Abstract

Claims (45)

1 . A method for installing a Stockbridge damper onto a longitudinal length of a wire, the method comprising:

a) placing a robotic Stockbridge damper installer on the wire, the robotic Stockbridge damper installer comprising:

i) a frame configured to straddle the wire when placed thereupon, the frame further comprising opposing frame members extending downwardly therefrom,

ii) a pair of motorized wheels configured to traverse along the wire, each of the motorized wheels comprising an electric hub motor disposed therein,

iii) a lifting mechanism operatively coupling the pair of motorized wheels to the frame, the lifting mechanism configured to raise and lower the frame relative to the wire,

iv) at least one swingarm mechanism operatively coupled to the frame, the at least one swingarm mechanism configured to hold the at least one Stockbridge damper and further configured to rotate the at least one Stockbridge damper towards the wire for installation thereupon, and

v) a battery configured to provide direct current (“DC”) power, the battery operatively coupled to the pair of motorized wheels, to the lifting mechanism, and to the at least one swingarm mechanism to provide DC power thereto,

the robotic Stockbridge damper installer further configured to traverse along the longitudinal length of the wire, the robotic Stockbridge damper installer configured to hold at least one Stockbridge damper, the robotic Stockbridge damper installer loaded with the at least one Stockbridge damper;

b) moving the robotic Stockbridge damper installer along the longitudinal length of the wire; and

c) installing the at least one Stockbridge damper on the wire with the robotic Stockbridge damper installer at pre-determined locations on the wire.

2 . The method as set forth in claim 1 , further comprising lifting the robotic Stockbridge damper installer from the wire after the robotic Stockbridge damper installer has installed the at least one Stockbridge damper onto the wire.

3 . The method as set forth in claim 2 , further comprising returning the robotic Stockbridge damper installer to the ground surface.

4 . The method as set forth in claim 3 , further comprising re-loading one or more of the at least one Stockbridge damper onto the robotic Stockbridge damper installer and repeating the steps of claim 1 .

5 . The method as set forth in claim 1 , further comprising placing the robotic Stockbridge damper installer onto the wire with a lifter.

6 . The method as set forth in claim 5 , wherein the lifter comprises one or more of an unmanned aerial vehicle, a crane and a bucket truck.

7 . The method as set forth in claim 1 , wherein the wire comprises an electric power line or a guy wire.

8 . The method as set forth in claim 1 , wherein the lifting mechanism comprises:

a) a first DC electric servo motor operatively coupled to the frame, the first DC electric servo motor comprising a servo arm operatively coupled thereto;

b) a pivot arm operatively coupling one of the pair of motorized wheels to the frame; and

c) a linkage operatively coupling the pivot arm to the servo arm, wherein operation of the first DC electric servo motor causes the servo arm to rotate and move the pivot arm towards or away from the frame to thereby raise or lower the frame.

9 . The method as set forth in claim 8 , wherein the at least one swingarm mechanism comprises:

a) a second DC electric servo motor disposed on the frame;

b) a swingarm pivotally coupled to the second DC electric servo motor;

c) a clamp arm pivotally coupled to the swingarm, the combination of the swingarm and the clamp arm configured to hold one of the at least one Stockbridge damper, the clamp arm further comprising a biasing member configured to pivot the clamp arm towards the swingarm; and

d) a rotary impact driver operatively coupled to the swingarm, the rotary impact driver configured to clamp the at least one Stockbridge damper onto the wire when the at least one swingarm mechanism is rotated to install the at least one Stockbridge damper onto the wire.

10 . The method as set forth in claim 9 , wherein the at least one Stockbridge damper comprises a clamp with a breakaway bolt configured to tighten the clamp onto the wire, and the rotary impact driver comprises a socket configured to rotationally engage a breakaway section disposed on the breakaway bolt, whereupon operation of the rotary impact driver rotates the breakaway bolt to tighten the clamp to the wire until the breakaway section shears off of the breakaway bolt at a predetermined torque.

11 . A system for installing at least one Stockbridge damper onto a longitudinal length of a wire, the system comprising:

a) a frame configured to straddle the wire when placed thereupon, the frame further comprising opposing frame members extending downwardly therefrom;

b) a pair of motorized wheels configured to traverse along the wire, each of the motorized wheels comprising an electric hub motor disposed therein;

c) a lifting mechanism operatively coupling the pair of motorized wheels to the frame, the lifting mechanism configured to raise and lower the frame relative to the wire;

d) at least one swingarm mechanism operatively coupled to the frame, the at least one swingarm mechanism configured to hold the at least one Stockbridge damper and further configured to rotate the at least one Stockbridge damper towards the wire for installation thereupon, the at least one Stockbridge damper comprising a clamp configured to fasten to the wire with a breakaway bolt wherein the breakaway bolt comprises a breakaway section configured to shear off of the breakaway bolt at a predetermined torque; and

e) a battery configured to provide direct current (“DC”) power, the battery operatively coupled to the pair of motorized wheels, to the lifting mechanism, and to the at least one swingarm mechanism to provide DC power thereto.

12 . The system as set forth in claim 11 , wherein the lifting mechanism comprises:

a) a first DC electric servo motor operatively coupled to the frame, the first DC electric servo motor comprising a servo arm operatively coupled thereto;

b) a pivot arm operatively coupling one of the pair of motorized wheels to the frame; and

c) a linkage operatively coupling the pivot arm to the servo arm, wherein operation of the first DC electric servo motor causes the servo arm to rotate and move the pivot arm towards or away from the frame to thereby raise or lower the frame.

13 . The system as set forth in claim 12 , wherein the at least one swingarm mechanism comprises:

a) a second DC electric servo motor disposed on the frame;

b) a swingarm pivotally coupled to the second DC electric servo motor;

c) a clamp arm pivotally coupled to the swingarm, the combination of the swingarm and the clamp arm configured to hold one of the at least one Stockbridge damper, the clamp arm further comprising a biasing member configured to pivot the clamp arm towards the swingarm; and

d) a rotary impact driver operatively coupled to the swingarm, the rotary impact driver configured to clamp the at least one Stockbridge damper onto the wire when the at least one swingarm mechanism is rotated to install the at least one Stockbridge damper onto the wire.

14 . The system as set forth in claim 13 , wherein the rotary impact driver further comprises a socket configured to rotationally engage the breakaway section disposed on the breakaway bolt, whereupon operation of the rotary impact driver rotates the breakaway bolt to tighten the clamp to the wire until the breakaway section shears off of the breakaway bolt at the predetermined torque.

15 . The system as set forth in claim 11 , further comprising a lifter configured to place the robotic Stockbridge damper installer on the wire.

16 . The system as set forth in claim 15 , wherein the lifter comprises one or more of an unmanned aerial vehicle, a crane and a bucket truck.
