上述のような従来のディスクブレーキ装置では、押圧力の調整が手動でしか行えず、ライニング摩擦係数の変動を考慮すると、バネ押圧力を高めに設定せざる得なくなり、摩擦係数が高い状況では、非常停止時の減速度が大きくなる欠点があった。また、特に機械室レスエレベータの場合、調整するにはエレベータを停止させ、昇降路内に入っての作業となるため、頻繁に調整できない問題があった。   In the conventional disc brake device as described above, the pressing force can only be adjusted manually, and in consideration of the fluctuation of the lining friction coefficient, the spring pressing force has to be set higher, and in a situation where the friction coefficient is high, There was a drawback that the deceleration during emergency stop was large. In particular, in the case of a machine room-less elevator, there is a problem in that adjustment cannot be made frequently because the elevator is stopped and adjusted to enter the hoistway.

この発明は、上記のような課題を解消するためになされたもので、遠隔でバネ押圧力の調整が実施可能なブレーキ装置を得ようとするものである。また、ブレーキトルク調整を制御することで、ブレーキ落下音が小さく、ライニングの摩擦係数が変動しても適正なブレーキトルクを発生するブレーキ装置を得ようとするものである。   The present invention has been made to solve the above-described problems, and an object of the present invention is to obtain a brake device capable of remotely adjusting a spring pressing force. In addition, by controlling the brake torque adjustment, an object is to obtain a brake device that generates an appropriate brake torque even when the brake falling noise is small and the friction coefficient of the lining fluctuates.

In an elevator hoisting brake device for braking, a movable spring seat for adjusting a spring pressing force of the braking spring against the movable iron core, an actuator for moving the movable spring seat forward and backward, and the actuator are controlled. A control device is provided.

実施の形態1.
図1はこの発明の実施の形態1であるエレベータ用巻上機のディスクブレーキ装置の断面図である。キャリパー1は被制動用のディスク2の外周縁が差し込まれる凹溝部3を有し、その凹溝部3内に、一対のブレーキシュー4,4が配設され、このブレーキシュー4,4は、ディスク2をその両面から挟圧して制動する。略門型のキャリパー1の一側面壁には、ロッド21が、他側面壁には電磁石部6のプッシュロッド7がそれぞれ配設され、ブレーキシュー4がロッド21の先端と、プッシュロッド7の先端にそれぞれ取付けられている。ロッド21はキャリパー1の一側面壁に固着され、他方、プッシュロッド7は電磁石部6の可動鉄心8に一体に固着されて、キャリパー1の貫通孔9に遊嵌状に挿通されている。
Embodiment 1 FIG.
1 is a sectional view of a disk brake device for an elevator hoist according to Embodiment 1 of the present invention. The caliper 1 has a concave groove portion 3 into which an outer peripheral edge of a disc 2 to be braked is inserted, and a pair of brake shoes 4, 4 are disposed in the concave groove portion 3. 2 is clamped from both sides to brake. A rod 21 is disposed on one side wall of the substantially caliper-shaped caliper 1, and a push rod 7 of the electromagnet portion 6 is disposed on the other side wall. Installed in each. The rod 21 is fixed to one side wall of the caliper 1. On the other hand, the push rod 7 is fixed integrally to the movable iron core 8 of the electromagnet portion 6 and is inserted into the through hole 9 of the caliper 1 in a loose fit.

電磁石部6は固定鉄心10と円板状の可動鉄心8を有し、固定鉄心10には電磁コイル11が巻設され、固定鉄心10と電磁コイル11はキャリパー1に連結ロッド22を介して固定されて相対的に動かない。制動用バネ23は、固定鉄心10内の収納孔に配置されて、可動鉄心8を矢印E方向へ弾発付勢する。制動用バネ23は図のように、2個設けられているが、1個または3個でも良い。電磁コイル11を付勢(通電)すると、可動鉄心8が吸引されて、矢印Eとは反対方向に移動して、ブレーキシュー4,4がディスク2から遊離し、非制動状態となる。他方電磁コイル11を非付勢(通電を遮断)にすると、可動鉄心8の吸引が解かれ、制動用バネ23のバネ押圧力で可動鉄心8が矢印E方向へ移動して、ブレーキシュー4,4がディスク2を挟圧して制動状態になる。   The electromagnet portion 6 has a fixed iron core 10 and a disk-shaped movable iron core 8, and an electromagnetic coil 11 is wound around the fixed iron core 10, and the fixed iron core 10 and the electromagnetic coil 11 are fixed to the caliper 1 via a connecting rod 22. It does not move relatively. The braking spring 23 is disposed in a storage hole in the fixed iron core 10 and elastically biases the movable iron core 8 in the direction of arrow E. Although two brake springs 23 are provided as shown in the figure, one or three brake springs may be provided. When the electromagnetic coil 11 is energized (energized), the movable iron core 8 is attracted and moved in the direction opposite to the arrow E, and the brake shoes 4 and 4 are released from the disk 2 to be in a non-braking state. On the other hand, when the electromagnetic coil 11 is de-energized (energization is interrupted), the suction of the movable iron core 8 is released, and the movable iron core 8 moves in the direction of arrow E by the spring pressing force of the brake spring 23, and the brake shoe 4, 4 clamps the disk 2 and enters a braking state.

可動バネ座24は制動用バネ23の収納孔をガイドに進退(並進)することができる。この可動バネ座24の押え板25は固定鉄心10に固定されたトルク調整用雄ネジ26に螺進退自在に支承されている。ここで、調整用雄ネジ26と押え板25とはボールネジを用いて支承しても良い。押え板25には、減速機部27を介してサーボモータ(アクチュエータ)28が取付けられている。制御装置29はこのサーボモータ28を制御する。   The movable spring seat 24 can move back and forth (translate) with the accommodation hole of the braking spring 23 as a guide. The holding plate 25 of the movable spring seat 24 is supported on a torque adjusting male screw 26 fixed to the fixed iron core 10 so as to be able to advance and retract. Here, the adjusting male screw 26 and the pressing plate 25 may be supported using a ball screw. A servo motor (actuator) 28 is attached to the presser plate 25 via a reduction gear unit 27. The control device 29 controls the servo motor 28.

このように構成されたブレーキ装置に置いて、離れた位置からの操作に基づく制御装置29からの指令で、サーボモータ28を回転させると、減速機部27を介して押え板25が回転し、押え板25は可動バネ座24を押圧しているため、可動バネ座24は押え板25と同様に進退する。可動バネ座24が進退すれば、制動用バネ23の圧縮長が変化し、可動鉄心8へのバネ押圧力が変化することになる。その結果、可動バネ座24の進退に基づく、制動用バネ23のバネ押圧力の調整により、ブレーキシュー4,4がディスク2を押圧する制動力が調整される。   When the servo motor 28 is rotated by a command from the control device 29 based on an operation from a distant position on the brake device configured as described above, the presser plate 25 is rotated via the speed reducer unit 27. Since the presser plate 25 presses the movable spring seat 24, the movable spring seat 24 advances and retreats like the presser plate 25. When the movable spring seat 24 advances and retracts, the compression length of the braking spring 23 changes, and the spring pressing force to the movable iron core 8 changes. As a result, the braking force with which the brake shoes 4 and 4 press the disc 2 is adjusted by adjusting the spring pressing force of the braking spring 23 based on the advance and retreat of the movable spring seat 24.

制動用バネ23の圧縮長はサーボモータの位置検出機能により検出できる。このように制動用バネ23の押圧力を電動で調整可能なため、遠隔で制御装置を制御して制動用バネ23のバネ圧の調整が可能となる。
また、制御により自由に制動バネ圧を調整できるので、通常ブレーキ落下時に制動バネ圧を最小化し、落下後にバネ圧を復帰させる等の制御を行うことにより、ライニングとディスクの衝突音を小さくしたり、かごの荷重によりバネ圧を適正に変化させることができる。
また、ブレーキトルク自動検出法と組み合わせれば、ライニングの摩擦係数が変動してもバネ圧を調整して常に一定の制動トルクに保持することができる。
The compression length of the braking spring 23 can be detected by the position detection function of the servo motor. Since the pressing force of the braking spring 23 can be adjusted electrically as described above, the spring pressure of the braking spring 23 can be adjusted by remotely controlling the control device.
In addition, since the brake spring pressure can be adjusted freely by the control, the control of the brake spring pressure is minimized when the brake is dropped, and the spring pressure is restored after the fall. The spring pressure can be appropriately changed by the load of the car.
In combination with the automatic brake torque detection method, even if the friction coefficient of the lining varies, the spring pressure can be adjusted to always maintain a constant braking torque.
