Abstract
The utility model relates to a functionally detachable supporting leg structure for a bridge girder erection machine. The functionally detachable supporting leg structure for the bridge girder erection machine comprises supporting and hanging wheels, lifting vertical pillars, vertical pillar oil cylinders, a transverse motion mechanism and a cross beam, wherein the supporting and hanging wheels are independent components, bear a stressed component supporting the load and a functional component for walking of a supporting leg, and are connected with a support leg part through bolts. The lifting vertical pillars, the transverse motion mechanism and the cross beam are respectively designed to a symmetrical and detachable structure, and have the same functions and organization arrangement.
Description
Technical field
The utility model belongs to railway construction machine apparatus field, be specifically related to a kind of can functional split-type supporting leg.
Background technology
In nose girder, supporting leg is vitals of split type tunnel Bridge Erector, at present in tunnel Bridge Erector industry market, Bridge Erector carrying leg structure form has variation, but under all kinds of working conditions, mostly adopt monolithic functional structure form to realize construction working condition requirement, and when bearing heavy duty, supporting leg cross sectional dimensions requires larger, adopting existing structure form to realize this Bridge Erector supporting leg is lifted upper and lower bridge floor and is had inconvenience more, Bridge Erector carry out circuit first and last bridge beam set up operation time to construction, bring a large amount of back works, greatly reduce efficiency of construction.
Utility model content
The purpose of this utility model is for the problems referred to above, provide a kind of for Bridge Erector can functional split-type supporting leg.Described can functional split-type leg structure, carrying supporting leg can be carried out to symmetry half-and-half splits, thereby significantly reduced supporting leg area of section size, by equipment, carry crane gear supporting leg is lifted step by step from nose girder below and makes it bridge floor top through neutral gear in the middle of nose girder, be fixed on plane on nose girder and set position.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of can functional split-type leg structure, described structure comprises holder change gear, lifting column, transverse-moving mechanism, crossbeam, wherein holding in the palm change gear is an individual components, bear the stressed member of support bearing and the functional part of supporting leg traveling, by bolt, partly connect with supporting leg, and lifting column, transverse-moving mechanism, crossbeam are all designed to the symmetrical detachable structure that makes, there is identical function and arrangement of mechanism, so that Bridge Erector, when carrying out first and last bridge Beams Erection Construction, is realized quickly and easily supporting leg and is lifted upper and lower bridge floor.
When splitting supporting leg, holder change gear is separated with supporting leg column, hangs on nose girder lower railway plate, moves together with nose girder.
Of the present utility modelly can functional split-type supporting leg carrying supporting leg be designed to symmetrical detachable structure form, when normal erecting beam construction operation, the symmetrical two parts of this supporting leg are coupled to each other by bolt, form overall structure and bear construction load.During conducting transmission line first and last bridge erection, this supporting leg is interfered bridge erection because of meeting and is constructed, need the upper bridge floor of lifting, the easy fractionation at this moment this supporting leg being divided into two, lifts respectively through completing the upper bridge floor operation of supporting leg lifting to nose girder upper surface on neutral gear in the middle of nose girder.
In nose girder, supporting leg is a most important carrying supporting leg in nose girder supporting leg, and when nose girder bears beam sheet load, Beam transportation vehicle load with self load, nose girder is relative with supporting leg static, is static overload; When taking out nose girder, nose girder supporting leg only bears nose girder deadweight, and nose girder and supporting leg relative motion, be dynamic underloading; These two kinds of operating modes are transferred to construction load on supporting leg by different supporting way, bear all load, and the conversion of these two kinds of bearing modes are realized by the supporting leg column combining by custom-designed a set of switching mechanism on supporting leg.
Beneficial effect
(1) this supporting leg adopts symmetrical structure layout, is arranged symmetrically with telescopic oil cylinder, transverse-moving mechanism, unbalance loading phenomenon in the time of can preventing mechanism kinematic;
(2) this supporting leg adopts detachable structure design, has solved well the problem of the upper bridge floor of supporting leg lifting, can not need other auxiliary crane gear, directly by equipment, carries jack machinism by the upper bridge floor of supporting leg lifting.Solved supporting leg sectional dimension large and cannot be through the problem of nose girder neutral gear.
(3) required aid equipment while having reduced the construction of Bridge Erector first and last hole, has reduced workload and labour intensity, has significantly improved efficiency of construction.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
A kind of can functional split-type leg structure, described structure comprises holder change gear, lifting column, transverse-moving mechanism, crossbeam, wherein holding in the palm change gear is an individual components, bear the stressed member of support bearing and the functional part of supporting leg traveling, by bolt, partly connect with supporting leg, and lifting column, transverse-moving mechanism, crossbeam are all designed to the symmetrical detachable structure that makes, there is identical function and arrangement of mechanism, so that Bridge Erector, when carrying out first and last bridge Beams Erection Construction, is realized quickly and easily supporting leg and is lifted upper and lower bridge floor.
When splitting supporting leg, holder change gear is separated with supporting leg column, hangs on nose girder lower railway plate, moves together with nose girder.
Of the present utility modelly can functional split-type supporting leg carrying supporting leg be designed to symmetrical detachable structure form, when normal erecting beam construction operation, the symmetrical two parts of this supporting leg are coupled to each other by bolt, form overall structure and bear construction load.During conducting transmission line first and last bridge erection, this supporting leg is interfered bridge erection because of meeting and is constructed, need the upper bridge floor of lifting, the easy fractionation at this moment this supporting leg being divided into two, lifts respectively through completing the upper bridge floor operation of supporting leg lifting to nose girder upper surface on neutral gear in the middle of nose girder.
In nose girder, supporting leg is a most important carrying supporting leg in nose girder supporting leg, and when nose girder bears beam sheet load, Beam transportation vehicle load with self load, nose girder is relative with supporting leg static, is static overload; When taking out nose girder, nose girder supporting leg only bears nose girder deadweight, and nose girder and supporting leg relative motion, be dynamic underloading; These two kinds of operating modes are transferred to construction load on supporting leg by different supporting way, bear all load, and the conversion of these two kinds of bearing modes are realized by the supporting leg column combining by custom-designed a set of switching mechanism on supporting leg.
Finally it should be noted that: obviously, above-described embodiment is only for the utility model example is clearly described, and the not restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all embodiments.And the apparent variation of being amplified out thus or change are still among protection domain of the present utility model.
