Description

本発明は永久磁石を利用した走行装置に係わり、詳しくはカメラや搬送具又は加工装置等、各種搬送物を装着して建築物内外や、例えば設備として炉内等を各方向に走行することができる装置の改良に関するものである。   The present invention relates to a traveling device using a permanent magnet, and more specifically, it is possible to travel in and out of a building, for example, as a facility, in a furnace or the like by mounting various transported objects such as a camera, a transporting tool, or a processing device. The present invention relates to an improvement of a device that can be used.

周知の通り、永久磁石を利用した走行装置は公知である。例えば、特許文献1にみられる。即ち、透明管又は透明窓部を有する管により構成されたガイド管と、該ガイド管内を流体圧により圧送されるピグと、該ピグに搭載された撮像装置とを備え、該撮像装置が上記ガイド管の透明な管壁又は透明窓部を通してガイド管の外側を撮像できるようにし、筒内側にガイド管外面を清掃するための清掃手段を有するガイド管清掃筒を、ガイド管外側に管長手方向移動可能に外装し、該ガイド管清掃筒をガイド管壁を挟んでピグに磁気吸着させることで、ピグを随伴して移動できるようにしたものがある。   As is well known, traveling devices using permanent magnets are known. For example, it can be seen in Patent Document 1. That is, a guide tube composed of a transparent tube or a tube having a transparent window portion, a pig that is pumped by fluid pressure in the guide tube, and an imaging device mounted on the pig, the imaging device including the guide The guide tube cleaning cylinder, which has a cleaning means for cleaning the outer surface of the guide tube inside the tube so that the outside of the guide tube can be imaged through the transparent tube wall or transparent window portion of the tube, is moved to the outside of the guide tube in the longitudinal direction. In some cases, the guide tube cleaning cylinder can be moved along with the pig by magnetically attracting the guide tube cleaning cylinder to the pig across the guide tube wall.

特開2005−210682JP2005-210682

上記従来技術の場合、流体圧によって走行する方の走行体であるピグ内の永久磁石と磁気吸着により同伴する方の走行体であるガイド管清掃筒内の永久磁石とは、互いに磁気吸着結合関係の対配置になっているから、ピグの走行に対してガイド管清掃筒を磁気吸着して同伴する構造となっているものである。然しながらピグ内の永久磁石に対して、磁気吸着により同伴するガイド管清掃筒内の永久磁石とは、上記のように1対1で磁気吸着結合関係の対配置になっているのみである。   In the case of the above prior art, the permanent magnet in the pig, which is the traveling body traveling by the fluid pressure, and the permanent magnet in the guide tube cleaning cylinder, which is the traveling body accompanied by magnetic attraction, are magnetically coupled to each other. Therefore, the guide tube cleaning cylinder is magnetically adsorbed with the traveling of the pig. However, the permanent magnets in the guide tube cleaning cylinder that are accompanied by magnetic attraction with respect to the permanent magnets in the pig are only in a one-to-one paired arrangement of magnetic attraction coupling as described above.

従って、上記ガイド管清掃筒は、ピグが走行を開始し又は停止した時に磁気吸着関係にある対の磁石によって磁気吸着されて移動しようとするが、上記ガイド管清掃筒は、ガイド管清掃筒がその慣性力によってピグの移動に対し直に同伴移動せずに、そのまま元の位置に取り残されて互いの位置がズレる場合がある。この結果、上記ガイド管清掃筒は、その後の流体圧によるピグの走行に対して同伴走行しなくなり、走行装置全体の走行性能が低下する。
とりわけ、磁気吸着結合によって同伴走行する走行体に大きな慣性力が生じたり、流体圧によって走行する走行体が急発進、停止する場合に上記のような不具合がより顕著になる。
Therefore, the guide tube cleaning cylinder is moved by being magnetically attracted by a pair of magnets having a magnetic attraction relationship when the pig starts or stops traveling. In some cases, the inertial force does not move directly with respect to the movement of the pig, but is left in the original position as it is, and the positions of each other shift. As a result, the guide tube cleaning cylinder does not travel with the subsequent traveling of the pig due to fluid pressure, and the traveling performance of the entire traveling device is degraded.
In particular, the above-described problem becomes more noticeable when a large inertial force is generated in the traveling body that travels with the magnetic attraction coupling, or when the traveling body that travels due to fluid pressure suddenly starts and stops.

従って本発明の目的とするところは、駆動流体管内の左右内壁面に案内支持されて走行する管内走行体の左右車輪と、該管内走行体に磁気吸着により同期して上記駆動流体管の両外側面に案内支持されて走行する両管外走行体の車輪の負荷をバランスさせることで、上記管内走行体の車輪と両管外走行体の車輪の磨耗を軽減することができる永久磁石を利用した走行装置を提供するにある。   Accordingly, an object of the present invention is to provide the right and left wheels of the in-pipe running body that is guided and supported by the left and right inner wall surfaces in the drive fluid pipe, and both the outer sides of the drive fluid pipe in synchronism by magnetic adsorption to the in-pipe run body. By using a permanent magnet that can reduce the wear of the wheels of the in-pipe traveling body and the wheels of the both-outside traveling body by balancing the load of the wheels of both the outside traveling bodies that are guided and supported by the side surfaces. To provide a traveling device.

In order to achieve the above object, the present invention has the following technical means. In other words, using the reference numerals in the accompanying drawings corresponding to the embodiments, the traveling device using the permanent magnet according to claim 1 of the present invention is attached to the base (K) from one side to the other side. A driving fluid pipe (1) extending toward the inner side, and an in-pipe running body (9) guided by an inner wall surface (2) in the driving fluid pipe (1) and running from one side to the other side by fluid pressure. An outside-tube traveling body (29, 30) which is supported on the outer surface of the driving fluid pipe (1) and is equipped with a transported body (38) to follow the traveling of the in-tube traveling body (9). In addition, the main permanent magnet group (A) disposed in the in-pipe traveling body (9) and the out-of-tube travel so as to have a different polar relationship that attracts each magnetic pole of the main permanent magnet group (A). Running using permanent magnets composed of secondary permanent magnet groups (B1, B2) arranged in the body (29, 30) In the apparatus, the in-pipe running body (9) is guided and supported so as to be able to run while being supported on the upper and lower and left and right inner wall surfaces (2) in the driving fluid pipe (1) through wheels. Inside the in-pipe traveling body (9), a main permanent magnet group (A) composed of a plurality of permanent magnets orthogonal to the traveling direction is disposed, and the out-of-tube traveling body (29, 30) includes the driving fluid. The upper side of the pipe (1) is guided and supported so as to be able to travel from one side to the other side via wheels, and the driving fluid pipe (1) is connected to both outer sides of the driving fluid pipe (1) via wheels. The pair of traveling bodies (29, 30) are guided and supported so as to be capable of traveling along the connecting line (29), straddling the lower surface of the driving fluid pipe (1). Are integrally connected, and the transported body (38) is mounted on the lower surface of the connecting member (28). Secondary permanent magnet groups (B1, B2) composed of a plurality of permanent magnets orthogonal to the traveling direction are arranged so that the magnetic poles facing the magnetic poles of the main permanent magnet group (A) are in a different polarity relationship that attract each other. The main permanent magnet group (A) of the traveling body (9) in the pipe and the secondary permanent magnet groups (B1, B2) of the traveling body (29, 30) outside the pipe (9). A) or the secondary permanent magnet group (B1, B2) or the main permanent magnet group (A) at either end (V), (W) along the traveling direction of the secondary permanent magnet group (B1, B2). A traveling device using permanent magnets, characterized by providing repulsive permanent magnets (G1a, G1b, G2a, G2b) having the same polarity repelling each other with respect to the permanent magnets at both ends along the traveling direction of is there.
According to the traveling device using the permanent magnet, the in-pipe traveling body (9) travels from one side to the other side in the longitudinal direction in the driving fluid pipe (1) or from the other side to the one side. Since the secondary permanent magnet group (B1, B2) of the extra-tube traveling body (29, 30) is a pair of magnetic attraction coupling with respect to the main permanent magnet group (A) of the in-pipe traveling body (9), The extra-tube traveling bodies (29, 30) also travel in the same direction.
At this time, the driving fluid pipe is synchronized with the left and right wheels of the in-pipe running body (9) that is guided and supported by the left and right inner wall surfaces in the driving fluid pipe (1) and the in-pipe running body (9) by magnetic adsorption. The load on the wheels of the two extra-tube traveling bodies (29, 30) traveling while being guided and supported by both outer surfaces of (1) is balanced.
Moreover, the both ends (V) and (W) along the traveling direction of the main permanent magnet group (A) of the outside traveling body (29, 30) or the inside traveling body (9) in a magnetic attraction coupling pair relationship. Since permanent magnets having the same polarity repelling each other are provided with respect to the permanent magnets, when the in-pipe traveling body (9) travels in one direction, the out-of-tube traveling bodies (29, 30) repel each other with the permanent magnets at both ends. Since the permanent magnets are pushed in the same traveling direction by the repulsive forces of the permanent magnets, the extracorporeal traveling bodies (29, 30) are synchronized with the traveling of the in-pipe traveling body (9) even if an inertial force is generated during sudden start or stop. Then run.

請求項1に記載の発明によれば、駆動流体管内の左右内壁面に案内支持されて走行する管内走行体の左右車輪と、該管内走行体に磁気吸着により同期して上記駆動流体管の両外側面に案内支持されて走行する両管外走行体の車輪の負荷をバランスさせることで、上記管内走行体の車輪と両管外走行体の車輪や軌道面の磨耗を軽減することができる。これにより、管内走行体の車輪の寿命を延長することができ、管内走行体内の主永久磁石群と管外走行体内の従永久磁石群相互の吸着力を強力にすることが可能となり、管内走行体に対する管外走行体の追随走行性を向上することができる。   According to the first aspect of the present invention, the left and right wheels of the in-pipe running body that travels while being guided and supported by the left and right inner wall surfaces in the drive fluid pipe, and both the drive fluid pipes are synchronized with the in-pipe run body by magnetic adsorption. By balancing the loads of the wheels of both the outer traveling bodies that are guided and supported by the outer surface, it is possible to reduce wear of the wheels of the in-pipe traveling body, the wheels of the both outer traveling bodies, and the raceway surface. As a result, the service life of the wheels of the in-pipe traveling body can be extended, and the attractive force between the main permanent magnet group in the in-pipe traveling body and the secondary permanent magnet group in the out-of-pipe traveling body can be strengthened. The followability of the extracorporeal traveling body relative to the body can be improved.

Are arranged so as to correspond to each other in a different polarity relationship.

詳しくは、主永久磁石群Aは、管内走行体9の内部に走行方向と直交する方向に複数の棒状の永久磁石1M1,1M2,1M3が並設されて、隣接する永久磁石1M1,1M2,1M3両端の磁極N,Sが、走行方向交互に異極となるように配設されると共に、従永久磁石群B1,B2は、上記永久磁石1M1,1M2,1M3両端の各磁極N,Sに対し、互いに吸着し合う異極関係になるように磁極が対応する複数の永久磁石から成り、上記管外走行体29,30内に収容される従永久磁石群B1,B2の隣接する永久磁石が走行方向交互に異極となるように配設されている。   Specifically, the main permanent magnet group A includes a plurality of rod-like permanent magnets 1M1, 1M2, and 1M3 arranged in parallel in the direction perpendicular to the traveling direction inside the in-pipe traveling body 9, and adjacent permanent magnets 1M1, 1M2, and 1M3. The magnetic poles N and S at both ends are arranged so as to have different polarities alternately in the traveling direction, and the secondary permanent magnet groups B1 and B2 are arranged with respect to the magnetic poles N and S at both ends of the permanent magnets 1M1, 1M2, and 1M3. The permanent magnets adjacent to the sub-permanent magnet groups B1 and B2 that are composed of a plurality of permanent magnets corresponding to the magnetic poles so as to have different polarities attracting each other and accommodated in the extra-tube traveling bodies 29 and 30 run. They are arranged so that the directions are alternately different.

更に、本発明は上記の構成に於いて、更に一対の磁気吸着結合関係にある管内外の走行体9,29,30内の主永久磁石群Aと従永久磁石群B1,B2の内、何れか一方の主永久磁石群A又は従永久磁石群B1,B2の一方側から他方側に沿った端部V,Wに、何れか他方の従永久磁石群B1,B2又は主永久磁石群Aの走行方向に沿った端部V,Wの永久磁石に対して互いに反発する同極となる反発用永久磁石G1a,G1b及びG2a,G2bが設けられている。   Further, according to the present invention, in the above-described configuration, any one of the main permanent magnet group A and the secondary permanent magnet groups B1 and B2 in the traveling bodies 9, 29 and 30 inside and outside the pipe, which are in a pair of magnetic attraction and coupling relations. From one side of the main permanent magnet group A or the secondary permanent magnet group B1, B2 to the end portions V, W along the other side, either the secondary permanent magnet group B1, B2 or the primary permanent magnet group A Repulsive permanent magnets G1a, G1b and G2a, G2b having the same polarity repelling each other with respect to the permanent magnets at the ends V, W along the traveling direction are provided.

この図2に示す例では、管外走行体29,30の従永久磁石群B1,B2の一側端部Vには、互いに異極となるよう両端にS極、N極が形成された反発用の永久磁石G1a,G1bを隣接して配設し、他側端部Wには、両端に互いに異極となるS極、N極が配設された反発用の永久磁石G2a,G2bを隣接して配設した例を示してある。   In the example shown in FIG. 2, the repulsion in which the S and N poles are formed at both ends of the secondary permanent magnet groups B <b> 1 and B <b> 2 of the extra-runners 29 and 30 so as to be different from each other. Permanent magnets G1a and G1b are disposed adjacent to each other, and repulsive permanent magnets G2a and G2b each having opposite S and N poles disposed at both ends are adjacent to the other end W. An example of the arrangement is shown.

これらの反発用永久磁石G1a,G1b及びG2a,G2bは、管内走行体9の主永久磁石群Aの走行方向に沿った片側端部Vの永久磁石1M1のN極及びS極に対して反発するように同極が対応するように配設されている。   These repulsive permanent magnets G1a, G1b and G2a, G2b repel the N and S poles of the permanent magnet 1M1 at one end V along the traveling direction of the main permanent magnet group A of the in-pipe traveling body 9. Thus, the same poles are arranged so as to correspond.

これにより、管内走行体9が図2に於いてP方向(左側)に走行すると、理論的には管外走行体29,30も主永久磁石群Aと従永久磁石群B1,B2とが異極で対向する磁気吸着結合関係にあるのでP方向に同期して移動するが、実際には管外走行体29,30には慣性があるので、管内走行体9のP方向への移動に同期した移動ができなくなる。   As a result, when the in-pipe traveling body 9 travels in the direction P (left side) in FIG. 2, theoretically, the out-of-pipe traveling bodies 29 and 30 also differ from the main permanent magnet group A and the sub permanent magnet groups B1 and B2. Since it is in a magnetic adsorption coupling relationship facing each other at the poles, it moves in synchronism with the P direction. However, since the extra-tube traveling bodies 29 and 30 have inertia, they are synchronized with the movement of the in-pipe traveling body 9 in the P direction. Cannot be moved.

そこで、反発用永久磁石G1a,G1bが設けられていることから、管内走行体9の移動によって主永久磁石群Aの永久磁石1M1の左方向Pへの移動により、上記永久磁石1M1の磁極N又はS極に対し反発用永久磁石G1a,G1bの磁極が同極となるよう配設されることで、互いに反発して管外走行体29,30を左方向Pへ押すことになり、慣性があっても、管外走行体29,30のP方向への同期移動がより確実になる。   Therefore, since the permanent magnets G1a and G1b for repulsion are provided, the movement of the in-pipe traveling body 9 causes the movement of the permanent magnet 1M1 of the main permanent magnet group A in the left direction P, so that the magnetic pole N of the permanent magnet 1M1 or By arranging the repulsive permanent magnets G1a and G1b so that the magnetic poles of the repulsive permanent magnets G1a and G1b have the same polarity, the repulsive magnets 29 and 30 repel each other and push the left and right traveling bodies 29 and 30 in the left direction P. However, the synchronous movement of the extra-tube traveling bodies 29 and 30 in the P direction is more reliable.

同様に、管内走行体9が図1に示すQ方向に走行すると、管外走行体29,30も主永久磁石群Aと従永久磁石群B1,B2とが磁気吸着結合関係にあるのでQ方向に同期して移動することになるが、実際には管外走行体29,30には慣性があるので、管内走行体9のQ方向への移動に同期した移動ができなくなる。   Similarly, when the in-pipe traveling body 9 travels in the Q direction shown in FIG. 1, the out-of-pipe traveling bodies 29 and 30 are also in the Q direction because the main permanent magnet group A and the secondary permanent magnet groups B1 and B2 are in a magnetic attraction coupling relationship. However, since the out-of-pipe running bodies 29 and 30 have inertia, it is impossible to move in synchronism with the movement of the in-pipe running body 9 in the Q direction.

そこで、反発用磁石G2a,G2bが設けられているので、管内走行体9の移動により主永久磁石群Aの永久磁石1M3が右方向Qへ移動することにより、上記永久磁石1M3の磁極N又はS極に対し反発用磁石G2a,G2bの磁極が同極となるよう配設されることで、互いに反発して管外走行体29,30を右方向Qへ押すことになり、慣性があっても、管外走行体29,30のQ方向への同期移動がより確実になる。   Therefore, since the repulsion magnets G2a and G2b are provided, the permanent magnet 1M3 of the main permanent magnet group A is moved in the right direction Q by the movement of the in-pipe traveling body 9, whereby the magnetic pole N or S of the permanent magnet 1M3. By disposing the repulsion magnets G2a and G2b so that the magnetic poles thereof are the same as the poles, the repulsion magnets G2a and G2b are repelled from each other and push the out-of-tube traveling bodies 29 and 30 in the right direction Q. Further, the synchronous movement in the Q direction of the extra-tube traveling bodies 29 and 30 becomes more reliable.

上記の例では、主永久磁石群A又は従永久磁石群B1,B2を3つの永久磁石として示しているが、これら永久磁石の数は、管内外の走行体の大きさ、形状、速度、その他使用条件等様々な設計及び他の条件に応じて適宜増減しても良く、各単一の永久磁石の長さ、幅、厚さも適宜なものを選択することができる。   In the above example, the main permanent magnet group A or the secondary permanent magnet groups B1 and B2 are shown as three permanent magnets. The number of these permanent magnets is the size, shape, speed, etc. of the traveling body inside and outside the pipe. It may be appropriately increased or decreased according to various designs such as usage conditions and other conditions, and the length, width and thickness of each single permanent magnet can be appropriately selected.

更に、反発用永久磁石G1a,G1b及びG2a,G2bについても以上までの例では上方の管外走行体29,30の従永久磁石群B1,B2の端部V,Wにそれぞれ隣接して設ける例を示したが、流体圧力によって駆動される管内走行体9の主永久磁石群A一側端部Vと他側端部Wに隣接して、管外走行体29,30の従永久磁石群B1,B2の一方及び他方端部の永久磁石に対して反発する為の反発用磁石を各々設けても良い。   Further, the repulsive permanent magnets G1a, G1b and G2a, G2b are also provided adjacent to the end portions V, W of the secondary permanent magnet groups B1, B2 of the upper extra-tube traveling bodies 29, 30 in the above examples. Although the main permanent magnet group A of the in-pipe running body 9 driven by the fluid pressure is adjacent to the one end V and the other end W of the in-pipe running body 9, the secondary permanent magnet group B1 of the extra-tube running bodies 29 and 30 is shown. , B2 may be provided with repulsion magnets for repelling the permanent magnets at one and the other end of B2.

以上述べた、各永久磁石の1つ1つは、希土類の材料より成る永久磁石が望ましい。例えばネオジウム・鉄・ボロンを原料とする磁石やサマリウム・コバルトを原料とする磁石等であり、これらの永久磁石は、管内外の走行体9及び29、30に接着剤接合されるか、図示せざるも任意の取付手段を介してしっかりと固定される。又上記実施例では、管内外の走行体9及び29,30は、水平状態で走行する例を示してあるが、垂直走行、斜行走行、カーブ走行等するものである。   Each of the permanent magnets described above is preferably a permanent magnet made of a rare earth material. For example, magnets made from neodymium, iron, and boron, magnets made from samarium and cobalt, etc., and these permanent magnets may be adhesively bonded to the running bodies 9 and 29, 30 inside and outside the pipe. In other words, it is firmly fixed through any attachment means. In the above-described embodiment, the traveling bodies 9 and 29, 30 inside and outside the pipe are illustrated as traveling in a horizontal state. However, the traveling bodies 9 and 29, 30 perform vertical traveling, oblique traveling, curve traveling, and the like.

上記構成に基き、図1、2を参照して走行装置の一連の動作を説明する。先ず、管内走行体9を左方P方向へ走行移動するには、電磁切換え弁7を開くと共に電磁切換え弁8を閉じてコンプレッサー6から圧縮空気を駆動流体管1内の他側Yに供給する。   Based on the above configuration, a series of operations of the traveling device will be described with reference to FIGS. First, in order to travel and move the in-pipe traveling body 9 in the left P direction, the electromagnetic switching valve 7 is opened and the electromagnetic switching valve 8 is closed to supply compressed air from the compressor 6 to the other side Y in the drive fluid pipe 1. .

これにより受圧面体15で圧縮空気圧を受けた管内走行体9は、両側面に設けた車輪10,11及び上下一対の車輪12が、駆動流体管1の両側内壁面2a,2b及び上下内壁面2c,2dに案内されてP方向へ移動する。この際は、本実施例では一側Xの電磁切換え弁4を閉じると共に電磁切換え弁5を開き空気の排出を可能にする。これらの速度コントロールは、従来周知の方法を任意に採択できる。   As a result, the in-pipe running body 9 that has received the compressed air pressure at the pressure-receiving surface 15 has the wheels 10 and 11 and the pair of upper and lower wheels 12 provided on both sides, and the inner walls 2 a and 2 b and the upper and lower inner walls 2 c of the drive fluid pipe 1. , 2d to move in the P direction. In this case, in this embodiment, the electromagnetic switching valve 4 on the one side X is closed and the electromagnetic switching valve 5 is opened to allow air to be discharged. For these speed controls, conventionally known methods can be arbitrarily adopted.

上記のように管内走行体9が、他側Yから一側Xへ向ってP方向(左側)へ走行すると、管内走行体9の主永久磁石群Aに対して管外走行体29,30の従永久磁石群B1,B2が磁気吸着結合関係の対になっているので、永久磁石1M1及び1M2,1M3は、従永久磁石群B1,B2に対して磁気吸着するので管外走行体29も左右の車輪10,11ないし上下一対の車輪12によって駆動流体管1の両側内壁面2a,2b及び上下内壁面2c,2dに案内支持されてP’方向へ走行する。   As described above, when the in-pipe traveling body 9 travels from the other side Y toward the one side X in the P direction (left side), the in-pipe traveling bodies 29 and 30 are compared with the main permanent magnet group A of the in-pipe traveling body 9. Since the secondary permanent magnet groups B1 and B2 are paired in a magnetic attraction coupling relationship, the permanent magnets 1M1 and 1M2 and 1M3 are magnetically attracted to the secondary permanent magnet groups B1 and B2. The wheels 10 and 11 or a pair of upper and lower wheels 12 are guided and supported by the inner wall surfaces 2a and 2b and the upper and lower inner wall surfaces 2c and 2d of the driving fluid pipe 1 and travel in the P 'direction.

次に、図1に示す管内走行体9を右方Q方向へ走行移動するには、電磁切換え弁4を開くと共に、電磁切換え弁5を閉じてコンプレッサー3から圧縮空気を駆動流体管1内の一側Xに供給する。   Next, in order to travel and move the in-pipe traveling body 9 shown in FIG. 1 in the right Q direction, the electromagnetic switching valve 4 is opened, the electromagnetic switching valve 5 is closed, and compressed air is supplied from the compressor 3 to the driving fluid pipe 1. Supply to side X.

これにより、受圧面体14で圧縮空気圧を受けた管内走行体9は、車輪10〜12が、駆動流体管1の両側内壁面2a,2b及び上下内壁面2c,2dに案内されてQ方向へ移動する。この際は、上記と同様に他側Yの電磁切換え弁7を閉じると共に電磁切換え弁8を開き空気の排出を可能にする。   As a result, the in-pipe traveling body 9 that has received the compressed air pressure at the pressure-receiving surface body 14 moves in the Q direction as the wheels 10 to 12 are guided by the inner wall surfaces 2a and 2b and the upper and lower inner wall surfaces 2c and 2d of the drive fluid pipe 1. To do. At this time, similarly to the above, the electromagnetic switching valve 7 on the other side Y is closed and the electromagnetic switching valve 8 is opened to allow air to be discharged.

上記のように管内走行体9が、一側Xから他側Yへ向ってQ方向(右側)へ走行すると、管内走行体9の主永久磁石群Aに対して管外走行体29,30の従永久磁石群B1,B2が磁気吸着結合関係の対になっているので、永久磁石1M1及び1M2,1M3は、従永久磁石群B1,B2に対して磁気吸着するので管外走行体29も左右の車輪10,11ないし上下一対の車輪12によって駆動流体管1の両側内壁面2a,2b及び上下内壁面2c,2dに案内支持されてQ’方向へ走行する。   As described above, when the in-pipe traveling body 9 travels from the one side X toward the other side Y in the Q direction (right side), the in-pipe traveling bodies 29 and 30 are compared with the main permanent magnet group A of the in-pipe traveling body 9. Since the secondary permanent magnet groups B1 and B2 are paired in a magnetic attraction coupling relationship, the permanent magnets 1M1 and 1M2 and 1M3 are magnetically attracted to the secondary permanent magnet groups B1 and B2. The wheels 10 and 11 or a pair of upper and lower wheels 12 are guided and supported by the inner wall surfaces 2a and 2b and the upper and lower inner wall surfaces 2c and 2d of the driving fluid pipe 1 and travel in the Q 'direction.

以上述べてきたように、本実施例に係る永久磁石を利用した走行装置によれば、駆動流体管1内の左右内壁面に案内支持されて走行する管内走行体9の走行方向前後の車輪10,11と、該管内走行体9に磁気吸着により同期して上記駆動流体管1の両外側面に案内支持されて走行する両管外走行体29,30の車輪16,19の負荷がバランスするので、上記管内走行体9の車輪10,11と両管外走行体29,30の車輪16,19や軌道面の磨耗を軽減することができる。   As described above, according to the traveling device using the permanent magnet according to the present embodiment, the front and rear wheels 10 in the traveling direction of the in-pipe traveling body 9 that travels while being guided and supported by the left and right inner wall surfaces in the drive fluid tube 1. 11 and 11 and the loads on the wheels 16 and 19 of the both-outside pipe running bodies 29 and 30 that run while being guided and supported by both outer side surfaces of the driving fluid pipe 1 in synchronism with the in-pipe running body 9 by magnetic adsorption. Therefore, it is possible to reduce wear of the wheels 10 and 11 of the in-pipe traveling body 9 and the wheels 16 and 19 and the raceway surfaces of both the off-pipe traveling bodies 29 and 30.

これにより、特に、管内走行体9の車輪10,11の寿命を延長することができ、管内走行体9内の主永久磁石群Aと管外走行体29,30内の従永久磁石群B1,B2相互の吸着力を強力にすることが可能となり、管内走行体9に対する管外走行体29,30の追随走行性を向上することができる。   Thereby, in particular, the service life of the wheels 10 and 11 of the in-pipe running body 9 can be extended, and the main permanent magnet group A in the in-pipe running body 9 and the secondary permanent magnet group B1 in the outside-pipe running bodies 29 and 30. It becomes possible to strengthen the mutual adsorption force of B2 and to improve the followability of the outside traveling bodies 29, 30 with respect to the inside traveling body 9.

尚、上述した主永久磁石群Aを構成する各永久磁石1M1,1M2,1M3及び従永久磁石群B1,B2を構成する各永久磁石、ないし反発用永久磁石G1a,G1b及びG2a,G2bは、図示しないヨークによって保持されており、各永久磁石の面はヨークの端部よりやや下がった位置に配設される。   The permanent magnets 1M1, 1M2, 1M3 constituting the main permanent magnet group A and the permanent magnets constituting the secondary permanent magnet groups B1, B2 or the repulsive permanent magnets G1a, G1b and G2a, G2b are shown in the figure. The surface of each permanent magnet is disposed at a position slightly lower than the end of the yoke.

このようにすることで、磁力線がヨークの端部に集中し、磁気吸着力又は反発力が強くなるもので管内走行体の走行に対する管外走行体の追従性が改善する。   By doing so, the lines of magnetic force concentrate on the end of the yoke, and the magnetic attractive force or repulsive force becomes stronger, so that the followability of the outside traveling body to the traveling of the inside traveling body is improved.

次に、永久磁石を利用した走行装置の他の実施例に付き、図3、図4を参照して説明する。図3は、本発明の他の実施例に係る永久磁石を利用した走行装置の走行方向と直交する横断面図、図4は図3のB−B断面図である。なお、上記実施例で述べた構成部分と同一構成部分に付いては同一符号を付してその説明を省略する。   Next, another embodiment of a traveling device using a permanent magnet will be described with reference to FIGS. FIG. 3 is a transverse sectional view orthogonal to the traveling direction of a traveling device using a permanent magnet according to another embodiment of the present invention, and FIG. 4 is a sectional view taken along line BB in FIG. In addition, the same code | symbol is attached | subjected about the component same as the component described in the said Example, and the description is abbreviate | omitted.

本実施例では、管内走行体9内部に収容される主永久磁石群を、幅方向の中央から左主永久磁石群A1’と右主永久磁石群A2’に分割配置したもので、これら両者は磁気的絶縁物で構成された隔壁Hで仕切られている。   In this embodiment, the main permanent magnet group housed in the in-pipe traveling body 9 is divided and arranged from the center in the width direction into the left main permanent magnet group A1 ′ and the right main permanent magnet group A2 ′. It is partitioned by a partition wall H made of a magnetic insulator.

本実施例では、左主永久磁石群A1’と右主永久磁石群A2’は、両外側にN極が、内側にS極が向くように複数の永久磁石1M1’,1M2’,1M3’が左右対称に配列されており、走行方向には隣接する永久磁石1M1’,1M2’,1M3’が交互に異極となるように配設されている。   In the present embodiment, the left main permanent magnet group A1 ′ and the right main permanent magnet group A2 ′ have a plurality of permanent magnets 1M1 ′, 1M2 ′, 1M3 ′ so that the N poles face the outer sides and the S poles face the inner sides. They are arranged symmetrically in the left-right direction, and adjacent permanent magnets 1M1 ′, 1M2 ′, 1M3 ′ are alternately arranged in the traveling direction so as to have different polarities.

一方、駆動流体管1の両外側面には、上記実施例と同様に中心に対し対称構造となる一対の管外走行体29,30が配設されており、管外走行体29,30の内部には、従永久磁石群B1’,B2’の各磁極が上記左主永久磁石群A1’及び右主永久磁石群A2’の両外側に向く磁極と互いに吸着し合う異極関係になるように対応している。   On the other hand, a pair of extra-tube running bodies 29, 30 having a symmetrical structure with respect to the center are disposed on both outer side surfaces of the drive fluid pipe 1, and the extra-tube running bodies 29, 30 are arranged. Inside, the magnetic poles of the secondary permanent magnet groups B1 ′ and B2 ′ are in a different polarity relationship in which they are attracted to the magnetic poles facing the outer sides of the left main permanent magnet group A1 ′ and the right main permanent magnet group A2 ′. It corresponds to.

そして、一対の磁気吸着結合関係にある管内外の走行体9,29,30内の主永久磁石群A1’,A2’と従永久磁石群B1’,B2’の内、何れか一方の主永久磁石群A’,A2’
又は従永久磁石群B1’,B2’の一方側から他方側に沿った端部V,Wに、何れか他方の従永久磁石群B1’,B2’又は主永久磁石群A1’,A2’の走行方向に沿った端部V,Wの永久磁石に対して互いに反発する同極となる反発用永久磁石G1a,G1b及びG2a,G2bが設けられている。
The main permanent magnet groups A1 ′, A2 ′ and the secondary permanent magnet groups B1 ′, B2 ′ in the traveling bodies 9, 29, 30 inside and outside the pipe in a pair of magnetic attraction and coupling relationships are either main permanent. Magnet group A ', A2'
Or, from one side of the secondary permanent magnet groups B1 ′, B2 ′ to the end portions V, W along the other side, either the other secondary permanent magnet group B1 ′, B2 ′ or the primary permanent magnet group A1 ′, A2 ′ Repulsive permanent magnets G1a, G1b and G2a, G2b having the same polarity repelling each other with respect to the permanent magnets at the ends V, W along the traveling direction are provided.

これにより、走行方向に沿った端部Vには反発用永久磁石G1a,G1bが設けられていることから、管内走行体9の移動によって主永久磁石群A1’,A2’の永久磁石1M1’の左方向Pへの移動により、上記永久磁石1M1’の磁極N又はS極に対し反発用永久磁石G1a,G1bの磁極が同極となるよう配設されることで、互いに反発して管外走行体29,30を左方向Pへ押すことになり、慣性があっても、管外走行体29,30のP方向への同期移動がより確実になる。   Thereby, since the repulsion permanent magnets G1a and G1b are provided at the end V along the traveling direction, the permanent magnets 1M1 ′ of the main permanent magnet groups A1 ′ and A2 ′ are moved by the movement of the in-pipe traveling body 9. By moving in the left direction P, the repulsion permanent magnets G1a and G1b are arranged so that the magnetic poles N1 and G1b of the permanent magnet 1M1 ′ have the same polarity as the magnetic poles N and S. The bodies 29 and 30 will be pushed in the left direction P, and even if there is inertia, the out-of-tube traveling bodies 29 and 30 are more surely synchronized in the P direction.

また、走行方向に沿った端部Wには、反発用磁石G2a,G2bが設けられていることから、管内走行体9の移動により主永久磁石群A1’,A2’の永久磁石1M3’が右方向Qへ移動することにより、上記永久磁石1M3’の磁極N又はS極に対し反発用磁石G2a,G2bの磁極が同極となるよう配設されることで、互いに反発して管外走行体29,30を右方向Qへ押すことになり、慣性があっても、管外走行体29,30のQ方向への同期移動がより確実になる。   Further, since the repulsion magnets G2a and G2b are provided at the end W along the traveling direction, the permanent magnets 1M3 ′ of the main permanent magnet groups A1 ′ and A2 ′ are moved to the right by the movement of the in-pipe traveling body 9. By moving in the direction Q, the repulsion magnets G2a and G2b are arranged so that the magnetic poles N2 and G2b have the same polarity with respect to the magnetic pole N or S of the permanent magnet 1M3 ′. 29, 30 is pushed in the right direction Q, and even if there is inertia, the synchronous movement in the Q direction of the extra-tube traveling bodies 29, 30 becomes more reliable.

このようにすることで、重複する記載は省略するが上記実施例と同様な作用効果を得ることができる。なお、本実施例で述べた主永久磁石群A1’,A2’を構成する永久磁石1M1’,1M2’,1M3’は、隔壁Hに対し両外側にS極が、内側にN極が向くように左右対称に配列することもでき、または各磁極を非対称に配列することができる。この場合も、左主永久磁石群A1’と右主永久磁石群A2’の両外側に向く磁極に対向する管外走行体29,30の各磁極は、互いに吸着し合う異極関係になるよう配設されれば良い。また、上記実施例では、主永久磁石群および従永久磁石群は、複数の永久磁石を並設した構成として説明してきたが、これらは互いに磁気吸着結合する主、従関係が得られる単一の永久磁石どうしで構成できることは勿論である。   By doing in this way, although the overlapping description is abbreviate | omitted, the effect similar to the said Example can be obtained. The permanent magnets 1M1 ′, 1M2 ′, 1M3 ′ constituting the main permanent magnet groups A1 ′, A2 ′ described in the present embodiment are oriented so that the south pole faces the outer side and the north pole faces the inner side with respect to the partition wall H. The magnetic poles can be arranged symmetrically with each other, or the magnetic poles can be arranged asymmetrically. Also in this case, the magnetic poles of the out-of-tube traveling bodies 29 and 30 facing the magnetic poles facing the outer sides of the left main permanent magnet group A1 ′ and the right main permanent magnet group A2 ′ have different polar relations that attract each other. What is necessary is just to arrange | position. Further, in the above embodiment, the main permanent magnet group and the secondary permanent magnet group have been described as a configuration in which a plurality of permanent magnets are arranged in parallel. Of course, permanent magnets can be used.
