Abstract

A boom is made of telescoping boom sections. A movable cutting nozzle is on the boom and sprays water. In one embodiment, the boom is coupled to the climber section of a platform that climbs a tower. A further beam is mounted on the other side of the hydraulic elevating platform and carries a movable power pack/counterweight. In a second embodiment of the present invention, the device is oriented horizontally and the platform moves horizontally on a rail. In this configuration, the elongated boom has a distal end protruding over the top edge of a dam or other structure. Depending vertically from the boom is another vertical boom carrying the cutting nozzle. This boom travels on the outer boom section of the elongated boom and extends downwardly a distance to allow the device to treat the concrete surface downward from the top edge of the structure.

Dependent claims

A hydrodemolition robot, comprising:

a) an elongated tower having first and second ends and on which is mounted an elevating platform, said elevating platform having first and second opposed sides and being movable on said tower from its first end to its second end;
b) a first boom connected to said first side of said platform, said first boom including a first boom section attached to said first side of said platform and a second boom section telescopically mounted on said first boom section;
c) a nozzle mounted on said second boom section and connected to a source of pressurized material;
d) a second boom connected to said second side of said platform and a carriage on said second boom movable between first and second ends of said second boom;
e) a power pack on said carriage and including controls for operation of said robot;
f) said carriage and power pack also comprising a counterweight to balance weight distribution of said robot to maintain a center of gravity at a location between said sides of said platform, said carriage being moved based upon a degree of extension of said second boom section with respect to said first boom section to maintain said center of gravity at said location.

A hydrodemolition robot, comprising:

a) an elongated tower having first and second ends and on which is mounted an elevating platform, said elevating platform having first and second opposed sides and being incrementally movable on said tower from its first end to its second end;
b) a first boom connected to said first side of said platform, said first boom including a first boom section attached to said first side of said platform and a second boom section telescopically mounted on said first boom section;
c) a nozzle movably mounted on said second boom section and connected to a source of pressurized water;
d) a second boom connected to said second side of said platform and a carriage on said second boom movable between first and second ends of said second boom;
e) a power pack and weight on said carriage and said power pack including controls for operation of said robot;
f) said carriage, weight, and power pack also comprising a counterweight to balance weight distribution of said robot to maintain a center of gravity at a location between said sides of said platform, said carriage being moved based upon a degree of extension of said second boom section with respect to said first boom section to maintain said center of gravity at said location.
