TECHNICAL FIELD OF THE INVENTION
The present invention relates to a track work vehicle capable of traveling on railroad rails, and more particularly to mounting a trackworking vehicle on railroad rails or when a railroad work vehicle derails from a railroad rail. The present invention relates to a vehicle body moving device or a vehicle body moving tool for prompt recovery.
[0002]
[Prior art]
When performing maintenance and inspection of trolley wires and various facilities installed along railway rails, so-called track work vehicles (hereinafter, also referred to as “rail work vehicles”) that can run on railway rails are used. The track work vehicle is often used, and a track work vehicle capable of traveling on a general road is often used as the track work vehicle. This track-and-land work vehicle is configured on the basis of a vehicle running on a road such as a truck, and a work table attached to a tip of a boom that can freely move up and down, turns, and the like is mounted on the body at a desired height. An aerial work device configured to be able to be moved is provided, and a track running wheel (hereinafter, referred to as an iron wheel) for running on a rail for rail (track) is provided at a lower portion of the vehicle body. I have.
[0003]
In such a track-and-land work vehicle, the vehicle travels on a road by using tires (road running wheels) to a position near the work site, and travels on a railway rail from a position near the work site to move to the work site. Thereby, it is possible to quickly arrive at the work site, and to perform high-altitude work around the railroad rail at the work site.
[0004]
In such a track-and-land work vehicle, outrigger jacks are generally provided on the front, rear, left and right sides of the vehicle body in order to stably support the vehicle body when working at a high place. The outrigger jack is configured to be extendable and contractible in the left and right direction with respect to the vehicle body, and extends vertically to contact the ground, lift the tires and iron wheels, and act on the moment acting in the direction that causes the vehicle body to fall when the boom is extended. It is configured to stably support the vehicle body. Therefore, at the time of work, the jack is grounded in advance, and the work is performed after the vehicle body is stabilized.
[0005]
However, at the end of the work, the vehicle body may be slightly displaced in the left-right direction from the start of the work due to vibrations during the work or the like, and if the outrigger jack is stored (reduced) as it is, the iron wheel comes off from the rail for railway (derailing). Do). In such a case, the outrigger jack is extended vertically to lift the tires and the iron wheels, and then the jacks are simultaneously expanded and contracted in the lateral direction of the vehicle body in each jack, thereby moving the vehicle body to the left and right. Was adjusted to match the position of the railway rail.
[0006]
[Problems to be solved by the invention]
However, some track-and-rail work vehicles cannot equip the body with a jack slide mechanism or the like due to weight restrictions or the like. Since the iron wheel cannot be moved in the left-right direction, the iron wheel cannot be positioned again on the railroad rail. Therefore, in order to prevent derailment during work, it is necessary to control the amount of expansion and contraction of the jack in the vertical direction so as to control the flange portion of the iron ring so as to be engaged with the railroad rail. there were. In addition, since it is necessary to rotate the car body horizontally at the time of iron wheel loading when transitioning from road running to track running, it is difficult to align the position of the iron wheel and the rail, and if there is any deviation, the turntable must be reinstalled There was also a problem that it did not become. Furthermore, since the vertical lifting type track-and-rail work vehicle does not require a special jack, a derailment recovery device using a jack slide mechanism cannot be configured.
[0007]
The present invention has been made in view of such a problem, and an outrigger jack or the like is provided with a device for moving the vehicle body in the left-right direction by adding a device for moving the vehicle body to a turntable in a track and land working vehicle. And a vehicle moving device for a track-and-ground working vehicle that is capable of mounting the vehicle body on a track in a stable supported state while being a simple mechanism even in a case where the slide mechanism of the jack cannot be used due to a failure of the vehicle, or a failure, etc. It is intended to provide a vehicle moving device. It is another object of the present invention to improve the workability of mounting wheels for track running on a rail for rails when shifting from road running to track running.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the body moving device of the track working vehicle of the present invention has one end fixed to the body of the track working vehicle having iron wheels capable of traveling on the track, and the other end vertically extending from the lower part of the body. A turntable that extends and contracts, has the other end extended, is grounded on the track surface, and horizontally rotates the vehicle body with the iron wheel disposed on the vehicle body floating from the track surface; and A vehicle body supporting member provided on a lower surface and having a moving means for slidingly moving the vehicle body with respect to the track surface in a state of being grounded on the track surface by sliding with respect to the turntable , thereby stably supporting the vehicle body. It is possible to perform turning and sliding movement in the state of being turned.
[0009]
Further, the vehicle body moving device of the track working vehicle according to the present invention for achieving the above object is a vehicle body moving device used in a track working vehicle having the turntable, and is provided on a track surface vertically below the turntable. by fixing the base member to be mounted, rolling the chassis is placed on a movable body that is slidably supported relative to the base member is composed of the movable member and a driving means for sliding in body Can be swiveled and slid in a state of stable support.
[0010]
When such a track work vehicle is configured as a track and land work vehicle capable of traveling on a track and on a road, the vehicle moving device of the track work vehicle is used as follows. When the track-and-land work vehicle is mounted on a track, the track-and-land work vehicle is stopped at a crossing or the like so that the center line between the left and right tracks and the center of the turntable are aligned. Then, the turntable provided at the lower part of the body of the track-and-land work vehicle is directed vertically downward, the body support member attached to the lower surface of the turntable comes into contact with the track surface, and the tires and the iron wheels float above the track surface. Overhang. Then, the turntable is rotated horizontally with respect to the track surface, and the track-and-land work vehicle is directed in the track direction. At this time, if the position of the iron wheel is deviated from the position of the railway rail, the vehicle body is slid in a desired direction by the moving means provided on the vehicle body support member, and the position of the iron wheel with respect to the railway rail is corrected. Then, the turntable is reduced, and the track-and-land work vehicle is placed on the track.
[0011]
When a track work vehicle (not necessarily a track-and-land work vehicle) is derailed due to vibration or the like while working or running on a track, spread a simple laying board etc. between the tracks in the vertical direction of the turntable, and After turning the turntable vertically downward, the vehicle body support member attached to the lower surface of the turntable comes into contact with the track surface, and further stretches until the iron wheel rises above the track surface. Then, the vehicle body can be slid by the moving means provided on the vehicle body support member and the iron wheel of the track work vehicle can be placed on the track in the same manner as described above.
In addition, the vehicle body moving tool of the track work vehicle according to the present invention has a vehicle body supporting member having a moving means of the vehicle body moving device formed separately from the turntable, and the lower surface and the track surface of the turntable during use. The operation is exactly the same as that of the vehicle body moving device, and the description thereof is omitted.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. First, an orbital work vehicle equipped with a vehicle moving device according to the present invention will be described with reference to FIG.
The track-and-rail working vehicle 30 is configured based on a truck running on a road. For this reason, tires (road running wheels) 32F and 32R are attached to the front, rear, left and right of the vehicle body 31, respectively. At the rear of the vehicle body 31, a turntable 33 that can freely turn with respect to the vehicle body 31 is attached. An up-and-down, telescopic boom 34 is pivotally mounted on the upper part of the swivel base 33, and a work table 35 is attached to the tip of the boom 34.
[0013]
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 by arrows. In the iron wheel overhanging mechanism, the horizontal pitch of the iron wheel 36 is fixed in accordance with the pitch of two railway rails (tracks) (hereinafter referred to as “rails”) R.
As shown in FIG. 3, the iron ring overhanging mechanism includes a support 13 disposed on a vehicle body 31, an iron ring holding member 12 provided at a lower end of the support 13 so as to be swingable by a pivot pin, and The lifting and lowering cylinder 11 is configured to swing the iron wheel holding member 12 in the vertical direction by operation. The iron wheel 36 is rotatably attached to the iron wheel holding member 12 by a pivot pin.
[0014]
As shown in FIG. 4, a center jack 21 having a pair of left and right cylinders and a pair of left and right cylinder jacks are attached to the center of the lower part of the vehicle body 31, as shown in FIG. A turntable 20 having a race member 22 for turning the vehicle body 31 so as to be parallel to the rail R is provided so as to be able to expand and contract vertically downward. Further, on the lower surface of the turntable 20, a pedestal member 23 that contacts the raceway surface when the turntable 20 is extended and supports the vehicle body 31, and the turntable 20 is placed on the pedestal member 23. A movable member 24 slidably supported with respect to 23 is fixedly provided on the turntable 20.
[0015]
As shown in FIG. 5, the pedestal member 23 is provided with a screw in the longitudinal direction of the pedestal member 23, that is, in a direction perpendicular to the central axis of the pedestal member 31, as a mechanism for slidingly moving the vehicle body 31 together with the turntable 20. A position adjusting screw rod 25 having a groove is rotatably supported by a shaft. A handle 26 for driving shaft rotation is attached to one end of the screw rod 25. A part of the movable member 24 fits into the thread groove, and is configured to be able to slide the movable member 24 right and left with the rotation of the screw rod 25.
[0016]
The track-and-rail work vehicle 30 configured as described above first travels on the road to a railroad crossing near the work site, moves across the rail R at the railroad crossing, and the turning platform 20 is located at the center between the rails. The work vehicle 30 is stopped so as to be positioned. Alternatively, a work board 30 may be stopped so as to cross a rail R at a desired place other than a railroad crossing, by preparing a floor board for a simple railroad crossing. The stopped work vehicle 30 extends a pair of left and right center jacks 21 provided on the turntable 20 in the lower center of the vehicle body 31 in a vertically downward direction.
[0017]
Then, the pedestal member 23 attached to the lower surface of the turntable 20 contacts the track surface. Further, as the two cylinders 21 are extended, the entire weight of the vehicle body 31 is applied to the pedestal member 23, and the vehicle body 31 comes to float from the track surface. In this state, the vehicle body 31 is turned around the center jack 21 until it becomes parallel to the rail R. In order to perform this turning on the turning table 20, a race member 22 is disposed between the turning table 20 and the pedestal member 23, and the turning of the vehicle body 31 is enabled by applying a turning force equivalent to rolling friction force. I have.
[0018]
With the vehicle body 31 being parallel to the rail R, the iron wheels 36 attached to the front, rear, left and right of the vehicle body 31 are extended, and the center jack 21 is reduced to put each iron wheel 36 on the rail R. At this time, if the stop position of the track-and-rail work vehicle 30 is not good, the positions of the iron wheels 36 and the rails R cannot be accurately adjusted, and if the center jack 21 is reduced as it is, there is a possibility that the wheels will fall off. However, in the present invention, the race member 22 is fixedly disposed on a movable body 24 slidably supported on a pedestal member 23, and is directly connected to the screw rod 25 at one end of the pedestal member 23. By operating the handle 26 attached to the movable member 24, the screw rod 25 can be rotated, and the movable body 24 can be slid. As a result, the vehicle body 31 can move on the pedestal member 23 without correcting the stop position of the vehicle body 31, and the positions of the iron wheels 36 and the rails R can be adjusted.
[0019]
Further, as another method of using the vehicle body moving device of the track-and-rail working vehicle 30 configured as described above, the vehicle moves on the rail R to the work site, and when working at the work site, vibrations or the like occur. There are cases such as when the wheel was derailed. In such a case, a vertical lifting type railroad vehicle that does not require a conventional jack or a track-and-rail work vehicle that has a jack but cannot be equipped with a jack slide device due to weight restrictions must recover from derailment by itself. Can not.
[0020]
In such a case, in the track-and-rail working vehicle 30 according to the present embodiment, first, a laying board for a simple level crossing is laid around the rail R so that the ground surface and the track surface are at the same height. Thereafter, the turntable 20 disposed in the center of the lower part of the vehicle body 31 is extended vertically downward, the pedestal member 23 is grounded, and the vehicle body 31 floats. Thereafter, the vehicle body 31 can be slid by the same method as described above, and the iron wheels 36 can be adjusted to the positions of the rails R, and the vehicle body 31 can be mounted on the rails R again.
[0021]
In the above, the vehicle body supporting member having the moving means for slidingly moving the vehicle body 31 is integrally formed with the turntable 20, and the vehicle body moving device of the track work vehicle fixed to the vehicle body 31 at all times has been described. The vehicle body supporting member having the means can be configured separately from the turntable 20 to form a vehicle moving device. As shown in FIG. 5, such a vehicle moving tool is connected to a pedestal member 23 placed on a track surface, a movable body 24 slidably supported on the pedestal member 23, and connected to the movable body 24. It is composed of a screw rod 25 for transmitting a rotational driving force to the movable body 24 and a handle 26 for applying a rotational force to the screw rod 25.
[0022]
The vehicle moving device of the track-and-rail working vehicle 30 configured as described above is used as follows. The work vehicle 30 moved to a railroad crossing near the work site or the like is stopped so as to cross the rail R on the railroad crossing and the turntable 20 is located at the center between the tracks. The stopped work vehicle 30 extends the turntable 20 in the lower center of the vehicle body 31 vertically downward. At this time, the vehicle moving tool is placed between the turning table 20 and the track surface, and the turning table 20 is placed on the center of the movable body 24 of the vehicle moving tool. When the amount of extension of the turntable 20 is further increased, the vehicle body 31 rises from the track surface. Thereafter, the car body 31 is turned until it becomes parallel to the rail R by rotating the turntable 20 about the center jack 21. Thereafter, the vehicle body 31 can be slid as described above, and the iron wheel can be accurately placed on the rail R.
