The invention discloses an energy dissipation component for a passive protection net. The energy dissipation component can be used repeatedly, and energy dissipation ability is stable and adjustable. The energy dissipation component comprises a base steel sling, a steel sling and a friction steel cylinder, wherein a near-end penetration hole and a far-end penetration hole which penetrate through the wall of the friction steel cylinder are formed in the near end and far end of the friction steel cylinder respectively, and the steel sling protrudes out of the friction steel cylinder through the far-end penetration hole, then is wound around the outer wall of the friction steel cylinder for several circles, protrudes into the friction steel cylinder through the near-end penetration hole and finally protrudes out through the near end port of the friction steel cylinder; a sling clip is fixedly connected to the near end of the steel sling, and the base steel sling is connected with the near end of the friction steel cylinder through a connecting component.
Description
technical field [0001] The invention relates to a protective net, in particular to an energy dissipation component applied to a passive protective net. Background technique [0002] The slope passive protection net is a fence-type flexible system mainly composed of steel wire ropes. Seat and support rope), decompression ring and steel column four main parts. The system is generally set at a certain position on the slope, and is used to intercept falling rocks on the slope to prevent it from damaging the protected object. Therefore, it sometimes becomes a stone blocking net. [0003] As we all know, during the implementation of the protective net, it is usually necessary to set up energy dissipation rings. The energy dissipation ring, also known as the decompression ring, mainly plays the role of buffering and energy dissipation, and is one of the main components of the passive slope protection net. It is composed of tightly arranged spiral ring-shaped steel pipes and fix...
