Benefits of technology

This patent is about an apparatus that attaches a tool to a machine's arm. It includes two coupling means that attach to the machine's arms and the tool, and an actuator that moves the coupling means between a locked position and a retracted position. The apparatus also has a locking sleeve that keeps the coupling means in the locked position. This makes it easier and safer to attach a tool to the machine's arm. The technical benefit of this invention is to improve the efficiency and safety of attaching a tool to a machine's arm.

Problems solved by technology

It is known that the process of removing one work tool from the arm assembly and replacing the work tool with a different work tool may be a time consuming and difficult process.
However, such quick couplers add weight to the stick end and build up the stick height / length.
As a result, the machine's capabilities may be compromised.

Abstract

An apparatus to couple a work tool to an arm assembly is disclosed. The arm assembly may have a first arm and a second arm. The work tool may have a first recess and a second recess. The apparatus may have a first pin that may engage with the first arm and the first recess. The apparatus may have a second pin that may engage with the second arm and the second recess. The apparatus may have an actuator coupled to the first pin and second pin. The actuator may move between a retracted position and an extended position. The apparatus may have a locking sleeve mounted at least partially around the actuator. The locking sleeve may be moveable into a locked position to prevent the actuator from moving into the retracted position from the extended position.

Description

TECHNICAL FIELD[0001]The present disclosure relates to engaging work tools to machines, and more particularly it relates to an apparatus and a method for assembling a work tool to an arm assembly of a machine.BACKGROUND[0002]Machines, such as, hydraulic excavators, hydraulic shovels, backhoe loaders and the like, are often required to perform different kinds of work on a work site. Therefore, different work tools, such as buckets, hammers, rippers, and grapples, may have to be engaged with an arm assembly (including for example, sticks and booms) of the machine. It is known that the process of removing one work tool from the arm assembly and replacing the work tool with a different work tool may be a time consuming and difficult process. Quick couplers have been employed to enable quick engagement of the stick and the work tool and the quick couplers do, to an extent, reduce effort required for removing the work tool and replacing it. However, such quick couplers add weight to the s...
