Abstract
Abstract ABSTRACT OF THE DISCLOSURE An apparatus for cleaning, priming and wrapping a pipeline and including a drive for advancing the apparatus along the pipe, a subframe mounted on a main frame, the subframe carrying a rotating brush and rotating round the pipe for cleaning the pipe, a priming station including an air blast manifold for removing loosened material, a priming section wherein a primer is flood-coated onto the pipe, and a drying section wherein drying air is blown against the pipe, the sections being separated by means of flexible diaphragms forming seals between the sections; a taping head orbiting the pipe and applying tape to the pipe in a helical path, and including means for controlling the tension of the tape; means for controlling the orbital speed of the taping head round the pipe as a function of the speed at which the apparatus advances along the pipeline.

Independent Claim
394 words
An apparatus for cleaning, priming and wrapping pipe comprising a frame for encircling said pipe and a plurality of wheels mounted on said frame for supporting said frame about said pipe so that said frame may move axially along said pipe; first, second and third bulkheads secured to said frame and longitudinally spaced along said frame; ring gear means encircling said pipe and positioned adjacent said second bulkhead; a plurality of first roller members mounted on said second bulkhead, the ring gear set up can be attached to either the first or second bulkhead and supporting said ring gear for rotation around said pipe; a ring member encircling said pipe and positioned adjacent said first bulkhead; a plurality of second roller members mounted on said first bulkhead and supporting said ring member for rotation around said pipe; cross members connecting said ring gear means and said ring member and forming therewith a rotatable subframe, motor means engaging said ring gear means for rotating said subframe around said pipe; a sprocket member fixed to said second bulkhead and encircling said pipe; one of said cross members comprising a shaft having first and second chain sprockets secured for simultaneous rotation thereon; a first drive chain engaging said sprocket member and said first chain sprocket; brush arms pivotally mounted on said shaft adjacent one end of said brush arm and brush means mounted adjacent the other end of said brush arm for rotation on said brush arm; a second drive chain engaging said second chain sprocket and said brush means, whereby revolution of said subframe causes rotation of said brush means; means for moving said brush arm toward or away From said pipe; a priming station positioned between said second and third bulkheads and comprising a pressurized air manifold encircling said pipe and having a plurality of nozzles For directing pressurized air against said pipe for removing material loosened by said brush means; a priming chamber having a pair of axially spaced pipe engaging seals and an annular primer manifold positioned between said seals for spraying primer onto said pipe and a drying chamber including an annular pressurized air chamber encircling said pipe and including nozzles for directing drying air onto the primer coated pipe; and a taping head mounted on said third bulkhead for orbiting around said pipe for wrapping tape onto the primer coated pipe.
Claim 2
Independent Claim
394 words
An apparatus for cleaning, priming and wrapping pipe comprising a frame for encircling said pipe and a plurality of wheels mounted on said frame for supporting said frame about said pipe so that said frame may move axially along said pipe; first, second and third bulkheads secured to said frame and longitudinally spaced along said frame; ring gear means encircling said pipe and positioned adjacent said second bulkhead; a plurality of first roller members mounted on said second bulkhead, the ring gear set up can be attached to either the first or second bulkhead and supporting said ring gear for rotation around said pipe; a ring member encircling said pipe and positioned adjacent said first bulkhead; a plurality of second roller members mounted on said first bulkhead and supporting said ring member for rotation around said pipe; cross members connecting said ring gear means and said ring member and forming therewith a rotatable subframe, motor means engaging said ring gear means for rotating said subframe around said pipe; a sprocket member fixed to said second bulkhead and encircling said pipe; one of said cross members comprising a shaft having first and second chain sprockets secured for simultaneous rotation thereon; a first drive chain engaging said sprocket member and said first chain sprocket; brush arms pivotally mounted on said shaft adjacent one end of said brush arm and brush means mounted adjacent the other end of said brush arm for rotation on said brush arm; a second drive chain engaging said second chain sprocket and said brush means, whereby revolution of said subframe causes rotation of said brush means; means for moving said brush arm toward or away From said pipe; a priming station positioned between said second and third bulkheads and comprising a pressurized air manifold encircling said pipe and having a plurality of nozzles For directing pressurized air against said pipe for removing material loosened by said brush means; a priming chamber having a pair of axially spaced pipe engaging seals and an annular primer manifold positioned between said seals for spraying primer onto said pipe and a drying chamber including an annular pressurized air chamber encircling said pipe and including nozzles for directing drying air onto the primer coated pipe; and a taping head mounted on said third bulkhead for orbiting around said pipe for wrapping tape onto the primer coated pipe.
Claim 3
Dependent Claim
