Description

Technical Field

[0001] The utility model relates to the technical field of mining machinery accessories, and more specifically to a mining lining plate. Background Art

[0002] Mining Lining Plate is a specially designed wear-resistant plate, whose core function is to protect the inner wall of mining machinery and equipment from direct wear by ore or other materials. These equipment play a vital role in ore mining and processing, so the use of lining plates can significantly improve the durability and production efficiency of equipment.

[0003] Mining linings are usually installed in key equipment such as conveyors, crushers, ball mills, chutes, etc. In these equipment, ore or other materials come into contact with the inner wall of the equipment under high-speed movement or high pressure, resulting in severe wear of the inner wall. Mining linings are formed by covering the inner wall to form a protective layer, effectively reducing the direct contact between the material and the inner wall of the equipment, thereby reducing the degree of wear.

[0004] Most of the linings used on the market are of integrated structure, which is very inconvenient for later maintenance and repair. In addition, during the installation of general modular linings, the alignment operation between adjacent linings is very inconvenient, which consumes a lot of time and manpower costs.

[0005] For this purpose, we designed a mining liner. Utility Model Content

[0006] Technical issues to be solved

[0007] The purpose of the utility model is to provide a mining lining plate to solve the problems raised in the above background technology.

[0008] A mining lining comprises a base plate, one end of which is fixedly mounted with a first T-shaped insert, the other end of which is provided with a first slot for inserting the first insert of another base plate, the size of the first slot being matched with the first insert, a plurality of second inserts being plugged into the base plate, a plurality of second slots being matched with the plurality of second inserts being provided on the base plate, and a plurality of bosses being fixedly mounted on the second insert.

[0009] Preferably, the bottom plate is a layered structure, comprising a sound absorbing layer, a reinforcing layer and a plate body, the plate body is made of polyurethane, and a plurality of mounting holes for installation are provided on the bottom plate.

[0010] Preferably, the convex column is a layered structure, comprising a column body, a buffer layer and a wear-resistant layer, and the column body is made of polyurethane.

[0011] Preferably, the sound absorbing layer is made of mineral wool.

[0012] Preferably, the reinforcement layer is made of high manganese steel.

[0013] Preferably, the buffer layer is made of rubber.

[0014] Preferably, the wear-resistant layer is made of alumina ceramic material.

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] 1. The arrangement of the first insert and the second slot makes it easier to align two adjacent liner plates. At the same time, the arrangement of fixing the boss on the second insert makes it easier to replace the boss, which is more convenient for later maintenance and repair operations.

[0017] 2. The bottom plate and the convex column of the lining plate of the utility model have simple structure, strong practicality and wide application prospects;

[0018] 3. The sound-absorbing layer of the bottom plate can reduce the noise caused by impact during use to a certain extent. The reinforcement layer of the bottom plate and the wear-resistant layer of the convex column improve the wear resistance of the device and extend the service life of the lining.

[0027] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-Figure 6 The mining lining comprises a bottom plate 1, a first T-shaped inserting strip 11 is fixedly mounted on one end of the bottom plate 1, a first slot 12 for inserting the first inserting strip 11 of another bottom plate 1 is provided at the other end of the bottom plate 1, the size of the first slot 12 is adapted to the first inserting strip 11, a plurality of second inserting strips 2 are plugged into the bottom plate 1, a plurality of second slots 13 adapted to the plurality of second inserting strips 2 are provided on the bottom plate 1, and a plurality of bosses 21 are fixedly mounted on the second inserting strips 2.

[0029] That is to say, the two lining boards can be butt-jointed by inserting the first inserting strip 11 of one lining board into the first slot 12 of another lining board.

[0030] Furthermore, the base plate 1 is a layered structure, which includes a sound-absorbing layer 14, a reinforcing layer 15 and a plate body 16, the plate body 16 is made of polyurethane, and a plurality of mounting holes 17 for installation are provided on the base plate 1, the boss 21 is a layered structure, the boss 21 includes a column 211, a buffer layer 212 and a wear-resistant layer 213, and the column 211 is made of polyurethane.

[0031] In a further embodiment, the sound absorbing layer 14 is made of mineral wool, the reinforcing layer 15 is made of high manganese steel, the buffer layer 212 is made of rubber, and the wear-resistant layer 213 is made of alumina ceramic.

[0032] In a further embodiment, the sound absorbing layer 14 is made of rock wool, the reinforcing layer 15 is made of chrome-molybdenum steel, the buffer layer 212 is made of glass fiber, and the wear-resistant layer 213 is made of alloy.

[0033] It should be noted that, during use, since the liner is usually installed on the inner wall of a conveyor, crusher, ball mill, etc., the force levels of the bosses 21 at different positions are different. After a period of use, the second plug strips 2 at positions with a greater force level can be swapped with the second plug strips 2 at positions with a relatively smaller force level. This operation saves more time and labor costs than replacing the liner. When the boss 21 on a second plug strip 2 needs to be replaced, the second plug strip 2 can be directly replaced. When the bosses 21 on most of the second plug strips 2 on the liner need to be replaced, the liner can be directly replaced.

[0034] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
