Description

Technology field

  The present invention relates to an elevator apparatus in which a plurality of large and small cages are installed in a single elevator of a high-rise building, and each of the cages is operated independently.

  Previously, a single elevator was used to install multiple cages of the same cube.

For this improvement, each single elevator has storage pits at the uppermost position and the lowermost position, so it is safe and secure for periodic inspections and storage at the time of failure. Provide an elevator apparatus that can save money by doubling the effective use area of a single elevator by economically operating each car and simultaneously operating both cars.
JP 2006-176286 A

  In the prior art, since both the raising and lowering baskets have the same area, the center of the hoisting and hoisting machine is at the same position, so that the machine is complicated and has a safety problem.

  In order to achieve the above object, according to the present invention, in claim 1, the elevator apparatus for raising and lowering a plurality of baskets in the same hoistway (1), wherein the lower car (2) is lowered to the lowest position. The upper cage (3) is accommodated in the upper pit (9) when it rises to the top, and the hoistway (1) is accommodated in the lower pit (8). ) In the lower cage (2) and the upper cage (3) have the same shape and size on the landing (12, 13) side, and the depth area of the upper cage (3) is the hoistway of the lower cage (2) (1) It is installed in the rope (6) provided in the inner center, and the lower cage (2) is driven by the driving force of the hoisting machine (4) provided above by the rope (6), This rope (6) passes from the hoisting machine (4) through the deflecting wheel (14) to the back side of the lower car (2). The counterweight (10) provided between the walls is arranged so that it can be raised and lowered, while the upper cage (3) is driven by the driving force of the hoisting machine (5) provided above by the rope (7). When driven, the rope (7) passes from the hoisting machine (5) to the deflector wheel (15) and passes between the right side or left side of the upper car (3) and the right side or left side of the upper car (3). A counterweight elevator (11) provided on the vehicle is arranged so that it can be moved up and down.

  The double-car elevator device of the present invention is provided with a car storage pit at the uppermost and lowermost parts in a single elevator, so that the passengers and inspectors are safe and secure to store the car in the pits at the time of regular inspection and failure. Yes, it is possible to double the effective use area of a single elevator by economically operating both large and small cages and operating both baskets simultaneously in accordance with a small time zone with a large ascending and descending population. Because both cages are the same cube, the hoisting and hoisting machine ropes are concentrated in the center, and there is a problem that the ropes are complicated and may need to be stopped simultaneously at the time of inspection. There are area utilization and safety advantages.

  The double-car elevator device is an elevator device that raises and lowers a plurality of small and large cars in the same hoistway, and the lower car (2) is stored in the lower pit (8) when it is lowered to the bottom. The upper car (3) is adapted to be housed in the upper pit (9) when it rises to the top, and the shape and size of the upper car and the lower car on the landing side in the hoistway. However, the area of the upper cage is about half that of the lower cage.

FIG. 1 shows an elevator apparatus that raises and lowers a plurality of baskets in the same hoistway (1). The lower car (2) is housed in the lower pit (8), while the upper car (3) The upper pit (9) is housed in the hoistway (1), and the upper cage (3) on the landing entrance (13) side and the lower cage (2) on the landing entrance (12) side. The shape and size are the same, and the depth area of the upper cage (3) is installed in the rope (6) provided in the center of the hoistway (1) of the lower cage (2). 2) is driven by the driving force of the hoisting machine (4) provided above by the rope (6), and this rope (6) passes from the hoisting machine (4) through the deflecting wheel (14) to the lower car. It is arranged so that the counterweight (10) provided between the back side and the back wall side of (2) can be raised and lowered On the other hand, the upper cage (3) is driven by the driving force of the hoisting machine (5) provided above by the rope (7), and this rope (7) passes from the hoisting machine (5) through the deflector (15). The cross section of the double-car elevator device characterized in that the counterweight (11) provided between the upper car (3) on the right side of the upper car (3) and the right wall is arranged so as to be able to move up and down. FIG.
FIG. 2 shows an elevator apparatus that raises and lowers a plurality of cages in the same three-dimensional hoistway (1) as viewed from the front of FIG. 1, and is a landing for the upper car (3) in the hoistway (1). The shape of the door (17) side and the size of the lower car (2) on the landing door (16) side are the same, and the depth area of the upper car (3) is the center in the hoistway (1) of the lower car (2). The lower cage (2) is driven by the driving force of the hoisting machine (4) provided above by the rope (6), and is installed in the rope (6) provided in the section. Is arranged so that the counterweight (10) provided between the back side and the back wall side of the lower car (2) can be moved up and down from the hoisting machine (4) through the deflecting wheel (14), On the other hand, the upper basket (3) is driven by the driving force of the hoisting machine (5) provided above by the rope (7), The rope (7) from the hoisting machine (5) passes through the deflecting wheel (15) and is a counterweight (11) provided between the right side surface of the upper cage (3) and the right side wall of the upper cage (3). It is a front three-dimensional view arrange | positioned so that can raise / lower.
FIG. 3 shows that there are four elevator devices for raising and lowering a plurality of cages in the same hoistway (1), and the elevator (1-1) has a lower cage (2-1) carrying people to the top floor and stopping. The elevator (1-2) is in a state where the upper cage (3-2) carries and stops people to the lowest basement floor, and then the lower cage of the elevator (1-3) is large. (2-3) If there are fewer passengers on the 15th floor, the upper car (3-4) of the elevator (1-4) waits on the 15th floor by computer control, and the lower car (2-3) It is a figure which waits for a passenger to transfer to an upper cage (3-4), and is a sectional view of an elevator which raises and lowers faster and efficiently.
FIG. 4 shows that a command board (18) having a digital display (19) installed under each floor display board (20) is provided next to the hall entrance (13), and the command board (18) is controlled by computer control. It is a front view of the command board (18) which can reserve the absence (elderly person, a physically handicapped person) of the presence or absence of transfer by how many people get on and off the floor.

  As an application example of the present invention, there is a commercial space in the lower part of a high-rise building, the upper part is adapted to the conditions of offices and apartments, and when entering or leaving the building Elevator system that is safe and quick and stress-free by computer control of rational lifting and lowering to concentrate. On the other hand, for high-rise buildings, there is no waiting time for group and individual customers in popular high-rise viewing space and viewing restaurant An elegant elevator system that can be accessed directly.

These are sectional views seen from the left lateral front of the double basket elevator device. These are the three-dimensional figures seen from the front right diagonal cross of a double cage elevator apparatus. These are general computer devices of each double cage elevator device, and are diagrams seen from the front for more rational getting on and off. FIG. 2 is a front view of a computer control command panel for conveniently getting on and off the double-car elevator device.
