Claims (4)
- 切断対象のガス導管の上部外周に装着固定される支持体と、
上下に立設されるガイド枠を備え前記支持体上に支持される枠体と、
前記ガス導管の下を通して当該ガス導管の周囲に巻回されるワイヤーソーと、
前記ガイド枠に沿って上昇して前記ワイヤーソーに張力を付与すると共に前記ワイヤーソーを走行駆動させる駆動部と、
前記枠体に設けられ前記ワイヤーソーが前記ガス導管を切断する切断進行箇所に向けて火花発生抑止材を噴射する噴射手段とを備え、
前記噴射手段は前記駆動部の上昇に同期して前記切断進行箇所の移動に追従するように噴射位置を変更することを特徴とするガス導管切断装置。 - 前記噴射手段は、前記ガス導管に対して前記ワイヤーソーの走行方向下流側に配備され、前記ガス導管に対して前記ワイヤーソーの走行方向上流側には当該ワイヤーソーを冷却するワイヤーソー冷却手段が設けられることを特徴とする請求項1記載のガス導管切断装置。
- 前記枠体は、前記ガス導管上を走行する前記ワイヤーソーの側方を覆う保護枠を備えることを特徴とする請求項1記載のガス導管切断装置。
- 前記駆動部の回転トルクを検知する検知手段と該検知手段が回転トルクの低下を検知した場合には前記駆動部の駆動を停止させる制御手段を備えることを特徴とする請求項1記載のガス導管切断装置。
