Definitions

  • the invention relates to a movable sleeper pick-up machine, in particular in a track renewal train, with a first device for lifting the sleepers out of the track bed and with a second device for lifting the sleepers on a conveyor belt running above the first device in the direction of advance of the machine.
  • the first device for lifting the sleepers consists of a gripping member which can be pivoted about an axis running transversely to the track and with its grippers extending in the direction of advance of the machine during the advancing movement of the machine reaches under the bedding and lifts something.
  • the second device consists of a vertical conveyor equipped with entrainment members for the sleepers, which takes over the sleepers from the gripper member and lifts them to the rear end of a horizontal conveyor belt running in the longitudinal direction.
  • a track renewal train with a sleeper receiving device is known (CH-A-594105), which on the one hand has a rotating wheel with radially projecting grippers for releasing and lifting the sleepers from the bed and on the other hand a tangential to this wheel, against the direction of advance of the machine has upward inclined conveyor belt with drivers.
  • This conveyor belt takes over the sleepers raised by the grippers of the wheel and merges into an essentially horizontal conveyor belt above the device used to lay the new sleepers.
  • this conveyor belt as well as the conveyor belt for bringing in the new sleepers extends opposite to the direction of advance of the machine, which is often unfavorable for reasons of space.
  • the invention has for its object to provide a sleeper recording machine of the type described in the introduction, which makes it possible to raise both single sleepers and double sleepers at a uniform feed speed of the machine regardless of the frequently changing threshold distance and the condition and material of the sleepers and the track bed on the longitudinal conveyor belt , without the risk of jamming and without the sleepers having the base plates, in particular ribbed plates, on the top of the shelf being turned.
  • a sleeper pick-up machine in which the release of the sleepers from the bedding, the lifting of the sleepers and the displacement of the sleepers onto the conveyor belt are each accomplished by separate, simply constructed and controllable organs, which have a defined and also with varying threshold distance ensure trouble-free operation.
  • a driver element For lifting the sleepers out of the track bed and for moving them on the upward inclined ramp, a driver element is preferably used, which can be pivoted back and forth by means of a drive device and has retractable thrust fingers which can be controlled by drive elements; this driving element expediently has the approximate shape of a half circular disk, but can optionally also be designed as a lever which can be pivoted back and forth.
  • the driver element consists of a wheel that can be rotated continuously or intermittently with push fingers that can be pressed in elastically.
  • the driver can be controlled by the operator on the machine by hand in order to take irregularities in the threshold distance into account.
  • the fork-shaped threshold lifter which works like a lever, allows double sleepers to be picked up without any problems, so that the work rhythm does not have to be interrupted.
  • guide plates with appropriately designed lower and rear edges can be provided as leading edges.
  • the arrangement is such that the driver element, which has the shape of a wheel or the approximate shape of a half circular disk, runs with its circumference parallel to the curved top of the ramp and therefore delimits a guideway for the sleepers.
  • This guideway is limited diagonally upwards on the one hand by guide rails and on the other hand by guide levers. As soon as a threshold has been pushed up sufficiently by a thrust finger and rests on the guide levers, these are pivoted downwards together with the threshold so that the threshold can be taken over by the threshold lifter in the orientation suitable for further transport.
  • the machine parts supporting the axis of the entrainment member are preferably suspended on the machine frame so as to be movable in the vertical direction and can be acted upon by a preselectable force in the downward direction by a pressure member.
  • the track renewal train advancing in the direction of the arrow has a transport wagon 2 rolling on the old track 1 for the new sleepers 3 to be laid and the old sleepers 4 removed.
  • the fastenings of the rails of the old track 1 were already loosened.
  • Behind the transport carriage 2 there is a work carriage 5 with equipment for removing the old rails, which are raised and set down on both sides of the track body, with a longitudinal conveyor belt 6 for the old sleepers 4, the starting section 6a of which is inclined, and one above installed, longitudinally running conveyor belt 7 for the new sleepers 3. Since the transport carriage 2 for the sleepers is at the front end of the train, which is advantageous for space reasons, both conveyor belts 6 and 7 extend along the front half of the train.
  • a gantry crane 8 for the sleeper transport can be moved along these two carriages on running rails which are continuously laid on the work carriage 5 and the transport carriage 2.
  • the work carriage 5 rolls with its front chassis 9 on the old track 1, while it is supported with its rear chassis 10 on a carriage 11 which can slide on the old sleepers 4 still in bed.
  • a support frame 14 is mounted, on which the sleeper receiving machine 15 according to the invention, described later in detail, with the inclined initial section 6a of the conveyor belt 6 for the old sleepers 4, a ballast plow 16 for preparing the ballast bed, a device 17 for depositing the new sleepers 3 with the inclined end section of the conveyor belt 7 for these new sleepers and a device 18 for laying the new rails forming the new track 3 are installed; These new rails are placed on both sides of the track before the track renewal train is used.
  • FIGS 2 and 3 show schematically in side view and in plan view the threshold receiving machine 15, only the parts essential for understanding the invention are shown. All these parts are mounted on a frame 20, the front side 20a of which is pivoted about a horizontal axis 21 on a connecting piece 22, which in turn is articulated to the rear end of the chassis frame of the work car 5.

The whole thing thus forms a parallelogram suspension for the vertically movable guide plates 26.
  • a driver element 31 On the upper axis 30 of the parallelogram suspension, a driver element 31 is pivotally suspended with a controllable, retractable thrust finger 32 which, when the driver element 31 rotates counterclockwise in the illustration according to FIG. 2, releases an old threshold 4 which is still in the ballast bedding and moves backwards to the direction of movement of the track renewal train.
  • the old sleeper 4 slides on an inclined fork-shaped ramp 33 which is formed by two vertically oriented plates which are seated on a rear crossbeam 20b of the frame 20.

Therefore, the extension pieces 46a are retracted in the lowered rest position and fully extended in the raised position of the threshold lifter 46. If necessary, the threshold lifter 46 can already be extended somewhat in its lower position when a threshold is lowered by the guide lever 64, in order to ensure a secure fit for this threshold, as illustrated in FIG. 10: the extension pieces 46a are then pushed out further during the upward movement .
