Patent Document 2 (Japanese Unexamined Patent Publication No. 64-40286) describes an endless chain in the elevating direction along the main body side of a gondola or the like which is held by a winch so as to be able to move up and down along a wall surface of a building or the like. It is freely supported by a guide rail that forms an elliptical orbit, and the rods are freely expanded and contracted via springs in the radial direction to each link of this chain, and a suction cup is attached to the tip of each rod. Disclosed is a wall surface traveling device in which each suction cup is connected to a vacuum pump via a pipe, and each pipe is provided with a valve that opens and closes according to the movement of the chain.
特許文献３（特開平４－８３０６１号公報）は、建物のパラペットに沿って移動可能なルーフカーにより昇降自在に吊下されたゴンドラを、その両側において昇降案内する一対のガイドパイプと、このガイドパイプに下部において複数のバキュームカップにより建物壁面に連続的に吸着しながら水平移動可能な吸着クローラを備えたゴンドラの横振れ防止装置を開示する。
Patent Document 3 (Japanese Unexamined Patent Publication No. 4-83061) describes a pair of guide pipes for ascending and descending a gondola suspended by a roof car movable along a parapet of a building on both sides thereof, and the guide pipes. Discloses a lateral vibration prevention device for a gondola equipped with a suction crawler that can move horizontally while continuously sucking on a building wall surface by a plurality of vacuum cups at the lower part.
特許文献４（特開平５－７９１７９号公報）は、吊り下げ機によりワイヤを介して建造物の外壁に沿って移動する作業用ゴンドラに、外壁に吸着する吸着盤を設け、これにより、ゴンドラの揺れを防止する作業用ゴンドラを開示する。
In Patent Document 4 (Japanese Unexamined Patent Publication No. 5-79179), a work gondola that moves along an outer wall of a building via a wire by a hanging machine is provided with a suction plate that adsorbs to the outer wall. Disclose a work gondola that prevents shaking.
上述した特許文献１では、無端履帯に沿って複数設けられたリセスのうち壁面に接触しているリセスを真空として壁面に吸着する構造であることから、リセスを壁面に確実に接触させるためには、無端履帯を壁面に沿った方向に強く引っ張っておく必要が生じる。この場合、ロータ間の張力を大きくした場合、ロータが回転しづらくなるという問題が生じる。また、ローラ駆動力とゴンドラ昇降の同期が必要となる。
In the above-mentioned Patent Document 1, since the recesses that are in contact with the wall surface among the plurality of recesses provided along the endless crawler belt are adsorbed to the wall surface as a vacuum, in order to ensure that the recesses are in contact with the wall surface. , It becomes necessary to pull the endless track strongly in the direction along the wall surface. In this case, when the tension between the rotors is increased, there arises a problem that the rotors are difficult to rotate. In addition, it is necessary to synchronize the roller driving force and the gondola ascent and descent.
また、上述した特許文献２では、吸着パッドが常に装置の外側を向いて回転する構成になっている。この特許文献２では、吸着パッドが回転支壁面に接する少し前には、吸着パッドが斜めに壁面方向に移動回転してくるため、吸着パッドが壁面と平行になるまで、接面しないように制御する必要がある。このため、各リンクの中央部を貫通して放射方向にそれぞれロッドが摺動自由に装着され、ロッドの先端にそれぞれ吸盤が取り付けられ、ロッドにはチェーンと吸盤との間に吸盤を外方に付勢するスプリングが嵌装され、ロッドの後部にはガイドレールの内周側に配設されたカムレールに係合するローラが取り付けされ、さらにカムレールはビル壁面側のコーナ部分にそれぞれリフト部が形成され、このリフト部にローラ軸が乗り上げると対応するロッドと共に吸盤が引き上げられるようになっている、等の複雑な構成が必要となる。したがって、特許文献２に開示される壁面走行装置は重く、装置の厚さが厚くなり、ゴンドラと壁面との間に設けることが難しいという問題点を有している。
Further, in Patent Document 2 described above, the suction pad is configured to always rotate toward the outside of the device. In Patent Document 2, shortly before the suction pad comes into contact with the rotating support wall surface, the suction pad moves and rotates diagonally toward the wall surface, so that the suction pad is controlled so as not to come into contact with the wall surface until it is parallel to the wall surface. There is a need to. For this reason, the rods are freely slidably mounted in the radial direction through the central part of each link, and suction cups are attached to the tips of the rods. An urging spring is fitted, a roller that engages with the cam rail arranged on the inner peripheral side of the guide rail is attached to the rear part of the rod, and a lift part is formed on each corner part of the cam rail on the wall surface side of the building. Therefore, when the roller shaft rides on this lift portion, the suction cup is pulled up together with the corresponding rod, and a complicated configuration is required. Therefore, the wall surface traveling device disclosed in Patent Document 2 has a problem that it is heavy, the device becomes thick, and it is difficult to provide it between the gondola and the wall surface.
上述した特許文献３に開示される吸着装置は、ゴンドラ本体に設けられるのではなく、ゴンドラの下部に設けられた吸着装置に固設されたガイドパイプやガイドロープによりゴンドラの振れを削減しようするものであるが、ガイドパイプが長い場合には、風による力に耐えきれず大きく振れることになる。この風による振れ方向と、吸着装置の進行方向とが同じ左右方向である場合には、その左右の振れを抑制することは困難である。
The suction device disclosed in Patent Document 3 described above is not provided in the gondola main body, but is intended to reduce the runout of the gondola by a guide pipe or a guide rope fixed to the suction device provided in the lower part of the gondola. However, if the guide pipe is long, it cannot withstand the force of the wind and swings greatly. When the runout direction due to the wind and the traveling direction of the suction device are the same left and right directions, it is difficult to suppress the left and right runouts.
さらに、特許文献４では、２個の吸盤がレールの長手方向に沿って相対移動可能に係合保持されており、ゴンドラの移動に伴い、バネの伸縮と吸着解除により、連続吸着をさせるものであるが、２個の吸盤の相対運動で、ゴンドラの振れを抑制することは非常に難しいといえる。特に進行に伴い吸着パッドの吸着が１個になった時にゴンドラが振れ始めた場合、離れた吸盤が壁面に最吸着することは非常に難しいといえる。ゴンドラ搭乗者の移動により吸着剥がれを生じた場合も、同様のことが言える。
Further, in Patent Document 4, two suction cups are engaged and held so as to be relatively movable along the longitudinal direction of the rail, and as the gondola moves, the spring expands and contracts and the suction is released to continuously suck the suction cups. However, it can be said that it is very difficult to suppress the runout of the gondola by the relative movement of the two suction cups. In particular, if the gondola begins to swing when the suction pads become one suction pad as the progress progresses, it can be said that it is extremely difficult for the distant suction cups to suck the suction cups to the wall surface most. The same can be said when adsorption peeling occurs due to the movement of the gondola passenger.
以上のことから、ゴンドラの振れ防止装置は、ゴンドラの昇降に合わせて円滑に昇降する必要があること、ゴンドラと壁面間の距離は、人間の手が届く範囲の距離であること、複数個の吸着バッドが常に吸着していることが必要であり、搭乗者の移動等によるゴンドラのローリングが生じた場合にも安定して吸着を維持することが必要である。また、運用上、既存ゴンドラケージの壁面側のどの位置にでも容易に設置できることも重要である。
From the above, the gondola runout prevention device needs to move up and down smoothly as the gondola goes up and down, and the distance between the gondola and the wall surface is within the reach of humans. It is necessary that the suction pad is always sucked, and it is necessary to stably maintain the suction even when the gondola rolls due to the movement of the passenger or the like. In terms of operation, it is also important that it can be easily installed at any position on the wall surface side of the existing gondola cage.
したがって、本発明の課題は、ゴンドラの昇降時のローリングやゴンドラ搭乗者の移動によるゴンドラのローリングが生じても吸着剥離せず、ゴンドラの昇降に合わせて円滑に昇降し、ゴンドラと壁面間の距離が人間の手が届く範囲の距離であり、且つ、複数個の吸着バッドが常に吸着しているという課題を達成できるゴンドラの振れ防止装置を提供することである。
Therefore, the subject of the present invention is that even if the gondola rolls when the gondola goes up and down or the gondola rolls due to the movement of the gondola occupant, the gondola does not adsorb and peel off, and the gondola moves up and down smoothly according to the up and down of the gondola. Is a distance within reach of humans, and is to provide a gondola runout prevention device capable of achieving the problem that a plurality of suction pads are always sucked.
したがって、本発明は、建造物の壁面を移動するゴンドラと該壁面との間に位置するようにゴンドラに設けられるゴンドラの振れ防止装置において、装置本体部が、前記壁面に吸着する吸盤、該吸盤内の空間を真空にする真空発生手段及び前記吸盤内の空間に外気を導入する吸着解除バルブを具備する複数の吸着パッドと、前記ゴンドラの移動に伴って前記吸着パッドを前記壁面に沿って移動させる移動手段と、前記吸着パッドが前記壁面に接触した場合に吸着パッドを吸着させる吸着手段と、前記吸着パッドが前記壁面から離脱する場合に、該吸着パッドの吸着を解除する吸着解除手段とを具備することにある。
Therefore, according to the present invention, in the gondola runout prevention device provided in the gondola so as to be located between the gondola moving on the wall surface of the building and the wall surface, the suction plate whose main body portion is attracted to the wall surface, the suction plate. A plurality of suction pads provided with a vacuum generating means for creating a vacuum in the inner space and a suction release valve for introducing outside air into the space inside the suction plate, and the suction pad is moved along the wall surface as the gondola moves. A moving means for causing the suction pad to be sucked, a suction means for sucking the suction pad when the suction pad comes into contact with the wall surface, and a suction release means for releasing the suction of the suction pad when the suction pad is separated from the wall surface. To be equipped.
これによって、ゴンドラに設けられた振れ防止装置により、ゴンドラが壁面に固定されるため、ゴンドラの振れを防止することができるものである。また、ゴンドラの移動に伴って、その力を利用する自律的な移動手段によって複数の吸着パッドが順次壁面に吸着し、また吸着解除されることから、常に一定の吸着パッドが壁面に吸着していることからゴンドラの振れを確実に防止することができるものである。
As a result, the gondola is fixed to the wall surface by the runout prevention device provided on the gondola, so that the gondola can be prevented from running. In addition, as the gondola moves, a plurality of suction pads are sequentially attracted to the wall surface by an autonomous moving means that utilizes the force, and the suction pads are released from the suction pads, so that a constant suction pad is always attracted to the wall surface. Therefore, it is possible to reliably prevent the gondola from swinging.
また、前記移動手段は、前記本体部内に設けられ、前記ゴンドラの移動方向に沿って回転する一対の回転帯であり、前記吸着パッドの重心から上方にずれた位置に設けられる一対のパッド回転軸が、対応する回転帯のそれぞれに所定の間隔で固定されることが望ましい。これによって、吸着パッドを支持するパッド回転軸が吸着パッドの重心から上方にずれた位置に設けられるので、吸着パッドは、回転帯の回転によって移動しても、自重により常に同一の姿勢が保持される。言い換えれば、回転帯の移動に伴って吸着パッドが移動しても、吸着パッドの吸盤が常に壁面に対向する姿勢を保持できるようになっているものである。
Further, the moving means is a pair of rotating bands provided in the main body and rotating along the moving direction of the gondola, and a pair of pad rotating shafts provided at positions shifted upward from the center of gravity of the suction pad. However, it is desirable that they are fixed at predetermined intervals in each of the corresponding rotation bands. As a result, the pad rotation axis that supports the suction pad is provided at a position shifted upward from the center of gravity of the suction pad, so that the suction pad always maintains the same posture due to its own weight even if it moves due to the rotation of the rotation band. To. In other words, even if the suction pad moves with the movement of the rotating band, the suction cup of the suction pad can always maintain the posture facing the wall surface.
さらに、前記真空発生手段は、前記吸着パッドが前記壁面に移動してきた場合に、吸着パッドに設けられた回転電導子が、前記回転帯に沿って前記本体部に設けられた電導棒に接触することによって、通電されて稼働することが望ましい。このように、吸着パッドが回転帯の移動により壁面側に移動してきた場合、吸着バッドの回転電導子が、本体部に設けられた電導棒に接触することで通電され、真空発生手段が稼働し、吸着パッドが壁面に固定されるものである。尚、真空発生手段は、電動モータによって駆動する真空ポンプであることが望ましい。
Further, in the vacuum generating means, when the suction pad moves to the wall surface, the rotary conductor provided on the suction pad comes into contact with the conductive rod provided on the main body along the rotation band. Therefore, it is desirable to be energized and operate. In this way, when the suction pad moves to the wall surface side due to the movement of the rotating band, the rotating conductor of the suction pad comes into contact with the conductive rod provided in the main body to be energized, and the vacuum generating means operates. , The suction pad is fixed to the wall surface. It is desirable that the vacuum generating means is a vacuum pump driven by an electric motor.
さらにまた、前記吸着解除手段は、前記吸着パッドの回転電導子が電導棒から離脱した後に前記吸着解除バルブが接触する位置に設けられた吸着解除竿であることが望ましい。これにより、前記吸着パッドの回転電導子が電導棒から離脱することによって真空発生手段への通電が停止された後、吸着解除バルブが吸着解除竿に接触するため、吸着パッドの吸盤内の空間に大気が流入して吸盤の吸着が解除されるものである。
Furthermore, it is desirable that the suction release means is a suction release rod provided at a position where the suction release valve comes into contact after the rotary conductor of the suction pad is separated from the conductive rod. As a result, after the rotating conductor of the suction pad is separated from the conduction rod and the energization to the vacuum generating means is stopped, the suction release valve comes into contact with the suction release rod, so that the space inside the suction cup of the suction pad is reached. The air flows in and the suction cups are released from adsorption.
また、前記装置本体部と前記ゴンドラの間には、前記装置本体部と前記ゴンドラの位置を調整するための伸縮機構が設けられることが望ましい。これによって、ゴンドラと壁面との距離に対応して振れ防止装置を確実に壁面に接触させることができるものである。
Further, it is desirable that an expansion / contraction mechanism for adjusting the positions of the device main body and the gondola is provided between the device main body and the gondola. As a result, the runout prevention device can be reliably brought into contact with the wall surface according to the distance between the gondola and the wall surface.
また、ゴンドラの昇降に伴う壁面前後方向へのローリング力による前記装置本体部の引き剥がしを装置本体重心から所定距離上方に、装置本体部支持軸を設け、ゴンドラに懸架するローリング対応機構を設けることが望ましい。これにより、装置本体部はゴンドラの昇降時に働くローリングによる引き剥がし力の影響を相殺することができる。
Further, the device main body is peeled off by the rolling force in the front-rear direction of the wall surface accompanying the raising and lowering of the gondola. The device main body support shaft is provided above the center of gravity of the device by a predetermined distance, and a rolling support mechanism suspended on the gondola is provided. Is desirable. As a result, the main body of the device can offset the influence of the peeling force due to the rolling that acts when the gondola goes up and down.
本発明によれば回転帯に軸支された吸着パッドが必ず壁面に対向していることから、回転帯の回転半径を小さくでき、説明時の吸着パッドを壁面と平行にできるものであり、さらにゴンドラと壁面との距離を５０ｃｍ以内（人の手が届く距離）にできるという効果を奏する。また、複数の吸着パッドによりゴンドラを確実に固定できるため、ゴンドラの揺れを確実に防止できるという効果を奏するものである。
According to the present invention, since the suction pad pivotally supported by the rotating band always faces the wall surface, the radius of gyration of the rotating band can be reduced, and the suction pad at the time of explanation can be made parallel to the wall surface. The effect is that the distance between the gondola and the wall surface can be kept within 50 cm (a distance that humans can reach). Further, since the gondola can be reliably fixed by the plurality of suction pads, the effect of reliably preventing the gondola from shaking is achieved.
また、装置本体とゴンドラ間に設けられたローリング対応機構により、ゴンドラ搭乗者の移動によりゴンドラにローリング力が生じた場合にも、装置本体への引き剥がし力は伝達されないため、装置の複数のパッドは壁面から引き剥がされることはない。
In addition, due to the rolling support mechanism provided between the device body and the gondola, even if a rolling force is generated in the gondola due to the movement of the gondola passenger, the peeling force is not transmitted to the device body, so multiple pads of the device Will not be torn off the wall.

以上の構成により、本発明によれば、ゴンドラ５が下降した場合、前記回転帯１１は、図５及び図６において実線矢印に示される方向に回転し、最も上端に位置する吸着パッド４が壁面３から引き離されると共に、下端側には次の吸着パッド４が壁面３に接近して当接し吸着される。
With the above configuration, according to the present invention, when the gondola 5 is lowered, the rotating band 11 rotates in the direction indicated by the solid arrow in FIGS. 5 and 6, and the suction pad 4 located at the uppermost end is a wall surface. At the same time as being separated from 3, the next suction pad 4 approaches the wall surface 3 and is attracted to the lower end side.
このとき、本体部１０の上端側では、前記吸着パッド４の回転電導子４２が電導棒１３に接触して真空発生装置５０が稼働し、吸着パッド４が壁面３に吸着した状態（図５（ｂ））から、回転電導子４２が電導棒１３から離脱して真空発生装置５０の稼働が停止した後、吸着解除バルブ４５が吸着解除竿６０に接触して吸着が解除される状態（図５（ａ））に至り、回転帯１１の移動に伴って吸着パッド４が壁面３から離脱するものである。
At this time, on the upper end side of the main body 10, the rotating conductive element 42 of the suction pad 4 comes into contact with the conductive rod 13, the vacuum generator 50 operates, and the suction pad 4 is sucked on the wall surface 3 (FIG. 5 (FIG. 5). From b)), after the rotary conductor 42 is separated from the conductive rod 13 and the operation of the vacuum generator 50 is stopped, the suction release valve 45 comes into contact with the suction release rod 60 to release the suction (FIG. 5). (A)), the suction pad 4 is separated from the wall surface 3 as the rotating band 11 moves.
同様に、本体部１０の下端側では、前記吸着パッド４の吸着解除バルブ４５が吸着解除竿６１と接触した後（図６（ｂ））、前記吸着パッドの回転電導子４２が電導棒１３に接触することから、回転帯１１の回転により上昇してきた吸着パッド４が壁面３に吸着するものである（図６（ａ））。
Similarly, on the lower end side of the main body 10, after the suction release valve 45 of the suction pad 4 comes into contact with the suction release rod 61 (FIG. 6B), the rotary conductor 42 of the suction pad is attached to the conduction rod 13. Since they come into contact with each other, the suction pad 4 that has risen due to the rotation of the rotation band 11 is attracted to the wall surface 3 (FIG. 6A).
このように、ゴンドラ５が下降した場合には、回転帯１１の回転に伴って本端部１０の上端側に位置する吸着パッド４の吸着が解除されて壁面３から引き離され、同時に本体部１０の下端側では吸着パッド４が壁面３に接近して吸着が開始されるという動作が順次繰り返され、吸着パッド４が順次下方へ移動するものである。
In this way, when the gondola 5 is lowered, the suction pad 4 located on the upper end side of the main end portion 10 is released from the suction pad 4 as the rotation band 11 rotates, and is separated from the wall surface 3 at the same time. On the lower end side of the above, the operation of the suction pad 4 approaching the wall surface 3 and starting suction is repeated in sequence, and the suction pad 4 moves downward in sequence.
また、ゴンドラ５が上昇した場合、前記回転帯１１は、図５及び図６において一点鎖線矢印に示される方向に回転し、最も下側に位置する吸着パッド４が壁面３から引き離されると共に、最も上側には次の吸着パッド４が壁面３に接近して当接し吸着される。
Further, when the gondola 5 is raised, the rotating band 11 rotates in the direction indicated by the alternate long and short dash arrow in FIGS. 5 and 6, and the suction pad 4 located at the lowermost side is pulled away from the wall surface 3 and is the most. On the upper side, the next suction pad 4 approaches the wall surface 3 and comes into contact with the wall surface 3 for suction.
このとき、前記本体部１０の上端側では、前記吸着パッド４の吸着解除バルブ４５が吸着解除竿６０と接触した後（図５（ａ））、前記吸着パッドの回転電導子４２が電導棒１３に接触することから、回転帯１１の回転により上昇してきた吸着パッド４が壁面３に吸着するものである（図５（ｂ））。
At this time, on the upper end side of the main body 10, after the suction release valve 45 of the suction pad 4 comes into contact with the suction release rod 60 (FIG. 5A), the rotary conductor 42 of the suction pad moves to the conductive rod 13. The suction pad 4 that has risen due to the rotation of the rotating band 11 is attracted to the wall surface 3 because it comes into contact with the wall surface 3 (FIG. 5 (b)).
同様に、前記本体部１０の下端側では、前記吸着パッド４の回転電導子４２が電導棒１３に接触して真空発生装置５０が稼働し、吸着パッド４が壁面３に吸着した状態（図６（ａ））から、回転電導子４２が電導棒１３から離脱して真空発生装置５０の稼働が停止した後、吸着解除バルブ４５が吸着解除竿６１に接触して吸着が解除される状態（図６（ｂ））に至り、回転帯１１の移動に伴って吸着パッド４が壁面３から離脱するものである。
Similarly, on the lower end side of the main body 10, the rotary conductive element 42 of the suction pad 4 comes into contact with the conductive rod 13, the vacuum generator 50 operates, and the suction pad 4 is sucked on the wall surface 3 (FIG. 6). From (a)), after the rotary conductor 42 is separated from the conductive rod 13 and the operation of the vacuum generator 50 is stopped, the suction release valve 45 comes into contact with the suction release rod 61 to release the suction (FIG. 6 (b)) is reached, and the suction pad 4 is separated from the wall surface 3 as the rotating band 11 moves.
このように、ゴンドラ５が上昇した場合には、回転帯１１の回転に伴って本端部１０の下端側に位置する吸着パッド４の吸着が解除されて壁面３から引き離され、同時に本体部１０の上端側では吸着パッド４が壁面３に接近して吸着が開始されるという動作が順次繰り返され、吸着パッド４が順次上方へ移動するものである。
In this way, when the gondola 5 rises, the suction pad 4 located on the lower end side of the main end portion 10 is released from the suction pad 4 as the rotation band 11 rotates, and is separated from the wall surface 3 at the same time. On the upper end side of the above, the operation of the suction pad 4 approaching the wall surface 3 and starting suction is repeated in sequence, and the suction pad 4 moves upward in sequence.
以上、本発明によれば、ゴンドラ５の昇降に対応して振れ防止装置１の吸着パッド４が順次移動し、常に複数の吸着パッド４が壁面３に吸着する状態となっているため、ゴンドラ５の振れを確実に防止することが可能となるものである。
As described above, according to the present invention, the suction pads 4 of the runout prevention device 1 move in sequence in response to the ascent and descent of the gondola 5, and the plurality of suction pads 4 are always sucked on the wall surface 3. Therefore, the gondola 5 It is possible to surely prevent the runout of the.
尚、振れ防止装置１のゴンドラ５への固設に関しては、上述した実施例では、伸縮装置２を介して固設するようにしたが、ゴンドラの昇降に伴う壁面前後方向へのローリング力による振れ防止装置１の引き剥がしを防止するローリング対応機構１５を設けてもよいものである。
Regarding the fixation of the runout prevention device 1 to the gondola 5, in the above-described embodiment, the runout prevention device 1 is fixed via the expansion / contraction device 2, but the runout due to the rolling force in the front-rear direction of the wall surface due to the ascent and descent of the gondola. A rolling corresponding mechanism 15 for preventing the prevention device 1 from being peeled off may be provided.
このローリング対応機構１６は、例えば図７（ａ），（ｂ）に示すもので、前記ゴンドラ５の壁側側面に固着される支持アーム１６ａと、振れ防止装置１の重心Ｇから所定のより上方の位置に設けられた支点軸１５を回転自在に支持する垂直アーム１６ｃと、前記垂直アーム１６ｃと前記支持アーム１６ａの所定位置を連結する連結アーム１６ｂとによって構成される支持竿である。この場合、図７（ａ）、（ｂ）に示すように、ゴンドラ５の昇降に伴い、前後にローリングしても、振れ防止装置１を壁面３から引き剥がす力としては作用しないため、安定的に壁面への吸着を達成することが可能となるものである。
The rolling response mechanism 16 is shown in FIGS. 7A and 7B, for example, and is above a predetermined position from the support arm 16a fixed to the wall side surface of the gondola 5 and the center of gravity G of the runout prevention device 1.
