Folding-arm type tunneling machine capable of monitoring intelligently and automatically regulating rotate speed of cutting head

Abstract

The invention discloses a folding-arm type tunneling machine capable of monitoring intelligently and automatically regulating the rotate speed of a cutting head. The folding-arm type tunneling machine comprises a working arm, a conveying mechanism (11), an electrical system (10), a hydraulic system (5), a travelling mechanism (8) and a vehicle body (7); the working arm comprises the cutting head (1), a spraying frame (2) and a large arm (4); one end of the working arm is movably connected with the vehicle body; sensors used for monitoring gas, dust and displacement are arranged on the cutting head respectively; a temperature sensor and a pressure sensor are arranged on a pipeline of the hydraulic system; monitored data of the sensors is transmitted to the network through an optical fiber cable, so that real-time on-line monitoring and remote control are realized, the rotate speed of the cutting head can be regulated automatically, and the feed rate can be reduced, so as to ensure that the tunneling machine performs tunneling operation safely; when the rigidity of a to-be-cut object is higher than the cutting rigidity, the tunneling speed is reduced, and when fluffy coal is cut, the rotate speed of the cutting head is increased automatically, and the feed rate is increased, so that not only can the tunneling rate be ensured, and damage to equipment can be lowered, but also the construction safety can be ensured.

Description

technical field [0001] The invention relates to a cantilever type roadheader, in particular to a folding arm type roadheader which can intelligently monitor the working environment, automatically adjust the rotating speed of the cutting head and control the cutting amount, and the working arm can perform excavation operations. Background technique [0002] During the 12th Five-Year Plan period, the merger and reorganization of coal mines across the country has been accelerated. From the perspective of safety, the state has enforced the mechanization of coal mining. The roadheader has been widely used in the tunneling construction of coal mines, non-coal mines, railway tunnels, hydropower projects and other roadways. With the integration of coal mine resources in our country, the development of coal mine enterprise conglomerates, the scale of coal mine mining has expanded, and the degree of mechanized construction has become higher and higher. As safety production has become...
