Abstract

The invention discloses an engaged round pipe shock-resistance multistage energy absorbing device. The device comprises an upper-layer panel, a middle engaged round pipe combined sandwich layer and a lower-layer panel. The middle engaged round pipe combined sandwich layer is an embedded composite structure formed by longitudinally placing multiple round pipes with different diameters in parallel. The upper-layer panel and the lower-layer panel are trapezoidal corrugated sandwich plates, wherein trapezoidal corrugated layers are placed in the transverse directions of structures to improve the transverse energy absorbing characteristics of the structures. A layered multistage buffer energy absorbing device formed through the embedded round pipe section design can reduce initial peak value loads borne by the structures through the design of round pipes with different sizes, improves the volume ratio energy absorption of the structures, saves the space to the greatest extent, and meanwhile, can select corresponding energy absorbing environments according to impact loads with different magnitudes.

Description

technical field [0001] The present invention relates to the technical field of energy absorbing devices. Specifically, the present invention is a nested circular tube combined multi-stage energy absorbing device that is applied to elevator floors under emergency conditions and has impact resistance and energy buffering. Background technique [0002] With the development of economy and the acceleration of urbanization, the number of high-rise buildings in major cities is increasing, which also leads to a sharp increase in the number of elevators. However, in recent years, frequent elevator accidents have seriously affected people's life and property safety. Therefore, how to reduce The hazards caused by elevator falling accidents have become a topic of great concern to people. Commonly used elevator anti-falling safety devices are mainly divided into three types: 1. Anti-falling safety device. When the falling speed reaches 1.6 times the normal operating speed, the safety dev...
