Fig. 2 is the control principle figure that is controlled by the actuating unit of Fig. 1 Programmable Logic Controller.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
Like Fig. 1, shown in 2; A kind of control system of cantilever reclaimer; Comprise that the movable motor 1 of a control cantilever reclaimer sway, feeding motor 2 that a control feeding belt rotates, claw motor 3, a control that a control claw belt rotates gets the Programmable Logic Controller 4 and that the elevator, of material claw rise and fall is built-in with program module and be used for interactive man-machine interface 5; Programmable Logic Controller 4 links to each other with Central Control Room upper computer 6 through network interface; Man-machine interface 5 links to each other with Programmable Logic Controller 4; On the operation interface of man-machine interface 4, be provided with startup, stop, suddenly stop, reset and five touch key-press of control/field control change-over swith far away, also be provided with the anxious indicator lamp, distributing belt of stopping on the man-machine interface and be ready for run indicator, movable motor and be ready for run indicator, always be ready for indicator lamp, always run indicator, resultant fault indicator lamp.
At the last coil KM1 of control movable motor 1 first AC contactor that just changeing, reversing, the coil KM2 of second AC contactor of being connected with respectively of first, second mouth Y0, the Y1 of Programmable Logic Controller; Three, the 4th mouth Y2, the last coil KM3 of the 3rd AC contactor of controlling feeding motor 2 and 3 rotations of claw motor and the coil KM4 of the 4th AC contactor of being connected with respectively of Y3, this system also is provided with circuit breaker Q F1, QF2, the QF3 that controls movable motor 1, feeding motor 2, claw motor 3 power supplys respectively; Five, the 6th mouth Y4, last the 5th AC contactor KM5, the 6th AC contactor KM6 that is connected with the control winch action respectively of Y5.
On first, second input end of Programmable Logic Controller, be connected with first, second magnetic switch JS1, the JS2 that are installed in cantilever reclaimer walking track right ends respectively; Be used to detect the position of reclaimer; When reclaimer was met the first magnetic switch JS1 on the left side, reclaimer will be delayed time a period of time toward the right walking; If reclaimer is met the second magnetic switch JS2 on the right, reclaimer just time-delay is walked to left direction.Three, be connected with front limit switch S 1, the back limit switch S2 that is installed on the elevator on the four-input terminal, be used to detect claw and when lowest order and most significant bit, send signal to Programmable Logic Controller.Be connected with the first pull switch S3, the second pull switch S4 on the 5th, the 6th input end of Programmable Logic Controller respectively; The first pull switch S3, the second pull switch S4 are installed in the two ends of feeding belt and claw belt respectively; Pull switch is used for when abnormal condition appear in feeding belt or claw belt sending to Programmable Logic Controller reports to the police or self-stopping signal, stops through the programming control reclaimer.Be connected with on the 7th input end of Programmable Logic Controller one be installed in cantilever front end claw leather belt roller one side the electronic switch KS that tests the speed, the K switch that tests the speed S be a band induction near switch, be installed in cantilever front end claw leather belt roller one side.Claw leather belt roller revolution is moving a week to test the speed inductive switching once; The switch that tests the speed is set the operating condition that delay time detects the claw belt through program; When skidding appearred in the claw belt or other disorderly closedown situation occur, claw leather belt roller rotating speed was lower than normal speed or does not change, and send signal to Programmable Logic Controller this moment; Program in the Programmable Logic Controller is sent breakdown signal indication and shutdown through the signal that receives judgements of delaying time.Be connected with the first limit switch SQ1, the second limit switch SQ2 on the 8th, the 9th mouth of Programmable Logic Controller respectively; First limit switch and second limit switch are installed in the outside of first magnetic switch and second magnetic switch respectively; Lean on the rail end position; When being used for the magnetic switch et out of order, can stop movable motor through limit switch.
The principle of work of the utility model is: the operation of cantilever reclaimer always has three kinds of patterns: manual, automatic and middle control pattern.Each pattern all must be switched through the switching button on the man-machine interface, on man-machine interface, has corresponding indicator lamp to show that the indicator lamp that is transformed into the sort of this kind of pattern pattern is just bright.Only be transformed under the corresponding pattern, just can operate accordingly.Manual mode is on touch-screen, to carry out single-set operation, carries out the operation of a series of single actions, the startup of single motor and stopping.Automatic mode is on touch-screen, to have organized and group is stopped, and organizing is that order according to cantilever reclaimer electric motor starting is carried out, and stopping also is that order according to motor is stopped.In the control pattern be to remove at various breakdown signals, the various signals of being ready for send actuation signal by middle control should be ready for the time, start according to the boot sequence of motor, stopping also is that order according to motor is stopped.
Whole procedure design is according to the mode of getting material back and forth, and the cantilever reclaimer is in service to commutate through the collision limit switch, in the moment of switching-over, descends through delaying time and to get the material claw, and delay time can be changed the time number through man-machine interface.Claw rises and descends all has the spacing parking of limit switch.The claw rise and fall all have fast and two kinds at a slow speed, and the automatic lowering process is through realizing at a slow speed.
Automatic and middle control has chain restriction when driving reclaimer, when driving the claw motor, must drive feeding belt, prevents that the material that claw is got from not having the belt operation, stopped up claw.
Realize that single-set operation must forward change-over swith the control box master mode to or on touch-screen, carry out the button release, can see when pressing the button that button is in the state of flashing, expression is under the release situation now, can carry out single-set operation.
Operation under automatic condition is switched the service direction of movable motor through magnetic switch, runs into left side magnetic switch, the movable motor edge direction operation of turning right; Run into the right switch, movable motor walking toward the left side.When whole reclaimer during at midway location, to remember through the direction that memory switch (set in the program and reset) will stop last time, last time, the direction of walking was exactly the direction that starts walking once more, and just operating personal needn't be worried the situation of walking automatically.
The startup of claw motor has speed switch to detect, and judges the running condition of claw belt through the contact electronic switch, does not just send the belt failure message if in seconds detect the belt signal, stop the claw motor, carries out break down maintenance.
In addition, in the touch-screen information frame can real time recording each information of start, comprise failure message.Very convenient like this for the maintainer provides failure message, quick fault location point.
The reclaimer performance can realize two kinds of mode of operations back and forth: on-the-spot pattern and control pattern far away.All operations all is a soft operation, i.e. all operations instruction is all returned earlier to Programmable Logic Controller, sends operating instruction by Programmable Logic Controller then, drives intermediate relay, and then makes equipment operation by the relevant contactless switch energized of intermediate relay driving.
Under control pattern far away, by Central Control Room equipment is sent driving command, reclaimer is operation automatically under the driving of middle control program, and it is to get material back and forth that reclaimer is got material.The execute-in-place pattern is by touch screen operation.
