Abstract
Description
Technical Field
[0001] This invention relates to the field of bridge construction technology, specifically to a system and method for monitoring and balancing the rotation of large-segment, wide-span rigid frame bridges. Background Technology
[0002] Bridge rotation construction refers to the technology of dynamically rotating the bridge body using external force-bearing axis equipment to achieve bridge positioning and closure. The biggest advantage of this technology is that it does not interfere with normal traffic operation, making it suitable for construction on urban main roads with high traffic density. When rotating a bridge, a ball joint device is generally used for rotation. Through the gradual installation and adjustment of various devices at the bottom, the stable rotation of the bridge is ensured. Under normal weather conditions, the external environment has little impact on it. However, in windy weather, the wind force directly acts on the rotating bridge body, and the force of the wind cannot be ignored, which may affect the bridge rotation action, thus limiting the bridge rotation construction. Therefore, in order to address the above problems, a monitoring and balancing system and method for the rotation of large-segment wide-span rigid frame bridges are proposed. Summary of the Invention
[0003] The purpose of this invention is to provide a system and method for monitoring and balancing the rotation of large-segment, wide-span rigid frame bridges, in order to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solution:
[0005] As an optional solution of the large-segment wide-span rigid frame bridge rotation monitoring and balancing system and method described in this invention, the large-segment wide-span rigid frame bridge rotation monitoring and balancing system and method includes a beam, bridge columns and a ball joint device.
[0006] The bottom of the beam is fixedly connected to a vertically installed bridge column, and the bottom of the bridge column is fixedly connected to a ball joint device, and a base is fixedly connected to the outside of the ball joint device.
[0007] Multiple sets of wind direction monitoring instruments are fixedly connected to the top of the beam.
[0008] Multiple sets of symmetrically arranged pressure detection modules are fixedly connected to both sides of the beam. A wind balance module is fixedly connected to the outside of the pressure detection module on one side, and the other end of the wind balance module is connected to an external air pump device.
[0009] An angle adjustment module is installed on one side of the beam, and guide frames are installed on both sides of the angle adjustment module. The outer side of the guide frames is fixedly connected to the beam.
[0010] The wind power balancing module includes a vent pipe, a fixing ring, and an air pipe. The outer side of each vent pipe is connected to an exhaust pipe, and the bottom of each vent pipe is connected to an air pipe. The other end of each air pipe is connected to an air pump device.
[0011] A fixing ring is rotatably connected to the outside of the vent pipe, and the outside of the fixing ring is fixedly connected to the pressure detection module. A solid tube is also fixedly connected to the top of the vent pipe, and a gear ring is fixedly connected to the outside of the solid tube. An angle adjustment module is engaged with the outside of the gear ring.
[0012] As an optional solution of the large-segment wide-span rigid frame bridge rotation monitoring and balancing system and method described in this invention, the pressure detection module includes an extrusion plate, a sliding column and a guide sleeve. A wind balancing module is installed on the outer side of the extrusion plate on one side. The outer side of the extrusion plate is fixedly connected to a uniformly distributed sliding column, and a pressure sensor is installed at the other end of the sliding column. The outer side of the pressure sensor is fixedly connected to the beam.
[0013] As an optional solution of the large-segment wide-span rigid frame bridge rotation monitoring and balancing system and method described in this invention, wherein: the outer side of each sliding column is slidably connected to a guide sleeve, and the other end of the guide sleeve is fixedly connected to a limit plate, and the outer side of the limit plate is fixedly connected to multiple connecting frames, and the other end of the connecting frame is fixedly connected to the beam.
[0014] Bridge rotation construction refers to the technique of dynamically rotating the bridge body using external load-bearing axis equipment to achieve bridge positioning and closure. The biggest advantage of this technology is that it does not obstruct normal traffic flow, making it suitable for construction on urban arterial roads with high traffic density. During bridge rotation, a ball joint device is generally used for rotation. Through the gradual installation and adjustment of various devices at the bottom, the stable rotation of the bridge is ensured. Under normal weather conditions, the external environment has minimal impact. However, in windy weather, the wind force directly acts on the rotating bridge body, and this force cannot be ignored, potentially affecting the bridge rotation and limiting the construction process. During use, symmetrically arranged pressure detection modules are installed on both sides of the beam. Once the wind blows and acts on the compression plate, the compression plate will slide. The column, with its sliding column pressing against the pressure sensor, measures the approximate compressive force of the wind. An external controller controls an air pump to quickly expel air through the wind balance module. The reaction force of this expelled air compresses the pressure plate on the leeward side, causing it to press against the sliding column pressure sensor. This applies similar forces to both sides of the beam, ensuring stable rotation and minimizing the impact of wind. As the beam rotates, the angle of the wind's action on the pressure plate gradually changes, altering the force detected by the pressure sensor. Activating the angle adjustment module then rotates the gear ring and solid tube, causing the exhaust pipe to rotate. This ensures the exhaust pipe always aligns with the wind direction, acting on the pressure plate to keep the pressure sensor readings on both sides within a suitable range, thus maintaining beam balance.
[0015] As an optional solution of the large-segment wide-span rigid frame bridge rotation monitoring and balancing system and method described in this invention, the angle adjustment module includes a mounting base and a hydraulic rod. The outer side of the mounting base is fixedly connected to the beam. The hydraulic rod is installed inside the mounting base. The free end of the hydraulic rod is fixedly connected to a mounting block. A motor is installed inside the mounting block. The end of the motor's main shaft is fixedly connected to a rotating shaft. A drive gear is fixedly connected to the outer side of the rotating shaft. A gear plate meshes with the outer side of the drive gear. One end face of the gear plate meshes with multiple sets of wind power balancing modules. A guide frame is also provided on the outer side of the gear plate, and the outer side of the guide frame is fixedly connected to the beam.
[0016] As an optional solution of the large-segment wide-span rigid frame bridge rotation monitoring and balancing system and method described in this invention, a protective plate is also installed on the outside of the mounting block, and the protective plate is located on the outside of the drive gear.
[0017] As an optional solution of the large-segment wide-span rigid frame bridge rotation monitoring and balancing system and method described in this invention, the gear plate has a groove on the side facing the beam, and each groove is equipped with a telescopic plate that can be extended and retracted, and the other end of the telescopic plate is fixedly connected to the beam.
[0018] As an optional solution to the large-segment wide-span rigid frame bridge rotation monitoring and balancing system and method described in this invention, wherein the interior of the mounting block is slidably connected to the gear plate.
[0019] When adjusting the angle of the wind balance module, the hydraulic rod is moved by starting the mounting base. At this time, the teeth on the outer side of the gear plate engage with the gear ring, and the docking is completed. The motor is started to drive the rotating shaft to rotate, which in turn drives the drive gear to rotate. The drive gear moves the gear plate, which can then drive the gear ring to rotate, thereby adjusting the angle of the exhaust pipe and facilitating the subsequent balancing of the forces on both sides of the beam.
[0020] As an optional solution to the large-segment, wide-span rigid frame bridge rotation monitoring and balancing system and method described in this invention, the usage steps are as follows:
[0021] Step 1: First, install the pressure detection modules on both sides of the beam that needs to be rotated, and arrange the pressure detection modules symmetrically.
[0022] Step 2: A wind balance module and an angle adjustment module are installed on the outside of the pressure detection module on the leeward side of the beam.
[0023] Step 3: When the ball joint device drives the bridge column to rotate, in the absence of wind or in a light breeze, it is not necessary to activate the pressure detection module, wind balance module, and angle adjustment module.
[0024] Step 4: When the wind volume is large, the pressure detection module is activated by the strong wind. At this time, the pressure detection module can roughly measure the force exerted by the wind on the beam. Then the wind balance module is activated to apply an appropriate force to the pressure detection module on the other side to ensure that the forces on both sides of the bridge column are balanced.
[0025] Step 5: As the bridge columns gradually rotate, the forces acting on the beam gradually change. At this point, the wind balance module is activated by starting the angle adjustment module to rotate, thereby balancing the wind forces on both sides of the beam and reducing the wind's impact on the beam's rotation.
[0026] Compared with the prior art, the beneficial effects of the present invention are:
[0027] In use, the present invention has symmetrically arranged pressure detection modules installed on both sides of the beam. Once the wind blows and acts on the compression plate, the compression plate squeezes the sliding column, and the sliding column squeezes the pressure sensor. At this time, the approximate squeezing force of the wind can be measured. The air pump equipment controlled by the external controller drives the air to be quickly discharged through the wind force balancing module. At this time, the reaction force of the air being discharged can squeeze the compression plate on the leeward side, and cause it to drive the sliding column to squeeze the pressure sensor, thereby applying similar forces to the beam on both sides. This is used to ensure the stable rotation of the beam and reduce the impact of the wind force.
[0028] As the beam rotates, the angle of the wind acting on the extrusion plate gradually changes, and the force detected by the pressure sensor changes. At this time, by activating the angle adjustment module, the gear ring and solid tube can be driven to rotate, thereby rotating the exhaust pipe. This ensures that the exhaust pipe is always aligned with the direction of the wind, which then acts on the extrusion plate, keeping the pressure sensor values on both sides within a suitable range, thus ensuring the balance of the beam.
[0029] When adjusting the angle of the wind balance module, the hydraulic rod is moved by starting the mounting base. At this time, the teeth on the outer side of the gear plate engage with the gear ring, and the docking is completed. The motor is started to drive the rotating shaft to rotate, which in turn drives the drive gear to rotate. The drive gear moves the gear plate, which can then drive the gear ring to rotate, thereby adjusting the angle of the exhaust pipe and facilitating the subsequent balancing of the forces on both sides of the beam.

[0037] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The present invention provides a technical solution:
[0038] A system and method for monitoring and balancing the rotation of a large-segment, wide-span rigid frame bridge, including the beam body 1, bridge column 2, and ball joint device 3;
[0039] The bottom of the aforementioned beam 1 is fixedly connected to a vertically arranged bridge column 2, and the bottom of the bridge column 2 is fixedly connected to a ball joint device 3, and the outer side of the aforementioned ball joint device 3 is fixedly connected to a base 4.
[0040] The top of the aforementioned beam 1 is fixedly connected to multiple sets of wind direction monitoring instruments 5;
[0041] Multiple sets of symmetrically arranged pressure detection modules 6 are fixedly connected to both sides of the aforementioned beam 1. A wind balance module 7 is fixedly connected to the outside of one side of the aforementioned pressure detection module 6, and the other end of the wind balance module 7 is connected to an external air pump device.
[0042] An angle adjustment module 8 is installed on one side of the beam 1, and guide frames 9 are installed on both sides of the angle adjustment module 8. The outer side of the guide frames 9 is fixedly connected to the beam 1.
[0043] The wind balance module 7 mentioned above includes a ventilation pipe 701, a fixing ring 702 and an air pipe 703. The outer side of the ventilation pipe 701 is connected to an exhaust pipe 704, and the bottom of the ventilation pipe 701 is connected to an air pipe 703. The other end of the air pipe 703 is connected to an air pump device.
[0044] A fixing ring 702 is rotatably connected to the outside of the aforementioned vent pipe 701, and the outside of the fixing ring 702 is fixedly connected to the pressure detection module 6. A solid tube 705 is also fixedly connected to the top of the aforementioned vent pipe 701, and a gear ring 706 is fixedly connected to the outside of the solid tube 705. An angle adjustment module 8 is engaged on the outside of the aforementioned gear ring 706.
[0045] The pressure detection module 6 includes an extrusion plate 601, a sliding column 602, and a guide sleeve 603. A wind balance module 7 is installed on the outer side of the extrusion plate 601 on one side. The outer side of the extrusion plate 601 is fixedly connected to the evenly distributed sliding column 602, and a pressure sensor 605 is installed at the other end of the sliding column 602. The outer side of the pressure sensor 605 is fixedly connected to the beam 1.
[0046] The outer side of each sliding column 602 is slidably connected to a guide sleeve 603, and the other end of the guide sleeve 603 is fixedly connected to a limiting plate 604. The outer side of the limiting plate 604 is fixedly connected to multiple connecting frames 606, and the other end of the connecting frame 606 is fixedly connected to the beam 1.
[0047] The usage steps are as follows:
[0048] Step 1: First, install the pressure detection module 6 on both sides of the beam 1 that needs to be rotated, and arrange the pressure detection modules 6 symmetrically.
[0049] Step 2: A wind balance module 7 and an angle adjustment module 8 are installed on the outside of the pressure detection module 6 on the leeward side of beam 1, respectively;
[0050] Step 3: When the ball joint device 3 drives the bridge column 2 to rotate, in the absence of wind or in a light breeze, it is not necessary to activate the pressure detection module 6, the wind balance module 7, and the angle adjustment module 8.
[0051] Step 4: When the wind volume is large, the pressure detection module 6 is activated by the strong wind. At this time, the pressure detection module 6 can roughly measure the force exerted by the wind on the beam 1. Then the wind balance module 7 is activated to apply an appropriate force to the pressure detection module 6 on the other side to ensure the force balance on both sides of the bridge column 2.
[0052] Step 5: As the bridge column 2 rotates, the force on the beam 1 gradually changes. At this time, the wind balance module 7 is rotated by activating the angle adjustment module 8 to balance the wind force on both sides of the beam 1 and reduce the wind's influence on the rotation of the beam 1.
[0053] Bridge rotation construction refers to the technology of dynamically rotating the bridge body using external force-bearing axis equipment to achieve bridge positioning and closure. The biggest advantage of this technology is that it does not obstruct normal traffic flow, making it suitable for construction on urban arterial roads with high traffic density. During bridge rotation, a ball joint device is generally used for rotation. Through the gradual installation and adjustment of various devices at the bottom, the stable rotation of the bridge is ensured. Under normal weather conditions, the external environment has little impact on it. However, in windy weather, the wind force directly acts on the rotating bridge body, and this force cannot be ignored, potentially affecting the bridge rotation and limiting the bridge rotation construction. During use, symmetrically arranged pressure detection modules 6 are installed on both sides of the beam 1. Once the wind blows and acts on the compression plate 601, the compression plate 601 compresses the sliding column 602, which in turn compresses the pressure sensor 6. At 05, the approximate compressive force of the wind can be measured. The air pump, controlled by an external controller, drives the air to be quickly discharged through the wind balance module 7. The reaction force of the discharged air can compress the compression plate 601 on the leeward side, causing it to drive the sliding column 602 to compress the pressure sensor 605. This applies a similar force to both sides of the beam 1, ensuring the stable rotation of the beam 1 and reducing the influence of the wind. As the beam 1 rotates, the angle of the wind on the compression plate 601 gradually changes, and the force detected by the pressure sensor 605 changes. At this point, by activating the angle adjustment module 8, the gear ring 706 and the solid tube 705 can be rotated, thereby causing the exhaust pipe 704 to rotate. The exhaust pipe 704 is always aligned with the direction of the wind, and then acts on the compression plate 601, keeping the values of the pressure sensors 605 on both sides within a suitable range, thus ensuring the balance of the beam 1.
[0054] In this embodiment, the input end of the air pipe 703 is connected to a separate air pump device, which is set on the ground to avoid the vibration of the air pump device affecting the rotation. A fixing ring 702 is installed on the outside of the air pipe 701 to ensure normal rotation under the drive of the solid pipe 705. The gear ring 706 cooperates with the angle adjustment module 8 to ensure that the angle can rotate normally. When not in use, the gear ring 706 is separated from the angle adjustment module 8.
[0055] The guide sleeve 603 ensures the stable movement of the sliding column 602 and serves as a guide. The limiting plate 604 and the connecting frame 606 support the guide sleeve 603. The extrusion plate 601 has a different shape and its shape can be designed according to the specific situation of the beam 1.
[0056] Example 2: This example is an improvement upon Example 1. Please refer to [link / reference]. Figure 5 and Figure 6Specifically, the aforementioned angle adjustment module 8 includes a mounting base 808 and a hydraulic rod 809. The outer side of the mounting base 808 is fixedly connected to the beam 1. The hydraulic rod 809 is installed inside the mounting base 808. The free end of the hydraulic rod 809 is fixedly connected to a mounting block 801. The mounting block 801 is installed inside a motor 802. The end of the main shaft of the motor 802 is fixedly connected to a rotating shaft 803. The outer side of the rotating shaft 803 is fixedly connected to a drive gear 804. The outer side of the drive gear 804 meshes with a gear plate 805. One end face of the outer side of the gear plate 805 meshes with multiple sets of wind power balancing modules 7. A guide frame 9 is also provided on the outer side of the gear plate 805, and the outer side of the guide frame 9 is fixedly connected to the beam 1.
[0057] A protective plate 807 is also installed on the outside of the aforementioned mounting block 801, and the protective plate 807 is located on the outside of the drive gear 804.
[0058] The gear plate 805 has a groove on the side facing the beam 1, and each groove is equipped with a telescopic plate 806 that can be extended and retracted. The other end of the telescopic plate 806 is fixedly connected to the beam 1.
[0059] The interior of the mounting block 801 is slidably connected to the gear plate 805.
[0060] When adjusting the angle of the wind balance module 7, the hydraulic rod 809 is moved by starting the mounting base 808. At this time, the teeth on the outer side of the gear plate 805 engage with the gear ring 706, and the docking is completed. The rotating shaft 803 is rotated by starting the motor 802, and the rotating shaft 803 drives the drive gear 804 to rotate. The drive gear 804 drives the gear plate 805 to move, which can be used to drive the gear ring 706 to rotate, thereby adjusting the angle of the exhaust pipe 704, which facilitates the subsequent balancing of the forces on both sides of the beam 1.
[0061] In this embodiment, the protective plate 807 is provided to protect the drive gear 804, and a groove is provided on one side of the gear plate 805 to ensure that the gear plate 805 slides stably under the guidance of the telescopic plate 806. The telescopic plate 806 can extend and retract to ensure that the gear plate 805 can move back and forth. The mounting block 801 is slidably connected to the gear plate 805, which serves as a guide to ensure that the gear plate 805 slides stably.
