Description

【0001】
【発明の属する技術分野】
本発明は、建屋、大型タンク等の外壁や内壁或いは天井等(以下、「壁面等」という)に真空吸着して走行する装置の吸着盤に関するものである。壁面等が平滑でなく、表面が粗い面であったり、凹凸面であっても、吸着盤内の真空圧を維持し、吸着盤の端縁が凹凸面の形状に追従し、壁面等によく吸着して、スムーズに走行することができる真空吸着走行装置の吸着盤に関するものである。
【0002】
【従来の技術】
従来の吸着盤の材質はゴム製が一般的である。そして吸着対象となる壁面等に吸着盤を密着させて吸着盤内の真空圧を維持している。しかしこのようなゴム製の吸着盤を使用した場合、次のような問題が生じた。
▲1▼低硬度ゴム製の吸着盤では、壁面等によく密着するので、リーク量は少ないが、摩耗が激しく、かつ接地摩擦が大きい。従って吸着力は大きくなるがその反面、装置の壁面等での上昇力は弱くなる。
▲2▼高硬度ゴム製の吸着盤では、耐摩耗性が高く、接地摩擦は少ないが、壁面等の凹凸に追従しにくい。従ってリーク量が多くなり、このためリークを補うため大風量の真空源が必要となる。
▲3▼回転式の吸盤では、路面の凹凸や、粗さの影響を低減させるために、クローラ等に複数個の小型吸着盤を取付け、吸盤が直接走行面と擦れないようになっている。しかしこれは回転部に吸着盤を複数個配置するため機構の複雑化は避けられない。
▲4▼その他の問題点
壁面等がゴム製の場合、このゴム製の壁面等に吸着盤で吸着しつつ真空吸着装置が自走すると、吸着盤と走行面との接触により擦れ、走行壁面に跡が残る。
▲5▼又、織成布積層吸着盤もしられている。これはポリミイド繊維、炭素繊維等を用いて積層化しているが、製法が特殊で高価とならざるを得ない(例えば、特許文献1参照。)。
以上のようなゴム製吸着盤や織成布積層吸着盤の諸問題に対処するため、ブラシ式シール手段もしられている(例えば、特許文献2参照。)。これは、回転部材と共に回転して壁面に接するようにして、走行抵抗を減ずるようになっている。

【発明が解決しようとする課題】
従来型のゴム製吸着盤や織成布製の吸着盤あるいは回転部材と共に回転するブラシ式の吸着盤においては、乾いた走行面を走行する際、非常に摩擦係数が大きかった。このため走行系の車輪やクローラの駆動力を高めなくてはならなかった。
【0005】
又粗くて凹凸のある走行面では、吸着盤からのリークが多量に発生するので、このリーク量を上回る強力な真空源を必要とした。
【0006】
本発明はこのような従来技術の問題点に鑑み、リーク量が少なく、小型の真空発生源で間に合い、しかも装置本体に真空発生用のブロアーを走行装置本体上に搭載しうる真空吸着走行装置用の吸着盤、詳しくはブラシ型の吸着盤を提供することを課題とする。
【0007】
【課題を解決するための手段】
(1)高密度の極細ブラシ毛でリング状に形成した。
(2)前記高密度・極細ブラシ毛の材料をナイロンもしくはポリプロビレンとした。
(3)前記高密度・極細ブラシ毛の線径は0.08〜0.3mmと極めて細いものとした。
(4)前記吸着盤は、高密度・極細ブラシ毛を鋼線のまわりに180°折り返し、折り返し部をリング状のC型チャンネルに挿入した後、C型チャンネルを側面から圧着して、カシメ、固定したものである。
(5)前記高密度の極細ブラシ毛を固着するC型チャンネルはブラシベースに固定され、このベースプレートを吸着盤リングに着脱可能に取付けて使用するようにした。
(6)前記ベースプレートを取付けた吸着盤リングは真空吸着走行装置の本体に対し摺動可能に装着され、壁面への吸着時吸着盤リングを吸着壁面に向って吸着盤押圧スプリングで付勢し、吸着盤と壁面等との密着性を良好にした。
(7)前記吸着盤リングは真空吸着装置本体との摺動部を円筒状シールゴム又はOリングで覆ってシールを完璧にした。
(8)壁面等の凹凸部を走行する時に真空圧の維持をするため、吸着盤を同心円状に内・外2重に配設した。
(9)内外2重に配設した吸着盤の内側吸着盤のブラシ毛の長さを、外側吸着盤のブラシ毛の長さより長くし、凹凸面に追従し易くした。
【0008】
【発明の実施の形態】
図に基いて説明する。図1はブロア搭載型でブラシ型の吸着盤を備えた吸着走行装置の側面図である。
【0009】
図1で1は吸着走行装置本体(以下、本体という)で、真空発生用の真空ブロア2を搭載している。本体1の壁面W等と接する側(図1の右側)に本発明に係るブラシ型の吸着盤3が取付けられている。本体1の上部(図1の左側)は本体カバー4で覆われている。
【0010】
ブラシ型の吸着盤3は、壁面等Wの凹凸に追従できるよう、吸着盤押圧スプリング5によって吸着時壁面等の走行面に向って(図1の右側に向って)付勢されている。
【0011】
6はクローラ又は車輪で、走行用モータ7で駆動される。8はフィルタで、このフィルタを介し外気は吸引される。9は吸着盤シールゴムで、吸着盤は壁面等Wに凹凸があっても吸着盤内の真空度を保持する為、本体に対し摺動するが、この時この吸着盤シールゴム9によって摺動部をシールし、洩れを防止している。
【0012】
吸着盤シールゴム9は図2の如くOリング10あるいは、図3の如く円筒状をなすゴム板10′でもよい。
【0013】
ブラシ型の吸着盤3は、ベースプレート11(図2)に溶接等で取付けられ、このベースプレート11が吸着盤リング12の取付部12aにねじ13で着脱可能に取り付けられる。吸着盤リング12の摺動部12bは本体1に取付けたブラシ型吸着盤保持部14に対し吸着盤シールゴム9でシールされて摺動する。図2では吸着盤シールゴムはOリングである。
【0014】
ブラシ型吸着盤保持部14は、本体1にねじ15で取付けられている。保持部14の端にはリングストッパを兼ねるフィルタ押え板17がねじ16で取り付けられている。
【0015】
真空ブロア2で吸引するとエアは、フィルタ8を介して吸引され(図2矢印A参照)、ブロア排気口18から排出される。19はパッキンゴムである。
【0016】
吸着盤押圧スプリング5は本体1に取付けられたスプリングケース20内に装着され、先端の吸着盤リング12を押圧するロッド21を介して吸着盤リング12の吸着盤リング取付部12bの上面に押圧力を付与する。22はインデックスプランジャーで、これにより押圧力の調節を行う。
【0017】
23は旋回式吊具で(図1)、この吊具23を介し、ロープRで吊り下げ吸着走行装置が壁面等Wから落下するのを防止している。吊具23は本体1に対しその基部が軸11のまわりに回転可能とし、真空吸着走行装置が方向変換しても、これに対処できるようになっている。
【0018】
図4にブラシ型の吸着盤3の拡大図を示す。24は高密度・極細ブラシ毛で、その線径は0.08〜0.3mmと極めて細く、材料はナイロンもしくはポリプロピレンである。
【0019】
高密度・極細ブラシ毛24は鋼線25を中心にU字形に180°折り曲げられ、その折り曲げ部をC型チャンネル26内に納め、C型チャンネル25を両側から図2の矢印方向にカシメて一体化している。
【0020】
ブラシ型の吸着盤3は、ベースプレート11に対し図5の如く1重、または図6の如く2重に設けて真空度の保持を完璧にしている。図6の場合には、外側の吸着盤のブラシ毛の長さが内側の吸着盤のブラシ毛より短くなっている。
【0021】
図7はブラシ型の吸着盤の走行時における状態を示し、図7・aは吸着前、図7・bは平滑壁面等への吸着時、図7・cは凸状壁面走行時、図7・dは凹状壁面走行時の状態を示す。図7・cに示すように凸状面では短尺のブラシ型吸着盤が、又図7・dの如く凹状面では長尺のブラシ型吸着盤が接し、真空洩れを防いでいる。
【0022】
以上のような構成であって、真空ブロア2を起動させブラシ型の吸着盤3内を負圧にすると、吸着盤3は走行面に吸着する。真空圧がさらに上昇すると吸着盤押付用スプリング5が縮み、ブラシ毛がたわむことにより、吸着盤3は真空ブロア2の方向に引き込まれ吸着盤押圧スプリング5のバネ力でクローラ及び車輪6に押付力が与えられ、壁面や天井に吸着走行することができる。
なお、図1は真空ブロア2を搭載した装置であるが、大型の走行装置では、真空ブロアを本体外に配置し、吸着盤3と真空ブロアをサクションホースで繋ぐものもできる。
【0023】
又ブラシは、ナイロンもしくは、ポリプロピレン製のものを用い、線径は、走行面の凹凸に応じてφ0.08〜φ0.3の中から選定し、凹凸の大きさに応じてブラシ毛の長さを変更する。
ブラシ線径は、細くすればブラシの毛密度が密になるのでリーク量が減少し、真空圧が高くなるが、ブラシの腰が弱くなり、毛足を短くしなくてはならない。
【0024】
さらに図5の1重のブラシ型吸着盤は、比較的滑らかな走行面に用い、線径φ0.08、ブラシ長さ20〜25mmが最適であった。
図6の2重ブラシ型吸着盤は、凹凸がある走行面に用いるもので、ブラシが凹凸面との間の隙間を埋め真空圧を維持できる。この場合、外側のブラシで線径φ0.08、ブラシ長さ20〜25mm内側のブラシが線径φ0.08、ブラシ長さ30〜40mmが最適であった。この2重ブラシを用いた場合、凹部で幅20mm深さ10mmの窪みまで対応でき、凸部は段差高さ10mm吸着盤内真空圧を維持し吸着走行することが可能であった。また、ブラシ数は、走行面の状態に合わせ、さらに2段さらにはそれ以上の多段にすることができる。
【0025】
【発明の効果】
▲1▼ブラシ型吸着盤には、高密度極細ブラシ毛を用いた。そしてこれを金属線たとえば(鋼線)に折り返して巻きつけC型チャンネルに押し込んだ後C型チャンネル側面を圧着カシメればよいので、製作が極めて容易である。
▲2▼リング状に成型したブラシ型の吸着盤は、走行面の粗さ、凹凸の度合いに応じてブラシの線径、ブラシ毛長さ、ブラシ密度及び、ブラシリング数を多段化し、最適な状態に変更でき、便利である。
▲3▼粗い壁面では小さな凹凸があり、従来の吸着盤だとリーク量が多くなり吸着することができないが、高密度極細ブラシ毛を用いることで壁面等の凹凸にブラシ毛が追従し、吸着盤リーク量を低減するので、吸着盤内の真空圧を保持できる。
▲4▼ブラシ型の吸着盤を用いたことにより、粗い壁面等と吸着盤を構成するブラシ間の摩擦係数が小さいので、本体の吸着上昇力が大きくなる。
▲5▼ゴム製吸着盤と比べ耐摩耗性に優れ、吸着盤の交換頻度を低減できる。
▲6▼ブラシを吸着盤にしているので、吸着走行した箇所を清掃できる。このため、検査器機器を搭載して、対称面の検査を行う場合にはブラシでまず清掃し、清掃面を本体搭載の真空ブロアで吸引したのちに、検査を行うことができる。このように、清掃と検査等を同一の装置で行うことができるので作業効率上極めて便利である。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a suction disk of a device that travels by vacuum suction on an outer wall, an inner wall, a ceiling, or the like (hereinafter, referred to as a “wall surface or the like”) of a building, a large tank, or the like. Even if the wall surface is not smooth and the surface is rough or uneven, the vacuum pressure in the suction cup is maintained, and the edge of the suction cup follows the shape of the uneven surface, and is well-formed on the wall. The present invention relates to a suction board of a vacuum suction running device capable of sucking and running smoothly.
[0002]
[Prior art]
The material of the conventional suction cup is generally made of rubber. Then, the suction disk is brought into close contact with a wall surface or the like to be suctioned to maintain the vacuum pressure in the suction disk. However, when such a rubber suction cup is used, the following problem occurs.
{Circle around (1)} The suction pad made of low-hardness rubber adheres well to the wall surface and the like, so that the leak amount is small, but the wear is severe and the ground friction is large. Accordingly, the suction force is increased, but the lifting force on the wall surface of the apparatus is weakened.
{Circle around (2)} A suction pad made of high-hardness rubber has high wear resistance and little ground friction, but does not easily follow irregularities on a wall surface or the like. Therefore, the amount of leak increases, and a vacuum source with a large air volume is required to compensate for the leak.
(3) In the rotary suction cup, a plurality of small suction cups are mounted on a crawler or the like so as to reduce the influence of road surface unevenness and roughness, so that the suction cup does not directly rub against the running surface. However, in this case, a plurality of suction disks are arranged in the rotating section, so that the mechanism is inevitably complicated.
(4) Other problems When the wall surface is made of rubber and the vacuum suction device is self-propelled while adsorbing to the rubber wall surface by the suction plate, the suction device is rubbed by the contact between the suction plate and the running surface, and the running wall surface is rubbed. Traces remain.
{Circle around (5)} Also, a woven cloth laminated suction disk is used. Although this is laminated using polyimide fibers, carbon fibers, and the like, the production method is special and inevitably expensive (see, for example, Patent Document 1).
To cope with the various problems of the rubber suction disk and the woven cloth laminated suction disk as described above, a brush-type sealing means is also used (for example, see Patent Document 2). This reduces the running resistance by rotating together with the rotating member so as to contact the wall surface.
[0003]
[Patent Document 1]
JP-B-63-63924 [Patent Document 2]
JP-A-6-71378 [0004]
[Problems to be solved by the invention]
In a conventional rubber suction disk, a woven cloth suction disk, or a brush-type suction disk that rotates together with a rotating member, the coefficient of friction is extremely large when running on a dry running surface. For this reason, the driving force of the wheels and crawlers of the traveling system had to be increased.
[0005]
On the rough and uneven running surface, a large amount of leakage from the suction disk occurs, so a powerful vacuum source exceeding the amount of leakage was required.
[0006]
SUMMARY OF THE INVENTION The present invention has been made in view of the problems of the prior art described above, and has a small amount of leakage, can be used with a small vacuum generating source, and can be mounted on a main body of a traveling device. It is an object of the present invention to provide a suction cup, more specifically, a brush-type suction cup.
[0007]
[Means for Solving the Problems]
(1) A ring was formed with high-density ultra-fine brush bristles.
(2) The material of the high-density / ultra-fine brush bristles is nylon or polypropylene.
(3) The wire diameter of the high-density and extra-fine brush bristles was extremely thin, 0.08 to 0.3 mm.
(4) The suction disk is formed by folding high-density / ultra-fine brush bristles 180 degrees around a steel wire, inserting the folded portion into a ring-shaped C-shaped channel, and then pressing the C-shaped channel from the side to form a crimping device. It is fixed.
(5) The C-shaped channel to which the high-density ultrafine brush bristles are fixed is fixed to a brush base, and this base plate is detachably attached to a suction cup ring for use.
(6) The suction cup ring to which the base plate is attached is slidably mounted on the main body of the vacuum suction traveling device, and urges the suction cup ring toward the suction wall by a suction cup pressing spring when adsorbing to the wall surface. The adhesion between the suction plate and the wall surface was improved.
(7) In the suction cup ring, a sliding portion with the main body of the vacuum suction device is covered with a cylindrical sealing rubber or an O-ring to complete the seal.
(8) In order to maintain the vacuum pressure when traveling on the uneven portion such as the wall surface, the suction cups are arranged concentrically inside and outside.
(9) The length of the bristles of the inner suction disk of the suction disks arranged in two layers inside and outside is made longer than the length of the brush hairs of the outer suction disk to make it easier to follow the uneven surface.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
This will be described with reference to the drawings. FIG. 1 is a side view of a suction traveling device equipped with a brush-type suction disk mounted on a blower.
[0009]
In FIG. 1, reference numeral 1 denotes a suction traveling device main body (hereinafter, referred to as a main body) on which a vacuum blower 2 for generating vacuum is mounted. A brush-type suction plate 3 according to the present invention is attached to a side (right side in FIG. 1) of the main body 1 that contacts the wall surface W or the like. The upper part of the main body 1 (the left side in FIG. 1) is covered with a main body cover 4.
[0010]
The brush-type suction disk 3 is urged toward the running surface such as the wall surface during suction (toward the right side in FIG. 1) by the suction disk pressing spring 5 so as to follow the irregularities of the wall surface W or the like.
[0011]
A crawler or wheel 6 is driven by a traveling motor 7. Reference numeral 8 denotes a filter through which outside air is sucked. Reference numeral 9 denotes a suction cup seal rubber. The suction disc slides with respect to the main body in order to maintain the degree of vacuum in the suction cup even if the wall surface or the like has irregularities. Sealed to prevent leakage.
[0012]
The adsorber seal rubber 9 may be an O-ring 10 as shown in FIG. 2 or a cylindrical rubber plate 10 'as shown in FIG.
[0013]
The brush type suction plate 3 is attached to a base plate 11 (FIG. 2) by welding or the like, and the base plate 11 is detachably mounted to a mounting portion 12a of the suction plate ring 12 with screws 13. The sliding portion 12b of the suction ring 12 slides on the brush-type suction disk holding portion 14 attached to the main body 1 while being sealed with the suction disk sealing rubber 9. In FIG. 2, the sealer seal rubber is an O-ring.
[0014]
The brush-type suction disk holder 14 is attached to the main body 1 with screws 15. A filter holding plate 17 also serving as a ring stopper is attached to an end of the holding portion 14 with a screw 16.
[0015]
When sucked by the vacuum blower 2, the air is sucked through the filter 8 (see the arrow A in FIG. 2) and is discharged from the blower exhaust port 18. 19 is a packing rubber.
[0016]
The suction cup pressing spring 5 is mounted in a spring case 20 attached to the main body 1, and is pressed against the upper surface of the suction cup ring mounting portion 12 b of the suction cup ring 12 via a rod 21 that presses the suction cup ring 12 at the tip. Is given. An index plunger 22 adjusts the pressing force.
[0017]
Numeral 23 denotes a swing type suspending device (FIG. 1), through which the suction traveling device suspended by a rope R is prevented from dropping from a wall surface W or the like. The base of the hanger 23 is rotatable around the shaft 11 with respect to the main body 1 so that even if the vacuum suction traveling device changes direction, this can be dealt with.
[0018]
FIG. 4 shows an enlarged view of the brush type suction plate 3. Reference numeral 24 denotes high-density and ultra-fine brush bristles having an extremely thin wire diameter of 0.08 to 0.3 mm, and is made of nylon or polypropylene.
[0019]
The high-density and extra-fine brush bristles 24 are bent 180 degrees in a U-shape around a steel wire 25, and the bent portion is accommodated in a C-shaped channel 26, and the C-shaped channel 25 is crimped from both sides in the direction of the arrow in FIG. Is becoming
[0020]
The brush-type suction plate 3 is provided as a single layer as shown in FIG. 5 or a double layer as shown in FIG. 6 with respect to the base plate 11 to perfectly maintain the degree of vacuum. In the case of FIG. 6, the length of the bristles of the outer suction plate is shorter than that of the inner suction plate.
[0021]
7A and 7B show a state in which the brush-type suction disk is traveling, FIG. 7A is a state before suction, FIG. 7B is a state in which suction is performed on a smooth wall surface, and FIG. D indicates the state when traveling on the concave wall surface. As shown in FIG. 7C, a short brush-type suction disk is in contact with the convex surface, and a long brush-type suction disk is in contact with the concave surface as shown in FIG. 7D, thereby preventing vacuum leakage.
[0022]
With the above configuration, when the vacuum blower 2 is activated and the inside of the brush type suction plate 3 is made to have a negative pressure, the suction plate 3 is sucked on the running surface. When the vacuum pressure further rises, the suction plate pressing spring 5 contracts, and the brush hairs are bent, so that the suction plate 3 is drawn in the direction of the vacuum blower 2 and the pressing force of the suction plate pressing spring 5 is applied to the crawler and the wheel 6. And can be adsorbed on a wall or ceiling.
Although FIG. 1 shows the apparatus equipped with the vacuum blower 2, in a large traveling apparatus, the vacuum blower may be arranged outside the main body, and the suction board 3 and the vacuum blower may be connected by a suction hose.
[0023]
The brush is made of nylon or polypropylene, and the wire diameter is selected from φ0.08 to φ0.3 according to the unevenness of the running surface. To change.
If the brush wire diameter is made thinner, the bristle density of the brush becomes denser, so that the amount of leakage is reduced and the vacuum pressure is increased, but the stiffness of the brush is weakened and the bristle feet must be shortened.
[0024]
Further, the single brush type suction cup shown in FIG. 5 was used for a relatively smooth running surface, and a wire diameter φ of 0.08 and a brush length of 20 to 25 mm were optimal.
The double brush type suction disk shown in FIG. 6 is used for a running surface having unevenness, and a brush can fill a gap between the uneven surface and the vacuum and maintain a vacuum pressure. In this case, the optimum diameter of the outer brush was 0.08 and the inner brush diameter was 20 to 25 mm. The optimum diameter of the inner brush was 0.08 and the brush length was 30 to 40 mm. In the case of using this double brush, it was possible to cope with a concave portion having a width of 20 mm and a depth of 10 mm, and the convex portion was able to perform suction traveling while maintaining the vacuum pressure in the suction plate at a step height of 10 mm. In addition, the number of brushes can be two or more or more in accordance with the state of the running surface.
[0025]
【The invention's effect】
{Circle around (1)} High-density ultrafine brush bristles were used for the brush type suction disk. Then, this is folded over a metal wire such as a (steel wire), wound around and pushed into the C-shaped channel, and then the side surface of the C-shaped channel may be crimped.
(2) The brush-type suction cup molded into a ring shape has multiple stages of brush wire diameter, brush bristle length, brush density, and number of brush rings according to the roughness of the running surface and the degree of unevenness. It can be changed to a state and is convenient.
(3) There are small irregularities on the rough wall surface, and with the conventional suction cups, the amount of leakage is too large to adsorb. However, the use of high-density ultra-fine brush bristles allows the brush hairs to follow the irregularities on the wall surface, etc. Since the board leakage is reduced, the vacuum pressure in the suction board can be maintained.
{Circle around (4)} Since the brush-type suction disk is used, the coefficient of friction between the rough wall surface and the brushes constituting the suction disk is small, so that the suction lifting force of the main body is increased.
{Circle around (5)} Compared with a rubber suction disk, it has excellent wear resistance and can reduce the frequency of replacement of the suction disk.
{Circle around (6)} Since the brush is used as the suction disk, the portion where the suction travel has been performed can be cleaned. For this reason, when the inspection device is mounted and the inspection of the symmetry plane is performed, the inspection can be performed after first cleaning with a brush, suctioning the cleaning surface with a vacuum blower mounted on the main body. As described above, cleaning and inspection can be performed by the same apparatus, which is extremely convenient in terms of work efficiency.
