The invention provides an electrical equipment hoisting and threading operation rod convenient for height adjustment. The operation rod comprises a lifting plate, a supporting plate, a lifting operation rod, an expansion mechanism, a supporting wheel frame and a hoisting rope; the two side edges of the lifting plate are slidably connected with two telescopic cylinders correspondingly; four telescopic elastic wheels are fixedly connected to the bottom surface of the supporting plate; a shaft of the lower end of the left side of the expansion mechanism is rotatably connected to the upper surface of the supporting plate through a bearing, a shaft of the upper end of the left side of the expansion mechanism is rotatably connected to the lower surface of the lifting plate through a bearing, and sliding blocks on the upper side and the lower side of the expansion mechanism are slidably connected into an upper sliding rail of the lifting plate and a lower sliding rail of the supporting plate correspondingly; and the left end of the lifting operation rod is rotatably connected into a fixing block hole of the expansion mechanism. Therefore, the equipment realizes the conversion of a clamping force by utilizing the gravity of the equipment, so that the stress of a concrete tower drum is more balanced when the concrete tower drum is lifted, and the probability that the concrete tower drum is damaged due to stress concentration easily caused by uneven stress during lifting is reduced.
本发明提供一种方便调节高度的电力设备吊装穿线操作杆,包括升降板,支撑板,升降操作杆,扩张机构,支撑轮架,起重绳索;所述升降板的两侧边分别滑动连接有两处伸缩筒;所述支撑板的底面固定连接有四处伸缩弹性轮;所述扩张机构的左侧下端轴通过轴承转动连接在支撑板上表面,且扩张机构的左侧上端轴通过轴承转动连接在升降板的下表面上,并且扩张机构的上下两侧的滑块分别滑动连接在升降板的上滑轨和支撑板的下滑轨内;所述升降操作杆的左端转动连接在扩张机构的固定块孔内;可以看出,此设备利用自身重力实现夹紧力的转换,使混凝土塔筒在进行起重时受压更加平衡,减小了起重时受力不均匀容易出现应力集中而损坏的几率。
