A highway bridge erecting machine suitable for erecting a girder with an ultra-small curve radius

Abstract

The utility model discloses a highway bridging machine suitable for super-small curve radius beam erecting, when erecting different span beam pieces, the bridging machine girder machine arm assembly state is different, through reducing the bridging machine girder machine arm length to adapt to super-small curve, through zero column, one column, no.2 column can rotate oppositely on the plane curve of girder machine arm to adapt to curve radius, one column has two kinds of installation mode of inside and outside to adapt to super-small curve radius, through no.2 column horizontal moving track and the anchoring of already erected beam surface provide the lateral stability of bridging machine to ensure that the beam body to be erected moves in position, to this end, the beam piece erection of conventional greater than 300m curve radius and less than 300m super-small curve radius is realized, the beam piece is directly erected in position by the bridging machine under super-small curve radius, compared with cast-in-place construction, crane construction and setting up auxiliary buttress, the construction cost is greatly reduced, and the equipment is widely applicable.
