Abstract

The invention discloses a cantilever tunneling machine and a tunneling control method thereof. The cantilever tunneling machine comprises a horizontal adjusting oil cylinder, a vertical adjusting oilcylinder and a control unit, wherein the horizontal adjusting oil cylinder and the vertical adjusting oil cylinder are used for adjusting an angle of a cantilever and connected with the control unit through proportional valves; a transverse rotary encoder and a longitudinal rotary encoder are arranged on the cantilever and used for detecting a horizontal angle and a vertical angle of the cantilever respectively and sending the horizontal angle and the vertical angle to the control unit; and the control unit is used for controlling the horizontal adjusting oil cylinder and the vertical adjusting oil cylinder to act through the proportional valves. According to the cantilever tunneling machine and the tunneling control method thereof, the oil cylinders are controlled by the proportional valves to act and the rotary encoders are arranged and used for measuring angle information, so that automatic adjustment and closed loop feedback control for the angle of the cantilever are realized, theposition accuracy of the angle of the cantilever is relatively high, and the forming quality of a tunneling roadway is improved. Besides, manual operation is replaced with automatic control, the labor intensity is reduced, and the safety performance is improved.

Description

technical field [0001] The invention relates to the technical field of coal mine excavation, in particular to a cantilever type excavation machine and an excavation control method thereof. Background technique [0002] The cantilever roadheader is a combined unit capable of cutting, loading and transporting, self-cleaning and spraying and dust removal. In the prior art, when coal mining is excavated, the driver of the professional excavator carries out tunnel excavation according to the blueprint and simple laser beam pointing. After a certain distance is excavated forward each time (the feed distance is determined depending on the roof condition, which has a great human factor), artificial bolt support and grouting operations are carried out, and then continue to excavate forward, so reciprocating. Or, uniformly configure switching solenoid valve groups, short-distance remote control and video detection equipment on the roadheader, and the driver can perform remote cutting...
