The invention discloses an intelligent protection system of a long-distance belt conveyor. The intelligent protection system of the long-distance belt conveyor comprises a plurality of pull rope switches, a plurality of amplified phones; at least two pairs of off-tracking switches, a smoke sensor, a speed sensor, a controller, a ripping sensor and a material quantity detecting device, wherein eachamplified phone is matched and connected with one pull rope switch; the smoke sensor is disposed above a driving roll of a machine head of the belt conveyor; the speed sensor is disposed below the machine head of the belt conveyor; the controller is connected with one amplified phone located over the machine head and is connected with the smoke sensor and the speed sensor; the ripping sensor is disposed at a machine tail of the belt conveyor and connected with one amplified phone which is located over the machine tail; and the material quantity detection device is disposed at the machine tailof the belt conveyor and connected with the amplified phone which is located over the machine tail. The intelligent protection system of the long-distance belt conveyor is easy to mount, good in economical property and high in reliability and has complete functions.
Description
technical field [0001] The invention relates to the field of protection and control of belt conveyors, in particular to an intelligent protection system for long-distance belt conveyors matched with long-distance tunnels and subway construction shields / TBMs. Background technique [0002] The belt conveyor system has become the most important bulk material transportation system, widely used in coal mines, metallurgy, chemicals, power plants, docks, etc. The protection system provides a reliable guarantee for the efficient and safe operation of the belt conveyor. As an indispensable and important component, the belt conveyor protection system has become an important consideration in the selection of the protection system for its reliability, economy, installation and ease of use. At present, various sensors of the belt conveyor protection system are connected to the main control through hard wiring, and the main control judges the action signal for alarm protection; the rope ...
