To improve the anchorboltholes drilling process in the tunnel rigidsuspensioncatenary installation and construction, a new type of tunnel drilling device was developed.In the device,hydraulic system was used to drive its mechanic motion. According to its function requirements, the device’s hydraulic control system was designed. According to the needs of the sequence control of relays and electromagnets, the device’s circuit control system was designed. A wireless remote control system which was composed by wirelessremotecontroldevelopmentboard and walkietalkie was designed to control the signal of the device’s control system which made the drilling device more convenient and intelligent. Through electrohydraulic system parameters reasonable match and design, a tunnel drilling device with strong stability and relatively high degree of automation was developed.
