Description

Technical Field

[0001] This utility model belongs to the field of lining plates, specifically, it relates to a high-strength wear-resistant lining plate with a novel structure. Background Technology

[0002] In modern industrial production, many industries such as metallurgy, power, mining, building materials, and cement often subject equipment to harsh working conditions requiring high wear resistance, high strength, and impact resistance. As a key component in these equipment, liners play a crucial role, and their performance directly affects the operating efficiency and service life of the equipment. Liners are functional components installed on the internal surface of industrial equipment, mainly serving to protect, resist wear, prevent corrosion, and reduce vibration, much like putting a "protective armor" on the equipment. However, existing liners are generally made of cast iron in one piece, which has the defects of poor wear resistance, weak strength, and short service life.

[0003] Chinese patent CN212579343U discloses a metal composite wear-resistant liner. This device is made by welding a liner body to a high-strength circular ring. The liner body is made of a composite of a metal compound layer, a hypereutectic high-chromium alloy wear-resistant layer, a high-chromium cast iron layer containing a modified composite agent, and a soft steel substrate. The high-strength circular ring is made of the same material as the liner body. The metal composite wear-resistant liner with the above structure has the advantages of strong wear resistance, high strength, and long service life. However, the liner of this device needs to be replaced entirely after wear, and it cannot be replaced according to the wear location, resulting in high cost and cumbersome overall replacement.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a high-strength wear-resistant liner with a novel structure, thus solving the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A novel high-strength wear-resistant liner includes: a liner body with multiple mounting grooves recessed at its top;

[0008] A wear-resistant block is detachably installed in the mounting groove. A plug is fixedly installed on the wear-resistant block. The mounting groove is provided with a slot for the plug to be inserted. A fourth positioning hole is provided opposite the end of the wear-resistant block to the plug. A first positioning hole is provided opposite the fourth positioning hole of the liner body. A first positioning bolt is provided in the first positioning hole and threadedly connected to the fourth positioning hole.

[0009] Optionally, multiple biomimetic wear-resistant grooves are fixedly installed on the top of the wear-resistant block.

[0010] Optionally, both the first positioning hole and the slot are provided in two sets.

[0011] Optionally, a rubber pad is fixedly installed on the inner wall of the mounting groove.

[0012] Optionally, it also includes at least two embedded plates, which are fixedly installed on the side of the liner body. The liner body has an embedded groove that allows the embedded plate to be embedded. A third positioning hole is provided through the embedded plate. A second positioning hole is provided through the liner body relative to the positioning hole. A second positioning bolt is provided on the liner body that can pass through the second positioning hole and the third positioning hole.

[0013] Optionally, both the second positioning hole and the third positioning hole are multiple.

[0014] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art. Of course, any product implementing this utility model does not necessarily need to achieve all of the following advantages at the same time:

[0015] 1. By setting up inserts, slots, and wear-resistant blocks, the inserts and slots provide pre-positioning through cooperation, and the bolts ensure connection strength, improving maintenance efficiency. The wear-resistant blocks evenly transfer the load through the bolts, reducing the direct stress on the liner body and extending the liner's life. After wear, only the wear-resistant blocks need to be replaced, without the need for complete scrapping, thus reducing maintenance costs.

[0016] 2. By incorporating biomimetic wear-resistant textures, the frictional resistance between the material and the liner surface is reduced, thus decreasing abrasive wear. The wear-resistant textures guide material flow, preventing concentrated wear caused by localized accumulation. The grooves can accommodate a small amount of abrasive debris, reducing secondary wear.

[0017] 3. By incorporating rubber pads, the impact energy of materials is absorbed, reducing liner vibration and noise.

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] Please see Figure 1-6 As shown, this embodiment provides a novel high-strength wear-resistant liner, including a liner body 1 with multiple mounting grooves 11 recessed at its top, a wear-resistant block 2 detachably mounted in the mounting grooves 11, a mounting insert 14 fixedly mounted on the wear-resistant block 2, a slot 12 for inserting the insert 14 in the mounting groove 11, a fourth positioning hole 15 opposite to the end of the wear-resistant block 2 away from the insert 14, a first positioning hole 4 opposite to the fourth positioning hole 15 in the liner body 1, and a first positioning bolt 5 threadedly connected to the fourth positioning hole 15 in the first positioning hole 4.

[0031] Specifically, the insert 14 of the wear-resistant block 2 is aligned with the slot 12 in the mounting groove 11 of the liner body 1, inserted and positioned, and the first positioning bolt 5 is screwed in through the first positioning hole 4 and the fourth positioning hole 15 to achieve threaded fastening. Similarly, during disassembly, the first positioning bolt 5 is removed, the wear-resistant block 2 is taken out from the mounting groove 11, and a new wear-resistant block 2 is replaced. The overall structure and operation steps are simple. After wear, only a part of the wear-resistant block 2 needs to be replaced, without the need for complete scrapping, which reduces maintenance costs. The cooperation between the insert 14 and the slot 12 provides pre-positioning, and the bolt fastening ensures connection strength and improves maintenance efficiency. The wear-resistant block 2 transmits the load evenly through the bolt, reducing the direct force on the liner body 1 and extending the liner life.

[0032] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, multiple biomimetic wear-resistant patterns 3 are fixedly installed on the top of the wear-resistant block 2. Specifically, the biomimetic wear-resistant patterns 3 can imitate biological structures such as shark skin and pangolin scales to reduce the frictional resistance between the material and the liner surface, reduce abrasive wear, guide the material flow, avoid concentrated wear caused by local accumulation, and the texture grooves can accommodate a small amount of abrasive debris to reduce secondary wear.

[0033] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the first positioning hole 4 and the slot 12 are provided in two sets. A rubber pad 13 is fixedly installed on the inner wall of the mounting slot 11. Specifically, the rubber pad 13 absorbs the impact energy of the material and reduces the vibration and noise of the liner.

[0034] In this embodiment, as Figures 1 to 6 As shown, it also includes at least two embedded plates 8, which are fixedly installed on the side of the liner body 1. The liner body 1 has an embedded groove 10 that allows the embedded plates 8 to be embedded. The embedded plate 8 is provided with a third positioning hole 9. The liner body 1 is provided with a second positioning hole 6 that is provided with the positioning hole. The liner body 1 is provided with a second positioning bolt 7 that can pass through the second positioning hole 6 and the third positioning hole 9. There are multiple second positioning holes 6 and third positioning holes 9.

[0035] Working principle:

[0036] When replacing the wear-resistant block 2, according to the required installation depth of the wear-resistant block 2, align the insert 14 of the wear-resistant block 2 with the slot 12 in the mounting groove 11 of the liner body 1 and insert it for initial positioning. Align the first positioning hole 4 with the fourth positioning hole 15, screw in the first positioning bolt 5, and fix the wear-resistant block 2 in the mounting groove 11 to achieve the installation of the wear-resistant block 2. When installing two liner bodies 1, insert the embedding plate 8 of one liner body 1 into the embedding groove 10 on the side of the other liner body 1. Adjust the position of the embedding plate 8 to the embedding groove 10 according to the actual situation so that the second positioning hole 6 is aligned with the third positioning hole 9. Insert the second positioning bolt 7 and tighten it with the nut to achieve the installation between the two liner bodies 1.
