Description

Technical Field

[0001] The invention relates to the technical field of glass furnace construction, and in particular to a method for installing a sliding support steel beam in a photovoltaic glass all-oxygen furnace. Background Art

[0002] Sliding support steel beam refers to a structural form in which sliding supports are used to connect the steel beam and the support. The sliding support is usually composed of a steel slider and a slide plate, which allows the steel beam to produce horizontal displacement under load while maintaining connection with the support.

[0003] As the country vigorously develops new energy, the construction of photovoltaic glass production lines is increasing. In the process of building glass kilns, due to the complexity of the production process and the high precision of equipment installation, the relevant construction process is relatively complicated. The glass kiln needs to withstand high temperatures during the production process, and the temperature will cause the material to expand and contract. If the fixed support is a rigid connection, the steel beam will be overstressed or even cracked. The use of sliding supports can allow the steel beam to produce a certain horizontal displacement when the temperature changes, reducing the impact of the force and protecting the safety of the steel beam.

[0004] Since the sliding bearing steel beam is a sliding connection, the position of the bearing must be installed accurately, otherwise deviation will cause the bearing to fail to slide normally. At the same time, although the sliding bearing needs to be able to slide in the horizontal direction, it needs to be firmly fixed in the structure in the vertical direction to ensure that the bearing and steel beam are installed and fixed firmly and reliably. However, the supervision at the construction site, especially the front-line construction site, is not strong enough, and the construction personnel do not have enough control over the accuracy. Summary of the invention

[0005] The purpose of the present invention is to provide a method for installing a sliding support steel beam in a photovoltaic glass all-oxygen kiln, which has the advantages of accurate installation of the sliding support steel beam without deviation, and higher efficiency of real-time synchronization of the installation and construction monitoring of the sliding support steel beam, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides the following technical solution: a method for installing a sliding support steel beam in a photovoltaic glass all-oxygen kiln, comprising the following steps:

[0007] Step 1: Scanning and modeling preparation: prepare the scanner and modeling software, survey the support installation location and surrounding environment in advance, and clean the surrounding environment in time;

[0008] Step 2: Real-time scanning of the site: The real-time data of the site ground is transmitted to the modeling software to generate a real-time 3D model. The geometric information and flatness of the ground are obtained through real-time scanning and combined with the support installation position;

[0009] Step 3: Combine the real-time generated three-dimensional ground model with the model of the support installation position to verify and adjust the flatness of the support installation ground and the matching of the support position;

[0010] Step 4: Update the ground part of the installation reference model according to the real-time generated ground model data to make the ground model consistent with the actual site conditions;

[0011] Step 5: Pre-process the ground at the support installation location according to the data requirements of the ground model and the installation reference model;

[0012] Step 6. After the ground pretreatment is completed, carry out the actual installation of the support according to the updated installation reference model guidance.

[0013] Preferably, the step 1 further comprises the following detailed steps:

[0014] S1.1. Start the modeling software and connect it to the scanner to survey the support installation location and surrounding environment:

[0015] S1.2. Use a scanner to conduct a comprehensive scan around the support installation location, covering all construction areas;

[0016] S1.3. Before scanning, clean the support installation location and surrounding environment to ensure that there are no obstructions or interferences that may affect the accuracy of the scan.

[0017] Preferably, the modeling software for generating the three-dimensional model of the site is one of AutoCAD, Rhino, SketchUp or Revit, and the modeling software processes and edits the imported scan data to eliminate noise, fill in missing parts, and adjust data accuracy.

[0018] Preferably, the step 2 further comprises the following detailed steps:

[0020] S2.2. Use the scanner to start the real-time scanning program, quickly move the scanner on the ground of the site, obtain ground data in real time, and transmit the ground data obtained by the real-time scanning to the modeling software by wireless or wired means;

[0021] S2.3, the modeling software processes the received ground data in real time, generates a real-time three-dimensional model, reflects the geometric information and flatness of the site ground, analyzes the real-time generated three-dimensional model, and extracts the geometric information of the ground, including elevation, slope, contour, etc. and flatness data;

[0022] S2.4. Combine the real-time generated three-dimensional model with the information of the support installation position to ensure that the support installation position matches and is stable with the site ground.

[0023] Preferably, the three-dimensional ground model generated in real time in step three is adjusted if it is inconsistent with the actual ground during construction, and the underlying logic of the adjustment operation is: if the error degree is ≥ 3% of the total construction area, the site is scanned twice in real time in the area where the error occurs, and the scanning range is the error area + 50%. The scanning range increases by 3% for every 1% increase in the error area.

[0024] Preferably, the expression of the adjustment operation in step 3 is:

[0025] Adjustment operation conditions: If E ≥ 0.03A, then perform the adjustment operation.

[0026] Scanning range calculation: S-X+0.5X, i.e. S-1.5X;

[0027] Error area growth: For every 1% increase in error area, the scanning range increases by 3%;

[0028] S-(1+0.03n)X

[0029] Where the error degree is E, the total construction area is A, the error area is X, the scanning range is S, and n is the percentage of the error area increase.

[0030] Preferably, the underlying logic of the matching of the support position is: the support installation position in step two is the absolute value jd, and if the actual installation position sj of the support deviates from the absolute value jd, it shall obey the absolute value jd; if the actual installation position sj is higher than the absolute value jd, the height difference g shall be subtracted; if the actual installation position sj is lower than the absolute value jd, the height difference g shall be added.

[0031] Preferably, the matching formula of the support position is:

[0032] sj=jd-sggn(Δ)·g

[0033] Wherein, sgn(Δ) is a sign function, which is 1 when Δ>0, -1 when Δ<0, and 0 when Δ=0. Preferably, the step five further includes the following detailed steps:

[0034] S5.1. Ensure that relevant data on the support installation location is obtained, including the actual position coordinates of the support and the height difference with the ground;

[0036] S5.3. Match and align the imported ground model and the installation reference model to ensure that they are in the same coordinate system and accurately correspond to the support installation position. If they are not in the same coordinate system, return to step three.

[0037] Preferably, the step six also includes the following detailed steps:

[0038] S6.1. Ensure that the bolts, nuts and support base required for support installation are ready, and set the installation position according to the updated installation reference model:

[0042] Compared with the prior art, the present invention has the following beneficial effects:

[0043] 1. The present invention uses a scanner to perform a comprehensive scan around the support installation position, and generates a three-dimensional model in real time to reflect the geometric information and flatness of the ground. The imported scan data is processed and edited with the help of modeling software to eliminate noise, fill in missing parts, and adjust data accuracy. The generated ground model is accurate, and real-time scanning parameters are set to meet scanning requirements, scan area, density, and speed to ensure the accuracy of real-time acquisition of ground data. The real-time generated ground model is combined with the model of the support installation position for verification and adjustment to ensure the flatness and position matching of the support installation ground, detect the error area, and perform a secondary scan when the error reaches a certain threshold, gradually expand the scanning range, ensure the accuracy of the adjustment, and make adjustments based on the deviation between the absolute value and the actual installation position to ensure that the installation position of the support is accurate, thereby achieving the beneficial effect of accurately installing the sliding support steel beam position without deviation.

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] See also Figure 1 , a method for installing a sliding support steel beam in a photovoltaic glass all-oxygen kiln, comprising the following steps:

[0048] Step 1: Scanning and modeling preparation: prepare the scanner and modeling software, survey the support installation location and surrounding environment in advance, and clean the surrounding environment in time;

[0049] Step 2: Real-time scanning of the site: The real-time data of the site ground is transmitted to the modeling software to generate a real-time 3D model. The geometric information and flatness of the ground are obtained through real-time scanning and combined with the support installation position;

[0050] Step 3: Combine the real-time generated three-dimensional ground model with the model of the support installation position to verify and adjust the flatness of the support installation ground and the matching of the support position;

[0051] Step 4: Update the ground part of the installation reference model according to the real-time generated ground model data to make the ground model consistent with the actual site conditions;

[0052] Step 5: Pre-process the ground at the support installation location according to the data requirements of the ground model and the installation reference model;

[0053] Step 6. After the ground pretreatment is completed, carry out the actual installation of the support according to the updated installation reference model guidance.

[0054] Specifically, step one also includes the following detailed steps:

[0055] S1.1. Start the modeling software and connect it to the scanner to survey the support installation location and surrounding environment:

[0056] S1.2. Use a scanner to conduct a comprehensive scan around the support installation location, covering all construction areas;

[0057] S1.3. Before scanning, clean the support installation location and surrounding environment to ensure that there are no obstructions or interferences that may affect the accuracy of the scan.

[0058] By surveying the support installation location and the surrounding environment, clearing obstructions or interferences, and ensuring that the scanner can accurately capture ground information, the accuracy and reliability of data collection are improved. The scanner is used to conduct a comprehensive scan around the support installation location, covering all construction areas, ensuring that sufficiently complete ground data is obtained, avoiding the omission of important information, and facilitating subsequent modeling and position adjustment. Cleaning the support installation location and the surrounding environment reduces interference and errors during the scanning process, speeds up the scanning process, and improves the efficiency and real-time nature of data collection at the construction site. Clearing obstructions or interferences in the construction area reduces safety risks during the construction process, ensures the safety of construction personnel and equipment, and improves the overall safety of the construction site.

[0059] Specifically, the modeling software for generating the three-dimensional model of the site is one of AutoCAD, Rhino, SketchUp or Revit. The modeling software processes and edits the imported scan data to eliminate noise, fill in missing parts, and adjust data accuracy.

[0060] The modeling software has powerful data processing and editing functions, which can process and edit the imported scan data, including eliminating noise, filling in missing parts, adjusting data accuracy, etc., to improve the quality and accuracy of the data.

[0061] Specifically, step 2 also includes the following detailed steps:

[0062] S2.1. Set the real-time scanning parameters in the modeling software, including scanning area, scanning density and scanning speed, to meet the real-time scanning requirements;

[0063] S2.2. Use the scanner to start the real-time scanning program, quickly move the scanner on the ground of the site, obtain ground data in real time, and transmit the ground data obtained by the real-time scanning to the modeling software by wireless or wired means;

[0064] S2.3, the modeling software processes the received ground data in real time, generates a real-time three-dimensional model, reflects the geometric information and flatness of the site ground, analyzes the real-time generated three-dimensional model, and extracts the geometric information of the ground, including elevation, slope, contour, etc. and flatness data;

[0065] S2.4. Combine the real-time generated three-dimensional model with the information of the support installation position to ensure that the support installation position matches and is stable with the site ground.

[0066] Set the real-time scanning parameters in the modeling software, including the scanning area, scanning density and scanning speed, optimize the settings according to the specific needs of construction monitoring and site conditions, improve the efficiency and accuracy of the scan, analyze the real-time generated 3D model, extract the geometric information of the ground, including elevation, slope, contour, etc. and flatness data, provide detailed data support for construction monitoring, and enable construction personnel to adjust the construction plan in time. Combine the real-time generated 3D model with the information of the support installation position to ensure the matching and stability of the support installation position and the site ground, and improve the construction quality and safety.

[0067] Specifically, the three-dimensional ground model generated in real time in step three is adjusted if it is inconsistent with the actual ground during construction. The underlying logic of the adjustment operation is: if the error degree is ≥ 3% of the total construction area, the site is scanned twice in real time in the area where the error occurs, and the scanning range is the error area + 50%. For every 1% increase in the error area, the scanning range increases by 3%.

[0068] Specifically, the expression of the adjustment operation in step 3 is:

[0069] Adjustment operation conditions: If E ≥ 0.03A, then perform the adjustment operation.

[0070] Scanning range calculation: S-X+0.5X, i.e. S-1.5X;

[0071] Error area growth: For every 1% increase in error area, the scanning range increases by 3%;

[0072] S-(1+0.03n)X

[0073] Where the error degree is E, the total construction area is A, the error area is X, the scanning range is S, and n is the percentage of the error area increase.

[0074] Automatic adjustment is performed when the real-time generated 3D ground model is inconsistent with the actual ground during construction. By setting the error threshold, once the error reaches or exceeds 3% of the total construction area, the adjustment operation is initiated. The current error area is calculated and the scanning range is expanded to the error area + 50% to ensure that the area where the error may exist is covered. As the error area grows, the scanning range is also expanded accordingly. The scanning range is dynamically adjusted according to the error situation to more accurately adjust the real-time generated 3D ground model to ensure that it is consistent with the actual ground.

[0075] Specifically, the underlying logic of the matching of the support position is: in step two, the support installation position is the absolute value jd. If there is a deviation between the actual installation position sj of the support and the absolute value jd, the absolute value jd shall be obeyed. If the actual installation position sj is higher than the absolute value jd, the height difference g shall be subtracted. If the actual installation position sj is lower than the absolute value jd, the height difference g shall be added.

[0076] Specifically, the matching formula of the support position is:

[0077] sj=jd-sgn(Δ)·g

[0078] Wherein, sgn(Δ) is a sign function, which is 1 when Δ>0, -1 when Δ<0, and 0 when Δ=0. Specifically, step five also includes the following detailed steps:

[0079] S5.1. Ensure that relevant data on the support installation location is obtained, including the actual position coordinates of the support and the height difference with the ground;

[0080] S5.2. Import the real-time generated ground model data and support installation reference model data into the modeling software;

[0081] S5.3. Match and align the imported ground model and the installation reference model to ensure that they are in the same coordinate system and accurately correspond to the support installation position. If they are not in the same coordinate system, return to step three.

[0082] Specifically, step six also includes the following detailed steps:

[0083] S6.1. Ensure that the bolts, nuts and support base required for support installation are ready, and set the installation position according to the updated installation reference model:

[0084] S6.2. Determine the exact installation position and orientation of the support according to the updated installation reference model guidance, and use a marking tool to mark the installation position of the support on the ground;

[0085] S6.3. Drill holes at the marked locations according to the design requirements of the support base for installing bolts to fix the support;

[0086] S6.4. Place the support base at the drilled hole, ensure that the support base fits tightly against the ground, and then fix the support to the ground with bolts and nuts.

[0087] The present invention and its embodiments are described schematically above, and the description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by it and designs a structural method and an embodiment similar to the technical solution without creativity without departing from the purpose of the invention, they shall all fall within the protection scope of the present invention.
