Foundation pit safety protection device for municipal road
The invention discloses a foundation pit safety protection device for municipal roads, and relates to the technical field of construction protection, the foundation pit safety protection device comprises two stand columns and a cross beam, the two ends of the cross beam are connected with the tops of the two stand columns respectively, the bottoms of the two stand columns are jointly connected with a bottom plate, and a plurality of parallel rotating shafts are rotatably connected between the cross beam and the bottom plate; when wind power is large, by means of the narrow pipe effect and the Bernoulli principle, the movable plates in the grooves are pressed to slide to extrude the stop blocks at the groove openings, the piston plates are triggered to slide upwards, and through meshing transmission of the spur racks and the gears and meshing transmission of the first bevel gears and the second bevel gears, the movable plates are driven to rotate, so that the wind power is increased, and the working efficiency is improved. All the rotating shafts rotate by 90 degrees and drive the protection plates to rotate together, so that the wind area of the whole device is reduced, the wind resistance is reduced, the device is prevented from being blown down by strong wind, and the stability of the device in severe weather is improved.
本发明公开了一种市政道路用基坑安全防护装置，涉及施工防护技术领域，包括两根立柱和横梁，所述横梁的两端分别与两根立柱的顶部相连接，两根所述立柱的底部共同连接有底板，所述横梁与底板之间转动连接有多根相互平行的转轴，每根所述转轴上安装有防护板，本发明在风力较大时，利用狭管效应和伯努利原理，使凹槽内的活动板受压强滑动对凹槽口处的挡块进行挤压，触发活塞板上滑，通过直齿条与齿轮啮合以及第一锥齿轮和第二锥齿轮的啮合传动，使所有的转轴将发生90°转动，并将带动防护板一起转动，减少整个装置的受风面积，降低风阻，防止装置被大风刮倒，提高装置在恶劣天气下的稳定性。
