Description

Technical Field

[0001] The invention relates to the technical field of ship component detection, and in particular to a ship double-walled pipe elastic bracket size measuring tool. Background Art

[0002] On dual-fuel ships, the gas system needs to use double-walled pipes to transmit gas, and the inner and outer pipes of the double-walled pipes need to be supported by elastic brackets. Due to the special nature of the elastic bracket, it is difficult to check it using conventional measuring tools. In addition, during pipeline installation, its contact area with the outer pipe must be greater than 50%. After obtaining the elastic bracket, it needs to be inspected before installation so that problems can be discovered and dealt with in a timely manner to ensure engineering nodes. The existing technology is to assemble the elastic bracket and then perform manual visual inspection, which has low inspection accuracy. If the tolerance of the elastic bracket does not meet the preset standard, it will cause huge hidden dangers during the actual use of the ship. Summary of the invention

[0003] In accordance with the technical problems raised above, a tool for measuring the dimensions of a ship double-walled pipe elastic support is provided.

[0004] The technical means adopted by the present invention are as follows:

[0005] A ship double-walled pipe elastic bracket size measuring tool comprises a first clamping plate and a second clamping plate, which are respectively used to detect the first elastic bracket and the second elastic bracket for the ship double-walled pipe. The first clamping plate and the second clamping plate are provided with detection holes for matching the first elastic bracket and the second elastic bracket, and the inspection holes have a preset margin to inspect the elastic brackets that meet the requirements within a preset range. The first elastic bracket detection hole comprises an upper main body arc portion of the first elastic bracket, an upper diameter-reducing arc portion of the first elastic bracket, a lower turning arc portion, a lower main body arc portion of the first elastic bracket and a lower edge arc portion in sequence. The second elastic bracket detection hole comprises an upper main body arc portion of the second elastic bracket, an upper diameter-reducing arc portion of the second elastic bracket, a first corner portion, a first straight portion, a second corner portion, a lower main body arc portion of the second elastic bracket, a third corner portion and a second straight portion in sequence. The arc surfaces of the upper main body arc portion of the first elastic bracket and the lower main body arc portion of the first elastic bracket face the same direction, and the arc surfaces of the upper main body arc portion of the second elastic bracket and the lower main body arc portion of the second elastic bracket face opposite directions. During inspection, the elastic bracket is inserted into the inspection clamping plate measuring tool to determine whether the elastic bracket is qualified.

[0006] Furthermore, the margin of the thickness H2 of the first elastic support detection hole relative to the elastic support is 0.1 mm.

[0007] Furthermore, the first elastic bracket has an overall length of 101.9 (+2.8, -1) mm, an overall width of 40 (0, -2) mm, and a height of 63.8±2 mm.

[0008] Furthermore, in the first elastic support detection hole, the margin of the lower turning arc portion and the lower edge arc portion relative to the elastic support is ±0.5 mm.

[0009] Furthermore, the margin between the center of the lower turning arc and the center of the arc of the lower main body of the first elastic bracket and the center of the arc of the lower main body of the first elastic bracket and the center of the arc of the lower edge is ±1 mm.

[0010] Furthermore, the overall height of the second elastic bracket is 101.1±4 mm, and the overall width is 40±0.6 mm.

[0011] Furthermore, the main structure of the pallet is made of 304 stainless steel.

[0012] Compared with the prior art, the present invention has the following advantages: the present invention manufactures the inspection pallet according to the elastic bracket, and in order to ensure the strength and durability of the pallet, the main structure of the pallet is made of stainless steel with a thickness of 0.5 mm. It is suitable for measuring multiple batches of elastic brackets, which is convenient and fast without complicated preparation work. At the same time, this tool is suitable for measuring elastic brackets of the same type in other occasions. After obtaining the elastic bracket, the detection work can be completed, and the elastic brackets that do not meet the specifications can be eliminated, reducing the risks that occur after the elastic bracket is installed on the ship.

[0021] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0024] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, the numerical expressions and numerical values ​​do not limit the scope of the present invention. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0025] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention: the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0026] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below their position devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0027] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0028] like Figures 1 to 7As shown, an embodiment of the present invention discloses a ship double-walled pipe elastic bracket size measuring tool, including a first clamping plate and a second clamping plate, which are respectively used to detect the first elastic bracket and the second elastic bracket for the ship double-walled pipe. The first clamping plate and the second clamping plate are provided with detection holes for matching the first elastic bracket and the second elastic bracket, and the inspection holes have a preset margin to inspect the elastic brackets that meet the requirements within a preset range. The first elastic bracket detection hole includes the first elastic bracket upper main body arc portion, the first elastic bracket upper diameter-changing arc portion, the lower turning arc portion, the first elastic bracket lower main body arc portion and the lower edge arc portion in sequence. The second elastic bracket detection hole includes the second elastic bracket upper main body arc portion, the second elastic bracket upper diameter-changing arc portion, the first corner portion, the first straight portion, the second corner portion, the second elastic bracket lower main body arc portion, the third corner portion and the second straight portion in sequence. The arc surfaces of the first elastic bracket upper main body arc portion and the first elastic bracket lower main body arc portion face the same direction, and the arc surfaces of the second elastic bracket upper main body arc portion and the second elastic bracket lower main body arc portion face opposite directions. During inspection, the elastic bracket is inserted into the inspection clamping plate measuring tool to determine whether the elastic bracket is qualified.

[0029] In the corresponding figure, the arc portion R21 of the upper main body of the first elastic bracket is 62 mm, the arc portion R22 of the upper diameter reducing portion of the first elastic bracket is 40.1 mm, and the arc portion R24 of the lower main body of the first elastic bracket is 36.5 mm.

[0030] Furthermore, the margin of the thickness H2 of the first elastic support detection hole relative to the elastic support is 0.1 mm, specifically H2 = 2.5 ± 0.1 mm. The thickness H1 of the second elastic support detection hole is 2.5 mm.

[0031] Furthermore, the overall length L3 of the first elastic bracket is 101.9 (+2.8, -1) mm, the overall width K2 is 40 (0, -2) mm, and the height G3 is 63.8±2 mm.

[0032] Furthermore, in the first elastic support detection hole, the margin of the lower turning arc portion and the lower edge arc portion relative to the elastic support is ±0.5 mm. Specifically, R23=R25=4.5±0.5 mm.

[0033] Furthermore, the margin between the center of the lower turning arc and the center of the arc of the lower main body of the first elastic bracket and the center of the arc of the lower main body of the first elastic bracket and the center of the arc of the lower edge is ±1 mm, specifically L1=L2=42.6±1 mm.

[0034] The distance G2 between the bottom ends of the lower turning arc portion and the lower edge arc portion and the bottom end of the lower main body arc portion of the first elastic bracket is 8±0.1 mm.

[0035] Furthermore, the overall height G1 of the second elastic bracket is 101.1±4 mm, and the overall width K1 is 40±0.6 mm.

[0036] Furthermore, the main structure of the pallet is made of 304 stainless steel.

[0037] The second elastic bracket upper main body arc R11 = 60.75mm, the second elastic bracket upper diameter reducing arc R12 = 46.40mm, the first corner R13, the second corner R14, and the third corner R16 are all 3mm, and the second elastic bracket lower main body arc R15 = 30.40mm.

[0038] The above-mentioned margin means that the elastic bracket within the margin range can meet the requirements of the pallet. If it can be placed in, it means it is adapted and can be used as a qualified part.

[0039] As another optional implementation, holes and other structures may be provided on the card according to the structure of the elastic component to complete the matching detection, such as the holes in the top view.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
