Definitions

  • the present invention relates to an apparatus for operating gates defined in more detail in the preamble of claim 1
  • Such operative apparatuses are primarily used in places without the use of electricity, e g used to open and close gates in fences, designed to protect wild animals and fences designed to mark off pasture land
  • These apparatuses are designed to, when a vehicle arrives to the immediate surroundings of a gate, on either side of the gate, automatically open the gate and after a certain time, when the vehicle has passed the gate opening, close the gate again
  • the object of the present invention is to in combination improve and develop the state of the art in this technical field

Abstract

L'invention concerne un appareil destiné à commander une barrière (U), équipé d'une unité génératrice de pression pouvant être fixée au sol et pourvue d'un cylindre hydraulique (A) ainsi que de ressorts de rappel (O), et qui, au moyen d'un système de circuit hydraulique déclenche un mécanisme d'ouverture et de fermeture de la barrière. Selon l'invention, ledit cylindre (A) est conçu comme un cylindre compresseur primaire, connecté de manière hydraulique en partie à une caisse d'accumulateur (C), afin d'accumuler une partie de la force en surpression, et en partie à un second cylindre d'ouverture (D), afin d'ouvrir la barrière (U) contre la force de la soupape de fermeture (V). La surpression dans le liquide est libérée à travers un conduit dans un réservoir d'expansion (B), à travers un clapet de retenue (G) afin de retarder le processus de décharge. On n'obtient de résultat qu'après le passage d'un véhicule au niveau de l'appareil et de la barrière, et lorsque la surpression dans le réservoir d'expansion a commencé à baisser. Les pointes de pression maximale de véhicules lourds et d'un deuxième et troisième axe de véhicule sont libérées par un clapet de surpression (I) dans le réservoir d'expansion.
