Description
Technical field
The present invention relates to a kind of flat chain link that is used for loop chain, especially conveyer chain; It is thick that bar portion in the vertical direction when chain link is vertically oriented of two arc portions of connection of said flat chain link has a bar; Said bar is thick wide less than maximum rod; The wide in the vertical direction of said maximum rod is provided with prejudicially and towards biasing ground, the bar portion outside, and said maximum rod is wide again greater than the width of said chain link in its arc portion zone, and the width of said chain link in its arc portion zone defines the nominal diameter of said chain link.In addition, the invention still further relates to a kind of steel ring chain, it has the some independent chain link that articulates each other, and one of them in wherein per at least two chain links is this flat chain link.
Background technology
This flat chain link is the component part of steel ring chain, and steel ring chain is used as the conveyer chain that for example moves slat conveyer usually when down-hole coal excavation.Slat conveyer chain scraper conveyer in other words can have two belt, motor-driven conveyer chains, is extending between the chain and chain scraper plate connected to one another is fixed on this conveyer chain.In respective application, this conveyer chain also can be set to medium chain, especially two medium chain in chain scraper conveyer.In when operation, paddled conveyor chain is pulled through delivery chute, and the overburden of carrying through scraper plate thus for example coal is removed and is delivered to loading-unload station.
Steel ring chain preamble, that be configured to conveyer chain according to independent claims is open by DE 103 48 491B3, and this steel ring chain has flat chain link.The flat chain link of this known conveyer chain has protuberance in bar portion zone, compare with the steel ring chain of its manufacturing in other words with relevant, known flat chain link therewith thus, and the anti-disruption characteristic of said flat chain link and then the performance of steel ring chain are improved.Thereby this known bar of flat chain link in its bar portion zone is wider than the width in its arc portion zone.Constitute the wide protuberance of maximum rod and extend into the transition arcs portion section of arc portion and end there.It is adjacent with this transition arcs portion section to have arc portion section unmodified shape of cross section and cross-sectional area, that extend with about 80 to 100 degree.The cross-sectional plane of this arc portion section is circular.Therefore, this arc portion section limits the nominal diameter of this known flat chain link with its unmodified shape of cross section and cross-sectional area.The nominal diameter of this chain link is equivalent to the width (longitudinal extension transverse to chain link measured) of this chain link in its arc portion zone.Therefore, this known minimum diameter of flat chain link in its arc portion zone defines the nominal diameter of this flat chain link.Shape of cross section and cross-sectional area unmodified arc portion section help the hinged property of flat chain link with respect to another chain link of hanging this flat chain link, and said another chain link is hinged on this arc portion section of flat chain link with its arc portion inside face.
The disclosed steel ring chain of DE 103 48 491 B3 is based on its good stable property and life-span and get a good review.Because other chain link identical with nominal diameter compared, this flat chain link has good anti-disruption characteristic and stability based on its special design, and however, this flat chain link is but lighter relatively.The less relatively reason of the weight of this known flat chain link is that in the flat chain link of known steel ring chain, the cross-sectional area of bar portion reduces with respect to the cross-sectional area in the arc portion zone that limits nominal diameter.The cross-sectional area in bar portion zone is merely 0.55 to 0.85 of the regional cross-sectional area of arc portion.
Although this flat chain link has been given the steel ring chain special performances by its manufacturing; Make that steel ring chain is reliable especially and have higher anti-disruption characteristic; But there is such hope all the time, that is, aspect its anti-disruption characteristic, further improves this known flat chain link; Thereby, have stronger load-bearing capacity generally and can satisfy higher burden requirement in other words using this steel ring chain, especially being used as under the situation of conveyer chain by flat chain link manufacturing.
Summary of the invention
Therefore, the present invention based on task be a kind of so flat chain link of suggestion.
According to the present invention; The flat chain link of this task through the said type of preface is able to solve, and wherein, the zone of said arc nominal diameter portion, that define said chain link is limited in the arc portion section that comprises the several years angle; Said arc portion section has longitudinal plane of symmetry both sides with cross-sectional said arc portion at a distance of the maximum angle that is about 10 degree; Be preferably 5 degree or littler angles, and, from the wide beginning of said bar; The width at its arc portion place of said chain link reduces gradually, until the arc portion section that limits said nominal diameter.
In said flat chain link, the arc portion zone that limits nominal diameter is restricted to low-angle.This means, adjacent with the arc portion section that limits nominal diameter, increase towards the width of the chain link of bar portion direction.Otherwise, this means that from the wide beginning of the bar of chain link, this width reduces at arc portion place gradually, until the arc portion section that forms nominal diameter.Protuberance (it has its maximum width in bar portion) with respect to the arc portion section structure that limits nominal diameter extends to arc portion place; Until the arc portion section that limits nominal diameter; Or rather; Reduce gradually under the situation in the protuberance value, that is: this protuberance value is the width of protuberance and half of the difference between the nominal diameter.The characteristics of this chain link are its waist, and said waist can be seen in arc portion view usually.
Experiment shows, requires the flat chain link of protection to compare with the disclosed flat chain link of DE 103 48 491 B3, and under the identical situation identical with material of nominal diameter, anti-disruption characteristic improves 8% to 10%.Be stressed that in the case, because the raising of this performance can not realize under materials used have the situation of significantly increase, so the raising of this performance can not realize under flat chain link weight has the situation of obvious increase.Reason is that ingenious embodiment and the zone that in its arc portion, limits the chain link nominal diameter of the geometric configuration of flat chain link approximately are reduced to minimum value.
In a preferred implementation, towards the arc portion section that limits nominal diameter, protuberance value gradually and the said protuberance that reduces continuously in longitudinal plane of symmetry, converge each other, therefore, in this embodiment, the arc portion section that limits nominal diameter approximately is reduced to a line.The preferable width reduction rate said arc portion, with the arc portion section adjacent areas that limits said chain link nominal diameter in reduce gradually, to realize progressively transition to the arc portion section that forms nominal diameter.On this meaning, the width reduction rate is not constant at least in said zone.This width reduction rate can be constant in other arc portion section.This also can begin from bar portion, and width at first reduces with bigger value, this reduction rate transition then, and till arc portion section, in said arc portion section, the width reduction rate progressively reduces, till nominal diameter.
The further raising of performance realizes in the following manner: said chain link in limiting the section of its nominal diameter transverse to the diameter of said nominal diameter greater than said nominal diameter.This means: in the arc portion section that limits the chain link nominal diameter, the diameter of flat chain link on the chain link longitudinal extension is greater than transversely diameter.This measure has improved the rigidity of arc portion section, and this has further improved anti-disruption characteristic under the situation according to the embodiment of the present invention that combines said chain link.
Replace or additional above-mentioned measure; The performance of flat chain link and then its anti-disruption characteristic can also improve in the following manner; Particularly; The sensing chain link in-to-in curve that limits the said arc portion section of each half one of arc portion at said longitudinal plane of symmetry place is beginning to have radius the section through the 40-50 degree at least from said longitudinal plane of symmetry, said radius is half the greater than said nominal diameter.Particularly preferably be, said radius is equivalent to hang the inside radius into the said arc portion of the chain link of said flat chain link.In this embodiment, not only to contact each other under tensile load with its arc portion inner region chain link against each other, but contact each other with the line or the face way of contact with a way of contact.
As stated, steel ring chain is using other chain link that also has the flat chain link of corresponding connection under the flat chain link situation, and these chain links preferably have bigger inner width, and said inner width is preferred only wide greater than the maximum rod of flat chain link with required free gap.This has guaranteed, for example when links was crossed the sprocket wheel guiding and moved, flat chain link can fully stretch into the chain link that connects two flat chain links.Certainly, steel ring chain also can only be made by aforesaid flat chain link.

The arc portion of the pipe link portion 4,4.1 of flat chain link 2 representes with Reference numeral 8,9 in Fig. 3.Each arc portion 8,9 comprises two half arc portions of all extending 90 °, and said half arc portion is engaged with each other in longitudinal plane of symmetry 10, and longitudinal plane of symmetry 10 is meant the plane of cross-sectional arc portion 8,9.Arc portion 8 or 9 two and half arc portions are about longitudinal plane of symmetry 10 mirror images of each other symmetry.Therefore only need explanation one and half arc portions just to be enough to show the characteristic (also is the same for arc portion 9) of arc portion 8.Next combine arc portion 8, half one adjacent with bar portion 4.1 in Fig. 3, below being positioned at describes.In longitudinal plane of symmetry 10, arc portion 8 has a cross-sectional geometry, like it shown in the cross sectional drawing of Fig. 3 a.This cross-sectional plane limits the nominal diameter of flat chain link 2.This nominal diameter is represented with Reference numeral N in Fig. 3 a.In the embodiment shown, nominal diameter is 52mm.Therefore, this flat chain link is so-called No. 52 chain links.Arc portion 8 flat chain link 2 on vertically so that be 54mm transverse to the diameter of nominal diameter N in the embodiment shown greater than this nominal diameter and this diameter.The curve of the sensing motion space 7.1 shown in the cross sectional drawing 3a has radius R, and this radius R is greater than the radius (is 26mm at this) that limits nominal diameter.In the embodiment shown, radius R is equivalent to the inside radius R of horizontal chain link 3
i(referring to Fig. 2).It is arc portion 8 that (a) also have a radius referring to Fig. 3, this radius is greater than the radius of nominal diameter in the longitudinal plane of symmetry zone with curve excurvation pars convoluta opposite each other sensing motion space 7.1.In the embodiment shown, this outside radius is greater than the inside radius of representing with Reference numeral R.Shown in section-drawing 3a, arc portion 8 is scabbled on two outsides opposite each other, extends parallel to each other at this this two lateral parts.As shown in Figure 3, through this design and interconnecting gangway with minor radius, the cross-sectional area of flat chain link 2 with have cross-sectional plane and compare for the cross-sectional area of the flat chain link of circular arc portion and strengthen.For comparing, in Fig. 3 a, in the arc portion on the right side at flat chain link shown in broken lines, cross-sectional plane is the cross-sectional area of circular this flat chain link.
The other end of half observed arc portion is shown in the section-drawing 3g, and this figure has been illustrated in the cross-sectional area of flat chain link in the starting point zone of bar portion 4.1.This section-drawing and other section-drawings are in a ratio of enlarged drawing.Can find out that from the viewgraph of cross-section of Fig. 3 g the thickness H of bar portion 4.1 is significantly less than the width B of bar portion 4.1
SThe maximum width B of bar portion 4.1
SBe provided with prejudicially and towards the 11 biasing ground, the outside of bar portion 4.1, this has improved anti-disruption characteristic.The geometric configuration of the cross-sectional plane of bar portion 4.1 is approximate half-circular in other words in the form of slot except the zone of dividing element 6.The cross-sectional area of bar portion 4 is identical with the cross-sectional area of bar portion 4.1.It has been seen in that and section-drawing 3g also is clearly shown that from the birds-eye view of the flat chain link 2 of Fig. 2, flat chain link 2 in its bar portion zone, have its maximum width and by Fig. 3 longitudinal plane of symmetry that a is shown in 10 in have its minimum width.Between the different in width of flat chain link 2 in its bar portion zone 4,4.1 and longitudinal plane of symmetry 10 zones, in the zone of arc portion 8,9, width reduces gradually.In Fig. 3 g, can be clear that, the waist that forms thus, the waist center constitutes longitudinal plane of symmetry 10.
Accompanying drawing 3b to 3f illustrates with reverse numbering; Shape of cross section in this half arc portion of arc portion 8 and cross-sectional area are how to begin to change towards longitudinal plane of symmetry 10 (3a illustrates by section-drawing) from the transverse cross-sectional area of bar portion shown in Fig. 3 g 4,4.1, and the protuberance A of bar portion 4.1 to be nominal diameter N of how limiting with respect to the width longitudinal plane of symmetry 10 reduce towards the direction of longitudinal plane of symmetry 10 gradually.In this change procedure of cross-sectional geometry, width and transverse to the relation between the diameter of width (in Fig. 3 g through thickness H explanation) from the end of bar portion 4.1 in other words the starting point of arc portion 8 begin to reverse towards the direction of longitudinal plane of symmetry 10.On arc portion starting point (referring to Fig. 3 g), flat chain link 2 has its maximum width and its minimum diameter transverse to this width (being thickness H here), and this pass ties up in longitudinal plane of symmetry 10 zones and reverses (referring to Fig. 3 a).At this, width (the nominal diameter N of flat chain link 2) is less than the diameter of arc portion 8 transverse to nominal diameter.
Each cross-sectional plane of Fig. 3 (Fig. 3 a to Fig. 3 g) along half arc portion respectively at a distance of 15 the degree angular distance.In the embodiment shown, the section that passes longitudinal plane of symmetry 10 of arc portion 8 approximately is configured to a line, and said section limits the nominal diameter N of flat chain link 2.Two and the half arc portions that constitute arc portion 8 dwindle towards longitudinal plane of symmetry 10 from respective rods portion 4 or 4.1 beginnings on width gradually, and are minimum at the width of this flat chain link 2 in longitudinal plane of symmetry 10 places.In this regulation, the width reduction rate is reducing with longitudinal plane of symmetry 10 adjacent arc portion section places too.This shows in Fig. 3 g the asymptotic geometric configuration of visible protuberance with the A mark.In Fig. 3 a and Fig. 3 g, be represented by dotted lines the projection of nominal diameter N in bar portion 4,4.1 of flat chain link 2.This clearly expresses the degree of both sides protuberance A.In the embodiment shown, cross-sectional area (as section-drawing 3a shown in) and the cross-sectional area ratio cross-sectional area (as section-drawing 3g shown in) in bar portion between of arc portion 8,9 in longitudinal plane of symmetry 10 zones is approximately 0.72.Therefore, this is upright medium and small by about 28% to the longitudinal plane of symmetry zone in arc portion that the cross-sectional area of chain link in its bar portion zone compares.
