of the measured linear dimensions is low and cannot meet the needs of subsequent segment connection and allowance pre-adjustment. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a segmented measurement method, which aims to at least partially solve the technical problem that the accuracy of the measured linear dimensions obtained by using a ruler to measure the local key main dimensions of segments is low, and cannot meet the needs of subsequent segmented docking and allowance pre-adjustment.

[0006] The technical solution of this invention is as follows: A segmented measuring fixture, characterized in that it comprises: a traveling component; two height adjustment components respectively disposed at both ends of the traveling component; a clamping component disposed on the traveling component; at least two locking components disposed on the clamping component; a standard component disposed on the traveling component and within the clamping and locking components, wherein the standard component has a first notch with a circular arc cross-section; wherein, the side of the standard component has a first marking line located on the horizontal plane and along the radial direction of the first notch, and the side of the standard component has a plurality of second marking lines spaced at equal angles.

[0007] In some embodiments, the walking component includes: a support frame for supporting the clamping assembly and the standard component; and two walking wheel assemblies, respectively disposed at both ends of the support frame.

[0008] In some embodiments, the height adjustment assembly includes at least two height adjustment members arranged side-by-side at intervals at the ends of the walking member.

[0009] In some embodiments, the clamping assembly includes two clamping members disposed side-by-side at a distance on the traveling member, and the standard member disposed between the two clamping members.

[0010] In some embodiments, the locking assembly includes two locking members disposed on the two clamping members, and the standard member disposed between the two locking members.

[0011] In some implementations, the segmented measuring fixture further includes an operating platform with a second notch, and the traveling component is located within the second notch.

[0012] In some implementations, the operating platform has a clearance groove, and the standard part is partially embedded in the clearance groove.

[0013] Based on the same inventive concept, the present invention also provides a segmented measurement method. Based on the segmented measurement fixture, each end of the segment has two ports. Along the radial direction of the segment, the segment has a first line. The line connecting the two ports at one end of the segment overlaps with the first line. Along the radial direction of a first notch, the first notch has a second line, which is located on a vertical plane. The segmented measurement method includes: adjusting the segment so that both ends of the segment are on the same horizontal plane; adjusting the segment so that the line connecting the two ports at one end of the segment is located on the vertical plane; a traveling component reaching the measurement position; adjusting the position of a standard component within a clamping assembly so that the second line overlaps with the first line; a locking assembly locking the standard component; adjusting the height of the traveling component using a height adjustment assembly so that the distance between the first marking line and the axis of the segment matches the distance between the first marking line and the center of the first notch; obtaining the distance between each second marking line and the outer surface of the segment, thereby obtaining the line shape dimension of the segment.

[0014] In some embodiments, along the axial direction of the segment, the bottom of the segment has a baseline, the baseline connecting to two ports at both ends of the bottom of the segment. Adjusting the height of the traveling member using the height adjustment component to match the distance between the first marking line and the axis of the segment and the distance between the first marking line and the center of the first notch includes: measuring the distance between the first marking line and the center of the first notch to obtain a first distance; adjusting the height of the traveling member using the height adjustment component and measuring the distance between the first marking line and the baseline to obtain a second distance; and stopping the height adjustment of the traveling member when the sum of the second distance and the radius of the segment matches the first distance.

[0015] In some implementations, the number of measurement positions is multiple, and the multiple measurement positions are arranged side by side at intervals along the axial direction of the segment.

[0016] The beneficial effects of the present invention include at least the following: Since two height adjustment components are respectively located at both ends of the traveling member, the traveling member can be supported by the two height adjustment components, and the height of the traveling member can be adjusted. Since the clamping component is located on the traveling member, the clamping component is supported by the traveling member. Since at least two locking components are located on the clamping component, at least two locking components are supported by the clamping component. Since the standard component is located on the traveling member and is located within the clamping component and the locking component, the standard component has a first notch with an arc-shaped cross-section. The side of the standard component has a first marking line located on a horizontal plane. Along the radial direction of the first notch, the side of the standard component has multiple second marking lines spaced at equal angles. Therefore, when obtaining the segmented line dimensions, each end of the segment has two ports. Along the radial direction of the segment, the segment has a first line. The line connecting the two ports at one end of the segment overlaps with the first line. The first notch has a second line in the radial direction of the notch. The second line is located on the vertical plane. The segment is adjusted so that the two ends of the segment are on the same horizontal plane and the line connecting the two ports at one end of the segment is on the vertical plane. The traveling component reaches the measuring position. The position of the standard component is adjusted in the clamping assembly so that the second line overlaps with the first line. The locking assembly locks the standard component. The position of the standard component is determined along the axial direction of the segment to avoid the standard component's position from shifting. The height of the traveling component is adjusted by the height adjustment assembly so that the distance between the first marking line and the axis of the segment and the distance between the first marking line and the center of the first notch match. The position of the standard component is determined in the height direction. The distance between each second marking line and the outer surface of the segment is obtained, and the line shape dimension of the segment can be obtained. This can ensure high accuracy of the measured line shape dimension and meet the needs of subsequent segment docking and allowance pre-adjustment. Attached Figure Description

[0024] This application is described below with reference to the accompanying drawings and specific embodiments: The segmented measurement method provided in this embodiment aims to at least partially solve the technical problem that the accuracy of the measured linear dimensions is low when using a ruler to measure the local key main body dimensions of a segment, which cannot meet the needs of subsequent segmented docking and allowance pre-adjustment.

(Combined with...) Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The segmented measuring fixture of this embodiment includes: a traveling component 10, a clamping assembly 30, a standard component 50, two height adjustment assemblies 20, and at least two locking assemblies 40. The two height adjustment assemblies 20 are respectively located at both ends of the traveling component 10. The clamping assembly 30 is located on the traveling component 10. At least two locking assemblies 40 are located on the clamping assembly 30. The standard component 50 is located on the traveling component 10 and within the clamping assembly 30 and locking assemblies 40. The standard component 50 has a first notch 501 with a circular arc cross-section. A first marking line 502 is provided on the side of the standard component 50, located on a horizontal plane and along the radial direction of the first notch 501. Multiple second marking lines 503 are provided at equal angular intervals on the side of the standard component 50.

[0026] Multiple second indicator lines 503 are set at evenly spaced angles.

[0027] Since the two height adjustment components 20 are respectively located at both ends of the traveling member 10, the traveling member 10 can be supported by the two height adjustment components 20, and the height of the traveling member 10 can be adjusted. Since the clamping component 30 is located on the traveling member 10, the clamping component 30 is supported by the traveling member 10. Since at least two locking components 40 are located on the clamping component 30, at least two locking components 40 are supported by the clamping component 30. Since the standard component 50 is located on the traveling member 10 and on the clamping component 30 and... Within the locking assembly 40, a first notch 501 is provided on the standard part 50. The cross-sectional shape of the first notch 501 is arc-shaped. A first marking line 502 is provided on the side of the standard part 50, located on a horizontal plane. Along the radial direction of the first notch 501, multiple second marking lines 503 are provided at equal angular intervals on the side of the standard part 50. Therefore, when obtaining the line shape dimensions of the segment, each end of the segment has two ports. Along the radial direction of the segment, the segment has a first line, and the connection between the two ports at one end of the segment is... The line overlaps with the first line. Along the radial direction of the first notch 501, the first notch 501 has a second line. The second line is located on the vertical plane. The segment is adjusted so that the two ends of the segment are on the same horizontal plane and the line connecting the two ports at one end of the segment is on the vertical plane. The traveling component 10 reaches the measuring position. The position of the standard component 50 is adjusted within the clamping assembly 30 so that the second line overlaps with the first line. The locking assembly 40 locks the standard component 50. The position of the standard component 50 is determined along the axial direction of the segment, preventing the position of the standard component 50 from shifting. The height of the traveling component 10 is adjusted by the height adjustment assembly 20 so that the distance between the first marking line 502 and the axis of the segment and the distance between the first marking line 502 and the center of the first notch 501 match. The position of the standard component 50 is determined in the height direction. The distance between each second marking line 503 and the outer surface of the segment is obtained, and the line shape dimension of the segment can be obtained. This ensures high accuracy of the measured line shape dimension and can meet the needs of subsequent segment docking and allowance pre-trimming.

[0028] Figure 6 This is a structural diagram of the moving parts of the segmented measurement fixture. (Combined with...) Figure 6 In some embodiments, to facilitate the movement of the walking component 10 in bringing the standard component 50 to the measurement position, the walking component 10 includes a support frame 101 and two wheel assemblies 102. The support frame 101 supports the clamping assembly 30 and the standard component 50. The two wheel assemblies 102 are respectively located at both ends of the support frame 101. The support frame 101 can be a rigid tube truss structure.

[0029] In some embodiments, the clamping assembly 30 is fixedly mounted on the support frame 101, which supports the clamping assembly 30. The standard part 50 is placed on the support frame 101, which also supports the clamping assembly 30. When the measurement position is to be reached, the support frame 101 moves on the ground via two wheel assemblies 102.

[0030] In some embodiments, the wheel assembly 102 includes at least two casters to facilitate movement of the support frame 101. The number of casters may be two or more.

[0031] Combination Figure 6 In some embodiments, to adjust the height of the standard component 50, the height adjustment assembly 20 includes at least two height adjustment members 201 arranged side-by-side at intervals at the end of the traveling member 10. The number of height adjustment members 201 can be two or more.

[0032] In some embodiments, the height adjustment component 201 can be a screw. A threaded hole is provided on the support frame 101, and the screw is threadedly connected to the threaded hole, allowing it to contact the ground. When adjusting the height of the standard component 50, the screw is rotated to move it towards or away from the ground, thereby adjusting the height of the support frame 101 and thus adjusting the height of the standard component 50. When the traveling component 10 is moving, the screw separates from the ground to avoid interfering with its movement and ensure smooth travel.

[0033] Combination Figure 6 In some embodiments, to facilitate the installation of the standard part 50, the clamping assembly 30 includes two clamping members 301. The two clamping members 301 are arranged side by side and spaced apart on the traveling member 10, and the standard part 50 is disposed between the two clamping members 301. The standard part 50 is clamped by the two clamping members 301 so that the standard part 50 can be placed on the traveling member 10.

[0034] In some embodiments, the distance between the two clamping members 301 is greater than the thickness of the standard member 50, so as to facilitate the adjustment of the position of the standard member 50 in the axial direction of the segment.

[0035] Combination Figure 6 In some embodiments, when the axial position of the standard part 50 is determined in the segment, to prevent the position of the standard part 50 from changing, the locking assembly 40 includes two locking members 401. The two locking members 401 are respectively disposed on the two clamping members 301, and the standard part 50 is disposed between the two locking members 301. The standard part 50 is locked by the two locking members 301 to ensure that the position of the standard part 50 is determined. The two locking members 401 are arranged opposite each other, located on opposite sides of the standard part 50.

[0036] Combination Figure 6 In some embodiments, the locking member 401 includes a mounting portion 4011 and a locking portion 4012. The mounting portion 4011 is disposed on the traveling member 10, and the locking portion 4012 passes through the mounting portion 4011. The mounting portion 4011 can be a mounting base, and the locking portion 4012 can be a screw. The mounting base has a threaded hole, and the screw is threadedly connected to the threaded hole. The screw passes through the threaded hole and abuts against the standard part 50. When the standard part 50 is to be locked, the screw is rotated to move towards the standard part 50, and the two screws abut against the two sides of the standard part 50 respectively, thereby locking the standard part 50.

[0037] Figure 7 A schematic diagram showing the interaction between the moving parts of the segmented measurement fixture and the operating platform; Figure 8 for Figure 7 A cross-sectional view along the CC direction. Combined with... Figure 7 and Figure 8 In some embodiments, due to the large size of the segments, the segment measurement fixture also includes an operating platform 60 with a second notch for easy measurement. The walking component 10 is partially located within the second notch, allowing the operator to stand on the operating platform 60 to perform measurements. The operating platform 60 can be a rigid tube truss structure.

[0038] In some embodiments, to prevent the operating platform 60 from touching the standard part 50, the operating platform 60 is provided with a clearance groove, and the standard part 50 is partially embedded in the clearance groove so that the position of the standard part 50 is determined.

[0039] Combination Figure 7 and Figure 8 In some embodiments, the operating platform 60 is provided with a ladder 70, which allows staff to go up and down the operating platform 60.

[0040] In some embodiments, the bottom of the operating platform 60 is provided with wheels to facilitate movement of the operating platform 60.

[0041] Based on the same inventive concept, this application also provides a segmented measurement method. Based on the segmented measurement fixture, each end of the segment has two ports. Along the radial direction of the segment, the segment has a first line. The line connecting the two ports at one end of the segment overlaps with the first line. Along the radial direction of the first notch 501, the first notch 501 has a second line, which is located on a vertical plane. The segmented measurement method includes: Adjust the segments so that both ends of each segment are on the same horizontal plane.

[0042] Adjust the segments so that the line connecting the two ports at one end of the segment lies on the plumb line.

[0043] The walking component 10 reaches the measurement position.

[0044] The position of the standard part 50 is adjusted within the clamping assembly 30 so that the second line overlaps with the first line, and the locking assembly 40 locks the standard part 50, thus determining the position of the standard part 50 along the axial direction of the segment.

[0045] The height of the walking component 10 is adjusted by the height adjustment component 20 so that the distance between the first marking line 502 and the axis of the segment and the distance between the first marking line 502 and the center of the first notch 501 are matched, thereby determining the position of the standard component 50 in the height direction.

[0046] By obtaining the distance between each second marking line 503 and the outer surface of the segment, the line shape dimension of the segment can be obtained. This ensures high accuracy of the measured line shape dimension and meets the needs of subsequent segment docking and allowance pre-adjustment.

[0047] Since the axis of the segment is located within the segment, it is not easy to obtain the distance between the axis of the segment and the first marking line 502. In some embodiments, along the axial direction of the segment, the bottom of the segment has a baseline, which is connected to two ports at both ends of the bottom of the segment. The height of the traveling member 10 is adjusted by the height adjustment component 20 to match the distance between the first marking line 502 and the axis of the segment and the distance between the first marking line 502 and the center of the first notch 501, including: The distance between the center of the first marking line 502 and the center of the first notch 501 is measured to obtain the first distance.

[0048] The height of the walking component 10 is adjusted by the height adjustment component 20, and the distance between the first marking line 502 and the baseline is measured to obtain a second distance. Since the baseline is located on the outer surface of the segment, it is convenient to obtain the distance between the first marking line 502 and the baseline.

[0049] When the sum of the second distance and the radius of the segment matches the first distance, the height adjustment component 20 stops adjusting the height of the traveling component 10, thus determining the position of the standard component 50 in the height direction.

[0050] In some embodiments, in order to achieve omnidirectional measurement of the segment, there are multiple measurement positions, which are arranged side by side and spaced apart along the axial direction of the segment. The traveling member 10 can move to each measurement position. The standard member 50 realizes the side view of the linear dimensions of each part of the segment. The obtained linear dimensions of the segment have high accuracy and meet the needs of subsequent segment docking and allowance pre-adjustment.
