Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an escalator brake braking distance measuring device for measuring a braking distance from when an escalator is braked until it is actually stopped.

[0002]

2. Description of the Related Art What is the braking distance of an escalator?
In the stop control of the escalator, it represents the distance from when the brake operates until the escalator actually stops. For example, as shown in FIG. 6, a portable switch 1 that can be connected to an escalator control device and can give a control command. The operator holds the brake switch and manually operates the escalator with the portable switch 1 to measure the braking distance.

That is, when a mark previously attached to the moving handrail 7 reaches an arbitrary point, the brake is operated by releasing the finger from the operation button of the portable switch 1. However, the escalator operates the brake by inertia. Also, the brake braking distance is measured by visually measuring the distance (or tread) on the moving handrail 7 from the arbitrary point to the point at which it actually stops because it stops after slipping a certain distance. It is done like this.

[0004]

However, in the above-mentioned distance measuring method, the operator stops the escalator after a mark comes to an arbitrary point, and the braking distance at that time is measured visually, so that a measurement error occurs. Is large and it is very difficult to measure an accurate value.Therefore, in order to obtain an accurate value, it is necessary to repeat the operation many times to find the average value, which is time-consuming and accurate. I couldn't get a good number.

The present invention has been made to solve the above-mentioned problems of the conventional example, and an object thereof is to obtain a brake braking distance measuring device for an escalator capable of accurately measuring the brake braking distance in a short time. It is a thing.

DISCLOSURE OF THE INVENTION A brake braking distance measuring device for an escalator according to the present invention is a portable switch which is connected to an escalator control device via a cable and can give a driving or stopping command. Braking until it actually stops after sending the stop command by being connected together through the connector and being supplied with power when the stop command is sent by the portable switch and driven and contacting the handrail of the escalator A distance measuring device for measuring a distance is provided.

[0007]

In the brake braking distance measuring device for an escalator according to the present invention, a distance integrally connected via a connector to a portable switch which is connected to the escalator control device via a cable and can give an operation or stop command. By supplying power to the measuring device when the stop command is sent by the portable switch and driving it, and contacting this distance measuring device with the handrail of the escalator, the braking distance until the actual stop after sending the stop command is measured. To be done.

【Example】

Example 1. A specific example of the present invention will be described with reference to the drawings. FIG. 1 shows the entire configuration of a brake braking distance measuring device of an escalator. A pen-type map meter which is a distance measuring device 4 is connected to a portable switch 1 with a connector 2
It is the figure attached with the connector fixing cap 6.

FIG. 2 is an exploded view of FIG. 1. During normal manual operation, the connector cap portion 2b is attached to the male portion 2a of the connector 2 of the portable switch 1 for use, and the connector cap is used only when measuring the braking distance. 2b is removed and the female connector portion 5 of the distance measuring device 4 is replaced with the male connector portion 2 described above.
The portable switch 1 and the distance measuring device 4 are integrally connected to each other by using the escalator at the detecting portion 4b of the escalator. By simply tracing the handrail 7, the distance is displayed on the display unit 4a.

FIG. 3 shows an embodiment of using the brake braking distance measuring device, FIG. 4 shows a relay circuit of a control device for controlling the escalator, and FIG. 5 shows an internal configuration diagram of the distance measuring device 4. Now, when the RUN button 1a and the UP button 1b of the portable switch 1 of FIG. 1 are pressed, the control command is transmitted to the escalator control device (not shown) via a cable (not shown), and the escalator is manually moved up. And again. Similarly, when the RUN button 1a and the DN button 1c are pressed,
The descent manual operation will be performed.

For example, when the RUN button 1a and the UP button 1b shown in FIG. 1 are pressed, the RUN and UP A of the relay circuit shown in FIG.
The contact turns on and the U coil is excited, which in turn excites the brake coil and also supplies power to the drive motor,
The escalator runs up. Along with that, handrail 7
Also moves upward, so the detection unit 4b of the distance measuring device 4 is put on the handrail 7, and the fingers are released from the RUN button 1a and the UP button 1b.
When the escalator is stopped, RUN and UP A
Since the contact is turned off, the U coil is degaussed, which degausses the brake coil and also cuts off the power supply to the drive motor.

By releasing the finger from the RUN button 1a, the B contact of the RUN in the portable switch 1 shown in FIG.
Then, the power from the power supply unit 4d of the distance measuring device 4 is supplied to the display unit 4a and the calculation unit 4c through the connectors 5 and 2 and the B contact of the RUN, until the escalator is stopped after the escalator brake operation. The distance can be measured.

[0013]

As described above, according to the present invention, the distance measurement integrally connected via the connector to the portable switch which is connected to the escalator control device via the cable and can give the operation or stop command. When the stop command is sent by the portable switch, the device is powered and driven, and the distance measuring device is brought into contact with the handrail of the escalator to measure the braking distance until the actual stop after sending the stop command. As a result, the braking distance can be accurately measured in a short time.
