The trackbed 2 is made of rails 4, 4, i.e., the crushed stones are further crushed by the vibrations caused by the train passing on the tracks, the weight of the train, etc., or are trampled and hardened, and the original purpose is The support of sleepers, which is
Since functions such as maintaining the track and improving drainage performance deteriorate, it is necessary to replace it at predetermined intervals.

Conventionally, the trackbed replacement work described above has been carried out in the following manner.

As shown in FIGS. 6 and 7, the belt conveyor 5 is installed approximately at right angles to the track bed 2' on which replacement work is to be performed, and its tip protrudes from the railway track R.
A dump truck D is kept on standby directly below a hopper 6 provided at the tip of this belt conveyor 5. Then, the worker sequentially digs out the crushed stones from the deteriorated road bed 2' using a heavy machine such as a shovel, places them on the belt conveyor 5, and loads them onto the loading platform of the dump truck D from the hopper 6 at the tip of the belt conveyor 5. After that, new crushed stone is spread between the roadbed 1 and sleepers 3, and the trackbed replacement work is completed.

Problems to be Solved by the Invention In the track bed replacement work using the belt conveyor 5 as described above, as the work progresses, the work area moves away from the belt conveyor 5. Between belt conveyor 5,

In addition, in the track bed replacement work described above, if there is no road or vacant land on the track bed 2' side where the replacement work is being performed, but only on the opposite track bed 2' side, the belt conveyor 5 may be
If an attempt was made to project the belt conveyor in the opposite direction along the line from the arrangement shown in FIGS. 8 to 8, the length of the belt conveyor would sometimes be insufficient.

Furthermore, there are dump trucks D on both sides of railway track R.
There are not always roads or open spaces available to keep the dump truck D waiting, and there are cases where it is not possible to have the dump truck D waiting directly below the hopper 6. In this case, the belt conveyor 5 is It was necessary to move and arrange the belt conveyor 5 to a place where it could be kept on standby, and to arrange the belt conveyors 7, 7, . . . along the trackbed 2 between the belt conveyor 5 and the work place, as described above.

Therefore, in the conventional track bed replacement work, there are many pieces of equipment used for the work, and the belt conveyor 5 is
It takes a lot of time and labor to move the belt conveyors 7, 7, .

The belt conveyor can be easily moved to a work location that moves as the work progresses, and further,
By rotating, swinging, or sliding the belt conveyor relative to the cart, you can avoid obstacles around the work area, or position the hopper above crushed stone transport vehicles such as dump trucks that are waiting away from the work area. can be done. Further, since the belt conveyor can be rotated by the rotation of the turntable and slid in the longitudinal direction, the base end of the belt conveyor can be positioned at an arbitrary location.

Embodiment FIGS. 1 and 2 are drawings showing an embodiment of a road bed replacement work vehicle according to the present invention.

In the drawings, 10 indicates a truck that can move on the rails 4, 4, and 11 indicates a belt conveyor disposed on the truck 10.

A turntable 12 that can swing horizontally is disposed on the cart 10, and a swing frame 14 is mounted on the turntable 12 via a support frame 13 so that it can swing vertically. .

The belt conveyor 11 is attached to the swinging frame 14 so as to be slidable in its own longitudinal direction, so that it can swing horizontally with respect to the cart 10 and swing vertically. It can be slid in any direction.

Furthermore, a hopper 15 is provided at the tip of the belt conveyor 11 for temporarily storing crushed stone transported by the belt conveyor 11 and dropping it onto the loading platform of a dump truck D or the like. 15 is lined with rubber or the like for the purpose of noise prevention and the like.

An example of a road bed replacement procedure using the work vehicle of the present invention will be described below with reference to FIGS. 3 to 5.

First, as shown in Fig. 3, the belt conveyor 1
1 aligned in the front-rear direction of the truck 10, the work vehicle is transported along a track to a predetermined work site by an appropriate towing vehicle.

Next, after stopping the work vehicle at the work site, the fourth
As shown in FIG. 5, the belt conveyor 11
The turntable 12 is adjusted while adjusting the tilt of the swinging frame 14 so that it does not come into contact with the side walls of the elevated structure.
The belt conveyor 11 is moved by the rotation of the cart 10.
In other words, the belt conveyor 11 is rotated in the width direction of the track bed 2', and the belt conveyor 11 is rotated in the width direction of the track bed 2'.
4 and position the hopper 15 at the tip above the road or open space along the railway track R.

Next, the angle of inclination of the belt conveyor 11 is adjusted so as to facilitate the following operation, that is, the operation of placing the crushed stones dug out from the road bed 2' onto the belt conveyor 11, and the opening at the lower end of the hopper 15 is adjusted. A hose 16 made of an appropriate material and having a length that reaches the loading platform of a dump truck D parked on a road or a vacant lot is connected to the hose 16.

In this state, the crushed stones on the deteriorated road bed 2' are sequentially dug out using heavy equipment such as a shovel and placed on the belt conveyor 11.
It is conveyed by the hopper 15 at the tip and thrown into the hopper 15 at the tip.

The crushed stones put into the hopper 15 are sequentially
It is transmitted through the hose 16 and dropped toward the loading platform of the dump truck D. At this time, the hose 16 ensures that the crushed stones are dropped onto the loading platform, and prevents dust from scattering when the crushed stones fall. The dump truck D loaded with crushed stones in this manner transports the crushed stones to a predetermined treatment plant, etc., and an empty dump truck D is made to stand by directly below the hopper 15 in place of this dump truck D. As described above, after removing the crushed stones from the deteriorated trackbed 2' at a predetermined location, new crushed stones are spread between the roadbed 1 and the sleepers 3 to form the trackbed at this location, and from now on, the work will be moved. Therefore, the above-described track bed replacement work is performed while moving the work vehicle.

As the work progresses, the above-mentioned work vehicle is on the railway track R.
When the belt conveyor 11 is moved to the vicinity of a place where overhead wire support poles 17, 17... are arranged on both sides, the belt conveyor 11 is rotated by a predetermined angle by the rotation of the turntable 12, or the swing frame 1
Slide the belt conveyor 11 against 4,
After making sure that the belt conveyor 11 does not come into contact with the utility poles 17, 17..., the belt conveyor 11 is passed through the installation location of the utility poles 17, 17..., and then the hopper 15 at the tip of the belt conveyor 11 is again attached to the road, vacant land, etc. Protrude it towards the end and continue the work as described above.

In addition, if there are no roads or vacant lots along the track on the side of the track bed 2' where replacement work is being performed, and there are roads or vacant lots only along the opposite side, the belt conveyor 11 should be placed in the state shown in Figures 4 and 5. By turning and sliding the belt conveyor 11, the hopper 15 at the tip of the belt conveyor 11 may be projected toward the road or open space.

Furthermore, if the area along the railway track R is a densely populated residential area, etc., and there are no roads or open spaces to keep the dump truck D waiting near the work site, it is difficult to have the dump truck D wait close to the work site. The dump truck D is moved to a place where it can be loaded and is kept waiting there, and the belt conveyor 11 is rotated or slid relative to the cart 10 so that the hopper 15 is positioned above the loading platform of the dump truck D. Do the work.

When the trackbed replacement work for the predetermined section is completed as described above, the hose 16 is removed from the hopper 15, and
After the belt conveyor 11 is slid and rotated to the above-mentioned transport state, it is transported by an appropriate towing vehicle.
Return from work site.

In the above embodiment, the belt conveyor 11 of the work vehicle for roadbed replacement is a single-stage belt conveyor with a constant effective length, but a multi-stage belt conveyor whose effective length can be varied may also be used.

Further, the above working vehicle can be used not only for replacing the track bed 2' on the track side on which the working vehicle is moved, but also for replacing the track bed 2 on the opposite side in the case of a double track as shown in the drawing. That is, by rotating the turntable 12, the belt conveyor 11 is rotated, and by moving the belt conveyor 11 in the longitudinal direction, the hopper 15 of the belt conveyor 11 is rotated.
The proximal end portion not provided with can be positioned above the track bed 2 on the opposite side. Further, the present invention can be used not only for replacing the bed of an elevated railway as in the above embodiment, but also for replacing the bed of a railway track including a general single track.

Effects of the Invention As explained above, the work vehicle for trackbed replacement according to the present invention is provided with a belt conveyor that can turn, swing, and slide with respect to the truck, which can move on a track. Because it was established,
The belt conveyor can be easily moved by the trolley to the work location that is being moved as the trackbed replacement work progresses, and the belt conveyor can be rotated, swung, or moved relative to the trolley. By sliding the hopper, you can avoid obstacles around the work area or position it above a crushed stone transport vehicle such as a dump truck that is waiting away from the work area. First, it is possible to save labor and shorten the work time for track bed replacement work.

In addition, the base end of the belt conveyor without a hopper can be positioned freely, so if there are multiple railway tracks, the belt conveyor can be placed above the track bed on the opposite side where the work vehicle is not moving. By positioning the proximal end of the track bed, it is possible to replace the track bed where the work vehicle is not moving.

Therefore, according to the present invention, it is possible to provide a work vehicle that is highly practical for road bed replacement work.
