Description
【特許請求の範囲】
【請求項１】 先端部にダイヤモンドコアビットを溶着した筒状シャンクと、前記筒状シャンクの後端部に固定した動力連結部と、から成るノンワーク型特殊シャンクであって、
前記筒状シャンクの胴部の外周面に、前記動力連結部から前記ダイヤモンドコアビットまで軸方向に延びる溝を形成し、
前記溝に収まるように、前記動力連結部から前記ダイヤモンドコアビットに供給する冷却剤の流路となる筒状物を固定したことを特徴とするノンワーク型特殊シャンク。
【請求項２】 前記筒状シャンクの軸心には、前記ダイヤモンドコアビットによりコンクリートを穿孔したときに生ずるコアが進入してくる有底のコア進入穴が形成されており、
前記筒状シャンクの胴部の外周面には、前記コア進入穴に連通すると共に前記コア進入穴に進入してきた前記コアを排出するための割れ目が形成されていることを特徴とする請求項１に記載のノンワーク型特殊シャンク。
[Claims]
1. A non-work type special shank comprising a tubular shank in which a diamond core bit is welded to the tip portion and a power connecting portion fixed to the rear end portion of the tubular shank.
A groove extending axially from the power connecting portion to the diamond core bit is formed on the outer peripheral surface of the body portion of the tubular shank.
A non-work type special shank characterized in that a tubular object serving as a flow path for a coolant supplied from the power connecting portion to the diamond core bit is fixed so as to fit in the groove.
2. A bottomed core entry hole into which a core generated when concrete is drilled by the diamond core bit is formed in the axis of the tubular shank.
Claim 1 is characterized in that a crack is formed on the outer peripheral surface of the body portion of the tubular shank to communicate with the core entry hole and discharge the core that has entered the core entry hole. Non-work type special shank described in.
