Description

Technical Field

[0001] This utility model relates to the field of bridge construction monitoring technology, and in particular to an automatic monitoring device for bridge rotation construction. Background Technology

[0002] In bridge construction, rotation construction is a common and important method. When a bridge crosses existing lines (such as railways and highways), rivers, or other obstacles, rotation construction technology is often used to minimize the impact on existing traffic or the environment. This involves first pouring or assembling the bridge structure at a non-crossing location, and then rotating the bridge to the designed position using a rotation system.

[0003] However, numerous risk factors exist during bridge rotation construction. For example, deviations in the bridge's posture may lead to uneven structural stress, affecting its stability and safety; improper displacement control may prevent the bridge from accurately reaching its designed position, requiring additional adjustments and corrections; and stress changes at the connection points between the piers and the bridge may exceed the design range, potentially causing structural damage and serious engineering accidents. Therefore, to ensure the safe and smooth progress of bridge rotation construction, real-time and accurate monitoring of parameters such as the bridge's posture, displacement, and stress is necessary. Traditional monitoring methods often rely on manual measurement, which suffers from low accuracy and poor real-time performance, failing to meet the requirements of modern bridge rotation construction. Utility Model Content

[0004] The purpose of this invention is to provide an automatic monitoring device for bridge rotation construction. This automatic monitoring device for bridge rotation construction, through structures such as posture, displacement, stress monitoring units and counterweight components, can monitor construction parameters in real time, improve construction safety and accuracy, realize automated monitoring, and facilitate data analysis and decision-making to ensure smooth construction.

[0005] To achieve the above objectives, this utility model provides an automatic monitoring device for bridge rotation construction, including a data acquisition module and a control center. The data acquisition module is electrically connected to the control center. The data acquisition module includes an attitude monitoring unit, a displacement monitoring unit, and a stress monitoring unit. The attitude monitoring unit includes a counterweight component and an inclination monitoring component.

[0006] Preferably, the counterweight assembly includes a counterweight block and a counterweight trolley. The counterweight block and the counterweight trolley are fixedly connected. Six wheels are installed on the top of the counterweight trolley. The wheels are placed in the first groove at the bottom of the bridge. A sliding block is installed in the middle of the wheel. The sliding block has an inverted T-shaped structure and is placed in the second groove. The second groove and the sliding block cooperate and are slidably connected.

[0007] Preferably, a lead screw runs through the slider, one end of which is connected to a motor, and the other end of which is rotatably connected to a limit plate. The motor is fixed to the bottom surface of the bridge.

[0008] Preferably, the tilt detection assembly consists of eight groups, six of which are evenly distributed on the upper turntable, and the other two are placed in the middle of the bridge. The tilt detection assembly includes a tilt sensor and a connecting frame. The connecting frame is fixedly installed on the side wall of the upper turntable by bolts. The other end of the connecting frame extends into the bottom of the upper turntable, and the tilt sensor is fixedly connected to the end of the connecting frame.

[0009] Preferably, the displacement monitoring unit includes a displacement sensor.

[0010] Preferably, the stress monitoring unit includes a stress sensor, which is installed at the connection between the pier and the bridge.

[0011] Therefore, the automatic monitoring device for bridge rotation construction described above has the following beneficial effects:

[0012] (1) The attitude monitoring unit can monitor the tilt angle of the bridge in real time. Once an abnormal attitude is detected, measures can be taken in time to adjust it to avoid safety accidents such as structural instability caused by excessive bridge tilt.

[0013] (2) The real-time monitoring of bridge displacement by the displacement monitoring unit can ensure that the bridge rotates accurately to the designated position according to the design requirements, and prevent safety problems such as collisions caused by excessive displacement deviation.

[0014] (3) The stress monitoring unit can monitor the stress at the connection between the pier and the bridge, and can detect stress concentration or abnormal changes in a timely manner, provide early warning of the risk of structural damage, and ensure the safety of the bridge structure.

[0015] (4) The data acquisition module is electrically connected to the control center, which can automatically collect data such as the bridge's attitude, displacement and stress, and transmit them to the control center for processing and analysis. This reduces manual intervention and improves monitoring efficiency and accuracy. The control center can store and analyze the collected data and generate detailed monitoring reports to provide decision-making basis for construction management personnel, which helps to adjust the construction plan in a timely manner and ensure the smooth progress of construction.

[0024] Example 1

[0025] like Figures 1 to 3 As shown, this utility model provides an automatic monitoring device for bridge rotation construction, including a data acquisition module and a control center. The data acquisition module is used to collect various data information during the bridge rotation construction process, providing data support to the control center for monitoring and controlling the bridge rotation construction. The control center is used to receive and process the data transmitted from the data acquisition module, and through analysis and processing of this data, realizes automated monitoring and control of the bridge rotation construction. The data acquisition module is electrically connected to the control center and includes an attitude monitoring unit, a displacement monitoring unit, and a stress monitoring unit. The attitude monitoring unit includes a counterweight component and an inclination angle monitoring component. The attitude detection unit is used to monitor the attitude information of the bridge 1, including the inclination angle of the bridge 1, to determine whether the attitude of the bridge 1 is normal during the rotation construction process.

[0026] The counterweight assembly includes a counterweight block 2 and a counterweight trolley 3. The counterweight block 2 and the counterweight trolley 3 are fixedly connected. The counterweight block 2 provides a certain amount of counterweight for the rotation construction of bridge 1, which helps to adjust the center of gravity and stability of bridge 1. The counterweight trolley 3 is used to carry the counterweight block 2. It is placed in the first slide groove at the bottom of bridge 1 by means of a rotating wheel 5 on the top. It can move along the first slide groove under the drive of motor 8, thereby adjusting the position of the counterweight and further optimizing the attitude and stability of bridge 1. The counterweight trolley 3 is equipped with six rotating wheels 5 on the top. The rotating wheels 5 are placed in the first slide groove at the bottom of bridge 1. The installation of the rotating wheels 5 allows the counterweight trolley 3 to slide flexibly in the first slide groove, realizing the change of the counterweight position. A sliding block 7 is installed in the middle of the rotating wheel 5. The sliding block 7 has an inverted T-shaped structure and is placed in a second slide groove. The second slide groove cooperates with and slides with the sliding block 7. The sliding block 7 plays the role of guiding and restricting the movement direction of the counterweight trolley 3, ensuring that the counterweight trolley 3 moves in a predetermined direction. A lead screw 6 runs through the slider and is connected to a motor 8. Driven by the motor 8, the lead screw 6 rotates, causing the sliding block 7 and the counterweight carriage 3 to move along the axial direction of the lead screw 6, thus achieving precise adjustment of the counterweight position. The motor 8 provides power for the rotation of the lead screw 6, thereby driving the movement of the counterweight carriage 3 and achieving automatic adjustment of the counterweight position. The other end of the lead screw 6 is rotatably connected to a limiting plate 9. The motor 8 is fixed to the bottom surface of the bridge 1, and the limiting plate 9 serves to limit and support the rotation of the lead screw 6, preventing axial movement during rotation.

[0027] The tilt detection assembly consists of eight sets, six of which are evenly distributed on the upper turntable 4, and the other two are located in the middle of the bridge 1. Each tilt detection assembly includes a tilt sensor 10 and a connecting frame 11. The connecting frame 11 is bolted to the side wall of the upper turntable 4, with one end extending into the bottom of the upper turntable 4. The tilt sensor 10 is fixedly connected to the end of the connecting frame 11. The tilt sensor 10 detects the tilt angle of the bridge 1, converts the detected angle information into an electrical signal, and transmits it to the control center for real-time monitoring of the bridge 1's tilt status. The connecting frame 11, bolted to the side wall of the upper turntable 4, with its other end extending into the bottom of the upper turntable 4, serves to fix and support the tilt sensor 10, ensuring that the tilt sensor 10 can accurately detect the tilt angle of the bridge 1.

[0028] The displacement monitoring unit includes displacement sensors, which are installed using existing technologies and whose structure is common knowledge. These sensors monitor the displacement of Bridge 1 during the rotation construction process, including horizontal and vertical displacement, providing data for displacement control during construction. The stress monitoring unit includes stress sensors, which are installed at the connection between the pier and Bridge 1. These stress sensors monitor stress changes at this connection point during the rotation construction process, promptly detecting potential stress concentrations or anomalies to ensure the structural safety of Bridge 1. The stress sensors are installed using existing, commonly known methods.

[0029] When the automatic monitoring device for bridge rotation construction provided by this utility model is used, the counterweight component in the attitude monitoring unit is driven by the motor 8 to drive the lead screw 6 to move the counterweight trolley 3 in the slide groove at the bottom of the bridge 1 to adjust the attitude of the bridge 1. The tilt sensor 10 detects the tilt angle of the bridge 1. The displacement sensor of the displacement monitoring unit monitors the displacement of the bridge 1, and the stress sensor of the stress monitoring unit monitors the stress at the connection between the pier and the bridge 1. Each monitoring unit converts the collected attitude, displacement, stress and other information into electrical signals and transmits them to the control center. The control center processes and analyzes the signals into specific data, compares them with preset thresholds and parameters to judge the construction status. If the parameters are abnormal, an alarm is issued and the equipment is controlled to adjust to ensure safe and smooth construction.

[0030] Therefore, this utility model adopts the above-mentioned automatic monitoring device for bridge rotation construction. This automatic monitoring device for bridge rotation construction, through structures such as posture, displacement, stress monitoring units and counterweight components, can monitor construction parameters in real time, improve construction safety and accuracy, realize automated monitoring, and facilitate data analysis and decision-making to ensure smooth construction.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
