Abstract

PURPOSE:To provide a double deck elevator which is able to serve for two floors at different levels at the same time with upper and lower cages regardless of difference of the floor height among the floors in a building. CONSTITUTION:When a user of an elevator depresses a hall call button, a call from the button is registered on a hall call register means 2. A computing means 3 which grasps a present operating condition of the elevator, runs the elevator. When the cage comes to the hall in response to the hall call, the user presses a cage call button which delivers a cage call which is registered on a cage call register means 4. When an elevator operating means 5 issues a drive signal, an elevator drive means 6 drives the elevator in accordance with the drive signal. At this time, the elevator is driven so that an upper cage aligns with the floor level of a floor at which the elevator is stopped. The drive means 7 for upper and lower cages aligns the upper cage 14 with a nearest floor level, and controls a distance adjusting means for adjusting the distance between the upper and lower cages. Upon stopping of the elevator, an arrival detecting means 8 detects such a condition that the upper and lower cages precisely have stopped, and doors are opened in accordance with a detection signal therefrom.

[Problem to be solved by the invention] Throughout the building,
It is considered technically difficult to maintain a constant distance between floors, that is, a constant floor height. However, in conventional double deck elevators, the mutual spacing between the upper and lower cars remains fixed. For this reason, on stop floors with different floor heights, one of the cars must be kept on standby with its door closed, resulting in a problem in that transportation capacity is reduced by the amount that cannot be serviced at the same time.

[0004] This invention was made in order to solve the above-mentioned problems, and its purpose is to obtain a double-deck elevator that can service upper and lower cars at the same time even if the heights of each floor are different. do.

The space between the upper car 13 and the upper car 13 is adjustable. In addition, the car frame 17 below the pantograph 16
is equipped with a hydraulic unit 15, a pump 20 to which an electric motor 19 is coupled, and a control panel 22 for starting and stopping the electric motor 19. When the electric motor 19 is rotated by the output of the control panel 22, the pump is activated. 20 pressurizes the hydraulic oil in the hydraulic unit 15 and sends it to the driving jack 18 via a hydraulic pipe 21. Hydraulic unit 15, pantograph 16, drive jack 18, electric motor 19, pump 20 and control panel 22 described here
constitutes the interval adjustment device of the present invention.

FIG. 1 is a block diagram showing a schematic configuration of an elevator control device according to this embodiment. The elevator control device 1 that sends and receives signals necessary for elevator operation includes a hall call registration means 2, a calculation means 3, a car call registration means 4,
It is composed of an elevator operating means 5, an elevator driving means 6, an upper/lower car driving means 7, and a landing detection means 8.

Here, when the elevator user presses and operates the hall call buttons 11a to 11c, these calls are registered in the hall call registration means 2. The calculation means 3 operates the elevator after grasping the current operating state of the elevator and the registration state of the hall call. When the car arrives in response to the hall call, the elevator user gets into the car and presses the car call button. This car call is registered in the car call registration means 4. Then, when the elevator operating means 5 generates a driving signal in accordance with this car call registration, the elevator driving means 6 operates the elevator in accordance with this signal. At this time, the upper car 13 is driven so as to match the floor of the stop floor, and while the car is running, the upper/lower car driving means 7 is operated by an interval adjustment device so as to match the lower car 14 with the nearest floor. control. Subsequently, when the elevator stops, the landing detection means 8 detects that the up-and-down car has stopped correctly, and the door is opened based on the detection signal. In addition, in order to respond to multiple car calls, car call registration means 4 to upper/lower car drive means 7
are operated repeatedly.

FIG. 4 is a circuit diagram showing a specific configuration of this elevator control device. In the figure, an upper car call button 24, a lower car call button 25, and a hall call button 26 (hall call button 11a in FIG.
~11c) are connected to the control power supply bus PC, respectively. The other ends of these upper car call button 24, lower car call button 25, and hall call button 26 are upper car signal lines 24a to 24m and lower car signal lines 25a to 25, respectively.
n and hall call button signal lines 26a to 26y. The operation signals of each of these call buttons are held in an input register 28 provided inside the small computer 27.

Further, an elevator driving control circuit 30 is connected to the small computer 27 through control circuit output signal lines 29a to 29y. Then, in order to output the control signal, the control signal held in the output register 29 provided inside the small computer 27 is sent to the elevator drive control circuit 30.

Furthermore, a hydraulic unit control circuit 31 is connected to the small computer 27 through hydraulic unit control signal lines 29a1 to 29p1. This hydraulic unit control circuit 31 includes hydraulic unit operation signal lines 29a2 to 2.
The hydraulic unit operation circuit 32 is connected through 9p2. As a result, the operation command held in the output register 29 is given to the hydraulic unit control circuit 31, and
The hydraulic unit operation circuit 32 operates according to the control signal of the hydraulic unit control circuit 31 to control the hydraulic unit 15 and the electric motor 19.
will be controlled.

The small computer 27 also includes landing signal output lines 29a3 to 29o3 and landing signal input lines 33a to 33.
A landing detection circuit 33 is connected by r. Therefore, when the landing detection command held in the output register 29 is transmitted to the landing detection circuit 33, the landing detection circuit 33
The landing is detected and the signal is held in the input register 28.

The operation of the elevator control device configured as described above will be explained.

It is assumed that among the hall call buttons 26, a hall call button for consecutive floors is pressed. These call signals are held in the input register 28 of the small computer 27, and a call is registered. Further, various signals necessary for controlling the elevator are also input to the small computer 27. Therefore, the small computer 27 generates an elevator drive signal based on these input signals, and causes the output register 29 to hold this signal. The elevator drive control circuit 30 uses this output register 29.
The elevator is operated according to the elevator drive signal held in the elevator. The elevator is therefore operated to answer the hall call.

Next, when the elevator user who has boarded the car pushes and operates the upper car call button 24 and the lower car call button 25, these call signals are also input to the small computer 27, and the above-mentioned Similarly, registration of these signals, generation of elevator drive signals, and operation of the elevator are performed. At this time, the elevator drive control circuit 30
is controlled to match the floor of the upper car's stopping floor.

On the other hand, an interval control command is sent to the output register 29 in order to align the position of the lower car with the floor below the floor where the upper car stops. Therefore, the hydraulic unit control circuit 31 controls the hydraulic unit operating circuit 32 while the elevator is running. At this time, the electric motor 19 of the hydraulic unit 15 is controlled so as not to impair the riding comfort of the passengers, and the required amount of pressure oil is sent to the drive jack 18. Therefore, the upper car 13 and the lower car 14 land simultaneously on two consecutive floors.

In this way, after the elevator has landed on the floor, when the small computer 27 transmits the completion of the landing control, the landing detection circuit 33 detects the position and gives a signal to the small computer 27 to open and close the door.

Thus, according to this embodiment, of the two cars connected vertically, the upper car is run as a reference, and during the run, the lower car is moved to the floor below it. Since the spacing between the cars is controlled to match, even if the floor heights are different on each floor, the upper and lower cars can be serviced at the same time.

In the above embodiment, the two cars are moved using the upper car as a reference for stopping, but the lower car 14 is fixed to the car frame 17, and the position of the upper car 13 can be adjusted. By doing so, the lower car may be used as a reference while traveling, and the interval between the upper cars may be controlled so that the upper car matches the floor height of the floor above it.

[0021] Furthermore, in the above embodiment, the spacing adjustment device was composed of a hydraulic jack, a pantograph, etc.
The pantograph may be directly driven by an electric motor, and in this case, a linear motor may also be used. Furthermore, the car can be made self-propelled by using a rack and pinion as the car frame and guide device and using an electric motor.

Note that the present invention is also applicable to a configuration in which three or more units are connected vertically.

[0023]

[Effects of the Invention] As is clear from the above explanation, according to the present invention, the distance between one of the two cars connected and driven vertically with respect to the other car is adjusted. and a spacing adjustment device for driving and controlling the elevator so that one car matches the floor of the stop floor, and also controls the drive of the elevator so that the other car matches the floor of the other successive stop floor.
Since the elevator is equipped with an elevator control device that controls the interval adjustment device during travel, even if the distance between floors differs between floors, the upper and lower cars can be serviced at the same time.
