Abstract

(57) [Abstract] [Purpose] To provide a test device for an intercom system for elevators, which does not require the test device to be attached or detached at each test. [Structure] The present invention is a test in which a control room intercom 1 is provided with a buzzer device 4 for generating sound and a handset remover 3 of the intercom, and at the same time, the car operation panel is operated with the buzzer 4 and handset remover 3. A switch 6 is provided.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a test device for an intercom device for an elevator.

[0002]

[Prior Art]

 As a conventional device of this type, as described in Japanese Patent Laid-Open No. 63-262381, a call button is provided on the elevator car operation panel, and the intercom of the elevator car is operated by operating the call button. An intercom device for an elevator, which is adapted to make a call with an intercom in a management room, wherein a device for generating a sound while operating the call button for a predetermined time is provided on the operating board, and the intercom for the management room. It has been proposed that a part be provided with a buzzer device that generates sound.

[0003]

[Problems to be solved by the device]

 However, the above-mentioned conventional device has a problem that the test device must be installed on both the car side and the control room side each time the test is performed, and removed when the test is completed, which complicates the test work. .

An object of the present invention is to provide a test device for an intercom system for elevators, which does not require the test device to be attached or detached at each test.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides an elevator car operation panel with a call button, and by operating the call button, the elevator car intercom and the intercom in the control room can talk with each other. In the interphone device, a test switch that provides the intercom in the control room with a buzzer means for generating sound and a means for removing the handset of the intercom, and activates the buzzer means and means for removing the handset on the car operation panel. Is provided.

[0006]

[Action]

 Due to the above configuration, when the intercom handset test switch is turned on when the intercom test is performed, the handset disconnection means is activated and the intercom handset in the control room is lifted to the on-hook state and the call is made. The buzzer sounds at the same time as it becomes possible. If this buzzer sounds through the handset of the intercom in the control room and is heard from the speaker (or handset) of the intercom in the car, it means that there is no abnormality in the line that connects both intercoms. If not, there is an abnormality. It will be.

As described above, the presence or absence of abnormality in both intercom lines can be tested by operating from inside the car, and it is not necessary to attach and detach the test device each time the test is performed.

[0008]

【Example】

 An embodiment of the present invention will be described below with reference to FIG.

Reference numeral 1 is an intercom installed in the control room, 2 is a handset of the control room intercom 1, 3 is a handset remover installed in the control room intercom 1, and 3 A is a handset remover 3. An electromagnet, 4 is a buzzer device provided in the intercom 1 of the control room, 5 is a contact point that is closed when the maintenance switch is turned on for maintenance operation of the car, and 6 is an intercom (not shown) in the car. The contact of the call button is shown. Since the connection of the call circuit between the intercom in the car and the intercom in the control room is the same as the conventional one, it is omitted.

Next, a test procedure of the intercom will be described. The inspector closes the contact 5 by switching the elevator to maintenance operation. After that, by operating the intercom call button in the car, the contact 6 is closed and energized, the electromagnet 3A is excited, the handset removing device 3 is activated, and the handset 2 is lifted to be in the on-hook state and ready for a call. . At the same time, the buzzer device 4 is energized and sounds. By hearing this buzzer sound from the intercom (or handset) in the car through the handset 2, it can be confirmed that there is no abnormality in both intercoms and the line connecting the intercoms.

As described above, according to the present embodiment, the inspector can perform the interphone call test simply by switching the elevator to the maintenance operation and operating the call button of the intercom in the car. It is not necessary to attach or remove the test device and buzzer device each time the test is performed.

[0012]

[Effect of the device]

 As described above, according to the present invention, it is possible to provide a test device for an intercom system for elevators, which does not require the test device to be attached or detached at each test.
