The step pitch of the same standard knot at the joint is composed of two standard knots, for example, one standard knot can be divided into three small sections of L1, one or more L and L2 by a plurality of connecting structures, L1+ L2 is L, different standard knots have different step pitches, for example, a first step pitch and a second step pitch, one type of standard knot 1 and the lower conversion knot 6 corresponding to the standard knot have the same step pitch, and different standard knots are connected to form a third step pitch, for example, the lower conversion knot 6 and the second type of standard knot 2 form a third step pitch at the joint, that is, the L1 section of one standard knot is connected with the L2 section of another standard knot to form the third step pitch. Accordingly, the jacking mechanism, i.e., the jacking cylinder, needs to be able to realize three different jacking distances (extended or retracted distances) so as to allow the climbing frame 4 to move at the corresponding positions at the first step interval, the second step interval, and the third step interval.
Optionally, the difference between the cross section of the first-type standard knot 1 and the cross section of the second-type standard knot 2 is less than five thousandths of a circle. The difference of the section sizes of the two different standard knots cannot be overlarge, so that the upper conversion knot and the lower conversion knot can be conveniently designed on one hand, and the climbing frame 4 can be installed and sleeved on the two standard knots on the other hand.
Specifically, an inlet is arranged on the side portion of the climbing frame 4, and the first introducing mechanism 7 and the second introducing mechanism 8 are located on the side of the side portion of the climbing frame 4 where the inlet is arranged. The climbing frame 4 is a structure composed of a plurality of beams, the inside of the climbing frame is a channel allowing the standard knot to pass through, so that the climbing frame 4 is allowed to move on a mounting knot (comprising the standard knot and a conversion knot), in addition, the side part of one side is provided with an inlet, so that the mounting knot is allowed to pass through the inlet to enter the channel, correspondingly, a first introducing mechanism 7 arranged on the jacking knot 3 and a second introducing mechanism 8 arranged on the upper conversion knot 5 are positioned on the inlet side, so that the corresponding standard knot or conversion knot can be moved in the climbing frame 4.
Alternatively, the first introduction mechanism 7 can perform lifting and translation operations, and the second introduction mechanism 8 can perform lifting and translation operations. The first introduction means 7 and the second introduction means 8 can be lifting devices, such as cranes or the like, which can lift the standard or changeover joint from the ground and can move it horizontally into the climbing frame 4.
