CONNECTION DEVICE AND CONNECTION METHOD FOR CONNECTING UNIT ATTACHMENTS OF CONSTRUCTION MACHINE
PROBLEM TO BE SOLVED: To provide a connection device and connection method capable of connecting unit attachments, while avoiding significant weight increase of the attachments.SOLUTION: A connection device (10) for connecting a first unit attachment and a second unit attachment, comprises: a connection pin (80) formed into a cylindrical shape having an inner peripheral face for surrounding an inner space (S); and an insertion device (12). The insertion device (12) comprises a rod (30), a cylinder (20), a cylinder holding part (40) for holding the cylinder (20) in a state of extending over a first facing part and a second facing part, and a reaction force generation member (50) for coming into contact with the first unit attachment or second unit attachment from the second side to the first side, in a state of being connected to a tip end part (30a) of the rod, thereby generating reaction force required for the cylinder (20) to insert the connection pin (80) into each insertion hole (116h, 118h) following to shrinkage of the rod (30).SELECTED DRAWING: Figure 4
【課題】アタッチメントの著しい重量化を回避しながら単位アタッチメント同士を連結することが可能な連結装置及び連結方法を提供すること。【解決手段】第１単位アタッチメントと第２単位アタッチメントとを連結する連結装置（１０）であって、内部空間（Ｓ）を取り囲む内周面を有する筒状に形成された連結ピン（８０）と、挿入装置（１２）と、を備え、挿入装置（１２）は、ロッド（３０）と、シリンダ（２０）と、第１対向部及び第２対向部に跨った状態でシリンダ（２０）を保持するシリンダ保持部（４０）と、ロッドの先端部（３０ａ）に接続された状態で第１単位アタッチメント又は第２単位アタッチメントに対して第２側から第１側に向かって当接することにより、ロッド（３０）が縮むのに伴ってシリンダ（２０）が連結ピン（８０）を各貫通孔（１１６ｈ，１１８ｈ）内に挿入するのに必要な反力を生じさせる反力生成用部材（５０）と、を備えること。【選択図】図４
