Description

Technical Field

[0001] The present invention relates to the technical field of tower crane selection and position adjustment, and specifically to an analysis method for visualizing lifting weights. Background Technique

[0002] Grasshopper (abbreviated as GH) is a visual programming language that runs on the Rhino platform. It is one of the mainstream software in the field of data-driven design and also overlaps with the area of interaction design. Compared with traditional design methods, the two biggest features of GH are: first, by inputting instructions, the computer can automatically generate results according to the established algorithms, and the algorithm results are not limited to models, video streaming media, and visualization solutions; second, by writing algorithm programs, mechanical repetitive operations and a large number of logical evolution processes can be replaced by the loop operations of the computer, and the scheme adjustment can also directly obtain the modified results by modifying the parameters. These methods can effectively improve the work efficiency of designers.

[0003] During the manual lifting process of existing tower cranes, a large number of calculations or manual estimations are often required to make advance estimations of the lifting of components in order to safely carry out the lifting and ensure the overall progress of the construction. However, this kind of lifting estimation not only takes time and effort but also cannot be very accurate and often makes mistakes. Therefore, Grasshopper is mostly used for assisting in calculations at present. However, the current calculation method is not yet mature, so there is an urgent need for a simple and convenient tower crane estimation method for advance estimation assistance. Summary of the Invention

[0004] The purpose of the present invention is to propose an analysis method for visualizing lifting weights to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the present invention provides the following technical solution:

[0006] An analysis method for visualizing lifting weights, the analysis method includes the following steps:

[0007] S1: Construct preset auxiliary points according to tower crane parameters;

[0008] S2: Determine the ratio of the component weight to the maximum lifting weight of the tower crane at the same distance through the preset auxiliary points;

[0009] S3: Obtain the hoisting results between each component and the tower crane according to the ratio of the component weight to the maximum lifting weight of the tower crane at the same distance.

[0010] Furthermore, constructing the preset auxiliary points is specifically as follows:

[0011] S1.1: Taking the center of the tower crane as the origin, the vertical direction of the tower crane as the Z-axis, the horizontal direction of the tower crane as the X-axis, and the direction perpendicular to the X-axis and Z-axis as the Y-axis, establish a spatial coordinate system;

[0012] S1.2: Through the Rhino operation model, construct and determine the center of gravity of the component, and at the same time, in the spatial coordinate system, determine the coordinate point corresponding to the center of gravity of the component;

[0013] S1.3: Obtain the weight corresponding to the component, and construct the preset auxiliary point according to the coordinate point corresponding to the center of gravity of the component. Specifically:

[0014]

[0015] Where: O(x, y, z) is the coordinate of the auxiliary point in the spatial coordinate system, Ox is the X-axis coordinate of the auxiliary point, Oy is the Y-axis coordinate of the auxiliary point, Oz is the Z-axis coordinate of the auxiliary point, Sx is the X-axis coordinate corresponding to the center of gravity of the component, Sy is the Y-axis coordinate corresponding to the center of gravity of the component, and q is the weight corresponding to the component.

[0016] Furthermore, determine the ratio of the weight of the component to the maximum lifting weight of the tower crane at the same distance, specifically as follows:

[0017] S2.1: Divide the preset auxiliary point;

[0018] S2.2: According to the divided preset auxiliary points, calculate the ratio of the weight of the component corresponding to different auxiliary points to the maximum lifting weight of the tower crane at the same distance. Specifically:

[0020] Where: V is the ratio of the weight of the component to the maximum lifting weight of the tower crane at the same distance, Oz is the Z-axis coordinate of the auxiliary point, Z(Ox, Oy) is the coordinate of the auxiliary point in the rectangular coordinate system, W is the rated lifting moment value of the tower crane, Ox is the X-axis coordinate of the auxiliary point, Oy is the Y-axis coordinate of the auxiliary point, q is the weight corresponding to the component, and Q1 is the maximum lifting weight of the tower crane at the same distance.

[0021] Furthermore, divide the preset auxiliary point, specifically as follows:

[0022] S2.1.1: Determine the radius size of the tower crane, and judge whether the preset auxiliary point is within the radius range of the tower crane. When the preset auxiliary point is within the radius range of the tower crane, take the preset auxiliary point as the primary auxiliary point. When the preset auxiliary point is not within the radius range of the tower crane, take the preset auxiliary point as the gray auxiliary point;

[0023] S2.1.2: Taking the central axis of the tower crane as the fixed line, construct the tower crane parameters and obtain the rotating surface;

[0024] S2.1.3: Determine whether the primary auxiliary point is located within the rotational surface according to the size of the rotational surface. When the primary auxiliary point is located within the rotational surface, the primary auxiliary point is the central auxiliary point; when the primary auxiliary point is not located within the rotational surface, the primary auxiliary point is not the central auxiliary point.

[0025] Furthermore, obtaining the rotational surface specifically includes:

[0030] S2.1.2.2: According to the tower crane parameters, obtain the rotational surface equation to determine the size of the rotational surface. The rotational surface equation is specifically:

[0032] Where: z is the value corresponding to the Z-axis in the coordinate system established with the tower crane as the origin, W is the rated lifting moment value of the tower crane, x is the value corresponding to the X-axis in the coordinate system established with the tower crane as the origin, y is the value corresponding to the Y-axis in the coordinate system established with the tower crane as the origin, s min is the minimum radius of the tower crane for lifting, s max is the maximum radius of the tower crane for lifting.

[0033] Furthermore, obtaining the hoisting result between each member and the tower crane specifically includes:

[0034] S3.1: Sort the ratios of the member weight to the maximum lifting weight of the tower crane at the same distance in ascending order;

[0035] S3.2: According to the sorting, assign different colors to the distances between the members corresponding to the ratios of the member weight to the maximum lifting weight of the tower crane at the same distance and the tower crane;

[0036] S3.3: Determine the maximum distance between the component and the tower crane according to the different colors, component weights, and auxiliary point positions.

[0037] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0038] The analysis method of the present invention obtains the ratio of the component weight to the maximum lifting weight of the tower crane at the same distance, and divides it into different areas with different colors.

Thus, it can be directly reflected by the color whether the component can be lifted by the tower crane, and further provide the most intuitive auxiliary decision-making for the staff, which is helpful for long-term use.

Therefore, once an item is defined or described in one drawing, it will not be necessary to give a further specific discussion and description thereof in the description of the subsequent drawings.

[0048] Reference Figure 1 , this embodiment provides a method for analyzing visual lifting weights, and the analysis method includes the following steps:

[0049] Step S1: Refer to Figure 2 and Figure 3 , and construct preset auxiliary points according to the tower crane parameters, specifically as follows:

[0050] Step S1.1: Taking the center of the tower crane as the origin, the vertical direction of the tower crane as the Z-axis, the horizontal direction of the tower crane as the X-axis, and the direction perpendicular to the X-axis and the Z-axis as the Y-axis, establish a space coordinate system. Refer to Figure 2 and Figure 3 , and this space coordinate system is as shown in Figure 2 and Figure 3 .

[0051] Step S1.2: Through the Rhino operation model, construct and determine the centroid of the component. Specifically, the component is regarded as a spatially homogeneous geometric body. In the Rhino operation model, after establishing this spatially homogeneous geometric body, according to the centroid calculation rule, the centroid of the component can be directly obtained.

[0052] At the same time, in the space coordinate system established in step S1.1, the vertical distance between the centroid of the component and the center of the tower crane is used as the Z-axis coordinate corresponding to the centroid of the component, the parallel distance between the centroid of the component and the center of the tower crane in the horizontal direction is used as the X-axis coordinate corresponding to the centroid of the component, and the vertical distance between the centroid of the component and the center of the tower crane in the horizontal direction is used as the Y-axis coordinate corresponding to the centroid of the component, so as to determine the coordinate point S(x, y, z) corresponding to the centroid of the component.

[0053] Step S1.3: Weigh the component directly to obtain the weight q corresponding to the component. At the same time, according to the coordinate point S(x, y, z) corresponding to the centroid of the component obtained in step S1.2, construct preset auxiliary points, specifically:

[0054]

[0055] Where: O(x, y, z) is the coordinate of the auxiliary point in the space coordinate system, Ox is the X-axis coordinate of the auxiliary point, Oy is the Y-axis coordinate of the auxiliary point, Oz is the Z-axis coordinate of the auxiliary point, Sx is the X-axis coordinate corresponding to the center of gravity of the component, Sy is the Y-axis coordinate corresponding to the center of gravity of the component, and q is the weight corresponding to the component.

[0056] Step S2: Determine the ratio of the weight of the component to the maximum lifting weight of the tower crane at the same distance through the preset auxiliary point constructed in Step S1.3, specifically as follows:

[0057] Step S2.1: Divide the preset auxiliary point constructed in Step S1.3 to obtain a gray auxiliary point, a primary auxiliary point, and a central auxiliary point, specifically as follows:

[0058] Step S2.1.1: Obtain the radius size corresponding to the tower crane, and determine whether the preset auxiliary point constructed in Step S1.3 is within the radius range of the tower crane. When the preset auxiliary point is within the radius range of the tower crane, the preset auxiliary point is the primary auxiliary point. When the preset auxiliary point is not within the radius range of the tower crane, the preset auxiliary point is the gray auxiliary point.

[0059] Step S2.1.2: Take the central axis of the tower crane as the fixed line, construct the tower crane parameters, and obtain the rotational surface, specifically as follows:

[0060] Step S2.1.2.1: Take the central axis of the tower crane as the fixed line and construct the tower crane parameters, specifically:

[0061]

[0062] W = S × Q

[0063] Where: z is the value corresponding to the Z-axis in the coordinate system with the tower crane as the origin, W is the rated lifting moment value of the tower crane, x is the value corresponding to the X-axis in the coordinate system with the tower crane as the origin, y is the value corresponding to the Y-axis in the coordinate system with the tower crane as the origin, s min is the minimum radius of the tower crane for lifting, s max is the maximum radius of the tower crane for lifting, S is the horizontal distance between the center of gravity of the lifting component and the center point of the tower crane, and Q is the lifting weight.

[0064] Reference Figure 5 , Figure 5 is the function image corresponding to the rated lifting moment value W of the tower crane. It can be seen from the image that the horizontal distance S between the center of gravity of the lifting component and the center point of the tower crane is inversely proportional to the lifting weight Q. That is to say, the closer the distance, the greater the weight, and the farther the distance, the smaller the weight.

[0065] Step S2.1.2.2: Based on the tower crane parameters obtained in step S2.1.2.1, obtain the equation of the rotating surface and determine the size of the rotating surface. The specific equation of the rotating surface is as follows:

[0066]

[0067] where: z is the value corresponding to the Z-axis in the coordinate system established with the tower crane as the origin, W is the rated lifting moment value of the tower crane, x is the value corresponding to the X-axis in the coordinate system established with the tower crane as the origin, y is the value corresponding to the Y-axis in the coordinate system established with the tower crane as the origin, s min is the minimum radius of the tower crane's lifting, s max is the maximum radius of the tower crane's lifting.

[0068] Step S2.1.3: Determine the size of the rotating surface according to the equation of the rotating surface in step S2.1.2.2. Judge whether the primary auxiliary point obtained in step S2.1.2.1 is located within the rotating surface. When the primary auxiliary point obtained in step S2.1.2.1 is located within the rotating surface, the primary auxiliary point obtained in step S2.1.2.1 is the central auxiliary point. When the primary auxiliary point obtained in step S2.1.2.1 is not located within the rotating surface, the primary auxiliary point obtained in step S2.1.2.1 is not the central auxiliary point.

[0069] Step S2.2: Calculate the ratio of the weight of the component corresponding to different auxiliary points to the maximum lifting weight of the tower crane at the same distance according to the divided preset auxiliary points. Specifically:

[0070]

[0071] where: V is the ratio of the weight of the component to the maximum lifting weight of the tower crane at the same distance, Oz is the Z-axis coordinate of the auxiliary point, Z(Ox, Oy) is the coordinate of the auxiliary point in the rectangular coordinate system, W is the rated lifting moment value of the tower crane, Ox is the X-axis coordinate of the auxiliary point, Oy is the Y-axis coordinate of the auxiliary point, q is the weight corresponding to the component, and Q1 is the maximum lifting weight of the tower crane at the same distance.

[0072] Step S3: Obtain the hoisting result between each component and the tower crane according to the ratio V of the weight of the component to the maximum lifting weight of the tower crane at the same distance obtained in step S2.2, as follows:

[0073] Step S3.1: Sort the ratios of the weight of the component to the maximum lifting weight of the tower crane at the same distance in ascending order. It should be noted that the order of the ratios of the weight of the component to the maximum lifting weight of the tower crane at the same distance is not fixed to be only in ascending order. It can also be sorted in descending order.

[0074] Step S3.2: According to the sorting determined in Step S3.1, assign different colors to the distance between the component weight and the ratio of the maximum lifting weight of the tower crane at the same distance. Refer to Figure 4 , Figure 4 In [reference], area A indicates that the distance between the component and the tower crane center is between the minimum lifting radius and the maximum lifting radius, and the component can be lifted by the tower crane. At the same time, the lower it is, the easier it is to lift, and the higher it is, the closer it is to the maximum lifting weight. Area B indicates that the distance between the component and the tower crane center is between the minimum lifting radius and the maximum lifting radius, and the component cannot be lifted by the tower crane. At the same time, the lower it is, the smaller the value exceeding the maximum lifting weight, and the higher it is, the larger the value exceeding the maximum lifting weight. Area C indicates that the distance between the component and the tower crane center exceeds the maximum lifting radius.

[0075] Step S3.3: According to different colors, component weights, and the positions of auxiliary points, the maximum distance between the component and the tower crane can be determined. Specifically, the lifting results of each component under the selection of the tower crane model and the spatial position can be obtained, which can provide a real-time visual reference basis for the selection of the tower crane model and the adjustment of the position.

[0076] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
