Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a double deck elevator inter-floor length measuring system for measuring the dimension between floors where upper and lower cabs are landed in a double deck elevator having two cabs arranged vertically.
[0002]
[Prior art]
In conventional double-deck elevators, there are many cases in which the dimension between the arbitrary stop floor and the upper or lower stop floor is constant, and the dimension between the upper car and the lower car is also constant. Means for controlling the dimensions between the cabs were not considered.
[0003]
[Problems to be solved by the invention]
However, in double deck elevators that are installed in buildings with uneven floor dimensions that have recently appeared, the dimensions between the upper and lower cabs change because the dimensions between the upper and lower cabs change. It is necessary to adjust the dimension between the upper and lower cabs when the cab is stopped.
[0004]
As a means for this, it is possible to use a car frame position detection device to measure the dimension of the floor length. However, in the position detection information obtained from the lift distance of the car frame, the upper and lower car chambers are calculated from the length of the distance. In this case, sufficient resolution accuracy cannot be obtained.
[0005]
A method of increasing the resolution of the position information obtained from the car frame position detection device is also conceivable. In that case, however, the amount of information obtained from the position detection device is large due to the length of the raising / lowering distance of the car frame. End up.
[0006]
Therefore, an object of the present invention is to provide a double deck elevator capable of measuring a dimension between floors necessary for floor stop control by a more accurate measurement method.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0014]
(First embodiment)
A double deck elevator according to a first embodiment of the present invention will be described with reference to FIG.
[0015]
The double deck elevator of this embodiment is installed in, for example, a building with uneven floor dimensions, and as shown in the figure, an upper car 2 and a lower car 3 are mounted on an outer car frame 1 and an upper car 2 A car room driving device 5 is provided on one or both of the lower car 3 and the lower car 3. The cab driving device 5 is provided with, for example, a shaft that is threaded in the opposite direction up and down, and is rotated with the upper cab 2 by rotating the shaft under control from a cab position control device (not shown). The lower car 3 is configured to simultaneously move the same distance in the opposite direction (that is, when the upper car 2 is in the upper direction, the lower car 3 is in the lower direction). Reference numeral 6 denotes a hoisting machine that moves up and down the outer car frame 1 on which two upper and lower car rooms 2 and 3 are mounted, and 7 denotes a hoisting machine control device that controls the hoisting machine 6 to control the speed of the outer car frame 1. It is.
[0016]
When measuring the length between the floors, the outer car frame 1 is moved in the upward direction from the lowermost floor or in the downward direction from the uppermost floor. The outer car frame position detecting device 4 travels while measuring the raising / lowering distance of the outer car frame 1 in the hoistway, and the outer car frame landing position detecting device 8 has the upper car 2 and the lower car 3 having a floor length. The position where landing is possible is detected by control, and the outer car frame 1 is stopped when the landing position is reached.
[0017]
Then, the direction in which the upper and lower cars 2 and 3 are separated from the state in which the dimension between the upper and lower cars 2 and 3 is the narrowest, or the direction in which the upper and lower cars 2 and 3 are approached from the state in which the dimension between the upper and lower cars 2 and 3 is expanded most. Then, the car room is moved within the outer car frame 1 under the control of the car room driving device 5. The upper and lower cars 2 and 3 moving in the outer car frame 1 are provided by an upper car landing position detecting device 9 and a lower car landing position detecting device 10 respectively installed in the upper car 2 or the lower car 3. Detects the car landing position (position where the door can be opened and closed). When both the upper car 2 and the lower car 3 detect the landing positions, the upper and lower cars 2 and 3 are moved between the upper and lower cars 2 and 3 by the upper and lower car length measuring device 11 based on the movement distances until the respective landing positions are detected. Measure the floor length.
[0018]
For example, when the dimension between the upper and lower cars 2 and 3 is the narrowest floor dimension A, and the upper and lower cars 2 and 3 are moved a in the upward and downward directions, the upper car 2 detects the landing position. Then, the upper and lower cars 2 and 3 are further moved in the upward and downward directions, and when the lower car 3 detects the landing position when moved b from the initial position (the narrowest position), the floor length Can be measured as (A + a + b). In addition, the floor length dimension with the dimension between the upper and lower cars 2 and 3 being widest is B, and when the upper and lower cars 2 and 3 are moved by c in the direction of narrowing the car, the upper car 2 becomes the landing position. Then, when the upper and lower cars 2 and 3 are further moved in a direction to narrow the distance between the cars and moved from the initial position (the position in the most expanded state) d, the lower car 3 detects the landing position. The floor length can be measured as (Bcd).
[0019]
In the above description, the car room driving device 5 is configured to move both the upper and lower car rooms 2 and 3 at the same time. However, the car rooms may be sequentially moved one by one. Furthermore, when the outer car frame 1 is stopped between the floors, if one of the upper and lower cars 2 and 3 can be accurately stopped at the landing position, the car room driving device 5 can It is also possible to measure the length between floors by moving only the car room.
[0020]
As described above, the double-deck elevator according to the present embodiment adjusts the stop position of the upper car 2 and the lower car 3 to the landing position according to the actual building, and the outer car frame landing position detection device 8. When the outer car frame 1 is stopped between the floors using the, and the relative distance between the upper and lower cars 2 and 3 is changed by the car room driving device 5, and the landing positions of the cars 2 and 3 are detected. A floor length measuring system having a floor length measuring function for measuring the length of the floor from the information on the stop positions of the cars 2 and 3 is provided.
[0021]
Accordingly, it is possible to measure the dimension of the floor length with high accuracy that matches the actual building configuration.
[0022]
(Second Embodiment)
Next, a double deck elevator according to a second embodiment of the present invention will be described with reference to FIG.
[0023]
In this embodiment, the hoisting machine control device 7 is provided with a memory device that can set an arbitrary value, and information on the floor to be measured is set from the control device operating means 12 to the set information. Based on this, it is configured to measure an arbitrary floor length to be measured.
[0024]
That is, in this embodiment, information on the floor to be measured is input by the hoisting machine control device operating means 12 connected to the hoisting machine control device 7, and this information is input to the hoisting machine control device 7. Set to the provided memory device. Then, the hoisting machine control device 7 moves the outer car frame 1 according to the information between the floors to be measured set in the memory device, and the outer car frame landing position detecting device 8 is moved between the floors to be measured. The position where the upper car 2 and the lower car 3 can land by floor length control is detected, and the outer car frame 1 is stopped when it comes to the landing position.
[0025]
Then, similarly to the control in the first embodiment, the upper and lower cars 2 and 3 are moved in the outer car frame 1 and the car is placed by the upper car landing position detection device 9 and the lower car landing position detection device 10. The floor position is detected, and the floor length between the upper and lower cars 2 and 3 is measured by the upper and lower car length measuring device 11 from the movement distances of the upper and lower cars 2 and 3 to the respective car landing positions.
[0026]
Therefore, it is possible to measure the dimension of the inter-floor length with high accuracy that matches the actual building configuration for the inter-floor length dimension of an arbitrary floor to be measured.
[0027]
(Third embodiment)
Next, a double deck elevator floor length measuring system according to a third embodiment of the present invention will be described with reference to FIG.
[0028]
In this embodiment, the hoisting machine control device 7 is provided with a memory device that stores information on the length of the floor, and information on the length of the floor is stored in advance in this memory device. Then, when the inter-story length is longer than the moving distance of the upper and lower cars 2 and 3 in the outer car frame 1 and the dimension measurement between the upper and lower cars 2 and 3 is impossible by the control as in the first embodiment, The measurement by the control as in the first embodiment is not performed, and the length between the floors stored in advance in the memory device is used instead.
[0029]
That is, in the first embodiment, when the floor length is longer than the moving distance of the upper and lower cars 2 and 3 in the outer car frame 1 (for example, when the middle 5th floor and the sixth floor are floors that do not stop, Dimension measurement between the upper and lower cars 2, 3 becomes impossible.
[0030]
Therefore, in this embodiment, information on the length of the floor is stored in advance in a memory device provided in the hoisting machine control device 7, and the length of the floor exceeds the car movable range in the car frame. In this case, the floor length measurement function by the movement between the upper and lower cars 2 and 3 in the first embodiment is cut off, and the floor length information stored in advance in the memory device of the hoisting machine control device 7 is used.
[0031]
Therefore, when the floor dimension to be measured exceeds the movable range of the upper and lower cars in the outer car frame 1, the floor length measuring function for measuring from the dimension between the upper and lower cars is separated, and the floor previously stored in the memory device is separated. Inter-length information can be substituted.
[0032]
【The invention's effect】
As described above, according to the present invention, for example, in a double deck elevator installed in a building having different dimensions between floors, the dimensions between upper and lower cabs required for landing control on the stop floor can be measured. . In addition, the distance to which the upper and lower cabs move up and down relative to the car frame is much shorter than the length of the car frame, so the dimensional measurement resolution is greatly improved. It is possible to carry out with less accuracy.
