The invention provides a lower limiting device of a steel wire rope, which is used for carrying out lower limiting detection on the steel wire rope wound on a winding drum, and comprises a bracket, a compression roller, spring devices and a travel switch, the bracket is arranged on two sides of the compression roller, the spring devices are arranged on two sides of the compression roller, and the travel switch is arranged on the compression roller. One end of the spring device is connected with the support, the other end of the spring device is connected with one end of the pressing roller, the support is connected with the two ends of the pressing roller through the spring device, and the travel switch is arranged on the support on one side of the pressing roller. The spring device is movably arranged between the travel switch and the two ends of the pressing roller and comprises a spring, when the spring is in a natural state, the pressing roller is attached to the winding drum, the travel switch works, and when the spring is compressed, one end of the travel switch is connected with the spring device to trigger the travel switch not to work. Inclined parts which are inclined upwards and inwards are arranged on the two sides of the compression roller, and the included angle between the inclined surface of each inclined part and the surface of the compression roller body is 15-20 degrees; in the descending process of the steel wire rope, the lower limiting position of the steel wire rope can be detected, the structure is simple, the detection accuracy is high, and the operation efficiency is improved.

    本发明提供了一种钢丝绳的下限位装置,用于对缠绕在卷筒上的钢丝绳进行下限位检测,包括支架,还包括压辊、弹簧装置、行程开关,所述支架安装在所述压辊的两侧,所述弹簧装置设置在所述压辊的两侧,所述弹簧装置的一端与所述支架连接,所述弹簧装置的另一端与所述压辊的一端连接,所述支架通过所述弹簧装置分别与所述压辊的两端连接,所述行程开关设置在所述压辊一侧的所述支架上,所述弹簧装置在行程开关与压辊两端之间活动设置,所述弹簧装置包括弹簧,弹簧处于自然状态时,压辊与卷筒相贴合,行程开关工作,弹簧被压缩时行程开关的一端与弹簧装置相连触发行程开关不工作,所述压辊的两侧设置有向上向内倾斜设置的倾斜部,所述倾斜部的倾斜面与所述压辊体表面之间的夹角为15°‑20°;在钢丝绳下降过程中,能够实现对钢丝绳下限位位置的检测,结构简单,且检测准确性高,提高作业效率。
