Description

本発明は、磁気浮上式鉄道に配置される地上コイルに働く荷重を計測する荷重変換装置に関するものである。   The present invention relates to a load conversion device that measures a load acting on a ground coil arranged in a magnetic levitation railway.

従来、このような分野の磁気浮上式鉄道に配置される地上コイルに働く荷重を計測する荷重変換装置としては、以下に示すようなものがあった。   Conventionally, there has been a load conversion device for measuring a load acting on a ground coil arranged in a magnetic levitation railway in such a field as shown below.

図9はかかる磁気浮上式鉄道に配置される地上コイルに働く荷重を計測する荷重変換装置の構成図、図10はその荷重変換器の表側から見た斜視図、図11はその荷重変換器の裏側から見た斜視図である。   FIG. 9 is a configuration diagram of a load conversion device for measuring a load acting on a ground coil arranged in such a magnetic levitation railway, FIG. 10 is a perspective view seen from the front side of the load converter, and FIG. 11 is a diagram of the load converter. It is the perspective view seen from the back side.

これらの図に示すように、101は磁気浮上式鉄道の軌道の側面に配置されるパネル、102はそのパネルに固定される第1のスタットボルト、103はその第1のスタットボルトに固定される荷重変換器(3分力計)、104は荷重変換器103を固定する第1のナット、105は荷重変換器103の位置を固定する位置固定金具、105Aは荷重変換器103の裏側から形成されたボルト穴、106は荷重変換器103に固定される第2のスタットボルト、107は第2のスタットボルト106に固定される地上コイル、108は地上コイルを固定する第2のナット、109は荷重変換器103からの出力信号を導くケーブルである。   As shown in these figures, 101 is a panel disposed on the side of a magnetic levitation railway track, 102 is a first stat bolt fixed to the panel, and 103 is fixed to the first stat bolt. A load transducer (3-component force meter), 104 is a first nut for fixing the load transducer 103, 105 is a position fixing bracket for fixing the position of the load transducer 103, and 105A is formed from the back side of the load transducer 103. 106, a second stat bolt fixed to the load transducer 103, 107 a ground coil fixed to the second stat bolt 106, 108 a second nut for fixing the ground coil, 109 a load A cable for guiding an output signal from the converter 103.

また、同様の力覚センサや荷重センサとしては、下記特許文献1や2が提案されているが、その取り付けは容易なものではなかった。

Moreover, although the following patent documents 1 and 2 are proposed as the same force sensor or load sensor, its attachment was not easy.
JP 2006-317222 A JP 2006-329653 A

しかしながら、上記した従来タイプの荷重変換装置は、荷重変換器103を第1のスタッドボルト102にねじ込むことにより取り付けるねじ込み式であったために荷重変換器103を回転しなければならなかった。また、このように荷重変換器103を回転させる方式では、ネジピッチでの調整しかできなかった。更に、最終トルクで締付けると回転してしまい垂直、Fz方向の位置の設定が大変難しいといった問題がある。   However, since the above-described conventional load converter is a screw-in type that is attached by screwing the load converter 103 into the first stud bolt 102, the load converter 103 has to be rotated. Further, in the method of rotating the load converter 103 in this way, only adjustment with a screw pitch was possible. Furthermore, there is a problem in that it is difficult to set the positions in the vertical and Fz directions because it rotates when tightened with the final torque.

また、荷重変換器103は、位置固定金具105と第1のナット104により、位置を固定するとともに第1のナット104により締付けて固定するようにしており、その位置決め及び取り付けに難があった。   Further, the load converter 103 is fixed in position by the position fixing bracket 105 and the first nut 104 and fastened by the first nut 104, and there is a difficulty in positioning and mounting.

本発明は、上記状況に鑑みて、荷重変換器は通常のボルト固定式であり、荷重変換器を回転しなくてもよく、荷重変換器の取付けが極めて容易であり、荷重変換器の取り付け高さ及び荷重変換器の三方向の取付方向の精度が高い地上コイルに働く荷重を計測する荷重変換装置を提供することを目的とする。   In the present invention, in view of the above situation, the load converter is a normal bolt fixing type, and it is not necessary to rotate the load converter. An object of the present invention is to provide a load conversion device that measures a load acting on a ground coil with high accuracy in the three mounting directions of the height and load converter.

本発明は、上記目的を達成するために、
〔1〕磁気浮上式鉄道に配置される地上コイルに働く荷重を計測する荷重変換装置において、パネルに固定されるためのボルト穴が形成された台座と、この台座に一体化された荷重変換器と、この荷重変換器に一体化されたスタットボルトと、このスタットボルトを貫通して前記荷重変換器の上面に当接され、ナットで地上コイルを取り付けることを特徴とする。
In order to achieve the above object, the present invention provides
[1] In a load conversion device for measuring a load acting on a ground coil arranged in a magnetic levitation railway, a pedestal in which a bolt hole for fixing to a panel is formed, and a load converter integrated with the pedestal And a stat bolt integrated with the load converter, and abuts on the upper surface of the load converter through the stat bolt, and a ground coil is attached with a nut.

〔2〕上記〔1〕記載の地上コイルに働く荷重を計測する荷重変換装置において、前記荷重変換器のx軸方向及びz軸方向の設定を前記ボルト穴に締着するボルトで行うことを特徴とする。   [2] In the load converter for measuring a load acting on the ground coil according to [1] above, the load converter is set in the x-axis direction and the z-axis direction with a bolt that is fastened to the bolt hole. And

〔3〕上記〔1〕記載の地上コイルに働く荷重を計測する荷重変換装置において、前記台座には調整板を敷くようにしたことを特徴とする。   [3] In the load converter for measuring a load acting on the ground coil according to [1], an adjustment plate is laid on the pedestal.

本発明によれば、従来のスタッドボルトねじ込み式に代えて、通常のボルト固定式とすることにより、荷重変換器の取り付けを容易にすることができる。また、台座に調整板により調整することにより、荷重変換器の取り付け高さの調整を容易にすることができる。更に、通常のボルト固定式により、所定の位置で固定可能になり、荷重変換器のz軸方向の設定も簡便に行うことができる。   According to the present invention, instead of the conventional stud bolt screwing type, it is possible to facilitate the mounting of the load converter by using a normal bolt fixing type. Moreover, the adjustment of the mounting height of the load converter can be facilitated by adjusting the pedestal with the adjustment plate. Furthermore, it can be fixed at a predetermined position by a normal bolt fixing type, and the setting of the load converter in the z-axis direction can be easily performed.

本発明の磁気浮上式鉄道に配置される地上コイルに働く荷重を計測する荷重変換装置において、パネルに固定されるためのボルト穴が形成された台座と、この台座に一体化された荷重変換器と、この荷重変換器に一体化されたスタットボルトと、このスタットボルトを貫通して前記荷重変換器の上面に当接され、ナットで地上コイルを取り付ける。   In a load conversion device for measuring a load acting on a ground coil arranged in a magnetically levitated railway according to the present invention, a pedestal in which a bolt hole for fixing to a panel is formed, and a load converter integrated with the pedestal And a stat bolt integrated with the load transducer, and abuts on the upper surface of the load transducer through the stat bolt and attaches a ground coil with a nut.

以下、本発明の実施の形態について詳細に説明する。   Hereinafter, embodiments of the present invention will be described in detail.

図1は本発明の実施例を示す磁気浮上式鉄道に配置される地上コイルに働く荷重を計測する荷重変換装置の構成図である。   FIG. 1 is a configuration diagram of a load conversion device for measuring a load acting on a ground coil arranged in a magnetic levitation railway showing an embodiment of the present invention.

この図において、1は磁気浮上式鉄道の軌道の側面に配置されるパネル、2はパネル1上に固定されるボルト穴3が形成された高さ調整板、4はその調整板2の上に配置される台座、5は台座4に一体化されている荷重変換器(ここでは、3分力計であるが、1分力や2分力計であっても適用できる)、6は荷重変換器5に一体化されているスタットボルト、7はスタットボルト6を貫通して前記荷重変換器5の上面に当接され、ナット8で固定される地上コイルである。   In this figure, 1 is a panel disposed on the side surface of a magnetic levitation railway track, 2 is a height adjustment plate formed with bolt holes 3 fixed on the panel 1, and 4 is on the adjustment plate 2. The pedestal to be arranged, 5 is a load transducer integrated with the pedestal 4 (here, it is a 3-component force meter, but it can also be applied to 1-component force or 2-component force meter), 6 is load conversion A stat bolt 7 integrated with the vessel 5 is a ground coil that penetrates the stat bolt 6 and is brought into contact with the upper surface of the load transducer 5 and fixed by a nut 8.

図2は本発明の実施例を示す台座上にスタットボルト付き荷重変換器を表側から見た斜視図、図3はその側面図、図4はその裏面から見た斜視図である。   FIG. 2 is a perspective view of a load converter with a stat bolt viewed from the front side on a pedestal showing an embodiment of the present invention, FIG. 3 is a side view thereof, and FIG. 4 is a perspective view seen from the back side thereof.

これらの図に示すように、台座4にはボルト穴3が形成されており、荷重変換器は台座4には荷重変換器5が一体化されており、その荷重変換器5にはスタットボルト6が一体化されている。なお、9は荷重変換器5からの出力信号を導くケーブルである。   As shown in these drawings, a bolt hole 3 is formed in the pedestal 4, and the load converter is integrated with a load converter 5 in the pedestal 4, and the load converter 5 has a stat bolt 6. Are integrated. Reference numeral 9 denotes a cable for guiding an output signal from the load converter 5.

図5は本発明の実施例を示す台座上にスタットボルト付き荷重変換器がパネル上に固定された状態を示す図、図6は本発明の実施例を示す4個の台座上にスタットボルト付き荷重変換器がパネル上に固定された状態を示す図である。   FIG. 5 is a view showing a state in which a load transducer with a stat bolt is fixed on a panel on a pedestal showing an embodiment of the present invention, and FIG. 6 is a view showing a stat bolt attached on four pedestals showing an embodiment of the present invention. It is a figure which shows the state by which the load converter was fixed on the panel.

これらの図に示すように、台座4上のスタットボルト6付き荷重変換器5がパネル1上にボルト3Aにより取り付けられるようになっている。   As shown in these drawings, a load transducer 5 with a stat bolt 6 on a pedestal 4 is attached to the panel 1 by bolts 3A.

図7は本発明の実施例を示す台座上にスタットボルト付き荷重変換器に計測のための地上コイルが設けられた状態を示す側面図、図8は本発明の実施例を示す荷重変換器が取り付けられた地上コイルを表側からみた斜視図である。   FIG. 7 is a side view showing a state in which a ground coil for measurement is provided on a load converter with a stat bolt on a pedestal showing an embodiment of the present invention, and FIG. 8 shows a load converter showing an embodiment of the present invention. It is the perspective view which looked at the attached ground coil from the front side.

このように、地上コイル7の4箇所にスタットボルト6が貫通してナット8で締着されるようになっている。   In this way, the stat bolt 6 penetrates through four locations of the ground coil 7 and is fastened with the nut 8.

したがって、地上コイル7に作用する荷重は、荷重変換器で的確に計測することができる。   Therefore, the load acting on the ground coil 7 can be accurately measured by the load converter.

上記したように構成したので、従来タイプの荷重変換装置は、スタッドボルトねじ込み式であったため荷重変換器を回転しなければならなかった。また、位置固定金具やナット締付け工具が必要であり、取り付けに難があった。特に、現地計測のように計測コイルの隣にも地上コイルがある場合には、工具も入らない状態が発生していた。このため、隣の地上コイルを取り外す必要があった。   Since it comprised as mentioned above, since the load converter of the conventional type was a stud bolt screwing type, it had to rotate the load converter. In addition, a position fixing bracket and a nut tightening tool are required, which makes it difficult to install. In particular, when there is a ground coil next to the measuring coil as in the case of on-site measurement, a state where a tool does not enter has occurred. For this reason, it was necessary to remove the adjacent ground coil.

これに対して、本発明の荷重変換構造は、通常ボルト固定式であり、荷重変換器を回転しなくてよく、その取り付けには特殊なボルトやナット及び取付工具も不要である。このため、隣の地上コイルを取り外す必要がなくなった。   On the other hand, the load conversion structure of the present invention is normally a bolt fixing type, and it is not necessary to rotate the load converter, and a special bolt, nut and mounting tool are not required for the mounting. This eliminates the need to remove the adjacent ground coil.

また、従来タイプの荷重変換構造は、スタッドボルトねじ込み式であったためネジピッチでの荷重変換器高さの調整しかできなかった。これに対して、本発明の荷重変換装置は、荷重変換器の高さの調整にあたり、調整板2で細かい微妙な調整も可能である。ただし、荷重変換器の高さの調整の必要がない場合には、調整板2は省略することができる。   Further, since the conventional type load conversion structure is a stud bolt screw-in type, only the height of the load converter can be adjusted by the screw pitch. On the other hand, the load conversion device of the present invention can be finely and finely adjusted with the adjustment plate 2 when adjusting the height of the load converter. However, the adjustment plate 2 can be omitted when there is no need to adjust the height of the load transducer.

更に、従来タイプの荷重変換構造は、スタッドボルトねじ込み式であったため最終トルクで締付けると荷重変換器が回転してしまい垂直、つまりz軸方向の設定が困難であった。これに対して、本発明の荷重変換構造は、通常ボルト固定式であり、所定の位置で固定可能であり、垂直、つまりz軸方向の設定が簡単であり、三方向(x,y,z)の取付方向精度を高めることができる。   Furthermore, since the conventional type load conversion structure is a stud bolt screw type, when it is tightened with the final torque, the load converter rotates and it is difficult to set the vertical direction, that is, the z-axis direction. On the other hand, the load conversion structure of the present invention is normally a bolt fixing type, can be fixed at a predetermined position, is easy to set in the vertical direction, that is, the z-axis direction, and has three directions (x, y, z). ) Mounting direction accuracy can be increased.

なお、本発明は上記実施例に限定されるものではなく、本発明の趣旨に基づき種々の変形が可能であり、これらを本発明の範囲から排除するものではない。   In addition, this invention is not limited to the said Example, Based on the meaning of this invention, a various deformation | transformation is possible and these are not excluded from the scope of the present invention.

本発明の地上コイルに働く荷重を計測する荷重変換装置は、磁気浮上式鉄道の地上コイルに作用する荷重を的確に計測するための荷重変換装置として利用可能である。   The load converter for measuring the load acting on the ground coil of the present invention can be used as a load converter for accurately measuring the load acting on the ground coil of the magnetic levitation railway.
