operation principle
G, transverse cuts: by the first elevating ram 2, will on fixed head 27, draw, fixed head 27 rises to extreme higher position by cast-cutting saw 5, now locking cylinder 17 is locked frame 1, start electric rotating machine 4, electric rotating machine 4 drives cutting motor 7 to rotate, cast-cutting saw 5 is forwarded to and prestressed cored slab upright position, cast-cutting saw 5 arrives behind precalculated position, locked cylinder 6 work are locked rotating shaft 26, cast-cutting saw 5 is moved to high order end, cooling fluid is ready, starts cutting motor 7 drive cast-cutting saw 5 rotations by program.Cast-cutting saw 5 drops to prestressed cored slab contact position starts working, and depth of cut can be presented on instrument board in real time.Arrive after the predetermined cuts degree of depth, support 29 is under the drive of transverse hydraulic motor 10, and low speed, moves right evenly.To moving to low order end, cast-cutting saw 5 quits work, and cast-cutting saw 5 is risen to extreme higher position, completes transverse cuts one time.
H, longitudinally cutting: device is longitudinally moved to precalculated position, and cast-cutting saw 5 rises to extreme higher position, and locked cylinder 6 unclamps and removes coupling mechanism force, start electric rotating machine 4 cast-cutting saw 5 gone to and prestressed cored slab parallel position, locked cylinder 6 lockings.Brake cylinder 9 is opened, saw blade laterally moves to precalculated position, brake cylinder 9 lockings, locking cylinder 17 with timer is opened, by program, start cutting motor 7 and drive cast-cutting saw 5 rotations, open cooling fluid, cast-cutting saw 5 drop to prestressed cored slab contact position after, cast-cutting saw 5 declines and starts cutting work, depth of cut is by programme-control and be presented on instrument board, saw blade arrives after desired depth, frame 1 is under the drive of longitudinal hydraulic motor 15, low speed and vertically moving evenly, device starts longitudinal cutting work, to longitudinal cutting end point, locking cylinder 17 locking frames 1, cast-cutting saw 5 rises to extreme higher position, complete the work of once longitudinally cutting.
I, oblique cutting: device moves to behind precalculated position, cast-cutting saw 5 rises to extreme higher position, and locked cylinder 6 unclamps and removes coupling mechanism force, starts electric rotating machine 4 cast-cutting saw 5 is gone to being predetermined angular with prestressed cored slab, then locked cylinder 6 lockings.After cutting angle is determined, brake cylinder 9 is opened, support 29 laterally moves to precalculated position, locking cylinder 17 with timer is opened, cutting motor 7 drives cast-cutting saw 5 rotations, after cooling fluid is opened, cast-cutting saw 5 drops to prestressed cored slab contact position starts working, and depth of cut shows in real time on instrument board.When depth of cut reaches desired depth, under driving, install low speed and advance evenly in transverse hydraulic motor 10 and longitudinal hydraulic motor 15, until reach home, cast-cutting saw 5 rises to extreme higher position, completes once oblique cutting.
J, fluting cutting: first cast-cutting saw 5 and grooving saw 14 are risen to extreme higher position, again locking cylinder 17 is opened, and startup fluting motor 13 drives grooving saws 14 rotations, open cooling water, grooving saw 14 is dropped to and prestressed cored slab contact position, start cutting, cut to predetermined extreme lower position, the second elevating ram 12 lockings, frame 1 is under the drive of longitudinal hydraulic motor 15 afterwards, slowly advance, until cutting end point position, grooving saw 14 rises to extreme higher position, and cooling water is closed, locking cylinder 17 frame 1 that is locked, completes once fluting cutting.
K, advance fast: when device does not cut work, require it to walk fast, to increase work efficiency, reduce unnecessary time waste.Longitudinally the oil feeding line of hydraulic motor 15 is comprised of two independent sectors, and when cast-cutting saw 5 and grooving saw 14 are during all in extreme higher position, longitudinally hydraulic motor 15 is by high speed oil supply loop fuel feeding, otherwise, by low speed oil supply loop fuel feeding, thereby realize, not work be quick walking, slowly walks in operating room.
