Abstract

<P>PROBLEM TO BE SOLVED: To provide an elevator control device capable of preventing passengers from being confined to inside of a car by stopping the car on the nearest floor in preparation for breaking of a wiring material between a control board and the car when the control board inside an elevator machine room is fallen down. <P>SOLUTION: The elevator control device is provided with a means for deenergizing a falling-down detection relay 5 by opening a contact point of a microswitch 4 of a control board falling-down detection device when earthquake occurs during traveling of the car and the control board is removed from a control board mounting table and is fallen down due to the shaking of the earthquake, energizing a nearest floor traveling command relay 6 by closing a contact point A1 of the falling-down detection relay 5 and stopping the car on the nearest floor by closing a contact point B2 of the nearest floor traveling command relay 6. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to an elevator control device suitable for detecting the fall of a control panel provided in an elevator machine room.

As this type of technology, as disclosed in Japanese Patent Laid-Open No. 9-326229, it is provided with a detector that senses excessive shaking and vibration such as an earthquake, and is provided in a building facility when the detector operates. An invention is known in which a circuit breaker for wiring is operated to shut off a primary power source of a building (see Patent Document 1).
Japanese Patent Laid-Open No. 9-326229 (page 4 FIG. 1)

  If the control panel overturns due to excessive shaking or vibration such as an earthquake, excessive tension will be applied to the wiring material connecting the control panel and the cage, and if this state continues, it will not be known when the wiring will be disconnected, and if it is disconnected When the car could not be commanded to run and the car was running, there was a problem that the car suddenly stopped and the passenger was trapped in the car.

  The present invention has been made in view of the above problems, and includes a control panel overturn detection device that detects an abnormal installation of the control panel, so that the control panel can be controlled when the control panel falls due to excessive shaking such as an earthquake. To provide an elevator control device that prevents a passenger from being trapped in the car by stopping the car at the nearest floor in preparation for the wiring material between the panel and the car being disconnected due to tension. .

  In order to achieve this object, the invention according to claim 1 of the present invention provides a control panel between the control panel in the elevator machine room and the control panel mounting base for fixing the control panel to the machine room floor. This is achieved by providing a control panel overturn detection device that detects the disconnection.

  According to the present invention, for example, when the control panel falls off the control panel mounting table due to excessive shaking such as an earthquake, the control panel overturn detection device operates to stop the car at the nearest floor. , Can prevent the passengers from being trapped in the car.

  Hereinafter, an embodiment of the present invention will be described with reference to FIGS.

  FIG. 1 shows a normal state of control panel installation in the elevator machine room, and FIG. 2 shows a state where the control panel is overturned.

  1 and 2, 1 is a control panel, 2 is a control panel mounting base, 3 is a control panel overturn detection device, 4 is a micro switch built in the control panel overturn detection device 3 and is closed by the load of the control panel. Has contacts.

  FIG. 3 shows an electrical connection diagram of this apparatus. In the figure, 5 is a fall detection relay that is de-energized when the control panel fall detection device 3 operates and the built-in contact of the micro switch 4 is opened, and 6 is that the contact A1 of the fall detection relay 5 is closed. The nearest floor travel command relay that is incapacitated is shown.

  Next, a case where the control panel falls while the elevator is running due to an earthquake shake will be described with reference to the drawings.

  When an earthquake occurs while the car is running and the control panel 1 falls off the control panel mounting base 2 due to shaking, the contact of the micro switch 4 of the control panel overturn detection device 3 is closed, and the fall detection relay 5 is de-energized, and the contact A1 of the fall detection relay 5 is closed to activate the nearest floor travel command relay 6, and the contact B2 of the nearest floor travel command relay 6 is closed to bring the car to the nearest floor. Stop.

  According to this embodiment, when the control panel falls down due to an earthquake or the like while the car is running, the car is stopped at the nearest floor in preparation for disconnection of the wiring material between the control panel and the car. Thus, it is possible to prevent passengers from being trapped in the cabin.

1 is a structural diagram showing an embodiment of the present invention. 1 is a structural diagram showing an embodiment of the present invention. It is the whole electrical connection diagram.
