Description
Technical field
The present invention relates to a kind of horizontal chain link, be used for two on the conveyer chain of slat conveyer are linked to each other with the vertical chain link of this horizontal chain link hook, said horizontal chain link has one or more functional areas on the outside away from its inner space.In addition, the invention still further relates to a kind of steel link chain with chain link of each mutual hook, its horizontal chain link by alternating sequence constitutes with vertical chain link.
Background technology
Horizontal chain link is the component part of steel link chain, and steel link chain is used as the conveyer chain that for example is used to drive slat conveyer usually in down-hole coal excavation.Slat conveyer or apron conveyer can have the motor-driven conveyer chain of two annulars, will be fixed on the said conveyer chain in the scraper plate that extends between the chain link and make chain link link to each other.In application corresponding, this conveyer chain also can be used as the center chain in the apron conveyer, especially as two center chain.Under running state, the chain of slat conveyer is pulled through delivery chute, will scoop up through the surface layer such as the coal of scraper plate transportation thus, and is transported to loading terminal.
The horizontal chain link of conveyer chain has functional areas in its side from the inner outward of chain link sometimes.These functional areas for example can be the outsides of structure bar portion, so that with itself and those functional areas of scraper plate bonded assembly.This horizontal chain link also can have functional areas in its arc portion zone.In DE 41 24 788 A1, put down in writing the horizontal chain link that a kind of like this functional areas are positioned at arc portion zone.In its arc portion zone, above-mentioned known horizontal chain link has binding face as functional areas on the opposed outside of longitudinal center's face about chain link each other at two.Along the cross-sectional plane in the outside that chain link vertically points to through two each other at an angle header planes be configured to arrow shaped.Therefore, also be called as the arrow chain through the steel link chain that uses this horizontal chain link to make.In the birds-eye view of horizontal chain link, the tip straight-line extension of the horizontal chain link that forms through above-mentioned header planes.Yet self is spill header planes, so as its can with move flank of tooth place with identical radius of curvature at it and be configured to converx sprocket and be in the plane and fit.The characteristics of said steel link chain are, are used for the binding face of on the mobile flank of tooth of sprocket, fitting, and compare with horizontal chain link, have realized taking turns to the more favourable power delivery of chain by chain in the past.
For straight line portion must have enough length; So that on sprocket, have enough binding faces, with the arc portion zone of bar portion adjacency with the protuberance form via the interval in the bar portion outside each other and in bar portion zone, be made as convex via the outer wide of chain link thus.Because the known outer wide normal width that equal nominal diameter identical round steel chain link of chain link in its bar portion zone therefore according to this conception, can increase the maximum outer wide of chain link.Therefore, in this chain link, by towards chain link in-to-in summit distance between the outside of said protuberance greater than in the longitudinal plane of symmetry zone.This causes again, is hooked into vertical chain link in the above-mentioned known horizontal chain link towards longitudinal center's face of horizontal chain link transversely, only can be hinged according to setting in the zone of longitudinal plane of symmetry.That is to say: have only chain link center aligned with each other, just possibly realize hinged according to setting when mutual hook.Through the said structure of this known horizontal chain link, in the exterior lateral area of bar portion, be formed for connecting the shaped as frame groove of scraper plate.
This conveyer chain processed with this horizontal chain link via chain wheel drive of can hinged property being enough to be used in.Yet, in the chain link of suspension, also possibly there is this situation, promptly horizontal chain link breaks away from the layout of its vertical centering adjustment each other with vertical chain link and swings, and causes vertical chain link to be swung along bar portion direction from the longitudinal plane of symmetry skew with its longitudinal axis.Be in this position like horizontal chain link each other with vertical chain link, then can hinged property (if situation is like this really) very limited.What this just possibly cause not expected kinks.
Summary of the invention
In view of this prior art of being discussed, main purpose of the present invention are to provide a kind of horizontal chain link that is used for conveyer chain, although there are functional areas, said horizontal chain link still can be realized between horizontal chain link and the vertical chain link hinged as far as possible smoothly.
This purpose of the present invention is achieved through the horizontal chain link that starts said type; Wherein, Horizontal chain link annular has identical or essentially identical height continuously; And have the identical or essentially identical width of confirming the nominal diameter of horizontal chain link, and at least one functional areas is provided with respect to the empty side of the height of envelope level chain link in said functional areas and the width mode with inside travelling backwards.
Said horizontal chain link such as standard round molten steel plain link are characterised in that its annular has essentially identical at least height and essentially identical at least width continuously.From gamut, preferably make the little error to the manufacturing process of its height and the difference of width.In arc portion zone, the permissible variation of the geometric configuration of this equal altitudes is at the most-10%.Yet the height minimizing value that is determined by functional areas in the preferred arc portion zone is less than 5% of maximum height.Different is with the design of known horizontal chain link, and the functional areas of this horizontal chain link are located in the enveloping surface of the envelope height and width in each chain sections, thus by the empty side that constitutes through these enveloping surfaces return again upcountry and thus towards the inner space.In this embodiment, the enveloping surface definition of the side of envelope in other words be appreciated that into, all with the interconnective curve of end points of the height and width of horizontal chain link, wherein, height and width and enveloping surface quadrature join in each part.Thereby enveloping surface promptly refers to have annulus or the ellipse of two center-points as the oval curve of closure.Therefore, in this horizontal chain link, functional areas with respect to the layout of enveloping surface outside return ground again and can not hinder and with the vertical chain link of horizontal chain link hook between hinged.Based on this measure, it at first can be hinged smoothly in arc portion, avoided effectively thus kinking.Owing to consider the permissible error in the above-mentioned arc portion, still the height and width in the bar portion are all basic identical at least in arc portion, so the above-mentioned good especially arc portion that can hinged property be not limited in horizontal chain link is regional.For example in standard round molten steel plain link, this can carry out good equally in based on the gamut of horizontal chain link of the present invention or be close to same good hinged at least.Thus, identical with situation in the traditional round steel chain joint is that in the chain link of suspension, the chain link of drawing in each other can be placed in again on the relative position of regulation under tensile load immediately each other.Thereby can understand, for fear of kinking, can make horizontal chain link coordinate each other aspect geometric configuration and the size usually with vertical chain link.Under which kind of situation, all avoiding appearance to cause in the traditional water plain link owing to necessary functional areas kinks.
Horizontal chain link according to the present invention is based on the brand new design.At first, horizontal chain link is approaching the horizontal chain link of traditional round steel as much as possible aspect its geometric configuration.Yet surprisingly, this also have structurized functional areas, and for example special structuring has required intensity with the horizontal chain link of the functional areas that are used for other objects of grasping.At last, structurized functional areas are provided like this in the conventional horizontal chain link, that is, make to apply required structuring from the geometric configuration of round steel chain link.The theme of horizontal chain link of the present invention has provided a rightabout instruction.This design makes that although there are functional areas, yet this chain link also has the weight lighter than conventional link.
What in this design, have decisive significance is that the height and width of horizontal chain link in its bar portion and arc portion keep aforesaid same degree.Can there be deviation between the height and width.Therefore, set so in one embodiment, the height of bar portion and arc portion is greater than width.
According to an embodiment preferred, in birds-eye view, the exterior contour of horizontal chain link is identical with the standard round molten steel plain link with same nominal diameter with outside dimension, perhaps even at least in part is positioned at it.
As the functional areas of this chain link, can the canned paragraph that be designed to the flute profile formula of bar portion be designed for the connection scraper plate.Also can make this horizontal chain link that the header planes that is the arrow shaped trend along the chain link longitudinal cross-section each other is set in its arc portion scope, thereby design this horizontal chain link according to the type of arrow chain link.These functional areas or other functional areas partly are positioned at the side of envelope height and width at least to each function actv. with it.

2 Arc portion 5,5.1 is designed to be looking-glass symmetry with longitudinal plane of symmetry 6.Be positioned at the functional areas F within arc portion 5 lower semisections in this introduction
2Horizontal chain link is designed to so-called arrow chain link.Through functional areas F
2Function associated therewith is provided.Horizontal chain link 3 has separately with respect to the opposed binding face 8,8.1 of longitudinal center's face of horizontal chain link 3.The F in functional areas
2In, arc portion 5 is provided with two header planes 10,10.1 that are the arrow shaped trend each other and constitute edge 9.Header planes 10,10.1 the section-drawing of seeing among Fig. 3 a-3c is set.The cross sectional view of the header planes 10,10.1 of said embodiment is made as vertically.This not only is convenient to functional areas F
2Formation, also be convenient to the structure of the flank profil of sprocket, wherein, said sprocket is fitted in header planes 10 and the header planes 10.1, is used for driving the horizontal chain link 3 of conveyer chain of packing into.
Also show enveloping surface E among Fig. 3 c.Therefrom can find out whole functional district F
2Be positioned at enveloping surface E.
Cross section among Fig. 3 a, 3b, the 3c based on longitudinal plane of symmetry 6 each other angular separation be 15 the degree.In the section line zone of Fig. 3 c, leading edge 9 is designed to form of straight lines on a bit of.Therefore, the height H in the arc portion of height H in this zone and adjacency zone has deviation.Height reduces than the arc portion zone of adjacency slightly in this straight edge section zone.The diagram of Fig. 3 shows that equally also this linear portion at edge 9 is difficult to identification.Header planes 10 and the header planes 10.1 or one of them that constitute this linear portion at edge 9 have constituted sliding surface, the flank profil of the sprocket of the complementary structure of fitting above that when the horizontal chain link 3 of driving.
Shown in the section drawing among Fig. 3 a, horizontal chain link 3 presents a kind of cross-sectional geometry at its arc portion tip, and the width (this width defines nominal diameter N) that wherein extends across longitudinal plane of symmetry 6 is less than height H.In the cross-sectional plane of Fig. 3 a, represent with radius that towards the curvature of chain link inner space 7 it is greater than the radius that defines nominal diameter N (at this being: 26 millimeters).The nominal diameter of horizontal chain link 3 is 52 millimeters; Hatch region inner height H among Fig. 3 a is 54 millimeters.Keep identical owing to see the height of horizontal chain link from its gamut with width, so the height ring-type of said chain link is continuously greater than its width that is limited nominal diameter N.
Geometric configuration about horizontal chain link 3 defineds shows that it can be hinged smoothly with respect to hook vertical chain link within it.Wherein, come to select the setting with the vertical chain link of horizontal chain link 3 hooks like this, make vertical chain link have as far as possible little height and have as far as possible little outer wide and inner width thus.The inside radius of vertical chain link should be suitable for the inside radius of horizontal chain link 3.Yet, referred to herein as common measure.The particular configuration of horizontal chain link 3 shows, the minimum vertical chain link of system height can with its hook, and still realize hinged smoothly and therefore avoid kinking.

Fig. 8 shows vertical chain link 2 single in the steel link chain 1.The inner space 11 of vertical chain link 2 is separated into two activity intervals 14,14.1 independent of each other through the bar portion 12.1 inwardly protruded nose dividing elements 13 from Fig. 8 below.As shown in Figure 8, the distance between the inboard of dividing element 13 and relative bar portion 12 is gone into the diameter of the horizontal chain link 3 of vertical chain link 2 less than hook.Therefore, the hook activity interval of going into the horizontal chain link 3 of activity interval 14,14.1 is subject to these activity intervals 14,14.1.
In Fig. 8, represent the pipe link portion 12 of vertical chain link 2 and the arc portion of bar portion 12.1 with Reference numeral 15,15.1.Each arc portion 15,15.1 forms by half arc portion of two difference extend through an angle of 90 degrees, and said half arc portion (is about to arc portion 15, the 15.1 transversal faces of cutting apart) and crosses each other on longitudinal plane of symmetry 16.Two and half arc portions of arc portion are looking-glass symmetry each other with respect to longitudinal plane of symmetry 16.Therefore, the explanation of double arc portion is enough to characterize arc portion 15 (so same for arc portion 15.1).Below by describing with half arc portion of the below of the arc portion 15 of bar portion 12.1 adjacency among Fig. 8.On longitudinal plane of symmetry 16, the cross-sectional geometry of arc portion 15 is shown in the cross-sectional plane among Fig. 8 a.This cross-sectional plane defines the nominal diameter of vertical chain link 2, this nominal diameter in Fig. 8 a with Reference numeral N
VRepresent.In said embodiment, nominal diameter is 52 millimeters.Therefore, wherein vertical chain link is the chain link of so-called 52 ' specification.Arc portion 15 flat chain link 2 vertically on and thus across nominal diameter N
VDiameter greater than nominal diameter, be 54 millimeters in the present embodiment.The curvature towards activity interval 14.1 of the cross-sectional plane shown in Fig. 8 a has radius R, and this radius is greater than the radius that defines nominal diameter (at this being: 26 millimeters).In the present embodiment, radius R is corresponding to the inside radius R of horizontal chain link 3
i(see figure 2).In the present embodiment, outside radius is greater than the inside radius of representing with Reference numeral R.Shown in the section-drawing among Fig. 8 a, on two outsides respect to one another, arc portion 15 is level, wherein these parallel trends in piecewise, side.As shown in Figure 8, through this design and the transition region that is provided with minor radius, the cross-sectional plane of vertical chain link 2 is bigger than the cross-sectional plane of the vertical chain link of the arc portion with circular cross section.For comparing, in Fig. 8 a, mark this cross-sectional plane in the arc portion zone on its right with vertical chain link 2 of circular cross section with dotted line.
The other end of said half arc portion illustrates through the section-drawing of Fig. 8 g, and this section-drawing has demonstrated the cross-sectional plane of the vertical chain link in the initiation region of bar portion 12.1.This section-drawing is exaggerated than other figure and illustrates.Section-drawing by Fig. 8 g can be found out, the height H of bar portion 12.1
VBe significantly less than the width B of bar portion 12.1
SThe maximum width B of bar portion 12.1
SThe outside 17 skews with respect to bar portion 12.1 prejudicially are provided with, and this helps improving disruption characteristic.Outside the zone of divide element 13, the geometric configuration of the cross-sectional plane of bar portion 12.1 is the groove shape or is similar to half arc portion shape.The identical enforcement of cross-sectional plane of the cross-sectional plane of bar portion 12 and bar portion 12.1.Shown in the birds-eye view of the vertical chain link 2 among above-mentioned Fig. 2, the section-drawing of Fig. 8 g shows that also vertical chain link 2 has maximum width in its bar portion 12,12.1 zones, and shown in the section drawing of 8a, in the zone of longitudinal plane of symmetry 16, has minimum width.Between vertical chain link 2 different in width in its bar portion 12,12.1 zones and in longitudinal plane of symmetry 16 zones, the width that continues that exists in arc portion 15,15.1 zones descends.High-visible relevant formed cut line among Fig. 8 g, the center of this cut line has constituted longitudinal plane of symmetry 16.
Fig. 8 g from the transverse cross-sectional area that shows bar portion 12,12.1; Fig. 8 b to 8f has then showed with opposite numbering; How shape of cross section and cross-sectional area in the half arc portion of arc portion 15 become the longitudinal plane of symmetry 16 shown in the section-drawing among Fig. 8 a, and the bump A of bar portion 12.1 is how with respect to the nominal diameter N that width limited in the longitudinal plane of symmetry 16
VDirection along to longitudinal plane of symmetry 16 constantly reduces.In this change procedure of said cross-sectional geometry, the start-up portion from the end points of bar portion 12.1 or arc portion zone 15 sets out along the direction to longitudinal plane of symmetry 16, the width among Fig. 8 g and (use height H across the diameter that this width extends
VRepresent) between proportionate relationship then be opposite.Vertical chain link 2 the start-up portion (seeing the section-drawing of Fig. 8 g) of arc portion have maximum width and across the minimum diameter of this width (this: height H
V), longitudinal plane of symmetry (sees that Fig. 8 this proportionate relationship a) is then opposite in 16 zones.At this, width (the nominal diameter N of flat chain link 2
V) less than diameter across the arc portion 15 of nominal diameter.
Each cross sectional drawing of Fig. 8 (Fig. 8 a to 8g) is arranged along half arc portion with 15 degree angular separation respectively.In the present embodiment, limit the nominal diameter N of vertical chain link 2 in the arc portion 15 through it
VSection owing to longitudinal plane of symmetry 16 is embodied as almost linearly.Two half arc portions that constitute arc portions zone 15 then are provided with the minimum width of vertical chain link 2 constantly reducing to longitudinal plane of symmetry 16 from each bar portion 12 or 12.1 aspect its width on longitudinal plane of symmetry 16.Wherein design, width reduce ratio with the arc portion zone of longitudinal plane of symmetry 16 adjacency in diminish too.Can see the geometric configuration of the asymptotic wire of bump (representing) in Fig. 8 g thus with A.In Fig. 8 a and 8g, the nominal diameter N of vertical chain link 2
VBe represented by dotted lines and be incident upon in the bar portion 12,12.1.This has shown the size of the protuberance A on the both sides.In the present embodiment, the cross-sectional area of the arc portion shown in the section of Fig. 8 a 15,15.1 in longitudinal plane of symmetry 16 zones is about 0.72 with respect to the cross-sectional area ratio between the cross-sectional area in the bar portion shown in the section-drawing among Fig. 8 g.Therefore, the vertical cross-sectional area of chain link in its bar portion zone is than having reduced about 28% in the longitudinal plane of symmetry zone of arc portion.
As stated, by vertical chain link, can make conveyer chain under highly minimum and situation that weight is lighter, have high effective power.
Fig. 9 and Figure 10 all show above-mentioned flat chain link 2 with the mode of photo analogous diagram.At first, in Figure 10 of the flat chain link 2 that shows the form of keeping flat, can know and find out that the width of flat chain link 2 reduces from bar portion to longitudinal plane of symmetry zone continuously.This figure has also shown, has formed the smooth transition that width is successively decreased up to longitudinal plane of symmetry through each arc portion zone by each bar portion each other gradually.
The present invention is described according to an embodiment.Under the situation of the scope that does not depart from claim, can obtain to those skilled in the art many other can realize scheme of the present invention, but it again needn't be in this embodiment framework be discussed in detail.These schemes equally also belong to the disclosure of this embodiment.
