The 10%～50% of rated current, more preferably 30%.
The invention have the advantage that the present invention can detect traction machine band-type brake power automatically the most up to standard, with stop by
In traction machine band-type brake power not enough and cause slip the security incidents such as car.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings and embodiment the invention will be further described:
Fig. 1 is the structural member figure of the present invention this elevator traction machine band-type brake force checking device；
Wherein: 1-electric life controller, 2-elevator driving frequency converter, 3-encoder, 4-traction machine, 5-brake,
6-lift car, 7-elevator counterweight.
Detailed description of the invention
Fig. 1 is the structure diagram of the present invention this elevator traction machine band-type brake force checking device, and it includes elevator control
Device 1 processed, traction machine 4, the brake 5 being loaded on traction machine 4, lift car 6 and elevator counterweight 7, for
Improving the security of elevator, the quantity of described brake 5 is generally at least two (usually two),
So when, after one of them brake failure, also having other brake operation.
The key improvements of the present embodiment is: this detection device also includes the elevator being connected with described traction machine 4
Drive frequency converter 2 and be loaded on described traction machine 4 and can monitor the encoder 3 whether traction machine rotates,
Described electric life controller 1, elevator drive frequency converter 2 and encoder 3 to be all electrically connected with described electric life controller.
The weight of described elevator counterweight 7 deducts the weight of described lift car 6, the most described elevator car
The weight of the weight ≈ elevator cage of the 50% of railway carriage or compartment 6 nominal load capacity, i.e. elevator counterweight+payload ratings/2 (this
For Lift car type elevator common technology means).
Utilize the present embodiment this elevator traction machine band-type brake force checking device to detect elevator traction machine band-type brake power
Method is as follows:
Idle period that a, some elevator in selected one day run (2:00 AM of such as every day to 3 point,
Certainly, specifically chosen in which, can be manually set period), within a certain period of time (as in half an hour or
In one hour) elevator is not when carrying out summoning operation, and electric life controller 1 automatically turns on detection function.Described
" elevator run idle period ", refer to the offpeak period that this elevator runs under normal circumstances, different
Its operation idle period of elevator also differs, and the purpose done so is not affect people's normally making elevator
With, and it can be avoided that when elevator detects, elevator accident occurs.
After electric life controller 1 automatically turns on detection function, electric life controller 1 controls lift car 6 and stops fortune
OK, and close hall door and summon function.
It is to say, when elevator is within this time period of 2:00 AM to 3, if it exceeds do not have half an hour
Run, then electric life controller 1 automatically turns on detection function, controls lift car 6 out of service (the most first
Control to make again after lift car runs to top layer that it is out of service), and close hall door and summon function.
Elevator accident, before open detection function, best detection lift car is there is during in order to avoid detection
The most whether have people or article, when detect in lift car for blank state time, be then turned on detection function, it
Rear entrance step b.
B, ladder controller 1 are by the brake 5 (referred to herein as first brake 5) on traction machine 4
Unclamping, remaining brake is still within power-off locking state.Because the weight of elevator counterweight 7 deducts described electricity
The weight of ladder car 6, the 50% of the most described lift car 6 nominal load capacity, so now to draging
Draw the up power force value close to traction machine 4 nominal torque of machine 4 applying.Traction machine 4 monitored by encoder 3
No rotation, if monitoring traction machine 4 have rotation, is then directly entered failsafe state, and elevator is out of service.
If monitoring traction machine 4 not rotate, then enter next step.
C, elevator drive frequency converter 2 that traction machine 4 applies the ascending current of a certain size (can be manually set),
Now this elevator drives frequency converter 2 that the ascending current that traction machine 4 applies is generally traction machine 4 rated current
10～50%, optimum is 30%.Encoder 3 monitors whether traction machine 4 rotates, and will monitoring signal feedback
To electric life controller 1, this monitoring result is recorded by electric life controller 1 simultaneously, if monitoring traction machine 4
Having rotation, be then directly entered failsafe state, elevator is out of service.If monitoring traction machine 4 not rotate,
Then enter next step；
D, electric life controller 1 control that brake 5 power-off of unclamping in above-mentioned steps b and locking traction machine
3, then another brake 1 (referred to herein as second brake) controlling traction machine 4 unclamps, and goes forward side by side
Row step b and the detection of step c；
E, as above cycle detection, unclamp the 3rd brake, the 4th brake successively ..., by
One detects, until all having been detected by all brakes 5 on traction machine 4.
Above-mentioned electric life controller 5, elevator drive the electrical structure of frequency converter 2 and encoder 3 to be automation neck
Territory routine techniques, does not repeats them here.The realization of above-mentioned functions, needs to write phase in electric life controller 5
The control program answered.
Certainly, above-described embodiment, only for technology design and the feature of the explanation present invention, its object is to allow people
Will appreciate that present disclosure and implement according to this, can not limit the scope of the invention with this.All
The equivalent transformation done according to the Spirit Essence of main technical schemes of the present invention or modification, all should contain in the present invention
Protection domain within.
