[0033] The preferred embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0034] like Figures 1 to 10 As shown, this embodiment provides a frame box for sea transportation of large aircraft components, including: a base frame structure 1, a column assembly structure 2 and a connecting rod structure 3, wherein the column assembly structure 2 is rotatably arranged at both ends of the base frame structure 1, and the connecting rod structure 3 is obliquely arranged between the base frame structure 1 and the column assembly structure 2, one end of the connecting rod structure 3 is connected to the base frame structure 1, and the other end of the connecting rod structure 3 is connected to the column assembly structure 2.

[0035] like Figure 1 , Figure 2 , Fig. 9 and Fig.10 As shown, the column assembly structure 2 of this embodiment is rotatably arranged at both ends of the chassis structure 1, and is opened when it is needed to be shipped by sea, and the strength and rigidity of the structure are improved through the connecting rod structure 3, so as to ensure the structural stability and reliability of the frame box, and ensure that the frame box is still stable and reliable in a multi-layer stacking structure. Figures 3 to 5 As shown, when there is no sea transportation, the column assembly structure 2 can be laid flat to reduce the occupied volume, improve the humanized design of the product, and improve the return transportation efficiency.

[0036] It should be noted that the connecting rod structure 3 of this embodiment is provided with a first sensor, which includes but is not limited to a stress sensor and / or an angle sensor. The stress sensor is used to monitor the force of the connecting rod structure 3 to ensure the strength of the connecting rod structure 3 is effective, thereby ensuring the structural stability of the overall frame; the angle sensor can be used to monitor the column angle to ensure the stress state of the column assembly structure 2 and enhance the ability of the column assembly structure 2 to resist buckling when it is overloaded.

[0037] like Figure 1 and Figure 6 As shown, the connecting rod structure 3 of this embodiment includes a rod seat 301, a connector 302 and a connector 303. One end of the connector 303 is connected to the column assembly structure 2 through the connector 302 and the rod seat 301, and the other end of the connector 303 is connected to the base frame structure 1 through the connector 302. At this time, a rod seat is also preferably provided in the base frame structure 1 to facilitate rapid and stable assembly with the connector 302. The connector 303 is also called an intermediate connector and is used as the main structure of the connecting rod structure 3.

[0038] Preferably, the connecting rod structure 3 of this embodiment also includes an adjusting member 304 and an adjusting locking member 305. The connecting member 303 is connected to the adjusting member 304 through the adjusting locking member 305. The adjusting member 304 can adopt a screw structure, and the adjusting locking member 305 can adopt a locking nut, etc. Through the arrangement of the adjusting member 304 and the adjusting locking member 305, the length adjustment function of the connecting rod assembly can be realized. The locking member 305 ensures that the length of the connecting rod assembly does not change due to bumps and vibrations during sea transportation, thereby avoiding changes in the relative angle between the frame box column assembly structure 2 and the base frame structure 1, which causes changes in the bearing capacity of the frame box, so as to meet the actual application requirements of the frame box.

[0039] like Figure 1 and Figure 7As shown, the base frame structure 1 in this embodiment includes a steel plate box 101, a hinge plate assembly 102 and an end plate assembly 103, the end plate assembly 103 is arranged at both ends of the steel plate box 101, the hinge plate assembly 102 is arranged on both end sides of the steel plate box 101, and the column assembly structure 2 is connected to the base frame structure 1 through the hinge plate assembly 102 and the end plate assembly 103.

[0040] The bottom of the chassis structure 1 of this embodiment adopts a steel plate box body 101, which can bear the weight of large aircraft components, and is preferably equipped with sensors such as stress sensors to monitor the stress state during transportation in real time; the chassis structure 1 is convenient for setting multiple lashing and fixing points, and the positions and numbers of the lashing and fixing points can be set and adjusted according to actual conditions to provide sufficient fixing points for the lashing of large aircraft components. Stress sensors are set on the fixing points to monitor the lashing force, ensure that large aircraft components do not shift during transportation, and do not cause the lashing system to fail due to overload of a single lashing piece, and also avoid damage to large aircraft components. The setting of the hinge plate assembly 102 and the end plate assembly 103 facilitates the connection and support of the column assembly structure 2 above its two ends, and ensures the effectiveness of the structure, and can also meet the requirements of saving stowage space when the frame box is returned.

[0041] like Figure 1 and Figure 7 As shown, the chassis structure 1 of this embodiment also preferably includes a rotary lock assembly 104 and a tool box assembly 105. The rotary lock assembly 104 is arranged in the steel plate box 101. The rotary lock assembly 104 refers to a structure that rotates to achieve locking, including a cargo delivery rotary lock plate and a rotary positioning ring, etc., which is convenient for locking through a rotary locking structure; the tool box assembly 105 is arranged at both ends of the steel plate box 101, which is convenient for more reasonable and full use of the existing space. The rotary lock assembly 104 refers to a fixed position reserved for loading other goods. Figure 1 and Figure 8 As shown, the column assembly structure 2 described in this embodiment includes a column component 201, a pivot connecting plate 202, an inclined beam 203, an inclined beam reinforcement plate 204 and a top beam component 205. The column component 201 is connected to the hinge plate component 102 and the end plate component 103 of the base structure 1 through the pivot connecting plate 202. The inclined beam 203 is cross-arranged between the column components 201 on both sides, and the inclined beam reinforcement plate 204 is arranged at the cross position of the inclined beam 203 to ensure the reliability of the column structure. The top beam component 205 is arranged on the top of the column component 201 to achieve support connection and fixing with the frame box of the upper layer.

[0042] Preferably, the present embodiment further comprises a heat-resistant anti-corrosion protective layer, which is arranged on the outer surface of the chassis structure 1, the column assembly structure 2 and the connecting rod structure 3. The heat-resistant anti-corrosion protective layer refers to a heat-resistant anti-corrosion paint layer of silicone-modified epoxy resin, also known as heat-resistant anti-corrosion paint; the heat-resistant anti-corrosion protective layer has both heat-resistant and anti-corrosion properties. It cures at room temperature and can be used at 150°C for a long time; it can reach 180~200°C for a short time. It has the effects of resistance to moisture, water, oil and salt spray erosion, and is very suitable for use in shipping environments, which is beneficial to improving the corrosion resistance of the frame box.

[0043] It is worth noting that the chassis structure 1 and the column assembly structure 2 described in this embodiment are both provided with a second sensor, and the second sensor includes any one or more of a stress sensor, an acceleration sensor, an angle sensor, a height sensor, a temperature sensor and a humidity sensor.

[0044] In this embodiment, sensors are provided on the chassis structure 1, the column assembly structure 2 and the connecting rod structure 3 for monitoring the cargo position, stress state, angle data, height data, temperature and humidity data, and real-time acceleration data, etc. The data are collected through a data acquisition module and uploaded to a monitoring center or a cloud platform system, etc., and compared with respective preset thresholds. When the preset thresholds are exceeded, an alarm signal is issued, so that the sea transportation process of large aircraft parts is safer and more reliable, and the visualization, controllability and information traceability of the entire sea transportation process are greatly improved.

[0045] like Fig. 9 and Fig.10 As shown, the frame box of this embodiment adopts a multi-layer stacking structure, and the number of layers and the number of parallel arrangements of the multi-layer stacking structure can be adjusted according to actual conditions. The chassis structure 1 of the upper frame box is arranged on the column assembly structure 2 of the lower frame box. The column assembly structure 2 of the lower frame box can support the chassis structure 1 of the upper frame box, increase the utilization rate of the stowage space, and can also effectively protect the goods in the frame box, thereby more effectively improving the transportation capacity under the condition of limited voyages and cabin space.

[0046] In summary, in the frame box used for the sea transportation of large aircraft parts, the connecting rod structure 3 described in this embodiment is tilted between the base frame structure 1 and the column assembly structure 2, one end of the connecting rod structure 3 is connected to the base frame structure 1, and the other end of the connecting rod structure 3 is connected to the column assembly structure 2, thereby ensuring the structural stability and reliability of the frame box. On this basis, the actual sensor data can also be monitored by sensors, and each structure can be optimized to provide a better hardware foundation for improving the intelligent design and humanized design of the product, ensuring the stability of the multi-layer stacking structure, ensuring the strength and load-bearing capacity of the structure, and improving the corrosion resistance of the frame box, so as to better meet the sea transportation needs of large aircraft parts.
