Description

Technical Field

[0001] The invention relates to the field of film enclosure system production equipment, and in particular to a laser dotting and scribing device for a film enclosure system. Background Art

[0002] The membrane enclosure system is a core component in the fields of liquefied natural gas (LNG) storage tanks, ship cargo tanks, etc. Its main function is to ensure the safe storage and transportation of LNG in extremely low temperature (-162°C) environments through the combination of multi-layer membrane shielding layers and insulation modules. The construction accuracy of the membrane enclosure system directly affects the sealing, insulation performance and overall safety of the system, so the construction process is extremely demanding.

[0003] During the construction of the membrane enclosure system, dotting and marking is a crucial step. The main purpose of dotting and marking is to accurately mark the installation positions of the insulation module and the membrane shielding layer on the inner wall of the tank to ensure the alignment and fixation of each layer structure. The traditional dotting and marking method mainly relies on manual operation, using manual measuring tools (such as tape measures, levels, etc.) for marking. However, this method has the following problems: Insufficient precision: Manual measurement and marking are easily affected by factors such as the operator's technical level and visual errors, making it difficult to ensure the accuracy of dotting and marking. Especially in large LNG storage tanks, the geometric shape of the inner wall of the tank is complex, and the error of manual dotting and marking will be further magnified, affecting the subsequent construction quality.

[0004] Low efficiency: Manual marking takes a lot of time and manpower, especially in large-scale storage tank projects. The construction period is long and it is difficult to meet the high efficiency requirements of modern engineering.

[0005] Poor consistency: Due to the uncontrollability of manual operation, there may be inconsistencies in the dotting and dashing of different areas, resulting in deviations in the installation positions of the insulation modules and the film shielding layer, affecting the overall performance of the system.

[0006] Safety issues: Manual operation requires high-altitude work inside the tank, which poses certain safety risks, especially in confined spaces and complex environments, where the safety of operators is difficult to guarantee. Summary of the invention

[0021] 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.

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Reference Figures 1 to 5 As shown, this embodiment provides a laser dotting and marking device for a film enclosure system, including a base shell 1, a multi-stage lifting mechanism is installed on the top surface of the base shell 1, an image collector 8 is rotatably connected to the top surface of the multi-stage lifting mechanism, a laser dotting device 9 is installed on the image collector 8, a plurality of self-propelled wheels 13 are installed on the bottom surface of the base shell 1, and a position adjustment mechanism is installed on the base shell 1 to cooperate with the self-propelled wheels 13 to adjust the position of the device.

[0024] The present invention is directed to a film enclosure system for tank bodies. Since tank bodies are usually large in size, the safety of operators cannot be effectively guaranteed when manual dotting and marking are usually at a high height. The present invention first reduces the size of the entire device by setting a multi-stage lifting mechanism, which is more convenient in the actual transportation of the device. When the device needs to be aligned with the center, the position of the device can be adjusted by the position adjustment mechanism in conjunction with the self-propelled wheels 13. This arrangement can ensure that the image collector 8 is located in the most suitable position for image modeling, and cooperates with the laser dotting device 9 to complete the marking and dotting operations, reducing the intervention of manual operations and greatly ensuring the safety of the operators.

[0025] A further optimized solution is that the multi-stage lifting mechanism includes a bottom plate 2 fixedly connected to the top surface of the base shell 1, a first sleeve 3 fixedly connected to the top surface of the bottom plate 2, a second sleeve 4 vertically slidably connected in the first sleeve 3, a third sleeve 5 slidably connected in the second sleeve 4, a fourth sleeve 6 slidably connected in the third sleeve 5, an image collector 8 is installed on the top surface of the fourth sleeve 6, a lifting drive component is transmission-connected between the first sleeve 3, the second sleeve 4, the third sleeve 5, and the fourth sleeve 6, and the lifting drive component is installed on the bottom plate 2.

[0026] By controlling the operation of the lifting drive component, the lifting drive component can simultaneously drive the first sleeve 3, the second sleeve 4, the third sleeve 5, and the fourth sleeve 6 to extend or contract, which can then drive the image collector 8 and the laser dotting device 9 to move up and down, ensuring smooth completion of scanning and dotting operations in higher spaces.

[0027] Further optimizing the scheme, the inner wall of the first sleeve 3 is provided with a first vertical groove 301, the outer wall of the second sleeve 4 is fixedly connected with the second sleeve key 401, and the first vertical groove 301 and the second sleeve key 401 are vertically slidably matched; A second sleeve groove 402 is formed on the inner wall of the second sleeve 4, a third sleeve key 501 is fixedly connected to the outer side of the third sleeve 5, and the second sleeve groove 402 and the third sleeve key 501 are slidably matched; A third sleeve groove 502 is formed on the inner wall of the third sleeve 5 , and a fourth sleeve key 601 is fixedly connected to the outer side of the fourth sleeve 6 . The third sleeve groove 502 and the fourth sleeve key 601 are vertically slidably matched.

[0028] The cooperation between the first vertical groove 301 and the second sleeve key 401, the second sleeve groove 402 and the third sleeve key 501, and the third sleeve groove 502 and the fourth sleeve key 601 can ensure that the first sleeve 3, the second sleeve 4, the third sleeve 5, and the fourth sleeve 6 will not rotate relative to each other during the extension and retraction process.

[0029] According to a further optimized solution, the lifting drive component includes a first drive component for driving the second sleeve 4 to be lifted and lowered, a second drive component for driving the third sleeve 5 to be lifted and lowered, and a third drive component for driving the fourth sleeve 6 to be lifted and lowered. The first drive component is transmission-connected to the second sleeve 4, the second drive component is transmission-connected to the third sleeve 5, and the third drive component is transmission-connected to the fourth sleeve 6.

[0030] Further optimized solution, the first driving component includes a first screw 10 rotatably connected to the bottom plate 2, a first external thread 1001 is provided on the outside of the first screw 10, the bottom end of the first screw 10 passes through the bottom plate 2 and is meshed with a lifting gear 104, the lifting gear 104 is axially connected to a lifting motor 103, and the lifting motor 103 is installed inside the base shell 1 through a mounting plate 102; the first external thread 1001 is matched with the bottom thread of the second sleeve 4; The second driving component includes a second screw rod 11 rotatably connected to the bottom surface of the first sleeve 3, a second external thread 1101 is provided on the outer side of the second screw rod 11, the first screw rod 10 is movably inserted into the second screw rod 11, the first screw rod 10 and the second screw rod 11 are limitedly vertically slidably matched, and the second external thread 1101 is matched with the bottom thread of the third sleeve 5.

[0031] The third driving component includes a third screw 12 rotatably connected to the bottom surface of the second sleeve 4, a third external thread 1201 is provided on the outer side of the third screw 12, the second screw 11 is movably inserted into the third screw 12, the second screw 11 and the third screw 12 are limitedly vertically slidably matched, and the third external thread 1201 is matched with the bottom wall thread of the fourth sleeve 6.

[0032] By controlling the operation of the lifting motor 103, the lifting motor 103 can drive the first screw 10 to rotate, and the first sleeve 3, the second sleeve 4, the third sleeve 5, and the fourth sleeve 6 are vertically slidably matched, and the first screw 10, the second screw 11, and the third screw 12 are vertically slidably matched. In this way, when the first screw 10 rotates, it will drive the second screw 11 and the third screw 12 to rotate. In this way, the first screw 10 will push the second sleeve 4 to move, the second screw 11 will push the third sleeve 5 to move, and the third screw 12 will push the fourth sleeve 6 to move. In this way, multi-stage movement can be achieved, and the lifting motor 103 drives the first screw 10 in a rotary drive, and the screws are prevented by threaded matching. Compared with the linear drive telescopic method, this driving method greatly reduces the force consumption and can further save energy consumption.

[0033] According to a further optimized solution, a first screw groove 1002 is fixedly connected to the outer side of the first screw 10, and a second screw groove 1102 is opened on the inner wall of the second screw 11, and the first screw groove 1002 and the second screw groove 1102 are vertically slidably matched; A second screw key 1103 is fixedly connected to the outer side of the second external thread 1101 , a third screw groove 1202 is formed on the inner wall of the third screw 12 , and the second screw key 1103 and the third screw groove 1202 are vertically slidably matched.

[0034] A further optimized solution is that the position adjustment mechanism includes a partition 101 fixedly connected to the inside of the base shell 1, and a rotation drive motor 110 is fixedly connected to the bottom surface of the partition 101. The rotation drive motor 110 is connected to a rotation drive gear 109, and the rotation drive gear 109 is meshed with a rotation gear 108. The rotation gear 108 is rotatably connected to the bottom surface of the base shell 1, and the center of the rotation gear 108 is slidably connected to a telescopic shaft 106 through a spline. The bottom end of the telescopic shaft 106 extends out of the base shell 1 and is fixedly connected to a rotation support plate 107, and the top end of the telescopic shaft 106 is fixedly connected to the output shaft of the telescopic motor 105, and the telescopic motor 105 is rotatably connected to the bottom surface of the base shell 1.

[0035] A turntable motor 701 is fixedly connected to the top surface of the fourth sleeve 6. The turntable motor 701 is vertically arranged. The output shaft of the turntable motor 701 is connected to a turntable 7. The image collector 8 is installed on the turntable 7. After the entire device is placed into the tank body, the turntable 7 is controlled to rotate first. The reflected signal emitted and received by the laser 802 can be used to determine whether the device is located at the center of the tank body. When it is not at the center, the telescopic motor 105 is controlled to extend according to the detected offset, so that the rotating support plate 107 supports the bottom, so that the self-propelled wheel 13 is separated from the support, and then the rotary drive motor 110 is controlled to rotate. The rotary drive motor 110 drives the rotary drive gear 109 to rotate, and the rotary drive gear 109 drives the rotary gear 108 to rotate. The rotary gear 108 will drive the rotary The rotating support plate 107 rotates. Since the telescopic motor 105 and the base shell 1 are connected in a rotating manner, the entire device will rotate a certain angle at this time. The rotation angle can be adjusted according to the offset detected by the laser 802, and then the telescopic motor 105 is retracted and supported by the self-propelled wheels 13. The self-propelled wheels 13 are controlled to move a suitable distance so that the entire device is located at the center of the detection. At this time, the image collector 8 is driven to realize a 360° scan of the inner wall of the tank by controlling the rotation of the turntable motor 701, and the scanning of the inner wall of the tank at different heights can be realized in conjunction with the multi-stage lifting mechanism. After the scanning is completed, the inner wall of the tank can be modeled, and then the corresponding components can be controlled to operate, and the laser dotting device 9 can be used to realize dotting and marking inside the tank.

[0036] According to a further optimization scheme, the image collector 8 includes a body, on which two cameras 801 and a laser 802 are mounted, the two cameras 801 are distributed on both sides of the laser 802, and the two cameras 801 are arranged at an angle.

[0037] By setting two cameras 801 and superimposing the images of the two cameras, surface recognition in the three-dimensional depth direction can be achieved. Specifically, an ATOS Triple Scan scanner can be used to implement the operation of the present invention.

[0038] In this embodiment, the ATOS Triple Scan scanner cooperates with the laser 802 and the laser dotting device 9 to realize the detection through self-learning, as follows: Adaptive surface reconstruction first preprocesses the collected 3D point cloud data and uses an outlier filtering method based on statistical principles. The specific steps are: calculate the average distance between each point and its 50 nearest neighboring points, set 1.0 times the standard deviation as the threshold, and filter out abnormal points that exceed the threshold; Then, the improved PointNet++ network is used to extract point cloud features. The network learns local geometric features through a multi-layer perceptron and obtains global features through a maximum pooling layer. Finally, the improved Poisson reconstruction algorithm is used to transform the discrete point cloud into a continuous surface model through octree hierarchical processing and gradient field calculation. Dynamic error compensation uses a two-layer LSTM network structure to process time series environmental data. The network input is time series data containing 10-dimensional features such as temperature, humidity, and vibration, and the time step is set to 10. The first layer of LSTM contains 64 units and returns the complete sequence. The second layer of LSTM also has 64 units but only returns the final state. Then, through a fully connected layer of 32 nodes, the error prediction values ​​in the three directions of XYZ are finally output; The model training uses the Huber loss function and AdamW optimizer, the initial learning rate is set to 0.001 and adjusted using the cosine annealing strategy.

[0039] Data processing,The data flow goes through the following processing stages in sequence: Downsampling: The original point cloud is uniformly sampled using a 0.5mm voxel grid; Denoising: Combining statistical outlier removal and radius filtering to denoise the scanned data; Feature extraction: extract local geometric features through 3D convolution kernel; Surface reconstruction: construct watertight triangular mesh based on Poisson's equation; Deviation analysis: ICP registration of the reconstructed surface with the design model; Path planning: Path planning is performed taking into account surface curvature and material properties; After self-learning, the device can ensure the accuracy of marking and dotting during the process.
