[0003] In the prior art, the docking arms of the crossing frame are docked by means of push blocks arranged on the outside, which speeds up the docking speed and improves the efficiency of construction. Before the docking is completed, the docking arms on both sides of the object to be crossed are equipped with sealing rods to achieve semi-sealed nets. After the docking is completed, full sealing nets are directly achieved. During this period, the object to be crossed does not need to be powered off, which improves the safety and efficiency of live crossing construction of transmission lines.
