Part of the foreign matter that has entered between the rope and the brush is removed from the outer peripheral surface of the rope by the rope facing portion, which is the portion of the brush facing the rope. However, the foreign matter clogging the rope-facing portion of the brush lowers the cleaning capability of the brush-facing portion of the brush. As a result, there is a problem that the cleaning ability of the elevator rope cleaning device is reduced.
　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あり、その目的は、清掃能力の低下を抑制することができるエレベータロープ清掃装置を提供するものである。 The present invention has been made to solve the above-described problems, and an object of the present invention is to provide an elevator rope cleaning device capable of suppressing a decrease in cleaning ability.

　また、エレベータは、機械室５に設けられ、ロープ３が巻き掛けられた巻上機６と、機械室５に設けられ、ロープ３が巻き掛けられたそらせ車７とを備えている。なお、この例では、機械室がある場合のエレベータについて説明するが、機械室がない場合のエレベータであってもよい。この場合に、巻上機６は、昇降路１に設けられる。 The elevator includes a hoisting machine 6 provided in the machine room 5 and around which the rope 3 is wound, and a deflector wheel 7 provided in the machine room 5 and around which the rope 3 is wound. In this example, an elevator having a machine room will be described. However, an elevator having no machine room may be used. In this case, the hoist 6 is provided in the hoistway 1.
　また、エレベータは、機械室５の床５１に設けられたエレベータロープ清掃装置８を備えている。エレベータロープ清掃装置８は、ロープ３の外周面に付着している異物を除去する。なお、エレベータロープ清掃装置８は、機械室５の床５１に限らず、例えば、機械室５の壁５２、昇降路１の壁１１などに設けられてもよい。また、昇降路１または機械室５に固定構造物が設けられ、この固定構造物にエレベータロープ清掃装置８が設けられてもよい。また、図１では、巻上機６から下方に延びるロープ３の部分に付着している異物を除去するようにエレベータロープ清掃装置８が配置されているが、そらせ車７から下方に延びるロープ３の部分に付着している異物を除去するようにエレベータロープ清掃装置８が配置されてもよい。 The elevator is provided with an elevator rope cleaning device 8 provided on the floor 51 of the machine room 5. The elevator rope cleaning device 8 removes foreign matters adhering to the outer peripheral surface of the rope 3. The elevator rope cleaning device 8 is not limited to the floor 51 of the machine room 5 and may be provided on, for example, the wall 52 of the machine room 5 or the wall 11 of the hoistway 1. Further, a fixed structure may be provided in the hoistway 1 or the machine room 5, and the elevator rope cleaning device 8 may be provided in the fixed structure. In FIG. 1, the elevator rope cleaning device 8 is disposed so as to remove foreign matter attached to the portion of the rope 3 extending downward from the hoisting machine 6. The elevator rope cleaning device 8 may be arranged so as to remove foreign matter adhering to the portion of the elevator rope.
　ロープ３としては、ワイヤロープ、ベルトなどが挙げられる。この例では、ロープ３として、ワイヤロープが用いられた場合について説明する。 Examples of the rope 3 include a wire rope and a belt. In this example, a case where a wire rope is used as the rope 3 will be described.
　図２は、図１のエレベータロープ清掃装置８を示す正面図、図３は、図２のエレベータロープ清掃装置８を示す側面図である。エレベータロープ清掃装置８は、機械室５の床５１に対して固定されるブラシ取付部材８１と、ブラシ取付部材８１に取り付けられる一対のブラシ８２とを備えている。一対のブラシ８２は、互いに対向するように配置される。一対のブラシ８２の間には、ロープ３が挟まれる。 FIG. 2 is a front view showing the elevator rope cleaning device 8 of FIG. 1, and FIG. 3 is a side view showing the elevator rope cleaning device 8 of FIG. The elevator rope cleaning device 8 includes a brush attachment member 81 fixed to the floor 51 of the machine room 5 and a pair of brushes 82 attached to the brush attachment member 81. The pair of brushes 82 are arranged to face each other. The rope 3 is sandwiched between the pair of brushes 82.
　ブラシ取付部材８１は、互いに対向する一対の固定板８１１と、一対の固定板８１１に渡って設けられた連結板８１２と、一対の固定板８１１のそれぞれに取り付けられた複数の締付具８１３とを有している。一対の固定板８１１の間には、ロープ３が配置される。一対の固定板８１１のそれぞれには、複数の締付具８１３のそれぞれが１本ずつ挿入される複数の長穴８１４が形成されている。長穴８１４は、固定板８１１における幅方向Ａに延びて配置されている。言い換えれば、一対の固定板８１１がロープ３を挟む場合に、長穴８１４は、ロープ３の幅方向Ａに延びるように配置されている。締付具８１３としては、ボルト、ねじなどが挙げられる。 The brush attachment member 81 includes a pair of fixed plates 811 facing each other, a connecting plate 812 provided over the pair of fixed plates 811, and a plurality of fasteners 813 attached to each of the pair of fixed plates 811. have. The rope 3 is arranged between the pair of fixing plates 811. Each of the pair of fixing plates 811 is formed with a plurality of long holes 814 into which each of the plurality of fasteners 813 is inserted one by one. The elongated hole 814 is arranged to extend in the width direction A of the fixing plate 811. In other words, when the pair of fixing plates 811 sandwich the rope 3, the elongated holes 814 are arranged to extend in the width direction A of the rope 3. Examples of the fastener 813 include a bolt and a screw.
　ブラシ８２は、取付板８２１と、取付板８２１に取り付けられた毛部８２２とを有している。取付板８２１には、締付具８１３の先端部が挿入されるねじ溝が形成されている。取付板８２１のねじ溝に締付具８１３の先端部が挿入されることによって、締付具８１３が取付板８２１に取り付けられる。長穴８１４における締付具８１３の位置が変更されることによって、ブラシ取付部材８１に対するロープ３の幅方向Ａについてのブラシ８２の位置が変更可能となっている。 The brush 82 has an attachment plate 821 and a bristle portion 822 attached to the attachment plate 821. The mounting plate 821 has a thread groove into which the tip of the fastener 813 is inserted. The fastener 813 is attached to the attachment plate 821 by inserting the distal end of the fastener 813 into the thread groove of the attachment plate 821. By changing the position of the fastener 813 in the elongated hole 814, the position of the brush 82 in the width direction A of the rope 3 with respect to the brush mounting member 81 can be changed.
　締付具８１３の頭部と取付板８２１とによって固定板８１１が締め付けられることによって、ブラシ取付部材８１に対してブラシ８２が固定される。一方、締付具８１３の頭部と取付板８２１とによる固定板８１１への締付が解除されることによって、ロープ３の幅方向Ａについてのブラシ取付部材８１に対するブラシ８２位置が変更可能となる。 ブ ラ シ The brush 82 is fixed to the brush mounting member 81 by tightening the fixing plate 811 by the head of the tightening tool 813 and the mounting plate 821. On the other hand, when the fastening of the head of the fastener 813 and the mounting plate 821 to the fixing plate 811 is released, the position of the brush 82 with respect to the brush mounting member 81 in the width direction A of the rope 3 can be changed. .
　毛部８２２は、複数本の毛部材から構成されている。毛部８２２は、ロープ３の長手方向に互いに離れて並べて設けられた３個の清掃部８２３と、隣り合う清掃部８２３の間に設けられた２個の異物受部８２４とを有している。異物受部８２４における毛部材の密度は、清掃部８２３における毛部材の密度よりも低い。なお、異物受部８２４には、毛部材が無くてもよい。これにより、単位体積あたりの異物受部８２４の内部に入り込むことができる異物の量は、単位体積あたりの清掃部８２３の内部に入り込むことができる異物の量よりも大きくなる。 The bristle part 822 is composed of a plurality of bristle members. The bristle portion 822 has three cleaning portions 823 provided side by side in the longitudinal direction of the rope 3 so as to be separated from each other, and two foreign matter receiving portions 824 provided between adjacent cleaning portions 823. . The density of the bristle members in the foreign object receiving unit 824 is lower than the density of the bristle members in the cleaning unit 823. The foreign material receiving portion 824 may not have a bristle member. Thus, the amount of foreign matter that can enter the inside of the foreign substance receiving unit 824 per unit volume is larger than the amount of foreign matter that can enter the inside of the cleaning unit 823 per unit volume.
　それぞれの清掃部８２３は、ロープ３の外周面に接触する。清掃部８２３がロープ３の外周面に接触した状態で、ロープ３がブラシ８２に対して移動することによって、ロープ３の外周面から異物が除去される。 清掃 Each cleaning unit 823 contacts the outer peripheral surface of the rope 3. When the rope 3 moves with respect to the brush 82 while the cleaning unit 823 is in contact with the outer peripheral surface of the rope 3, foreign matter is removed from the outer peripheral surface of the rope 3.
　異物受部８２４には、清掃部８２３によってロープ３から除去された異物が溜められる。 異物 The foreign material removed from the rope 3 by the cleaning unit 823 is stored in the foreign material receiving unit 824.
　一対のブラシ８２のうちの一方のブラシ８２の清掃部８２３は、他方のブラシ８２の清掃部８２３と互いに対向する。一対のブラシ８２のうちの一方のブラシ８２の異物受部８２４は、他方のブラシ８２の異物受部８２４と互いに対向する。言い換えれば、両方のブラシ８２の清掃部８２３は、ロープ３における同一部分を互いに反対方向に押す。したがって、ブラシ８２がロープ３を押す方向についてロープ３が移動することが抑制される。 清掃 The cleaning unit 823 of one of the brushes 82 faces the cleaning unit 823 of the other brush 82. The foreign object receiving portion 824 of one of the brushes 82 faces the foreign object receiving portion 824 of the other brush 82. In other words, the cleaning parts 823 of both brushes 82 push the same part of the rope 3 in opposite directions. Therefore, movement of the rope 3 in the direction in which the brush 82 pushes the rope 3 is suppressed.
　例えば、市販のブラシから一部の毛部材が除去されることによって、ブラシ８２が製造される。 For example, the brush 82 is manufactured by removing some bristle members from a commercially available brush.
　次に、エレベータロープ清掃装置８を用いたロープ３の清掃方法について説明する。図４は、図２のエレベータロープ清掃装置８の要部を示す拡大図である。図４の矢印Ｂの方向にロープ３がブラシ８２に対して移動する場合のロープ３の清掃方法について説明する。ロープ３の長手方向に互いに離れて設けられた一対の清掃部８２３のうちで、ロープ３の移動方向について後方側に配置された清掃部８２３を清掃部８２３Ａとし、ロープ３の移動方向について前方側に配置された清掃部８２３を清掃部８２３Ｂとする。異物受部８２４は、清掃部８２３Ａと清掃部８２３Ｂとの間に配置されている。 Next, a method of cleaning the rope 3 using the elevator rope cleaning device 8 will be described. FIG. 4 is an enlarged view showing a main part of the elevator rope cleaning device 8 of FIG. A method of cleaning the rope 3 when the rope 3 moves relative to the brush 82 in the direction of arrow B in FIG. 4 will be described. Of the pair of cleaning units 823 provided apart from each other in the longitudinal direction of the rope 3, the cleaning unit 823 disposed on the rear side in the moving direction of the rope 3 is referred to as a cleaning unit 823A, and the cleaning unit 823A is on the front side in the moving direction of the rope 3. The cleaning unit 823 disposed in is disposed as a cleaning unit 823B. Foreign object receiving portion 824 is arranged between cleaning portion 823A and cleaning portion 823B.
　ロープ３がブラシ８２に対して移動すると、ロープ３の移動方向Ｂにおける後方側を向く清掃部８２３Ａの端部である後方側端部８２５によって、ロープ３の外周面に付着している異物の一部は、ロープ３の外周面から除去される。 When the rope 3 moves with respect to the brush 82, one of the foreign substances adhering to the outer peripheral surface of the rope 3 is removed by the rear end 825 which is the end of the cleaning unit 823 </ b> A facing the rear in the moving direction B of the rope 3. The part is removed from the outer peripheral surface of the rope 3.
　ロープ３の移動方向Ｂについてブラシ８２の後方側端部８２５を通過した異物は、ロープ３と清掃部８２３Ａとの間に進入する。ロープ３と清掃部８２３Ａとの間に進入した異物の一部は、清掃部８２３Ａにおけるロープ３に対向する部分であるロープ対向部分８２６によって、ロープ３の外周面から除去される。ロープ対向部分８２６には、異物が詰まりやすい。したがって、ロープ３と清掃部８２３Ａとの間に進入した異物の一部は、ロープ３と清掃部８２３Ａとの間を通過する。 The foreign matter that has passed through the rear end 825 of the brush 82 in the moving direction B of the rope 3 enters between the rope 3 and the cleaning unit 823A. Part of the foreign matter that has entered between the rope 3 and the cleaning unit 823A is removed from the outer peripheral surface of the rope 3 by a rope facing portion 826 that is a portion of the cleaning unit 823A that faces the rope 3. Foreign matter is easily clogged in the rope facing portion 826. Therefore, part of the foreign matter that has entered between the rope 3 and the cleaning unit 823A passes between the rope 3 and the cleaning unit 823A.
　ロープ３と清掃部８２３Ａとの間を通過する異物は、ロープ３の移動方向Ｂにおける前方側を向く清掃部８２３Ａの端部である前方側端部８２７によって、ロープ３の外周面から除去される。前方側端部８２７によってロープ３の外周面から除去された異物は、異物受部８２４に溜められる。 Foreign matter passing between the rope 3 and the cleaning unit 823A is removed from the outer peripheral surface of the rope 3 by a front end 827 which is an end of the cleaning unit 823A facing the front side in the moving direction B of the rope 3. . The foreign matter removed from the outer peripheral surface of the rope 3 by the front end 827 is stored in the foreign matter receiving portion 824.
　異物受部８２４に多くの異物が溜められた場合には、ロープ３の幅方向Ａについてのブラシ取付部材８１に対するブラシ８２の位置を変更する。これにより、異物受部８２４には、さらに異物を溜めることができる。ここでは、一つの清掃部８２３によるロープ３の清掃について説明したが、これ以外の清掃部８２３によるロープ３の清掃も、この一つの清掃部８２３の清掃と同様である。 If a large amount of foreign matter is accumulated in the foreign matter receiving portion 824, the position of the brush 82 with respect to the brush mounting member 81 in the width direction A of the rope 3 is changed. Thus, foreign matter can be further accumulated in the foreign matter receiving portion 824. Here, the cleaning of the rope 3 by one cleaning unit 823 has been described. However, the cleaning of the rope 3 by the other cleaning unit 823 is the same as the cleaning of the single cleaning unit 823.
　以上説明したように、この発明の実施の形態１に係るエレベータロープ清掃装置８によれば、ブラシ８２は、互いに離れて設けられ、それぞれがロープ３の外周面に接触する一対の清掃部８２３を有している。また、ブラシ８２は、一対の清掃部８２３の間に設けられ、ロープ３から除去された異物が溜められる異物受部８２４を有している。ブラシ８２のロープ対向部分８２６に異物が詰まった場合であっても、異物受部８２４に異物が溜められる。その結果、エレベータロープ清掃装置８の清掃能力の低下を抑制することができる。また、ブラシ８２を交換する頻度を低減させることができる。その結果、ロープ３の清掃時間を短縮することができる。 As described above, according to the elevator rope cleaning device 8 according to Embodiment 1 of the present invention, the brushes 82 are provided separately from each other, and each of the brushes 82 has a pair of cleaning portions 823 that contact the outer peripheral surface of the rope 3. Have. Further, the brush 82 has a foreign matter receiving part 824 that is provided between the pair of cleaning parts 823 and stores the foreign matter removed from the rope 3. Even when foreign matter is clogged in the rope facing portion 826 of the brush 82, foreign matter is accumulated in the foreign matter receiving portion 824. As a result, a decrease in the cleaning ability of the elevator rope cleaning device 8 can be suppressed. Further, the frequency of replacing the brush 82 can be reduced. As a result, the time for cleaning the rope 3 can be reduced.
　また、ブラシ８２が複数の清掃部８２３を有している。これにより、複数のブラシ８２を備えた場合と比較して、ロープ３の長手方向についてエレベータロープ清掃装置８の寸法を小さくすることができる。その結果、狭い空間であっても、エレベータロープ清掃装置８の設置を容易に行うことができる。 ブ ラ シ The brush 82 has a plurality of cleaning units 823. This makes it possible to reduce the size of the elevator rope cleaning device 8 in the longitudinal direction of the rope 3 as compared with the case where a plurality of brushes 82 are provided. As a result, the elevator rope cleaning device 8 can be easily installed even in a narrow space.
　また、ブラシ８２は、ブラシ取付部材８１に対するロープ３の幅方向Ａについての位置が変更可能となっている。ロープ３の幅方向Ａについてのブラシ取付部材８１に対するブラシ８２の位置を変更することによって、エレベータロープ清掃装置８の清掃能力の低下をより確実に抑制することができる。 The position of the brush 82 in the width direction A of the rope 3 with respect to the brush mounting member 81 can be changed. By changing the position of the brush 82 with respect to the brush attachment member 81 in the width direction A of the rope 3, it is possible to more reliably suppress a decrease in the cleaning ability of the elevator rope cleaning device 8.
　また、清掃部８２３および異物受部８２４のそれぞれは、複数本の毛部材から構成されており、異物受部８２４における毛部材の密度は、清掃部８２３における毛部材の密度よりも低い。これにより、簡単な構成では、清掃部８２３および異物受部８２４を製造することができる。 清掃 Further, each of the cleaning unit 823 and the foreign substance receiving unit 824 is configured by a plurality of bristle members, and the density of the bristle members in the foreign substance receiving unit 824 is lower than the density of the bristle members in the cleaning unit 823. Thus, the cleaning unit 823 and the foreign substance receiving unit 824 can be manufactured with a simple configuration.
　なお、実施の形態１では、ロープ３を清掃するエレベータロープ清掃装置８について説明した。しかしながら、これに限らず、例えば、調速機のロープを清掃するエレベータロープ清掃装置であってもよい。この場合、エレベータロープ清掃装置は、例えば、調速機本体を支持する支持台に取り付けられてもよい。 In the first embodiment, the elevator rope cleaning device 8 for cleaning the rope 3 has been described. However, the present invention is not limited to this. For example, an elevator rope cleaning device that cleans the rope of the governor may be used. In this case, the elevator rope cleaning device may be attached to, for example, a support that supports the governor body.
　また、実施の形態１では、３個の清掃部と、２個の異物受部とを備えたブラシ８２の構成について説明した。しかしながら、これに限らず、例えば、一対の清掃部と、１個の異物受部を備えたブラシの構成であってもよい。また、４個以上の清掃部と、３個以上の異物受部とを備えたブラシの構成であってもよい。 In the first embodiment, the configuration of the brush 82 including three cleaning units and two foreign object receiving units has been described. However, the present invention is not limited to this. For example, the brush may be configured to include a pair of cleaning units and a single foreign substance receiving unit.
