The working principle of belt tensioning is that under an automatic control mode, a hydraulic station 2 is started, and then an electromagnetic valve controls to charge oil to a tensioning buffer mechanism 1 consisting of a buffer oil cylinder and an energy accumulator. When the oil filling pressure enables the tensile force of the steel wire rope to reach the set upper limit (the specific numerical value can be set according to the actual requirements on the site), the electromagnetic valve controls to stop oil filling. At the same time, the controller 5 sends a signal that the belt conveyor can be started, and the belt conveyor is started and runs at an accelerated speed. After the belt conveyor reaches a constant-speed running state, the controller 5 controls the electromagnetic valve to release pressure to the tensioning buffer mechanism 1, and tension is reduced. When the tension of the conveying belt is reduced to a value required by normal operation, the tensioning buffer mechanism 1 is self-locked to maintain the tension of the belt, and the hydraulic station 2 stops working. The tension of the belt is automatically monitored by the tension sensor 4. Once the tension is found to be less than 0.95 times the set "lower limit", it will restart the tensioner damping mechanism 1 by the controller 5, increasing the belt tension to the set lower limit. After the adjustment is finished, the tensioning is automatically stopped.
