Bridge deck slab rotating system and mounting method
The invention provides a bridge deck slab rotating system and a mounting method. The system comprises a pulley block I, a rotary hook and winches; at least three winches are arranged, and the winchesare respectively a winch I, a winch II and a winch III; the winch I is connected with the pulley block I; the winch I is fixedly arranged on a bridge above the bridge surface of an approach bridge; the winch I is connected with the pulley block I through a steel wire rope; the pulley block I is connected with a lifting belt I in the bridge deck slab lifting center through a rotary lifting hook; and the winch II and the winch III are used for pulling the bridge deck slab to horizontally rotate. According to the invention, horizontal rotation, short-distance transverse movement and short-distance longitudinal movement of the bridge deck slab can be achieved; the lifting belt I is connected with the pulley block I through a rotary lifting hook and matches the winch II and the winch III to pull the bridge deck slab to realize horizontal rotation of the bridge deck slab; the lengths of a lifting belt II and a lifting belt III can be adjusted by winding and unwinding steel wire ropes of thewinch II and the winch III, and short-distance transverse movement of the bridge deck slab is achieved; and lifting and lowering of the bridge deck slab can be achieved by winding and unwinding the steel wire ropes of the winch I.
本发明提供了一种桥面板旋转系统及安装方法，包括滑车组一、旋转吊钩和卷扬机，卷扬机至少为三个，分别为卷扬机一、卷扬机二和卷扬机三，卷扬机一与滑车组一连接，卷扬机一固设在引桥桥面上方的桥梁上，卷扬机一通过钢丝绳与滑车组一连接，滑车组一通过旋转吊钩与桥面板吊装中心的吊带一连接，卷扬机二和卷扬机三用于牵引桥面板水平旋转。本发明可以实现桥面板的水平旋转以及短距离横移和纵移。吊带一通过旋转吊钩与滑车组一连接，配合卷扬机二和卷扬机三牵引桥面板实现桥面板水平旋转；通过收放卷扬机二和卷扬机三的钢丝绳可以调节吊带二、吊带三的长度，实现桥面板的短距离横向移动；通过收放卷扬机一的钢丝绳可以实现桥面板的提升和下放。
