The invention relates to a pole-mounted switch hoisting method and a hoisting support thereof.The hoisting support of a pole-mounted switch comprises a left support body installed on a left telegraph pole during use and a right support body installed on a right telegraph pole during use, and the left support body comprises a left hoop and a left cantilever capable of swinging back and forth relative to the left hoop; the swing axis of the left cantilever extends in the vertical direction. The right support comprises a right hoop and a right cantilever capable of swinging back and forth relative to the right hoop, the swinging axis of the right cantilever extends in the vertical direction, reversing pulleys allowing the pull rope to wind and reverse are rotationally assembled at the right end of the left cantilever and the left end of the right cantilever, and a cantilever reset elastic part is connected between the left cantilever and the right cantilever. According to the hoisting support and the pole-mounted switch hoisting method using the hoisting support, the pole-mounted switch can fall on the cross arm without pushing the pole-mounted switch at high altitude.
本发明涉及一种柱上开关起吊方法及其起吊支架,柱上开关的起吊支架包括使用时安装于左侧电线杆上的左侧支架和使用时安装于右侧电线杆上的右侧支架,左侧支架包括左侧抱箍和相对左侧抱箍能够往复摆动的左侧悬臂,左侧悬臂的摆动轴线沿上下方向延伸设置;右侧支架包括右侧抱箍和相对右侧抱箍能够往复摆动的右侧悬臂,右侧悬臂的摆动轴线沿上下方向延伸设置,左侧悬臂的右端和右侧悬臂的左端转动装配有供拉绳绕经换向的换向滑轮,左侧悬臂与右侧悬臂之间连接有悬臂复位弹性件。本提供了一种无需高空推动柱上开关,柱上开关既能够落于横担上的起吊支架及使用该起吊支架的柱上开关起吊方法。
