[0012] To provide a more detailed understanding of the features and technical content of the embodiments of this disclosure, the implementation of the embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for illustrative purposes only and are not intended to limit the embodiments of this disclosure. In the following technical description, for ease of explanation, several details are used to provide a full understanding of the disclosed embodiments. However, one or more embodiments may still be implemented without these details. In other cases, well-known structures and devices may be simplified in their depiction to simplify the drawings.

[0013] The protective device used in this application for bridge construction includes a bridge 1, a bridge bottom support 2, an auxiliary construction platform 3, a suspended ladder 4, a cover side support 5, a cover top plate 6, a dust collection assembly 7, a construction traction assembly 8, an air conditioning assembly 9, and a detector 10.

[0014] The top plate 6 of the cover adopts an aluminum alloy telescopic structure, which consists of a main top plate and two auxiliary top plates on both sides. The auxiliary top plates are connected to the main top plate by sliding rails. The relative adjustment range of the two is 3-8 meters, which can adapt to bridges of different widths. In use, the width of the top plate 6 is adjusted so that the two ends of the top plate 6 overlap the edge of the bridge 1, and the auxiliary top plates protrude outside the edge of the bridge 1 by adjusting the top plate. Hydraulic telescopic cover side supports 5 are welded on both sides of the main top plate. The height support stroke is 0.5-4 meters, which can easily adapt to bridges of different heights. The bottom of the support is equipped with anti-slip rubber pads to increase the stability of the support.

[0015] The vacuuming component 7 is an industrial-grade negative pressure vacuum cleaner with a power of 2.2kW. The suction port extends to the construction area through a telescopic hose, and the vacuum cleaner's filter uses HEPA high-efficiency filter material. The air conditioning component 9 is a split-type air conditioner with a cooling capacity of 3.5kW. The air outlet is equipped with louvers to adjust the airflow direction. Both are remotely controlled via a wireless remote control model RF433.

[0016] The detector 10 integrates a PM2.5 sensor (model SDS011), a temperature sensor (DS18B20), and an AI behavior recognition camera with a resolution of 1080P. Its detection data is transmitted to the control console via a LoRa module. The detector 10 monitors the construction site environment in real time. When the dust concentration exceeds 0.5 mg / m³ or the temperature exceeds 35°C, the detector 10 automatically triggers an audible and visual alarm with a sound pressure level ≥85dB. At the same time, the detector 10 can also monitor the workers' work status. If violations, negligence, or slow construction progress occur, it can issue warnings to the construction personnel.

[0017] The construction traction component 8 includes a steel wire rope and a hook, and uses an electric hoist with a rated lifting capacity of 500 kg and a lifting speed of 8 m / min. The hook can be used to lift construction tools or materials, improving construction efficiency. The construction traction component 8 is designed to move along the length of the top plate 6 of the cover according to existing technology. The control method is a dual mode of wired handle + wireless remote control, so as to move with the hoisted construction materials.

[0018] The auxiliary construction platform 3 is a modular steel structure with dimensions of 2m×1.5m. It can be connected to the slot on the inner side of the cover side support 5 by bolts, making it easy to disassemble. The surface of the auxiliary construction platform 3 has anti-slip patterns, and the edge is equipped with a 1.2m high guardrail to prevent workers from falling. The suspended ladder 4 is a folding aluminum alloy ladder, which is fixed to the inner wall of the cover side support 5 by hinges. When unfolded, it is 3m high, and the step spacing is 30cm, so that workers can climb to reach the purpose of the auxiliary construction platform 3. The bridge bottom support 2 is located above the auxiliary construction platform (3) and is temporarily supported by the bridge bottom support 2. During the construction process, it supports the steel beams or concrete structures that have not yet been closed, preventing them from falling or becoming unstable, and increasing safety.

[0019] The usage steps are as follows: S1. Equipment deployment: Hoist the top plate 6 of the cover to the top of the bridge 1, adjust the extension length of the sub-top plate so that the overlap width at both ends is ≥50cm, start the hydraulic system of the cover side support 5, extend it to the ground and continue to lift it so that the distance between the top plate 6 of the cover and the bridge 1 reaches 3m. S2. Platform installation: Fix the auxiliary construction platform 3 to the inner slot of the cover side support 5 with bolts, unfold the suspension ladder 4 and lock it; S3. System debugging: Turn on detector 10, dust collection component 7 and air conditioning component 9, set PM2.5 alarm threshold to 0.5mg / m³ and temperature alarm threshold to 35℃, and test the lifting and moving functions of construction traction component 8; S4. Construction Operation: Construction personnel enter the side construction area through the suspended ladder 4, carry out bridge bottom work using the auxiliary construction platform 3, hoist materials using the construction traction component 8, and monitor the environment and personnel status in real time using the detector 10. S5. Equipment Removal: After construction is completed, dismantle the auxiliary construction platform 3, retract the suspended ladder 4, retract the side support of the cover shell 5 so that the top plate of the cover shell 6 falls to the surface of the bridge 1, adjust the sub-top plate to reset, and hoist the transfer device.

[0020] In this embodiment, the protective device for bridge construction can adapt to bridges of different widths by adjusting the width of the top plate of the cover and minimize the impact of the external environment on construction. The detector installed on the top plate of the cover can detect the temperature and harmful gases generated during construction. The dust collection component and air conditioning can effectively improve the construction environment and increase the comfort of construction. The construction traction component can lift construction tools or materials, effectively improving construction efficiency. The side support of the cover can be equipped with a suspension ladder to enable simultaneous construction at different locations on the bridge.

[0021] This protective device for bridge construction effectively isolates the bridge from the external environment, reducing noise and dust, minimizing interference with the external environment, and minimizing safety hazards. It ensures construction safety and allows for simultaneous construction on the bridge top, bottom, and sides without the need for external tools. Its versatile functionality and high flexibility meet diverse usage needs, enabling efficient and rapid construction.
