Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an improvement of an elevator rescue operation device for rescuing passengers of a malfunctioning elevator.

(Prior art) Two elevator cars are placed adjacent to each other, and when one car stops due to a malfunction and a passenger is trapped inside the car, the person operating the other car tries to rescue the other car. be. That is, the rescue car is stopped on the side of the failed car, the rescue doors provided on the side walls facing each other are opened, and a gangboard is hung between these doors to guide the passengers in the failed car into the rescue car and rescue them.

On the other hand, in normal operation equipment that operates in response to a call, the elevator is operated at high speed and then decelerated to ensure landing accuracy when landing at the destination floor. At this time, a landing control means is provided near each floor level for controlling the speed of the elevator to decelerate while following a landing pattern generated according to the distance from the landing level.

(Problem to be Solved by the Invention) In such a rescue operation, when the rescue car stops to the side of the failed car, if the rescue car is near the level of the floor, the car is stopped by the landing control means. As a result, you will be drawn towards the level. If the rescue door is opened at this time and a gangboard is hung during this time, the board will be slanted due to the faulty car being off level, and there is a risk that the person crossing the door may slip and fall.

Of course, it is also possible to perform an inspection operation and move the rescue car to the same position as the faulty car before rescuing the car. However, while this work is carried out, the rescue is delayed, which increases the sense of panic for the passengers trapped in the failed car, and also impairs the rescue operation function of stopping the rescue car at the failed car position.

[Structure of the invention]

(Means and effects for solving the problem) In the elevator rescue operation device of the present invention, a landing pattern is generated that generates a speed pattern near the landing level of each stopped floor according to the distance from the landing level. A plurality of elevators are installed in parallel and are equipped with a landing control means that decelerates the traveling speed of the elevator while following the speed pattern generated by the landing pattern generator, and furthermore, a plurality of these elevators are installed in parallel. When one of the adjacent elevators is out of order, the car of the other elevator is operated to the side of the car of the failed elevator to raise the car floor level of both elevators. a rescue operation means that automatically stops at substantially coincident positions and rescues passengers in the car of the failed elevator by transferring them onto the other elevator car, and during operation by this rescue operation means, the landing control By providing a means for preventing floor landing control by the means, when the car of the failed elevator stops at a position close to the landing level, and another elevator activates a rescue operation device and performs a rescue operation to the car of the failed elevator. To,
To automatically stop the car of the faulty elevator near the floor level without stopping the car of the elevator in rescue operation near the landing level.

(Example) Examples of the present invention will be described below with reference to the drawings.

31 A configuration diagram of an embodiment of the present invention is shown in FIG. In the figure, 1 is a rescue operation pull-back switch provided on the monitoring panel, 2 is a rescue operation running switch provided inside the rescue car, and 3 is a rescue operation pull-back switch 1 that is turned on to return the rescue car to the standard floor. A rescue pull-back control unit 4 is a rescue drive control unit that travels toward the fault when the rescue drive run switch 2 is turned on; 5 is a destination floor that detects the position of the landing destination floor where there is a response call during normal operation. A position detection unit, 6 is a normal running control unit that controls running during normal operation, and 7 is a unit that accurately lands the car at a level position when the car decelerates toward the destination floor and reaches near the destination floor level. A landing control unit 8 is a motor operating unit that controls the rotational direction and rotational speed of the electric motor according to an upward or downward driving command from the travel control unit 4 or 6 and a driving command from the landing control unit 7. The control unit 9 is an electric motor.

Next, the operation of this embodiment will be explained.

During normal operation, the destination floor position detection section 5 detects the next call to be answered from among the registered calls, and further detects the level position of the destination floor where the response is to land.

Upon receiving this destination floor position data, the normal running control section 6 outputs a driving command and an acceleration/deceleration command to the motor operation control section 8. Further, the normal running control section 6 outputs a landing control command to the landing control section 7 when the car approaches the landing level position. When the landing control unit 7 inputs the landing control command, if the car is shifted upward from the level position, it issues a driving command downward;
If it deviates downward from the level position, the operation command is output upward, and if it deviates upward, it outputs the operation command downward.

The motor operation control section 8 combines the operation command from the normal running control section 6 and the operation command from the floor landing control section 7, and controls the rotation direction and rotation speed of the electric motor 9.

Next, suppose that a failure occurs and a rescue operation is performed to rescue a car adjacent to this car.

When the rescue operation pull-back switch on the monitoring panel is turned on, the rescue pull-back control section 3 pulls the car back to the standard floor in the normal running mode described above. When the car has returned to the reference floor, the rescue pull-back control section 3 outputs a rescue run permission command to the rescue run control section 4, and at the same time outputs a normal run prohibition command to the normal run control section 6. A pullback sequence flowchart by the rescue pullback control unit 3 is shown in FIG. As a result, from now on, the rescue travel control section 4 will issue a driving command to the motor operation control section 8.

FIG. 3 shows a rescue drive sequence flowchart by the rescue drive control section 4. Turn on the rescue operation switch in the car and keep pressing the car door close button to close the door.
The car moves at low speed to the same position on the side of the failure corner.

During rescue driving, landing control during normal driving is not performed, so in order to accurately stop at the stop position near the failure point,
Turn off the operation command a little before the stop position of the failure corner. When the operation command is turned off, the electric motor stops and the brake is applied, but due to the penetrating nature of the car, the car advances a little in the direction of travel before stopping.

The stopping position of the faulty car may be corrected in advance by taking into account the distance from turning off this operation command until the car stops.

After this, the rescue door of the car is opened and the person trapped in the faulty corner is guided into the rescue car. When the rescue operation run switch 2 in the car is turned off, the car returns to the standard floor by rescue pullback control. being pulled back.

〔Effect of the invention〕

As explained above, according to the elevator rescue operation device of the present invention, when a rescue car adjacent to a faulty car is driven to the side of the faulty car, landing control is not performed while the rescue car is operating, and the rescue operation is unique. Since the running control is now performed, even if the faulty car is stopped near the floor level, the rescue basket will not be pulled to the level position and will always automatically stop at the same position as the faulty car. be able to.
