example 1
[0050] Combined with the signal records generated by belt deviation during a certain belt conveyor operation, this figure describes the control process of the present invention in detail:
[0051] T1-T6: The extension and contraction range of the push rod is represented by the running time of the motor;
[0052] t1: The belt slightly deviates to the right, and the push rod is retracted for T=2 seconds;
[0053] t1+10s: Delay 10s to detect again, the belt has not deviated, and the push rod does not move;
[0054] t2: The belt deviates slightly to the left, and the push rod is stretched out for T=2 seconds;
[0055] t2+10s: Delay 10s to detect again, the belt still deviates to the left, and the push rod continues to extend for T=2 seconds;
[0056] t3: The belt deviates lightly to the right. The deviation direction at time t3 is opposite to that at time t2+10s and the time interval is less than 3 minutes, that is, t3-(t2+10 seconds)<3 minutes. It is determined that the system en...

The invention provides a belt conveyor deviation adjusting device, a deviation correcting carrier roller is arranged at the lower part of the return belt and is in contact with the belt, one end of the deviation correcting carrier roller is a fixed end, and the other end is a moving end; the deviation direction of the moving end is adjusted by a motor; the device also comprise deviation switches arranged on both sides of the belt, the deviation switches are connected with a control system, the control system is connected with the motor, and the control method of the belt conveyor deviation adjusting device is also provided. The method comprises the following steps: (1) when the belt deviates to the left, the motor rotates forward and a push rod extends out; 2) when the belt deviates to theright, the motor rotates reversely for 2 seconds and the push rod retracts back; 3) when the belt deviates to the right at the last time and deviates to the left at this time, the motor rotates for T / 2 seconds, the push rod extends out, and T is the adjusting time for the last deviation; 4) when the belt deviates to the left at the last time and deviates to the right at this time, the motor rotates reversely for T / 2 seconds, the push rod retracts back, according to the method, the belt can be timely adjusted when deviating, and the normal operation of the belt conveyor is effectively guaranteed.
Description
technical field [0001] The invention relates to the operation of a belt conveyor, and is a new control method for automatic detection and adjustment of belt deviation correction. Background technique [0002] The automatic deviation correction method of belt conveyor is a new method to deal with deviation of belt conveyor. At present, the deviation correction methods and characteristics of belt conveyors in port enterprises are roughly divided into the following types: [0003] (1) Drop point adjustment: adjust the belt operation by adjusting the drop point position and angle of the material on the belt. This method has a small adjustment range and is inconvenient for frequent adjustments. The flow of the material itself fluctuates frequently, and the effect of adjusting the belt deviation by adjusting the feeding point is not obvious. [0004] (2) Correction roller adjustment: adjust the belt running by changing the angle value between the roller shaft and the belt runnin...
