Brake equipment main body 9 has: first brake disc (swivel) 15 and second brake disc (swivel) 16, and it can rotate with motor reel 12 one; First brake body 17 and second brake body 18, its can with first brake disc 15 and second brake disc 16 in any one braking position that contacts at least and the releasing position left from first brake disc 15 and second brake disc 16 between be shifted; A plurality of springs (force body) 19, it carries out the application of force to first brake body 17 and second brake body 18 to braking position; And electromagnet 20, the application of force that it is used to overcome each spring 19 makes first brake body 17 and second brake body 18 be shifted to the releasing position.
Herein, Fig. 3 is the constructional drawing of the electromagnet 20 of schematically illustrated Fig. 2.Among the figure, electromagnet 20 has: columned secured core 28 (Fig. 2), and it is fixed on the electrical motor 11; And a pair of first magnet coil 29 and a pair of second magnet coil 30, it produces the electromagnetic attraction that attracts armature 22 by switching on.
Provide electric power from first power supply 31 to each first magnet coil 29, provide electric power to each magnet coil 30 from second source 32.And, utilize first current probe (CT), 33 instrumentations to offer the respectively energising amount of first magnet coil 29 from first power supply 31, utilize second current probe (CT), 34 instrumentations to offer the energising amount of each second magnet coil 30 from second source 32.In addition, be electrically connected with the operation controller (not shown) of control elevator running on the braking force control system 10.

Braking force control system 10 is to the voltage instruction of first power supply, 31 outputs to first magnet coil 29, to the voltage instruction of second source 32 outputs to second magnet coil 30.First power supply 31 to first magnet coil 29 apply with to the cooresponding voltage of the voltage instruction value of first magnet coil 29, second source 32 to second magnet coil 30 apply with to the cooresponding voltage of the voltage instruction value of second magnet coil 30.That is, braking force control system 10 outputs are to first magnet coil 29 and second magnet coil 30 voltage instruction separately, thereby control is to the energising of first magnet coil 29 and second magnet coil 30.
When making 9 actions of brake equipment main body, 10 pairs first magnet coils 29 of braking force control system and second magnet coil 30 carry out mutually different energising control.
That is, when making 9 actions of brake equipment main body, braking force control system 10 controls offer the energising amount of first magnet coil 29 and offer the energising amount of second magnet coil 30, so that electromagnetic attraction produces overbalance.
In this embodiment, when making 9 actions of brake equipment main body, 10 pairs first magnet coils 29 of braking force control system and second magnet coil 30 carry out mutually different energising control, so that the application of force by each spring 19 and from the electromagnetic attraction that first magnet coil 29 and second magnet coil 30 produce makes 17 deflections of first brake body.
Fig. 4 is the schematic configuration diagram of the brake equipment main body 9 when first brake body 17 of Fig. 2 and second brake body 18 being shown being positioned at braking position.As shown in the figure, when stopping to first magnet coil 29 and 30 energisings of second magnet coil, by the application of force of each spring 19, first brake body 17, first brake disc 15, second brake body 18 and second brake disc 16 are pressed against on the cover plate 13 with the state at the axial overlap of motor reel 12.At this moment, slide unit 23,25 contacts with first brake disc 15, and slide unit 26,27 contacts with second brake disc 16, and the rotation of first brake disc 15 and second brake disc 16 is braked.
Fig. 5 is the schematic configuration diagram of the brake equipment main body 9 when first brake body of Fig. 4 and second brake body being shown being positioned at the releasing position.As shown in the figure, when first magnet coil 29 and 30 energisings of second magnet coil, first brake body 17 is attracted by electromagnet 20, to the direction displacement away from cover plate 13.Thus, releasing is to the braking of first brake disc 15 and second brake disc 16.
Then, action is described.Fig. 6 is the diagram of curves of action that is used for the brake equipment 8 of instruction diagram 3, Fig. 6 (a) is that braking that operation controller is shown is released order and the diagram of curves of the relation between the time, Fig. 6 (b) is the diagram of curves that illustrates the voltage instruction of first magnet coil 29 and the relation between the time, Fig. 6 (c) is the diagram of curves that illustrates the voltage instruction of second magnet coil 30 and the relation between the time, Fig. 6 (d) is the diagram of curves that illustrates to the energising amount and the relation between the time of first magnet coil 29, and Fig. 6 (e) is the diagram of curves that illustrates to the energising amount and the relation between the time of second magnet coil 30.
As shown in the figure, when car 2 stops at floor (T0 constantly), stop to brake release order (Fig. 6 (a)) to braking force control system 10 outputs from operation controller.At this moment, stop to provide electric power (Fig. 6 (b), Fig. 6 (c)), utilize the application of force of each spring 19, make first brake body 17 and second brake body 18 be displaced to braking position (Fig. 4) to first magnet coil 29 and second magnet coil 30.Thus, the rotation of first brake disc 15 and second brake disc 16 is braked, and the stop position of car 2 is maintained.
When car 2 begins (T1 constantly) when mobile, from operation controller to braking force control system 10 output brakings release order (Fig. 6 (a)).Thus, export first magnet coil 29 and second magnet coil 30 voltage instruction (Fig. 6 (b), Fig. 6 (c)) separately to first power supply 31 and second source 32 simultaneously from braking force control system 10, provide electric power first magnet coil 29 and second magnet coil 30.Afterwards, when the energising amount that offers first magnet coil 29 and second magnet coil 30 increases, during due in T2 (Fig. 6 (d), Fig. 6 (e)), first brake body 17 and second brake body 18 are removed the braking to first brake disc 15 and second brake disc 16 to releasing position displacement (Fig. 5).
Then, when car 2 moves, when car 2 stops at other floor once more, stop to brake release order (Fig. 6 (a)) from operation controller output.Thus, at first only stop from the output (Fig. 6 (b)) of the voltage instruction of braking force control system 10 first magnet coil 29.Afterwards, as T delay time, when becoming moment T4, stop output (Fig. 6 (c)) to second magnet coil 30.That is, utilize braking force control system 10 controls, make that the period that stops to 29 energisings of first magnet coil is different with the period that stops to 30 energisings of second magnet coil first magnet coil 29 and second magnet coil 30 energising separately.Thus, after the energising amount that offers first magnet coil 29 began T fall time, the energising amount that offers second magnet coil 30 began descend (Fig. 6 (d), Fig. 6 (e)).
Then, first magnet coil 29 and the second magnet coil 30 energising amount separately that offers continues to reduce, when being moment T5 (Fig. 6 (d), Fig. 6 (e)), first brake body 17 only has the part that attracted by first magnet coil 29 to leave electromagnet 20 by the application of force of each spring 19 under the state that is attracted by second magnet coil 30.That is, the electromagnetic attraction of first magnet coil 29 that the energising amount begins earlier to descend is less than the electromagnetic attraction of second magnet coil 30, so left electromagnet 20 earlier by the part of first brake body 17 of first magnet coil, 29 attractions.Thus, first brake body, 17 deflections.
Herein, Fig. 7 is the schematic configuration diagram of the brake equipment main body 9 when first brake body, 17 deflections of Fig. 5 are shown.As shown in the figure, when 17 deflections of first brake body, the part that the deflection of first brake body 17 is big more, the interval between first brake body 17 and first brake disc 15 is more little.That is, the compartment between first brake body 17 and the brake disc 15 reduces.
Afterwards, when the energising amount that offers first magnet coil 29 and second magnet coil 30 further descends and near 0 the time, the application of force of each spring 19 surpasses the electromagnetic attraction of second magnet coil 30, first brake body 17 and second brake body 18 are shifted to braking position.That is, the state that reduces since the compartment between first brake body 17 and first brake disc 15 is shifted to the braking position of first brake body 17, and first brake body 17 and second brake body 18 are displaced to braking position.Thus, the rotation of first brake disc 15 and second brake disc 16 is braked.
In such brake device for elevator 8, when making 17 displacements of first brake body, 10 pairs first magnet coils 29 of braking force control system and second magnet coil 30 carry out mutually different energising control, so can first magnet coil 29 and second magnet coil 30 electromagnetic attraction separately when making 17 displacements of first brake body be set at mutually different intensity.Thus, can first brake body 17 partly be left after the electromagnet 20, the 17 whole beginnings of first brake body are shifted to braking position by the application of force of each spring 19.Therefore, the speed of first brake body 17 in the time of can reducing to arrive braking position, the impulsive sound that produces in the time of can reducing the braking maneuver of brake equipment main body 9.And, need not to be used to absorb the padded coaming of impact, so can also reduce manufacturing cost.
And, energising control based on braking force control system 10 makes that the period that stops to first magnet coil 29 and 30 energisings of second magnet coil is different, so can easily the electromagnetic attraction of first magnet coil 29 and the electromagnetic attraction of second magnet coil 30 be set at different intensity, the impulsive sound that produces in the time of can reducing the braking maneuver of brake equipment main body 9.
And, when first brake body 17 from the releasing position when braking position is shifted, the application of force of electromagnetic attraction and each spring 19 by first magnet coil 29 and second magnet coil 30, make 17 deflections of first brake body, so the impulsive sound that produces in the time of can reducing the braking maneuver of brake equipment main body 9, and, can make the distortion left-right symmetric of first brake body 17, therefore, can carry out more stable braking maneuver.
In addition, in embodiment 1, by making the period that stops to first magnet coil 29 and second magnet coil 30 are switched on different, thereby when the braking maneuver of brake equipment main body 9, make first magnet coil 29 and second magnet coil 30 produce the mutually different electromagnetic attraction of intensity respectively, but also can make from beginning to stop different to the time that becomes 0 to first magnet coil 29 and second magnet coil 30 voltage instruction separately, thereby when the braking maneuver of brake equipment main body 9, make first magnet coil 29 and second magnet coil 30 produce the mutually different electromagnetic attraction of intensity respectively.
That is, Fig. 8 is the diagram of curves that is used to illustrate the brake equipment action of embodiment of the present invention 2.And, Fig. 8 (a) is that braking that operation controller is shown is released order and the diagram of curves of the relation between the time, Fig. 8 (b) is the diagram of curves that illustrates the voltage instruction of first magnet coil 29 and the relation between the time, Fig. 8 (c) is the diagram of curves that illustrates the voltage instruction of second magnet coil 30 and the relation between the time, Fig. 8 (d) is the diagram of curves that illustrates the energising amount and the relation between the time of first magnet coil 29, and Fig. 8 (e) is the diagram of curves that illustrates the energising amount and the relation between the time of second magnet coil 30.
As shown in the figure, braking force control system 10 begins to stop to first magnet coil 29 and second magnet coil 30 voltage instruction (Fig. 8 (b), Fig. 8 (c)) separately at moment T3 simultaneously.And, moment became 0 after braking force control system 10 will be controlled to the voltage instruction of first magnet coil 29 and begin to stop voltage instruction, will be controlled to the voltage instruction of second magnet coil 30 to begin to stop to descend continuously in certain proportion behind the voltage instruction and become 0 after having passed through the schedule time.That is, braking force control system 10 control is to first magnet coil 29 and second magnet coil 30 voltage instruction separately, make begin to stop behind the voltage instruction different to the time that becomes till 0.Other structure is identical with embodiment 1.
Then, action is described.The release movement of brake equipment main body 9, promptly first brake body 17 is identical with embodiment 1 from the action of braking position when the releasing position is shifted with second brake body 18.
When stopping output, operation controller brakes release order (Fig. 8 (a)), and brake equipment main body 9 is when carrying out braking maneuver, by the control of braking force control system 10, begin simultaneously to stop to export to first magnet coil 29 and second magnet coil 30 voltage instruction separately at moment T3.Afterwards,, voltage instruction moment of first magnet coil 29 is become 0 (Fig. 8 (b)), the voltage instruction of second magnet coil 30 is descended continuously and become 0 (Fig. 8 (c)) when having passed through the schedule time by the control of braking force control system 10.
Thus, after having passed through moment T3, the energising quantitative change that offers first magnet coil 29 and second magnet coil 30 is mutually different amount (Fig. 8 (d), Fig. 8 (e)), with embodiment 1 first brake body, 17 deflections similarly.Action afterwards is identical with embodiment 1.
In such brake device for elevator, when the braking maneuver of brake equipment main body 9, control by braking force control system 10, make from beginning to stop different to the time that becomes 0 to first magnet coil 29 and second magnet coil 30 voltage instruction separately, so with embodiment 1 first brake body 17 is partly left after the electromagnet 20, the 17 whole beginnings of first brake body are shifted to braking position.Therefore, the impulsive sound that produces in the time of can reducing the braking maneuver of brake equipment main body 9.
In addition, in embodiment 2, when the braking maneuver of brake equipment main body 9, the voltage that second magnet coil 30 is applied is descended continuously with certain proportion, but the voltage instantaneous that second magnet coil 30 is applied is dropped to after the predefined setting value, descend continuously with certain proportion again.
That is, Fig. 9 is the diagram of curves of action that is used to illustrate the brake equipment of embodiment of the present invention 3.And, Fig. 9 (a) is that braking that operation controller is shown is released order and the diagram of curves of the relation between the time, Fig. 9 (b) is the diagram of curves that illustrates the voltage instruction of first magnet coil 29 and the relation between the time, Fig. 9 (c) is the diagram of curves that illustrates the voltage instruction of second magnet coil 30 and the relation between the time, Fig. 9 (d) is the diagram of curves that illustrates the energising amount and the relation between the time of first magnet coil 29, and Fig. 9 (e) is the diagram of curves that illustrates the energising amount and the relation between the time of second magnet coil 30.
As shown in the figure, braking force control system 10 begins to stop to first magnet coil 29 and second magnet coil 30 voltage instruction (Fig. 9 (b), Fig. 9 (c)) separately at moment T3 simultaneously.And, moment became 0 after braking force control system 10 will be controlled to the voltage instruction of first magnet coil 29 and begin to stop voltage instruction, to be controlled to the voltage instruction of second magnet coil 30 begin to stop voltage instruction after moment drop to predefined setting value, descend continuously with certain proportion then, when having passed through the schedule time, become 0.Setting value is set in maxim (predetermined value) and the value between 0 to the voltage instruction of second magnet coil 30.Other structure is identical with embodiment 1.
Then, action is described.The release movement of brake equipment main body 9, promptly first brake body 17 is identical with embodiment 1 from the action of braking position when the releasing position is shifted with second brake body 18.
When stopping output, operation controller brakes release order (Fig. 9 (a)), and brake equipment main body 9 is when carrying out braking maneuver, by the control of braking force control system 10, begin simultaneously to stop to first magnet coil 29 and second magnet coil 30 voltage instruction separately at moment T3.Afterwards, by the control of braking force control system 10, voltage instruction moment of first magnet coil 29 is become 0 (Fig. 9 (b)).With respect to this, voltage instruction moment of second magnet coil 30 is dropped to after the setting value, descend continuously with certain proportion, when having passed through the schedule time, become 0 (Fig. 8 (c)).
Thus, after having passed through moment T3, the energising amount that offers first magnet coil 29 and second magnet coil 30 becomes mutually different amount (Fig. 9 (d), Fig. 9 (e)), with embodiment 1 first brake body, 17 deflections similarly.Action afterwards is identical with embodiment 1.
Even in such brake device for elevator, when the braking maneuver of brake equipment main body 9, control by braking force control system 10, make from beginning to stop first magnet coil 29 and second magnet coil 30 voltage instruction separately different to the time that becomes 0, so the impulsive sound that produces can reduce the braking maneuver of brake equipment main body 9 in the same manner with embodiment 2 time.And, when the braking maneuver of brake equipment main body 9, voltage instruction moment of second magnet coil 30 is dropped to after the setting value, descend continuously with certain proportion again, so can make voltage instruction moment drop to the minimum that first brake body 17 can be remained on the voltage instruction of braking position, can shorten the opening time of brake equipment main body 9 to second magnet coil 30.
In addition, in embodiment 1, make the period that stops to first magnet coil 29 and second magnet coil 30 are switched on different, impulsive sound when reducing the braking maneuver of brake equipment main body 9, but also can be different to the period of first magnet coil 29 and 30 energisings of second magnet coil by making beginning, thereby when the release movement of brake equipment main body 9, also realize the reduction of impulsive sound.
That is, Figure 10 is the diagram of curves of action that is used to illustrate the brake equipment of embodiment of the present invention 4.And, Figure 10 (a) is that braking that operation controller is shown is released order and the diagram of curves of the relation between the time, Figure 10 (b) is the diagram of curves that illustrates the voltage instruction of first magnet coil 29 and the relation between the time, Figure 10 (c) is the diagram of curves that illustrates the voltage instruction of second magnet coil 30 and the relation between the time, Figure 10 (d) is the diagram of curves that illustrates the energising amount and the relation between the time of first magnet coil 29, and Figure 10 (e) is the diagram of curves that illustrates the energising amount and the relation between the time of second magnet coil 30.
