Definitions

  • the invention relates to a movable liquid cleaning arrangement for rail grooves with the characteristics of The preamble of claim 1.
  • Liquid cleaning assemblies use mechanishes Cleaning organs, in the form of chisels and pressurized water jets that with different arrangements from different directions, also inclined obliquely in the direction of travel, into the rail groove be directed and the loosened groove dirt Rinse.
  • Such a rail groove cleaning arrangement is in the FR 2 628 457.
  • the object of the invention is to provide an arrangement with which is possible a gentle and intense and therefore rapid cleaning and removal of grooved dirt from the To enable rail groove with low energy consumption and the Cleaning performance thanks to a large range to reach between emptying trips and one if possible economical use of the cleaning liquid, usually To make water, possibly with additives, and the Cleaning performance at the usual train speeds. adapt to cleaning at any time without obstructing the To carry out rail transport.
  • the multi-stage design of the separation unit results in a high Trens performance of cleaning fluid and groove aftermath, at which especially the fine particles have great difficulty in Cause separation
  • a vibrating conveyor screen if necessary with upstream falling sieve, enables pre-separation of Part enriched with cleaning liquid and thus one shorter required length of the screen, which is called a cross bar screen with stowage edge by returning the enriched with solid dirt Mixture share from a centrifugal separator on the sieve is constantly flushed, which increases the filtering performance.
  • an upstream prefilter or Decanter can be a very well cleaned cleaning liquid for feeding the pressure generating unit in be stored in the storage device and thereby the fresh proportion of cleaning liquid to be supplied is significantly reduced be, whereby the range of the arrangement and thus the Cleaning performance is increased.
  • the construction of the heavy and large parts of the separation unit based on the carriage frame relieves the guide frame and enables its guidance on the carriage frame with low actuating forces and is particularly advantageous because running in the track that guide attached to the front bogie of the car.
  • a particularly compact device is a vehicle created in which the car frame on at least one front and a rear bogie resting on which the separation unit and the dirt storage unit is set up and on which the guide frame with the cleaning unit pulled out is and which is a stable arrangement for a self-driving vehicle, especially for a rail vehicle results.
