Description

この発明は、エレベータのかご移動規制装置に関するものである。 This invention relates to an elevator car movement restriction device.

従来、作業者が、かごの上で保守作業を行うとき、かごが昇降しないようにするために用いられているエレベータのかご移動規制装置が提案されている（例えば特許文献１参照）。 Conventionally, elevator car movement restriction devices have been proposed that are used to prevent the car from rising or falling when a worker is performing maintenance work on the car (see, for example, Patent Document 1).

ＷＯ２０１７／１１９１１７WO2017/119117

上記従来のかご移動規制装置は、可動部材がかご移動規制位置にある状態自体を検出して、巻上機の駆動を制限するスイッチを１つに減らすことによりコスト低減し、可動部材を弾性体により自動的に収納位置に復帰する装置であった。しかしながら、このスイッチを取り付けるとき、スイッチの押し込み量を見ながらスイッチ取付金の位置調整を行う必要があり、可動部材を所定以上に昇降路側に移動させてしまうと、スイッチが破損するという課題があった。また、スイッチ取付金を取り付ける際、可動部材が所定以上に昇降路側へ移動しないように取付け位置を調整することは容易ではなかった。 The above-mentioned conventional car movement restriction device detects the state in which the movable member is in the car movement restriction position, reduces the number of switches that restrict the operation of the hoist to one, and automatically returns the movable member to the stored position using an elastic body, thereby reducing costs. However, when installing this switch, it is necessary to adjust the position of the switch mounting bracket while checking the amount of depression of the switch, and there was an issue that the switch would be damaged if the movable member was moved more than a specified amount toward the hoistway. In addition, when installing the switch mounting bracket, it was not easy to adjust the mounting position so that the movable member would not move more than a specified amount toward the hoistway.

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り、その目的は、スイッチ取付金の位置調整を行うとき、可動部材がかご移動規制位置に回動したとき、さらにかご移動規制位置側へ回動することがないかご移動規制装置を提供することである。また、スイッチ取付金を取り付ける際、取付け位置が容易に調整できるかご移動規制装置を提供することである。 This invention was made to solve the above problems, and its purpose is to provide a car movement restriction device that, when the position of the switch mounting bracket is adjusted, does not rotate further toward the car movement restriction position when the movable member rotates to the car movement restriction position. It is also to provide a car movement restriction device whose mounting position can be easily adjusted when attaching the switch mounting bracket.

この発明におけるエレベータのかご移動規制装置は、昇降路およびかごの一方に設けられた固定部材と、昇降路およびかごの他方に設けられ、一端に回動軸が形成されており、かご移動規制位置およびかご移動許容位置の間で回動可能であって、かご移動規制位置で他端が固定部材と係合する可動部材と、可動部材がかご移動規制位置にある状態を検知するスイッチと、スイッチを保持する取付金と、可動部材の回動軸側に設けられ、スイッチに当接して可動部材が移動規制位置にある状態が検出される被検出部と、を有するエレベータのかご移動規制装置において、可動部材の長手方向に沿って回動軸側から突出して設けられ、可動部材と共に回動可能であって、可動部材がかご移動規制位置に回動したとき、取付金に当接すると共に可動部材のかご移動規制位置側への回動を規制するストッパ部を備えたことを特徴とするものである。 The elevator car movement restriction device of this invention has a fixed member provided on one side of the hoistway or the car, a movable member provided on the other side of the hoistway or the car, with a pivot shaft formed at one end, rotatable between a car movement restriction position and a car movement permitted position, and the other end engaging with the fixed member at the car movement restriction position, a switch that detects when the movable member is in the car movement restriction position, a mounting bracket that holds the switch, and a detectable part provided on the pivot shaft side of the movable member that abuts against the switch to detect when the movable member is in the movement restriction position, and is characterized by having a stopper part that protrudes from the pivot shaft side along the longitudinal direction of the movable member, is rotatable together with the movable member, and when the movable member rotates to the car movement restriction position, abuts against the mounting bracket and restricts the rotation of the movable member to the car movement restriction position.

この発明は、スイッチ取付金の位置調整を行うとき、可動部材がかご移動規制位置に回動したとき、さらにかご移動規制位置側へ回動することがないかご移動規制装置を実現できる。また、スイッチ取付金を取り付ける際、取付け位置を容易に調整可能なかご移動規制装置を実現できる。 This invention realizes a car movement restriction device that, when the position of the switch mounting bracket is adjusted, does not rotate further toward the car movement restriction position when the movable member rotates to the car movement restriction position. It also realizes a car movement restriction device that allows the mounting position to be easily adjusted when attaching the switch mounting bracket.

図において、本発明のかご移動規制装置１１は、エレベータの昇降路１に設けられた固定部材３と、かご２に設けられ、かご移動規制位置およびかご移動許容位置の間で回動可能な可動部材４と、可動部材４がかご移動許容位置にある状態を検知するスイッチ６と、スイッチ６を保持する取付金７とを備える。 In the figure, the car movement restriction device 11 of the present invention comprises a fixed member 3 provided in the elevator hoistway 1, a movable member 4 provided in the car 2 and capable of rotating between a car movement restriction position and a car movement permitted position, a switch 6 that detects when the movable member 4 is in the car movement permitted position, and a mounting bracket 7 that holds the switch 6.

可動部材４は、回動可能にかご２に支持されている。図１に示されるように、可動部材４の一端に回動軸８が設けられている。回動軸８は、かご２に支持されている。可動部材４の他端には、固定部材３に係合可能な係合部５が設けられている。より詳細には、係合部５は、回動軸８を中心に、弧状に移動することができる。 The movable member 4 is supported by the car 2 so as to be rotatable. As shown in FIG. 1, a rotation shaft 8 is provided at one end of the movable member 4. The rotation shaft 8 is supported by the car 2. An engagement portion 5 that can engage with the fixed member 3 is provided at the other end of the movable member 4. More specifically, the engagement portion 5 can move in an arc around the rotation shaft 8.

固定部材３は、昇降路１と一体的な部分に支持されている。より詳細には、固定部材３は、昇降路１内に設けられたかごガイドレール１２に、ボルト１３によって固定されている。すなわち、固定部材３は、昇降路１に一体に支持されている。また、固定部材３は、板状の部材である。 The fixed member 3 is supported by a part that is integral with the hoistway 1. More specifically, the fixed member 3 is fixed by bolts 13 to a car guide rail 12 provided in the hoistway 1. In other words, the fixed member 3 is supported integrally with the hoistway 1. The fixed member 3 is also a plate-shaped member.

固定部材３には、貫通孔３１が形成されている。可動部材４は、かご移動規制位置では、固定部材３に係合されるため、係合部５が貫通孔３１に挿入されることとなる。可動部材４は、かご移動許容位置では、図１に示されるように、貫通孔３１から退出している。 The fixed member 3 has a through hole 31 formed therein. When the movable member 4 is in the cage movement restricted position, it engages with the fixed member 3, so that the engagement portion 5 is inserted into the through hole 31. When the movable member 4 is in the cage movement permitted position, it retracts from the through hole 31, as shown in FIG. 1.

つまり、可動部材４は、かご移動許容位置において、かご２の移動に伴い貫通孔３１と当接する位置にはなく、かご２の移動に伴い貫通孔３１と干渉しない位置にある。言い換えると、このように可動部材４が、かご２の移動に伴い貫通孔３１と干渉しない位置にあるときが、可動部材４のかご移動許容位置である。 In other words, in the cage movement permitted position, the movable member 4 is not in a position where it abuts against the through hole 31 as the cage 2 moves, and is in a position where it does not interfere with the through hole 31 as the cage 2 moves. In other words, when the movable member 4 is in a position where it does not interfere with the through hole 31 as the cage 2 moves, this is the cage movement permitted position of the movable member 4.

回動軸８に近接するかご２には、取付金７が設けられており、取付金７には、可動部材４がかご移動規制位置にあることを検出するスイッチ６が取り付けられている。また、可動部材４の回動軸８側には、回動軸８と共に回動して、かご移動規制位置に配置されたとき、スイッチ６に当接して可動部材４がかご移動規制位置にある状態が検出される被検出部９が設けられている。 A mounting bracket 7 is provided on the car 2 close to the pivot shaft 8, and a switch 6 is attached to the mounting bracket 7 to detect when the movable member 4 is in the car movement restriction position. In addition, a detection target 9 is provided on the pivot shaft 8 side of the movable member 4, which rotates together with the pivot shaft 8 and abuts against the switch 6 when the movable member 4 is placed in the car movement restriction position to detect that the movable member 4 is in the car movement restriction position.

スイッチ６には、制御装置１４が接続されている。制御装置１４は、スイッチ６からの信号に応じて、かご２を昇降させる駆動装置１５の制御を行っている。可動部材４には、被検出部９が取り付けられている。被検出部９は、可動部材４がかご移動規制位置にあるときに、スイッチ６の作動片と当接して、スイッチ６を作動状態にする。 A control device 14 is connected to the switch 6. The control device 14 controls a drive device 15 that raises and lowers the car 2 in response to a signal from the switch 6. A detectable part 9 is attached to the movable member 4. When the movable member 4 is in the car movement restriction position, the detectable part 9 abuts against the operating piece of the switch 6, putting the switch 6 into an activated state.

スイッチ６は、常閉接点を有しており、安全回路に直列に接続されている。被検出部９によりスイッチ６が作動されると、すなわち、スイッチ６の接点が開くと、制御装置１４により、駆動装置１５への通電が、遮断される。これにより、可動部材４がかご移動許容位置にあるときは、駆動装置１５によるかご２の運転が可能であるが、可動部材４がかご移動規制位置にあるときには、かご２の運転は阻止される。 The switch 6 has a normally closed contact and is connected in series to the safety circuit. When the switch 6 is operated by the detected part 9, that is, when the contact of the switch 6 opens, the control device 14 cuts off the power supply to the drive device 15. As a result, when the movable member 4 is in the car movement permitted position, the drive device 15 can operate the car 2, but when the movable member 4 is in the car movement restricted position, operation of the car 2 is prevented.

また、可動部材４の回動軸８側には、可動部材４の長手方向に沿って回動軸８側に突出して形成されるストッパ部１０が設けられている。ストッパ部１０は、回動軸８を中心に、係合部５と逆方向に弧状に移動することができる。ストッパ部１０は、板状の部材であり、可動部材４がかご移動規制位置にあるとき、取付金７の下端角部に当接して、可動部材４の回動を制限する。 In addition, a stopper portion 10 is provided on the rotating shaft 8 side of the movable member 4, protruding toward the rotating shaft 8 along the longitudinal direction of the movable member 4. The stopper portion 10 can move in an arc around the rotating shaft 8 in the opposite direction to the engagement portion 5. The stopper portion 10 is a plate-shaped member, and when the movable member 4 is in the car movement restriction position, it abuts against the lower corner of the mounting bracket 7 to restrict the rotation of the movable member 4.

ここで、可動部材４がかご移動規制位置にあるとき、係合部５は貫通孔３１に挿入されており、被検出部９はスイッチ６に当接して、ストッパ部１０は取付金７に当接して支持される。また、可動部材４がかご移動許容位置にあるとき、係合部５はかご２側に向けて固定部材３に干渉しない位置に配置されており、被検出部９及びストッパ部１０はスイッチ６及び取付金７に干渉しない昇降路１側に向けて配置される。 When the movable member 4 is in the car movement restriction position, the engagement portion 5 is inserted into the through hole 31, the detected portion 9 abuts against the switch 6, and the stopper portion 10 abuts against the mounting metal 7 and is supported. Also, when the movable member 4 is in the car movement permitted position, the engagement portion 5 is positioned toward the car 2 side so as not to interfere with the fixed member 3, and the detected portion 9 and the stopper portion 10 are positioned toward the elevator shaft 1 side so as not to interfere with the switch 6 and the mounting metal 7.

また、かご移動規制装置１１をかご２に取付け調整する場合、かご２を固定部材３から離れた位置で停止させることがある。この場合、可動部材４は、かご移動規制位置に回動可能であるが、固定部材３の貫通孔３１には挿入されない状態となる。この場合、可動部材４をかご移動規制位置に回動させたとき、ストッパ部１０が取付金７に当接する。そのため、可動部材４及び被検出部９の回動は制限される。このとき、可動部材４がかご移動規制位置側へ回動しないため、被検出部９がスイッチ６に当接した状態が維持される。 In addition, when the car movement restriction device 11 is attached to the car 2 and adjusted, the car 2 may be stopped at a position away from the fixed member 3. In this case, the movable member 4 can rotate to the car movement restriction position, but is not inserted into the through hole 31 of the fixed member 3. In this case, when the movable member 4 is rotated to the car movement restriction position, the stopper portion 10 abuts against the mounting metal 7. Therefore, the rotation of the movable member 4 and the detected portion 9 is restricted. At this time, the movable member 4 does not rotate toward the car movement restriction position, so the detected portion 9 remains in abutment against the switch 6.

次に、上記のように構成された実施の形態１の動作について説明する。始めに、可動部材４をかご２に取付ける。かご２の上部が固定部材３の近傍に配置するようにかご２を移動させる。可動部材４が貫通孔３１に係合するように、かご２の上下位置を調整する。 Next, the operation of the first embodiment configured as described above will be described. First, the movable member 4 is attached to the car 2. The car 2 is moved so that the upper part of the car 2 is positioned near the fixed member 3. The vertical position of the car 2 is adjusted so that the movable member 4 engages with the through hole 31.

可動部材４が貫通孔３１に係合された状態で、予めスイッチ６が組み込まれた取付金７をかご２に取付ける。このとき、ストッパ部１０の可動部材４から突出した端部が取付金７の下端角部に当接するように取付金７の位置を調整する。すなわち、取付金７のかご２との締結用の穴は長穴になっており、可動部材４が係合された状態で、ストッパ部１０を取付金７に押し当てるように調整する。次に、取付金７の取付け位置を水平方向に移動しながら調整して、ストッパ部１０の下端部と取付金７の下端角部とが当接し、かつ被検出部９がスイッチ６によって検出可能な位置に合わせる。 With the movable member 4 engaged in the through hole 31, the mounting bracket 7, which already has the switch 6 built in, is attached to the car 2. At this time, the position of the mounting bracket 7 is adjusted so that the end of the stopper part 10 protruding from the movable member 4 abuts the lower corner of the mounting bracket 7. In other words, the hole for fastening the mounting bracket 7 to the car 2 is an elongated hole, and with the movable member 4 engaged, the stopper part 10 is adjusted to press against the mounting bracket 7. Next, the mounting position of the mounting bracket 7 is adjusted while moving it horizontally until the lower end of the stopper part 10 abuts against the lower corner of the mounting bracket 7 and the detected part 9 is in a position that can be detected by the switch 6.

次に、可動部材４をかご移動規制位置に配置したとき、ストッパ部１０が取付金７に当接して、可動部材４がかご移動規制位置側にさらに回動しないように制限されることを確認する。ここで、いったん可動部材４の固定部材３との係合を解除させる。次に、かご２を上下方向に少し移動させて、可動部材４がかご移動規制位置またはかご移動許容位置のいずれにも回動可能な状態にして、ストッパ部１０及び被検出部９の取付け位置を調整する。 Next, when the movable member 4 is placed in the car movement restriction position, it is confirmed that the stopper portion 10 abuts against the mounting bracket 7, restricting the movable member 4 from further rotating toward the car movement restriction position. At this point, the engagement of the movable member 4 with the fixed member 3 is temporarily released. Next, the car 2 is moved slightly in the vertical direction to allow the movable member 4 to rotate to either the car movement restriction position or the car movement permitted position, and the mounting positions of the stopper portion 10 and the detectable portion 9 are adjusted.

最後に、可動部材４が固定部材３と係合されていない状態で、かつかご移動規制位置に配置された状態で、ストッパ部１０が取付金７に当接して可動部材４の回動が制限されていること、被検出部９がスイッチ６に当接して正常に検出できたことを確認して調整完了となる。 Finally, with the movable member 4 not engaged with the fixed member 3 and placed in the cage movement restriction position, confirm that the stopper portion 10 abuts against the mounting bracket 7 to restrict the rotation of the movable member 4, and that the detected portion 9 abuts against the switch 6 for normal detection, and the adjustment is complete.

上記のように実施の形態１によれば、昇降路１に設けられた固定部材３と、かご２に設けられ、一端に回動軸８が形成されており、かご移動規制位置およびかご移動許容位置の間で回動可能であって、かご移動規制位置で他端が固定部材３と係合する可動部材４と、可動部材４がかご移動規制位置にある状態を検知するスイッチ６と、スイッチ６を保持する取付金７と、可動部材４の回動軸８側に設けられ、スイッチ６に当接して可動部材４が移動規制位置にある状態が検出される被検出部９と、を有するエレベータのかご移動規制装置１１において、可動部材４の長手方向に沿って回動軸８側から突出して設けられ、可動部材４と共に回動可能であって、可動部材４がかご移動規制位置に回動したとき、取付金７に当接すると共に可動部材４のかご移動規制位置側への回動を規制するストッパ部１０を備えたことにより、可動部材４をかご移動規制位置に回動したとき、さらにかご移動規制位置側へ回動することがないため、可動部材４によるスイッチ６の破損を防止可能なかご移動規制装置１１を実現できる。また、取付金７を取り付ける際、かご移動規制位置でストッパ部１０と取付金７とを当接させるだけで位置決めできるため、取付け位置が容易に調整可能なかご移動規制装置１１を実現できる。 As described above, according to embodiment 1, the device has a fixed member 3 provided in the elevator 1, a movable member 4 provided in the car 2, with a pivot shaft 8 formed at one end and rotatable between a car movement restriction position and a car movement permitted position, and the other end of which engages with the fixed member 3 at the car movement restriction position, a switch 6 that detects when the movable member 4 is in the car movement restriction position, a mounting bracket 7 that holds the switch 6, and a detectable portion 9 provided on the pivot shaft 8 side of the movable member 4, which abuts against the switch 6 to detect when the movable member 4 is in the movement restriction position. In the elevator car movement restriction device 11, a stopper portion 10 is provided that protrudes from the rotating shaft 8 side along the longitudinal direction of the movable member 4 and is rotatable together with the movable member 4, and when the movable member 4 rotates to the car movement restriction position, the stopper portion 10 abuts against the mounting metal 7 and restricts the rotation of the movable member 4 toward the car movement restriction position. This prevents the movable member 4 from further rotating toward the car movement restriction position when rotated to the car movement restriction position, thereby realizing a car movement restriction device 11 that can prevent damage to the switch 6 by the movable member 4. In addition, when the mounting metal 7 is attached, it can be positioned simply by abutting the stopper portion 10 and the mounting metal 7 at the car movement restriction position, so that a car movement restriction device 11 whose attachment position can be easily adjusted can be realized.

なお、固定部材３は昇降路１に設けられ、可動部材４はかご１に設けられているが、必ずしもこの位置でなくても良い。例えば、固定部材３はかご１に設けられ、可動部材４は昇降路１に設けられていても良く、同様の作用・効果を奏することは言うまでもない。 Note that the fixed member 3 is provided in the elevator 1 and the movable member 4 is provided in the car 1, but this is not necessarily the case. For example, the fixed member 3 may be provided in the car 1 and the movable member 4 may be provided in the elevator 1, and it goes without saying that the same action and effect will be achieved.

また、かご移動規制位置でストッパ部１０は取付金７に当接する構成であるが、必ずしも同じ構成でなくても良い。例えば、取付金７の代わりにストッパ部１０が当接して同様の作用・効果を奏する部材をかご２に設けても良い。 In addition, the stopper portion 10 is configured to abut against the mounting metal 7 at the cage movement restriction position, but this does not necessarily have to be the case. For example, instead of the mounting metal 7, a member that the stopper portion 10 abuts against and achieves the same function and effect may be provided on the cage 2.

また、かご移動規制装置１１はエレベータのかご２に用いることができるが、必ずしもエレベータのかご２でなくても良い。例えば昇降路が無い建築用ゴンドラであっても、実施の形態１と同様の構成を備えていれば用いることができる。 In addition, the car movement restriction device 11 can be used in an elevator car 2, but it does not necessarily have to be an elevator car 2. For example, it can be used in a construction gondola that does not have a hoistway, as long as it has a configuration similar to that of embodiment 1.
