Boom mountable robotic arm
A boom mountable robotic arm for temporarily supporting an elongate conductor includes a rigid member such as a beam or beam assembly adapted for mounting onto the upper end of a boom for example using a boom adaptor, at least one electrically insulated support post mounted to the rigid member, where each post temporarily supports an elongate electrical conductor, and at least two rotation devices for selectively controllable rotation of the rigid member and the electrically insulated support posts about at least two corresponding axes of rotation.
1. A boom mountable robotic arm for temporarily supporting energized electrical conductors comprising:
a single elongate unitary beam adapted for coupling with an upper end of a boom,
at least two electrically insulated support posts coupled to and spaced apart along said beam, each of said at least two electrically insulated support posts adapted to temporarily support energized electrical conductors,
a first rotation coupling that provides selectively controllable rotation of said beam about a first axis of rotation and wherein said first axis of rotation extends between said beam and the upper end of the boom for rotation of said beam relative to said boom in a substantially vertical plane,
wherein said at least two electrically insulated support posts include first and second insulated support posts coupled one on each of opposite ends of said beam on respective second and third rotation couplings having corresponding substantially parallel axes of rotation allowing distal ends of the first and second support posts, distal from said beam, to rotate towards or away from each other.
2. The boom mountable robotic arm of claim 1 further comprising a boom adaptor mountable to said upper end of the boom;
and wherein said beam is an upper beam assembly rotatably mounted to said boom adaptor for rotation of said upper beam assembly about said first axis of rotation relative to said boom adaptor, said upper beam assembly supporting thereon said at least two electrically insulated support posts and wherein a conductor retainer is mounted on said distal end thereof;
and wherein said first rotation coupling includes a selectively actuable leveling adjustor mounted so as to cooperate between said upper beam assembly and said boom adaptor for selectively adjusting an angular position of said upper beam assembly relative to said boom adaptor.
3. The boom mountable robotic arm of claim 2 wherein said second and third rotation couplings each include a respective actuator cooperating between said upper beam assembly and said at least two electrically insulated support posts for selective inclination of said at least two electrically insulated support posts relative to said upper beam assembly.
4. The boom mountable robotic arm of claim 3 wherein each said electrically insulated support post includes an insulated upright portion and a riser portion, said riser portion having a first end pivotably connected to said upper beam assembly and a second end supporting said insulated upright portion, and wherein each said respective actuator angularly extends from said second end of said riser portion to said upper beam assembly.
5. The boom mountable robotic arm of claim 3 wherein each said respective actuator includes an insulated portion and a lengthwise extendable portion, each said respective actuator angularly extending between a distal end of said insulated support post and said upper beam assembly.
6. The boom mountable robotic arm of claim 2 further including an interruptible conductor having first and second ends and a plurality of the electrically insulated support posts supporting said interruptible conductor away from said upper beam assembly.
7. The boom mountable robotic arm of claim 6 wherein said selectively interruptible conductor comprises a stationary conductor between said distal ends of first and second posts of said at least two electrically insulated support posts and a rotatable conductor extending from said distal end of said second post and being selectively connectable to a distal end of a third post of said at least two electrically insulated support posts.
