Embodiment
The embodiment of the present invention is elaborated below in conjunction with accompanying drawing.
Of the invention to include rotor, stator and controller as shown in Fig. 1-3, rotor is made up of left half rotor, right half rotor,
Left half rotor 5 is connected through the first attachment screw 4 with the traction sheave 3 of elevator, and right half rotor 8 is through the second attachment screw 9 and left half
Rotor 5 is connected, and constitutes the structure that left half rotor and right half rotor are rotated together with traction sheave；Left half rotor and right half rotor it
Between annular groove built with stator support 6, coil 7 is evenly equipped with stator support 6, stator structure is constituted；The lower section of stator support 6 is filled
There are terminal box 11 and velocity sensor 10, stator support 6 is fixed on stator base 12, and velocity sensor 10 connects controller 16,
The power end of controller 16 connects power supply through breaker 17, start stop switch 15, loudspeaker 18, power supply indicator 19, status indicator lamp 20,
Nixie display 21 is respectively connected with controller, and controller 16 is connected by terminal box 11 with coil 7, constitutes electrical control knot
Structure.
In order to ensure using effect and easy to use, described stator support 6 is in be set in hollow circular cavity, cavity
Have and coil has been installed around in uniform winding bore, winding bore, have 1-2mm's between stator support and left half rotor 5, right half rotor 8
Gap, it is ensured that effective rotation of rotor.
Embodiment described above is used for illustrating the present invention, rather than limits the invention, all at this
In the design philosophy and scope of the claims of invention, any modification or change are made to the present invention, its essence and this hair
Bright technical scheme is identical, is regarded as protection scope of the present invention.
The present invention is wound with traction electric in use, the traction sheave 3 of left half rotor 5 and elevator is fixed together on traction sheave 3
The steel wire rope 13 of terraced car 14, traction sheave 3 is in the rotating shaft of traction machine 2, and traction machine 2 is fixed on the base of traction machine in computer room
On 1, controller and stator base 12 are installed in elevator(lift) machine room, and controller works independently, and does not have with elevator control system itself
There is the contact of electric signal, do not controlled by elevator own control systems.
When elevator is normally run, traction machine 2 is fixed on base of traction machine 1, and traction machine 2 passes through traction sheave 3 and steel wire rope
13 drive cars 14 move up and down, and are connected by left half rotor attachment screw 4 with traction sheave 3 due to left half rotor 5, right half rotor
8 are connected by right half rotor attachment screw 9 with left half rotor 5, so when elevator is normally run, left half rotor 5 and right half rotor 8
As traction sheave 3 is rotated together.
Its working condition is specifically provided by Fig. 4, closes the switch of breaker 17, and controller 16 switches on power, power supply instruction
Lamp 19 is bright, opens start stop switch 15, retarder is in running order, and the Chang Liang of status indicator lamp 20, velocity sensor 10 is real-time
Controller 16 is given by the tach signal of traction sheave, controller 16 is by calculating and including the real-time speed of car aobvious in number
Show on device 21.
When lift car 14 exceeds the speed limit, controller 16 receives the overspeed signal that velocity sensor 10 is detected, calculates car and 14 surpasses
The percentage of speed, then exports the electric current proportional to hypervelocity percentage, while the controlling loudspeaker 18 of controller 16 is reported to coil 7
Alert, status indicator lamp 20 flashes.It is passed through after electric current, can be formed between coil 7 and left half rotor 5, right half rotor 8 in coil 7
Induced electromotive force and sense are produced in magnetic field, left half rotor 5 and the right cutting magnetic line of half rotor 8, left half rotor 5 and right half rotor 8
Induced current, left half rotor 5 and the right cutting magnetic line of half rotor 8, so that electromagnetic force is produced, the direction of the electromagnetic force and left half rotor
5 and right half rotor 8 direction of rotation on the contrary, the electromagnetic torque produced using the electromagnetic force reduces left half rotor 5 and right half way around
The speed of son 8, because left half rotor 5, right half rotor 8 are connected with traction sheave 3, the reduction of left half rotor 5 and the right speed of half rotor 8
The speed of car 14 can be reduced.
When the speed of service of car 14 is reduced within normal speed, controller 16 receives the letter of velocity sensor 10
Number, controller 16 stops to the output current of coil 7, and electromagnetic torque is disappeared, and elevator is normally run, while controlling loudspeaker 18 stops
Sounding, status indicator lamp 20 are changed into Chang Liang.
After start stop switch 15 is closed, power supply indicator 19 is bright, loudspeaker 18 stop sounding, status indicator lamp 20 go out,
Nixie display 21 goes out, the no current of coil 7, when pulling lower breaker 17, whole retarder control system dead electricity, electromagnetic retarder
Do not work, but do not influence the normal operation of elevator.
The tach signal of traction sheave is given controller 16 by velocity sensor 10 in real time, and controller 16 calculates and judges sedan-chair
Whether railway carriage or compartment exceeds the speed limit, if do not exceeded the speed limit, and controller 16 is to the no output current of coil 7, if controller 16 judges car speeding,
Controller 16 exports the electric current proportional to hypervelocity percentage to coil 7.
From the foregoing, the present invention is mounted on elevator traction sheave, there is no electric signal with elevator own control systems
Contact.When elevator is in the normal speed of service, the device is not worked, and the normal operation of elevator is not influenceed；When the fortune of elevator
When scanning frequency degree exceedes the speed allowed, the device produces the electromagnetic torque opposite with elevator traffic direction to elevator traction sheave, with
Reduce lift car the speed of service, it is to avoid elevator overspeed and cause the accident.The elevator electromagnetic retarder may be mounted at
On the cargo lift of the man lift or factory of residence or office building, it can avoid because of apparatus for controlling elevator entanglement, manual operation mistake
The generation for the elevator overspeed phenomenon that mistake etc. is caused, improves the safety coefficient of elevator, compared with prior art, with following significant
Beneficial effect：
The present invention can be out of hand in elevator and produces opposing torque when exceeding the speed limit, and is slowed down the speed of service of elevator, is prevented
Because apparatus for controlling elevator failure and caused by elevator overrun, rush to summit, the generation of the peril such as pier bottom, improve the safety of elevator
Property, through site test and application, car is fully loaded with because out of control from when falling for 15 layers, and speed when car reaches 1 layer can be reduced to certainly
By more than the 1/10 of speed of falling, the impulsive force at car pier bottom greatly reduces, thus be effectively reduced injury that accident causes or
More than 10 times of loss, at least mitigation and injury；In an experiment, the low layer floor elevator for less than 10 layers, the present invention with
The buffer of elevator bottom coordinates, and elevator is out of control almost not to cause big loss and injury when falling, and effect is very good.Effectively
For the elevator of high residential building, business building or industrial premises, with simple in construction, reliability it is high, do not controlled by elevator itself
Systematic influence, do not influence elevator normal operation advantage, with good application value, there is significant economic and society's effect
Benefit.
