The invention discloses a boring machine, a cutting head positioning system, a cutting system and a cutting method thereof. Wherein, the cutting head positioning system includes a vehicle body positioning detection device, a cutting head positioning detection device and an electrical control device. Wherein, the signal input end of the electrical control device is connected with the vehicle body positioning detection device and the cutting head positioning detection device, and is used to determine the position of the cutting head relative to the roadway according to the input signals of the vehicle body positioning detection device and the cutting head positioning detection device ; The signal output end of the electric control device is connected with the hydraulic system of the roadheader to drive the actuator of the roadheader for cutting operation. The invention can improve the forming accuracy of the cutting section, avoid undercutting and overcutting of the cutting section as much as possible, reduce labor intensity, improve work efficiency, and improve operation safety.
Description
technical field [0001] The invention relates to the technical field of roadheaders, in particular to a roadheader and its cutting head positioning system, cutting system and cutting method. Background technique [0002] At present, the cutting operation of the underground working face of the roadheader is all manually operated by the operator to move the cutting head left and right and up and down, so as to realize the cutting operation of the roadway section. [0003] However, when the roadheader is performing cutting operations with harsh environments, complex geology, and high rock hardness, the amount of dust and dust will be large, and the roadheader will vibrate violently, which will seriously affect the operator's sight and make the operator unable to Accurately locate the position of the cutting arm and the cutting head, thereby reducing the forming accuracy of the cutting section, so that undercutting and overcutting of the cutting section often occur. [0004] For...
