SUBAXLE ATTACHMENT AND DETACHMENT JIG AND SUBAXLE ATTACHMENT AND DETACHMENT METHOD USING THE SAME

To provide a subaxle attachment and detachment jig capable of attaching or detaching a subaxle to or from an axle body, and a subaxle attachment and detachment method using the same.SOLUTION: An attachment and detachment jig 30 of a subaxle 26 pivotally supported in a manner that an axle body 25 extends in a longitudinal direction, as a mounting part of a crawler device included in a travel body of a construction machine. The attachment and detachment jig 30 includes: a frame 31 on which the subaxle 26 is placed; a caster 32 that enables the frame to move; an adjuster 33 that can adjust inclination of the frame; restriction means 34 that restricts a distal end portion of the subaxle 26 on the frame; and insertion and removal means 35 that can insert and remove a support shaft 27 to and from a shaft hole of a proximal end portion of the subaxle 26.SELECTED DRAWING: Figure 4 【課題】サブアクスルをアクスル本体に対して着脱することが可能なサブアクスル着脱治具及びこれを用いたサブアクスル着脱方法を提供する。【解決手段】建設機械の走行体を構成するクローラ装置の装着部として、アクスル本体２５を長手方向に延長する態様で軸支持されるサブアクスル２６の着脱治具３０において、サブアクスル２６を載置する架台３１と、架台を移動可能とするキャスター３２と、架台の傾斜を調整可能なアジャスター３３と、サブアクスル２６の先端部を架台上で拘束する拘束手段３４と、サブアクスル２６の基端部の軸孔に対して支持軸２７を挿抜可能な挿抜手段３５とを備えている。【選択図】図４
