非开挖钻机智能化控制研究

Research on intelligent control of trenchless drilling rig

摘要:

为提高我国非开挖装备的智能化水平，将钻机液压系统由传动功能提升至智能控制功能，实现科学钻进，研发了一款智能化多功能定向钻进系统。该系统还针对施工中容易出现的马达“超速”、“超压”、“吸空”现象，对马达进行了保护，通过对泵排量的补偿缓解了系统压力冲击，并能根据负载智能匹配发动机功率，防止发动机熄火。

Abstract:

In order to increase the intelligent level of trenchless equipment in our country, and upgrade the hydraulic system of drilling rig from the transmission function to the intelligent control function to achieve proper drilling, an intelligent multi-functional directional drilling system has been developed. The system also protects the motor from the “overspeed”, “overpressure” and “ air-vacuum” phenomena that are prone to occur during drilling, relieves the pressure impact of the system through the compensation of the pump displacement, and intelligently matches the engine power according to the load to prevent the engine from stalling.
