我分队广大职工在施工实践中因陋就简,不断改进脚踏打眼机,使手工凿岩效率提高10～20%,减轻了劳动强度。打眼机结构简单,经久耐用,使用安全。几年来,利用它已完成二百多米的手掘坑道。在山区工作分散、交通不便、流动性大的施工中尤为适用。脚踏打眼机(图1)是由木质轱辘、中轴、固定中轴的厚铁板、铁锤、踏板、机架和安全托钎架等部分构成。固定中轴的厚铁板(图2)上面有3个圆孔,打顶眼时将中轴套进最高的孔内,打
The vast majority of our employees in the construction practice because of the simple, continuous improvement of eyebolt machine, the manual drilling efficiency increased by 10 to 20%, reducing labor intensity. Eyebolt machine structure is simple, durable, safe to use. In recent years, it has completed more than 200 meters of hand-dug tunnels. In the mountains scattered work, traffic inconvenience, mobility is particularly applicable to the construction of large. Pedal drilling machine (Figure 1) is a wooden wheel, the axis, the fixed axis of the thick iron plate, hammer, pedal, rack and safety brackets and other components. Thick iron plate fixed axis (Figure 2) There are three round holes above, hit the top of the eye when the sleeve into the highest hole, hit
