Abstract
A guide pulley base for wire saw having a pair of main pulleys on the same plane, a pair of guidance pulleys in parallel to each other in such a way that each outer periphery of the guidance pulley is in contact with each parallel tangent line contacting with each outer periphery of each main pulley from the opposing side of the main pulleys, and further at need, a pair of second guidance pulleys, a pair of second main pulleys and an auxiliary pulley. The guide pulley base for wire saw is arranged between a wire drive unit and an object to be cut for guiding a cutting wire and smoothly turning the wire travel direction when an object to be cut such as ferroconcrete structure in a building, a bridge, a subway, etc. is cut off partially.
Claims8
A guide pulley base for wire saw comprising a support frame, a pair of main pulleys rotatably supported by the support frame a distance apart from each other on the same plane, and a pair of guidance pulleys rotatably supported by the support frame in parallel to each other on separate planes and in such a way that the outer periphery of each guidance pulley is in contact with a tangent line through the outer periphery of each main pulley wherein each of the guidance pulleys are disposed perpendicularly or at an oblique angle with each of the main pulleys.
A guide pulley base for wire saw comprising a support frame, a pair of main pulleys rotatably supported by the support frame a distance apart from each other on the same plane, and a pair of guidance pulleys rotatably supported by the support frame in parallel to each other in such a way that the outer periphery of each guidance pulley is in contact with a tangent line through the outer periphery of each main pulley, wherein a cover member is disposed along the outer periphery of one of the two guidance pulleys through pivotal arms sandwiching both side surfaces of said one pulley.
