JPH01109165A - Side sliding door opening/closing device for monorail cars - Google Patents

Abstract

PURPOSE:To prevent the falling of a passenger outside a car due to erroneous operation of a sliding door by providing a device for detecting the existence of a platform on each side of a monorail car and opening/closing only the sliding doors on the platform side based on each detected signal. CONSTITUTION:The sliding door closure safeguard contact 2 of a sliding door opening/closing circuit 1 is kept OFF by means of a sliding door closure safeguard signal 3 at the time of the traveling of a monorail car. When a monorail car arrives at a platform, out of each pair of platform detecting devices 6, 8 and 7, 9 which are provided on both sides of the monorail car respectively, one pair of detecting devices positioned on the platform side, e.g., 6, 8 are operated and one platform contact 10 is turned ON. Hence, as one sliding door opening/closing switch 4 is operated, one solenoid valve 12 is turned ON, opening one sliding door. At this time, since the other platform contact 11 is kept OFF, the other sliding door will not be erroneously opened.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a monorail car that operates on an elevated track, and the side sliding door on the side opposite to the platform opens due to an erroneous operation by the conductor while the car is stopped at a station, allowing one passenger to exit the car. This invention relates to a side sliding door opening/closing device for monorail cars to prevent falling accidents.

[Conventional technology]

The conventional side sliding door opening/closing device detects the vehicle speed when the monorail car is running at 5 blHQ per hour.

Side sliding door opening/closing - This is a system that blocks the road and prevents the side sliding door from opening even if the conductor accidentally operates the opening/closing switch.
When the train is stopped at a station, etc., the sliding doors on either side can be opened and closed by the conductor, and there is a risk that the sliding doors on either side of the platform may open due to incorrect operation. No consideration was given to this type of device.
No. 684 etc. are mentioned.

[Problem that the invention seeks to solve]

The above conventional technology is a system that makes it impossible to open and close the side sliding doors only when the monorail car is running, and when the monorail car is stopped at a station etc.
The sliding doors on either side can be opened and closed by the conductor's operation, and no consideration has been given to the possibility that the sliding doors on either side of the main platform may open due to the conductor's malfunction. There was a risk that passengers would fall outside the vehicle (approximately 1 oll above the ground).

An object of the present invention is to enable the conductor to open and close only the side sliding door on the platform side by detecting the position of the platform when the train is stopped, thereby preventing erroneous operation.

[Means for solving interlayer points]

The above purpose is to detect the stopping position II (the vehicle is stopped within the range of the platform) and the presence or absence of the platform using a platform detection device installed on both front sides of the monoseal car, and to send the signals to open and close the side sliding doors. Enter after the circuit door closing security (during door opening interlock while driving),
While parked and.

Only the side sliding door on the platform side can be opened and closed by a switch operated by the conductor.

[For production]

A platform is detected in the height range of the platform end face near the edge of the kite on the side of the lower underframe of the driver's cabin side opening door of both leading cars!
[111 is installed and the vehicle enters the station.]

When the vehicle is stopped, each platform detection device (4 units) detects the distance between the platform end face and the vehicle, usually 100 to 30
However, if two units on the same side of the vehicle simultaneously detect this, it means that there is a platform on that side that is longer than the vehicle, and this signal is sent to the side sliding door opening/closing circuit. Door closing security (side sliding door opening/closing interlock while driving)
The train is parked within the range of the platform, and only the side sliding door on the platform side can be opened and closed using the side sliding door switch operated by the conductor.
Even if you accidentally operate the side sliding door open/close switch on the side opposite to the platform, the side sliding door will no longer open or close incorrectly.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

This will be explained with reference to Figure II3. Figure 1 shows a block diagram of the side sliding door opening/closing device system for monoseal cars.

At the side sliding door opening/closing opening at, the door closing safety contact 2 is not configured by the door closing safety signal 3 when the vehicle is running, but remains open even if the l side sliding door opening/closing switch 4 is operated. The sliding door cannot be opened or closed. When the mono sticker car 14 enters the station while running on the track girder and stops at the area S in the middle of the platform, the first platform detection device 6
The third platform detecting device 8 detects the end face of the platform fat, and the first platform contact is configured based on the signal. Then the conductor asked the 1st side sliding door open/close switch 4.
When operated, the contact point of the platform on the 1st side is activated, which turns on the solenoid valve ν for the sliding door on the 1st side (platform side), and the sliding door on the 1st side (platform side) opens.

Even if the conductor accidentally operates the side sliding door open/close switch 5 on the side opposite to the platform, the 2nd platform detection device 7 and the 4th platform detection device 9 will not detect the platform, so the 2nd platform contact 11 is not configured, and the second side sliding door solenoid valve 13. is not turned on and the sliding door on the second side does not open.The relationship between W1 and W1 is shown in FIG. 2 in a plan view and in FIG. 3 in a sectional view.

As shown in 2, when the 1 mono sticker car 14 is stopped at a station at a high place, even if the conductor accidentally operates the side sliding door open/close switch on the side opposite to the platform, the side sliding door will not open and one passenger will not be able to exit the car. It is possible to prevent falling accidents and perform safe heavy vehicle operation.

〔Effect of the invention〕

According to the present invention, when a mono-sealed car that operates on an elevated platform stops at an elevated station, even if the conductor accidentally moves out of the platform range or operates the side door opening/closing switch on the side opposite to the platform, The side sliding door prevents a single passenger from falling out of the car, resulting in safer Morle operation.
It has a driving effect.
