Benefits of technology

This patented technology describes a new type of material called Toughness Composite Buffer used for building materials such as roofs or walls. These buffers are designed to absorb high levels of force while still allowing it to slide smoothly on their surfaces. They also have a layer made from rubber instead of metal to prevent braking caused by excess pressure applied through them. Overall, these technical features make sure they work well even if there've been any sudden changes in temperature conditions.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the efficiency or reliability of active flexibility safety structures (AFS) against various types of environmental hazards like slopes. These threats require effective ways to reduce their potential harm caused during an event's occurrence while still maintaining sufficient energy absorption before they become too severe. Current methods involve adding sacrificial elements at certain points along with energy disseleration devices to absorb excess kinetic energy from collisions without causing permanent damage.

Embodiment 1

[0097] This embodiment intends to design a flexible composite buffer applied to the small energy level flexible protection system. According to the recommendation of the specification, the spring steel material grade is 60Si2Mn, and the steel pipe material is Q235 steel. The flexible composite buffer described in this embodiment adopts a buffer spring, and each plate and each connecting member is adjusted accordingly according to the design, such as figure 1 shown.

[0098] according to figure 1 Computational design is performed as shown in the design flow:

[0099] According to the existing experiments and numerical simulations, determine the tension F of the support rope in normal use sel =30kN

[0100] According to the demand, the maximum deformation of the preset spring is s=250mm

[0101]Preliminary design and determine the number of springs m = 1

[0102] To calculate the spring bar diameter d, use the equation Carry out the calculation, refer to the specification an

Abstract

The invention discloses a tough composite buffer for a slope flexible protection system. The tough composite buffer comprises a support steel pipe, a sliding plate, a buffering spring and a first steel inhaul cable; the two ends of the support steel pipe are fixed on a spring base plate and a pull anchor plate correspondingly; a sliding plate hole is formed in the sliding plate, and the supporting steel pipe penetrates through the sliding plate hole so that the sliding plate can be arranged on the supporting steel pipe in a sliding and sleeving mode; the buffering spring is arranged on the supporting steel pipe in a sleeving mode, and the two ends of the buffering spring are connected to the spring base plate and the sliding plate correspondingly; one end of the first steel inhaul cable penetrates through the sliding plate and is anchored on the sliding plate through a metal rope anchor, and the other end of the first steel inhaul cable is connected to a first supporting rope; when the impact energy of the system is within a normal working energy level range, the buffering spring works independently, generates elastic deformation and recovers along with cleaning of falling rocks; and when the impact energy exceeds the normal working energy level, a starting supporting steel column is bent to achieve composite energy consumption.
