Description

Description: [Industrial field of use] The present invention relates to an emergency notification device for elevator maintenance personnel.

[Prior Art] An elevator accident not only causes a great deal of trouble to people who use the elevator, but also may lead to personal injury. For this reason, maintenance work is performed on the elevator not only when an accident occurs but also at normal times at regular intervals.

The maintenance staff is dispatched from a dispatching company that has jurisdiction over the elevator and patrols the corresponding elevator for inspection. This maintenance and inspection is usually performed by one person, and includes inspection work in the machine room and inspection work in the pit or on the car. During this work, if a maintenance worker experiences a physical abnormality, for example, if he / she feels sick and falls, he / she may be trapped in that place for a long time unless he / she contacts the outside. It was

As one of the means for this communication, conventionally, each maintenance staff carries a security buzzer, and when an abnormality occurs, operate this buzzer, and the alarm sound generated by this buzzer causes the abnormality to be sent to the dispatch company. There was a case in which a third party other than the one who belonged to was notified and the third party contacted the dispatching company to which the maintenance staff belongs.

[Problems to be Solved by the Invention] In the above-mentioned conventional technology, for example, even if the buzzer is rung during work in the machine room, the buzzer alarm sound cannot be heard outside. The same problem occurred when the vicinity of the elevator was noisy. In any case, with the conventional one, the feeling of leaving it to others was undeniable.

An object of the present invention is to provide an emergency maintenance device for an elevator maintenance worker, which enables a dispatching company to appropriately respond to an emergency during an elevator maintenance work without relying on a third party to manage the maintenance worker. is there.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a switch, which is provided in at least one or more of a machine room of an elevator, a car or a pit, and is operated by a maintenance person. And a notification device which is connected to the switch by wiring and outputs to the telephone line as abnormal data when the switch is operated, and a monitoring center which processes the abnormal data sent from the reporting device through the telephone line. It is composed of.

[Operation] When the switch is operated by the maintenance personnel, abnormal data is output from the notification device to the telephone line and sent to the monitoring center. As a result, the operator of the monitoring center can know to the maintenance staff that an emergency has occurred, and can take necessary measures. Therefore, the dispatch company of the maintenance staff can appropriately respond to the emergency without relying on a third party.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

1 and 2 are diagrams showing an emergency notification device for elevator maintenance personnel according to an embodiment of the present invention. FIG. 1 is an overall schematic diagram, and FIG. 2 is a block diagram.

In FIG. 1, 1 is a car for moving up and down the elevator hoistway 2, 3 is a pit installed at the bottom of the hoistway 2,
4 is a shock absorber provided in the pit 3, 5 is a car operation panel provided in the car 1, 6 is a tail cord connected to the car 7 through a control panel 8 provided in the machine room 7, 9 ,
Numerals 10 and 11 are switches operated by an elevator maintenance staff provided in the pit 3 on the machine room 7 and the car 1. Reference numerals 12, 13 and 14 are communication lines that connect the switches 9, 10, and 11 and a notification device 15 provided on the control panel 8. The notification device 15 is, as shown in FIG. 2, a control device 16 for controlling signals output by operating the switches 9, 10, 11 and a communication device for outputting abnormal data from the control device 16 to a telephone line 18. It is composed of 17 and. Reference numeral 19 is a monitoring center that receives abnormal data from the telephone line 18 and takes necessary actions by the operator.

Now, it is assumed that the elevator maintenance worker who is working in the machine room 7 feels sick and is no longer able to seek rescue by himself. In this case, when the elevator maintenance personnel pushes the switch 9 provided in the machine room 7, a signal is sent to the control device 16 in the notification device 15 via the communication line 12. The control device 16 determines that there is an abnormality, and the abnormality data is output to the telephone line 18 via the communication device 17 and notified to the monitoring center 19.

A monitoring center that the maintenance staff knew of an emergency
The operator of 19 can notify the dispatching company in charge of the occurrence of an emergency and give an instruction to promptly rescue the maintenance staff who feels sick in the elevator machine room 7. As a result, the maintenance personnel can be immediately rescued, and the problem that the maintenance personnel are locked in the machine room 7 for a long time can be solved. The same can be done by operating the switches 10 and 11 even when working inside the pit 3 on the car 1.

In the above embodiment, the switches are provided at three places on the machine room 7, on the car 1 and in the pit 3, but the switches need not necessarily be provided at three places and can be appropriately selected and provided. Also, although an example in which a notification device is newly provided is shown, a terminal device or the like provided in a remote monitoring device for an elevator or a building which has recently been installed in a machine room may be used as the notification device. . Further, although the monitoring center is used as the report destination, the dispatching company to which the maintenance staff belongs may be contacted.

EFFECTS OF THE INVENTION According to the present invention, a maintenance staff dispatching company can immediately respond to an emergency situation during elevator work without relying on a third party, and the maintenance staff can spend a long time in a machine room or the like. The problem of being trapped can be solved.
