図１はこの発明の実施の形態１におけるエレベーターの巻上機の要部を示す正面図、図２はこの発明の実施の形態１におけるエレベーターの巻上機の要部を示す側面図である。 Embodiment 1 FIG.
FIG. 1 is a front view showing the main part of an elevator hoisting machine according to Embodiment 1 of the present invention, and FIG. 2 is a side view showing the main part of the elevator hoisting machine according to Embodiment 1 of the present invention.

１はエレベーターのかご（図示せず）を駆動するための巻上機である。巻上機１には、綱車２と清掃装置３とが備えられている。
綱車２は、所定の軸に対して回転自在に設けられている。具体的に、綱車２は、基台４にベアリング等を介して回転自在に支持された支持軸５に固定されている。綱車２は、外形が円筒状を呈しており、その外周面に複数の綱溝６が形成されている。各綱溝６には、エレベーターのかごを懸架する主ロープ（図示せず）が巻き掛けられている。エレベーターのかごは、綱車２の回転に連動して主ロープがその長手に移動することにより、主ロープの移動方向に応じた方向に、昇降路内を昇降する。 Reference numeral 1 denotes a hoisting machine for driving an elevator car (not shown). The hoist 1 includes a sheave 2 and a cleaning device 3.
The sheave 2 is provided so as to be rotatable about a predetermined axis. Specifically, the sheave 2 is fixed to a support shaft 5 that is rotatably supported by a base 4 via a bearing or the like. The sheave 2 has a cylindrical outer shape, and a plurality of rope grooves 6 are formed on the outer peripheral surface thereof. A main rope (not shown) for suspending the elevator car is wound around each rope groove 6. The elevator car moves up and down in the hoistway in a direction corresponding to the moving direction of the main rope by moving the main rope along the longitudinal direction in conjunction with the rotation of the sheave 2.

主ロープには、その内部の心綱に油が含まれているため、その油が主ロープの表面からしみ出し、綱車２の綱溝６に付着する。このため、綱車２の綱溝６には、塵埃も付着し易い。清掃装置３は、綱車２の綱溝６を清掃するためのものである。清掃装置３は、例えば、支持台７及び８、清掃用ブラシ９、ブラシ保持具１０、油塵受け１１により、その要部が構成される。   Since the main rope contains oil in the inner rope, the oil oozes out from the surface of the main rope and adheres to the rope groove 6 of the sheave 2. For this reason, dust tends to adhere to the rope groove 6 of the sheave 2. The cleaning device 3 is for cleaning the rope groove 6 of the sheave 2. The main part of the cleaning device 3 is constituted by, for example, the support bases 7 and 8, the cleaning brush 9, the brush holder 10, and the oil dust receiver 11.

支持台７は、ボルト１２によって巻上機１の基台４に、支持台８は、ボルト１３によって支持台７の上面に設けられている。支持台７及び８は、綱車２の直下部に配置されている。   The support base 7 is provided on the base 4 of the hoist 1 with bolts 12, and the support base 8 is provided on the upper surface of the support base 7 with bolts 13. The support bases 7 and 8 are disposed immediately below the sheave 2.

清掃用ブラシ９は、綱溝６を実際に清掃する清掃具を構成する。清掃用ブラシ９は、ブラシ保持具１０の一面から突出するように、ブラシ保持具１０に設けられている。１４は、ブラシ保持具１０を支持台８の上面に固定するためのボルトである。清掃用ブラシ９は、ブラシ保持具１０がボルト１４によって支持台８に固定されることにより、ブラシ保持具１０を介して支持台７及び８に取り付けられる。なお、ブラシ保持具１０がボルト１４によって支持台８の所定の位置に固定されると、清掃用ブラシ９は、その先端部が、綱溝６に対して下方から接触するように配置される。   The cleaning brush 9 constitutes a cleaning tool that actually cleans the rope groove 6. The cleaning brush 9 is provided on the brush holder 10 so as to protrude from one surface of the brush holder 10. Reference numeral 14 denotes a bolt for fixing the brush holder 10 to the upper surface of the support base 8. The cleaning brush 9 is attached to the support bases 7 and 8 via the brush holder 10 by fixing the brush holder 10 to the support base 8 with bolts 14. In addition, when the brush holder 10 is fixed to a predetermined position of the support base 8 with the bolts 14, the cleaning brush 9 is disposed so that the tip end portion thereof contacts the rope groove 6 from below.

清掃用ブラシ９は、綱溝６に接触するその先端部が、綱溝６の溝形状に合わせて凸状に形成されている。また、清掃用ブラシ９（及び、ブラシ保持具１０）は、綱溝６毎に個別に設けられている。即ち、清掃用ブラシ９（及び、ブラシ保持具１０）は、１本の綱溝６に対して１つ設けられており、それぞれが、支持台８に対して個別に取り付け及び取り外しができるように構成されている。   The tip 9 of the cleaning brush 9 that contacts the rope groove 6 is formed in a convex shape in accordance with the groove shape of the rope groove 6. Further, the cleaning brush 9 (and the brush holder 10) is provided for each of the rope grooves 6. That is, one cleaning brush 9 (and brush holder 10) is provided for each rope groove 6 so that each can be individually attached to and detached from the support base 8. It is configured.

油塵受け１１は、清掃用ブラシ９を伝って流れ落ちてきた油塵を受けるためのものである。油塵受け１１は、清掃用ブラシ９の下方に配置されており、清掃用ブラシ９を伝ってきた油塵を受け、その油塵が、巻上機１の基台４や、機械室・昇降路内の各機器に付着することを防止する。本実施の形態では、油塵受け１１を巻上機１の基台４と支持台７との間に配置し、油塵受け１１を、ボルト１２によって支持台７とともに基台４に固定する場合を示している。   The oil dust receiver 11 is for receiving the oil dust that has flowed down through the cleaning brush 9. The oil dust receiver 11 is disposed below the cleaning brush 9, receives the oil dust transmitted through the cleaning brush 9, and the oil dust is transferred to the base 4 of the hoisting machine 1, the machine room, and the elevator Prevents sticking to each device in the road. In the present embodiment, the oil dust receiver 11 is disposed between the base 4 and the support base 7 of the hoisting machine 1, and the oil dust receiver 11 is fixed to the base 4 together with the support base 7 with the bolts 12. Is shown.

上記構成の清掃装置３は、エレベーターの新設時、即ち、エレベーターの稼動開始時から基台４に取り付けられている。本清掃装置３は、ブラシ製の清掃具によって綱溝６を清掃するため、エレベーターの通常運転時に清掃を行っても特に問題は生じない。このため、本清掃装置３では、綱車２が高速回転するエレベーターの通常運転時も、清掃用ブラシ９の先端部を綱溝６に対して下方から常に接触させ、各綱溝６の清掃を行う。   The cleaning device 3 configured as described above is attached to the base 4 when the elevator is newly installed, that is, when the elevator starts operation. Since the present cleaning device 3 cleans the rope groove 6 with a brush cleaning tool, there is no particular problem even if cleaning is performed during normal operation of the elevator. For this reason, in the present cleaning device 3, even during normal operation of the elevator in which the sheave 2 rotates at high speed, the tip of the cleaning brush 9 is always brought into contact with the rope groove 6 from below to clean each rope groove 6. Do.

上記構成の巻上機１であれば、綱溝６の清掃に必要な作業を大幅に簡素化できるとともに、綱溝６を常にきれいな状態に保つことができる。エレベーターの保守時は、従来のように、清掃具の着脱を行ったり、綱溝６の清掃のために低速運転を行ったりする必要がなく、その手間と作業時間とを大幅に低減させることができる。   With the hoist 1 having the above-described configuration, the work required for cleaning the rope groove 6 can be greatly simplified, and the rope groove 6 can always be kept clean. During maintenance of the elevator, it is not necessary to attach / detach the cleaning tool or perform low-speed operation for cleaning the rope groove 6 as in the prior art, and the labor and work time can be greatly reduced. it can.

なお、清掃用ブラシ９が汚れたり、先端部が変形して清掃機能が低下したりした場合は、エレベーターの保守時に、交換が必要な清掃用ブラシ９のみを新品のものに取り替えれば良い。
更に、上記構成の巻上機１であれば、巻上機１の内部やその周囲に油塵が飛び散ることもなく、清潔な状態を常に保つことができる。 If the cleaning brush 9 becomes dirty or the tip portion is deformed to deteriorate the cleaning function, only the cleaning brush 9 that needs to be replaced may be replaced with a new one during maintenance of the elevator.
Furthermore, if it is the winding machine 1 of the said structure, a clean state can always be maintained, without oil dust splashing inside the winding machine 1 or its circumference | surroundings.
