[0003] As a method of track maintenance and inspection, there is a method in which an operator walks directly on a track to an arbitrary place to perform maintenance and inspection, but as described above, since work is performed at a high place, It is extremely dangerous work. Therefore, in general, an aerial work vehicle or a tow vehicle that can position the workbench to a high place is often used.

[0004]

However, when using an aerial work vehicle or a tow vehicle, it is necessary to assemble a scaffold, to carry out disassembly work, and to carry in and out various inspection equipment near the track. It was extremely expensive and labor intensive. Further, there is also a problem that a high-altitude work vehicle and a tow vehicle cannot enter when the width of a road is narrow because the vehicle itself is large and a track inspection operation cannot be performed.
In addition, track maintenance and inspections are usually performed during periods when the monorail is not operating, so there are many midnight operations, and in conjunction with high-altitude operations, inspection work with tow trucks etc.
It was fear and mental distress for workers.

The present invention has been made in view of the above circumstances, and has as its object to maintain a track on which a monorail vehicle travels,
It is an object of the present invention to provide a track inspection work vehicle capable of easily and safely performing an inspection and removing an operator's mental pain.

Of the vehicle can be freely moved from the entrance door 11 to the rear end side of the vehicle or to the work tables 4, 4, so that the transfer from the cab to the work table 4 can be performed in the vehicle body. Thereby, the safety when moving from the cab D to the workbench 4 can be enhanced, and the mental pain and fear of the worker can be reduced. In the present embodiment, the work tables 4, 4 are arranged in the work table storage locations 2A, 2A of the vehicle body 2 so as to be flush with the side surfaces of the vehicle body.

The worktables 4 and 4 can be inspected by an inspector to perform maintenance and inspection of the track R. The worktables 4 and 4 are formed of a box surrounded by a protective fence and having an open upper part. It is installed on the pedestal 21 via the link 5 for use.

The elevating link 5 shown in this embodiment is composed of six sections 5A to 5F as shown in FIG. Among these, one of the elevating links 5B pivotally attached to the pedestal 21 has a roller 17 pivotally attached to the end thereof, and can roll on a groove rail 17 formed on the pedestal 21. still,
The rail width of the groove rail 18 is determined so that the rolling of the roller 17 is restricted at the position where the work table 4 is maximally raised.

The lifting links 5E and 5F on the side pivotally connected to the work table 4 also have the same configuration. The bottom of the hydraulic cylinder 20 is pivotally supported by the elevating link 5A, and the piston rod side is pivotally supported by the elevating link 5F. Therefore, by extending and contracting the hydraulic cylinder 20, the work table 4 can be positioned to be able to move up and down. It should be understood that the means for raising and lowering the work table 4 is not limited to the link mechanism shown in this example.

In the present embodiment, the left and right pedestals 21 are provided with slide rails 13, 14, 15, 16
1 shows a device that is slidably mounted in the vehicle width direction via a. Each of the slide rails is provided with a means such as a hydraulic cylinder (not shown) so that the worktables 4 and 4 can operate slidably. In addition to the hydraulic cylinder, a gear transmission mechanism such as a rack gear and a pinion gear may be employed.

As described above, the track inspection work vehicle 1 of this embodiment
Exemplifies that the work table 4 can not only protrude outward in the height direction, but also protrude outward in the vehicle width direction.

The suspension portion 3 is fixed to the upper surface of the vehicle body portion 2 through front and rear connecting portions 9 and 9. Is connected to the traveling wheels 6 running on the horizontal plane of the track R via the speed reducer 19. In addition, the guide wheels 8 and 8 and the auxiliary wheels 1 that slide on the vertical surface of the track R in order to prevent shaking such as roll and pitching during traveling.
