DETAILED DESCRIPTION OF THE EMBODIMENTS

Before explaining the present apparatus in detail, it is to be understood that the apparatus is not limited to the particular embodiments and that it can be practiced or carried out in various ways.

The present embodiments relate to a vertical pipe handler with pivoting arms and smart grip for a drilling rig.

The present embodiments relate to a type of grip, herein referred to as “smart grip” for use with the pivoting arms of the vertical pipe handler.

A benefit of the vertical pipe handler is the device is capable of handling tubulars in wide ranges of diameter, from 2.27 inches to 20 inches.

Another benefit of this vertical pipe handler is the device facilitates drilling while making up joints simultaneously for offline stand building.

Yet another benefit of this vertical pipe handler is that allows for hands free operation, either mechanized, remotely, or fully automated.

Still another benefit is that the vertical pipe handler has a redundant motor arrangement to maintain operations even during motor failure.

The device has operational sequence and timing that eliminates the pipe handling equipment from critical path of drilling or tripping operations.

The vertical pipe handler has maximal power efficiency by sharing power units with other non-simultaneous rig operations.

Another benefit of the vertical pipe handler is that the installation is efficient and can be transported on top of a portable moveable horizontal to vertical pipe handler, thereby allowing transport of two units with only one trailer.

In an embodiment, the vertical pipe handler can include a central support with a central support center line, which can be mounted parallel to a drilling mast.

The vertical pipe handler can include a non-rotating top base collar, which can slidably move longitudinally on the central support and can be installed around the central support.

The vertical pipe handler can include a rotating top collar, which can be disposed over the non-rotating top base collar. The rotating top collar can provide a wide area of rotation, such as a rotating top collar that provides up to three hundred sixty degrees of rotation.

The vertical pipe handler can include a top pivoting arm, which can be connected to a rotating top collar pad eye of the rotating top collar. The top pivoting arm can be connected to a first pair of hydraulic cylinders. The first pair of hydraulic cylinders can each be double acting, single acting, or other commercially available cylinders.

The vertical pipe handler can include a top pipe grabber, which can be mounted to the top pivoting arm and can be used for grabbing and releasing tubulars. The top pipe grabber can be operated hydraulically.

The vertical pipe handler can include a top rack and top pinion lifting mechanism, which can be mounted to the non-rotating top base collar. The top rack can be fixed to the central support and the top pinion can be connected with the non-rotating top base collar.

The vertical pipe handler can include a top motor and drive gear, which can be used for a slew gear mechanism mounted to the non-rotating top base collar for rotating the rotating top collar.

The vertical pipe handler can include a bottom non-rotating collar, which can be mounted around the central support.

The vertical pipe handler can include a rotating bottom collar, which can include a bottom rotating collar pad eye. The bottom rotating collar pad eye can be mounted over the bottom non-rotating collar.

A bottom pivoting arm can be mounted to the bottom rotating collar pad eye.

The bottom pivoting arm can be connected to a second pair of hydraulic cylinders, which can apply force to the bottom pivoting arm. The second pair of hydraulic cylinders can each be double acting, single acting, or other commercially available cylinders.

The vertical pipe handler can include a bottom pipe grabber, which can open and close to hold the tubulars, such as to hold a tubular parallel to a longitudinal central support centerline of the central support. The bottom pipe grabber can be operated hydraulically.

The vertical pipe handler can include a bottom rack and bottom pinion lifting mechanism, with the bottom rack fixed to the central support and the bottom pinion connected with the bottom non-rotating collar.

The vertical pipe handler can include a bottom motor and a drive gear for a bottom slew gear mechanism, which can be mounted to the bottom non-rotating collar for rotating the rotating bottom collar.

The vertical pipe handler can grab tubulars with the top pipe grabber and the bottom pipe grabber.

The vertical pipe handler can lift the tubulars using the top non-rotating collar and top rack and top pinion lifting mechanisms. The vertical pipe handler can simultaneously rotate the rotating bottom collar and rotating top collar with slew gear mechanisms, which can present tubulars at a well center above a drill floor of a drilling rig.

The vertical pipe handler with pivoting arms can further include bottom pipe grabber pivot pins, bottom collar pivot pins, top pipe grabber pivot pins, and top collar pivot pins.

The central support can connect with the base, and the base can connect to a drill rig substructure.

The base can include one or more gussets for supporting the central support.

In one or more embodiments, the central support can be mounted through a drill floor, on the drill floor, or on a raised horizontal structure of the drill rig.

The vertical pipe handler can also include a racking board, which can be mounted to the central support, such as a racking board mounted opposite the base.

Turning now to the Figures, FIGS. 1A and 1B show the rig system with the vertical pipe handler in two different positions.

FIG. 1A depicts a drilling rig in a deployed position with the vertical pipe handler in a first position grabbing a tubular from the portable moveable horizontal to vertical pipe handler.

The subbase can have two legs 20, 21, which can be pivotably connected to a middle segment 275 fixed to a subbase trailer frame 251 of the subbase trailer 250, thereby allowing the mast 203 to be lowered from a vertical position to lie horizontally on the subbase trailer frame 251 for easy redeployment using a remote control button on the hydraulic control means.

The subbase can also support a drilling platform 273. The subbase can attach to a middle segment 275.

In embodiments, the vertical pipe handler 504 can be coupled to the middle segment 275 of the subbase 262 to prevent the machines from disengaging during operation.

The portable moveable horizontal to vertical pipe handler 502 can be removably coupled to the vertical pipe handler in embodiments.

The subbase trailer frame 251 can also non-removably support a winch 256.

The winch 256 can be used to wind and unwind a hoist line 257, which can be a wire, a cable, or other type of hoisting line, for supporting loads over 50 tons.

The hoisting line 257 is used to raise the mast 203 from a horizontal position for transporting the mast, to a vertical position used for operation of the rig or to lower the mast back to the subbase trailer frame for transport.

The subbase trailer frame of the drilling rig can support a drawworks 210.

A drill line 216 can run from the drawworks 210 to the top of the mast 203 through a crown block 212 at the top of the mast 203 to a traveling block 218 that can connect to a top drive 220.

The traveling block 218, like the top drive 220, can be configured to traverse one of the outer sides of the mast 203 as the top drive with traveling block is used to make up and break down drill pipe and other tubulars and to run the formed drill string into the wellbore.
