この発明は、昇降機能付スイッチギヤに関する。   The present invention relates to a switch gear with a lifting function.

従来、特開平４−２４５９４号公報（特許文献１）に開示されるように、スイッチギヤ専用の付属機器であるリフターが知られている。リフターは、スイッチギヤとは別体で構成されている。リフターは、スイッチギヤの筐体内部に格納された遮断器等の電気機器（高圧機器）を出し入れする作業に使用される。   Conventionally, as disclosed in JP-A-4-24594 (Patent Document 1), a lifter that is an accessory device dedicated to a switchgear is known. The lifter is configured separately from the switch gear. The lifter is used for the operation of taking in and out electrical equipment (high voltage equipment) such as a circuit breaker housed inside the switchgear housing.

例えば電気機器を取り出す作業では、作業員は、まず盤正面までリフターを移動する。次にリフターの昇降台の高さを電気機器の設置台の高さに合わせ、筐体内部から電気機器を引き出してリフターに載せ替える。その後、リフターごと電気機器を搬出する。   For example, in the work of taking out the electrical equipment, the worker first moves the lifter to the front of the panel. Next, the height of the lifter lifting / lowering base is adjusted to the height of the installation base of the electric device, and the electric device is pulled out from the inside of the housing and placed on the lifter. Then, the electrical equipment is taken out together with the lifter.

尚、出願人は、本発明に関連するものとして、上記の文献を含めて、以下に記載する文献を認識している。   The applicant has recognized the following documents including the above-mentioned documents as related to the present invention.

特開平４−２４５９４号公報JP-A-4-24594 特開平５−３１６６１４号公報JP-A-5-316614

上記従来のスイッチギヤは、電気機器の出し入れ時において、別体のリフターを配置し操作するために、盤正面に十分に広い作業スペースを確保する必要があった。   In the conventional switchgear, it is necessary to secure a sufficiently large working space in front of the panel in order to place and operate a separate lifter when an electric device is taken in and out.

本発明は、上述のような課題を解決するためになされたもので、スイッチギヤとは別体のリフターを使用することなく、スイッチギヤ内の電気機器を出し入れできる昇降機能付スイッチギヤを提供することを目的とする。   The present invention has been made to solve the above-described problems, and provides a switchgear with a lifting function that can take in and out electrical devices in the switchgear without using a lifter separate from the switchgear. For the purpose.

上記の目的を達成するため、本発明に係る昇降機能付スイッチギヤは以下のように構成される。   In order to achieve the above object, a switchgear with a lifting function according to the present invention is configured as follows.

スイッチギヤは、筐体、昇降台兼用扉、扉昇降手段を備える。筐体は、内部に電気機器を格納でき、盤正面に開口部を有する。昇降台兼用扉は、開口部の少なくとも一部を開閉可能な縦開きの扉であって、閉じた状態で筐体内に収納され、開いた状態で昇降台を兼ねる。扉昇降手段は、昇降台兼用扉を開いた状態で昇降させる。   The switch gear includes a housing, a lifting platform / door, and a door lifting / lowering means. The housing can store electrical equipment inside and has an opening on the front of the panel. The lifting / lowering door is a vertically-opening door that can open and close at least a part of the opening, is housed in the housing in a closed state, and also serves as a lifting / lowering base in the opened state. The door lifting / lowering means moves up and down with the lifting platform combined door opened.

本発明の一態様において、扉昇降手段は、ガイドレール、連結部材、ウインチを備える。ガイドレールは、筐体の側壁内面に上下に渡って設けられる。連結部材は、昇降台兼用扉の回動支点であって、昇降台兼用扉をガイドレールに対して回動可能かつガイドレールに沿って上下動可能に連結する。ウインチは、連結部材をガイドレールに沿って昇降させる。   In one aspect of the present invention, the door elevating means includes a guide rail, a connecting member, and a winch. The guide rail is provided vertically on the inner surface of the side wall of the housing. The connecting member is a pivot point of the lifting / lowering door, and connects the lifting / lowering door to the guide rail so as to be rotatable and vertically movable along the guide rail. The winch moves the connecting member up and down along the guide rail.

本発明の一態様において、昇降台兼用扉は、内面に回転自在なターンテーブルを備える。   In one embodiment of the present invention, the lifting platform door includes a turntable that is rotatable on the inner surface.

本発明に係る昇降機能付スイッチギヤによれば、昇降台兼用扉に昇降機能を設けたことにより、別体のリフターを使用することなく、スイッチギヤ内の電気機器を出し入れすることができる。盤正面での作業にリフターの使用を想定する必要がなくなり、盤正面の作業スペースを縮小できるため保守計画が容易となる。また、昇降台兼用扉は閉じた状態で筐体内に収納されるため、従来のように別体のリフターを保管する場所を確保する必要がない。さらに昇降台兼用扉にターンテーブルを設けることで、盤正面の作業スペースを縮小可能である。   According to the switchgear with a lifting function according to the present invention, the lifting device is provided with a lifting function, so that the electrical equipment in the switchgear can be taken in and out without using a separate lifter. It is no longer necessary to assume the use of a lifter for work on the front of the panel, and the work space on the front of the panel can be reduced, making maintenance planning easier. In addition, since the lifting / lowering door is housed in the housing in a closed state, it is not necessary to secure a place for storing a separate lifter as in the prior art. Furthermore, the work space on the front of the panel can be reduced by providing a turntable on the lifting door.
