変化等によって上下に揺動することを抑制する装置の改
良に関するものである。[Detailed description of the invention] This invention relates to the improvement of a device for suppressing the governor rope from swinging up and down in a small elevator car due to shaking caused by passengers in the car, sudden changes in car acceleration, etc. It is something.
まず第１〜第３図によって従来の調速機ロープの振動抑
制装置を説明する。First, a conventional governor rope vibration suppressing device will be explained with reference to FIGS. 1 to 3.
１はエレベータかご、２は調速機ロープ、３は調速機車
、４は張り車、５はかご非常止め作動レバー（以下作動
レバーと呼ぶ）、６は作動レバー５にボルト７で着脱自

８を貫通しナツト１３で制振ばねの圧縮寸法を規制する
上部ばね受げ、１４はロッド８の上下端でねじ結合され
ロープ２を固定しているソケットである。1 is an elevator car, 2 is a governor rope, 3 is a governor wheel, 4 is a tension wheel, 5 is a car emergency stop activation lever (hereinafter referred to as the activation lever), and 6 is detachably attached to the activation lever 5 with a bolt 7. Fixed angular spring support, 8 is spring support 6
Rods 9 and 10 are provided above and below the spring support 6, passing through the hole 6A provided in the VC with an appropriate gap and having screws 8A at the upper and lower ends, and vibration damping consisting of push springs with the rod 8 passing through the inside. 11 is a lower spring holder that is fixed to the rod 8 by welding or the like and holds the damping spring 10; 12 is an upper spring holder that passes through the rod 8 and regulates the compression dimension of the damping spring with a nut 13; 14 is a spring holder; This is a socket that is screwed together at the upper and lower ends of the rod 8 and fixes the rope 2.
１５は減衰器で、前記調速機ロープ２の振動系に減衰力
を与えるもので下記１６〜２０から構成されている。Reference numeral 15 denotes a damper, which applies a damping force to the vibration system of the governor rope 2, and is comprised of the following components 16 to 20.
１６はかご１にボルト１７で着脱自在に固定され中央に
穴１６ａを有するガイド、１８は穴１６ａの中を自由に
摺動でき一端がロッド８に接している可動摩擦片、１９
は穴１６ａの中に設けられ可動摩擦片１８をロッド８へ
押し付ける押しばね、２０はかご１に固定されロッド８
に接している固定摩擦片である。16 is a guide that is detachably fixed to the car 1 with a bolt 17 and has a hole 16a in the center; 18 is a movable friction piece that can freely slide in the hole 16a and has one end in contact with the rod 8; 19;
20 is a push spring provided in the hole 16a and presses the movable friction piece 18 against the rod 8;
It is a fixed friction piece that is in contact with.
可動摩擦片１８は押しばね１９によってロッド８に対し
て押し付けられているのでロッド８と可動摩擦片１８お
よび固定摩擦片２０との摺動部に摩擦力が生じる。Since the movable friction piece 18 is pressed against the rod 8 by the push spring 19, a frictional force is generated at the sliding portion between the rod 8, the movable friction piece 18, and the fixed friction piece 20.
この力によって調速機ロープ２の振動系に減衰力を与え
ている。This force provides a damping force to the vibration system of the governor rope 2.
制振ばね９，１０には第２図の図示へ寸法より大きい圧
縮寸法が与えであるので、ロッド８がへ寸法だけストロ
ークしても伸張側になった方のばねは圧縮力を失わない
。Since the damping springs 9 and 10 are given a compression dimension that is larger than the dimension shown in FIG. 2, even if the rod 8 strokes by the distance, the spring on the extension side does not lose its compression force.
かご１の下降速度が過大になり調速機の作用速度を越え
ると調速機が動作して調速機ロープ２を把握し、調速機
ロープ２の運動を止めるが、かご１はなお下降を続ける
のでかご１と調速機ロープ２に相対変位が生じ、前記作
動レバー５が引き上げられる。When the descending speed of car 1 becomes excessive and exceeds the operating speed of the speed governor, the speed governor operates and grasps the speed governor rope 2, stopping the movement of speed governor rope 2, but car 1 continues to descend. As this continues, a relative displacement occurs between the car 1 and the governor rope 2, and the operating lever 5 is pulled up.
これによってかご非常止め装置が動作してかご１を非常
停止させる。This causes the car emergency stop device to operate and bring the car 1 to an emergency stop.
図には調速機及びかご非常止め装置の詳細構造は省略し
である。The detailed structures of the speed governor and car emergency stop device are omitted in the figure.
このような構造でかと１と調速機ロープ２とが制振ばね
９，１０を介して間接的に保持されているので、小形エ
レベータ等でかご１が乗客の揺スり等で縦揺れしても、
調速機ロープ２には制振ばね９，１０によってかごの縦
揺れは大巾に減衰されて伝わる。With this structure, the heel 1 and the governor rope 2 are held indirectly through the damping springs 9 and 10, so that the car 1 in a small elevator etc. is prevented from pitching due to the rocking of passengers, etc. Even though
The pitching motion of the car is transmitted to the governor rope 2 while being largely attenuated by damping springs 9 and 10.
またかご１の起動力速度が高く、かつ加速度変化が急激
なときは制振ばね９，１０は調速機ロープ系の慣性力で
撓まされ、次に制振ばね９，１０に蓄積される歪エネル
ギーによって調速機ロープ系が自由振動を起こそうとす
るが、減衰器１５によってこの自由振動は抑制される。Also, when the starting force speed of the car 1 is high and the acceleration change is rapid, the damping springs 9 and 10 are deflected by the inertia of the governor rope system, and then accumulated in the damping springs 9 and 10. Although the governor rope system attempts to cause free vibration due to the strain energy, this free vibration is suppressed by the damper 15.
しかし従来装置は次の３つの欠点があった。However, the conventional device had the following three drawbacks.
すなわち、第１の欠点は毎年行なわれる調速機の作用速
度の定期検査は、調速機ロープ２をかご１より切離して
、調速機ロープ２の作動レバー５側におもり等をつげて
、調速機ロープ２を加速して行なわれるが、このとき調
速機ロープ２をかご１から切り離すのにばね支え６と減
衰器１５のガイド１６を外さねばならず切離すのに多大
な時間を要していた。That is, the first drawback is that the periodic inspection of the operating speed of the speed governor, which is carried out every year, is carried out by separating the speed governor rope 2 from the car 1 and attaching a weight or the like to the operating lever 5 side of the speed governor rope 2. This is done by accelerating the governor rope 2, but at this time, in order to separate the governor rope 2 from the car 1, the spring support 6 and the guide 16 of the damper 15 must be removed, which takes a lot of time. It was necessary.
第２の欠点は非常止メ作動時第３図に示すように作動レ
バー５が回転し、ばね支え６が傾むくので、制動ばね９
，１０が横にふくらむ。The second drawback is that when the emergency stop mechanism is activated, the operating lever 5 rotates and the spring support 6 tilts as shown in FIG.
, 10 expands horizontally.
このふくらみと干渉しないためにエレベータの昇降路機
器やかご回りの機器の配置に制約を受けていた。In order not to interfere with this bulge, there were restrictions on the placement of elevator hoistway equipment and equipment around the car.
これは特に小形エレベータでは昇降路スペースに余裕が
ないため、各機器の配置に強い制約を受けていた。This is especially true for small elevators, which have limited space in the hoistway, which places strong restrictions on the placement of each piece of equipment.
第３の欠点は第３図に示すように非常止め動作時下部ば
ね受げ１１が傾むいたばね支え６に片当りして調速機の
ロープ把持力が加わるためロッド８に曲げが加わる。A third drawback is that, as shown in FIG. 3, during the emergency stop operation, the lower spring receiver 11 hits the inclined spring support 6, and the rope gripping force of the speed governor is applied, so that the rod 8 is bent.
このため従来装置のロッド８は太いものを使用しており
重量が重く、価格も高いものになっていた。For this reason, the rod 8 of the conventional device is thick, heavy, and expensive.
この考案は上記の欠点を解消するもので、狭い据付スペ
ースに配置可能であって、軽量な調速機ロープの振動抑
制装置を提供することを目的としたものである。This invention solves the above-mentioned drawbacks, and aims to provide a lightweight governor rope vibration suppressing device that can be installed in a narrow installation space.
以下第４〜第６図によってこの考案の一実施例を説明す
る。An embodiment of this invention will be described below with reference to FIGS. 4 to 6.
６はアングルが２層になった形状からなりロッド８に遊
挿通された保持体で、作動レバー５に固定されたピン５
Ａに回転自在に取付られている。Reference numeral 6 denotes a holder having a double-layered angle shape, which is loosely inserted into the rod 8, and a pin 5 fixed to the operating lever 5.
It is rotatably attached to A.
２１は両端にフックを有する引ばねで、一端は保持体６
に設けられた穴に取外し可能に係合し、他端は作動レバ
ー５に固定されて、平常運転時は保持体６を作動レバー
に固定されたストッパピン２２に当接するよう引っ張っ
ている。21 is a tension spring having hooks at both ends, and one end is connected to the holder 6.
The other end is fixed to the operating lever 5, and during normal operation, the holding body 6 is pulled so as to come into contact with a stopper pin 22 fixed to the operating lever.
引ばね２１の力は平常運転時のかご１に生じる横揺れに
よって、保持体６が調速機ロープ２の慣性で動き出さな
いよう数に、の力に設定されている。The force of the tension spring 21 is set to a value such that the holding body 6 does not start to move due to the inertia of the governor rope 2 due to the horizontal shaking of the car 1 during normal operation.
これは保持体６が平常運転中動（と、ばね支え６の穴６
Ａとロッド８とが接触してそこに摩擦力が発生して調速
機ロープ２の振動系に与える減衰力が規定値より大きく
なり不具合になるからである。This means that the holding body 6 moves during normal operation (and the hole 6 of the spring support 6
This is because A and the rod 8 come into contact and a frictional force is generated there, and the damping force applied to the vibration system of the governor rope 2 becomes larger than a specified value, causing a problem.
したがって、非常止めが動作するときは第６図に示すよ
うに保持体６は引ばね２１の力に打ち勝って回転するこ
とができる。Therefore, when the emergency stop is activated, the holder 6 can overcome the force of the tension spring 21 and rotate as shown in FIG.
１５は減衰器で板ばね２３，２４から成り、板ばね２３
．２４はばね支え６の上下のばね受げ面６Ｂ 、６Ｃの
間に、保持体６に固定されており、ロッド８を規定バカ
ではさんでいる。15 is an attenuator consisting of leaf springs 23 and 24;
．． 24 is fixed to the holder 6 between the upper and lower spring receiving surfaces 6B and 6C of the spring support 6, and the rod 8 is sandwiched between the specified brackets.
したがって、ロッド８と板ばね２３．２４の摺動部に摩
擦力が生じる。Therefore, a frictional force is generated in the sliding portion between the rod 8 and the leaf springs 23,24.
この摩擦力によって調速機ロープ２の振動系に適正な減
衰力を与えることができる。This frictional force can provide an appropriate damping force to the vibration system of the governor rope 2.
このような横取のため調速機ロープ２をかご１より切離
す際は引ばね２１を保持体６より外し、さらに保持体６
を作動レバー５のピン５Ａよす抜けばよく、従来装置に
比べ切離し作業が簡単になる。When separating the speed governor rope 2 from the car 1 due to such stealing, the tension spring 21 is removed from the holder 6, and then the holder 6 is removed.
All you have to do is pull out the pin 5A of the actuating lever 5, making the disconnection work easier than with conventional devices.
また保持体６はピン５Ａに関して回転可能なため非常止
め動作時にばね支え面６Ｌ６Ｃは水平になるため、制振
ばね９，１０が傾むいて横にふくらむことはなく、また
１部ばね受け１１は全面でばね支え金６Ｃに当たる為ロ
ッド８に曲げが加わらないので前項の不具合は解消され
る。In addition, since the holder 6 is rotatable with respect to the pin 5A, the spring support surface 6L6C becomes horizontal during the emergency stop operation, so the damping springs 9 and 10 do not tilt and bulge sideways, and a portion of the spring receiver 11 is Since the entire surface of the rod 8 hits the spring support 6C, no bending is applied to the rod 8, so the problem mentioned above is solved.
また減衰器１５が保持体６に取付られているので調速機
ロープの振動抑制装置がコンパクトになり取付や発送が
簡便になることと、据付スペースを縮小することができ
る。Furthermore, since the damper 15 is attached to the holder 6, the governor rope vibration suppressing device can be made compact, making it easy to install and ship, and the installation space can be reduced.
第７図はこの考案の他の実施例を示すもので、図中、第
４〜第６図と同符号は相当部分を示す。FIG. 7 shows another embodiment of this invention, in which the same reference numerals as in FIGS. 4 to 6 indicate corresponding parts.
すなわち、第４〜第６図における減衰器１５がばね支え
６に設けられてないものであり、したがって詳細な説明
を省略するがこの実施例においても、作動レバー５の回
動時に制振ばね９，１０がふくらむことがなく、またロ
ッド８に曲げ力が加わることがないので、軽量であって
狭い据付スペースに容易に配置することができる調速機
ロープの振動抑制装置が得られる。That is, the damper 15 in FIGS. 4 to 6 is not provided on the spring support 6. Therefore, although detailed explanation will be omitted, in this embodiment as well, the damping spring 9 is removed when the operating lever 5 is rotated. , 10 do not swell, and no bending force is applied to the rod 8, a governor rope vibration suppressing device that is lightweight and can be easily installed in a narrow installation space is obtained.
以上説明したとおりこの考案は、ロッドが遊挿通されて
