Definitions

  • This invention relates to an elevator system and, particularly, to a safe method for restoring from an emergency mode to a normal mode in elevators having no machine room.
  • Figure 3 is a sectional view of a conventional elevator system showing the structure thereof.
  • 1 is an elevator car.
  • 2 is a counter weight (CWT).
  • 3 is a compensation chain.
  • 4 is a relief weight.
  • 5 is a hoist, and it is disposed on the top of the hoistway.
  • 6 is a brake releasing apparatus.
  • the elevator car 1 and the CWT 2 described above are connected to either end of the wire rope wound around the hoist 5.
  • the compensation chain 3 is disposed such that the both ends thereof locate separately under the elevator car 1 or the CWT 2.
  • the relief weight 4 is connected to the compensation chain 3 in cases such as necessitating rescues in emergencies, and adjusts the balance between the elevator car 1 weight and the CWT 2.
  • the brake releasing apparatus 6 disposed on the hoist 5 releases the brake of the hoist 5.
  • the brake releasing apparatus 6 of the hoist 5 is operated by remote control at the side of the landing or the like on the uppermost floor.
  • the brake releasing apparatus 6 allows the brake of the hoist 5 to be manually released to cause the elevator car 1 to move upward or downward due to the unbalance between the elevator car 1 weight and the CWT 2.
  • the present invention that has been made to solve the problem described above, has as its object to provide an elevator system in which restoration to a normal driving with the relief weight unintentionally failed to dismount is restrained.
  • an elevator system comprises a hoist disposed on the top portion of a hoistway, a wire rope wound around a traction sheave of the hoist and provided with an elevator car at its one end and a counter weight at the other end, a compensation chain having respective ends fastened to the lower portion of the elevator car and the lower portion of the counter weight, a relief weight connectable to the compensation chain in emergencies for adjusting the balance between the elevator car and the counter weight to cause the elevator car to move, and detecting means for detecting that the relief weight is connected to the compensation chain.
  • the driving of the elevator car may be suspended when said detecting means detects that the relief weight is connected to said compensation chain.
  • the detecting means may comprise a light switch, which detects that the relief weight is connected to the compensation chain when the relief weight interrupts the beam of light between a light emitting section and a light receiving section of the light switch.
  • the detecting means may be disposed at either the lower portion of the elevator car or the lower portion of the counter weight, and the operation of the elevator car is suspended when it detects the load of the relief weight.
  • Figure 1 is a sectional view of an elevator system of Embodiment 1 of the invention showing the structure thereof.
  • FIG. 7 is a light switch or a detecting means that is disposed at the bottom of the hoistway, and detects whether or not something has passed based on the occurrence or not of the interruption of beams of light running between the light emitting section and the light receiving section thereof opposing each other.
  • An attempt to restore to a normal driving with a relief weight 4 remained connected to a compensation chain 3 fails because an omission to remove the relief weight 4 is revealed through the interruption of the beams of light of the light switch 7 by the relief weight 4 connected to the compensation chain 3, and this induces the suspension of the movement of an elevator car 1, thus preventing restoration to a normal driving.
  • FIG. 2 is an enlarged view of an elevator system of Embodiment 2 of the invention showing the composition under the elevator car.
  • 9 is a beam onto which one end of the compensation chain 3 is fastened.
  • One end of the beam 9 is arranged to be rotatable about a pin 8 under the elevator car.
  • 10 is a spring, and it supports the beam 9 at the other end to bear the weight of the compensation chain 3.
  • 11 is a switch, and it restrains the elevator system's normal driving when the beam 9 serving as an operation lever is pulled downward. The operation lever is pulled downward when the spring 10 is compressed under the loads of the compensation chain 3 and the relief weights 4 mounted thereto.
  • the integral components are disposed at the lower portion of the elevator car 1 in this embodiment, such the components may equally be disposed at the lower portion of the CWT 2.
  • an elevator system comprises a hoist disposed on the top portion of a hoistway, a wire rope wound around a traction sheave of the hoist and provided with an elevator car at its one end and a counter weight at the other end, a compensation chain having respective ends fastened to the lower portion of the elevator car and the lower portion of the counter weight, a relief weight connectable to the compensation chain in emergencies for adjusting the balance between the elevator car and the counter weight to cause the elevator car to move, and detecting means for detecting that the relief weight is connected to the compensation chain, so that it is possible to prevent the relief weight from falling down on and hit the elevator machinery and tools to damage them as a consequence of unintentional failure to remove the relief weight when restoring to a normal operation.
  • an elevator system of the invention is used upon providing a safe restoring method from an emergency mode to a normal mode particularly in an elevator having no machine room.
