Abstract
A gate assembly that can include a frame with first and second mounts to mount the gate assembly across a V-door space on a rig floor, a first gate rotationally attached to a left side of the frame, and a second gate rotationally attached to a right side of the frame, such that the first and second gates selectively permit and prevent access through the V-door space. Inner panels of the first and second gates can be configured to automatically open and close in response to a catwalk extending into the V-door space or retracting from the V-door space.
Claims20
A gate assembly comprising:
- a frame with first and second mounts configured to mount the gate assembly across a V-door space on a rig floor;
- a first gate rotationally attached to a left side of the frame, the first gate comprising a first inner panel rotationally attached to a first outer panel;
- and
- a second gate rotationally attached to a right side of the frame, the second gate comprising a second inner panel rotationally attached to a second outer panel, wherein the first and second gates selectively permit and prevent access through the V-door space, wherein the first inner panel rotates independently of the first outer panel when the first outer panel is engaged with the frame, and wherein the second inner panel rotates independently of the second outer panel when the second outer panel is engaged with the frame.
