Definitions

  • This invention relates to a tilting alarm system for a mobile machine having a prime mover and an articulated component such as a vibratory compaction roller.
  • a typical smooth drum, single drum vibratory roller consists of a prime mover having a forwardly mounted vibratory drum roller which is supported by a frame with its axis of rotation transverse to the direction of movement of the prime mover.
  • the drum frame is pivotally mounted on the prime mover to allow limited pivotal movement of the frame about the axis of movement of the prime mover.
  • the pendulum switch may be mounted at or near the articulation point of the roller.
  • a tilting alarm system for a machine having a prime mover and an articulated roller
  • the alarm system comprising a pendulum switch adapted to sense the transverse tilt angle of the roller with respect to the prime mover and an audible and/or visual alarm adapted to be activated by the pendulum switch when the tilt angle exceeds a predetermined value.
  • the roller is a vibratory roller and the tilt alarm system includes a vibration interrupter relay which de-energises the vibratory system when the tilt angle exceeds a second predetermined value that is larger than the first predetermined value.
  • both the audible and/or visual alarm as well as the vibration interrupter relay are connected to adjustable time delays to allow for short bumps and sways.
  • Fig. 1 is a schematic diagram of a tilting alarm system according to one embodiment of the invention. MODES FOR CARRYING OUT THE INVENTION
  • the tilting alarm system 10 of one embodiment of the invention includes a level pendulum switch 11 having outwardly directed arms 12 and 13 each of which has inwardly directed operating fingers 14 and 15 respectively.
  • the pendulum switch 11 is pivotally mounted about axis 16. When the pendulum switch 11 is in its normal or neutral position as shown in Fig. 1 where the roller (not shown) is not tilted, the operating fingers 14 and 15 are clear of inductive pick ups 17 and 18 respectively.
  • the inductive pick ups 17 and 18 are electrically connected to a maximum oscillation variable timer relay 19 which in turn is connected to an alarm and warning light relay 20 that is adapted to energise the warning light 21 and/or the audible alarm 22.
  • a central inductive pick up 23 which operates the vibration interrupt circuit.
  • the central pick up 23 is electrically connected to the vibration cut-out variable timer relay 24 which in turn is connected to the vibration interrupt relay 25.
  • the pendulum switch 11 is mounted at the articulation point of the vibratory roller to sense the transverse tilt angle of the front section of the vibratory roller.
  • the angle of tilt is sensed in two stages. In the first stage, a tilt angle between 5° to 15° (depending on the model of the roller) activates the audible alarm 22 and the warning light 21 mounted adjacent the operator to warn the operator that the front of the roller has reached a dangerous tilt angle. In the second stage, when the tilt angle is between 5° to 15° (depending on the model of roller), the vibration interrupt relay 24 (which is wired into the roller vibration circuit) shuts down the vibration mechanism of the roller reducing the slide effect of the slope to further warn the operator of a critical tilt angle.

Abstract

La présente invention concerne un système d'alarme d'inclinaison (10) pour une machine ayant un élément amovible principal et un composant articulé comme un rouleau, qui comprend un commutateur de pendule (11) pouvant capter l'angle d'inclinaison transversal du rouleau par rapport au système amovible principal et/ou une alarme visuelle (20, 21, 22) pouvant être activée par le commutateur de pendule lorsque l'angle d'inclinaison dépasse une valeur prédéterminée.
