Underground foundation pit deslagging and supporting gantry crane device

地铁基坑出渣和支护门吊装置

Abstract

An underground foundation pit deslagging and supporting gantry crane device comprises a main beam, a crane carriage, gantry supporting legs, a scrapper delivery device, a retractable supporting storage table, bottom connecting beams and an assistant lifting device, wherein the crane carriage is arranged on the main beam and can longitudinally move along the main beam; the two gantry supporting legs are respectively arranged on the two sides of the main beam; the bottom connecting beams are arranged between the gantry supporting legs on the two sides; the scrapper delivery device is fixedly connected with the bottom connecting beams on the deslagging side of the main beam; the two ends of the retractable supporting storage table are respectively connected with the bottom connecting beams on the two sides of the main beam; the assistant lifting device is fixedly connected with one side of the main beam. In the foundation pit supporting process, the concept of 'storing three and lifting one' can be realized through storage of steel supports, and the efficiency is higher; the deslagging productivity is high, and field restriction can be avoided; the conventional operating manner of digging the foundation pit layer by layer and section by section and finishing supporting of each section on limited time is changed, and synchronous conducting of foundation pit digging and foundation pit supporting is realized.
一种地铁基坑出渣和支护门吊装置,包括主梁、起重小车、门架支腿、刮板机输送装置、可伸缩支撑存台、底部连接梁和辅助吊装置,所述起重小车设置于主梁上且能沿主梁纵向移动,所述主梁的两侧分别设有两个门架支腿,且两侧的门架支腿之间设有底架连接梁;所述刮板机输送装置固结于主梁的出渣一侧的底架连接梁上,所述可伸缩支撑存台的两端分别滑动连接在主梁两侧的底架连接梁上,所述辅助吊装置固结于主梁的一侧;本实用新型在基坑支护过程中,通过存放钢支撑实现“存三吊一”,效率更高;且出渣作业效率高,不受场地限制;改变了传统基坑分层、分小段开挖并限时完成每小段支撑的作业方式,实现基坑挖掘和基坑支护同步进行。
