Tube drawing bench for construction in underground narrow space and construction method
The invention discloses a tube drawing bench for construction in an underground narrow space and a construction method. The tube drawing bench comprises a traveling system and a tube drawing system, wherein the traveling system comprises a traveling chassis, a main arm, a lifting arm and a tube drawing winch, the tube drawing system comprises a tube twisting disc retracting and releasing structure, a tube twisting disc, a protective cylinder and a protective cylinder receiving disc, the protective cylinder receiving disc is connected with the main arm through a connecting rope, the tail end of the connecting rope is connected to the tube drawing winch, the protective cylinder is connected to the bottom end of the protective cylinder receiving disc, the tube twisting disc is connected to the tube twisting disc retracting and releasing structure, and the tube twisting disc retracting and releasing structure is arranged outside the traveling chassis. According to the tube drawing bench, the sectionally-arranged protective cylinders are matched with the main arm with the shortened length, so that the overall height of the tube drawing bench is reduced, the construction requirement for tube drawing in an underground narrow space is met, the tube twisting disc is arranged to repeatedly twist the protective cylinder in the pulling-out process to reduce the friction force during lifting, and the protective cylinder is stably and efficiently pulled out under the combined action of filing and upward pulling.
本发明公开了一种用于地下狭小空间内施工的拔管机及施工方法，包括行走系统和拔管系统，行走系统包括行走底盘、主臂、升降臂和拔管绞车；拔管系统系统包括搓管盘收放结构、搓管盘、护筒和护筒接盘，护筒接盘通过连接绳与主臂连接，连接绳的尾端连接在拔管绞车上，护筒连接在护筒接盘底端，搓管盘连接在搓管盘收放结构上，搓管盘收放结构设在行走底盘外端。本发明通过分段设置的护筒和缩短长度的主臂配合，降低了拔管机的整体高度，满足在地下狭小空间内进行拔管的施工要求；设置挫管盘在拔出过程中反复挫动护筒来减少提升时的摩擦力，并在挫动和上拔的共同作用，稳定且高效率的拔出护筒。
