The invention relates to the belt conveyer driving technology, in particular to a driving device of a permanent-magnet frequency-conversion belt conveyer, which solves the problems that when the existing driving device is adopted for driving the belt conveyer, the driving efficiency is low, the starting is not stable, the driving device is difficult to start when in heavy load, and the belt conveyer is high in failure rate. The driving device of the permanent-magnet frequency-conversion belt conveyer comprises a conveyer belt, and a driving device connected with a rotary drum of the belt conveyer; the driving device comprises a permanent-magnet synchronous motor; an output shaft of the permanent-magnet synchronous motor is connected with the rotary drum of the belt conveyer; and a power input end of the permanent-magnet synchronous motor is connected with a frequency converter. According to the driving device, the characteristics of the permanent-magnet synchronous motor and the speed regulating function of the frequency converter are combined, the gearless permanent-magnet synchronous frequency-conversion driving to the belt conveyer can be realized, so that the problems that when the existing driving device is adopted for driving the belt conveyer, the driving efficiency is low, the starting is not stable, the driving device is difficult to start when in heavy load, and the belt conveyer is high in failure rate can be solved effectively, and the belt conveyer is suitable for the driving of the underground belt conveyer.
Description
technical field [0001] The invention relates to belt conveyor drive technology, in particular to a permanent magnet frequency conversion belt conveyor drive device. Background technique [0002] Belt conveyors (belt conveyors) are mainly used in coal mines, and are the only transportation equipment between the first-line mining equipment in the mine and the main coal belt in the roadway. At present, the belt conveyor is mainly driven by a drive device consisting of an asynchronous motor, a hydraulic coupling, and a reducer. The problems brought about by this driving method are: 1. Due to the inherent characteristics of the asynchronous motor itself, the driving efficiency is low, the starting is not stable, and it is difficult to start with heavy loads. 2. Since the hydraulic coupler and reducer are easily damaged under long-term working conditions, the failure rate of the belt conveyor is high, which in turn affects the downhole production efficiency. Based on the above t...
