Description
Technical field
The present invention relates to tunnel construction machinery field more particularly to a kind of TBM cutterheads that modularization reducing digs.
Background technique
The TBM such as high-ground stress, country rock large deformation, deep tunnel TBM card machine mechanism are frequently encountered during constructing tunnel
Tunnel excavation problem.In high ground stress soft rock stress Tunnel Design and construction, generallys use deformation allowance, supporting means, excavates
The technical measures such as engineering method can effectively control the generation of large deformation, guarantee engineering safety.Tunnel deformation allowance is sufficiently to send out
Country rock self-supporting is waved, preliminary bracing and country rock is allowed to have certain deformation, and design excavation line is made into suitably widened reserve
Amount, referred to as tunnel deformation allowance.For the technical measures of deformation allowance in constructing tunnel, there are no corresponding TBM at present
Engineering machinery.
Summary of the invention
For the problems of in the prior art, a kind of TBM knife that modularization reducing digs provided by the present invention
Disk makes it possible to when encountering high ground stress soft rock stress tunnel, and a kind of modularization reducing that can be provided through the invention digs
TBM cutterhead realize expanding excavation so that excavation line makees appropriate expand to deformation allowance.
Technical scheme is as follows:
A kind of TBM cutterhead that modularization reducing digs includes the center cutter disk module for being equipped with center steering body, and
The periphery cutterhead module being arranged around center cutter disk module, the periphery cutterhead module are arranged to around center cutter disk module
One circular beater plate, the center cutter disk module is connected by pipe bending cylinder with periphery cutterhead module, so as to pass through pushing tow
Oil cylinder pushing tow periphery cutterhead module makes the diameter of entire circular beater plate become larger.
Preferably, the excavation face of the center cutter disk module is quadrilateral structure, and corresponding periphery cutterhead module shares four
A, the excavation face of periphery cutterhead module is sector structure, is located on four sides of center cutter disk module, be combined into one it is whole
Round cutterhead.
Pass through two pipe bending cylinder connections, the bottom of pipe bending cylinder between the center cutter disk module and periphery cutterhead module
Seat is fixedly mounted on center cutter disk module, and the piston rod head of pipe bending cylinder is fixedly mounted in the cutterhead module of periphery, and pushing tow
Oil cylinder is located at full circle cutterhead close to the one side of Tu Cang.
Further, the hobboing cutter on the full circle cutterhead is arranged using the multiple tool mode of a rail, i.e., in same operation
Multiple hobboing cutters are arranged on track, so that track operation when there are also hobboing cutters according to non-variable diameter after variable diameter.
Beneficial effects of the present invention: center cutter disk module is arranged by cutterhead modularization in the present invention, periphery cutterhead module
It is installed around center cutter disk module, to be assembled into the cutterhead of a full circle, and center cutter disk module and periphery cutterhead
It is connected between module by pipe bending cylinder, so as to realize that variable diameter is excavated by pipe bending cylinder promotion periphery cutterhead module,
So that excavation line make it is appropriate expand to deformation allowance, effective solution is in constructing tunnel, the big change of high ground stress soft rock stress
Shape digs problem.

Description of symbols: 1. center cutter disk modules；2. periphery cutterhead module；3. pipe bending cylinder；4. hobboing cutter.
Specific embodiment
The present invention will be further described below in conjunction with the drawings of the specification.
It elaborates referring to the optimum embodiment that attached drawing 1 is invented to 3 Duis of attached drawing, what a kind of modularization reducing digged
TBM cutterhead includes the quadrilateral structure center cutter disk module 1 for being equipped with center steering body, and around center cutter disk module 1 four
While the periphery cutterhead module 2 for the sector structure being arranged, the periphery cutterhead module 2 is located at center cutterhead mould for totally four
On four sides of block 1, so that it is arranged to a circular beater plate, it is logical between the center cutter disk module 1 and periphery cutterhead module 2
It crosses two pipe bending cylinders 3 to connect, the pedestal of pipe bending cylinder 3 is fixedly mounted on center cutter disk module 1, the piston of pipe bending cylinder 3
Head is fixedly mounted in periphery cutterhead module 2, and pipe bending cylinder 3 is located at full circle cutterhead close to the one side of Tu Cang.The full circle
Hobboing cutter 4 on cutterhead is arranged using the multiple tool mode of a rail, i.e., multiple hobboing cutters 4 are arranged on same running track, so that
Track operation when there are also hobboing cutters 4 according to non-variable diameter after variable diameter.
During shield driving, when encountering the bottom end of high ground stress soft rock stress deformation, need to dig tunnel
When, pipe bending cylinder 3 continues working at this time, ejects periphery cutterhead module 2 respectively, is up to maximum digging diameter reaches design value
Only.To solve the problems, such as digging for high ground stress soft rock stress large deformation.And the hobboing cutter 4 on full circle cutterhead uses a rail multitool
Mode be arranged, i.e., multiple hobboing cutters 4 are arranged on same running track so that after variable diameter there are also hobboing cutter 4 according to unchanged
Track operation when diameter.
It is described in detail referring to 3 pairs of an attached drawing rail multitools of the invention, as shown in the cutterhead of the non-variable diameter of Fig. 3, in knife
A circular dashed line is decorated on disk, which indicates the operating path of hobboing cutter 4, checks that the path can clearly obtain and pacifies on the path
Equipped with two hobboing cutters 4, there are two the fortune that circular dashed line respectively represents hobboing cutter 4 being drawn on the cutterhead referring to the cutterhead after Fig. 3 variable diameter
Walking along the street diameter, is located at two hobboing cutters 4 in same path on the cutterhead of non-variable diameter, on two paths after being located at variable diameter, and becomes
A paths after diameter are identical as 4 path of hobboing cutter when non-variable diameter, therefore the present invention uses the multiple tool mode of a rail, so that after variable diameter
Cutterhead be located on the operating path before variable diameter there are also hobboing cutter 4, guarantee the rock breaking capacity of cutter.
Above-described two hobboing cutters 4 of setting on same path are not limitations of the present invention, simply by two
4 pairs of a hobboing cutter rail multitools of the invention are described in detail, because a rail multitool of the invention is meeting the rational deployment of hobboing cutter 4
On the basis of 3 or 4 each or more hobboing cutters 4 can be arranged on same path.
