Be contained in respectively on the machine left and right sides door hanging plate 11 and 3 with linear electric motors elementary 4 contacted about two door guide roller assemblies 9 place (as shown in Figure 4) on the guide rail 8, door opening machine for elevator for the driving of separate unit linear electric motors, be contained on the right door hanging plate of a machine and place on the guide rail 8 with linear electric motors elementary 4 contacted right door guide roller assemblies 9, and left-hand door pulley assembly 9 is fixed on the machine left side door hanging plate 11 and places (as shown in Figure 1) on the guide rail 8, guide rail is fixed on the machine bottom board, by about two guide wheel assemblies 10 respectively two door hanging plates 11 about the door machine and 3 are fixed on the guide rail; Door cutter 5 is fixed on the left door hanging plate, the door cutter hook 6 supporting with the door cutter is installed on the door lifter base plate, and door cutter and door hanging plate are synchronized with the movement, and guarantees that Room door, gate are synchronized with the movement in switch door process, having overcome windage causes Room door to close the phenomenon that forces elevator to be stopped transport with the gate interlock.
The right contact of door machine contact contact 14 is installed on the right door hanging plate 3 of a machine by door machine contact holder 15, and left contact is installed on the door lifter base plate 1 by door machine contact support 13.
Intermediate buffering block assembly 12 is installed between right door hanging plate 3 of a machine and the door machine left side door hanging plate 11, when making the elevator door-closing in-place, a door machine left and right sides door hanging plate does not clash into, and the vibrations can reduce the elevator door door-closing in-place time, make the motion of elevator door more steady, noise is littler.
Shown in Figure 2 is the cartridge type permanent magnetic moving winding linear motor door-opening machine that two linear electric motors drag pattern, different with Fig. 1 is: elementary 4 of two linear electric motors are installed in respectively on right door hanging plate 3 of a machine and the door machine left side door hanging plate 11, two linear electric motors secondary 2 be installed in respectively a machine bottom board 1 about on two linear electric motors secondary fixed seats 16 (linear electric motors secondary fixed seat 16 directly is connected with a machine bottom board 1), after linear electric motors 4 energisings, produce electromagnetic force between linear electric motors elementary 4 and the linear electric motors secondary 2 and promote a door machine left side, right door hanging plate 11, move back and forth about 3 works.Interlock wire rope 18 by interlock pulley set 7 makes their synchronous reciprocating motions, realizes elevator open and close door.
Intelligent driven controlling system as shown in Figure 5 and Figure 6, the cartridge type permanent magnetic moving winding linear electric motors that drag pattern with the separate unit linear electric motors of Fig. 1 are that example is described below:
Door lifter is driven by cartridge type permanent magnetic moving winding linear electric motors (PLSM).PLSM time level 2 is made up of cartridge type permanent magnet and iron staff, be installed on the machine bottom board 1, and be fixed.Elementary 4 of PLSM is made up of armature core and three phase windings, is installed on the right door hanging plate 3 of a machine, moves with door.Three phase windings are done Y-connection, and three winding overhang U, V, W are connected to the inverter output end of controller.The theory diagram of driving control system as shown in Figure 5.Control module wherein is exactly the CPU of a chip system, maintenance instruction be a 0V or+data signal of 5V (representative " maintenance " or " normally moving " respectively), directly receive on the pin of CPU.When this instruction when " maintenance ", CPU sends " overhauling " signal by its pin to main frame, and the instruction of reading " opening the door " or shut the gate from a local switch by another pin.Otherwise when " normal operation ", CPU sends " it is invalid to overhaul " signal to main frame, and the instruction of reading " opening the door " or shut the gate by another pin from main frame.
Driving control system is that the inverter of being made up of three phase mains, rectification module and Intelligent Power Module IPM by as shown in Figure 6 is to the PLSM power supply.The dc source of inverter is obtained through three-phase diode rectification and capacitor filtering by three-phase 380V AC power.Inverter is made of the IGBT of three-phase intelligence merit module (IPM).Realize the speed and the Position Control of elevator door.The traffic direction of PLSM is also controlled by CPU.CPU utilizes inner A/D converter sample rate current signal, calculates the three-phase transient current of PLSM then in conjunction with switching states.Realized time real detection the around electric current to PLSM like this, if overcurrent condition takes place, CPU will turn-off all unit of IPM at once, recover original triggering state again after waiting electric current to fall back to allowed band.
In the process that elevator door cuts out, if foreign matter blocks door, except detecting with hardware such as light film, baffle plates, CUP also will be by judging PLSM running status (for example speed and electric current).In case discovery foreign matter, CPU will be controlled PLSM inverted running (action of promptly opening the door) at once, and guarantee that impact to foreign matter is less than 150N.
Open or close when putting in place when elevator door, CPU turn-offs all unit of IPM, and the time real detecting gate the position.And detecting because of the external force effect oppositely when mobile, CPU will power to PLSM by inverter again, will keep door to be in out like this or close the state that puts in place.But the thrust that this moment, PLSM produced is about 150N, and like this, car door is shut or opened to the foreign compulsion that allows to surpass 150N.
At last, CPU also carries out the RS232 serial communication by its two pins and a hand held debugger, when installing or overhaul elevator, can use the hand held debugger that controller is provided with some necessary parameter, for example, the shift motion of the speed of service curve of door, door, or the like.
Two linear electric motors drag the door lifter of pattern, and it is identical that its intelligent driven controlling system and separate unit linear electric motors drag the pattern door lifter.
