Abstract

The invention is directed to a manipulating device for remotely-controlledanipulation of tools such as an impact wrench or the like. The device includes a support structure for the tool and suspension means for engaging a load hook of a crane pulley or a power manipulator. The support structure includes two side pieces arranged parallel with one another and fixed laterally to the tool. The side pieces contain longitudinally extending slots which connect the end locations which correspond to the horizontal and vertical working positions of the composite assembly made up of the tool and support. The suspension means includes a carrying yoke which can be displaced relative to the support structure. The yoke is guided at its lower end in the longitudinally extending slots. The manipulating device can be moved between its horizontal and vertical working positions without the need for any additional mechanical holding or moving components.

Claims

1. A device for performing remotely-controlled work with a power tool such as an impact wrench or the like, the device being supported from support means such as the loading hook of a crane pulley or a power-driven manipulator or the like, the device comprising:

a frame structure including two side plates fixedly mounted to the power tool, said frame structure and said power tool conjointly defining a composite assembly having a common center of gravity;

guide means formed in each of said plates and connecting a first end location to a second end location, said first end location lying in a first reference plane passing through said common center of gravity and said second end location lying in a second reference plane also passing through said common center of gravity and being perpendicular to said first reference plane; and

,

a yoke suspended from said support means and slidably and pivotally engaging said guide means so as to permit movement of said yoke between said first end location whereat said composite assembly is suspensively held in midair only at said first end location so as to cause the tool to be in a horizontal operating position and said second end location whereat said composite assembly is suspensively held in midair only at said second end location so as to cause the tool to be in a vertical operating position.

2. The device of claim 1, each of said guide means being an elongated slot formed in the side plate corresponding thereto, said elongated slots being mutually adjacent and said plates being mutually parallel;

said yoke having a guide pin mounted thereon, said guide pin having two ends adapted to slidably engage respective ones of said slots.

3. The device of claim 2, each of said elongated slots having two linear segments joined at a predetermined point whereat they define the apex of an obtuse angle so that said segments have respective slopes that are unequal whereby the movement of said yoke between said end locations is facilitated.

4. The device of claim 1, said yoke having guide means formed thereon;

and, each of said side plates having a substantially vertical extension formed thereon above said first end location thereof, said extensions having receiving means formed therein for receiving said guide means when the tool is in said horizontal operating position whereby said composite assembly is stabilized to minimize dangling movements thereof.

5. A device for performing remotely-controlled work with a tool such as an impact wrench or the like, the device being supported from support means such as the loading hook of a crane pulley or a power-driven manipulator or the like, the device comprising;

frame means for fixedly carrying the tool, said frame means and said tool conjointly defining a composite assembly having a common center of gravity; and

,

suspension means for suspending said composite assembly from the support means, said suspension means including;

elongated guide means formed in said frame means and connecting a first end location to a second end location, said first end location lying on a first reference line passing through said center of gravity and said second end location lying on a second reference line also passing through said center of gravity and being transverse to said first reference line; and

,

carrying means connected to said support means and slideably and pivotably engaging said guide means so as to permit movement of said carrying means between said first end location whereat said carrying means suspensively holds said composite assembly in midair so as to cause the tool to be in a first predetermined operating position relative to said reference lines and said second end location whereat said carrying means suspensively holds said composite assembly in midair so as to cause the tool to be in a second predetermined operating position relative to said reference lines.
