Description

  The present invention relates to an elevator system, and more particularly to an elevator system suitable for installation in a high-rise building.

  In order to improve the efficiency of elevator operation in high-rise buildings, a method of operating by restricting the stop floor of the elevator is used. An example of such an elevator is described in Patent Document 1. In the elevator system described in this publication, the floor of a building is divided into a plurality of blocks, and each block is provided with an elevator for stopping on each floor that moves up and down only within the block. At the same time, an express elevator is provided for communication to each block.

  Another example of an elevator for a high-rise building is described in Patent Document 2. In this publication, the so-called zoning method and the sky lobby method are combined to increase the efficiency of elevator operation. Here, in the zoning method, the vehicle does not stop from a reference floor (basement) to a specific block, and then stops on each floor in the block. The sky lobby method is a zoning method in which an intermediate floor is a reference floor, and the intermediate floor serving as the reference floor is referred to as a sky lobby.

  In the elevator system described in Patent Document 1, since only passengers whose floors are substantially the same are mounted, there are few stops on the middle floor and passengers' irritability can be reduced. However, an express elevator and a stop elevator for each floor are required for each zone, and the occupied area of the hoistway increases.

  In the elevator system described in Patent Document 2, since the space and speed of the express section of the local elevator can be reduced, the elevator occupation area, facility cost, and running cost of the entire building can be reduced. However, it is necessary for the shuttle elevator to carry all passengers other than the passengers using the zoning elevator whose base floor is the base floor, and the load of the shuttle elevator increases. In order to cope with this load and reduce the waiting time of the user, the number of shuttle elevators may be increased. However, as the number of elevators increases, the area occupied by the elevators increases.

  The present invention has been made in view of the above-described problems of the prior art, and an object of the present invention is to ensure a high transportation capacity without increasing the elevator occupation area in an elevator system mainly installed in a high-rise building.

  In order to achieve the above object, the present invention is characterized in that an elevator system includes a plurality of local elevators that operate only between predetermined floors, and an express elevator that services only predetermined floors. The local elevator is a multi-car elevator or a twin car elevator in which a plurality of cars are arranged in the same hoistway.

  And in this feature, the express elevator should be serviced at the floors at both ends of the service section of the local elevator, and the plurality of local elevators should include those whose service sections do not overlap except for the floors at both ends. . The express elevator may be a double-deck elevator with a two-story passenger car. The express elevators are equipped with a plurality of express elevators, and the service floors of the plurality of express elevators are different from each other except the standard floor. It may be. Furthermore, the local elevator may be a multi-car elevator in which a plurality of cars are arranged in the same hoistway.

  In addition, in the above feature, the multi-car elevator is a slewing circulation type multi-car with two passenger cars connected by a rope, and the service floor of the express elevator is the intermediate floor of the multi-car elevator, and this multi-car elevator The service section may be an odd number of floors, the express elevator is a double-deck elevator with a two-storied car, and the local elevator is a slewing circulation type multi-wheeler with two cars connected by a rope The service floor of the express elevator may be an intermediate floor of the service floor of the local elevator, and the service section of the local elevator may be an even floor.

  Furthermore, the express elevator may be a double-deck elevator with a two-story passenger car, and the local elevator may be a twin-car elevator with two passenger cars arranged in the same hoistway. The floor includes the first and second floors that are continuous up and down, and the service floor of one of the twin car elevators is the second floor including the first floor of the service floor that is continuous above and below the double deck elevator. The service floor of the other car of the twin car elevator may not include the first floor, but may include the second floor of the service floor that is continuous above and below the double deck elevator.

  Another feature of the present invention that achieves the above object includes an express elevator that serves only a predetermined floor and a plurality of local elevators that serve between the predetermined floors, and the service floor of the express elevator is at least local. One of the upper and lower floors of the elevator and the intermediate floor of the local elevator, and multiple local elevators are arranged for each zone set in the height direction of the building where the local elevator is located, the top zone and the bottom zone The number of service floors of local elevators arranged in at least one of the zones is made smaller than the number of service floors of local elevators arranged in other zones.

  According to the present invention, an elevator system mainly installed in a high-rise building is provided with an express elevator and a plurality of local elevators, and each local elevator has a structure in which a plurality of passenger cars are arranged in the same hoistway, so that there are few A high transportation capacity can be secured by the area occupied by the elevator.

  Several embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a schematic configuration of various elevators. It is assumed that the hoistway 11 has such a size that the two cars 10 can move up and down in parallel. In the normal elevator shown in FIG. 1A, a hoistway 11 is assigned to each car 10, and each car 10 can move independently within each hoistway 11. In the double deck elevator shown in FIG. 1 (b), a hoistway 11 is assigned in units of a car 12 connected up and down, and the car 12 having a two-story upper and lower structure is independent in each hoistway. And can be moved.

  In the twin-car elevator shown in FIG. 1C, two cars 10, 10 that can be operated independently from each other are arranged in one hoistway 11. Of course, in this case, the two cars 10 and 10 are operated after preventing collision of the two cars 10 and 10 in the same hoistway 11. FIG. 1 (d) shows a circulating multi-car elevator. In the circulation type multicar type elevator, a pair of passenger cars 1A, 1B; 2A, 2B; 3A, 3B are connected by a rope, and two hoistways 11, 11 are connected to each other. Is circulated in one direction. In FIG. 1 (d), three pairs of cars 1 </ b> A to 3 </ b> B are disposed in the hoistway 13 at intervals.

  In each of the elevator systems (a) to (d) configured as described above, the transportation capacity and the occupied floor area per car are different. In the double deck elevator, the number of passengers is larger than the area of the hoistway 11 because the number of cars in the same hoistway 11 is twice that of the normal elevator. However, if the car 10u located on the upper side stops for getting on and off, the car 10d located on the lower side must also be stopped. Further, the car 10u cannot move to the lowest floor because the car 10d is below, while the car 10d cannot move to the top floor because there is the car 10u above.

  Therefore, in order to move from the lowest floor to the top floor of the building, it is necessary to use escalators, stairs, or other elevators for at least one floor. As a result, the user cannot forbid the inconvenience. However, since a large amount of personnel can be transported at one time, it is suitable for piston transportation between specific two floors. In this case, for example, a person going to the 10th floor gets in from the first floor, and a person going to the 11th floor gets in from the second floor.

  Thus, when the piston is transported between two points and does not stop on the middle floor, the own car is not stopped due to the influence of other cars, and passengers are less frustrated. Therefore, the double deck elevator is suitable for shuttle use. At the same time, when combined with a multi-car elevator or twin-car elevator, unnecessary waiting time at the time of connection is reduced and operational efficiency is increased.

Twin car type elevators have almost the same performance as double deck elevators. However, since two independent cars 10 can be moved up and down in one hoistway 11, if the car dispatch method and service floor are devised, the car 10 can be stopped more wastefully than a double deck elevator. And stoppage can be prevented, and transportation capacity can be increased.

  In the circulating multi-car elevator in which a plurality of passenger cars 1A,... Are arranged in one large hoistway 13, direction reversing portions are provided at the uppermost part and the lowermost part. This circulating multi-car elevator is a skate type in which a pair of passenger cars 1A, 1B,... Are connected by a rope and requires twice as much hoistway area. The number of cars can be increased by 3 to 4 times as compared with the case of a normal elevator. Therefore, a transportation force several times that of a normal elevator can be secured, and as a result, the ratio of the area occupied by the elevator to the transportation force decreases. Further, since the plurality of cars 1A,... Move in the hoistway 13, the transportation capacity is increased and the waiting time can be greatly shortened.

  Further, unlike a double deck elevator or a twin car type elevator, the circulation type multicar type elevator can move while riding on the same car 1A,... From the lowest floor to the highest floor. Therefore, it is not necessary to use other transportation means, and convenience for the user is high. However, since the overtaking operation cannot be performed, the following car must be stopped while the passenger of the preceding car is stopped for getting on and off. The frequency of stopping the own car due to the stop of other cars increases as the number of cars that circulate increases. This circulating multi-car elevator is suitable when there is a constant traffic flow and a lot of movement between floors occurs.

  FIG. 2 schematically shows a stop floor of the car 10 in one embodiment of the elevator system 1 according to the present invention. In FIG. 2, the symbol “●” indicates the stop floor of the car 10, and both (a) and (b) of FIG. 2 show a case where the express elevator 6 and a plurality of local elevators 7 a to 7 d are combined. . The local elevators 7a to 7d in FIG. 2A are multi-car elevators. The car 10 circulates between the basement 3 or the sky lobbies 4a to 4c provided at every tenth floor in FIG. 2 (a) and the other sky lobbies 4a to 4c or the top floor 4d adjacent to each other. The express elevator 6 stops only on the basement 3, the sky lobbies 4a to 4c and the top floor 4d, and skips the middle floor.

On the other hand, the local elevators 7a to 7d in FIG. 2B are twin car elevators. Similarly to FIG. 2 (a), the local elevators 7a to 7d are connected to other sky lobbies 4a to 4d adjacent to each other from the sky lobbies 4a to 4c provided on the basement (lobby floor) 3 or 10th floor.
Move up and down between 4c or the top floor 4d. Each of the local elevators 7a to 7d has two passenger cars 10d and 10u that can move independently in the vertical direction. The car 10d located on the lower side stops only on the lower floor of the service section of the local elevators 7a to 7d, and the car 10u located on the upper side is located on the upper floor of the service section of the local elevators 7a to 7d. Just stop. The stop floor of the lower car 10d is indicated by the symbol “black triangle”, and the stop floor of the upper car 10u is indicated by the symbol “●”. The express elevator 6 stops only on the basement 3, the sky lobbies 4a to 4c and the top floor 4d.

In the elevator system 1 configured in this way, when visiting the office on the 26th floor, the passenger gets on the express elevator 6 from the basement 3. Then, transfer to the local elevator 7c at the sky lobby 4b on the 20th floor and aim for an office on the 26th floor on the predetermined floor. Alternatively, if the visit destination is a floor close to the sky lobby 4c such as the 29th floor, the express elevator 6 goes up to the sky lobby 4c on the 30th floor. And it uses the local elevator 7c in the descending direction to reach the 29th floor of the predetermined floor.

  According to the present embodiment, since the transfer floors are provided on the upper and lower floors of the service sections of the local elevators 7a to 7d, the basement floor 3, the uppermost floor 4d, and the sky lobby 4a to the transfer floors of the local elevators 7a to 7d. The number of people using 4c can be dispersed. That is, the number of people getting into the local elevators 7a to 7d from the sky lobbies 4a to 4c can be reduced. Therefore, the car 10 of the local elevators 7a to 7d can be reduced, and the elevator system can be saved in space.

  When the slewing circulation type multi-car shown in FIG. 2A is used for the local elevators 7a to 7d, when one of the cars 1A connected by one rope is stopped at the lowest floor, The car 1B is stopped on the top floor. Thereby, it can board simultaneously from two places, 1A and 1B, and can carry many simultaneously. Also, in traffic flows with high congestion such as when going to work, the probability that both of the two cars 1A and 1B will be used increases, and the weight imbalance of the cars 1A and 1B decreases, resulting in energy efficiency. Will be better.

  When the twin car elevator shown in FIG. 2B is used for the local elevators 7a to 7d, the lowest floor of each of the local elevators 7a to 7d is the standby floor of the lower passenger car 10d, and the uppermost floor is the upper elevator. It is assumed that the waiting floor of the car 10u. Then, the service section of the upper car 10u and the lower car 10d is divided between the basement 3 or the sky lobbies 4a to 4c and the uppermost floor 4d adjacent to each other in the vertical direction. With this setting, the probability that the services of the cars 10d and 10u interfere with each other is reduced, and space-saving and efficient transportation is achieved. In addition, if a double deck elevator is used for the express elevator 6 in this embodiment, the area of the lobby floor 3 can be substantially doubled and a large number can be transported at the same time without increasing the elevator occupation area of the entire building. It can improve transportation capacity.

FIG. 3 shows a modification of the above embodiment. The modification shown in FIG. 3A includes the embodiment shown in FIG. 2 and a plurality of express elevators 6a to 6d, and each express elevator 6a to 6d is the lowest floor of the service section of the elevators 6a to 6d. The difference is that it stops only on the top floor. That is, the elevator 6a moves up and down only between the first sky lobby 4a set in the basement 3 and the 10th floor, and stops only in the sky lobby 4a on the basement 3 and the 10th floor. The elevator 6b moves up and down only between the sky lobby 4b on the basement 3 and the 20th floor, and stops only on the basement 3 and the sky lobby 4b. The same applies to the other express elevators 6c and 6d.

  In the modified example shown in FIG. 3 (b), as in the modified example shown in FIG. 3 (a), a plurality of express elevators 6a and 6b are provided, and the service sections of the respective express elevators 6a and 6b are different. However, unlike the modification of FIG. 3A, twin car elevators are used for the express elevators 6a and 6b.

  The stop floor of the car 10d on the lower side of the express elevator 6a is indicated by the symbol “black triangle”. This lower car 10d stops at the uppermost floor of the local elevator 7a and the lowermost floor of the local elevator 7b. The stop floor of the car 10u on the upper side of the express elevator 6a is indicated by the symbol “●”. The upper car 10u stops at the uppermost floor of the local elevator 7b and the lowermost floor of the local elevator 7c.

  Similarly, the stop floor of the passenger car 10d on the lower side of the express elevator 6b is indicated by the symbol “black triangle”. The lower car 10d stops at the uppermost floor of the local elevator 7c and the lowermost floor of the local elevator 7d. The stop floor of the car 10u on the upper side of the express elevator 6b is indicated by the symbol “●”. This upper car 10u stops at the top floor of the local elevator 7d. The stop floors of the express elevators 6a and 6b are any one of the sky lobbies 4a to 4c, the basement floor 3, and the top floor 4d.

  If the stop floor of the elevator system 1 is set as shown in FIG. 3 (a), a person who moves to the upper sky lobby 4c, 4d does not stop the car 10 up to the target sky lobby 4c, 4d. Becomes shorter. In this modification, if the express elevator 6 is a double deck elevator, the degree of congestion in the elevator system can be eased and the transportation capacity can be further improved.

  When the stop floor of the elevator system 1 is set as shown in FIG. 3B, the stop floors of the two cars of the twin car are determined in advance, so that the cars 10d and 10u in the same hoistway 11 are The probability of hindering driving is reduced, and twin car operation efficiency is good. Moreover, the occupation area of the elevator system 1 can be reduced.

  FIG. 4 shows still another modification. In FIG. 5A, at least one end of the service sections of the local elevators 7a to 7e is set on an intermediate floor different from the sky lobbies 4a to 4d. The express elevator 6 stops only in the basement 3 and the sky lobbies 4a to 4d. In this Fig.4 (a), the hull-type circulation type | mold multi-car elevator is used for the local elevators 7a-7e, and the service area of the local elevators 7a-7e is an odd number floor.

  Since the service section is an odd floor, when one car 1A connected by the same rope stops on the middle floor, the other car 1B also stops on the middle floor. Therefore, two different cars 1A and 1B can be simultaneously provided for service in the same sky lobby 4a to 4d, and the operation efficiency of the elevator system 1 is improved. In a traffic flow with a high degree of congestion such as when going to work, there is a high probability that both of the two cars that are stopped on the same floor will be used together, the weight imbalance will be reduced, and the energy efficiency will be improved.

Instead of this modified example, it is also possible to use a double-deck elevator for the express elevator 6 and use a circulation type multi-car elevator for the local elevators 7a to 7e. In this case, since the sky lobby 4 is set as a continuous second floor, if the service section of the local elevators 7a to 7e is set to an even floor, passengers transiting in the sky lobby 4a to 4d move upward or downward. You can enjoy the services of two different cars 1A and 1B.

  Since the departure floors of the local elevators 7b to 7d are set as intermediate floors, the service sections of the local elevators 7a and 7d are particularly limited in the local elevators 7a and 7d including the basement (lowermost floor) or the uppermost floor as service sections. May be too short. In such a case, it is difficult to install a circulating multi-car elevator with a large number of cars, so it is usually preferable to use an elevator.

  In some high-rise buildings 21, the lower floors may be commercial facilities and the office zone may be laid out above the middle floor. In such a building 21, when using an escalator as an elevating means in a commercial facility area, since the utilization rate of the local elevator 7a is low, using a normal elevator is advantageous in terms of installation area and the like. In this case, if the stop floor of the express elevator 6 (symbol “◯” in FIG. 4A) is provided on the floor serving as the boundary between the commercial facility area and the office area, the operation efficiency of the elevator system 1 is further increased.

FIG. 4B shows an example in which the above FIG. 4A is further modified. In the elevator system shown in this figure, the service sections of the local elevators 7a and 7b are expanded to the adjacent sky lobby 4b, top floor 4d, and basement 3 with one sky lobby 4a and 4c interposed therebetween. That is, the service section of the local elevators 7a and 7b is lengthened, and the express elevator 6 is also stopped on the intermediate floor of the service section of the local elevators 7a and 7b.

  Since the departure floors of the local elevators 7a and 7b can be distributed to three locations, the number of passengers waiting in the sky lobbies 4a to 4c can be reduced. Therefore, the elevator hall can be narrowed and the area of the car 10 can be narrowed. This modification is effective for a high-rise building 21 such as a super high-rise building where the number of users per floor is relatively small. Moreover, since the frequency | count of a transfer reduces when using the 11th, 12th, 31st, and 32nd floors which are the floors near the sky lobby 4a, 4c, the convenience of the user of the elevator system 1 increases.

Another embodiment of the present invention is shown in FIG. In the elevator system 1 shown in FIG.
The elevator system 1 shown in (a) further has an express elevator with different stop floors. One express elevator 6b, like the express elevator shown in FIG. 2A, stops at all floors 3 and 4e to 4i located at both ends of the service sections of the local elevators 7a to 7e. On the other hand, the newly added express elevator 6a stops only at the intermediate floors 4a to 4d and the basement (lowermost floor) 3 of the service sections of the local elevators 7b to 7e. According to the present embodiment, the number of passengers waiting in the sky lobbies 4a to 4h can be reduced. Therefore, the elevator hall can be narrowed and the area of the car 10 can be narrowed.

  FIG. 5B shows a modification of the elevator system 1 shown in FIG. In the elevator system 1 shown in FIG. 4A, a circulation type multi-car elevator is used for the local elevators 7a to 7e, and a normal elevator is used for the express elevator 6. However, in the present elevator system 1, twin cars are used for the local elevators 7a to 7e. A double deck elevator is used for the express elevator 6 and the type elevator.

  In FIG. 5 (b), the symbol “●” indicates the upper car 10u of the double deck elevator or the car 10 located above the twin car, and the symbol “black star” indicates the lower car 10d of the double deck elevator, “black triangle”. "Represents the stop floor of the car 10 located below the twin car. Since the express elevator 6 is a double deck elevator, the basement (lowermost floor) 3 and the sky lobbies 4a to 4d have a height corresponding to the second floor that is continuous up and down. Passengers who use the upper floor side of the local elevators 7b to 7d ride on the upper car 10u of the double deck elevator 6 and passengers who use the lower floor side of the local elevators 7b to 7d ride on the lower car 10d of the double deck elevator 6.

  According to this modification, since the departure floors of the local elevators 7b to 7e are set to the intermediate floor, even if the express elevator 6 is a double deck elevator and the local elevators 7b to 7d are twin cars, the area occupied by the elevator system 1 is reduced. Transport capacity can be increased without increasing it. In that case, since the departure floor of the twin car is an intermediate floor, the service zones of the upper car 10 and the lower car 10 can be clearly separated. In order to get on and off the preceding car 10, the following car 10 is not forcibly stopped, and the elevator system 1 can be operated efficiently.

In each of the above embodiments and modifications, the setting of the stop floor of the express elevator 6 can be made variable. For example, when a failure occurs in any of the local elevators 7a to 7e or the service is stopped due to maintenance work, the express elevator 6 is stopped at all floors in the service section of the local elevators 7a to 7e where the service is stopped. Let Thereby, the fall of the service by the stop of the local elevators 7a-7e can be avoided.

  In each of the above embodiments and modifications, the multicar elevator is a slewing circulation type multicar elevator in which two symmetrically arranged car 10 and 10 are connected by a rope, but each car 10 and 10 is independent. It may be a multi-car elevator that drives the vehicle. Even in this case, the area occupied by the elevator can be reduced. Therefore, according to each of the above-described embodiments and modifications, a high transportation capacity can be ensured without increasing the elevator occupation area.
