  On the upper side surface 11c, when the presence sensor 12 detects a track maintenance worker, the circuit board 11g controls the state before detection and changes the lighting or blinking state so that the track maintenance worker has passed the sensor range of the motion sensor 12. A patrol light 13 is provided as notification means for notification. Of course, the patrol light 13 may be configured to generate a warning sound if necessary when the human sensor 12 detects a track maintenance worker.

  The bottom surface 11d has a battery replacement back cover 11d1 that can be removed to replace the battery, and a leg support bracket that supports the base of a pair of openable and closable legs 17, 17 that can be folded and stored on the bottom surface 11d. 11d2 and 11d2 are provided.

  The right inclined surface 11e and the left inclined surface 11f, which are a pair of inclined surfaces, are respectively provided with a human sensor 12 and a vertically long slit 14a so that the detection area of the human sensor 12 does not spread in the longitudinal direction of the rail as much as possible. And a cap 14 is provided.

  Further, on the right inclined surface 11e, a power source for controlling on / off of the operation of the human sensor 12 and the patrol light 13 by controlling the supply of the power source current from the battery 11h to the human sensor 12 and the patrol light 13 as the notification means. When the switch 15 and the motion sensor 12 detect the track maintenance worker and the patrol light 13 is turned on or blinking to notify the track maintenance worker detection, the motion sensor 12 returns to the state where the track maintenance worker is not detected. A reset switch 16 is provided. The power switch 15 is a swing switch that swings on and off in a seesaw manner, while the reset switch 16 is a push switch that returns when pressed by a contracted spring (not shown). It is comprised by.

  The circuit board 11g is operated by supplying a power source current from the battery 11h to the human sensor 12 when the power switch 15 is turned on, and stops supplying the power source current to the human sensor 12 when the power switch 15 is turned off. Control. In addition, when the human sensor 12 detects a track maintenance worker, the circuit board 11g supplies a power supply current from the battery 11h to the patrol light 13 to light or blink, and notifies the track worker detection, and the patrol light 13 is turned on or flashing. When the reset switch 16 is pressed during the operation, the human sensor 12 controls to return to the state where the track maintenance worker is not detected.

  Each of the human sensors 12 and 12 is a known sensor such as a pyroelectric infrared sensor. When the track worker moves in the sensor area SA of the human sensor 12 or 12, the distribution of the amount of infrared energy changes. It detects that the track maintenance worker has passed due to the change, and is provided on each of the right inclined surface 11e and the left inclined surface 11f, which are the pair of inclined surfaces of the warning lamp main body 11, as described above. When a track maintenance worker or the like is detected, the detection of the track maintenance worker or the like is output to the circuit board 11g.

  Here, the human sensors 12 and 12 are provided with a cap 14 having a vertically long slit 14a so that the detection area does not expand in the longitudinal direction of the rail, as shown in the drawings described later.

  The patrol light 13 is also well-known, and usually emits light with extinction or weak light. When the human sensors 12 and 12 detect a track maintenance worker or the like, bright or strong light is generated by a control signal from the circuit board 11g. The human sensor 12, 12 is configured to notify that the track maintenance worker or the like has been detected, such as by emitting light or flashing, or turning on the lighting color. Of course, the patrol light 13 may be configured to further generate a warning sound when the human sensors 12 and 12 detect a track maintenance worker.

  The pair of leg portions 17 and 17 are each a short base portion 17a that is rotatably supported by the leg support fittings 11d2 and 11d2, and a standing portion that is bent 90 degrees from the base portion 17a and extends in the short side direction of the bottom surface 11d. Leg support fittings 11d2 and 11d2 which are configured by 17b and a long grounding portion 17c which is bent 90 degrees from the standing portion 17b and extends in parallel with the base portion 17a, as shown in FIG. It is provided so as to face the grounding portion 17c.

  Therefore, the warning light 1 for track maintenance according to the embodiment has a pair of leg portions 17 and 17 closed as shown in FIG. 1 to FIG. The pair of leg portions 17 and 17 are opened and protruded downward from the bottom surface 11d of the warning light main body 11 as shown in FIG. The respective grounding portions 17c and 17c can be used while being grounded on a track such as sleeper or crushed stone.

<Usage method and effect of the warning light 1 for track maintenance according to the embodiment>
Next, the usage method and effect of the track maintenance work warning lamp 1 of the embodiment configured as described above will be described.

FIG. 9 is a plan view showing an installation example of the track maintenance work warning lamp 1 according to the embodiment configured as described above.
For example, as illustrated in FIG. 9, the track maintenance work warning lights 1 according to the embodiment are respectively installed on the sleeper M1 at the front end and the sleeper M2 at the rear end, which are both ends of the work area in the longitudinal direction of the rail R. . At that time, the warning light 1 for track maintenance is the center of sleeper M1 and sleeper M2, and the right inclined surface 11e and the left inclined surface 11f, which are a pair of left and right inclined surfaces, face the left and right rails R, respectively. Install as described.

  At that time, if necessary, as shown in FIG. 8, the pair of legs 17, 17 folded from the bottom surface 11 d of the warning light main body 11 is opened, and the grounding portions 17 c of the pair of legs 17, 17 are respectively opened. You may make it install 17c on sleeper M1 and sleeper M2.

  When the power switch 15 is pushed by each warning light body 11 installed on the sleeper M1 and sleeper M2, the circuit board 11g supplies the power current from the battery 11h to the left and right human sensors 12 when the power switch 15 is turned on. Supply and operate.

  The human sensor 12 is provided on the right inclined surface 11e and the left inclined surface 11f of the warning light 1 for track maintenance work, and a cap 14 having vertically elongated slits 14a on the left and right human sensors 12 and 12, respectively. 9 is provided, as shown in FIG. 10, the warning light 1 for track maintenance is installed so that the sensor range SA from the human sensor 12 does not widen in the longitudinal direction of the rail R as shown in FIG. The track maintenance workers are detected obliquely upward from above the sleepers M1 and M2.

  Therefore, if the worker accidentally goes out of the work area between sleeper M1 and sleeper M2, which are both ends of the work area, human feeling of sleeper work warning light 1 installed with sleeper M1 and sleeper M2 The sensor 12 reacts to detect the track maintenance worker and outputs a detection signal to the circuit board 11g.

  When the human sensor 12 detects a track maintenance worker, the circuit board 11g supplies a power source current from the battery 11h to the patrol light 13 serving as a notification means, and the human sensor 12 turns the patrol light 13 on and off, etc. When the worker is not detected, the state is changed to notify that the track maintenance worker is about to pass out of the work area.

  For example, if the patrol light 13 is turned off when the human sensor 12 does not detect the track maintenance worker, the patrol light 13 is turned on or blinked when the human sensor 12 detects the track maintenance worker. Also, if the patrol light 13 is simply lit when the human sensor 12 does not detect the track maintenance worker, the patrol light 13 blinks when the human sensor 12 detects the track maintenance worker, or is brighter than when the patrol light 13 is not detected. It changes the state when the track maintenance worker is not detected, such as turning on or off, changing the lighting color, and turning on or flashing, and notifies that the track maintenance worker is about to pass outside the work area.

  Then, since the track maintenance worker can recognize that the track maintenance worker has passed out of the work area due to the change of the state of the patrol light 13, the track maintenance worker is surely prevented from accidentally going out of the work area. It is possible to reliably prevent misplacement of the work tool outside the work area.

  Thereafter, if the track maintenance worker presses the reset switch 16, the operation such as lighting or blinking of the patrol light 13 is reset, so that the human sensor 12 can return to the state where the track maintenance worker is not detected.

  Therefore, according to the warning light 1 for track maintenance work of the embodiment, the track maintenance worker can reliably prevent the track maintenance worker from accidentally going out of the work area by notifying the lighting or blinking of the patrol light 13 or the like. It is possible to reliably prevent misplacement of the work tool outside the work area.

  In particular, even if the warning light 1 for track maintenance according to the embodiment is directly installed at a low place on the orbit such as sleeper or crushed stone, the warning light main body 11 is inclined toward the center from both ends as viewed from the front. The human sensor 12 has a pair of slanted surfaces, ie, a right slanted surface 11e and a left slanted surface 11f. Since the sensor light is radiated toward, an operator can be detected reliably.

  Moreover, in the warning light 1 for track maintenance according to the embodiment, the slits 14a that are vertically long are formed on the right inclined surface 11e and the left inclined surface 11f so that the detection area of the human sensor 12 does not spread in the longitudinal direction of the rail as much as possible. Since the cap 14 having the contact point is provided, it is possible to reduce erroneous detection of the track maintenance worker by the human sensor 12, and the track maintenance work warning lights 1 are respectively installed at both ends of the track maintenance work area of the same length on the track. Even in this case, since the distance between the warning lights for track maintenance work 1 and 1 can be shortened, the burden of installing the warning lamp for track maintenance work 1 can be reduced.

  Further, in the warning light for track maintenance work 1 of the embodiment, in addition to the power switch 15, the human sensor 12 detects the track maintenance worker, and the patrol light 13 as a notification means is turned on, blinking, turned off, or the lighting color is changed. When the human sensor does not detect a track maintenance worker and when the notification is changed, the reset switch 16 is provided to reset the notification and return the human sensor 12 to a state where the track maintenance worker is not detected. Even if the presence sensor 12 detects the track maintenance worker and the patrol light 13 gives a warning, the warning state can be reset by simply pressing the reset switch 16 without turning the power switch 15 off and on. Work efficiency can be improved.

  In particular, in the warning light 1 for track maintenance according to the embodiment, the reset switch 16 and the power switch 15 are provided on the right inclined surface 11e parallel to the human sensor 12 and facing diagonally upward. 12 is provided in a range where the light of the patrol light 13 is irradiated when the patrol light 13 is turned on or flashes when the track maintenance worker is detected, so that it is easy to confirm the position of the reset switch 16 even during the night track work. Also in this respect, the work efficiency of track maintenance work can be improved.

  Moreover, in the warning light 1 for track maintenance according to the present invention, the warning light main body 11 is further provided with a pair of foldable openable / closable legs 17, 17. When it is directly installed at a low place on the track, the height can be set high, and when not in use, the pair of legs 17, 17 can be accommodated in the bottom surface 11d of the warning light main body 11.

  Therefore, the height of the human sensor 12 is increased by the height of the expanded pair of legs 17, 17 by expanding the pair of legs 17, 17 and installing them on a track such as sleeper or crushed stone. Since it can be installed at the position, it is possible to reliably detect the track maintenance worker by the human sensor 12 and reliably prevent the track maintenance worker from going out of the work area. It is possible to reliably prevent the work tool from being misplaced, and when not in use, the pair of leg portions 17 and 17 are closed and accommodated in the bottom surface 11d of the warning light main body 11, whereby the maintenance warning light 1 as a whole. Therefore, the storage space can be reduced and the transportation can be facilitated.

  In the above embodiment, the warning light body 11 is provided with the patrol light 13 as the notification means on the upper side surface 11c of the warning light body 11, but the present invention is not limited to this, and as shown in FIGS. 11 for example, the front side surface 11a or the like is perforated and an LED 13 ′ or the like as an informing means is embedded, and when the motion sensor 12 detects a track maintenance worker, the LED 13 ′ is turned on, blinking, turned off or Of course, it may be configured to notify that the track maintenance worker has passed through the sensor range of the human sensor 12 by changing the color and lighting.
