Description

明 細 書 エレベータ用卷上機 技術分野  Description Elevator hoisting machine Technical field
この発明は、 薄型のエレべ一夕用卷上機に関し、 特に内拡式ブレーキを内蔵す るエレべ一夕用卷上機に関するものである。  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thin-type elevator hoisting machine, and more particularly to an elevator hoisting hoist having a built-in inflatable brake.
技術背景 Technology background
従来のエレべ一夕用卷上機において、 狭いスペースに設置可能とする目的で、 略腕状の椀状体の外周面に綱車とブレ キドラムとを一体に設け、 円筒状のブレ —キドラムの周囲に電動機を形成し、 且つブレーキドラムの内側に制動機を配置 して、 薄型化を図ることが提案されている。  In a conventional elevator hoisting machine, a sheave and a brake drum are integrally provided on the outer peripheral surface of a substantially arm-shaped bowl-shaped body in order to enable installation in a narrow space, and a cylindrical brake drum is provided. It has been proposed that a motor be formed around the vehicle and a brake be arranged inside the brake drum to reduce the thickness.
このように、 円筒状のブレーキドラムの内側に制動機を配置したエレべ一夕用 卷上機においては、 ブレーキドラムの内周面に円環状の制動面が形成され、 制動 機はこの制動面に対して摩擦部材を押し付けてブレーキドラム回転速力を落とす 。 この際、 先端に摩擦部材を配した一対のブレーキシュ一が径方向に広がるよう に動作して、 摩擦部材を制動面に押し付ける所謂内拡式ブレーキと呼ばれる構造 にされることが一般的である (例えば、 特開平 2 0 0 0 - 2 8 9 9 5 4号公報の 第 3〜4頁及び第 1〜6図参照） 。  Thus, in an elevator hoisting machine in which a brake is arranged inside a cylindrical brake drum, an annular braking surface is formed on the inner peripheral surface of the brake drum. Against the friction member to reduce the rotational speed of the brake drum. At this time, it is general that a pair of brake shoes having a friction member disposed at the distal end are operated so as to expand in a radial direction, and a structure called a so-called inward expansion type brake is used to press the friction member against the braking surface. (For example, see pages 3 to 4 and FIGS. 1 to 6 of JP-A-2000-289954).
このような構成の所謂内拡式プレーキを有する従来のエレべ一夕用卷上機にお いては、 制動面は摩擦部材に接触して少しずつ摩耗し、 これにより摩擦粉ゃ鑌粉 が発生する。 この摩擦粉ゃ鲭粉のうち、 比較的粒径の大きいものは、 ブレーキド ラムの下部に堆積し、 また、 粒径の小さいものはパウダー状となって密閉された 卷上機内部に飛散する。 そして、 この摩擦粉ゃ鑌粉が制動面に介在すると制動力 が不安定になる。 そのため、 定期的な保守 ·点検の際に、 この摩擦粉や鲭粉を取 り除き制動面を清浄な状態に保つことが必要とされる。 そして、 従来のエレべ一 夕用卷上機においては、 この摩擦粉や鲭粉を取り除く作業が容易でなく、 また取 り除かなければならない頻度が高いので改善が求められていた。 この発明は、 上述のような課題を解決するためになされたもので、 ブレーキド ラムの制動面を長い期間にわたって清浄な状態に保つことができ、 また、 保守 - 点検の際に、 摩擦粉や鲭粉を容易に排出することができるエレべ一夕用卷上機を 得ることを目的とする。 発明の開示 In a conventional hoisting machine for elevators having a so-called inner expansion type brake having such a configuration, the braking surface comes into contact with the friction member and wears little by little, thereby generating friction powder and powder. I do. Of these friction powders, those having a relatively large particle size accumulate at the lower part of the brake drum, and those having a small particle size are scattered into a powdery hermetically sealed hoist. . When the friction powder is present on the braking surface, the braking force becomes unstable. Therefore, during regular maintenance and inspection, it is necessary to remove the friction powder and powder and keep the braking surface clean. In the conventional hoisting machine for elevators, it is not easy to remove the friction powder and the powder, and the frequency of having to remove it is high. The present invention has been made to solve the above-mentioned problems, and can keep a braking surface of a brake drum clean for a long period of time.鲭 It is an object of the present invention to obtain a hoisting machine for an elevator that can easily discharge powder.

制動機 1 3の 1側の下側の制動機 1 3と椀状体 9の間の空間に、 第 1の磁石で ある概略棒状の磁石 2 0が背板 2から立設されている。 磁石 2 0は、 小径円柱状 の磁石本体 2 0 aとこの磁石本体 2 0 aを先端に固定する六角穴付きボルト状の 基部 2 0 bとから構成され、 磁石本体 2 0 aがブレーキドラム 9 cの制動面 9 d に対向するように配置され、 背板 2に穿孔された段付き取付穴 2 bに外側から揷 入されて、 段付き取付穴 2 bの小径穴に螺刻された雌ねじ部にねじ込まれて固定 されている。 図 4に磁石 2 0の形状を示す。 磁石本体 2 0 aは例えばフェライ ト 系の材料である永久磁石で作製されている。 そして、 磁石 2 0は、 磁石本体 2 0 aが、 段付き取付穴 2 bの雌ねじ部より細い径をなしているので、 保守 ·点検の 際に取付穴 2 bから引き抜いて取り外すことができる。 概略棒状の磁石 2 0は、 円環状の制動面 9 dの下部内側にて、 制動面 9 dに微少な隙間を空けて制動面 9 dと平行に立設されている。 そして、 磁石 2 0は、 制動面 9 dと摩擦部材 1 7と が接触する位置に対して、 円周方向に隣接して設けられており、 制動面 9 dに発 生した摩擦粉や鯖粉を即座に吸着する。  In the space between the brake 13 on the lower side of the brake 13 on one side and the bowl 9, a substantially rod-shaped magnet 20 as a first magnet is provided upright from the back plate 2. The magnet 20 is composed of a small-diameter cylindrical magnet body 20a and a hexagon socket head bolt-shaped base 20b for fixing the magnet body 20a to the tip, and the magnet body 20a is a brake drum 9 Female screw which is arranged to face the braking surface 9 d of c and is inserted from the outside into the stepped mounting hole 2 b drilled in the back plate 2 and threaded into the small diameter hole of the stepped mounting hole 2 b It is screwed into the part and fixed. Figure 4 shows the shape of the magnet 20. The magnet main body 20a is made of, for example, a permanent magnet that is a ferrite-based material. Since the magnet body 20a has a smaller diameter than the female screw portion of the stepped mounting hole 2b, the magnet 20 can be pulled out from the mounting hole 2b for maintenance and inspection. The roughly rod-shaped magnet 20 is provided upright inside the lower part of the annular braking surface 9 d with a small gap left between the braking surface 9 d and the braking surface 9 d.

Is immediately absorbed.
また、 2枚の蓋体 4のそれそれ制動機 1 3側に向く面、 すなわち、 ハウジング Also, the surface of each of the two lids 4 facing the brake 13 side, that is, the housing
1と背板 2によって形成された空間に対向する面に、 第 2の磁石である概略半月 形平板状の磁石板 2 1が各々貼着されている。 図 5に磁石板 2 1の形状を示す。 磁石板 2 1は例えばフェライ ト系の材料である永久磁石で作製されている。 そし' て、 磁石板 2 1は、 半月形の窓 2 aの全体を塞ぐ大きさを有している。 磁石板 2 1は、 摩擦部材 1 7と制動面 9 dの互いに接触する面を含む平面が背板 2と交わ る部分とその周辺の部分を含むように広がっている。 磁石板 2 1は、 パウダー状 となって密閉された卷上機内部の空間を飛散する粒径の小さい摩擦粉や鲭粉を吸 着する。 そして、 蓋体 4が上述のように、 背板 2から着脱自在とされているので 、 蓋体 4を取り外すことにより磁石板 2 1も同時に取り外すことができる。 · エレべ一夕の運転時には、 電磁マグネット 1 4の吸引力により、 コイルばね 1 8の復元力に打ち勝って可動鉄心 1 5が吸引され、 摩擦部材 1 7とブレーキドラ ム 9 cの制動面 9 dとの間に所定の空隙が形成され、 制動力は発生しない。 しか し、 エレペータ停止時には、 電磁マグネット 1 4の吸引力が無くなり、 コイルば ね 1 8の復元力により、 摩擦部材 1 7は、 制動面 9 dに押し付けられる。 これに より制動力が発生し綱車 9 bが停止する。 On the surface facing the space formed by the back plate 1 and the back plate 2, a magnet plate 21 having a substantially semicircular flat plate shape as a second magnet is adhered. Figure 5 shows the shape of the magnet plate 21. The magnet plate 21 is made of, for example, a permanent magnet that is a ferrite-based material. Soshi ' The magnet plate 21 has a size that covers the entire half-moon window 2a. The magnet plate 21 extends so that a plane including surfaces of the friction member 17 and the braking surface 9 d that contact each other includes a portion where the back plate 2 intersects and a peripheral portion thereof. The magnet plate 21 adsorbs friction powder or powder having a small particle diameter and scattering in a space inside the winder which is powdery and sealed. Since the cover 4 is detachable from the back plate 2 as described above, the magnet plate 21 can be removed at the same time by removing the cover 4. · During the operation of the elevator, the attractive force of the electromagnetic magnet 14 overcomes the restoring force of the coil spring 18 to attract the movable core 15, and the friction member 17 and the braking surface 9 of the brake drum 9 c A predetermined gap is formed between d and d, and no braking force is generated. However, when the elevator stops, the attractive force of the electromagnetic magnet 14 is lost, and the friction member 17 is pressed against the braking surface 9 d by the restoring force of the coil spring 18. As a result, braking force is generated and the sheave 9b stops.
