[0028] The utility model discloses make further detailed instructions below with the drawings.

[0029] Combining the drawings Figure 1 to the drawings Figure 4 A wear-resistant flange assembly, comprising:

[0030] Base 1 is circular ring base 1, and a through hole is arranged in the middle;

[0031] The circular table connecting block 2 is welded on the upper surface of the base 1, a plurality of reinforcing ribs 3 are arranged on the circumference of the circular table connecting block 2, and a through hole is arranged in the circular table connecting block 2;

[0032] The upper seat 4 is welded on the upper surface of the circular table connecting block 2, and a through hole is arranged in the upper seat 4;

[0033] The lower surface of the base 1 and the upper surface of the upper seat 4 are both provided with shock-absorbing soft pads 5.

[0034] The surfaces of the base 1, the circular table connecting block 2 and the upper seat 4 are all coated with wear-resistant layers, and the wear-resistant layers are three-layer structures of a bottom layer 6, a middle layer 7 and an upper layer 8.

[0035] The edges of the base 1 are all provided with round corners. The edges of the base 1 are provided with round corners, which can effectively avoid scratching the operators in the process of assembly and use, improve the operation safety, and reduce the stress concentration points, reduce the risk of cracks and damage of the edges of the base 1 under stress, prolong the service life of the base 1 and enhance the structural stability of the entire flange assembly

[0036] The reinforcing ribs are arranged at equal intervals. The circular table connecting block 2 is more evenly stressed. When the flange assembly bears a load, the reinforcing ribs 3 at equal intervals can evenly disperse and transmit the force, avoiding deformation of the circular table connecting block 2 caused by excessive local stress.

[0037] The edges of the upper seat 4 are all provided with round corners. Similar to the round corner design of the edges of the base 1, the round corner design of the edges of the upper seat 4 can prevent injuries to personnel during installation and maintenance. Moreover, the round corner can relieve the stress generated when the edges of the upper seat 4 contact and rub against other components, reducing the possibility of wear and damage.

[0038] The bottom layer 6 is a zinc-chromium coating layer. It has excellent corrosion resistance. It can form a dense protective film on the surface of the base 1, the round table connecting block 2 and the upper seat 4, effectively preventing the contact of external moisture, oxygen and corrosive medium with the base metal, and preventing the rusting and corrosion of the metal. The middle layer 7 is a ceramic coating layer. It can withstand greater friction and wear, and effectively resist the damage of various friction factors to the bottom layer 6 and the base metal during the working process of the flange assembly, thereby greatly improving the wear resistance of the flange assembly. The upper layer 8 is a fluorocarbon coating layer. It has a very low friction coefficient, which can significantly reduce the friction force between the flange assembly and other parts during relative motion, reduce energy loss and improve the operation efficiency of the equipment. In addition, the fluorocarbon coating layer also has good weather resistance, chemical corrosion resistance and self-cleaning performance.

[0039] Working principle: In actual work, the wear-resistant flange assembly plays an important role in connection and buffering. First, from the aspect of connection, various connecting parts, such as bolts and pins not shown in the drawing, pass through the entire assembly through the same diameter circular holes of the base 1, the round table connecting block 2 and the upper seat 4. Since the hole diameters are uniform, the concentricity of the installation of the connecting parts is ensured, so that the connection is stable and reliable, and the force can be uniformly transmitted during work, reducing local stress abnormalities.

[0040] When the equipment is running, the shock-absorbing soft pads 5 under the base 1 and above the upper seat 4 play a role. The shock-absorbing soft pads 5 effectively absorb the vibration energy, reduce the influence of vibration on the entire equipment and the connected parts, and improve the stability of the equipment operation.

[0041] And in terms of wear resistance and protection, the three-layer wear-resistant layer on the surface works together. The zinc-chromium coating layer of the bottom layer 6 forms a dense protective film to block the contact of external corrosive medium with the base metal and prevent rusting and corrosion, which can be seen in the drawing covering the surface of each part. The ceramic coating layer of the middle layer 7 resists friction and wear during work by virtue of high hardness, protecting the bottom layer and the base. The fluorocarbon coating layer of the upper layer 8 has a very low friction coefficient, which reduces the friction force when moving relative to other parts, reduces energy loss, and at the same time, its good weather resistance, chemical corrosion resistance and self-cleaning performance keep the surface of the assembly clean and prolong the service life. The entire flange assembly works together to ensure the stable and efficient operation of the equipment.

[0042] In the description of the present application, it should be pointed out that, unless otherwise explicitly specified and limited, the term "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected, and those skilled in the art can understand the specific meaning of the above-mentioned term in the present application according to the specific circumstances.

[0043] The above has described the utility model and its implementation mode, which is not restrictive, and the drawings only show one of the implementation modes of the utility model, and the actual structure is not limited thereto. In summary, if a person skilled in the art is inspired thereby, without departing from the creative purpose of the utility model, similar structural modes and embodiments are not creatively designed, which should belong to the protection scope of the utility model.
