Definitions

  • This invention relates to an apparatus for storing a coil of pipe and for dispensing the pipe.
  • the apparatus is particularly suitable for use with coils of pipe of the type typically used for transporting mains services underground.
  • the invention also relates to a trailer comprising the apparatus which is suitable for transporting coils of pipe and a method of using the apparatus.
  • Underground pipes are frequently installed to deliver services to residential and commercial properties, for example mains water and gas.
  • Underground pipes can also serve as conduits for electrical cables and communication links.
  • Such pipes are typically manufactured as flexible, thin walled structures formed of plastics materials, for example polyethylene (PE).
  • PE polyethylene
  • a problem associated with the storage and transportation of pipe coils is that the forming of the pipe into a coil induces significant bending stresses in the pipe.
  • the magnitude of the stresses depends on the wall thickness of the pipe and the diameter of the coil.
  • the bending stresses are stored in the coil as potential energy and the pipe is typically prevented from relaxing during transportation by straps which are tightened around the turns of the coil at multiple locations.
  • Another problem relates to the dispensation of pipe from the coi! after it has been transported to the installation site, in general, the pipe is passed directly from the coil into an excavation for installation.
  • the directing of the pipe downwards into an excavation typically involves the further bending of the pipe and, again, significant bending stresses are induced which may create a risk of injury is appropriate safety measures are not taken.
  • an apparatus for storing a coil of pipe and for dispensing the pipe comprising a frame which defines an interior volume for receiving the coil, the frame being provided with a dispensing arm pivotally mounted about a horizontal axis to extend outwardly from the frame, wherein the dispensing arm is provided with a pipe restraining means for restricting movement of the pipe in directions transverse to the pipe while allowing dispensation of the pipe in the longitudinal direction of the pipe.
  • the invention thus provides a pivotally mounted dispensing arm having a pipe restraining means.
  • a pipe restraining means In this way, an end of the coil of pipe stored in the frame can be received in the pipe restraining means and then, by varying the angular position of the dispensing arm, the pipe can be directed to the installation site as required. Since the pipe is securely restrained by the pipe restraining means, bending stresses can be safely induced as the pipe is dispensed.
  • the pipe may, for example, be dispensed directly into an excavation in a downwards direction.
  • the frame is typically formed of a plurality of elongate members defining uprights, side members and cross members, as is known in the art.
  • the dispensing arm is typically installed in the vicinity of a rear end of the frame and may be pivotally mounted to the frame (for example at a level corresponding substantially to the lowest point of a coil received in the frame).
  • the apparatus may further include means for locking the dispensing arm in any of a plurality of angular positions with respect to the frame. In this way, a pipe received in the pipe restraining means can be dispensed in various different directions.
  • the means for locking the dispensing arm may, for example, comprise a hydraulic actuator.
  • the hydraulic actuator may also serve to vary the angular position of the dispensing arm.
  • a hydraulic circuit may be provided for operating the hydraulic actuator.
  • the dispensing arm may comprise a pair of parallel side members, the side members being joined by cross members.
  • the pipe restraining means may then be carried by at least one of the cross members.
  • the pipe restraining means may be slidably mounted to the cross member. In this way, the position of the pipe restraining means can be laterally adjusted to correspond to the location of an end of the pipe.
  • the at least one cross member may be rotatably mounted to the side members, so that the pipe restraining means can be pivoted.
  • pairs of the cross members may be coupled together in a fixed, parallel relationship by plate-like end brackets, and the brackets pivotally mounted to the side members.
  • the pipe restraining means may simply be pivotally mounted to the at least one cross member.
  • the pipe restraining means may define a plurality of deflecting surfaces for at least partly surrounding the pipe, which may for example be rolling surfaces or sliding surfaces.
  • the pipe restraining means may comprise a pair of rollers arranged to face each other in the lateral direction.
  • the rollers may have profiled surfaces so that, when a pipe is threaded between the rollers its movement in transverse directions (that is to say directions perpendicular to the longitudinal direction of the pipe) is restricted or even prevented.
  • a spacing between the rollers may be adjustable so that pipes having different outer diameters can be accommodated by the pipe restraining means.
  • the dispensing arm may be provided with a second pipe restraining means.
  • the pipe restraining means described above is a first pipe restraining means and the second pipe restraining means is spaced from the first pipe restraining means in the longitudinal direction of the pipe.
  • the first and second pipe restraining means may be carried by different cross members of the dispensing arm.
  • the second pipe restraining means may be essentially the same as the first pipe restraining means and may therefore have one or more of the features of the first pipe restraining means described above.
  • a pair of longitudinally spaced apart pipe restraining means enables a pipe to be independently restrained at two locations. In this way, a dispensed portion of the pipe can be separated from the coil by cutting it between the two locations, such that the potentially dangerous release of bending stresses is avoided.
  • Another aspect of the invention relates to the handling of the coil of pipe in the apparatus.
  • at least one coil restraining means may be provided for bearing on an inner face of the coil while allowing it to rotate.
  • a coil restraining means of this type may prevent the coil from being pulled through the apparatus and may enable the coil to rotate as the pipe is dispensed.
  • Multiple coil restraining means may also serve to prevent the diameter of the coil becoming smaller as the pipe is dispensed.
  • Each coil restraining means may be arranged such that it can be moved into and out of the interior volume of the frame. In this way, a coil of pipe can be conveniently received into the interior volume before the coil restraining means is moved into place.
  • the position of the coil restraining means within the interior volume of the frame may be adjustable in the radial direction of the coil.
  • Each coil restraining means may comprise a roller carried on an arm.
  • the arm may be pivotally mounted to one side of the frame. Pairs of rollers may be coupled together and carried by a yoke arrangement.
  • the invention also provides a powered or unpowered vehicle comprising the apparatus described above.
  • vehicle may, for example, be an unpowered trailer for a road vehicle.
  • the trailer may have an open chassis for carrying the apparatus.

  • the pipe 3 may be dispensed in a downwards direction, for example directly into an excavation.
  • reverse bending stresses are induced as the pipe passes from the coil to the dispensing arm 17. These reverse stresses assist in destressing the pipe 3 as it is dispensed.
  • this operation can be performed at a position between the two roller assemblies 27. In this way, after cutting, the two free ends of the pipe adjacent the cut are held by a respective roller assembly 27. The hazardous release of bending stresses is thereby avoided.
  • the entire coil of pipe 3 is not dispensed from the trailer 1 at the installation site, the remaining coil of pipe can be transported away. In this case, the pipe is released from the second of the two roller assemblies 27, the dispensing arm 17 is returned to the vertical position, and the rear gates 31 are locked in the closed position, before the trailer 1 is towed away as required.
