Detailed description of the invention
In order to there be understanding clearly to technical characteristic of the present invention, object and effect, now contrast accompanying drawing and describe the specific embodiment of the present invention in detail.
Top of gas cabinet hydraulic pressure lift method of the present invention comprises the following steps as shown in figs 1 to 6:
1, cabinet top lifting device assembling
1.1 install 24 pillar stiffeners 4 respectively at 24 gas chamber column tops.Capital is provided with radial inflow bracket 10.Pillar stiffener 4, with the blanking of final section structural column, cuts off after being used to complete.Every root pillar stiffener 4 installs a lifting hydraulic support 3 above.The sidewall 7 of cabinet is provided with wind truss.
24 hydraulic supports 3 are in place by 1.2, loose clip type jack 2 is installed on the upper mounting plate of hydraulic support 3, fixes with M20 bolt, lower dop 2.14 is installed on the lower platform of hydraulic support 3, fixes with M16 bolt.Jack 2 comprises upper chuck 2.1, oil cylinder 2.2, upper oil nozzle 2.3, lower oil nozzle 2.4, dop spring 2.5, end cap 2.6, fixture block 2.7, fixture block seat 2.8, coupling link 2.9, loose snap ring 2.10, loose card screw rod 2.11, loose card nut 2.12, limit base 2.13, lower dop 2.14, push rod 2.15.
Loose card nut 2.12 conter clockwise of upper and lower dop is upwards threaded to summit by 1.3, makes upper and lower dop be in loose card-like state.
Lower dop 2.14 lower end of the steel strand 6 of 52 meters long from hydraulic support 3 lower end upwards penetrates by 1.4, upwards always through upper chuck 2.1, is advisable to expose upper chuck 200mm.
1.5 are threaded to summit by under loose card nut 2.12 clockwise direction of upper and lower dop, make upper and lower dop be in pintle hook lock state.
All jacks 2 and steel strand 6 are in place by 1.6 successively.
Steel strand 6 lower end is penetrated the suspension centre of fastening means 9 by 1.7, and with ground tackle 11 anchoring jail, a suspension centre installs 2 ground tackles 11, is connected on cabinet top 8 with steel ingot chock 12 with fastening means 9, and the two ends of chock 12 have steel wire buckle 13 spacing.Successively by 48 steel strand 6 anchoring jails.
Because the hoisting speed of the steel strand of 2 on each suspension centre 6 can not be completely the same, if take to promote lower seat directly to weld with ring flat-plate, so when 2 steel strand 6 hoisting speeies of same suspension centre are not quite identical, this 2 steel strand 6 stressed also just different, even differ greatly, can potential safety hazard be brought thus.In order to address this problem, adopt chock 12 to be hinged to each suspension centre in cabinet top, even if 2 steel strand hoisting speeies of same like this suspension centre are inconsistent, the stressed of these 2 steel strand is also uniform, thus solves the stability under loading sex chromosome mosaicism promoting suspension centre.
Two hydraulic power units are lifted on 38.1 meters of platforms by 1.8, at 144 meters of circumferentially uniform 2 points, then are in place by hydraulic oil radiator.The oil pipe of diameter 16*6.5 rice is picked out from hydraulic power unit.Jack and oil main line are coupled together by the branch oil pipe of diameter 10*4 rice, under jack, oil circuit can only communicate with working connection one, and on jack, another of oil circuit and working connection communicates.Successively the oil circuit of two hydraulic power units is in place.
Hydraulic power unit is connected three casees quadded cables by 1.9, is coupled together by the electromagnetic valve cable on two hydraulic power units, controls for unified.Mix up the position of rotating and rise and fall.
1.10 by hydraulic power unit pressure testing one by one, gets rid of leakage of oil point.
1.11 start hydraulic power unit, the pressure of two hydraulic power units is adjusted to 1-2Mpa, button is adjusted to hoisting position, be adjusted to lowering position every several seconds, back and forth several times, all steel strand all adjusted the same pulling force, again jack is adjusted to stroke bottom, prepares to promote.
2, the examination of cabinet top promotes
Suspend when being promoted to one meter of height, check all fixing ground tackles 11, locker, jack 2 whether flexibility and reliability one by one, whether the oil pipe of hydraulic efficiency pressure system, valve, electric switch be safe and reliable.Measure cabinet top Integral synchronous situation, guarantee no problem after treat within second day, to continue to promote.
3, formal circularly enhancing is to design height
After top of gas cabinet examination lifting confirmation is safe and reliable, formally promote.
After steel strand 6 insert jack 2, make upper chuck 2.1, lower dop 2.14 in running order, when pump fuel feed, pressure oil enters in cylinder body from lower oil nozzle 2.4, due to upper chuck 2.1 auto lock steel strand 6, this at present dop 2.14 unclamp, under oil pressure effect, piston rises and is upwards lifted with load by steel strand 6, when piston rises a full stroke gear pump stop control lever, load stops rising, and completes lifting process.During oil return, pressure oil enters from upper oil nozzle 2.3, this at present dop 2.14 lock, steel strand 6 transfixion, under the effect of oil pressure, return piston stroke, hydraulic oil is discharged from lower oil nozzle 2.4.So far, a lifting process is completed.After completing jack 2 one strokes, locked lower dop 2.14, unclamps upper chuck 2.1, and recalls to previous status by upper chuck 2.1 and push rod 2.15; Circularly enhancing successively, until it is high to be promoted to cabinet top mark.In Fig. 4, label 8 indication is the position on cabinet top to be hoisted, and label 1 is the position on the cabinet top promoted.
Often promote 2m in lifting process to check and once fix ground tackle 11, locker, jack 2 whether flexibility and reliability, whether the oil pipe of hydraulic efficiency pressure system, valve, electric switch be safe and reliable, measure cabinet top Integral synchronous situation, please adjust in time when error is large, and pinpoint the problems and will report without delay.
During lifting cabinet top, disposable cabinet top is risen to below design and installation height 100mm.When promoting from cabinet top setting height(from bottom) 100mm, slowly must promote, namely adjust the design height installed on cabinet top, adjust cabinet top surrounding from side plate size.
4, cabinet top is fixed
When cabinet apex distance is from 100mm below design and installation absolute altitude, slowly promotes, make the laminating of cabinet top surrounding connecting panel and side plate connecting panel as far as possible, then reinforcement of weld gusset immediately, cabinet top is fixed.In welding process, bont must remain uniform force state, by locked for dop under jack 2.14.Dop 2.14 under jack can be opened after band weld seam passed examination.
By reference to the accompanying drawings embodiments of the invention are described above; but the present invention is not limited to above-mentioned detailed description of the invention; above-mentioned detailed description of the invention is only schematic; instead of it is restrictive; those of ordinary skill in the art is under enlightenment of the present invention; do not departing under the ambit that present inventive concept and claim protect, also can make a lot of form, these all belong within protection of the present invention.
