Abstract:
A power boiler tube removal tool assembly for shearing and bending gap metal located in a boiler tube segment, and comprising:a rigid tool frame;a pressurized-fluid actuator carried by said tool frame;a shear block element secured to and carried by said tool frame and having a shear cavity and an anvil partially defining said shear cavity;a rotatable shear blade element pivotally carried by said shear block element and cooperating with said shear block element shear cavity; anda cam element slidably supported on said rigid tool frame, connected to said pressurized-fluid actuator for reciprocation, and co-operating with said rotatable shear blade element,said cam element causing rotation of said rotatable shear blade element within said shear block element shear cavity when said pressurized-fluid actuator is actuated sufficient to shear and inwardly bend gap metal from a co-operating boiler tube segment about said anvil.
