Abstract
Description
Technical Field
[0001] This utility model relates to the field of bridge construction technology, and in particular to a real-time monitoring device for the displacement of a hanging basket in bridge construction. Background Technology
[0002] Bridges, as a key component of modern transportation infrastructure, play an irreplaceable role in connecting different regions and promoting economic development and social exchange. With the continuous expansion of bridge construction scale and the increasing technical difficulty, the construction of long-span bridges is becoming increasingly common. Bridge construction technology, due to its efficiency and flexibility, has become the preferred construction method for many bridge projects. During the cantilever construction process, accurately controlling the displacement changes of the cantilever formwork is crucial to ensuring construction safety and the quality of the bridge structure.
[0003] However, early monitoring systems often lacked comprehensive consideration of environmental factors. Bridge construction is typically carried out in open environments, and changes in environmental factors such as temperature, humidity, and wind can significantly affect the displacement of the formwork. For example, drastic temperature changes can cause thermal expansion and contraction of the formwork's structural materials, leading to changes in its displacement; strong winds can cause significant swaying, increasing the difficulty of displacement monitoring. However, traditional monitoring devices did not effectively compensate for and correct for these environmental factors, resulting in measurement results that could not accurately reflect the actual displacement of the formwork and mislead construction decisions. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a real-time monitoring device for the displacement of a hanging basket in bridge construction. It aims to improve the problem that traditional monitoring devices in the prior art do not effectively compensate and correct for these environmental factors, making the measurement results unable to truly reflect the actual displacement of the hanging basket.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a real-time displacement monitoring device for a bridge construction formwork, comprising a traveling track, a displacement monitoring mechanism installed on one side of the outer wall of the traveling track for monitoring displacement changes of the formwork, a lower chord fixedly connected to one side of the outer wall of the traveling track, a front sliding support fixedly connected to one side of the outer wall of the lower chord, a front inclined rod fixedly connected to one end of the lower chord, a rear inclined rod fixedly connected to the other end of the lower chord, an upper chord fixedly connected to the top of the front and rear inclined rods, and an environmental mechanism installed on one side of the outer wall of the upper chord for real-time monitoring of the bridge construction environment.
[0006] As a further description of the above technical solution:
[0007] The displacement monitoring mechanism includes a displacement sensor, which is installed on one side of the outer wall of the lower chord, and a temperature compensation component is installed on one side of the outer wall of the displacement sensor.
[0008] As a further description of the above technical solution:
[0009] The environmental mechanism includes a monitoring camera, which is mounted on one side of the outer wall of the upper chord. An extension frame is installed on one side of the outer wall of the monitoring camera, and evenly distributed heat dissipation fins are installed inside the extension frame.
[0010] As a further description of the above technical solution:
[0011] The temperature compensation component includes a protective shell, which is fixedly connected to one side of the outer wall of the displacement sensor. A semiconductor heating element is installed inside the protective shell, and a convection ring is installed on the outer wall of the protective shell.
[0012] As a further description of the above technical solution:
[0013] Ventilation holes are provided on both sides of the outer wall of the convection ring, and auxiliary patterns are provided inside the convection ring.
[0014] As a further description of the above technical solution:
[0015] The outer wall of the heat dissipation fins has evenly distributed grooves.
[0016] As a further description of the above technical solution:
[0017] The convection ring has a circular cross-section.
[0018] This utility model has the following beneficial effects:
[0019] In this invention, the displacement sensor emits a laser beam and receives the reflected light. Based on the laser's round-trip time, it calculates the distance change to the target reflected by the basket, thus obtaining a precise displacement value. Furthermore, the temperature compensation component of the displacement sensor utilizes the Peltier effect to maintain a suitable operating temperature, ensuring stable operation under different temperature conditions and reducing measurement errors caused by temperature fluctuations.
[0020] In this invention, the heat dissipation fins within the extended frame significantly increase the surface area through the concave texture of their outer wall, effectively improving heat dissipation efficiency. When the monitoring camera generates heat during operation, the heat dissipation fins can quickly dissipate the heat into the surrounding air, ensuring that the camera will not overheat and affect shooting quality and stability during long-term continuous operation.

[0026] 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.
[0027] Reference Figures 1-3 An embodiment of this utility model provides a real-time displacement monitoring device for a bridge construction formwork, comprising a travel track 1, a displacement monitoring mechanism installed on one side of the outer wall of the travel track 1 for monitoring the displacement changes of the formwork, a lower chord 2 fixedly connected to one side of the outer wall of the travel track 1, a front sliding support 3 fixedly connected to one side of the outer wall of the lower chord 2, a front inclined rod 4 fixedly connected to one end of the lower chord 2, a rear inclined rod 5 fixedly connected to the other end of the lower chord 2, an upper chord 6 fixedly connected to the top of the front inclined rod 4 and the rear inclined rod 5, and an environmental mechanism installed on one side of the outer wall of the upper chord 6 for real-time monitoring of the bridge construction environment;
[0028] The displacement monitoring mechanism includes a displacement sensor 7, which is installed on one side of the outer wall of the lower chord 2. A temperature compensation component is installed on one side of the outer wall of the displacement sensor 7.
[0029] The temperature compensation component includes a protective shell 11, which is fixedly connected to one side of the outer wall of the displacement sensor 7. A semiconductor heating element 12 is installed inside the protective shell 11, and a convection ring 13 is installed on the outer wall of the protective shell 11.
[0030] Ventilation holes 14 are provided on both sides of the outer wall of the convection ring 13, and auxiliary patterns 15 are provided inside the convection ring 13.
[0031] The cross-section of the convection ring 13 is circular;
[0032] Specifically, the core component of the displacement monitoring mechanism is the displacement sensor 7, which is installed on one side of the outer wall of the lower chord 2 to capture the displacement changes of the hanging basket during movement. When the hanging basket moves, the displacement sensor 7 converts the displacement of the hanging basket into an electrical signal output through the internal sensing element. The protective shell 11 wraps the displacement sensor 7, which not only protects the sensor from external mechanical damage, but also creates a relatively closed environment for internal temperature regulation. The semiconductor heating element 12 inside the protective shell 11 is activated when the ambient temperature is lower than the optimal operating temperature of the displacement sensor 7. The semiconductor heating element 12 utilizes the Peltier effect to generate heat when energized, raising the internal temperature of the protective shell 11 and keeping the sensor within a suitable operating temperature range. When the ambient temperature is too high, the convection ring 13 comes into play. The ventilation holes 14 on both sides of the outer wall of the convection ring 13 allow air to circulate inside and outside the convection ring 13. Since the cross-section of the convection ring 13 is circular, this shape helps the air to flow more smoothly. The auxiliary textures 15 inside the convection ring 13 increase the contact area and friction between the air and the inner wall of the convection ring 13, further promoting air convection and accelerating heat dissipation. Air enters through the ventilation holes 14, carries away the heat from the surface of the protective shell 11, and then exits, thereby cooling the displacement sensor 7 and ensuring that it can stably and accurately measure the displacement of the basket under different temperature environments.
[0033] The environmental mechanism includes a monitoring camera 8, which is installed on one side of the outer wall of the upper chord 6. An extension frame 9 is installed on one side of the outer wall of the monitoring camera 8, and evenly distributed heat dissipation fins 10 are installed inside the extension frame 9.
[0034] The outer wall of the heat dissipation fin 10 is provided with evenly distributed grooves 16;
[0035] Specifically, the environmental monitoring camera 8 is installed on one side of the outer wall of the upper chord 6, enabling real-time imaging of the bridge construction site. These images allow construction personnel to intuitively understand the site conditions, such as the location of the formwork, the operating status of surrounding construction equipment, and worker operations. This helps to promptly detect abnormalities during construction, such as the risk of collision between the formwork and other objects, and whether construction operations are standardized. The extension frame 9 installed on one side of the outer wall of the monitoring camera 8 primarily provides installation space for the internal heat dissipation fins 10. The heat dissipation fins 10 are evenly distributed inside the extension frame 9, and the evenly distributed grooves 16 on its outer wall increase the surface area of the heat dissipation fins 10. When the monitoring camera 8 generates heat, the heat is transferred to the heat dissipation fins 10. Because the grooves 16 increase the surface area and the contact area with air, the heat exchange efficiency is improved. When air flows through the heat dissipation fins 10, it can more effectively absorb and carry away heat, thereby achieving heat dissipation and cooling of the monitoring camera 8. This ensures that the monitoring camera 8 will not overheat and affect the image quality and stability during long-term continuous operation, guaranteeing that it can continuously and stably monitor the bridge construction environment in real time.
[0036] Working principle: The traveling track 1 guides the movement of the hanging basket. One side of its outer wall is connected to the lower chord 2. The front sliding support 3 on the lower chord 2 assists in the smooth movement of the hanging basket. The front diagonal bar 4 and the rear diagonal bar 5, together with the upper chord 6, form a stable triangular structure, providing stable support for the entire device. For displacement monitoring, the displacement sensor 7, installed on one side of the outer wall of the lower chord 2, emits a laser beam that is reflected by the hanging basket and the target. The displacement of the hanging basket is calculated based on the laser's round-trip time and the distance change, and then converted into an electrical signal output. A protective shell 11 on one side of the outer wall of the displacement sensor 7 protects it from mechanical damage. Inside the protective shell 11, a semiconductor heating element 12 heats up using the Peltier effect when the ambient temperature is below the optimal operating temperature, raising the internal temperature. When the temperature is too high, the convection ring 13 comes into play. Ventilation holes 14 on both sides of its outer wall create air convection. The circular cross-section facilitates airflow, and the internal auxiliary texture 15 increases the contact area and friction between the air and the inner wall, accelerating heat dissipation and cooling. In terms of environmental monitoring, a monitoring camera 8 installed on one side of the outer wall of the upper chord 6 captures real-time images of the construction site, facilitating the monitoring personnel's understanding of the situation. Evenly distributed heat dissipation fins 10 within the extended frame 9 on one side of the outer wall of the monitoring camera 8, with increased surface area through the outer wall grooves 16, ensure that heat generated by the camera is transferred to the fins. Airflow efficiently absorbs and carries away this heat, ensuring continuous and stable camera operation and enabling effective monitoring of the construction environment. Through the coordinated operation of all components, comprehensive monitoring of the displacement of the bridge construction formwork and the environment is achieved.
