目前,国内外井下后卸式装岩机普遍采用滚动斗柄式工作机构,卸载时,滚动斗柄猛烈撞击横梁上的缓冲弹簧,将物料抛入矿车。合理选择横梁缓冲弹簧的位置,不仅可减少卸载时滚动斗柄与滚道间的磨损,而且能避免稳绳受力过大引起的稳绳松动和破断事故,保证装岩机安全生产。 At present, domestic and international underground rock-fill rock-fill machines commonly used rolling handle handle type working mechanism, unloading, rolling handle handle violent impact on the beam buffer spring, the material into the tub. Reasonable choice of the position of the beam buffer spring can not only reduce the wear between rolling handle and raceway during unloading, but also avoid loose and broken accident of stability rope caused by excessive force of steady rope and ensure safety production of rock loader.
