Definitions

  • the object of the present invention is an emergency apparatus intended to move the cage of the lift to one of the two nearest landings in case of a failure of the electric power supply.
  • the object of this invention is to use the system of The control board and relative sensors previously installed and utilised in conditions of normal electric power supply to allow to perform all the operations required for the emergency in case of blackout.
  • the installation of the apparatus can be accomplished by means of simple connections between the apparatus itself, the control board of the existing system and the electrical network. Its capacity of making use both of the existing control board and sensor system, makes it possible to avoid complicated and costly installations along the lift shaft, also permitting a remarkable saving in costs and materials.
  • the apparatus comes into operation, supplies the electric control board and the relative sensors thereof, and, making use of the data concerning the functioning of the cage previously stored therein, sends the necessary drive to the control board, for properly controlling the emergency manoeuvre.
  • the apparatus stops working, leaving the lift in the "out of order" condition until the electric power supply is back.
  • figure 1 shows the block diagram of the parts comprised in the emergency apparatus
  • figure 2 shows the flow diagram of the functions, referred to the various situations wherein the blackout can occur.
  • the emergency apparatus for lifts of the invention comprises three principal units:
  • the power module includes a switch/inverter composed of a remote control switch, with the relative control circuits usually on "network” position, which switches the system to the "inverter” position when the emergency manoeuvre starts.
  • a network sensor that transmits the condition of blackout to the interface module in case one or more of the three phases of input line voltage should fail.
  • a battery charger to recharge the battery unit and supply all the circuits inside the apparatus.
  • a section comprising two three-phase inverters, one of which is preferably a 50V/5Hz inverter intended for supplying the motor of the lift, while the other one is a 380V/50Hz inverter intended for feeding the control board and the door opening controls.
  • the interface module by means of input sensors, continuously stores data from the control board, such as the position of the cage and the relative functions thereof.
  • the interface module employs such data to start the emergency manoeuvre, if needed, utilising the control outputs to transmit all the necessary operations to the control board for the "rescue" to be regularly carried out.
  • the battery unit is composed preferably of six sealed lead-acid batteries, preferably of 12V/6.5Ah, necessary to feed the apparatus in case of blackout.
  • the apparatus When the system is working by input power supply, the apparatus is on bypass position, the battery charger is working, and the conditions transmitted to the different sensors are stored moment by moment. In case the blackout occurs when the lift cage is on a floor and the doors are open, no emergency manoeuvre is needed, the apparatus stays on bypass position and the lift goes "out of order" until the power supply is back.
