jack prepares: hydraulic jack is transported to circuit vertical shift place in advance, installs oil pipe and oil pump, hand-operated jack is fixed on chassis in advance.
(2) work flow in
traversing: cross slide way connects, follow closely solid rail → transverse-moving trolley to vertical shift circuit place → rotating lower vehicle frame 2, micro-moving stage car, the urgent horizontal road wheel of adjustment wheel direction → timber wedge, fixed lateral position;
vertical shift: at upper strata vehicle frame 1 outer side-lower, the jack-up chassis of hydraulic jack → is successively installed, extracts cross slide way, return back to top to fall on vertical shift railway → vertical shift chassis kills lengthwise rows travelling wheel, fixing lengthwise position to reinforcing place of D beam, timber wedge;
horizontal sliding, whereabouts D beam 13: swing bolster 5 to horizontal path direction, untie the stringing hoop → reinforcing of D beam 13 two ends, connecting cross beam 5 and circuit supported on both sides steel pipe column 7 → moving slider 10, be connected Chain block 8, bracket earrings 9 → manually pull successively Chain block 8 hoists D beam 13, make D beam 13 end depart from chassis → artificial to pull on crossbeam 5 top successively outside Lever Blocks 11 slippage D beam 13 to steel sleeper → manually draw Chain block 8, whereabouts D beam 13;
travelling backwards chassis: after D beam 13 is in place, travelling backwards slide block 10, swing bolster 5 to parallel circuit direction → fixed cross beam 5, install crossbeam steel tubular handrailing → vertical shift chassis to cross slide way place → establish special messenger to hold up steady crossbeam steel tubular handrailing, utilize artificial jack-up chassis → installations of hand-operated jack, connect cross slide way → fallings jack, make chassis to fall on cross slide way → outside transverse-moving trolley to circuit outside, timber wedge kills, fixes chassis.
(3) key points for operation and points for attention
cross slide way section of track spacing will accurately be fixed, and according to place two, D beam lifting point root distance between plates, determines section of track spacing in advance, and to guarantee that chassis center is corresponding with D beam suspension centre, circuit both sides steel pipe column is corresponding with D beam suspension centre floor.
d beam 13 synchronously, steadily, at a slow speed, will guarantee safety during transverse-moving trolley on chassis.
measure that chassis is traversing, vertical shift position in advance, guaranteed that contraposition is accurate, carry out next procedure fast.
when adopting hydraulic jack jack-up D beam 13, two chassis can not be synchronous, after first will completing a chassis, then carries out jack-up, the falling of another chassis, guarantees that D beam 13 is steady, safety.
because between cross slide way and vertical line, angle is uncertain, therefore, each transverse-moving trolley is located in after on vertical shift circuit, and chassis makes a check mark, and determines the relative position relation of upper and lower chassis, to guarantee rapid-aligning during travelling backwards chassis.
when empty wagons vertical shift, traversing, jack-up, falling, chassis both sides must establish special messenger to buttress crossbeam steel tubular handrailing, guarantee that chassis is steady.
d beam 13 promotes, slippage, in dropping process, special messenger be established to check, and whether the steel pipe column bearing diagonal 12 of circuit both sides is firm, guarantees that supporting steel tubing string 7 is firm.
d beam 13 promotes, will assume unified command of, act in agreement in slippage, whereabouts, arranges special messenger two ends to hold up steady D beam 13 simultaneously, rocks amplitude, guarantee safety to reduce D beam 13.
check Chain block 8, Lever Blocks 11 before construction, guaranteed intact, carry out emergent spare unit simultaneously.
In the construction of southern station, Taiyuan synthetic job tunnel, this device security successfully completes the installation and removal of 8 groups of D beams, and each engineering time basic controlling is in the 1.5-2 little time.
