Traditional construction hanging baskets often have fixed structures and are difficult to adapt to the construction needs of bridges of different widths, which limits construction efficiency and flexibility. In addition, they lack stability during the lifting process, which can easily lead to safety accidents. In addition, there is a lack of comprehensive and effective safety monitoring methods during bridge construction, making it difficult to accurately grasp the state changes of the bridge structure during the construction process in real time. For example, factors such as wind, temperature, humidity, and construction loads will affect bridge columns and bridge panels, which may cause structural deformation, tilt, or even damage. If they are not monitored in time and appropriate measures are not taken, the lives of construction workers and the overall quality and service life of the bridge will be seriously threatened.

[0018] Real-time safety warning and decision support: The data collected by the monitoring system can be transmitted in real time to the monitoring center at the construction site or the terminal equipment of relevant technicians. Once the monitoring data exceeds the preset safety threshold, the system can immediately issue a warning signal to remind the construction personnel to take corresponding protective measures or adjust the construction plan. At the same time, these accurate data also provide a scientific decision-making basis for bridge engineers and technicians, helping them to timely analyze the causes and extent of structural safety hazards, formulate reasonable repair or reinforcement strategies, ensure that bridge construction is always carried out within a safe and controllable range, effectively prevent the occurrence of major safety accidents, and ensure the construction quality and long-term service life of the bridge.

Bridge detection system installation: Select a suitable location on the top of the bridge column to install anemometer, inclinometer and strain gauge A; use professional mounting brackets to fix these devices on the bridge column and perform precise calibration and debugging to ensure that they can accurately measure wind speed, wind direction, inclination angle and strain data of the bridge column; Install a static level and strain gauge B at the corresponding position below the bridge column, and also firmly install and accurately debug them so that they can effectively measure the vertical displacement and strain between the bridge columns; 6. System debugging and trial operation: Test the wire rope reeling and unreeling mechanism of the mobile walking vehicle, operate its rising, falling and stopping actions, check whether the lifting and lowering of the hanging basket is stable and smooth, whether the wire rope support roller plays an effective role in reducing friction, and observe whether there is any abnormal noise, vibration or jamming during the operation of the entire device; Start the bridge inspection system, conduct data collection tests on the anemometer, inclinometer, strain gauge and static level, check whether each monitoring device can work normally, whether the collected data is accurate and stable, and compare and analyze the test data with the actual environmental parameters or standard data. If there is any deviation, make timely adjustments and calibrations; During the trial operation, professionals were arranged to conduct a comprehensive inspection of the entire bridge construction safety device and system, including the connection tightness of each component, the operating status of the equipment, the stability of data transmission, etc., to ensure that the system is in the best working condition before it is officially put into use; 7. Formal use and maintenance: During the bridge construction process, the operator controls the steel rope reeling and unreeling mechanism of the mobile traveling vehicle according to the construction requirements to lift the combined bridge construction hanging basket to the designated construction position under the bridge deck, and the construction personnel carry out various construction operations on the bottom surface of the bridge in the hanging basket; The bridge detection system monitors various parameters of bridge columns and bridge panels in real time, such as wind speed, wind direction, inclination angle, strain and vertical displacement, and transmits the data to the monitoring center at the construction site or the mobile terminal devices of relevant technicians; arranges regular maintenance work, lubricates, inspects and tightens the mechanical parts of the mobile traveling vehicle at regular intervals, conducts appearance inspection and structural integrity assessment of the hanging basket body, performs precision calibration and data storage cleaning on the monitoring equipment, and replaces damaged or aging parts and equipment in time to ensure that the bridge construction safety devices and systems operate continuously, stably and efficiently throughout the entire bridge construction cycle, providing reliable protection for bridge construction safety.
