Title:
ATTACHMENT MOUNTING/REMOVAL MECHANISM, AND WORK MACHINE
Document Type and Number:
WIPO Patent Application WO/2019/151012
Kind Code:
A1
Abstract:
An attachment mounting/removal mechanism 140, wherein: two pairs of support holes 152, 154 are provided to a work attachment 150, the two pairs of support holes 152, 154 being separated from each other in the swinging direction of the work attachment 150, and forming pairs in an axial direction O that is orthogonal to the swinging direction; pin extension/contraction mechanisms 140A, 140B are built into tip end parts 132A, 136B (connecting portions of arm body 127) disposed between the two pairs of support holes 152, 154, the pin extension/contraction mechanisms 140A, 140B comprising two pairs of pins 142A, 142B that separate from and approach each other in the axial direction O, and linear-motion mechanisms 144A, 144B that support the two pairs of pins 142A, 142B; and the pins 142A, 142B are inserted, respectively, into the support holes 152, 154 when the pin extension/contraction mechanisms 140A, 140B have caused the two pairs of pins 142A, 142B to be driven apart from each other. This makes it possible to ensure stable and reliable workability while allowing the mounting/removal of the work attachment.
