—1型气动鑿岩支架(即气腿子)是一种新型的气动自动推进式鑽架(圖1)。它具有輕便減輕体力劳动,改进劳动組織和提高鑿岩效率等优点,为使用手持式風鑽(OM—506)打眼时最为适用的一种鑽架。在我局几个队的試行工作中,亦已充分地証明了它的优越性。使用它不但可以減少立架、折架、換钎、和松紧螺絲等工序,減少鑿岩过程中的輔助时間;而且还可降低鑿岩成本。如104队自从採用气腿子鑿岩以来,其工班效率比原气支架提高61.7％;成本降低5.1％。
- Type 1 pneumatic rock drill support (air leg) is a new type of pneumatic self-propelled drill rig (Figure 1). It has the advantages of light and easy physical labor, improved labor organization and improved rock drilling efficiency. It is a drilling rig most suitable for drilling with a hand-held pneumatic drill (OM-506). In the trial work of several teams in our Bureau, it has also fully demonstrated its superiority. Using it not only can reduce the process of erecting, folding, changing the brazing, and loosening screws, and can reduce the auxiliary time in the rock drilling process; it can also reduce the cost of rock drilling. For example, since the 104th team used gas leg drilling, the efficiency of its work class has increased by 61.7% compared with the original gas support; the cost has decreased by 5.1%.
