Benefits of technology

[0018]本发明的锚杆机打退钻控制系统，在锚杆机作业时，分别扳动手动液控比例多路阀中的第一液控阀组和第二液控阀组，以使第一液控阀组向打钻马达输送工作油以驱使打钻马达正转并向自动打退钻控制阀组输送控制油，同时第二液控阀组向工作油缸的无杆腔输送工作油以驱使工作油缸工进并通过工作油缸的无杆腔油路向自动打退钻控制阀组输送控制油，且控制油路自动打退钻控制阀组输送控制油，自动打退钻控制阀组即将控制油分别输送至第一液控阀组的液控口和第二液控阀组的工进液控口，此时，打钻马达正转与工作油缸工进同步动作，以维持自动打钻状态，实现自动打钻功能；当自动打钻到极限位置时触发行程阀，行程阀连通打钻马达和自动打退钻控制阀组，以使打钻马达向自动打退钻控制阀组输送控制油，自动打退钻控制阀组即将控制油分别输送至第一液控阀组的液控口和第二液控阀组的工退液控口，此时，第一液控阀组的工作位不变，第二液控阀组切换工作位，以向工作油缸的有杆腔输送工作油以驱使工作油缸工退并通过工作油缸的有杆腔向自动打退钻控制阀组输送控制油，打钻马达正转与工作油缸工退同步动作，以激活并维持自动退钻状态，实现自动打钻完成后即自动退钻的功能；当自动退钻到极限位置时，第二液控阀组通过工作油缸的无杆腔油路向自动打退钻控制阀组输送大于设定压力的控制油，自动打退钻控制阀组即将控制油输送至油箱，第一液控阀组和第二液控阀组复位至初始工作位，打钻马达和工作油缸停止动作，以激活并维持停钻状态，实现自动退钻完成后即自动停钻的功能；本方案通过手动液控比例多路阀、自动打退钻控制阀组、打钻马达、行程阀和工作油缸，在人工扳动手动液控比例多路阀以启动锚杆机后，即可控制锚杆机自动打钻、自动打钻完成后自动退钻以及自动退钻完成后自动停钻，即锚杆机启动后全程无需人工关注，即可实现自动打退钻作业，相对于现有技术，自动化程度高，工作人员劳动强度低，锚杆机作业效率高，实用性强，适于广泛推广和应用。

Abstract

The application discloses an anchor rod machine drill pulling control system and an anchor digging complete equipment, and belongs to the field of anchor rod machine drilling technology. The anchor rod machine drill pulling control system comprises a manual hydraulic control proportional multi-way valve, an automatic drill pulling control valve group, a drilling motor, a stroke valve and a working oil cylinder. The manual hydraulic control proportional multi-way valve comprises a control oil way, a first hydraulic control valve group and a second hydraulic control valve group. The stroke valve is connected with the drilling motor and the automatic drill pulling control valve group respectively. The automatic drill pulling control valve group is used for conveying control oil to the hydraulic control port of the first hydraulic control valve group and the working hydraulic control port of the second hydraulic control valve group to maintain an automatic drilling state, or conveying control oil to the hydraulic control port of the first hydraulic control valve group and the working hydraulic control port of the second hydraulic control valve group to activate and maintain an automatic drill pulling state, or conveying control oil to an oil tank to activate and maintain a drill stopping state. The anchor rod machine can automatically drill, automatically pull the drill after automatic drilling, and automatically stop after automatic drill pulling, and the degree of automation is high, the labor intensity of workers is low, and the working efficiency of the anchor rod machine is high.
