Definitions

  • the present invention relates to equipment for pipeline construction and/or maintenance technology.
  • these weld or inspection units include wheel systems designed to facilitate longitudinal travel in the pipe.
  • the wheels of these wheel systems are typically oriented for rollably supporting the unit in a longitudinal direction (i.e., wheels axes perpendicular to a longitudinal pipeline centerline). This wheel orientation is typically perpendicular to the orientation the wheels would need to have in order to facilitate rotational (i.e., about the pipe longitudinal axis) rolling (i.e., from 12: 10 o'clock back to 12:00 o'clock).
  • these longitudinal travel wheel systems in contact with a pipe interior surface) for facilitating longitudinal movement would normally serve to frictionally discourage/inhibit or even prevent rotation of the unit about the longitudinal axis.
  • these welding or inspection units are very heavy so as to create a large amount of frictional force opposing any effort to urge the unit rotationally back into a more desired orientation or positioning. It would therefore be desirable to provide a system that reduced the force and energy necessary to reposition a unit within a pipe to a desirable rotational orientation. Specifically, it would be desirable to reduce the force necessary to rotate a unit so that an operator applying a predetermined amount of torque to the unit could rotationally reorient the unit (e.g., manually) about the longitudinal center line of the pipe.
  • a pipeline unit may include a first longitudinal roller support system that rollingly supports the pipeline unit as it travels longitudinally within the pipe.
  • the pipeline unit may also support a second rotational roller system which transfers at least a portion of the weight of the pipeline unit to the rotational roller or load support mechanism and which facilitates rotational positioning/repositioning within the pipeline.
  • This second rotational roller system may comprise a single unit or multiple similar units position longitudinally for bearing the weight of the pipeline unit.
  • the rotational roller load support mechanism includes a low friction base portion that allows the unit to be supportably rotated on the roller system via the base portion.
  • the base portion may include a friction reduction mechanism such as in-line wheels.
  • the invention includes a roller system for supporting the rotational repositioning of a pipeline unit against the weight of the pipeline unit.
  • the pipeline unit includes a main frame to which its components are secured.
  • the roller system includes at least one wheel including a rotational axis, the axis could be generally parallel to a longitudinal center line of the unit. While a wheel can be used as a friction reducing base, any low friction mechanism may also be utilized. When the low friction base member utilizes a wheel, a wheel frame can be provided for supporting the wheel and allowing the wheel to rotate about an axis.
  • An extension member is also provided with the present invention roller that extends from the pipeline unit toward and in contact with an interior of the pipeline to transfer the load of the pipeline unit to the roller system and then to the pipeline interior.
  • the extension portion includes a first member connected to the main frame and a second member connected to the wheel frame.
  • the second portion is supported by and selectively extends (e.g., telescopically) relative to the first portion to cause at least a portion of the weight of the pipeline unit to be borne by the wheel.

  • nose end 12 of the pipeline unit 10 is visible and extends out of the end of pipeline 200.
  • a lever receptacle 20 is located on a peripheral side of pipeline unit 10 for receiving an end of a lever 30. When lever 30 is received in lever receptacle 20, an operator may apply a positive/negative rotational force F thereto in order to rotate pipeline unit 10 relative to pipeline 200 about a longitudinal central axis of the pipeline and the pipeline unit 10.
  • Figure 2 shows a side view of pipeline unit 10 and forward and rear low or reduced friction bases 68 attached thereto and extending therefrom.

  • a plurality of wheels 60 are set at a general radial periphery of pipeline unit 10. Wheels 60 are for supporting the pipeline unit 10 as it rolls longitudinally within pipeline 200.

  • Members 130 include beam side walls 130A, lateral beam connectors 130B, a reaction force beam 130C, and bottom beam member 130D.
  • Side walls 130A support angle support members 120A and 120B to which upper ends of springs 72A and 72B are connected and through which those springs 72A, 72B transfer their retracting forces to wheel frame 70.

  • An extending member 74 includes a first portion 104 and a second portion 106.
  • First portion 104 is slidably connected to second portion 106. Specifically, at least a portion of second portion 106 can be forced away from or drawn toward first portion 104.
  • first portion 104 is a hydraulic or pneumatic cylinder that slidably or telescopically receives second portion 106 which is a piston.
  • a screw or gear mechanism may be utilized (e.g., with an electric motor).
  • an electronic controller may be used to control the supply of fluid and thus control piston extension and retraction.
  • the cylinder of first portion 104 is connected to main frame 100. For example, a bottom end of first portion 104 can be connected to reaction force beam 130D.
  • first portion 104 could be connected to a portion of main frame 130 so long as that connection allows for transfer of load from the frame to first part 104.
  • second portion 106 is forcibly extendable away from first portion 104 such that extending member 74 can exist in an extended configuration (shown in Figures 3 and 6) and a retracted configuration (shown in Figures 4 and 5).
  • a manual or electronic controller may be used to turn the supply fluid on and off.
  • Figures 3-6 also show biasing members or springs 72A and 72B.
  • Springs 72A and 72B provide a retracting force for urging wheel frame 70 toward the retracted configuration of Figures 4 and 5.
  • Figure 4 shows a pedestal structure 110 for supporting the pipeline unit 10 when the pipeline unit 10 is not inserted in a pipeline 200.
  • Reaction force beam 130D provides the reaction force which transfers the load of pipeline unit 10 to rotational roller system 68. Specifically, since reaction force beam 130D is a part of main frame structure 100, when extending member 74 extends, load/weight is transferred from beam 130D of pipeline unit 10 to first portion or cylinder 104 then to piston or second portion 106 then to wheel frame 70 and then to an interior surface of pipeline 200.
  • extending member 74 When extending member 74 is actuated via a pneumatic mechanism, an operator simply operates a manual valve that supplies working fluid (e.g., air or another gas) to the system.
  • working fluid e.g., air or another gas
  • a valved gas/air supply line may supply gas between air tank 65 and the first cylinder portion 104 of the rotational roller system.
  • An operator controls a valve so that gas introduced into cylinder 104 forces piston 106 radially outward toward a pipe interior surface until wheel frame 70 is in contact with the pipe interior surface.
  • Piston 106 extends after contact with the pipe interior surface bearing the load of pipeline unit 10 until pipeline unit 10 is raised about 1 ⁇ 4 to about 1 ⁇ 2 inches off the pipe interior surface.
  • air pressure from air tank 65 is stopped and the air pressure in the cylinder 104 is allowed to vent to the atmosphere.
  • Biasing members or springs 72 may then return wheel frame 70 to its retracted position.
  • air pressure may also be used to forcibly retract the system.
  • roller system 68 When one roller system is used, longitudinal positioning of the roller system 68 on the pipeline unit 10 can be such that the roller system is at or near the center of gravity of pipeline unit 10. That single roller system 68 would then function as fulcrum so that when pipeline unit 10 is balanced on that fulcrum most, if not all, of the weight of pipeline unit 10 is borne by roller system 68. Positioning of the roller system near or in proximity to wheels 60 can also be beneficial as such positioning has the potential to minimize the load borne by wheels 60. As such, less load on wheels 60 means less friction via wheels 60 on pipeline interior to overcome while rotating pipeline unit 10 about the longitudinal axis. As also shown in Figure 2, multiple roller systems may be utilized to further reduce rotational friction. Figure 2 shows two roller systems 68 positioned to bear some of all of the weight of pipeline unit 10. Here, both roller systems 68 are positioned in proximity to wheels 60.
  • roller systems 68 may be used for load transfer. These roller systems 68 may be positioned at various longitudinal position(s) along the length of the pipeline unit 10. Instead of pistons a screw type or other type of linear actuator may be utilized. Furthermore, power for energizing these various types of linear actuators may include AC or DC (e.g., batteries) electric power and electric motors for generating the necessary lifting forces.
