Background technology
Such ground and milling machine is for example known by DE 196 31 042 C2 and DE 10 2,001 034662 A1, is quoted its disclosure hereby.Ground milling machine disclosed herein has frame, in frame, arranges and has the walking mechanism of totally four running gears.At running gear specifically finger wheel or pedrail mechanism at present, it may be also mixed form.In the ground milling machine known by above-mentioned prior art, at least two anterior running gears are configured to turn to.Another critical piece of this type of ground milling machine is the milling roller being bearing in frame, can milling underground by described milling roller.The common application of this type of ground milling machine is correspondingly exclude overlay, milling underground and/or underground is mixed with bonding agent, or milling underground is so that exploitation raw material.Accordingly, particularly road machine of this ground milling machine, is pavement milling machine, road-finishing machine, stabilizing machine or for exploiting the machine of raw material specifically, is surface miner specifically.Milling roller is totally substantially configured to cylindraceous and is parallel to and arranges transverse to operation or the direct of travel of ground milling machine with its rotation.In the time of work, milling roller rotates around its rotation, with suitable ground processing tool, is generally milling cutter and bores embedding underground.Milling roller is usually placed in the inside of the milling roller case being bearing in frame, to realize for example conveying of controlled milling material in milling roller region.
Conventionally there will be the working condition of the close as far as possible obstruction milling of hope.This situation especially frequently occurs in the time of road-surface milling, for example, in the time wishing near curb, house sidings operation or carry out similar milling and plane operation.The ground milling machine design in this reason with following characteristics is verified especially: milling roller is arranged to approach evenly and stop towards side with at least one end face and frame, and the running gear on this side can swing between the He Neibai position, outer pendulum position with respect to frame.By this arrangement, the running gear that at least one can be able to be swung is on the one hand brought into the position on the end face side of milling roller.In this outer pendulum position, preferably there are respectively two the end face sides being located axially at milling roller of a running gear at the rotation of milling roller, thereby realized the arrangement that running gear is stablized and can well be turned to especially.But then, pendulum position from this, at least one swingable running gear can also swing in the especially interior pendulum position before milling roller along operative orientation.Select so interior pendulum position, at least one the swingable running gear making can or only not obvious not protrude from frame towards side.In this side, below also referred to as zero side, milling roller almost flushes and stops with frame, thereby in the time that running gear is positioned at pendulum position, ground milling machine can be very closely in the other milling process of obstruction.
Therefore, the something in common of the ground milling machine of mentioned above and same-type of the present invention is the swingable running gear that has at least one to be connected with frame by slewing gear.Certainly such arrangement can cause, and is had greatly and also can be delivered to frame from swingable running gear via slewing gear by the required bearing capacity of running gear support frame.Therefore the slewing gear spy that main level moves conventionally will bear especially vertical force.The result causing is, the slewing gear of use must be constructed very solidly and be had resistance.Thereby cause cost of production raise, machine weight increase, and if turning course automation carry out, the device for revolving and driving that required power is larger.
Summary of the invention
Object of the present invention is now, a kind of possibility is provided, keep the described function of at least one running gear that can swing with respect to frame, and provide a kind of possibility, need not be so firm and weight is lighter thereby can realize, and aspect used drive unit comparatively economic slewing gear.
Described object is by realizing according to the ground milling machine described in independent claims with for the method that swings in and show of the running gear that makes ground milling machine.Preferred embodiment provides in the dependent claims.
Basic conception of the present invention is, in the time of work, the oscillating motion of described at least one swingable running gear separates with its bearing function in function.Particularly, be provided for the device of the bearing capacity load of slewing gear according to the present invention for this reason, described device is configured to, make at the interior pendulum of at least one swingable running gear and/or in putting position outward to set up shape in this running gear and frame sealed, for directly transmit bearing capacity between frame and running gear.Therefore this shape lock uint makes frame in the outer pendulum of described at least one swingable running gear and interior pendulum position, directly be carried by running gear, and walks around slewing gear.This shape lock uint is correspondingly configured to, at the sealed place of shape, frame, at least the major part of frame also directly loads on swingable running gear, therefore, even if exist, also only have sub-fraction bearing capacity via the slewing gear transmission that running gear is connected with frame.By this way, slewing gear can construct obviously light and structure without very firm, thereby therefore can make the lower-powered driver element for slewing gear.In the case of considering that common swing process to be described in detail below, slewing gear also needs to be configured with such soundness now, make it in swing process, can carry described at least one swingable running gear.This certainly than the frame of being born by running gear when ground milling machine transportation and the job run for example, together with being arranged on equipment on machine frame, conventionally having the weight quota of operation position, apparatus for work etc. light.Therefore, frame is directly born part weight by running gear rather than by slewing gear in interior pendulum and the outer pendulum position of described at least one swingable running gear by shape lock uint.
Can use multiple different form of implementation for the concrete structure of shape lock uint.Importantly, these forms of implementation all comprise two shape latch members interact with each other, and it is sealed that described shape latch members is configured for setting up at least one shape along a direction, particularly vertically acting on.And these two shape latch members can unclamp each other, thereby make that established shape is sealed can unclamp again.Particularly meet above-mentioned condition by the shape latch members each other with backstop.Therefore it is desirable to, for example shape lock uint has frame backstop in frame, and on running gear, has running gear backstop, these two backstops the interior pendulum of running gear and/or put outward position can unclamp ground mutually gear lean on, especially against each other.The feature of this form of implementation of shape lock uint is particularly its comparatively simple structure.Particularly preferably be, frame backstop and/or mobile devices limiting structure become adjustable, for example, by being arranged on the stop block on screw element, thus the optimum Match of assurance shape lock uint.
For important the passing through of the present invention bearing capacity transmission that shape that shape lock uint realizes is sealed must be able to realizing from described at least one swingable running gear to frame.Therefore for current embodiment also preferably, shape lock uint is configured to, and abuts in running gear backstop in the sealed mid frame backstop of shape.The feature of frame backstop is mainly, it is a part for frame.Here frame backstop is particularly directly made up of frame, or consists of the sealed plate of element, for example shape or the sealed tenon of shape that are fixedly connected with frame.Frame backstop preference is the groove in frame in this way.
Running gear backstop is a part for running gear or the element that is fixedly connected with it.It is desirable to, running gear backstop comprises the baffle plate that level is outstanding.
For according to the application of ground milling machine of the present invention, can adopt the multiple different concrete structure of running gear, wherein preferably use wheel or pedrail mechanism.Now advantageously verified, described at least one swingable running gear has the lifting column for carrying out highly adjusting with respect to ground in the face of milling machine.This structure of swingable running gear is known and is for example for example documented in the document about prior art above.In the structure of running gear with lifting column correspondingly with reference to these two pieces of documents.Running gear is arranged in frame for example height for the milling degree of depth by lifting column and regulates, and/or for example when a side of ground milling machine in milling groove face and the opposite side of ground milling machine in the time that milling groove face is advanced outward for the operation of running gear is highly carried out to level compensating.In addition described at least one swingable running gear is arranged on by lifting column the swing process that also makes described at least one swingable running gear put outside between He Neibai position, position in frame and becomes obviously easy.In this case, described at least one swingable running gear can raise by lifting column, can not swipe on the ground thus in swing process.Preferably running gear backstop is arranged on lifting column now, because described lifting column is in the interior pendulum of described at least one swingable running gear and outer pendulum position conventionally near positioning frame or very near frame.Shape lock uint itself can keep less by this way.
The structure of lifting column is also variable, wherein particularly preferably carries out elevating movement with cylinder piston unit.Lifting column also comprises protective sleeve conventionally, and described protective sleeve for example, for outwards covering driving element, cylinder piston unit.It is desirable to, running gear backstop is connected with the protective sleeve of lifting column, because particularly on this member, running gear backstop can arrange comparatively simply.
Running gear backstop can be designed to for example backstop groove or similar structures in principle.But when running gear backstop be from lifting column, supporting that especially lifting column protective sleeve is given prominence in a horizontal plane or baffle plate a part of time, can realize the comparatively simple structure of running gear backstop.Base plate be generally columned lifting column, be especially fixedly connected with its protective sleeve, and along continuous straight runs protrudes from lifting column.In other words, base plate forms a kind of stopper protrusion.Base plate is connected in the extra high mode of supporting capacity with lifting column, especially protective sleeve, thereby can effectively transmit bearing capacity by base plate to frame from lifting column.Here it is desirable to for example weld.
If described at least one swingable running gear comprises lifting column, slewing gear is preferably hinged on the lifting column of described at least one swingable running gear.Lifting column preferably has at least one for being connected to the holding plate on slewing gear for this reason.Now, holding plate is preferred for receiving at least one swing arm of slewing gear.According to preferably four link type slewing gear of the gyration slewing gear that can realize.When holding plate is simultaneously or when shape lock uint, especially running gear backstop a part of, can utilize best current assembly.Therefore in this embodiment, holding plate has dual-use function, both with the tie point that acts on slewing gear, is also used as the stop element of shape lock uint simultaneously.
Can adopt in principle such structure, wherein in the time that running gear is in He Neibai position, outer pendulum position, running gear backstop all abuts in position identical in frame backstop, sealed to form shape.Certainly frame backstop is preferably configured as, and makes frame backstop optionally provide respectively an independent stop dog position for outer pendulum position with for interior pendulum position.Frame backstop preferably correspondingly comprises interior pendulum backstop and outer pendulum backstop.Turning up the soil and be arranged in like this in frame in their spaces, running gear backstop in the time that running gear is in interior pendulum position is resisted against in interior pendulum backstop, and running gear backstop is resisted against in outer pendulum backstop in the time that running gear is in outer pendulum position.This embodiment especially can use such slewing gear, makes running gear all have identical direct of travel in He Waibai position, interior pendulum position, and therefore between these two positions, in horizontal plane, exists parallel staggering.Being convenient to like this design for the driving control system of the operation of travelling, is therefore favourable.
Such ground milling machine conventionally has the recess from zero side towards milling machine center oriented in the region of described at least one swingable running gear, if for example there is lifting column, lifting column is positioned in this recess in interior pendulum position.In addition this frame recess also supplement or alternatively for holding the parts of slewing gear and device for revolving and driving, for example cylinder piston unit.Interior pendulum backstop is preferably arranged on this now in the frame recess at milling machine center.Interior pendulum backstop is positioned at and on this position of ground milling machine, is convenient to engaging of interior pendulum backstop and running gear backstop, sealed to set up the shape of shape lock uint.
Can use the scope of slewing gear very extensive.Conventionally usage level swings slewing gear, especially four link type slewing gear.Slewing gear that can certainly usage space, the slewing gear in especially such space, it is except the horizontal hunting motion of at least one swingable running gear, can also realize the vertical adjustment of described at least one swingable running gear, for example, compensate to put outside the difference in height of the spacing to frame and ground between interior pendulum position simultaneously.Prove particularly preferably to be for this embodiment, interior pendulum backstop and outer pendulum backstop are to be spaced from each other in vertical direction layout.It is desirable to, separate with such spacing, this spacing is corresponding to put outside the difference in height causing between He Neibai position, position by slewing gear.
Shape lock uint can also change to some extent in other details.Preferably, frame backstop and running gear backstop are for example positioning auxiliary devices, be for example give prominence to and at the tenon of the sealed middle embedding opposed grooves of shape.By this way, all guaranteed that owing to putting outside He Neibai position, position shape is sealed, thereby improved operational reliability.Supplement or optional landform lock uint is designed to, make it vertically and horizontal direction to have realized shape between running gear and frame sealed.Like this, in this form of implementation, merely transmit bearing capacity except the shape by is vertically sealed, can also transmit along the power of horizontal plane effect.Here shape lock uint can be designed to, make shape lock uint there is respectively special shape latch members for the power of transmitting vertical and horizontal direction.But best, the shape latch members of shape lock uint is configured for transmitting the power of vertical and level between described at least one running gear and frame simultaneously.This utilizes such shape latch members to realize, described shape latch members has the sealed pin of vertically outstanding at least in part shape or stop pin on the one hand, and sealed in order to form shape, have another shape latch members, its form is interlocking mouth or the locking mouthful of the form of for example blind hole or through hole.
In addition, can also additionally imagine locking possibility, for example, additionally adopt locking device, described locking device to make to put outside position and/or interior pendulum locking position and the running gear of frame in shape is sealed.Such locking can realize by for example latch especially simply, and this latch preferably automatically inserts corresponding through hole, to fix the shape latch members of shape lock uint.In another preferred embodiment, shape lock uint also can be simultaneously for being locked in frame by slewing gear.In addition, supplement or can also be provided with alternatively separator, this separator is configured for realizing or auxiliaryly realizes that to cancel the shape of shape lock uint sealed.This is also preferably automatically to realize.Hydraulically powered lifting fork particularly for example can be set, and in the time of operation lifting fork, it assists by auxiliary two mutual vertical adjusting of shape latch members the separation that realizes shape latch members.
Monitoring system can be preferably set in addition, whether described monitoring system is for arriving outer pendulum position and/or interior pendulum position to described at least one swingable running gear, and to whether set up shape lock uint for bearing capacity is delivered to sealed monitoring of shape frame from described at least one swingable running gear, and for example trigger definite subsequent operation in response to this, for example trigger corresponding show and/or to the control automatically locking.
Another aspect of the present invention relate to a kind of for making ground the interior pendulum of the running gear of milling machine, ground milling machine especially recited above and the method for outer pendulum.For the advantage of utilizing the method according to this invention to realize is described, first common so far interior pendulum and the process of outer pendulum should be described.For this reason, the lifting column of described at least one swingable running gear, from an initial position such distance of at least retracting, no longer places on the ground running gear with its work plane.If always have four running gears, in this case, ground milling machine is still by totally three running gear supportings.Not being placed on ground described at least one swingable running gear next swings and enters pendulum Huo Waibai position, position in it.Last described at least one running gear again declines by stretching out of lifting column and is placed on ground and to pressing down with its work plane, thus a part of weight of its carrying milling machine.
Set now according to the present invention, interior pendulum or outside after pendulum, addedly sealed by set up direct shape between frame and running gear, and make bearing capacity transmission walk around slewing gear.Now, the foundation that shape is sealed is by shape lock uint, and especially foregoing shape lock uint is realized.The sealed vertically effect so particularly of such shape, is directly bearing on described at least one swingable running gear frame.Now in order to set up the sealed device for bearing capacity off-load with feature noted earlier that especially can adopt of shape.

The specific embodiment
Identical member represents with same Reference numeral in the drawings, but the member repeating in multiple figure does not mark separately in each figure.Fig. 1 a and 1b illustrate the top view of engineering machinery 1, wherein only show critical piece: frame, running gear, milling equipment and the device for bearing capacity off-load.For the sake of clarity save miscellaneous part, such as drive unit, operation position etc., they are shown in the lateral view of Fig. 1 c.Fig. 2 and 3 is phantom drawings of region observation from right front is oblique of the rear portion running gear of engineering machinery.The critical piece of machine frame only represents by a dotted line, so just can see the parts shown in Fig. 1 a and 1b with other visual angles according to emphasis.Fig. 4 a and Fig. 4 b relate to the subregion of engineering machinery equally, specifically machine frame be supported with the region of swingable running gear together with slewing gear.The extension of machine frame dots equally.
First describe the basic structure of ground milling machine 1 in detail by Fig. 1 a to 1c.The critical piece of ground milling machine 1 is frame 2 and is bearing in the milling equipment 3 in frame 2, and milling equipment has milling roller case 4 and is arranged on the milling roller 5 of milling roller case inside.In this specific embodiment, milling equipment 3 is arranged on the tail region of frame 2, and therefore it is the pavement milling machine of afterbody Barrate type specifically.In addition, ground milling machine 1 also comprises four running gears 6,7,8 and 9, and they are connected with frame 2 and frame 2 is bearing on ground 10 together with the element being bearing in frame.Running gear 6 to 9 comprises respectively an element with work plane, it can be for example crawler belt 11 as shown in Fig. 1 a, 1b, 2,3,4a and 4b, or can as shown in Fig. 1 c for example, be also active wheel 12, also may adopt mixed form here.Other critical element of ground milling machine 1 has the CD-ROM drive motor 13 not being shown specifically and in frame 2, is arranged on the operation position 14 above milling equipment 3.
Milling roller 5 is columniform processing tools, and its rotation R vertically extends in a horizontal plane and with operative orientation a.Operative orientation a refers to the direction of advance of ground milling machine 1 in the time of work operation.Milling roller 5 flushes and stops at a side of running gear 8 and 9 and the outer seamed edge of frame 2.This side is called zero side 15 below.The rear portion running gear 9 that is positioned at zero side 15 is bearing in frame 2 swingably.Specifically, it can swing between the interior pendulum position shown in the outer pendulum position shown in Fig. 1 a and Fig. 1 b in frame 2.
Running gear 9 is put outside in position and is parallel to another rear portion running gear 6 orientations about rotation R, and milling roller 5 is positioned between these two running gears 6 and 9.In this design of running gear 6 to 9, ground milling machine 1 is that privileged site is stablized and can well turn to.
On the contrary, running gear 9 in the interior pendulum position according to Fig. 1 b along operative orientation a inwardly towards milling machine center (about the width of ground milling machine 1) swing to milling roller 5 before, thereby ground milling machine 1 roughly evenly stops at the outer seamed edge of zero side and the end face of milling roller 5.In this position, ground milling machine can very closely carry out milling along obstruction in zero side.With reference to whole accompanying drawings, running gear 9 Fig. 1 a, 1c, 2 and 4a to 4c in be positioned at outer pendulum position, in Fig. 1 b and Fig. 3, be positioned at pendulum position.
For swingable running gear 9 can be moved between He Waibai position, interior pendulum position, this running gear is bearing in frame 2 by slewing gear 16.About the structure of slewing gear 16 and the details of operating principle particularly by the combination of Fig. 2 and Fig. 3 is observed to obtain.The critical element of slewing gear 16 is swing arm 17, leading arm 18, drive unit 19 and four hinge 20a to 20d, and they and running gear 9 and frame 2 be common forms four link type slewing gear.A main aspect of current specific embodiment is, slewing gear 16 is the slewing gears in space, and except running gear 9 is the position of horizontal plane changes, the vertical direction also realizing between He Waibai position, interior pendulum position regulates the height of running gear 9.For this reason, in the hinge 20c of the swing arm 17 in frame 2, guide chute is set.
