Description

Technical Field

[0001] This utility model relates to the field of bridge rotation construction technology, specifically to a multi-point support rotation device based on intelligent dynamic control. Background Technology

[0002] The increasing maturity of bridge rotation technology has led to its wider application in the field, with rotating weights reaching new highs. However, when encountering irregular bridge shapes or large-eccentricity, high-tonnage rotating structures due to limitations in existing building space, the drawbacks of traditional rotating structures—such as high weight requirements, limited eccentricity handling, and limited adaptability—become apparent. In recent years, the bridge rotation technology field has been searching for a support structure with a high safety factor and economic feasibility to replace traditional ball joints in complex environments such as those with limited existing building space.

[0003] With the popularization of AI-powered intelligent building structures, the field of bridge rotation urgently needs structural innovation to adapt to new structural requirements. The support foot mentioned in this utility model is a multi-point support device that integrates real-time monitoring and dynamic balance control. The support foot cylinder is equipped with a hydraulic jacking device and various sensor devices, which can monitor the load borne by the support point in real time and control the jacking according to the load borne, so as to keep the rotation mechanism in balance during the rotation process.

[0004] Based on this, a multi-point support rotation device based on intelligent dynamic control is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0005] To address the aforementioned problems, a multi-point support rotation device based on intelligent dynamic control is provided, which solves the problems mentioned above.

[0006] To address the problems of existing technologies, this utility model provides a multi-point support rotation device based on intelligent dynamic control, including a ball joint, a support leg system, and an intelligent control system. The support leg system includes a layered outer cylinder structure and a dynamic lifting unit. The layered outer cylinder structure includes an upper outer cylinder, a waist plate, a lower outer cylinder, and a base plate. The upper and lower outer cylinders are welded together by the waist plate, and a sensor wiring groove is provided between the waist plates. A stiffening plate is arranged inside the upper outer cylinder and is cast and solidified with the upper turntable. Several surrounding cylinders and jacks are arranged inside the lower outer cylinder. The outside of the surrounding cylinders is filled with concrete. A polytetrafluoroethylene (PTFE) sliding plate is provided at the bottom of the base plate. The bottom of the jacks is installed on the PTFE sliding plate and contacts the slide rail through holes therein. The dynamic lifting unit includes an adapter jack and a sensor integration device.

[0007] Preferably, the sensor integration device includes a pressure ring, a pressure sensor, an tilt sensor, and a displacement sensor. The pressure ring is snapped onto the top of the jack, and the pressure ring has a terminal line groove inside, which is connected to the terminal line through a waist plate line hole.

[0008] Preferably, the intelligent control system includes a multi-source sensing layer, a dynamic response layer, and a closed-loop control layer; The multi-source sensing layer consists of pressure sensors, tilt sensors, and displacement sensors independently deployed on each support leg; The dynamic response layer generates jack lifting commands based on real-time load / displacement data using a PID algorithm; The closed-loop control layer is used to achieve pre-leveling before rotation, dynamic balancing during rotation, and automatic locking after rotation.

[0009] Preferably, the multi-source sensing layer acquires real-time load, displacement, and tilt data at a frequency of 10Hz.

[0010] Preferably, the dynamic response layer analyzes the sensor data through an edge computing terminal to calculate the lifting compensation amount of each support leg.

[0011] Preferably, the closed-loop control layer drives the jack to perform millimeter-level dynamic adjustments and feeds back the execution effect to the multi-source sensing layer to form a closed-loop control.

[0012] The advantages of this utility model compared to the prior art are: 1. This utility model uses pressure sensors, tilt sensors, and displacement sensors inside the intelligent support legs to monitor the displacement and load of each support point in real time. The system analyzes the displacement and load data and converts it into commands to control the jacks in each support leg to lift the structure, keeping the rotating mechanism in a balanced state throughout the entire rotation until it rotates to the designated position at the designed elevation. This eliminates the need for posture adjustment after rotation, which is required in traditional rotating structures, thus saving rotation window time.

[0013] 2. This utility model can directly convert data into rotation parameters by recording the power output of the jack through the sensors inside the support leg, eliminating the need for trial rotation. This utility model's rotation support leg has the advantages of strong innovation, strong adaptability, and good economy.

[0014] 3. This utility model uses a multi-point support structure, and each intelligent support leg can maintain structural balance through different lifting loads. Within the power range of the lifting jack, the amount of concrete counterweight blocks required can be reduced, and the overall price of the rotating ball joint is low.

[0015] 4. This utility model increases the surrounding support points of the structure to be rotated by installing jacks inside the support legs. All support legs are in contact with the slide during rotation, directly bearing the rotation weight of the upper structure and distributing the pressure of the ball joint. This can reduce the size and model of the ball joint, and has a certain degree of economy. Attached Figure Description

[0022] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0023] Reference Figures 1-5 A multi-point support rotating device based on intelligent dynamic control includes a ball joint 3, a support foot system, and an intelligent control system. The support foot system includes a layered outer cylinder structure and a dynamic lifting unit. The layered outer cylinder structure includes an upper outer cylinder 11, a waist plate 13, a lower outer cylinder 14, and a bottom plate 15. The upper outer cylinder 11 and the lower outer cylinder 14 are welded together by the waist plate 13. A sensor circuit groove 131 is provided between the waist plates 13. A stiffening plate 12 is arranged inside the upper outer cylinder 11 and is cast and solidified with the upper turntable. Several surrounding cylinders 17 and jacks 16 are arranged inside the lower outer cylinder 14. The surrounding cylinders 17 are filled with concrete. A polytetrafluoroethylene sliding plate 18 is provided at the bottom of the bottom plate 15. The bottom of the jacks 16 is installed on the polytetrafluoroethylene sliding plate 18 and contacts the slide rail 2 through the holes thereon. The PTFE sliding plate 18 has an extremely low coefficient of friction, which effectively reduces the friction between the bottom of the jack 16 and the slide rail 2, making the jack 16 operate more smoothly during lifting. The bottom of the jack 16 is mounted on the PTFE sliding plate 18 and contacts the slide rail 2 through holes therein. This design allows the jack 16 to stably apply lifting force to the rotating structure. The dynamic lifting unit includes an adapter jack 16 and a sensor integration device 19.

[0024] The dynamic lifting unit includes an adapter jack 16 and a sensor integration device 19. The sensor integration device 19 is a key component for achieving intelligent dynamic control; it includes a pressure ring 191, a pressure sensor 193, a tilt sensor 192, and a displacement sensor 194. The pressure ring 191 is fitted onto the top of the jack 16, accurately transmitting the pressure applied by the jack 16 to the pressure sensor 193, thereby monitoring the lifting pressure of the jack 16 in real time. The pressure ring 191 has a terminal wiring groove 195 inside, which connects to the terminal wiring 196 through wiring holes in the waist plate 13. This wiring connection method ensures that sensor data can be stably transmitted to the terminal of the intelligent control system for analysis and processing.

[0025] The sensor integration device 19 includes a pressure ring 191, a pressure sensor 193, an tilt sensor 192, and a displacement sensor 194. The pressure ring 191 is clamped onto the top of the jack 16. The pressure ring 191 has a terminal line groove 195 inside, and it is connected to the terminal line 196 through the line hole of the waist plate 13.

[0026] The intelligent control system includes a multi-source sensing layer, a dynamic response layer, and a closed-loop control layer. The multi-source sensing layer consists of a pressure sensor 193, an tilt sensor 192, and a displacement sensor 194 independently deployed on each support leg 1; The dynamic response layer generates jack 16 lifting commands based on real-time load / displacement data and through a PID algorithm. The closed-loop control layer is used to achieve pre-leveling before rotation, dynamic balancing during rotation, and automatic locking after rotation.

[0027] The multi-source sensing layer collects real-time load, displacement, and tilt data at a frequency of 10Hz.

[0028] The dynamic response layer analyzes sensor data through an edge computing terminal to calculate the lifting compensation amount of each support leg 1.

[0029] The closed-loop control layer drives the jack 16 to perform millimeter-level dynamic adjustments and feeds back the execution effect to the multi-source sensing layer, forming a closed-loop control.

[0030] The multi-source sensing layer consists of independently deployed pressure sensors 193, tilt sensors 192, and displacement sensors 194 on each support leg 1. These sensors can collect real-time load, displacement, and tilt data of the rotating structure at different locations, providing comprehensive and accurate information for the intelligent control system. The multi-source sensing layer collects real-time load, displacement, and tilt data at a frequency of 10Hz. This high-frequency acquisition can promptly capture minute changes in the structural state during the rotation process, providing timely and accurate data support for subsequent dynamic response and closed-loop control. The dynamic response layer generates lifting commands for jack 16 based on real-time load / displacement data using a PID algorithm. The PID algorithm is a classic control algorithm that can quickly and accurately calculate the required lifting adjustment for jack 16 based on the current error and its trend, thereby achieving precise control of the rotating structure's attitude. The dynamic response layer analyzes sensor data through an edge computing terminal to calculate the lifting compensation for each support leg 1. The use of the edge computing terminal enables rapid local processing of sensor data, reducing data transmission latency and improving the system's response speed and control accuracy. The closed-loop control layer is used to achieve pre-leveling before rotation, dynamic balancing during rotation, and automatic locking after rotation. Before rotation, the closed-loop control layer uses data collected by the multi-source sensor layer to drive jack 16 to pre-level the rotating structure, ensuring that the structure is in a balanced state in the initial stage, laying a good foundation for the subsequent rotation process. During rotation, the closed-loop control layer drives jack 16 to perform millimeter-level dynamic adjustments based on the lifting commands generated by the dynamic response layer, adjusting the posture of the rotating structure in real time to maintain dynamic balance. Simultaneously, the closed-loop control layer feeds back the execution results to the multi-source sensor layer, forming a closed-loop control system. This closed-loop control method can continuously adjust and optimize the control commands based on the actual execution results, ensuring the accuracy and stability of the rotation process. After rotation, the closed-loop control layer can control jack 16 to hold the structure in place, ensuring the rotating structure is stable and reliable in the new position, awaiting subsequent consolidation work.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
