Description

Technical Field

[0001] The present application relates to the technical field of bucket wheel excavators, and in particular to a wear-resistant structure of a side plate of an ore operation bucket wheel excavation bucket. Background Art

[0002] Bucket wheel excavators are a common piece of equipment used in mining operations, primarily for large-scale material excavation and transfer. One of their core components is the bucket wheel excavator's side plates. During long-term, high-intensity mining, these plates are subject to significant material impact and friction. Traditional bucket wheel excavator side plates are typically manufactured from a single material, resulting in limited wear and impact resistance. As ore hardness increases and operational intensity rises, the side plates often experience deformation and increased wear during operation. The contact areas between the side plates and the ore are particularly susceptible to damage, shortening the equipment's lifespan and increasing downtime for maintenance. Furthermore, side plate wear can cause ore to leak during excavation, resulting in wasted resources and reduced production efficiency. Conventional bucket teeth are also prone to breakage during mining operations. These teeth are typically welded to or integrally formed with the side plates, making them difficult to repair if damaged. Consequently, existing bucket wheel excavator side plate structures suffer from poor durability and a short service life, making them incapable of stable, long-term excavation operations. Utility Model Content

[0003] In order to improve the durability of the bucket wheel excavator bucket side plate and increase the service life of the bucket, the present application provides a wear-resistant structure of the bucket wheel excavator bucket side plate for ore operations.

[0004] The present application provides a wear-resistant structure for the side plate of a bucket wheel excavator for ore operation, which adopts the following technical solution:

[0005] A wear-resistant structure for the side plate of a bucket wheel excavator for ore operations includes a material baffle plate, the bottom of the material baffle plate is connected to an inclined plate, the bottom of the inclined plate is connected to a mounting plate, the material baffle plate, the inclined plate and the mounting plate are formed as one piece, a plurality of mounting seats are installed on the inner side wall of the mounting plate, the mounting seats are installed with cutting teeth, and a high-chromium composite wear-resistant lining is provided on the outer side wall of the material baffle plate.

[0006] By adopting the above technical solution, the main stress area of ​​ore impact and friction during excavation operations is extremely easy to damage. In order to extend the service life of the baffle plate, the high hardness and wear resistance of the high-chromium composite wear-resistant lining are first utilized to enable the baffle plate to cope with the wear of the ore for a long time; then, combined with the inclined design of the inclined plate, the ore slides over the inclined plate instead of directly hitting the baffle plate, thereby greatly reducing the frequency of direct contact between the baffle plate and the ore, and reducing the risk of the baffle plate being damaged due to severe friction or impact; at the same time, the pick has a strong ability to cut ore. It can not only cut ore efficiently, but also disperse the impact force of the ore to multiple cutting points, avoiding the ore from being concentrated on the baffle plate and exerting excessive force. The pick itself is strong and not easy to damage. As a bucket tooth, it is even more difficult to damage and does not need to be replaced smoothly. Because, through the synergistic effect of the pick, the baffle plate and the high-chromium composite wear-resistant lining, the durability of the bucket wheel excavator bucket side plate is improved, the service life of the bucket is increased, and the bucket can work stably for a long time.

[0007] Optionally, the outer diameter of the side of the pick facing the mounting seat is greater than the sum of the outer diameter of the mounting seat and the thickness of the mounting plate, and the edge of the side of the pick facing the mounting seat extends beyond the outer side wall of the mounting plate.

[0008] By adopting the above technical solution, the cutting teeth protrude from the outside of the mounting plate, which can reduce the wear pressure of the mounting plate in direct contact with the ore, protect the mounting plate from wear, and thus extend the service life of the entire wear-resistant structure.

[0009] Optionally, the mounting seat is welded with an arc-shaped plate, both ends of the arc-shaped plate are connected with extension plates, the extension plates are welded to the inner side wall of the mounting plate, and the mounting seat is welded to the inner side wall of the mounting plate.

[0010] The addition of curved and extended plates provides enhanced support for the mounting base, making it more stable against impact during excavation and reducing the risk of deformation or dislodging. The welded connection ensures a secure connection between the mounting base and the mounting plate, effectively enhancing the impact resistance of the bucket wheel excavator side plates and making them suitable for high-intensity ore excavation operations.

[0011] Optionally, a connecting plate is welded between adjacent mounting seats.

[0012] By adopting the above technical solution, the design of the connecting plate increases the connection strength between the mounting seats, reduces the situation where a single mounting seat is detached from the mounting plate during high-intensity operations, and thus improves the stability of the side panel structure.

[0013] Optionally, a first assembly plate is provided on the inner wall of the mounting plate, and a second assembly plate is provided on the outer wall of the mounting plate. A connecting hole is opened on the mounting plate, and a fixing bolt is passed through the second assembly plate. The fixing bolt passes through the connecting hole and the first assembly plate. The fixing bolt is threadedly connected with a fixing nut, and the fixing nut is tightened against the first assembly plate. The mounting seat and the extension plate are both welded to the first assembly plate.

[0014] By adopting the above technical solution, since the strength of the cutting teeth is always higher than the strength of the baffle plate, inclined plate and mounting plate, when the baffle plate, inclined plate or mounting plate is damaged, the first assembly plate and the second assembly plate can be removed, and all the cutting teeth can be assembled on other mounting plates at the same time, which is convenient for subsequent maintenance operations.

[0015] Optionally, a first assembly groove and a second assembly groove are formed on the mounting plate, the first assembly plate is located in the first assembly groove and the first assembly plate and the second assembly plate are located in the second assembly groove and the first assembly plate and the second assembly plate are located in the second assembly groove and the first assembly plate and the second assembly plate are located in the second assembly groove.

[0016] By adopting the above technical solution, the design of the assembly groove enables the first assembly plate and the second assembly plate to be positioned more firmly, avoiding loosening or displacement of the first assembly plate and the second assembly plate during operation, thereby enhancing the stability of the structure.

[0017] Optionally, a side of the cutting tooth facing the mounting plate is in contact with the bottom of the mounting plate.

[0018] By adopting the above technical solution, the pick fits against the bottom of the mounting plate, ensuring that the pick can be supported by the mounting plate when subjected to external force, thereby preventing the pick from falling off or being damaged due to uneven force.

[0019] Optionally, the second assembly plate and the high-chromium composite wear-resistant lining plate are both provided with wear-resistant layers on the inner and outer layers.

[0020] By adopting the above technical solutions, the wear-resistant layer design further enhances the wear resistance of the bucket wheel excavator bucket side plate and extends the service life of the high wear area.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. It is the main stress area for ore impact and friction during excavation operations, so it is extremely easy to be damaged. In order to extend the service life of the baffle plate, the high hardness and wear resistance of the high chromium composite wear-resistant liner are first utilized to enable the baffle plate to cope with the wear of the ore for a long time; then, combined with the inclined design of the inclined plate, the ore slides over the inclined plate instead of directly hitting the baffle plate, thereby greatly reducing the frequency of direct contact between the baffle plate and the ore, and reducing the risk of damage to the baffle plate due to severe friction or impact; at the same time, the pick has a strong ability to cut ore, which can not only cut ore efficiently, but also disperse the impact force of the ore to multiple cutting points, avoiding the ore from being concentrated on the baffle plate and exerting excessive force, and the pick itself is high in strength and not easy to damage, and as a bucket tooth it is even less likely to be damaged and does not need to be replaced slowly. Because, through the synergistic effect of the pick, the baffle plate and the high chromium composite wear-resistant liner, the durability of the bucket wheel excavator bucket side plate is improved, the service life of the bucket is increased, and the bucket can work stably for a long time;

[0023] 2. The pick protrudes from the outside of the mounting plate, which can reduce the wear pressure caused by direct contact between the mounting plate and the ore, protect the mounting plate from wear, and thus extend the service life of the entire wear-resistant structure;

[0024] 3. The addition of curved and extended plates provides better support for the mounting base, making it more stable when subjected to impact during excavation and reducing the risk of deformation or dislodging. The welded connection ensures a secure connection between the mounting base and the mounting plate, effectively improving the impact resistance of the bucket wheel excavator side plates and adapting to high-intensity ore excavation operations.

The inclined plate 2 is connected to the bottom of the baffle plate 1, and the mounting plate 3 is connected to the bottom of the inclined plate 2. The baffle plate 1, the inclined plate 2 and the mounting plate 3 are formed in one piece. The inclined plate 2 is inclined downward in the direction away from the outer wall of the baffle plate 1. The mounting plate 3 is arranged vertically downward, and the inner wall of the mounting plate 3 is provided with a first assembly groove 31, and the outer wall of the mounting plate 3 is provided with a second assembly groove 32. The first assembly groove 31 and the second assembly groove 32 are provided along the length direction of the mounting plate 3, and the mounting plate 3 is provided with a plurality of connecting holes 33 equidistantly along its length direction. The connecting holes 33 are connected to the first assembly groove 31 and the second assembly groove 32. A first assembly plate 41 is inserted into the first assembly groove 31, and a second assembly plate 42 is inserted into the second assembly groove 32. A plurality of fixing bolts 43 are passed through the second assembly plate 42. The fixing bolts 43 correspond to the connecting holes 33 one by one. The fixing bolts 43 pass through the corresponding connecting holes 33 and through the first assembly plate 41. The fixing bolts 43 are threadedly connected to fixing nuts 44, and the fixing nuts 44 are tightly pressed against the first assembly plate 41.

[0034] like Figure 3 and Figure 4 The first assembly plate 41 is welded with several mounting seats 5 along its length direction. The mounting seats 5 are cylindrical, and a connecting plate 51 is welded between adjacent mounting seats 5. An arc-shaped plate 52 is welded on the side of the mounting seat 5 facing away from the mounting plate 3. The arc-shaped plate 52 is in contact with the circumference of the mounting seat 5. Extension plates 53 are integrally formed at both ends of the arc-shaped plate 52, and the extension plates 53 are welded to the first assembly plate 41.

[0035] The mounting seat 5 is installed with a pick 6, and the tip of the pick 6 is set downward. The outer diameter of the side of the pick 6 facing the mounting seat 5 is greater than the sum of the outer diameter of the mounting seat 5 and the thickness of the mounting plate 3. The edge of the pick 6 facing the mounting seat 5 extends over the outer wall of the mounting plate 3, and the side of the pick 6 facing the mounting plate 3 is in contact with the bottom of the mounting plate 3.

[0036] like Figure 2 and Figure 5 A high chromium composite wear-resistant lining plate 7 is welded on the outer wall of the baffle plate 1, and a wear-resistant layer 8 is provided on the inner and outer layers of the second assembly plate 42 and the high chromium composite wear-resistant lining plate 7;

[0037] The wear-resistant layer 8 can be a high-chromium cast iron or chromium carbide material integrally cast with the second assembly plate 42 and the high-chromium composite wear-resistant liner 7;

[0038] The wear-resistant layer 8 may also be a chromium carbide or nickel-based alloy material that is welded onto the second assembly plate 42 and the high-chromium composite wear-resistant liner 7;

[0039] The wear-resistant layer 8 can also be a tungsten carbide material thermally sprayed on the second assembly plate 42 and the high chromium composite wear-resistant lining plate 7 , or a wear-resistant ceramic sheet bonded to the second assembly plate 42 and the high chromium composite wear-resistant lining plate 7 .

[0040] The implementation principle of the embodiment of the present application is as follows: during the excavation operation, it is the main stress area of ​​ore impact and friction, so it is extremely easy to be damaged. In order to extend the service life of the baffle plate 1, the high hardness and wear resistance of the high chromium composite wear-resistant lining 7 are first utilized to enable the baffle plate 1 to cope with the wear of the ore for a long time; then, with the inclined design of the inclined plate 2, the ore slides over the inclined plate 2 instead of directly hitting the baffle plate 1, thereby greatly reducing the frequency of direct contact between the baffle plate 1 and the ore, and reducing the risk of damage to the baffle plate 1 due to severe friction or impact; at the same time, the pick 6 has a strong ability to cut ore, which can not only cut ore efficiently, but also disperse the impact force of the ore to multiple cutting points, avoiding the ore from being concentrated on the baffle plate 1 and exerting excessive force, and the pick 6 itself is high in strength and not easy to damage, and as a bucket tooth, it is even more difficult to damage and does not need to be replaced smoothly. Because, through the synergistic effect of the pick 6, the baffle plate 1 and the high chromium composite wear-resistant lining 7, the durability of the bucket wheel excavator bucket side plate is improved, the service life of the bucket is improved, and the bucket can work stably for a long time.

[0041] It should be noted that, in other embodiments, in order to facilitate production and manufacturing, the mounting base 5 and the extension plate 53 may be directly welded to the mounting plate 3, which is more suitable for scenarios where the mining intensity requirement is not high.

[0042] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
