Righting method of back-twist tower crane
The invention discloses a righting method of a back-twist tower crane. The righting method includes the following steps that S1, the back-twist tower is transported and lay on an installation site; S2, hoisting points are selected on the two ends of the back-twist tower correspondingly; S3, a main crane and a first auxiliary crane are connected to the hoisting point at the top of the back-twist tower, and a second auxiliary crane is connected to the hoisting point at the bottom of the back-twist tower; S4, the main crane, the first auxiliary crane and the second auxiliary crane work, and the back-twist tower is hoisted in a horizontal state to a predetermined height; S5, the main crane and the first auxiliary crane continue to raise, and the second auxiliary crane descends and lays a rod to enable the back-twist tower to rotate to a vertical state; and S6, the main crane puts the vertical back-twist tower on an installation position of the installation site. The back-twist tower is layon the installation site as a whole, and then the back-twist tower is integrally righted by the cranes; and compared with a vertical section construction, the operation is simple, the operation is safe, the high-altitude operation is reduced, and the construction risks and construction cost can be reduced.
本发明公开了一种退扭塔吊机扶正方法，包括以下步骤：S1、将退扭塔运送并卧放在安装现场；S2、在退扭塔的两端上分别选取吊点；S3、将主吊机和第一辅助吊机连接退扭塔顶部上的吊点，将第二辅助吊机连接退扭塔底部上的吊点；S4、主吊机、第一辅助吊机和第二辅助吊机工作，将退扭塔以水平状态吊起到预定高度；S5、主吊机和第一辅助吊机继续起高，第二辅助吊机下降并趴杆，使退扭塔旋转至垂直状态；S6、主吊机将垂直状态的退扭塔放置在安装现场的安装位置上。本发明将退扭塔整体卧放在安装现场，再通过吊机将退扭塔整体扶正；相对于立式分段建造，作业简单、操作安全、减少高空作业，可以降低施工风险和施工成本。
