Description

Technical Field

[0001] This utility model belongs to the field of honeycomb casting technology, specifically relating to a reinforced honeycomb casting structure. Background Technology

[0002] Honeycomb casting structures are frequently used in ships due to their lightweight, high strength, and high rigidity. They can reduce the weight of the hull while ensuring the strength of the hull structure, thereby improving the ship's speed and fuel economy. Since ships are affected by wave impacts and hull vibrations during navigation, honeycomb casting structures used in the superstructure shell and bulkheads of ships need to have higher strength and impact resistance to ensure structural safety. However, ordinary honeycomb casting structures have a large unsupported area in the middle region, which makes them unable to provide good impact resistance when facing wave impacts and hull vibrations during navigation, resulting in reduced structural safety. Utility Model Content

[0003] This invention proposes a reinforced honeycomb casting structure that provides support for the internal area of ​​the honeycomb casting, helps improve the impact resistance of the internal area, buffers and absorbs the impact at the connection between two honeycomb castings, disperses the load, alleviates stress concentration, and further enhances the overall impact resistance of the honeycomb casting.

[0004] To achieve the above objectives, a reinforced honeycomb casting structure is provided, comprising: a honeycomb casting, wherein a plurality of impact-resistant inner components are installed on the inner side of the honeycomb casting, and the other ends of the plurality of impact-resistant inner components are interconnected; the impact-resistant inner components include hollow connecting rods and a plurality of stacked honeycomb buffer components; and a plurality of elastic buffer components are embedded on the outer side of the honeycomb casting, wherein the elastic buffer components include elastic components and two mounting seats, and the two mounting seats are respectively fixedly connected to the two ends of the elastic components.

[0009] This utility model has the following beneficial effects:

[0010] 1. Under the action of the impact-resistant internal components, the internal area of ​​the honeycomb casting can be supported. At the same time, the combination of elastic deformation and plastic deformation of the honeycomb buffer can help improve the impact resistance of the internal area of ​​the honeycomb casting.

[0011] 2. Under the action of the elastic buffer, the impact at the connection between the two honeycomb castings is buffered and consumed through elastic deformation and plastic deformation.

[0018] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0019] Example 1:

[0020] like Figure 1As shown in Figure 5: A reinforced honeycomb casting structure includes a honeycomb casting 1. Several impact-resistant inner components 2 are installed on the inner side of the honeycomb casting 1, and the other ends of the several impact-resistant inner components 2 are connected to each other. The impact-resistant inner component 2 includes a hollow connecting rod 21 and several stacked honeycomb buffer components 22. The honeycomb buffer component 22 is located inside the hollow connecting rod 21, and the honeycomb buffer component 22 includes three honeycomb plates 221 connected end to end. The outer edge of the honeycomb buffer component 22 is fixedly connected to the inner cavity of the hollow connecting rod 21. A reinforcing connecting seat 11 is fixedly connected at the corner of the inner side of the honeycomb casting 1, and one end of the hollow connecting rod 21 is fixedly connected to the reinforcing connecting seat 11.

[0021] In this implementation plan:

[0022] As the basic framework of the entire honeycomb structure, several impact-resistant internal components 2 located in the honeycomb casting 1 form a support for the inner cavity area of ​​the honeycomb casting 1. Simultaneously, an impact-resistant surface is formed within the inner cavity area of ​​the honeycomb casting 1, and the internal space of the honeycomb casting 1 is divided by several impact-resistant internal components 2, resulting in several stable triangular structures within the inner cavity of the honeycomb casting 1. The number of impact-resistant internal components 2 is consistent with the number of sides of the honeycomb casting 1. When six impact-resistant internal components 2 are placed in the inner cavity of the hexagonal honeycomb casting 1 to support the inner cavity, these six impact-resistant internal components 2 can form a "distributed layout" within the inner cavity area of ​​the honeycomb casting 1. When the inner cavity of the honeycomb casting 1... When an area is subjected to external impact, the impact load can be transferred from the stress concentration area to the interior in multiple directions. For example, when the external impact causes a longitudinal collision along the axial direction of the impact-resistant inner component 2, the load can be transferred to the honeycomb buffer 22 through the hollow connecting rod 21, and then diffused to the surrounding area by the honeycomb buffer 22, avoiding local stress concentration. When the external impact causes a transverse impact on the impact-resistant inner component 2, such as a lateral collision or vibration, the impact-resistant inner component 2 can disperse the load to other support rods or the casting body through the bending of the shell of the hollow connecting rod 21 and the shear deformation of the honeycomb buffer 22, reducing the peak load of a single area. It can effectively disperse the external impact force and avoid the external impact causing a concentrated impact on a certain area.

[0023] When the impact-resistant inner component 2 is subjected to external impact, since each honeycomb buffer 22 is composed of three honeycomb frames, the honeycomb plate 221 can buffer the load through elastic deformation, such as frame bending and torsion, when the impact load is applied. If the load exceeds the elastic limit, it can also continuously dissipate energy through plastic deformation. When the honeycomb buffer 22 is made of metal, it can continuously dissipate energy through the yielding of the metal frame. When the honeycomb buffer 22 is made of composite material, it can continuously dissipate energy through the delamination of the composite material frame.

[0024] The impact-resistant inner component 2 is composed of a honeycomb buffer 22 inside the hollow connecting rod 21. Compared with using solid rods directly, this helps to reduce the overall weight of the casting. When an impact occurs, the hollow connecting rod 21 can constrain the deformation direction of the honeycomb buffer 22. During an impact, the hollow connecting rod 21 can first disperse the load by bending or stretching itself, and then transfer it to the honeycomb buffer 22 for further energy absorption. At the same time, the deformation of the honeycomb buffer 22 reacts to the outer shell, which can prevent excessive local deformation of the outer shell. When the impact-resistant inner component 2 is subjected to a small impact, the elastic deformation of the hollow connecting rod 21 and the honeycomb buffer 22 can buffer the load and protect the casting body. When the impact-resistant inner component 2 is subjected to a large impact, the plastic deformation depth of the honeycomb buffer 22 consumes energy, prolongs the load action time, and prevents the casting body from failing due to instantaneous high load. The reinforcing connecting seat 11 is used to reinforce the connection between the end of the impact-resistant inner component 2 and the inner corner of the honeycomb casting 1.

[0025] Example 2:

[0026] like Figure 1 As shown in Figure 5: An elastic buffer is embedded on the outer side of the honeycomb casting 1. The elastic buffer includes an elastic element 3 and two mounting seats 31, and the two mounting seats 31 are respectively fixedly connected to the two ends of the elastic element 3. An installation chamber 12 is opened on the outer side of the honeycomb casting 1. A connecting groove 121 is opened on both sides of the installation chamber 12. The elastic element 3 is located inside the installation chamber 12. The mounting seats 31 are slidably connected to the inside of the connecting groove 121. The depth of the installation chamber 12 is half the height of the elastic element 3.

[0027] In this implementation plan:

[0028] The mounting compartment 12, located outside the honeycomb casting 1, provides space for the elastic element 3, while the connecting groove 121 provides space for the mounting base 31. The mounting base 31 is installed between the connecting groove 121 and the damping slide rail. The length of the connecting groove 121 is greater than or equal to the axial elongation of the elastic element when it undergoes maximum deformation, and the width of the connecting groove 121 is greater than or equal to the radial expansion of the elastic element when it undergoes maximum deformation. When assembling several honeycomb castings 1, they can be connected and fixed by fasteners such as screws. When connecting several honeycomb castings 1, damping slide rails are installed on the connecting grooves 121 of both honeycomb castings 1, and the mounting base 31 is installed through the damping slide rails. The mounting base 31 is placed inside the mounting compartment 12. The mounting base 31 is slidably connected to the inner compartment of the connecting groove 121, which can avoid deformation interference caused by the elastic deformation of the elastic element 3. In addition, since ships mainly experience medium and high frequency vibrations, the elastic element 3 can be made of high fatigue toughness materials, such as spring steel.

[0029] When an external impact is applied to the connection of a honeycomb casting formed by several honeycomb castings 1, the elastic element 3 first buffers the external force through elastic deformation. If the impact energy is too large, the elastic element 3 enters the plastic deformation stage and consumes the energy of the external force. It also consumes energy through irreversible deformation, preventing the load from continuing to be transmitted at the connection. At this time, the entire elastic buffer forms a two-stage energy absorption of "elastic-plastic", which can effectively weaken the impact load.

[0030] The elastic element 3 is snapped into the chamber formed by two adjacent installation chambers 12, which can form a "cross-unit" force transmission path. When the edge of a single honeycomb casting 1 is impacted, the load acting on the edge of the single honeycomb casting 1 can be "diverted" to the adjacent honeycomb casting 1 through the elastic element 3, avoiding the load being concentrated on a single honeycomb casting 1, which helps to help disperse the load. When the impact load is transmitted along the surface of the honeycomb casting 1, the deformation of the elastic element 3 can disrupt the load transmission direction, such as dispersing the in-plane impact to the out-of-plane, weakening the superposition effect of the "stress wave" at the connection. At this time, the "cross-honeycomb snap-fit" method of the elastic buffer can achieve load dispersion, alleviate stress concentration, and help to further improve the impact resistance of the entire honeycomb casting.

[0031] The working principle of this technical solution is as follows: First, when assembling several honeycomb castings 1, the honeycomb castings 1 can be connected and fixed with screws. When connecting several honeycomb castings 1, damping slide rails are installed on the connecting grooves 121 of two honeycomb castings 1, and the damping slide rails are installed with the mounting base 31. The mounting base 31 is placed inside the mounting compartment 12. During use, when the ship is impacted, the impact-resistant inner component 2 can buffer and disperse the load in the internal area of ​​the honeycomb casting 1, and the elastic component 3 can buffer and disperse the load at the connection between the two honeycomb castings 1. At the same time, the impact-resistant inner component 2 can provide support for the honeycomb casting 1 inside the honeycomb casting 1, so that the entire honeycomb casting maintains good impact resistance during use.
