Pipe lining apparatus transport assemblies
A pipe lining apparatus transport assembly having one or more positioning mechanisms for maintaining the orbiting operational components of the pipe lining apparatus in a concentric relationship with the pipe, the positioning mechanisms including alone or in combination extension/retraction mechanisms, track set rotational mechanisms, articulating joint mechanisms and/or linear translation mechanisms.
1. A pipe lining apparatus comprising:
operational components applying lining material and/or reinforcing filaments to an interior of a pipe;
a transport assembly comprising two track sets, each said track set comprising a pair of laterally separated tracks connected to at least one extraction/retraction mechanism, said track sets connected to said operational components;
at least one linear translation mechanism moving one or more of said track sets laterally relative to said operational components; and
a single track set rotational mechanism connected to each said track set and having a vertical axis, whereby said track sets rotate about said vertical axis relative to said operational components.
2. The apparatus of claim 1 , wherein said tracks are connected to said extension/retraction mechanism by a rocker mechanism.
3. The apparatus of claim 1 , wherein said track sets are connected to a bridging member.
4. The apparatus of claim 3 , further comprising an articulating joint mechanism dividing said bridging member into two articulating segments.
5. The apparatus of claim 1 , wherein each of said extension/retraction mechanisms and each of said track set rotational mechanisms operate independently of each other.
6. The apparatus of claim 1 , wherein each of said extension/retraction mechanisms, each of said track set rotational mechanisms, and each of at least one linear translation mechanism operate independently of each other.
7. The apparatus of claim 1 , wherein said operational components are positioned between said track sets.
8. The apparatus of claim 4 , wherein one of said track sets is positioned between said operational components and the other of said track sets.
9. A pipe lining apparatus comprising:
operational components applying lining material and/or reinforcing filaments to an interior of a pipe, said operational components having a central axis, wherein said operational components apply said lining material and/or reinforcing filaments to the interior of the pipe in an orbital manner centered on said central axis;
a transport assembly comprising two track sets, each said track set comprising a pair of laterally separated tracks connected to at least one extraction/retraction mechanism, said track sets connected to said operational components;
a track set rotational mechanism connected to each said track set and having a vertical axis, whereby said track sets rotate about said vertical axis relative to said operational components;
at least one linear translation mechanism moving one or more of said track sets laterally relative to said central axis of said operational components;
wherein said transport assembly adjusts the position of said central axis of said operational components within the pipe such that said central axis is concentric with said pipe.
10. The apparatus of claim 9 , wherein said tracks are connected to said extension/retraction mechanism by a rocker mechanism.
11. The apparatus of claim 9 , wherein said at least one extraction/retraction mechanism comprise telescoping sleeve members.
12. The apparatus of claim 10 , wherein said at least one extraction/retraction mechanism comprises telescoping sleeve members.
13. The apparatus of claim 9 , wherein said at least one linear translation mechanism comprises a turn screw actuated by a motor, said turn screw retained by a mounting bracket connected to said operational components, and a platform connected to said turn screw and to at least one of said track sets, whereby rotation of said turn screw moves said turn set laterally relative to said central axis.
14. The apparatus of claim 10 , wherein said at least one linear translation mechanism comprises a turn screw actuated by a motor, said turn screw retained by a mounting bracket connected to said operational components, and a platform connected to said turn screw and to at least one of said track sets, whereby rotation of said turn screw moves said turn set laterally relative to said central axis.
15. The apparatus of claim 11 , wherein said at least one linear translation mechanism comprises a turn screw actuated by a motor, said turn screw retained by a mounting bracket connected to said operational components, and a platform connected to said turn screw and to at least one of said track sets, whereby rotation of said turn screw moves said turn set laterally relative to said central axis.
16. The apparatus of claim 12 , wherein said at least one linear translation mechanism comprises a turn screw actuated by a motor, said turn screw retained by a mounting bracket connected to said operational components, and a platform connected to said turn screw and to at least one of said track sets, whereby rotation of said turn screw moves said turn set laterally relative to said central axis.
17. The apparatus of claim 9 , wherein each of said extension/retraction mechanisms and each of said track set rotational mechanisms operate independently of each other.
18. The apparatus of claim 9 , wherein each of said extension/retraction mechanisms, each of said track set rotational mechanisms, and each of said at least one linear translation mechanism operate independently of each other.
