System for removing and replacing fire-tubes
View Patent ↗A system for removing and replacing fire-tubes. The system can include a powered system, a fire-tube puller coupled to said powered system. The fire-tube puller has a puller back which is coupled to a plug rest. A plug rest is approximately perpendicular to the puller back, and the fire-tube will rest upon the plug rest when the fire-tube is being removed or installed. The system can also include a stack adjuster which is coupled to the plug rest. The stack adjuster can couple to a stack so as to reposition the stack.
1. A fire-tube removal and installation system comprising: an arm with a distal end adapted to move in a three dimensional direction, a puller back having a distal side and a proximal side, the proximal side being connected to the distal end of the arm by double hinges; at least one plug rest, wherein the at least one plug rest is parallel to another plug rest, and have a proximal end and a distal end, the proximal end being connected to the distal side of the puller back, the at least one plug rest further being adapted for insertion into a fire-tube; a stack adjuster configured to be connected to the distal end of the plug rest and adapted to decouple a removable stack from the fire-tube extending from a fire-tube exhaust of the fire-tube and a powered system adapted to move the arm in a three dimensional direction.
2. The system of claim 1 , wherein the puller back further comprises two double hinges.
3. The system of claim 2 , wherein the puller back is adapted to be removably coupled to the fire-tube exhaust.
4. The system of claim 3 , wherein said puller back comprises a void located at its top, and wherein said puller back further comprises a puller back coupler which is used to engage with a portion of a fire-tube, and wherein said stack adjuster comprises a stack coupler which is used to engage a stack.
5. The system of claim 1 , wherein the puller back is capable of being rotated in three dimensions.
6. The system of claim 1 , wherein the puller back is approximately perpendicular to said at least one plug rest.
7. The system of claim 1 , wherein the powered system moves the arm hydraulically.
8. The system of claim 7 , wherein the powered system moves the arm hydraulically to be tilted, angled, and positioned as desired.
9. The system of claim 1 , wherein the powered system moves the arm pneumatically.
10. The system of claim 9 , wherein the powered system moves the arm pneumatically to be tilted, angled, and positioned as desired.
11. The system of claim 1 , wherein the powered system comprises an arm adapted to position the at least one plug rest for removal or installation of a vertically oriented fire-tube.
12. The system of claim 1 , wherein the powered system comprises an arm is adapted to position the at least one plug rest for removal or installation of a horizontally oriented fire-tube.
13. The system of claim 1 , further comprising a coupler secured to the puller back and extending distally from the puller back, the coupler adapted to secure the fire-tube exhaust.
14. The system of claim 1 , wherein the stack adjuster is removable.
15. The system of claim 1 , wherein the stack adjuster comprises an adjuster lip and an adjuster body.
16. The system of claim 1 , wherein the powered system is adapted to lift the fire-tube having a weight up to 6000 lbs.
17. The system of claim 1 , further comprising a mobile system which transports said power system, said fire-tube puller, and fire-tube.
18. The system of claim 1 , wherein the puller back is welded to the at least one plug rest.
19. The system of claim 1 , wherein the puller back and the at least one plug rest is made as a single piece.
20. The system of claim 1 , wherein the at least one plug rest is coupled to a front face of the puller back.
