Abstract
The invention discloses a hoisting construction method of a dual crane rail large-tonnage device, comprising the steps of: on three-dimensional wall surfaces entering floors drawn up to enter by the device, reserving door openings, paving steel rails, processing tower crane bases, putting tower cranes and collocated facilities in place, transporting needed hoisting devices to the site, tying and hooking the devices, trying hanging, hoisting, withdrawing the tower cranes and the like. The invention has the advantages of high safety coefficient, fast hoisting speed, low cost and advanced technologies.
Description
Technical field
The present invention relates to a kind of large-tonnage equipment hoisting construction method.
Background technology
In recent years, fast development along with industrial economy, land resources day is becoming tight, industrial premises is more and more heavier to multilayer, high-rise development, its mechanical body weight, its large-tonnage equipment is installed and has been brought a technical difficult problem, say in some sense, because large-tonnage mechanical equipment hoisting difficulty is large, hoists to extend to industrial factory building and brought restraining factors.
Summary of the invention
The object of the present invention is to provide a kind of safety factor high, lifting speed is fast, the double-rail large-tonnage equipment hoisting construction method that cost is low.
Technical solution of the present invention is:
A kind of double-rail large-tonnage equipment hoisting construction method is characterized in that: comprise the following steps:
(1) draft the three-dimensional metope of the floor that enters at equipment, reserve door opening, door opening adds 20% above coefficient by equipment external form plan area to be reserved, after reserving at portal mouth week embedding subsides plank or rubber pad;
(2) steel rail laying, rail will be drafted laying floor face road and clear up before laying, and choice structure stake and Equipment Foundations are established the traction anchor point on the steel rail laying route of drafting, and track adopts channel steel type; After channel-section steel is laid, place mat solid drawn pipe rolling bar, the thick sheeting caps of place mat 15mm on the solid drawn pipe rolling bar is finished rail place mat operation again;
(3) process in the tower crane base, adds the weight of equipment of hanging according to tower machine own wt and add tower machine own wt and 50% of the weight of equipment sum of hanging again, and calculates the substantially required bearing capacity of tower crane, carries out the base according to the required bearing capacity in base and process; The base processing mode adopts cement concrete base, composite earth base or steel plate base;
(4) crane machine and allocation of facility are in place, and be according to configuration requirement that two tower machines and configuration are comprehensively in place, in place after, carry out sky machine running tentative, operation freely, test passes is stand-by;
(5) when weather fine, wind-force＜4 grade are transported to the scene with required hanging device;
(6) equipment colligation fishhook, mechanical equipment adopt three-dimensional positive lifting in when lifting, when equipment when falling to encircle, carry out colligation with steel rope, the pulling force of its steel rope is 2 times of necessary 〉=equipment gravity after tested; Use the intersecting parallels colligation during colligation, and at four criss-cross places, the amount of establishing suspension ring;
(7) jointly carry out the equipment examination with two tower machines and hang, repeatedly try to hang more than 2 times, examination is hung and highly is 3m;
(8) after hanging successfully by twice examination, lift to the flooring equipment place that enters, when hanging device enters floor, a tower machine pine hook, change by the bottle gouard moved by hands that arranges in the floor of place and equipment is drawn in floor and be placed on the preprepared track sheeting caps, then another tower machine also breaks off relations;
(9) equipment after winching to flooring moves away equipment, in order to provide the lifting place to carry out the lifting of next device;
(10) the tower machine is withdrawn from, and after equipment hoisting is finished, the tower machine is connect hook and flexible position instrument is dismantled comprehensively, cleans vanning, and complete machine is withdrawn from, and to former tower machine base residue, greasy dirt is cleared up, and restores to the original state.
Safety factor of the present invention is high, and lifting speed is fast, and cost is low, advanced technology.
The invention will be further described below in conjunction with embodiment.
The specific embodiment
A kind of double-rail large-tonnage equipment hoisting construction method comprises the following steps:
(1) draft the three-dimensional metope of the floor that enters at equipment, reserve door opening, door opening adds 20% above coefficient by equipment external form plan area to be reserved, after reserving at portal mouth week embedding subsides plank or rubber pad;
(2) steel rail laying, rail will be drafted laying floor face road and clear up before laying, and choice structure stake and Equipment Foundations are established the traction anchor point on the steel rail laying route of drafting, and track adopts channel steel type; After channel-section steel is laid, place mat solid drawn pipe rolling bar, the thick sheeting caps of place mat 15mm on the solid drawn pipe rolling bar is finished rail place mat operation again;
(3) process in the tower crane base, adds the weight of equipment of hanging according to tower machine own wt and add tower machine own wt and 50% of the weight of equipment sum of hanging again, and calculates the substantially required bearing capacity of tower crane, carries out the base according to the required bearing capacity in base and process; The base processing mode adopts cement concrete base, composite earth base or steel plate base;
(4) crane machine and allocation of facility are in place, and be according to configuration requirement that two tower machines and configuration are comprehensively in place, in place after, carry out sky machine running tentative, operation freely, test passes is stand-by;
(5) when weather fine, wind-force＜4 grade are transported to the scene with required hanging device;
(6) equipment colligation fishhook, mechanical equipment adopt three-dimensional positive lifting in when lifting, when equipment when falling to encircle, carry out colligation with steel rope, the pulling force of its steel rope is 2 times of necessary 〉=equipment gravity after tested; Use the intersecting parallels colligation during colligation, and at four criss-cross places, the amount of establishing suspension ring;
(7) jointly carry out the equipment examination with two tower machines and hang, repeatedly try to hang more than 2 times, examination is hung and highly is 3m;
(8) after hanging successfully by twice examination, lift to the flooring equipment place that enters, when hanging device enters floor, a tower machine pine hook, change by the bottle gouard moved by hands that arranges in the floor of place and equipment is drawn in floor and be placed on the preprepared track sheeting caps, then another tower machine also breaks off relations;
