- This governor rope 4 is attached to the basket endlessly. This governor rope 4 is interlocked with the basket. And the governor rope 4 rotates the sheave 2 according to the raising and lowering of the cage. That is, the sheave 2 changes the rotational speed in one direction according to the ascending speed of the cage, and changes the rotational speed in the other direction according to the descending speed of the cage.
- flyweights 5 On the side surface of the sheave 2, a pair of disk-type flyweights 5 are rotatably provided via pins 6. These flyweights 5 increase or decrease the amount of movement of the sheave 2 radially outward along the side surface of the sheave 2 as the rotational speed of the sheave 2 increases or decreases. These flyweights 5 are connected by a link 7. As a result, the rotation angles of both flyweights 5 are the same.

- a fixed shoe 17 is provided on the opposite side of the rope catch 14. Thereby, the governor rope 4 is surrounded by the rope catch 14 and the fixed shoe 17 below one side of the sheave 2.
- a stopper 18 is further provided.
- the main body of the stopper 18 is rotatably provided on the main shaft 3.
- the main body of the stopper 18 is provided with a pair of locking notches 19.
- the end portions on the center side of the sheave 2 of the locking notches 19 are connected by a connecting notch 20.
- the one end 22 of the lever 21 is penetrated so that movement along this connection notch part 20 is possible.
- the other end 23 of the lever 21 is pivotally supported by the sheave 2.
- a pin 24 protrudes toward the stopper 18 and is provided on the sheave 2 on the main shaft 3 side with respect to the lever 21.
- the lever 25 is also provided with a pin 25 protruding from the sheave 2 side.
- a tension spring 26 is provided between the pins 24 and 25. These tension springs 26 always urge the lever 21 toward the center side of the sheave 2.
- FIGS. 3 to 5 are front views showing main parts of the elevator governor according to the first embodiment of the present invention.
- the flyweight 5 receives a centrifugal force according to the rotational speed of the sheave 2.
- the force by the balance spring 9 is greater than the centrifugal force applied to the flyweight 5. For this reason, the relative position of the flyweight 5 and the sheave 2 does not change from the initial setting state.
- the overspeed switch 13 operates.
- the operating cam 12 and the overspeed switch 13 are detectors that detect overspeed of the sheave 2 when the flyweight 5 moves outward by a predetermined amount regardless of whether the cage is raised or lowered. Function as. Then, the operation of the overspeed switch 13 cuts off the power to the elevator hoist and the brake. Such a shut-off usually stops the basket.
- the flyweight 5 further moves outward in the radial direction of the sheave 2. To do. By this movement, the dog 11 comes into contact with the upper end of the hook 15 from the side of the operating cam 12. By this contact, the hook 15 rotates around the pin 16. Due to the rotation of the hook 15, the lower end of the hook 15 is detached from the rope catch 14.
- the mass of the lever 21 and the spring multiplier of the tension spring 26 are such that the lever 21 moves radially outward of the sheave 2. Is decided.
- the stopper 18 is pushed by the one end 22 of the lever 21 in the rotational direction of the sheave 2. Thereby, the stopper 18 rotates integrally with the sheave 2.
- the ascending direction of the basket exceeds the rated speed, and the flyweight 5 tries to move outward in the radial direction of the sheave 2.
- the protruding end of the stopper 18 is disposed on the radially outer side of the sheave 2 with respect to the flyweight 5. For this reason, if the flyweight 5 moves beyond a predetermined value, it interferes with the protruding end of the stopper 18.
- the flyweight 5 can hardly move outward in the radial direction of the sheave 2. In other words, even if the raising speed of the basket reaches the first overspeed detection speed, the dog 11 at the tip of the flyweight 5 does not contact the operating cam 12. For this reason, the overspeed switch 13 does not operate.
- the stopper 18 tries to continue to rotate at a substantially constant speed according to the law of inertia. For this reason, as shown in FIG. 4, the stopper 18 rotates relative to the sheave 2. Subsequently, when the basket accelerates in the downward direction, the stopper 18 is pushed by the one end 22 of the lever 21. Thereby, the stopper 18 rotates integrally with the sheave 2.
- the stopper 18 causes the flyweight 5 to exceed the predetermined amount by the sheave. 2 is prevented from moving outward in the radial direction. For this reason, it is possible to realize an overspeed detection mechanism with rotation dependency while preventing a decrease in reliability due to generation of vibration / noise and wear of parts with a simple configuration.
- the overspeed detection mechanism to which rotation dependency is added can be realized more stably.
- the threshold value of the rotational speed of the sheave 2 that is set so that the one end 22 of the lever 21 moves radially outward of the sheave 2 is about half of the rated speed that is the lower of the cage ascending and descending speed. It is preferable to set to. In this case, unintentional overspeed detection can be effectively prevented. In order to detect overspeed only when the car is traveling in the upward direction, the flyweight 5 is not prevented from moving when the sheave 2 is rotating in the upward direction of the car.
- the stopper 18 may be configured.

- the force by the balance spring 31 is greater than the centrifugal force applied to the flyweight 29. For this reason, the relative position of the flyweight 29 and the sheave 2 does not change from the initial setting state.
- the overspeed switch 13 operates. That is, the actuating cam 12 and the overspeed switch 13 are detectors that detect overspeed of the sheave 2 when the flyweight 29 moves outward by a predetermined amount regardless of whether the cage is raised or lowered. Function as. Then, the operation of the overspeed switch 13 cuts off the power to the elevator hoist and the brake. Such a shut-off usually stops the basket.

Abstract
Description
しかしながら、例えば、カゴの上昇速度が下降速度よりも速いエレベータのカゴ側調速機においては、カゴの下降速度に合わせて設定した過速検出機構が、カゴの上昇時にも動作してしまう。このため、カゴの上昇速度、下降速度のそれぞれに合わせた過速検出を行うことができないという問題があった。
また、カゴの上昇速度が下降速度よりも速いエレベータにおいて、オモリ側非常止めが適用され、オモリ側調速機が備えられている場合は、カゴの上昇方向の過速検出は、必ずしも、カゴ側調速機で実施する必要はない。しかし、オモリ側調速機を備えることは、冗長な構成となり、コストが高くなるという問題があった。

一般に、エレベータの昇降路は、建築物の各階を跨った鉛直方向に延びる空間からなる。この昇降路上部には、機械室が設けられる。この機械室には、巻上機が設けられる。この巻上機には、巻上ロープが巻回される。この巻上ロープの一端には、エレベータのカゴが吊持される。一方、巻上ロープの他端には、オモリが吊持される。そして、巻上機の回転は、制御装置に制御される。そして、巻上機の回転に追従して、カゴ及びオモリが設定された速度で昇降する。
図1及び図2において、1は調速機である。この調速機1は、綱車2を備える。この綱車2は、主軸3に軸支される。また、綱車2には、調速機ロープ4が巻き掛けられる。
図3~図5はこの発明の実施の形態1におけるエレベータ用調速機の要部を示す正面図である。
綱車2がカゴの昇降と同期して回転すると、綱車2の回転速度に応じた遠心力をフライウエイト5が受ける。ここで、カゴが定格速度以内で昇降している間は、フライウエイト5に加わる遠心力よりも、平衡ばね9による力の方が大きい。このため、フライウエイト5と綱車2との相対位置は、初期設定状態から変化しない。
図6はこの発明の実施の形態2におけるエレベータ用調速機の要部を示す正面図である。なお、実施の形態1と同一又は相当部分には同一符号を付して説明を省略する。
図7はこの発明の実施の形態3におけるエレベータ用調速機の正面図である。図8は図7のB-B線における断面図である。なお、実施の形態1と同一又は相当部分には同一符号を付して説明を省略する。
実施の形態3の調速機1は、実施の形態1の調速機1と、フライウエイトの構成、ストッパ18の形状等が異なるものである。以下、実施の形態3の調速機1を説明する。
綱車2がカゴの昇降と同期して回転すると、綱車2の回転速度に応じた遠心力をフライウエイト29が受ける。ここで、カゴが定格速度以内で昇降している間は、フライウエイト29に加わる遠心力よりも、平衡ばね31による力の方が大きい。このため、フライウエイト29と綱車2との相対位置は、初期設定状態から変化しない。
なお、ストッパ18がある場合の動作は、実施の形態1と同様であるため、説明を省略する。
図9はこの発明の実施の形態4におけるエレベータ用調速機の図8相当図である。なお、実施の形態1と同一又は相当部分には同一符号を付して説明を省略する。
実施の形態3においては、過速検出機構が一つ設けられていた。一方、実施の形態4においては、過速検出機構が二つ設けられている。これらの過速検出機構は、互いに独立して動作する。以下、図9を用いて、実施の形態4の調速機1を説明する。
