Abstract

An automated vehicle system for laying pipe includes a vehicle (e.g., a stringing trailer) with a bed for storing a plurality of pipes. Tilted gravity members extend across the bed of the vehicle to feed the pipes toward a chute with conveyor running toward the rear of the vehicle. A gate arm and rocker arm mechanism ensure that pipes are fed one at a time onto the conveyor to lay a series of pipes on the ground. Optionally, a joining trailer can be connected behind the vehicle for joining the pipes together before the pipe is placed on the ground.

Claims

1. An automated system for laying a plurality of pipes comprising:

a vehicle with a bed for storing the plurality of pipes;

a conveyor running toward the rear of the bed of the vehicle;

tilted gravity members defining at least a portion of the bed and extending across the vehicle for feeding pipes toward the conveyor;

an opening defined between each of axially spaced gate arms and the gravity members, the opening sized to allow one pipe at a time to enter the conveyor;

said gate arms being adjustable to vary a size of the opening;

an actuator mechanism which feeds the plurality of pipes from the bed of the vehicle through the opening and onto the conveyor, thereby causing the conveyor to lay the plurality pipes in series behind the vehicle, said actuator mechanism being movable independently of said gate arms.

2. The system of claim 1 wherein the gate arms are adjustably mounted to adjust the opening to accommodate different pipe diameters.

3. The system of claim 1 wherein the actuator mechanism further comprises a rocker arm pivoting to feed one pipe at a time onto the conveyor.

4. The system of claim 3 wherein the rocker arm is W-shaped.

5. The system of claim 1 wherein the tilted gravity members comprise a plurality of tilted bars extending across the bed of the vehicle.

6. The system of claim 1 further comprising a transition cradle behind the conveyor for guiding and supporting the pipes exiting the conveyor.

7. A automated system for laying a plurality of pipes comprising:

a vehicle with a bed for storing the plurality of pipes;

a conveyor running toward the rear of the bed of the vehicle;

tilted gravity members extending across the bed of the vehicle for feeding pipes toward the conveyor;

gate arms extending above the conveyor to define an opening between the gate arms and the gravity members, said gate arms being adjustable to vary a size of the opening; and

,

an actuator mechanism with a rocker arm in the opening feeding the pipes from the bed of the vehicle through the opening and onto the conveyor allowing one of the pipes at a time to enter the conveyor, said rocker arm operating independently of said gate arms, thereby causing the conveyor to lay the plurality of pipes in series behind the vehicle.

8. The system of claim 7 wherein the gate arms are adjustably mounted to adjust the opening to accommodate different pipe diameters.

9. The system of claim 7 wherein the rocker arm is W-shaped.

10. The system of claim 7 wherein the tilted gravity members comprise a plurality of tilted bars extending across the bed of the vehicle.

11. The system of claim 7 further comprising a transition cradle behind the conveyor for guiding and supporting the pipes exiting the conveyor.
