The invention discloses a ballasting underframe of an ultra-large type tower crane. The ballasting underframe comprises a tower body foundation section, two front side horizontal supporting beams, two rear side horizontal supporting beams, two long inclined supporting rods and two short inclined supporting rods, the length of the front side horizontal supporting beam is larger than that of the rear side horizontal supporting beam. The inner ends of the two front side horizontal supporting beams and the inner ends of the two rear side horizontal supporting beams are connected to the lower side of the tower body foundation section from four directions correspondingly, and the outer ends of the front side horizontal supporting beams and the outer ends of the rear side horizontal supporting beams are each provided with a hinge plate. The two front side horizontal supporting beams are arranged adjacently; the upper ends of the two long inclined support rods and the upper ends of the two short inclined support rods are respectively supported on the upper side of the tower body foundation section from the four directions; wherein the long inclined supporting rod adopts a truss structure, and the short inclined supporting rod adopts a sectional material tailor-welded structure; the truss structure facilitates on-site hoisting, meanwhile, the gravity center of the tower body foundation section can be more conveniently attached to the center of an air duct of wind power equipment through the long inclined supporting rods, and the maximum hoisting capacity effect of hoisting equipment can be more efficiently achieved.
本发明公开了一种超大型塔式起重机的压重底架,包括塔身基础节、两根前侧水平支撑梁、两根后侧水平支撑梁、两根长斜撑杆和两根短斜撑杆;前侧水平支撑梁的长度大于后侧水平支撑梁的长度;两根前侧水平支撑梁内端和两根后侧水平支撑梁内端分别从4个方向连接于塔身基础节的下侧,前侧水平支撑梁外端和后侧水平支撑梁外端均安装有铰接板;两根前侧水平支撑梁相邻布置;两根长斜撑杆上端和两根短斜撑杆上端分别从所述的4个方向支撑于塔身基础节的上侧;其中,长斜撑杆采用桁架结构,短斜撑杆采用型材拼焊结构;桁架结构方便现场吊装,同时较长的斜撑杆更方便塔身基础节重心贴近风电设备的风筒中心,可以更高效地发挥吊装设备最大起重量作用。
