Description

この発明は、機械室レスエレベータに使用されるエレベータ巻上機用ブレーキ装置に関する。   The present invention relates to an elevator hoisting machine brake device used in a machine room-less elevator.

従来のエレベータでは、機械室にエレベータ巻上機が設置されていることもあって、ブレーキ装置は巻上機本体（ギアケース等の筺体）に対し固定された構造となっていた。また、このようなエレベータ巻上機用ブレーキ装置の構造は、機械室レスエレベータに使用されるエレベータ巻上機においてもそのまま踏襲されていた。例えば、日本特開平６−２３４４８４号公報及び日本特開平９−１２４２６０号公報に記載されているように、ブレーキ装置は巻上機本体に対し固定された構造となっていた。 In the conventional elevator, an elevator hoisting machine is installed in the machine room, and thus the brake device is fixed to the hoisting machine main body (a housing such as a gear case). Moreover, the structure of such an elevator hoisting machine brake device has been followed as it is in an elevator hoisting machine used for a machine room-less elevator. For example, as described in Japanese Patent Open Rights 6-234484 JP and Japanese Laid-Open Rights 9-124260, JP-brake system had become fixed to the hoisting machine main body structure.

従来の機械室レスエレベータに使用されるエレベータ巻上機用ブレーキ装置では、ブレーキが巻上機本体に対し固定されているので、重力により特性が変わるようなブレーキ機構にあっては、巻上機の据付位置が昇降路内の上部設置の場合、或いは巻上機の取り付けが反転する昇降路内の下部設置の場合それぞれに合わせて、ブレーキ装置が固定されたエレベータ巻上機を別々に用意し、巻上機の据付位置をブレーキの調整がし易いようにしなければならなかった。したがって、コストアップの原因となっていた。   In the elevator hoisting machine brake device used in a conventional machine room-less elevator, the brake is fixed to the hoisting machine main body. Therefore, in a brake mechanism whose characteristics change due to gravity, the hoisting machine Prepare an elevator hoisting machine with a fixed brake device according to the installation position of the upper part in the hoistway or the lower part of the hoistway where the hoisting machine installation is reversed. The installation position of the hoisting machine had to be made easy to adjust the brake. Therefore, the cost has been increased.

この発明は、このような従来の問題点を解決するもので、ブレーキ装置を巻上機本体に対し取り外し可能な構造として、その取り付け部を回転軸に対し９０°毎に回転可能にすることにより、巻上機の据付位置をブレーキの調整がし易いようにできるエレベータ巻上機用ブレーキ装置を得ることを目的とする。   The present invention solves such a conventional problem, and has a structure in which the brake device can be detached from the hoisting machine main body, and the attachment portion can be rotated about 90 ° with respect to the rotation shaft. An object of the present invention is to provide an elevator hoisting brake device that makes it easy to adjust the position of the hoisting machine.

この発明は、エレベータ巻上機の回転軸に取り付けられるエレベータ巻上機用ブレーキ装置において、ブレーキ装置の取付部を巻上機の回転軸に対し９０°毎に回転可能に取り付け、ブレーキ装置の取付位置を９０°毎に変えられるように構成し、ブレーキ装置は、ブレーキアームが支点ピンを支点に回転するような、重力により影響を受け易い構成のブレーキ機構であって、昇降路内下部に設置した場合は支点ピンを下部に配置し、昇降路内上部に設置した場合は支点ピンを上部に配置することにより、巻上機の取り付け高さ位置によって、ブレーキ装置の方向を変えられるようにしたものである。 The present invention relates to an elevator hoisting machine brake device that is attached to an elevator hoisting machine rotating shaft, wherein the brake device attaching portion is attached to the hoisting machine rotating shaft so as to be rotatable every 90 ° , and the brake device is attached. The position of the brake device can be changed every 90 ° . The brake device is a brake mechanism that is easily affected by gravity so that the brake arm rotates around the fulcrum pin, and is installed in the lower part of the hoistway. In this case, the fulcrum pin is arranged at the lower part, and when it is installed at the upper part in the hoistway, the fulcrum pin is arranged at the upper part, so that the direction of the brake device can be changed depending on the installation height position of the hoist. Is.

Further, the motor portion 5 of the hoisting machine 2 is provided with a brake drum 13 and the like disposed to face the braking piece 12 of the brake device 4. In the figure, reference numeral 14 denotes an elevator car.

このように構成されたエレベータ巻上機用ブレーキ装置では、昇降路内の下部に巻上機２を設置する場合、例えば、第４図に示すように、巻上機２の取り付け高さの位置によって、ブレーキ装置４の方向を変えることができるので、ブレーキの保守をし易い高さにブレーキの調整位置Ａを自由に持っていくことが可能となる。
また、ブレーキアーム９が支点ピン１０を支点に回転するような、重力により影響を受け易い構成のブレーキ装置４にあっても、第１図の昇降路内下部に設置した場合は支点ピン１０を下部に配置し、第５図の昇降路内上部に設置した場合は支点ピン１０を上部に配置することにより、巻上機２の昇降路上下の設置位置に拘らず、ブレーキ装置４を一方向で取り付けることができ、設定基準を均一化することにより保守時のミスを減少することができる。 In the elevator hoisting machine brake device configured as described above, when the hoisting machine 2 is installed at the lower part in the hoistway, for example, as shown in FIG. 4, the position of the mounting height of the hoisting machine 2 Thus, the direction of the brake device 4 can be changed, so that it is possible to freely bring the brake adjustment position A to a height that facilitates maintenance of the brake.
Further, even in the brake device 4 configured to be easily affected by gravity, such as the brake arm 9 rotating about the fulcrum pin 10, the fulcrum pin 10 is not installed when installed in the lower part of the hoistway of FIG. 1. When placed in the lower part and installed in the upper part of the hoistway in FIG. 5, the fulcrum pin 10 is arranged in the upper part so that the brake device 4 can be moved in one direction regardless of the installation position of the hoisting machine 2 above and below the hoistway. By making the setting standard uniform, mistakes during maintenance can be reduced.

実施の形態２．
第６図はこの発明の実施の形態２におけるエレベータ巻上機用ブレーキ装置を示す正面図である。
実施の形態１では、第３図のように、巻上機２のモータ部分５とブレーキ装置４は、互いに矩形体状のフレームであり、その各隅角部にそれぞれ４個の取付穴６を設けていたが、この実施の形態２においては、第６図に示すように、巻上機２のモータ部分５とブレーキ装置４は、互いに丸型のフレームであり、９０°等間隔に４個の取付穴６を設けている。なお、各取付穴６間の縦方向のピッチａと横方向のピッチａは同一に設定され、回転軸３に対して９０°毎に回転可能に取り付けられ、ブレーキ装置４の取付位置が変えられる点は実施の形態１と同様である。 Embodiment 2. FIG.
FIG. 6 is a front view showing a brake device for an elevator hoist according to Embodiment 2 of the present invention.
In the first embodiment, as shown in FIG. 3, the motor portion 5 and the brake device 4 of the hoisting machine 2 are rectangular frames, and four mounting holes 6 are provided at each corner. However, in the second embodiment, as shown in FIG. 6, the motor portion 5 and the brake device 4 of the hoisting machine 2 are round frames, and four pieces are provided at regular intervals of 90 °. Mounting holes 6 are provided. It should be noted that the vertical pitch a and the horizontal pitch a between the mounting holes 6 are set to be the same, and are rotatably mounted on the rotary shaft 3 every 90 °, and the mounting position of the brake device 4 is changed. The point is the same as in the first embodiment.

以上のように、この発明にかかるエレベータ巻上機用ブレーキ装置は、機械室レスエレベータに使用されるエレベータ巻上機用ブレーキ装置として、その取付部を巻上機の回転軸に対し、例えば９０°毎に回転可能にすることにより、巻上機の据付位置をブレーキの調整をし易いようにすることができる。また、重力により特性が変わるようなブレーキ機構であっても、昇降路内の上部設置、巻上機の取り付けが反転する下部設置に拘らず、ブレーキは常に一定方向の取り付けが可能なため、巻上機の取り付けによりブレーキの設定方法、設定条件等を同一に保つことができる。   As described above, the elevator hoisting machine brake device according to the present invention is an elevator hoisting machine brake device used for a machine room-less elevator, and its mounting portion is, for example, 90 with respect to the rotating shaft of the hoisting machine. By making it possible to rotate every degree, it is possible to easily adjust the brakes at the installation position of the hoisting machine. Even with a brake mechanism whose characteristics change due to gravity, the brake can always be mounted in a certain direction regardless of whether it is installed in the upper part of the hoistway or installed in the lower part where the installation of the hoisting machine is reversed. The brake setting method, setting conditions, etc. can be kept the same by installing the upper machine.
