The invention discloses a fast assembled and disassembled hard safety rail. A head end rail frame (1) is connected with a plurality of continuous connecting rail frames (2) to form the safety rail. An upper transverse rod (4) and a lower transverse rod (5) are installed between two stand columns (3) to form a frame, wherein the upper portion and the lower portion of one stand column are provided with an upper connecting sleeve (6) and a lower connecting sleeve (8) respectively to form the head end rail frame (1). An upper transverse rod (4) and a lower transverse rod (5) are transversely installed on one stand column (3) to form a half frame, wherein the upper transverse rod (4) is provided with an upper connector (7), the lower transverse rod (5) is provided with a lower connector (9), and the upper portion and the lower portion of the stand column (3) are provided with an upper connecting sleeve (6) and a lower connecting sleeve (8) respectively to form one continuous connecting rail frame (2). The fast assembled and disassembled hard safety rail is simple in structure and convenient to install, the rail frames are directly connected and can be dismantled only by using a tool, and safety is guaranteed in power construction.
Description
technical field [0001] The invention relates to an isolation device used for safety protection and area isolation in a construction site, in particular to an isolation device used in an electrical equipment construction site for entering a charged area by mistake, in particular to an installed hard safety fence. Background technique [0002] The State Grid Corporation of China's "Electrical Industry Safety Work Regulations" stipulates that safety fences and warning signs must be set up around adjacent live equipment for maintenance of substation equipment to prevent maintenance personnel from accidentally entering live intervals and accidentally touching live equipment. The national standard GBT17045-2008 "General Parts of Electric Shock Protection Devices and Equipment" stipulates that the safety fence should have sufficient mechanical strength, stability and durability, be firmly and safely fixed in its position, and can only be operated with keys or tools. tear down.
