Abstract

A valve operating device includes first and second pivots, a first arm portion extending therebetween, a second arm portion extending from the second pivot, a valve operating machine on the second arm portion, and an actuator connected between the first pivot and the first arm portion. The first arm portion can rotate around a first vertical axis defined by the first pivot and can pivot around a horizontal axis defined by the first pivot. The second arm portion can rotate around a second vertical axis defined by the second pivot. The actuator causes the first and second arm portions, the second pivot, and the valve operating machine to pivot upward and downward relative to the first pivot around the horizontal axis.

First claim

The invention claimed is:

1. A valve operating device comprising:
a first pivot defining a first vertical axis and a horizontal axis;
a second pivot defining a second vertical axis;
a first arm portion between the first and second pivots, wherein the first arm portion is configured to rotate around the first vertical axis defined by the first pivot and is configured to pivot around the horizontal axis defined by the first pivot, the first arm portion being configured to pivot relative to the second pivot;
a second arm portion extending from the second pivot, wherein the second arm portion is configured to rotate around the second vertical axis defined by the second pivot;
a valve operating machine fixedly attached to an end of the second arm portion, the valve operating machine being operable to turn a key to exercise a valve; and
an actuator connected between the first pivot and the first arm portion and configured to cause the first arm portion, the second pivot, the second arm portion and the valve operating machine to pivot upward and downward relative to the first pivot around the horizontal axis.

2. The valve operating device of claim 1 , wherein the actuator is one of an electric cylinder, a linear actuator, and a hydraulic cylinder.

3. The valve operating device of claim 1 , wherein the actuator is pivotally connected to the first pivot.

4. The valve operating device of claim 1 , further comprising a mounting for retaining the valve operating device to a vehicle.

5. The valve operating device of claim 4 , wherein the first arm portion, the second pivot, the second arm portion and the valve operating machine can be pivoted around the first and second pivots to vertically align the first and second pivots into a storage orientation on the vehicle.

6. The valve operating device of claim 1 , wherein the first arm portion includes an upper arm member and a lower arm member.

7. The valve operating device of claim 6 , wherein each pivot includes a mounting cup rotatably mounted on a pedestal.

8. The valve operating device of claim 7 , wherein each mounting cup has a bracket extending therefrom to which the first arm portion is attached.

9. The valve operating device of claim 6 , further comprising a mounting for retaining the valve operating device to a vehicle.

10. The valve operating device of claim 6 , wherein the second arm portion includes first and second members which telescope relative to each other.

11. The valve operating device of claim 10 , wherein the first and second members of the second arm portion can be selectively locked into position relative to each other.

12. The valve operating device of claim 1 , wherein each pivot includes a mounting cup rotatably mounted on a pedestal.

13. The valve operating device of claim 12 , wherein each mounting cup has a bracket extending therefrom to which the first arm portion is attached.

14. The valve operating device of claim 1 , further comprising a first brake configured to lock the first pivot into a desired orientation, and a second brake configured to lock the second pivot into a desired orientation.

15. The valve operating device of claim 14 , wherein the first and second brakes are hydraulic.

16. The valve operating device of claim 14 , further comprising an electronic controller configured to control operation of the first and second brakes.

17. The valve operating device of claim 1 , further comprising a handle on the valve operating machine.

18. A valve operating device comprising:
a first pivot defining a first vertical axis and a horizontal axis;
a mounting for retaining the first pivot to a vehicle;
a second pivot defining a second vertical axis;
a first arm portion between the first and second pivots, wherein the first arm portion is configured to rotate around the first vertical axis defined by the first pivot and is configured to pivot around the horizontal axis defined by the first pivot, the first arm portion being configured to pivot relative to the second pivot, the first arm portion including an upper arm member and a lower arm member;
a first brake configured to lock the first pivot into a desired orientation;
a second arm portion extending from the second pivot, wherein the second arm portion is configured to rotate around the second vertical axis defined by the second pivot, the second arm portion including first and second members which telescope relative to each other and can be locked into position relative to each other;
a valve operating machine fixedly attached to an end of the second arm portion, the valve operating machine being operable to turn a key to exercise a valve;
a second brake configured to lock the second pivot into a desired orientation;
an actuator pivotally connected between the first pivot and the first arm portion and configured to cause the first arm portion, the second pivot, the second arm portion and the valve operating machine to pivot upward and downward relative to the first pivot around the horizontal axis; and
a handle on the valve operating machine.

19. The valve operating device of claim 18 , wherein the actuator is one of an electric cylinder, a linear actuator, and a hydraulic cylinder.

20. The valve operating device of claim 18 , wherein each pivot includes a mounting cup rotatably mounted on a pedestal, each mounting cup having a bracket extending therefrom to which the first arm portion is attached.
