Embodiment 1
The heavy 120kg of certain power station canal head of water diversion advance and retreat sluice gate locking beam, the heavy 120kg of walking mechanism, selects track model 9kg/m, traveling mechanism wheel footpath: 160mm, the speed of service ~ 1.5m/min, electrical speed 1320 revs/min.
Design speed is reached by Acceleration of starting state in setting 1 second:
Dynamic moment of inertia: J=mR*R/2=0.768;
Angular acceleration: α=n*360/57.3/60=138.22;
Moment of torsion: T=J* α=106.15NM;
Power: P=T*n/9550=14.67W;
Power taking machine service factor is 1.5, and just can determine power of motor is 14.67*1.5=22w;
Look into micromachine type selecting data: choosing motor is 25w, and 1:10 chosen by intermediate reduction gear case, and in right angle, real reduction box chooses 1:60;
The traveling mechanism speed of service: 1.105m/min;
Finally choose motor and reducing gear model: 25YS120DV thereof.
This project forward and back sluice gate and gate electric lock device weight are less than 15000kg, and the heavy 120kg of locking beam, so arrange single electric drive, is directly passed to the weight of gate on gate slot 7 and its concrete by gate electric lock beam, walking mechanism, track.Drive motors Direct driver locking beam driving wheel, for ensureing the synchronous of gate electric lock beam both sides driving wheel and driven pulley, arrange a shaft coupling and connect driven pulley, walking mechanism drives locking beam along track back and forth movement.
This project drive motors selects the minitype speed reducing motor with self-locking and rotating function, and operating voltage is AC220V, respectively arranges a limit switch, be convenient to lock the supervision put in place in gate electric lock beam stroke first and end.
Remote control table comprises that to grind magnificent Industrial Personal Computer (IPC) a set of, Industrial Personal Computer (IPC) is provided with video frequency collection card, now PLC control cabinet one side, the low-voltage electrical elements such as Siemens S7-1200PLC, KTP touch-screen, gate height loading instrument, frequency converter and Schneider air switch, contactor, line breaker, relay are set, use Siemens's rich way STEPV11 programming software.Now PLC control cabinet is connected with gate electric lock beam, headstock gear, servicing lighting and controls, and is provided with wired the overlapping with UNICOM 3G wireless two of optical fiber and communicates, for subsequent use each other, switches voluntarily.Now PLC control cabinet receives Industrial Personal Computer (IPC) instruction, and upload that gate hoist runs aperture, gate load, the locking of electric lock beam put in place in real time, electric lock beam exit put in place, signal and the data such as auxiliary lighting system switch.
In the present embodiment, gate Full-automatic remote control system operating principle is as shown in Figure 1:
Industrial Personal Computer (IPC) realizes long-range crawl and automatic controlling gate electric lock beam, gate hoist and servicing lighting, watch-dog by existing ground PLC control cabinet.When operations staff carries out the operation of long-range crawl, instruction is assigned to existing ground PLC control cabinet by Industrial Personal Computer (IPC), now PLC completes the operation of gate electric lock device, gate hoist by the electrical equipment such as control relay, contactor, now by the running status of monitored picture monitor gate electric lock device, gate hoist.
Operations staff carries out remote auto when controlling, and is also assign instruction by Industrial Personal Computer (IPC) to existing ground PLC control cabinet, the now position of PLC control system automatic decision gate electric lock device now.When gate to be in gate slot 7 and gate electric lock device be in lock-off put in place state time, directly start headstock gear and keying operation carried out to gate; When gate to be in gate slot 7 and gate electric lock device be not in lock-off put in place state time, now first PLC starts gate electric lock device, gate electric lock device moves to after lock-off puts in place, the lock-off limit switch that puts in place sends signal and cuts off gate electric lock device power supply, starts headstock gear and carry out keying operation to gate after time delay 5S.After gate moves to the given aperture of existing ground PLC, now PLC is automatically by the operation of relay, contactor, line breaker stopping headstock gear.
When gate is in the open range of gate electric lock device, Industrial Personal Computer (IPC) is given after now PLC control cabinet assigns operational order, and now PLC first-selection judges gate electric lock device position.Now PLC is according to the height of gate height loading instrument, put in place the signal of limit switch of loading data and automatic valve locking device locking judges that automatic valve locking device is in latched position and gate is seated on gate electric lock device, now PLC first sends headstock gear and opens the instruction rising 10cm, after headstock gear opens liter stopping, time delay 5s sends the instruction of gate electric lock device lock-off, when gate electric lock device moves to its limit-switch positions, limit switch sends lock-off and to put in place signal, now PLC stops the action of gate electric lock device, send headstock gear after time delay 5S to open, close instruction.When gate hoist moves to after instruction aperture (during now PLC programming instruction pre-add 10cm), headstock gear stops opening and closing.After time delay 5s, now PLC sends out gate electric lock device lock instruction, gate electric lock device moves to locking bit and after its limit switch action, now PLC sends out and stops gate electric lock device action command, time delay 5S now PLC sends out headstock gear closedown 10cm instruction, after gate hoist cuts out and puts in place, now PLC sends out the instruction of headstock gear phase down.Now gate just drops on gate electric lock beam, and the operational order that now Industrial Personal Computer (IPC) is assigned completes.
Operations staff carries out existing ground PLC and controls identical with remote control operation principle, and the operation that now PLC controls is uploaded to Industrial Personal Computer (IPC) equally automatically.
In sum, be only one of patent Example of the present invention, do not limit the scope of patent working of the present invention with this, as long as the equivalence that the content of foundation the present patent application patent is done changes and modifies, all should as technology category of the present invention.In addition, not state part same as the prior art for patent of the present invention.
