補助シール部材7の一方の開口部は回転円板部材501の外周縁部に固定され、他方の開口部は負圧シール部材6の延長部604の端部と密着している。
また、該一方の開口部と該他方の開口部との間には両開口部を連結する連結部602が形成されており、而して補助シール部材7は、回転体5及び負圧シール部材6と協働して第2の減圧領域22を規定している。

また、負圧シール部材6には第1の減圧領域21と第2の減圧領域22とを連通する小孔607が設けられている。なお、小孔607も圧力調整手段17いわゆる圧力調整弁を構成する要素である。
弁穴504と小孔607の面積及びバネ定数などの圧縮コイルバネ174の仕様については、第2の減圧領域22の圧力を、物体表面1を包囲する流体の圧力よりも低い圧力に維持し、且つ、第2の減圧領域22の圧力を、第1の減圧領域21の圧力よりも高い圧力に維持する目的に沿って、且つ負圧シール部材6のサイズや負圧生成手段の仕様を勘案しながら適宜決定されるものである。
The rotating disk member 501 of the rotator 5 is provided with a valve hole 504, a valve hole 504, a valve plate 171 that closes the valve hole 504, and a valve that moves in and out of the rotating disk member 501. A rod 172 welded to the plate 171, a rod guide 173 that slidably holds the rod 172, and the valve plate 171 is disposed between the valve plate 171 and the rod guide 173, so that the valve plate 171 is directed to the rotating disc member 501. There is provided a pressure adjusting means 17 composed of a compression coil spring 174 pressed against the pressure coil spring 174.
The negative pressure sealing member 6 is provided with a small hole 607 that communicates the first reduced pressure region 21 and the second reduced pressure region 22. The small hole 607 is also an element constituting the pressure adjusting means 17 so-called a pressure adjusting valve.
Regarding the specifications of the compression coil spring 174 such as the area of the valve hole 504 and the small hole 607 and the spring constant, the pressure of the second decompression region 22 is maintained at a pressure lower than the pressure of the fluid surrounding the object surface 1, and The pressure of the second pressure reducing region 22 is maintained in a higher pressure than the pressure of the first pressure reducing region 21, and the size of the negative pressure sealing member 6 and the specifications of the negative pressure generating means are taken into consideration. It is determined as appropriate.
以下に、上述した装置の作用効果について説明する。
負圧生成手段(図示せず)を付勢すると、第1の減圧領域21の内部の大気の如き流体がサクションホース継手301及びサクションホース(図2において18)を通って外部に排出され、第1の減圧領域21が所要の通り減圧される。
かく第1の減圧領域21が減圧されると、第1の減圧領域21の内外の流体圧力差に起因して装置本体2に作用する大気の如き包囲流体の圧力が2式の駆動車輪11を介して物体表面1に伝達され、かくしてかかる包囲流体圧力によって装置が物体表面1に吸着する。
第1の減圧領域21の内部の圧力が所望の圧力に維持されている時、負圧シール部材6は第1の減圧領域21の内外の圧力差に起因して物体表面1に強く接触せしめられ、よって第1の減圧領域21の外部の流体がその内部に流入するのを極力阻止する。
Below, the effect of the apparatus mentioned above is demonstrated.
When a negative pressure generating means (not shown) is energized, a fluid such as the atmosphere inside the first reduced pressure region 21 is discharged to the outside through the suction hose joint 301 and the suction hose (18 in FIG. 2). One decompression region 21 is decompressed as required.
Thus, when the first depressurization region 21 is depressurized, the pressure of the surrounding fluid acting on the apparatus main body 2 due to the fluid pressure difference between the inside and the outside of the first depressurization region 21 causes the two drive wheels 11 to move. To the object surface 1, and thus the surrounding fluid pressure causes the device to be adsorbed to the object surface 1.
When the pressure inside the first reduced pressure region 21 is maintained at a desired pressure, the negative pressure sealing member 6 is strongly brought into contact with the object surface 1 due to the pressure difference between the inside and outside of the first reduced pressure region 21. Therefore, the fluid outside the first decompression region 21 is prevented from flowing into the inside as much as possible.
かく第1の減圧領域21が減圧されると、第2の減圧領域22の内部の空気の如き流体は、負圧シール部材6に設けられた小孔607を通って第1の減圧領域21へ流入し、よって第2の減圧領域22の圧力は減圧されるが、第2の減圧領域22の圧力が予め設定された任意の圧力を超えて減圧されると、物体表面1を包囲している空気の如き外部流体の圧力が圧縮コイルバネ174の力に打ち勝って弁板171を押し開き、而して小孔607を通って第1の減圧領域21へ流入する流体よりもはるかに流量が多い外部流体が第2の減圧領域22へ流入する。
かく外部流体が第2の減圧領域22へ流入すると、今度は第2の減圧領域22の圧力は増圧されるが、第2の減圧領域22の圧力が予め設定された任意の圧力を超えて増圧されると、圧縮コイルバネ174の力が物体表面1を包囲している空気の如き外部流体の圧力に打ち勝って弁板171を閉じ、而して外部流体の第2の減圧領域22への流入は阻止される。
かくして第2の減圧領域22の圧力は、上記に記載の如く圧力調整手段17の作用により、物体表面1を包囲する流体の圧力よりも低い圧力に維持され、且つ、第1の減圧領域21の圧力よりも高い圧力に維持される。
かく第2の減圧領域22の圧力が、物体表面1を包囲する流体の圧力よりも低い圧力に維持されると、負圧シール部材6と物体表面1との接地圧力が減少するので、而して負圧シール部材6と物体表面1との間の摩擦力が減少される。
なお、第2の減圧領域22の圧力が物体表面1を包囲する流体の圧力と同等であった場合においては、負圧シール部材6と物体表面1との接地圧力が増大するので、而して負圧シール部材6と物体表面1との間の摩擦力が増大され、該摩擦力の増大に起因して装置の走行機能が阻害されるが、該走行機能に係る作用の説明の項で該阻害の内容について詳述する。
Thus, when the first decompression region 21 is decompressed, a fluid such as air inside the second decompression region 22 passes through the small hole 607 provided in the negative pressure seal member 6 to the first decompression region 21. Inflow, and thus the pressure in the second decompression region 22 is decompressed. However, when the pressure in the second decompression region 22 exceeds a predetermined pressure, the object surface 1 is surrounded. The pressure of the external fluid such as air overcomes the force of the compression coil spring 174 to push the valve plate 171 open, and thus the flow rate is much higher than the fluid flowing into the first decompression region 21 through the small hole 607. The fluid flows into the second reduced pressure region 22.
Thus, when the external fluid flows into the second decompression region 22, the pressure in the second decompression region 22 is increased, but the pressure in the second decompression region 22 exceeds the preset arbitrary pressure. When the pressure is increased, the force of the compression coil spring 174 overcomes the pressure of an external fluid such as air surrounding the object surface 1 to close the valve plate 171, and thus the external fluid is applied to the second decompression region 22. Inflow is blocked.
Thus, the pressure in the second reduced pressure region 22 is maintained at a pressure lower than the pressure of the fluid surrounding the object surface 1 by the action of the pressure adjusting means 17 as described above. The pressure is maintained higher than the pressure.
Thus, if the pressure in the second decompression region 22 is maintained at a pressure lower than the pressure of the fluid surrounding the object surface 1, the ground pressure between the negative pressure seal member 6 and the object surface 1 is reduced. Thus, the frictional force between the negative pressure sealing member 6 and the object surface 1 is reduced.
When the pressure in the second decompression region 22 is equal to the pressure of the fluid surrounding the object surface 1, the ground pressure between the negative pressure seal member 6 and the object surface 1 increases. The frictional force between the negative pressure seal member 6 and the object surface 1 is increased, and the traveling function of the device is hindered due to the increased frictional force. The contents of inhibition will be described in detail.

In FIG. 3, when the electric motor 14 with a speed reducer is operated and the two drive wheels 11 are rotationally driven in the same direction, the apparatus goes straight (up or down) along the object surface 1.
When the two drive wheels 11 are driven to rotate in the opposite directions, the device turns (turns left or turns right).
In FIG. 1, in a state where the apparatus is adsorbing negative pressure to the object surface 1, the left-side electric motor 14 with a reduction gear and the right-side electric motor 14 with a reduction gear are counterclockwise as viewed from the left in FIG.

吸着状態において減速機付エアモータ8を付勢すると、負圧シール部材6と物体表面1との間の摩擦力が駆動車輪11と物体表面1との間の摩擦力がより大きい故に、装置本体2は回転すること無く、回転体5、負圧シール部材6及び補助シール部材7が所要の通り回転する。
かくすると、負圧シール部材6の延長部604に装着された研磨部材などの物体表面1を清掃するための材料605が物体表面1に接触しながら回転し、かかる清掃材料の作用によって物体表面1がクリーニングされる。
また研磨部材などの清掃材料と物体表面1との間の僅かな隙間を通して外部の流体が第1の減圧空間に流入する故に、かかる流体の流れによってクリーニング時に発生する粉塵等を第1の減圧空間の内部に吸引回収することができる。
When the air motor 8 with a speed reducer is energized in the suction state, the friction force between the negative pressure seal member 6 and the object surface 1 is larger than the friction force between the drive wheel 11 and the object surface 1. Without rotating, the rotating body 5, the negative pressure seal member 6 and the auxiliary seal member 7 rotate as required.
Thus, the material 605 for cleaning the object surface 1 such as an abrasive member attached to the extension 604 of the negative pressure seal member 6 rotates while contacting the object surface 1, and the object surface 1 is acted on by the action of the cleaning material. Is cleaned.
Further, since an external fluid flows into the first reduced pressure space through a slight gap between the cleaning material such as an abrasive member and the object surface 1, dust generated during cleaning by the flow of the fluid is removed from the first reduced pressure space. Can be collected by suction.
第2の減圧領域22の圧力が物体表面1を包囲する流体の圧力と同等であった場合においては、負圧シール部材6と物体表面1との接地圧力が増大するので、而して負圧シール部材6と物体表面1との間の摩擦力が増大され、該摩擦力の増大に起因して装置の走行機能が阻害されるが、図1を参照しながら以下に説明する。
即ち、装置の走行方向を変える手段として上述の如く2つの手段があるが、先ず、2式の駆動車輪11を互いに逆方向に回転駆動させて装置をその場で旋回させる手段を使用する場合において、
負圧シール部材6が例えば時計方向に回転している時において、装置本体2に対して反時計方向に回転させようとするトルクが該摩擦力の増大に起因して強く作用するので、装置は時計方向に旋回するのが大変困難となる。
次に、2式の駆動車輪11を同方向かつ回転速度を違えて回転駆動させて装置をカーブさせる手段を使用する場合において、
負圧シール部材6が例えば時計方向に回転している時において、装置本体2に対して反時計方向に回転させようとするトルクが該摩擦力の増大に起因して強く作用するので、装置は走行方向に向かって右方向にカーブしながら走行するのが大変困難となる。
When the pressure in the second decompression region 22 is equal to the pressure of the fluid surrounding the object surface 1, the ground pressure between the negative pressure seal member 6 and the object surface 1 increases, and thus the negative pressure The frictional force between the seal member 6 and the object surface 1 is increased, and the traveling function of the apparatus is hindered due to the increase in the frictional force, which will be described below with reference to FIG.
That is, there are two means as described above as means for changing the traveling direction of the apparatus. First, in the case of using means for rotating the two driving wheels 11 in opposite directions to turn the apparatus on the spot. ,
For example, when the negative pressure seal member 6 is rotating in the clockwise direction, the torque to be rotated in the counterclockwise direction with respect to the apparatus main body 2 acts strongly due to the increase in the frictional force. It becomes very difficult to turn clockwise.
Next, in the case of using means for driving the two driving wheels 11 in the same direction and rotating at different rotational speeds to curve the device,
For example, when the negative pressure seal member 6 is rotating in the clockwise direction, the torque to be rotated in the counterclockwise direction with respect to the apparatus main body 2 acts strongly due to the increase in the frictional force. It becomes very difficult to travel while turning rightward in the direction of travel.
上記に記述のように、第2の減圧領域22の圧力が物体表面1を包囲する流体の圧力と同等であった場合においては、負圧シール部材6と物体表面1との接地圧力が増大するので、而して負圧シール部材6と物体表面1との間の摩擦力が増大され、該摩擦力の増大に起因して装置の走行機能が阻害される。
しかしながら、第1の発明の装置において、第2の減圧領域22の圧力が、物体表面1を包囲する流体の圧力よりも低い圧力に維持されると、負圧シール部材6と物体表面1との接地圧力が減少するので、而して負圧シール部材6と物体表面1との間の摩擦力が減少され、かくして該装置の走行機能が阻害されることを阻止できる。
As described above, when the pressure in the second decompression region 22 is equal to the pressure of the fluid surrounding the object surface 1, the ground pressure between the negative pressure seal member 6 and the object surface 1 increases. Therefore, the frictional force between the negative pressure sealing member 6 and the object surface 1 is increased, and the running function of the apparatus is hindered due to the increase in the frictional force.
However, in the apparatus of the first invention, if the pressure in the second decompression region 22 is maintained at a pressure lower than the pressure of the fluid surrounding the object surface 1, the negative pressure sealing member 6 and the object surface 1 Since the ground contact pressure is reduced, the frictional force between the negative pressure seal member 6 and the object surface 1 is thus reduced, and thus it is possible to prevent the running function of the apparatus from being hindered.
上記に記述のように、第2の減圧領域22の圧力が物体表面1を包囲する流体の圧力と同等であった場合においては、負圧シール部材6と物体表面1との接地圧力が増大するので、而して負圧シール部材6と物体表面1との間の摩擦力が増大され、該摩擦力の増大に起因して装置の走行機能が阻害される。
しかしながら、第2の発明の装置をその場で旋回させる場合において、該旋回させたい方向と反対方向に負圧シール部材6が回転駆動するように構成すれば、該装置の走行機能すなわち旋回機能が阻害されることはない。
また、第2の発明の装置をカーブ走行させる場合において、該装置の走行方向に向かって左方向にカーブさせる場合には、図1において負圧シール部材6を時計方向に回転駆動させ、該装置の走行方向に向かって右方向にカーブさせる場合には、図1において負圧シール部材6を反時計方向に回転駆動させるように構成すれば、該装置の走行機能すなわちカーブ走行機能が阻害されることはない。
As described above, when the pressure in the second decompression region 22 is equal to the pressure of the fluid surrounding the object surface 1, the ground pressure between the negative pressure seal member 6 and the object surface 1 increases. Therefore, the frictional force between the negative pressure sealing member 6 and the object surface 1 is increased, and the running function of the apparatus is hindered due to the increase in the frictional force.
However, when the apparatus of the second invention is swung on the spot, if the negative pressure seal member 6 is rotationally driven in a direction opposite to the direction in which the apparatus is desired to swivel, the traveling function of the apparatus, that is, the swiveling function is achieved. There is no inhibition.
Further, when the apparatus of the second invention is curved, when the apparatus is curved leftward in the traveling direction of the apparatus, the negative pressure seal member 6 is driven to rotate clockwise in FIG. In the case where the vehicle is curved in the right direction toward the traveling direction, the traveling function of the device, that is, the curved traveling function is hindered if the negative pressure sealing member 6 is configured to rotate counterclockwise in FIG. There is nothing.
