(3) key points for operation and points for attention
cross slide way section of track spacing will accurately be fixed, and according to D beam lifting point, locates two root distances between plates, determines in advance section of track spacing, and corresponding with D beam suspension centre to guarantee chassis center, circuit both sides steel pipe column is corresponding with D beam suspension centre floor.
d beam 13 will synchronously, steadily, at a slow speed, be guaranteed safety during transverse-moving trolley on chassis.
measured in advance that chassis is traversing, vertical shift position, guaranteed that contraposition is accurate, carried out fast next procedure.
while adopting hydraulic jack jack-up D beam 13, two chassis can not be synchronous, first complete after a chassis, then carry out jack-up, the falling of another chassis, guarantees D beam 13 steady, safety.
because angle between cross slide way and vertical line is uncertain, therefore, after each transverse-moving trolley is located on vertical shift circuit, on chassis, make a check mark, determine the relative position relation of upper and lower chassis, the rapid-aligning when guaranteeing travelling backwards chassis.
when empty wagons vertical shift, traversing, jack-up, falling, chassis both sides must be established special messenger and be buttressed crossbeam steel tubular handrailing, guarantee that chassis is steady.
in 13 liftings of D beam, slippage, dropping process, whether firmly establish the steel pipe column bearing diagonal 12 that special messenger checks circuit both sides, guarantee that supporting steel tubing string 7 is firm.
will assume unified command of, act in agreement in 13 liftings of D beam, slippage, whereabouts, arrange special messenger two ends to hold up steady D beam 13 simultaneously, to reduce D beam 13, rock amplitude, guarantee safety.
before construction, check Chain block 8, Lever Blocks 11, guaranteed intactly, carried out emergent spare unit simultaneously.
In the genuine construction of southern station, Taiyuan synthetic job, this device security has successfully completed the installation and removal of 8 groups of D beams, and each engineering time basic controlling is between 1.5-2 hour.
