[0027] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. However, if it is indicated as a direct connection, it means that the two connected bodies are not connected through an intermediate structure, but are only connected to form a whole through a connecting structure. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0028] In the present invention, unless otherwise clearly specified and limited, the first feature "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0029] In the present invention, Figure 1-5 As shown, a liner support device for tank winding is provided, which is used to support a tank liner 1, wherein the tank liner 1 has an opening, and the opening of the tank liner 1 is provided with a connecting structure, and the support device comprises: a first support 2, wherein the first support 2 comprises a first rotating ring 3 which can be connected to the connecting structure, and the first rotating ring 3 is arranged to be rotatable; an upper support, wherein the upper support comprises a second rotating ring 5 which can be connected to the connecting structure, and the second rotating ring 5 is arranged to be rotatable; a core rod 6, wherein the core rod 6 can pass through at least one of the second rotating ring 5 and the first rotating ring 3 and extend into the inner side of the tank liner 1, and the core rod 6 is provided with a plurality of wireless ranging sensors 7 at intervals along its length direction, and the core rod 6 is arranged to be relatively rotatable with the second rotating ring 5 and the first rotating ring 3 at corresponding positions.

[0030] When the supporting device of the present invention is used, the tank liner 1 is placed between the upper support and the first support 2, and the upper support and the first support 2 are respectively connected to the connecting structures at corresponding positions, and the core rod 6 extends into the inner side of the tank liner 1.

[0031] In a non-pressurized natural state, the tank liner 1 is driven to rotate by the upper support and the first support 2, and the core rod 6 and the tank liner 1 are made to rotate relative to each other. The wireless distance measuring sensor 7 on the core rod 6 can perform distance sampling on specific points corresponding to the tank liner 1 (multiple specific points are set on the circumference of the tank liner 1 corresponding to the same wireless distance measuring sensor 7), so as to construct a primary database of the tank liner 1.

[0032] At this time, the inner side of the tank liner 1 can be pressurized, and the tank liner 1 can be rotated after the tank liner 1 is pressurized, and secondary distance measurement sampling is performed on specific points of the tank liner 1 to build a secondary database of the tank liner 1. At this time, the staff can compare the distance measurement change amplitude of each point before and after pressurization. When the distance measurement change amplitude of different points in the same circumference shows an abnormal point, the machine can be stopped to test the tank liner 1, or the installation of the tank liner 1 can be adjusted.

[0033] After the pressure test of the tank liner 1, the carbon fiber winding operation can be carried out. During the carbon fiber winding process, each wireless distance sensor 7 periodically measures the distance sampling of a specific point, and judges whether the tank liner 1 is abnormally deformed according to the obtained monitoring data. The judgment method can be to manually monitor the changes of each data point for judgment, or to preset a design value, compare the monitoring data with the preset design value for judgment, or other methods can be used for judgment.

[0034] The present invention provides a core rod 6 that can rotate relative to the tank liner 1, and can use the wireless distance measuring sensor 7 on the core rod 6 to monitor multiple points on the same section of the tank. In addition, the non-contact monitoring can prevent the monitoring from affecting the carbon fiber winding, and can also prevent the carbon fiber tension during the winding process from affecting the sensor and affecting the monitoring measurement results. The wireless distance measuring sensor 7 of the core rod 6 can be reused, further reducing the processing cost.

[0035] In a preferred embodiment, for the structure of the present invention, more specifically, one end of the core rod 6 is rotatably installed on the inner side of the first rotating ring 3, and a socket 8 is provided on the inner side of the second rotating ring 5; the core rod 6 is plug-fitted into the socket 8.

[0036] As shown in the figure, the core rod 6 can be fixed on one side of the second rotating ring 5. When the tank liner 1 is fixed between the second rotating ring 5 and the first rotating ring 3, the tank liner 1 can be placed on one side of the core rod 6 first, so that the core rod 6 gradually extends into the inner side of the tank liner 1. After the first rotating ring 3 is fixed to the connecting structure, the second rotating ring 5 is fixed to the connecting structure of the tank liner 1 so that the core rod 6 and the socket 8 are plugged and matched, so that the core rod 6 can be positioned and supported at both ends, so as to maintain the position of the core rod 6 stable, so as to further ensure the coaxiality of the core rod 6 and the tank liner 1.

[0037] In a preferred embodiment, for the structure of the present invention, to be further specific, a detachable guide rod 9 is provided at one end of the core rod 6 facing the socket 8; the socket 8 is provided with a guide hole 10 for inserting the core rod 6, and the guide hole 10 is configured as a through hole so that the guide rod 9 can be pulled out from the side of the socket 8 away from the first rotating ring 3; the second rotating ring 5 includes an outer ring body 501 that can be connected to the connecting structure, and an upper seat body 502 that can be detachably connected to the outside of the outer ring body 501, and the socket 8 is arranged on the inner side of the outer ring body 501, and the upper seat body 502 can cover the guide hole 10.

[0038] like Figure 3As shown, when fixing the tank liner 1, a guide rod 9 is installed at one end of the core rod 6 facing the socket 8, and the second rotating ring 5 drives the core rod 6 and the guide rod 9 to extend into the inner side of the tank liner 1, and finally the guide rod 9 passes through the opening of the tank liner 1, and the core rod 6 is guided by the guide rod 9 to cooperate with the guide hole 10 of the socket 8, and the guide rod 9 is extended from the guide hole 10. After the core rod 6 is inserted into the guide hole 10, the guide rod 9 is taken out, and then the upper seat body 502 is connected to the outer ring body 501, and the upper seat body 502 covers the guide hole 10, thereby completing the installation and fixation of the core rod 6.

[0039] By configuring in this way, the present invention can use a guide rod 9 with a smaller diameter to facilitate passing through the guide hole 10, and guide the core rod 6 to be inserted into the guide hole 10 inside the tank liner 1 through the guide rod 9, thereby reducing the difficulty of installation and fixing. The upper seat 502 covers the guide hole 10, thereby further improving the airtightness of the inner side of the tank liner 1 after installation.

[0040] In a preferred embodiment, for the structure of the present invention, further specifically, the upper seat body 502 is provided with an air guide tube 11 connected to the guide hole 10; a rotating bearing 12 is provided in the guide hole 10, and the core rod 6 can be inserted into the rotating bearing; the rotating bearing is provided with an air hole, and / or an air gap is provided between the rotating bearing and the hole wall of the guide hole 10.

[0041] As shown in the figure, the air guide pipe 11 connected to the upper seat body 502 can be used to ventilate or release pressure inside the tank liner 1 to achieve pressurization or depressurization of the tank liner 1. By setting it in this way, no air supply pipeline is set on one side of the second rotating ring 5, thereby further reducing the difficulty of processing the position of the second rotating ring 5.

[0042] By configuring in this way, the present invention can also reduce the difficulty of modifying the existing tank liner 1 rotation support structure, and only requires to configure the core rod 6 installation component at the first rotation ring position and the socket 8 at the second rotation ring position.

[0043] The air supply pipeline arrangement of the tank liner 1 is not limited to the method of setting air holes or air gaps by rotating the bearing position and setting the air guide duct 11 through the upper seat body 502 as shown in the present invention. In an optional embodiment, other methods may also be used, such as the core rod 6 being hollowed out, and the end of the core rod 6 being rotatably extended from the second rotating ring 5 or the first rotating ring 3 and connected to the external air pipe.

[0044] Regarding the specific implementation method of the socket 8, further specific explanation is given in combination with the structure shown in the figure. In the embodiment shown in the figure, the connection structure of the tank liner 1 is configured as an interface pipe with an external thread, the outer ring body 501 of the second rotating ring 5 is threadedly connected to the outside of the interface pipe, the socket 8 is an annular structure integrally arranged on the inner side of the outer ring body 501, and the rotating bearing 12 is fixed on the inner side of the guide hole 10 of the socket 8; the upper seat body 502 is connected to the outer ring body 501 by bolts, and a rubber sealing ring is arranged between the upper seat body 502 and the outer ring body 501.

[0045] The manner in which the core rod 6 is installed in the first rotating ring is further specifically described in the illustrated embodiment. As shown in the figure, a limit plate 16 is provided at the end of the core rod 6, and the first rotating ring is provided with a guide bearing sleeved on the outside of the core rod 6 and a thrust bearing 17 arranged between the guide bearing and the limit plate 16, so as to realize the installation of the core rod 6 at the first rotating ring position.

[0046] In the illustrated embodiment, for the breathable structure at the rotating bearing, to be more specific, the rotating bearing includes a mounting ring 1201, a sliding bearing 1202 arranged on the inner side of the mounting ring 1201, and a supporting rib 1203 arranged between the mounting ring 1201 and the sliding bearing 1202.

[0047] As shown in the figure, a sliding bearing 1202 with a relatively simple structure can be used, so that the rotating bearing as a whole forms air holes between the supporting ribs 1203, which can not only improve the air permeability efficiency but also reduce the maintenance cost of the rotating bearing.

[0048] In the illustrated embodiment, for the structure of the present invention, to be more specific, the guide rod 9 is connected to the core rod 6 by interference fit.

[0049] This makes it easy to install and disassemble the guide rod 9 on the core rod 6 .

[0050] In the illustrated embodiment, for the structure of the present invention, to be more specific, the core rod 6 is provided with an identification sensor 13 at one end, and the second rotating ring 5 or the first rotating ring 3 at the position of the identification sensor 13 is provided with a plurality of marking portions 14 spaced circumferentially; the supporting device also includes a controller, and the controller is connected to the wireless ranging sensor 7 and the identification sensor 13 signal, and the controller collects the signal of the wireless ranging sensor 7 when receiving the position signal of the identification sensor 13 triggered by the marking portion 14.

[0051] In the embodiment shown in the figure, the identification sensor 13 adopts an electromagnetic proximity switch, and the marking part 14 is set to a magnetic block fixed to the second rotating ring 5, so that when the core rod 6 and the tank liner 1 rotate relative to each other, the identification sensor 13 can be triggered by the marking part 14 to determine the position information of the specific point corresponding to the data measured by the wireless ranging sensor 7, so as to facilitate the positioning of the specific point.

[0052] The present invention locates the specific mark on the tank liner 1 by identifying the sensor 13, so that the distance measurement position can be accurately controlled when the core rod 6 and the tank liner 1 rotate relative to each other, so as to further improve the monitoring accuracy.

[0053] In the illustrated embodiment, more specifically, as shown in the figure, the core rod 6 is arranged so that the center of gravity of the core rod 6 is offset from the center line of the core rod 6. By adjusting the center of gravity of the core rod 6, it is not necessary to provide a steering power input to the core rod 6. When the tank liner 1 rotates, the center of gravity of the core rod 6 is relied on to inhibit the core rod 6 from rotating with the tank liner 1, so as to promote the relative rotation of the core rod 6 and the tank liner 1.

[0054] In an optional embodiment, a driving motor may be arranged inside the first rotating ring 3 , and the core rod 6 is connected to the rotating shaft of the driving motor so that the driving motor can drive the core rod 6 to rotate relative to the tank liner 1 .

[0055] In the illustrated embodiment, to be more specific, as shown in the figure, the core rod 6 is configured as a hollow core rod 6, counterweight portions are formed at both ends of the core rod 6, and the core rod 6 is filled with a counterweight body 15 at the position of the counterweight portion, the density of the counterweight body 15 is greater than the density of the core rod 6, and the center of gravity of the counterweight body 15 is offset from the center line of the core rod 6.

[0056] In the illustrated embodiment, to be more specific, the core rod 6 is configured as a hollow core rod 6 made of aluminum alloy, and a reinforcing rib is provided inside the core rod 6, which divides the inner side of the core rod 6 into a plurality of chambers. The end of the core rod 6 is filled with a lead counterweight 15 in a chamber offset to one side of the center of the core rod 6, so that the core rod 6 can always be located at the lower side of the center line of the core rod 6 at the position of the counterweight 15 during the rotation of the tank liner 1, thereby realizing the relative rotation of the core rod 6 and the tank liner 1.

[0057] The present invention provides counterweights at both ends of the core rod 6, so that after the core rod 6 is installed inside the tank liner 1, the bending moment generated by the counterweight 15 on the middle of the core rod 6 can be reduced, so as to further prevent the core rod 6 from bending and deforming.

[0058] The present invention also provides a carbon fiber winding method for a tank liner, which is implemented based on the supporting device provided above, and the winding method includes: S1, the pressure inside the tank liner 1 is balanced with the air pressure, the tank liner 1 rotates, and the controller collects the distance signal of the wireless distance measuring sensor 7 when receiving the position signal of the identification sensor 13 triggered by the marking part 14, and constructs the initial database of the tank liner 1; The tank liner 1 may be sampled multiple times, and the average value of the distances at each specific point may be obtained to construct a primary database of the tank liner 1; S2, inflate and pressurize the inner side of the tank liner 1, rotate the tank liner 1, and when the controller receives the position signal of the identification sensor 13 triggered by the marking part 14, collect the distance signal of the wireless distance measuring sensor 7 to build a secondary database of the tank liner 1; Compare the data change range of each point in the secondary database with that of the primary database. When an abnormal point occurs in the range change range of each point corresponding to the same wireless ranging sensor 7, report the abnormality of the tank liner 1. The tank liner 1 may be sampled multiple times, and the average value of the distances at each specific point may be obtained to construct a secondary database of the tank liner 1; Whether there are abnormal points in the distance measurement change amplitude at each point corresponding to the same wireless distance measuring sensor 7, the judgment method includes: after removing the maximum and minimum values ​​of the change amplitude, averaging the remaining change amplitude values, and the change amplitude value is considered abnormal if the deviation of the average value is above a%, and a is less than or equal to 10.

[0059] S3, performing carbon fiber winding operation, the controller receives the position signal of the identification sensor 13 triggered by the marking portion 14, collects the distance signal of the wireless ranging sensor 7, and obtains three databases; Each measured data is compared with the data of the corresponding point in the three databases to determine whether the change amplitude of the current collected point data is abnormal; a specific method is to compare the average distance measurement value of a specific point in the three databases with the newly measured data, and the change value of the newly measured data is considered abnormal if it is above b%, and b is less than or equal to 10; Monitor the average value of the distance data of each specific point obtained by the same wireless distance sensor 7 to determine whether there is an abnormal problem at a specific point where the circumferential uneven deformation of the inner liner occurs; a specific method is to obtain the increase of the average value of the distance data of each specific point in the tertiary database compared with the average value of the corresponding point in the secondary database data, and the highest and lowest values ​​of each increase value corresponding to the same wireless distance sensor 7 compared with the average value of the remaining increase values ​​are considered abnormal if the change is more than c%, and b is less than or equal to 10); S4. When an abnormal point appears in S3, the newly measured data of the abnormal point is eliminated, the air pressure in the tank liner 1 is first reduced (preferably by 5%), the synchronous winding process is further monitored, and the pressure is increased again to the set value after the abnormal point is eliminated.

[0060] By reducing the pressure, the abnormal deformation stress of the abnormal position of the specific point can be released to promote the uniform deformation of the tank liner 1. During further winding, continuous monitoring can be performed within a specific winding cycle (such as 10 turns). If the abnormal position of the point can be eliminated, the winding monitoring can be performed again after the pressure is increased to the set value. If the abnormal point cannot be eliminated, the machine can be stopped for inspection.

[0061] It should be noted that the present invention improves the support device in the structure of the connection position between the first support and the second support and the tank liner, and the method for setting the core rod. There is no restriction on how the support device drives the structure of the tank liner. Those skilled in the art can flexibly select the structure of driving the tank liner in the existing tank liner support device when implementing the embodiment. In a specific embodiment, for example, the first rotating ring and the upper seat body are rotatably arranged in the bearing seat respectively and driven to rotate by a motor.

[0062] Each embodiment in this specification is described in a progressive manner, and the same or similar parts between the embodiments can be referred to each other, and 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 be referred to the partial description of the method embodiment.

[0063] The above is only an embodiment of the present application and is not intended to limit the present application.
