Description

本発明は、放送衛星や通信衛星を利用してマイクロ波の送信若しくは受信を行なうアンテナに関し、特に、パラボラ反射鏡に対して１次放射器を所定の位置及び姿勢に支持してなるアンテナ装置の構造及び組立方法に関するものである。   The present invention relates to an antenna that transmits or receives microwaves using a broadcasting satellite or a communication satellite, and more particularly, to an antenna device that supports a primary radiator at a predetermined position and posture with respect to a parabolic reflector. The present invention relates to a structure and an assembling method.

例えば、通信衛星からの電波を受信するための衛星通信用のアンテナ装置は、図１５に示す如く、回転放物面からなる反射面(91)を有するパラボラ反射鏡(９)と、パラボラ反射鏡(９)の反射面(91)の焦点位置Ｆに設置された１次放射器(２)と、１次放射器(２)に集められた電波に偏波を施す変換器や送受信回路等が内蔵された屋外ユニット(３)と、パラボラ反射鏡(９)に対して１次放射器(２)及び屋外ユニット(３)を所定の位置及び姿勢に支持する支持機構(92)とを具え、全体が支柱(４)によって支持されている。
パラボラ反射鏡(９)の反射面(91)で受けた電波を効率的に１次放射器(２)へ導くためには、１次放射器(２)をパラボラ反射鏡(９)の焦点位置に正確に設置すると共に、その姿勢を反射面(91)へ向けて正確に規定する必要がある。 For example, an antenna device for satellite communication for receiving radio waves from a communication satellite includes a parabolic reflector (9) having a reflecting surface (91) made of a rotating paraboloid, and a parabolic reflector as shown in FIG. A primary radiator (2) installed at the focal position F of the reflecting surface (91) of (9), a converter for applying polarization to the radio waves collected by the primary radiator (2), a transmission / reception circuit, etc. A built-in outdoor unit (3) and a support mechanism (92) for supporting the primary radiator (2) and the outdoor unit (3) in a predetermined position and posture with respect to the parabolic reflector (9); The whole is supported by the column (4).
In order to efficiently guide the radio wave received by the reflecting surface (91) of the parabolic reflector (9) to the primary radiator (2), the primary radiator (2) is positioned at the focal point of the parabolic reflector (9). It is necessary to accurately define the posture toward the reflecting surface (91).

ところで、アンテナ径の大きなアンテナ装置においては、１次放射器(２)及び屋外ユニット(３)とパラボラ反射鏡(９)とを分解して、アンテナを設置すべき現場まで運搬し、現場にてこれらを組み立てることが行なわれる。
この場合、設置現場において、１次放射器(２)の位置及び姿勢を正確に調整する必要がある。 By the way, in an antenna apparatus having a large antenna diameter, the primary radiator (2), the outdoor unit (3), and the parabolic reflector (9) are disassembled and transported to the site where the antenna is to be installed. These are assembled.
In this case, it is necessary to accurately adjust the position and orientation of the primary radiator (2) at the installation site.

そこで従来は、支持機構(92)を用いた組立において、１次放射器(２)から、パラボラ反射鏡(９)の長軸径Ｇ−Ｇ′(93)の一端(長軸径端)と、短軸径Ｈ−Ｈ′(94)の両端(短軸径端)までの距離を測定し、これらの測定距離が所定の値となる様に、支持機構(92)の調整可能範囲内で１次放射器(２)の位置を調整していた。   Therefore, conventionally, in the assembly using the support mechanism (92), from the primary radiator (2), one end (long axis diameter end) of the long axis diameter GG ′ (93) of the parabolic reflector (9) Measure the distance to both ends (short axis diameter end) of the short axis diameter H-H '(94), and within the adjustable range of the support mechanism (92) so that these measurement distances become a predetermined value The position of the primary radiator (2) was adjusted.

しかしながら、従来の組立方法では、１次放射器(２)の姿勢を調整することが出来ず、組立精度が低い問題があった。特に、アンテナ径の増大に伴って、アンテナの指向性が非常に鋭くなるため、１次放射器(２)の姿勢に関する組立精度の低下が、大きな損失を招いていた。
本発明の目的は、１次放射器の位置及び姿勢を正確に調整することが出来るアンテナ装置の構造及び組立方法を提供することである。 However, the conventional assembly method cannot adjust the attitude of the primary radiator (2), resulting in a problem of low assembly accuracy. In particular, as the antenna diameter increases, the directivity of the antenna becomes very sharp, and a decrease in assembly accuracy related to the attitude of the primary radiator (2) has caused a large loss.
An object of the present invention is to provide an antenna device structure and an assembling method capable of accurately adjusting the position and posture of a primary radiator.

本発明に係るアンテナ装置は、パラボラ反射鏡(１)と、パラボラ反射鏡(１)の焦点位置Ｆに設置された１次放射器(２)と、パラボラ反射鏡(１)に対して１次放射器(２)を所定の位置及び姿勢に支持するための支持機構(40)とを具えている。
支持機構(40)には、１次放射器(２)の設置位置に、１次放射器(２)の中心軸に沿って光ビームを出射すべき光源の取付け構造が設けられている。 The antenna device according to the present invention includes a parabolic reflector (1), a primary radiator (2) installed at a focal position F of the parabolic reflector (1), and a primary with respect to the parabolic reflector (1). A support mechanism (40) for supporting the radiator (2) in a predetermined position and posture is provided.
The support mechanism (40) is provided with a light source mounting structure for emitting a light beam along the central axis of the primary radiator (2) at the installation position of the primary radiator (2).

上記本発明のアンテナ装置の組立においては、例えば支持機構(40)の締め付けを緩めた状態で、該支持機構(40)の調整可能範囲内で１次放射器(２)の位置及び姿勢を調整することが出来る。
調整に際しては、支持機構(40)の１次放射器(２)の設置位置に光源を取り付け、該光源から１次放射器(２)の中心軸に沿って光ビームを発する。これによって、パラボラ反射鏡(１)の反射面(11)には、光ビームのビームスポットが形成されることになる。そこで、該ビームスポットの位置が、所定の位置及び姿勢に設置された１次放射器(２)の中心軸がパラボラ反射鏡(１)の反射面(11)と交叉する位置Ｔに合致する様、支持機構(40)による１次放射器(２)の支持位置を調整する。 In assembling the antenna device of the present invention, the position and orientation of the primary radiator (2) are adjusted within the adjustable range of the support mechanism (40), for example, with the support mechanism (40) tightened. I can do it.
In the adjustment, a light source is attached to the installation position of the primary radiator (2) of the support mechanism (40), and a light beam is emitted from the light source along the central axis of the primary radiator (2). As a result, a beam spot of the light beam is formed on the reflecting surface (11) of the parabolic reflector (1). Therefore, the position of the beam spot matches the position T where the central axis of the primary radiator (2) installed at a predetermined position and posture intersects the reflecting surface (11) of the parabolic reflector (1). The support position of the primary radiator (2) by the support mechanism (40) is adjusted.

ここで、パラボラ反射鏡(１)の反射面(11)に、前記交叉点位置Ｔに一致させて、光源からの光ビームをパラボラ反射鏡(１)の焦点位置Ｆへ向けて反射するための反射部(18)を形成しておき、前記ビームスポットが反射部(18)に照射される様に、１次放射器(２)に対する支持機構(40)の支持状態(位置及び姿勢)を調整すれば、正確な調整が可能である。
反射部(18)にて反射された光ビームは、光源の前面に照射される。そこで、該反射光ビームの照射位置が光源の前面の中心位置に一致する様、１次放射器(２)に対する支持機構(40)の支持状態(位置及び姿勢)を調整することによって、正確な調整が可能である。 Here, the light beam from the light source is reflected toward the focal position F of the parabolic reflector (1) so as to coincide with the crossing point T on the reflecting surface (11) of the parabolic reflector (1). The reflecting part (18) is formed, and the supporting state (position and posture) of the supporting mechanism (40) with respect to the primary radiator (2) is adjusted so that the beam spot is irradiated to the reflecting part (18). Then, accurate adjustment is possible.
The light beam reflected by the reflecting section (18) is irradiated on the front surface of the light source. Therefore, by adjusting the support state (position and posture) of the support mechanism (40) relative to the primary radiator (2) so that the irradiation position of the reflected light beam coincides with the center position of the front surface of the light source, Adjustment is possible.

具体的構成において、前記光源の取付け構造としては、１次放射器(２)と同一の外形を有して、支持機構(40)の１次放射器設置位置に取り付け可能なダミー(25)を具え、該ダミー(25)には、１次放射器(２)と同一方向へ向けて光源が取り付けられる構造を採用することが出来る。
該取付け構造によれば、ダミー(25)に取り付けられた光源から光ビームを発して、支持機構(40)による１次放射器(２)の位置及び姿勢を調整する過程で、ダミー(25)を反射光ビームの照射位置のターゲットとして用いることが出来る。 In a specific configuration, the light source mounting structure includes a dummy (25) that has the same outer shape as the primary radiator (2) and can be mounted at the primary radiator installation position of the support mechanism (40). In addition, a structure in which a light source is attached in the same direction as the primary radiator (2) can be adopted for the dummy (25).
According to the mounting structure, in the process of adjusting the position and posture of the primary radiator (2) by the support mechanism (40) by emitting a light beam from the light source attached to the dummy (25), the dummy (25) Can be used as a target of the irradiation position of the reflected light beam.

本発明に係るアンテナ装置及びその組立方法によれば、パラボラ反射鏡に対する１次放射器の位置及び姿勢を正確に調整することが出来る。   According to the antenna device and the assembling method thereof according to the present invention, the position and posture of the primary radiator with respect to the parabolic reflector can be accurately adjusted.

尚、上述の各ボルトが貫通すべきボルト孔は、ボルトの外径に対して適度な遊びをもって開設されており、該遊びを利用して後述の如く１次放射器(２)の位置及び姿勢の調整を行なうことが可能である。ここで、各ボルト孔を長孔に開設すれば、調整範囲を拡げることが出来る。   The bolt holes through which the bolts are to be penetrated are opened with appropriate play with respect to the outer diameter of the bolt, and the position and orientation of the primary radiator (2) are utilized as described later by using the play. It is possible to make adjustments. Here, if each bolt hole is opened in a long hole, the adjustment range can be expanded.

パラボラ反射鏡(１)には、図１に示す如く、長軸径Ｇ−Ｇ′を反射面(11)に投影した長軸径線(15)と、短軸径Ｈ−Ｈ′を反射面(11)に投影した短軸径線(16)とが交叉する位置、即ち、１次放射器(２)が正確な位置及び姿勢に設置された場合の中心軸(導波方向)が反射面(11)と交叉する位置Ｔに、光ビームが通過可能な内径(例えば５ｍｍ程度)を有する透孔(12)が開設されると共に、パラボラ反射鏡(１)の背面には、図２に示す如くパラボラ反射鏡(１)の透孔(12)から反射面(11)の焦点位置Ｆへ向けてレーザ光(51)を出射すべきレーザポインター(５)の収容筒部(13)が形成されている。   As shown in FIG. 1, the parabolic reflector (1) has a major axis diameter (15) obtained by projecting the major axis diameter GG ′ on the reflecting surface (11) and a minor axis diameter HH ′ as the reflecting surface.

As described above, the receiving tube portion (13) of the laser pointer (5) from which the laser beam (51) should be emitted from the through hole (12) of the parabolic reflector (1) toward the focal position F of the reflecting surface (11) is formed. ing.

上記アンテナ装置の組立においては、先ず上述の支持機構(40)を用いて、図４に示す如く、パラボラ反射鏡(１)に対して１次放射器(２)及び屋外ユニット(３)を仮止め固定する。
又、図２に示す如くパラボラ反射鏡(１)の収容筒部(13)にレーザポインター(５)を装着し、レーザ光(51)を出射せしめる。
又、図３に示す如く、１次放射器(２)のパラボラ反射鏡との対向面(ホーン開口面)には、金属板等からなる反射板(６)を、１次放射器(２)の中心軸に対して垂直に取り付ける、該反射板(６)の表面には、１次放射器(２)の中心軸が貫通する位置に、マーク(61)が施されている。 In assembling the antenna device, first, using the support mechanism (40), the primary radiator (2) and the outdoor unit (3) are temporarily mounted on the parabolic reflector (1) as shown in FIG. Stop and fix.
Further, as shown in FIG. 2, a laser pointer (5) is attached to the accommodating cylinder (13) of the parabolic reflector (1) to emit laser light (51).
Further, as shown in FIG. 3, a reflecting plate (6) made of a metal plate or the like is provided on the surface (horn opening surface) of the primary radiator (2) facing the parabolic reflector, and the primary radiator (2). A mark (61) is provided on the surface of the reflecting plate (6), which is attached perpendicularly to the central axis, at a position through which the central axis of the primary radiator (2) passes.

図４に示す如くレーザポインター(５)から出射されるレーザ光(51)はパラボラ反射鏡(１)の透孔(12)を通過して、１次放射器(２)のパラボラ反射鏡(１)との対向面、即ち、図３に示す反射板(６)に照射され、ビームスポットを形成する。
ここで、１次放射器(２)の取付け位置にずれがある場合、前記ビームスポットは反射板(６)のマーク(61)からずれて形成されることとなる。そこで、ビームスポットがマーク(61)と重なる様、１次放射器(２)の位置を調整する。 As shown in FIG. 4, the laser beam (51) emitted from the laser pointer (5) passes through the through-hole (12) of the parabolic reflector (1) and passes through the parabolic reflector (1) of the primary radiator (2). ), That is, the reflecting plate (6) shown in FIG. 3, and forms a beam spot.
Here, when the mounting position of the primary radiator (2) is deviated, the beam spot is formed deviated from the mark (61) of the reflector (6). Therefore, the position of the primary radiator (2) is adjusted so that the beam spot overlaps the mark (61).

該位置調整は、図５に示すボルト(７)を緩めて屋外ユニット(３)を矢印Ａ方向に揺動させると共に、該揺動面に沿って矢印Ｂ方向に前後移動させる調整と、図６に示すボルト(71)を緩めて支持台(43)を垂直面上で矢印Ｃ方向に揺動させる調整とによって、行なうことが可能である。
又、上述の調整と共に、或いは上述の調整に代えて、図７に示すボルト(72)を緩めて、支持アーム(42)(42)を互いに直交する矢印Ｃ方向及び矢印Ｄ方向に揺動させて、同様の調整を行なうことも可能である。 The position adjustment is performed by loosening the bolt (7) shown in FIG. 5 and swinging the outdoor unit (3) in the direction of arrow A and moving back and forth in the direction of arrow B along the swing surface. It is possible to perform the adjustment by loosening the bolt (71) and adjusting the support base (43) to swing in the direction of arrow C on the vertical plane.
In addition to or in place of the above adjustment, the bolt (72) shown in FIG. 7 is loosened, and the support arms (42) and (42) are swung in the directions of arrows C and D perpendicular to each other. It is also possible to make the same adjustment.

１次放射器(２)の反射板(６)に入射したレーザ光(51)は反射板(６)にて反射され、図４に示す如く該反射レーザ光(52)は、パラボラ反射鏡(１)の反射面(11)にビームスポット(53)を形成する。
ここで、１次放射器(２)の取付け姿勢にずれがある場合、該スポット(53)はパラボラ反射鏡(１)の透孔(12)からずれた位置に形成されることとなる。そこで、反射レーザ光(52)が透孔(12)に戻る様に、１次放射器(２)の姿勢を調整する。
該姿勢調整も、上述の位置調整と同様、図５に示すボルト(７)と図６に示すボルト(71)を緩めて、１次放射器(２)を互いに直交する２方向に揺動させることによって行なうことが出来る。又、図７に示すボルト(72)を緩めて、１次放射器(２)を互いに直交する２方向に揺動させることによって行なうことも可能である。 The laser beam (51) incident on the reflector (6) of the primary radiator (2) is reflected by the reflector (6), and the reflected laser beam (52) is parabolic reflecting mirror (see FIG. 4). A beam spot (53) is formed on the reflecting surface (11) of 1).
Here, when the mounting posture of the primary radiator (2) is deviated, the spot (53) is formed at a position deviated from the through hole (12) of the parabolic reflector (1). Therefore, the attitude of the primary radiator (2) is adjusted so that the reflected laser beam (52) returns to the through hole (12).
In the posture adjustment, the bolt (7) shown in FIG. 5 and the bolt (71) shown in FIG. 6 are loosened and the primary radiator (2) is swung in two directions orthogonal to each other as in the above-described position adjustment. Can be done. It is also possible to loosen the bolt (72) shown in FIG. 7 and swing the primary radiator (2) in two directions orthogonal to each other.

上述の位置調整と姿勢調整は、必要に応じて繰り返し行ない、調整誤差を徐々に零に収束させる。そして、最後に、支持機構(40)の各ボルト(７)(71)(71)を締め付けて、屋外ユニット(３)を固定する。
この結果、１次放射器(２)は正確な位置及び姿勢に設置されることになる。
尚、レーザポインター(５)及び反射板(６)は、組立調整の後は不要となるので、取り外す。 The above-described position adjustment and posture adjustment are repeated as necessary to gradually converge the adjustment error to zero. Finally, the bolts (7) (71) (71) of the support mechanism (40) are tightened to fix the outdoor unit (3).
As a result, the primary radiator (2) is installed in an accurate position and posture.
The laser pointer (5) and the reflector (6) are removed because they are not required after assembly adjustment.

尚、ダミー(25)のフロントカバー(26)を透明シートによって形成すれば、中央孔(27)の形成は省略することが出来る。 On the other hand, the dummy (25) has the same outer shape as the primary radiator (2) as shown in FIGS. 13 (a), (b) and (c), and has a central hole (27) on the front surface thereof. It has a cover (26), is installed through the vertical wall (49a) of the frame (49), and is attached to the vertical wall (49a) of the frame (49) using a plurality of bolts (29). Fixed.
A laser pointer (5) is attached to the axis of the dummy (25), and laser light (51) is emitted from the laser pointer (5) forward through the central hole (27) of the front cover (26). Is possible.
If the front cover (26) of the dummy (25) is formed of a transparent sheet, the formation of the central hole (27) can be omitted.

パラボラ反射鏡(１)には、図８及び図９に示す如く、第１実施例における透孔(12)と同じ位置Ｔに、レーザポインター(５)からのレーザ光(51)を反射して、反射光(52)をパラボラ反射鏡(１)の焦点位置Ｆに照射するための平面の反射部(18)が形成されている。   As shown in FIGS. 8 and 9, the parabolic reflector (1) reflects the laser beam (51) from the laser pointer (5) at the same position T as the through hole (12) in the first embodiment. A planar reflecting portion (18) for irradiating the reflected light (52) to the focal position F of the parabolic reflector (1) is formed.

上記アンテナ装置の組立においては、先ず、図８に示す様に支持機構(40)の支持台(43)に、フレーム(49)を介してダミー(25)及びレーザポインター(５)を取り付け、レーザポインター(５)からレーザ光(51)を照射する。これによってパラボラ反射鏡(１)の反射面(11)にはビームスポットが形成される。
ここで、支持機構(40)によるダミー(25)の取付け位置及び／又は取付け姿勢にずれがある場合、前記ビームスポットはパラボラ反射鏡(１)の反射部(18)の位置からずれて形成されることとなる。そこで、ビームスポットが反射部(18)に照射される様、支持機構(40)によるダミー(25)の支持位置及び支持姿勢を調整する。 In assembling the antenna device, first, as shown in FIG. 8, the dummy (25) and the laser pointer (5) are attached to the support base (43) of the support mechanism (40) via the frame (49), Laser light (51) is emitted from the pointer (5). As a result, a beam spot is formed on the reflecting surface (11) of the parabolic reflector (1).
Here, when the mounting position and / or mounting posture of the dummy (25) by the support mechanism (40) is deviated, the beam spot is formed deviated from the position of the reflecting portion (18) of the parabolic reflector (1). The Rukoto. Therefore, the support position and the support posture of the dummy (25) by the support mechanism (40) are adjusted so that the beam spot is irradiated to the reflection part (18).

パラボラ反射鏡(１)の反射部(18)に入射したレーザ光(51)は反射部(18)にて反射され、反射光(52)は図８に示す如くダミー(25)の前面に照射され、ビームスポットを形成する。
ここで、支持機構(40)によるダミー(25)の取付け位置及び取付け姿勢にずれがある場合、反射光(52)のビームスポットは、ダミー(25)の中央孔(27)の位置には形成されず、ずれが生じることとなる。そこで、反射レーザ光(52)がダミー(25)の中央孔(27)の位置に照射される様、支持機構(40)によるダミー(25)の支持位置及び支持姿勢を調整する。 The laser beam (51) incident on the reflecting portion (18) of the parabolic reflector (1) is reflected by the reflecting portion (18), and the reflected light (52) is applied to the front surface of the dummy (25) as shown in FIG. To form a beam spot.
Here, when the mounting position and mounting posture of the dummy (25) by the support mechanism (40) are misaligned, the beam spot of the reflected light (52) is formed at the position of the central hole (27) of the dummy (25). It will not be shifted. Therefore, the support position and support posture of the dummy (25) by the support mechanism (40) are adjusted so that the reflected laser beam (52) is irradiated to the position of the central hole (27) of the dummy (25).

尚、上述の位置調整及び姿勢調整は、第１実施例と同様に、支持機構(40)の各ボルトを緩めて、支持機構(40)による支持状態を変化させることによって行なうことが出来る。   The position adjustment and the posture adjustment described above can be performed by loosening each bolt of the support mechanism (40) and changing the support state by the support mechanism (40), as in the first embodiment.

上述の位置調整と姿勢調整は、必要に応じて繰り返し行ない、調整誤差を徐々に零に収束させ、その後、支持機構(40)の各ボルト(７)(71)(71)を締め付ける。これによって、支持機構(40)は、１次放射器(２)を正確な位置及び姿勢に支持することが可能な支持状態に固定されることになる。
次に、支持機構(40)の支持台(43)からダミー(25)及びレーザポインター(５)をフレーム(49)ごと取り外し、図１０に示す如く、支持機構(40)の支持台(43)には、フレーム(48)を介して１次放射器(２)及び屋外ユニット(３)を取り付ける。
この結果、１次放射器(２)は正確な位置及び姿勢に設置されることになる。 The above-described position adjustment and posture adjustment are repeated as necessary, the adjustment error is gradually converged to zero, and then the bolts (7) (71) (71) of the support mechanism (40) are tightened. As a result, the support mechanism (40) is fixed in a support state capable of supporting the primary radiator (2) in an accurate position and posture.
Next, the dummy (25) and the laser pointer (5) are removed together with the frame (49) from the support base (43) of the support mechanism (40), and the support base (43) of the support mechanism (40) is removed as shown in FIG. Is attached with a primary radiator (2) and an outdoor unit (3) through a frame (48).
As a result, the primary radiator (2) is installed in an accurate position and posture.

尚、上述の調整作業において、図１４に示す如くフレーム(49)に、屋外ユニット(３)と同一重量のウエイト(33)を取り付けることによって、屋外ユニット(３)の重量を加味した調整が可能となり、更に高い調整精度が得られる。   In the above-described adjustment operation, the weight (33) having the same weight as the outdoor unit (3) is attached to the frame (49) as shown in FIG. Thus, higher adjustment accuracy can be obtained.

上述の如く、本発明に係るアンテナ装置及びその組立方法によれば、設置現場における組立においても、１次放射器(２)の位置及び姿勢を精度良く調整することが出来、これによってアンテナ効率を最大化することが出来る。   As described above, according to the antenna device and the assembling method thereof according to the present invention, the position and orientation of the primary radiator (2) can be adjusted with high accuracy even in the assembly at the installation site, thereby improving the antenna efficiency. Can be maximized.

本発明の各部構成は上記実施の形態に限らず、特許請求の範囲に記載の技術的範囲内で種々の変形が可能である。例えば、１次放射器(２)の位置及び姿勢の調整は、支持機構(40)の遊びの範囲内で行なう構成に限らず、専用の調整機構を設けて行なうことも可能である。   Each part configuration of the present invention is not limited to the above embodiment, and various modifications can be made within the technical scope described in the claims.
