Description

Technical Field

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

[0002] In the current era of booming modern bridge construction, hanging basket construction technology has been widely used in various bridge projects due to its unique advantages. However, with the continuous expansion of bridge construction scale and the increasing sophistication of design standards, the limitations of traditional construction monitoring methods have become increasingly apparent, necessitating improvement.

[0003] Traditional stress monitoring of hanging baskets relies heavily on regular manual inspections using simple tools such as strain gauges. This method is not only time-consuming and labor-intensive, but also inefficient. Furthermore, the measurement results are greatly affected by human factors, making it difficult to guarantee the accuracy and real-time nature of the data. For example, during concrete pouring, the stress in the slings changes rapidly, which cannot be captured in time by manual measurements. Once the stress exceeds the safe range, it may lead to damage to the hanging basket structure or even cause serious safety accidents.

[0004] In the past, monitoring the tilt angle of hanging baskets often involved using basic equipment such as levels and obtaining tilt angle data through manual observation and reading. This method not only has limited accuracy, failing to meet the stringent precision requirements of modern bridge construction, but also increases the difficulty of measurement and reduces data reliability in complex construction environments, such as strong winds and intense sunlight. Furthermore, manual observation cannot achieve real-time monitoring and early warning; when sudden changes in the tilt angle of the hanging basket occur, it is difficult to detect and take timely measures, increasing construction risks. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a bridge construction hanging basket monitoring device, which aims to improve the problem that the measurement results in the prior art are greatly affected by human factors, making it difficult to guarantee the accuracy and real-time nature of the data.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a bridge construction formwork monitoring device, comprising a traveling track, a lower chord installed at the top of the traveling track, a front sliding support and a front inclined rod installed at one end of the top of the lower chord, an upper chord installed at one end of the front inclined rod, a rear inclined rod installed at the other end of the top of the lower chord, a front sling installed at one end of the upper chord, a sling stress monitoring mechanism installed inside the front sling for real-time monitoring of sling stress, and a formwork tilt angle monitoring mechanism installed at the top of the upper chord for real-time monitoring and early warning of the formwork tilt angle.

[0007] As a further description of the above technical solution:

[0008] The sling stress monitoring mechanism includes a stress sensor, which is installed at the bottom of the front sling. A protective shell is installed on one side of the outer wall of the stress sensor, and a compensation component is installed inside the protective shell.

[0010] The hanging basket tilt monitoring mechanism includes a tilt sensor, which is installed on one side of the outer wall of the upper chord, and the output end of the tilt sensor is electrically connected to an alarm component.

[0011] As a further description of the above technical solution:

[0012] The compensation component includes a heating wire, which is installed inside the protective housing.

[0013] As a further description of the above technical solution:

[0014] The alarm assembly includes an alarm and a flashing light, both of which are electrically connected to a tilt sensor.

[0015] As a further description of the above technical solution:

[0016] The protective shell is made of double-layer vacuum insulation material, with the inner layer being high-strength carbon fiber and the outer layer being ceramic fiber composite material.

[0017] As a further description of the above technical solution:

[0018] A heat-extending plate is installed on one side of the inner wall of the protective shell, and the heat-extending plate is in contact with the heating wire.

[0019] This utility model has the following beneficial effects:

[0020] 1. In this utility model, the sling stress monitoring mechanism of the device captures the stress changes of the sling at different construction stages based on the resistance strain effect. The double-layer vacuum insulation design of the protective shell not only effectively resists external forces such as collisions and compressions at the construction site with the high-strength carbon fiber material of the inner layer to prevent damage to the sensor, but also utilizes the good heat insulation performance of the ceramic fiber composite material of the outer layer to reduce external temperature interference. The heating wire and the heat extension plate in the compensation component work together to ensure that the sensor can be at a suitable working temperature in low-temperature environments, thereby improving the accuracy and stability of stress monitoring.

[0021] 2. In this utility model, the protective shell uses double-layer vacuum insulation material, and the heating wire and heat extension plate design of the compensation component enable the sling stress monitoring mechanism to adapt to different construction environment temperatures. Whether in scorching heat or freezing cold, the stress sensor can operate stably. This adaptability to environmental temperature reduces monitoring errors and equipment failures caused by environmental factors, improving the reliability and service life of the monitoring device. Simultaneously, the stable operation of the hanging basket tilt angle monitoring mechanism is unaffected by environmental factors, consistently providing accurate monitoring and early warning of the hanging basket tilt angle, ensuring safe and smooth construction in various complex environments.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figure 1-3 An embodiment of this utility model provides a bridge construction hanging basket monitoring device, including a traveling track 1, a lower chord 2 installed on the top of the traveling track 1, a front sliding support 3 and a front inclined rod 4 installed at one end of the top of the lower chord 2, an upper chord 6 installed at one end of the front inclined rod 4, a rear inclined rod 5 installed at the other end of the top of the lower chord 2, a front sling 7 installed at one end of the upper chord 6, a sling stress monitoring mechanism installed inside the front sling 7 for real-time monitoring of sling stress, and a hanging basket tilt angle monitoring mechanism installed at the top of the upper chord 6 for real-time monitoring and early warning of the hanging basket tilt angle.

[0029] The sling stress monitoring mechanism includes a stress sensor 8, which is installed at the bottom of the front sling 7. A protective shell 9 is installed on one side of the outer wall of the stress sensor 8, and a compensation component is installed inside the protective shell 9.

[0030] The compensation assembly includes a heating wire 11, which is installed inside the protective housing 9;

[0031] The protective shell 9 is made of double-layer vacuum insulation material, with the inner layer 13 being high-strength carbon fiber material and the outer layer 14 being ceramic fiber composite material.

[0032] A heat-extending plate 15 is installed on one side of the inner wall of the protective shell 9, and the heat-extending plate 15 is in contact with the heating wire 11;

[0033] Specifically, the stress sensor 8, as the core component, utilizes the resistance strain effect to sense stress changes in the front sling 7. When the sling deforms under stress, the resistance value inside the stress sensor 8 changes accordingly. By accurately measuring the change in resistance value, the circuit converts it into a corresponding stress value. Due to the complex environment and large temperature fluctuations at the construction site, the protective shell 9 and its internal compensation components play a crucial role in ensuring the measurement accuracy of the stress sensor 8. The protective shell 9 uses double-layer vacuum insulation material. The high-strength carbon fiber material of the inner layer 13 ensures that the protective shell 9 has good mechanical strength and can withstand external impacts such as collisions and compressions that may occur at the construction site, protecting the internal stress sensor 8. The ceramic fiber composite material of the outer layer 14 has excellent heat insulation performance, effectively reducing the influence of the external ambient temperature on the sensor. When the ambient temperature is too low, the heating wire 11 in the compensation component begins to function. After the heating wire 11 is energized, it generates heat, which is evenly transferred to the interior of the protective shell 9 through the heat extension plate 15 attached to it, thereby increasing the temperature around the stress sensor 8. The presence of the heating plate 15 allows the heat generated by the heating wire 11 to be distributed more efficiently and evenly, avoiding local overheating or overcooling, and ensuring that the stress sensor 8 is always within a suitable operating temperature range, thereby guaranteeing the accuracy and stability of its measured stress data.

[0034] The hanging basket tilt monitoring mechanism includes a tilt sensor 10, which is installed on one side of the outer wall of the upper chord 6. The output end of the tilt sensor 10 is electrically connected to an alarm component.

[0035] The alarm assembly includes an alarm 12 and a flashing light 16, both of which are electrically connected to the tilt sensor 10.

[0036] Specifically, the tilt sensor 10 utilizes the principles of gravity sensing and inertial measurement to detect changes in the tilt angle of the upper chord 6 in real time. When the hanging basket tilts, the sensitive element inside the tilt sensor 10 undergoes corresponding physical changes due to gravity. These changes are converted into electrical signals. Once the tilt sensor 10 detects that the tilt angle of the hanging basket exceeds a preset safety threshold, it immediately transmits the electrical signal to the alarm component. Upon receiving the signal, the alarm 12 in the alarm component quickly emits a loud audible alarm to attract the attention of personnel at the construction site. Simultaneously, the flashing light 16 is also triggered, flashing at a high frequency to further enhance the warning effect through a striking visual signal. In the noisy and busy construction site, the dual alarm of sound and light ensures that construction personnel notice abnormalities in the tilt angle of the hanging basket immediately and take appropriate measures, such as suspending construction and adjusting the posture of the hanging basket, thereby effectively avoiding safety accidents caused by excessive tilting of the hanging basket and ensuring the safety and smooth progress of bridge construction.

[0037] Working Principle: The bridge construction hanging basket monitoring device ensures construction safety through the coordinated operation of the sling stress monitoring mechanism and the hanging basket tilt angle monitoring mechanism. In the sling stress monitoring mechanism, the stress sensor 8 is based on the resistance strain effect. When the front sling 7 under load deforms, its internal resistance changes, which is converted into a stress value by the circuit. Given the large temperature fluctuations at the construction site, the protective shell 9 plays an important role. The inner layer 13 of the double-layer vacuum insulation material is made of high-strength carbon fiber to resist external impacts and protect the stress sensor 8, while the outer layer 14 is made of ceramic fiber composite material to isolate the influence of external temperature. When the ambient temperature is too low, the heating wire 11 of the compensation component is energized to generate heat. The heat is evenly transferred to the inside of the protective shell 9 through the heat extension plate 15, ensuring that the stress sensor 8 is at a suitable working temperature and ensuring accurate and stable measurement data. In the hanging basket tilt angle monitoring mechanism, the tilt sensor 10 senses the change in the tilt angle of the upper chord 6 in real time based on the principles of gravity sensing and inertial measurement, converting the physical changes caused by gravity to the sensitive element into electrical signals. Once the inclination angle of the hanging basket exceeds the safety threshold, an electrical signal is transmitted to the alarm component. The alarm 12 then emits a loud sound alarm, and the flashing light 16 flashes at a high frequency. Through the dual warning of sound and light, construction personnel can detect the problem in time and take measures to avoid safety accidents caused by excessive tilting of the hanging basket, thus ensuring the smooth progress of bridge construction.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
