Abstract

The invention relates to a control system of a pneumatic roof bolter to solve the problems that an existing control system of a pneumatic roof bolter is singular in control mode and inconvenient to operate. The control system of the pneumatic roof bolter comprises an air path control part and a water path control part. The air path control part comprises an air source, a first quick-change connector, a first filter, a supporting leg control valve, a motor control valve, a quick exhaust valve, a pneumatic motor and an exhaust silencer. The water path control part comprises a second quick-change connector, a second filter and a feed water valve. The air source is communicated with the air inlet end of the first filter through the first quick-change connector. The air outlet end of the first filter is communicated with the air inlet end of the supporting leg control valve and the air inlet end of the motor control valve. The air outlet end of the supporting leg control valve is communicated with the air inlet end of the quick exhaust valve. The air outlet end of the motor control valve is communicated with the air inlet end of the pneumatic motor. The control system is suitable for the pneumatic roof bolter.

Description

technical field [0001] The invention relates to a pneumatic rock bolt control system, in particular to a pneumatic rock bolt control system. Background technique [0002] Pneumatic bolter is a drilling tool in coal mine roadway bolt support work, which can improve the support effect, reduce support cost, speed up the roadway, reduce auxiliary transportation volume, reduce labor intensity, improve the utilization rate of roadway section, etc. has very prominent advantages. During the working process of the pneumatic rock bolter, it needs to be equipped with a special control system to control the pneumatic rock bolter to ensure the continuity and reliability of its work. Practice has shown that due to the limitation of its own structure, the existing pneumatic rock bolter control system generally has the problems of single control mode and inconvenient operation, so it is difficult to meet the high-efficiency production requirements of coal mines. Based on this, it is neces...
