H175型凿岩台车已被广泛地用于水利、铁道建设行业,但是,由于其上的进口配件较昂贵,所以很多单位在维修时都不敢更换过多的配件,因而达不到修复的要求,影响了机器的使用性能。我们从节约的角度出发,对一些配件进行自行加工,不仅恢复了机器性能,更降低了生产成本。现将加工凿岩机钎尾导向轴承和推进梁滑轮的一些方法作一介绍,以作交流。 H175 drilling rigs have been widely used in the water conservancy and railway construction industries. However, due to the high cost of imported spare parts, many units did not dare to change too many spare parts during repair and could not reach the repair Requirements, affecting the performance of the machine. We save from the point of view, some of the accessories for self-processing, not only restored the machine performance, but also reduce production costs. At present, we will introduce some methods for machining the drill guide shaft and the propulsion pulley of the rock drill to make an exchange.
