Upper-layer electric shock prevention device for erecting lines on same tower

The invention belongs to the technical field of electric shock protection, and particularly relates to an upper-layer electric shock prevention device for erecting lines on the same tower. The devicecomprises a fixing hoop or a fixing strap detachably fixed to an electric pole body, the bottom end of a supporting rod is fixed to the fixing hoop or the fixing strap, and the top end of the supporting rod extends upwards and is fixedly connected with a supporting face; the supporting face is in a horizontal protection face shape, and the inner end, relatively close to the electric pole, of the supporting face forms a fixed end relative to the supporting rod. According to the invention, dynamic operation conditions of the maintenance operation of a power system can be satisfied without performing power failure operation on an upper-layer line of a same-pole erected line, and the safety of the maintenance operation of the power system can also be effectively ensured. 本发明属于触电防护技术领域，具体涉及一种同杆架设线路用上层防触电装置。本发明包括可拆卸的固定于
