Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an improvement in an elevator operating device.
[0002]
[Prior art]
Conventionally, when an elevator car is stopped between floors due to a power failure or the like (hereinafter referred to as “out of level”), the elevator is operated immediately to the nearest floor (hereinafter referred to as the “nearest floor”) after the restoration of the power failure. Is performed.
[0003]
Also, during elevator maintenance, there are many cases where the elevator car is stopped outside the level and work inside the tower is performed. In this case, when the maintenance operation is switched from maintenance operation to automatic operation, the operation of this elevator is Is done automatically.
[0004]
[Problems to be solved by the invention]
However, in such an automatic recovery operation, the elevator car may be driven toward the terminal floor depending on the situation at that time, and a very dangerous case is expected.
[0005]
That is, the following is the case.
1. The automatic switch is turned on immediately on the elevator car or during or after the pit work.
2. In particular, in the case of an elevator 1 or a hydraulic elevator without a machine room as shown in FIG. 2, the risk is higher because there is almost no gap at the top.
[0006]
The present invention has been made in view of the above points, and an object of the present invention is to provide an elevator operating device that performs an appropriate operation according to a situation.
[0007]
[Means for Solving the Problems]
The present invention relates to a system in which an elevator car is operated toward the nearest floor by operating each of the automatic operation recovery switches installed at different locations in a tower. It determines the driving direction of the car.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
The present invention changes the operation direction of an elevator according to a switch actually operated among a plurality of restoration switches.
[0009]
【Example】
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is an example of a flowchart of the elevator operating device according to the present invention.
[0010]
That is, in step 1, it is first checked whether the automatic operation recovery switch (provided on the car, in the pit, or on the control panel) has changed from OFF to ON, and if it has been turned on, the operation is switched to automatic operation in step 2.
[0011]
Next, in step 3, it is checked whether the elevator car is within the level or outside the level. If the elevator car is within the level, the rescue operation is not performed (step 4).
[0012]
In step 5, it is checked how the operation mode was before restoring the automatic operation. That is, the operation modes to be checked in step 5 are the following four (*).
1 Operation switch is OFF (elevator is stopped)
2 Installation operation 3 Manual operation on car 4 Manual operation in car
If the operation mode before the restoration to the automatic operation is not any of the above, the elevator car performs the rescue operation to the nearest floor. (Step 6)
[0014]
However, if the operation mode is one of the above, the process goes to step 7 to check whether the selector is at the end floor (the top floor or the bottom floor). Of course, you may check whether it is near the end floor.
[0015]
In step 7, if the selector is at the end floor, the elevator car 2 performs rescue operation toward the opposite end floor (toward the center), but if the selector is not at the end floor, rescue operation of the elevator car 2 to the nearest floor. I do. (Step 6)
[0016]
If the above operation is selected, even if the elevator car 2 suddenly starts to move, it is possible to avoid as much as possible the danger of workers on the car or in the pit 3.
[0017]
When starting this rescue operation, it is naturally desirable to give a warning by an alarm or a voice before safety.
[0018]
The direction of the rescue operation may be determined according to a switch for restoring the automatic operation.
That is, it is also possible to determine the switch on the car as the descending direction, the switch in the pit as the ascending direction, or the opposite direction.
[0019]
【The invention's effect】
As described above, according to the present invention, the elevator can always be moved in the safe direction, so that the worst situation can be avoided even if the elevator suddenly starts moving. It is safer if a warning is issued in advance when moving.
