Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a novel protective device for construction engineering. Background Art

[0002] New construction projects are based on traditional construction engineering technologies and use emerging technologies and new materials to achieve innovation and improvement in construction, design, management, and maintenance. During construction, protective devices are used to ensure the safety of personnel and equipment and prevent accidents.

[0003] According to a protective device for construction projects disclosed in Chinese patent CN210316804U, the anti-collision effect of the device is improved by setting an anti-collision plate and a buffer spring, avoiding or reducing collisions between vehicles and people and the device, so that the device provides a certain buffering effect and reduces the strain on the impacting object and the impacted object.

[0004] The aforementioned device uses a buffer spring to mitigate the impact force of the impact plate after it is hit. However, the buffer spring is prone to deformation and corrosion over time. Furthermore, after prolonged use, it fatigues, causing deformation and loss of its original elastic function, thereby reducing its buffering performance. Therefore, we provide a new protective device for construction projects. Utility Model Content

[0030] And an operating assembly 4 fixedly connected to the inside and outside of the frame 2; the operating assembly 4 includes an anti-collision portion 41 fixedly connected to the front and rear sides of the frame 2, and the anti-collision portion 41 is connected to a protective portion 42.

[0031] The anti-collision part 41 includes a square frame 411 fixedly connected between the railings 3, the inner surface of the square frame 411 is fixedly connected with a guide rod 412, the outer wall of the guide rod 412 is slidably connected with a guide block 413, the outer wall of the guide frame 413 is fixedly connected with a moving rod 415, the front side of the moving rod 415 is hinged with an adjusting rod 416, the end of the adjusting rod 416 away from the moving rod 415 is hinged with an anti-collision plate 417, the rear side of the guide block 413 is fixedly connected with a buffer spring 414, and the end of the buffer spring 414 away from the guide block 413 is fixedly connected to the inner surface of the square frame 411.

[0032] In this embodiment, the anti-collision plate 417 is arranged in front of the frame 2. The material of the anti-collision plate 417 is set to a carbon fiber plate. The anti-collision plate 417 is used to play an anti-collision role for the entire guardrail. At the same time, the carbon fiber material improves the strength of the anti-collision plate 417 and can effectively absorb and disperse impact force.

[0033] Example 2: Based on Example 1, the new type of protective device for construction engineering provided by the present invention is as follows: Figures 1 to 5 As shown: the protective part 42 includes a double-sided gear rod 421 fixedly connected to the back of the moving rod 415, the side of the double-sided gear rod 421 is engaged with a transmission gear 422, the inner wall of the transmission gear 422 is fixedly connected with a rotating shaft 423, the upper and lower ends of the rotating shaft 423 respectively pass through the upper and lower sides of two bellows 424, and are fixedly connected with fan blades 426, the two bellows 424 are respectively fixedly connected to the rear side of the frame 2 through a fixing frame 425, a ventilation pipe 427 is provided between the two bellows 424, the side of the ventilation pipe 427 is provided with an air guide pipe 428, and the front end of the air guide pipe 428 is provided with a protective airbag 429.

[0034] In this embodiment, the upper and lower ends of the rotating shaft 423 and the two bellows 424 are configured to be movable and penetrated, and are rotatably connected to the inner wall of the bellows 424 through bearings, so that the rotating shaft 423 can drive the fan blades 426 to rotate and generate wind.

[0035] Furthermore, the number of the fan blades 426 is set to four, and every two fan blades 426 are set as a group, and are positioned inside the wind box 424. The wind generated by the rotation of the fan blades 426 is concentrated by the wind box 424.
