Construction device and construction process for mounting precast beam slab on bridge girder erection machine
The construction device comprises a main beam, two portal frames are fixedly connected to the main beam, a first moving wheel set is installed at the bottom of one portal frame, a second moving wheel set is installed at the bottom of the other portal frame, hoisting mechanisms are installed on the two sides of the main beam, and the main beam is fixedly connected with the main beam. And a precast beam plate is hooked at the bottom of the hoisting mechanism. The prefabricated beam plate hoisting device has the advantages that the anti-skid lines prevent the prefabricated beam plate from moving front and back, the bridge-shaped protection arms cover part of the prefabricated beam plate and jointly act with the anti-skid lines to prevent the prefabricated beam plate from shaking left and right in the hoisting and moving process, namely, the prefabricated beam plate is prevented from shaking when wind power is too large, and swinging of the prefabricated beam plate is prevented; the stability of the precast beam plate in the hoisting and moving process is further ensured; the prefabricated beam plate can be prevented from swinging front and back or left and right, waste of previous work caused by stop of installation work during gust is prevented, waste of manpower and material resources is prevented, and it is guaranteed that bridge erection work is conducted on schedule.
本发明公开了架桥机安装预制梁板施工装置及施工工艺，包括主梁，所述主梁上固定连接有两组龙门架，其中一组所述龙门架的底部安装有第一移动轮组，另一组所述龙门架的底部安装有第二移动轮组，所述主梁的两侧安装有起吊机构，所述起吊机构的底部钩有预制梁板。本发明的优点在于：防滑纹防止预制梁板前后位移，桥形护臂覆盖一部分预制梁板，与防滑纹共同作用防止预制梁板在吊装移动过程中左右晃动，即防止风力过大时使预制梁板晃动，防止预制梁板摇摆，进一步保证了预制梁板在吊装移动过程中的稳定性；能够防止预制梁板前后或左右摇摆晃动，防止在阵风时因停止安装工作导致前序工作的浪费，防止浪费人力物力，保证桥梁架设工作的如期进行。
