In the actual construction environment, the hanging basket faces various complex environmental conditions, such as high temperature, high humidity, strong wind, sand and dust, etc. The traditional stress sensor is easy to have measurement error, damage and even failure in these harsh environments. For example, in high temperature environment, the electronic components of the sensor may be overheated and the performance may be degraded, resulting in inaccurate measurement data; in the area with more sand and dust, sand and dust particles are easy to enter the inside of the sensor, wear the sensitive parts, and shorten the service life of the sensor. These problems not only affect the reliability of stress monitoring, but also increase the cost of equipment maintenance and replacement, and seriously affect the construction progress.

The data collected by the sensor often needs to be analyzed and processed manually, which is low in efficiency and easy to have human error. Moreover, when the stress is abnormal, there is no timely and effective early warning mechanism to inform the construction personnel to take corresponding measures in the first time. For example, in some cases, even if the sensor has monitored that the stress of the main truss exceeds the safety threshold, due to the untimely data processing or imperfect early warning system, the construction personnel cannot know this situation in time and continue the construction, which eventually leads to serious damage of the bridge structure.

Specific implementation

[0027] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the range of protection of the utility model.

[0028] Reference Figs. 1-3The utility model provides an embodiment: a bridge hanging basket with stress monitoring device, including walking track 1, the outer wall one side of walking track 1 is installed with lower chord 2, the top one end of lower chord 2 is installed with rear anchor beam 3, the top of rear anchor beam 3 is installed with rear anchor stress monitoring mechanism, it is used for to the anchoring force of rear anchor beam 3 carries out real -time monitoring, the top other end of lower chord 2 is installed with front sliding support 4, and the top of front sliding support 4 is installed with vertical pole 5 and front inclined pole 6 respectively, and one end of vertical pole 5 is installed with rear chord 7, and the top of rear chord 7 is provided with main truss stress monitoring mechanism.

[0029] Rear anchor stress monitoring mechanism includes anchoring force sensor 8, and anchoring force sensor 8 is installed at the top one side of rear anchor beam 3, and the outer wall one side of anchoring force sensor 8 is installed with temperature control box 9, and the inside of temperature control box 9 is provided with compensation component;

[0030] Compensation component includes temperature sensor 11, and temperature sensor 11 is installed at the outer wall one side of anchoring force sensor 8, and the output of temperature sensor 11 is electrically connected with semiconductor refrigeration piece 12 and resistance wire 13 respectively;

[0031] The outer wall of temperature control box 9 is installed with exhaust fan 14, and the output of exhaust fan 14 is communicated with diffusion plate 15;

[0032] The outer wall one side of diffusion plate 15 is installed with dust screen 17;

[0033] Specifically, the anchoring force sensor 8 is installed on one side of the top of the rear anchorage beam 3, and its working principle is based on the piezoelectric effect or the resistance strain gauge principle. When the anchoring force of the rear anchorage beam 3 changes, the sensitive element inside the sensor will produce a corresponding physical deformation, which in turn causes a change in the electrical parameter, such as the piezoelectric sensor will produce a change in the amount of electric charge proportional to the anchoring force, and the resistance strain gauge sensor will cause the resistance value to change. By measuring the change of these electrical parameters, the anchoring force of the rear anchorage beam 3 can be accurately calculated and converted into an electrical signal output. The temperature control box 9 is installed on one side of the outer wall of the anchoring force sensor 8, which provides a stable working temperature environment for the sensor. The temperature sensor 11 in the compensation assembly monitors the temperature around the anchoring force sensor 8 in real time. When the temperature sensor 11 detects that the temperature is higher than the preset suitable working temperature range, it will send a signal to the semiconductor refrigeration sheet 12. The semiconductor refrigeration sheet 12 uses the Peltier effect to absorb heat on one end and release heat on the other end under the action of electric current, thereby reducing the temperature around the sensor. Conversely, when the temperature is lower than the suitable range, the temperature sensor 11 sends a signal to the resistance wire 13, which generates heat after being electrified to heat the environment around the sensor, thereby maintaining the anchoring force sensor 8 at the best working temperature state at all times and ensuring its measurement accuracy is not affected by temperature fluctuations. The exhaust fan 14 on the outer wall of the temperature control box 9 plays an important role in the temperature control process. When the semiconductor refrigeration sheet 12 works to cool, the exhaust fan 14 starts to quickly exhaust the heat absorbed in the temperature control box 9. The exhaust heat air is diffused through the diffusion plate 15 connected to the output end of the exhaust fan 14, which can make the heat air more evenly diffuse to the surrounding environment, improving the heat dissipation efficiency. At the same time, the dust screen 17 on one side of the outer wall of the diffusion plate 15 can effectively prevent dust from entering the inside of the temperature control box 9, preventing dust accumulation from affecting the normal work of the sensor and other components, and ensuring the stability and reliability of the entire rear anchorage stress monitoring mechanism.

[0034] The main truss stress monitoring mechanism includes a stress sensor 10, which is installed on one side of the outer wall of the rear chord 7. The output end of the stress sensor 10 is electrically connected with an alarm component;

[0035] The alarm component includes a buzzer 16, which is electrically connected with the stress sensor 10;

[0036] Specifically, the stress sensor 10 is installed on the outer wall of the rear chord 7 and monitors the stress change based on the physical properties of the material. When the main truss generates stress due to construction load, temperature change, etc., the rear chord 7 deforms slightly, the sensitive element of the stress sensor 10 deforms accordingly, causing changes in the internal electrical properties of the sensor, and then outputting an electrical signal related to the stress size, and the alarm component is composed of a buzzer 16. When the stress sensor 10 monitors that the stress value of the main truss exceeds the preset safety threshold, it will immediately transmit the electrical signal to the buzzer 16. After the buzzer 16 receives the signal, the internal electromagnetic coil drives the diaphragm to vibrate, and a loud sound alarm is emitted. In the noisy bridge construction site, this alarm sound can attract the attention of the construction personnel, reminding them that the main truss stress is abnormal and needs to be checked and handled in time, such as suspending construction, detecting the structure of the main truss, etc., so as to avoid accidents such as structural damage caused by excessive stress of the main truss, and ensure the safety of bridge construction.

[0037] Working principle: In the bridge hanging basket with stress monitoring device, all components work closely together to effectively monitor the stress of the rear anchor beam 3 and the main truss and ensure safety. The anchoring force sensor 8 is installed on one side of the top of the rear anchor beam 3, and based on the piezoelectric effect or resistance strain gauge principle, when the anchoring force of the rear anchor beam 3 changes, the internal sensitive element produces physical deformation, causing changes in electrical parameters, such as the piezoelectric sensor generating a proportional change in the amount of electric charge to the anchoring force, and the resistance strain gauge sensor changing the resistance value. The anchoring force is calculated and converted into an electrical signal output by measuring these changes. The temperature control box 9 is installed on one side of the outer wall of the sensor, and the temperature sensor 11 in the compensation component inside the temperature control box 9 monitors the temperature around the sensor in real time. When the temperature is higher than the appropriate range, a signal is sent to the semiconductor refrigerating fin 12 to cool and refrigerate by using the Peltier effect; when the temperature is lower than the appropriate range, a signal is sent to the resistance wire 13 to heat. The exhaust fan 14 on the outer wall of the temperature control box 9 starts when the semiconductor refrigerating fin 12 works, and the absorbed heat is discharged through the diffusion plate 15, which evenly diffuses the hot air to improve the heat dissipation efficiency. The dust screen 17 on the outer wall blocks dust from entering, ensuring stable and reliable operation of the mechanism. The stress sensor 10 is installed on one side of the outer wall of the rear chord 7, and based on the physical properties of the material, when the main truss generates stress due to construction load, temperature change, etc., causing the rear chord 7 to deform slightly, the sensor sensitive element deforms accordingly, changes the internal electrical properties, and outputs an electrical signal related to the stress size. When the stress value exceeds the preset safety threshold, the signal is transmitted to the alarm component composed of a buzzer 16, and the buzzer 16 internally electromagnetic coil drives the diaphragm to vibrate and emit an alarm sound, reminding the construction personnel that the main truss stress is abnormal, and taking timely measures to ensure construction safety.
