Abstract

An interface between a hydraulic power system and an hydraulically actuated engagement member includes a first portion that is pivotally coupled to a second portion, and has an inlet capable of being coupled to the power system. The second portion is fixedly attached to an attachment bracket capable of interfacing with an attachment. The first portion has a path to provide oil to the second portion, which in turn provides oil from the first portion to the attachment bracket. The attachment bracket includes a housing that accepts an engagement member capable of being hydraulically actuated to secure or release the attachment with respect to the power machine.

Description

technical field [0001] Disclosed embodiments relate to interchangeable tool attachments, such as buckets, grapples, hydraulic hammers, tampers, augers, and such tools that utilize electrically operated arms, such as electric shovels and backhoes. More specifically, embodiments relate to accessories that enable rapid attachment of accessories to electrically operated arms. Background technique [0002] Figure 1A A prior art attachment shown mounted on a bracket 22 is pivotally attached to the end of the shovel arm 18 (partially shown) at the boom pivot joint 20 . An electric shovel arm 18 is connected to an electric shovel or backhoe represented by block 10 . Quick attachment bracket 22 is pivotally connected to hydraulic cylinder 14 via cylinder linkage 26 . A hydraulic cylinder 14 is connected to a portion of the electric shovel or backhoe and to a hydraulic controller 12 represented by block 12 located on the electric shovel or backhoe. The transverse connecting rod 32...
