Description

Technical Field

[0001] This invention relates to the field of cantilevered aerial platform lifting, specifically a method for hydraulically lifting a cantilevered aerial platform with the assistance of a drone. Background Technology

[0002] The use of cantilever structures in architectural design gives buildings a unique appearance and provides more creative space. Furthermore, cantilever structures also meet space utilization and functional requirements. In terms of technological challenges and engineering innovation, addressing issues such as high-altitude assembly and structural stability related to cantilever structures has driven technological development in the architectural field. The application of cantilevered aerial platforms not only reflects technological innovation in architecture but also satisfies multiple pursuits of functionality and aesthetics.

[0003] Traditional methods for installing cantilevered aerial platforms mainly involve high-altitude assembly and welding. This method presents numerous problems, such as high construction difficulty, enormous workload, and high quality risks. High-altitude assembly requires precise manual operation and complex hoisting equipment, posing significant operational risks. During welding, the instability of the high-altitude environment greatly affects both welding quality and efficiency.

[0004] The aforementioned problems can be solved by assembling and welding a cantilevered aerial platform at low altitude, then lifting it to a set height using a hydraulic synchronous lifting system to complete the installation. However, lifting a cantilevered aerial platform is a complex project, requiring precise control of the hydraulic synchronous lifting system and simultaneous monitoring of the platform's horizontal and longitudinal displacement to prevent tilting, shifting, or deformation. Traditional monitoring methods rely primarily on manual observation and measurement, which suffers from drawbacks such as large errors, low efficiency, and high risks. Summary of the Invention

[0005] The purpose of this invention is to provide a method for hydraulically lifting a cantilevered platform with the assistance of a drone. This method utilizes a high-resolution camera and multi-sensor system mounted on the drone to perform all-round real-time monitoring of the cantilevered platform, reducing human error in the monitoring process and making the monitoring results more accurate. Through a wirelessly connected control system, the horizontal and longitudinal displacements of the cantilevered platform are analyzed and calculated, and the hydraulic synchronous lifting system is dynamically adjusted according to the calculation results, thereby improving the safety and efficiency of lifting and reducing risks and losses during the lifting process.

[0006] The above-mentioned optimized structure of the present invention is achieved through the following technical solution: a method for hydraulically lifting a cantilevered aerial platform assisted by a drone, comprising a steel column, a hydraulic synchronous lifting system, and a cantilevered aerial platform, wherein the hydraulic synchronous lifting system can drive the cantilevered aerial platform to move in the vertical direction, and the cantilevered aerial platform is provided with a feature mark for auxiliary positioning.

[0007] It also includes drones, which are equipped with high-resolution cameras and multi-sensor systems. The high-resolution cameras and multi-sensor systems work together to enable all-round real-time monitoring of the cantilevered aerial platform. The drones are wirelessly connected to a control system.

[0008] The method for hydraulically lifting a cantilevered aerial platform with the assistance of drones includes the following steps:

[0009] Step S1: Install the hydraulic synchronous lifting system, assemble the cantilevered aerial platform, and arrange the auxiliary positioning feature marks at the corresponding measurement points on the cantilevered aerial platform;

[0010] Step S2: The cantilevered aerial platform is trial-lifted and loaded step by step according to the design load sequence until the cantilevered aerial platform is suspended in the air. The hydraulic synchronous lifting system is checked again for any abnormalities, and the measurement data is compared with that when it is off the ground. After confirming that there are no abnormalities, the formal lifting is prepared.

[0011] Step S3: Start the drone, and the high-resolution camera is aimed at the feature identification area to capture images, accurately identify the feature identification on the cantilevered aerial platform, and transmit the captured images to the control system through the multi-sensor system. The control system analyzes the images and establishes a coordinate system to determine the initial coordinates and the initial state of the platform.

[0012] Step S4: The cantilevered aerial platform is raised to a set height until it reaches the design elevation and meets the installation requirements. During the raising process, the drone is raised synchronously and continuously takes images of the feature marking area. The control system analyzes the feature markings through real-time position information to monitor and calculate the horizontal and vertical displacement values ​​of the cantilevered aerial platform; and makes dynamic adjustments based on the calculated displacement.

[0013] Step S5: After the cantilevered aerial platform is raised to its position, the post-installed rods are installed to form a complete load-bearing system. The hydraulic synchronous lifting system is unloaded in stages according to sequence until the load of the cantilevered aerial platform is completely transferred to the steel column. The hydraulic synchronous lifting system is then dismantled to complete the lifting operation of the cantilevered aerial platform, and the drone is controlled to return.

[0014] In some embodiments, during a formal lift, the drone takes an image of the feature-marked area every 5 seconds and transmits it back to the control system via the multi-sensor system.

[0015] In some embodiments, both the drone and the control system include a GPS communication module, and the drone and the control system are wirelessly connected and transmit images through two GPS communication modules.

[0016] In some embodiments, the control system further includes a user terminal that can present the analyzed offset information to supervisors and technicians.

[0017] In some embodiments, step S1 includes the following operations:

[0018] An assembly frame is installed at the top of the basement; the assembly frame is welded together to form the cantilevered aerial platform, and auxiliary positioning feature marks are arranged at the corresponding measurement points on the cantilevered aerial platform;

[0019] The hydraulic synchronous lifting system is installed on the steel column;

[0020] A lower lifting point is set on the cantilevered aerial platform, an upper lifting point is set on the hydraulic synchronous lifting system, steel strands are installed between the upper and lower lifting points, and system debugging and fine-tuning of the lifting points are carried out.

[0021] In some embodiments, in step S4, when the offset value exceeds the upper limit, the lifting speed of the cantilevered aerial platform is reduced, and fine adjustments or jogging are made as necessary, so that each lifting point of the cantilevered aerial platform slowly and sequentially reaches the design elevation to meet the installation requirements.

[0022] In some embodiments, in step S2, after the cantilevered aerial platform is suspended, the lifting is paused, the height of each lower suspension point is measured, the elevation of each suspension point of the lifting unit is finely adjusted so that each lower suspension point is on the same horizontal line, and it is left to stand for 2 to 24 hours to check for any abnormalities in the hydraulic synchronous lifting system, and the height of each lower suspension point is measured again and compared with that when it is off the ground. After confirming that there are no abnormalities, the formal lifting begins.

[0023] In some embodiments, in step S4, a lifting verification is performed before the cantilevered aerial platform is lifted to a set lifting height;

[0024] The specific verification process is as follows:

[0025] After the hydraulic synchronous lifting system drives the cantilevered aerial platform to synchronously rise to the designed elevation in the height direction, the lifting is paused; the actual lifting height of each lifting point is measured and compared with the designed elevation, the data is recorded, the error percentage is obtained, and the lifting speed of each lifting point is fine-tuned;

[0026] The drone synchronously raises the design elevation in the vertical direction; it captures, transmits, and analyzes images of the feature-marked area to obtain the corresponding coordinate values, compares them with the platform's initial state, records them, and establishes a function of offset value and error percentage.

[0027] In some embodiments, during the process of the drone being lifted to a set height on the cantilevered aerial platform, it switches to a vertical lifting mode, in which the drone can only move in the vertical direction.

[0028] In some embodiments, the loading order in step S2 is: 30%, 50%, 65%, 75%, 85%, 95%, 100%.

[0029] The above-described technical solutions in the embodiments of the present invention have at least the following technical effects or advantages:

[0030] (1) By using the high-resolution camera and multi-sensor system carried by the UAV, the cantilevered aerial platform can be monitored in all directions in real time, reducing human error in the monitoring process, making the monitoring effect more accurate, and the horizontal and longitudinal displacement of the cantilevered aerial platform can be captured more reliably.

[0031] (2) The horizontal and longitudinal displacements of the cantilevered aerial platform are analyzed and calculated through the control system connected by radio. Based on the calculation results, the hydraulic synchronous lifting system is dynamically adjusted to realize real-time all-round monitoring of the synchronous lifting process of the cantilevered aerial platform, improve the safety and efficiency of lifting, and reduce the risks and losses in the lifting process.

[0032] (3) Through the user terminal, the analyzed deviation is presented to the supervisor and technical personnel, so that they can understand and control the lifting status of the cantilevered aerial platform in real time, and improve the visualization and controllability of the lifting process.

[0043] refer to Figure 1-3 The present invention provides a method for hydraulically lifting a cantilevered aerial platform with the assistance of a drone, comprising a steel column, a hydraulic synchronous lifting system, and a cantilevered aerial platform 1. The hydraulic synchronous lifting system can drive the cantilevered aerial platform 1 to move in the vertical direction, and the cantilevered aerial platform 1 is provided with a feature mark for auxiliary positioning.

[0044] It also includes a drone 2, which is equipped with a high-resolution camera and a multi-sensor system. The high-resolution camera and the multi-sensor system work together to achieve all-round real-time monitoring of the cantilevered aerial platform 1. The drone 2 is wirelessly connected to the control system. It can take pictures of the feature marking area through the high-resolution camera. The feature marking can assist in positioning and is transmitted back to the control system. The control system analyzes the image and establishes a coordinate system to determine the initial coordinates and the initial state of the platform. By analyzing and calculating the difference of the feature marking in the coordinate system in the images taken by the drone 2 at different positions, the monitoring of the lifting process of the cantilevered aerial platform 1 can be achieved.

[0045] The control system may include a server and a user terminal. The server may include a GPS communication module and an image analysis module. The server can wirelessly connect with the UAV 2 through the GPS communication module and receive images transmitted by the UAV 2. The image analysis module can analyze and process the transmitted images, calculate the offset, and send it to the user terminal.

[0046] The method for hydraulically lifting a cantilevered aerial platform assisted by a drone according to the present invention includes the following steps:

[0047] Step S1: Install the hydraulic synchronous lifting system, assemble the cantilevered aerial platform 1, and place auxiliary positioning feature marks at the corresponding measurement points on the cantilevered aerial platform 1.

[0048] The specific steps are as follows:

[0049] An assembly frame is set up at the top of the basement; a cantilevered aerial platform 1 is assembled and welded on the assembly frame, and auxiliary positioning feature marks such as QR codes and color marks are placed at the corresponding measurement points on the cantilevered aerial platform 1.

[0050] A hydraulic synchronous lifting system is installed on the steel column. The hydraulic synchronous lifting system may include a hydraulic pump, hydraulic cylinder, hydraulic oil tank, hydraulic valve, hydraulic pipeline, hydraulic sensor, etc. The hydraulic pump delivers hydraulic oil from the hydraulic oil tank to the hydraulic cylinder through the hydraulic pipeline. The hydraulic cylinder controls the flow and pressure of the hydraulic oil through the hydraulic valve, thereby controlling the extension and retraction of the hydraulic cylinder. The hydraulic sensor detects the position and pressure of the hydraulic cylinder in real time and transmits the signal to the control system.

[0051] A lower lifting point is set on the cantilevered aerial platform 1, and an upper lifting point is set on the hydraulic synchronous lifting system. Steel strands are installed between the upper and lower lifting points, and the system is debugged and the lifting points are finely adjusted to ensure that the cantilevered aerial platform 1 is connected to the hydraulic synchronous lifting system and remains horizontal.

[0052] Step S2: Trial lifting of the cantilevered aerial platform 1, loading in stages according to the design load sequence until the cantilevered aerial platform 1 is suspended in the air, checking the hydraulic synchronous lifting system again for any abnormalities, and comparing the measurement data with that at the time of lifting off the ground. After confirming that there are no abnormalities, prepare for the formal lifting.

[0053] The specific steps are as follows:

[0054] Start the hydraulic synchronous lifting system to slowly lift the cantilevered aerial platform 1, observe the movement of the cantilevered aerial platform 1, check the working status of the hydraulic synchronous lifting system, and record the height and pressure of each lifting point;

[0055] Load the load in stages according to the design load sequence, i.e., 30%, 50%, 65%, 75%, 85%, 95%, and 100%. After each loading, observe the changes in the cantilevered aerial platform 1, check the working status of the hydraulic synchronous lifting system, and record the height and pressure of each lifting point.

[0056] When the cantilevered aerial platform 1 reaches 100% of its design load, it will be suspended in mid-air, completely detached from the ground. At this point, lifting should be paused, the height of each lower lifting point should be measured, and the elevation of each lifting point of the lifting unit should be finely adjusted to ensure that each lower lifting point is on the same horizontal line. The platform should then be left to stand for 2 to 24 hours. The hydraulic synchronous lifting system should be checked again for any abnormalities, and the height of each lower lifting point should be measured again and compared with that at ground level. Once it is confirmed that there are no abnormalities, the formal lifting can begin.

[0057] Step S3: Start the drone 2, and use the high-resolution camera to capture images of the feature marking area to accurately identify the feature markings on the cantilevered aerial platform 1. Transmit the captured images to the control system through the multi-sensor system. The control system analyzes the images and establishes a coordinate system to determine the initial coordinates and the initial state of the platform.

[0058] The specific steps are as follows:

[0059] Launch drone 2, which is equipped with a high-resolution camera and a multi-sensor system. Drone 2 and the control system are wirelessly connected and transmit images through two GPS communication modules.

[0060] A high-resolution camera is aimed at the feature marking area to capture images. The feature marking area is the auxiliary positioning feature markings arranged on the cantilevered aerial platform 1, such as QR codes, color marks, etc. The high-resolution camera can clearly capture the shape, color, position and other information of the feature markings.

[0061] The multi-sensor system transmits captured images to the control system, which analyzes the images and establishes a coordinate system. The control system includes a user terminal, which can present the analyzed offset to the supervisor and technicians.

[0062] The control system uses image processing algorithms to accurately identify the feature markers in the image. Based on the shape, color, and position of the feature markers, it calculates the coordinates of the cantilevered aerial platform 1 in space, determines the initial coordinates and the initial state of the platform, i.e., the initial position of the cantilevered aerial platform 1.

[0063] Step S4: The cantilevered aerial platform 1 is raised to the set lifting height until it reaches the design elevation and meets the installation requirements. During the lifting process, the drone 2 is raised synchronously and continuously takes images of the feature marking area. The control system analyzes the feature markings through real-time position information and monitors and calculates the horizontal and longitudinal displacement values ​​of the cantilevered aerial platform 1. Dynamic adjustments are made based on the calculated displacement.

[0064] The specific steps are as follows:

[0065] Before the official upgrade, an upgrade verification process will be conducted. The specific verification process is as follows:

[0066] After the hydraulic synchronous lifting system drives the cantilevered aerial platform 1 to be raised synchronously to the design elevation in the height direction, the lifting is paused; the actual lifting height of each lifting point is measured and compared with the design elevation, the data is recorded, the error percentage is obtained, and the lifting speed of each lifting point is fine-tuned;

[0067] The UAV 2 synchronously raises the design elevation in the height direction; it takes pictures of the feature-marked areas, transmits and analyzes them to obtain the corresponding coordinate values, compares them with the initial state of the platform, records them, and establishes a function of offset value and error percentage.

[0068] During the actual lift, Drone 2 switches to vertical lift mode, in which it can only move vertically; thereby improving the accuracy of the images captured by Drone 2.

[0069] The hydraulic synchronous lifting system drives the cantilevered aerial platform 1 to lift synchronously in the vertical direction according to the set lifting speed and height until it is lifted to the design elevation to meet the installation requirements;

[0070] During the lifting process, UAV 2 lifts synchronously, taking pictures of the feature-marked area every 5 seconds and transmitting the images back to the control system through a multi-sensor system;

[0071] The control system analyzes feature identifiers based on real-time location information to monitor and calculate the offset values ​​of the horizontal and longitudinal displacements of the cantilevered aerial platform 1. The offset value is the difference between the actual coordinates and the design coordinates of the cantilevered aerial platform 1.

[0072] Dynamic adjustments are made based on the calculated offset, that is, the lifting speed and height of each lifting point of the hydraulic synchronous lifting system are finely adjusted according to the function of offset value and error percentage, so that each lifting point of the cantilevered aerial platform 1 slowly and sequentially reaches the design elevation to meet the installation requirements.

[0073] When the offset value exceeds the upper limit, reduce the lifting speed of the cantilevered aerial platform 1, and make fine adjustments or jogs if necessary to keep the horizontal and longitudinal displacement of the cantilevered aerial platform 1 within a reasonable range.

[0074] Step S5: After the cantilevered aerial platform 1 is lifted into position, the post-installed rods are installed to form a complete load-bearing system. The hydraulic synchronous lifting system is unloaded in stages according to sequence until the load of the cantilevered aerial platform 1 is completely transferred to the steel column. The hydraulic synchronous lifting system is then dismantled to complete the lifting operation of the cantilevered aerial platform 1, and the drone 2 is controlled to return.

[0075] refer to Figure 3 The sway range of the cantilevered aerial platform 1 during the lifting process is within ±300mm, and the safety distance should not be less than 200mm. If the above upper limit is exceeded, or if temporary fixation is required due to other special circumstances requiring work stoppage, a tie device 3 can be used. The tie device 3 may include four guide chains 3, one end of which is fixed to a corner of the cantilevered aerial platform 1, and the other end is fixed to a steel column for tie-up. The tie-up can be tensioned using a mechanical hoist to avoid excessive swaying of the cantilevered aerial platform 1.

[0076] The specific steps are as follows:

[0077] Once the cantilevered aerial platform 1 is raised to the designated position and reaches the design elevation, the lifting is stopped. The horizontal and longitudinal displacements of the cantilevered aerial platform 1 are checked to ensure they meet the design requirements. The height and pressure of each lifting point are recorded.

[0078] Install post-installed members, which are the connecting parts between the cantilevered aerial platform 1 and the steel column. They can be steel bars, steel pipes, steel cables, etc. The installation of post-installed members can be carried out by welding, bolts, clips, etc. The installation of post-installed members can be carried out during the lifting of the cantilevered aerial platform 1 or after the cantilevered aerial platform 1 has been lifted into place. The installation of post-installed members makes the cantilevered aerial platform 1 and the steel column form a complete force system to bear the self-weight and load of the cantilevered aerial platform 1.

[0079] The hydraulic synchronous lifting system unloads in stages in sequence: 95%, 85%, 75%, 55%, 35%, 20%, 10%, and 5%. After each unloading, the changes in the cantilevered aerial platform 1 are observed, the working status of the hydraulic synchronous lifting system is checked, and the height and pressure of each lifting point are recorded until the load of the cantilevered aerial platform 1 is completely transferred to the steel column, that is, the pressure of each lifting point of the hydraulic synchronous lifting system is zero.

[0080] The hydraulic synchronous lifting system was dismantled, including the hydraulic pump, hydraulic cylinder, hydraulic tank, hydraulic valve, hydraulic pipeline, hydraulic sensor and other components, as well as the steel strands, to complete the lifting operation of the cantilevered aerial platform 1.

[0081] The control drone 2 returns, and during the return process, the drone 2 takes a final picture of the cantilevered aerial platform 1 and transmits it back. The control system analyzes and saves the picture as the final record of the lifting operation of the cantilevered aerial platform 1.

[0082] In summary, this invention utilizes the high-resolution camera and multi-sensor system mounted on the UAV 2 to perform all-round real-time monitoring of the cantilevered aerial platform 1. By analyzing and processing the captured images through the control system, the horizontal and longitudinal displacements of the cantilevered aerial platform 1 can be precisely controlled and adjusted, thereby ensuring the safe and stable lifting of the cantilevered aerial platform 1.

[0083] This method utilizes the high-altitude flight capability and high-definition camera capability of UAV 2 to achieve all-round real-time monitoring of the cantilevered aerial platform 1, avoiding the inaccuracies and dangers of manual monitoring. UAV 2 connects to the control system via radio, transmitting the captured images to the control system for analysis and processing. The control system establishes a coordinate system based on the feature markers in the images, calculates the horizontal and longitudinal displacement offset values ​​of the cantilevered aerial platform 1, and dynamically adjusts the hydraulic synchronous lifting system according to the offset values, enabling the cantilevered aerial platform 1 to be lifted at the preset lifting height and speed while maintaining horizontal and vertical stability. The control system can also present the analyzed offset information to supervisors and technicians for timely detection and problem-solving. During the lifting process, UAV 2 can vertically ascend and descend or switch flight modes according to the actual situation to ensure the optimal viewing angle and distance to the cantilevered aerial platform 1. After being lifted into position, UAV 2 can return to the takeoff point or perform other tasks.

[0084] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
