Description

[0002] In a shipyard, ship component assembly refers to the process of combining and installing various hull structures, equipment, pipelines, electrical components and the like according to design drawings and technical requirements. It is one of the core links of shipbuilding and directly affects the quality, performance and construction period of the ship. Among them, when assembling the pipeline, the pipeline needs to be welded and connected with the flange. Generally, the pipeline is inserted into the inner port of the flange, and according to the pipeline assembly and welding requirements, the reserved size of the flange (i.e. the distance between the end face of the pipeline inserted into the inner port of the flange and the outer end face of the inner port of the flange) is equal to the wall thickness of the pipeline, that is, the weld forms an isosceles right triangle after welding, so as to achieve the best effective welding strength.

[0031] As shown, Figs. 1-3 The auxiliary tool for connecting the flange and the pipeline includes a clamping piece 1 and a measuring piece 2. The clamping piece 1 includes a first clamping part 11 and a second clamping part 12 connected in an L-shaped right angle.

The first clamping part 11 is configured to extend into the pipeline, and the side of the first clamping part 11 facing the clamping groove 13 is in abutment with the inner wall of the pipeline. The side of the second clamping part 12 facing the clamping groove 13 is configured to be in abutment with the end face of the flange. The measuring piece 2 is adjustably arranged on the clamping piece 1 along the direction of the intersection line of the first clamping part 11 and the second clamping part 12. The measuring piece 2 is provided with a measuring end 21 located in the clamping groove 13. The measuring end 21 is provided with a first scale edge 211 and a second scale edge 212 connected in a right angle. The scale size of the intersection of the first scale edge 211 and the first clamping part 11 is the same as the scale size of the intersection of the second scale edge 212 and the second clamping part 12.

The second scale edge 212 is perpendicular to the second clamping part 12 and can be in abutment with the side wall of the inner opening of the flange.

[0032] When assembling the pipeline, first, according to the wall thickness of the pipeline, the position of the measuring piece 2 is adjusted along the direction of the joint line of the first clamping part 11 and the second clamping part 12, so that the measuring end 21 is overlaid above the clamping groove 13, the scale line intersected by the first scale edge 211 and the first clamping part 11 is the size of the wall thickness of the pipeline, at this time, the scale line intersected by the second scale edge 212 and the second clamping part 12 is also the size of the wall thickness of the pipeline, then one end of the pipeline is inserted into the inner opening of the flange, and the first clamping part 11 is inserted into the pipeline, so that the side of the first clamping part 11 facing the clamping groove 13 abuts against the inner wall of the pipeline, at the same time, the side of the second clamping part 12 facing the clamping groove 13 abuts against the end face of the flange, and the second scale edge 212 abuts against the side wall of the inner opening of the flange, then the position of the pipeline in the inner buckle of the flange is adjusted, so that the end face of the pipeline abuts against the first scale edge 211, at this time, the distance between the end face of the flange and the end face of the pipeline is the wall thickness of the pipeline, that is, the reserved size of the flange is equal to the wall thickness of the pipeline, so that the pipeline meets the assembly requirements. The auxiliary tool has simple structure and convenient operation, by setting the first clamping part 11 and the second clamping part 12 connected at right angles, and cooperating with the first scale edge 211 and the second scale edge 212, the scale size intersected by the first scale edge 211 and the first clamping part 11 can be adjusted according to the wall thickness of the pipeline actually used, so that the scale size of the second scale edge 212 is equal to the wall thickness of the pipeline, so as to limit the size of the reserved edge of the flange, ensure the accuracy of the reserved size of the flange, and improve the working efficiency of the pipeline assembly.

[0033] It should be noted that the first clamping part 11 and the second clamping part 12 are connected at right angles, the first clamping part 11 intersects with the second clamping part 12, and the joint line of the first clamping part 11 and the second clamping part 12 is the line connecting the two intersection points A and B (as shown in Fig. 2

[0034] Optionally, as Figs. 1-3 ​As shown, the auxiliary tool for flange and pipe connection further comprises a first plug-in piece 3 and a first fastener. The clamping piece 1 is provided with a through hole 1 4 located on the intersection line of the first clamping part 1 1 and the second clamping part 12. The measuring piece 2 is provided with a strip-shaped hole 22 extending along the intersection line of the first clamping part 1 1 and the second clamping part 12. The first plug-in piece 3 penetrates the strip-shaped hole 22 and the through hole 1 4 and is threadedly connected with the first fastener. When adjusting the position of the measuring piece 2, first, the scale size of the first scale edge 21 1 is determined according to the wall thickness of the pipe, the measuring piece 2 is moved along the intersection line of the first clamping part 1 1 and the second clamping part 12, so that the determined scale size of the first scale edge 21 1 intersects with the side of the first clamping part 1 1 facing the clamping groove 13, at this time, the scale size of the second scale edge 21 2 intersecting with the second clamping part 12 is also the wall thickness of the pipe, then the first plug-in piece 3 penetrates the strip-shaped hole 22 and the through hole 1 4 and is threadedly connected with the first fastener, thereby completing the adjustment of the position of the measuring piece 2 and facilitating the subsequent assembly of the pipe.

[0035] In the embodiment, the hole diameter of the through hole 1 4 is 6 mm, and the scale range of the first scale edge 21 1 and the scale range of the second scale edge 21 2 are 30 mm. In other embodiments, the hole diameter of the through hole 1 4 can be set to other sizes, and the scale range of the first scale edge 21 1 and the scale range of the second scale edge 21 2 can be set to other ranges according to actual needs, which are not limited here.

[0036] Exemplarily, the first plug-in piece 3 comprises a butterfly bolt, and the first fastener comprises a fastening nut.

[0037] In some embodiments, the auxiliary tool for flange and pipe connection further comprises a second plug-in piece and a second fastener. The clamping piece 1 is provided with a through hole 2 located on the intersection line of the first clamping part 1 1 and the second clamping part 12. A plurality of through holes 3 are provided on the measuring piece 2 in a spaced manner along the intersection line of the first clamping part 1 1 and the second clamping part 12. The second plug-in piece penetrates the through hole 2 and the through hole 3 opposite to the through hole 2 and is threadedly connected with the second fastener. When adjusting the position of the measuring piece 2, first, the scale size of the first scale edge 21 1 is determined according to the wall thickness of the pipe, the measuring piece 2 is moved along the intersection line of the first clamping part 1 1 and the second clamping part 12, so that the determined scale size of the first scale edge 21 1 intersects with the side of the first clamping part 1 1 facing the clamping groove 13, at this time, the scale size of the second scale edge 21 2 intersecting with the second clamping part 12 is also the wall thickness of the pipe, then the second plug-in piece penetrates the through hole 2 and the through hole 3 opposite to the through hole 2 and is threadedly connected with the second fastener, thereby completing the adjustment of the position of the measuring piece 2 and facilitating the subsequent assembly of the pipe.

[0038] Exemplarily, the second plug-in piece comprises a bolt, and the second fastener comprises a fastening nut.

[0039] Optionally, such as Figs. 1-3 As shown, the snap-fit ​​component 1 is provided with two guide barriers 5. The two guide barriers 5 are symmetrically distributed about the boundary line between the first snap-fit ​​portion 11 and the second snap-fit ​​portion 12. The two guide barriers 5 form a limiting cavity 51, and the measuring component 2 is disposed within the limiting cavity 51. The measuring component 2 is provided with a first inclined side and a second inclined side, which slide in contact with the inner walls of the two guide barriers 5 respectively. When it is necessary to adjust the position of the measuring component 2, the measuring component 2 is moved along the boundary line between the first snap-fit ​​portion 11 and the second snap-fit ​​portion 12. During this process, the first inclined side and the second inclined side of the measuring component 2 will slide along the inner walls of the two guide barriers 5 respectively. By setting two symmetrically distributed guide barriers 5, a limiting cavity 51 is formed, ensuring that the measuring element 2 is always located within the limiting cavity 51. This provides a limiting effect on the measuring element 2, preventing it from deviating during movement and improving motion accuracy. Furthermore, the first and second inclined edges of the measuring element 2 slide along the inner wall of the guide barriers 5, which provide guidance, ensuring that the measuring element 2 always moves along the extension direction of the guide barriers 5 (i.e., along the boundary line between the first locking part 11 and the second locking part 12). In addition, by setting the first inclined edge, the measuring element 2 can avoid the inner wall of the pipe and the inner opening of the flange, facilitating the insertion of the first scale edge 211 of the measuring element 2 into the inner opening of the flange and abutting against the pipe end face.

[0040] Optionally, a limiting member is provided at the upper end of the guide barrier 5, and the limiting member extends along the extension direction of the guide barrier 5. The limiting member and the side of the guide barrier 5 facing the limiting cavity 51 form a sliding cavity, and sliding engaging members are provided at both the first and second inclined sides, which can be slidably engaged in the sliding cavity. By providing the limiting member and the sliding engaging members, the connection strength between the guide barrier 5 and the measuring element 2 can be improved, preventing the measuring element 2 from detaching from the two guide barriers 5, and enhancing the stability of the overall structure.

[0041] In this embodiment, the limiting member includes a first bend and a second bend that are connected at an angle. The end of the first bend away from the second bend is connected to the guide barrier 5, and the guide barrier 5, the first bend, and the second bend form a sliding cavity.

[0042] Optionally, the arc transition between the first and second bends can prevent stress concentration in the transition area, which could lead to breakage and failure of the limiting component, and can also prevent scratches to the operator. Furthermore, it can prevent wear between the transition area and the sliding latch.

[0043] Obviously, the above embodiments of the present application are merely exemplary but not intended to limit the embodiments of the present application. Various obvious changes, re-adjustments and substitutions can be made by those skilled in the art without departing from the scope of the present application. It is not necessary or possible to enumerate all the embodiments. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the claims of the present application.
