Description
Technical field
The utility model is related to the rock tunnel(ling) machine in constructing tunnel, particularly relates to a kind of propelling cylinder cylinder barrel end and circumferentially adjusts
Engagement positions.
Background technology
TBM is the abbreviation of tunneling boring hard rock tunnel development machine, is the special equipment of tunnel excavation, in mountain tunnel and city
Played an important role in the construction of subway.According to TBM operation principle and structure type, TBM includes shield formula TBM and opened wide
Formula TBM.
Shield formula TBM is in work progress, it is necessary to be cutterhead fractured rock using the propelling cylinder being fixed on inside shield body
Thrust is provided, cutterhead can produce a reaction force to shield body in fractured rock, in turn result in the rolling of shield body.The rolling of shield body
The posture of change of team influence TBM complete machine drivings, stress and normal driving to TBM exert an adverse impact.
When rolling occurs for shield body, it is necessary to be entered by adjusting rolling of the position of propelling cylinder in a circumferential direction to shield body
Row is corrected, to ensure that shield formula TBM can be tunneled with correct posture.In addition, by adjusting propelling cylinder in circumference side
Upward position can also prevent the generation of shield body rolling to a certain extent.
Utility model content
The utility model proposes a kind of circumferential adjusting apparatus in propelling cylinder cylinder barrel end, solve and adjust TBM in the prior art
The problem of driving attitude.The device can adjust shield formula tunneling boring hard rock mole（TBM）Propelling cylinder is in a circumferential direction
Position, and then adjust shield formula TBM shield bodies posture.
What the technical solution of the utility model was realized in：A kind of circumferential adjusting apparatus in propelling cylinder cylinder barrel end, including
Some adjustment structures, adjustment mechanism includes propelling cylinder, and the cylinder barrel bottom of propelling cylinder is flexibly connected with adjustment base, adjusts bottom
Seat is slidably matched with the track in adjustment block, and adjustment block is fixed in shield body, and adjustment oil cylinder one end is fixedly connected with adjustment block, separately
One end is fixedly connected with adjustment base；Boots plate is movably connected at propelling cylinder right hand piston bar, and it is right that fixed block is fixed on shield body
End, propelling cylinder is fixedly connected close to the cylinder barrel of tailpiece of the piston rod with fixed block.
At the cylinder barrel bottom of described propelling cylinder and adjustment base bulb hinged, boots plate and propelling cylinder right hand piston bar
Bulb hinged.
Described adjustment mechanism is located in shield body, and is circumferentially uniformly distributed along shield body.
The utility model can be by adjusting rotation of the control propelling cylinder in circumferencial direction, when propelling cylinder is being promoted
When, one component in opposite direction with rolling of shield body can be given, the purpose of adjustment shield body posture is reached, it is ensured that shield formula TBM can
Tunneled with correct posture.
