Description
Technical field
The utility model relates to a kind of device of laying guide rail surface in orbit for attrition process during crossing.
Background technology
Laying guide rail is in orbit because constantly crossing of train fast running and/or heavy load is subject to obvious wearing and tearing.This wearing and tearing first often show with the formation of cut or groove and the formation of microfissure.If this wearing and tearing are not eliminated by periodic maintenance, so this wearing and tearing can develop into the substance of guide rail and damage, and be a kind of serious threat to the safety of further railway traffic transport like this, until cause the dangerous of guide rail fracture and cause thus derailing.
In order to prevent this danger and to eliminate wearing and tearing or repair and the frayed guide rail of moulding again, be that surface to guide rail, particularly drive a vehicle face and driving seamed edge are implemented attrition process as feasible method at present.Such attrition process is especially for modern high-speed railway, for example, as the high speed rail system (TGV) of German ICE train (ICE), France or the Shinkansen of Japan.Because such attrition process is implemented on the guide rail of laying in orbit, for this reclamation activities self-evident guide rail can not be taken out and is fixed from track fixedly in grinding stations, grind, so typically use so-called grinding train for this reason.This grinding train---conventionally remains on and grinds in frame---has the abrasive body unit with multiple abrasive bodies, and these abrasive bodies drop in guide rail surface and by these guide rail surface guided-movings.
This device or this grinding train are introduced to some extent in EP 0 708 205 A1.At this, each abrasive body is symmetrically configured to side face abrasive body and rotates freely around abrasive body rotation, and this rotation is not by motor or similarly drive unit driving.Utilization drops to side face abrasive body in guide rail surface and that press to this guide rail surface, grinding train travels forward now, now side face abrasive body longitudinally acutangulates with its rotation and guide rail, is actuated to the frayed surface that is rotated and meanwhile brings into play abrasive action and correspondingly remove guide rail like this by relative motion.Can move continuously with higher speed according to the grinding train of this technical work; Here speed can reach about 80km/h.
This high cross with operating rate under, the grinding particle producing in the time of attrition process is not only heated to high temperature and splashes continuously as red-hot spark, they stand heavy impulse and kinetic energy in addition, thereby they at full speed move from grinding part continuously with high-energy.In order to prevent that grinding particle that these parts are red-hot and spark from entering other surrounding environment of the track that utilizes attrition process processing (there in the worst case can initiation fire or cause other to damage), but also bring hostile environment impact in order to prevent because of entering of corresponding grinding particle, in this device, in the side of abrasive body unit, baffle plate is set, block that grinding particle and spark splash and by the region of corresponding particle and spark interception the abrasive body unit in the region of device and there, especially for siphoning away grinding particle and prevent from being thus discharged in environment from this space.This baffle plate is particularly owing to originally can must being very straitly positioned on abrasive body unit for the narrow space of domination in track, but this baffle plate requires maximum size.In this regard, this requirement not only comes from the grinding particle that hits baffle plate with kinetic energy and heavy impulse, and particularly comes from and most of hit as red-hot spark the high temperature that the particle on described baffle plate has.Also make the baffle plate being typically made of metal bear high heat load (attempt making corresponding construction by plastics or natural elastomer, but encounter difficulties again and again, therefore these materials can not reliably sustain) so here aspect high heat load.
The heat requirement of baffle plate make baffle plate itself be heated to always they start heating temperature.These high heat loads not only make fatigue of materials, but also cause the warpage of planar plate and the application life that therefore distortion also also causes obviously shortening these parts.In addition, the heat requirement of baffle plate is also transmitted in the miscellaneous part of access to plant as temperature, and these miscellaneous parts should not resist with the temperature of corresponding raising equally, face the danger of scrapping under this heat requirement.Here the trial that utilizes water or other liquid medium refrigerated baffles to carry out is unsuccessful.Because on the one hand corresponding liquid must be carried on device with enough amounts, this causes space problem and the additional liquid amount of whether carrying causes higher energy consumption.On the other hand, adopt liquid for example to carry out coolingly causing mixing of grinding particle and spark and liquid as water, thus the mixture of generation mud shape, and it can pollute track and can not reliably be intercepted and captured and dispose from environment.Utilize gaseous fluid to wash away baffle plate and also do not bring forth good fruit under high travel speed to play thus the trial of cooling effect.In order to provide enough other trials cooling and that use the simple cooling fin of adequate thickness to carry out to pack into without any problems in baffle plate here, this is because spark and grinding particle can be discharged by such cooling fin, no longer can reliably be tackled simultaneously.

As device well known in the prior art, first there is the walking mechanism with tire for travelling along the guide rail of laying in orbit according to device of the present utility model.This device has in addition at least one and grinds frame, the side face abrasive body that the fixing tandem extending longitudinally with at least one sets gradually in this grinding frame.These side face abrasive bodies are merged into an abrasive body unit being made up of the tandem of side face abrasive body.Each side face abrasive body has respectively one can be by being put into the circumferential surface in laying guide rail surface in orbit.The each side face abrasive body arranging in abrasive body unit is separately around abrasive body rotation Rotational Symmetry.In this regard, each side face abrasive body around abrasive body rotation can free rotary ground supporting grinding in frame and be arranged in the abrasive body unit extending along tandem.The abrasive body rotation of each side face abrasive body is separately to be different from the longitudinal setting of the directional angle at right angle with respect to abrasive body unit.Thus, this device is equivalent to substantially as disclosed that device in EP 0 708 205 A1.
In foundation device of the present utility model, each side face abrasive body arranges group by group with the form that is merged into respectively adjacent side face abrasive body abrasive body group, that set gradually in abrasive body unit, and these side face abrasive bodies have substantially parallel, the complete abrasive body rotation of parallel orientation particularly each other in abrasive body group inside.In abrasive body unit, be provided with at least two group side face abrasive bodies, described at least two group side face abrasive bodies longitudinally set gradually, and in described at least two group side face abrasive bodies the corresponding abrasive body rotation of each group of side face abrasive body of longitudinally adjacent setting with different angles the portrait orientation with respect to abrasive body unit.Particularly, the different abrasive body rotations that arrange can along the plane Mirror Symmetry perpendicular to longitudinal distribute.In use observe, first group of side face abrasive body about the guide rail of processed guide rail longitudinally and in the time observing rail head from above with its abrasive body rotation respectively clockwise with acute angle with respect to guide rail bearing of trend (guide rail is longitudinal) rotation, second group of side face abrasive body with its abrasive body rotation with acute angle that particularly numerical value is identical counterclockwise with respect to this direction rotation.
In this regard, particularly grouping and these groups arrange side face abrasive body so thus,, make thus synthetic total power of being formed by the reaction force of side face abrasive body and and act on abrasive body unit or grind the same being minimized of synthetic torque in frame during grinding, optimum elimination to zero.Thus, structure is set can follows disclosed instruction in EP 2390415 A1 and form of side face abrasive body.
Side face abrasive body has the abrasive body longitudinal axis extending perpendicular to abrasive body rotation, pass corresponding side face abrasive body, and these abrasive body longitudinal axis provide the direction that this abrasive body may roll on orbit plane.Be in operation if had transverse to the side face abrasive body of the abrasive body rotation of portrait orientation and---namely in the time that device advances on guide rail---press to guide rail surface, their rotation roll extrusion with respect to guide rail direction rotation orientation around it so, wherein, they carry out relative motion and implement thus grinding with respect to guide rail surface.The grinding thing (namely spark and grinding particle) producing in the time that grinding is travelled and grind along the direction of abrasive body rotation and against the circumference of travel direction and side face abrasive body tangent throw away.For stoping these sparks and particle to splash, particle is tackled in the region of abrasive body unit, to for example can utilize there aspirator to catch, be provided with baffle plate in the both sides of abrasive body unit, it is for tackling at the grinding granule that grinds generation in service.By the side face abrasive body with respect to fore-and-aft tilt orientation with its abrasive body rotation is set group by group, on each baffle plate, form the first and second sections, abrasive body longitudinal axis first section crossing with the surface of corresponding baffle plate and abrasive body longitudinal axis are through the second section of baffle plate.In other words, in the first section, abrasive body longitudinal axis or its extension are crossing with plane or the surface of corresponding baffle plate, and in the second section, the plane of corresponding baffle plate or surface are not crossing with abrasive body longitudinal axis.According to the utility model, in the second section of baffle plate, be provided with the ventilation opening transverse to the longitudinal extension of abrasive body unit, these ventilation openings have the air guide structure of the plane extension of the corresponding baffle plate from place is set himself.Thus, the beneficial effects of the utility model are: the grinding particle that the spark that interception produces reliably on the one hand splashes and produces in the time of attrition process, meanwhile also provide but then improved cooling possibility, to prevent in such a way the hyperthermia load of these parts.
Therefore the fact shows, the directionality that the grinding particle producing in the time of attrition process and spark leave is very strong, the rear end of definitely observing in the travel direction along device of corresponding side face abrasive body is along the direction perpendicular to its abrasive body rotation, namely along the direction of its abrasive body axis as above, and along the direction tangent with the circumference of side face abrasive body.This situation is here fully used, and its mode is: in abrasive body unit, side face abrasive body is merged into multiple groups in mode as above.On the surface of baffle plate, form thus the first and second sections.Because the spark leaving and grinding particle are substantially along the orientation of the abrasive body longitudinal line of movement track that splashes, the first section of baffle plate is hit by spark and particle, and in the second section, does not observe or only observe considerably less spark and particle splashes.This point is applicable to the attrition process of the travel direction possible along two of device (forward/rewind), because the particle loaded of not splashed and flying out by spark in the situation of the travel direction that the second section meaning in office is selected, reason is that this section is not crossing with abrasive body longitudinal axis, thus outside particle and spark splash direction.In the second section, in the region namely " being blocked " in corresponding baffle plate what is called, the utility model people recognize, the corresponding ventilation opening (ventilation gaps) with air guide structure can be set now, these ventilation openings in the time that this device travels, outside air is guided through air through-flow mouthful and therefore import defibrator process cut particle and spark hit baffle plate in the cooling region of wanting.In this regard, air is through-flow, and mouth can adopt larger width without any problems, and for example---and preferably---width with 10mm to 50mm forms.Air guide structure can be especially simply by the plate section bending producing when the punching press ventilation opening is formed.Tool is advantageous, and ventilation opening and air guide structure thereof form so in this regard in this section, that is, the Part I of through-flow mouthful of air is had at device and advance and pass air into the air guide structure in wanted cooling region while travelling; The Part II that air is through-flow mouthful has along the travel direction of respective opposite, falls back while travelling and air to be imported and to be passed through-flow mouthful of these air and enter the air guide structure in wanted cooling region along the direction of through-flow mouthful of air at this device.In this regard, through-flow mouthful of design air like this,, in corresponding travel direction " leading ", the through-flow mouth of air of namely observing before abrasive body unit along travel direction has for air being imported to the air guide structure in the region after it under the travel direction of corresponding selection.Thus, leaked-in air can be observed the region after it along travel direction for the best is cooling.Namely, preferably, in the second section, be provided with and when being included in this device and advancing, air imported to the ventilation opening of the air guide structure in ventilation opening and is included in this device the ventilation opening that while falling back, air is imported to the air guide structure in ventilation opening.Further preferably, described air guide structure is by forming the plate section bending producing when the punching press ventilation opening.Also preferably, the gap width of described ventilation opening is 10mm to 50mm.
The utility model people recognize in addition, also can be in the first section, and namely grinding particle and spark hit corresponding baffle plate or depend in the region that the travel direction of device at least can hit and be provided with and meet the ventilation opening of determining condition.Therefore, utilization the utility model proposes, and in the first section of baffle plate, is provided with other ventilation opening, and they adopt the form in vertical gap, and gap width is maximum 5mm, and preferably 2 to 3mm, and air guide structure is not set thereon.Namely, preferably, other ventilation opening is set in the first section on each baffle plate, described other ventilation opening is that gap width is 5mm to the maximum and there is no the form in the vertical gap of air guide structure.Therefore the fact shows, in the time that these vertical gaps have quite little gap width and there is no air guide structure, even in the first section, namely standing in region that spark and grinding particle flow into, these particles can not be through corresponding vertically gap in baffle plate.This point is that foregoing grain flow hits baffle plate along the direction orientation of abrasive body longitudinal axis.Because described abrasive body longitudinal axis tilts to extend with respect to the plane of baffle plate, this plate is typically along the longitudinal extension of abrasive body unit, so particle can not pass narrow vertical gap.Vertically gap here gap width feasible and that can select finally depend on the thickness of baffle plate.In any case gap width also should not exceed the thickness of baffle plate, is particularly chosen as the thickness that is less than baffle plate.
Special tool is advantageous, and gap width is 2 to 3mm (particularly in the situation that Weir Plate Thickness is 2 to 5, preferably 2 to 4mm).Namely, preferably, described other ventilation opening is that gap width is the vertical gap of 2mm to 3mm.Further preferably, the spacing between adjacent vertical gap at 40mm between 60mm.
The baffle plate that is arranged on side, abrasive body unit particularly can be obliquely installed trough shape, has in lower area narrow openings and is tilted to the profile of outer orientation, the distance of namely upwards widening.These baffle plates are in operation the grinding thing splashing and spark are upwards guided and be advantageously provided with pump orifice there from rail head thus.
Can tool advantageous according to the baffle plate of device of the present utility model, particularly on its height, arrange movably independently of each other, wherein, this movement of baffle plate can be irrelevant with the vertical position adjustment of abrasive body unit or abrasive body support.Namely, preferably, described baffle plate vertical position at this baffle plate on this device arranges movably, and wherein, baffle plate can move and have nothing to do with the vertical position adjustment of abrasive body unit.Abrasive body unit or abrasive body support also must radially be adjusted continuously along it in the time that side face abrasive body progressively occurs wearing and tearing again, according to wearing and tearing particularly constantly to the direction adjustment of the guide rail that will grind (until the wearing and tearing of side face abrasive body reach need to by the degree of its replacing).The elevating movement of corresponding baffle plate can not be carried out along the vertical line of motion in this regard, carries out, in case baffle plate collides with side face abrasive body under rise state but must be tilted to.But irrelevant therewith, baffle plate must keep location, that is, the region that occurs spark and grinding grain flow in guide rail surface reliably being covered like this, particularly also will reach below it.Baffle plate is downwards, namely undesirable to the further transposition of base portion of track bed in this regard, for example, to prevent that this baffle plate and the object (rubble or such object) in orbital region from colliding.In addition, definite in the situation that, also can require baffle plate independently upwards to promote respectively and with abrasive body unit, for example, the in the situation that of thering is structure on guide rail side install in orbital region, for example, wheel steering gear in track switch or region, intersection or for the supply line of heatable track switch or the attachment of such object.If at this class formation equipment, the attrition process of guide rail should not be interrupted on this position so on the one hand, on the other hand, can require to promote baffle plate at track region memory, to prevent and these structural device collisions.This point provides the movement of baffle plate and abrasive body unit irrelevant mobility.
For particularly in the situation that considering said structure equipment, but also with orbital region in other obstructions that may exist reliably prevent relatively and its collision, and can not depend on people's intervention here, as proposing according to the advantageous improvement project of a kind of tool of the utility model, be provided with monitoring sensor according on device of the present utility model, utilize it to monitor possible obstruction in the orbital region crossing in the region of baffle plate process, and this monitoring sensor is connected with control device, this control device triggers baffle plate is carried out to vertical-lifting in the time recognizing obstruction.After the signal that this control device no longer exists at the obstruction that receives monitoring sensor, then baffle plate is vertically fallen.Namely, preferably, be provided with monitoring sensor, in the time recognizing obstruction, trigger for monitoring the obstruction that may exist in the orbital region crossing in the region of baffle plate process and having the control device that relevant baffle plate is carried out to vertical-lifting.
According in device of the present utility model, finally also can be provided with on the face towards track, be arranged on after baffle plate for aspirating the aspirator of spark and grinding particle.Namely, preferably, between each baffle plate, be provided for aspirating the aspirator of spark and grinding particle.This aspirator can absorb the grinding particle and the spark that occur as contamination particle as far as possible, thus their entered environments being retained in orbital region or above it uncontrolledly not.Corresponding aspirator can be connected with the container carrying on foundation device of the present utility model, collects and deposit corresponding particle in this container.This container can be emptying in the time safeguarding or assemble according to device of the present utility model, and the grinding particle entering can meet environmental protection and process in accordance with regulations.
Being also provided with backstop according in device of the present utility model, baffle plate is kept off in these backstops and limit definitely thus descending motion at the down position of baffle plate.These backstops are used for making corresponding baffle plate accurate directed and fixing with respect to guide rail at down position.Movably the guide device being arranged on unit framework of baffle plate also has certain flexibility as baffle plate itself, and this makes baffle plate accurately become difficulty in location with respect to guide rail in the situation that there is no other additional devices.By baffle plate is being bumped against near guide rail in definite backstop, baffle plate can be obviously accurately with directed rigidly.In this regard, baffle plate utilizes side-strut or bearing surface to be close in backstop or closely forms to this backstop at a certain angle with respect to adjusting direction, thereby produce a kind of keyway effect, and baffle plate " is caught " by this backstop in the time declining and approach respective stopping also finally accurately directed at terminal location.Backstop has advantage ground and is arranged on like this on the framework that grinds unit, that is, it is close to above guide rail.By putting direction and causing that angle between side-strut or the bearing surface of keyway effect is between 45 ° to 90 °.Backstop can circle or rectangle form, corresponding bearing surface is corresponding formation.Conventionally, backstop be on guide rail or bearing surface in baffle plate, to form the guide part with keyway effect be indifferent.But tool is advantageous, key-way shape guide part opens wide downwards, thereby the grinding dust of deposition can be to falling in track.Namely, preferably, be provided with multiple backstop, the descending motion of these backstop defining baffles and the down position at baffle plate recline baffle plate gear in this backstop and with side-strut.
Advantageously, side-strut or bearing surface can have two and form with the linearly extended line of angle that is different from 0 ° or 180 ° each other.Then according to object, limiting structure is to have corresponding contact surface.Realize the guiding to decline baffle plate and hold it under the state of decline about two direction in spaces definitely thus.

This situation also can be with reference to the top view of observing from above, and the horizontal view plane of the abrasive body longitudinal axis 15 namely extending perpendicular to the rotation 2 of side face abrasive body 1 describes.Because grinding particle AP splashes along these abrasive body longitudinal axis 15 orientations, thereby those crossing regions of abrasive body longitudinal axis 15 and baffle plate 11 or its surface can be used as grinding particle AP and hit the region 12 (according to travel direction) that maybe can hit baffle plate 11 in this top view.Abrasive body longitudinal axis 15 not crossing with the surface of baffle plate 11 or extend through those regions or section 13 are second sections 13 that the grinding particle AP irrelevant with selected travel direction F can not hit baffle plate 11.
This situation and this understanding are utilized now, and its mode is: according to the present invention, in baffle plate 11, (as shown in Figure 7) arranges through-flow mouthful 14 of air.Fig. 7 is also the diagrammatic top view of the abrasive body unit according to earlier drawings on guide rail S, and wherein this figure also schematically illustrates baffle plate 11.Can find out, on baffle plate 11 in the second section 13, namely air through-flow mouthfuls 14 is set in not crossing with abrasive body longitudinal axis 15 and corresponding those sections that are not ground particle AP sputter, these air are through-flow, and mouth adopts the form in laterally uncovered vertical gap and has air guide structure, the deflector that this air guide structure is outside form here, namely residing region extrudes from abrasive body unit.That these deflectors have is separately outside, namely towards the front end of abrasive body unit or the opening of rear end, thereby cause as shown in the figure air-flow LS, this air-flow enters inner chamber according to travel direction from baffle plate 11 outsides through through-flow mouthful of 14 (shown in these dotted lines) of air, so that cooling corresponding baffle plate 11 and interior zone.If the device with abrasive body unit travels along travel direction left in Fig. 7, be correspondingly formed on the air-flow LS shown in this figure left side.Thereby do not occur through the air of through-flow mouthful of the other air shown in this figure right side through-flow.Adopt the air shown in arrow and the air-flow LS of this figure right side mark through-flow in opposite direction, namely form when the travel direction of direction to the right in Fig. 7, wherein, do not occur through the air through-flow mouthful 14 of the air shown in this figure left side of two baffle plates 11 through-flow.
Fig. 8 illustrates the view of the baffle plate 11 with the through-flow mouth 14 of air of Fig. 7 again, wherein, and the additional direction of splashing that marks out the travel direction grinding particle AP possible for two here.So again show, air is through-flow mouthfuls 14 not to be hit in the region of baffle plate 11 in grinding particle AP in any travel direction, namely abrasive body longitudinal axis 15 (with reference to Fig. 6) do not intersect with baffle plate 11 or with its surperficial disjoint those regions.
Fig. 9 is being similar to the view of Fig. 8, abrasive body unit is together with the diagrammatic top view of the baffle plate 11 of this abrasive body unit of side direction bag embedding, the grinding particle AP leaving in demonstration, be depicted as the possible direction of splashing that two travel directions illustrate jointly, to possible improvement structure of the present utility model is described.For simplicity of illustration, the air yet existing on the baffle plate 11 according to Fig. 9 does not have shown in this view for through-flow mouthful 14.A kind of feasible improvement project is importantly shown for this view, the through-flow mouth of the other air of narrow vertical gap 16 forms be also arranged on grinding particle AP hit baffle plate 11, namely this baffle plate is polished in the section 12 that body longitudinal axis 15 passes.Show, in these sections, also can install air through-flow mouthful, and if vertically as long as through-flow mouthful of the other air of gap 16 forms is enough narrow formations, the grinding particle AP hitting just can not be through the through-flow mouth of these air.In this case, can advantageously select approximately 2 gap widths to 3mm magnitude.Larger opening causes grinding particle AP can pass these vertical gaps 16, and narrower gap no longer produces the cooling effect being improved.Spacing between adjacent vertical gap 16 is preferably selected with 40 to 60mm.Here show, little spacing the therefore vertical gap of a greater number no longer provide and obtain effective improved cooling effectiveness, but obviously reduce mechanical stability, and this causes shorten the application life of baffle plate 11.Larger spacing causes cooling effectiveness inadequate on the contrary, thus baffle plate 11 also superheated, mechanical distortion and therefore application life short.
Figure 10 schematically illustrate according to baffle plate 11 of the present utility model together with side face abrasive body 1 here only with two groups form abrasive body unit (shown in dotted line); this baffle plate comprises through-flow mouthful 14 of air and vertical gap 16; wherein; air is through-flow mouthfuls 14 to be arranged in the second section that grinding particle can not hit baffle plate 11 surfaces, and vertically gap 16 is arranged in the first section that grinding particle hits baffle plate 11 surfaces.This actual conditions are particularly shown here, that is, baffle plate (be only illustrated in guide rail both sides guiding here and be arranged on a baffle plate on device) can move on its height and position.This point represents by double-head arrow D, wherein, illustrates that with solid line baffle plate 11 is tilted to (leaving from guide rail) lifting position of outer top, down position shown in broken lines (operating position).
It also shows baffle plate 11 and particularly can there is the side-strut with 17 marks here, on each end face end, there is each side-strut 17, end face end utilize these side-struts (position shown in dotted line) under decline state can be placed on or be pressed in to be fixedly installed on device deposit or stop configurations on (backstops 18 as shown in Figure 11 and 12), so that make like this baffle plate 11 obtain one determines and stable position in the position declining, thereby around the region of guide rail S can be as far as possible can be repeatedly and tight seal surrounded by baffle plate 11, to collect so as much as possible whole grinding particles and prevent that particle from entering environment.Particularly, in the upper area of baffle plate 11, can place the link of aspirator, thereby the particle of tackling by baffle plate 11 in this region is sucked away and can these particles is collected and be left in in the gathering-device on the device of attrition process guide rail for the object of processing in accordance with regulations.From Figure 10, it can also be seen that, baffle plate 11 trough shape ground form and have from the surface of guide rail S inclination expansion.By this structure, the particle that hits baffle plate 11 is deflected into top section from rail head, connect and be preferably arranged on aspirator there and intercept and capture particle there.
To there is air through-flow mouthfuls 14 according to mode of the present utility model and optionally there is the baffle plate 11 of through-flow mouthful of the other air of narrow vertical gap 16 forms in the second section 13 in the first section 12, particularly by metal, particularly formed by stainless steel.
Figure 11 illustrates the baffle plate 11 in down position (solid line) and lifting position (dotted line) to be similar to the view of Figure 10, wherein, and the direction of motion when being also illustrated in baffle plate 11 and rising and decline with double-head arrow D.In this figure, can find out particularly two backstops 18, they are on the framework that is fixed on grinding support (not shown) above guide rail S horizontal plane here and be therefore in operation with respect to guide rail end face, namely vertically go up holding position fixes.In these backstops 18, baffle plate 11 drops to definite position with its side-strut 17 under decline state.Realize the accurate pointing of baffle plate 11 under decline state on the one hand thus, also realize but then these parts certain stability under decline state and also also make it fix.
Figure 12 a and 12b illustrate this point with different views again.At this, Figure 12 a illustrates that baffle plate declines along the direction of arrow P f.Outline line (position of the top), long dotted line (centre position) and solid line (down position completely) with short dash line illustrate three moment photographies.Last position is that better observation illustrates separately again in Figure 12 b.
Can find out the key-way shape profile of side-strut 17 here, the shape common guarantee of itself and backstop 18 is reliably caught side-strut 17 and to side-strut the therefore accurate pointing to baffle plate 11 in decline process and under decline state.
Figure 11 and 12a, 12b illustrate the baffle plate 11 without through-flow mouthful 14 of air and longitudinal slot 16.Also can use in the situation that baffle plate 11 does not punch or cracks although have the solution of backstop, the baffle plate shown in Figure 11 and 12a, 12b has through-flow mouthful 14 of air and/or longitudinal slot 16 equally according to the utility model.They are there only for the former of better general view thereby do not illustrate simultaneously.
