针对国产凿岩台车的技术水平偏低、可靠性较差,国外产品售价高、配件供应周期长的现状,开发了CHD03型凿岩台车,以PLC控制为核心,能有效地控制凿岩台车的主泵电机、空压机和水泵电机的启动和停止,具有失压、短路、过载、断相等保护措施以及具有3个钻臂工作时间的显示和故障报警功能,为隧道施工关键设备的国产化提供了有益的探索。
In view of the low technical level, poor reliability, high selling prices of foreign products and long supply cycle of the domestic drilling rigs, the CHD03 drilling rig has been developed. With the PLC control as the core, it can effectively control the chisel The rock pump main pump motor, air compressor and pump motor start and stop with loss of pressure, short circuit, overload, equal protection measures and has three working hours of the boom display and fault alarm function, the key for the construction of the tunnel The localization of equipment provides a useful exploration.
