4. The inclined rope bridge type rescue method for the trapped people on the high-voltage transmission line pole tower as claimed in claim 1, characterized in that the conductors of the trapped people are arranged horizontally: rescue workers enter the two sides of the position of the trapped person through the ground wire or the optical cable above the lead by adopting a ground wire pulley to rescue or enter the position near the trapped person from the ground in a mode of an insulating rope ladder and the ground wire pulley to rescue.
5. The inclined rope bridge type rescue method for the trapped people on the high-voltage transmission line pole tower as claimed in claim 1, characterized in that the vertical arrangement mode of the wires where the trapped people are located is as follows: when the trapped person is on the lower phase lead, the rescue person enters the position of the trapped person through the middle phase lead for rescue; when the trapped person is in the middle phase conductor, the rescue person enters the position of the trapped person through the upper phase conductor for rescue; when the trapped person is on the upper phase lead, the rescue person enters the position of the trapped person through the ground or the optical cable above the lead for rescue.
6. The rescue method of the high-voltage transmission line pole tower trapped people by the inclined rope bridge, according to claim 1, is characterized in that if the situation that the transportation is inconvenient when the people reach the inclined pulling terminal but the vehicles can get close to the ground at the midway position is convenient, a way of vertically descending the people from the midway position is adopted, and the method specifically comprises the following steps:
after high-altitude rescue personnel carrying trapped personnel descend to a preset position along the inclined guide rail ropes, locking a descending protector, respectively establishing middle anchor points on the two guide rail ropes, connecting the anchor points by using two main locks with the same type, and hanging a rescue main rope and a safety rope for descending into the two main locks for steering;
the high-altitude rescue personnel remove the main lock of the safety belt connected with the guide rail rope and take down the pulley on the guide rail rope in a lifting way;
the high-altitude rescue personnel carrying the trapped personnel vertically descend to the ground along the rescue rope, and the ground personnel receive the rescue personnel to complete the rescue.
