Definitions

  • the present invention refers to Physics,class G 02,and Electricity,class H04.
  • the current technique involves the use of a theodolite which must be manually set by a skilled operator in order to survey technical data.
  • the peculiarity of the present industrial invention is to have made possible the survey of the data through the emission and reflection of a laser beam from a sophisticated theodolite fixed on railway engine or a train,even moving at high speed.
  • the instrument is hanging and sliding inside a container in order to guarantee its own constant vertical order and an external range not lower than 180° each side. It is revolving on its own axle, with reference to the movement and the speed of the train wheels.
  • More than one reflecting components are applied on poles and/or pylons and/or similars,permanent and parallel to the rails.
  • the instrument and the reflecting components together are able to survey the stability both of the pole (tab.1/2,fig.1(a)), and of the railway (tab.1/2,fig.1,(a4)), or of the two at the same time.
  • the movement of the instrument is syncronized to the train wheels' one in order to complete 90 degrees within the distance of a 1/4 of a perfect circular trajectory with a 60 metres radius,and 180 degrees within the distance of a 1 /2 circunference.
  • the reflecting components on all the poles,but, alternately,only on the half part of them.
  • the reflecting component will be alternately applled only on to 4 poles (tab.2/2,fig. 7,(g,g1,g2,g3)),and not on to the 9 existing and if the engine's speed will be 215 km/h, the instrument will complete n° 2 rounds on itself, performing n°12 surveys.
  • the line marked out by the engine won't be 180 degrees along the curvilinear trajectories,making an angle 24° less along the rectilinear trajectories.As a consequence,the instrument will be able,while working,to survey the railway line,too.
