Definitions

  • the present invention is arranged in the field of track ballast cleaning and relates to a modular screening device and the use of the modular screening device for cleaning track ballast that can be removed from a track bed.
  • the present invention relates specifically to the area of track ballast cleaning.
  • dirt has to be removed from coarse, angular gravel stones.
  • the contaminants adhere to the coarse, angular track ballast and have to be removed by massive impacts:
  • cleaning track ballast it is removed from the track bed in a small, limited area below the laid track, freed from adhesions and contaminants and returned to the track bed.
  • the contaminants are usually loosened from the ballast by impact or shaking pulses, separated and ejected/disposed of outside the track bed.
  • the cleaned track ballast - if necessary supplemented with additional fresh ballast - is returned to the track bed, while the cleaning is carried out slowly in a continuous process along a track section.
  • Established devices for cleaning track ballast include: B. in the DE 29 45 767 C2 reveals: Bridge-like structures enclose a cleared track bed area a distance of several meters on both sides. Due to the support points being far away from the cleared area, the track sections floating freely without supporting track ballast will only interact insignificantly with the forces and impulses of the device.
  • devices are also known in which the feet are extended laterally in order to provide a secure, clearly distant support point for the device. The disadvantage of the latter devices is that they can only be operated in sections and not in a continuous process, which means that the cleaning speed is significantly lower.
  • the object of the present invention was therefore to overcome the disadvantages of the prior art and to provide an alternative to the established track ballast cleaning, which, despite its compact design and easier transport, is able to provide sufficient cleaning performance with comparable operating costs.
  • an exclusive track ballast weighing up to 5 tons, modular screening device is designed for cleaning track ballast removed from below the screening device.
  • a vibrating screen deck module sieves impurities from the gravel using gravity and is arranged in a frame module. The vibrations are taken into account in the design by dampening the vibrations of the screen deck using particulate vibration dampers and decoupling the frame and screen deck module from a vibration point of view.
  • the inventors are interested in the use of particulate vibration dampers, such as those in DE 24 52 006 A1 described as an alternative to mechanical vibration dampers is unknown in the area of track bed cleaning.
  • the inventors assume that vibration dampers will not be used because they will naturally initially dampen the vibration itself, i.e. one must assume that the vibrations of the screen deck itself will be hindered, which would prevent good cleaning performance.
  • the inventors attribute this to the fact that, despite the long-standing need, no use or usable device with the claimed features is known or available on the market.
  • the particulate vibration dampers used in the modular sieving device according to the invention have at least one type of particle selected from the group consisting of natural mineral particles, plastic particles, sand, metal particles, metal balls, ceramic balls, plastic balls, packings, ductile steel balls, superficially set - preferably thixotropically set - particles which are arranged in the transition from the screen deck module to the enclosing frame module, with the screen deck module and frame module being decoupled in terms of vibration technology by the particulate vibration dampers.
  • the assemblies are decoupled surprisingly effectively: the vibrations of the screen deck are at best transmitted to the rest of the device in a damped manner with a significantly more diffuse, softer impulse. This trick made it possible for the first time to provide a light, compact screening device for cleaning track ballast, which offers the advantages of a compact design in combination with good cleaning performance.
  • modules are also designed to be 'insertable' into one another and - depending on the module combination - can be combined by adapting the mutual support points.
  • both the individual modules and the device as a whole can be used and exchanged, so that performance characteristics and dimensions of the device are advantageously provided in a versatile manner.
  • Coupling adapters advantageously allow the device to be coupled to systems available on site, provided that the device is designed/used without its own drive unit.
  • the use is preferably characterized in that the ratio of mass of gravel in the screening device to mass of vibration-damping particles is in the range 20 to 1 to 20 to 19, preferably 15 to 1 to 15 to 14, particularly preferably around (0.8 +- 0, 3) is held to (0.2 +-0.15).
  • the use is preferably characterized in that the vibration-damping, ductile particles, as roughly spherical particles with a technically rough surface, have an average size in the range 0.1 to 20 millimeters, preferably 0.5 to 10 millimeters, particularly preferably 6 + - 5 millimeters .
  • the screening device is preferably characterized in that the device, as essentially horizontally oriented, separate modules arranged in a vertical sequence from top to bottom, has at least one gravel feeder with a screening deck and a vibration-damped receiving frame according to one of the usage claims and a usable one that can be adapted to different rail widths Chassis includes.
  • 'Separate' here means that the individual modules are not materially connected to one another, but rather enclose each other, so that the entire device can be lifted via a bottom frame module and inserted into a track, but each module can also be detached separately - if necessary of comprehensive security systems - can be removed and/or replaced.
  • the receiving module and the chassis module are connected via two steel straps (not visible) with several screw holes, whereby the steel straps enable a controlled lateral inclination of the recording module relative to the chassis module when the screws are set at different heights.
  • a specifically adjusted inclination allows the cleaning of long curves in the track, where an inclination of the track level against the direction of rotation of the curve would otherwise result in an asymmetrical distribution of the ballast on the sieve grid.
  • the present device allows the screen deck to be aligned essentially horizontally and permanently, even in inclined track curves.
  • Damping using jet steel balls proved to be particularly advantageous in practical use.
  • 'Blast steel balls' refers to a steel granulate that is known in the area of paint removal as a supplement or additive in the compressed air removal of paint using an air-particle mixture. This granulate, consisting of roughly spherical steel particles, proved to be surprisingly superior: While a sand filling provided poorer damping and, in the long run, the inside of the frame tubes was worn down and even worn through in places, blasted steel balls showed better damping with almost no wear on the inner surfaces of the tubes.
