First embodiment:
As shown in Figure 1, the elevator system of saving oneself of present embodiment comprises a synchronous electrical motor 1, a band-type brake 2, a band-type brake coil 3, a button 4, a fault detector 5, open contact 6 and a short unit 10.
Wherein said synchronous motor 1 is electrically connected with said short unit 10 through said open contact 6; Said short unit 10 is used for said motor short circuit is connected; Said band-type brake coil 3 is connected with said band-type brake 2 and when said band-type brake coil 3 conductings, said band-type brake 2 is opened, this moment the lift car setting in motion; Otherwise band-type brake 2 braking lift cars, elevator remains static.Present embodiment is realized the releasing action of band-type brake 2 through the band-type brake coil in the control band-type brake 2.
Said band-type brake coil 3 also is connected with said button 4, when the user pushes said button 4, and said button 4 and said band-type brake coil 3 conductings, the loop of formation makes the also conducting of said band-type brake coil 3.The user controls the release of said band-type brake 2 in the present embodiment through the said button 4 and the conducting of band-type brake coil 3.
When elevator produces fault; Said fault detector 5 makes said open contact 6 closures; Thereby make said synchronous motor 1 through said short unit 10 short circuits; Thereby the control loop when making the elevator normal operation lost efficacy, thereby when elevator faults, and the save oneself running of system's control elevator of the elevator of present embodiment is only arranged.
The principle of work of present embodiment is following:
When the elevator normal operation, said fault detector 5 does not detect elevator faults, so said open contact 6 is in opening.
Because said open contact 6 is in opening; So synchronous motor 1 is short circuit not; So the operational system in the elevator can normally be controlled the normal operation of synchronous motor 1 and band-type brake 2 realization elevators, for example controls the operation of synchronous motor 1 through frequency converter.
When elevator faults, said band-type brake 2 must make said elevator remain static, thereby guarantees user's security; And said fault detector 5 detects elevator faults, and makes said open contact 6 closures.This moment, synchronous motor 1 was through said short unit 10 short circuits.
After this when the user pushes said button 4, because conducting between said button 4 and the band-type brake coil 3,, thereby make said elevator cab movement so band-type brake coil 3 makes said band-type brake 2 releases.The motion of lift car at this moment drives the rotation of said synchronous motor 1, promptly on said synchronous motor 1, has applied a torque.
Because said synchronous motor 1 rotates, and can produce electro-motive force in the said synchronous motor 1.And because open contact 6 closures, said synchronous motor 1 short circuit is so the electro-motive force that said synchronous motor 1 produces generates electric current and flows into the short circuit loop of said short unit 10.This moment, synchronous motor 1 in-to-in also correspondingly generated the opposing torque electric current; Thereby at the inside of said synchronous motor 1 generation counter electromotive force; Thereby said counter electromotive force makes and produces opposing torque in the said synchronous motor 1, thereby opposing torque has reduced the torque on the said synchronous motor 1.
Because along with the raising of the rotating speed of said synchronous motor 1, said counter electromotive force increases, thereby opposing torque constantly rises, and when said opposing torque was identical with said torque, said synchronous motor 1 promptly got at the uniform velocity state.
After this when said button 4 was opened, said band-type brake coil 3 broke off, so said band-type brake 2 makes the lift car stop motion.
Therefore the user can be so that said lift car gets into leveling zone, thereby is convenient to saving oneself of user.
Second embodiment:
As shown in Figure 2, the difference of the present embodiment and first embodiment is that the system of saving oneself of the elevator in the present embodiment also comprises an open contact 7, and said open contact 7 is serially connected with between said band-type brake coil 3 and the button 4.
Wherein when elevator faults, said fault detector 5 is also with said open contact 7 closures, thereby makes and form path between said band-type brake coil 3 and the button 4.This moment, the user can be so that conducting between said button 4 and the band-type brake coil 3, thereby discharged band-type brake 2, thereby made said lift car entering leveling zone, so that the saving oneself of user.
Through said open contact 7 said band-type brake coil 3 and button 4 are isolated in the present embodiment, thus when preventing the elevator normal operation, misoperation of users, promptly when the elevator normal operation, the user can't control said band-type brake coil 3 through button 4 and discharge band-type brake 2.
The 3rd embodiment:
As shown in Figure 3, the difference of the present embodiment and second embodiment is that the system of saving oneself of the elevator in the present embodiment also comprises a displacement detector 8, and whether the car that said displacement detector is used to detect said elevator arrives the bottom or the top of elevator.
Displacement detector described in the present embodiment 8 is arranged between said open contact 7 and the band-type brake coil 3; The user can also be connected said displacement detector 8 according to the design and construction of elevator device with miscellaneous part in addition, and for example said displacement detector 8 is arranged between said open contact 7 and the button 4 etc.
Wherein during elevator faults; When the car that does not detect elevator when said displacement detector 8 arrives bottom or the top of elevator; Conducting between said band-type brake coil 3 and the said displacement detector 8, so band-type brake coil 3 discharges band-type brake 2, thereby the user can be through making that conducting discharges band-type brake 2 between button 4 and the band-type brake coil 3; Thereby, make elevator cab movement.
When the car that detects elevator when said displacement detector 8 arrives bottom or the top of elevator; When being the leveling zone at bottom lift car gets into or top; Break off between said band-type brake coil 3 and the said displacement detector 8, this moment, the user no longer can discharge band-type brake 2 through button 4, so at leveling zone; Said band-type brake 2 makes lift car remain static, thereby the user can be safer saves oneself.
The 4th embodiment:
As shown in Figure 4, the difference of present embodiment and the 3rd embodiment is that the system of saving oneself of the elevator in the present embodiment also comprises a variable resistance 9.Variable resistance described in the present embodiment 9 is serially connected with between said synchronous motor 1 and the said open contact 6.Said in addition variable resistance 9 can be serially connected with any position between said synchronous motor 1 and the short unit 10.
Wherein when the release of user through the said band-type brake 2 of button 4 control, the torque that puts on said synchronous motor 1 makes and generates electro-motive force on the said synchronous motor 1 that said electro-motive force likewise produces counter electromotive force in the inside of said synchronous motor 1.
Synchronous motor among the 3rd embodiment directly is connected with said short unit 10 for 1 this moment; So the electric current of the electro-motive force of synchronous motor 1 generation at this moment is very big; Thereby the counter electromotive force that correspondingly said synchronous motor 1 in-to-in opposing torque current-induced goes out is also very big, so the torque of said synchronous motor 1 and opposing torque balance soon.So lift car promptly gets into the state of traveling at the uniform speed, but the speed of lift car is very little at this moment, so get in the process of leveling zone at lift car, customer requirement is waited for great amount of time.
But variable resistance described in the present embodiment 9 has determined said synchronous motor 1 to flow into the size of the electric current of said short unit 10 with electro-motive force jointly.Thereby also determined synchronous motor 1 in-to-in correspondingly to generate the size of opposing torque electric current further; Thereby regulate the electro-motive force and the counter electromotive force of synchronous motor 1 through the electric current of regulating said opposing torque electric current and the said short unit 10 of said synchronous motor 1 inflow; Thereby regulate opposing torque and torque further; So regulated the time that torque and opposing torque get into state of equilibrium, thereby velocity magnitude when having regulated said lift car and traveling at the uniform speed.
Can also adopt other current regulating circuit to control the electric current that synchronous motor 1 flows into said short unit 10 in addition in the present embodiment.Though more than described the specific embodiment of the present invention, it will be understood by those of skill in the art that these only are casehistorys, protection scope of the present invention is limited appended claims.Those skilled in the art can make numerous variations or modification to these embodiments under the prerequisite that does not deviate from principle of the present invention and essence, but these changes and modification all fall into protection scope of the present invention.
