Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an air conditioner for an elevator that reduces the influence of an air flow that occurs when a car and a counterweight are passing each other.
[0002]
[Prior art]
In recent years, the number of high-rise buildings has been increasing, and the demand for higher-speed elevators has also increased.
[0003]
However, various problems have arisen with the speeding up of the elevator. For example, when the car is running, there is a problem that the car is vibrated or uncomfortable noise is generated due to the influence of the air flow generated when the car and the counterweight are passing each other.
[0004]
Therefore, conventionally, in order to reduce the vibration and noise of the car as much as possible, the following countermeasure techniques have been proposed.
[0005]
FIG. 6 is a block diagram for explaining a conventional air conditioner applied to a car.
[0006]
In the figure, 1 is a car that carries the elevator user to the destination floor, 2 is an upper and lower part of the car 1, and the air flow generated when the car 1 and the counterweight (not shown) are passing each other. It is a basket air conditioner that regulates the wind.
[0007]
In the car air conditioner 2, a rope passage opening is formed at a location corresponding to a passage portion of a main rope 3 that suspends the car 1 or a compen- sion rope 4 that is connected to the bottom of the car 1. Furthermore, a pair of rope fixing plates 5 and 5 ′ are provided on the lead-out path of the main rope 3 and the compen- sion rope 4 that passes through the rope passage opening of the car air conditioner 2 and sandwiches and fixes the ropes 3 and 4 from both sides. ing.
[0008]
As shown in FIG. 7, the car air conditioner 2 installed on the upper portion of the car 1 has a plate body in which the side of the surface of the counterweight and the counterweight protrudes substantially vertically, and a counterbalance of the counterweight from the top of the protruding plate body. And a downwardly inclined plate body that is inclined downward in a direction opposite to the surface so as to have a predetermined angle or a required curved surface shape, and is formed with a rope passage opening portion 6 through which the main rope 3 passes. ing. On the other hand, the pair of rope fixing plates 5 and 5 ′ sandwich a plurality of main ropes 3 from both sides and are fixed by bolts and nuts 7 as shown in FIG. 10. Reference numerals 8 and 8 'denote airflows which flow against the rope fixing plates 5 and 5', 9 denotes a car support frame at the top of the car, and 10 denotes a spring.
[0009]
Next, FIG. 8 is a configuration diagram in which a conventional air conditioner is applied to the counterweight.
[0010]
In the figure, 11 is a counterweight that balances the weight of the car 1, and the car 1 is suspended from one end of the main rope 3 that is stretched over a hoisting machine (not shown). A counterweight 11 is suspended from the end side. A weight air conditioner 12 is attached to the upper and lower portions of the counterweight 11 in the same manner as the car 1. Further, a pair of rope fixing plates 13 and 13 ′ are provided on the lead-out path of the main rope 3 and the compen- sion rope 4 that pass through the rope passage opening of the weight air conditioner 12, and the ropes 3 and 4 are sandwiched and fixed from both sides. ing.
[0011]
Specifically, as shown in FIG. 9, the weight air conditioner 12 is attached to the upper and lower portions of the counterweight 11 and protrudes so that the side of the passing surface with the car 1 is substantially flush with the counterweight 11. The lower plate is tilted downward so as to have a predetermined angle or a required curved shape in a direction opposite to the passing surface side of the car 1 from the top of the projecting plate. And a descending inclined plate body in which a rope passage opening portion 14 is formed. 15 and 15 'are the airflows which flow against the rope fixing plates 13 and 13', 16 is a weight support frame above the counterweight, and 17 is a spring.
[0012]
Therefore, when the car air conditioner 2 and the weight air conditioner 12 are attached to the upper and lower parts of the counterweight 11 as described above, the air conditioner 2, because of interference with other devices and space restrictions. In many cases, the rope fixing plates 5, 5 ′, 13, 13 ′ cannot be accommodated in the inner wall 12. As a result, the rope fixing plates 5, 5 ′, 13, 13 ′ are projected outside the air conditioners 2, 12. It is attached.
[0013]
[Problems to be solved by the invention]
Therefore, in the elevator air conditioner as described above, the attachment of the rope fixing plates 5, 5 ', 13, 13' for fixing the main rope 3 and the compen- ment rope 4 consisting of a plurality of pieces is extended in the vertical direction. Since the rope fixing plates 5-5 ′ and 13-13 ′ are attached to the ropes 3 and 4 so as to protrude horizontally so as to be substantially orthogonal to each other, the air flow generated when the car 1 and the weight 11 pass each other. Directly hits the pair of rope fixing plates 5-5 ′ and 13-13 ′, which causes generation of vibration, noise, and the like. Further, the rope fixing plates 5-5 ′ and 13-13 ′ have problems such as not only the cause of occurrence of vibration and noise, but also the appearance of the prospective elevator.
[0014]
The present invention has been made in view of the above circumstances, and is designed to be integrated with the rope fixing plate so that the air flow generated when passing between the carriage and the counterweight is not affected by the rope fixing plate. It is possible to provide an air conditioning device for an elevator that reduces the amount of noise.
[0015]
[Means for Solving the Problems]
In order to solve the above-described problems, an air conditioning apparatus for an elevator according to the present invention is provided on the upper and lower portions of one or both of a passenger car and a counterweight, and the passing surface side of the passenger car and the counterweight protrudes in the vertical direction. And a passage portion of a rope that is inclined downwardly with a predetermined angle or a required curved shape in a direction opposite to the passing surface side from the top of the protruding plate body, and is connected to the car and the counterweight in and a downwardly inclined plate body forming the rope openings, the air flow generated at the time of passing, the rectification apparatus main body to flow along the downwardly inclined plate member opposite to the passing surface side, the downward inclined plate member surface and almost the same fitting the rope opening of the rectifier device main body so that the surface position engaged, is provided and a pair of rope fixing plate body sandwiching the rope passing through the rope opening from both sides It is formed.
[0016]
Since the present invention has a configuration as described above, a pair of rope fixing plates that sandwich the rope from both sides are fitted into the rope passage opening portion of the air conditioner main body. This eliminates the problem of the turbulent flow caused by the air flow generated at the time of crossing with the rope fixing plate body, thereby reducing vibration and noise.
[0017]
The air conditioner main body includes a protruding plate body in which the passing surface side of the car and the counterweight protrudes in the vertical direction, and a predetermined angle or direction from the top of the protruding plate body in the direction opposite to the passing surface side. If it is composed of a downwardly inclined plate body that is inclined downward with a required curved surface shape and has a rope opening formed in the rope passage part, the air flow generated when passing between the carriage and the counterweight is reduced. Since it flows along the top surface of the rope fixing plate, the amount of air entering between the car and the counterweight is reduced, and most of the air is distributed to the outside of the car and the counterweight. It is also possible to reduce the noise of the air flow hitting the rope fixing plate.
[0018]
Furthermore, the pair of rope fixing plate bodies are fitted to the rope opening so that the surface of the fixed plate body is substantially in the same plane position as the descending inclined plate body, so that the rider and the counterweight pass each other. The air flow that is sometimes generated can flow along the descending inclined plate without being affected by the rope fixing plate.
[0019]
Furthermore, as the pair of rope fixing plate bodies, an elastic body is attached to at least the upper side surface portion and the lower side surface portion of the rope opening, or the entire rope fixing plate body is formed of a member that absorbs external force due to the rope swing. Then, since the external force including the vibration caused by the swing of the rope is absorbed, it is not transmitted to the air conditioner main body, and consequently the car and the counterweight, so that the vibration can be further reduced.
[0020]
