Need to set less knife spacing on cutterhead in stratum and arrange more cutter.The arrangement quantity of knife disc tool and cutter
The efficiency of construction and construction cost for directly affecting development machine are changed in installation.How more cutter and energy are arranged on cutterhead
It is enough quickly position, change and safeguard, it is that wide engineers and technicians need one of major issue urgently to be resolved hurrily.Cause
This, it is new problem anxious to be resolved to develop a kind of complete-section tunnel boring machine and directly push away back loading type cutter self locating device.
The content of the invention
The purpose of this utility model is that providing a kind of complete-section tunnel boring machine directly pushes away back loading type cutter self locating device,
The utility model is simple in construction, size is smaller, is easy to arrange more cutters on cutterhead, positions convenient, fast, reliable, energy
Enough effective cutter changing efficiency, improves efficiency of construction and utilization rate of equipment and installations.
What the purpose of this utility model was realized in：It is self-positioning that a kind of complete-section tunnel boring machine directly pushes away back loading type cutter
Device, including tool rest, upper voussoir, middle part voussoir, cutter, bottom voussoir, turnbuckle, clamping screw, top voussoir is pre-installed
Linked in tool rest and by turnbuckle, cutter is put into tool rest from tool rest interstitial hole, knife is installed on the voussoir of middle part
The cutter shaft of tool, at middle part, lower wedge portion installs bottom voussoir and middle part voussoir is fixed on tool rest with clamping screw, finally twists
Tight turnbuckle, cutter is fixed on tool rest by top voussoir and middle part voussoir.
The structure of the present utility model for being characterized by it.Its operation principle is, during Cutting tool installation manner；Top voussoir is filled in advance
In tool rest, turnbuckle is connected, cutter is advanced into tool rest from tool rest interstitial hole, middle part voussoir is installed to support cutter cutter shaft
Lower plane, install bottom voussoir, voussoir is locked on tool rest with clamping screw, turnbuckle is finally tightened, passes through top
Tool rest is secured firmly on tool rest on voussoir and middle part voussoir；When cutter is dismantled；Turnbuckle is unclamped, top voussoir is upward
Jack up to release the locking to cutter, remove clamping screw, middle part voussoir and bottom voussoir are removed out of tool rest, finally by knife
Tool pulls out inside tool rest and completes dismounting.
A kind of complete-section tunnel boring machine directly pushes away back loading type cutter self locating device compared with prior art, has structure new
Grain husk, convenient and swift, fixed reliability height is changed, the cutter changing time can be effectively reduced, so as to improve the utilization rate of equipment
And drivage efficiency, because physical dimension is smaller, therefore more cutters can be arranged on cutterhead, high rigidity rock stratum can be met to cutterhead
The advantages that requirement of pocket knife spacing, it will be widely used in complete-section tunnel boring machine technical field.
Brief description of the drawings
Below in conjunction with the accompanying drawings and the utility model is described in detail embodiment.
Fig. 1 is the structural representation of the present invention.
Fig. 2 is Fig. 1 A-A sectional views.
Embodiment
Referring to the drawings, a kind of complete-section tunnel boring machine directly pushes away back loading type cutter self locating device, including tool rest 1, upper wedge
Block 2, middle part voussoir 3, cutter 4, bottom voussoir 5, turnbuckle 6, clamping screw 7, top voussoir 2 is filled in tool rest 1 simultaneously in advance
Linked by turnbuckle 7, cutter 4 is put into tool rest 1 from the interstitial hole of tool rest 1, cutter 4 is installed on middle part voussoir 3
Cutter shaft, bottom voussoir 5 is installed in the bottom of middle part voussoir 3 and middle part voussoir 3 is fixed on tool rest 1 with clamping screw 6, is finally twisted
Cutter 4, is fixed on tool rest 1 by tight turnbuckle 7 by top voussoir 2 and middle part voussoir 3.
The operation principle that a kind of described complete-section tunnel boring machine directly pushes away back loading type cutter self locating device is cutter peace
During dress；Top voussoir 2 is filled in tool rest 1 in advance, turnbuckle 7 is connected, cutter 4 is advanced into tool rest from the interstitial hole of tool rest 1,
Installation middle part voussoir 3 installs bottom voussoir 5, voussoir 3 is locked at into knife with clamping screw 6 to support the lower plane of the cutter shaft of cutter 4
On seat, turnbuckle 7 is finally tightened, by the way that tool rest is secured firmly on tool rest 1 on top voussoir 2 and middle part voussoir；Cutter
