Description

本発明は、昇降路上部の狭い場所に用いられて好適なエレベータの巻上機に関するものである。   The present invention relates to an elevator hoisting machine suitable for use in a narrow place at the upper part of a hoistway.

エレベータには乗かごおよびつり合いおもり等の昇降体を昇降させるため、昇降体に接続されたロープを巻上機の綱車に巻き掛け、駆動力を付与するようになっている。そして、エレベータの巻上機は、巻上機の設置場所の条件に応じて設置の向きを変える必要がある。とりわけ、近年、昇降路内に巻上機を設置する機械室レスエレベータが主流になってきているが、このような機械室レスエレベータは、昇降路内の機器設置スペースに制限があることから、巻上機の小型化が求められているとともに、その設置方法の自由度に限りがある。   In order to raise and lower a lifting body such as a passenger car and a counterweight, an elevator is wound around a sheave of a hoisting machine to apply a driving force. And the elevator hoisting machine needs to change the direction of installation according to the conditions of the installation place of the hoisting machine. In particular, in recent years, machine room-less elevators that install hoisting machines in hoistways have become mainstream, but such machine room-less elevators are limited in equipment installation space in hoistways, The hoisting machine is required to be miniaturized, and the degree of freedom of the installation method is limited.

そして、従来、減速機付きの巻上機に備えられた減速機箱を上下対象、或いは左右対称にすることにより、同一減速機を用いつつ、巻上機を昇降路正面から見て左置き、右置きの２種類の使い勝手としたものが提案されている（例えば、特許文献１、２参照）。
特開昭６３−２０８４９１号公報 特公平４−７８５５６号公報 Conventionally, by making the speed reducer box provided in the hoisting machine with a speed reducer vertically or symmetrical, using the same speed reducer, the hoisting machine is placed on the left when viewed from the hoistway front, There have been proposed two types of convenience (see, for example, Patent Documents 1 and 2).
JP-A-63-208491 Japanese Patent Publication No. 4-78556

前述した従来のエレベータの巻上機は、減速機付きの巻上機に係るものであるが、近年、希土類磁石を回転子に使用した同期電動機が主流となり、この同期電動機にあっては、低速高トルクが可能であることから減速機が不要である。そして、従来、この種の同期電動機にあっては、電動機を昇降路正面から見て左置き、右置きとすることについては特別な配慮がなされておらず、異なる形状の巻上機を備えることにより対応していた。   The conventional elevator hoisting machine described above relates to a hoisting machine with a speed reducer, but in recent years, a synchronous motor using a rare earth magnet as a rotor has become mainstream. Since a high torque is possible, a speed reducer is unnecessary. Conventionally, in this type of synchronous motor, no special consideration has been given to placing the motor on the left side and the right side when viewed from the front of the hoistway, and a hoisting machine with a different shape is provided. It corresponded by.

A sheave 8 coupled to the output shaft 7, an output shaft 9 that is rotatably supported by the support member 6b on the other side of the electric motor 6, and a brake 10 that is disposed on the output shaft 9 side of the electric motor 6. The rotation detector 11 is attached to the output shaft 9 and controls the rotation of the electric motor 6. The electric motor 6, the sheave 8, the brake 10, and the rotation detector 11 are arranged in series. .

また、電動機６には、支持部材６ｂと一体的に形成される第１のブラケット１２と、支持部材６ｂに立設された立設部材６ｃに取付けられる第２のブラケット１３とが設けられている。   Further, the electric motor 6 is provided with a first bracket 12 formed integrally with the support member 6b and a second bracket 13 attached to the standing member 6c erected on the support member 6b. .

さらに、制動機１０は、電動機６の他方側の出力軸９に結合されるブレーキドラム１４と、このブレーキドラム１４を挟み込むように対として配置され、一方側にブレーキドラム１４と当接する制動片１５ａ、１５ｂを有して回転支持される制動腕１６ａ、１６ｂと、第２のブラケット１３に固定されるとともに、制動腕１６ａ、１６ｂの他方側にそれぞれロッド１７ａ、１７ｂを介して取付けられ、制動片１６ａ、１６ｂをブレーキドラム１４に押圧する制動ばね１８ａ、１８ｂと、第１のブラケット１２に固定されるとともに、制動腕１６ａ、１６ｂに係合部材１９ａ、１９ｂを介して連結され、制動ばね１８ａ、１８ｂのばね力に反発して制動腕１６ａ、１６ｂを駆動する制動解除手段２０ａ、２０ｂとを備えている。   Further, the brake 10 is disposed as a pair so as to sandwich the brake drum 14 that is coupled to the output shaft 9 on the other side of the electric motor 6, and a brake piece 15 a that contacts the brake drum 14 on one side. The brake arms 16a and 16b that are rotatably supported by the second bracket 13 are fixed to the other side of the brake arms 16a and 16b via rods 17a and 17b, respectively. Brake springs 18a and 18b for pressing 16a and 16b against the brake drum 14, and fixed to the first bracket 12 and connected to the brake arms 16a and 16b via engagement members 19a and 19b, Brake releasing means 20a, 20b for driving the braking arms 16a, 16b against the spring force of 18b is provided.

また、制動機１０は、ブレーキドラム１４と、このブレーキドラム１４を押圧して制動を付加する制動腕１６ａ、１６ｂと、この押圧に抗し制動を解除する制動解除手段２０ａ、２０ｂとで構成され、制動腕１６ａ、１６ｂおよび制動解除手段２０ａ、２０ｂはそれぞれ二組設けられている。そして、これら二組の制動腕１６ａ、１６ｂおよび制動解除手段２０ａ、２０ｂは、それぞれの組がブレーキドラム１４の軸中心を通る直線、つまり、図２および図４では水平方向線に対して上下対称位置に配置される構造であることから、巻上機５が上下いずれの向きとなってもその動作に影響はない。   The brake 10 is composed of a brake drum 14, braking arms 16a and 16b that apply braking by pressing the brake drum 14, and braking release means 20a and 20b that release braking against the pressing. The brake arms 16a and 16b and the brake release means 20a and 20b are provided in two sets. The two sets of braking arms 16a and 16b and the brake releasing means 20a and 20b are vertically symmetrical with respect to a straight line passing through the center of the axis of the brake drum 14, that is, in FIG. 2 and FIG. Since it is the structure arrange | positioned in a position, even if the winding machine 5 becomes any direction up and down, the operation | movement will not be affected.

さらに、支持部材６ａ、６ｂの表裏には、ボルト穴２１が複数設けられ、これらのボルト穴２１を利用して、ベース１ｂに巻上機５がボルト２２により固定されるとともに、巻上機５を吊るための複数のアイボルト２３が取付けられる。   Further, a plurality of bolt holes 21 are provided on the front and back surfaces of the support members 6a and 6b. The hoisting machine 5 is fixed to the base 1b with bolts 22 using these bolt holes 21, and the hoisting machine 5 A plurality of eyebolts 23 for suspending are attached.

本実施形態の巻上機５の動作は次の通りである。制動時は制動ばね１８ａ、１８ｂで制動腕１６ａ、１６ｂを介して制動片１５ａ、１５ｂがブレーキドラム１４の制動面を押圧して制動状態になっている。すなわち、電動機６および綱車８は回転しないので巻上機５は停止している。一方、制動解除時は、制動解除手段２０ａ、２０ｂの図示しない電磁コイルに通電することにより制動ばね１８ａ、１８ｂのばね力に抗して制動腕１６ａ、１６ｂを駆動し、制動片１５ａ、１５ｂがブレーキドラム１４の制動面５ａから離間し制動を解除する。すなわち、電動機６が回転可能状態となるので電動機６に通電して巻上機５を駆動し、綱車８に巻き掛けたロープ４を駆動して乗かご２およびつり合いおもり３を昇降運転する。   The operation of the hoisting machine 5 of the present embodiment is as follows. At the time of braking, the braking pieces 15a and 15b press the braking surface of the brake drum 14 via the braking arms 16a and 16b by the braking springs 18a and 18b, and the braking state is brought about. That is, since the electric motor 6 and the sheave 8 do not rotate, the hoisting machine 5 is stopped. On the other hand, when the brake is released, the brake arms 16a and 16b are driven against the spring force of the brake springs 18a and 18b by energizing an electromagnetic coil (not shown) of the brake release means 20a and 20b. The brake is released from the braking surface 5a of the brake drum 14 and released. That is, since the electric motor 6 is in a rotatable state, the electric motor 6 is energized to drive the hoisting machine 5, and the rope 4 wound around the sheave 8 is driven to raise and lower the car 2 and the counterweight 3.

そして、本実施形態の巻上機５は、図１および図３に示すように電動機６および制動腕１６ａ、１６ｂにより略Ｌ字状の投影面を形成するとともに、制動解除手段２０ａ、２０ｂを制動腕１６ａ、１６ｂの伸長方向に沿うようにして電動機６と並設し、かつ、図２および図４に示すように制動機１０の高さ寸法ｈ１を電動機６の高さ寸法ｈ２未満とした構造とすることにより、電動機６および制動機１０を、電動機６の出力軸９を軸としていずれの方向にも１８０度回転させて使用可能となっている。また、第１のブラケット１２は支持部材６ｂと一体的に形成されるとともに、第２のブラケット１３も立設部材６ｃを介して支持部材６ｂと一体的に設けられ、これによって、第１のブラケット１２および第２のブラケット１３に取付けられる制動機１０は、電動機６、およびこの電動機６の一方側に取付けられる綱車８と一体構造となる。   The hoisting machine 5 of the present embodiment forms a substantially L-shaped projection surface by the electric motor 6 and the braking arms 16a and 16b as shown in FIGS. 1 and 3, and brakes the braking release means 20a and 20b. A structure in which the arms 16a and 16b are arranged in parallel with the electric motor 6 along the extending direction, and the height dimension h1 of the brake 10 is less than the height dimension h2 of the electric motor 6 as shown in FIGS. Thus, the electric motor 6 and the brake 10 can be used by rotating 180 degrees in any direction around the output shaft 9 of the electric motor 6. Further, the first bracket 12 is formed integrally with the support member 6b, and the second bracket 13 is also provided integrally with the support member 6b via the standing member 6c, whereby the first bracket 12 is provided. The brake 10 attached to the 12 and the second bracket 13 has an integral structure with the electric motor 6 and the sheave 8 attached to one side of the electric motor 6.

図１および図２の巻上機５は、巻上機５を昇降路１正面から見て、すなわち巻上機５を綱車８側から見て左方向に制動腕１６ａ、１６ｂが伸長する左置きとなっている。すなわち、制動腕１６ｂが下方、制動腕１６ａが上方に位置するようにして、ベース１ｂに巻上機５をボルト２２により固定する。このとき、制動機１０の高さ寸法ｈ１が電動機６の高さ寸法ｈ２未満であることから、ベース１ｂに巻上機５を固定する際に、制動機１０が邪魔をすることがない。一方、昇降路１の構造および他の機器との兼ね合いから、巻上機５を右置きとするには、図１および図２に示す状態から電動機６の出力軸９を軸として１８０度回転させ、図３および図４に示すように巻上機５を綱車８側から見て右方向に制動腕１６ａ、１６ｂが伸長した状態とする。すなわち、制動腕１６ａが下方、制動腕１６ｂが上方に位置するようにして、ベース１ｂに巻上機５をボルト２２により固定する。また、このとき、制動腕１６ｂ側の支持部材６ａ、６ｂにボルト穴２１を利用して巻上機５を吊るための複数のアイボルト２３が取付けられる。   The hoisting machine 5 shown in FIGS. 1 and 2 is a left side in which the braking arms 16a and 16b extend in the left direction when the hoisting machine 5 is viewed from the front of the hoistway 1, that is, when the hoisting machine 5 is viewed from the sheave 8 side. It is set. That is, the hoisting machine 5 is fixed to the base 1b with the bolts 22 so that the braking arm 16b is positioned downward and the braking arm 16a is positioned upward. At this time, since the height dimension h1 of the brake 10 is less than the height dimension h2 of the electric motor 6, the brake 10 does not interfere when the hoisting machine 5 is fixed to the base 1b. On the other hand, in order to place the hoisting machine 5 on the right side in consideration of the structure of the hoistway 1 and other devices, the hoisting machine 5 is rotated 180 degrees around the output shaft 9 of the electric motor 6 from the state shown in FIGS. 3 and 4, the hoisting machine 5 is in a state where the braking arms 16a and 16b are extended in the right direction when viewed from the sheave 8 side. That is, the hoisting machine 5 is fixed to the base 1b with the bolts 22 so that the braking arm 16a is positioned downward and the braking arm 16b is positioned upward. At this time, a plurality of eye bolts 23 for suspending the hoisting machine 5 are attached to the support members 6a, 6b on the brake arm 16b side using the bolt holes 21.

本実施形態によれば、異なる２つの設置方向に同一機器で対応することができることから、機器の標準化を図り、コストを低減することができる。また、電動機６、綱車８および制動機１０を一体構造とすることにより、巻上機５の搬送および設置を容易なものとすることができる。   According to the present embodiment, since two different installation directions can be handled by the same device, the device can be standardized and the cost can be reduced. Moreover, by making the electric motor 6, the sheave 8, and the brake 10 into an integrated structure, the hoisting machine 5 can be easily transported and installed.
