Detachable double-splicing type large crawler crane underground back-jacking supporting structure
The invention discloses a detachable double-spliced type large crawler crane underground back-jacking supporting structure which comprises a double-spliced steel column, a column bottom plate, a jack, a column top connecting assembly, a transfer beam, a roadbed box, a side plate and an anti-torsion reinforcing assembly, the double-spliced steel column comprises a first H-shaped steel column and a second H-shaped steel column, the first H-shaped steel column and the second H-shaped steel column are spliced and welded, and the first H-shaped steel column and the second H-shaped steel column are spliced and welded. The column bottom plate is located below the first H-shaped steel column and the second H-shaped steel column, when an underground back-jacking supporting structure is erected by a worker, the first H-shaped steel column and the second H-shaped steel column are spliced into a double-spliced steel column at the bottom of a beam borne by a crawler crane through stress checking calculation, a jack drives a jack jacking block to conduct fine adjustment on the double-spliced steel column, and then the double-spliced steel column is erected. L-shaped angle iron is welded to tightly plug a gap between the bottom end of the double-spliced steel column and the top of the column bottom plate, the double-spliced steel column and the column bottom plate are fixed, back-jacking is conducted in a walking area of the large crawler crane, and the effects that cost is reduced, efficiency is improved, environment protection and safety are achieved, correction precision is high, and mounting and dismounting are convenient are achieved.
本发明公开了一种可拆卸双拼式大型履带吊地下回顶支撑结构，包括双拼钢柱、柱底板、千斤顶、柱顶连接组件、转换梁、路基箱、侧板和抗扭加固组件，所述双拼钢柱包括第一H型钢柱和第二H型钢柱，所述第一H型钢柱与所述第二H型钢柱对拼焊接，所述柱底板位于所述第一H型钢柱和所述第二H型钢柱下方，工人搭设地下回顶支撑结构时，通过受力验算，在履带吊承载的梁底，将第一H型钢柱和第二H型钢柱拼接成双拼钢柱，千斤顶驱动千斤顶顶块对双拼钢柱进行微调，焊接L型角铁塞紧双拼钢柱底端与柱底板顶部的间隙，将双拼钢柱与柱底板之间进行固定，在大型履带吊行走区域进行回顶，达到降本增效、环保安全、矫正精度高、安装拆卸方便的效果。
