Description

Technical Field

[0001] The utility model relates to the technical field of pile-driving ship construction monitoring, and more specifically, to an integrated system of oil cylinder digital twin platforms. Background Art

[0002] Pile-driving vessels are special vessels used for pile foundation construction. They usually use extra-large and extra-long hydraulic cylinders to provide force and control to ensure construction quality and safety. However, with the widespread application of hydraulic cylinders in pile-driving vessels and other fields, their working conditions and performance requirements have become complex and challenging. Traditional construction processes and equipment control can no longer meet the requirements for high-precision, high-reliability intelligent equipment construction and maintenance under the new situation.

[0003] The working characteristics of pile-driving vessels include offshore operations, hull stability, large hydraulic systems, precise positioning, adaptability to various working conditions, and construction monitoring and recording. The performance and stability of hydraulic cylinders are crucial to ensuring construction quality and safety. At present, the performance monitoring of hydraulic cylinders mostly stays on oil pressure, operating speed, and the process of controlling the operation of hydraulic cylinders. There is little monitoring and analysis of the working parameters of hydraulic cylinders, optimization of hydraulic systems, load conditions, and environmental conditions. There is an urgent need for a monitoring system that can truly reflect the operating status of the cylinders and the performance status of key components to improve the construction efficiency of pile-driving vessels, reduce energy consumption and loss, and improve construction safety.

[0004] Digital twin technology has been introduced as a way to address these challenges. The digital twin platform converts the physical characteristics and performance of the actual hydraulic cylinder into a digital model, and uses computer simulation technology to represent the geometric characteristics, performance, status and function of the hydraulic cylinder. This technology can not only be used to simulate the working parameters of the hydraulic cylinder, but also to optimize the hydraulic system, analyze the load conditions and monitor the working environment status.

[0005] Digital twin technology can help develop maintenance plans, conduct online performance evaluations, predict component life, and optimize the design and operation of the entire piling system. Due to the complex working environment of hydraulic cylinders, digital twin systems are required to implement online performance evaluation functions and reflect the working performance of key components in real time to avoid greater losses. The life prediction of key components is also of great significance for long-term construction operations.

[0006] The operation of extra-large and extra-long hydraulic cylinders on piling vessels is a critical engineering activity, and its performance and reliability have a significant impact on construction quality and safety. The introduction of digital twin technology provides an advanced method for optimizing the construction process and improving equipment performance, providing strong support for the development of technology in this field to meet the needs of extra-large and extra-long hydraulic cylinders on piling vessels.

[0015] Other advantages, objectives and features of the present invention will be embodied in part through the following description, and in part will be understood by those skilled in the art through research and practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 This is a framework diagram of the utility model. DETAILED DESCRIPTION

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0018] In the description of the present invention, terms such as "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0019] like Figure 1As shown, the digital twin platform integrated system of the oil cylinder of the utility model includes a sensor component and a host computer based on a digital twin simulation model. The sensor component includes a sealing performance monitoring sensor. The sealing performance monitoring sensor includes a pressure sensor, a speed sensor and a high-definition camera respectively connected to the host computer. The pressure sensor is installed at the oil inlet and oil outlet of the oil cylinder to monitor the oil pressure changes at the corresponding positions. The speed sensor is installed on the piston rod to collect the axial velocity and acceleration of the piston rod. The high-definition camera is installed at the end cover of the oil cylinder and the sealing connection between the piston rod and the cylinder cover to determine whether there is external leakage in the hydraulic cylinder. The collected data is obtained through the host computer and displayed in real time.

[0020] The sensor assembly is equivalent to the data acquisition subsystem. Each sensor is set according to the corresponding acquisition and installation requirements. The sensor assembly is set to set corresponding sensors at key positions during the operation of the pile driver cylinder for data monitoring. Since the internal leakage of the hydraulic cylinder is proportional to the inlet and outlet pressure difference of the hydraulic cylinder and inversely proportional to the viscosity of the oil, a pressure sensor is set accordingly. By measuring the inlet and outlet oil pressures, the pressure difference can be obtained, which can effectively reflect the internal leakage of the hydraulic cylinder. If a step signal appears in the axial speed and acceleration of the piston rod, it can also indirectly reflect that there may be problems with the sealing performance of the cylinder. The high-definition camera is set to take images of the end cover and the seal to observe and identify the external leakage of the oil. The host computer of the prior art has the ability to realize logical control based on the digital twin simulation model, and it is common to perform data comparison and model prediction functions. A simulation model based on the digital twin of the hydraulic system of the pile driver is established in the host computer, and the sensor component is used as the signal input source. The digital twin simulation model of the host computer is used to simulate and predict the life. The cylinder digital twin platform integrated system of the utility model is provided with a sensor component and a host computer based on the digital twin simulation model. The host computer is connected to the sensor component, and the collected data is integrated and displayed on the host computer to construct a cylinder digital twin platform, so as to realize visual real-time monitoring of the motion state of the super-large and super-long cylinder, and can obtain the specific collection data or images of the pressure sensor, speed sensor and high-definition camera, and through the introduction of image acquisition and presentation recognition, it can realize the comprehensive monitoring and evaluation of the sealing performance of the cylinder, improve the authenticity and accuracy of the working state and performance judgment of the cylinder, and can predict the life of the key components related to the cylinder through the real-time acquisition data of the sensor component.

[0021] In another technical solution, Figure 1As shown, the sensor assembly also includes a joint bearing monitoring sensor, which includes a noise sensor, a vibration sensor, a thermal imager, a high-definition camera, a pin sensor and an angle encoder respectively connected to the host computer. The noise sensor is installed at the friction pair of the joint bearing to collect noise data at the friction pair, the vibration sensor is installed on the joint bearing base to collect vibration data of the joint bearing, the thermal imager is installed at the base of the joint bearing to collect the maximum temperature data of the outer surface of the joint bearing, the high-definition camera is installed on the joint bearing base to collect images of debris and wear generated by the joint bearing clearance, the pin sensor is installed on the joint bearing to collect the load borne by the joint bearing, and the angle encoder is installed at the rotation pair of the joint bearing to collect the rotation angle data of the joint bearing.

[0022] For the performance monitoring and evaluation of spherical bearings, corresponding monitoring data are obtained by setting up noise sensors, vibration sensors, thermal imagers, high-definition cameras, pin sensors and angle encoders. The temperature measured by the thermal imager, the image of wear objects taken by the high-definition camera and the noise data measured by the noise sensor can all be used as the basis for judging the performance of spherical bearings.

[0023] In another technical solution, Figure 1 As shown, the sensor assembly also includes a piston rod monitoring sensor, which includes a displacement sensor and a high-resolution camera respectively connected to the host computer. The displacement sensor is installed at the piston rod head to monitor the tiny displacement at the piston rod head, and the high-resolution camera is used to scan the surface of the piston rod to form a surface image of the piston rod.

[0024] When the piston rod surface is severely worn, it will cause radial runout of the piston rod. Therefore, the wear condition of the piston rod surface can be judged by detecting the slight displacement at the piston rod head as the radial runout of the piston rod. In addition, the wear condition of the piston rod surface can be judged by scanning the piston rod surface with a high-resolution camera through visual processing and comparative analysis.

[0025] In another technical solution, Figure 1 As shown, a data evaluation module is also provided on the host computer, and the data evaluation module is used to set a data evaluation threshold, obtain the collected data of the pressure sensor, the speed sensor, the high-definition camera, the noise sensor, the vibration sensor, the thermal imager, the high-definition camera, the pin sensor, the angle encoder, the displacement sensor, and the high-resolution camera, and compare the data with the corresponding data evaluation threshold to determine whether there is a problem with the equipment performance.

[0026] Using the digital twin simulation model of the host computer, the data evaluation threshold is set in the data evaluation module. During the operation of the hydraulic system, pressure sensors, speed sensors, high-definition cameras, noise sensors, vibration sensors, thermal imagers, high-definition cameras, pin sensors, angle encoders, displacement sensors, and high-resolution cameras detect real-time data and transmit the data to the host computer. The host computer simulates in the digital twin model based on the transmitted real-time data, predicts the performance data of each parameter after a period of time, and compares it with the data evaluation threshold. If the data evaluation threshold is exceeded, it means that the life of the structural components cannot guarantee normal operation and needs to be inspected and repaired in advance. High-definition cameras, high-definition cameras, and high-resolution cameras are very common in this technical field, with various varieties and complete functions. You only need to purchase products with corresponding resolution and functional requirements according to your needs, and perform shooting, image data transmission, and image recognition.

[0027] In another technical solution, Figure 1 As shown, the host computer includes a display and a keyboard connected in communication, a human-computer interaction interface is set on the display, the data evaluation threshold is set through the human-computer interaction interface, and all collected data are displayed on the touch screen. The display is set with a human-computer interaction interface, which can display and monitor the oil cylinder data collected by the sensor component in real time, so as to facilitate the judgment of the working status and performance of the oil cylinder.

[0028] In another technical solution, Figure 1 As shown, it also includes an alarm module connected to the host computer, which is used to issue an alarm after receiving an alarm signal sent by the host computer, prompting the staff to check and repair the corresponding structural components with abnormal data that exceed the set range threshold.

[0029] To summarize, the patented cylinder digital twin platform integrated system obtains the data of the key components of the cylinder collected by the sensor components through the host computer, displays it on the human-computer interaction interface, and monitors the status of the pile-driving ship, hydraulic cylinder, and working environment during the construction process in real time. When the data is abnormal, a warning is issued through the alarm module to prompt the staff to conduct inspections and repairs. In addition, the host computer can be used to perform visual analysis of the key components of the cylinder to help predict the operating life and realize the integration of various functional requirements of the cylinder digital twin.

It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the drawings shown and described herein.
