Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a track-and-land work vehicle capable of running on railroad rails (hereinafter simply referred to as "rails") laid on tracks and on roads. The invention also relates to a reflector device for a track and land working vehicle. 2. Description of the Related Art In the case of performing maintenance and inspection of a trolley wire and various facilities installed along a track, a so-called track-and-ground work vehicle is often used. This track-and-land work vehicle is configured based on a vehicle running on a road, such as a truck, and has a vehicle body with a boom that can freely move up and down, turning operation, etc. (Track running wheels). [0003] The iron wheels can be freely extended and stored in the vehicle body. When traveling on rails, the iron wheels are extended, and when traveling on roads, they are retracted. In such a track-and-land work vehicle, it is possible to quickly arrive at the work site by traveling on the road near the work site and traveling on the rail from near the work site to the work site. . By raising and lowering and turning the boom, etc., it is possible to easily perform high-altitude work around the track. [0004] Even when traveling on rails by means of iron wheels, the traveling braking of the work vehicle is performed in the same manner as the braking operation when traveling on a normal road. The red brake light is turned on, and if the headlight is turned on at night, the red tail light is also turned on. [0005] As described above, when the red light of the track-and-land work vehicle is turned on, it may be erroneously recognized as a red signal of a traffic light on the track, and may hinder the operation of other railway vehicles. Therefore, in order to prevent this possibility, a switch that shuts off an electric circuit to a brake light, a tail light, and the like when an iron wheel is overhanging is provided so that a light that may cause a misperception during track running is not turned on. It is possible. [0006] Also, on the rear end face of a vehicle traveling on a public road,
It is obligatory to provide a red reflector in addition to the above brake lights and tail lights. Therefore, not only when the brake light or the like is turned on as described above, but also when the light of the headlight of the train or the illumination for work is reflected on the reflector, there is a possibility that the signal is erroneously recognized as a red signal. Therefore, in order to prevent such an erroneous recognition, it is conceivable to provide a cover for covering the front surface of the reflector, and when performing work on a track, an operator may manually cover the reflector with the cover. [0007] However, if the worker forgets to remove the cover when traveling on a public road after the work on the track is completed, the presence of the own vehicle in the following vehicle is determined by the reflection of the reflector. It is not possible to make them aware, which is not only unfavorable for safety but also against laws and regulations. [0008] The present invention has been made in view of such a problem, and does not reflect light that is erroneously recognized as a red light when a track-and-land work vehicle travels on rails.
It is an object of the present invention to provide a reflector device of a track-and-ground work vehicle capable of surely allowing other vehicles to recognize reflected light when traveling on a public road. [0009] In order to achieve the above object, a reflector device of a track-and-land work vehicle according to the present invention is provided with a track having wheels for track running for running on rails for rails. The traveling device is provided on a track-and-rail work vehicle arranged at the rear of the vehicle body that can travel on the road, and the track traveling device is configured to move over the road and the overhang position for traveling on the railway rail. It is constructed so that it can be extended and stored between the storage position where it is performed. The track running device is provided with a reflector such that the reflection surface faces the rear of the vehicle body only when the track running device is in the storage position. [0010] In the reflector device for a track-and-land work vehicle configured as described above, when the track-and-land work vehicle accommodates the track traveling device in order to travel on the road, the reflecting surface of the reflector faces the rear of the vehicle body. As a result, the vehicle can meet the laws and regulations for traveling on public roads, and can reflect the lights of other vehicles to recognize the presence of its own vehicle (railway work vehicle). If the track-and-rail vehicle overhangs the track running device to travel on the rails, the reflection surface of the reflector does not face the rear of the vehicle body, so light reflection that may be mistaken for a red signal Does not occur. Preferred embodiments of the present invention will be described below with reference to the drawings. First, an orbital work vehicle provided with a reflector device for an orbital work vehicle 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 (road running wheels) 32 are attached to the front, rear, left and right of the vehicle body 31, respectively. A swivel base 33 that can freely turn with respect to the vehicle body 31 is attached to a front part on the vehicle body 31, and an up-and-down, telescopic boom 34 is pivotally mounted on the upper part of the swivel base 33.
At the tip of the boom 34, a worktable 35 configured to allow an operator to board is mounted. A track traveling device 10 on which iron wheels (track running wheels) 16 are freely extended (downward) and retracted (up) by an iron wheel overhanging mechanism is disposed on the right and left rear portions below the vehicle body 31. Have been. A track traveling device 40 having the same configuration is also provided on the left and right front portions below the vehicle body 31. When traveling on the rail R, the iron wheels 16, 36 are extended as shown by solid lines,
When traveling on the road, as indicated by the dashed line,
6 is stored. The track running devices 10 and 40 have the same configuration except that they have a reflector 20, which will be described in detail later, and therefore have a vehicle body 31 in addition to FIGS. Reflector 20 disposed at the rear of the vehicle
The track traveling device 10 having the following will be described. The track traveling device 10 includes a support 13 disposed on a vehicle body 31, an iron ring holding member 12 pivotally supported by a lower end of the support 13 by a pivot pin 13 a, and an iron ring holding member 12 And a telescopic cylinder 11 that swings up and down in the vertical direction. The iron wheel holding member 12 has left and right side plates, and an iron wheel 16 is rotatably supported by a pivot shaft between the two side plates. Outer side plate of the iron wheel holding member 12 (the track traveling device 10 disposed on the left side of the vehicle body)
, A reflector 20 is attached to the left side plate 12a. The reflector 20 has an L-shaped reflector mounting plate 22 having a reflector mounting surface 22a protruding outward and having a fixing surface fixed to the iron wheel holding member 12, and a reflector mounted on the reflector mounting surface 22a. And a main body 21. The reflector mounting plate 22 is mounted such that the reflector mounting surface 22a faces rearward (in the direction shown by the arrow B) in the retracted state in which the iron ring holding member 12 is swung upward as shown by the solid line in FIG. Has been. Since the reflector main body 21 is mounted on the reflector mounting surface 22a of the reflector mounting plate 22 thus mounted, the reflection surface 21a of the reflector main body 21 faces the rear of the vehicle body 31. The reflector main body 21 attached to the track-and-land work vehicle 30 is a reflector formed of a prescribed material and size in red, which is prescribed by laws and regulations. Also, the position where the reflector 20 is attached to the track traveling device 10 is a position defined by regulations. In the extended state in which the iron ring holding member 12 is swung downward as shown by a dashed line in order to travel on the rail R, the iron ring holding member 12 is moved from the retracted state by about 90 degrees.
Due to the swing, the reflection surface 21a faces downward, and cannot be seen from the rear of the track-and-land work vehicle 30. Since the track running device 10 thus configured is disposed on the right and left rear portions of the vehicle body 31, and the track running device 40 without the reflector 20 is disposed on the right and left front portions of the vehicle body 31, FIG. As shown, the reflectors 20, 20 are disposed on the left and right sides of the lower part of the vehicle body 31 when viewed from the rear of the rail and land work vehicle 30. The track and place aerial work vehicle 30 provided with the track running devices 10 and 40 first travels on a road (public road) to a railroad crossing near a work site. At this time,
Since the track running devices 10 and 40 are in the retracted position, the respective reflecting surfaces 21a of the reflectors 20 and 20 are disposed facing the rear of the vehicle body 31, and reflect light from headlights of other vehicles. By doing so, the presence of the vehicle can be recognized, so that safety on public roads can be ensured. When the vehicle travels on a public road and arrives at a railroad crossing near the work site, the work vehicle 30 is stopped so as to cross the rail R on the railroad crossing. Then, the center jack 38 attached to the lower part of the vehicle body 31 is extended and the vehicle body 31 is lifted up and then turned so as to be parallel to the rail R, and the track running devices 10 and 40 are extended and the iron wheels 16 are extended. , 36 overhang the rail R. After the iron wheels 16, 36 are overhanged, the center jack 38 is contracted to put each iron wheel 36 on the rail R. At this time, since at least the rear tire 32 abuts on the rail R, when the tire 32 is driven, the work vehicle 30 runs on the rail R. The overhang of the iron wheels 16 and 36 is detected by an unshown iron wheel overhang detection switch, and upon receiving this detection signal, the controller cuts off the power supply to the brake lights and tail lights provided at the rear end of the vehicle body 31. Therefore, when the brake is depressed, the tire 32 is braked and the work vehicle 30 is stopped. However, at this time, the red brake light is not turned on, so that the driver of another train does not mistakenly recognize a red light. Further, the reflection surface 2 of the reflector 20
1a faces the lower part of the vehicle body, and does not reflect light even if light is irradiated from behind or in front of the rail and land vehicle 30. Therefore, the signal 1a is not mistaken for a signal provided on the track. In the track running devices 10 and 40 provided in the track-and-land work vehicle 30, the retracted state is achieved by swinging upward from the state in which the iron wheels 16 and the like are extended toward the rear of the vehicle body 31. However, the configuration of the track running device 10 and the like is not limited to this. For example, the storage state may be configured by swinging upward toward the front of the vehicle body 31. With such a configuration, the reflection surface of the reflector faces upward in the storage state of the track traveling device. be able to. As described above, in the reflector device of the track and land working vehicle according to the present invention, the bridge between the overhanging position for traveling on the railroad rail and the retracted position for traveling on the road is provided. A reflector is provided on a track running device configured to be freely retractable and retractable, and the reflector has a reflecting surface facing the rear of the vehicle body only when the track running device is in a storage position. For this reason, when driving on public roads with iron wheels stored,
As a vehicle for traveling on public roads, it can satisfy the regulations and can travel safely. In addition, in a state in which the iron wheels are overhanging and traveling on the rail, the train driver, station staff, and the like do not mistakenly recognize that the red signal for the track is lit, and confusion on the track does not occur.
