FIG. 3 is a schematic circuit diagram of an embodiment of the present invention with a reset button.
Reset button theory of operation: the reset button is a common normally closed button, when the normally closed button is pressed, the normally closed contact is disconnected, and when the button is released, the normally closed contact is closed. The function of the reset button in the modified circuit is as follows: after the belt conveyor is in a heavy deviation shutdown state, in order to start the belt conveyor within the first time under the condition that the two-stage deviation switches are not reset, the heavy deviation signal can be disconnected as long as a reset button is pressed, and the belt conveyor is started, so that conditions are created for correcting the belt deviation. After the belt deviation adjusting work is finished, the vertical rollers of the two-stage deviation switches can automatically reset and return to the initial state.
The invention has substantive characteristics and obvious technical progress, the resettable two-stage deviation switch installation method of the belt conveyor of the invention, install a reset button box on the control circuit in front of every group of deviation switches, once the belt conveyor takes place the heavy deviation, as long as press all reset buttons in front of deviation switch producing the heavy deviation signal, cut off all heavy deviation signals, can start the belt conveyor again, and can adjust and correct the deviation of the belt through the correction roller in the middle of the operation of the belt conveyor, solve the belt heavy deviation shut-down phenomenon caused by overlength of belt and belt load nonuniform, and under the situation that the two-stage deviation switch does not reset, the problem that can't start the belt conveyor.
The invention relates to a mounting method of a resettable two-stage deviation switch of a belt conveyor, which is applied to the engineering of an American headquarters SL2 belt conveyor system, wherein the project is located in the American headquarters and headquarters, the total length of the belt conveyor system of the project is 4.5 kilometers, the project is divided into 10 belt conveyors, the longest belt conveyor length is 900 meters, the belt conveyor width is 1.6 meters, the rated conveying capacity of the belt conveyor is 4000 tons per hour, and 1 pair of resettable two-stage deviation switches is arranged at the middle position of the belt conveyor every 35 meters because the belt of the whole belt conveyor is longer. In the no-load linkage test run process, the phenomenon of heavy deviation and shutdown of the belt sometimes occurs due to the fact that the length of the conveying system of the single belt conveyor is long. Meanwhile, in the process of load linkage test run, because the belt conveyor runs under load, the phenomenon of heavy deviation and shutdown can occur due to uneven belt load. And analyzing according to the working principle of the two-stage deviation switch, and starting the belt conveyor again only after the heavy deviation signals are completely eliminated. Similarly, according to the principle of belt deviation adjustment, the belt deviation adjustment work cannot be performed in the shutdown state of the belt conveyor, and only after the belt runs, the belt deviation adjustment can be performed.
The problem that the belt cannot be started under the condition that two-stage deviation switches are not reset is solved. By adopting the resettable two-stage deviation switch installation method for the belt conveyor, a reset button box is additionally arranged on the control line in front of each group of deviation switches, and the control line is changed. Once the belt conveyor is heavily deviated, as long as press all reset buttons in front of the deviation switch that produce heavy deviation signal, cut off all heavy deviation signals, can start the belt conveyor once more to can adjust the off tracking of belt through rectifying the roller in the middle of the belt conveyor operation.
