ATTACHMENT MOUNTING JIG OF CONSTRUCTION MACHINE, AND CONSTRUCTION MACHINE
To make regulation mechanism regulating opening operation, opening angle and the like of a movable jaw portion to a fixed jaw portion unnecessary, and to store a connection pin respectively in pin storage portions of a fixed jaw portion and a movable jaw portion.SOLUTION: An attachment mounting jig includes a movable jaw portion side connection pin guide face 1b39 and an excessive closure preventing portion 1d1. The movable jaw portion side connection pin guide face 1b39 guides a movable jaw portion side connection pin 2b so as to be stored in a movable jaw portion side pin storage portion 1b30. The excessive closure preventing portion 1d1 prevents excessive closure of a movable jaw portion 1b with respect to a fixed jaw portion 1a so that the movable jaw portion side connection pin 2b abuts to the movable jaw portion side connection pin guide face 1b39 even for a movable jaw portion side connection pin 2b with minimum or maximum pin interval among various attachments mounted in the construction machine, after storing a fixed jaw portion side connection pin 2a in a fixed jaw portion side pin storage portion 1a30, and when making the movable jaw portion 1b move near the movable jaw portion side connection pin 2b by operation of an operation arm 3a of the construction machine and the like and making the movable jaw portion side pin storage portion 1b30 store the movable jaw portion side connection pin 2b.SELECTED DRAWING: Figure 5
【課題】固定アゴ部に対する可動アゴ部の開き動作やその開き角度等を規制する規制機構が不要で、固定アゴ部と可動アゴ部のピン収容部それぞれに連結ピンを収容する。【解決手段】可動アゴ部側連結ピン２ｂが可動アゴ側ピン収容部１ｂ３０に収容されるまで案内する可動アゴ部側連結ピン案内面１ｂ３９と、固定アゴ部側ピン収容部１ａ３０に固定アゴ部側連結ピン２ａを収容後、建設機械の作動アーム３ａ等の動作により可動アゴ部１ｂを可動アゴ部側連結ピン２ｂに近付けて可動アゴ側ピン収容部１ｂ３０に可動アゴ部側連結ピン２ｂを収容させる際、この建設機械で取り付ける各種アタッチメントの内、ピン間隔が最小および最大の可動アゴ部側連結ピン２ｂでも、可動アゴ部側連結ピン２ｂが可動アゴ部側連結ピン案内面１ｂ３９に当接するように固定アゴ部１ａに対する可動アゴ部１ｂの閉じ過ぎを防止する閉じ過ぎ防止部１ｄ１とを有する。【選択図】図５
