The invention discloses a safe evacuation early warning device for railway construction. The device comprises a base, and an inner cavity with a leftward opening is formed in the base. The lower wallof the inner cavity is communicated with a sliding cavity with a downward opening; the lower wall of the sliding cavity is communicated with a cavity; a bottom plate is fixedly arranged on the lower wall of the cavity; supporting rods are fixedly connected to the left and right sides of the lower end of the bottom plate; the lower end of the supporting rod is fixedly connected with a supporting rod wheel; a transmission belt wheel shaft is rotationally connected into the supporting rod wheel; the front and rear sides of the transmission belt wheel shaft are fixedly connected with transmissionbelt wheels respectively. The whole device can be automatically clamped on the surface of a rail through gear engagement and spring compression, and workers for carrying is not needed; and meanwhile,whether the train enters a set range or not is automatically detected according to the principle of a circuit, early warning is conducted on workers in construction in time, meanwhile, the train is automatically evacuated to a safe position, a large number of manpower and material resources are saved, the working efficiency is improved, and the life safety of the workers is fully guaranteed.
本发明公开的一种铁路施工可安全撤离预警装置,包括底座,所述底座内设有开口向左的内腔,所述内腔下壁连通有开口向下的滑动腔,所述滑动腔下壁连通有空腔,所述空腔下壁固设有底板,所述底板下端左右侧分别固连有支撑杆,所述支撑杆下端固连有支撑杆轮,所述支撑杆轮内转动连接有传动带轮轴,所述传动带轮轴上前后侧分别固连有传动带轮,本发明可通过齿轮啮合与弹簧压缩使装置整体自动卡在铁轨表面,无需工作人员进行搬运,同时利用电路的原理自行检测火车是否进入设定范围,并及时对正在施工的工作人员进行预警,同时自动撤离运动至安全位置,节省大量的人力物力,提高工作效率,充分保证了工作人员的生命安全。
