[Prior Art] Conventionally, when inspecting equipment installed above the car and in the hoistway, a worker climbed onto the top of the corner of the elevator and carried out the inspection while moving the car up and down. When the car is raised or lowered, there is a risk of being pulled into or caught in the counterweight that moves up and down in the opposite direction to the direction in which the car corner is raised or lowered.

ている。Therefore, as shown in Japanese Utility Model Application No. 58-67862, for example, an alarm device is installed on the top of the car, and when the distance between the counterweight and the car becomes within a certain distance, the alarm device is activated. A device that makes a sound has been proposed.

Making such a judgment during inspection work is troublesome, and the warning that the counterweight is approaching may be mistaken for another warning or may be missed, making it difficult to accurately notify that the counterweight is approaching. I couldn't.

を示す電気回路図である。An object of the present invention is to provide an elevator inspection safety device that can accurately notify the approach of a counterweight when an inspection is performed while moving a car. [Means for Solving the Problems] The above purpose is to wrap a main rope with a car at one end and a counterweight at the other end around a sheave on a hoisting rock, and drive the sheave rotationally by the hoisting rock to transport the car to the car. , In an elevator inspection safety device that moves counterweights in opposite directions, there is a switch that is turned on during elevator inspection, and when this switch is turned on, the counterweight approaches the car and the distance This is achieved by installing an audio synchronization device that operates when the balance weight falls within a predetermined value and broadcasts that the counterweight is approaching. [Operation] Because of the above structure, when you stand on the top of the car, turn on the inspection switch, and move the car while inspecting it, the counterweight approaches the car and the distance is When the value falls within a predetermined value, the audio synchronization device operates and broadcasts a synchronization sound that the counterweight is approaching from above or below. It is possible to know that a counterweight is approaching without any judgment, and accidents caused by this can be prevented. [Example] Hereinafter, one embodiment of the present invention will be explained with reference to Figs. FIG. 2 is an electrical circuit diagram showing one embodiment of the notification circuit.

includes a pusher 7B that presses the position detection switch 7A;
7C, and the position of the position detection switch 7A is selected so as to detect when the counterweight 3 approaches the car 2 within a predetermined distance.
Specifically, the distance M1 from the upper end of the car 2 to the upper end of the counterweight 3 is the length of the counterweight 3. The length shall be the sum of the worker's height and allowance.

のを用いている。Next, an example of the notification circuit will be explained with reference to FIG. Between the control power bus lines P and N, there is an operation switch 8 for inspection operation, and a relay contact 9a. The normally open contact 7Aa of the position detection switch 7A and the voice synthesizer operating relay 10 are connected in series. An audio combining device 11 is connected to the audio combining device operation relay 10, and when the contact 10a of the relay 10 is closed, the audio combining device 11 is configured to start broadcasting preset contents. has been done. Further, a warning light 12 is connected in series with the contact 10a. The warning light 12 is installed on top of the car 2, and the warning light 111 is installed on top of the car 2.
Moreover, the speech synthesizer 11 is installed for guiding the arrival floor, guiding the opening/closing operation of the door, etc.
次に点検運転時の動作を説明する。Next, the operation during inspection operation will be explained.

合いおもり3が接近してくることを知ることができる。As shown in Figure 1, we will discuss the case where the power and 1 are increased. Turn on (close) the inspection operation switch 8 to enable inspection operation, get on top of the car 2, and inspect the equipment in the hoistway while raising the car 2.
When the counterweight 3 approaches a predetermined distance above the car while the car 2 is rising, the switch 7A is pressed by the pusher 7B, its constant contact 7Aa closes, and the switch 8 and contact 9a are already closed. Therefore, relay 10 is energized. The energization of the relay 10 closes the constant contact 10a, which activates the voice synthesizer 11 and warning light 12, and the voice synthesizer 1 issues a message saying, ``A counterweight is approaching from above. Please be careful. ”
In conjunction with this, an audio warning message is repeatedly played, and the warning light 12 lights up (blinks). This allows the operator who is performing inspection work while riding on the car 2 to know that the counterweight 3 is approaching.
下降運転で点検を行う場合には、スイッチ7Aが抑圧子
7Cにより押圧され、以下上記と同様に動作し,点検作
業者に下方からつり合いおもり3が接近してくることを
知らせることができる。When inspection is performed in descending operation, the switch 7A is pressed by the suppressor 7C, and the operation is similar to that described above, thereby notifying the inspection operator that the counterweight 3 is approaching from below.

に知らせ、事故を未然に防止することができる.In the above embodiment, the warning light 12 may be removed and only the voice synthesizer 11 may be provided. [Effects of the Invention] As described above, according to the present invention, when the inspection operation switch is turned on and the operator is riding on the upper part of the car and inspecting it while raising and lowering the car, the counterweight approaches the car. When the distance falls within a predetermined value, the voice synthesizer operates and broadcasts, using directly synthesized voice, that the counterweight is approaching from above or below.
Inspection workers can know that a counterweight is approaching without having to make any judgments, and there is no chance that they will misinterpret it as another alarm, and they will be able to accurately notify them of the approach of a counterweight. Accidents can be prevented.
