So, the handle 18a of rotating screw bolt 18 supporting station 15 is moved as fore-and-aft direction, and the handle 20a of rotating screw bolt 20 can make supporting station 15 do moving of left and right directions.
Moving up and down device descends the cutter 14 of cutter sweep 10 when doing rupturing operation.As shown in Figure 6, existing side by side on supporting station 15 is provided with two head trees 22, and its lower end is fixed with base bearing 23 and supported, and it is outstanding upward, the upper end of these two head trees 22 connects with junction plate 24, simultaneously, connects the mid portion of this two root post 22 with sleeve 25.
On above-mentioned junction plate 24 and sleeve 25 screw 24a, 25a are set, feed screw 26 runs through this screw 24a, 25a, does the installation of vertical direction.The large diameter top 26a of this feed screw 26 engages, remains in the upper side of junction plate 24, and simultaneously, the upper end is equipped with handle 27.Feed screw 26 is inserted in the screw 24a slidably, combines with screw 25a screw thread, and the rotation by handle 27 makes sleeve 25 liftings.
The cylindrical portion 25b of above-mentioned sleeve 25 both sides can be coated on the head tree 22 with being free to slide, is the shape of the central portion 25c with above-mentioned screw 25a between the cylindrical portion 25b of these both sides, is connected with above-mentioned device for revolving and driving on this central portion 25c.
That is, on one side of the front of central portion 25c, as shown in Figure 7, be equipped with drive division and carry the frame 25d of portion, on the other hand, be provided with the 25e of bearing portion that supports above-mentioned drive shaft 12 at its back pleurapophysis free to rotately.
Above-mentioned device for revolving and driving carries the V-shaped belt pulley 32 on the output shaft that prime mover 30, the driver 31 that is connected with the output shaft of this prime mover 30 is set on the frame 25d of portion, is installed on this driver 31 at described drive division.
On the other hand, on the 25e of bearing portion of an opposite side, support the upper end of drive shaft 12 free to rotately, and do the installation of vertical direction, and make the V-shaped belt pulley 33 of this drive shaft 12 of transmission do corresponding setting with above-mentioned V-shaped belt pulley 32, between these V-shaped belt pulleys 32 and 33, be wound with V-shape belt.35 be the belt wheel cap among the figure again.
Carry frame 25d one side at drive division and be provided with prime mover switch (not shown), open this switch, drive prime mover 30,, make drive shaft 13 by turning round shown in the direction of arrow among the figure by driver 31, V-shape belt 34.
Again, the axis 12a that is positioned at base portion side tool arm 13b downside be equipped with hook 37 on the position of process, on this hook 37 plummet 38 is installed.Utilize above-mentioned positioner to make cutter sweep 10 do moving of front and back and left and right directions, make plummet 38 be positioned at the top of center point P, thus, can make the axis 12a and the center point P centring of drive shaft 12.
In addition, drive shaft 12 and tool arm 13 are provided with cooling water path (diagram is omitted), and cooling water can be injected on the cutter 14 that cut off in the operation.
Secondly, the course of work of the cutter sweep of said structure is described.
At first, as shown in Figure 1, make vehicle 11 rest against manhole cover 1 near, then, open bonnet 11b, aftbody opens wide, and cutter sweep is fixed on the bearing surface that is formed by bonnet 11b and railway carriage rear end.
The length of the tool arm 13 of cutter sweep 10 and the angle of inclination that is installed on the cutter 14 on tool arm 13 tops preestablish accordingly with cutting off circle, but remake setting after also can be on being fixed in above-mentioned vehicle bearing surface.
Then, plummet 38 is hung on the hook 37, the handle 18a and the 20a of rotating operation positioner, mobile supporting station 15 makes plummet 38 be positioned at the top that cuts off circular center point P.Then, rotate the handle 27 of the feed screw 26 move up and down usefulness, make the diamond blade 14a of cutter 14 lower ends drop to the contact position of the circular C of cut-out of road surface R.
Then, start prime mover 30 and driver 31, make drive shaft 12 make horizontal rotation.Simultaneously, start oil cylinder 45, cutter 14 are pushed and straight ahead towards oblique inside direction.As shown in Figure 8, cutter 14 follow the revolution of drive shaft 12 to move along circumference, and the work of oil cylinder 45 simultaneously makes it move to depth direction, and the incision that its lower end is made up of diamond blade is carried out the toroidal cutting, cut off with cutter blade 14a road pavement.Difference according to cutting off the degree of depth makes cutter 14 move needed number of times along whole circumference, carries out the circle cutting of certain depth thus.
Above-mentioned incision is cut by the upper angled cut surface 14b of incision with cutting edge 14a with the circular inner peripheral surface that cutting edge 14a is cut off again, and along with near the top, is cut off circular diameter and increases gradually.
Again, when doing above-mentioned cut-out operation, supply with cooling water, spray cooling waters from the tool arm top to cutter 14 to cooling-water duct.The injection of this cooling water reduces the heating of diamond blade 14a and cutter 14 and wearing and tearing.
So the side face of the circular C of cut-out that is cut off by cutter 14 cuts off circular diameter and reduces the diameter minimum of the cut-out circle of lower side from upside to downside gradually as shown in Figure 9.Its result, the side shifting though the circular cut-off parts Ra in cut road surface can make progress, but to downside because of being subjected to stopping of the non-cut-out Rb of portion in road surface, can not move, the section of road surface circular cut-off parts Ra one side by the section of the non-cut-out in the road surface Rb of portion side under stop, thus, can avoid taking place the circular cut-off parts Ra in cut road surface and move and the state of affairs that falls to ground G, therefore, can take out the circular cut-off parts Ra in road surface after the cut-out easily.
Again, in the occasion of the cutter sweep of the 1st example, also inclined cut cutter 14 not, but as in the past, the vertical cut-out of carrying out the circular cut-off parts in road surface.
Below, describe with regard to the cutter of the 2nd example of the present invention.The cutter 14-A of the 2nd example shown in Figure 10 (A), (B), comprise the incision fixed cutter body 14c lower end with cutting edge 14a and the inclination of being fixed in the triangle on the cutter body at an upper portion thereof with cutting edge 14b '.
Cutter 14-A does not carry out the road surface cutting perpendicular to road surface R obliquely.Vertical the moving of cutter 14-A in cutting operation promptly can be undertaken by the decline of drive shaft 12, also can be undertaken by the work of oil cylinder 44.That is to say that the mobile drive deivce that cutter are moved towards the road surface incision is made of drive shaft 12 and/or oil cylinder 44.
In the occasion of carrying out the road surface cutting by cutter 14-A, move owing to cut the side face limit with cutting edge 14b ' limit by tilting, therefore, around the circular cut-off parts in road surface, form space corresponding to the shape correspondence that tilts to use cutting edge 14b '.Its result, even the circular cut-off parts in road surface moves and falls to the ground direction, also can be by the space that is formed at around the circular cut-off parts in road surface, the road surface circle cut-off parts after will cutting off is easily taken out from the road surface.Again, the inclination of cutter 14-A is a head end taper shape with cutting edge 14b ', so, road surface pavement is had excellent cutting ability, can not hinder the carrying out of road pavement cut-out because of the formed groove of coniform ledge 14b.
Figure 11 (A) is the variation example of the 2nd example (B), cutter 14-B has on the top of the cut surface 14b that tilts, it radially remakes stepped outstanding cut surface 14d, and the surface of the road surface pavement of shape is cut into the shape that is provided with stepped portion again so that be cut off coning.The cut-out that these cutter 14-B carries out road surface pavement as shown in figure 12.
Figure 13 (A) (B) is depicted as the cutter 14-C of the 3rd example, comprise: fixing road surface, the lower end of cutter body 14c is cut the cutting edge 14a of usefulness and is fixed in the radially outstanding stepped cutting edge 14d ' of cutter body 14c at an upper portion thereof, and the cut-out that these cutter carry out makes the face side of road surface pavement be cut off the shape that becomes to be provided with stepped portion.
The cutter 14-C of the 3rd example does not carry out the road surface perpendicular to road surface R obliquely to be cut off.
In the occasion of cutting off by cutter 14-C, as shown in figure 14, because be that move on cutting side face limit, limit, so, around the circular cut-off parts in road surface, form and the corresponding space SB of stepped cutting edge 14d '.Its result, even the circular cut-off parts in road surface moves, falls to the ground direction, also owing to be formed at circular cut-off parts space on every side, road surface, the circular cut-off parts in the road surface after will cutting off is easily taken out from the road surface.
Again, radially-protruding tool arm is made in self-driven main shaft lower end, is not limited to 1 shown in the 1-3 example, but the tool arm of another same structure can be set at the rightabout that for example differs 180 degree again.If make such structure, clipping time can be shortened.
Again, under the occasion of 1-3 example, move up and down device and use handle to turn round operation, make the sleeve lifting by feed screw, but also can use the motor prime movers.
As mentioned above as can be known, cutter according to cutter sweep of the present invention, cutter following drive shaft revolution when circumference moves, the section that cutter tilt cuts like the inner peripheral surface that digs the cut circle of hinge, by this, cut off circular diameter and reduce the cut-out round diameter minimum of lower side from upside to downside ground gradually.Therefore, though the circular cut-off parts in cut road surface can be moved upward, but because of being subjected to the side shifting downwards that stops of road surface non-cut-out portion, can avoid the circular cut-off parts in cut road surface to shift to the ground direction, avoid the generation of the state of affairs, its result can take out the circular cut-off parts in the road surface after cutting off easily from the road surface.
Again, if cut with the cutter road pavement that is provided with stepped section, then form around the cut-off parts steppedly, the circular cut-off parts in road surface is kept because of this stepped portion, can prevent from, can easily the circular cut-off parts in the road surface after cutting off be taken out from the road surface.
