Description
Technical field
The invention belongs to various weak soil earth jolt ramming engineering fields, more particularly to various vibrating impacter shock dampers and its system
Standby technique.
Background technology
The vibrating impacter of stake is made in existing jolt ramming, and its damper is serration packaging type rubber absorbers, and damper bottom is method
Blue mode connects for screw form.The damper of the form in use, has the following disadvantages：
1st, serration and rubber elastomer contact area are small, and in the case of high pulling torque, easily elastomer is torn along warp-wise, resist
Turn round ability；
2nd, when vibrating impacter is made in metalling, because recoil strength is very big, causes the longitudinally cutting rubber elastomer of serration again, cause
Elastomer is squeezed broken vertically, anti-axial thrust and pulling force ability, thus reduces damping effect；
3rd, because damper bottom is fastenedly connected for flange screw, under the periodically high-frequency vibrations of vibrating impacter, spiral shell is fastened
Nail easily loosens；The result that trip bolt loosens, is exactly that screw slowly comes off, and flange departs from damper, can cause to shake when serious
Rush device and come off and fall into stake holes；Also, during coming off, energization cable breakage can be caused, cause unexpected electric shock
Accident.
In summary, in use, not only short life, replacement cost is high for existing damper, and exists very big
Potential safety hazard.
