CORE SAMPLING DEVICE
To provide a wire line type core sampling device that can be shared for soft rock and hard rock, and can simplify its structure and reduce its length.SOLUTION: A wire line type core sampling device comprises an outer tube 12, an inner tube 15 that is inserted to the inside of the outer tube 12 and has a core taking-in part 17 at its tip, and a swivel mechanism 13 that rotatably supports the inner tube 15 relative to the outer tube 12. A support shaft 21 of the swivel mechanism 13 has a first shaft body 24, a second shaft body 25, and a spring member 27. The spring member 27 acts as a compression spring when the inner tube 15 retracts relative to the outer tube 12 in a retraction direction, and acts as a tension spring when the inner tube 15 advances relative to the outer tube 12 in a protrusion direction.SELECTED DRAWING: Figure 2
【課題】軟岩用と硬岩用とに共用可能であるとともに構造を簡単化しかつ短尺化を図ることができるワイヤーライン方式のコア採取装置を提供する。【解決手段】外管１２と、外管１２の内部に挿通されて先端にコア取込部１７を有する内管１５と、外管１２に対して内管１５を回転自在に支持するスイベル機構１３と、を備えるワイヤーライン方式のコア採取装置であって、スイベル機構１３の支持軸２１は、第１軸体２４と、第２軸体２５と、ばね部材２７と、を有し、ばね部材２７は、内管１５が外管１２に対して没入方向に後退する際には圧縮ばねとして機能し、内管１５が外管１２に対して突出方向に前進する際には引っ張りばねとして機能する。【選択図】図２
