The safe and efficient production of mining is now a key work that has received wide attention from all walks of life. Among them, side dumping mine car are more typical mechanical equipment used in mining production. Mine car provide support for many mining safety production. Regarding the structural design of coal mining car The editor briefly summarizes the lightweight design in.
As a lifting container, the side dumping mine car has a certain structural size, and the smaller its own weight, the better. One of the ways to reduce its own weight is to use high-strength and light-weight materials.
(1) Use high-strength aluminum alloys, such as LY12-CZ, LC4-CZ, LC15 (formerly 157), etc. used in China.
(2) The use of low-alloy steel can reduce its own weight by about 20%; for example, the United States adopts cooling casting technology to change the hydrogen content in alloy steel, and the lifting container made of it can increase the life of up to 10 years; the Federal Republic of Germany and the United Kingdom use Compared with Q235 steel, the high-strength alloy plate produced by the nano-precipitation technology is used to manufacture coal transportation equipment. The service life is increased by 50% and the dead weight is reduced by 22.5-40%.
(3) The use of duplex steel is a kind of high-alloy stainless steel, which belongs to austenitic-ferritic steel with high strength and good corrosion resistance. Using this to replace low-alloy steel 16Mn, the weight of the skip can be reduced by 1/3. Zhou Nairong and others used DP1 dual-phase steel as the material of the car box and frame to design a light mine car for coal mines. Part of the structure was improved, the dead weight was reduced by 30%, the service life was extended by more than 50%, and the wagon coefficient was reduced from 0.6 to 0.42. The center of gravity of the entire carriage is low, and the running stability is good.
The above three kinds of steel exist in order to realize the lightweight of the mine car, and hope to help more customers understand the mine truck in depth, and provide support and help to enrich the daily production needs.
