Description
Technical field
The invention belongs to heater hoisting technology fields, and in particular to a kind of standing heater turn setting lifting engineering method.
Background technique
Extra-supercritical unit engineering in general includes more vertical high pressure heaters, is arranged side by side in Turbine Engine Foundation platform one
Side.Vertical high pressure heater height is generally 12-15m, weight 180t-260t, has the characteristics that height is big, heavy；And
And it is used to support the formal foundation elevation of high-pressure heater generally in 3m or so, how by vertical high pressure heater safety, steady
Ground is lifted on the basis of formal, is the technical problem of this field.
In the prior art, power station high-pressure heater is all horizontal installation, and lifting mode is the bridge using steam turbine building setting
Formula crane is directly lifted this method in place by bridge crane and is not suitable for vertical high pressure heater.Vertical high pressure heater needs
Vertical lifting, it is also necessary to solve the problems such as tank body is turned over, erect, rotating.
Traditional Lao Xinge hydraulic lifting method needs in the sky to turn over tank body uprightly, during air turning is upright,
The rate of load condensate of bridge crane is constant, needs to pay close attention to the stability of lifting process, if unbalance stress will cause instantaneously mistake
It carries；And during high-pressure heater turns over upright in the sky, wirerope is to equipment appurtenance (such as instrument tube socket, pipe fitting
Deng) and equipment paint exist damage risk, affect process quality control；And there is also costs for Singh's hydraulic lifting method
Disadvantage high, the activity duration is long.
In addition, the maximum spacing of steam turbine building bridge crane main hook and operating layer platform generally only has 13m or so, Wu Faman
Sufficient high-pressure heater vertical length lifting, that is to say, that high-pressure heater, which must lift by crane, moves to the other space in formal basis in place
It turned over, erect again.However in the engineering method of the prior art, it not can be realized in the limited situation in equipment factory building space
It safely and efficiently completes large-scale vertical heater and lifts problem in place.
Summary of the invention
In view of the above technical problems, the present invention provides a kind of vertical high pressure heater turn setting lifting engineering method, vertical height
Pressing heater to turn over upright process is to carry out on the ground, is turned over when standing upright, and main stress point is temporary concrete basis,
The rate of load condensate of bridge crane substantially reduces, and construction quality controllability is high compared with conventional construction method；And turn over upright mistake
Journey carries out on the ground, the damage risk that wirerope paints equipment appurtenance and equipment when reducing air turning；It solves
Large-scale vertical heater is safely and efficiently completed in the limited situation in equipment factory building space and lifts problem in place, while for from now on
The construction of same type units equipment hoisting provides Technical Reference.
The present invention is achieved by the following technical solutions:
A kind of vertical high pressure heater turn setting lifting engineering method, the high-pressure heater include tank body, are set to tank body
The top hanging scaffold at top, two high-pressure heater pedestals for being set to tank base opposite sides；The lifting engineering method includes:
According to high-pressure heater pedestal size and and spacing, pour on the ground temporary concrete basis；By high pressure plus
Hot device carries out angle adjustment on turning rolls, adjusts to two high-pressure heater pedestals and is located in same level, by high pressure plus
Hot device level is sling, and is then placed on by temporary concrete basis and is fixed temporarily support and forms two high-pressure heater pedestals
For being horizontally arranged the platform of high-pressure heater, correcting wedge is placed in advance on the basis of temporary concrete, with interim coagulation
Fulcrum of the earth foundation as high-pressure heater pedestal, lifting heater at the top of hanging scaffold carry out hoisting and overturning, turn over when standing upright with
Angle is gradually increased, and gradually stress, stress point gradually transit to horizontal component from the wedge-like portion of correcting wedge to correcting wedge, high
It presses heater to complete to erect, it is in place then to carry out vertical lifting again.
Further, the lifting engineering method specifically includes:
Temporary concrete foundation construction: the temporary concrete base as high-pressure heater pedestal fulcrum is poured on the ground
The size of plinth, temporary concrete basis is determined according to the size and spacing of the high-pressure heater pedestal；
Correcting wedge production: using sleeper make correcting wedge, correcting wedge include have key groove wedge-like portion and
Horizontal component；

Ensure normal；When checking two driving joint debuggings, main hook lifting velocity, the actuated small roadster speed of travel should keep synchronous, prevent hoisting process
It is middle because caused by asynchronous two vehicle-mounted lotuses be unevenly distributed, equipment deflection the problems such as, form security risk.
Heater is unloaded: as shown in figure 4, vertical high pressure heater is sling by level in transport vehicle disk, crossing steamer
Machine basic platform is placed on the roller carrier special；Preferably, it is driven a vehicle using two 145/32t and lifts the scheme of unloading, two
It drives a vehicle and vehicle, two driving main hook spacing 8.88m, two driving main hooks passes through connection pulling plate, pin shaft and 500t connecting traverse respectively and connect
For entirety.The wirerope of 500t suspension hook (self weight 15t) hanging 80 × 25m of a pair of Ф, hangs mode (8 strand) using pocket and is unloaded
Vehicle.
The adjustment of heater angle: being rotated the tank body of vertical high pressure heater using turning rolls, until tank base
Two high-pressure heater pedestals in same level, then high-pressure heater is sling and is placed on by the temporary concrete
The basic and described platform for being used to be horizontally arranged high-pressure heater for being fixed temporarily support composition；Specifically, tank base
Two high-pressure heater pedestals are respectively placed in two flat surfaces on the temporary concrete basis, and tank body is placed on described face
When hold-down support on, entire high-pressure heater is in horizontal positioned.
Heater, which turns over, to be erect: as seen in figs. 5-6, suspension centre being moved to the top hanging scaffold of top of the tank, main hook steps up
And two high-pressure heater pedestals, which are cooperated using temporary concrete basis as fulcrum, to be rotated, and high-pressure heater is slowly erect, with
It erects angle to be gradually increased, the gradually stress of the correcting wedge on the basis of temporary concrete, wedge-shaped part of the stress point from correcting wedge
Divide and gradually transit to horizontal component, entire high-pressure heater completes steady setting, at this time two high-pressure heater pedestals and wedge shape
The horizontal component of cushion block contacts；Preferably, it turns over before erectting, should check that bolt has fastened completion at high-pressure heater support, prevent
During only turning over, bolt looseness, local pressure excess load cause bolt fracture；When upright, high-pressure heater is supported on temporarily
In concrete foundation, high-pressure heater pedestal is contacted with the horizontal component of correcting wedge, ensure that upright process steadily carries out.
Heater is vertically in place: continuing after lifting by crane high-pressure heater to appropriate height, installation high-pressure heater sliding end rolling
Wheel, idler wheel continue to complete the vertical raising of high-pressure heater in place on the basis of being hung to formally after being installed.
In the present embodiment, when carrying out lifting high-pressure heater, lifting region periphery must set special messenger and guard, to prevent
It damages people, basis and equipment etc..High plus surface is coped in hoisting process takes necessary protection, in order to avoid to equipment in hoisting process
It causes to scratch and damage.
