On cutter head structure.When work, hobboing cutter with cutterhead along circular trace when being rolled in excavation face, blade squeeze rock, make rock
Conquassation is crushed to the purpose up to rock cutting.
Current hobboing cutter, for example, self-positioning disc-type hob device disclosed in Chinese patent CN102635366A and
Full face rock tunnel boring machine hobboing cutter locking device disclosed in CN106837366A has only locked cutter shaft center cutter shaft seat below
The body structure surface of the cutter shaft seat of cutter shaft center line or more is not locked on inclined-plane；In order to facilitate replacement cutter, cutter shaft seat and girff exist
There is certain gap in the hobboing cutter direction of motion；It designs and mainly considers the reaction force that hobboing cutter squeezes rock generation, to hobboing cutter
Suffered tangential friction force and impact force and thus generate harm consider it is insufficient；Hobboing cutter during long-time broken rock, with
The stress surface and other indirect stress surfaces that cutter shaft seat is in contact, can not be effective against tangent direction friction resistance and impact force, cause compared with
There are weak vibrations in turn in the contact surface abrasion and deformation of softwood matter, cutter shaft seat, and connection bolt gradually loosens, as vibration aggravates
Hobboing cutter is ultimately caused to fall.
And shield machine disk cutter installation locking system disclosed in Chinese patent CN108119155A, although to cutter shaft center
Cutter shaft seat more than line is locked, but is fixed below cutter shaft center line using tension block, and vertical by bolt
Connection, in this way under the long-term vibration of hobboing cutter, the screw thread of bolt is easy to polish loosening, causes cutterhead to be easy to fall off, and bolt
It needs to be torqued into cutter shaft seat, install complicated laborious.
