Abstract

The present invention relates to a diverter system to allow a line inspection robot to traverse an object. The diverter system includes a first diverter attached to a shield wire, a second diverter attached to the shield wire at a position spaced from the first diverter, and a bridge having a first end connected to the first diverter and a second end connected to the second diverter. The first diverter disengages the robot from the shield wire and onto the bridge and the second diverter disengages the robot from the bridge and onto the shield wire to allow the robot to traverse the object.

Claims

1. A diverter system to allow a line inspection robot to traverse an object, comprising:

(a) a first diverter attached to a shield wire;

(b) a second diverter attached to the shield wire at a position spaced from the first diverter;

(c) a bridge having a first end connected to the first diverter and a second end connected to the second diverter;

(d) wherein the first and second diverters each include a pre-determined transition radius to allow the bridge to ride below the shield wire, and wherein the first diverter disengages the robot from the shield wire and onto the bridge and the second diverter disengages the robot from the bridge and onto the shield wire to allow the robot to traverse the object.

2. The diverter system according to claim 1, wherein the first diverter includes:

(a) a first transfer section adapted to transfer the robot from the shield wire onto the first diverter;

(b) a crossover section adapted to divert wheels of the robot onto the diverting system; and

(c) a second transfer section adapted to transfer the robot from the first diverter onto the bridge.

3. The diverter system according to claim 1, wherein the second diverter includes:

(a) a first transfer section adapted to transfer the robot from the second diverter to the shield wire;

(b) a crossover section adapted to divert wheels of the robot onto the shield wire; and

(c) a second transfer section adapted to transfer the robot from the bridge onto the second diverter.

4. The diverter system according to claim 1, wherein the bridge is flexible.

5. The diverter system according to claim 1, wherein the bridge is rigid.

6. The diverter system according to claim 2, wherein the first transfer section is adapted to move the wheels of the robot from a closed position around the shield wire to an open position sized to mate with the crossover section.

7. The diverter system according to claim 2, wherein the second transfer section is adapted to allow the wheels of the robot to move from an open position sized to mate with the crossover section to a closed position sized to secure the robot to the bridge.

8. The diverter system according to claim 3, wherein the second transfer section is adapted to move the wheels of the robot from a closed position around the bridge to an open position sized to mate with the crossover section.

9. The diverter system according to claim 3, wherein the first transfer section is adapted to allow the wheels of the robot to move from an open position sized to mate with the crossover section to a closed position sized to secure the robot to the shield wire.

10. The diverter system according to claim 1, further including a third diverter adapted to support the bridge at a position between the first and second diverters.

11. The diverter system according to claim 1, the first and second diverters each include opposing sides shaped to mate with grooves of wheels of the robot such that the wheels retain a tight, anti-slip connection with the first and second diverters.
