Definitions

  • This invention relates to an electromechanical barrier with a movable bar powered by a gear reduction unit, and refers in particular to an innovative supporting device of the shaft of the gear reduction unit controlling the bar.
  • An electromechanical barrier of the type taken into consideration usually comprises a movable bar attached to and rotating with the shaft of a reduction unit fixed in a structure or supporting column, and at least one elastic means associated with said shaft for balancing of the bar in its movements.
  • the elastic means is loaded when the bar moves from the open to the closed position cooperating then with the opening of the bar, and it can be made up of one or more spiral, helical or leaf springs, with one end connected to the rotating shaft and the other end fixed to the supporting structure or column.
  • the body of the gear reduction unit is fixed in the structure or supporting column with a disposition that is basically projecting, and the shaft to be connected to the bar to be controlled is supported only in two parts of the body of the gear reduction unit with interposition of bearings.
  • This condition seems to be mechanically unfavourable in that the shaft, when it is under stress, tends to oscillate together with the body of the gear reduction unit, in particular if the bar to be controlled is very long and subject to significant inertia.
  • One of the objectives of this invention is to effectively remedy such a drawback by using a more correct and rigid support for the shaft designed to control the opening and closing movements of a bar.
  • a further objective of the invention is to provide an electromechanical barrier where the rotation axis of the bar is stabilised by the use of simple additional means which are to a large extent irrevelent to the traditional configuration of the device, so that it does not feel the effects of the stress deriving from the movements of the bar, even if the latter is particularly long and heavy.
  • the barrier proposed herein comprises a column supporting structure 11, a gear reduction unit 12 connected to the supporting structure 11 and provided with an exit rotating shaft 13, a movable bar 14 controlled by said rotating shaft 13 for its opening and closing movements, and one or more springs 15 balancing the movements of the bar.
  • the supporting structure 11 is anchored to the ground and normally enclosed in a casing 16.
  • the gear reduction unit 12 is fixed, through its body 17, to the supporting structure 11 as shown in the drawings, so that its rotating shaft 13 extends horizontally.
  • This shaft 13 is supported in the body 17 of the reduction unit in two parallel parts, by means of rolling bearings 18, and has one of its ends 13' facing towards one side of the supporting structure 11 where it is fixed to the bar 14 to be controlled.
  • the balancing spring/springs 15 have one of their ends connected to at least one lever arm 19 fixed to rotating shaft 13 and an opposite end -not shown- attached to the supporting structure.
  • the other end 13" of the rotating shaft 13, opposite to the one supporting the bar 14 to be controlled extends out of the body 17 of the gear reduction unit towards an additional supporting means 20, outside said reduction unit.
  • the additional supporting means 20 consists of a vertical plate 21 fixed, by means of bolts 22, to at least two crosspieces 23 associated with and connected to the supporting structure 11.
  • the plate 21 has a housing 24 in one of its intermediate parts designed to receive at least one rolling bearing 25, and the end 13" of the rotating shaft is coupled to and supported by said rolling bearing 25 as shown above all in Fig. 3 .
  • the rotating shaft 13 designed to control the opening and closing movements of the bar 14 is supported, other than by the bearings in two internal parts at a distance from the reduction unit , also by a third part by a stiffening of the functional system.
  • supporting plate 21 may also be used as a means for accepting the electric end of stroke devices 26 designed to set the opening and closing positions of the bar.
