Claims
- 1. A tube cleaning device, comprising:
- at least one water jet lance,
- means for extending and retracting said lance,
- support means for said lance including an elongated slotted hollow member in which said lance is slidably positioned therein to prevent bending collapse of said lance when subjected to end loading, and
- means for supplying water under pressure to said lance, said water supply means including a manifold block having means therewith for distributing said pressurized water to said lance and a duct mounted with said manifold block and said lance for conducting said pressurized water therebetween, wherein said elongated slotted hollow member having a slot formed therein slidably receives said duct adjacent thereto said slot.
- 2. A tube cleaning device according to claim 1, wherein said support means further includes:
- a tray for supporting said elongated slotted hollow member therewith.
- 3. The tube cleaning device according to claim 2, further including:
- a carriage mounted for movement on said tray for supporting said manifold block for movement therewith.
- 4. A tube cleaning device, comprising:
- a frame including opposing channel members adapted for alignment with the tubes of a heat exchanger or the like;
- a tray mounted with said frame, said tray having a plurality of support tubes mounted therewith, said support tubes having slots extending longitudinally thereof;
- a carriage mounted on said channels for movement along said channels;
- a manifold mounted for movement with said carriage; and
- a plurality of water jet lances mounted in said support tubes and affixed to said manifold through a plurality of ducts which extend from said manifold through said slots into fluid connection with said lances whereby said lances are mounted for movement with respect to said tray and said support tubes.
