The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, does not limit the utility model.
As shown in Figure 1, full face rock tunnel boring machine cutterhead described in the utility model comprises limit piece, central block, hobboing cutter, scraper bowl, slide quarrel groove, manhole, water spraying device, wearing plate, teeth, grille strip etc.Whole cutterhead comprises 2 central blocks and 4 limit pieces, and central block is eccentric separable type.For the ease of Assembling, the cutterhead piecemeal carries out when pre-assembled joining in process flange in factory and has bored bolt hole and pin hole, and field-installed connecting bolt and pin are provided.Central block 1,2 is connected with the limit piece, 4,5,6 be connected with alignment pin by bolt, behind the Assembling cutterhead is welded as a whole, and carries out nondestructive inspection and detect to guarantee its strength and stiffness; The cutterhead periphery arranges several scraper bowls 8 and slips quarrel groove 13, and broken rock quarrel is shoveled into scraper bowl at the bottom of the hole, and when scraper bowl 8 rotated to top with cutterhead, the rock quarrel was discharged into conveyor through slipping quarrel groove 13.Muck removal demand when scraper bowl and the quarrel groove that slips can satisfy maximum driving speed.The external surface of cutterhead is covered with chromium carbide or carbine abrasion-proof plate, to reduce in the wearing and tearing that can predict in the geological structure.In the utility model, slide on cutterhead quarrel tank sheet causes, with hold and guide quarrel stone to slip from the top of scraper bowl and water conservancy diversion to the main frame conveyor, at the cutterhead floor and slip on the quarrel groove, leave be used to the hole that leaks, make be cut moisture from, be beneficial to the conveyor muck removal.Scraper bowl 8 lips are equipped with removable teeth 11, and teeth 11 is fixed by bolts on the cutterhead.Teeth can be removed the ballast of cutterhead bottom fast, effectively.Grille strip 12 is arranged in the scraper bowl zone simultaneously, enters slide quarrel groove 13 damage conveyors to prevent or to limit large rock mass, guarantees that simultaneously the large scale sillar can not block or damage cutterhead.
As shown in Figure 1, water spraying device 9 and manhole 10 are set on the cutter head panel.When hobboing cutter 7 incision scars and the broken rock of roll extrusion, rock dust sprays everywhere from scar, and the temperature of hobboing cutter 7 is higher, rock quarrel is fallen into the dust of also kicking up at the bottom of the hole, for scar go out dirt and cooling cutter, arrange series of spray nozzles on cutterhead surface, suppress dust, cooling cutter with water spray.Nozzle is all used the resistant material manufacturing, and can change, be convenient to from cutterhead inside to safeguard, hydraulic pipeline adopts channel-section steel to protect.Several manholes 10 that dispose on the cutterhead, when driving with the capping of band hinge cover plate, during shutdown, capping can be opened to the cutterhead back, is convenient to personnel and object passes through.
Shown in Fig. 1～4, hobboing cutter 7 is installed in the tool rest that directly is machined on the cutter head panel by wedge yoke type structure, back loading type mounting means, its top meet knife face welding protection piece 14, can prevent effectively that the ratchel that falls from causing accidental damage to the hobboing cutter cutter ring.The hobboing cutter mount pad both can install 19 " hobboing cutter, can install 17 again " hobboing cutter.The hobboing cutter mounting means is wedge yoke type structure, back loading type.For avoiding the accidental damage of hobboing cutter cutter ring, above hobboing cutter, meet knife face welding protection piece.
Cutterhead adopts the design of panel type box-structure, keeps certain interval between cutterhead plane and the face, and broken quarrel stone can enter scraper bowl by the gap between cutter head panel and face; Reduce simultaneously outstanding from the cutterhead surface of hobboing cutter, be conducive to the starting in broken or loose stratum, reduced cutterhead to the disturbance on peripheral stratum.The planar section of cutterhead mainly works to stablize face when cutting rock.For guaranteeing that cutterhead has enough strength and stiffness, its front panel generally adopts the 200mm-350mm steel plate to be welded, and directly processes the hobboing cutter mount pad at steel plate, avoids the thermal deformation of adopting the welded type mount pad to cause.
The operating principle of cutterhead is described below: during the full face rock tunnel boring machine driving, the cutterhead rotation, cutterhead is under the effect of development machine propulsive force, one group of disk cutter incision rock, do the broken rock of concentric circular tracks rolling at rock face, the rock quarrel is fallen into by deadweight at the bottom of the hole, and scraper bowl scoops up the rock quarrel, and the rock quarrel falls into conveyor through slide quarrel groove and realizes muck removal.The water spraying device operation of constantly spraying water in tunneling process, the dust that suppresses to produce in the tunneling process also cools off cutter.Cutterhead design becomes single direction rotation, with the maximum that the realizes development machine ability of slagging tap, but also can backward rotation when getting rid of poverty at stifled slag.By bed hedgehopping limit cutter, this cutterhead can realize being not less than digging of 50mm.
Compared with prior art, the cutterhead that provides of the utility model has following beneficial effect:
1. cutterhead adopts the design of panel type box-structure, can play the effect of effective support face, and stable face is avoided landslide.
2. whole cutterhead is divided into 2 central blocks and 4 limit pieces, is connected with bolt by alignment pin between them, convenient transportation and installation.Simultaneously central block off-centre to minute, Effective Raise the rigidity of center cutter spacing.
3. front panel adopts steel plate and directly processes the hobboing cutter mount pad at steel plate, has avoided the thermal deformation because adopting the welded type mount pad to cause, has improved to greatest extent the cutterhead strength and stiffness.
4. the knife face welding hobboing cutter of meeting above hobboing cutter is protected piece, effectively prevents the improper damage of hobboing cutter.
5. the cutterhead tool rest both can install 19 " hobboing cutter, can install 17 again " hobboing cutter.
6. the opening part of scraper bowl is equipped with grid, can control the size that enters the cutterhead ballast.
7. leave on cutterhead floor and the muck removal groove be used to the hole that leaks make the quarrel moisture from, be beneficial to the conveyor muck removal.
Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from spirit and scope of the present utility model.Like this, if of the present utility model these are revised and modification belongs within the scope of the utility model claim and equivalent technologies thereof, then the utility model also is intended to comprise these changes and modification interior.
