For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] For the purpose of simplicity and illustration, the principles of the embodiments are mainly described by reference to examples. In the following description, many specific details are proposed to provide a thorough understanding of the embodiments. However, it is obvious that for those of ordinary skill in the art, these embodiments may not be limited to these specific details in practice. In some instances, known methods and structures are not described in detail to avoid making these embodiments unnecessarily difficult to understand. In addition, all embodiments can be used in combination with each other.

[0040] See also Figures 1 to 6 , the present invention provides a technical solution:

[0041] Embodiment 1 is a steel box girder pre-camber intelligent adjustment mechanism, the steel box girder comprises a plurality of box girder individual units 1 arranged side by side, the plurality of box girder individual units 1 are arranged side by side and welded and fixed in sequence to form a complete steel box girder.

[0042] Specifically, flanges 2 are provided on both sides of the steel box girder to increase the overall width of the steel box girder, and an actuator 3 is provided below the steel box girder to support the steel box girder;

[0043] Among them, the actuator 3 includes two lower chords 31 and an upper chord 311, and the three are distributed in a triangular shape below the steel box girder. The two lower chords 31 are symmetrically distributed on both sides below the upper chord 311. A plurality of support members 32 distributed at equal intervals are arranged between the two lower chords 31. A pressure sensor 34 is installed on the top of the support member 32, and the pressure sensor 34 is against the lower surface of the box girder individual unit 1. The support member 32 is used to support the box girder individual unit 1 directly above it. According to the target pre-arch of the steel box girder, the upper end surface height of each support member 32 is different. After the box girder individual unit 1 is supported by the upper end of the support member 32, a plurality of box girder individual units 1 can form a steel box girder with a certain arch structure. An adjusting block 322 is installed inside the support member 32. Linkage rods 33 are rotatably installed on both sides of the adjusting block 322 through hinge supports 323. One end of the two linkage rods 33 is movably sleeved on the outer sides of the two lower chords 31, such as Figure 3As shown, when the two lower chords 31 approach or move away from each other, the linkage rod 33 can rotate accordingly and drive the support member 32 to move up and down in the vertical direction. According to the different height positions of the adjustment block 322 inside the support member 32, the multiple support members 32 can be located at different height positions, thereby realizing the control of the pre-camber of the steel box girder. When the pressure sensor 34 supports the individual unit 1 of the box girder, it can monitor the downward pressure generated by the individual unit 1 of the box girder in real time. According to the pressure data monitored by the pressure sensor 34 at each position, the stress distribution of the steel box girder can be determined;

[0044] Secondly, a driving member 35 is arranged between the two lower chords 31, and the driving member 35 drives the lower chord 31 to move. The driving member 35 and the pressure sensor 34 are both electrically connected to the external control system. The pressure sensor 34 monitors the pressure exerted on it by the individual unit 1 of the box beam, and is analyzed and processed by the external intelligent control system. Then, the driving member 35 is extended and retracted to control the movement of the lower chord 31, and then the supporting member 32 is driven to rise and fall through the linkage rod 33.

[0045] In order to drive the lower chord rod 31 to move, the present application also has sleeves 351 fixedly installed at both ends of the driving member 35, and the sleeves 351 are movably sleeved on the outer side of the lower chord rod 31. The driving member 35 is provided with multiple and spaced apart distributions with multiple support members 32, such as Figure 3 As shown, when the driving member 35 is extended or retracted, the connection between the sleeve 351 and the lower chord rod 31 can drive the two lower chord rods 31 to move closer to or farther from each other.

[0046] In order to control the height position of a single support member 32, the present application also has an adjustment slot 321 running through the lower half of the support member 32, an adjustment block 322 is slidably installed in the inner cavity of the adjustment slot 321 and adapted thereto, an adjustment screw 325 is rotatably installed in the inner cavity of the adjustment slot 321, a threaded hole 324 is vertically running through the middle of the adjustment block 322, the adjustment screw 325 passes through the threaded hole 324 and is threadedly connected thereto, a motor 326 for driving the adjustment screw 325 to rotate is installed at the lower end of the support member 32, and the motor 326 is electrically connected to the external control system, combined with Figure 3 , Figure 4 and Figure 5As shown, the motor 326 is started and stopped by an external intelligent control system. When the motor 326 is working, it can drive the adjusting screw 325 to rotate and drive the adjusting block 322 and the support member 32 to move relative to each other in the vertical direction. Due to the existence of the linkage rod 33, the relative position between the adjusting block 322 and the lower chord rod 31 is fixed at this time. Therefore, when the adjusting screw 325 rotates, it will drive the support member 32 to move up and down in the vertical direction, thereby changing the height position of the support member 32. When the support member 32 rises, the support member 32 can push the box beam individual unit 1 at the corresponding position to move upward. Since the box beam individual unit 1 and the box beam individual unit 1 next to it need to be welded, the box beam individual unit 1 will be slightly tilted. Multiple box beam individual units 1 are tilted in sequence, so that the steel box beam as a whole forms a bow-shaped structure with an upward arch in the middle, thereby realizing the adjustment of the pre-arch of the steel box beam.

[0047] In order to prevent the support member 32 from tilting, the present application also has a waist hole 327 penetrating through the upper half of the support member 32, and the upper chord rod 311 sequentially moves through the waist holes 327 on multiple support members 32, and the outer sides of the two ends of the waist hole 327 are sleeved with anti-slip nuts 313, such as Figure 3 and Figure 1 As shown, the upper chord 311 is used to limit the upper half position of multiple support members 32 to prevent a single support member 32 from tilting and failing to provide stable support for the individual box girder units 1. The waist hole 327 is configured to allow the upper chord 311 and the support members 32 to slide relative to each other over a certain distance in the vertical direction, thereby accommodating support members 32 at different heights.

[0048] In order to place the lower chord 31, the present application also has support beams 4 provided below both ends of the lower chord 31 to support it. The support beams 4 are installed on the ground through a stand. The two lower chords 31 are placed horizontally. Limit blocks 312 are fixedly provided at both ends of the lower chord 31, and the sides of the limit blocks 312 are in contact with the sides of the support beams 4. The setting of the limit blocks 312 can prevent the lower chord 31 from sliding along its own length direction and causing it to separate from the support beams 4.

[0049] In order to install the pressure sensor 34, the present application also has a mounting seat 328 fixedly installed on the top of the support member 32. The mounting seat 328 and the support member 32 form a "T" shape as a whole. The upper surface of the mounting seat 328 is an upward convex arc shape, which can adapt to the inclined box beam individual unit 1. When the box beam individual unit 1 has a certain inclination, the box beam individual unit 1 can still be stably pressed on the upper end of the support member 32. The pressure sensor 34 is installed in the middle of the mounting seat 328 and the upper surface of the pressure sensor 34 is located above the mounting seat 328.

[0050] An adjustment method according to the above-mentioned steel box girder pre-camber intelligent adjustment mechanism specifically comprises the following steps:

[0051] Step 1: Initialization settings: set the initial pre-camber value and the target pre-camber value. Set the initial pre-camber value, which is usually determined based on the bridge design requirements and actual working conditions. Set the target pre-camber value, which is the pre-camber state that the bridge is expected to achieve during operation.

[0052] Step 2: Real-time data monitoring: using the pressure sensor 34 to monitor the pre-camber change and stress distribution of the steel box girder in real time. The pressure sensor 34 transmits the collected data to the intelligent control system to ensure the real-time and accuracy of the data;

[0053] Step 3: Data reception and verification: the external intelligent control system receives the monitoring data of the pressure sensor 34 and verifies the integrity and accuracy of the data;

[0054] Step 4: Data analysis and processing. After receiving the sensor data, the intelligent control system uses the built-in control algorithm and data processing technology to process and analyze the data, analyze the difference between the current pre-camber value and the target pre-camber value, and the change trend of the stress distribution, and predict the future deformation and stress of the steel box girder based on the analysis results;

[0055] Step 5: Calculate the adjustment plan. Based on the prediction results and bridge design requirements, the intelligent control system calculates the best pre-camber adjustment plan. The adjustment plan usually includes parameters such as the position of the support point to be adjusted, the adjustment height, and the adjustment speed.

[0056] Step 6: Execute structural control. The intelligent control system converts the adjustment plan into a control signal and sends it to the actuator 3. The actuator 3 adjusts the height and position of the support point according to the control signal to adjust the pre-camber of the steel box girder. During the adjustment process, the actuator 3 feeds back the adjustment status to the intelligent control system in real time to ensure the accuracy and stability of the adjustment.

[0057] Step 7: Evaluation of adjustment effect: after the adjustment is completed, the intelligent control system receives the data from the pressure sensor 34 again and evaluates the adjustment effect. If the adjustment effect meets the requirements, the adjustment process is terminated; if the adjustment effect is not satisfactory, the adjustment plan is recalculated and adjusted;

[0058] Step 8: Result judgment: if the adjustment effect meets the requirements, proceed to the next step; if the adjustment effect is not satisfactory, return to step 4 and recalculate the adjustment plan;

[0059] Step 9: Data recording and storage: record the data during the entire adjustment process, including the monitoring data of the pressure sensor 34, the adjustment plan, the feedback data of the actuator 3, etc., and store the data in the database for subsequent analysis and optimization;

[0060] In addition, users can monitor and operate the intelligent control system in real time through remote terminals or mobile devices. When necessary, users can manually adjust or intervene in the pre-camber of the steel box girder through remote operation;

[0061] In addition, the intelligent control system has a fault diagnosis function, which can automatically detect the fault status of the equipment and the pressure sensor 34. When a fault occurs, the system will notify the user through sound and light alarms or other means to handle it;

[0062] Through the above steps, the intelligent adjustment method can achieve accurate and efficient adjustment of the pre-arch of the steel box girder. This method has the advantages of high degree of automation, high adjustment accuracy, and strong adaptability, and can greatly improve the quality and efficiency of bridge construction.

[0063] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
