In the invention, four stirring cutter heads are used for cutting four circular sections; one rectangular cutter head is used for cutting a rectangular section; the cut sections achieve 99% of requirements and do not have any cutting dead area basically; the cutting device has a small influence on ground; when used for box culvert construction, the cutting device is not easy to produce back land; and the cutting device has the advantages of simple structure and easy processing and manufacture.
Description
Technical field
What the present invention relates to is the topping machanism in a kind of tunnel construction field, in particular a kind of profiling rectangle topping machanism of push-bench.
Background technology
Push-bench is the equipment of the various pipelines in city and tunnel, culvert construction, and is generally in the majority with circular end surface.For the box culvert construction, requiring the cutting end face is rectangle, the rectangle end face is bigger than the cutting difficulty of circular end surface, subject matter is that the shape in cutting face can not satisfy full end face requirement, owing to can not accomplish full building up by welding, the pressure of front each point is inconsistent, can't realize earth pressure balance, easily causes the sedimentation or the protuberance on ground in the construction.
At present the cutterhead common form of rectangular top pipe machine is the combination of multitool dish, the combining form of four little cutterheads of the big cutterhead in the center that is generally+all around, and its cutting end face is the summation of several circular beater plate areas of cut, has certain cutting dead band.Another kind of rectangle Copying tool pan, its structure also is the big cutterhead based on the centre, the swing cutter that the cutting of Bu Zhiing all around is four jiaos links to each other the structure more complicated with big cutterhead by oil cylinder.
Summary of the invention
Goal of the invention: the objective of the invention is to overcome the deficiencies in the prior art, a kind of profiling rectangle topping machanism of push-bench is provided, by using eccentric drive shaft to make four independently to cut the rotation of stirring blade coiling eccentric drive shaft, form circular Cutting trajectory, drive the rectangle cutterhead by four eccentric drive shafts again and do the motion of sieve shape abrasive disk type, thereby form the cutting face of a rectangle.
Technical scheme: the present invention is achieved by the following technical solutions, the present invention includes the rectangle cutterhead, stir cutterhead, eccentric drive shaft, push-bench housing and power set, wherein: stir cutterhead and link to each other with eccentric drive shaft, eccentric drive shaft links to each other with power set, power set are fixed on the push-bench housing, rectangle cutterhead and eccentric drive shaft matched in clearance, rectangle cutterhead are positioned at and stir after the cutterhead.
Described stirring cutterhead has four, and the center of circle of four stirring cutterheads lays respectively at four summits of parallelogram.
Described four stirring cutterheads link to each other with four eccentric drive shafts of correspondence respectively.
Described rectangle cutterhead respectively with four eccentric drive shaft matched in clearance, the rectangle cutterhead is done the motion of sieve shape abrasive disk type under the drive of four eccentric drive shafts, thereby has formed a complete rectangle cutting face.
The present invention is the side's of comprising cutterhead axle sleeve, thrust bearing, bearing holder (housing, cover) and bearing also, wherein: square cutterhead axle sleeve and rectangle cutterhead fix, bearing holder (housing, cover) links to each other with square cutterhead axle sleeve, thrust bearing and bearing are located in the bearing holder (housing, cover), interstage sleeve is located on the thrust bearing, eccentric drive shaft and bearing and thrust bearing matched in clearance.
Described rectangle cutterhead is provided with preceding door, back door and positioning component, preceding door is positioned at the front portion of rectangle cutterhead, back door is positioned at the rear portion of rectangle cutterhead, and positioning component can be realized the axial location to the rectangle cutterhead between rectangle cutterhead and eccentrically weighted shaft.
Described rectangle cutterhead is provided with black box and seals.
The position of rotation of described rectangle cutterhead is provided with lubricating cup the rotation position is lubricated.
Operating principle of the present invention is: four independently cutting stir cutterhead respectively the eccentric drive shaft by separately drive by power set, can independently rotate around eccentric drive shaft, form the cutting end face of four circles, and play the guiding role, rectangle cutterhead of four common drives of eccentric drive shaft is done the motion of sieve shape abrasive disk type simultaneously, thereby form a complete rectangle cutting face, because be that four stirring cutterheads cut simultaneously, the inertia when having avoided a center cutter disc spins cutting causes the phenomenon of head rotation.
Beneficial effect: the present invention uses four stirring cutterheads to cut four circular cross sections, go out rectangular cross section by a rectangle knife cutting again, the cutting end face meets the requirements of 99%, substantially do not cut the dead band, influence to ground is little, as the box culvert construction, is difficult for producing back of the body soil, and simple in structure, processing and manufacturing is easy.
