The invention relates to a lifting device for diversion lines of a
power transmission line tension
tower, and belongs to the technical field of maintenance of
power equipment. The lifting device for the diversion lines of the
power transmission line tension
tower comprises a U-shaped ring and rotation devices, wherein the U-shaped ring is provided with a downward opening, the rotation devices are arranged at bottom ends of two sides of the U-shaped ring, hooks are fixedly connected with the rotation devices and rotate with the rotation devices around an axial line, each rotation device is a thrust
ball bearing and bearing seat, the thrust
ball bearing comprises a seat ring and a shaft ring, hooks are fixedly connected with the shaft rings, and the hooks, the U-shaped ring and the rotation devices are all made of insulation materials. The two hooks are arranged at bottom ends of the
inverted U-shaped ring, more balanced stress on a steel
pipe framework can be ensured, and the steel
pipe framework is easier to lift. The hooks and the rotation devices are fixed, and the hooks can randomly rotate and are convenient to hook the steel
pipe framework from a gap between diversion lines; and the lifting device is lifted by fastening a screw rod, the lifting device is simple in structure, and a labor saving effect can be achieved.
