The invention provides a rope lifting self-locking device, and relates to the technical field of rope self-locking devices. Comprising a shell, a self-locking disc used for preventing a rope from sliding and a locking mechanism enabling the self-locking disc to rotate in one direction, a cavity is formed in the shell, an opening is formed in the bottom of the shell, the self-locking disc is rotationally arranged in the cavity, a limiting groove is formed in the middle of the self-locking disc, and during use, one end of the rope penetrates through the opening to be wound in the limiting groove in the middle of the self-locking disc and then extends out of the opening; the locking mechanism comprises an elastic piece, a helical tooth gear disc and a sector gear pressing rod, the helical tooth gear disc is arranged on one side of the self-locking disc, the helical tooth gear disc and the self-locking disc coaxially and synchronously rotate, the elastic piece is arranged between the sector gear pressing rod and the shell, and the elastic piece drives the sector gear pressing rod to abut against the helical tooth gear disc and is used for enabling the helical tooth gear disc to rotate in one direction; a self-locking mechanism composed of the elastic piece, the helical gear disc and the sector gear pressing rod is adopted, the structure is simple, lifting of the rope can be effectively self-locked, and operation is easy and convenient.

    本发明提出了一种绳索升降自锁器,涉及绳索自锁装置技术领域。包括壳体、用于防止绳索滑动的自锁盘和使自锁盘单向转动的锁止机构,壳体内设有空腔,壳体的底部设有开口,自锁盘转动设于空腔内,自锁盘中部设有限位槽,使用时,绳索的一端穿过开口绕在自锁盘中部的限位槽内,然后从开口伸出;锁止机构包括弹性件、斜齿齿轮盘和扇形齿轮压杆,斜齿齿轮盘设于自锁盘一侧,且斜齿齿轮盘与自锁盘同轴且同步转动,弹性件设于扇形齿轮压杆与壳体之间,弹性件驱动扇形齿轮压杆抵压在斜齿齿轮盘上,用于使斜齿齿轮盘单向转动;本装置采用弹性件、斜齿齿轮盘和扇形齿轮压杆组成的自锁机构,结构简单,能有效对绳索的升降进行自锁,操作简单方便。
