Abstract

PURPOSE:To perform ballast renewal with good efficiency and to easily perform a work in a small place. CONSTITUTION:A vibrating container 4 having slits 13 where only the fine- grained small piece ballast 15 is passed is vibrated to excavate ballast 5, so that only the small piece ballast 15 is stored in the vibrating container 4. The standard ballast 16 is left behind as it is, and only the small piece ballast 15 is selectively discharged, so that the need of a sorting work can be eliminated so as to perform ballast renewal work with good efficiency and the work can be easily performed in a small place.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roadbed replacing machine for removing crushed and atomized ballast of a railroad roadbed.

[0002]

2. Description of the Related Art A conventional roadbed replacement machine is shown in FIGS.
Shown in. FIG. 4 is a side view before the roadbed replacement work, FIG. 5 is a plan view before and after inserting the undercutter, and FIG. 6 shows a front view after the insertion.

The details of this machine will be described with reference to the drawings. On the frame 52 which is provided in front of the truck 51, the tray 54, the rotary shaft 53 and the belt conveyor 57 are provided.
Is attached. A curved undercutter 55 is attached to the rotary shaft 53, and a chain cutter 56 composed of a plurality of blades is attached around the curved undercutter 55. Further, a motor 58 for driving the chain cutter 56 is provided above the under cutter 55.

The following is a description of the roadbed replacement work procedure by this machine. First, by rotating the motor 58, the chain cutter 56 rotates along the outer circumference of the under cutter 55. In this state, the undercutter 55 set in parallel with the rail 61 is inserted into the ballast 59 under the sleeper 60 by rotating it 1/4 of the rotation axis 53, and is orthogonal to the rail 61.

During the replacement work, the carriage 51 is moved forward, and the chain cutter 56 rotating at this time causes the sleeper 60 to move.
The lower ballast 59 is continuously excavated, and the excavated ballast 59 is scraped up onto the frame 52. The scraped ballast 59 falls into the tray 54 and is conveyed by the belt conveyor 57 into the carriage 51 at the rear. After that, classification of the ballast scraped by the subsequent equipment, supply of new ballast, compaction, etc. are performed, and the replacement work is completed.

[0006]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
Since the ballast 59 is excavated and scraped up by the chain cutter 56, there is a possibility that the small-grained ballast may be missed. Moreover, since all the ballasts 59 are scraped up, it is necessary to classify the ballasts within the specifications that have not been made into fine particles, resulting in poor efficiency.
Furthermore, the chain cutter 56 projects to the side of the rail 61 and becomes wider, making it difficult to work in a narrow place such as in a tunnel.

[0007]

Means for Solving the Problems The structure of the present invention for solving the above-mentioned problems is to excavate ballast by vibration and to make it finer in a roadbed replacing machine for removing ballast of a crushed and atomized railway roadbed. The vibrating container is provided with a slit through which the small piece ballast passes and in which only the small piece ballast passing through the slit is accommodated, and a suction device for sucking and discharging the small piece ballast accommodated in the vibrating vessel.

[0008]

By excavating with the vibrating container, only the small piece ballast passes through the slit and is accommodated in the vibrating container, and the ballast within the standard remains without being accommodated in the vibrating container, and only the small piece ballast is the suction device. Is sucked and discharged by.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a side view showing the entire roadbed replacement machine according to an embodiment of the present invention, and FIG. 2 is a plan view of FIG.
FIG. 3 shows a sectional state of the vibration container.

As shown in FIGS. 1 and 2, a sleeper 6 is provided on the ballast 5, and a rail 12 is laid on the sleeper 6. The trolley 1 is installed on the rail 12 via the wheels 10, and the trolley 1 can travel along the rail 12 by the wheels 10. A suction pump 7, a discharge part 8 and a loading container 9 are installed on the dolly 11, and the suction pump 7 is connected to the discharge part 8 by a transport pipe 20. Further, vertical oscillating shakers 2 are provided symmetrically on the side of the carriage 1, and the vertical directional shakers 2 are connected to each other by a lateral directional shaker 17. A plurality of spokes 3 extending downward in the vertical direction are attached to the vertical exciter 2, and the spokes 3 are located on the sides of the sleepers 6. A vibration container 4 is fixed below the spokes 3, and the vertical vibration device 2 and the lateral vibration device 17 apply vibration to the vibration container 4. The ballast 5 is excavated by vibrating the vibration container 4.

As shown in FIG. 3, the vibrating container 4 is hollow and has an inclined surface 18 at the front. A suction port 14 is provided on a side portion of the vibration container 4, and the suction port 14 serves as the discharge pipe 11.
(See FIG. 2) through the suction pump 7 (see FIGS. 1 and 2)
Connected to. Inclined surface 18 and upper surface 1 of vibration container 4
A large number of slits 13 are formed in the slit 9. The slits 13 are set to have a size that allows only the small-sized ballasts 15 of the ballast 5 to pass through, and the non-granulated in-standard ballast 16 cannot pass through. ing. That is, when the ballast 5 is excavated by the vibration container 4, only the small piece ballast 15 passes through the slit 13 and is accommodated in the vibration container 4.

The operation of the above-configured roadbed replacement machine will be described.

The trolley 1 travels along the rail 12 at a low speed. By the operation of the vertical directional exciter 2 and the lateral directional exciter 17, the vibration container 4 vibrates vertically and horizontally via the spokes 3. By the traveling of the carriage 1 and the vibration of the vibration container 4, the vibration container 4 excavates the ballast 5, and at the same time, the ballast 5 riding on the inclined surface 18 and the upper surface 19 is sieved by the slit 13.

Of the ballasts 5, only the small-grained ballasts 15 that have been granulated pass through the slits 13 and are accommodated in the vibrating container 4, and the non-granulated standard ballasts 16 are accommodated in the vibrating container 4. Instead, it is left behind in the device.

Small piece ballast 15 housed in the vibration container 4
Is discharged from the suction port 14 through the discharge pipe 11 by the suction force of the suction pump 7. Suctioned small piece ballast 15
Is loaded into the loading container 9 from the discharge part 8 through the transport pipe 20.

By performing this work continuously, only the small piece ballast 15 is discharged, and the in-standard ballast 16 can be left. As a result, the roadbed replacement work is completed only by newly supplying the required amount of the in-standard ballast 16, and the classification work is not required.

The above-mentioned ballast replacement machine is a small piece ballast 15
Can be discharged, and the roadbed replacement work can be performed without performing classification work. Further, since the small piece ballast 15 is discharged by the suction force of the suction pump 7,
Only the discharge pipe 11 projects to the side portion, and the width does not widen.

[0018]

EFFECTS OF THE INVENTION The ballast exchanging machine of the present invention vibrates a vibrating container having a slit through which only small-sized ballasts pass, excavates the ballast, and stores only the small-ballasts in the vibrating container. The non-fine-grained ballast within the standard is left as it is, and the small piece ballast in the vibration container is sucked and discharged by the suction device, so it is possible to selectively discharge only the small piece ballast, and to the side of the device. Only the discharge pipe connected to the suction device can be extended. As a result,
No classification equipment is required, and by supplying ballast within the specifications, it is possible to perform roadbed replacement efficiently, and it becomes easy to work in narrow places such as tunnels.
