1 is a perspective view of an electronic apparatus showing Embodiment 1 of the present invention, and FIG. 2 is a side view thereof. In the figure, reference numeral 2 denotes an electronic device, which includes a housing 21, suspension holes 22 a and 22 b, an opening / closing cover 23, a hinge 24, and a balance weight 25. The balance weight 25 may change the type of weight, for example, 5 kg, 10 kg, or may be a combined weight.
On the back side of the housing 21, an upper suspension hole 22a and a lower suspension hole 22b are provided. The opening / closing cover 23 is substantially U-shaped and is connected to the housing 21 by a hinge 24 provided in the vicinity of the lower suspension hole 22b. A balance weight 25 is attached to the opening / closing cover 23 on the side opposite to the hinge by a detachable fixture (not shown). As the detachable fixture, for example, it may be mechanically fastened with screws, or may be magnetically fixed by magnetic force. The attachment / detachment fixture of the opening / closing cover 23 is provided with a center of gravity adjustment unit (not shown) that finely adjusts the position of the center of gravity G by moving the position of the balance weight 25. The center of gravity adjustment unit may be a combination of a long hole provided in the longitudinal direction of the opening / closing cover 23 and a screw fastening, or a combination of a scale provided in the longitudinal direction of the opening / closing cover 23 and magnetic fixing. .
本発明が従来技術と異なる部分は、電子機器の背面側が下側ヒンジ付きの開閉カバーとなっており、その反ヒンジ側にバランスウェイトを取り付けることで電子機器の重心位置を移動させることができる部分である。 The part where the present invention is different from the prior art is that the back side of the electronic device is an open / close cover with a lower hinge, and the center of gravity of the electronic device can be moved by attaching a balance weight to the opposite hinge side It is.
次に、動作について説明する。
（１）電子機器２の重心Ｇは吊穴２２ａ，２２ｂを通る鉛直方向の平面上には位置せず、やや前寄りの位置にある。
（２）開閉カバー２３を開く。
（３）開閉カバー２３の反ヒンジ側の着脱固定具にバランスウェイト２５を取り付ける。
これにより、重心Ｇは後方に移動する（図２の矢印の方向）。
電子機器２の重量、重心位置に応じてバランスウェイト２５の重量、取り付け位置を選択することにより、正立する電子機器２の吊穴２２ａを通る鉛直方向の平面上に電子機器の重心位置２１を一致させることができる。このように、重心Ｇを調整することで、電子機器２を傾けることなく正立させて吊り上げることができる。
Next, the operation will be described.
(1) The center of gravity G of the electronic device 2 is not located on the plane in the vertical direction passing through the suspension holes 22a and 22b, but is located slightly forward.
(2) Open the opening / closing cover 23.
(3) The balance weight 25 is attached to the attachment / detachment fixture on the side opposite to the hinge of the opening / closing cover 23.
As a result, the center of gravity G moves backward (in the direction of the arrow in FIG. 2).
By selecting the weight and mounting position of the balance weight 25 according to the weight and center of gravity of the electronic device 2, the center of gravity position 21 of the electronic device is set on the vertical plane passing through the suspension hole 22a of the electronic device 2 standing upright. Can be matched. Thus, by adjusting the center of gravity G, the electronic device 2 can be lifted upright without being inclined.
バランスウェイトは電子機器の運搬中や設置後には取り外しておくことで、開閉カバー自体が軽量になり開閉操作を小さい力で行えるだけでなく、電子機器の重量を軽減して取り扱うことができる。また、開閉カバーは略Ｕ字形に形成することで、剛性が高められておりバランスウェイトを取り付けた場合の撓みを抑えているので、カバーの変形防止のための補強部品を削減できる。さらに、本実施例の電子機器を用いれば、小型で、コストを低減した制御盤を得ることができる。 By removing the balance weight during transportation or after installation of the electronic device, the opening / closing cover itself becomes lighter and the opening / closing operation can be performed with a small force, and the weight of the electronic device can be reduced. Further, since the opening / closing cover is formed in a substantially U shape, the rigidity is enhanced and the bending when the balance weight is attached is suppressed, so that it is possible to reduce the number of reinforcing parts for preventing deformation of the cover. Furthermore, if the electronic apparatus of the present embodiment is used, a control panel that is small in size and reduced in cost can be obtained.
図３は本発明の実施例２を示す斜視図であり、電子機器２を制御盤１に設置する方法を示している。図において、１は電子機器２を設置する制御盤、３３は電子機器２を吊り上げるロープである。
制御盤１の中に電子機器２を設置するには、次のようにする。
（１）電子機器２の開閉カバー２３を開いてバランスウェイト２５を取り付ける。
（２）吊穴２２ａにロープ３３を接続する。
（３）天井クレーン等（図示せず）でロープ３３を巻き上げ、電子機器２を少し吊り上げる。この際、電子機器２が正立しない場合はバランスウェイト２５の位置を微調整し、重心の位置を変える重心調整部にて調整し、電子機器２を正立させる。
（４）電子機器２を正立させて吊り上げて制御盤１内へ移動し、設置を行う。
このようにすることにより、電子機器２は人手や別の保持装置に頼ることなく、制御盤１内への移動、設置を容易に行うことができる。また、制御盤を新設する場合に限らず、保守や故障による電子機器の交換時にも撤去、設置作業が容易に行えるので、短時間で交換を完了でき、短時間で復旧、運転させることができる。さらに、制御盤内の吊り込みヤードが不要になるので制御盤を小型化できる。
FIG. 3 is a perspective view showing a second embodiment of the present invention, and shows a method of installing the electronic device 2 on the control panel 1. In the figure, 1 is a control panel on which the electronic device 2 is installed, and 33 is a rope for lifting the electronic device 2.
The electronic device 2 is installed in the control panel 1 as follows.
(1) Open the open / close cover 23 of the electronic device 2 and attach the balance weight 25.
(2) The rope 33 is connected to the suspension hole 22a.
(3) The rope 33 is wound up with an overhead crane or the like (not shown), and the electronic device 2 is slightly lifted. At this time, if the electronic device 2 does not stand upright, the position of the balance weight 25 is finely adjusted and adjusted by the center-of-gravity adjustment unit that changes the position of the center of gravity, and the electronic device 2 is put upright.
(4) The electronic device 2 is lifted upright, moved into the control panel 1 and installed.
By doing in this way, the electronic device 2 can be easily moved and installed in the control panel 1 without relying on a manual or another holding device. In addition, not only when installing a new control panel, but also when removing or replacing electronic equipment due to maintenance or failure, it can be easily removed and installed, so replacement can be completed in a short time, and it can be restored and operated in a short time. . Further, since the suspension yard in the control panel is not required, the control panel can be downsized.
