Special construction process for mounting stacker-reclaimer gantry
The invention discloses a special construction process for mounting a stacker-reclaimer gantry. The process comprises the following steps that first, the crane position is set, four auto cranes are adopted for hoisting, two 350t auto cranes serve as the main cranes, the hoisting points of the two 350t auto cranes are arranged at the centers of two arms at the top of the gantry up and down, the hoisting point of a 130t auto crane is arranged at the position, close to a central column, of the gantry, and the hoisting point of another 80t auto crane is arranged on the walking mechanism side of the gantry; second, a walking mechanism is hoisted; third, a gantry hoisting test is carried out, two cranes of the gantry are slowly hoisted by 0.5 m under the hoisting command at first, at the moment,the head of the gantry has already lifted, the 130t auto crane at the point B and the 80t auto crane at the point C are slightly lifted up to leave the ground to wait for 10 minutes, and the stressing conditions of all stressing points are checked; fourth, gantry rotating is conducted; and fifth, gantry lifting is made in place. According to the method, the structural design is reasonable, the gantry can be effectively mounted under the condition that a steel ball net rack is mounted, time is saved, and positioning and adjusting are facilitated.
本发明公开了一种堆取料机门架安装专项施工工艺，包括如下步骤：步骤一、吊车站位设置，吊装采用四台汽车吊进行吊装，其中两台350t汽车吊为主吊车，其吊点设在门架顶部两条臂中心处一上一下，一台130t汽车吊的吊点设在门架靠近中心柱处，另一台80t汽车吊的吊点设置于门架行走机构侧，步骤二、行走机构吊装，步骤三、门架起吊试验，首先门架的两台吊车在起重指挥下，缓缓起吊，抬起0.5米，此时门架头部已经抬起，B点的130t汽车吊，C点的80t汽车吊稍微提起离开地面，等待10分钟，检查各受力点的受力情况，步骤四、门架转体，步骤五、门架起升就位，本发明结构设计合理，在钢球网架安装完成状态下，实现对门架的有效安装，节省时间，也便于定位调整。
