Abstract

PURPOSE:To prevent the automatic closure of a door and permit the easy opening even if a door is automatically closed by preventing the operation of a cage and controlling the operation of a cage door by the electric power when an operation stop switch is operated, while by opening the cage door when a getting-on field button on the stop floor of the cage is operated. CONSTITUTION:When an operation stop switch 2A is cut off, a cage is held in stop state on a floor where the operation stop switch 2A is cut off by the operation of an operation instruction circuit 1A, and a cage door is kept in stop at the position at the time point when the operation stop switch 2A is cut off. In this case, a door stop switch 28 is in turned-ON state, and electric power is not cut off, and since a door opening/closing circuit 3 is connected with a door opening/closing instruction circuit 1B, the closure of a getting-on field door by the mechanical force is prevented. Further, even if the cage door is closed by hands or automatically closed by the mechanical power due to the generation of electric failure, the operation stop switch 2A becomes nonsensitive, since a cage position relay contact point 5 is closed, if a getting-on field button 6 on the stop floor is pushed when an electric power source operates, and the door can be opened through the electric action, and the generation of a use disabled state is prevented.

The conventional 1-A stop device of an elevator has a 2-part structure, and when the car is stopped on a floor, when the caretaker enters the car and shuts off the operation stop switch (2A), the operation command circuit ( The operation command for IA) is also cut off, and the car is no longer operable. At the same time, the door body switch (2B) is also cut off, and the car door opening/closing command is also cut off, or an electric braking force is generated, resulting in a state of almost zero speed. In this way, the manager suspends the elevators at night.

The elevator landing door opens and closes by engaging with the car door.
For safety reasons, it is mandatory to provide a mechanical self-closing device, and even if the car door is engaged, if the electric power is cut off, the car door will close using the self-closing force described above. Once the door is closed, the locking device for the landing door is activated and the door cannot be opened from the landing side. That is,
It becomes unusable. In order to prevent this, if the car door is near the fully open position, a spring or other mechanism is used to mechanically generate the door opening force, or the worm and the play rate between the worm gear are used to prevent the car door from closing automatically. Equipment is installed.

In addition, when the car door is fully closed, it is often necessary to have a mechanical force to keep the car door closed, so when the car door is close to fully open, a mechanical force is required to close the car door. If you leave the door half-closed, the door will close automatically and become unusable. For this reason, electrical braking force is applied to prevent self-closing.

[Problem to be solved by the invention] In the conventional elevator door stop device as described above,
Since the door is prevented from closing automatically by using spring force, the idle rate of gears, or by adding electrical braking force, in the former case, a non-linear load force acts when the door is closed electrically. There is a problem in that not only does it have an adverse effect on the door opening/closing performance, but it also becomes impossible to keep the door open due to changes over time, which needs to be corrected during maintenance. Furthermore, in the latter case, self-closing cannot be avoided in the event of a power outage, and there is a problem in that the landing door is locked and cannot be opened.

While the car is stopped on the floor, if a caretaker enters the car and shuts off the operation suspension switch (2A), the operation command circuit (IA) will operate and the car will turn off the operation suspension switch (2A). ) remains stopped on the floor where it was shut off, and the car door remains stopped at the position it was in when the operation stop switch (2A) was shut off. That is, if the car door is fully open, it is maintained in the fully open state, and if it is in the middle of opening or closing, an electric braking force is applied from the position when the operation stop switch (2A) is shut off, and the car door is stopped at that position. At this time, the door switch (2B) is turned on, the electric power is not cut off, and the door opening/closing circuit (3) is connected to the door opening/closing command circuit (1B).
Since it is connected to the landing door, it will not close due to the mechanical self-closing force of the landing door.

In addition, even if the janitor closes the door manually, or if the door closes automatically due to a power outage, when the power is restored, you can press the landing button (6) on the floor where the door stops. Ba,
At this time, since the car position relay contact (5) is closed, the operation stop switch (2A) becomes insensitive and the door opens electrically, so the car does not become unusable.

[Effects of the Invention] As explained below, in this invention, when the operation stop switch is operated, the operation of the car is disabled, the movement of the car door is controlled by electric power, and the operation of the car is stopped when the car is stopped. The car door opens when the floor landing button is operated, so the electric power that controls the car door is not cut off, and the mechanical self-closing force prevents the car door from closing. Even if the door closes automatically, it can be opened electrically, which has the effect of preventing the door from becoming unusable.
