The invention discloses a synchronous jacking type gantry crane device which solves the problem that an existing TBM (Tunnel Boring Machine) cannot be provided with a gantry crane or the hoisting cost is too high in limited space environments such as mine roadways, underground engineering, low or gantry crane-free plants and the like. The synchronous jacking type gantry crane device comprises a split cushion box track, a walking trolley and an electric drive type door-shaped main frame, the electric drive type door-shaped main frame comprises two sets of electric lifting executing mechanisms and a bridge type double beam connected to the two sets of electric lifting executing mechanisms, a crown block lifting mechanism capable of moving along the bridge type double beam is arranged on the bridge type double beam, and the electric lifting executing mechanisms move along the cushion box track through the walking trolley. The modular design is adopted, compared with a traditional gantry crane, the modular gantry crane is simple in structure, transfer operation can be rapidly completed in a narrow small underground roadway or a small space, meanwhile, rapid assembly and disassembly can be achieved, an auxiliary crane is not needed in the process, and efficiency is greatly improved; and the synchronous jacking function ensures the stability and accuracy of jacking.
本发明公开了一种同步顶升式门吊装置,解决现有TBM(全断面隧道掘进机)在矿山巷道、地下工程、低矮或无门吊厂房等有限空间环境下,面临无法安装门吊或者吊装成本过高的难题。本发明同步顶升式门吊装置,包括分体垫箱轨道、行走小车、电驱式式门形主架;电驱式门形主架包括两组电动升降执行机构和连接在两组电动升降执行机构上的桥式双梁,桥式双梁上设有能沿桥式双梁移动的天车起吊机构,电动升降执行机构通过行走小车沿垫箱轨道移动。本发明采用模块化设计,相较于传统的门吊结构简单,能够在狭窄的地下小巷道或小空间内迅速完成转运作业,同时能够实现快速安拆,过程无需借助辅助吊车,效率大幅提高;其同步顶升功能保证了顶升的稳定与准确。
