Definitions

  • the object of the present invention is both a trigger device for the end positions of an elevator, i.e. for the roof of the car and for the shaft pit, and the operating procedure of the same device to achieve the desired purpose. It is a device designed to protect people who may be both in the pit and in the escape (car roof), against possible accidents, based on a trigger device, which once activated, acts on the wedging system of the elevator, stopping it.
  • the present device is characterized in that the present trigger device, in addition to the purpose for which it is intended, is automatically activated in maintenance operations, as well as in situations of absence of power supply, it not being necessary for the trigger device to be activated manually in certain situations.
  • the present invention is included within the scope of safety systems associated to elevation systems such as elevators and particularly among the means of safety aimed at avoiding a possible crushing of the people who may be in the escape or in the pit.
  • the system disclosed in said patent EP 1174381 cannot be considered an automatic operation safety system; secondly, it does not mention any protection for situations of reduced free height of the elevator pit.
  • the system described does not operate the stopping or wedging mechanism of the elevator by a mechanical connection, when it passes a certain position within the elevator shaft. Furthermore, it does not guarantee its operation at any speed and its adjustment is fairly complex.
  • an object of the present invention is a safety system for elevator shafts, which has an automatic operation in maintenance operations or in the absence of power supply, that said operation acts on the elevator wedging mechanism, where the operation is guaranteed at any speed, and where the position adjustment in the elevator run is very simple and exact.
  • the invention trigger device for the end positions of an elevator consists of a device which, once activated, operates the elevator stopping mechanism by a mechanical connection when the car exceeds a certain position in the shaft.
  • the trigger device is formed by a gear motor and lever assembly which jam the elevator wedging system, specifically on the linkage, to produce the emergency stop and which comprises:
  • the trigger device is integrated in a safety system which also has:
  • the trigger device is positioned so that it can be easily accessed for checks, tests and maintenance, and its handling it totally safe from the pit, car roof or outside the shaft.
  • the trigger device is attached to the guides and is positioned in the place after which it is not desired, for any reason, that the car exceeds said position, applying this criterion both for the escape and for the pit.
  • the trigger device has two basic states, activation or rest, and it is only in the activation position, and after the elevator exceeds a certain point, that the elevator stopping or wedging mechanism is operated, by actuation on the elevator linkage.
  • the trigger device is such that if it acts as run stop in the escape and the elevator is in a position above the device, and the elevator were to move downward and jam the device, this would retract so that the descent is not prevented, but automatically resetting without suffering any damage by said operation.
  • the trigger device is such that:
  • the trigger device has a manual electric resetting device which causes the system to reset and return to normal operations if:
  • the resetting device is formed by an operation button with key and should be positioned in the control box, outside the shaft and only accessible to authorized persons. Whilst the system is being reset, the safety series opens to prevent the normal operation of the elevator.
  • the safety system works in combination with a safety relay so that the operation of the elevator in normal manoeuvre is only possible if the trigger device is at rest and the safety relay is activated.
  • the safety system opens the safety relay and, therefore, the elevator cannot move, in the following conditions:
  • the safety system activates the safety relay in the above conditions only when the inspection manoeuvre is activated in one of them. At the point when the inspection manoeuvre is deactivated, the safety system opens the safety relay and does not return it to its closed state until it acts on the resetting system.
  • the trigger device has a pilot light which is illuminated when the system is active and identifies the locations of said devices.
  • Figure 1 shows a representation of the trigger device which forms part of the safety device object of the invention.
  • Figure 2 shows the same above piece whereon a support piece for wedges has been positioned.
  • the invention of the trigger device for the end positions of an elevator has the purpose of protecting operators when the escape or the pit do not have sufficient dimensions to avoid the operator from being crushed.
  • the trigger device as represented in figure 1 , is integrated within a safety system which, in addition to having the trigger device, has:
  • the trigger device has the necessary elements so that, in active position, it can act on the elevator wedging system causing it to stop, once this exceeds a determined position.
  • the trigger device has a gear motor (7) in charge of deploying a hook, pendulum or lever (1) when it is in active position.
  • Said hook or pendulum (1) acts on the elevator linkage for the wedging thereof.
  • the hook or pendulum (1) is associated to a spin axis (2), which at the opposite end to that of the hook or pendulum (1), has a first crankshaft (3) which transmits the rotation of the gear motor (7).
  • a second crankshaft (4) which indicates the status of the trigger device, so that when the gear motor (7) turns, said second crankshaft (4) acts on the micros (5).
  • the trigger device represented has two springs (8) positioned between two support plates, an upper one (9) and another lower one (10) so that said springs (8) absorb the possible stresses to which the trigger device may be subjected when performing the contact with the elevator linkage.
  • the trigger device also has a third micro (11) associated to the run of the damping system spring which may be connected to the safety series of the elevator.
  • the trigger device has a pilot or light source (13) which is illuminated when the system is active so that it clearly identifies the locations of said devices and their status.
  • All elements of the trigger device are housed in a casing (6) which is conveniently closed, firstly by a support piece (12) ( figure 2 ), and also covered by other guide support plates, which have not been represented.
