The utility model relates to a multi-level honeycomb energy absorbing anti climbing device with an external guide, which comprises an anti climbing tooth and a first-class honeycomb under the anti climbing tooth. The two sides of the anti climbing tooth are provided with a first-class honeycomb external guide, the first-class honeycomb external guide is connected with the second-class honeycomb external guide by sliding, two smooth rods are penetrated at two ends of the anti climbing tooth bottom plate, one end of the smooth rod is welded on the anti climbing tooth bottom plate, and the other end is installed through the honeycomb The first level honeycomb and the second level honeycomb are respectively placed in front and back of the honeycomb installation slot. The first level honeycomb is sandwiched between the anti climbing tooth and the honeycomb installation slot, and is locked by the light rod with the nut to ensure the position and fixed. The lower part of the second level honeycomb external guide is connected with the guide base flange through the second level honeycomb safety pin. When the collision force does not reach a certain value, only the first level honeycomb works independently, thus Protect the secondary honeycomb. When the collision force reaches a certain value, the safety pin of the secondary honeycomb will be cut off, and the secondary honeycomb will be opened for energy absorption. Second level cell and first level cell are avoided to work together, waste is avoided and cost is saved.
【技术实现步骤摘要】
一种带有外导向的多级蜂窝吸能防爬器
本专利技术属于城市轨道交通被动安全防护领域,尤其是涉及一种多级蜂窝吸能防爬器。
技术介绍
被动安全防护装置广泛应用于汽车、轨道交通车辆、超高层建筑电梯井等行业,其中目前较为常用的是蜂窝式吸能装置,其工作原理是通过蜂窝结构塑性变形吸能。但因突发事故的严重程度不同,承受冲击载荷时,吸能装置需要通过导向管来确保变形方向,从而保证蜂窝吸能。而现有的吸能装置通常采用在加工完蜂窝后,在蜂窝内部添加导向管,在加工蜂窝时会增加加工工序,增加加工难度,在安装时会增加配合误差,影响吸能效果。在撞击后更换蜂窝较复杂。综上所述,原有内置导向管制造困难,成本较高,经济性差。
技术实现思路
本专利技术的目的是提供一种带有外导向的多级蜂窝缓冲器装置,在满足吸能要求的前提下,通过导向管放置于蜂窝外侧,蜂窝吸能时不会产生偏斜、弯曲。而且可以通过蜂窝安全销和导向管相配合,实现一级蜂窝和二级蜂窝针对不同碰撞力值时发挥相应的作用,大大提高了防爬吸能装置的经济性和可维护性。为实现上述目的,本专利技术提供一种带有外导向的多级蜂窝吸能防爬器,包括防爬齿、防爬齿下面的一级蜂窝,其特征在于:防爬齿两侧面有一级蜂窝外导向,一级蜂窝外导向与二级蜂窝外导向滑动配合连接,防爬齿底板处两端穿入两根光杆,光杆一端焊接在防爬齿底板上,另一端穿过蜂窝安装槽固定,蜂窝安装槽前后分别放入一级蜂窝与二级蜂窝,其中一级蜂窝夹在防爬齿与蜂窝安装槽中间,并由光杆以螺母锁紧保证位置并固定,二级蜂窝外导向下面通过二级蜂窝安全销与导向底 ...
