Abstract
The invention relates to a lifting alignment in-place method for a boiler water storing tank. The method includes the following steps that actual in-place installation elevation and horizontal and longitudinal locating positions of the water storing tank are determined; the situation that a pre-storing bearing steel frame cross beam meets the requirement of pre-storing load of the water storing tank is determined, and temporary reinforcing measures are prepared well; measure beams are pre-stored and the arranging positions of measure beams on steel frame beams are determined, a pair of polytetrafluoroethylene plates are put as pads at each corner of the four contact points, and temporary reinforcement is carried out; during lifting and pre-storing, front, back, left and right parts of a lifted object are accurately adjusted, the elevation and locating errors are controlled to be within +/-2 mm, and the elevation is at most 50 mm and lower than the actual height; after a suspension pipe of the water storing tank is installed in place, alignment of the water storing tank starts, front-back and right-left adjustment is conducted by means of the polytetrafluoroethylene plates pressed by the four bearing points, and lifting and alignment are prepared after data are checked and free of errors; 50-ton jacks at the four corners slowly lift, and shim plates are added along with lifting; and the positions under the four corners are compacted through wedged pad iron after lifting to be in place, and locating pins of the jacks are locked. According to the lifting alignment in-place method for the boiler water storing tank, usage is convenient, and a large quantity of manpower and material resources can be saved.
Description
Technical field
The present invention relates to boiler water storage tank installing area, more particularly, to boiler water storage tank raising counterpart method in place.
Background technology
1050mw boiler water storage tank equipment in boiler factory weighs about (70-100) ton, and does not design the hanging system of equipment itself
System, the connecting pipe erecting by overhang burden installed mainly by the later stage, and this overweight equipment early stage prestores to adopt (650-1000) more
Ton crawler crane lifting prestores, and with the progress of engineering, after board roof hoisting finishes, large caterpillar is under normal circumstances also therewith
Withdraw, leave lower physical notches to subsequent installation counterpart, most scenes need to return assembly pulley with hoist engine and carry out secondary lifting.
This programme by interim for equipment deposit position finely positioning by drawing, and by conventional pre- location mode shoulder pole girder
Bottom arranges four 50 tons of hydraulic jack in advance, and the height that prestores slightly below designs height in place (20-50) mm, very heavy when prestoring
Top do not exert oneself, after top connecting pipe and erecting by overhang install, with jack jacking in place and implement weld.
Content of the invention
After the purpose of the present invention avoids board roof hoisting to finish, the physical notches problem that exists, and boiler water storage tank is provided
Raising counterpart method in place.
The present invention for achieving the above object, provides boiler water storage tank raising counterpart method in place, comprises the steps:
Confirm the actual installed height mark in place of water storage tank and horizontal, longitudinal register position；
The load-bearing steelframe crossbeam that confirms to prestore meets water storage tank and prestores loading, and carries out temperature pier measure, such as discontented full
Border is hung thing and is prestored loading, using interim measure material bracing reinforcement；
Prestore measure beam determine measure beam in truss-steel beam putting position, first pads at the every angle of four contact points and puts a pair poly- four
PVF plate, then carry out temperature pier；
Lifting will be hung thing when prestoring and all around be adjusted correctly, and absolute altitude and position error scope control, within ± 2mm, are marked
Height is not more than 50mm in actual height；
Water storage tank column pipe install in place after, water storage tank counterpart starts, using the polytetrafluoroethylene (PTFE) that press against under 4 points of load-bearing
Plate all around adjusts, and prepares raising counterpart after verification data is errorless；
The slow raising of 50 tons of corner jack, places parallels with raising；
Raising is padded with inclined sizing block below corner after putting in place, and jack locks alignment pin；
Complete counterpart and implement welding, inspection weld bond is qualified and determines interim measure off-the-line after the erecting by overhang stress of top.
Described measure beam is shoulder pole girder.
The invention has the beneficial effects as follows: boiler water storage tank raising counterpart of the present invention method in place, easy to use, permissible
Save substantial amounts of manpower and materials, such as, save the large-scale crane cost renting or even hundreds of thousands tens of thousands of no less than machine-team and
Large-scale crane need to use place；The scene of saving prepares two, two sets, more than 10 tons hoist engines of large pulley group, 10 single-sheaved blocks 14
Platform；Save extraordinary suspender lockset.
Specific embodiment
It is described in detail referring to the drawings below with reference to embodiments of the invention.
Boiler water storage tank raising counterpart method in place, comprises the steps:
Confirm the actual installed height mark in place of water storage tank and horizontal, longitudinal register position；
The load-bearing steelframe crossbeam that confirms to prestore meets water storage tank and prestores loading, and carries out temperature pier measure, such as discontented full
Border is hung thing and is prestored loading, using interim measure material bracing reinforcement；
Prestore measure beam determine measure beam in truss-steel beam putting position, first pads at the every angle of four contact points and puts a pair poly- four
PVF plate, then carry out temperature pier；
Lifting will be hung thing when prestoring and all around be adjusted correctly, and absolute altitude and position error scope control, within ± 2mm, are marked
Height is not more than 50mm in actual height；
Water storage tank column pipe install in place after, water storage tank counterpart starts, using the polytetrafluoroethylene (PTFE) that press against under 4 points of load-bearing
Plate all around adjusts, and prepares raising counterpart after verification data is errorless；
The slow raising of 50 tons of corner jack, places parallels with raising；
Raising is padded with inclined sizing block below corner after putting in place, and jack locks alignment pin；
Complete counterpart and implement welding, inspection weld bond is qualified and determines interim measure off-the-line after the erecting by overhang stress of top.
Described measure beam is shoulder pole girder.
The above is only the preferred embodiment of the present invention it is noted that ordinary skill people for the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
