The invention relates to a crawler-type lifting rack for tunnel variable cross-section contact channel construction and a construction method. The crawler-type lifting rack comprises a crawler-type moving device, a supporting structure, a lifting system, a hydraulic system and the like. The crawler-type moving device mainly comprises a crawler, a connecting device, a variable frequency motor, a supporting platform, rollers, steering wheels and the like. The rack can be simply moved in some long tunnels, so that the construction is convenient; the supporting structure mainly comprises an upper supporting column, a lower supporting column, a connecting beam, inclined struts and the like; and the lifting system comprises four 8-ton oil cylinders and a lifting platform, and the hydraulic system provides power for the lifting system. A working plane with the corresponding height can be provided for workers, the tunnel construction time is greatly shortened, and operation is more convenient.
本发明涉及隧道变截面联络通道施工用的履带式升降台架及施工方法,包括了履带式移动装置、支撑结构、升降系统以及液压系统等;其中履带移动装置主要包括履带、连接装置、变频电机、支撑平台、滚轮、转向轮等。在一些长大的隧道中可简易地移动台架,方便施工;支撑结构主要包括上、下支撑柱、连接梁、斜撑等;升降系统包括4根8吨油缸与升降平台,液压系统为升降系统提供动力。本发明可为工作人员提供相应高度的工作平面,大大减少隧道施工时间,操作也更加便捷。
