Description

【考案の詳細な説明】本考案は高所作業車のブームの先端に取付けら
れ、作業員の搭乗する作業台装置に関するもので
あり、特に電気工事において使用されるものに適
用される。[Detailed Description of the Invention] The present invention relates to a work platform device that is attached to the tip of the boom of an aerial work vehicle and on which a worker rides, and is particularly applicable to those used in electrical work.

電気工事において高所作業車を使用するのは、
電線に防護管を取り付ける場合、配電工事を行な
う場合、電柱上のトランスを交換する場合、電線
に付着した異物を除去する場合等であり、作業員
は常に感電の危険にさらされて作業を行う。 The use of aerial work vehicles in electrical work is
Workers are constantly exposed to the risk of electric shock when performing work such as installing protective tubes on electric wires, performing power distribution work, replacing transformers on utility poles, and removing foreign objects attached to electric wires. .

そして作業員の感電事故を防止する為に作業台
装置を高絶縁材料で作る事が従来より行われてい
る。しかし、従来の作業台装置にあつては水抜用
の穴があいていなかつたので、その作業台装置の
底部に不純物を含有した雨水等がたまつている
と、高所作業時作業台からは見えにくい作業台の
取付部材や平衡シリンダ等が電線等充電部に接触
した場合、作業者が他の充電部の作業中に作業台
内にたまつた雨水等に接触すると充電部間に電位
差が発生し、作業者が感電する恐れがあつた。 In order to prevent electric shock accidents for workers, workbench devices have traditionally been made of highly insulating materials. However, conventional workbench devices do not have holes for draining water, so if rainwater containing impurities accumulates at the bottom of the workbench device, it will drain away from the workbench when working at heights. If a workbench mounting member or balance cylinder that is difficult to see comes into contact with a live part such as a wire, or if a worker comes into contact with rainwater, etc. that has accumulated inside the workbench while working on another live part, a potential difference will occur between the live parts. There was a risk of electric shock to the workers.

本考案は上記の欠点に鑑みてなされたもので、
作業台内に水抜部として水抜穴と絶縁確保用の樋
部材を取付け、耐電圧により絶縁距離を変化させ
作業者の感電事故を防止するものである。 This invention was made in view of the above drawbacks,
A drainage hole and a gutter member for ensuring insulation are installed in the workbench as a drainage part, and the insulation distance is changed depending on the withstand voltage to prevent electric shock accidents for workers.

以下図面により本考案の実施例について説明す
る。 Embodiments of the present invention will be described below with reference to the drawings.

第１図は従来の作業台装置１を示すもので、ブ

で、ブーム２と作業台装置１の間に軸支５，６さ
れ、ブーム２の起伏に応じて伸縮する。 FIG. 1 shows a conventional workbench device 1, which is pivotally supported 4 at the tip of a boom 2. As shown in FIG. Reference numeral 3 denotes a hydraulic cylinder for always maintaining the workbench device 1 in equilibrium, which is supported by shafts 5 and 6 between the boom 2 and the workbench device 1, and expands and contracts according to the ups and downs of the boom 2.

この作業台装置１はFRPで作られ、底面１′及
びその周辺部は一体化した容器として形成される
ため、内部に水が入るとそのままたまつてしま
い、ついには重量増加により作業台が破損してし
まう。 This workbench device 1 is made of FRP, and the bottom surface 1' and the surrounding area are formed as an integrated container, so if water gets inside, it will accumulate and the workbench will eventually be damaged due to the increased weight. Resulting in.

第２図は本考案の実施例を示し、作業台装置底
部に水抜部を設けたものである。 FIG. 2 shows an embodiment of the present invention, in which a water drain portion is provided at the bottom of the workbench device.

これに使用する材料として必要な性質は、水抜
作業が円滑に行なえること、電気絶縁性に優れて
いることである。 The material used for this purpose must have the following properties: be able to drain water smoothly and have excellent electrical insulation properties.

第３図は作業台装置の底面１′に水抜部として

ることが可能である。 In Figure 3, a drain hole 7 is provided on the bottom surface 1' of the workbench device, and a gutter member 8 for ensuring insulation is attached to the bottom of the hole.The length of the gutter member 8 is changed according to the withstand voltage. Varying the insulation distance, that is, the distance between the drain hole 7 and the edge opening of the gutter member 8, ensures insulation,
It can be integrally molded as FRP to facilitate drainage work.

以上の様に本考案によれば、バケツト底面に水
