Manipulator, system and process of operating the same

Abstract

A joint secured to a manipulator for movably supporting a tool(s) for conducting operations, particularly those in the field is hydraulic to be robust in varied environmental conditions and/or provide sufficient power. The joint includes a base to secure the joint to the manipulator, an adapter to secure a tool to the joint, components movably joined together in close proximity with each other between the base and the adapter to define three non-parallel axes of movement for the adapter wherein two of the axes always intersect a third of the axes, and hydraulically-driven actuators to selectively move and hold the components about the axes.

Description

FIELD OF THE INVENTION[0001]The present invention pertains to a manipulator and systems for movably supporting a tool(s) for conducting operations and processes for operating the same.BACKGROUND OF THE INVENTION[0002]Workers are at times called upon to work in hazardous environments and / or to undertake difficult and / or time-consuming activities. Various tools have been developed to help make such operations safer, easier and / or quicker.[0003]As one example, in mining operations, ground-engaging wear parts are provided along the digging edge of a bucket of an excavating machine such as a dragline machine, cable shovel, face shovel, hydraulic excavator, bucket wheel excavator, and the like. The wear parts protect the underlying equipment from undue wear and, in some cases, also perform other functions such as breaking up the ground ahead of the digging edge. During use, the wear parts typically encounter heavy loading and highly abrasive conditions. As a result, they must be periodica...

Problems solved by technology

During use, the wear parts typically encounter heavy loading and highly abrasive conditions.

In mining operations, these wear parts tend to be heavy and are not easily lifted, which can make replacement difficult, hazardous and/or time consuming.

Nevertheless, though a crane can enable lifting of the wear part, the worker can still be pinched or otherwise injured by using hand tools on the lock or general part handling during removal or installation.

In such unsecured conditions, the wear part may experience uncontrolled movement, such as falling from the bucket and/or shifting or swinging, and risk injuring the worker.

The equipment often cannot be easily moved to a maintenance facility when wear part replacement is needed.

As a result, wear parts are generally replaced in the field where the environment is uncontrolled.

It may be cold, hot, snowing, sleeting, raining, windy, dusty, etc.

Moreover, the ground may be muddy, un-level, and/or unstable.

All of which can make wear part replacement difficult, hazardous and/or time consuming.
