Detailed description of the invention
Hereinafter, will by example, with reference, the present invention will be described in more detail, in the accompanying drawings:
Fig. 1 shows lift facility；With
Fig. 2 shows the methods of the lift facility for test chart 1.
Specific embodiment
Fig. 1 shows the lift facility 1 with elevator 2, and elevator 2 includes pulley 9 and driving unit 3, driving unit 3
Such as electric notor, the lift car 4 being arranged in driving lift well 5.Fig. 1 is simplified in an illustrative manner, to show driving
Unit 3 is directly connected to the pulley 9 (or multiple pulleys) of elevator 2 by axis 6, and rope 7 (or multiple ropes) prolongs around pulley
It stretches, for moving lift car 4 and counterweight 8 in the elevator shaft.However, instead of driving unit 3 is directly connected to by axis 6
To pulley 9, gear can be set between driving unit and pulley.
Lift facility 1 is additionally provided with control device 10, controls the operation of elevator 2.For example, control device can use circuit
Or the combination of circuit and computer program is realized.In addition control device 10 controls the first brake 11 and second brake 12,
First brake 11 and second brake 12 are for example arranged to brake axle 6, to stop lift car 4 and to remain in elevator
It is static in vertical shaft 5.However, it is possible to use the other kinds of brake in addition to the elevator brake shown in, in this feelings
Under condition, brake can be different from another part shown in Fig. 1 positioned at lift facility.
Lift facility 1 is equipped with electromechanical lift mechanical brake 11 and 12 and is used as safety device, via the rotation of elevator
Axis 6 applies brake force to hauling block 9, to brake the movement of elevator, thus the movement of elevator brake carriage 4.Usually have two
A individual brake, as shown in the figure.The size of brake 11 and 12 must determine to make to have 125% load (25% overload)
Lift car stop and remain stationary in lift well 5.In addition, brake 11 and 12 is also used for rescue situations, and also
For emergency braking situation, to stop lift car 4 when operating trouble occurs, such as under the overspeed situation of lift car.
In addition, they are for protecting elevator passenger to move in stop from unexpected carriage, and to need to enter inside lift well 5
Maintenance personal provide safety operating environment.It is therefore necessary to ensure that brake is correctly run.
In the example shown, control device 10 is configured as testing the during the normal operating operation of lift car 4
The operation of at least one of one brake 11 and second brake 12.In this case, " normal " operation operation refers to
Lift car can be used for needing the case where advancing to the revenue passenger of another floor 14 from a floor 13 of building.Cause
This, can test while lift facility is in normal manipulation mode in the case where being loaded with passenger, and do not need
Set test pattern for lift facility, the fact that test pattern is for example following: maintenance personal is in erecting bed and passes through
Lift facility works, and needs temporarily to control lift facility via specific CE/operator panel 15, so as to test mould
Formula drives lift car.
In order to test brake during normal operating is run, control device 10 is in lift car 4 due to single from driving
The adjusting of the power F of member 3 and slow-down and while reaching the door 16 at the floor 14 in lift well 5 only triggers at least first
A brake in brake 11 and second brake 12 is to be braked.In this stage, lift car 4 starts to open electricity
The door and stop door 16 of terraced carriage, to discharge passenger from lift car.
Hereinafter, as an example, will assume that specifically the first brake 11 is tested.However, in practice, braking
Device preferably continuously takes turns current test during different elevator operations at predetermined intervals, so that inspecting periodically each brake
Situation.
In this example, once the first brake 11 (being tested) is triggered brake and for the first system
The enough time that dynamic device is engaged has already passed through, then control device 10 reduces the power that lift car 4 is supplied to from driving unit 3
F.The reduction of power F can be realized by reducing the torque T of driving unit 3.
It is required that be, if what the first brake 11 was ordered into, individually it can make lift car 4 in lift well 5
It remain stationary, then driving unit 3 no longer provides any power to lift car via rope 7.Therefore, when power F reduces, control
Device starts to monitor the movement of lift car 4.For example, can be fast by monitoring (rotation) of driving unit 3 (such as electric notor)
Degree is to realize the monitoring.In the case where control device 10 detects that lift car 4 moves, it triggers the finger of failure brake
Show.At this stage, control device 10 is also using the triggering braking of second brake 12, and also increases and be supplied to from driving unit 3
The power F of lift car 4, to stop the movement of lift car as early as possible.
Once triggering the instruction of failure brake, control device 10 just stores in memory to be surveyed about failure brake
The information of examination.Control device can also send remote service center for the information about failure brake via long-range connection
(memory can be located at the remote service center).Finally, once triggering the failure of predetermined quantity for identical brake
Test, then control device can prevent from carrying out further normal operating using related lift car 4, pre- until receiving
Fixed control command.It has arrived at the position and the maintenance personal that is suitably serviced to failure brake can be via
Such as predetermined control order is passed to control device 10 by CE/operator panel 15.It prevents pre- needed for lift car further operating
The fault test of fixed number amount can change as the case may be.A kind of alternative solution is, if touched in follow-on test three times
The indicating fault for sending out brake identical, then prevent the further operating of lift car.
In one embodiment, in the nonvolatile memory about the information storage for the further operating for preventing elevator,
And the information based on storage in the nonvolatile memory prevents the further operating of elevator.
However, if control device 10 does not detect any movement of lift car 4, and the first brake being triggered
It brakes and driving unit 3 no longer provides any power to lift car by rope 7, then control device determines tested first
Brake is in good working order.Test result is stored preferably in memory.Furthermore it is possible to terminate to test, so that
It continues through two brakes to be braked, until the most Zhongdao time for newly testing one of brake.
Fig. 2 shows the methods for example for the lift facility of test chart 1.
Line 17 in Fig. 2 shows the measurement motor speed of driving unit 3 (such as electric notor), and it is single that line 18 shows driving
The torque that member 3 is provided at different moments (T0-T4).The power F for being supplied to lift car 4 from driving unit 3 depends on torque.Separately
Outside, Fig. 2 shows the state of the first brake 11 by line 19 and shows the state of second brake 12 by line 20.
The time for testing the first brake 11 has been arrived when the control device 10 of lift facility 1 determines, and has been set by elevator
Standby user interface 21 starts normal behaviour at the door 16 of lift well 5 or from the internal receipt of lift car 4 to elevator-calling
The lift car of work is run.In this stage, elevator by means of normal driving unit torque with normal motor speed 17 from
First floor 13 movement, as shown in the left side in Fig. 2.In this stage, the first brake 11 (line 19) and second brake 12
(line 20) is maintained at unengaged position, they are all not braking herein.
In moment T0, lift car is close to the door region of the stop at floor 14.In this stage, driving unit speed (line
17) reduce with torque (line 18).In moment T1, elevator has reached the correct level of floor 14, and thus the movement of elevator is with drive
Moving cell stops, so that driving unit speed (line 17) reaches zero.Start the door 16 in the door and lift well 5 of lift car
It opens.In addition, only triggering the braking of the first brake 11.
In practice, be triggered from the first brake 11 with that moment for being braked until the brake is at the moment
There are significant delay D1 when the practical braking of T2.One of this delay the reason is that the electromagnet in dynamo-electric brake induction energy
Amount.When brake is triggered to be braked, interrupts first and the electric current of coil is supplied.Certain value is reduced in coil current
Rear brake engagement below.Due to the high inductance of restraining coil, according to brake type, application/electric current of brake subtracts
It is small to need several hundred milliseconds (such as 300ms).
Once delay D1 has already passed through and assume that the first brake actual engagement and brake that then control device 10 subtracts
The small power F that lift car 4 is supplied to from driving unit 3.This can be regarded as the driving unit 3 since moment T2 in Fig. 2
The oblique deascension of torque (line 18).Start the movement of monitoring lift car in this stage.
In the example shown, the speed (line 17) for showing driving unit 3 increases since moment T2.Therefore, it controls
Device 10 detects the movement of lift car 4 and triggers the instruction of failure brake.
When detecting the failure of the first brake 11, control device passes through second brake 12 immediately to be triggered in moment T3
Braking.In addition, driving unit torque (line 18) increases, so that increasing from the power F that driving unit 3 is supplied to lift car.Pass through
This mode, lift car are remain stationary.After postponing D2, second brake 12 engages and starts again at drive from moment T4
The oblique deascension of the torque (line 18) of moving cell 3.
It should be understood that above description and attached drawing are merely to illustrate the present invention.It will be apparent to one skilled in the art that
Without departing from the scope of the invention, thus it is possible to vary and the modification present invention.
