The guardrail cross rod of the passage platform A is installed on the outer side of the guardrail vertical rod, and the guardrail cross rod of the passage platform B is installed on the inner side of the guardrail vertical rod, so that the guardrail cross rod does not interfere when the movable passage mechanism rotates upwards. After the above assembly is completed, the passage platform A and the guardrail of the fixed passage mechanism are fixedly connected with the T-shaped plate and the climbing frame body through bolts. Two inclined pull rods are fixed at two ends of the passage platform A through bolts respectively, and are fixed on the climbing frame body in parallel correspondence through bolts at the other ends. A power mechanism is installed on the climbing frame body below the passage platform, a double-groove fixed pulley is installed on the climbing frame body above the passage platform, two steel wires are hung at two ends of a hook of an electric hoist, and the other ends of the two steel wires pass through the double-groove fixed pulley and are hung at two ends of the passage platform B.
