Description

Technical Field

[0001] This invention relates to the field of digital construction technology, and in particular to a BIM-based method and system for simulating heavy hoisting equipment. Background Technology

[0002] In the electromechanical installation of tall steel structure factory buildings (usually referring to factory buildings with a spatial span of more than 30m), the hoisting and installation of heavy equipment (such as large fans, heat exchangers, etc.) is one of the core links.

[0003] In existing technologies, heavy equipment hoisting largely relies on two-dimensional drawings for construction guidance, which presents the following prominent problems: First, steel structures are prone to deflection deformation during construction, and traditional hoisting simulations fail to effectively integrate steel structure deformation parameters with electromechanical equipment load parameters, leading to a disconnect between the hoisting path planning and the actual structural condition on site. Second, steel structure models and electromechanical models are constructed separately by different disciplines, resulting in inconsistent information interfaces and delayed data synchronization, which can easily cause collisions and conflicts between the hoisting path and electromechanical pipelines and steel structure components. Third, there is a lack of precise analysis of the stress state of the steel structure during hoisting, relying solely on experience to judge structural safety, which can easily lead to damage to the steel structure or insufficient hoisting accuracy due to overload. Fourth, the hoisting scheme lacks an integrated simulation and verification mechanism, resulting in high rework rates, low efficiency, and difficulty in preventing safety risks in advance. These problems lead to poor coordination, prominent safety hazards, and low construction efficiency in the hoisting of heavy equipment in tall steel structure factory buildings, severely hindering the digital and industrial transformation of electromechanical installation in industrial buildings.

[0004] Therefore, how to achieve digital and precise simulation of the hoisting of heavy equipment in tall steel structure factory buildings, avoid collisions and structural safety risks in advance, and improve the efficiency, accuracy and safety of hoisting construction is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

Furthermore, in the description of this invention, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0013] Figure 1 This is a flowchart illustrating the BIM-based heavy lifting equipment simulation method provided in this embodiment of the invention.

[0014] like Figure 1 As shown, the BIM-based heavy lifting equipment simulation method provided in this embodiment of the invention mainly includes the following steps: 101. Obtain the architectural design parameters and electromechanical system requirements parameters of the steel structure workshop to be constructed; Specifically, parameter surveys and data collection can be carried out on the tall steel structure factory buildings to be constructed: the architectural design parameters should focus on collecting structural characteristic parameters such as the span, design load, and allowable deflection of the factory buildings to ensure coverage of core indicators related to steel structure construction and deformation; the electromechanical system requirements parameters mainly include the specifications and dimensions of electromechanical pipelines, the weight, dimensions, and installation location of heavy equipment, etc., to provide data support for subsequent model construction.

[0015] 102. Based on the architectural design parameters and the electromechanical system requirements parameters, construct an integrated BIM model that includes a steel structure model and an electromechanical model; The integrated BIM model includes deformation parameters of the steel structure and load parameters of the electromechanical equipment; this step can be implemented in the following way: a1. Establish an initial steel structure model based on the architectural design parameters; the architectural design parameters include the span, load, and deflection characteristics of the factory building; Specifically, based on the collected architectural design parameters (span, load, deflection characteristics, etc.), an initial model of the steel structure can be built using BIM modeling software. This model needs to accurately reproduce the component layout, node connection method, and allowable deformation range of the steel structure of the factory building to ensure a true mapping of structural characteristics.

[0016] a2. Establish an initial electromechanical model based on the electromechanical system requirement parameters; the electromechanical system requirement parameters include electromechanical pipeline specifications and equipment parameters; Specifically, based on the electromechanical system requirements parameters (electromechanical pipeline specifications, equipment parameters, etc.), an initial electromechanical model can be built to fully present the routing, pipe diameter, support and hanger positions of electromechanical pipelines, as well as the three-dimensional dimensions and installation coordinates of heavy equipment, ensuring the integrity of the electromechanical system layout.

[0017] a3. Establish collaborative modeling standards to merge the initial steel structure model and the initial electromechanical model to form the integrated BIM model.

[0018] Specifically, the collaborative modeling standard is mainly used to standardize the data format, parameter definitions, and interface rules of the two initial models, resolving information incompatibility issues caused by multidisciplinary modeling. This standard integrates the data of the initial steel structure model and the initial electromechanical model, enabling information exchange between the two models within the same BIM environment. Ultimately, this results in an integrated BIM model containing steel structure deformation parameters and electromechanical load parameters, providing a unified and accurate model foundation for the hoisting simulation and stress analysis in claim 1. This step can be implemented as follows: a31. Establish a unified data exchange format as a general protocol for data interaction between the initial steel structure model and the initial electromechanical model; A unified data exchange format can be established, which serves as a common protocol for data interaction between the initial steel structure model and the initial electromechanical model. This ensures that data from different professional models can be transmitted and parsed smoothly, avoiding information loss or unrecognizable issues caused by differences in data formats.

[0019] a32. Formulate parameter mapping rules, which are used to define the correspondence and conversion logic between the structural parameters in the initial steel structure model and the equipment parameters in the initial electromechanical model. The structural parameters include at least node coordinates and allowable deformation, and the equipment parameters include at least support and hanger positions and equipment loads. Specifically, the correspondence between the core structural parameters (such as node coordinates and allowable deformation) in the initial steel structure model and the key equipment parameters (such as support and hanger positions and equipment loads) in the initial electromechanical model can be clearly defined, and the conversion logic between parameters can be defined. For example, the equipment load parameters can be converted into the stress parameters of the steel structure nodes, and the allowable deformation of the steel structure can be converted into the precision control parameters for the installation of electromechanical pipelines, so as to achieve the coordinated association of the two types of parameters.

[0020] a33. Based on the data exchange format and the parameter mapping rules, create an association between the nodes of the initial steel structure model and the support points of the initial electromechanical model; Specifically, based on the aforementioned unified data exchange format and parameter mapping rules, a one-to-one correspondence can be established between key nodes (such as load-bearing nodes and easily deformable nodes) in the initial steel structure model and key support points such as equipment support and pipeline support points in the initial electromechanical model. This allows the deformation state of the steel structure to be transmitted to the electromechanical system in real time, and the load of the electromechanical equipment to be accurately fed back to the steel structure.

[0021] a34. Based on the aforementioned relationship, the data of the initial steel structure model and the initial electromechanical model are merged and uniformly expressed to generate the integrated BIM model.

[0022] Specifically, based on the established relationships, the geometric data, attribute parameters, constraints, and other information of the two initial models can be uniformly integrated and expressed to eliminate data redundancy and conflicts, ultimately generating an integrated BIM model that deeply integrates structural and electromechanical information, ensuring that the model can support subsequent core processes such as hoisting simulation and stress analysis.

[0023] This embodiment refines the implementation method of collaborative modeling standards by unifying data exchange formats, formulating parameter mapping rules, and creating node association relationships. It solves the technical bottlenecks of poor cross-disciplinary model data interaction and parameter mismatch. It realizes the precise association and data fusion of steel structure and electromechanical system parameters, enabling the integrated BIM model to have "deformation-load" linkage response capability, greatly improving the model's collaboration and accuracy, and providing a solid technical foundation for the collaborative analysis of structure and electromechanical systems during subsequent hoisting.

[0024] 103. In the integrated BIM model, the hoisting process is simulated based on the hoisting path planning of heavy equipment, and the steel structure stress analysis is performed on the hoisting process based on the deformation parameters and the load parameters. Specifically, in the integrated BIM model, the initial hoisting path is planned by combining the factory space layout, the target location of equipment installation, and the on-site construction conditions; the complete movement process of heavy equipment from the lifting point to the target installation point is simulated through the model visualization function, and the collision between the path and existing components such as steel structure components and electromechanical pipelines in the model is detected in real time; at the same time, based on the preset steel structure deformation parameters and electromechanical equipment load parameters in the model, the stress state of the steel structure during hoisting is calculated using mechanical analysis methods to determine whether the structure is within the safe bearing range.

[0025] In a specific implementation process, the hoisting process is simulated based on the hoisting path planning of heavy equipment, including: defining the three-dimensional model of the heavy equipment, the lifting point, the target installation point, and the hoisting equipment parameters in the integrated BIM model; simulating the movement trajectory of the heavy equipment from the lifting point to the target installation point, and detecting the collision between the movement trajectory and existing components in the integrated BIM model to obtain the result of the hoisting process simulation.

[0026] Specifically, basic parameters can be defined in the integrated BIM model: import or create a 3D model that matches the actual size and weight of the heavy equipment to ensure the model's authenticity; determine the lifting point based on on-site construction conditions (such as the size of the hoisting site and the placement of the crane), and determine the target installation point based on the design drawings; input hoisting equipment parameters (such as the crane's lifting weight, operating radius, boom length, etc.) to provide equipment constraints for trajectory simulation.

[0027] Next, motion trajectory simulation and collision detection can be performed: Based on the defined lifting point, target installation point, and lifting equipment parameters, the initial motion trajectory of the heavy equipment is automatically generated in the integrated BIM model; through the collision detection function of the BIM software, the equipment is tracked in real time at every position on the motion trajectory, and it is detected whether there is spatial overlap (i.e., collision) between the equipment and existing components such as steel structure components, electromechanical pipelines, and other equipment in the model; if a collision is detected, the collision location, collision component type, and other information are recorded; if no collision is detected, a collision-free motion trajectory is generated, and finally, a hoisting process simulation result containing the trajectory path and collision detection results is formed.

[0028] This embodiment achieves advance rehearsal of the hoisting process by accurately defining hoisting-related parameters and performing visual trajectory simulation; the collision detection function can detect conflicts in the hoisting path in advance, avoiding on-site collisions and rework caused by improper path planning in traditional construction; the simulation results provide an intuitive and accurate basis for optimizing and adjusting the hoisting path, greatly improving the rationality and safety of hoisting path planning.

[0029] In a specific implementation process, a stress analysis of the steel structure is performed on the hoisting process based on the deformation parameters and the load parameters, including: The dynamic load is applied to the steel structure model of the integrated BIM model; Using the finite element method, the mechanical response values ​​of the steel structure under the dynamic load are calculated under the boundary conditions corresponding to the deformation parameters; the mechanical response values ​​include stress, strain, and displacement. The structural stress analysis results are generated by comparing the mechanical response value with the corresponding safety threshold.

[0030] Specifically, dynamic loads can be applied: the dynamic loads generated during the hoisting of heavy equipment (including the equipment's own weight, impact forces during hoisting, inertial forces, etc.) are precisely applied to the corresponding nodes of the steel structure model based on the contact relationship between the equipment and the steel structure in the integrated BIM model, ensuring the authenticity of load transfer.

[0031] Next, mechanical response calculations are performed: using the finite element analysis method, the pre-set steel structure deformation parameters (such as allowable deflection, deformation constraints, etc.) in the integrated BIM model are used as boundary conditions. The mechanical response values ​​of each component and node of the steel structure during the hoisting process are solved through numerical calculation, including stress (internal strength of the component), strain (degree of deformation of the component) and displacement (position offset of the component), which comprehensively reflects the stress state of the steel structure under the hoisting load.

[0032] Then, the structural stress analysis results are generated: the calculated mechanical response values ​​are compared one by one with the preset safety thresholds (determined according to steel structure design standards, material strength grades, etc.) to determine whether the stress of each component and node is within the safe range; if all mechanical response values ​​are within the safety thresholds, the steel structure is determined to be safe; if some response values ​​exceed the safety thresholds, the corresponding dangerous components and nodes are marked, forming a structural stress analysis result that includes safety judgment conclusions, dangerous area identification, and detailed stress data.

[0033] 104. Based on the results of the hoisting process simulation and the results of the steel structure stress analysis, generate an equipment installation plan and a structural safety verification report.

[0034] Specifically, if the simulation result of the hoisting process indicates that no collision was detected and the structural stress analysis result indicates that the mechanical response value is within the safety threshold, then the hoisting path planning is deemed valid, and an equipment installation plan and safety verification report containing the hoisting path planning are generated; if the simulation result of the hoisting process indicates that a collision was detected or the structural stress analysis result indicates that the mechanical response value exceeds the safety threshold, then the hoisting path planning is adjusted, and the simulation and analysis are performed again.

[0035] Specifically, firstly, result determination is carried out: the simulation results of the hoisting process and the stress analysis results of the steel structure are comprehensively determined to form two determination scenarios.

[0036] Scenario 1: If no collisions are detected during the hoisting simulation, and all mechanical response values ​​in the structural stress analysis are within the safety threshold, then the current hoisting path plan meets both spatial avoidance requirements and structural safety requirements, and is therefore deemed valid. Based on this valid path, a detailed equipment installation plan is generated, including practical aspects such as hoisting procedures, personnel configuration, equipment operation specifications, and timeline arrangements. Simultaneously, a structural safety verification report is generated, covering hoisting load parameters, steel structure mechanical response data, and safety assessment conclusions, serving as the basis for construction safety review.

[0037] The second scenario: If a collision is detected during the hoisting simulation (regardless of the collision location and severity), or if the structural stress analysis results show that the mechanical response value exceeds the safety threshold, it indicates that the current hoisting path poses a safety risk or has construction feasibility issues, and the path planning is deemed invalid. In this case, based on information such as the collision location and the distribution of hazardous components, the hoisting path planning is adjusted (e.g., changing the lifting point, adjusting the movement trajectory, splitting the hoisting steps, etc.). After the adjustment is completed, the corresponding steps are returned to, and the hoisting process simulation and steel structure stress analysis are repeated until a valid path that meets the requirements is obtained. Then, the corresponding equipment installation plan and structural safety verification report are generated.

[0038] This embodiment presents a BIM-based heavy lifting equipment simulation method. By acquiring the architectural design parameters and electromechanical system requirement parameters of the steel structure factory to be constructed, an integrated BIM model is built, including steel structure deformation parameters and electromechanical equipment load parameters. Within this model, the heavy equipment lifting path is simulated and the steel structure stress is analyzed. Based on the analysis results, an equipment installation plan and a structural safety verification report are generated. Furthermore, the layout of electromechanical pipelines can be optimized, and a dynamic construction management platform can be built. This application achieves digital and precise simulation of heavy equipment lifting in tall steel structure factory buildings, proactively avoiding collisions and structural safety risks, improving the efficiency, accuracy, and safety of lifting construction, and enabling dynamic control of construction progress. It effectively solves the problems of poor coordination, high safety risks, and difficulty in guaranteeing the construction period in traditional lifting construction.

[0039] In some embodiments, a multi-objective optimization model can be established in the integrated BIM model, which simultaneously considers installation process requirements, structural load distribution, and steel structure deflection; an optimization algorithm is run based on the multi-objective optimization model to optimize the spatial arrangement of electromechanical pipelines and generate an optimized pipeline layout scheme.

[0040] Specifically, firstly, a multi-objective optimization model can be established: this model is guided by the actual construction needs of tall steel structure workshops, and at the same time takes installation process requirements (such as the accessibility of pipeline installation and the requirements for reserved maintenance passages), structural load distribution (such as the influence of pipeline weight on the stress of steel structure nodes), and steel structure deflection (such as the influence of easily deformable areas on pipeline installation accuracy) as core optimization objectives, so as to avoid the problem of insufficient construction feasibility caused by single-objective optimization.

[0041] Secondly, optimization algorithms can be run to optimize pipeline layout: data such as steel structure deformation parameters, electromechanical pipeline specifications, and equipment locations in the integrated BIM model are used as input to the algorithm. Through iterative calculation, the three-dimensional orientation, installation height, and support and hanger placement of the electromechanical pipelines are dynamically adjusted. Under the premise of meeting the constraints of each optimization objective, the algorithm achieves a comprehensive optimization effect that optimizes the total pipeline length, minimizes the risk of collision with the steel structure and equipment, and maximizes maintenance convenience. Finally, the optimized pipeline layout scheme is generated and updated synchronously in the integrated BIM model, providing a more reasonable spatial environment for the aforementioned hoisting path planning.

[0042] In some embodiments, an optimization algorithm is run based on the multi-objective optimization model to optimize the spatial arrangement of electromechanical pipelines and generate an optimized pipeline layout scheme, including: The optimization algorithm in the multi-objective optimization model is run to iteratively calculate the pipeline path and obtain the iterative calculation results; wherein, the optimization algorithm simultaneously aims to minimize the total pipeline length, maximize the avoidance of steel structure deflection sensitive areas, and meet the maintenance access requirements. Based on the iterative calculation results, the three-dimensional coordinates and orientation of electromechanical pipelines are automatically adjusted in the integrated BIM model to generate a pipeline layout scheme that meets all optimization objectives.

[0043] Specifically, firstly, the core objectives of the optimization algorithm are clearly defined: minimizing the total pipeline length (reducing material costs and construction difficulty), maximizing the avoidance of steel structure deflection-sensitive areas (avoiding pipeline damage due to structural deformation from stretching or compression), and meeting maintenance access requirements (reserving sufficient space for personnel and equipment maintenance) are the three core optimization objectives, ensuring that the optimization scheme takes into account economy, safety, and practicality.

[0044] Secondly, iterative calculations of pipeline routes are performed: the optimization algorithm is based on data in the integrated BIM model and adjusts the initial routes of electromechanical pipelines multiple times. In each iteration, the degree to which the three optimization objectives are met is evaluated. For example, in the first iteration, the pipeline route is adjusted to avoid deflection-sensitive areas; in the second iteration, the pipeline length is optimized to reduce material loss; and in the third iteration, the pipeline position is fine-tuned to reserve maintenance access. Through multiple iterations, a balanced optimization of each objective is achieved, and finally, an iterative calculation result that takes into account all optimization objectives is obtained.

[0045] Finally, an optimized solution is automatically generated: based on the iterative calculation results, the three-dimensional coordinates, directions, and support positions of the electromechanical pipelines are automatically updated in the integrated BIM model to ensure that the pipeline layout is consistent with the optimization results; the generated pipeline layout solution can be directly used to guide construction and is simultaneously synchronized to the hoisting simulation module to provide accurate spatial constraints for the hoisting path planning of heavy equipment.

[0046] In some embodiments, the integrated BIM model can be associated with the construction schedule to build a dynamic construction management and control platform; through the dynamic construction management and control platform, based on the construction progress data collected on site, the comparison between the actual construction progress and the BIM model can be visualized; when there is a deviation between the actual construction progress and the preset nodes of the BIM model, progress warning information is generated.

[0047] Specifically, a dynamic construction management and control platform can be built: the integrated BIM model is linked with the construction schedule (including the time nodes, task breakdown, resource allocation, etc. of hoisting construction and related electromechanical installation procedures), and the correspondence between BIM model components, construction tasks, and time nodes is established, forming a dynamic construction management and control platform that integrates model visualization, progress management, and data collection.

[0048] Next, a visual comparison of construction progress is conducted: actual construction progress data (such as the completion status of hoisting procedures, equipment installation progress, personnel and equipment input, etc.) is collected through mobile devices, on-site sensors, etc., and uploaded to the dynamic construction management and control platform in real time; the platform compares the actual construction progress with the preset progress nodes in the BIM model, and intuitively presents whether the progress of each process meets the planned requirements through visualization methods such as color marking and progress bar display.

[0049] Then, progress warning information is generated: The platform monitors the deviation between the actual construction progress and the preset nodes in real time. When the deviation value exceeds the preset threshold (such as the progress being delayed by more than 2 days), progress warning information is automatically generated. The warning information includes the name of the delayed process, the degree of deviation, the affected subsequent processes, and suggested adjustment measures, and is pushed to relevant management personnel. Management personnel can adjust the construction plan and allocate resources in a timely manner based on the warning information to ensure that the construction period is not affected.
