Description
Technical field
The present invention relates to shield/TBM design and manufacturing technology fields, and in particular to a kind of Novel cutter for preventing hobboing cutter eccentric wear
Seat.
Background technique
Shield/TBM is increasingly used in constructing tunnel in recent years, shield/TBM due to faster construction speed,
The boring mode of safety becomes the preferred equipment of constructing tunnel.It is affected whether wherein shield/TBM cutterhead hobboing cutter design is reasonable
The speed of construction work, but since shield/TBM environment being applicable in becomes increasingly complex, the becoming increasingly complex of abrasion of hobboing cutter,
The key factor that hob abrasion becomes control drivage efficiency, influences construction cost.
Hob abrasion consuming cost already takes up the 20% ~ 35% of construction equipment cost in ground consisting of hard rock driving, wherein rolling
The heel and toe wear of knife also takes up 30% of hob abrasion or more, and the overwhelming majority is hobboing cutter eccentric wear in heel and toe wear.According to research
It was found that hob abrasion mainly rolls abrasion, side wear and tangential abrasion, wherein side wear is the master for causing hobboing cutter eccentric wear
Want factor.
The principal element for causing hob abrasion is because traditional hobboing cutter installation is rigid installation, and hobboing cutter and cutterhead become
One rigidity is whole.In broken rock, by great oscillatory load, and in broken rock, hobboing cutter encounters hard-soft heterogeneous ground or orphan to hobboing cutter
Hobboing cutter posture cannot be effectively adjusted when stone, cause hobboing cutter eccentric wear and tipping.
Summary of the invention
In view of this, preventing the novel of hobboing cutter eccentric wear in view of the deficiencies of the prior art, it is an object of the present invention to provide a kind of
Tool apron avoids hobboing cutter eccentric wear and abrasion by adjusting the axis angle of hobboing cutter and hobboing cutter, solves that traditional hobboing cutter is easy to wear, Yi Fa
The problem of raw eccentric wear and tipping.
In order to achieve the above objectives, the invention adopts the following technical scheme:
A kind of Novel cutter holder preventing hobboing cutter eccentric wear, the pedestal including being symmetrically mounted on hobboing cutter two sides, is equipped in the pedestal
Opening up U-typed mounting groove is led along perpendicular on the hobboing cutter axis direction equipped with sliding in the bottom of the mounting groove
Slot is equipped with the fixed block slided with it on the sliding guide groove, is equipped on the fixed block for connecting hobboing cutter knife
The oscillating bearing of axis is respectively equipped with elastic element among the mounting groove and fixed block.
Feature in view of the above technology, hardness of the oscillating bearing in hobboing cutter operation according to rock can generate turning for low-angle
It is dynamic, so that hobboing cutter be made to have a certain range of rotation, avoid the feelings that abrasion or tipping occur when encountering impact more energetically for hobboing cutter
Condition；Elastic element is existed due to that hobboing cutter can be made to generate certain displacement in a forward direction with certain elasticity for hobboing cutter
Adjustment appropriate can be made when discontinuity, to change the stress of hobboing cutter, avoid hobboing cutter that eccentric wear occurs；Work as hobboing cutter
When being blocked in broken formation tunneling process by stone, moved by fixed block in sliding guide groove to change hobboing cutter spacing dimension,
To effectively avoid the case where hobboing cutter is by card.
Preferably, the pedestal is assembled by the first attachment base and the second attachment base, and centre is fixedly connected by fixing piece.
Preferably, the fixed block is made of the first fixed block and the second fixed block, the first fixed block and the second fixed block
It is installed on after assembly in the mounting groove.
Pedestal and fixed block are made of separate structure, are mounted and dismounted in use more convenient.
Preferably, the sliding guide groove includes the interior trapped orbit connecting with the fixed block, is arranged in the mounting groove
The outer trapped orbit of bottom, and the steel ball being mounted between interior trapped orbit and outer trapped orbit；The interior trapped orbit can
Sliding is installed in outer trapped orbit, and is slided along outer trapped orbit.The structure and fixed block it is easier for installation.
Preferably, the sliding guide groove is in " work " type structure.Endurance is big, increases the stability of hobboing cutter, prevents on hobboing cutter
Lower offset.
Preferably, the groove for clamping oscillating bearing is equipped on the mounting blocks.
Preferably, the oscillating bearing is made of inner ring and outer ring, the interior table of the outer surface of the inner ring and the outer ring
Face is spherical surface.
Preferably, the rotational angle of the oscillating bearing is 2-5 °.It is unstable that ambassador's hobboing cutter is crossed to prevent rotational angle.
The beneficial effects of the present invention are:
In the present invention oscillating bearing can Small-angle Rotation both played the role of fixed hobboing cutter cutter shaft, again may be used in hobboing cutter unbalance stress
To adjust hobboing cutter position by Small-angle Rotation, hobboing cutter mode eccentric wear is prevented.When hobboing cutter stress is larger with fixed block along cunning
Dynamic guide groove is mobile, changes hobboing cutter stress, when preventing hob abrasion or collapse tooth, while being blocked between hobboing cutter and tool apron by stone
Discharge stone can be moved along sliding guide groove by fixed block, prevent hobboing cutter eccentric wear and blocked；Sliding guide groove is in " work " type structure
It effectively avoids hobboing cutter from shifting up and down, increases hobboing cutter stability.Elastic element plays the role of adjusting hobboing cutter position, in hobboing cutter
Stress can guarantee that hobboing cutter can be tunneled normally when smaller, and when stress is larger, elastic element deforms, and adjust hobboing cutter position
It sets, guarantees hobboing cutter uniform stressed.
Present invention can ensure that hobboing cutter adjusts hobboing cutter position and angle in improper stress, hobboing cutter eccentric wear is avoided；Multiple
Under miscellaneous formation condition, when hobboing cutter is blocked by stone, prevent stone from falling by changing hobboing cutter position；The present invention effectively prevent hobboing cutter
The case where eccentric wear, tipping and abrasion, effectively extend the service life of hobboing cutter, reduces hobboing cutter replacement and maintenance frequency, improve construction
Efficiency reduces cost.
