Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is intended to ensure the safety of workers during maintenance work on tracks for running vehicles, especially tracks in garages, operating areas, etc., and to prevent vehicle accidents due to uncompleted safety work. This relates to security devices.

BACKGROUND OF THE INVENTION During the operation of railway vehicles, daily track inspections and simple work are carried out not only in depots and operating areas, but also on railway main tracks. Conventionally, when starting an inspection or work, a worker would check the working time using a driving schedule, and then use a communication device to notify the vehicle driver of the start of the inspection or work, thereby making it easier for both the worker and the driver to communicate. Safety is maintained by taking precautions. This is mentally taxing for both parties.
There is also a possibility that misunderstandings may occur. Furthermore, when the vehicle is operated unmanned, safety is ensured only by the worker himself, so it is desirable to have a warning display that makes it extremely easy to know about dangerous situations. In addition, since it is difficult to identify the track on the spot on complex tracks such as garages and operating areas, it is desirable to automatically display a warning display that clearly identifies the track on which a vehicle is approaching. Sometimes, in response to this warning display, it is necessary to prevent vehicles from entering due to reasons such as unfinished work, and this must also be considered.

The present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to provide a vehicle track safety device with a simple structure that provides an extremely easy-to-understand warning display to workers and the like.

As a means of warning, flashing the vehicle's headlights and sounding the horn may be done automatically or manually, but dangerous tracks can be more easily and reliably identified by placing the warning display on the track side. . Therefore, the present invention
Warning devices with a large number of visible indicator lights are placed along each track of the track equipment equipped with signal equipment to control whether or not a vehicle can proceed onto the track. The present invention is configured such that only the warning devices disposed on the corresponding track, that is, only the warning devices arranged in a line, issue a warning in conjunction with a signal issued from the signal equipment to the track corresponding to the progress of the vehicle. An emergency stop input device may be attached along the vehicle track so that a worker or the like who, upon receiving a warning from the warning device, determines that it is inconvenient for the vehicle to enter the vehicle due to unfinished work or the like can easily manually operate the vehicle. Further, the warning device may include only an indicator light, or an indicator light and a warning device.

Hereinafter, one embodiment of the present invention will be explained with reference to the drawings. Figure 1 is a plan view of a garage located close to the main track, where 1a and 1b are shown on the main track, and dotted line 2
The area indicated by is the garage area, within which there is a factory 3 and a vehicle inspection yard 4, as well as many parking lines. In order to allow a vehicle to enter the vehicle inspection area, a course is set, for example, as shown by thick line 5.
At the same time as the signal equipment sends a signal allowing the vehicle to proceed, the warning device is activated and the indicator light indicated by the X mark 7 is turned on. That is, since many indicator lights are lit along the track on which the vehicle is traveling, the shape of the track is represented by the light. In the part shown at 5', no signal is sent to allow the vehicle to proceed, but an indicator light is turned on to prevent danger in the event the vehicle overruns.

When moving a vehicle from the detention area to the main line,
A course is set as shown by a thick line 6, and at the same time as the signal equipment sends a signal allowing the vehicle to proceed, an indicator light 7 indicated by an X mark is lit along the course 6, as described above. 8 indicates indicator lights installed along the track, which are not lit. 9 is controlled by the signal equipment so that a nearby alarm device that is set on a course will automatically emit a warning sound.

Figure 2 is a cross-sectional view of the track showing the arrangement of indicator lights and warning horns, 11 is the track rail, 12 is the sleeper, 1
3 is a track bed ballast, 7a to 7d are indicator lights attached to the upper surface of the railroad ties, and 9 is a warning horn attached to a pillar. 14a to 14d are push-button switches installed along the track as emergency stop input devices for the vehicle. By pressing this switch, the signal equipment directly issues a signal to stop the vehicle, or the vehicle powers off. In the case of a power system, it sends a signal to the power control system, which is part of the railway system, to cut off the power supply to the overhead contact line, which is the power supply source, and stop the train. If the warning display appears and the vehicle cannot continue to drive because the work is not completed, or if it will take some time for the worker to leave, the worker can operate this switch to stop the vehicle from entering. can be prevented.

As described above, according to the present invention, a large number of warning devices are provided along the track, and among these warning devices, only one of the warning devices is provided along the track to which the signal allowing the vehicle to proceed is sent from the signal equipment. warning device,
Since it is activated by the signal from the signal equipment, even in places where many tracks are arranged in a complicated manner, such as in a garage or operation area, the many warning devices installed along the tracks can alert the vehicle. The advancing trajectory can be clearly recognized. If work continues on the track on which the vehicle is traveling even after receiving a warning, or if workers cannot evacuate in time, the operator can easily activate the emergency stop input device, which is installed in large numbers along the track. The level of security can be increased by adding equipment that stops the vehicle's progress based on input and prevents entry. The present invention can be implemented by adding simple functions to the currently commonly used signaling equipment, and has the excellent effect of ensuring safe work with an extremely simple configuration. This is expected to be particularly effective when the vehicle is unmanned.
