Definitions
- the present invention relates to a brake device for an elevator in which noise during braking or braking is reduced.
- Elevator brakes especially brakes for hoisting machines, are designed so that the electromagnetic stone is deenergized and the brake lining is pressed against the brake wheel by a brake spring to brake by friction.
- the magnet When releasing the brake, the magnet is energized to suck the movable iron core, and the brake spring is applied to the brake spring to separate the brake shoe from the brake wheel to release the brake.
- the electromagnet has the characteristic that the attractive force increases as the distance from the movable iron core decreases. For this reason, when releasing the brake, the movable iron core is attracted to the electromagnet and a collision sound is generated.
- the brake lining presses the brake lining against the brake wheel, generating a sound.
- the noise generated when the brakes were actuated and when the brakes were released was transmitted to the inside of the car and the landing, causing a noise problem. Sound can be reduced by reducing the distance between the fixed core and the movable core of the electromagnet.However, due to the shortening, when the brake is released, the brake lining and the brake wheel do not separate sufficiently, and a part of them slides into contact with each other. A sliding noise is generated as the vehicle travels. For this reason, it was necessary to improve the processing accuracy, and there was a problem that productivity was low.
- Japanese Patent Laid-Open Publication No. Hei 8-73143 discloses a sound absorbing plate attached to a gap between a fixed iron core and a movable iron core of an electromagnet.
- a structure has been disclosed in which a movable iron core is caused to collide with the armature to reduce the impact sound of the electromagnet when the brake is released.
- Japanese Patent Application Laid-Open No. H08-731143 discloses that the reaction force of a brake spring that urges a movable iron cover (movable iron core) in a direction to separate it from a magnet frame (fixed iron core) is fixed to the fixed iron core.
- control is performed so that the attraction force of the electromagnet is greater than the reaction force of the brake spring by a predetermined value. In this way, noise during opening can be reduced.
- the attraction force of the electromagnet is controlled so as to be smaller than the reaction force of the brake spring by a predetermined value to reduce the noise at the time of actuation. .
- the present invention provides a rotating body in which a retractable brake shoe is advanced by a brake spring.
- the brake device of an elevator equipped with an electromagnet that pulls the movable iron core and attracts the movable iron core to retract the brake shoe against the brake spring to release the braking, and the electromagnet accompanying the decrease in the gap between the electromagnet and the movable iron core
- the present invention relates to a case in which the braking of a brake device provided with a biasing elastic body which resists the suction force with a reaction force having an increase rate larger than the suction force increase rate is released. At first, the exciting current is gradually increased, and the brake is retracted initially against the reaction force of the brake spring alone.
- the movable iron core is gradually attracted as the exciting current is gradually increased, and the brake shoe is retracted while balancing the total reaction force of the elastic body and the brake spring that have been applied in the middle.
- the excitation current is controlled so that the movable iron core is attracted by the attraction force larger than the total reaction force and the brake retracts to release braking. Therefore, when braking is released, the electromagnet gradually attracts and attracts the movable core as the exciting current gradually increases, while balancing the total reaction force of the energized elastic body and the brake spring from the middle. Also, it is possible to reduce the sound of collision between the electromagnet and the movable iron core.
- the present invention relates to a case in which the rotating body is braked by the brake device described in the above item 1, and the movable iron core is sucked with a suction force larger than a total reaction force of the brake spring and the biasing elastic body.
- the excitation current is gradually reduced from the state where braking is released. From the attracted state to the point of application of the elastic body, the movable iron core is gradually separated from the movable core as the exciting current gradually decreases while balancing the total reaction force, and the brake shoe is advanced.
- the brake spring is advanced by the reaction force of the brake spring alone to control the rotating body.
- the movable iron core gradually separates from the attracted state to the energized point of the elastic body while balancing the total reaction force, and the brake spring accelerates and advances due to the reaction force of the brake spring alone. Since the movement is performed after the point of application, the travel distance of the brake shoe, which is a cause of noise generation, is substantially reduced, and the sound of collision with the rotating body can be reduced.
- the exciting current gradually decreases, but the electromagnet continues to be energized.Therefore, the reaction force of the brake spring is reduced by the attraction force of the electromagnet, and the collision noise is reduced. It can be reduced. Also, the exciting current eventually becomes 0 value, Since it is pressed by the brake spring, the hoist can be reliably braked irrespective of the elastic body.
- the biasing elastic bodies are juxtaposed and separated from the electromagnet in a direction perpendicular to the moving direction of the movable iron core.
- the biasing elastic body is biased by the brake spring until the brake shoe is completely retracted from the position where the brake of the hoist is released.
- the biasing elastic body is constituted by a coil spring. Therefore, a stable reaction force can be obtained over a long period of time.
- the biasing elastic body is constituted by a rubber column. Therefore, no collision sound is generated when the urging elastic body is energized.
- the present invention further includes an adjusting means for adjusting a position at which the rubber pillar biases the brake spring.
- the biasing elastic body is constituted by a leaf spring.
- the size of the biasing elastic body in the pressing direction may be equivalent to the amount of deflection of the leaf spring, and can be installed even in a narrow space.
- the present invention can change the spring constant by increasing or decreasing the distance from the supporting point of the leaf spring to the point of action.

- the control circuit of the electromagnet 11 shown in FIG. 3 functions as an excitation control means for controlling the exciting current i so that the brake 15 is retracted by closing the brake control contact 23 to release the braking.

- the brake control contact 23 is opened and the coil 13 is deenergized. For this reason, the brake shoe 5 is pushed by the reaction force P 0 by the brake spring 6 via the arm 3, advances and comes into contact with the inner peripheral surface of the brake wheel 1. Therefore, the movable core 10 is at the separation end point g2.
- the brake control contact 23 is closed at time t0.
- the voltage of the input of the amplifier 27 rises with a time constant determined by the capacitor 25 and the resistor 26 as shown in FIG.
- the output of amplifier 27 is connected to the base of transistor 29 via base resistor 28. Applied. Accordingly, the exciting current i of the coil 13 rises from the time t0 and becomes i3 at the time t1, as shown in FIG. Due to the exciting current i 3, the attractive force f 3 of the electromagnet 11 is balanced with the reaction force P 0 of the brake spring 6.
- the attraction force f of the electromagnet 1 1 exceeds the reaction force P 0 of the brake spring 6, the attraction force f increases due to the aging increase of the exciting current i in addition to the increase due to the decrease in the air gap g.
- the movable iron core 10 is rapidly sucked by the difference value with respect to the reaction force. On the way, the movable iron core 10 has extra stroke (if it moves by 5 toward the electromagnet 11 side, the energizing coil spring 14 energizes the brake spring 6 and resists the attractive force of the electromagnet 11 by its total reaction force.
- the energizing coil spring 14 resists the attraction force f with a reaction force having an increasing rate larger than that of the attraction force f of the electromagnet 11 1 due to the decrease in the gap g between the electromagnet 11 and the movable core 10.
- the electromagnet 11 gradually balances the attractive force f with the total reaction force and gradually attracts the movable iron core 10, so that it is possible to reduce the collision noise during the attraction.
- the electromagnet 11 is energized by the exciting current i 6 to attract the movable iron core 10 and release the brake operation. Assuming that the brake control contact 23 is opened at time t 11, the input of the amplifier 27 is discharged with the time constant determined by the capacitor 25 and the resistor 26 as shown in FIG. Descend. Therefore, the exciting current i of the electromagnet 11 drops from time t 11 in FIG. 5 to 15 at time t 12. Due to the exciting current i 5, the attractive force f 5 of the electromagnet 11 is balanced with the total reaction force P 4 of the brake spring 6 and the energizing coil spring 14.
- the attractive force f decreases due to the decrease of the exciting current i with time, in addition to the decrease due to the increase in the gap g, and the attractive force f decreases due to the difference value with the reaction force of the brake spring 6. Then, the movable iron core 10 is separated to the separation end point g2 to brake the brake wheel 1.
- the distance at which the brake wheel 1 is accelerated and advanced to contact the brake wheel 1 with the brake lining 5a is determined by the difference between the attractive force by the exciting current i and the reaction force of the brake spring 6.

- the electromagnet 11 when the braking is released, gradually balances with the total reaction force of the energized energizing coil springs 14 and the brake spring 6 as the exciting current i gradually increases while being halfway. Since the movable iron core 10 is sucked and adsorbed, the collision sound between the electromagnet 11 and the movable iron core 10 can be reduced. Moreover, since the brake spring 6 is initially the reaction force of the brake spring 6 alone, the brake can be reliably released from the brake wheel 1 regardless of the energizing coil springs 14 to release the braking.
- the movable core 10 is gradually separated from the attracted state to the energized point of the energizing coil spring 14 while balancing with the total reaction force, and the movable spring core 10 is separated by the reaction force of the brake spring 6 alone.
- the brake stroke 5 is advanced by the surplus stroke ⁇ after the boosting point g1, so that the acceleration distance of the brake shoe 5, which causes noise, has been substantially reduced, and the brake wheel The collision sound with 1 can be reduced.
- the electromagnet 11 continues to be energized, so that the reaction force of the brake spring 6 is reduced and the collision noise is reduced. Can be reduced.
- the exciting current i finally becomes 0 and the brake shoe 5 is pressed by the brake spring 6, it is possible to reliably brake the hoist regardless of the energizing coil spring 14. it can.
- the energizing coil spring 14 is moved electromagnetically in a direction orthogonal to the moving direction of the movable core 10. Since they are arranged side by side apart from the stones 11, it is not necessary to increase the gap g between the fixed iron core and the movable iron core by providing the energizing coil springs 14, so that the magnetic resistance in the gap g does not increase.
- the energizing coil spring 14 is energized to the brake spring 6 from the position where the brake shoe 15 releases the braking until the brake spring 15 retreats, the electromagnet 11 and the movable core 10 are connected to each other.
- the brake spring can be used both when the brakes 5 come into contact with the brake wheel 1 to brake and when the brakes 5 are separated from the brake wheel 1 to release the braking.
