Description

Technical Field

[0001] The utility model relates to the technical field of wear-resistant steel plates, and specifically relates to a wear-resistant steel plate with an impact-resistant composite structure. Background Technique

[0002] In industrial applications, wear-resistant steel plates are widely used in fields such as mines, construction, and transportation to resist high wear and impact loads. Although traditional steel plates have good wear resistance, when facing impact loads, they often lack an effective impact-resistant structure, resulting in insufficient performance and affecting service life and safety.

[0003] In order to improve the impact resistance of steel plates, existing technologies usually adopt the method of increasing the thickness of the steel plates. This method can improve the impact resistance to a certain extent, but it also brings a series of problems:

[0004] 1. Weight increase: As the thickness of the steel plate increases, its weight will also increase significantly, which not only increases the difficulty of transportation and installation but also is not conducive to the requirements of lightweight application scenarios;

[0005] 2. Stress concentration: When a thick steel plate is impacted, due to the change in its thickness, stress concentration may occur, thereby reducing the overall impact resistance.

[0006] Therefore, it is necessary to develop a new wear-resistant steel plate with an impact-resistant composite structure to improve its impact resistance without increasing the thickness of the steel plate while maintaining the characteristics of lightweight. Content of the Utility Model

[0007] The purpose of the utility model is to provide a wear-resistant steel plate with an impact-resistant composite structure to solve the problem that the change in thickness mentioned in the above background technique may cause stress concentration, thereby reducing the overall impact resistance.

[0008] To achieve the above purpose, the utility model provides the following technical solution: A wear-resistant steel plate with an impact-resistant composite structure includes a steel plate body. The steel plate body sequentially includes a base layer, an impact-resistant layer, and a wear-resistant layer from bottom to top. It is characterized in that card slots are provided in the impact-resistant layer and the wear-resistant layer, and an impact-resistant energy-absorbing mechanism is provided in the card slots. The impact-resistant energy-absorbing mechanism can be a honeycomb plate. The honeycomb plate is clamped with the card slot and is located on the upper surface of the base layer. The honeycomb plate is provided with annularly distributed energy-absorbing holes.

[0009] As a preferred technical solution of the content of the utility model, the impact-resistant energy-absorbing mechanism further includes corrugated columns. The corrugated columns can be of a solid structure and are in contact with the inner wall of the card slot. The corrugated columns are located above the honeycomb plate.

[0010] As a preferred technical solution of the content of the present utility model, a through hole is further provided at the central position of the corrugated column, and a reinforcing rib is further included, and the reinforcing rib is clamped with the inner wall of the through hole.

[0011] As a preferred technical solution of the content of the present utility model, a hexagonal prism is further included, and the hexagonal prism is inserted inside the reinforcing rib and abuts against the inner wall of the through hole.

[0012] As a preferred technical solution of the content of the present utility model, the outer edge of the corrugated column has a circular structure, and the inner edge of the corrugated column has a hexagonal structure.

[0013] As a preferred technical solution of the content of the present utility model, the length of the corrugated column is greater than the length of the hexagonal prism, and the length of the hexagonal prism is the same as the length of the reinforcing rib.

[0014] Compared with the prior art, the beneficial effect of the wear-resistant steel plate with an impact-resistant composite structure of the present utility model is:

[0015] By designing a composite structure of corrugated columns and hexagonal prisms in the wear-resistant steel plate, a lightweight design is realized, the weight of the steel plate is reduced, which is convenient for transportation and installation. The composite structure of corrugated columns and hexagonal prisms can provide good energy absorption capacity when being impacted, disperse and absorb the impact energy, effectively improving the impact resistance performance of the steel plate. By arranging reinforcing ribs between the corrugated columns and the hexagonal prisms, the stress distribution inside the steel plate is improved, the phenomenon of stress concentration is reduced, and the stability of the overall structure is improved.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4 , the present utility model provides a technical solution: a wear-resistant steel plate with an impact-resistant composite structure, including a steel plate body 1. The steel plate body 1 successively includes a base layer 4, an impact-resistant layer 3, and a wear-resistant layer 2 from bottom to top. It is characterized in that card slots 10 are provided in the impact-resistant layer 3 and the wear-resistant layer 2, and an impact-resistant energy absorption mechanism is provided in the card slots 10. The impact-resistant energy absorption mechanism can be a honeycomb plate 7. The honeycomb plate 7 is clamped with the card slot 10 and is located on the upper surface of the base layer 4. Energy absorption holes 9 are annularly distributed on the honeycomb plate 7.

[0023] The impact-resistant energy absorption mechanism further includes corrugated columns 5. The corrugated columns 5 can be of solid structure and are in contact with the inner wall of the card slot 10. The corrugated columns 5 are located above the honeycomb plate 7. The length of the corrugated columns 5 is relatively long, and the part that extends beyond the length of the hexagonal prism 6 itself is connected to the wear-resistant layer 2. When the steel plate is impacted, the corrugated columns 5 absorb and disperse the impact energy as the initial energy absorption.

[0024] A through hole 11 is further provided at the central position of the corrugated column 5. There is also a reinforcing rib 8. The reinforcing rib 8 is clamped with the inner wall of the through hole 11. The shape and structure of the corrugated column 5 can increase its own surface area, can produce plastic deformation when impacted, absorb the impact energy, and reduce the damage to the main body.

[0025] A through hole 11 is further provided at the central position of the corrugated column 5. There is also a reinforcing rib 8. The reinforcing rib 8 is clamped with the inner wall of the through hole 11. The honeycomb plate 7, the corrugated column 5, and the hexagonal prism 6 are made of the same material as the base layer 4. The honeycomb plate 7 cooperates with the energy absorption holes 9 distributed inside. When impacted, the honeycomb units collapse and undergo plastic deformation, absorbing and dispersing the impact energy to avoid stress concentration and affecting the impact resistance performance.

[0026] The outer edge of the corrugated column 5 is in a circular shape structure, and the inner edge of the corrugated column 5 is in a hexagonal structure. The length of the corrugated column 5 is greater than the length of the hexagonal prism 6. The length of the hexagonal prism 6 is the same as the length of the reinforcing rib 8. And the impact-resistant layer 3 is distributed in a five-point rectangular intersection line, which can not only reduce the consumption of materials and reduce the weight of the steel plate itself, but also avoid uneven heat treatment of the steel plate during processing due to excessive thickness of the steel plate, thus ensuring the performance of the overall structure.

[0027] Working principle: The corrugated column 5 and the card slot 10 can be connected by welding. There is a length difference between the corrugated column 5 and the hexagonal prism 6. The extended part of the hexagonal prism 6 serves as a preliminary contact part, enabling the impact-resistant layer 3 to have a dual impact-resistant structure. The hexagonal prism 6, as the shorter part, not only has its own lateral impact resistance but also can ensure the stability of the material layer as the base point of the corrugated column 5. When the steel plate is impacted, the shape structure of the corrugated column 5 can increase its own surface area, generate plastic deformation when impacted, absorb the impact energy, and reduce the damage to the main body. Moreover, the honeycomb unit composed of the honeycomb plate 7 and the energy-absorbing holes 9 collapses and undergoes plastic deformation when the steel plate is impacted, absorbing and dispersing the impact energy to avoid stress concentration and affecting the impact resistance performance.

[0028] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
