The successful research and development of 19 cun of cutters and application are TBM(shield machines) major progress in part design process.The cutter ring of major diameter can increase the effective wear volume of cutter ring; improve the service life of cutter ring; reduce the number of times of tool changing and shut down the time changing cutter; improve the effective driving time; increasingly welcome by client, the design of major diameter TBM cutter is often used to the hobboing cutter of 19 or 20 cun (483 or 508mm).
Along with the increasing of cutter ring diameter, the size of cutter itself and weight also increase relatively big, and the rigidity of structure of tool rest and intensity to be also correspondingly improved, and the size of tool rest is also increasing, and its locus accounted on cutterhead is relatively big, and cutter spacing is the most increasing.Such as: the cutterhead of about 6m, 65mm can be designed into according to 17 cun of hobboing cutters, pocket knife spacing；According to 19 cun of hobboing cutters, pocket knife spacing 80mm to be designed into.
Utility model content
In order to solve above-mentioned technical problem, this utility model provides the circular girff of a kind of novel TBM, reduces 19 or 20 cun of hobboing cutters locus on cutterhead, reduces cutter spacing, improves the rock breaking capacity of cutterhead, and reliable lock, removes and installs conveniently.
In order to achieve the above object, the technical solution of the utility model is: the circular girff of a kind of novel TBM, including circular girff, it is provided with tool rest in girff, tool rest is provided with hobboing cutter, described tool rest is provided with c-type block, c-type block is provided with the cutter shaft of hobboing cutter, and cutter shaft is provided with wedge, and wedge is connected with tool rest by turnbuckle, turnbuckle is provided with tension block and nut, and tension block is connected with tool rest by turnbuckle by nut.
Described c-type block is connected with tool rest by connecting bolt, is provided with pad between connecting bolt and tool rest.
Described c-type block is the surface bloom through Overheating Treatment.
Described tool rest is provided with two, and tool rest is symmetricly set on the two ends of girff.
Described tool rest and girff are integrated.
This utility model uses circular girff, compared with traditional rectangle girff, decreases large diameter disc cutter locus on cutterhead, reduces cutter spacing, make the stress of girff evenly, add the stability of hobboing cutter, improve the rock breaking capacity of cutterhead；The cutter shaft of hobboing cutter is arranged on c-type block, c-type block is fixed on tool rest, the opposite side of cutter shaft is fixed by tension block and wedge by being connected on girff, the locking making hobboing cutter is more reliable, have only to remove tension block during dismounting and hobboing cutter can be taken out by wedge, it is achieved that remove and install convenient purpose.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not paying creative work premise, broadly fall into the scope of this utility model protection.
As shown in Figure 1, Figure 2 and Figure 3, the circular girff of a kind of novel TBM, including circular girff 1, it is provided with tool rest 10 in girff 1, tool rest 10 is provided with hobboing cutter 8.Compared with traditional rectangle girff, circular girff 1 decreases it and takes up space, and reduces cutter spacing, and circular configuration makes the stress of whole girff evenly simultaneously, improves the stability of girff.Tool rest 10 is provided with two, and tool rest 10 is symmetricly set on the two ends of girff 1, for the weight of load-bearing hobboing cutter 8.Tool rest 10 and girff 1 are integrated, i.e. use casting or forging by achievements machine-shaping.
Tool rest 10 is provided with c-type block 7, and c-type block 7 is the surface bloom through Overheating Treatment, improves the hardness on its surface.C-type block 7 is connected with tool rest 10 by connecting bolt 5, is provided with pad 6, connecting bolt 5 and pad 6 and is stably fixed on tool rest 10 by c-type block 7 between connecting bolt 5 and tool rest 10, can be dismantled easily by connecting bolt 3, be changed c-type block 7 simultaneously.C-type block 7 is provided with the cutter shaft 11 of hobboing cutter 8, and the C-shaped configuration of c-type block 7 is that the circular configuration according to girff 1 is arranged, and facilitates the installation of cutter shaft 11, saves space simultaneously.Cutter shaft 11 is provided with wedge 2, wedge 2 and c-type block 7 and lays respectively at the both sides of cutter shaft 11, for cutter shaft 11 is stably fixed to tool rest 10.Wedge 2 is connected with tool rest 10 by turnbuckle 4, and turnbuckle 4 other end is provided with tension block 3 and nut 9, and tension block 3 is connected with tool rest 10 by nut 9, thus is fixed wedge 2 by turnbuckle 4.Tension block 3 can be connected in girff 1, it is achieved fixing wedge 2.The c-type block 7 of girff 1, wedge 2, tension block 3, about the centrosymmetry of girff 1, facilitate the installation and removal of hobboing cutter 8.
As shown in Figure 4 and Figure 5, the cutter shaft 11 of hobboing cutter 8 is dismantled from the back of girff and is installed, during dismounting, first nut 9 is taken out, tension block 3 is taken out from girff 1, then turnbuckle 4 and wedge 2 is taken out, then hobboing cutter 8 is rotated a certain angle, make cutter shaft 11 depart from tool rest 10, hobboing cutter can be taken out；May then pass through and unclamp connecting bolt 5 and pad 6, c-type block 7 is taken out, it is achieved the replacing of c-type block 7.During installation, tilted by hobboing cutter 8 puts into girff 1, is then placed on c-type block 7, is fixed by cutter shaft 11 by wedge 2, and tension block 3 is connected on girff 1, utilizes tension block 3, turnbuckle 4 and nut 9 to be fixed by wedge 2.
The above; it is only this utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; any those familiar with the art is in the technical scope that this utility model discloses; the change that can readily occur in or replacement, all should contain within protection domain of the present utility model.
