Abstract
The utility model discloses a transition support for a high speed rail box-bridge erecting machine, which comprises a front outer support, a rear outer support, a front inner support and a rear inner support. Each outer support is in a multiple cushion box type, a bridge erecting machine hosting pole (1), support leg columns (2) and cushion boxes (3) are arranged on the outer support, and each cushion box is 450mm in height. Each inner support is in an integrally lifting type and composed of a support pole 4 and pinhole columns 5, each pinhole column 5 is provided with eighteen pinholes in nine rows, and the pinholes have spacing in accordance with 1*295mm + 6*450mm + 1*280mm + 1*200mm, and are 120mm in aperture. When the transition support is used for lifting and lowering the bridge erecting machine, plugging and unplugging speed of pins is quick, labor is saved, structural rigidity is enhanced, stability is improved, and the bridge erecting machine is prevented from tilting. Rigidity of the outer supports is enhanced, and an operation space for removing the cushion boxes on a bridge deck is large, so that operation is easy and operation time is shortened.
Description
Technical field
The utility model relates to a kind of transition support of high ferro box beam bridge formation machine, belongs to bridge formation machine technology field.
Background technology
The transition support is made up of former and later two outer supports and former and later two inner supports are formed, and under the cooperation of Beam transportation vehicle, bridge formation machine height can be reduced by the transition support, bears the bridge formation machine by hand basket bowstring arch bridge and tunnel by the Beam transportation vehicle and the support of cutting to then.Existing transition support also is made up of former and later two outer supports with former and later two inner supports; Be supported for the multi-joint telescoping formula outward, its structural Rigidity Design deficiency, when lifting bridge formation machine, less stable.Inner support is that the more piece pad is box, the operating space is narrow and small, when reducing bridge formation machine height, removing when inner support is switched political loyalty seat wastes time and energy, because there is structure interval in more piece pad case, when cutting to, very big rocking can take place simultaneously when bearing the bridge formation machine, and the great dangerous situation that the bridge formation machine tilts once repeatedly appearred, can't guarantee safe in utilization.Can't bear nose girder and bridge formation machine simultaneously.
Summary of the invention
The technical problems to be solved in the utility model is, provide that a kind of easy to use, rigidity of structure is big, the high ferro box beam bridge formation machine of good stability transition support, with overcome outer support stiffness deficiency, front and back inner support that prior art exists remove waste time and energy when switching political loyalty seat, cut to rock, dangerous, can not bear deficiencies such as nose girder and bridge formation machine simultaneously in addition.
The technical solution of the utility model: it comprises former and later two outer supports, former and later two inner supports; It is box to be supported for the more piece pad outward, and it has bridge formation machine lifting shoulder pole, supporting leg column and pad case, and the height of every joint pad case is 450mm.
Inner support is an integrally-lifting, is made up of support shoulder pole, pin-and-hole column at inner support, on each pin-and-hole column nine rows is arranged, totally ten eight pin-and-holes, and spacing is 1 * 295mm+6 * 450mm+1 * 280mm+1 * 200mm, its aperture is 120mm.
Compared with the prior art, the utility model inner support is an integrally-lifting, and when jacking and reduction bridge formation machine, by latch power transmission and the load in the pin-and-hole in the pin-and-hole column, it is fast to dial the sub-speed of latch, saves the labour.After the bridge formation machine dropped to the position, pin-and-hole column and crossbeam had been eliminated the component space of former inner support with pin and bolton, strengthened the rigidity of structure, have reduced rocking of bridge formation machine, have improved the stability of packing, and have prevented that the bridge formation machine from tilting.It is box to be supported for the more piece pad outward, and it is carried out rigidity strengthen, subtracting when getting the pad case, and operation on bridge floor, the space is big, and is easy to operate, shortened the activity duration, reduced labour intensity.
Description of drawings
Fig. 1 is based on external supporting structure figure of the present utility model.
Fig. 2 is an inner support structure chart of the present utility model.
The specific embodiment
Embodiment of the present utility model: it comprises former and later two outer supports, former and later two inner supports; It is box to be supported for the more piece pad outward, and it is made up of bridge formation machine lifting shoulder pole 1, supporting leg column 2 and pad case 3, and the height of every joint pad case is 450mm.
Inner support is an integrally-lifting, and it is made up of support shoulder pole 4, pin-and-hole column 5, on each pin-and-hole column 5 nine rows is arranged, totally ten eight pin-and-holes, and spacing is 1 * 295mm+6 * 450mm+1 * 280mm+1 * 200mm, its aperture is 120mm.
Reduce bridge formation machine height, pack state for transition from the state-transition of setting a roof beam in place, as shown in Figure 1, 2, fixedly bridge formation machine and the outer connection of supporting earlier, and bear bridge formation machine rearward weight.The support shoulder pole 4 of inner support and crane ' s major girder welding, as lifting power, jack-up bridge formation machine slightly makes to be supported for the state of not stressing outward, reduces highly 450mm of each pad case 3 of pad case 3(with the balanced oil cylinder group of Beam transportation vehicle), and fix with latch.By Beam transportation vehicle and inner support with bridge formation machine decline 450mm about, make outer support stressed, extract the latch of inner support pin-and-hole column 5 and support shoulder pole 4, Beam transportation vehicle jacking 450mm, again behind the mating holes, fix with latch,, make the relative Beam transportation vehicle of bridge formation machine reduce 450mm by this circulation, when the needs low level is crossed hand basket bowstring arch bridge and tunnel, utilize the balanced oil cylinder group of Beam transportation vehicle to drop to lowest order, guarantee overall height, realize transition by hand basket bowstring arch bridge and tunnel less than 9700mm.By after, the balanced oil cylinder group of utilizing Beam transportation vehicle equally the jacking of bridge formation machine to the height of setting a roof beam in place.
