Description

Technical Field

[0001] This utility model relates to the field of liner technology, specifically to an improved wear-resistant liner. Background Technology

[0002] Liners are used to protect the mill body from direct impact and friction between the grinding media and materials. Different types of liners can also be used to adjust the movement of the grinding media to enhance the crushing effect of the grinding media on the materials, thereby improving the grinding efficiency of the mill, increasing output, and reducing metal consumption.

[0003] Currently, lining plates frequently come into contact with and rub against materials during use. The surface of the lining plates is mostly made of two materials: metal or rubber. Metal materials are not wear-resistant, while rubber materials have problems such as not being firmly fixed, being easy to detach, and having deformed edges and corners during use. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide an improved wear-resistant liner to solve the problems of poor wear resistance and poor stability of the liner mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an improved wear-resistant liner, comprising a load-bearing base plate, a limiting metal plate detachably connected to one side of the load-bearing base plate, a protective metal sleeve fixedly connected to one side of the limiting metal plate, a wear-resistant surface layer provided on the inner side of the protective metal sleeve, the limiting metal plate and the protective metal sleeve being detachably connected, a rough surface provided on the inner side of the protective metal sleeve, and the rough surface being fused to the outer wall of the wear-resistant surface layer.

[0006] Preferably, the upper and lower ends of the limiting metal plate are connected with connecting bolts, and one end of the connecting bolt is threadedly connected to the protective metal sleeve.

[0007] Preferably, the inner side of the load-bearing base plate is provided with a groove, and the groove corresponds to the position of the connecting bolt.

[0008] Preferably, a connecting rod is fixedly connected to the other side of the limiting metal plate, and the connecting rod is symmetrically distributed about the bisector of the limiting metal plate.

[0009] Preferably, one end of the connecting rod is rotatably connected to a rotating shaft, and a limit rod is fixedly connected to the outer wall of the rotating shaft.

[0010] Preferably, the load-bearing base plate has a through hole, the position of which corresponds to the position of the connecting rod, and one end of the connecting rod is inserted into the through hole of the load-bearing base plate.

[0011] Preferably, a connecting frame is fixedly connected to the inner wall of the through hole of the load-bearing base plate. The connecting frame has a limiting hole. The shape of the limiting hole is the same as the shape of the combination of the limiting rod and the rotating shaft. The length and width of the limiting rod are both smaller than the length and width of the corresponding position of the limiting hole.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] (1) By using a combination of metal and rubber materials, this device not only avoids severe deformation around the wear-resistant surface layer, but also improves the overall wear resistance and service life, and reduces maintenance costs.

[0014] (2) This device solves the problem of easy deformation of the edges and corners of the wear-resistant surface layer by wrapping a protective metal sleeve around the outer wall of the wear-resistant surface layer made of rubber. At the same time, the wear-resistant surface layer also has good wear resistance. Meanwhile, by setting a load-bearing base plate and a limiting metal plate on one side of the wear-resistant surface layer, the support of the wear-resistant surface layer is ensured and the stability of the wear-resistant surface layer is improved.

[0015] (3) This device connects the limiting metal plate and the protective metal sleeve with connecting bolts, which ensures the stability of the wear-resistant surface layer installation and also facilitates disassembly. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides a technical solution: an improved wear-resistant liner, including a load-bearing base plate 1, a limiting metal plate 2 detachably connected to one side of the load-bearing base plate 1, and a groove on the inner side of the load-bearing base plate 1, the groove corresponding to the position of the connecting bolt 4; this structure can reserve space for the end of the connecting bolt 4, avoiding the phenomenon that the load-bearing base plate 1 cannot completely fit the surface of the limiting metal plate 2; a through hole is provided on the load-bearing base plate 1, the position of the through hole corresponding to the position of the connecting rod 7, one end of the connecting rod 7 being inserted into the through hole of the load-bearing base plate 1; a connecting frame 10 is fixedly connected to the inner wall of the through hole of the load-bearing base plate 1, and a limiting hole 11 is provided on the connecting frame 10, the shape of the limiting hole 11 being the same as the shape of the combination of the limiting rod 8 and the rotating shaft 9, the length and width of the limiting rod 8 being smaller than the length and width of the corresponding position of the limiting hole 11; this structure is as shown in the appendix to the specification. Figure 5 As shown, when the limiting rod 8 is in a longitudinal state, it is away from the limiting hole 11. At this time, the limiting metal plate 2 is stably connected to the load-bearing base plate 1. When the limiting rod 8 is in a rightward transverse state, it is located at the limiting hole 11. At this time, pulling the limiting metal plate 2 can separate it from the load-bearing base plate 1. This structure can realize the quick installation and separation of the load-bearing base plate 1 and the limiting metal plate 2, which is convenient for workers to maintain and replace the limiting metal plate 2 or the components on the limiting metal plate 2. The upper and lower ends of the limiting metal plate 2 are connected with connecting bolts 4, and one end of the connecting bolt 4 is threadedly connected to the protective metal sleeve 3. This structure can ensure the stability of the limiting metal plate 2 and the protective metal sleeve 3. The other side of the limiting metal plate 2 is fixedly connected with a connecting rod 7, which is parallel to the limiting metal plate 2. The dividing lines are symmetrically distributed vertically. This structure, by setting a limiting metal plate 2, can support and limit the wear-resistant surface layer 6, improving the stability of the wear-resistant surface layer 6 during installation and use. One end of the connecting rod 7 is rotatably connected to a rotating shaft 9, and a limiting rod 8 is fixedly connected to the outer wall of the rotating shaft 9. This structure allows the limiting rod 8 to be rotated to adjust its angle. A protective metal sleeve 3 is fixedly connected to one side of the limiting metal plate 2, and the wear-resistant surface layer 6 is provided inside the protective metal sleeve 3. The limiting metal plate 2 and the protective metal sleeve 3 are detachably connected. A rough surface 5 is provided inside the protective metal sleeve 3, and the rough surface 5 is fused to the outer wall of the wear-resistant surface layer 6. By setting the rough surface 5, this device can make more sufficient and firm contact with the wear-resistant surface layer 6, thereby ensuring the stability of the wear-resistant surface layer 6 during use.

[0024] Working principle: When using this improved wear-resistant liner, if it is necessary to replace the limiting metal plate 2 or the components on the limiting metal plate 2, the rotating shaft 9 can be rotated so that the limiting rod 8 is in a horizontal state and located at the limiting hole 11. Then, the limiting metal plate 2 is pulled, so that the connecting rod 7, the limiting rod 8 and the rotating shaft 9 on the outer wall of the limiting metal plate 2 can be separated from the connecting frame 10 inside the load-bearing base plate 1. Then, the connecting bolt 4 that fixes the limiting metal plate 2 and the protective metal sleeve 3 can be removed. Then, the limiting metal plate 2 is separated from the protective metal sleeve 3. Finally, the wear-resistant surface layer 6 can be cut and separated and replaced.

[0025] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
