Steel truss aqueduct erecting device and method for small-section asymmetric beam arch system
The invention discloses a device and method for erecting a steel truss aqueduct of a small-section asymmetric beam arch system. The device comprises a vehicle body, a lifting arm is installed on the vehicle body, a hoisting mechanism is installed at the end, away from the vehicle body, of the lifting arm, a clamping mechanism is installed at the bottom of the hoisting mechanism, a winding mechanism is installed on the vehicle body, and a lifting rope is installed between the winding mechanism and the hoisting mechanism. A limiting device and a three-way jack adjusting device are installed on a rigid support, divided small sections are hoisted and installed, matching pieces are arranged on the inner side of an empty box of an all-welding device, matching pieces, guide blocks and the like are arranged on the outer side of the empty box for connection, temporary fixing is conducted through a stacking plate after connection, component installation is completed, hoisting equipment is withdrawn out of a bridge floor, and welding personnel conduct welding in a symmetrical mode. The'rear end 'is firstly welded and fixed between the installed sections, so that the front end freely stretches out and draws back, and stress-free welding is achieved.
本发明公开了一种小节段非对称梁拱体系钢桁梁渡槽架设装置及方法，包括车体，车体上安装有吊臂，吊臂远离车体的一端安装有吊装机构，吊装机构的底部安装装夹机构，车体上安装有收卷机构，收卷机构与吊装结构间安装有吊绳。在刚性支架上安装好限位装置和三向千斤顶调节装置，起吊安装已划分好的小节段，全焊接装置空箱内侧设置匹配件，外侧设置匹配件、导向块等相连，连接后使用码板临时固定，完成构件安装，吊装设备撤出桥面，焊接人员采用对称方式焊接，先焊接“后端”，固定于已安装完成的节间，使前端自由伸缩，达到无应力焊接。
