Detailed description of the invention
With reference to accompanying drawing.
Self-propelled triangular truss hanging basket of the present utility model, is applicable to Long-span PC beam bridge, and it comprises load-bearing English truss, suspension, anchoring assembly, running gear, template assembly and working platform.
Load-bearing English truss comprises the truss upright-column 1 and truss longeron 2 that arrange in pairs, truss upright-column 1 adopts 2 25 i iron to be welded into lattice, truss longeron 2 adopts 2 32 i iron to be welded to form, connected by truss suspender belt 3 between truss upright-column 1 and truss longeron 2, truss suspender belt 3 adopts 2 20 channel-section steels to lean against and is welded to form, lateral connection 4 is provided with between paired truss upright-column 1, lateral connection 4 adopts channel-section steel cross weld to form, to bear beam wind load and to increase the lateral stability of Hanging Basket, load-bearing English truss also comprises front top rail 5, front lower transverse beam 6 and rear lower transverse beam 7, front top rail 5 mainly bears the effect of suspension rod concentrated force, curved to be subject to, therefore 2 40 i iron assembly weldings are adopted to become lattice rod member.
Suspension comprises front suspension rod 8, rear suspension bar 9, side form suspension rod 10, internal mold suspension rod 11 and bed die suspension rod 12, front suspension rod 8 is connected with front lower transverse beam 6 with truss longeron 2 through front top rail 5, rear lower transverse beam 7 is connected on the case beam 100 of having built by rear suspension bar 9, side form suspension rod 10 connects outside through front top rail 5 and hangs mould 101, internal mold suspension rod 11 connects interior mould bases 102 through front top rail 5, top rail 5 and bed die frame 103 before bed die suspension rod 12 connects respectively.
Running gear comprises sliding beam 13 and the sliding beam 14 of external mold skeleton, sliding beam 13 is fixedly connected on the case beam 100 of having built by anchor pole 15, truss longeron 2 is arranged on sliding beam 13 by front bearing 16 and rear support 17, front bearing 16 and rear support 17 are provided with thrustor, thrustor comprises lateral pushing device and longitudinal thrustor, lateral pushing device can promote English truss and move along sliding beam 13, longitudinal thrustor can promote English truss and move up and down, thus fine setting pouring position, the sliding beam 14 of external mold skeleton is connected on sliding beam 13 by sliding beam suspension rod 18, outside is hung mould 101 and is slidably mounted on the sliding beam 14 of external mold skeleton, when English truss moves along sliding beam 13, outside is hung mould 101 and can be moved along the sliding beam of external mold skeleton thereupon, realize triangular truss hanging basket voluntarily.
Lateral pushing device and longitudinal thrustor all adopt hydraulic top pushing device, by adjusting the pressure size of hydraulic pressure, can regulate the thrust of pushing tow, thus regulate pushing tow Distance geometry pushing tow height.
Girder length is called from truss upright-column 1 to the distance the suspension centre of truss suspender belt 3, the length of girder is determined by the cantilever section length of bridge, the maximum cantilever casting beam segment length of certain engineering jackshaft is 4m, before considering, suspension centre distance must treat casting beams section one segment distance simultaneously, this distance is taken as 0.15m, and rear anchor point distance waters beam section front end 0.5m, to ensure that the case beam base plate watering beam section has enough length to spread the rear anchor-hold being anchored at this place, to sum up, girder length 4+0.15+0.5=4.65m can be obtained.
The height of truss upright-column 1 directly has influence on the stressed of diagonal member and girder, affects the amount of deflection of suspension centre before Hanging Basket simultaneously.Column is too short, then the horizontal component of diagonal member at front suspension centre place is comparatively large and vertical force component is not enough, and horizontal component increases compared with the axle power of ambassador's girder, and it is then unfavorable to the amount of deflection of the front suspension rod of reduction that vertical force is not enough.But column also should not be too high, along with the increase of height, the slenderness ratio of column is larger, its stable problem will be more outstanding, certainly will will increase column cross section or take more measure to prevent its unstability, too increase length and the material usage of diagonal member simultaneously, according to the maximum cantilever casting beam segment length of bridge be 4m calculate, this bridge stem height gets 4.2m, and each rod member bearing distribution is reasonable, and main couple has larger rigidity.
