    Vibration reduction equipment in elevator
    The present invention relates to an elevator, and more particularly to a car vibration reduction device that can mitigate the transmission of the vibration of the carttle to the cage when the elevator is running.
    An elevator is a vertical means of transporting a passenger or a load vertically according to the mutual movement of the car and the counterweight hanging on the main rope while moving along the drive sheave in which the main rope rotates.
    The car, on the other hand, consists of a cage in which the passenger is boarding and a frame surrounding the cage. If the building bends over time or the guide rail itself is wheeled, the bottle moves and vibrates due to the bending of the guide rail and the step of the connection part.
    In addition, the carttle is connected to the hoist that drives the elevator by a rope, and vibration of the hoist and the rope are transmitted to the carttle. The vibration of the kettle is transmitted to the cage in which the passenger is riding, and a vibration reduction device is installed between the cage and the cage to alleviate this.
    1 is a schematic configuration diagram of a conventional elevator.
    Reference numeral 1 is a hoist that drives the elevator to move the car of the elevator. On the other hand, the car is composed of a bottle 3 and a cage (4).
    The main rope 2 causes the car and the counterweight 6 to move up and down as the motor of the hoist 1 rotates. As the car moves up and down, the elevator carries passengers or cargo vertically, where the car and counterweight 6 move up and down along the guide rail 8. In the figure, reference numeral 5 denotes a vibration reducing device installed between the bottle 3 and the cage 4, and reference numeral 7 shows a compensation pulley.
    Referring to the operation of the prior art device configured as described above is as follows.
    The bending of the guide rail 8 in the manufacturing process of the guide rail 8 or the installation error in the installation process, the bending of the guide rail 8 and the step between the guide rail 8 is generated. In addition, the deformation of the building over time is the guide rail (8) is bent.
    When a problem occurs in the straightness of the guide rail 8 as described above, the vibration is transmitted to the bottle 3 while the elevator is running. In addition, the main rope 3 is shaken by the vibration of the hoisting machine 1 or by the imbalance of various rotating bodies and by its own shaking, which also adversely affects the vibration of the bottle 3.
    The vibration of the kettle 3 is transmitted to the cage in which the passenger is riding. At this time, the vibration is reduced by the vibration reducing device 5 installed between the cage 3 and the cage 4, so that the passengers may ride more comfortably. Given.
    As shown in FIG. 2, the vibration reducing device 5 is constituted by a dustproof rubber 5a and metal fixing pieces 5b formed above and below.
    By the way, the anti-vibration rubber (5a) serves as a spring and is designed on the basis of when the passenger of the elevator to the maximum.
    The conventional anti-vibration rubber 5a has a spring constant value designed to avoid all external excitation frequencies of the system based on when the passenger is full and thus does not cause resonance when the passenger is full. .
    However, in the case of elevators, the natural frequency of the elevator changes as there are many passengers. In most cases, passengers ride in an elevator with a full load, and most ride under half the rated load. In particular, apartments often burn 1-2 people, but the natural frequency of the system is increased, and the frequency coincides with the excitation frequency of external disturbance. At this time, the resonance is often generated, the system transmission characteristics are deteriorated and adversely affect the vibration of the elevator.
    The present invention was devised to solve the problems of the prior art as described above, and the passenger load as a relatively simple structure to attenuate the vibration transmitted to the cage by rail and rope when the elevator travels the guide rail in the hoistway Car vibration of the elevator to improve vibration transmission characteristics by minimizing the vibration constant of the elevator by minimizing the vibration of the elevator so that passengers in the cage of the elevator can feel anxious and uncomfortable while riding the elevator and have a comfortable ride The purpose is to provide an abatement device.
    In order to achieve the above object, the present invention, between the bottom of the cage constituting the car and the bottom of the cage is installed in the form of a plate-shaped circular spring whose spring constant value is changed according to the change in the weight of the cage (number of passengers or load) It is characterized by one.
    In addition, the friction damper for changing the relative displacement change to the frictional force between the bottom of the cage and the bottom of the cage constituting the car is characterized in that each installed is configured.
    1 is a schematic configuration diagram of a conventional elevator.
    Figure 2 is a detailed front view of the vibration reducing device shown in FIG.
    Figure 3a, 3b is a configuration and operation state of the vibration reducing device of the present invention.

    4: cage
    10: round spring
    12: Bolt
    14, 16; Friction damper
    Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
    In the description of the present invention, the same or equivalent parts as in the prior art will be described with the same reference numerals.
    Figure 3a, 3b shows a configuration and operation state diagram of the vibration reducing device of the present invention.
    As shown, a plate-shaped circular spring 10 is elastically installed between the bottom of the cage 4 constituting the car and the bottom of the bottle 3, and the circular spring 10 is fixed to the bolt 12. It is fixed to the side of the bottle 3 by means.
    And friction dampers 14, 16 for changing the relative change in displacement between the bottom of the cage (4) and the bottom of the cage 3 to the friction force is provided and configured respectively.
    According to the present invention configured as described above, when the passenger rides a little in the cage 4, the circular spring 10 maintains a substantially circular shape as shown in FIG. 3A, and the spring constant value is low. On the other hand, when the passenger rides a lot in the cage 4, the circular spring 10 is compressed in an elliptic shape to have a shape as shown in FIG. 3b, and the spring constant value increases as the supporting area for the load increases.
    Therefore, the ratio of mass to spring constant is constant so that the natural frequency of the system becomes constant regardless of the passenger's load. Therefore, if the system's natural frequency value is initially designed to avoid all external excitation frequencies, resonance will not occur regardless of the number of passengers with little or no load.
    Meanwhile, the friction dampers 14 and 16 generate friction while causing relative displacement of the cage 4 and the cage 3 to serve as friction dampers, thereby reducing vibration.
    As described above, the present invention minimizes the vibration of the elevator by maintaining a constant value of the natural frequency of the system through a vibration reducing device that also changes the spring constant value as the number of passengers (or loads) in the car changes. Passengers in the cage have the effect of having a comfortable ride by minimizing the anxiety and discomfort felt when driving the elevator.
