Description

Be used for during crossing, the surface that is laid on the rail in track being carried out the equipment of grinding and being used in the grinding rack in this equipment

Technical field

The utility model relates to a kind of being used for the grinding rack that the equipment of grinding is used is carried out in the surface that is laid on the rail in track.

Background technology

Be laid on rail in track because that run at high speed and/or heavy continual the crossing of vehicle suffers obvious wearing and tearing.This wearing and tearing at first often show and form the line trace or form ripple and the structure fine crack.If by regular maintaining, do not eliminate this wearing and tearing, these wearing and tearing may continue development and cause the grievous injury of rail and like this safety of later rail transport formed to serious danger so, until the danger that causes rail to fracture and the derailing that causes thus.

In order to prevent such danger and to eliminate wearing and tearing or repair the rail of wearing and tearing and the rail worn and torn is carried out to shaping again, as a kind of possible method, the surface of rail, particularly tread and the seamed edge that travels are carried out to grinding now.This grinding is used in modern fastlink especially, as the bullet train (TGV) of the inter-city train by German (ICE), France or the fastlink that crosses of the Shinkansen of Japan.Because implement on the rail of this grinding in being laid on track, for such reclamation activities certainly can not specially be pulled down these rails and carry out regularly grinding in the grinding workshop from track, so typically apply so-called grinding car for this reason.This grinding car has the grinding tool remained in grinding rack structure is set, and these grinding tools arrange structure and drop on the rail surface and on this rail surface and move directedly.There is such grinding rack at this, drive the grinding tool rotation in these grinding racks, that is, grinding tool active rotation ground is pressed to rail cover and produces there grinding.This grinding car during grinding with slow speed (order of magnitude be to the maximum 10 kms/hour fltting speed) travel forward.

In EP0708205A1 to a kind of alternative method and for this reason a kind of and equipment or grinding car design are described.Grinding tool is symmetrically constructed and is rotated freely around the grinding tool rotation there, and by motor or similar drive unit, does not drive and form such rotation.Now, the grinding car travels forward together with the grinding tool that drops on the rail surface and press this rail surface, wherein, grinding tool is adjusted into their rotation and rail and vertically acutangulates, the surface that is driven in rotation by relative motion like this and brings into play ablation and correspondingly machine away the wearing and tearing of rail at this.In this technology, the grinding car travels forward with obvious higher speed, can obtain herein about 80 kms/hour speed.

In two kinds of described methods, grinding tool produces very large wearing and tearing, and these grinding tools need to correspondingly regularly replace.This wearing and tearing particularly in the end describe according to high especially in the method for EP0708205A1, thereby need within the short time interval, change grinding tool especially at this.

In order at this, to make constantly the grinding car stop for grinding tool changes, grinding rack correspondingly is configured with and keeps beam (Haltebalken), is fixed with at least two grinding tools at the longitudinal axis of this maintenance beam relatively in being offset the position of an angle on this maintenances beam structure is set.Described maintenance beam can reverse ground or can be rotatably set in the support of corresponding grinding rack around its longitudinal axis, thereby by grinding rack being lifted from the rail surface and keeping beam around the rotation of its longitudinal axis and will structure be set with the grinding tool of grinding tool of wearing and tearing and produce from job position, replace this grinding tool arrange structure, with the grinding tool of new grinding tool arrange structure can proceed to this job position and and can descend to the surface of rail, thereby can continue to implement grinding.Particularly because will absorb high reaction force during grinding and bearing the strong vibration occurred in grinding, so this additional rotary freedom requires to keep beam to be locked at more reliably in shared position of rotation.For this reason in the prior art existed, introduction hole or recess in the lock position that keeps Liang Zhong to clearly define, corresponding lock pin inserts these holes or recess when keeping beam to reach terminal location, and in described terminal location, grinding tool is in the use state.By this locking device, can will keep beam to remain on reliably in its position.

But its shortcoming is herein: for special grinding tool, structure is set and can only occupies the definite position of rotation of described maintenance beam in job position in this known equipment and scheme.This has determined that during grinding described grinding tool arranges structure and is adjusted to the relative rail that needs processing all the time in identical location.And in fact not only rail has different shapes sometimes, particularly on extending, rail there is dissimilar wearing and tearing and damage.The damage that need to eliminate by grinding like this and wear phenomenon for example may be distributed on the upside of rail head more according to the situation of rail respectively, on rail cover or offset to the side seamed edge of rail, typically be the rail seamed edge.Needn't remove excessive rail material in order to remove best such wear phenomenon, expectation, can change grinding tool and structure is set at the lip-deep adjustment of rail angle (Anstellwinkel) simultaneously.This is to be difficult to realize with existing system and grinding rack, grinding rack needs integrated moving for this reason, particularly upset, wherein, fitly guide grinding tool in order then to realize along the circular arc of rail head surface, through the cross section of rail, the point of rotation of interior such flip-flop movement should be positioned at rail ideally.Because machine partly need be arranged on top or the side of rail, so yes in such position of the structural point of rotation, can't realize.Therefore, if keep the position of rotation of beam and the rotation tracking of grinding tool orientation also not to mate, grinding rack is used for changing the undesirable adjustment that always causes grinding tool that the revolution of the active position of grinding tool on rail can realize so.

The utility model content

The purpose of this utility model at this is, the grinding rack that should address type to civilian head by the utility model is further developed as follows,, during grinding, position accurately completes the adjusting to the lip-deep adjustment of rail angle to grinding tool, reliably and regularly maintains selected like this position simultaneously.

According to the utility model, described purpose is achieved by being used for that the grinding rack that the equipment of grinding uses is carried out in the surface that is laid on the rail in track, and this grinding rack comprises support; Maintenance beam rotatable around longitudinal axis in this support, that extend along this longitudinal axis lengthwise; In at least two different peripheral positions that are positioned at described maintenance beam, parallel with described longitudinal axis that vertically arrange one by one and be fixed on the grinding tool group that the grinding tool on described maintenance beam forms by a plurality of edges respectively; Be used for making described maintenance beam around the longitudinal axis of this maintenance beam and the drive unit of relatively described support rotation and the fastening devices that is used for fixing the position of rotation of the relatively described support of described maintenance beam, it is characterized in that: described fastening devices have aspect the possible rotation around described longitudinal axis, can not be arranged on with relatively rotating on described maintenance beam, with the cylinder section of internal tooth; Can not be arranged on stop brake shoe on described support, that can press with acting surface described internal tooth, there is the external tooth corresponding with described internal tooth on this acting surface aspect possible rotation around described longitudinal axis with at least one with relatively rotating; And be used for described stop brake shoe is pressed to the actuator of the internal tooth of described cylinder section with its acting surface.

In addition, another solution of described purpose is that it comprises vehicle frame for the surface that is laid on the rail in track being carried out the equipment of grinding during crossing; The wheel travelled on the rail be used in laying in orbit; Be arranged on the grinding rack of the present utility model on described vehicle frame with at least one.

What be used for the surface that is laid on the rail in track is carried out to the equipment of grinding uses is configured with support according to grinding rack of the present utility model.Be extended with along the maintenance beam of (langgestreckt) of longitudinal axis lengthwise the relatively described support of this maintenance beam and be rotatable around described longitudinal axis in this support.Be provided with at least two grinding tool groups in the different peripheral positions that are positioned at this maintenance beam on keeping beam, each freely a plurality of grinding tools of these grinding tool groups form, and these grinding tools are along being parallel to vertically being arranged on one by one in corresponding grinding tool group and being fixed on described maintenance beam of longitudinal axis.In addition, described grinding rack also has for making to keep beam around the drive unit of its longitudinal axis and support rotation relatively and having the fastening devices that is used for fixing the position of rotation that keeps the relative support of beam.

According in mode of the present utility model, here just illustrated, in above-mentioned characteristic aspect, the grinding rack consistent with grinding rack well known in the prior art and the difference of the prior art are: fastening devices has cylinder section (Trommelabschnitt), and this cylinder section is arranged on and keeps on beam and be provided with internal tooth can not be relatively rotated ground (drehfest) aspect the possible rotation around longitudinal axis.In addition, in the novel part according to relative prior art in grinding rack of the present utility model, be: this grinding rack has at least one can not be arranged on the stop brake shoe on support aspect the possible rotation around longitudinal axis with relatively rotating, and this stop brake shoe can press the internal tooth of cylinder section and have the external tooth corresponding with described internal tooth on described acting surface with acting surface.Finally, in scope of the present utility model, be provided with actuator in grinding rack, this actuator can press the stop brake shoe internal tooth of cylinder section with its acting surface.

By this of the fastening devices in the grinding rack of novel structure, according to project organization of the present utility model, can will keep beam be fixed on about in the diverse position of rotation of its longitudinal axis and realize thus the beneficial effects of the utility model: to the grinding tool of grinding tool group in the lip-deep adjustment position of the rail of need processing or adjust angle and carry out fine adjustment, this particularly for grinding tool, be used for grinding rail surface other section location and when grinding rack is moved, in the orientation of the adjustment on rail by keeping beam to follow the tracks of in being torqued into best position.According to fineness and the division of the external tooth of internal tooth and the acting surface stop brake shoe of corresponding tooth, cylinder section, at this, can regulate and the very meticulous angle step (Winkelinkrement) of regulation in advance.Therefore fastening devices is brought into play drum brake is the same as is known effect but conclusive difference is simultaneously: in typical drum brake, the inwall of brake drum is smooth, and this is like this too in the acting surface of brake block.Drum brake is converted simply and is used as fastening devices in grinding rack and can not obtains and will keep beam to be locked at reliably the result of pursuing in the position of rotation selected about its longitudinal axis.Because especially in the described equipment according to EP0708205A1, act on keep on beam, force this maintenances beam around the reaction force of its longitudinal axis rotation or moment of torsion is so large and the vibration that occurs when the grinding is so strong, make the described maintenance beam can not be by simple drum brake maintenance or only at drum brake, be designed and be configured in the situation that the size that can not realize in limited available structure space just can keep.

Preferably use not exclusive stop brake shoe in reality, but use at least two stop brake shoes, these stop brake shoes are diametrically contraposition and the acting surface with external tooth separately presses the medial surface that is provided with internal tooth of cylinder section with them in the opposite direction each other.

It in reality, is often advantageously: the geometry of considering in such a way internal tooth and the external tooth of element, the cylinder section and stop brake shoe fastening devices when the position of rotation to keeping beam is regulated,, keep beam to enter all the time such position of rotation, in these position of rotation these teeth of addressing can be engaged with each other and for example the crown of external tooth with the crown of internal tooth, do not touch and connect.This has prevented such position on the one hand, in these positions to the locking of the position of rotation that keeps beam and fixing unreliable completing.Prevented so on the other hand the possible damage to tooth, this damage otherwise in can connecing in so not carefully and neatly done touching and in the situation that be close to for the stop brake shoe, high thrust occur.In order to realize so accurate location and angular adjustment, for making, keep beam can advantageously comprise stepping motor or servomotor around the drive unit of its longitudinal axis and support rotation relatively, and in order to grasp the relative position kept between beam and support, corresponding position sensor can be set in addition.

As illustrated at literary composition head, according to grinding rack of the present utility model, advantageously be applied in according in the scope of the described method of EP0708205A1 or equipment and just according to these methods operations.On this point, grinding rack is advantageously constructed as follows,, grinding tool in the grinding tool group is respectively around a rotational symmetric peripheral grinding tool of grinding tool rotation, these peripheral grinding tools can so be bearing in with rotating freely and are fixed in the fixed mount kept on beam and are fixed on described maintenance beam around the grinding tool rotation, that is, described grinding tool rotation is orientated the orientation angle that becomes to be not equal to right angle with the longitudinal axis that keeps beam.So these grinding tools can move with the methods described in EP0708205A1.The disclosure of consulting described document for the structure of necessity of the enforcement of the mode of further setting forth and narrate this operation or this method and this equipment.On this point, the disclosure of EP0708205A1 is in this also is incorporated into disclosure of the present utility model fully.

The size of orientation angle in project organization as above advantageously between 30 ° and 60 °, particularly 45 °.

Because structurally very narrow for the structure space according to grinding rack of the present utility model, purpose is that this grinding rack is designed compactly as far as possible and has small size, so the cylinder section can be advantageously disposed on the inside that keeps beam and about the longitudinal axis symmetry of this maintenance beam.Keep beam can have the corresponding shrinkage pool of coming from the end face guiding, this shrinkage pool is configured to blind hole for this reason.As alternative, and this is preferred in scope of the present utility model, and the cylinder section can be also generally along the section in the hole of vertically crossing this maintenance beam that keeps beam.Such hole is not only for the cylinder section is set, and it in addition can be for boot media circuit, electric line and similar member, thereby such circuit no longer needs other structure space, and it is compact that structure can keep.

Although still can interrupt with only short debugging in order to produce the height wearing and tearing of having addressed as first as literary composition on grinding tool, long-time as far as possible and over long distances carries out grinding to track section, advantageously keep on beam having four respectively about longitudinal axis, along the grinding tool groups of the 90 ° of angles ground settings of periphery dislocation that keep beam.Before all grinding tool groups been have have been worn and torn and must have been changed in longer debugging dwell time (Ruesthalt), this allows four replacing grinding tool groups.

In scope of the present utility model, also a kind of equipment that grinding is carried out in the surface of the rail in being laid on track during being used for crossing is illustrated, this equipment has vehicle frame; Be fixed on described vehicle frame, for being laid on the wheel travelled on the rail of track; Be arranged on grinding rack on described vehicle frame, as described in the foregoing description with at least one.This equipment also advantageously has the mobile device for grinding rack is moved relative to vehicle frame.This mobile device particularly vertically works and also allows at the same time surface extruding or the compression towards the need processing of rail by the grinding tool of grinding tool group.But mobile device also can be advantageously used in the grinding rack along continuous straight runs is relatively moved, so that the degree of freedom of the vertical movement of the degree of freedom moved horizontally that like this can enough grinding racks, grinding rack and the degree of freedom that may adjust that keeps the position of rotation of beam in the support of grinding rack are carried out best orientation to abutting in the lip-deep and grinding tool that press these rail surfaces of the rail that needs processing.

Fig. 2 illustrates the schematic diagram of grinding unit 4 with the diagram of greatly simplifying, this grinding unit has rail wheel 5 on vehicle frame, by the described grinding unit of these rail wheels, on the rail S of grinding, travels needing.Such grinding unit 4-is the ingredient of complete grinding car also-typically in the prior art, and that described grinding car has usually is a plurality of, for example four such grinding units are laid on the rail S of track abreast for two of grindings.Be provided with grinding rack on grinding unit 4, there is the beam 6 of maintenance in the support that this grinding rack is not shown specifically herein.Can vertically from rail S, lift or drop on this rail and to the rail surface with the grinding rack that keeps beam 6 and compress.The position of finally addressing shown in Figure 2.In order to make vertically to move with the grinding rack that keeps beam 6, be provided with lifting and pressure cylinder 7, these liftings and pressure cylinder not only make to rise and descend with the grinding rack that keeps beam 6, but also apply towards the thrust of the direction on rail S surface on maintenance beam 6.Keep beam 6 to comprise the grinding tool be arranged in grinding tool group 8, as can seeing in this accompanying drawing, these grinding tools are arranged to the acute angle that is oriented with rail S with different orientations.A grinding tool group 8 only is shown in this schematic diagram, yet wherein, keeps beam 6 to comprise a plurality of such grinding tool group 8 be arranged on different peripheral positions.

This can be more clearly visible in Fig. 3, in the figure for structure is described rail S top only is shown maintenance beam 6 together with the grinding tool group 8 be arranged on this maintenance beam.Can also see the longitudinal axis 9 that keeps beam 6, described maintenance beam can be around this longitudinal axis rotation.Can know that also have integrating of seeing is arranged on each grinding tool 1 in grinding tool group 8 here, these grinding tools separately around their grinding tool rotation can accept respectively with rotating freely with remain on each grinding tool fixed mount 10 in and by this grinding tool fixed mount 10, with maintenance beam 6, be connected.Can also see, in this project organization, in each grinding tool group 8, altogether be integrated with 12 with longitudinal axis 9 parallel orientation ground, the grinding tool 1 in being arranged on a line one by one.Wherein each three outermost grinding tools 1 by with its grinding tool rotation with the longitudinal axis 9 that keeps beam and therefore also arrange with acutangulate the first orientation of rail bearing of trend, a group of forming of the grinding tool in the middle of being positioned at by six be arranged to reverse mode with vertical 9 acutangulate, about the plane of the longitudinal axis 9 perpendicular to maintenance beam mirror image orientation symmetrically accurately.This different directed be used on the one hand reducing produce, around vertical axis act on keep the moment of torsion on beam 6 and also be used on the other hand being reduced in grinding in service, by act on the active force kept on beam 6 in a horizontal plane transverse to longitudinal axis 9.In order to simplify diagram, 8, one grinding tool groups of two grinding tool groups only are shown in Fig. 3 in the position on the rail surface towards rail S, second grinding tool group is in reversing approximately the position of 180 ° around grinding tool longitudinal axis 9.Yet as can seeing in Fig. 4, in fact keeping, on beam 6, four such grinding tool groups to be arranged, these grinding tool groups are the other grinding tool group be arranged in the centre position of 90 ° of misplacing respectively.That is to say, keep beam to there is criss-cross cross section basically, each grinding tool group 8 with the end that is arranged on rood beam of these cross sections, this grinding tool group consists of the grinding tools 1 that grinding tool rotation separately can be fixed in grinding tool fixed mount 10 with rotating freely around it, and described grinding tool fixed mount is fixed on the end of described rood beam.

Illustrate on the one hand and keep beam 6 around the freedom of motion of its longitudinal axis rotation and the freedom of motion that vertically rises and descend is shown on the other hand by rotation arrow RP and double-head arrow D.For support (further not illustrating in this accompanying drawing) relatively being fixed in the position of rotation of the relative support through overregulating by the maintenance beam 6 along the direction rotation of rotation arrow RP (in principle also can along the direction that is in reverse to the direction of arrow and extends), be provided with fastening devices, hereinafter also with reference to Figure 10 its illustration a) and b) in further being set forth according to project organization of the present utility model this fastening devices.

Fig. 5 is illustrated in meaning and the fundamental property of the freedom of motion schematically shown in Fig. 4 at first again, and described freedom of motion for implementing the grinding tool with new grinding tool quick-replaceable wearing and tearing during rail is carried out to lasting grinding.Shown in Fig. 5 a: be arranged in grinding tool 1 wherein, that wear and tear due to lasting grinding therebetween ' grinding tool group 8 ' how to be placed at Working position on the surface of rail S.Keep beam 6 also to have three other grinding tool groups 8, these grinding tool groups are arranged on the end of cruciform girder of cross-like cross-section along the periphery of this maintenance beam 90 ° of ground that misplace respectively.Herein for use grinding tool with new grinding tool 1 arrange structure 8 change grinding tool with the grinding tool 1 ' of wearing and tearing arrange structure 8 ', as shown in Fig. 5 a, at first will keep beam 6(in fact together with support) vertically from rail S, lift, as gone out illustrated in the arrow by shown in the right side of this figure.In next step, keep beam 6 herein in support not shown further and relatively this support along 90 ° of the anglecs of rotation of direction rotation of the arrow in the counterclockwise sensing shown in the accompanying drawing upper right side, thereby make grinding tool 1 with wearing and tearing ' grinding tool group 8 ' produce from job position and also shown in the accompanying drawing left side adjacent, proceed to this job position with the grinding tool group 8 of new grinding tool 1.What at this, rotatablely move is last, keeps beam 6 again to descend together with support not shown further herein, until at the new grinding tool 1 in adjacent grinding tool group 8 as be placed in the lip-deep job position of rail S can seeing in Fig. 5 c.This decline illustrates by the arrow plot shown in the figure upper left side in Fig. 5 c.After replacing such, that can automatically implement during grinding with controlling, can proceed grinding, until shown in Fig. 5 c, now be placed in rail S lip-deep, with grinding tool group 8 wearing and tearing of still new grinding tool 1.If this is the case, so again repeat process shown in Figure 5 and in the end again implement, until all four be arranged on the grinding tool group 8 that keeps on beam 6 or 8 ' with old, be arranged on

grinding tool

1 or 1 in these grinding tool groups ' wearing and tearing.Then just interrupt grinding operation and need to stop in case with new grinding tool 1 change the grinding tool 1 that weares and teares '.Shown at Fig. 5 b, make to keep the step of beam 6 support rotation not shown further relatively herein after, in grinding, at grinding rack with after being arranged on the maintenance beam decline on this grinding rack, can be directed into before the position shown in Fig. 5 c, this maintenance beam 6 support is relatively fixed and is locked, and this is achieved in the mode of also further setting forth with reference to Figure 10 hereinafter by fastening devices.

At first illustrate in accompanying drawing a and b in Fig. 6, how can the zones of different of this rail surface SO be carried out to grinding and processing by difference location and the adjustment of the lip-deep grinding tool group 8 of the rail to acting on rail S.During the position shown in Fig. 6 a, to the seamed edge zone of rail surface SO, typically the so-called seamed edge that travels carries out grinding, and in the position shown in Fig. 6 b to superposed rail surface, typically so-called tread carries out grinding.Diagram to Fig. 6 a and 6b carries out simply relatively just finding out, for this change of grinding position, keeps beam 6 to rotate around its longitudinal axis 9.If this rotation can not be moulded by the corresponding sports of support fully, this normally impossible (referring to hereinafter) for this reason, at least one component of motion must obtain by the rotation that keeps beam 6 relative supports, wherein, this rotation only forms the sub-fraction of the angle in order to change the required rotation of the grinding tool group 8 of initiatively being drawn in grinding, makes in the centre position that keeps beam 6 must be able to be adjusted to relative support and also must be able to be locked there.

Fig. 6 c in the motion flow chart, again illustrate the surface segment that needs grinding on the rail surface SO in order to change rail S position and to the adjusting of the maintenance beam 6 of the grinding tool group 8 with disposed thereon.

Form with the local diagram of the accompanying drawing of Fig. 6 c in Fig. 7 illustrates the synthetic motion that will realize ideally.In order to follow ideally the surface profile of rail surface SO when changing according to position shown in Fig. 6 a and 6b, need a kind of motion of design, this motion is equivalent to keep beam 6 around a rotation that is positioned at the point of rotation DP under the peak of rail surface SO of rail S inside with distance A.Structurally be anchored the point of rotation there because certainly can not mechanically construct, so must simulate corresponding motion by the stack of different motion component.As can seeing in Fig. 8 and 9, in any case such stack also needs to keep the component motion of the tracking rotary of beam 6 relative supports except structural being articulated and connected of the support that adopts grinding rack and the vehicle frame of for example equipment for grinding.

In the scheme schematically shown at Fig. 8, on grinding rack 12 comprises support 11 and is arranged on this support 11, around the coilable maintenance beam 6 of relative this support of its longitudinal axis 9, this grinding rack is fixed on vehicle frame F G by the cantilever construction with elbow joint bar K.Stretching routine or bending motion by elbow joint bar K make grinding rack 12 upsets, and wherein herein, support 11 is fixed on a maintenance beam 6 in position of rotation with relative this support and jointly overturns.At this, the point of rotation DP not around going out as shown in FIG. 7, in the inside of rail S carries out in such upset.Or rather, it carries out around pin joint G, at this pin joint upper bracket 11, with the lever arm H of bottom, be connected, this lever arm relative vehicle frame F G in this motion keeps relative stiffness and stiff (lever arm H lifts with also being hinged in principle on vehicle frame F G, is used for making grinding rack 12 lift or descend).As can seeing in Fig. 8 b, the adjusting to grinding rack 12 of so independent exercise by elbow joint bar K causes the grinding tool 1 of grinding tool group 8 to lift from the surface of rail S.Even the grinding tool 1 of grinding tool group 8 in such motion-because the effective range of this motion very short-from the surface of rail S, do not lift, these grinding tools also leave the lip-deep desired position of rail, thereby can not keep this desired grinding position.For the grinding tool 1 that obtains this position and make grinding tool that structure 8 is set again in correct position with the Surface Contact of rail S, need another component motion, that is, the rotation of the maintenance beam 6 relative supports 11 of having addressed.This is rotated in Fig. 8 c and illustrates by an anticlockwise rotation arrow drawn in the zone of rail S.Certainly keep beam 6 relative support 11 fixing and lockings again when such rotatablely moving finishes, be provided with the fastening devices designed according to the utility model, also will further illustrate hereinafter for this reason.

Schematically show the alternate ways of the position adjustments that keeps beam 6 and the grinding tool group 8 be connected with this maintenance beam in Fig. 9, wherein, support only carries out linear movement and is not overturn or gyration, wherein, also needs to keep the correction motion of the relative rotation form of the relative support of beam here.In the scheme schematically shown at this, for the vertically vertical guiding device V along continuous straight runs of movement of guiding of support 11, be placed in movingly vehicle frame F G in Fig. 9.By the movement of this level, at first support 11 and coupled maintenance beam 6 can vertically move, and make the grinding tool 1 of the lip-deep grinding tool group 8 that acts on rail S can vertically carry out the lip-deep location at rail S with guiding.Certainly can't be mated grinding position thus, this coupling also needs vertical component motion.This component motion obtains by vertical guiding device V, this vertical guiding device can be realized the support 11 and vertical motion of grinding rack thus.As shown as Fig. 9 b, here now for the grinding tool 1 of accurately regulating grinding tool group 8 in the lip-deep location of rail S, also need to keep the relative support 11 of beam 6 to be rotated around the longitudinal axis 9 of this maintenance beam 6.Also need to arrange such rotation here, this rotation forms the sub-fraction of the anglec of rotation, as it in order to change grinding tool group 8 set like that (with reference to the Fig. 5 that is used for this replacing).In addition, for the grinding tool 1 by grinding tool group 8 accurately is positioned on the surface of the rail S arranged for grinding, the possibility that need to be regulated in little angle section (Winkelabschnitt) the relative position kept between beam 6 and support 11, wherein, in the angle of corresponding adjusting, need to arrange by the fixedly maintenance of fastening devices.

Arrange for this reason according to fastening devices of the present utility model shown in Figure 10 a and 10b, in Figure 10 a, be in a fixed position, in Figure 10 b in off-position.Can be clear that the cylinder section 13 kept on beam 6 that is arranged on here, this cylinder section has internal tooth 14.Described cylinder section 13 is symmetrically directed around the longitudinal axis 9 that keeps beam 6.Cylinder section 13 is surrounded by axle sleeve 15, and this axle sleeve is the fixing ingredient at its more details support not shown further.In axle sleeve 15, with longitudinal axis 9 rotations that the cylinder section 13 that keeps beam 6 to be fixedly connected with can keep beam 6 around this, this cylinder section can be rotated to support in this axle sleeve.Two stop brake shoes 16 are fixed on axle sleeve 15 and thus and are fixedly connected with support, and these stop brake shoes have external tooth 17(with the corresponding structure of internal tooth 14 of cylinder section 13 referring to Figure 10 b on their acting surface).Stop brake shoe 16 is connected with actuator 18, by this actuator, these stop brake shoes can move relative to one another and separate with internal tooth 14 on being configured in this medial surface with external tooth 17 and the medial surface of cylinder section 13 on being configured in these acting surfaces with their acting surface or can be extruded and be separated from each other and can be with their external tooth 17 and the internal tooth 14 locking ground engagements of cylinder section 13.At this locking state shown in Figure 10 a, shown in Figure 10 b, it is being the position that fastening devices is separated, the acting surface of stop brake shoe 16 is removed the engagement with the internal tooth 14 of cylinder section 13 with their external tooth 17, thereby keep beam 6 in this position, support and the axle sleeve 15 that is molded on this support rotate relatively.

From the diagram of Figure 10, can easily draw: use according to of the present utility model, by mating reaction on their acting surface, fastening devices that form with the cylinder section 13 of internal tooth 14 and stop brake shoe 16 with external tooth 17, keep beam 6 with the maintenance reliably by force closure and the sealed combination of shape of between the support of axle sleeve 15, relative position that arrive.Can see in addition: respectively according to the size of the tooth of the structure of tooth and external tooth 17 internal tooth 14 and corresponding with it, keep beam 6 only can be in the Difference angles of very little increment locking.This specific character of project organization by fastening devices, can differ widely with in the angle that can finely tune, the position of rotation of the maintenance beam relative support required according to afore-mentioned is fixed and this is undertaken by a kind of mode, although make the very large reaction force occurred in grinding also can keep reliably the relative position of these maintenance beam 6 relative supports with vibration.
