Definitions

  • the invention relates to a conveyor or clearing chain arrangement for track-laying machines, in particular for a ballast bed cleaning machine, for receiving and transporting ballast ballast, with an endless conveyor or clearing chain arranged on a machine frame and guided in a height-adjustable guide channel and connected to a chain drive , wherein the guide channel has a clearing bar located below the track during work and, in the case of an inclined arrangement, a higher discharge point distant from the clearing bar in the machine longitudinal direction and is formed in the transition area to the clearing bar in a direction approximately parallel to the track plane, and furthermore the clearing bar for the purpose of changing the effective clearing width is designed to be pivotable or adjustable in the horizontal plane.
  • Such a conveyor or clearing chain arrangement is already known, according to US Pat. No. 3,850,251, in which an endless conveyor or clearing chain is arranged on the machine frame of a ballast bed cleaning machine which can be moved by rail and is designed such that it can be adjusted in height.
  • the chain is passed under the track grate and further along a machine's long side in an ascending chain guide longitudinal track to a downstream screening plant, into which the ballast ballast is thrown off for cleaning.
  • the chain is then returned to the pick-up point in a longitudinal path leading down the other side of the machine.
  • a chain drive is located at the upper deflection point.
  • the lower ends of the guide channels or chain guide longitudinal tracks, which are remote in the horizontal plane, are connected to one another via a clearing bar which consists of two parts or elements. These elements are connected to both the longitudinal tracks and to one another in an articulated manner and can be pivoted in the horizontal plane - with the V-shaped bend of the clearing beam and spreading of the longitudinal tracks against one another. In this way, the length of the clearing beam which can be brought into contact with the ballast is adjustable, so that the cleaning machine can also be used in switch areas in which the track grate or the ballast bed is wider than on the track.
  • Another conveyor or clearing chain arrangement known according to US Pat. No. 4,614,238 likewise has an endless clearing chain, which is based on chain guide longitudinal tracks and a clearing bar which can be carried out under the track and is constructed in two parts is arranged on the machine frame of a ballast bed cleaning machine in a height-adjustable manner.
  • the two elements of the clearing beam are either articulated or telescopically connected to each other and are adjusted against each other by means of a drive, whereby the length of the clearing beam can be changed to adapt to different track widths.
  • ballast bed cleaning machine in which a broaching member, each with its own endless broaching chain, is height-adjustable on each machine longitudinal side.
  • the clearing elements are mounted on the machine frame so as to be pivotable about a horizontal axis running in the cross-machine direction and are swiveled or lowered into the ballast bed flanks at the start of work, after which they are rotated about a vertical axis into a working position below the track grate.
  • the ballast brought by these clearing elements to the two sides of the track must be transported up to a screening plant using a bucket chain and conveyor belts.
  • a ballast clearing machine described in US Pat. No. 4,882,860 has a clearing member with an endless chain which is height-adjustable on a long side of a machine frame and is pivotally mounted about a vertical axis and can be pivoted in under the track grate for work.
  • the picked up ballast is conveyed up by the chain and thrown onto a transport conveyor belt running above the machine frame in the longitudinal direction of the machine.
  • the clearing element cannot be adjusted in height in its position of use, as a result of which the clearing depth cannot be changed or adapted to different circumstances.
  • the acute-angled deflection of the chain to raise the ballast is complex and associated with increased wear in the arch area. This configuration also makes the space requirement in the area of the sleeper head relatively large, which considerably limits the possible uses in the area of switches.
  • ballast cleaning machine which is equipped on both longitudinal sides with swiveling elements which have an endless chain of clearing and can be swiveled under a vertical axis under the track.
  • the ballast cleared by them to the side of the track bed is lifted conveyed up and deposited on longitudinal conveyor belts for transport.
  • the object of the present invention is to create a clearing chain arrangement that can be used with minimal changeover times in tracks or switch areas with different ballast bed widths.
  • the processing of turnouts is thus possible in particular without any interruption of the machine's right of way, manual retrofitting or a change in length of the clearing chain also being superfluous.
  • the operator only has to use the remote control devices to clear the clearing unit located on the side of the branch track in the work cabin of the cleaning machine adjust in the transverse direction of the track.
  • the clearing chain can be continuously adapted to the changing width of the ballast bed with minimal effort, without having to stop the machine.
  • the measure according to claim 5 is also expedient, thereby ensuring that the ballast entrained by the clearing chain is also completely deflected in the direction of the ascending guideway and is not thrown to the side in an uncontrolled manner by the centrifugal force.
  • each clearing unit is designed in accordance with claim 6, the completely unimpeded pivotability of the clearing unit is thereby advantageously ensured both in the transverse direction of the track and vertically, for example when the transfer position is assumed.
  • the advantage of the development of the invention set out in claim 7 is that the space requirement of the clearing chain arrangement in the area directly next to the sleeper heads is kept as small as possible, so that the cleaning machine even in unfavorable space conditions - e.g. at the point in turnouts where the long turnout sleepers are replaced by normal sleepers - can be used optimally.
  • the design of the arrangement according to claim 8 allows on the one hand the maximum pivoting of the two clearing beams to each other in the normal track, without hindering each other; on the other hand, the greatest possible clearing width is achieved when a clearing unit is fully swiveled out in the turnout area.
  • a broaching chain designed according to claims 9 and 10 can be easily guided around all deflection points and changes in direction of the chain guide longitudinal tracks and the broaching bar in all positions with a minimum of wear and a maximum of safety.
  • the development according to claim 11 provides for the necessary compensation of the change in length of the orbit of the clearing chain when pivoting the clearing bar about its vertical pivot axis, so that the chain remains constant and evenly tensioned.
  • a track construction machine shown in FIG. 1 and designed as a ballast bed cleaning machine 1 has a machine frame 4 which can be moved on a track 3 by means of running gears 2.
  • the working direction of the machine 1 is indicated by an arrow 5.
  • a conveyor or clearing chain arrangement 6 provided on the machine frame 4 consists of two clearing units 7, 8 which are horizontally opposite one another with respect to the longitudinal axis of the machine, each of which has an endless conveying or clearing chain 10 guided in a guide channel and connected to a chain drive 9.
  • Each clearing unit 7, 8 can be adjusted to the machine frame 4 by means of its own height adjustment drive 11 and transverse adjustment drive 12 and for receiving ballast ballast on a bed located under the track 3 Ballast receiving point 13 and transport of this ballast to a higher discharge point 14 arranged downstream in the working direction.
  • ballast falls into a screening system 15 having an eccentric drive and is cleaned therein.
  • a conveyor belt 16 serves to reintroduce the cleaned ballast into or under the track 3, while the overburden is transported away via a conveyor system 17.
  • a track lifting unit 18 is fastened to the machine frame 4 in the area of the receiving point 13.
  • An auxiliary chain 19 is arranged directly upstream of each clearing unit 7, 8 in the working direction. All the drives and units provided on the machine 1, including the travel drive, are supplied with power via an energy center 21 and controlled using an operating device 23 housed in a work cabin 22.
  • Each of the two clearing units 7, 8 has an obliquely ascending or descending longitudinal chain guide track 24, 25 and a clearing bar 26 in the form of a chain guide element 27 which can be pivoted in a horizontal plane to the longitudinal tracks in order to guide its endless clearing chain 10.
  • the two longitudinal chain guide tracks 24, 25 of each clearing unit 7, 8 are arranged directly next to one another in the transverse direction of the machine and are formed in the transition area to the clearing bar 26 in a direction approximately parallel to the plane of the track (see FIG. 1).
  • the chain drive 9 is located in each case at the upper deflection point of the clearing chains 10, which is assigned to the discharge point 14.
  • Each clearing unit 7, 8 is articulated with its upper end region on the machine frame 4, wherein a joint which can move on all sides within a small swivel range can be provided for storage.
  • the chain guide elements 27 or broaching bars 26 are bar-shaped and can be arranged around a vertical pivot axis 28 arranged at one end by means of their own pivoting drive 29 between an approximately parallel position to the track axis 30 (shown in dash-dotted lines in FIG. 2) and an approximately be pivoted in the transverse direction of use. In the latter position, the two broaching bars 26 - as seen in the longitudinal direction of the track - are arranged one behind the other, the length of the in Direction of work of the front broach corresponds approximately to the length of a threshold in the track.
  • a deflection roller 31 At the free end of each bar-shaped chain guide element 27 there is a deflection roller 31 for changing or reversing the direction of the clearing chain 10 guided along both longitudinal sides of the chain guide element 27.
  • each clearing unit 7, 8 is equipped with a deflection plate 33, which is fastened on the outside to the horizontal part of the longitudinal chain guide track 24 and runs vertically and approximately parallel to the longitudinal axis of the machine and serves to deflect the ballast.
  • the clearing chains 10 have clearing blades 34 which - to form the chain - are articulated on all sides by means of universal joints 32. Because of these universal joints, the clearing chains 10 can be deflected in any direction.
  • the broaching chains 10 are guided in the transition area formed by the descending chain guide longitudinal track 25 with the chain guide element 27 pivoted in the cross-machine direction with the aid of guide rollers 35 with vertically running axes of rotation 36 , which are provided with scratch fingers 54.
  • other types of clearing chain guidance not shown here, would also be conceivable in this area.
  • the two clearing units 7, 8 are in the raised position shown in dash-dotted lines in FIG. 1 with clearing bars 26 oriented approximately parallel to the longitudinal axis of the machine
  • the auxiliary chains 19 are lowered into the ballast ballast to the branch track while the machine is slowly moving forward.
  • the respective clearing unit 7, 8 or clearing beam 26 is then lowered using the height adjustment drive 11, while the auxiliary chains 19 are raised again and put out of operation.
  • the clearing beams 26 are pivoted in under the track grating by means of the pivoting drives 29.
  • the clearing unit located on the side of the branch track is continuously adjusted by means of the transverse adjustment drive 12 in accordance with the lengthening switch sleepers. This takes place on the basis of the operating device 23 arranged in the cabin 22 without the machine 1 having to be stopped or the operator having to leave the cabin. If the greatest possible transverse pivoting has been achieved, the chain guide element 27 or the clearing bar 26 in question is rotated parallel to the longitudinal direction of the track, the clearing unit is lifted up and pivoted back into the machine frame 4.
  • a clearing unit 38 of a further embodiment of the invention is illustrated in a very schematic manner in FIG. 3, namely the right hand with respect to a working direction 39 (the clearing unit opposite is not shown here for the sake of a better overview).
  • a conveying or clearing chain 41 driven by a chain drive 40 and guided in a guide channel is formed from clearing blades 42 which are connected to one another via universal joints 55.
  • the clearing chain can be swiveled in under the track at a receiving point 45 using a horizontally pivotable clearing bar 44.
  • the ascending and descending chain guide longitudinal tracks 47, 48 leading the clearing chain 41 to and from a higher-lying, downstream machining point 46 are arranged one above the other - especially in the area adjacent to the sleeper heads 49 of the track 43 - by the width measured in the transverse direction of the track to be able to design the clearing unit 38 as narrow as possible.
  • a clearing unit 38 can also be used if there is only a small free space in the front area of the sleeper.
