Description

Technical Field

[0001] The present invention relates to the field of carbon fiber container testing equipment, and particularly to a large-size flange surface simulation device. Background Art

[0002] After the processing of a large-volume carbon fiber storage tank, in order to facilitate installation, a fixed connection flange is usually bonded to the outer surface to facilitate fixing the large-volume carbon fiber storage tank at the actual installation position. Among them, the structure of a large-volume carbon fiber storage tank (when the maximum diameter of the storage tank exceeds 120 cm, it is considered a large-volume carbon fiber storage tank, and the supporting flange is considered a large-size flange) is mostly as shown in the patent with the publication number CN202193262U and the name of seamless aluminum alloy spherical storage tank. The overall storage tank is in a curved spherical shape, and the large-size flange is bonded in the middle area.

[0003] After the container is processed, the connection stability between the flange and the storage tank is a key indicator to measure the use stability of the storage tank. For the test of the flange bonding stability, at present, a sampling inspection method is used to test a single processed storage tank. Specifically, the connection stability between the flange and the storage tank in the radial direction is detected by controlling the air pressure change in the inner tank, and the connection stability of the flange in the axial direction is simulated by pushing and pulling the flange axially. At present, the storage tanks after testing are scrapped, resulting in serious waste of processing resources.

[0004] Based on this, the present application proposes a large-size flange surface simulation device to reduce the waste of processing resources during sampling inspection. Summary of the Invention

Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0027] In the present invention, unless otherwise clearly specified or limited, the first feature being "above" or "below" the second feature may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium.

In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0028] In the present invention, as Figures 1 - 4 shown, there is provided a large-size flange surface simulation device, including a base ring 1. Along the circumferential direction of the outer side of the base ring 1, intermediate arc-shaped plates 2 are arranged at intervals. Between the intermediate arc-shaped plates 2 and the base ring 1, a plurality of first adjustable connecting members arranged along the circumferential direction of the intermediate arc-shaped plates 2 are provided. The first adjustable connecting members can adjust the intermediate arc-shaped plates 2 to deform along the radial direction of the intermediate arc-shaped plates 2; the simulation device further includes side arc-shaped plates 3 arranged on both axial sides of the intermediate arc-shaped plates 2. One end of the side arc-shaped plates 3 abuts against the intermediate arc-shaped plates 2; the simulation device further includes a plurality of second adjustable connecting members arranged at intervals along the side arc-shaped plates 3. The second adjustable connecting members can drive the side arc-shaped plates to deform along the radial direction of the side arc-shaped plates 3.

[0029] When the simulation device of the present invention is in use, a simulation inner tank ring 22 made of the same material as the inner tank of the storage tank is provided, and the contour of the simulation inner tank ring 22 is consistent with the position of the installation flange of the inner tank of the storage tank. The intermediate arc-shaped plates 2 are connected to the outer side of the base ring 1 through the first adjustable connecting members, and the intermediate arc-shaped plates 2 are connected to the inner side of the simulation inner tank ring 22. Then, the side arc-shaped plates 3 are arranged on both sides of the intermediate arc-shaped plates 2 through the second adjustable connecting members, and at the same time, the side arc-shaped plates 3 are connected to the simulation inner tank ring 22.

[0030] At this time, the entire simulation device can be processed by carbon fiber winding together with the same batch of storage tanks. After carbon fiber is wound around the simulation inner tank ring 22 of the simulation device, it is bonded and fixed to the flange.

[0031] During the test, the first adjustable connecting piece can be used to drive the middle arc plate 2 to contract radially along the substrate, so as to drive the simulation inner tank ring 22 to simulate inward contraction through the middle arc plate 2, so as to test the radial connection stability between the flange ring and the storage tank; the second adjustable connecting piece drives the part of the simulation inner tank ring 22 at the flange edge position to contract inward through the side arc plate 3, so as to simulate the deformation difference between the inner tank of the storage tank on the inner side of the flange and the inner tank of the storage tank at the flange edge position, so as to more realistically test the radial connection stability of the flange.

[0032] In the present invention, an external push-pull device (such as an oil cylinder) can be connected to the flange, and the flange can be pushed and pulled by the push-pull device to test the axial connection stability of the flange.

[0033] In the present invention, by adopting a plurality of segmented middle arc plates 2 and a plurality of segmented side arc plates 3 as the connection support structure of the simulation inner tank ring 22, it is convenient to adjust the connection support structure through the first adjustable connecting piece and the second adjustable connecting piece, so that the connection support structure can simulate the inflation and pressurization winding of the storage tank when the simulation inner tank ring 22 is wound with carbon fiber.

[0034] The simulation device of the present invention can only perform carbon fiber winding processing on the flange fixing position during the processing of the same batch of storage tanks, reducing the test loss and improving the processing efficiency of the test pieces. Moreover, the deformation of the simulation inner tank ring can also be adjusted through the first adjustable connecting piece and the second adjustable connecting piece, which is convenient for simulating the connection stability of the flange under different working conditions.

[0035] It should be noted that for the fixing method of the simulation inner tank ring 22 on the middle arc plate 2 and the side arc plate 3, preferably, the simulation inner tank ring 22 is connected to the middle arc plate 2 and the side arc plate 3 by bolts.

[0036] In a preferred embodiment, for the structure of the present invention, further specifically, such as Figure 1As shown, the first adjustable connecting member includes a connecting plate 4 which can be installed on the side of the base ring 1. An outer fixing plate 5 connected to the middle arc-shaped plate 2 is formed at the outer end of the connecting plate 4. The connecting plate 4 is provided with a first fixing hole 6, and the base ring 1 is provided with a second fixing hole 7 corresponding to the position of the first fixing hole 6. At least one of the first fixing hole 6 and the second fixing hole 7 is set as a waist-shaped hole extending along the radial direction of the base ring 1. The simulation device further includes a first bolt 8 which connects the connecting plate 4 and the base ring 1 at the positions of the first fixing hole 6 and the second fixing hole 7.

[0037] As Figure 1 and Figure 2 shown, by fixing the connecting plate 4 on the base ring 1 with the first bolt 8, the connecting plate 4 can be positioned and fixed on the side of the base ring 1 by using the first bolt 8. When the first adjustable connecting member needs to be adjusted radially with respect to the middle arc-shaped plate 2, the connecting plate 4 can be moved by using the moving space of the waist-shaped hole.

[0038] In the illustrated embodiment, the outer fixing plate 5 is connected to the middle arc-shaped plate 2 by bolts.

[0039] In a preferred embodiment, for the structure of the present invention, more specifically, as Figure 2 and Figure 3 shown, an inner fixing plate 9 extending to the inner side of the base ring 1 is formed at the inner end of the connecting plate 4. The simulation device further includes a second bolt 10 which passes through the inner fixing plate 9 and is screwed to the base ring 1. The second bolt 10 is provided with limiting rings 11 on both the inner and outer sides of the inner fixing plate 9.

[0040] As Figure 2 shown, limiting plates are respectively arranged on the upper and lower sides of the inner fixing plate 9 by the second bolt 10, so that the inner fixing plate 9 can be driven to move radially along the base ring 1 by rotating the second bolt 10. Thus, when it is necessary to radially move the connecting plate 4 to adjust the radial deformation of the middle arc-shaped plate 2, the second bolt 10 can be rotated, and the second bolt 10 drives the inner fixing plate 9 to move radially along the base ring 1, and then the connecting plate 4 moves radially, which is convenient for operation.

[0041] For the radial movement of the connecting plate 4, in an alternative embodiment, it can also be set as follows. The base ring 1 is provided with an installation groove 12 at the position of the connecting plate 4. A lead screw 13 extending along the radial direction of the base ring 1 and a slider 14 cooperating with the lead screw 13 are arranged in the installation groove 12. The connecting plate 4 is provided with a plugging portion 15 which is axially inserted and connected with the slider 14 along the base ring 1.

[0042] As Figure 4As shown, when adjusting the connecting plate 4 radially, the slider 14 on the lead screw 13 can be rotated to move radially, and then the connecting plate 4 is driven to move radially by the radial movement of the slider 14, so as to realize the radial movement adjustment of the connecting plate 4.

[0043] As Figure 4 shown, the insertion part 15 is set as an insertion block, and the slider 14 is provided with a slot matching the insertion block.

[0044] In a preferred embodiment, for the structure of the present invention, more specifically, as Figure 2 shown, the second adjustable connecting piece includes a transverse rib plate 16 and a third bolt 17 threadedly installed on the transverse rib plate 16. The transverse rib plate 16 is installed on the part of the connecting plate 4 located outside the base ring 1; a counterbore 18 is provided on the side arc plate 3 corresponding to the third bolt 17, and the outer end of the third bolt 17 extends into the counterbore 18 and forms a limiting block 19.

[0045] As Figure 4 shown, by arranging the transverse rib plate 16 of the second adjustable connecting piece on the connecting plate 4, when simulating the deformation difference between the inner tank of the storage tank inside the flange and the inner tank of the storage tank at the flange edge, first, the middle arc plate 2 (corresponding to the flange position) is radially adjusted. The radial contraction of the connecting plate 4 can synchronously drive the side arc plate 3 to deform radially through the transverse rib plate 16, and then the side arc plate 3 (corresponding to the flange edge position) is driven to deform by adjusting the third bolt 17. In this way, when the side arc plate 3 is radially adjusted, it can be adjusted on the basis of the deformation at the position of the middle arc plate 2, so as to reduce the deformation difference of the simulated inner tank ring 22 in the area between the side arc plate 3 and the middle arc plate 2 caused by adjusting the side arc plate 3 alone, and then prevent the abnormal damage of the simulated inner tank ring 22 deformation caused by this difference.

[0046] In an alternative embodiment, the second adjustable connecting piece can also be directly installed on the base ring 1, such as installing the transverse rib plate 16 on the base ring 1.

[0047] In the illustrated embodiment, in order to facilitate the adjustment of the third bolt 17, the structure of the third bolt 17 is specifically set as that two adjusting nuts are screwed on the inner end of the third bolt 17, and the two adjusting nuts are clamped and fixed on both sides of the transverse rib plate 16, so as to facilitate the adjustment of the positional relationship between the third bolt 17 and the side arc plate 3 and the transverse rib plate 16.

[0048] In a preferred embodiment, for the structure of the present invention, more specifically, as Figure 3 shown, the transverse rib plate 16 includes sub-plate bodies symmetrically arranged on both sides of the connecting plate 4, and a plurality of the third bolts 17 are arranged at intervals along the circumferential direction of the base ring 1 on the sub-plate bodies.

[0049] As Figure 3 shown, this enables the transverse rib plate 16 to be more evenly stressed when loading and deforming the opposite arc plate 3, and at the same time enables the two sides of the connecting plate 4 to be symmetrically stressed, so as to further improve the accuracy of controlling the deformation of the middle arc plate 2 and the side arc plate 3.

[0050] In a preferred embodiment, for the structure of the present invention, more specifically, as Figure 2 and Figure 3 shown, a fixed area extending along the circumferential direction of the side arc plate 3 is formed at the position of the side arc plate 3 corresponding to the countersunk holes 18, and a plurality of threaded holes are provided at intervals on the top surface of the side arc plate 3 in the fixed area.

[0051] As Figure 2 shown, this enables the side arc plate 3 to be deformed under the control of the third bolt 17, and the side arc plate 3 can be deformed under the control of the positions of a plurality of countersunk holes 18, so as to further improve the stability and uniformity of controlling the deformation of the side arc plate 3.

[0052] In a preferred embodiment, for the structure of the present invention, more specifically, as Figure 2 shown, adjacent side arc plates 3 are connected by bolts.

[0053] In a preferred embodiment, for the structure of the present invention, more specifically, as Figure 2 shown, a positioning groove 20 is provided at the position of the base ring 1 corresponding to the connecting plate 4. As Figure 2 shown, by providing the positioning groove 20, this can further guide the radial movement of the connecting plate 4, so as to further improve the stability of controlling the radial deformation of the middle arc plate 2.

[0054] In a preferred embodiment, for the structure of the present invention, more specifically, as Figure 1 shown, the simulation device further includes a support arc plate 21, and the support arc plate 21 is detachably connected to the edge of the side arc plate 3 away from the middle arc plate 2. As Figure 1 shown, by providing the side arc plate 3, after the simulation inner tank ring 22 is fixed on the outer sides of the middle arc plate 2 and the side arc plate 3, the edge of the simulation inner tank ring 22 can be supported by the support arc plate 21, so that the support arc plate 21 can be used for support when the simulation inner tank ring 22 is subjected to carbon fiber winding and flange bonding, so as to maintain the shape stability of the edge position of the simulation inner tank ring 22. When testing, the support arc plate 21 can be removed to prevent the support arc plate 21 from interfering with the deformation of the simulation inner tank ring 22.

[0055] Regarding the fixing method of the supporting arc plate 21, preferably, the supporting arc plate 21 is fixed to the side of the simulated inner tank ring 22 by bolts.

[0056] Each embodiment in this specification is described in a progressive manner. For the same or similar parts among the embodiments, reference can be made to each other. Each embodiment focuses on the differences from other embodiments. In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can refer to the partial description of the method embodiment.
