On the basis of above technical scheme, it is preferred that described prism is quadrangular or six prisms.Further
Preferably, described quadrangular or six prism circumscribed circle diameters are 0.5～0.8:1 with threaded rod diameter proportion.More enter
One step is preferred, described threaded rod a length of 5～10cm, a diameter of 0.8～1.2cm.It is further preferred,
The a length of 7cm of described threaded rod, a diameter of 1cm, described quadrangular or six prism circumscribed circle diameters are 0.8cm.
On the basis of above technical scheme, it is preferred that described revolving support surface configuration has the first screw thread to lead to
Hole, it is interior and the most threaded that bolt is arranged at the first tapped through hole, described threaded rod end and the first screw thread
Through hole end face is concordant or is positioned at the first tapped through hole.
On the basis of above technical scheme, it is preferred that described lower vehicle frame surface configuration has the second tapped through hole,
It is interior and the most threaded that bolt is arranged at the second tapped through hole, described threaded rod end and the second tapped through hole
End face is concordant or is positioned at the second tapped through hole.
Excavator revolving support attachment means the having the beneficial effect that relative to prior art of the present invention: logical
Cross the bolt of the prism that depression or protrusion are set, can be taken out by spanner segmentation when bolt fracture, it is not necessary to
Employ large-scale auxiliary equipment or dismantle excavator on a large scale, convenient dismounting and maintenance, more safe efficient.
