Abstract
The invention discloses a mechanism for migrating a whole fixed tower crane, comprising a bracket girder, a vertical jack, a horizontal jack, a sleeper, and a steel plate slideway, wherein the bracket girder is used as a slideway base, the steel plate slideway that comprises two layers of steel plates and rolling shafts arranged between the two layers of steel plates is arranged on the slideway base, the vertical jack is arranged on the steel plate slideway, the horizontal jack leans against one side of the base through the sleeper for moving the tower crane. The invention further discloses a migrating method, comprising the following steps: firstly confirming a position after migration by the mechanism, then scooping off the earth of the original base position, the new base position, the slideway base and the path; constructing the slideway base, and installing the steel plate slideway on the slideway; arranging the horizontal jack and the vertical jack; loading the horizontal jack and the vertical jack to slide to the new base position; observing the verticality of the tower crane by using a theodolite, and adjusting by using the vertical jack, after meeting the requirement, replacing the vertical jack with a short steel section to remove the vertical jack; and filling up the base bottom by using fine aggregate concrete or grout, and then backfilling. According to the invention, the construction period caused by the migration is shortened, the cost is low, and the safety risk is greatly reduced.
Description
Technical field
The present invention relates to build Transport Machinery, especially relate to a kind of fixed type tower crane and underpin bulk migration mechanism and moving method.
Background technology
The fixed type tower crane is that present building industry is used maximum vertical transportation machineries, because a variety of causes need happen occasionally the thing of just moving to new location in the tower crane short range of operation.Method commonly used at present is exactly a newly-built basis, again organizes upright to new place fixed type tower crane dismounting back again.This method is tradition relatively, the technical maturity easy master.But the cost that produces is high, owing to need the dismounting crane, does the basis again in addition, needs the long period, influences the duration.
Summary of the invention
The purpose of this invention is to provide a kind of fixed type tower crane and underpin bulk migration mechanism and moving method,, reduce laid down cost, reduce security risk to save the duration.
For realizing above-mentioned purpose; The present invention provides a kind of fixed type tower crane whole transport mechanism, it is characterized in that: comprise underpining beam, vertical jack, level jack, sleeper, steel plate slideway, underpin beam and do the slideway basis; Be provided with above the slideway basis by accompanying the steel plate slideway that roller bearing constitutes between the two-layered steel plates; Be provided with vertical jack above the steel plate slideway, level jack leans against a side through sleeper, is used for moving tower crane.
A kind of fixed type tower crane whole moving method is characterized in that comprising the following steps:
1, the position after at first definite migration, the soil with former basic position, new base position, slideway basis and course digs out then;
2, construction slideway basis, and on the slideway basis, install the steel plate slideway;
3, layout level, vertical jack;
4, give level, vertical jack loading, slide into new base position;
5, with the squareness of theodolite observation tower crane, and with vertical jack adjustment, reach requirement after, replace vertical jack with lacking shaped steel, withdraw from vertical jack;
6, with pea gravel concreten or grouting material foundation bottom is filled, then back fill.
Advantage of the present invention is following:
1, in the process of whole tower crane migration, tower crane can both normal operation, does not influence normal construction, can shorten the duration that causes because of migration greatly.
2, the present invention does not need large-scale level and vertical transportation machinery in implementation process, does not need to do in addition the basis, and is with low cost, only is about 10% of conventional approach cost.
3, the present invention in force the overwhelming majority be Ground Operation, do not have aloft work, can reduce security risk greatly.
Description of drawings
Fig. 1 is a tower crane translation construction scheme drawing;
Fig. 2 is a tower crane translation front elevation view;
Fig. 3 is a tower crane translation side elevational view;
Fig. 4 is tower crane translated plane figure.
The specific embodiment
With reference to Fig. 1,2,3,4; Former tower crane 1; Underpin beam 2 and make slideway basis, vertical jack 3, level jack 4, steel plate 5, roller bearing 6, be provided with by accompanying the steel plate slideway that roller bearing constitutes between the two-layered steel plates above the slideway basis, be provided with vertical jack above the steel plate slideway; Level jack leans against a basic side through sleeper 7, is used for moving tower crane.
Translation construction concrete steps of the present invention are following:
1, at first confirm position after the migration, the soil with former basic position 8, new base position 9 and slideway basis and course digs out then;
2, construction is dragged and is changed beam 2 and do the slideway basis, and on the slideway basis, install steel plate 5 successively, steel plate slideway that roller bearing 6, steel plate 5 are combined into;
3, vertical jack is arranged, and begin basis 1 synchronous loading after full load, is begun to arrange sleeper 7 and level jack 4, and makes level jack 4 stressed;
4, through 4 pairs of basis 1 loadings of level jack,, constantly switch steel plate slideway and sleeper 7, slide into new base position up to tower crane along with the steady reach of tower crane;
5, after tower crane arrives new base position, with the squareness of theodolite observation tower crane, and with vertical jack 3 adjustment, reach requirement after, replace vertical jack with lacking shaped steel, withdraw from vertical jack;
6, with pea gravel concreten or grouting material foundation bottom is filled, then back fill.
The present invention has adopted two to underpin beam temporarily and do the slideway basis, the steel plate slideway of auxiliary two rollers, make fixed type tower crane pulsation-free move to new location from original position after, back fill after centering, the slip casting is accomplished whole transition processes.
Test Example 1
300,000 tons of/year alcohol fuel private station camp sites in the Jilin are because position MEASURING QUASI not during upright tower crane.Find to influence the revolution of other unit crane after using, approximately need about migration 3m.Because the duration is tight especially, on-the-spot place is narrower and small again, and large-scale crane, wooden handcart are difficult to get into, and that has therefore adopted method success of the present invention has moved 3.5m with tower crane, the equal normal operation of tower crane in whole process.
The tower crane of migration is the QTZ5011 type, high 25m, and deadweight adds counterweight 61 t.Underpinning is two 1000mmx600mm (height) reinforced concrete foundations; Slideway adopts two-layer 10mm steel plate folder Φ 25 mm round steel 200mm; Vertical 4 the 30t jacks of every side that adopt evenly arrange, level has adopted two 100t jack jack back two-layer sleeper.
Shoveling has been used a week with the foundation construction in early stage, and formal migration has used two day time to arrive estimating position, and a template has been poured into a mould the big flowing concrete of C30, backfill then behind the centering.Tower crane normally uses engineering later on to be finished.
Test Example 2
In logical steel camp site, it is back fill that half basic bottom is arranged when constructing because of tower crane, do not find at that time, and back tower crane run-off the straight, centering still tilts several times, therefore adopts the present invention with basic translation 2.5m.Method is identical with last example, and the not run-off the straight again of migration back tower crane normally uses engineering and finishes.
