2) in climbing, the tower body moves upwards relative to the upper trolley and the lower trolley under the jacking action of the trolley oil cylinder, when the four clamping seats reach the upper layer of stepping, the pin shafts (37) of the clamping seats are inserted into the shaft holes (205) of the tower barrel to complete lifting operation, the stroke of one stepping is h2, and the tower body enters a six-point supporting state; the tower body moves upwards under the action of the trolley oil cylinder, the tower body enters a five-point supporting state, the main load is borne by the lower trolley at the moment, and the upper trolley pin shaft (29) is changed from e1 point supporting to e2 point supporting, so that a lifting working cycle is completed; in the climbing operation process, two-point support, five-point support and six-point support are alternately carried out;
3) the descending process work flow is opposite to the climbing process work flow.
