Roadheader, system and method

Abstract

The invention provides a roadheader, a system and a method. According to the roadheader, the system and the method, three-dimensional space coordinates of the roadheader can be tracked and measured inreal time to realize the millimeter levelpositioning accuracy of the set distance within the visual range, remote control operation and automatic control over the roadheader are facilitated, and themovement path and the speed of a cutting head as well as the direction, position and posture of a roadheader body can be automatically adjusted according to the position change of the roadheader and the rock wall hardness change of a heading working face roadway.

Description

technical field [0001] The present disclosure relates to a boring machine, system and method. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] As an important mechanical equipment in mining, the roadheader is mainly used in mine roadway excavation projects. The key technology of the intelligent control of the roadheader is mainly the automatic control of the roadway section forming and the control of the driving direction. In the process of the automatic control of the roadway section forming, how to automatically control the cantilever of the roadheader to drive the cutting head to carry out the cutting operation in the roadway section operation , Cutting out the specified cross-sectional shape according to the design path is the key to the technology. At present, some roadheaders can perform automatic cutting when the fuselage coordina...

AI Technical Summary

Problems solved by technology

At present, some roadheaders can perform automatic cutting when the fuselage coordinates are fixed and the attitude remains unchanged. However, because the roadheader is disturbed by the impact of rocks during the excavation process, the fuselage coordinates and attitude are constantly changing, so it cannot be truly realized on site. automatic cutting

[0004] In order to adjust the position of the roadheader according to the tunneling situation, some manufacturers use cameras, infrared cameras, and thermal imaging cameras to monitor the section in real time to assist workers in remote control operations. However, due to the relatively large dust on site, it is invisible during the cutting process. low efficiency

If accurate remote control operation is required, precise positioning of the roadheader body is required. However, due to the relatively closed tunnel, the signals of satellite positioning systems such as GPS and Beidou cannot be covered, so the positioning system can only be built independently

At present, the positioning methods widely used in the roadway, such as UWB, ZIGBEE, Wi-Fi, Bluetooth, RFID and other technologies, the positioning accuracy cannot reach the millimeter level, and cannot meet the requirements of the remote control operation of the roadheader.
