Abstract

The invention discloses a method for reinforcing a bridge erecting machine. The method comprises the following steps that A, relative parameters such as the length and the diameter of each front supporting leg and the diameter of each pier column are measured; B, direct calculating or finite element calculating is conducted to determine a transverse reinforcing scheme and a longitudinal reinforcing scheme, wherein the transverse reinforcing scheme comprises the step that a plurality of supporting rods are connected between the two front supporting legs, and the longitudinal reinforcing scheme comprises the step that a plurality of supporting rods are connected between the pier columns and the front supporting legs; C, steel materials with corresponding section parameters and the corresponding lengths are selected; and D, the steel materials with the selected models and parameters in the step C are cut, and the front supporting legs and the pier columns are connected and reinforced according to the reinforcing schemes in the step B. By means of extra reinforcing measures, the weight of the whole machine can be reduced, and the manual labor of workers in the detaching process also can be reduced, most importantly, the problems of stability losing and fracturing of the front supporting legs the in the process of detaching and erecting a beam body is avoided, and the method can be widely applied to reinforcing of front supporting legs of various bridge erecting machines.

Description

technical field

[0001] The invention relates to a bridge erecting machine, in particular to a method for reinforcing the bridge erecting machine. Background technique

[0002] In the current bridge construction, due to the different construction environment and construction conditions, the outriggers of the bridge erecting machine also have different states of stress. However, due to the generality and theoretical nature of the structure of the bridge erecting machine, the design did not consider the different working conditions in the construction process on site and the instability of the structure due to stress.

[0003] When the bridge erecting machine is used to disassemble the beam body, in the process of laterally moving the crane, the span between the left and right legs of the front leg of the bridge erecting machine is relatively large, and the problem of lateral instability often occurs; when the crane is started , because the front outrigger of the bridge erecti...
