Abstract

PURPOSE:To reduce a difference in a level between cages during side rescue by a method wherein according to a relative distance between the two cages which is outputted from a position comparing device by means of a rescue operation switch, a rescue operation pattern is generated at a rescue elevator. CONSTITUTION:For example, when an elevator B to be rescued is failed in operation and stopped between floors and a rescue operation switch 5 of a rescue elevator A is turned ON, a cage position comparing device 3 determines a relative distance between the two elevators A and B based on a pulse signal from two pulse count devices 2 through a pulse rate converting device 13. According to the relative distance, a rescue operation pattern is generated by a rescue operation pattern generating device 4. A hoist 7 is driven through a driven device 6, and the rescue elevator A is operated to the side position of the elevator B to be rescued. This constitution performs smooth side rescue.

Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to a side rescue operation device for an elevator.

(Prior art) When an elevator stops between floors due to a malfunction or activation of a safety device and becomes unable to run, elevator maintenance is carried out to rescue passengers trapped in the elevator car. The rescuer or rescuer transfers onto the car through the upper hall door,
It is well known that passengers are rescued by opening the car rescue door.

On the other hand, in elevators with express zones such as those in high-rise buildings, if the car becomes unable to run within the express zone, it is impossible for elevator maintenance personnel or rescue personnel to transfer to the top of the car from the upper hall door. Therefore, a side rescue operation device is installed.

This side rescue operation device is a system in which elevator maintenance personnel or rescue personnel operate a horizontally adjacent elevator (hereinafter referred to as the rescue elevator) in the same hoistway as the elevator that has become inoperable (hereinafter referred to as the rescued elevator). Get on board,
By operating an in-car rescue operation switch, the rescue elevator device reads the location of the car that is unable to run and has stopped from the device of the rescued elevator, automatically operates the rescue car towards that position, and automatically stops the car. Passengers are rescued by opening the rescue door on the side of the car.

A conventional example of such an elevator side rescue operation device is the fourth one.
It is shown in the figure. A and B are two adjacent elevators in the same hoistway, and both have exactly the same configuration, and both A and H can be the rescue elevator or the rescued elevator, but here Rescue A, elevator
B will be explained as an elevator to be rescued.

In the figure, 1 is a pulse generator that is attached to a shaft that rotates with the movement of the elevator car, such as the main sheave shaft, motor shaft, governor sheave shaft, tape axle, etc. of the elevator, and generates a number of pulses proportional to the travel distance of the elevator car. It is. 2 is a pulse counting device that creates car position data by counting up the pulses generated by the pulse generator 1 when the elevator is going up and down counting it when it is going down; 3 is the car position data 2 of rescue elevator A;
A car position comparison device 4 creates relative distance data 30 between the two cars by comparing the car position data 20B of the rescued elevator B; 4 is a car position comparison device 3 when the in-car rescue operation switch 5 is operated 6 is a rescue operation pattern generating device that creates a rescue operation pattern 40 for automatically traveling the rescue elevator A to the position of the rescued elevator B and stopping it based on the relative distance data 30 between both cars created by the rescue elevator B; This is an elevator drive device that drives an elevator hoist 7 according to a rescue operation travel pattern 40 created by a pattern generator 4.

In such a conventional elevator side rescue operation device,
The pulse counting device 2 always stores data representing the current position of the car by counting up the pulses generated by the pulse generating device 1 when the car is moving and counting down when the car is going down. Now, if the rescued elevator B stops between floors for some reason and becomes unable to run, the elevator maintenance worker or the rescue worker gets into the rescue elevator A and operates the in-car rescue operation switch 5. A rescue operation begins.

That is, the car position comparison device 3 of the rescue elevator A compares the car position data 20A of its own car with the car position data 20B of the rescued elevator B, and calculates the relative distance data 30 between the two cars to the rescue operation pattern generator 4. Output to.

The rescue operation pattern generator 4 starts a rescue operation toward the rescued elevator B by inputting the relative distance data 30 between the cars, and selects the position where the relative distance between the cars is O, that is, the position of the rescued elevator B. A rescue operation pattern 4o that stops right next to the elevator is output to the elevator drive device 6.

As a result, the rescue elevator A drives to the side of the elevator B to be rescued, and rescues the passengers trapped in the elevator B to be rescued through the rescue opening provided on the side of the car.

(Problems to be Solved by the Invention) However, such conventional elevator side rescue operation devices have the following problems.

That is, the pulse generator 1 is generally attached to a main sheave shaft, a motor shaft, a governor sheave shaft, a tape axle, etc., which rotate as the elevator car moves. FIG. 5 shows an example in which the pulse generator 1 is attached to the governor sheave sleeve, and the governor rope 8 is stretched between the upper and lower governor sheaves 9 and 10, and one part of the governor rope 8 is fixed to the car 11 with a safety link 12. has been done. Then, as the car 11 moves, the governor rope 8 also moves, and as a result, the upper and lower governor sheaves 9 and 10 are rotated. Therefore, a pulse generator 1 is directly connected to the shaft of the upper governor sheave 9, and generates a number of pulses proportional to the moving distance of the car 11.

Here, if the diameter of the governor sheep is the same for both rescue elevator A and rescued elevator B, the same number of pulses should be generated. Therefore, if the position data in the pulse counting devices 2 of both elevators A and H are set to be the same at the lowest floor level, the car position data in the devices should be the same.

However, there is a limit to the precision of the governor sheave construction, and the reality is that there are some errors in the diameter of the governor sheave.As a result, there is a large difference in the diameter of the governor sheave between rescue elevator A and rescued elevator B. If the journey is long, the discrepancy in the car position data becomes large, and even if rescue elevator A reads the car position data of rescued elevator B and performs a rescue operation, a large positional discrepancy will occur between both cars, and a situation where side rescue will not be possible. There were some problems that arose.

In addition, even if the governor sheep of rescue elevator A and rescued elevator B are selected to have relatively well matched sheave diameters when installing the elevator, there is a problem that the sheave diameter error occurs due to aging and the levels at the time of side rescue do not match. There was a point.

This invention was made in view of such conventional problems, and it is possible to perform side rescue by reducing the error in the inter-car level during side rescue without being affected by the installation location of the pulse generator for car position detection. An object of the present invention is to provide an elevator side rescue operation device that can smoothly carry out rescue operations.

[Structure of the Invention] (Means for Solving the Problems) The elevator side rescue operation device of the present invention is attached to the movable part of each elevator in order to detect the car position of both elevators, and calculates the car travel distance. a pulse generator that generates a proportional number of pulses; and a pulse generator that counts the pulses generated by each of the pulse generators;
A pulse counting device that creates car position data for each elevator, and a car position data of the rescued elevator input from the pulse counting device of the rescued elevator, which is converted into the number of pulses per unit traveling distance (pulse rate) of the rescued elevator. A pulse rate conversion device that converts into position data compares the car position data of the rescue elevator with the car position data of the rescued elevator converted into the pulse rate of the rescue elevator by the pulse rate conversion device, and calculates the relative distance between both cars. and a rescue operation pattern generating device that generates a rescue operation pattern in the rescue elevator according to the relative distance between the two cars outputted by the car position comparison device using a rescue operation switch. be.

(Function) Elevator side of this invention. In the side rescue operation device, when the rescued elevator stops between floors and side rescue operation of the rescue elevator is required, the rescue elevator's pulse rate conversion device converts the car position data of the rescued elevator to the rescue elevator's car position data. The data is converted into a pulse rate, and the car position comparison device compares the car position data of the own car from the pulse counting device on the rescue elevator side with the car position data of the rescued elevator, and outputs the relative distance between the two cars.

Then, based on the obtained relative distance, a rescue operation pattern generator on the rescue elevator side determines a rescue operation pattern, and based on the obtained rescue operation pattern, rescue operation is performed to the rescued elevator to perform side rescue.

(Example) Hereinafter, embodiments of the present invention will be explained in detail based on the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention,
Structural elements that are the same as those of the conventional example shown in FIG. 4 are designated with the same reference numerals.

The feature of this embodiment is that a pulse rate conversion device 13 is provided between the pulse counting device 2 and the car position comparison device 3 in each of the rescue elevator A and the rescued elevator B. The number of pulse counts output by the pulse counting device 2 on the highest floor at the same level is calculated as the highest floor car position data 21A. 21B, manually stored in the pulse rate converter 13 of both the own machine and other machines,
Car position data 130 obtained based on pulse rate conversion, which will be described later, is output from each pulse rate conversion device 13 to the car position comparison device 3.

Top floor car position data 21A in each pulse counting device 2. 21B shall be updated every time each elevator A, B reaches the top floor.

Next, the operation of the above-mentioned elevator side rescue operation device will be explained with reference to the flowchart shown in Figure 2.

The pulse counting device 2 of each rescue elevator A1 and rescued elevator B contains current car position data PIA, PI.
B are stored respectively. Also, both elevators A and B
The pulse rate converter 13 includes each elevator A, B.
Every time the car reaches the top floor, the pulse counting device 2 sends the top floor car position data 21A. 21B is read, and the top floor car position data PICA of the elevator A and the top floor car position data PHB of the rescued elevator B are stored (step S1.82).

The top floor car position data PI {A is the car position data detected by the pulse generated by the pulse generator 1 of the rescue elevator A, and the top floor car position data PHB is the pulse generated by the pulse generator 1 of the rescued elevator B. Since the car position data was detected in

Now, in order to rescue the rescue elevator B which has stopped between floors and is unable to run, if the in-car rescue operation switch 5 of the rescue elevator A is operated to start the rescue operation (step S3), the rescue elevator A The car position data PIB of the rescued elevator B is input to the pulse rate converter 13 of the pulse rate converter 13, and the car position data PIB of the rescued elevator B is converted from the pulse rate of the rescued elevator B using the pulse rate of the rescued elevator A using the following equation (1). Position data P 2 B E
It is converted (steps S4, S5).

Next, in the car position comparison device 3, the rescue elevator A
Car position data PIA and car position data P of rescued elevator B converted to the pulse rate of the rescue elevator
2B to calculate the t-th distance data 30 between both cars and provide it to the rescue driving pattern generator 4 (step S6).

Here, since the car position data PIA and P2B are both position data expressed by the pulse rate of rescue elevator A, PIA-P2B is
Position B is the position where the two cars are lined up side by side with their levels aligned.

Therefore, the rescue operation pattern generating device 4 performs a rescue operation by outputting a rescue operation travel pattern 40 to the elevator drive device 6 based on the inter-car relative distance data 30 from the car position comparison device 3. It becomes possible to adjust the level and stop right next to rescued elevator B, and execute side rescue (step S7).
).

In this way, when the rescue elevator A attempts to perform a side rescue operation on the rescue elevator B which has stopped between floors and is unable to travel, the pulse rate of the rescue elevator A causes the difference between the rescue elevator A and the rescue elevator B. Since it becomes possible to control the operation of the rescue elevator by calculating both car position data PIA and P2B, even if there is a difference in the governor sheep diameter or other factors, the pulse generator 1 of both elevators This allows accurate position control of the rescue elevator even when the generated valve slates differ, making it possible to perform side rescue operations smoothly.

FIG. 3 shows another embodiment of the present invention, in which the flowchart of FIG. 2 described above is executed by a microcomputer through software program processing. Therefore, the pulse signal from the pulse generator 1 is given to a pulse counting device constituted by an IC counter 14, which counts up or down depending on the operating direction of the elevator. The IC counter 14 and the microcomputer 15 are connected by a bus line 16, and the pulse count result of the C counter 14 is given to the microcomputer 15 via the bus line 16 and stored as car position data.

A switch signal from the in-car rescue operation switch 5 is input to the microcomputer 15, and a switch signal from the top floor detection switch 17 for detecting that the elevator has landed on the top floor is also input. There is. Further, the microcomputer 15 outputs a rescue operation pattern signal 40 to the elevator drive device 6 in order to drive the four hoists 7 according to the side rescue operation pattern.

Further, the microcomputers 15, 15 of the rescue elevator A and the rescued elevator B are connected by an optical cable 18, so that pulse count data stored in each IC counter 14 can be sent and received.

In the elevator side rescue operation device of this embodiment, the microcomputer 15 operates based on the flowchart shown in FIG. By!
The top floor car position data of the C counter 14 is read and stored (steps SL, S2).

Then, when the rescued elevator B stops between floors and a rescue operation command signal is manually input from the in-car rescue operation switch 5, the side rescue operation is executed by the rescue elevator A (steps 83 to S7).

Here, the exchange of car position data between them is executed by the optical cable 18, and the car position data of the rescued elevator B is converted into the pulse rate of the rescue elevator A side, and the car position data of the rescued elevator B is converted into the pulse rate of the rescue elevator A side. The relative distance is calculated, a rescue operation pattern is created, and the elevator drive device 6 is controlled to perform a side rescue operation.

In the above embodiment, the elevator A on the left side was used as the rescue elevator, and the elevator B on the right side was used as the rescued elevator, but this is not particularly limited. When the vehicle stops for a while and becomes unable to travel, the other operates as in the above embodiment and performs side rescue operation.

Furthermore, even if there are three or more elevators in the same hoistway, side rescue operation can be performed in the same way by having the bottoms of two adjacent elevators be taken as in the above embodiment. I can do it.

[Effects of the Invention] As described above, according to the present invention, when one of the adjacent elevators stops between floors and becomes unable to run, when side rescue operation is performed using a normal elevator, the rescued elevator The car position data is converted to the pulse rate of the rescue elevator, the car position is determined based on the pulse rate of the rescue elevator, the relative distance between both cars is calculated, a side rescue operation pattern is created, and the side of the rescue elevator is calculated. Since the rescue operation is performed, the difference in pulse rate is different from the conventional method where the relative position is determined using the individual position data of the rescued elevator and the rescue elevator to create a side rescue operation pattern. To perform side rescue by accurately stopping the rescue elevator right next to the rescued elevator without causing positional errors.
