Description

The stepless adjustable suspender of the eccentric case beam of large-tonnage

Technical field

The present invention relates to the technical field of bridge construction mechanical equipment, particularly relate to the stepless adjustable suspender of the eccentric case beam of a kind of large-tonnage.

Background technology

In bridge construction, particularly in highway bridge construction, double line box girder application is comparatively general, and in order to reduce the distance between centers of tracks between case beam, the flange plate of Pin beam near side of two casees beams all excises.Case beam is after excision flange plate, and center of gravity is not on horizontal lifting hole(eyelet) group switching centre line.According to traditional shoulder pole girder suspender, can to the lopsidedness not excising flange plate when lifting by crane, cause case torsion beam suspension and additionally produce additional bending moment to hanger rod for hanging appliance, not only affecting the lifting quality of case beam, also make case torsion beam suspension easily crack.Additional bending moment makes that suspension rod is stressed to be become by stretch bending from tension, easily affects safty hoisting operation, simultaneously when falling beam, because the case beam beam that tilts also to be not easy to fall on bridge pier puts in place.

Traditional method: increase counterweight in excision flange plate side, make the comprehensive gravity center of case beam and counterweight on horizontal lifting hole(eyelet) group switching centre line, the held stationary during lifting of guard box beam, but this increase counterweight way, cause the specified lifting amount of Bridge Erector to increase on the one hand, increase device fabrication cost; Often set up a Pin case beam on the other hand all need counterweight to hang on case beam and hang case beam, the hoisting aids equipment of increase, cause construction working quantitative change large, construction period lengthens, and construction cost increases.

At present, adjustable suspender is that fixed orifice adjusts apart from artificial mostly, utilizes and increases hanger rod component installation site, and by the installation of hanger rod component in different installation site, ensure that suspender movable pulley component center overlaps with case beam center of gravity, when ensureing to lift by crane, case Liangping is steady.This kind of way is simple and reliable for structure, because scantling of structure is restricted, can only adapt to eccentric distance to immobilize the handling of case beam, often hang a Pin case beam just needs, by accessory equipment, hanger rod component is moved on to other installation positions simultaneously, have impact on construction speed and cost of setting a roof beam in place.Also small part is had to adopt electronic adjustment and hydraulic pressure adjustment, the method is simple to operate, but need from horn, power power-line or hydraulic oil pipe to be guided on suspender, suspender oscilaltion, power power-line and oil pipe need to move thereupon, design is complicated, and cost is high, there is certain potential safety hazard; On suspender, be provided with propulsion source exactly, cost is high on the one hand for this way, affects suspender whole height on the other hand, reduces lifting range.

For this reason, designer of the present invention is because above-mentioned defect, and by concentrating on studies and designing, comprehensive experience and the achievement being engaged in related industry for a long time for many years, research and design goes out the stepless adjustable suspender of the eccentric case beam of a kind of large-tonnage, to overcome above-mentioned defect.
