The invention provides a device and a method for transporting duct pieces in a well under special working conditions, the device comprises a duct piece bearing frame and a lifting appliance, the duct piece bearing frame comprises a bottom plate, a plurality of supporting seats are arranged on the bottom plate, the upper surfaces of the supporting seats are attached to the lower surfaces of the duct pieces, raised stop blocks are further arranged on the two sides of the bottom plate, and the inner side surfaces of the stop blocks are close to the side surfaces of the duct pieces; the lower ends of the lifting rods are connected with the bottom plate, and the upper surface of the lifting appliance is connected with a sling of the crane through at least four steel cables. After the device is pulled to a platform through a duct piece transport vehicle and a pull rope, the pressure and risk borne by workers during underground operation can be reduced by using the duct piece bearing frame and the lifting appliance, and damage caused by instability of the duct piece in the transport process is avoided.

    本发明提供一种特殊工况下管片下井运输装置及运输方法,包括管片承载架和吊具组成,管片承载架包括底板,底板上设有多个支撑座,支撑座上表面与管片下表面贴合,底板两侧还设有凸起的挡块,挡块内侧面靠近管片侧面;吊具上设有多个吊杆,吊杆下端与底板连接,吊具上表面通过至少四根钢索与吊机的吊索连接。采用管片运输车、拉绳将该装置拉至平台处后,使用管片承载架和吊具,可以减少工人在井下作业时承受的压力和风险,避免因运输过程中管片的不稳定而造成伤害。
