Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of measuring tools, in particular to a measuring tool for the dimensions of the welding ring of the SIA interface of centrifugal ductile iron pipes. Background Art
[0002] Centrifugal ductile iron pipes are high-quality cast iron pipes, mainly used for water supply, drainage and gas transmission pipelines. They are manufactured through a special centrifugal casting process and have excellent mechanical properties and corrosion resistance. The SIA interface of centrifugal ductile iron pipes is a special interface form used to connect centrifugal ductile iron pipes, usually used in occasions where high-strength connections are required. By using rubber ring seals and flanges or clamps for fixation, the SIA interface can ensure the sealing performance and strength of the pipe connection.
[0003] As a specific component in the SIA interface structure, the welding ring can play the roles of strengthening the connection, transmitting force, and fixing the rubber ring. After the welding of the welding ring is completed, it is necessary to detect its size and position to determine whether it is accurately welded at the set position on the ductile iron pipe. Usually, it is necessary to detect the width, height of the welding ring and its distance from the socket. In the prior art, vernier calipers are generally used to detect these three dimensions respectively and judge whether their sizes meet the standards. For each welding ring, it needs to be measured three times and judged three times, and the detection efficiency is relatively low. Content of the Utility Model
[0004] The utility model provides a measuring tool for the dimensions of the welding ring of the SIA interface of centrifugal ductile iron pipes to solve the technical problem of relatively low detection efficiency when detecting the size and position of the welding ring in the prior art.
[0005] To solve the above problems, the following technical solutions are adopted for a measuring tool for the dimensions of the welding ring of the SIA interface of centrifugal ductile iron pipes provided by the utility model:
[0006] A measuring tool for the dimensions of the welding ring of the SIA interface of centrifugal ductile iron pipes includes a detection card board in an L shape, which is arranged in a horizontal plane. The detection card board includes a positioning board section and a detection board section that are perpendicular to each other. Both the positioning board section and the detection board section are square. The positioning board section extends along the left-right direction, and the detection board section extends along the front-back direction. The positioning board section is connected to the rear side of the detection board section and is located at the right end of the detection board section. A card slot for the welding ring on the ductile iron pipe to be inserted into is provided on the rear side of the detection board section. The card slot is U-shaped. The size of the card slot in the left-right direction is used to detect the width of the welding ring, the size of the card slot in the front-back direction is used to detect the height of the welding ring, and there is a set distance between the card slot and the positioning board section, and this distance size is used to detect the distance between the welding ring and the end face of the ductile iron pipe.
[0007] With the above technical solution, when it is necessary to determine whether the size and welding position of the welding ring on the ductile iron pipe are accurate, the detection card board is clamped outside the ductile iron pipe. The left side of the positioning plate section is abutted against the end face of the ductile iron pipe, and the rear side of the detection plate section is abutted against the outer wall of the ductile iron pipe. Check whether the welding ring can be inserted into the card slot. If the welding ring can be inserted into the card slot, and the width dimension and height dimension of the welding ring respectively match the dimensions of the card slot in the left-right and front-back directions, it is determined that the size and welding position of the welding ring are accurate and it belongs to a qualified part. If the welding ring cannot be inserted into the card slot, it is determined that there is a problem with the welding position or width dimension of the welding ring, and it belongs to an unqualified part. The welding ring needs to be cut off and re-welded. If the welding ring can be inserted into the card slot, but a large gap can be observed between the welding ring and the slot wall of the card slot, it also indicates that the size of the welding ring does not meet the requirements and it belongs to an unqualified part.
[0008] Further, a plurality of card slots arranged at intervals in the left-right direction are provided at the rear side of the detection card board, and the dimensions of each card slot in the left-right direction are different, and the dimensions of each card slot in the front-back direction are different.
[0009] With the above technical solution, the detection card board can be applied to detect the welding rings on ductile iron pipes of different specifications, and the applicable range is wider.
[0010] Further, the positioning plate section and the detection plate section are integrally formed.
[0011] With the above technical solution, the detection card board is easier to manufacture.
[0012] Further, the length dimension of the positioning plate section is smaller than the length dimension of the detection plate section.
[0013] With the above technical solution, the positioning card board does not need to be made too long, saving materials and having a lower production cost.
[0014] Further, the width dimension of the positioning plate section is smaller than the width dimension of the detection plate section.
[0015] With the above technical solution, since a card slot is provided on the detection card board, making its width wider can improve its structural strength.
[0016] Further, a positioning plate block is connected to the left side of the positioning plate section, and the positioning plate block is perpendicular to the positioning plate section.
[0017] With the above technical solution, the detection card board is positioned by abutting the positioning plate against the end face of the ductile iron pipe. The area of the positioning surface is larger, the positioning is more accurate, and the detection result is more accurate.
[0018] Further, arc chamfers are provided at the right-angle tips of the detection card board.
[0019] Adopting the above technical solution, an arc chamfer is provided at the tip of the detection card board, making it safer to use.
[0020] The beneficial effects of a size measuring tool for the SIA interface welding ring of a centrifugal ductile iron pipe provided by the present utility model are as follows: Using the detection card board to detect the welding ring on the ductile iron pipe, it is possible to determine at one time whether the width dimension, height dimension of the welding ring and the spacing dimension between the welding ring and the end face of the ductile iron pipe are accurate, and the detection efficiency is higher.

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the present utility model.
[0028] The following are embodiments of a size measuring tool for the SIA interface welding ring of a centrifugal ductile iron pipe provided by the present utility model:
[0029] As Figure 1 shown, a size measuring tool for the SIA interface welding ring of a centrifugal ductile iron pipe includes a detection card board 1 and a positioning plate block 2.
[0030] The detection card board 1 is L-shaped and is a horizontally arranged flat plate. The detection card board 1 includes a positioning plate section 102 and a detection plate section 101 that are perpendicular to each other. Both the positioning plate section 102 and the detection plate section 101 are rectangular. The positioning plate section 102 extends in the front-back direction, and the detection plate section 101 extends in the left-right direction. The positioning plate section 102 is connected to the rear side of the detection plate section 101 and is located at the right end of the detection plate section 101. A positioning plate block 2 is vertically connected to the left side of the positioning plate section 102. The left side plate surface of the positioning plate block 2 is a positioning surface for being attached to the end surface of the ductile iron pipe 3.
[0031] Two card slots 103 are provided at the rear side of the detection plate section 101 and are arranged at intervals in the left-right direction. Both card slots 103 are U-shaped and have openings facing backward. The sizes of the two card slots 103 in the left-right direction are different, and the sizes in the front-back direction are also different. The sizes of the two card slots 103 in the left-right direction are respectively equal to the standard width sizes of the welding rings 4 on the ductile iron pipes 3 of corresponding specifications. The sizes of the two card slots 103 in the front-back direction are respectively equal to the standard height sizes of the welding rings 4 on the ductile iron pipes 3 of corresponding specifications. The distance dimensions of the two card slots 103 from the positioning surface are respectively equal to the standard dimensions of the welding rings 4 from the end surface of the ductile iron pipe 3 of corresponding specifications. The equality here means that the respective dimensions of the card slots 103 are within the standard tolerance ranges of the respective parameter dimensions of the welding rings 4, rather than being exactly equal.
[0032] Arc-shaped chamfers are provided at all right-angle sharp corners of the detection card board 1, making it safer to use.
[0033] When the utility model is in use, the card board is clamped on the ductile iron pipe 3. As Figure 3 shown, the positioning surface of the positioning plate block 2 is made to fit with the end surface of the ductile iron pipe 3, and the rear side of the detection plate section 101 is made to fit with the pipe wall of the ductile iron pipe 3. Check whether the welding ring 4 can be inserted into the corresponding card slot 103. If the welding ring 4 can be inserted into the card slot 103, and the width dimension and height dimension of the welding ring 4 respectively match the dimensions of the card slot 103 in the left-right and front-back directions, it is determined that the dimensions and welding position of the welding ring 4 are accurate and it belongs to a qualified part. If the welding ring 4 cannot be inserted into the card slot 103, it is determined that there is a problem with the welding position or width dimension of the welding ring 4 and it belongs to an unqualified part, and the welding ring 4 needs to be cut off and re-welded. If the welding ring 4 can be inserted into the card slot 103, but it can be observed that there is a large gap between the welding ring 4 and the slot wall of the card slot 103, or the welding ring 4 significantly protrudes from the card slot 103, it indicates that the width dimension or height dimension of the welding ring 4 does not meet the requirements and it belongs to an unqualified part.
[0034] The utility model can detect three parameters of the welding ring 4 on the ductile iron pipe 3 at one time, with higher detection efficiency.
[0035] In this embodiment, two card slots 103 are provided on the detection plate section 101. In other embodiments, only one card slot 103 is provided on the detection plate section 101. At this time, the structure of the detection card plate 1 is as Figure 2 shown. At this time, the detection card plate 1 can only detect ductile iron pipes 3 and welding rings 4 of one specification.
[0036] In this embodiment, a positioning plate section 2 is vertically connected to the left side of the positioning plate section 102. In other embodiments, the positioning plate section 2 is not provided. At this time, the positioning plate section 102 is made to fit the end face of the ductile iron pipe 3 to position the detection card plate 1.
[0037] Based on the above description of this specification, those skilled in the art can also understand the following terms used, such as the terms indicating orientation or positional relationship, such as "upper", "lower", "front", "rear", "left", "right", "width", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationship shown in the drawings of this specification. It is only for the purpose of facilitating the description of the solution of the present invention and simplifying the description, rather than explicitly or implicitly indicating that the device or element involved must have the specific orientation, be constructed and operate in the specific orientation. Therefore, the above terms of orientation or positional relationship cannot be understood or interpreted as a limitation to the solution of the present invention.
[0038] In addition, in the description of this specification, the meaning of "a plurality of" is at least two, such as two, three or more, etc., unless otherwise specifically and clearly defined.
