Problems solved by technology
The working environment of the fully mechanized excavation face in coal mines is very harsh, with loud noise and serious dust, which has a great impact on the health and work efficiency of the staff. It depends on the experience of the driver of the roadheader to a large extent, so in this case, the phenomenon of over-digging and under-digging of the roadway is very serious. future direction of development

The invention discloses a beyond-visual-range remote control system for a cantilever type heading machine. The remote control system consists of a signal emitter, a signal receiver, a photoelectric converter, an optical cable, a programmable computer controller PCC, an electromagnetic valve, a middle relay and an auxiliary circuit, wherein the signal emitter is a portable low-power wireless emitter with stainless steel and enhanced plastic pieces serving as a shell, and the anti-explosion form is intrinsically safe for mining; and an intrinsically safe battery is adopted to supply power. During remote control operation, the signal emitter emits a corresponding operation signal at a position 1,000 to 2,000 m away; the photoelectric converter converts an electric signal into a light signal which is transmitted by the optical cable through a long distance; the photoelectric converter then converts the light signal into an electric signal which can be identified by the receiver, and the electric signal is input into the PCC; the output function of the PCC drives each mechanism of the heading machine to complete each action; and by the combination with a remote monitoring system of the heading machine, the heading machine can be observed and adjusted in real time. The beyond-visual-range remote control system has the advantages of low cost, high precision, simplicity in operation and the like, and can control the cantilever type heading machine on a heading face at a position thousands of meters away.
Description
Technical field: [0001] The invention relates to the technical field of remote control of coal mine underground tunneling equipment, in particular to a remote control method of a cantilever type tunneling machine based on the principle of over-the-horizon control. Background technique: [0002] The cantilever roadheader is a very important type of underground mining equipment. It is the most widely used tunneling equipment in the mechanized production of fully mechanized coal tunnels in my country. It is mainly used for cutting partial sections. Its outstanding structural features are A telescopic swingable cantilever is installed on the turret, and a cutting head is installed at the front end of the cantilever. Through the swing of the cantilever and the rotation of the cutting head, the coal and rock can fall off. The operation table of the roadheader can control the operation of the cutting head. The track is controlled, and various shapes can be cut, such as rectangular, a...
