To ensure the safety of the transportation process, the transport containers have high sealing requirements. The transport container is divided into upper and lower parts and is symmetrical in center. It consists of upper and lower half-cylinder components. The sealing of the horizontal transport container after assembly is guaranteed by controlling the processing size and shape and position accuracy of the joint surface of the two half-cylinder components.

It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application and are not used to limit the present application.

[0050] like Figure 1 and Figure 2As shown, according to an embodiment of the present application, a post-welding deformation dimension inspection tool for a semi-cylinder assembly 10 is proposed, comprising: a support 11, a clamping member 12 and a measuring member 13; the semi-cylinder assembly 10 is placed on the support 11, and a first leveling member 15 is provided on the support 11 for leveling the semi-cylinder assembly 10; the clamping member 12 is arranged at both ends of the support 11, and a second leveling member 16 is provided on the clamping member 12 for leveling the semi-cylinder assembly 10; the measuring member 13 is arranged on the semi-cylinder assembly 10 and the clamping member 12, and the clamping member 12 is used to level the measuring member 13, the measuring member 13 is clamped and connected to the support 11, and a reference block 14 is provided on the measuring member 13 for measuring the semi-cylinder assembly 10.

[0051] The post-weld deformation dimension inspection tool for the semi-cylinder assembly 10 provided in the embodiment of the present application comprises a support 11, a clamping member 12 and a measuring member 13. The semi-cylinder assembly 10 is placed on the support 11, and the semi-cylinder assembly 10 is leveled by a first leveling member 15 on the support 11; the measuring member 13 is placed on the semi-cylinder assembly 10 and the clamping member 12, and the measuring member 13 is clamped and fixed to the support 11, and the disassembly and assembly are simple; the measuring member 13 is leveled on the basis of the leveling of the semi-cylinder assembly 10 by a second leveling member 16, and the leveling of the measuring member 13 is completed; the distance between each reference block 14 on the measuring member 13 and the corresponding point to be measured is directly measured to measure the semi-cylinder assembly 10. The post-welding deformation size of the semi-cylinder component 10 provides a measurement reference, and no tools such as a spirit level are required during the measurement process, which simplifies the post-welding measurement process operation steps of the semi-cylinder component 10, realizes the rapid measurement of the comprehensive size of the semi-cylinder component 10 after welding, reduces the workload of the post-welding deformation measurement of the semi-cylinder component 10, and improves the post-welding deformation measurement efficiency of the semi-cylinder component 10; the support 11, the clamping member 12 and the measuring member 13 adopt a split structure, which is easy to disassemble and assemble, easy to operate, and can measure quickly. It is easy to carry or store to the construction site, which reduces the difficulty of on-site inspection, helps to shorten the time spent on on-site inspection of the semi-cylinder component 10, improves overall work efficiency, and speeds up the construction process.

[0052] It can be understood that when measuring, the micrometer needs to pass through the reference block 14, measure the distance from each reference surface (the surface of the reference block 14 facing away from the measuring component 13) to the corresponding measuring point on the measured surface of the semi-cylinder assembly 10, and obtain the deformation size of the semi-cylinder assembly 10 after welding after conversion.

[0053] like Figure 2As shown, in a feasible embodiment, the semi-cylinder assembly 10 includes a cylinder bottom 101, two side plates 102 and a connecting plate 103, and the cylinder bottom 101 and the connecting plate 103 are respectively connected to the two ends of the side plate 102; the measuring member 13 includes three measuring plates, and a reference block 14 is provided on the measuring plate, and a measuring hole is provided on the reference block 14; the first measuring plate 131 is parallel to the cylinder bottom 101, the second measuring plate 132 is parallel to the side plate 102, and the third measuring plate 133 is parallel to the connecting plate 103.

[0054] In this technical solution, after the semi-cylinder assembly 10 is leveled, the measuring member 13 is leveled so that the first measuring plate 131 is parallel to the cylinder bottom 101, the two second measuring plates 132 are respectively parallel to the two side plates 102, and the third measuring plate 133 is parallel to the connecting plate 103, so as to ensure the parallelism of the measuring member 13 and the semi-cylinder assembly 10, and ensure that by measuring the distance between the reference block 14 on the measuring plate and the corresponding point to be measured, the post-weld deformation data of the corresponding position on the semi-cylinder assembly 10 can be accurately obtained, thereby improving the accuracy of the inspection result.

[0055] Furthermore, during measurement, the micrometer needs to be passed through the reference block 14 to measure the distance from each reference surface (the surface of the reference block 14 facing away from its corresponding measuring plate) to the corresponding points on the measured surfaces of the side plate 102, the connecting plate 103, and the bottom 101 of the semi-cylinder assembly 10. After conversion, the deformation size of the semi-cylinder assembly 10 after welding is obtained, which provides a reference for the formulation and adjustment of subsequent machining strategies.

[0056] Furthermore, when the first leveling member 15 is leveling the two sides of the semi-cylinder assembly 10, the level ruler is first placed across the two side plates 102 of the semi-cylinder assembly 10, and then the first leveling members 15 on both sides are adjusted until the bubble in the level ruler is located in the center, and the leveling of the semi-cylinder assembly 10 is completed. When the second leveling member 16 is leveling the measuring member 13, the two pressing members 12 are respectively moved from the connecting plate 103 end and the cylinder bottom 101 end to the two ends of the semi-cylinder assembly 10, and the micrometer is applied to the side plate 102 by the reference block 14 on the two second measuring plates 132 closest to the connecting plate 103 end and the cylinder bottom 101 end, and the second adjusting member is adjusted until the readings of the two micrometers are consistent, and the side plate 102 and the measuring member 13 are leveled. During the measurement process, no tools such as a level ruler are required to cooperate, and the measuring member 13 can be quickly leveled according to the leveled semi-cylinder assembly 10.

[0057] like Figures 2 to 5 As shown, in a feasible implementation manner, the first measurement plate 131 is arranged in parallel with the third measurement plate 133 , and the second measurement plate 132 is arranged vertically between the first measurement plate 131 and the third measurement plate 133 .

[0058] In this technical solution, the first measuring plate 131, the second measuring plate 132 and the third measuring plate 133 are perpendicular to each other, so as to measure the verticality of the bottom 101 and the side plate 102 by measuring the distances from the reference blocks 14 on the first measuring plate 131 and the second measuring plate 132 to the corresponding points to be measured on the bottom 101 and the side plate 102; the second measuring plate 132 is fitted with the side plate 102 after leveling, so as to measure the flatness and length of the side plate 102 by measuring the distances from the reference blocks 14 on the second measuring plate 132 to the corresponding points to be measured on the side plate 102; the distances from the reference blocks 14 on the second measuring plate 132 to the corresponding points to be measured on the side plate 102 are measured; the distances from the reference blocks 14 on the second measuring plate 132 to the corresponding points to be measured on the side plate 102 are measured. 4 to the distance to the corresponding points to be measured on the connecting plate 103 and the side plate 102, and the verticality of the connecting plate 103 and the side plate 102 is measured. The reference block 14 is used as the measurement reference. In the measurement process, without tools such as a level ruler, the key length dimensions and shape and position errors of the semi-cylinder assembly 10 after welding are accurately and quickly measured, that is, the total length of the fastening surface of the semi-cylinder assembly 10, the flatness of the side plate 102, the verticality of the cylinder bottom 101-side plate 102, the verticality of the connecting plate 103-side plate 102 and other comprehensive dimensions are quickly and accurately measured, and multiple key dimensions of the semi-cylinder assembly 10 are quickly inspected, thereby improving the inspection efficiency of the semi-cylinder assembly 10 after welding.

[0059] like Figure 2 and Figure 3 As shown, in a feasible implementation manner, the first measuring plate 131 is arranged along the circumference of the cylinder bottom 101, and the first reference blocks 141 are arranged on the surface of the first measuring plate 131 close to the third measuring plate 133 at equal intervals along the circumference of the first measuring plate 131; the second measuring plate 132 is arranged along the length direction of the side plate 102, and the second reference blocks 142 are arranged on the upper surface of the second measuring plate 132 at equal intervals along the length direction of the second measuring plate 132; the third measuring plate 133 is arranged along the circumference of the connecting plate 103, and the third reference blocks 143 are arranged on the surface of the third measuring plate 133 away from the first measuring plate 131 at equal intervals along the circumference of the third measuring plate 133.

[0060] In this technical solution, the first measuring plate 131 is coaxially arranged with the cylinder bottom 101, and the first reference blocks 141 are arranged at equal intervals on the circumference of the first measuring plate 131, and the distances from the first reference blocks 141 and the second reference blocks 142 to the corresponding points to be measured are measured respectively, so as to measure the verticality between the inner side surface of the cylinder bottom 101 and the side plate 102; the third measuring plate 133 is coaxially arranged with the connecting plate 103, and the third reference blocks 143 are arranged at equal intervals on the circumference of the third measuring plate 133, and the distances from the third reference blocks 143 and the second reference blocks 142 to the corresponding points to be measured are measured, so as to measure the verticality between the outer side surface of the connecting plate 103 and the side plate 102; the distances from the second reference blocks 142 located at both ends of the side plate 102 to the corresponding points to be measured are measured, so as to obtain the flatness of the side plate 102 and the total buckling length of the semi-cylinder assembly 10.

[0061] As a preferred solution, two measuring holes are symmetrically arranged on each reference block 14, and the measuring holes penetrate the measuring plate. The points to be measured of the reference block 14 and the semi-cylinder assembly 10 are measured by inserting a micrometer into the measuring hole.

[0062] In some examples, the first reference blocks 141 are evenly distributed on the first measuring plate 131 in a fan shape along the radial direction of the cylinder bottom 101, and the circumferential interval between two adjacent first reference blocks 141 is 18.5°, so that the inner side of the cylinder bottom 101 is fully covered. Nine first reference blocks 141 are set, and the cylinder bottom 101 has a total of 9×2 first measuring points; the second reference blocks 142 are evenly distributed on the single-side second measuring plate 132 along the length direction of the side plate 102, and the interval between two adjacent second reference blocks 142 is 220 mm, so that the upper surface of the side plate 102 is fully covered. Eleven second reference blocks 142 are arranged on the single-sided second measuring plate 132, and there are 11×2 second measuring points on the single-sided side plate 102. The third reference blocks 143 are evenly distributed on the third measuring plate 133 in a fan shape along the radial direction of the connecting plate 103, and the circumferential interval between two adjacent third reference blocks is 18.5°, so that the outer side surface of the connecting plate 103 is fully covered. Nine third reference blocks 143 are arranged, and there are 9×2 third measuring points on the connecting plate 103, so that the measuring length range reaches 2500mm, and the measurement accuracy of the form and position tolerance is ≤0.1mm.

[0063] like Figure 4 As shown, in a feasible implementation manner, the upper surfaces of the second reference block 142 are all located on the same plane; the surface of the first reference block 141 facing away from the first measuring plate 131 is perpendicular to the upper surface of the second reference block 142; the surface of the third reference block 143 facing away from the third measuring plate 133 is perpendicular to the upper surface of the second reference block 142.

[0064] In this technical solution, the first reference block 141 and the third reference block 143 are finely machined with the upper surface of the second reference block 142 as a reference to ensure verticality, and the surfaces of all reference blocks 14 facing away from the measuring component 13 are finely machined to ensure the flatness of the reference blocks 14 and the accuracy and effectiveness of the measurement results of the reference blocks 14, so as to improve the accuracy of the comprehensive dimensional inspection of the semi-cylinder assembly 10.

[0065] like Figure 4 As shown, in a feasible implementation manner, the lower surface of the second measuring plate 132 is parallel to the upper surface of the second reference block 142 , and a snap-fit ​​stop 134 is provided on the lower surface of the second measuring plate 132 , and the second measuring plate 132 is snap-fitted and connected to the support 11 via the snap-fit ​​stop 134 .

[0066] In this technical solution, the snap-fit ​​stop 134 is used to snap-fit ​​and install the measuring member 13 as a whole with the support 11. The installation surface of the snap-fit ​​stop 134 is finely machined with the upper surface of the second reference block 142 as a reference to ensure the flatness of the second measuring plate 132 and the parallelism between the lower surface and the upper surface, and to ensure that the measuring member 13 can be accurately snap-fitted with the support 11, so that the measuring member 13 is leveled according to the position of the semi-cylinder assembly 10 and the position accuracy of the measuring member 13 is guaranteed.

[0067] like Figure 6 As shown, in a feasible embodiment, the support 11 includes: a first base plate 111, a limit frame 112, a support stop 113, a leveling cantilever 114 and a leveling pad 115; the limit frame 112 is arranged on the first base plate 111, and a V-shaped groove is arranged on the limit frame 112 to accommodate the semi-cylinder assembly 10; the support stop 113 is arranged on the limit frame 112, and the support stop 113 is snap-connected with the measuring member 13; the leveling cantilever 114 is arranged parallel to the first base plate 111, and the first leveling member 15 is vertically arranged on the leveling cantilever 114, and the first leveling member 15 is threadedly connected to the leveling cantilever 114; the leveling pad 115 is arranged above the leveling cantilever 114, and the first leveling member 15 drives the leveling pad 115 to move in a direction perpendicular to the first base plate 111 to level the semi-cylinder assembly 10.

[0068] In this technical solution, the first base plate 111 is arranged along the length direction of the semi-cylinder assembly 10, and the limit frame 112 is used to place and accommodate the semi-cylinder assembly 10. By arranging a V-shaped groove on the limit frame 112, multi-point support of the semi-cylinder assembly 10 can be achieved, so that the support 11 can adapt to semi-cylinder assemblies 10 of different sizes; a leveling cantilever 114 parallel to the first base plate 111 is arranged on the limit frame 112, and the first leveling member 15 is vertically arranged on the leveling cantilever 114. The semi-cylinder assembly 10 is lifted upward by the first leveling member 15 to level the semi-cylinder assembly 10; a support stop 113 is also arranged on the limit frame 112, and the support stop 113 is clamped and connected with the clamping stop 134 to achieve a stable connection between the measuring component 13 and the support 11.

[0069] like Figure 7 As shown, in a feasible implementation manner, a guide portion 116 is provided on the top surface of the leveling cantilever 114 , a guide groove is provided on the leveling pad 115 , and the guide portion 116 is embedded in the guide groove to guide the movement of the leveling pad 115 .

[0070] In this technical solution, the guide portion 116 of the leveling cantilever 114 is embedded in the guide groove of the leveling pad 115, and the guide portion 116 slides in the guide groove to guide the guide groove. When the first leveling member 15 drives the leveling pad 115 to rise and fall, the movement of the leveling pad 115 is guided and limited to prevent the leveling pad 115 from rotating with the first leveling member 15, thereby improving the smoothness and reliability of the movement of the first leveling member 15, allowing the leveling pad 115 to be reset more accurately, which helps to improve the continuity of the leveling operation of the semi-cylinder assembly 10.

[0071] In some examples, the leveling cantilever 114 is welded to the top of the limit frame 112 and extends to both ends of the semi-cylinder assembly 10 to provide installation space for the first leveling member 15; the first leveling member 15 passes upward through the threaded hole at the top of the leveling cantilever 114, and the leveling pad 115 is clamped on the guide portion 116 at the top of the leveling cantilever 114 through the guide groove set in the middle. The first leveling member 15 lifts the leveling pad 115, and the semi-cylinder assembly 10 to be measured is leveled by comprehensively adjusting the heights of the four first leveling members 15.

[0072] like Figure 8 As shown, in a feasible embodiment, the clamping member 12 includes: a second base plate 121 and two support frames 122, the support frames 122 are perpendicular to the second base plate 121, the two support frames 122 are symmetrically arranged on the second base plate 121, and the two support frames 122 are located on both sides of the semi-cylinder assembly 10; the second leveling member 16 is threadedly connected to the support frame 122, and the second leveling member 16 is arranged perpendicular to the second base plate 121 to level the measuring member 13.

[0073] In this technical solution, two clamping members 12 are arranged at both ends of the semi-cylinder assembly 10, and a second leveling member 16 perpendicular to the second base plate 121 is provided on the support frame 122, so that the second leveling member 16 is respectively located at the four corners of the semi-cylinder assembly 10. The measuring member 13 is leveled on the basis of the leveling of the semi-cylinder assembly 10 through the second leveling member 16 to ensure the parallelism of the measuring member 13 and the semi-cylinder assembly 10.

[0074] It can be understood that when the measuring fixture is in working state, the two clamping members 12 are respectively moved from the connecting plate 103 end and the cylinder bottom 101 end into the two ends of the semi-cylinder assembly 10, and the height of the two second measuring plates 132 on the measuring member 13 is adjusted by adjusting the second adjusting member. After the micrometer is used to measure the contact points of the two ends of the second measuring plates 132 and the second leveling member 16 through the reference surface of the measuring member 13 and confirm that they are flush, it is considered that the measuring member 13 is leveled with the semi-cylinder assembly 10, that is, the measuring member 13 has been leveled, and the subsequent comprehensive dimensional measurement of the post-welding deformation of the semi-cylinder assembly 10 can be carried out.

[0075] In a feasible implementation, the second bottom plate 121 is provided with an elongated hole, the support frame 122 is provided with a mounting hole, and the fastener passes through the elongated hole and the mounting hole at the same time, so that the support frame 122 is adjustably connected to the second bottom plate 121 .

[0076] In this technical solution, a long hole is provided on the second bottom plate 121 to facilitate adjusting the position of the support frame 122 on the second bottom plate 121 to adjust the distance between the two support frames 122, and then the support frame 122 and the second bottom plate 121 are fastened together by fasteners to fix the distance between the two support frames 122, so that the clamping member 12 can adapt to semi-cylinder assemblies 10 of different sizes, thereby expanding the scope of application of the tooling and improving practicality.

[0077] Example:

[0078] When the semi-cylinder assembly 10 is measured after welding by the semi-cylinder assembly 10 post-welding deformation dimension inspection tool of the present application, the support 11 is first placed on a flat ground, and the semi-cylinder assembly 10 to be measured is placed in the V-shaped groove of the support 11 by hoisting. The first leveling member 15 and the leveling pad 115 are installed on the leveling cantilever 114, so that the first leveling member 15 is passed upward from the threaded hole at the top of the leveling cantilever 114, and the leveling pad 115 is driven to lift the side plate 102 of the semi-cylinder assembly 10 to level the semi-cylinder assembly 10. The level ruler is placed across the two side plates 102 of the semi-cylinder assembly 10, and then the first leveling member 15 and the height of the leveling pad 115 are adjusted until the bubble in the level ruler is located in the center, and the leveling of the semi-cylinder assembly 10 is completed. Remove the level ruler, and clamp the measuring member 13 with the support stop 113 through the clamping stop 134. Move the clamping member 12 from the connecting plate 103 end and the cylinder bottom 101 end into the two ends of the semi-cylinder assembly 10 respectively, and use the micrometer from the two second reference blocks 142 closest to the connecting plate 103 end and the cylinder bottom 101 end to the side plate 102, and adjust the second leveling member 16 until the readings of the two micrometers are consistent, thereby completing the leveling between the measuring member 13 and the semi-cylinder assembly 10, that is, the leveling of the measuring member 13.

[0079] The micrometer is passed through the first reference block 141, the second reference block 142, and the third reference block 143 in sequence to measure the distances from the surfaces of the cylinder bottom 101, the side plate 102, and the connecting plate 103 to the reference planes on the corresponding reference blocks 14, respectively. Through data processing and calculation, the key length dimensions of the semi-cylinder assembly 10 after welding, i.e., the total length of the fastening surface, and the form and position errors, i.e., the flatness of the side plate 102, the verticality of the cylinder bottom 101-side plate 102, the verticality of the connecting plate 103-side plate 102 and other comprehensive dimensions are obtained.

[0080] like Fig. 9 As shown in the figure, when measuring the flatness of the side panels, for the two side panels, the distances Lcn from the 11 second reference blocks on the third measuring plate to the corresponding measuring points on the side panels are measured respectively, and the flatness Sp of the single-side side panel is calculated according to formula ①:

[0081] Side plate flatness: Sp = |(Lcn)max-(Lcn)min|①

[0082] like Fig.10 As shown in the figure, when measuring the verticality between the bottom of the cylinder and the side plate, and the verticality between the connecting plate and the side plate, for the connecting plate and the bottom of the cylinder, measure the distance Ltn / Lbn from the 9 first reference blocks / third reference blocks on the first measuring plate / third measuring plate to the corresponding measuring points on the measuring surface, respectively. The verticality Sz between the bottom of the cylinder / connecting plate and the side plate is calculated according to formulas ② and ③:

[0083] Verticality of cylinder bottom and side plate: Sz=|(Ltn)max|+Sp ②

[0084] Verticality of connecting plate-side plate: Sz=|(Lbn)max|+Sp ③

[0085] like Fig.11 As shown, when measuring the total length of the fastening surface, the length of the measuring component has been determined as L through measurement, and the total length of the fastening surface Sc is calculated according to formula ④:

[0086] Total length of the fastening surface: Sc = L-Lbn+Ltn④
