Description

Technical Field

[0001] The present invention belongs to the technical field of application of BIM technology to large coke oven body masonry technology, and specifically relates to a large coke oven overall flat masonry method based on BIM technology. Background Art

[0002] Large coke ovens generally refer to top-loading coke ovens over 7 meters tall and rammed coke ovens over 5.5 meters tall. The coke oven body primarily consists of the roof area, carbonization and combustion chambers, inclined flues, and regenerators. Its structure is complex, and the quality of its construction directly impacts the coke oven's production performance after commissioning. A single large coke oven body uses over 10 types of refractory materials and over 1,000 different brick types, weighing approximately 30,000 tons. The construction process is complex and the workload is enormous. Traditional coke oven body construction utilizes a staggered-layer construction method controlled by burner heads. By constructing each burner head first, the accuracy of the coke oven wall is controlled. Using this traditional method for large coke oven construction makes it difficult to effectively control the overall accuracy and quality of the body. Summary of the Invention

[0003] The purpose of the present invention is to provide a large-scale coke oven overall leveling masonry method based on BIM technology. Based on BIM technology and combined with the furnace body leveling masonry method, the construction quality of the refractory brick masonry structure in the furnace is controlled, solving the furnace construction problems caused by traditional masonry furnaces, such as poor overall precision control of large coke oven bodies, great difficulty in staggered masonry technology, and low efficiency. Through BIM three-dimensional digital technology, an integrated data model is created for furnace body masonry professional information. By utilizing the advantages of model space visualization communication, dynamic simulation and inspection of the masonry process, data analysis, collaboration, and management, combined with the innovative large-scale coke oven furnace body leveling masonry process, a standardized, intensive, and factory-based construction production method is formed, which improves the efficiency and quality of large-scale coke oven furnace body masonry construction.

[0021] Beneficial effects of the present invention:

[0022] 1. Use the BIM three-dimensional model to simulate the masonry of the furnace body. Utilize spatial visualization technology to convert the two-dimensional complex masonry structure design drawings of large coke oven bodies into three-dimensional space simulation. This allows for specification review, inspection of refractory brick matching and furnace body pores before construction, and optimization and correction of design errors, thus avoiding errors in later construction.

[0023] 2. Through the cloud platform, model reviewers and professional furnace construction engineers can check the on-site construction operability of refractory brick configuration and masonry, effectively controlling the construction quality of the furnace masonry structure. The cloud platform also centrally and intelligently manages the coke oven's massive amount of refractory brick masonry information, providing support during the refractory brick customization, procurement, and masonry stages, improving refractory brick utilization, reducing losses, and lowering project costs.

[0024] 3. The adoption of the overall flat-layer masonry process for the coke oven body solves the problem of precision control in the traditional staggered-layer masonry process, and also provides a strong fit for the application of BIM technology. The BIM three-dimensional model can be used to encode, configure, and count the refractory bricks laid layer by layer in various parts of the furnace body to guide the masonry construction. After each layer is laid, the masonry process is corrected in real time by comparing the three-dimensional model through spatial three-dimensional scanning, which promotes the development of coke oven masonry methods towards high precision, digitization, and intelligence.

[0025] 4. The BIM-based, integrated, flat-bed masonry method for large coke ovens improves upon traditional coke oven construction methods, creating a visual, intensive, and factory-based masonry production method. This significantly reduces the technical difficulty of coke oven construction, maximizes furnace body masonry accuracy, quality, and efficiency, reduces rework rates, and extends the life of the coke ovens. The accuracy of furnace body refractory bricks is controlled within ±2mm, and the masonry qualification rate has increased to over 98%.

DETAILED DESCRIPTION

[0027] The following non-limiting examples illustrate the present invention.

[0028] Example 1:

[0029] A large coke oven integral leveling masonry method based on BIM technology includes the following steps:

[0030] Step S001: Using BIM modeling software, various refractory bricks are constructed to create an initial model of the coke oven body. Using BIM modeling software, a 3D model of the various refractory bricks is created based on the coke oven body masonry design drawings. Simulating 3D flat masonry of the body is performed according to the furnace body masonry specifications and parameters. A preliminary inspection of each part of the 3D masonry model is performed layer by layer, and design optimization and modification are performed to address issues such as non-compliance with specifications, improper refractory brick placement, spatial collisions of refractory bricks, and blocked furnace body holes.

[0031] Step S002: Based on the overall flat masonry process, the furnace model undergoes a professional secondary review. The furnace model, which passes the initial inspection, is uploaded to the cloud platform. A professional model reviewer will first review the configuration and placement of the refractory bricks. After the review is complete, the model on the cloud platform is made accessible to professional furnace builders, who then check the on-site operability of the configuration and placement of the refractory bricks to determine the final design and 3D model.

[0032] Step S003 opens the refractory brick masonry model data to support the overall flat masonry construction and management of the furnace body. After all inspections and reviews are completed, the final model is numbered in the BIM software by refractory bricks according to the number of layers and their location within the furnace wall. The total number of refractory bricks of each type, as well as the model, quantity, and number of refractory bricks for each layer in each part of the furnace body, are derived. This information is then uploaded to the cloud platform and made available to professional engineers and on-site masonry personnel for refractory brick customization, procurement, and masonry process management.

[0033] Step S004: Arrange control points before construction. Before the coke oven body is laid, precision control points for the coke oven body's leveling are designed and arranged based on site conditions. These control points should effectively measure and control the overall and detailed construction process, ensuring accuracy and quality.

[0034] Step S005: The entire coke oven body is leveled and laid on-site, combining the model data. Based on the brick type, quantity, and numbering information for each layer of refractory bricks in the cloud platform, the refractory bricks for that layer are inspected, configured, and numbered. Before each layer is laid, visual instructions are provided to the builders based on the BIM 3D masonry model. After these instructions, the entire coke oven body is leveled and laid, based on precision control points and the brick type, configuration, and numbering information from the BIM 3D model.

[0035] Step S006: Use spatial scanning technology combined with the BIM model to review and accept the results of each layer of refractory brick masonry. After each layer of the furnace body is completed, the masonry results are promptly inspected and reviewed using spatial 3D scanning technology. If 3D scanning technology is not available, the masonry results can be reviewed and inspected based on precision control points. The spatial information of the furnace body masonry is scanned and collected, and compared with the established BIM 3D model. The masonry results are corrected in real time to ensure masonry accuracy and quality.

[0036] Step S007: After each layer is inspected and accepted, the next layer is laid until the furnace body is completed.

[0037] The aforementioned basic examples and their further alternatives can be freely combined to form multiple embodiments, all of which are applicable and claimed embodiments of the present invention. In the scheme of the present invention, each alternative can be arbitrarily combined with any other basic examples and alternatives.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
