The core of this transformation is to improve construction efficiency, reduce costs, and improve project quality and safety.

[0003] The installation and disassembly of construction machinery and equipment is an important part of construction, which directly affects the progress and safety of the project. The traditional method of drawing disassembly drawings of construction elevators mainly relies on manual operation. Technicians use CAD software to manually draw drawings according to construction requirements and equipment characteristics. This method relies on the experience and skills of technicians, manually drawing basic graphics, adding dimensions, annotations and layer information, and making detailed adjustments and corrections to ensure the accuracy and compliance of the drawings. It takes a lot of time and effort to complete, and the efficiency is low. It usually takes hours or even days to draw a drawing, especially in complex construction environments, and it is prone to errors.

[0004] Therefore, it is necessary to propose an intelligent drawing method and system for disassembly drawings of construction machinery and equipment. Summary of the invention

[0037] The following is a further detailed description of a construction machinery and equipment disassembly drawing intelligent drawing method and system provided by the present invention in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer in conjunction with the following description. It should be noted that the accompanying drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0038] Embodiment 1

[0039] The intelligent drawing method for disassembly drawings of construction machinery and equipment provided in this embodiment utilizes the secondary development function of CAD software and combines it with machine learning algorithms to realize intelligent drawing frame drawing, drawing recognition, automatic drawing cutting and annotation, and other functions, and automatically draws the disassembly plan and disassembly elevation drawings of the construction hoist, so as to improve the efficiency and accuracy of drawing disassembly drawings of the construction hoist. Figures 1 to 4 As shown, the method comprises the following steps:

[0040] S1. Obtain project information, construction lifting equipment information and disassembly equipment information, and automatically generate adapted general layout drawing frame 1, disassembly plan drawing frame 2 and elevation drawing frame 3 according to the pre-designed drawing frame style;

[0041] S2. Import the master plan layout into the master plan layout frame 1 Figure 4 , using machine deep learning technology to identify the overall layout Figure 4 The model of the construction elevator 6 is obtained, the base point coordinates of the construction elevator 6 are obtained, and the general plan layout is arranged according to the base point coordinates of the construction elevator Figure 4 Divided into multiple disassembly areas;

[0042] S3. The disassembly areas divided by the general plan layout are respectively set in the disassembly plan frame 2, the preset disassembly equipment blocks are retrieved and placed around the elevator, and the linear dimensions of the disassembly equipment and construction elevator blocks are marked according to the base point coordinates of the disassembly equipment blocks and the base point coordinates of the construction elevator;

[0043] S4. In the elevation drawing frame 3, the elevation drawings of the building structure 5 and the construction elevator 6 are loaded, a number of vertical nodes are preset, the components of the construction elevator above a vertical node are deleted each time, and the corresponding elevation drawings after each deletion are drawn in sequence.

[0044] Project information includes project name, construction unit, design unit, equipment disassembly unit, drawing information, etc. It can be collected by manual input, and of course it can also be identified from existing files through text recognition.

[0045] Construction hoisting equipment information includes the construction hoist model and construction hoist parameters. Construction hoist is a vertical transportation equipment, mainly used for vertical transportation of materials and personnel in construction. It is a temporary, movable, vertically operating transportation machinery, usually including a cage (car), a guide rail frame, a wall frame and a power mechanism. The bottom of the guide rail frame is fixed to the bottom foundation by anchor bolts. The guide rail frame includes several standard sections spliced ​​up and down in sequence. The guide rail frame is fixedly connected to the building structure through several layers of wall frames. The cage can move up and down along the guide rail frame through the power mechanism.

[0046] In order to use machine deep learning technology to identify the model of the construction elevator in the general layout drawing, a construction elevator retrieval module can be set up first and a convolutional neural network or other machine learning model algorithm can be built in. A large amount of relevant information on the general layout drawings and construction elevator parameters can be collected in advance, and the general layout drawings can be preprocessed, such as grayscale, binarization, and noise removal. After that, the features of the construction elevator (shape, size, and label text) are extracted, and the model is trained. After the training is completed, the construction elevator retrieval module can automatically identify the construction elevator model on the new general layout drawing. After the construction elevator model is determined, the composition structure of the construction elevator, including which components, can be obtained, and the blocks of the corresponding components can be retrieved, so that when it is subsequently dismantled, it can be deleted according to the block as the minimum deletion unit. For example, when the guide frame is dismantled, one or several standard section blocks are deleted each time.

[0047] When the general layout drawing is in the CAD primitive format, the base point coordinates of the construction elevator can be obtained by collecting the coordinate values ​​in the CAD drawing. When the general layout drawing is in the image format, the pixel coordinates of the construction elevator can be obtained by collecting pixel points. Based on the proportional relationship between the pixel coordinates and the CAD coordinates, the pixel coordinates are converted into base point coordinates.

[0048] The intelligent drawing method for disassembly drawings of construction machinery and equipment provided in this embodiment can automatically generate a general layout drawing frame, a disassembly plan drawing frame and a facade drawing frame, and call the general layout drawing into the general layout drawing frame, divide the general layout drawing into disassembly areas according to the construction elevator, and then display the divided disassembly areas in the disassembly plan drawing frame respectively, and place the blocks of the disassembly equipment to form a disassembly plan drawing centered on the elevator, and then set the elevation drawing of the construction elevator in the elevation drawing frame, and draw multiple elevation drawings corresponding to the dismantling process of the construction elevator by deleting the blocks of the construction elevator step by step, thereby significantly improving the efficiency and accuracy of drawing drawings.

[0049] In a specific embodiment, the general plan layout is divided into a plurality of disassembly areas according to the coordinates of the construction elevator base points, and the specific steps are as follows:

[0050] S21. Calculate the Euclidean distance between the base points of each pair of lifts d ; d =( x 2- x 1) 2 +( y 2- y 1) 2 ,in( x 1, y 1) ( x 2, y 2) are the coordinates of the two lift base points;

[0051] S22. Convert each point of the CAD drawing of the general layout plan into pixel coordinates according to the scale. For example, if the coordinates of a point on the drawing are (100, 200), and the scale is set to 1 unit = 10 pixels, then the pixel coordinates of the point are (1000, 2000); then use a clustering algorithm (such as a K-means algorithm) to iteratively calculate the distances between each two points and adjust the cluster centers, and assign these points to the nearest cluster center until the cluster center is stable or the preset number of iterations is reached, and finally determine each cluster center as the base point position of the disassembly area, ensuring that each area contains only one construction elevator, thereby providing a clear area division for the disassembly of the construction elevator;

[0052] S23. Obtain the coordinates of the boundary points of each disassembly area, use the boundary points fitted by the least squares method to create a regular clipping boundary polygon, call the CLIP command, and complete the disassembly area division of the general plan layout drawing, ensuring that each disassembly area is centered on the elevator base point and that each area is relatively independent.

[0053] In a specific embodiment, a disassembly equipment positioning module is provided, and a database is established in the disassembly equipment positioning module using MySQL technology to store graphic primitive modules of different models of disassembly equipment. Disassembly equipment is a series of tools and machinery used to disassemble construction elevators. These equipment are used to safely and efficiently dismantle the various components of the construction elevators after the construction is completed or when the equipment needs to be transferred to other construction sites. The disassembly equipment generally includes components such as booms and lifting equipment. According to the obtained disassembly equipment model, the disassembly equipment positioning module can automatically retrieve the graphic primitive module of the corresponding model of disassembly equipment and draw it in the disassembly plan in CAD.

[0054] In a specific embodiment, each time the components of the construction elevator above a vertical node are removed, the components of the construction elevator mainly include a track frame 9 and a wall frame 8. For example, the vertical node is set to the vertical coordinate of the top of the facade structure of the building and the vertical coordinate of the bottom of the wall frame. Figure 4As shown, the parts of the construction elevator above a vertical node are deleted each time, and the corresponding elevation drawings after each deletion are drawn in sequence, which specifically includes the following steps:

[0055] S41. Delete the components of the construction elevator whose vertical coordinates are greater than the vertical coordinates of the top of the facade structure, mainly the top head frame of the construction elevator and the standard section blocks of the top track frame;

[0056] S42. Delete the top wall frame and the standard section block of the track frame whose vertical coordinate is greater than the top wall frame; in actual construction, use the lifting rod of the lift to dismantle the top wall frame, use the lifting rod of the dismantling equipment to lift the standard section section by section, and dismantle the guide rail frame and the wall frame section by section from top to bottom;

[0057] S43. Delete the second wall-mounted frame and the standard section block of the track frame whose vertical coordinate is greater than that of the second wall-mounted frame; in actual construction, use the lifting rod of the lift itself to dismantle the second wall-mounted frame, use the lifting rod of the dismantling equipment to lift the standard section section by section, and dismantle the guide rail frame and the second wall-mounted frame section by section from top to bottom;

[0058] S43. Remove the wall-mounted brackets and the corresponding track rack standard section blocks one by one from top to bottom until only 3 to 4 track rack standard section blocks remain.
