Description

TECHNICAL FIELD

[0001] The utility model relates to bridge engineering technical field especially relates to bridge construction hanging basket safety protection system device. BACKGROUND

[0002] In modern bridge engineering construction, the hanging basket construction technology is widely used in the cantilever pouring construction of large-span bridges. With the continuous expansion of the scale of bridge construction and the increasing complexity of the construction environment, the safety protection requirements for the bridge construction hanging basket are also increasingly high.

[0003] The traditional bridge construction hanging basket has many limitations in safety protection. In displacement monitoring, it often relies on manual periodic measurement or relatively simple monitoring equipment. Manual measurement is difficult to achieve real-time and accurate monitoring. For example, in large bridge construction, the displacement of the hanging basket needs to be checked frequently, and manual measurement requires construction personnel to reach a specific location each time to measure using measuring instruments (such as total stations, levels, etc.). It is difficult to meet the requirements of modern bridge construction for displacement monitoring accuracy. Once the displacement of the hanging basket exceeds the safe range, it may cause the hanging basket structure to be unstable, affecting the quality of bridge construction, and even causing serious safety accidents such as hanging basket falling and bridge structure damage. For inclination monitoring, the traditional method also lacks effective real-time monitoring means. During the hanging basket construction process, due to uneven load distribution, wind action, structural deformation, and other factors, the hanging basket may tilt. The traditional monitoring method is difficult to discover and adjust in time, which may cause the bridge alignment to deviate, affecting the aesthetics and structural stress performance of the bridge. In severe cases, it may cause the local stress of the bridge structure to be too large, shortening the service life of the bridge. SUMMARY

[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0027] Reference Figs. 1-3 An embodiment provided by the utility model: a bridge construction hanging basket safety protection system device, including walking track 1, the outer wall of walking track 1 one side is installed with displacement monitoring mechanism, it is used for real-time monitoring the displacement state journey change of hanging basket, the outer wall of walking track 1 one side is installed with lower chord 2, the outer wall of lower chord 2 one side is installed with front sliding support 3, one end of lower chord 2 is installed with front inclined rod 4, the other end of lower chord 2 is installed with rear inclined rod 5, and the top of front inclined rod 4 and rear inclined rod 5 is installed with upper chord 6, and the outer wall of upper chord 6 one side is installed with inclination monitoring mechanism, which is used for measuring the inclination change of hanging basket relative to horizontal plane, perpendicularity;

[0028] The displacement monitoring mechanism includes displacement sensor 7, and the displacement sensor 7 is installed on the outer wall of the lower chord 2. One end of the displacement sensor 7 is electrically connected with an alarm component, and the other end of the displacement sensor 7 is electrically connected with a power generation component.

[0029] The alarm component includes flashing light 8, and the inside of the flashing light 8 is installed with whistle 9. The flashing light 8 and the whistle 9 are electrically connected with the displacement sensor 7.

[0030] The power generation assembly includes a photovoltaic panel 10 installed on one side of the outer wall of the lower chord 2, and the output end of the photovoltaic panel 10 is electrically connected with the displacement sensor 7;

[0031] Specifically, the displacement monitoring mechanism continuously functions during the bridge construction process. The displacement sensor 7 adopts a high-precision laser ranging principle or a magnetic grating sensing principle, and can accurately measure the slight displacement change of the lower chord 2 relative to the walking track 1. When the hanging basket is moving, if the track is uneven, the traction system fails or is disturbed by external forces, the displacement sensor 7 can timely capture these changes. It calculates the displacement amount by emitting a laser beam or sensing a magnetic field change according to the change of the reflected signal or the sensed signal, and the measurement accuracy can reach millimeter level or even higher. Once the displacement amount exceeds the preset safety threshold, the displacement sensor 7 will immediately send an electrical signal to the alarm assembly and the power generation assembly. After receiving the signal, the alarm assembly starts flashing the strong light of the flashing light 8, and the flashing frequency can be adjusted according to the size of the displacement deviation, such as a slow flashing frequency for slight deviation and a faster flashing frequency for serious deviation, so that the construction personnel can intuitively judge the degree of displacement abnormality. At the same time, the whistle 9 emits a loud alarm sound, and the volume is enough to attract the attention of personnel in a noisy construction site, reminding the construction personnel to stop the movement of the hanging basket or other related operations, and to check and adjust the displacement of the hanging basket, such as checking whether the walking track 1 has obstacles and whether the traction equipment is running normally. The photovoltaic panel 10 in the power generation assembly generates electricity by using solar energy. During the daytime construction, the photovoltaic panel 10 absorbs solar energy and converts it into electrical energy to provide partial or full power support for the displacement sensor 7. The power of the photovoltaic panel 10 is selected according to the energy consumption of the displacement sensor 7 and the light conditions at the construction site, and generally adopts high-efficiency polycrystalline or monocrystalline photovoltaic panels 10, which have high photoelectric conversion efficiency and can ensure stable power supply for the displacement sensor 7 under different light intensities, reduce the dependence on external power supply, improve the autonomy and reliability of the system, and the role of the photovoltaic panel 10 is more prominent especially in some remote areas or unstable power supply conditions at the construction site.

[0032] The inclination monitoring mechanism includes an inclination sensor 11 installed on one side of the outer wall of the upper chord 6;

[0033] The inclination sensor 11 includes a horizontal inclination instrument and a vertical inclination instrument;

[0034] Specifically, the horizontal and vertical inclinometers monitor the inclination angles of the hanging basket in the horizontal and vertical directions, respectively. When the hanging basket carries construction loads, uneven load distribution, wind effects, or structural deformation of the hanging basket itself may cause the hanging basket to tilt. The horizontal inclinometer uses the principle of gravity sensing or gyroscope to accurately measure the change in the inclination angle of the hanging basket in the horizontal direction. For example, when the construction materials on one side are piled up too much or affected by lateral wind, the hanging basket will tilt in the horizontal direction. The horizontal inclinometer can detect this angle change in time and convert it into an electrical signal output. The vertical inclinometer focuses on monitoring the verticality change of the hanging basket in the vertical direction, which is crucial for ensuring the vertical stability of the hanging basket. During concrete pouring, if the support at the bottom of the hanging basket is uneven or the formwork is not installed vertically, the vertical inclinometer will detect the deviation of the verticality. Once the inclination angle detected by the inclinometer 11 exceeds the preset safety limit value, whether in the horizontal direction or the vertical direction, the corresponding alarm signal will be triggered, reminding the construction personnel to adjust the load distribution, support structure, or formwork installation of the hanging basket, to ensure the safety of the hanging basket and the construction quality.

[0035] The outer wall of the lower chord 2 is also provided with an anti-overturning device, which includes a wind-resistant pull rod 12. One end of the wind-resistant pull rod 12 is connected to the walking track 1, and the other end is installed inside the bridge body.

[0036] Specifically, in strong wind or other harsh environmental conditions, when the hanging basket is subjected to a large lateral wind force, the wind-resistant pull rod 12 can provide strong lateral tension to stably hold the hanging basket. The wind-resistant pull rod 12 is generally made of high-strength steel, and its tensile strength is sufficient to withstand the lateral force on the hanging basket in extreme conditions. Its one end is connected to the walking track 1 in a reliable manner, such as bolt connection or welding, to ensure the firmness of the connection; the other end is deeply embedded in the bridge body and fixed by a pre-embedded connecting piece, effectively transmitting the lateral force on the hanging basket to the main structure of the bridge, thereby preventing the hanging basket from overturning due to wind or other external forces.

[0037] Working principle: the working principle of the bridge construction hanging basket safety protection system device is as follows: the displacement sensor 7 in the displacement monitoring mechanism is installed on the outer wall of the lower chord 2, adopts laser ranging or magnetic grating sensing principle, emits laser beam or senses magnetic field change to accurately measure the displacement of the lower chord 2 relative to the walking track 1. Once the displacement exceeds the preset threshold, the electric signal is transmitted to the alarm component and the power generation component. The flashing light 8 of the alarm component adjusts the flashing frequency according to the displacement deviation, the whistle 9 emits loud alarm, reminds the construction personnel to check the hanging basket walking track 1, traction equipment and structure condition and corrects the deviation. The photovoltaic panel 10 of the power generation component utilizes solar energy, the internal semiconductor material generates electron-hole pairs to form current under light, supplies power for the displacement sensor 7, selects power according to its energy consumption and light, guarantees the autonomy and reliability of the system. The horizontal tilt angle instrument and the vertical tilt angle instrument of the inclination monitoring mechanism are installed on the outer wall of the upper chord 6, the horizontal tilt angle instrument borrows the principle of gravity sensing or gyroscope, such as the pendulum deviates from the balance position due to the horizontal inclination of the hanging basket, the detection circuit converts the angle change into an electric signal; the vertical tilt angle instrument monitors the vertical direction in the same way, and the two exceed the safety limit value to trigger the alarm, prompting the construction personnel to adjust the load distribution or support the formwork. The wind-resistant pull rod 12 of the anti-overturning device is connected to the walking track 1 at one end and is fixed in the interior of the bridge body at the other end, which is connected in a reliable way with high-strength steel. It stabilizes the hanging basket under normal circumstances, bears the tension in strong wind, accurately calculates its parameters according to various factors, transmits the tension to the bridge main body, prevents the hanging basket from overturning, and guarantees the construction safety and the stability of the bridge structure.
