Description

Technical Field

[0001] The present invention belongs to the technical field of wear-resistant plates, and more specifically, particularly relates to a spliced ​​wear-resistant composite plate. Background Art

[0002] Metal wear-resistant composite plate is composed of low-carbon steel plate and wear-resistant layer. The wear-resistant layer generally accounts for 1 / 3 to 1 / 2 of the total thickness. The surface hardness of the wear-resistant layer can reach HRc60 or above. Secondary hardening will occur within a certain temperature range, further improving the wear resistance. It has the characteristics of high hardness and high toughness composite materials, good impact resistance, and the wear-resistant layer will not fall off during use. It can also be cut, bent, welded and other processes. Under large-area wear conditions, the wear-resistant composite plate will have more severe local wear than the whole or other areas. As a result, the severely worn local area will be abandoned or replaced as a whole when it cannot work, which wastes the wear-resistant layer in other parts and reduces the economic cost performance. Summary of the invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: a spliced ​​wear-resistant composite plate, including a substrate layer, characterized in that: a reinforcing layer and a protective wear-resistant layer are respectively provided on both sides of the substrate layer, a reinforcing plate is provided on the outside of the reinforcing layer, a cavity is provided inside the reinforcing layer, a plurality of reinforcing columns are provided in the cavity, a stabilizing structure is provided on the top of the reinforcing column, a threaded interface ring is also provided on the surface of the stabilizing structure, and a threaded connection column is also provided on the side of the reinforcing plate close to the stabilizing structure for fixed connection; the inside of the protective wear-resistant layer is a hollow body, and the outside of the protective wear-resistant layer is provided with a wear-resistant area.

[0005] Preferably, the stabilizing structure comprises a shock-absorbing ring located on the surface of the reinforcing column, and a layer of shock-absorbing spring is sleeved on the outside of the shock-absorbing ring.

[0006] Preferably, the reinforcement columns are connected by reinforcement ribs.

[0008] Preferably, the substrate layer, the reinforcement layer and the protective wear-resistant layer are made of steel or copper.

[0010] The present invention provides a spliced ​​wear-resistant composite plate, which has the following beneficial effects: 1. The three-layer structure design of protective wear-resistant layer, base layer and reinforcement layer is adopted to improve the overall strength of PC endurance board; by setting reinforcement plates and reinforcement columns in the reinforcement layer, the tolerance of the board can be improved, and the stable structure can greatly reduce the damage to the internal structure of the wear-resistant board caused by external impact.

[0011] 2. The spliced ​​wear-resistant composite plate has the advantage of efficient replacement. The parts that are not severely worn can be reused, and only the severely worn parts need to be replaced, thereby improving the utilization rate of materials. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0018] In the description of the present invention, unless otherwise specified, "plurality" means two or more than two; the orientations or positional relationships indicated by the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", etc. are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0019] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] See also Figures 1 to 4 The present invention provides a technical solution: a spliced ​​wear-resistant composite plate, comprising a substrate layer 1, a reinforcing layer 2 and a protective wear-resistant layer 3 are respectively arranged on both sides of the substrate layer 1, a reinforcing plate 4 is arranged outside the reinforcing layer 2, a cavity is arranged inside the reinforcing layer 2, a plurality of reinforcing columns 5 are arranged in the cavity, a stabilizing structure 6 is arranged on the top of the reinforcing column 5, a threaded interface ring 7 is also sleeved on the surface of the stabilizing structure 6, and a threaded connection column 8 is also arranged on the side of the reinforcing plate 4 close to the stabilizing structure 6 for fixed connection; the protective wear-resistant layer 3 is hollow inside, and a wear-resistant area 9 is arranged outside the protective wear-resistant layer 3. The stabilizing structure 6 includes a shock-absorbing ring 61 located on the surface of the reinforcing column 5, and a layer of shock-absorbing spring 62 is also sleeved on the outside of the shock-absorbing ring 61. The reinforcing columns 5 are connected by reinforcing ribs 10. A pouring port 11 is arranged on the surface of the wear-resistant area 9.

[0021] The substrate layer 1, the reinforcement layer 2 and the protective wear-resistant layer 3 are made of steel and copper. The substrate layer 1, the reinforcement layer 2 and the protective wear-resistant layer 3 have the same thickness.

[0022] The specific usage and function of this embodiment: by setting the reinforcing layer 2 on one side of the substrate layer 1, the overall strength of the wear-resistant plate is improved. By relying on the reinforcing plate 4 on the surface of the reinforcing layer 2, it can resist external impact and protect the structure of the inner plate layer. The hollow body on one side of the reinforcing plate 4 is provided with reinforcing columns 5 connected to each other by reinforcing ribs 10. While ensuring the stability of its own structure, it protects and supports the stability of the structure inside the cavity, thereby improving the overall impact resistance. In addition, the reinforcing column 5 is also stably connected to the reinforcing plate 4 on one side, relying on the shockproof plates on both sides of the stable structure 6 and the spring and shock-absorbing ring 61 at the center, which can greatly reduce the damage caused by external impact to the internal structure of the endurance plate. The connection is stable and the force is uniform, which plays a good role in protecting the internal layer structure. A wear-resistant protective layer is also provided inside the substrate layer 1. The wear-resistant area 9 on the inner surface of the wear-resistant protective layer is added with a wear-resistant coating to improve the wear resistance and service life of the finishing.
