AI Technical Summary
Existing shock absorption devices are inconvenient to replace vulnerable components and lack protection. During explosions, they may cause debris to fly, posing a safety hazard.
A buffer-type blast shock absorber was designed, featuring quick replacement of vulnerable components, rapid assembly of splicing components, and protective components. It includes a support frame, damping components, buffer components, and protective components. Quick replacement and assembly are achieved through elastic elements and movable pull rings to prevent debris from flying.
It improves the maintenance efficiency of the device, adapts to use in blast holes of different depths, prevents debris from injuring people and damaging property, and enhances safety and work efficiency.
