Deviation adjusting tensioning method of belt conveyer conveying belt deviation adjusting tensioning traveling trolley

The invention provides a deviation adjusting tensioning method of a belt conveyer conveying belt deviation adjusting tensioning traveling trolley. According to the method, hydraulic lifting oil cylinders on the front sides and the rear sides of four wheels installed on a tensioning trolley frame act on the inner sides of trolley rails, the acting directions of the oil cylinders are adjusted according to different deviation conditions of a conveying belt, corresponding torque is formed for the whole frame, small-angle deviation is formed between the frame and the operating direction of the conveying belt, in the operating process of the conveying belt, the deviation phenomenon of the conveying belt is gradually corrected, a hydraulic control system is adjusted, the oil cylinders retract, interference generated by rigid contact is eliminated, and constant tension needed for normal operation of a belt conveyor is restored. By the adoption of the method, under the condition that the belt conveyor is normally operated, deviation adjusting tensioning of the conveying belt is conducted on the belt conveyor through the deviation adjusting tensioning traveling trolley, operation is simple, and the good effect is achieved.
