The device comprises a bottom plate, wheels are installed on the lower surface of the bottom plate, and a main support is installed on the upper surface of the bottom plate; the main support comprises two stand columns, a transverse column is installed at the top ends of the two stand columns, lifting lugs used for hanging a chain block are symmetrically installed on the lower surface of the transverse column, and when a shield machine is disassembled, under the condition that a screw conveyor cannot be pulled out and lifted at a time, a device formed by combining a flat car, I-shaped steel and the chain block is arranged in a tunnel. The hoisting process of an end well open space crane is replaced, the situation that under the condition that the screw conveyor is heavy and segments in a tunnel cannot meet the hoisting point setting requirement, the screw conveyor is pulled out of the tunnel through the convenient device pulled out of the screw conveyor, and then secondary hoisting out of the well is conducted is avoided, and the device is reasonable in design, easy to machine, convenient to operate and high in practicability. And the construction requirements of large shield screw conveyor dismantling and hoisting engineering under the condition of insufficient wellhead hoisting conditions are met, and the construction safety is ensured.
本发明公开了一种螺旋机拔除便捷装置,包括底板,所述底板的下表面安装有轮子,所述底板的上表面安装有主支架;所述主支架包括两个立柱,两个所述立柱的顶端安装有横柱,所述横柱的下表面对称安装有用于悬挂手拉葫芦的吊耳,盾构拆机时螺旋机不能一次拔除吊装情况下,在隧道内设置一种由平板车和工字钢与手拉葫芦进行组合的装置,代替端头井开阔空间吊机进行吊装的工艺,防止了因螺旋机重量大,隧道内管片不能满足吊点设置要求情况下,通过螺旋机拔出便捷装置,在隧道内将螺旋机拔出,然后再进行二次吊装出井,该装置设计合理,加工简单,操作方便,满足井口吊条件不足情况下大型盾构螺旋机拆除吊装工程施工需要,保证施工安全。
