牙轮钻机是大型露天矿的主要穿孔设备,由于该机在钻进过程中产生较大的冲击震动,致使钻头和机器零件使用寿命降低。为了解决这个问题,我院与鞍钢齐大山铁矿研制了这种新型的牙轮钻机减震器,1983年10月投入试验,效果很好,1984年又在齐矿四台牙轮钻机全部使用,工作可靠,经济效益显著。于1984年12月鞍钢公司组织通过鉴定,又于1985年8月请各有关专家复评通过冶金工业部鉴定。 DJ—1型碟簧减震器是由一组碟形薄簧呈复合式组合,承受纵向振动,由缓冲胶块承受扭转振动。而国内外已有的牙轮钻机减震器都是以橡胶作为减震元件,而把碟簧引 Tooth roller rig is the main perforation equipment for large-scale open pit mine, due to the machine in the drilling process to produce greater shock and vibration, resulting in reduced service life of drill bits and machine parts. In order to solve this problem, our institute and Anshan Iron and Steel Qidashan Iron Mine developed a new type of cone drill shock absorber, put into trial in October 1983, the effect is very good, in 1984 Qi Qi four cone drills all use , Reliable work, significant economic benefits. In December 1984 Ansteel organization passed the appraisal, again in August 1985, the relevant experts re-assessment through the Ministry of Metallurgical Industry appraisal. DJ-1-type disc spring shock absorber is composed of a group of disc-shaped thin spring was a combination of composite, to withstand the longitudinal vibration, rubber torsion vibration by the block. The existing domestic and foreign cone drill vibration damper are rubber as the damping element, and the disc spring
