A kind of assembly method of bridge erecting machine

Abstract

The invention discloses an assembling method of a bridge erecting machine. The assembling method of the bridge erecting machine comprises the following steps that S1, a bridge erecting machine body is assembled on the ground; S2, the bridge erecting machine body is integrally lifted to a first set height, and the structural stability of the bridge erecting machine body is inspected; S3, the bridge erecting machine body is sequentially lifted to a second set height, a third set height and a fourth set height, and then a back supporting leg, a middle supporting leg and a front supporting leg are sequentially installed on the bridge erecting machine body correspondingly; S4, a supporting frame is arranged below the back supporting leg and the middle supporting leg, the bridge erecting machine body is descended, and then the back supporting leg and the middle supporting leg are made to fall onto the supporting frame; S5, the bridge erecting machine is tested. By the adoption of the assembling method of the bridge erecting machine, the construction efficiency is high, the construction quality is easy to guarantee, a site is wide, multi-operation-plane parallel construction can be achieved, and the total duration of a project can be controlled beneficially; and meanwhile, the aerial work amount is reduced to the minimum, and the safety is improved.

Description

technical field [0001] The invention relates to the technical field of bridge erecting machines, in particular to an assembly method of bridge erecting machines. Background technique [0002] In the prior art, the bridge erecting machine is generally processed in sections in the factory, and needs to be pre-assembled and tested before leaving the factory. The conventional pre-assembly scheme is: install from bottom to top. Due to the heavy installation workload of the upper main truss, the proportion of high-altitude operations in the end accounts for 80% of the entire installation work, and high-altitude operations require the erection of scaffolds of the same height as a whole and use The truck crane cooperates with the operation, which has a large risk factor and high installation cost. Contents of the invention [0003] The present invention mainly solves the technical problems existing in the prior art, thereby providing a bridge erecting machine assembly method with...
