Abstract
The utility model relates to a novel upward curve moving formwork which comprises a pier I, a pier II, a pier III, a box girder, a girder and a nose girder. The box girder and the girder are placed on the pier I and the pier II, and the nose girder is mounted at the front end of the girder. The pier I, the pier II and the pier III are arranged in a curve mode, the front end of the nose girder is supported on the pier III through a front supporting leg, and the front end and the rear end of the box girder are provided with a middle trolley and a rear trolley respectively. One end of the girder is mounted on the rear trolley through a transverse moving device, the other end of the girder is mounted on the middle trolley, and the middle trolley is provided with a rotating device. Thus, when the girder drives the nose girder to enable the rear end of the girder to move in the transverse direction through the transverse moving device mounted on the rear trolley in the longitudinal moving process, due to the fact that the rotating device is arranged on the middle trolley below the front end of the girder, when the girder is transversely moved, the mounting position of the middle trolley and the girder is used as a supporting point, the rear end of the girder deflects relative to the box girder, and therefore the girder can make curve movement along the circular arc which is formed by the pier I, the pier II and the pier III through the way of gradual deflecting when the girder moves longitudinally.
Description
Technical field
The utility model relates to mechanical field, is specifically related to a kind of bridge construction machinery.
Background technology
Mobile formwork bridge fabrication machine is employed in the Construction of continuous beam of road bridge, railway bridge abroad widely, is comparatively advanced job practices.Domestic the beginning used on speedway, special line for passenger trains.Due to the little impact of under-clearance, so need to select upstroke movable framework.But sometimes exist the case beam that the situation of horizontal curve is arranged, the upstriker mould bases via hole more complicated that this moment is common is therefore need the mobile formwork curve movement.
Summary of the invention
The utility model provides a kind of novel up curve movement mould bases in order to overcome the deficiency of above technology
The technical scheme that its technical problem that overcomes the utility model adopts is:
This upstriker curve movement mould bases, comprise bridge pier I, bridge pier II, bridge pier III, be positioned at case beam, girder on bridge pier I and bridge pier II, be installed on the bridge of the nose of girder front end, described bridge pier I, bridge pier II and the curved layout of bridge pier III, the front end of the described bridge of the nose is supported on the bridge pier III by front leg strut, before and after on described case beam, two ends are separately installed with middle dolly and rear dolly, described girder one end is installed on rear dolly by Traverse Displacement Unit, its other end is installed on middle dolly, is provided with whirligig on described middle dolly.
Above-mentioned Traverse Displacement Unit comprises traversing beam, the sideslip oil cylinder that is installed on rear dolly top, described traversing beam becomes cross-shaped with the case beam, described girder is movably installed on traversing beam, and an end of described sideslip oil cylinder is fixed on girder, and its other end is fixed on traversing beam.
Above-mentioned whirligig comprises bottom girder and rotating beam and the bearing pin that is arranged in the dolly bottom, is provided with circular hole on described bottom girder and rotating beam, and the size of described circular hole size and bearing pin is complementary, and described rotating beam rotatably is installed on bottom girder by bearing pin.
the beneficial effects of the utility model are: due to the bridge pier I, bridge pier II and bridge pier III are circular curve and arrange, therefore when driving the bridge of the nose, girder make the rear end of girder along transverse shifting by the Traverse Displacement Unit on dolly after being installed in the vertical shift process, because the middle dolly below the girder front end is provided with whirligig, therefore girder when traversing to produce deflection with the installation site of middle dolly as the relative case beam in fulcrum its rear end, thereby girder can make it along the bridge pier I by deflection progressively when vertical shift, the circular curve motion that bridge pier II and bridge pier III consist of, realize that finally girder moves on bridge pier II and bridge pier III from bridge pier I 1 and bridge pier II.

The specific embodiment
Be described further below in conjunction with accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, accompanying drawing 4, accompanying drawing 5,6 pairs of the utility model of accompanying drawing.
as accompanying drawing 1, shown in accompanying drawing 2, this upstriker curve movement mould bases, comprise bridge pier I 1, bridge pier II 2, bridge pier III 3, be positioned at the case beam 4 on bridge pier I 1 and bridge pier II 2, girder 6, be installed on the bridge of the nose 8 of girder 6 front ends, described bridge pier I 1, bridge pier II 2 and the curved layout of bridge pier III 3, the front end of the described bridge of the nose 8 is supported on bridge pier III 3 by front leg strut 9, before and after on described case beam 4, two ends are separately installed with middle dolly 7 and rear dolly 5, described girder 6 one ends are installed on rear dolly 5 by Traverse Displacement Unit, its other end is installed on middle dolly 7, be provided with whirligig on described middle dolly 7.due to bridge pier I 1, bridge pier II 2 and bridge pier III 3 are circular curve and arrange, therefore when driving the bridge of the nose 8, girder 6 make the rear end of girder 6 along transverse shifting by the Traverse Displacement Unit on dolly after being installed on 5 in the vertical shift process, because the middle dolly 7 below girder 6 front ends is provided with whirligig, therefore girder 6 when traversing to produce deflections with the installation site of middle dolly 7 as the relative case beam 4 in fulcrum its rear end, thereby girder 6 can make it along bridge pier I 1 by deflection progressively when vertical shift, the circular curve motion that bridge pier II 2 and bridge pier III 3 consist of, realize that finally girder 6 moves on bridge pier II 2 and bridge pier III 3 from bridge pier I 1 and bridge pier II 2.
