The invention discloses a self-locking bolt structure capable of being conveniently connected with a standard knot of a tower crane. The self-locking bolt structure comprises a slotted bareheaded screw, a nut in threaded connection with the top end of the slotted bareheaded screw, a fixing sleeve matched with the bottom end of the slotted bareheaded screw in an inserted mode, and a locking sliding block used for clamping the slotted bareheaded screw to the fixing sleeve. The elastic ring is used for limiting the locking sliding block to the fixing sleeve; and the positioning pin is used for relatively fixing the fixing sleeve and a bolt sleeve of a standard knot. The self-locking bolt structure has the advantages of being simple in structure, convenient to install and high in reliability, the number of constructors can be reduced, and the installation efficiency is improved.

    本发明公开了一种便于连接塔式起重机标准节的自锁螺栓结构,该自锁螺栓结构包括开槽光头螺杆、与开槽光头螺杆顶端螺纹连接的螺母、与开槽光头螺杆底端插接配合的固定套、用于将开槽光头螺杆卡接于固定套的锁定滑块、以及用于将锁定滑块限位于固定套的弹性环以及将固定套与标准节的螺栓套相对固定的定位销。上述自锁螺栓结构具有结构简单、安装方便、可靠性高的特点,并且能够减少施工人数、提高安装效率。
