Aerial pipe arrangement and method of aerially arranging pipes

Abstract

The pipe arrangement for feeding fluid to a fluid-receiver from a fluid-supplier through a pipe, includes a wire tensioned between a first support and a second support, a hollow fluid-feeding pipe extending between the first and second supports, and a device for allowing the fluid-feeding pipe to hang from the wire. The fluid-feeding pipe is comprised of a plurality of fundamental pipes capable of being connected to one another. A second fundamental pipe connected to a first fundamental pipe can extend and contract axially thereof relative to the first fundamental pipe, and can further bend obliquely relative to the first fundamental pipe.

Claims

1. An aerial pipe arrangement for feeding fluid to a fluid-receiver from a fluid-supplier through a pipe, comprising: a wire tensioned between a first support and a second support;a hollow fluid-feeding pipe extending between said first and second supports; anda hanger for allowing said fluid-feeding pipe to hang from said wire,wherein said fluid-feeding pipe is comprised of a plurality of fundamental pipes capable of being connected to one another,a second fundamental pipe connected to a first fundamental pipe can extend and contract axially thereof relative to said first fundamental pipe, and can further bend obliquely relative to said first fundamental pipe,said first fundamental pipe is formed at one end thereof with an increased-radius portion having an increased inner radius, and a flange formed continuous to said increased-radius portion,said second fundamental pipe is formed with at least one projection located remote from an end of said second fundamental pipe,said first and second fundamental pipes are connected to each other through a movable flange,said movable flange has an inner diameter to fit around said second fundamental pipe,said movable flange is formed at an inner edge thereof with a cut-out through which said projection can pass, andwhen said first and second fundamental pipes are connected to each other through said movable flange, said movable flange is connected to said flange of said first fundamental pipe such that said projection and said cut-out are not in alignment with each other.

2. The aerial pipe arrangement as set forth in claim 1, further comprising a first hollow supply-pole standing on the ground, wherein said first hollow supply-pole defines said first support, and is connected to said fluid-supplier, andsaid fluid supplied from said fluid-supplier is fed to said fluid-receiver through said first hollow supply-pole and said fluid-feeding pipe in this order.

3. The aerial pipe arrangement as set forth in claim 1, further comprising a second hollow supply-pole standing on the ground, wherein said second hollow supply-pole defines said second support, and is connected to said fluid-receiver, andsaid fluid supplied from said fluid-supplier is fed to said fluid-receiver through said fluid-feeding pipe and said second hollow supply-pole in this order.

4. The aerial pipe arrangement as set forth in claim 2, further comprising a second hollow supply-pole standing on the ground, wherein said second hollow supply-pole defines said second support, and is connected to said fluid-receiver, andsaid fluid supplied from said fluid-supplier is fed to said fluid-receiver through said fluid-feeding pipe and said second hollow supply-pole in this order.

5. The aerial pipe arrangement as set forth in claim 4, further comprising at least one support-pole standing on the ground between said first and second hollow supply-poles for supporting said fluid-feeding pipe therewith.

6. The aerial pipe arrangement as set forth in claim 5, wherein said support-pole has a fundamental pipe to which said fluid-feeding pipe can be connected to, said fluid-feeding pipe being connected to said fundamental pipe.

7. The aerial pipe arrangement as set forth in claim 1, further comprising at least one branch pipe, said branch pipe being connected to said fluid-feeding pipe to partially separate said fluid from said fluid-feeding pipe thereinto.

8. The aerial pipe arrangement as set forth in claim 7, wherein said branch pipe is comprised of a bellows pipe composed of plastic.

9. A method of aerially arranging pipes for feeding fluid to a fluid-receiver from a fluid-supplier, comprising: tensioning a wire between a first support and a second support; andhanging a hollow fluid-feeding pipe extending between said first and second supports, from said wire,wherein said fluid-feeding pipe is comprised of a plurality of fundamental pipes capable of being connected to one another,a second fundamental pipe connected to a first fundamental pipe can extend and contract axially thereof relative to said first fundamental pipe, and can further bend obliquely relative to said first fundamental pipe,said first fundamental pipe is formed at one end thereof with an increased-radius portion having an increased inner radius, and a flange formed continuous to said increased-radius portion,said second fundamental pipe is formed with at least one projection located remote from an end of said second fundamental pipe,said first and second fundamental pipes are connected to each other through a movable flange,said movable flange has an inner diameter to fit around said second fundamental pipe,said movable flange is formed at an inner edge thereof with a cut-out through which said projection can pass, andwhen said first and second fundamental pipes are connected to each other through said movable flange, said movable flange is connected to said flange of said first fundamental pipe such that said projection and said cut-out are not in alignment with each other.

10. The method as set forth in claim 9, further comprising: standing a first hollow supply-pole on the ground, said first hollow supply-pole defining said first support; andconnecting said first hollow supply-pole to said fluid-supplier.

11. The method as set forth in claim 9, further comprising: standing a second hollow supply-pole on the ground, said second hollow supply-pole defining said second support; andconnecting said second hollow supply-pole to said fluid-receiver.

12. The method as set forth in claim 10, further comprising: standing a second hollow supply-pole on the ground, said second hollow supply-pole defining said second support; andconnecting said second hollow supply-pole to said fluid-receiver.

13. The method as set forth in claim 12, further comprising standing at least one support-pole between said first and second hollow supply-poles for supporting said fluid-feeding pipe therewith.

14. The method as set forth in claim 9, further comprising connecting at least one branch pipe to said fluid-feeding pipe to partially separate said fluid from said fluid-feeding pipe into said branch pipe.
