Description

エレベーター補償ロープの取付装置Mounting device for elevator compensation rope
　本発明は、昇降路内を、互いに逆方向に昇降するかごおよび釣合おもりと、かごおよび釣合おもりを懸吊する主索と、かごおよび釣合おもりに接続され、昇降路内に吊り下げられるエレベーター補償ロープとを有するエレベーターに用いられる、エレベーター補償ロープの取付装置に関するものである。 The present invention is connected to a car and a counterweight which lifts and lowers each other in a hoistway in the opposite direction, a main rope which suspends the car and the counterweight, and a car and a counterweight, and is suspended in the hoistway. An elevator compensation rope attachment device for use in an elevator having the same.
　近年の高層階用エレベーターにおいては、かご、または釣合おもりの重量に、主索の自重が加わることが無視できない。すなわち、かごが最上階付近または最下階付近にある場合には、主索の自重が、かごおよび釣合おもりの重量のバランスを大きく崩すため、巻上機と主索との間にすべりが生じる。そのため、かごの底部および釣合おもり底部を連結し、昇降路内に垂れ下がるエレベーター補償ロープを設け、主索の自重によるアンバランスを、補償ロープの自重によって相殺する技術が用いられている。 In recent high-rise elevators, it can not be ignored that the weight of the main rope is added to the weight of the car or counterweight. That is, when the car is near the top floor or near the bottom floor, the weight of the main cord largely breaks the balance of the weight of the car and the counterweight, so that there is slippage between the hoist and the main cord. It occurs. Therefore, there is used a technique in which the bottom of the car and the bottom of the counterweight are connected to each other, and an elevator compensation rope hanging down in the hoistway is provided to cancel the unbalance due to the weight of the main rope by the weight of the compensation rope.
　従来のエレベーター補償ロープの取付装置は、エレベーターのかご、または釣合おもりの下部に取り付けられ、補償ロープおよび補償ロープの先端が取り付けられるロープシャックルは、鉛直方向に一直線上に設けられていた。そのため、かご、または釣合おもりの高さが増し、昇降路内の高さ方向のスペースを有効に利用することができなかった。 A conventional elevator compensation rope attachment device is attached to the lower part of an elevator car or a counterweight, and the compensation rope and the rope shackle to which the tip of the compensation rope is attached are vertically aligned. Therefore, the height of the car or the counterweight is increased, and the space in the height direction in the hoistway can not be used effectively.
　特許文献１に記載されたエレベーター補償ロープの取付装置が取り付けられたエレベーターでは、積載おもりとして、おもり片の長手方向が鉛直方向となるように作製された特殊なおもり片が用いられている。おもり片の上下は、釣合おもりの積載室において、積載室の上下の枠に、それぞれ固定されている。また、おもり片の間には、隙間が設けられている。この隙間には、エレベーター補償ロープの先端部が取り付けられるロープシャックルが設けられている。 In the elevator to which the attaching device of the elevator compensation rope described in Patent Document 1 is attached, a special weight made so that the longitudinal direction of the weight becomes the vertical direction is used as the load weight. The upper and lower portions of the weight piece are respectively fixed to upper and lower frames of the loading chamber in the loading chamber of the counterweight. In addition, a gap is provided between the weight pieces. The gap is provided with a rope shackle to which the tip of the elevator compensation rope is attached.
特開２００４－７５３１２号JP 2004-75312
　しかしながら、特許文献１に記載されたエレベーター補償ロープの取付装置をエレベーターに取り付けるためには、積載おもりに、エレベーターごとに、特殊なおもり片を作製し、用いなければいけなかった。 However, in order to attach the elevator compensation rope attachment device described in Patent Document 1 to an elevator, it is necessary to produce and use a special weight for each elevator as a load weight.
　この発明は、上記のような課題を解決するためになされたものであって、積載おもりに、おもり片の長手方向が鉛直方向となるような特殊なおもり片を用いることなく、昇降路内の高さ方向のスペースを有効に利用できるエレベーター補償ロープの取付装置を提供することを目的とするものである。 The present invention has been made to solve the problems as described above, and it is possible to use a load in a hoistway without using a special weight such that the longitudinal direction of the weight is vertical. It is an object of the present invention to provide an elevator compensation rope attachment device that can effectively utilize space in the height direction.
　この発明によるエレベーター補償ロープの取付装置は、昇降路内を、互いに逆方向に昇降するかごおよび釣合おもりと、かごおよび釣合おもりを懸吊する主索と、かごおよび釣合おもりに接続され、昇降路内に吊り下げられるエレベーター補償ロープとを有するエレベーターに用いられる。この発明によるエレベーター補償ロープの取付装置は、かごおよび釣合おもりの少なくとも一方に取り付けられ、エレベーター補償ロープの両端部のうち少なくとも一方において、エレベーター補償ロープの方向を転換する方向転換装置と、エレベーター補償ロープに接続されるロープ端部保持調整部材と、ロープ端部保持調整部材をかごまたは釣合おもりに対して保持する保持具とを有する。 The elevator compensating rope mounting device according to the present invention is connected to the car and the counterweight which lift and lower in the hoistway in opposite directions, the main rope for suspending the car and the counterweight, and the car and the counterweight. , An elevator compensation rope suspended in a hoistway. A device for attaching an elevator compensation rope according to the present invention is attached to at least one of a car and a counterweight, and a redirecting device for diverting the direction of the elevator compensation rope at at least one of the ends of the elevator compensation rope; A rope end holding and adjusting member connected to the rope and a holder for holding the rope end holding and adjusting member against a car or a counterweight.
　この発明のエレベーター補償ロープの取付装置によれば、積載おもりとして、一般的に用いられる平積み用のおもり片を用いることができる。そのため、おもり片の長手方向が鉛直方向となる特殊なおもり片を用いる必要がない。また、エレベーター補償ロープは、昇降路底部の補償ロープ用張り車から上向きに延ばされており、方向転換装置によって、下向きまたは横向きに方向が変えられる。方向が変えられた補償ロープの先端部は、ロープ端部保持調整部材によって固定されている。したがって、ロープ端部保持調整部材は、補償ロープ用張り車の鉛直線上からずれた位置に設けられている。そのため、釣合おもりは、補償ロープ用張り車に接触する直前の位置まで下げることができる。 According to the elevator compensation rope mounting device of the present invention, a flat weight for generally used can be used as the load weight. Therefore, it is not necessary to use a special weight piece in which the longitudinal direction of the weight piece is the vertical direction. Also, the elevator compensation rope is extended upward from the compensation rope sheave at the bottom of the hoistway and is turned downward or sideways by the turning device. The tip of the diverted compensating rope is fixed by means of a rope end holding adjustment member. Therefore, the rope end holding and adjusting member is provided at a position deviated from the vertical line of the compensating rope sheave. Thus, the counterweight can be lowered to a position just before contact with the compensating rope sheave.
　これにより、積載おもりに、おもり片の長手方向が鉛直方向となるような特殊なおもり片を用いることなく、昇降路内の高さ方向のスペースを有効に利用できるエレベーター補償ロープの取付装置を提供することができる。 This provides an elevator compensation rope attachment device that can effectively use the space in the height direction in the hoistway without using a special weight piece such that the longitudinal direction of the weight piece is the vertical direction for the load weight. can do.

FIG. 1 is a block diagram of an entire elevator provided with a device for attaching an elevator compensation rope according to a first embodiment of the present invention.
　昇降路１内には、かご３および釣合おもり４が、主索１０によって吊り下げられ、互いに逆方向の昇降可能に配置されている。
　昇降路１の上部には、機械室５が設けられている。機械室５内には、巻上機６およびそらせ車７が、間隔をあけて設置されている。巻上機６は、駆動装置本体８および駆動綱車９を有している。駆動綱車９は、駆動装置本体８により回転される。駆動綱車９およびそらせ車７には、主索１０が巻き掛けられている。かご３は、巻上機６の駆動力によって、昇降路１内に設けられるかご側ガイドレール２ａに案内されて、昇降路１内を昇降する。また、釣合おもり４は、巻上機６の駆動力によって、昇降路１内に設けられる釣合おもり側ガイドレール２ｂに案内されて、昇降路１内を昇降する。 In the hoistway 1, the car 3 and the counterweight 4 are suspended by the main ropes 10 and are arranged to be able to ascend and descend in opposite directions.
A machine room 5 is provided in the upper part of the hoistway 1. In the machine room 5, a hoisting machine 6 and a deflecting wheel 7 are installed at intervals. The hoisting machine 6 has a drive main body 8 and a drive sheave 9. The drive sheave 9 is rotated by the drive main body 8. A main rope 10 is wound around the drive sheave 9 and the diverter 7. The car 3 is guided by the car-side guide rail 2 a provided in the hoistway 1 by the driving force of the hoisting machine 6 to move up and down in the hoistway 1. Further, the counterweight 4 is guided by the counterweight-side guide rail 2 b provided in the hoistway 1 by the driving force of the hoisting machine 6, and ascends and descends in the hoistway 1.
　釣合おもり４の下部には、エレベーター補償ロープの取付装置３１が設けられている。エレベーター補償ロープの取付装置３１によって、釣合おもり４に、エレベーター補償ロープとしての補償ロープ１１の両端部のうちの一方が取り付けられている。補償ロープ１１は、釣合おもり４の中心に取り付けられている。補償ロープ１１は、昇降路１の底部に設置されている補償ロープ用張り車１２に巻かれている。補償ロープ１１の他方は、かご３の下部に取り付けられている。 At the lower part of the counterweight 4, an elevator compensation rope mounting device 31 is provided. One of the two ends of the compensating rope 11 as the elevator compensating rope is attached to the counterweight 4 by the attaching device 31 of the elevator compensating rope. The compensating rope 11 is attached to the center of the counterweight 4. The compensating rope 11 is wound on a compensating rope support wheel 12 installed at the bottom of the hoistway 1. The other of the compensating ropes 11 is attached to the lower part of the car 3.
　次に、釣合おもり４について、図２を用いて説明する。図２は、図１における釣合おもり４の正面図である。図２は、図１において、ＩＩ－ＩＩ線から見た図である。
　釣合おもり４は、上枠１３、左右一対の吊枠１４、下枠１５を備えている。上枠１３は、主索１０によって懸吊されている。上枠１３および下枠１５の間には、積載おもり１７が平積みされている。積載おもり１７は、左右の吊枠１４によって、水平方向のずれを抑制される。左右の吊枠１４は、下枠１５の下方に延長され、その先端に取付台１６が設けられている。 Next, the counterweight 4 will be described with reference to FIG. FIG. 2 is a front view of the counterweight 4 in FIG. FIG. 2 is a view seen from the II-II line in FIG.
The counterweight 4 includes an upper frame 13, a pair of left and right hanging frames 14, and a lower frame 15. The upper frame 13 is suspended by the main ropes 10. A load weight 17 is stacked between the upper frame 13 and the lower frame 15. The load weight 17 is prevented from being shifted in the horizontal direction by the left and right suspension frames 14. The left and right suspension frames 14 are extended below the lower frame 15, and a mounting base 16 is provided at the tip of the lower frame 15.
　エレベーター補償ロープの取付装置３１は、方向転換装置としての滑車２０、ロープ端部保持調整部材としてのロープシャックル２５、および保持具としてのナット２４を備えている。滑車２０には、補償ロープ１１がかけられている。補償ロープ１１において、先端部１１ａには、ロープシャックル２５が取り付けられている。ロープシャックル２５は、ナット２４によって、取付台１６に取り付けられている。補償ロープ１１において、ロープシャックル２５に取り付けられていない側は、昇降路１の底部の補償ロープ用張り車１２に巻かれている。なお、滑車２０は、回転しない円板でもよい。 The elevator compensating rope mounting device 31 includes a pulley 20 as a turning device, a rope shackle 25 as a rope end holding and adjusting member, and a nut 24 as a holding tool. A compensating rope 11 is hung on the pulley 20. In the compensating rope 11, a rope shackle 25 is attached to the tip end 11a. The rope shackle 25 is attached to the mount 16 by a nut 24. In the compensating rope 11, the side not attached to the rope shackle 25 is wound on a compensating rope support wheel 12 at the bottom of the hoistway 1. The pulley 20 may be a non-rotating disk.
　次に、エレベーター補償ロープの取付装置３１の詳細について、図３および図４を用いて説明する。図３は、エレベーター補償ロープの取付装置３１の正面図であり、図４は側面図である。
　滑車２０は、取付金２１、軸２２、および複数のシーブ２３によって構成される。軸２２およびシーブ２３は、取付金２１によって、下枠１５に取り付けられている。シーブ２３は、軸２２を中心に回転可能である。図４に示すように、綱溝を有する３つのシーブ２３に、それぞれ、補償ロープ１１がかけられている。 Next, details of the elevator compensation rope attachment device 31 will be described with reference to FIGS. 3 and 4. FIG. 3 is a front view of the elevator compensating rope mounting device 31, and FIG. 4 is a side view.
The pulley 20 is constituted by a mounting metal 21, a shaft 22 and a plurality of sheaves 23. The shaft 22 and the sheave 23 are attached to the lower frame 15 by the attachment 21. The sheave 23 is rotatable about an axis 22. As shown in FIG. 4, compensating ropes 11 are respectively applied to three sheaves 23 having a groove.
　図３および図４に示すように、補償ロープ１１の先端部１１ａは、ロープシャックル２５に接続されている。ロープシャックル２５は、金属製であり、ソケット２５ｓ、ロッド２５ｒおよび雄ねじ２５ｆによって構成される。ソケット２５ｓにおいて、先端部１１ａは、例えば、溶融金属もしくはくさびによって固定されている。ロッド２５ｒは、長尺の円柱形の棒である。ソケット２５ｓとロッド２５ｒとは、例えば、ピンによって固定されている。雄ねじ２５ｆは、ロッド２５ｒのソケット２５ｓがついていない側に設けられており、ナット２４によって、取付台１６に保持されている。 As shown in FIGS. 3 and 4, the tip end 11 a of the compensating rope 11 is connected to the rope shackle 25. The rope shackle 25 is made of metal and includes a socket 25s, a rod 25r and an external thread 25f. In the socket 25s, the tip end 11a is fixed by, for example, a molten metal or a wedge. The rod 25r is a long cylindrical rod. The socket 25s and the rod 25r are fixed by, for example, a pin. The male screw 25 f is provided on the side of the rod 25 r on which the socket 25 s is not attached, and is held on the mount 16 by the nut 24.
　次に、実施の形態１のエレベーターの作用を、図２を用いて説明する。
　図２において、例えば、補償ロープ１１が下向きに引かれる場合を考察する。左右の取付台１６には、左右それぞれのロープシャックル２５およびナット２４を介して、一方には時計回りの回転モーメントが生じ、もう一方には反時計回りの回転モーメントが生じる。しかしながら、滑車２０およびナット２４は、釣合おもり４の中心線Ｃ１に対して、左右対称に設けられているため、これらの回転モーメントは釣り合っている。これにより、釣合おもり４に対して、補償ロープ１１によって、時計回りまたは反時計回りの、いずれか一方向の回転モーメントは作用しない。 Next, the operation of the elevator according to the first embodiment will be described with reference to FIG.
Consider, for example, the case where the compensating rope 11 is pulled downward in FIG. On the left and right mounts 16, a clockwise rotational moment is generated on one side and a counterclockwise rotational moment is generated on the other side via the respective rope shackles 25 and the nuts 24 respectively. However, since the pulley 20 and the nut 24 are provided symmetrically with respect to the center line C1 of the counterweight 4, their rotational moments are balanced. Thereby, either clockwise or counterclockwise rotational moment does not act on the counterweight 4 by the compensating rope 11.
　また、ロープシャックル２５、および破線で示す補償ロープ用張り車１２は、水平方向に位置がずれている。したがって、ロープシャックル２５および補償ロープ用張り車１２は、接触しない。すなわち、釣合おもり４は、補償ロープ用張り車１２が滑車２０に接触する直前の位置まで、下げることができる。 Further, the rope shackle 25 and the compensating rope support wheel 12 indicated by a broken line are shifted in the horizontal direction. Thus, the rope shackle 25 and the compensating rope sheave 12 do not touch. That is, the counterweight 4 can be lowered to a position just before the compensating rope support wheel 12 contacts the pulley 20.
　図５は、図２における滑車２０がない場合の、釣合おもり４０の正面図である。釣合おもり４０においては、実施の形態１の場合と同じく、おもり片が平積みである。図５に示すように、下枠１５の下に、第２の下枠２６および第３の下枠２７が設けられている。ロープシャックル２５は、第２の下枠２６に固定されている。ロープシャックル２５は、長尺のロッド２５ｒを有するので、第２の下枠２６から、ロッド２５ｒの長さだけ下方に、第３の下枠２７を設けなければならない。補償ロープ１１は、鉛直方向の一直線上に、ロープシャックル２５に取り付けられている。そのため、釣合おもり４０は、破線で示される補償ロープ用張り車１２が、第３の下枠２７に接触する直前の位置までしか下げることができない。 FIG. 5 is a front view of the counterweight 40 without the pulley 20 in FIG. In the counterweight 40, as in the case of the first embodiment, the weight pieces are stacked flat. As shown in FIG. 5, a second lower frame 26 and a third lower frame 27 are provided below the lower frame 15. The rope shackle 25 is fixed to the second lower frame 26. Since the rope shackle 25 has the long rod 25r, the third lower frame 27 must be provided below the second lower frame 26 by the length of the rod 25r. The compensating rope 11 is attached to the rope shackle 25 on a straight line in the vertical direction. Therefore, the counterweight 40 can be lowered only to a position just before the compensating rope support wheel 12 shown by the broken line contacts the third lower frame 27.
　このように、実施の形態１におけるエレベーター補償ロープの取付装置３１は、昇降路１内を、互いに逆方向に昇降するかご３および釣合おもり４と、かご３および釣合おもり４を懸吊する主索１０と、かご３および釣合おもり４に接続され、昇降路１内に吊り下げられる補償ロープ１１とを有するエレベーターに用いられている。実施の形態１におけるエレベーター補償ロープの取付装置３１は、釣合おもり４に取り付けられ、補償ロープ１１の両端部のうちの一方において、補償ロープ１１の方向を転換する滑車２０と、補償ロープ１１に接続されるロープシャックル２５と、ロープシャックル２５を釣合おもり４に対して保持するナット２４とを有している。 As described above, the elevator compensation rope mounting device 31 according to the first embodiment suspends the car 3 and the counterweight 4, the car 3, and the counterweight 4, which move up and down in the hoistway 1 in opposite directions. It is used in an elevator having a main rope 10 and a compensating rope 11 connected to the car 3 and the counterweight 4 and suspended in the hoistway 1. The elevator compensation rope attachment device 31 according to the first embodiment is attached to the counterweight 4, and the pulley 20 changes the direction of the compensation rope 11 at one of the ends of the compensation rope 11 and the compensation rope 11. It has a rope shackle 25 to be connected and a nut 24 for holding the rope shackle 25 against the counterweight 4.
　実施の形態１のエレベーター補償ロープの取付装置３１によれば、積載おもり１７として、一般的に用いられる平積み用のおもり片を用いることができる。そのため、おもり片の長手方向が鉛直方向となる特殊なおもり片を用いる必要がない。また、補償ロープ１１は、昇降路１の底部の補償ロープ用張り車１２から上向きに延ばされており、滑車２０によって、下向きに方向が変えられる。方向が変えられた補償ロープ１１は、ロープシャックル２５に固定されている。したがって、ロープシャックル２５は、補償ロープ用張り車１２の鉛直線上からずれた位置に設けられている。そのため、釣合おもり４は、補償ロープ用張り車１２に接触する直前の位置まで下げることができる。 According to the attachment device 31 of the elevator compensation rope of the first embodiment, a flat lay piece generally used can be used as the load weight 17. Therefore, it is not necessary to use a special weight piece in which the longitudinal direction of the weight piece is the vertical direction. Further, the compensating rope 11 extends upward from the compensating rope support wheel 12 at the bottom of the hoistway 1 and is turned downward by the pulley 20. The compensating rope 11 whose direction has been changed is fixed to the rope shackle 25. Therefore, the rope shackle 25 is provided at a position deviated from the vertical line of the compensating rope suspension wheel 12. Therefore, the counterweight 4 can be lowered to a position just before contacting the compensating rope support wheel 12.
　これにより、積載おもりに、おもり片の長手方向が鉛直方向となるような特殊なおもり片を用いることなく、昇降路内の高さ方向のスペースを有効に利用できるエレベーター補償ロープの取付装置を提供することができる。 This provides an elevator compensation rope attachment device that can effectively use the space in the height direction in the hoistway without using a special weight piece such that the longitudinal direction of the weight piece is the vertical direction for the load weight. can do.
　滑車２０は２個備えられている。そのため、釣合おもり４に対して、補償ロープ１１による時計回りおよび反時計回りの回転モーメントが釣り合っている。これにより、釣合おもり４は、安定して昇降することが可能である。 Two pulleys 20 are provided. Therefore, the clockwise and counterclockwise rotational moments by the compensating rope 11 are balanced against the counterweight 4. As a result, the counterweight 4 can move up and down stably.
　滑車２０およびナット２４は、釣合おもり４の中心線Ｃ１に対して、左右対称に設けられている。そのため、釣合おもり４に対して、補償ロープ１１による時計回りおよび反時計回りの回転モーメントが釣り合っている。これにより、釣合おもり４は、安定して昇降することが可能である。 The pulley 20 and the nut 24 are provided symmetrically with respect to the center line C1 of the counterweight 4. Therefore, the clockwise and counterclockwise rotational moments by the compensating rope 11 are balanced against the counterweight 4. As a result, the counterweight 4 can move up and down stably.
　エレベーター補償ロープの取付装置３１は、釣合おもり４に取付けられている。そのため、釣合おもり４に設けられたシーブ２３が、おもりの働きをすることができる。これにより、釣合おもり４に積載されるおもり片の数を減らすことができる。また、おもり片の数を減らすことによって、釣合おもり４の高さを減らすことができる。これにより、昇降路内の高さ方向のスペースを、さらに有効に利用できる。 The elevator compensation rope attachment device 31 is attached to the counterweight 4. Therefore, the sheave 23 provided in the counterweight 4 can function as a weight. Thereby, the number of weight pieces loaded on the counterweight 4 can be reduced. Also, the height of the counterweight 4 can be reduced by reducing the number of weight pieces. Thereby, the space in the height direction in the hoistway can be used more effectively.
