Abstract

The utility model discloses a single-girder bridge erecting machine which comprises a girder, girder transport vehicles, a traction trolley, a front landing leg, a rear landing leg, a lower guide beam, an electric block and a lifting mechanism, wherein the girder is formed by connecting four strips of H-type steel and steel plates, square steel tracks are arranged on the H-type steel at the lower end of the girder, the traction trolley is placed on the square steel tracks on the H-type steel at the lower end of the girder in a bottom-bearing suspension manner, the front landing leg comprises an upper landing leg and a lower landing leg, and the upper landing leg and the lower landing leg are movably connected through a pin shaft. In the single-girder bridge erecting machine, the girder adopts a connecting structure of the H-type steel and the steel plates, so that the single-girder bridge erecting machine has the advantages of small size, light deadweight and uniform and low wheel pressure, and is convenient to disassemble, assemble and maintain; with the adoption of the bottom-bearing suspension structure, the height of the bridge erecting machine can be reduced; and the upper landing leg and the lower landing leg of the front landing leg are movably connected through the pin shaft, so that the front landing leg and the rear landing leg of the whole bridge erecting machine can form three-point static balance, the girder is prevented from generating additional distortion, the bridge erecting machine is higher in safety performance, and full-span single-track box girders and full-span double-track box girders can be erected.

Description

Single girder bridge formation machine
Technical field
The utility model relates to a kind of single girder bridge formation machine.
Background technology
Along with the development of high-speed railway and highway construction, various types of Large Box beam bridge formation machines have appearred both at home and abroad.Common railway bridge erecting machine wheel load is big, quality heavy, the cost expense is high.The single-beam bridge formation machine of foreign latest is the structure of deck type, structure and complicated operation, and manufacture difficulty is big.
Summary of the invention
The purpose of the utility model just provides the light compactness of a kind of structure, from heavy and light, easy to operate, can set up single girder bridge formation machine two, the single line beam.
Single girder bridge formation machine of the utility model; Comprise girder, Beam transportation vehicle, trailer wagon, front leg strut, rear support leg, following nose girder, electric block and lifting mechanism; Girder is combined by four H shaped steel and steel plate, and the H shaped steel of girder lower end is provided with the square steel track, and trailer wagon adopts the lower support type suspention to be placed on the square steel track on the H shaped steel of girder lower end; Front leg strut comprises upper supporting leg and following supporting leg; Upper supporting leg is movably connected through bearing pin with following supporting leg, and rear support leg adopts O type supporting leg, and rear support leg connects with girder with high-strength bolt.
Single girder bridge formation machine of the utility model, girder adopt H shaped steel and armor Plate, make type little, from heavy and light, wheel load is even, wheel load is little, and dismounting is easy to maintenance; Owing to adopted the lower support type overhung construction, can reduce the height of bridge formation machine; The upper and lower supporting leg of front leg strut is through the bearing pin form that is movably connected; Make the forward and backward supporting leg of whole bridge formation machine constitute 3 static(al) equilibriums, avoid girder to produce additional distortion, security performance is higher; Whole hole single, double line case beam be can set up, high ferro or expressway construction are applicable to.
