Electric power system maintenance ladder convenient to store and labor-saving in use
The invention provides an electric power system maintenance ladder convenient to store and labor-saving in use, and relates to the technical field of electric power systems. The electric power systemmaintenance ladder comprises a ladder rod, wherein an air cavity is formed in the inner wall of the ladder rod; an air leakage hole is formed in the bottom of the air cavity; a spring I is fixedly connected to the inner wall of the air leakage hole; a safety block is fixedly connected to the outer side of the spring I; an air outlet hole is formed in the middle of the safety block; an air inlet hole is formed in the bottom of the air cavity; a plugging block is rotationally connected to the inner wall of the air inlet hole; and a spring II fixedly connected with the inner wall of the ladder rod is fixedly connected to the bottom of the plugging block. According to the electric power system maintenance ladder convenient to store and more labor-saving in use, a foot bar I and a foot bar II are matched for use, and the foot bar I and the foot bar II are rotationally connected, so that the foot bar I and the foot bar II can be folded, the width of the maintenance ladder is reduced, the effect of conveniently storing the maintenance ladder is achieved, the storage and carrying of the maintenance ladder are facilitated, and the labor intensity of maintenance personnel is reduced.
一种便于收纳且使用更加省力的电力系统用检修梯，涉及电力系统技术领域，包括梯杆，所述梯杆的内壁开设有气腔，气腔的底部开始有泄气孔，泄气孔的内壁固定连接有弹簧一，弹簧一的外侧固定连接有安全块，安全块的中部开设有出气孔，气腔的底部开始有进气孔，进气孔的内壁转动连接有堵块，堵块的底部固定连接有与梯杆的内壁固定连接的弹簧二。该便于收纳且使用更加省力的电力系统用检修梯，通过踏杆一与踏杆二的配合使用，由于踏杆一和踏杆二是转动连接，所以唐安一和踏杆二可以折叠，从而减小检修梯的宽度，从而达到了便于检修梯存放的效果，有利于检修梯的收纳以及搬运，降低了检修人员的劳动强度。
