Description
The present invention relates to be construct have polygon, the most desirable be the shield type excavator that the tunnel, grottoes, groove etc. of quadrangle section configuration use.
For for constructing the square frame shape shield type excavator that tunnel with polygon section configuration, grottoes, groove etc. use, be to wish that it can neatly and not form arcuation when polygonal each corner part of digging.
As one of this square frame shape shield type excavator, have to use and have towards becoming the 1st direction of orthogonal to stretch out with the axis of the shield structure body of square tube shape and several cramp bars that can move back and forth towards the 2nd direction with the axis orthogonal of the 1st direction and shield structure body and some cutters of installing on each cramp bar have the set of knives zoarium; This cutter is that a pair of drill bit that will stretch out to the 1st direction is the end (spy opens flat 1-310089 communique) that cutter head is contained in the 2nd direction.This development machine is to drive each cutter by the reciprocating motion towards the set of knives zoarium of the 2nd direction to have and move back and forth and digging excavation face.Yet on this development machine, cutter is on the 1st direction the cutter head of adjacent cutter to be disposed mutually continuously, so just as with plane planing wood material, but be that excavation face integral body is cut, drivage efficiency is not high.
Another kind of frame type development machine, be to use to cylinder that around axis, can rotate that stretches out with the axis orthogonal direction of the shield structure main body of square tube shape and the set of knives zoarium (spy opens flat 2-66295 communique) formed at some cutters that the outer peripheral face of this cylinder is installed with.This development machine is to rotatablely move digging excavation face by what rotatablely moving of cylinder drove cutter.Yet, this well-known development machine, the major part of the leading section of its shield structure body all by the cylinder locking, so it is few to enter the intrinsic native sand amount of shield structure, drivage efficiency is not high.In addition, the native sand of this well-known development machine institute digging is because the rotatablely moving all by rake to a side, so just need bigger driving force of cutter.
Also has a kind of frame type development machine, be to use by the several arms that stretch out towards fore-and-aft direction and can rotate angularly around the axis that extends with the 1st direction of the axis orthogonal of the shield structure body of square tube shape, the set of knives zoarium (No. the 3711159th, United States Patent (USP)) that cramp bar that is installed with leading section at this arm and stretches out towards the 1st direction and the some cutters that are installed with on this cramp bar are formed.This development machine is that the oscillating motion by arm and cramp bar drives cutter and moves back and forth digging excavation face.Yet on this development machine, the set of knives zoarium can be moved just must push the native sand that is full of digging open in order to protect caving in of excavation face, so drive the fit driving force that just need be very big of set of knives.
The object of the present invention is to provide drivage efficiency height, driving set of knives zoarium not to need the very shield type excavator of large driving force.
Shield type excavator of the present invention, comprise tubular shield structure body with polygon section configuration, the set of knives zoarium of the leading section of note matter structure body before can reciprocatingly being configured in towards the 1st direction of reporting to the leadship after accomplishing a task with the axis of aforementioned shield structure body should be arranged at least and drive the driving mechanism of this set of knives zoarium.
Before note set of knives zoarium, be the some zigzag cutters that disposing with interval and stretching out towards preceding note the 1st direction towards the 2nd direction of reporting to the leadship after accomplishing a task with the axis and preceding note the 1st direction of preceding note shield structure body from the leading section of preceding note shield structure body; In the some tabular cutter that is disposing with interval towards preceding note the 1st direction with leading section and stretching out, select some cutters to form towards preceding note the 2nd direction at preceding note shield structure body.
When the set of knives zoarium was equipped with jagged cutter, the set of knives zoarium moved back and forth towards the 1st direction when development machine advances, thus by the advancing and the effect that moves back and forth of set of knives zoarium of development machine, each jagged cutter then as saw digging excavate face.So the excavation face then is divided into many fragments by jagged cutter.
When the set of knives zoarium was equipped with tabular cutter situation, the set of knives zoarium moved back and forth towards the 1st direction when development machine advances, so by the advancing and the effect that moves back and forth of set of knives zoarium of development machine, each tabular cutter is digging excavation face then.So the excavation face is divided into many fragments by tabular cutter.No matter in what situations above-mentioned, divided fragment is linked in the shield structure body through the space between the adjacent cutter along with development machine advances.Secondly, be linked into the intrinsic native sand of shield structure, then, be discharged to outside the development machine at last by various discharge means.
As mentioned above, according to the present invention, at least the set of knives zoarium that moves back and forth in the 1st direction, be the some zigzag cutters that extend to the 1st direction with interval from towards the 2nd direction, with in the some tabular cutter that the 2nd direction is extended, select some cutters to form with interval in the 1st direction, so the excavation face is to be divided into many fragments by many cutters, the driving force that drivage efficiency height, cutter are used also needn't be very big.
Before note set of knives zoarium, it would be desirable some zigzag cutters of note before being equipped with and the some tabular cutters of preceding note that link with adjacent preceding note zigzag cutter.Like this, by advancing and the effect that moves back and forth of set of knives zoarium of development machine, each zigzag cutter then moves digging excavation face as saw, each tabular cutter is then with action digging excavation face like hammer or the spade, so the excavation face is divided into many fragments by the zigzag cutter, simultaneously, also be divided into many fragments by tabular cutter.Consequently with zigzag only is housed or tabular set of knives zoarium is compared, the driving force that drivage efficiency height, cutter are used is also available forr a short time.
The cutter head of preceding each cutter of note at least can be towards the place ahead.In this case, the mechanism that moves of each cutter of note before preceding note driving mechanism it would be desirable and can make, Yi Bian so that the cutter head of preceding each cutter of note at least towards the place ahead displacement, Yi Bian towards side's displacement of preceding note the 1st direction; And on one side towards the rear displacement, on one side towards the opposing party's displacement of preceding note the 1st direction.Like this, during of the opposing party displacement of the cutter head limit of cutter, then cut in the excavation face towards displacement limit, the place ahead towards the 1st direction; When the opposing party displacement of limit towards displacement limit, rear towards the 1st direction, then make it to leave, move from the excavation face, so each cutter in the incision excavation face is just very strong, available small driving force digging excavation face.
Preceding note driving mechanism it would be desirable and is equipped with: at the drive source of preceding note shield structure body configuration; Around the axis that preceding note shield structure body stretches out towards preceding note the 2nd direction, can dispose, have the bent axle of eccentric part rotatably at both ends; The rotation of preceding note drive source is remembered the transmission mechanism that turns the axle transmission forward; Preceding note eccentric part corresponding respectively a pair of rocking arm, an end remember eccentric part by rotatably mounted corresponding before, his end and binding of preceding note set of knives zoarium.With such driving mechanism, to compare with the jack that drives with piston, oil cylinder mechanism, the cutter that can improve in the unit interval moves back and forth number of times, can more effectively carry out digging.Secondly, the cutter head of each cutter is to describe circular trace by the eccentric motion that the set of knives zoarium carries out, so each cutter is to move like more effectively piercing towards the excavation face, so it is also bigger to make the cutter that enters the excavation face hob effect.
Also should load onto connecting rod to preceding note driving mechanism: before can being configured in rotatably angularly around the axis that the one end is extended towards preceding note the 2nd direction on the note shield structure body; The other end then remember forward axis that the 2nd direction is extended around can be attached at rotatably angularly before on the note set of knives zoarium.Like this, the cutter head of each cutter is when direction moves forwards, backwards, each cutter also produce move back and forth towards the 1st direction like motion, so improved drivage efficiency.
In the 1st direction, remember the point of contact position of the preceding note connecting rod of set of knives zoarium forward, preferably remember the opposing party's displacement of the 1st direction forward from the point of contact position of the preceding note connecting rod of remembering shield structure body forward.If use such driving mechanism, in conjunction with rotatablely moving of taking place owing to crankshaft rotating, Yi Bian the displacement at least forwards of the cutter head of each cutter, Yi Bian remember side's displacement of the 1st direction forward; And during displacement rearward on one side, on one side towards the opposing party's displacement of preceding note the 1st direction, so each cutter can be made it mobile exactly with simple mechanism.
In desirable embodiment, should include preceding note shield structure body interior zoning is the dividing plate in the place ahead district and rear district.At this moment, the native sand that is come out by digging then inserts the place ahead district from material receiving port.
The rear of note set of knives zoarium before being disposed at and the stone breaker by preceding note drive mechanism also should be arranged, enter between this stone breaker and the preceding note dividing plate or this stone breaker and preceding note shield structure body between native sand in gravel, will be broken jointly by stone breaker and preceding note dividing plate or preceding note shield structure main body.Like this, the gravel in native sand just can not harm the discharge of native sand.
Also should load onto the pair of pipes that enters the native sand in preceding note the place ahead district for discharge, preceding note the place ahead district preferably is provided with Room the 1st and Room the 2nd, the native sand of note before Room the 1st is accepted, note stone breaker body before disposing, Room the 2nd is by accepting the 1st indoor soil sand between preceding note stone breaker body and the preceding note shield structure body and between preceding note stone breaker and the preceding note dividing plate, and is communicated with aforementioned tube.Like this, excavation face soil pressure is transferred to dividing plate by the native sand that is full of in Room the 1st, utilizes so Room the 2nd can be used as the muddy water chamber.
Before note shield structure body can by preceding note the 1st direction with interval vis-a-vis a pair of the 1st external and preceding note the 2nd direction with interval vis-a-vis a pair of the 2nd external to form be the section configuration of square in essence.
The 2nd body of remembering the 1st body of set of knives zoarium before disposing and being disposed at the rear of the 1st body is housed on the preceding note shield structure body.Before note the 1st and the 2nd body, be to make it linking movably towards direction close or that leave by four corresponding respectively jack of that disposing and four turnings preceding note square on preceding note shield structure body.Like this, although be that the development machine of square also can be revised direction of advance.
On in desirable embodiment, the axis of preceding note shield structure body and preceding note the 1st direction and the mutual orthogonal of the 2nd direction.Also have, in desirable embodiment, development machine remembered in the past the axis direction of shield structure body and preceding note the 2nd direction in horizontal direction attitude be used.
Most preferred embodiment of the present invention is described with reference to the accompanying drawings, wherein:

With reference to Fig. 1-4, the shield type excavator 10 of square include the square tube shape shield structure body 12, be located at dividing plate 14 on this shield structure body, the driving mechanism 16 that supporting by this dividing plate and moved back and forth the set of knives zoarium 18 of digging excavation face by this driving mechanism in the 1st direction (illustrated example is an above-below direction) with the axis orthogonal of shield structure body 12.
Transmission by figure goes up some side's tube-shaped tubes 26 that thrust that the thrust generating apparatus of unshowned propulsion plant class produces pushes by the digging track along development machine 10 is advanced shield structure body 12.Yet, also can use as thrust generating apparatus for example to be configured in shield structure body and to construct between the lining cutting that the digging track is built and with some jack of preceding note lining cutting as the counter-force body.During as the some propelling jack of counter-force body, these jack also can be also used as the adjustment in direction jack with lining cutting in use.
The inside of the 1st body 20 is the place ahead district 28 of excavation face side by dividing plate 14 zonings and keeps atmospheric rear district 30 at its rear.The place ahead district 28 is the i.e. Room 34 the 1st, waste chamber of accepting the native sand that digging comes out by grid 32 zonings, and the muddy water chamber that is being connected with rear end lower in Room the 1st i.e. Room 36 the 2nd.Room 36 the 2nd is at the rear of Room 34 the 1st, is forming in the bottom of shield structure body 12.The pipe 40 that continues in Room 36 the 2nd and to supply with pipe 38 that muddy water uses and native sand and muddy water are discharged together.
As shown in Figure 5, bent axle 46 is the tops that extend in Room 36 the 2nd along left and right directions, is being supported by dividing plate 14 at the both ends of bent axle main part by bearing 54 and shell 56.Each Rocker arm 50 is being supported by the eccentric part of corresponding bent axle with it by bearing 58 and shell 60.Between shell 56,60, dispose mechanical seal 62.Shell 60 is equipped with and covers 64.Dispose various encapsulants on the shell 56,60, in shell 56,60, also be filled with lubrication oil.
Set of knives zoarium 18 is configured in the leading section of shield structure body 12.Can not make angle rotary ground around the axis that preceding note the 2nd direction is extended in the first end parts of first end, its top and the connecting rod 42 of its underpart and Rocker arm 50 is linking.As shown in Figure 2, from above-below direction, the point of contact of the connecting rod 52 that links with set of knives fit 18 is compared with the point of contact of the connecting rod 52 that links with shield structure body 12 and dividing plate 14 and is positioned at the top.
Be equipped with on the set of knives zoarium 18 at left and right directions extended jagged some cutters 66 of universe above-below direction and the some tabular union body 68 that extends to left and right direction with interval and adjacent cutter 66 is being linked mutually at above-below direction with interval.
Each cutter 66 is moved when making it digging excavation face in preceding note the 1st direction, and drill bit is that cutter head 70 is to be oblique upper towards the place ahead and top.The material receiving port of native sand in each union body 68 and adjacent cutter 66 common regulations, and cutter 66 is to dispose by the little pitch P of eccentric amount e than the eccentric part of bent axle 46.
Each union body 68 is the level of state and is fixed on the adjacent cutter 66.Each union body 68 is tabular cutter in illustrated example, is that cutter head 72 is the leading edge ends that are positioned at main part so link the drill bit that is extending at left and right directions.The cutter head 72 of each tabular cutter 68 is to be oblique upper towards the place ahead and top.
Between dividing plate 14 and set of knives zoarium 18, disposing rubble body 74.Rubble body 74 from the rear of set of knives zoarium 18 to the adjacent zigzag cutter 66, can not be attached at movably on Rocker arm 50 and the zigzag cutter 66.It is that cutter head 76 places front-end edge portion that rubble body 74 will extend towards the drill bit in the place ahead at left and right directions continuously.
When development machine 10 makes bent axle 44 rotations by drive source 44, then the eccentric part of bent axle 46 rotates towards the direction of arrow of Fig. 2 around the axis of bent axle 46, so Rocker arm 50 carries out swing movement around the eccentric part of bent axle 46, set of knives zoarium 18 is moved back and forth at above-below direction with connecting rod 52.
For this reason, development machine 10 is when drive source 44 is driven under bearing the state of thrust, fit 18 configuration sections at zigzag cutter 66 of set of knives are moved back and forth at above-below direction in the scope more than the P, so because the advancing and the effect that moves back and forth of set of knives zoarium 18 of digging machine 10,66 on each jagged cutter is as digging excavation face the saw, and face is excavated in digging 74 of each tabular cutter 68 and stone breaker as scoop or the spade.
So, by the some grooves that extending of zigzag cutter 66, so the excavation face is divided into many fragments by zigzag cutter 66 in the above-below direction formation of excavation face.Divided fragment is divided into more fragment once more by tabular cutter 68 and rubble body 74.Divided once more fragment along with advancing of development machine 10, enters Room 34 the 1st from the material receiving port by zigzag cutter 66 and union body 68 regulations.
The native sand that the native sand that is come out by digging is full of the 1st chamber interior 28, the 1 chamber interior 28 is access in Room 36 the 2nd through between the 1st body 20 and the rubble body 74 or after between dividing plate 12 and the rubble body 74 by grid 32.Native sand in 36 inside, Room the 2nd by managing 38 with the muddy water of supplying with Room 36 the 2nd, is discharged the outside to development machine 10 from Room 36 the 2nd by pipe 40 again.The pressure in the place ahead district 28 is by pressure meter 78 instrumentations, for preventing to excavate the numerical value that the face slump should maintain regulation.
Cut apart the gravel that contains in the fragment of back again, in the time of between by the 1st body 20 and rubble body 74 or between dividing plate 12 and the rubble body 74, along with the reciprocating motion of rubble body 74, to the 1st main part 20 or dividing plate 14 extruding, being broken into can be by the size of grid 32 by rubble body 74.Drive source 44 is reversed often to improve the crushing effect between rubble body 74 and the 1st body 20.
The configuration section of zigzag cutter 66 should be apart from P below the eccentric amount e of eccentric part of bent axle 50.It is desirable to:
e＝P～3P
Better data are:
e＝P～1.5P
When the arrangement pitch P of zigzag cutter 66 was bigger than e, the motion track of adjacent zigzag cutter 66 can be continuous, so can not form continuous groove towards the 1st direction on the excavation face.On the contrary, the arrangement pitch P of zigzag cutter 66 such as when too small, then zigzag cutter 66 is also little, and the mechanical strength of zigzag cutter 66 is also just little.
The size of the cutter head 72 of left and right directions, preferably the gauge than the main part of zigzag cutter 66 is big slightly.Like this, moving back and forth of zigzag cutter 66 just can be slick and sly.
Using development machine 10 is the excavation face to be divided into many fragments by zigzag cutter 66, tabular cutter 68 and rubble body 74 carry out digging, so compare the drivage efficiency height with any development machine in the past.Also have, zigzag cutter 66 is to move in the digging groove that is formed by self, so the driving force that cutter is used needn't be very big.
As development machine 10, the set of knives zoarium is to be made it to move back and forth by rotatablely moving of bent axle 46, compares with the jack that uses piston, oil cylinder mechanism, and the cutter that can improve in the unit interval moves back and forth number of times, can carry out digging more efficiently.The cutter head that makes each cutter with the eccentric motion of describing round track around the axis orthogonal of shield structure body 12, the axis that extends in the horizontal direction, undertaken by set of knives zoarium 18, so can make zigzag cutter 66 and tabular cutter 68 pierce in the excavation face like motion, so zigzag cutter 66 and tabular cutter 68 in the excavation face to hob effect be very big.
In order to replace that the upper end of set of knives zoarium 18 is attached on shield structure body 12 or the dividing plate 14 by connecting rod 52 pivotings, also regulation set of knives zoarium 18 such as available saddle moves back and forth.
Yet, when being attached at shield structure body 12 or dividing plate 14 on by connecting rod 52 pivotings the upper end of set of knives zoarium 18, and to compare with occasions such as saddles, driving mechanism 16 can be simple.Also have, the cutter head of each cutter can the limit forwards, backwards direction move, the motion that moves back and forth in the 1st direction is so can improve digging efficient.
Particularly, the position of connecting rod 52 points of contact on the set of knives zoarium 18 in above-below direction preferably can be from the point of contact displacement downwards of the connecting rod 52 on dividing plate 14 and then the shield structure body 12.If with such driving mechanism, combine with rotatablely moving of rotation generation by bent axle 46, the point of contact of the connecting rod 52 on set of knives zoarium 18, then as shown in the arcuation arrow of both direction, carrying out displacement on Fig. 2, so displacement upward when making the cutter head displacement forwards of each cutter at least, and displacement downwards in the time of displacement rearward, each cutter can enough simple mechanisms make it to move reliably.
During zigzag cutter 66 diggings excavation face, acting on counter-force on shield structure body 12, the counter-force of this moment is the power that shield structure body 12 is pressed down, so the direction of advance of development machine 10 is because the danger that counter-force is changed is few.
Relatively during the change in location of the development machine 10 of plan reference line, when the direction of advance of development machine changes, and during with the direction of advance change of development machine, can revise by adjustment in direction jack 24a, 24b, 24c, 24d.
When the direction of advance of development machine 10 is revised to left and right direction, for example reach (B), jack 24a, 24b are extended (or contraction), or jack 24c, 24d contraction (or elongation) is got final product at Fig. 6 (A).24a, 24b can also be extended (or contraction), and simultaneously jack 24c, 24d contraction (or elongation) also can.
With the direction of advance of development machine 10 towards upper and lower when revising, for example and (B),, or jack 24b, 24c shunk (or elongation) get final product jack 24a, 24b elongation (or contraction) at Fig. 6 (A).Can also and simultaneously jack 24b, 24c be shunk (or elongation) with jack 24a, 24d elongation (or contraction).
Also have, with the direction of advance of development machine 10 when the dimetric diagonal correction, for example reach (D), make under the flexible state of jack 24a, 24c, shrink (or elongation) with jack 24b contraction (extending) and with jack 24d and get final product at Fig. 6 (C).Like this, carry out angle rotation for the 2nd body 22 around diagonal 80 by the 1st body 20, the 1st body 20 forms tilt angle theta for the 2nd body 22, so can will revise at the yaw of arrow 82 directions.
Above-mentioned adjustment in direction technology is not only to development machine 10, and also can be suitable for well-known square shield type excavator technology in the past.Shield structure body also can not be divided into the 1st and the 2nd body in this case, but the jack that advances usefulness also dual-purpose be the adjustment in direction jack.
In addition, in order to replace utilizing development machine 10 to make the direction that moves back and forth of zigzag cutter 66 become above-below direction, also can utilize development machine 10 to make the direction that moves back and forth of zigzag cutter 66 become left and right directions roughly to revolve the state that turn 90 degrees around its axis; When constructing the grottoes etc. of direction up and down or oblique extension, also may make development machine direction or oblique advancing up and down.Can be the sphere of movements for the elephants type or the matrix type overlay configuration gets final product with several development machines 10 when constructing large tracts of land tunnel etc.
The present invention is not only the development machine with square cross-section shape, also goes for having hexagon, the development machine of other polygonal section configuration such as octagon.
