The invention relates to the technical field of subway security and protection, and discloses a subway safety protection anti-climbing device, which comprises a guide cylinder, a tooth-shaped plate is fixedly connected to one side of the guide cylinder, a mounting plate is fixedly connected to the other side of the guide cylinder, and an induction groove is formed in the side wall of the tooth-shaped plate; a first rigid energy absorption area is formed in the left side of the interior of the guide cylinder, and a buffer area is formed in the middle of the interior of the guide cylinder. The motor drives the threaded lead screw to rotate, so that the triggering base rotates and moves leftwards, and the honeycomb energy absorption units are stretched and expanded; and then, the stress rod extends into the induction groove and is tightly embedded in the induction groove, so that the stress rod plugs the groove hole in the induction groove to share and bear the concentrated stress of the induction groove. When the longitudinal pressure static strength is larger than the bearing capacity of the stress rod, plastic deformation occurs, so that the triggering base transmits energy to the honeycomb energy absorption unit for energy absorption, and the problem that the energy absorption structure is plastically deformed in advance due to the fact that the concentrated stress of the induction groove is too large under the longitudinal pressure static strength is solved.

    本发明涉及地铁安防技术领域,且公开了一种地铁安全防护防爬器,包括导向筒,所述导向筒的一侧固定连接有齿形板,所述导向筒的另一侧固定连接有安装板,所述齿形板的侧壁开设有诱导槽,所述导向筒内部的左侧开设有第一刚性吸能区,所述导向筒内部的中间开设有缓冲区。本发明通过电机驱动螺纹丝杆旋转使得触发底座向左旋转移动,使得蜂窝吸能单元被拉伸扩展开来,应力棒伸入诱导槽中紧紧嵌在其中,实现了应力棒塞住诱导槽中槽孔分担承受诱导槽的集中应力,当纵向压力静强度大于应力棒的承受能力就会发生塑性变形使得触发底座传递给蜂窝吸能单元吸能,解决了诱导槽在纵向压力静强度下集中应力过大导致吸能结构提前塑性变形的问题。
