Description

Technical Field

[0001] This utility model relates to the technology for preparing liquefied argon film tanks, specifically to a tooling for detecting the gap between the sliding anchor plate of a liquefied argon film tank. Background Technology

[0002] Liquefied argon membrane tanks are large, low-pressure storage tanks. Their internal temperature is lower than that of liquefied natural gas. The tanks contain numerous membrane insulation panels, reinforced at the bottom and top with foam-bonded plywood, and fitted with accessories. (Specific details are as follows...) Figure 1 and Figure 2 As shown, the membrane tank insulation board includes a reinforced foam layer 1 and a plywood 2 disposed on the reinforced foam layer 1. The plywood 2 has several fixing grooves 5. A sliding anchor plate 3 is installed in the fixing groove 5. The sliding anchor plate 3 is movably disposed in the fixing groove 5. There needs to be a omnidirectional gap space between the sliding anchor plate 3 and the fixing groove 5. That is to say, when the sliding anchor plate 3 is located at the center of the fixing groove 5, the sliding anchor plate 3 can slide in any direction within the fixing groove 5 within a certain gap range.

[0003] Because adhesive may overflow between the reinforced foam layer 1 and the plywood 2, and this adhesive, once cured, will affect the space between the sliding anchor plate 3 and the mounting groove 5, preventing the sliding anchor plate 3 from sliding within the mounting groove 5 in any direction within the specified gap range, it is necessary to inspect the gap between the sliding anchor plate 3 and the mounting groove 5 to ensure that the sliding anchor plate 3 does not have the above-mentioned problem. The existing method is to measure it by inserting a vernier caliper. This measurement and inspection method has many drawbacks, as follows:

[0004] 1. The vernier caliper needs to be inserted between the sliding anchor plate 3 and the anchor plate groove 5 to measure multiple positions, which is time-consuming, labor-intensive and inefficient.

[0005] 2. The point measurement method of the vernier caliper cannot achieve all-round detection. On the one hand, it is impossible to cover all points, and on the other hand, the vernier caliper cannot be inserted into the bottom edge area of ​​the solid plate groove 5, so it is impossible to measure the gap range in this area, resulting in the accuracy of the detection results being less than ideal. Summary of the Invention

[0006] Purpose of the invention: In order to overcome the shortcomings of the existing technology, a tooling for detecting the gap of the sliding anchor plate of the liquefied argon film tank is provided. It can complete the gap detection in one go, simply and quickly, which not only greatly improves the detection efficiency, but also ensures that all-round detection is achieved and guarantees the accuracy of the detection results.

[0007] Technical Solution: To achieve the above objectives, this utility model provides a tooling for detecting the gap of a sliding anchor plate in a liquefied argon film tank. The tooling includes a detection cylindrical rod, which comprises an operating part, an upper limit detection part, and a lower limit detection part. The upper limit detection part and the lower limit detection part are located at opposite ends of the operating part. The cross-sectional diameters of the upper limit detection part and the lower limit detection part are respectively matched to the upper and lower limits of the acceptable gap range of the sliding anchor plate. The upper limit detection part and the lower limit detection part are used to detect whether the upper and lower limits of the gap between the sliding anchor plate and the plywood are acceptable.

[0008] Furthermore, the surface of the operating part has a carved grid structure to increase friction and make it easier to grip for testing.

[0009] Furthermore, the operating part and the upper limit detection part have the same cross-sectional diameter, which facilitates molding.

[0010] Furthermore, the operating unit, the upper limit detection unit, and the lower limit detection unit are integrally formed.

[0011] Furthermore, the operation unit, the upper limit detection unit, and the lower limit detection unit are coaxial.

[0012] Furthermore, the edges of the insertion surfaces of the upper limit detection unit and the lower limit detection unit are rounded to prevent damage to the sliding anchor plate and the mounting plate groove when the upper limit detection unit and the lower limit detection unit are inserted for detection.

[0013] Furthermore, the upper and lower limits of the qualified gap range of the sliding anchor plate are a and b, respectively, and the cross-sectional diameters of the upper limit detection part and the lower limit detection part are a+0.1mm and b, respectively.

[0014] Furthermore, a heat protection plate is provided at the bottom of the sliding anchor plate, which can protect the sliding anchor plate and make the sliding anchor plate easier to move.

[0015] Beneficial effects: Compared with the prior art, this utility model designs a special tooling to replace the vernier caliper. The specific size design of its upper limit detection part and lower limit detection part can realize the detection by inserting the detection cylindrical rod into the gap between the sliding anchor plate and the plate groove and rotating it one revolution. The whole operation is very simple, convenient and fast, and can complete a detection within 5 seconds, which greatly improves the efficiency of gap detection. Moreover, it can ensure all-round detection, guarantee the accuracy and comprehensiveness of the detection results, and ensure the detection effect. Attached Figure Description

[0020] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention. After reading the present invention, any modifications of the present invention in various equivalent forms by those skilled in the art will fall within the scope defined by the appended claims.

[0021] like Figure 1 and Figure 2 As shown, the insulating plate of the liquefied argon membrane tank includes a reinforced foam layer 1 and a plywood 2 bonded to the reinforced foam layer 1 with adhesive. The plywood 2 is provided with anchoring strips 6 and three mounting slots 5. Each mounting slot 5 is equipped with a sliding anchoring plate 3, which is movably installed in the mounting slot 5. A heat protection plate 4 is provided at the bottom of the sliding anchoring plate 3. According to the design requirements, when the sliding anchoring plate 3 is located in the center position in the mounting slot 5, the distance between the sliding anchoring plate 3 and the wall of the mounting slot 5 needs to be 2.75 to 3.5 mm. That is to say, when the sliding anchoring plate 3 slides to one end close to the wall of the mounting slot 5, the distance between the sliding anchoring plate 3 and the wall of the mounting slot 5 needs to be 5.5 to 7.0 mm.

[0022] like Figure 3 As shown, this utility model provides a tooling for detecting the gap of the sliding anchor plate of a liquefied argon film tank. The tooling includes a detection cylindrical rod, which is composed of an operating part 7, an upper limit detection part 8, and a lower limit detection part 9. The upper limit detection part 8 and the lower limit detection part 9 are located at opposite ends of the operating part 7. The surface of the operating part 7 has a carved grid structure. The operating part 7 and the upper limit detection part 8 have the same cross-sectional diameter. The operating part 7, the upper limit detection part 8, and the lower limit detection part 9 are integrally formed and are coaxial. The edges of the insertion surfaces of the upper limit detection part 8 and the lower limit detection part 9 have rounded corners. The cross-sectional diameters of the upper limit detection part 8 and the lower limit detection part 9 are 7.1 mm and 5.5 mm, respectively.

[0023] like Figure 4 As shown, this embodiment will Figure 3 The tooling pair shown Figure 2 The sliding anchor plate gap of the insulating plate of the liquefied argon thin-film tank shown is tested. The specific testing method is as follows:

[0024] First, push the sliding anchor plate 3 to one side of the mounting groove 5 so that the sliding anchor plate 3 partially fits the mounting groove 5. Then, hold the operating part 7 and insert the lower limit detection part 9 into the gap between the sliding anchor plate 3 and the mounting groove 5. Next, slide the lower limit detection part 9 along the mounting groove 5. If it can smoothly complete one circle, it means that the maximum gap between the sliding anchor plate 3 and the mounting groove 5 exceeds 5.5mm; otherwise, it means that it is less than 5.5mm and the gap test is unqualified.

[0025] Then, remove the lower limit detection part 9, keep the sliding anchor plate 3 at the edge, and try to insert the upper limit detection part 8 into the gap between the sliding anchor plate 3 and the plate groove 5. If the upper limit detection part 8 cannot be inserted, it means that the maximum gap between the sliding anchor plate 3 and the plate groove 5 is less than 7.1mm; if it can be inserted, it means that the maximum gap between the sliding anchor plate 3 and the plate groove 5 is greater than 7mm, and the gap test is unqualified.

[0026] If both the lower limit detection section 9 and the upper limit detection section 8 pass the test, it means that the maximum gap between the sliding anchor plate 3 and the anchor plate groove 5 is between 5.5 and 7.0 mm, and the final test result is qualified.

[0027] As can be seen from the above detection process, the entire operation is very simple, convenient and quick, and can complete a detection within 5 seconds, which greatly improves the efficiency of gap detection. Moreover, it can ensure all-round detection, guarantee the accuracy and comprehensiveness of the detection results, and ensure the detection effect.
