Abstract
The utility model relates to a bridging machine, comprising a main girder (1), a lifting trolley (3) positioned above the main girder, a front, a middle and a rear supporting legs (7) (8) (9) with running gears and arranged under the main girder and a transition idler roller (4). The inner of the abdominal cavity of the main beam (1) is provided with a nose girder (5) with a front supporting leg (6) and a nose girder draw gear (2) for driving the nose girder (5) to do front and rear displacement. The utility model has the advantages of short main girder, low cost and convenience for installation and disassembly, is suitable for building bending (oblique) bridges, and provides facility for lateral displacement at the time of erecting bridges.
Description
The utility model relates to a kind of bridge formation machine that is used to set up concrete prefabricated beam class bridge.
Existing bridge formation machine mainly comprises girder, is positioned at the lifting dolly of girder top, and be arranged on the girder below have running gear before, during and after supporting leg.The course of work of its unloaded reach is as follows: at first pack up front leg strut (this moment, the girder front end was in full cantilever position), in the utilization, the rear support leg running gear drives the reach of whole bridge formation machine, till moving on the bent cap of striding bridge pier before front leg strut can be placed on, can carry out setting up of next Kong Liang afterwards.Because being the whole displacement by girder, the zero load of above-mentioned bridge formation machine reach realizes, at the long enough (girder length generally is about 2.2 times of bridge span) that just certainly will make that the girder of bridge formation machine is made, to satisfy the needs of displacement balance, in the increase that also just must cause the whole cost of bridge formation machine, also strengthened the workload of installation, transportation, dismounting simultaneously.
The purpose of this utility model provides a kind of structure more scientific and reasonable bridge formation machine with regard to being to overcome above-mentioned weak point of the prior art.
The purpose of this utility model can take following measure to realize:
The purpose of this utility model bridge formation machine comprises girder, be positioned at the lifting dolly of girder top, and be arranged on girder below have running gear before, during and after supporting leg and transition carrying roller, the intraperitoneal of girder be provided with one have before a nose girder that moves back, and be used to drive the nose girder draw-gear that nose girder is done forward and backward displacement.
Girder short (be about bridge span 1.4 times), cost are low except that having compared to existing technology for the utility model, the advantage of installation, transportation, convenient disassembly, also have and be applicable to and build curved (tiltedly) bridge, and the facilitate advantage of condition of the lateral displacement during for bridge formation.
Accompanying drawing is a front view of the present utility model.
The utility model is done with detailed description below with reference to embodiment (accompanying drawing):
Bridge formation machine of the present utility model comprises girder (1), what be positioned at girder top is used to lift by crane concrete prefabricated beam lifting dolly (3), and be arranged on girder below have running gear before, during and after supporting leg (7) (8) (9) and transition carrying roller (4), be provided with one at the intraperitoneal of girder (1) and move back the nose girder (5) of (6) before having, and be used to drive nose girder (5) is done forward and backward displacement along the guiding mechanism of girder (1) intraperitoneal setting nose girder draw-gear (2).
Bridge formation machine unloaded operation process of the present utility model is as follows:
During bridge formation machine zero load reach, at first driving nose girder by the nose girder draw-gear moves forward with cantilever position, after moving on the bent cap of striding bridge pier before front leg strut can be placed on, with nose girder supporting leg and the bent cap anchoring of before striding on the bridge pier, rely on support and the guide slide of nose girder afterwards as girder, in girder, under the driving of rear support leg running gear, move forward, move to the work of to set a roof beam in place after (surpassing the bent cap center line) on the bent cap of striding bridge pier before the girder front leg strut can be placed on.
Claims (1)
1, a kind of bridge formation machine, it comprises girder (1), be positioned at the lifting dolly (3) of girder top, and be arranged on girder below have running gear before, during and after supporting leg (7) (8) (9) and transition carrying roller (4), it is characterized in that: be provided with one at the intraperitoneal of girder (1) and move back the nose girder (5) of (6) before having, and be used to drive the nose girder draw-gear (2) that nose girder (5) is done forward and backward displacement.
