Portable protection device for high-altitude power maintenance
The invention provides a portable protection device for high-altitude power maintenance. The portable protection device for the high-altitude power maintenance comprises a ladder stand, and two clamping mechanisms are symmetrically arranged at the upper end of the ladder stand. According to the portable protection device for the high-altitude power maintenance, the two clamping mechanisms are arranged on the upper part of the ladder stand, two winding mechanisms rotate clockwise through handles on one-way gears, the lower ends of two steel wire ropes are wound around the circumferential facesof the inner sides of the two winding mechanisms correspondingly, therefore the upper ends of the two steel wire ropes pull the two clamping mechanisms linearly in the directions away from each othercorrespondingly, and then the upper part of the ladder stand is erected on a cylindrical telegraph pole, pull columns on two first limiting slide blocks are clamped on buckles, so that the one-way gear loses the limiting effect, then the two clamping mechanisms are clamped and fixed on the cylindrical telegraph pole under the action of first springs, and the upper part of the ladder stand is not easy to swing, and therefore, the safety of the ladder stand in use is improved.
本发明提供一种用于高空电力维护的便携式防护装置，包括:爬梯，所述爬梯上端呈对称状设有两个夹紧机构。本发明通过将爬梯上部设有两个夹紧机构，将两个缠绕机构通过单向齿轮上的把手均进行顺时针转动，使两根钢丝绳下端分别缠绕在两个缠绕机构内侧周面上，从而使两根钢丝绳上端分别将两个夹紧机构向相背方向直线拉动，然后将爬梯上部架设到圆柱形电线杆上，然后再将两个第一限位滑块上的拉柱卡接到卡扣上，使单向齿轮失去限位作用，从而使两个夹紧机构在第一弹簧的作用下夹持固定到圆柱形电线杆上，从而使爬梯上部不易发生摆动现象，进而提高了爬梯在使用时的安全性。
