1results about How to "Climbing safety" patented technology

This utility model relates to the field of power transmission tower technology, specifically a long-span power transmission tower, including a support, a frame, and a climbing device. The frame is fixed to the upper surface of the support, and the climbing device is installed in the inner wall of the support. The climbing device includes an upper ladder, which is fixedly connected to the frame. Slide grooves are provided at both ends of the upper ladder, and sliders are slidably connected to the inner walls of the slide grooves at both ends of the upper ladder. A lower ladder is fixedly connected to the surface of the sliders. A motor is fixedly connected to the upper surface of the frame, and a round rod is fixedly connected to the drive end of the motor. The end of the round rod away from the motor is rotatably connected to the frame. A coil is fixedly connected to the surface of the round rod, and a pull rope is wound around the surface of the coil. This utility model aims to enable maintenance personnel to conveniently and safely climb the tower, while also preventing unauthorized personnel from climbing. The motor-driven retractable pull rope mechanism allows the lower ladder to be raised and lowered flexibly. It can be lowered for personnel to climb during maintenance and retracted after maintenance to prevent unauthorized personnel from touching it, thus balancing practicality and safety.
