目前,在年开采量千万吨以上的大型露天矿山运输设备中,非公路自卸车已占80%~90%。作为自卸车承载部件的车斗,因其载重量大,运行环境差,致使车斗寿命缩短。针对目前车斗存在的问题,基于仿生学设计理念,采用等应力框架设计理论和车身轻量化技术,研制出具有自重轻、载重大、强度高、耐磨好、寿命长、油耗低等特点的新型车斗,实现轻量化和节能减排,提高了自卸车的市场竞争力。
At present, off-highway dump trucks account for 80% -90% of the large-scale open pit mining equipment with annual production of over 10 million tons. As a dump truck carrying parts of the car, because of its heavy load, poor operating environment, resulting in reduced bucket life. In view of the existing problems of the car body, based on the concept of bionics design and using the equal stress frame design theory and the light weight technology of the vehicle body, the invention has the advantages of light weight, heavy load, high strength, good wear resistance, long service life and low fuel consumption New car bucket, to achieve lightweight and energy saving, improve the dump truck market competitiveness.
