    TECHNICAL FIELD The present invention relates to an endless chain and a ballast apparatus provided therewith for removing and exchanging ballast which is a bedding composed of a number of gravel and ballast the track bed is laid under the threshold to carry the track on the railway track.
    BACKGROUND OF THE INVENTION As a device for removing ballast, which is planned to be exchanged at railroad tracks, a device described in patent document I has hitherto been known. The conventional device is provided with a support member having a pair of standing in a row straight sections and curved portions between the two straight lines, with a pair of sprockets, which are rotatably mounted respectively on the two straight lines of the support member, and with an endless chain, the wrapped around the two sprockets and is supported on the support member and extending along the two straight lines and curved portions of the support member.
    The endless chain comprises a plurality of chain link bases, which are pivotally connected to each other about the Schwenkachslinie and about the other Schwenkachslinie which crosses the aforementioned Schwenkachslinie such that it is extendable along the curved portion of the support member are pivotally connected to each other, a bit for splitting of Ballast of the railroad track supported on each chain link base and projecting into the circumference of the endless chain, as well as a scraper plate for scraping off 1 2/33 • · · · · · · · · · · · · · · · ··· · · · · · ···························································. The conventional device is further provided with a hood which surrounds a part of the endless chain which is supported on the support member and extends along the one of the two straight portions of the support member and the curvature portion.
    According to the conventional device, the endless chain rotates by driving the one of the two sprockets around the two sprockets, so that the bit and the scraper plate, which is supported on each chain link base of the endless chain, along the peripheral surface of each sprocket and along each straight line and the curvature portion of the carrier run in the direction of rotation of the endless chain. If the bit in its current state is pressed against the ballast of the railroad track on the other straight line of the support element, it strikes the ballast and acts to fragment it. The zers chipped ballast, that is, individual gravel or gravel is taken under the action of the scraping by the scraper plate in the direction of rotation of the endless chain. The ballast is further brought by the scraper plate in the hood and transported in the hood to one of the sprockets straightening and then ejected from the hood to the outside. This clears ballast from the railroad track.
    As in the conventional Ballasträumeinrichtung free spaces between the two chain link bases are provided such that the adjacent chain link bases are pivotable about the other Schwenkachslinie around, allow the free space that the ballast stuck during removal work of ballast between the two chain link bases. The ballast inserted into the clearances is then crushed and broken, absorbing compressive force of the two sprockets as the two link bases are pivoted about the other pivot axis line to travel along the curvature portion of the support member, and the clearances between the two link bases bow forward and constrict. This 2 3/33 but verälscht wear or damage to the two Kettengliedbasen.
    However, this also causes vibrations of the endless chain, which again cause transport error of ballast in the hood.

    Support members are extendable bits for splitting ballast on the railway track, which are supported on each chain link base and projecting around the circumference of the endless chain, scraper plate for scrape ballast, and a pair of overlapping parts, which are provided on a pair of chain link bases, which are adjacent to each other which are opposed to the circumference of the endless chain and which are then overlapped with each other when in a position outside each sprocket. The ballasting device is further provided with a hood which is supported on the support member and which surrounds a part of the endless chain which extends along the one of the two straight sections of the support element and along the curvature section. Furthermore, the invention is embodied such that the free spaces, which allow the overlapping of the overlapping parts to pivot about the pivot axis line and about the other pivot axis line, are substantially closed. According to the invention described in claim 3, a rotary motion is produced in the endless chain around the two sprockets around, then when one of the two sprockets is rotationally driven upon actuation of the Ballasträumeinrichtung.
    And when the bits protruding in the circumference of the endless chain which moves along the other one of the straight portions of the support member (the straight sections not accommodated in the hood) with the rotation of the endless chain are pressed against the ballast of the railroad track, they strike the ballast and splinter it, so that the splintered ballast on the other, underlying ballast or on the track bed by means of the current scraping plate are scraped off and transported to the curvature portions of the support element. The transported to the curved sections ballast is in the hood, in which the curved sections and the one of the adjoining straight sections are housed, transported by the scraper plate to the one of the two sprockets directionally. And then this ballast is made up of an opening end, which is provided on the hood, 8 9/33 •······················································································. ejected to the outside, and in that it is optionally further transported by means of conveyor belt, the Entfemungsarbeit of ballast from the railway track can continue to run through. And then by the overlap of the overlapping parts, the free spaces, which allow the pivoting about the Schwenkachslinie and the other Schwenkachslinie, substantially closed.
    In the present invention, since a pair of overlapping portions provided on a pair of link bases constituting the endless chain and adjacent to each other, and which is then overlapped with each other when in a position outside each sprocket, wear or damage can be caused the Kettengliedbasen caused by insertion into the two adjacent Kettengliedbasen during the clearing work of ballast and transport errors of ballast, which cause by vibrations of the endless chain avoid. As the two adjacent link bases move into the perimeter of each sprocket, they pivot about the pivot axis line and, thus, the overlap area content of the surface area opposed to the two overlap portions gradually decreases, leaving clearance between the two overlap portions. But such clearances serve as a discharge space of ballast, which will be explained below: that is, the ballast with a relatively small particle diameter, while running on the straight portion of the support member between the two overlap parts with each other or penetrated by another position between the two chain link bases together can be by means of centrifugal force through the free spaces of the two chain link bases together eject.

    Referring to FIG. 4, each chain link base 45 as a whole has a π-shaped cross-sectional shape and is composed of a generally rectangular base plate portion 51 and a pair of plate-shaped flange portions 53 formed at right angles to each other and perpendicular to the base plate portion. The base plate part 51 defines the outside surface of the endless chain 25, that is, the side surface that faces the outside O of the wheel that defines the endless chain 25. In addition, the free end portion of the two flange portions 53 defines the inner side surface of the endless chain 25, that is, the side surface facing the inner side I of the wheel.
    Each adjacent pair of chain link bases 45 is connected to each other via a link 55 which is a link and a pair of pins 57 which pass both the link and the two adjacent link bases 45 on either side thereof. such that they are pivotable about the Schwenkachslinie. More specifically, a part of the link 55 is disposed between the two flange parts 53 of each adjacent chain link base 45, and each pin 57 passes through the two flange parts 53 of each abutting link base 45 and the link 55. Each pin 57 defines the pivot axis line.
    Further, the connecting member 55 is formed of a pair of comb-shaped block body 59, which engage with each other such that the two adjacent-Kettengliedbasen 45 are pivotable about the other Schwenkachslinie. The two block body 59 are connected to each other by means of pins 61, which pass through the engaging comb-shaped parts. The pins 61 define the other pivot axis line. In addition, the pins 61 shown have a head portion and an adjoining axle portion (not shown). On the one of the two block body 59, a hollow receiving part 63 is provided, which only the insertion 16 17/33 • ·· * · ················································································.

And also, when the two link bases 45 run along the curved portion 41 of the frame 29, they pivot about the pins 61 which define the other pivot axis line.
    At this time, the base plate parts 51 of the two chain link bases 45 lying on the same plane change to the angle-enclosing state.
    The bit 47 and the scraper plate 49 supported on each link base 45 each extend vertically from the base plate portion 51 of each link base 45 toward the outside O of the wheel, thus protruding in the periphery of the endless chain 25. The bit 47 is fixed to the base plate part 51 of the chain link base 45, for example, by welding, or as shown in Fig. 4, is inserted into a detachably attached to the bit 47 mounted on the base plate 51 bit holder 65 and removably. According to the example shown in Fig. 4, the chain link base 45 is not completely replaced when there are wear, damages and the like in the bit 47, but only the bit 47 can be replaced. And also depending on the hardness of too splintering ballast loading and replacement of the corresponding strength or hardness having bits can easily make. In addition, as shown in Figs. 1 and 5, a pattern is formed such that the bit, seen in plan view, in the three, in the running direction of each chain link base 45 successive Kettengliedbasen 45 on the lower stage, on the middle stage and one piece at a time on the upper stage, and the pattern is repeated over the entire length.
    If, in the operating states of the ballasting device 1 shown in FIGS. 1 and 2, part of the endless chain 25 is pressed against the ballast via the straight section 37 of the support element 21 and is driven in rotation, then the bit 18 beats. # · Μ ················································································································································································································ ♦ · · · · · · · ······································································································································· The splintered ballast is scraped off on the other ballast remaining under the endless chain 25 or on the track bed by means of scraper plate 49, and taken straight from the straight section 37 of the support element 21 to the adjoining curvature section 41. The ballast entrained at the bending section 41 is then compressed into the hood 27 which extends along the curved section 41 and the straight section 39 adjoining it and covers part of the endless chain 25.
    The distance between the inner wall surface and the chain link base 45 and scratch plate 49 is set such that the crowded into the hood 27 ballast from the hood 27 does not slide down, but also that the entrainment of the ballast by means of the scratch plate 49 in the hood 27 is enabled. In the example shown, the hood 27 has an overall plate-shaped rectangular cross-sectional shape, and the opposite two inner wall surfaces partially have a circular arc shape. The ballast is conveyed by means of the scraper plate 49 running in the hood 27 to the chain wheels 23 located in the upper position.
    As shown in Fig. 2, a funnel 67 is provided at the upper opening end of the hood 27, with which the ballast conveyed therein can be ejected downwardly outside the hood 27. The ballast ejected from the hopper 67 drops on a conveyor belt 15, which is brought under the hopper 67 and disordered, and transported in a predetermined suitable place by means of conveyor belt 15.
    The two adjacent chain link bases 45 are now, as described above, interconnected at a distance to assure this pivotal movement so that the distance S (Figures 4 and 6) is therebetween. In the present invention, a pair of overlapping portions 69, 71 facing the circumference of the endless chain 25, that is, the outer side O of the wheel, are attached to the two adjacent 19 20/33 • ············································. ··· · # ···············································································.
    Chain link base 45 to avoid trapping ballast in the distance S during ballast removal work. The two overlap portions 69, 71 are then overlapped with each other when the two adjacent chain link bases 45 are located in a location out of the circumference of each sprocket 23, that is, in a location outside each end portion of the support member 21, and the distance S between the two adjacent chain link bases 45 are substantially closed in such a way that the ballast by the overlap of overlap parts 69, 71 does not go into it with each other. As a result, the possibility of origin of wear or damage to the chain link base 45 can be reduced, which is caused by the onset of ballast in the distance S, but also can reduce the possibility of incidence of vibration of the endless chain 25.
    A pair of overlap portions 69, 71 are respectively provided at the two opposite end portions of the base plate portion 51 at the two adjacent chain link bases 45, that is, at the both end portions with respect to the running direction of the link base 45, and are at the periphery of the endless chain 25 opposite. In the example shown, one overlap part 69 has a hook-like shape whose end portion extends beyond the distance S to a point where the other overlap part 71 is covered. The other overlap part 71 is formed from a flat plane, and covered with the end portion of the hook-shaped overlap part 69 at a distance from the end portion. The mutual distance between the end portion of the hook-shaped overlap part 69 and the other overlap part 71 is set to a size with which the ballast infiltrates between the two, taking into account the size of gravel, from which the ballast as the object to be removed is set Overlap parts 69, 71 can prevent. Furthermore, a semicircular notch 75 is provided, which in each case passes through the head receiving part at the two overlapping parts 69, 71. 20 21/33 • ····················································································. The pin 61, which defines the other pivot axis line with respect to the two adjacent chain link bases 45, is permitted.
    But also in the example shown, the opposing plane between the end portion of the overlap portion 69 and the overlap portion 71, which is in relation to a direction which goes from the inside I of the endless chain 25 in the direction of the outer side O, that is with respect to a transverse direction of the endless chain 25, as a pair of conical surfaces formed parallel to each other. By forming the conical surfaces as described above, the increase in the width dimension of the chain link base 45 with respect to the transverse direction of the endless chain 25, which entails the hooked shape of the one overlap portion 69, can be made smaller.
    As shown in Fig. 4 and Fig. 6, the two overlap portions 69, 71 then go from a mutually overlapped state before circumferential rotation to a mutually protruding state, when the two adjacent Kettengliedbasen 45 pivot about the pins 57 to the Circumference circumference of the sprockets 23, so that the distance S between the two overlap parts 69, 71 occurs. But the penetration of ballast in the distance S is difficult. The reason for this is that in the circumferential position of the sprockets 23 a centrifugal force with rotational movement of the sprockets 23 acts on the two adjacent Kettengliedbasen 45, but also by the action of centrifugal force can be ejected, which before the circumferential rotation between the two overlap parts 69th , 71 can be penetrated and pinched. Further, as shown in FIGS. 5 and 6, a hole 73 is provided on the base plate part 51 of each chain link base 45. The hole 73 functions as an ejection orifice which serves to expel the ballast by means of the centrifugal force which exists between the two overlapping parts 69, 71 of the 21 22/33 •·····················································. It is possible to penetrate both adjacent chain link bases 45 or from another point between the two flange parts 53 of the chain link base 45.
    In addition, the two adjacent chain link bases 45 then pivot around the pins 61 as they pass through the curved portion 41 of the support member 21. Thus, the two overlapping parts 69, 71 in the inner peripheral side of the curved portion 41 approach each other and swing in the outer peripheral side in the direction away from each other. In the example shown, in order to allow the overlapping of the two overlap portions 69, 71 with each other in the outer peripheral side at the curved portion 41 to be maintained, the width dimension of the portion 71a which is located with respect to the one overlap portion 71 in the outer peripheral side of the curved portion 41 (direction with respect to running direction of the chain link base 45) is set larger than the widthwise dimension of the portion 71b located on the inner peripheral side.
    Here, with reference to FIGS. 5 and 6, the two edges 77, 79 of the base plate part 51 of each chain link base 45, which with respect to Drehachsrichtung the sprockets 23 (in the upper figure, the upper and lower direction) face each other, each formed so that they draw a circular arc with the same curvature. These circular arcs are each set so as to form part of the two larger circular arcs which extend along the curved portion 41 of the support member 21. On the other hand, when the plural consecutive chain link bases 45 run along the curved portion 41 of the support member 21, these chain link bases 45 which are guided by the support member 21 pivot around the pins 61 so as to extend along the curved portion 41. The fact that the edges 77 are at the two adjacent chain link bases 45 together on the one larger arc, and that the edges 79 are 22 23/33 «·« · ···· · * ·· ···· · · . *** " The one edge 79 of the base plate member 51, which is formed in a circular arc, has a lower resistance to running of the endless chain 25, but also a lower wear of the chain link bases 45, as compared to the fact that the edge extends straight, the contact surface content against the Ballast or the track bed in the Ballastentfemungsarbeit is low.
    In the illustrated ballasting device 1, a plurality of guide members 81 are disposed along the one arc of the bend portion 41 to allow the chain link base 45 to run more smoothly along the curve portion 41 of the support member 21 (see Fig. 2).
    As shown in Fig. 7, the guide member 81 is provided with axis 83 and coaxial rollers 85 which are fixed to the end portion of the axle. Each guide member 81 is arranged such that the peripheral surface of the roller 85 is formed with the one flange portion 53 of the chain link base 45 (in FIGS. 5 and 6 above), more specifically, with the curved surface 86 formed on the one flange portion 53 is contacted, and about the axle 83 surrounding bearing 87 attached to the Tragelcment 21. The roller 85, which contacts the curvature surface 86 of the one flange member 53, rotates by a wear force associated with the movement of the chain link base 45 and causes the arcuate edge 77 of the chain link base 45 to be in concentric relationship with the curvature surface 86 or is in coaxial relationship, is placed on the one arc in the bend portion 41.
    Since in this guide member 81, the bearing 87, which rotatably supports the axis 83, is behind the roller 85 and the ballast, which is required in the hood 27, not facing directly, the operating error of the bearing 87 can avoid 23 24/33 • ···································································································································································· This is due to the fact that small fragments of ballast or dust, which carry along with transporting ballast, into the interior of the bearing 87, penetrate in the example shown between outer race 89 and inner race 91. Consequently, rotational errors of the roller 85 and vibration of the endless chain 25 can be avoided, which damage the conveying performance of ballast and which arises due to the associated insufficient guiding action against the chain link base 45. 24 25/33
