The invention discloses a lifting device and a lifting method for an integral box culvert in a conventional tunnel, and solves the problems that the integral box culvert is difficult to lift and low in efficiency when the clearance in a trailer of a shield tunneling machine for construction of the conventional tunnel (6m < = X < = 10m) is insufficient in the prior art. The hoisting device for the integral box culvert in the conventional tunnel comprises a moving frame capable of moving relative to a trailer, and the moving frame is provided with a hoist crane used for hoisting an open-close type clamping jaw; the opening and closing type clamping jaw comprises a clamping jaw body and a rotary driving mechanism connected with the hoist crane, and the clamping jaw body is movably arranged on the rotary driving mechanism and is opened and closed through an opening and closing driving piece. And when the box culvert is hoisted, the opening and closing type clamping jaws are matched with an access hole formed in the whole box culvert. According to the integral box culvert hoisting device, the opening and closing driving piece can control unfolding and stretching of the clamping jaw structure to achieve grabbing and releasing of the integral box culvert piece, and rapid hoisting of the integral box culvert is achieved. The integral box culvert hoisting device is compact in structure, has no special requirement for clearance in a shield tunneling machine trailer, and can meet the assembling function requirement of integral box culvert pieces of a conventional tunnel (X is larger than or equal to 6m and smaller than or equal to 10m).
本发明公开了一种用于常规隧洞中整体箱涵的吊运装置及吊运方法,解决了现有技术中常规隧道(6m≤X≤10m)施工盾构机拖车内净空不足时,整体箱涵吊运困难,效率低的问题。本发明用于常规隧洞中整体箱涵的吊运装置,包括能相对拖车移动的移动架,移动架上设有用于起吊开合式卡爪的起重葫芦;所述开合式卡爪包括卡爪和与起重葫芦相连接的旋转驱动机构,所述卡爪活动设置在旋转驱动机构上且通过开合驱动件进行开合动作;吊运箱涵时,开合式卡爪与设置在整体箱涵上的检修孔相配合。本发明的整体箱涵吊运装置中,开合驱动件可以控制卡爪结构的展开与伸缩来实现对整体箱涵件的抓取与释放,实现整体箱涵的快速吊运。本发明的整体箱涵吊运装置结构紧凑,且对盾构机拖车内净空无特殊要求,能够满足常规隧道(6m≤X≤10m)整体箱涵件拼装功能要求。
