Description

Technical Field

[0001] The utility model relates to the technical field of insulating centipede ladders, in particular to a connecting support rod for insulating centipede ladders. Background Art

[0002] The traditional insulated centipede ladder is generally made of a single insulating tube as the main column, and an insulating ladder made of insulating plates made of strip steps arranged crosswise on the main column. It can be hung on a wire, a crossarm or fixed on the ground for use. When the insulated centipede ladder is used on the ground, it is generally first fixed on the ground by a steel plate, and then the insulated centipede ladder is placed on the steel plate for use. At the same time, it is necessary to fix four wind cables at the top and in the middle of the centipede ladder to achieve the purpose of stabilizing the centipede ladder. The current use method of the insulated centipede ladder is usually not stable enough when in use, especially in windy weather, the insulated centipede ladder is prone to shaking, which can easily cause the staff to fall from the insulated centipede ladder during use, causing minor injuries or even death. In addition, the fixing of eight wind cables requires more than 10 operating electricians to install, which is cumbersome to operate and has poor stability. Therefore, the existing use method of the insulated centipede ladder has certain safety hazards. Utility Model Content
