Abstract
A wire saw apparatus comprises: a first pulley system from which a wire is withdrawn toward a structure to be cut; a second pulley system into which the wire is introduced from the structure; a first dust collection pipe unit provided to surround the wire between an end part at which surrounding of the structure by the wire ends and a part at which the wire is introduced into the first pulley system; and a second dust collection pipe unit provided to surround the wire between a start part at which surrounding of the structure by the wire starts and a part at which the wire is withdrawn from the second pulley system.
Claims15
A wire saw apparatus configured to collect foreign substances generated during a dry cutting process, the wire saw apparatus comprising:
- a first pulley system configured to feed a wire to a structure to be cut;
- a second pulley system configured to receive the wire from the structure;
- a first dust-collecting pipe unit configured to surround the wire between a point of the wire that is separated from the structure after surrounding the structure and a point of the wire that enters the first pulley system;
- and
- a second dust-collecting pipe unit configured to surround the wire between a point of the wire that reaches the structure to surround the structure and a point of the wire that escapes from the second pulley system,
- wherein at least one of the first dust-collecting pipe unit or the second dust-collecting pipe unit comprises a first pipe and a second pipe having different diameters from each other, and the first pipe and the second pipe are connected to each other so as to be movable in a horizontal direction in a state in which at least a portion of the first pipe is inserted into the second pipe.
A wire saw apparatus configured to collect foreign substances generated during a dry cutting process, the wire saw apparatus comprising:
- a first pulley system configured to pass a wire introduced thereinto from one end of a cover provided so as to seal a cut portion of a structure to be cut;
- at least one main roller configured to allow the wire that has passed through the first pulley system to rotate along an outer circumferential surface thereof using power;
- and
- at least one driving roller configured to feed the wire introduced thereinto from the at least one main roller to a second pulley system,
- wherein the second pulley system passes the wire introduced thereinto from the at least one driving roller to feed the wire to an opposite end of the cover, and
- wherein a member containing stone powder and a silicon component is attached to an outer circumferential surface of at least one roller among the at least one main roller, the at least one driving roller, at least one roller provided in the first pulley system, and at least one roller provided in the second pulley system.
