The round tenon standard knot structure of the tower crane comprises a plurality of stand column standard knots and reinforcing connecting plates arranged among the stand column standard knots, round tenon positioning rods are installed on the upper surfaces of the stand column standard knots, and concave holes capable of being clamped with the round tenon positioning rods are formed in the lower ends of the stand column standard knots. A limiting rod is arranged outside the round tenon positioning rod in a penetrating mode, a locking rod is arranged outside the limiting rod in a penetrating mode, a positioning sleeve is installed on the outer side of the stand column standard knot, the bottom end of the locking rod penetrates through the lower end of the positioning sleeve, and a locking nut is in threaded connection with the position, below the positioning sleeve, outside the locking rod. And a reinforcing mechanism is mounted on the upper surface of the reinforcing connecting plate. The round tenon positioning rod is embedded into the concave hole, meanwhile, the limiting rod penetrates through the limiting hole, and the tail end of the locking rod penetrates through the fixing hole and is locked with the interior of the positioning sleeve through the locking nut, so that the installation stability of the multiple stand column standard knots can be guaranteed.
本发明公开了一种塔机的圆榫标准节结构,包括多个立柱标准节以及设置在多个立柱标准节之间的加固连接板,所述立柱标准节的上表面安装有圆榫定位杆,下端开设有能与圆榫定位杆相互卡合的凹孔,圆榫定位杆的外部贯穿设置有限位杆,限位杆的外部贯穿设置有锁杆,立柱标准节的外侧安装有定位套筒,锁杆的底端贯穿定位套筒的下端,且锁杆的外部在定位套筒的下方螺纹连接有锁紧螺母;所述加固连接板的上表面安装有加固机构。本发明通过圆榫定位杆嵌入到凹孔的内部,同时使限位杆贯穿限位孔,并通过锁杆的末端贯穿固定孔与定位套筒内部用锁紧螺母锁紧,可保证多个立柱标准节之间的安装稳定性。
