[0015] The following is a further detailed description of the specific embodiments of the present invention. It should be understood that the description of the present invention herein is not intended to limit the protection scope of the present invention.

[0016] like Figure 1 to Figure 2 As shown, it is a schematic diagram of the structure of a wear-resistant plate that is beneficial to improving the service life provided by the utility model. The wear-resistant plate that is beneficial to improving the service life includes a base plate 10, a wear-resistant layer 20 disposed on the base plate 10 and fixedly connected to the base plate 10, and a lubrication unit 30 disposed on the wear-resistant layer. It is conceivable that the wear-resistant plate that is beneficial to improving the service life should also include some other functional components, such as mounting components, etc., which are well known to those skilled in the art and will not be described one by one here.

[0017] The substrate 10 can be a square structure, which is the main load-bearing part of the wear-resistant plate that is beneficial to improving the service life. The substrate 10 is mainly composed of fiber and resin, that is, the substrate 10 at least includes a first fiber layer 11, and a resin layer 12 coated on the outside of the first fiber layer. Fiber has the advantages of high flexibility, thermal stability, plasticity and high strength, while resin has good heat resistance, plasticity, chemical stability, corrosion resistance, and good mechanical properties such as hardness, strength, toughness, etc. Therefore, the fiber layer 11 and the resin layer 12 are combined to form the substrate 10, so that the substrate 10 is lighter, more resistant to fatigue and more resistant to corrosion than the traditional metal substrate, while meeting the strength and hardness of the substrate 10.

[0018] The wear-resistant layer 20 includes a wear-resistant layer body 21 and a plurality of mounting grooves 22 disposed on the wear-resistant layer 21 .

[0019] The wear-resistant layer body 21 is arranged corresponding to the substrate 10, that is, the length and width of the wear-resistant layer body 21 are consistent with the substrate 10, and are also square structures. The wear-resistant body 21 is mainly made of PTFE and high-strength fiber fabric impregnated with epoxy resin and made through a specific process. PTFE is the abbreviation of polytetrafluoroethylene, commonly known as "plastic king" or Teflon, and is a polymer material with many excellent properties.

[0020] The wear-resistant layer body 21 includes at least one polytetrafluoroethylene layer 211, at least one second fiber layer 212 arranged on one side of the polytetrafluoroethylene layer 211, and an epoxy resin layer 213 coated on the polytetrafluoroethylene layer 211 and the outer side 212 of the second fiber layer. The polytetrafluoroethylene layer 211 is mainly made of polytetrafluoroethylene material. Polytetrafluoroethylene has excellent characteristics such as high heat resistance, corrosion resistance, and chemical stability, so that PTFE is undoubtedly the best choice as a wear-resistant material. The second fiber layer 212 is mainly composed of high-strength fibers. The use of high-strength fibers makes the wear-resistant body 21 more resilient and less prone to breakage. The epoxy resin layer 213 is formed by immersing the polytetrafluoroethylene layer 211 and the second fiber layer 212 in epoxy resin. The polytetrafluoroethylene layer 211 and the second fiber layer 212 are fixedly connected by epoxy grease, and the epoxy grease layer 213 is formed outside the polytetrafluoroethylene layer 211 and the second fiber layer 212 to further protect the polytetrafluoroethylene layer 211 and the second fiber layer 212. Preferably, the thickness of the wear-resistant layer body 21 is less than the thickness of the substrate 10, which can be determined according to the actual use environment.

[0021] The mounting groove 22 is arranged on the side of the wear-resistant layer body 21 opposite to the substrate 10, so as to accommodate and install the lubrication unit 30. The mounting groove 22 can be a plurality of circular grooves provided on the wear-resistant layer body 21. It can be understood that the mounting groove 22 is mainly used to accommodate the lubrication unit 30, so its shape is not limited, and it can also be a square, diamond or other easy-to-process shape. A plurality of the mounting grooves 22 are symmetrically arranged along the length direction of the wear-resistant layer body 21, and the mounting grooves 22 are arranged in a diamond shape, and the diagonal lines of the diamond shape coincide with the midlines of the length and width of the wear-resistant layer body 21, respectively. The number and size of the mounting grooves 22 can be specifically set according to the size of the wear-resistant layer body 21 and the use environment.

[0022] The base plate 10 and the wear-resistant layer 20 can flexibly adjust the material ratios according to the use environment, so that the wear-resistant plate can meet the use requirements of different environments.

[0023] The lubrication unit 30 includes a plurality of lubrication columns respectively inserted into the mounting grooves 22. The lubrication unit 30 is a column made of a material having a lubricating effect corresponding to the structural shape of the mounting groove 22, such as graphite. Graphite has good self-lubricating properties and can reduce friction and wear in oil-free mining, thereby extending the service life of the equipment. The number of lubrication columns of the lubrication unit 30 is equal to the number of the mounting grooves 22.

[0024] Compared with the prior art, the utility model provides a wear-resistant plate that is conducive to improving the service life, which includes a substrate 10, a wear-resistant layer 20 arranged on the substrate 10 and fixedly connected to the substrate 10, and a lubricating unit 30 arranged on the wear-resistant layer 20. The substrate 10 includes at least one first fiber layer 11 and a resin layer 12 coated on the outside of the first fiber layer 11. The wear-resistant layer 20 includes a wear-resistant layer body 21 and a plurality of mounting grooves 22 arranged on the side of the wear-resistant layer body 21 facing away from the substrate. The wear-resistant layer body 21 includes at least one polytetrafluoroethylene layer 211, at least one second fiber layer 212 arranged on one side of the polytetrafluoroethylene layer 211, and an epoxy resin layer 213 coated on the polytetrafluoroethylene layer 211 and the outside 212 of the second fiber layer. The use of the fiber layer 11 and the resin layer 12 enables the substrate 10 to have good hardness, toughness, chemical stability and corrosion resistance, and the ratio of fiber and resin can be changed according to the use environment so that the substrate 10 meets the use requirements. The polytetrafluoroethylene layer 211, the second fiber layer 212, and the epoxy layer 213 respectively improve the heat resistance, friction resistance, toughness, strength and other dimensions of the wear-resistant layer body 21. At the same time, the lubrication unit 30 is also arranged on the wear-resistant layer 20 to further reduce the adverse effect of friction force on the wear-resistant layer 20 during the friction process, thereby greatly improving the service life of the wear-resistant plate.
