When the work vehicle travels on rails, the iron wheels protrude, and when traveling on a road, the iron wheels protrude. Is stored. In such a track-and-ground work vehicle, the vehicle travels on a road to near the work site, and travels on a rail from a railroad crossing near the work site to the work site.

[0004] Normally, when performing work on rails, lights such as a yellow rotating light provided on a vehicle body are turned on to call attention to surrounding workers and the like. This light can be turned on or off by operating an operation switch (light lighting means) provided on the vehicle body.

[0005]

[Problems to be solved by the invention]

 However, if the operation of turning on and off the lights is to be operated by the operation switches, if the lights are turned on when working on the rails, and the workers forget to turn off the lights after the work, the vehicle is moved from the rails to the road. The vehicle will be driven on roads with the yellow rotating lights and other lights turned on, and it will be mistaken as a road maintenance work vehicle. It is a violation.

[0006] The present invention has been made in view of such a problem, and has a simple configuration so that a lamp used during work on a vehicle body does not turn on when a track and land work vehicle travels on a road. It is an object of the present invention to provide a light control system for a railway orbiting work vehicle.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the light control system of the track-and-land work vehicle of the present invention includes a track running wheel that is provided on a vehicle body so as to extend and retract so as to run on a rail, and the track running wheel. Track running wheel overhang detection means for detecting that the vehicle wheels are overhanging; a lamp provided on the vehicle body and used when the vehicle body is working on railroad rails; A lamp lighting means for turning on and off, and a lighting control means for restricting the light from turning on unless the track running wheel overhang detection means detects that the track running wheel is overhanging. Consists of

In a track-and-rail working vehicle employing such a light control system, the lighting control means controls the lighting of the light on the road irrespective of the operation of the light lighting means. The lamp can be turned on according to the operation of the lamp lighting means when it is issued.

In addition, the lighting control system of the track-and-land work vehicle is extended to run on the rails for rails, and the track-running wheels provided so as to be retractable and the storage of the track-running wheels are detected. A track running wheel storage detecting means, a light provided on the vehicle body and used when the vehicle is working on a railroad rail, and a lamp light provided on the vehicle body to turn on and off the work light And lighting control means for controlling lighting of the lamp by a detection signal from the track running wheel storage detecting means regardless of operation of the lamp lighting means.

[0010] In a track-and-land work vehicle employing such a light control system, when the track running wheels are stored for running on the road, the track running wheel storage detecting means is used for the track running wheel storage detecting means. The storage of the wheels is detected, and based on the detection signal, the lighting control means controls the lighting of the lamp used during the work regardless of the operation of the lighting device.

[0011] Thus, when the track-and-land work vehicle travels on the road, the lamp used during the work is not turned on and is not mistaken for the road maintenance work vehicle.

[0012]

[Embodiment of the invention]

 Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. First, a track-and-land work vehicle equipped with the light control system according to the present invention will be described with reference to FIG. The track-and-land work vehicle 30 is configured based on a truck running on a road. For this reason, tires 32 are attached to the front, rear, left and right of the vehicle body 31, respectively. A swivel 33 attached to the front of the vehicle body 31 is pivotally mounted with a boom 34 having a worktable 35 attached to the tip thereof and capable of freely moving up and down and expanding and contracting.

Iron wheels (track running wheels) 36 are attached to the front and rear and left and right sides of the vehicle body 31, respectively, so as to extend (down) and retract (up) by an iron wheel overhanging mechanism. As shown in FIG. 2, the iron ring overhanging mechanism includes a column 39 disposed on the vehicle body 31, an iron ring holding member 37 provided at the lower end of the column 39 so as to be swingable by a pivot pin or 39a. The telescopic cylinder 40 is configured to swing the iron wheel holding member 37 in the vertical direction by operation.

An iron wheel 36 is rotatably attached to the iron wheel holding member 37 by a pivot pin 37a, and an iron ring overhang detection switch (wheel running wheel overhang detection means) 22 is attached to a lower portion of the column 39. I have. A limit switch is used as the iron-ring overhang detection switch 22. When the iron-ring holding member 37 is lowered by the extension operation of the telescopic cylinder 40, the rear end of the iron-ring holding member 37 and the cam 22a of the iron-ring overhang detection switch 22 are moved. When the contact is made, the limit switch is closed, and the relay solenoid 211 of the relay switch (lighting control means) 21 to be described in detail later is excited.

On the other hand, above the cabin 41 in front of the vehicle body, a yellow rotating light (light) 16 is provided so as to be detachable. As shown in FIG. 1, the yellow rotating light (light) 16 is supplied with power from a vehicle battery B, and is normally turned on or off by operating a work light switch (light lighting means) 13 provided in the cabin 41. It is configured to blink.

The relay switch (lighting control means) 21 is composed of a relay solenoid 211 and a relay contact 212. When a current flows through the relay solenoid 211 to be in an excited state, the relay contact 212 is closed and the relay solenoid 212 is closed. When 211 is de-energized, relay contact 212 is opened. The relay solenoid 211 is inserted in series with the iron ring overhang detection switch 22 in a circuit connected to the vehicle battery B, and the relay contact 212 connects the work light switch (light lighting means) 13 and the yellow rotating light (light) 16. When the relay solenoid 211 is in the excited state, the relay contact 212 is closed, and the wiring between the work light switch (light lighting means) 13 and the yellow rotating light (light) is connected. It is designed to communicate.

In the rail-road aerial work vehicle 30 configured as described above, first, on the rail R near the work site, each iron wheel 36 is lowered downward as shown by a solid line in FIG. It is in a protruding state. In this state, since the iron ring overhang detection switch 22 is in the closed state, the relay solenoid 211 of the relay switch 21 is in the excited state.

Therefore, the contact 212 disposed between the work light switch 13 and the yellow rotary light 16 is in a closed state, and can be turned on in response to the operation of the work light switch 13. The worker operates the work light switch 13 and operates the yellow rotating light 16 on the rail R when the trolley wire and various facilities are to be maintained and inspected on the rail R using the track and place aerial work vehicle 30. Lights or flashes to alert surrounding workers, such as in front of or behind the vehicle.

After the work on the rail R is completed, the vehicle travels on the rail R and is moved to a railroad crossing near the work site, and the work vehicle 30 is stopped at the railroad crossing. The center jack 38 is extended downward to lift the vehicle body 31 itself. Then, the vehicle body 31 is turned so as to be parallel to the road, the iron wheel 36 is stored, and the tire 32 is driven on the road.

Each iron wheel 36 is stored while being lifted upward. In the state where the iron wheels 36 are stored, the iron wheel overhang detection switch 22 is opened. Then, the relay solenoid 211 is de-energized, and the contact 212 disposed between the work light switch 13 and the yellow rotary light 16 is opened. Therefore, regardless of the operation of the work light switch 13, the yellow rotating light 16 is turned off.

According to the track-and-land work vehicle 30 provided with the light control system configured as described above, when the vehicle is running on the rail R, the work light switch 13 is operated to turn the yellow rotating light 16 or the like on. The lighting can be turned on, and the lighting such as the yellow rotating light 16 will not be turned on on the road regardless of the operation of the work light switch 13.

As another embodiment, instead of the iron ring overhang detection switch 22, an iron wheel storage detection switch that detects that an iron wheel has been stored may be used. In this case, the relay switch 21 detects that the iron wheel is retracted, and energizes the relay solenoid 211. When the relay solenoid 211 is energized, the contact point 212 between the work light switch 13 and the yellow rotary light 16 is opened. Let it be done.

With the above configuration, when the vehicle is running on the rail R, the relay solenoid 211 is in a non-excited state and the contact point 212 is in a closed state. However, on the road, the iron wheel storage switch detects that the iron wheel has been retracted, excites the relay solenoid 211, and the contact 212 is opened. Irrespective of the operation of 13, the lighting of the yellow rotary light 16 is regulated.

In the above-described embodiment, the lamp 16 is a yellow rotating light, but an indicator light for displaying work, such as an indicator light in which LED lamps are assembled and blinked. However, it is sufficient if the lamp is used only during work, such as a work light that illuminates the vicinity of the vehicle body during work.

[0025]

[Effect of the invention]

 As described above, in the light control system for a track-and-rail work vehicle according to the present invention, when the iron wheels are overhanging and running on the rail, the light such as the yellow rotating light can be turned on by operating the light lighting means. When the vehicle is running on the road with the iron wheels stowed, the light used during the work is turned off regardless of the operation of the light lighting means, so if you forget to turn off the light lighting means and work on the road The lights used for lighting the roads will not be mistaken as road maintenance vehicles, nor will they violate the Road Transport Vehicle Law. Also, in a track running vehicle employing a light control system using a track running wheel storage detecting means, which is one of the embodiments of the present invention, if the light lighting means is operated in the lighting state, If the track wheels are not completely retracted when they are stored, the lights used during the work will remain lit, so the worker must drive on the road without completely storing the track wheels. Can be prevented beforehand, and the safety of driving on the road can be ensured.
