The invention discloses a method for installing a bridge crane in a closed space, which comprises the following steps of: 1, paving a pair of rails on the ground, and disconnecting the corresponding positions between the two rails; step 2, paving a first layer of sole timber on the ground between the disconnected parts between the two rails, and erecting a jack; 3, the walking cart is hoisted until wheels on the two sides fall on the disconnected position of the two rails, and then the hoisting trolley is hoisted to the walking cart; 4, the walking cart is jacked repeatedly through a jack, sole timbers are laid during jacking every time, and jacking operation is completed until the walking cart ascends to the position that the distance between wheels and the ground is larger than the height of a track; 5, supplementing and laying rails at the disconnected position between the two rails to obtain a complete rail; and 6, the jack jacks the walking cart, and then the sole timber is drawn away until the walking cart falls until the wheels fall on the track which is laid in a supplementary mode. The high-altitude operation time is short, and the safety is high.
本发明公开了一种封闭空间内桥式起重机安装方法,包括以下步骤:步骤1、在地面上铺设一对轨道,使两轨道中间对应位置断开;步骤2、在两轨道中间断开处之间地面上铺设第一层垫木并支设千斤顶;步骤3、将行走大车吊至两侧的车轮落在两轨道断开处,然后将起重小车吊至行走大车上;步骤4、通过千斤顶多次顶升行走大车,每次顶升时铺设垫木,直至行走大车上升至车轮距离地面的高度大于轨道高度,完成顶升作业;步骤5、在两轨道中间断开处补充铺设轨道得到完整的轨道;步骤6、令千斤顶顶升行走大车,然后抽走垫木,直至行走大车下落至车轮落在补充铺设的轨道上。本发明高空作业时间短,安全性高。
