Abstract
The invention in question is a repairing machine, which is suited to repairing damaged conduits which are inaccessible for repair work. This repairing machine is remote-controlled and monitored with television cameras. At the head of the driving carriage, various devices, which are necessary for the repairs, can be attached to a motor-driven rotatable toolhead. A simple construction of the movable head has made it possible to accomplish all of the necessary movements with uncomplicated mechanics, and at the same time, to forego a tedious slide coupling for the control lines without letting them get tangled with the device. Therefore, with this invention, the production costs for the whole device could be lowered and, likewise, the proneness to repairs could be reduced.
Claims7
A remote control device for repairing and/or sealing conduits, said device comprising:
- a wheeled undercarriage, said undercarriage being movable into the conduits and having a central longitudinal axis;
- a rotatable hollow shaft arranged within said undercarriage and concentric to said undercarriage, said shaft being rotatable around said central axis;
- a motor for driving the rotational movement of said shaft;
- and
- a plurality of mounting components for interchangeably mounting the desired repairing and/or sealing equipment, said components being fitted at one end of said shaft, the supply lines for the repairing and/or sealing equipment being torsionally flexible and at least one end thereof being located within said shaft, means providing for at least one of said mounting components to be movable radially from the shaft within the conduit to effect the repair and/or sealing work.
