Definitions

  • the invention relates to a mobile track correction machine, with a track lifting device provided on the machine frame, which can be acted upon by a drive using a reference system, and at least one blower unit with a supporting frame connected to the machine frame for at least one, in the ballast bed on the left and right of the rail on one
  • the blowing-in tube can be immersed and fed with the bedding material from a storage container for blowing in additional bedding material, such as gravel, grit or the like, which has an outlet opening in the area of its tapered lower end on its flattened side facing the threshold is designed to be height-adjustable via a drive connected to a control device and wherein a metering device connected to a drive is connected between the storage container and the blowing pipe - for delivering a Sc hotter crowd - is arranged.
  • blowing process takes a relatively long time due to the slow vibration of the bedding material to the annular gap.
  • a mechanical application of blowing devices designed in this way is also not possible for the reasons mentioned.
  • a manually operated blowing device for fixing to sleeper and rail in which every second sleeper compartment has to be cleared beforehand and the sleepers have to be raised to their correct level in order to blow the ballast then determine.
  • This device has on its gravel container a slot covered by a transparent plate, which lies next to a scale, the digits of which rise from top to bottom, so that the amount of gravel blown in under a threshold can be determined subsequently.
  • This device too, is not suitable for mechanical use in view of the very time-consuming and cumbersome process.
  • a complete and uniform filling of the ballast-free space below the raised threshold is not always achievable in addition to the disadvantage of the strong dust development, since a pressure equalization takes place between the injected and the ambient air via the largely open side of the injection pipe and essentially only the purely dynamic effect of the Compressed air jet transported the stones into the cavity under the threshold.
  • the centering of the injection tube that can be advanced step by step from threshold to threshold in order to immerse it directly next to the threshold into the ballast bed - without damaging the threshold or other track components - is very difficult, especially in comparison to a plunge into the ballast bed Stuffing tool with work-side movement, even more difficult - since the blowing pipe has to be lowered into the sleeper compartment exactly or only a few millimeters away from the sleeper.
  • a mobile track correction machine with a track lifting device which can be acted upon by a drive and a device for blowing in additional bedding material, such as ballast, grit or the like, is under the raised sleepers in the area of intersection with the respective rail.
  • the track lifting device which can be acted upon by means of a reference system or a track height position measuring device is designed for raising and lowering and is connected to a device for measurable raising of the track.
  • the blowing device has one in the ballast bed on the left and one on the right

  • the two injection tubes which are height-adjustable with the support part, also have a stop which is provided for limiting the depth and which can be supported on the raised track, in order to be able to better center the blowing tube against the threshold to be machined when the machine provided with the blowing unit is gradually advanced.
  • the blowing-in pipe and / or also the abutment is also resiliently mounted on the support part which is height-adjustable on the machine frame.
  • a metering device connected to a drive is provided between the storage container and the blow-in pipe - for dispensing a quantity of ballast measured in accordance with the desired lifting dimension.
  • the metering device consists of a metering cylinder which is open on the upper side towards the storage container and on the underside towards the injection tube, is arranged essentially horizontally and cooperates with a metering piston, in which a hollow cylindrical closure part is rotatably mounted and with a cutout corresponding to the openings of the metering cylinder.
  • This track correction machine is therefore largely geared to a real and essentially trouble-free machine application in connection with the metering device, the control device, the reference system for the track height measuring device and the device for measurable lifting of the track.
  • the invention is based on the object of creating a mobile track correction machine of the type described at the outset, with which the blow unit and the blow-in pipes are brought closer and more precisely to the point to be processed in the track or better to the threshold or the track construction or the often changing operating conditions can be adapted.

  • the invention thus enables, for the first time, the surprisingly simple and yet very precise centering or delivery to the desired location in the track, which is located directly next to the sleeper side or the rail, due to the independent height and in particular longitudinal adjustment of the individual injection tubes.
  • This can be done without damaging any track parts, e.g. an inclined threshold, a targeted lowering of each individual blowing tube can be achieved.
  • Even in track bends or when changing track widths or in switches, the transverse adjustment of the blower unit always enables safe and quick centering or precise approach to the rail. The overall work progress is also increased.
