Abstract

The invention provides a small-curve-radius steel box girder bridge erecting machine and an erecting construction method. The bridge erecting machine comprises a bridge erecting machine main beam, a front supporting leg device arranged at the front end of the bridge erecting machine main beam, a rear supporting leg device arranged at the rear end of the bridge erecting machine main beam, a middlesupporting leg device arranged at the position, close to the rear end, of the bridge erecting machine main beam and a middle supporting leg transverse moving rail arranged in the transverse bridge direction, and the bottom of the middle supporting leg device is installed on the middle supporting leg transverse moving rail. And a front crown block 16 and a rear crown block 17 are arranged on the bridge girder erection machine main beam. When the middle supporting leg sliding block on the middle supporting leg transverse moving rail is moved; when the steel box girder is erected, the girder tailof the main girder of the bridge girder erection machine can move along with the main girder, the rotating angle of the bridge girder erection machine can be adjusted, the whole attitude of the bridge girder erection machine can be adjusted to the steel box girder erection attitude, the steel box girder erected by the bridge girder erection machine in the attitude is the set steel box girder attitude, and the method is suitable for erecting small-curve-radius steel box girders.

Description

technical field [0001] The invention belongs to the technical field of bridge engineering, and in particular relates to a steel box girder erecting machine with small curve radius and an erecting construction method. Background technique [0002] With the rapid development of my country's economy, the number of bridges is also increasing. In order to shorten the construction period of bridges, give full play to the characteristics of materials, and improve economic and social benefits, steel box girder bridges have gradually become one of the important forms of bridge structures. At the same time, due to the environmental complexity, functional diversity, and linear complexity of the steel box girder bridge construction, it has a great impact on the installation and construction of the steel box girder, especially to solve the problem of the steel box girder under the small curve radius. erection problem. [0003] For example, steel box girders are used for the 5th to 7th j...
