Definitions

  • the present invention relates to an automatic lifting barrier for the access control of vehicles, in particular on toll roads, at the entrance and exit of motorways, tunnels, bridges, etc.
  • the arms In horizontal position, the arms, in horizontal position, are indeed exposed to the shocks of vehicles that do not stop in time and hit them.
  • various unhinging systems are used to release the arm by allowing its end fixed on the mechanical drive head. to dissociate itself from its support beyond a certain impact force.
  • FR-A-2 602 806 or FR-A-2,759,399 such barriers are described and among the known stripping systems are those of FR-A-2 602 806 , FR-A-2,759,399 , FR-A-2,800,759 .
  • a liftable barrier comprising a mechanical head fixed on a support and driving an arm in rotation in a vertical plane, a release device allowing the arm to retract in case of collision by a vehicle or equivalent, the disengaging device comprising a means of connection between the support and the head adapted to allow the pivoting thereof (a priori in a horizontal or substantially horizontal plane) relative to said support, to a disengaged position.
  • a problem posed is to provide a dismounting device providing security vis-à-vis vehicles and that is quite simple.
  • a solution to this problem is a barrier characterized in that the stripping device comprises an adjustable clamping means which establishes a mechanical connection with friction between the head and its support with a rotational braking effect of this head when it s 'escamote and who is able to adjust the threshold of the force of impact beyond which this retraction takes place.
  • the rotational friction force of the head with respect to the foot may be substantially constant.
  • the head of the barrier is imposed in the invention , a force that decreases as the barrier is rotated by the vehicle.
  • the clamping means comprises a plate whose at least one surface has a low coefficient of friction and is arranged against a platen secured to either the head or the support, the plate then being secured to either the support or the head, and a compression device able to maintain a given tightening between the plate and said plate.
  • the pivoting retaining force of the head can thus be in particular a function of the clamping force of compression nuts, via washers.
  • a corollary problem concerns the control of the movement of the arm.
  • Another problem posed is to return the mechanical head of the barrier in the normal operating position, after unhinging has rotated, using means relatively simple, with a controlled cost, without requiring delicate human intervention involving a particular training of an operator, nor a complex winding and while respecting the standards of road safety.
  • this finger defines an elastic blade preferably having a width of between about 10 and 16 mm.
  • the barrier of the invention comprises a motor for rotating the arm in the vertical plane, in the normal operating position, and that the motion transformation mechanism is driven by this motor, by via a connecting rod printing reciprocating rectilinear movement to said pushing means, preferably to the finger (the rod then being advantageously engaged on a shaft to which the arm is connected for its rotational drive in the vertical plane).
  • the same motor and the same movement transformation mechanism can be used both to maneuver the arm in normal operation and for the return of the head after disengagement, thus favoring the adaptation of the solution of the invention to barriers existing, while limiting the number of parts to be added to obtain the return function according to the invention.
  • Yet another characteristic advises, to automate the return of the barrier in the normal operating position (or even allow remote control of this return), to use in particular the (s) sensor (s) already planned (s) position angular position of the head relative to the support and / or the arm and the associated electronics in such a manner that a detent rotation detection of the head causes the oscillatory control of the arm during the return movement of the head after disengagement and, preferably, that at the end of stroke back of the finger, while the head returns to the normal operating position, these means control a greater oscillation amplitude of the arm, to clear the finger of the last stop of the series, then allowing the free rotation of the arm in its normal plane of operation.
  • the mechanical head In normal operating position, as on Figures 1 to 3 , the mechanical head is designed to move the arm 3 from the horizontal position as shown in FIG. figure 1 in the vertical position along the plane VV ', and vice versa and this while respecting certain parameters.
  • the arm 3 is kept at rest, in the vertical position by a spring 15.
  • the torque motor 8 When an order to lower the arm to the horizontal position is given the torque motor 8 is energized and its output shaft 8a rotates a crankpin 12 which itself drives in a circular motion a rolling bearing or roller 13 which moves back and forth in a slot 16 of the connecting rod; by construction, a rotation of the pinion of 270 ° for example causes a rotation of the connecting rod of 90 °.
  • the bearing 13 presses against a stop 19 made of high-density rubber which serves to dampen shocks and vibrations.
  • the shaft 9 rotates on two bearings 10 mounted in opposition on the support part 7.
  • the energy accumulated by the spring serves either to relieve the engine 8 in the raising movement of the arm, or raising the arm 3 to the vertical position, in the disengaged state of the head 1. This state is reached when there has been a power failure of the engine or in the solution below.
  • the opposite end of the shaft 9 receives a support 6 for the arm 3.
  • the support 6 can be fixed on the shaft 9 by two pins and at its other end the shaft 9 can be associated with a position sensor 17 angular which allows to control at any time the angular position of the arm.
  • the device for disengaging the barrier comprises a means 4 for securing between the support 20 and the head 1 able to allow the movement thereof in the horizontal plane HH 'relative to the support 20.
  • the securing means 4 is here constituted a single screw or equivalent 4 which extends along the vertical axis XX 'and maintains a part 7 of the head, while allowing the rotation of this part relative to the support, about said axis XX'.
  • the part 7 can serve as a support for all the mechanical elements of the head against the support 20, as shown in FIG. figure 2 .
  • this support 20 may be that of the boot foot 2 when the head 1 is mounted therein: in this case the release device may be disposed between the lower sole 21 of the foot box 2 and the support 20 'fixed on the ground and on which are then fixed both the head 1 and the foot of the barrier, the latter then pivoting with the head 1.
  • the pivoting of the head 1 relative to the support 20 this also relates to the solution of the pivoting of the entire head and foot relative to the support 20 'anchored to the ground.
  • the disengaging device comprises a means for clamping the mechanical head 1 on the base 2 adapted to adjust the braking and rotational damping of the head 1.
  • This clamping means comprises a sliding plate 5 (at least one surface plane is of low coefficient of friction and arranged against a flat plate 7 1 ) and a compression device 25 able to maintain a given tightening between the patina 7 1 and the plate 5.
  • the platen 7 1 may be a part integral with the head 1, as shown in FIG. figure 2 either of the support 20 and vice versa for the plate 5.
  • the mechanical head 1 is thus clamped through the screw 4 in a hole located here in the center of the support 20 which is the upper plate of the box foot 2.
  • the round plate 5 by example polyethylene
  • the round plate 5 fixed in the example described on the support 20, facilitates the sliding in rotation of the head 1 vis-à-vis the support foot.
  • the compression device 25 may consist of two spring washers 25 1 , immobilized and compressed by a lock nut 25 2 screwed onto the screw 4, with a suitable clamping force. As soon as a horizontal force is applied to the arm 3, the assembly of the mechanical head 1 and of the arm 3 then rotates along this screw axis 4; the clamping force of the latter by the compression device 25 allows the slowdown of the rotational movement.
  • the plate 7 may have an asymmetrical U-shape consisting of a single piece whose large branch 7 3 of the U receives the drive motor 8 of the arm, the small branch 7 2 receives in an open slot 24 a bearing support of the drive shaft 9 of the arm 3 and the web 7 1 of the U receives the securing means of the unhinging device, such as through a square hole to position the screw-axis 4 shouldered.
  • the disengagement rotation is limited to a quarter of a turn by a mechanical stop secured to the plate 7 and sliding in a long slot 22 of the plate 5 (which may have the shape of the figure 2 or from figure 4 ).
  • the pivoting arm releases the passage A ( figure 1 ): at the end of rotation the arm can optionally continue to operate freely without causing any problems since it is always integral with the head 1 and is parallel to the access path A along the curb.
  • a sensor 18 of angular position around the vertical axis XX 'of the head relative to the support 2, 20, fixed to the plate 7 and rotating in the slot 22 acts on the drive motor 8 of the arm 3 from the beginning turn of rotation of the head 1 (for example 5 °) and the arm 3 then rises vertically under the impulse of the motor 8 at low speed.
  • the switch 18 may also signal the disengaged position at the monitoring station.
  • the contactor 18 which thus controls the rotation of unstacking / return of the plate 7 relative to the foot 2 (support 20) and the position sensor 17 which gives the direction of rotation of the shaft 9 thus participate in the electronic management of the parameters. of movement of the arm and the head, both in normal operation and disengaged situation.
  • Such a rod / ratchet / rack assembly defines, advantageously with the motor 8 and the associated control logic (in particular the sensors 17, 18), most of the return means which will allow to recall the head 1, and in particular the arm 3 in the normal operating position, after disengagement, taking advantage of the possibility of then oscillate the arm 3 by a few degrees around an established position, which position is typically its vertical or substantially vertical safety position, as on the figure 4 .
  • the motor 8 and the associated geared motor device are used for the operation of the arm 3 both during its normal operation and its oscillatory movement thus allowing the head 1 to return to the normal operating position of the arm , we will be able both to limit the number of parts added to ensure this automatic return function, to use only one motor and a single mechanism for the two types of movement of the arm 3 and thus allow to adapt on existing barriers the automatic return device according to the invention, without significant modification.
  • the arm of a moment which, taking into account the actual dimension of the barrier, substantially compensates for the torque is arranged with respect to the pivot axis 3a. to overcome because of braking disengagement (typically 5 m.kg).
  • the sensors 17 and 18 are connected to the electronic control unit 33 which controls the operation of the arm 3, via the motor 8, as a function of the angular position of the head 1 (normal operating position or more or less disengaged).
  • the electronic control unit 33 provided with a programmable microprocessor and a memory unit thus defines two modes of angular movement of the arm 3: oscillatory operation of a few degrees around the vertical in disengaged mode or rotation between vertical and horizontal in "normal" mode.
  • the head 1 rotates at an angle about the axis XX 'from its initial position (normal operation).
  • the electronic control unit 33 is then informed by the sensor 18 that a certain angle of rotation of disengagement has been applied to the head 1 and that the movement of the arm 3 must be modified.
  • the arm 3 then rises in a vertical position.
  • the finger 30 Since the head 1 has rotated, the finger 30 also meshes with one of the abutments (teeth) 31.
  • the electronic control unit 33 then activates the motor 8 so that in connection with the sensor 17, the arm oscillates about 5 to 10 ° with respect to the vertical, around 3a ( figures 6 and 7 ).
  • the arm 3 begins its first oscillation.
  • the finger 30 then moves under the effect of the rod 11 and applies a substantially horizontal force on one of the stops of the toothing 31 which can be located radially at about 10 to 20 cm from the axis XX '.
  • the reaction of the tooth generates a torque which causes the rotation of the head 1 tending to bring it back to its initial angular position.
  • the angle of rotation step by step of the head will advance tooth by tooth or more, this being a function of the tolerated movement of the arm relative to the vertical and meshing dimensions between the finger and the teeth .
  • the finger 30 is then advantageously in front of the part 31a without toothing, thus allowing the arm 3 to regain its possibility of free movement between its horizontal and vertical positions of normal operation ( figure 8 ).
  • the senor 18 has advantageously transmitted end of travel information of the finger 30 to the control means 33, so that via the microprocessor a control command of the motor 8 has been generated so that at the end of this stroke a greater oscillation amplitude is applied to the arm 3 (for example up to 15 °) to release the finger from the last tooth and allow the free rotation of the arm (the finger then being at a sufficient distance from the last tooth).
  • a control command of the motor 8 has been generated so that at the end of this stroke a greater oscillation amplitude is applied to the arm 3 (for example up to 15 °) to release the finger from the last tooth and allow the free rotation of the arm (the finger then being at a sufficient distance from the last tooth).
  • an end-of-stroke return means such as an electromagnet 39 (see figure 4 ) or a spring 41 ( figure 10 ) to separate between them the finger 30 and the series of stops 31 when the head 1 has returned to its normal angular position of operation.
  • the bar 41 which carries the rack 31 could be made with a double rack : a rack on the upper edge and a rack on the lower edge, for mounting left or right.
  • the electronic control unit 33 controls the motor 8 so that the arm can then again normally move about 90 ° between its horizontal positions of prohibition and vertical free movement.
  • the finger 30 is an elastic blade and the teeth of the rack have a steeper slope on the side of the support of the blade than the other.
  • the finger, marked 43, driven by the rod is a concave comma-shaped ratchet towards the toothless end of the rack and which can mesh with a rack 45 whose teeth have the same slope on both sides.
  • a "double rack” is no longer necessary.
  • wear and noise are lower compared to the blade.
  • the return spring 41, mounted at the rear of the pawl, is a safety end of stroke. The operation of this ratchet assembly 43 / rack 45 corresponds to that of Figures 6 to 8 .
  • the pivoting of the mechanical assembly and arm relative to the vertical axis the support of the latter allows the arm to release the passage being found parallel to the floor without having been damaged and, remaining secured to its mechanical head and therefore in a controlled position, can not hit other equipment around the barrier.
