Abstract

PURPOSE: A ropeless elevator is provided to freely move horizontally and vertically inside a three-dimensional passageway prepared in a building and to simultaneously operate plural cages in the passageway. CONSTITUTION: A passageway(10) is connected vertically and horizontally for operating simultaneously plural cages(40). A primary coil(30) for horizontal movement and plural coils(20) for vertical movement are mounted along an inner side face of the passageway. For avoiding application of magnetic force inward of the cage and for moving the cage by magnetic action between the cages corresponding to the secondary coil(30) for horizontal movement and to the primary coil(20) for vertical movement, a pair of secondary magnet assembly bodies(A) are composed in upper and lower areas of cage. The secondary magnet assembly body(A) is arranged at an isolated location from the cage as to be out of influence of magnetic force and with no harm to human body. Thereby, an additional magnetic shielding instrument is unnecessary and transformation by outer force is prevented. Accordingly light weight of cage is enabled and balance of cage is maintained.

Description

Ropeless elevator {ROPELESS ELEVATOR}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ropeless elevator, and more particularly, to a ropeless elevator in which a vertical and horizontal movement is free within a three-dimensional passage provided inside a building, and a plurality of cages can be simultaneously operated in the passage. .

In recent years, in order to increase the utility of buildings, the structure is becoming very high-rise, and in response to the trend of the high-rise of buildings, technical research on elevators for transporting manpower inside the building is steadily progressing.

In order to operate an elevator system suitable for a high-rise building as described above, it is necessary to overcome the limitations of the existing rope driving method, and a new concept of elevator driven by a new actuator should be introduced.

In addition to the related problems with the drive system and the actuator as the drive source, a new type of elevator is inevitably required to maximize transportation efficiency and space utilization suitable for a building structure.

Accordingly, in view of the above conditions, an elevator applicable to a high-rise building can simultaneously operate a plurality of cages within a single passage, and the cage can move freely in the vertical / horizontal direction along the three-dimensional passage inside the building. It should be able to function as a comprehensive transportation system that can be used in connection with nearby buildings and underpasses.

The elevator currently being used adopts the elevating driving method by the towing of the rope, and the design should not only consider the load and vibration characteristics of the cage proportional to the number of floors, but also make it impossible to change the vertical / horizontal direction of the cage. Since there is a limit, it is urgent to have an alternative structure to overcome this problem.

Conventional ropeless elevator for solving the problem of such a rope-driven elevator is a passage provided with the vertical coil primary coil 120 on both inner surfaces in the vertical direction, as in the example shown in Figures 1 to 4 110 and a cage 140 accommodated in the passage 110 and provided with a secondary magnet 162 for vertical movement on both sides corresponding to the primary coil 120 for vertical movement. will be.

When the ropeless elevator is excited so that thrust may be generated in the vertical movement primary coil 120 at the passage 110 side, the thrust may be generated in the vertical movement secondary magnet 162 facing the same. The cage 140 can be elevated in the vertical direction.

However, in the conventional ropeless elevator, since the resin secondary magnet 162 is directly fixed on both outer wall surfaces of the cage 140, a strong magnetic force is generated to the passengers who ride in the cage 140. There was a problem that adversely affects. Therefore, a separate magnetic shield must be provided in view of such a problem.

In addition, since the thrust from the vertical movement primary coil 120 acts on the vertical movement secondary magnet 162, there was a problem that the cage 140 may be deformed. In order to compensate for this problem, the rigidity of the cage 140 should be made high, which is in conflict with design conditions in which the cage 140 should be made as lightweight as possible.

In addition, since the conventional ropeless elevator is capable of only elevating driving, it is not only able to perform a function as a comprehensive transportation system having horizontal mobility, but also a structure in which a plurality of cages 140 cannot be operated simultaneously. In order to maintain the equilibrium in the gravity direction of the cage 140, a separate posture correction drive source and a power source for driving the cage have to be dividedly supplied, thereby causing the power supply of the cage 140 to become unstable.

Accordingly, the present invention has been made to solve the above problems, and by installing the secondary magnet assembly in a position isolated from the side of the cage, not only harmless to the human body, but also need a separate magnetic shield means, The cage can be prevented from being deformed, the cage can maintain its own equilibrium without the need for a separate posture correction drive source, operate multiple cages at the same time, and function as a comprehensive transport system free of vertical and horizontal movement. It is an object of the present invention to provide a ropeless elevator.
