Description

  Embodiments of the present invention relate to an elevator apparatus having a function of moving a car stopped between floors to the nearest floor.

  In general, when a power outage occurs during a disaster or a failure occurs on the hoisting machine side, the operating elevator stops. At this time, if the elevator car stops between the floors, the passenger is trapped in the elevator car stopped between the floors. In such a case, it is necessary to move the car to the nearest floor and rescue the passenger. As a means to move this car to the nearest floor, the car is attached to the car frame by a pantograph-like extension mechanism. It has been proposed to extend the car to the nearest floor (see, for example, Patent Document 1).

JP 2008-68945 A

  However, the pantograph-like expansion / contraction mechanism makes it difficult to take a sufficient movement distance due to its structure, and the movement direction also only lowers the car due to its own weight, and it is difficult to stop at any position. There was room for improvement.

  For this reason, a subject is providing the elevator apparatus comprised so that the passenger car stopped between floors can be arbitrarily moved to any nearest floor up and down.

  According to an embodiment of the present invention, an elevator apparatus is installed that can move up and down a moving body including a car in a hoistway that penetrates between floors of a building up and down, and moves the car to any floor. The moving body has a moving mechanism that can move the car in the up and down direction in the moving body by a distance of up to the first floor and can stop at any position. The moving mechanism is operated by operating an emergency escape button provided inside or outside the car, and the car is moved to the nearest floor.

It is a figure which shows the principal part of the elevator apparatus which concerns on one embodiment of this invention. It is a figure which shows the whole schematic structure of one embodiment of this invention.

  Hereinafter, an elevator apparatus according to an embodiment of the present invention will be described in detail with reference to the drawings.

  First, a schematic configuration of the entire elevator apparatus according to this embodiment will be described with reference to FIG. In FIG. 2, a hoistway 14 penetrating up and down each floor is provided in a building 10, and a moving body 12 including a elevator car (to be described later) and a counterweight 18 are illustrated in the hoistway 14. It is provided so that it can be raised and lowered by a guide rail that does not. The moving body 12 and the counterweight 18 are connected to each other by a rope 19 wound around a sheave of the hoisting machine 17, and are driven to move up and down with the rotation of the hoisting machine 17.

  Hall call registration devices 15 are provided in the elevator halls on the floors, which are provided on the moving body 12 and can stop a passenger car, which will be described later. In addition, a car call registration device that designates a destination floor by a passenger's operation is provided in the car of the moving body 12. The elevator operation control device 11 is connected to each hall call registration device 15 and the car call registration device through the transmission line 13, and controls the hoisting machine 17 in accordance with the call from the hall call registration device 15. Move to the destination floor.

  Next, referring to FIG. 1, the structure of the moving body 12, which is the main part of this embodiment, will be described. The movable body 12 has an upper beam 21 and a lower beam 22, and a pair of ball screws 23 are provided in the vertical direction between them. Further, a car 24 supported by the ball screws 23 so as to move up and down is provided. Provided. The upper beam 21 and the lower beam 22 are arranged in the horizontal direction with a vertical interval. The pair of ball screws 23 are rotatably held on the upper beam 21 and the lower beam 22, respectively, and are rotationally driven in synchronization with each other by a motor 26 using a battery (not shown) as a power source. The car 24 is disposed between the upper beam 21 and the lower beam 22 and is screwed with a pair of ball screws 23, and is guided and driven in the vertical direction as the ball screws 23 rotate. The moving distance of the car 24 accompanying the rotation of the ball screw 23 is the maximum distance between the first floors. The distance between the first floors is a moving distance from the floor surface of the car 24 to the floor surface of the upper floor on the first floor from the floor surface of the lower floor.

  An emergency escape button 27 is provided in the car 24 together with the car registration device (not shown) described above. The emergency escape button 27 rotates the motor 26 in the normal direction or the reverse direction by the operation. The car 24 can move in any direction between the upper beam 21 and the lower beam 22 due to the screwed relationship with the pair of ball screws 23, and this movement can be performed at an arbitrary position. Can be stopped.

  Further, an operation handle 28 is installed in the car 24, and by rotating the handle 28, a sprocket 30 provided on the upper beam 21 is rotated via a chain 29, and a gear (not shown) integral with the sprocket 30 is provided. By rotating the ball screw 23, the car 24 may be moved. If comprised in this way, even if the power supply of the battery which is not illustrated cuts off, the passenger car 24 can be moved manually. In this case, since the distance between the car 24 and the upper beam 21 changes, it goes without saying that a mechanism (not shown) that keeps the tension of the chain 29 constant is provided.

  As described above, the moving body 12 can move the car 24 in the up-and-down direction in the moving body 12 by up to one floor distance, and can be stopped at any position. Is possible. These operations can be performed by operating the emergency escape button 27 or the handle 28 provided in the car 24, and the car 24 can be moved to the nearest floor when the moving body 12 is stopped. Become.

  Further, if the car 24 is provided with landing zone detecting means (not shown) for detecting that the car 24 has entered the landing zone with the floor, the detection result of the landing zone detecting means is used. The passenger can be informed by the notification means such as a buzzer provided in the car 24 that the car 24 has entered the landing zone with the corresponding floor.

  In the above configuration, when a power failure occurs due to a disaster or the like during operation of the elevator or a failure occurs on the hoisting machine 17 side, the moving body 12 moving in the hoistway 14 is moved to the hoisting machine 17. Since the provided brake device (not shown) operates toward the fail-safe side, the brake device stops in the hoistway 14. If the mobile body 12 stops between floors at this time, the passenger in the passenger car 24 will be confined between the floors. When the emergency escape button 27 provided in the car 24 is operated in this confined state, the motor 26 provided on the upper beam 21 is operated by the power source from the battery, and the ball screw 23 is rotated to rotate the car 24. Is raised or lowered. In this case, since the position of the car 24 in the hoistway 14 is detected by a position sensor (not shown) provided in the hoistway 14, the direction from the stop position to the nearest floor is either up or down. The car 24 is moved. Further, if the moving mechanism of the car 24 composed of the motor 26 and the ball screw 23 is provided with a detecting means such as a pulse generator for detecting the moving amount of the car 24, the detected moving amount is put in the car 24. It can be displayed on the provided display portion.

  When the car 24 enters the landing range with the nearest floor due to this movement, this is detected and a notification means such as a buzzer notifies, so the moving mechanism described above is stopped and the car is moved to the nearest floor. Land on the floor. This landing control may be performed manually by operating the emergency escape button 27 or the handle 28 in accordance with the notification that the landing zone has been entered, or based on the detection signal of the landing zone detection means. You may be automatically landed.

  As described above, the car 24 can be moved in the up and down directions in the movable body 12 by a maximum distance between the first floor and can be stopped at an arbitrary position. Therefore, even if the moving body 12 stops between the floors, the car 24 can be moved either up or down to land on the nearest floor, and the passengers in the car 24 can be rescued. It becomes possible. In particular, since the car 24 can be moved in either the upper or lower direction, a safer floor can be selected from the upper and lower floors for landing. In addition, since this movement can be stopped at an arbitrary position, it is possible to make the passenger car and the floor floor coincide with each other, and the safety at the time of passenger evacuation is improved.

  In the above embodiment, the moving mechanism that moves the car 24 in the moving body 12 is exemplified by the one using the screwed relationship with the ball screw 23 that is rotationally driven by the motor 26 or the handle 30. This is because the weight of the car 24 does not act as a large load on the motor 26 or the handle 30, operates relatively lightly, and consumes relatively little battery. However, the present invention is not limited to this, and other moving mechanisms such as a slidable moving mechanism may be used. In this case, a pair of guide rails are provided between the upper beam 21 and the lower beam 22 in place of the ball screw 23 to support the car 24 so that the car 24 can move up and down, and the vertical projection plane of the car 24 is deviated. A guide rail for a second counterweight is provided on the side surface of the moving body 12, and a small hoisting machine that operates on a battery power source is provided on the upper beam 21, and the sheave on the sheave and the second counterweight. A rope that connects the two is wrapped around to form a sword-type moving mechanism.

  If comprised in this way, the load of a small hoisting machine is small and the consumption of a battery can also be reduced relatively. Moreover, the car 24 can be moved in any direction up and down, and can be stopped at an arbitrary position.

  In this way, any movement mechanism can be used as long as it consumes relatively little battery, can move the car in any direction up and down, and can stop at any position. Good.

  Moreover, although the case where the emergency escape button 27 is provided in the car 24 is illustrated in the above embodiment, the car 24 is moved from the outside by being provided in an elevator hall or a building management room on the 24th floor of the car. You may comprise as follows.

  Although several embodiments of the present invention have been described, these embodiments have been presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
