[0037] Please refer to Figures 1 to 4 The tower crane wall installation and disassembly planning method comprises the following steps:

[0038] First, execute step S1 to determine a set of allowed wall attachment points on the tower crane;

[0039] Specifically, S1 includes the following steps:

[0040] S11: Take the intersection of the building's wall-attachable range and the tower crane's wall-attachable range;

[0041] S12: The set obtained by discretizing the intersection with a step size of 0.1 meters is the set of allowed wall attachment points.

[0042] Example 1: Please refer to Figure 3 , Figure 3In the figure, the building can be attached to the wall range {M} and the tower crane can be attached to the wall range {B}. The intersection of the two segments M and the two segments B is 25~25.6 and 26~26.2, and the set of allowed wall attachment points C = {25,25.1,25.2,25.3,25.4,25.5,25.6,26,62.1,26.2} is obtained.

[0043] Next, executing step S2, determining the point of the new wall attachment according to the minimum height of the new wall attachment and the set of allowed wall attachment points;

[0044] Specifically, S2 includes the following steps:

[0045] S21: Calculate the minimum height Pmin of the new wall according to the cantilever height specified in the tower crane instruction manual and the current height of the tower crane; wherein, in S21, the minimum height Pmin of the new wall is calculated based on the following formula:

[0046] Pmin=Ht-Hx; Pmin is the minimum height of the newly attached wall; Ht is the current height of the tower crane; Hx is the cantilever height.

[0047] S22: Determine the point P0 of the new wall based on the following formula:

[0048] P0=min({x|x∈C and x>Pmin}); where P0 is the new wall attachment point, C is the set of allowed wall attachment points, and Pmin is the minimum height of the new wall attachment. In other words, the process of determining the new wall attachment point P0 is: select the smallest point that meets the minimum height value from the set of allowed wall attachment points as the new wall attachment point P0; if there is no point that meets the requirements in the set of allowed wall attachment points, then select the smallest point in the set of allowed wall attachment points that is greater than the minimum height value Pmin of the new wall attachment as the new wall attachment point.

[0049] Example 2: The current height of the tower crane is 91 meters, and the cantilever height specified in the manual is 33.6 meters, then Pmin = 57.4m, but this height is not in C, so the smallest point greater than Pmin, that is, 57.8m, is selected as the new wall attachment position.

[0050] Next, step S3 is executed, (adjusting the existing attached wall) firstly verifies whether the second to last existing attached wall meets the requirements of the attached wall spacing. If so, there is no need to adjust the existing attached wall, and the current result is directly output; otherwise, the connection state of each existing attached wall is traversed in turn, and each step of traversal verifies whether the requirements of the attached wall spacing are met. If so, the final result is output, otherwise, S4 is executed; wherein the connection state includes: a tightened state and a loosened state;

[0051] Example 3: Please refer to Figure 4 , Figure 4Except for the newly added attachment wall, there are already 2 attachment walls for the tower crane, located at P1 = 46.4m and P2 = 25.6m respectively. Among them, the spacing requirements are not met between P1 and P0, so try to loosen it. Traverse the four states of the two existing attachment walls, namely <tight|tight>, <tight|loose>, <loose|tight>, <loose|loose>. After checking, it is found that the state of <loose|tight> meets the requirements, that is, P1 is loosened and P2 remains. This plan is the final plan.

[0052] Next, execute step S4 (try to add attachment walls), determine the points where attachment walls can be added, and add an attachment wall at each point where an attachment wall can be added; specifically, the points where attachment walls can be added can be determined based on the following formula:

[0053] {Pnew} = {x|x ∈ C and x < P0}; where Pnew is the point where the attachment wall is added; C is the set of allowable attachment wall points; P0 is the point of the new attachment wall.

[0054] Embodiment 4: The points where attachment walls can be added are {57.7, 57.6, 57.5,...}. Traverse these points and add an attachment wall ( Figure 4 ), and traverse the four states of the two existing attachment walls as above. If the check is satisfied, it is the final plan.

[0055] Next, execute step S5, traverse the connection states of each existing attachment wall in turn, and check whether the spacing requirements are met with the newly added attachment wall at each step of traversal. If satisfied, output it as the final result; otherwise, feedback this situation to the technical personnel, and the technical personnel will prepare an over-limit plan and submit it to the tower crane manufacturer for approval.

[0056] It should be noted that for the foregoing method embodiments, for the sake of simple description, they are all expressed as a series of action combinations. However, those skilled in the art should know that the present application is not limited by the described action sequence, because according to the present application, certain steps can be performed in other sequences or simultaneously.

[0057] The present invention has the following advantages:

[0058] 1) The tower crane attachment wall installation and removal planning method comprehensively considers factors such as attachment wall spacing and tower crane cantilever height, rather than relying on the experience of technical personnel, which can ensure the stability of the tower crane during construction, reduce safety risks, and improve construction efficiency;
