Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of repairing a ballast ballast for a high-speed railway such as a Shinkansen and an improvement of a repair device used for the method.

[0002]

2. Description of the Related Art In recent years, in high-speed railways such as Shinkansen, the train traveling speed has been increased and high-speed operation exceeding 300 km / hr has been performed. However, with the speeding up of trains, various problems are starting to occur in each department of vehicles and roadbeds.In particular, in the ballast roadbed department, the damage of vehicles due to the scattering of the ballas and the people near the track The occurrence of harm to private houses has become a serious problem.

That is, a track bed for a high-speed railway is usually repaired by using a multiple tie tamper. However, when the ballast ballast is hardened with a multiple tie tamper, it is inevitable that the ballast debris is generated, and the generated ballast debris mainly floats above the ballast ballast and is large on the ballast surface layer. There will be many.

On the other hand, the traveling speed of the train is 300 km / hr.
Or, at high speeds beyond this, small-diameter balls (having a particle size of about 20 to 30 mmφ or less) existing on the outer surface of the roadbed balls laid between the sleepers or on both sides of the sleepers, or on the upper surface of the sleepers. The balas is rolled up by wind pressure, collides with the vehicle body, and is scattered outward.

On the other hand, in order to prevent scattering of the ballast ballast,
The first measure that was adopted was to lower the laying height of the ballast that had been laid to almost the same level as the sleeper upper surface by about 50 mm from the sleeper upper surface, and drop the ballast on the sleeper upper surface downward. This is a method to prevent the scattering of loose particles. However, the method of lowering the laying height of the ballast has a drawback that the so-called roadbed resistance is reduced and the track is liable to be deviated, and the scattering of the ballast cannot be completely prevented.

Therefore, the method adopted next is a method of using a powerful vacuum suction machine to suction the small diameter ballast existing on the outer surface layer of the ballast bed and remove it. But,
This suction method has a very poor working efficiency, and in reality, it is impossible to completely remove the small diameter ballast, and there is a drawback that the risk of scattering the ballast still remains. Further, since the outer surface of the ballast bed is not smooth, even if a vacuum leak preventer such as a rubber plate is used, the vacuum leak from the suction port will be considerably large, and a large-capacity vacuum suction device is inevitably required. There are difficulties.

[0007]

DISCLOSURE OF THE INVENTION The present invention provides a method for lowering the laying level of a ballast ballast as described above in a roadbed repair for preventing the ballast scatter of a ballast ballast for a high-speed railway. In addition to reducing the resistance and causing rail deviation, it is not possible to completely prevent scattering of the balls.The method using a vacuum suction machine has extremely poor work efficiency, and fine particles are completely removed. It is not possible to do this, and the problem is that a large-capacity vacuum suction device is required. It also provides a method for repairing ballast ballasts for high-speed railways, which can prevent the scattering of balls during high-speed running of a train with high efficiency and completely by sunk below, and a repair device used for this. It is.

[0011]

The vibration of the high-frequency vibration generator is transmitted to the ballast layer through the vibrating body penetrating into the ballast layer. The finer the grain size of the ballast layer, which is subjected to high-frequency vibration, is more strongly influenced by the vibration force, and is sequentially transferred downward through the gaps between the large grain size balls, which is almost equivalent to the height of the vibrator. It sinks into the depth of the ballas layer.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a first repair device used for carrying out the method invention, and FIG. 2 is an explanatory view of a repair state of a ballast bed by the first repair device. In FIGS. 1 and 2, 1 is a high-frequency vibration generator (vibration motor), 2 is a flat plate-shaped stand, 3 is a vibrating body, 4 is a string body (or elastic body), 5 is a gripping body, and 6 is a sleeper. , 7 is a roadbed ballast, 7a is a large particle size ballast, 7b is a small particle size ballast, and 8 is a vibrating body composed of a vibration generator 1, a flat plate-shaped mount 2 and a vibrator 3.

A vibration motor is used for the high-frequency vibration generator 1, and in the present embodiment, an AC motor having a frequency conversion type speed controller having a capacity of 1.2 kw and a rotation speed of 6000 to 7200 RPM is used. . Weights of appropriate weights are eccentrically fixed to both ends of the rotor shaft of the vibration motor 1, and the rotor shaft rotates at a high speed so that the motor body itself centrifuges the eccentric weight. It vibrates by force. Further, the vibration motor 1 is supported and fixed on the upper surface side of the flat plate-shaped stand 2, and the vibration motor 1
Is rotated and circularly oscillated, so that the flat plate-shaped base 2 and the vibrating body vibrate together with the motor 1.

The vibrating body 3 is fixed to the lower surface side of the flat plate-shaped mount 2 in a posture of projecting downward, and in this embodiment, two plate-like bodies (height: about 150 mm, length: about 200 mm).
Are arranged side by side at a pitch of about 75 mm. The vibrating body 3 may be rod-shaped or pin-shaped, and a plurality of rod-shaped bodies may be provided so as to project downward from the lower surface of the flat plate-shaped mount 2. In this case, the rod-shaped or pin-shaped vibrator 3 has 30 to 7
It is desirable to project in parallel at intervals of 5 mm. Vibrating body
If the interval of 3 exceeds 75 mm, the vibration in the ballast layer B
This is because it is difficult to achieve uniform transmission, and the spacing is 3
If it is smaller than 0 mm, it will be dispersed by the large grain size ballast 7a.
This is because the penetration into the layer B is easily prevented. Also, rod-shaped
Alternatively, the pin-shaped vibrating body 3 is a mutual sleeper on the lower surface of the flat plate-shaped mount 2.
Projected in parallel in the part of the width dimension shorter than the dimension between
The vibrating body 3 is blocked by the sleepers.
Smoothly into the ballast layer B between the sleepers without
You can go in.

A fiber or rubber cord (including a belt) is used for the cord 4, and the vibration transmitted from the flat plate-shaped base 2 to the gripper 5 is absorbed by this. Further, although the cord body 4 is used in this embodiment as described above, an elastic body such as a coil spring may be used instead of the cord body 4.

When repairing the ballast bed 7, first, the ballast etc. on the upper surface of the sleeper 6 is blown off by compressed air to clean the upper surface of the sleeper. Next, the repair device of the present case is arranged between the sleepers in a state as shown in FIG. 2, and the high-frequency vibration generator 1 is activated to operate the vibrator 2
High frequency vibration of about 50 to 250 Hz is applied to.

That is, an operator holds the vibrating body 8 composed of the vibrating motor 1, the vibrating body 2 and the flat plate-shaped mount 3 with the grip body 5, and places the vibrating body 8 on an appropriate place on the ballast bed.
After that, the vibration motor 1 is operated. When the vibration motor 1 is operated, the vibrating body 3 vibrates due to the weight of the vibrating body 8, and the vibrating body 3 vibrates and sequentially penetrates into the vibrating layer B.
Vibration is transmitted inside.

When the vibration is transmitted into the ballast layer B, as shown in FIG.
As shown in, the finer grain size ballast 7b receives the kinetic force due to the vibration and sinks downward through the gap of the large grain size ballast 7a. According to the result of the experiment, the closer the vibrating body 3 is, the faster the fine grain size ballast 7b sinks, and the sinking depth is approximately the maximum depth at the height dimension (150 mm in this embodiment) of the vibrating body 3. .

When the fine grain size ballast 7b in the vicinity of the vibrating body 8 is completely sunk, the vibrating body 8 is pulled upward and moved to an adjacent position, and subsequently the vibrating body 3 is inserted into the ballast layer B, Perform similar processing.

According to the result of the experiment, the vibrating body 1 of this embodiment is
Using the base, the distance between the sleepers 6 and the sleepers 6 is about 500 mm,
When repairing a ballast bed with a sleeper length of about 2300 mm, the ballast bed treatment between two sleepers could be completed in about 5-6 minutes. In addition, the fine-grained ballast 7 having an outer diameter of 20 to 30 mmφ existing on the outer surface layer of the ballast bed 7 is used.
Almost all of b is sunk below the first layer of the large particle size ballast 7a.

In the embodiment shown in FIG. 1, the high frequency vibration generator 1 is a high frequency vibration motor (1.2 kw,
Although 6000 RPM and a vibration frequency of 200 Hz) are used, a vibration device that uses an electromagnetic solenoid instead of the vibration motor may be used. Further, the vibration frequency of the vibration generator 1 is more convenient as the frequency is higher and the amplitude is higher, but it is about 50 to 250 Hz when judged from the cost and handleability of the device.
Is optimal , and when the vibration frequency is 50 Hz (the rotation speed of the vibration motor is 1500 RPM or less), the effect of sinking the fine particle size variation is significantly reduced.

Further, in the present embodiment, two workers work with the grippers 5 from both sides, but it is also possible for one worker to operate the device. In addition, in this embodiment, the plate-shaped vibrating body 3 is arranged in parallel with the rotation axis of the vibration motor, but it is also possible to arrange the plate-shaped vibrating body 3 in a direction orthogonal to the rotation axis. .

FIG. 4 shows another embodiment of the repairing device according to the present invention, which is a work cart 9 traveling on a rail.
The vibrating body 8 is attached on the top. In Figure 4, the working carriage 9, 10 is a cylinder device which supports fixed to the work carriage, 11 caused isolator supporting lifting member fixed to the distal end of the piston rod 10a, 4 are cords or elastic member, 8 Is a vibrating body.

The work carriage 9 may be a self-propelled type or a towed type, but the self-propelled type is preferable. The work carriage 9 is provided with a support base 9a, to which the cylinder device 10 is attached and fixed.

The cylinder device 10 is for suspending and supporting a plurality of oscillators 8 via an oscillator support member 11 so that the oscillators 8 can be moved up and down, and the tip of the piston rod 10a is horizontally long. The vibrator support member 11 is fixed.

The vibrating member support member 11 is a horizontally elongated steel member arranged in the direction orthogonal to the rails, and the length dimension thereof is selected to be substantially equal to the lateral width dimension of the track bed. As shown in FIG. 5, 4 to 6 vibrators 8 are suspended from and supported on the vibrator support member 11 via a cord body or a belt body 4, and the vibration is generated by the operation of the cylinder device 10. The body 8 is lowered onto the ballast ballast.

In the embodiment of FIGS. 4 and 5, 1
The base cylinder device 10 simultaneously raises and lowers all the vibrating bodies 8 through the vibrating body support member 11. However, a plurality of cylinder devices 1 corresponding to the number of the vibrating bodies 8 are used.
1 may be provided and the vibrating body 8 may be moved up and down individually or in groups.

The repair of the ballast bed by the repair device of FIG. 4 is basically the same as that of the repair device of FIG. At the time of repair, first, the carriage 9 is carried to the work site, and first, the compressed air from the loaded compressor device (not shown) blows off the ballast on the upper surface of the sleeper. Next, the vibrating body 8 is positioned above the sleepers and the vibration motor 1 is driven. At the same time, the cylinder device 10 is operated to lower the vibrator 8 through the vibrator support member 11 onto the ballast ballast.

The vibrating body 8 descended onto the ballast ball slab is oscillated by its own weight and high frequency vibration into the ballast layer B in sequence so that the vibratory body 3 on the lower surface of the cradle is subjected to the high frequency vibration. As a result, as in the case of FIG. 2, the small particle size ballasts 7b settle down downward through the gaps of the large particle size ballasts 7a, and the small particle size ballasts 7 are formed on the outer surface layer portion of the ballast layer B.
b almost disappears.

[0030]

According to the present invention, the vibration pair 3 applies high frequency vibration to the ballast layer B having a depth of about 50 to 200 mm from the outer surface. As a result, the fine grain size ballast 7b existing in the outer surface layer portion of the ballast layer B receives a large vibration force, and vibrates more violently than the large grain size ballast 7b. As a result, the small particle size ballasts 7b smoothly settle down through the gaps between the large particle size ballasts 7a, and the fine particle size ballasts 7b in the vicinity of the vibrating body 3 are settled in a very short time. Below the outermost surface layer (for example, 30 to 4
It is possible to settle to the surface of 0 mm below the large particle size ball lower than the first layer), and it is possible to greatly improve the work efficiency of repair work for preventing scattering of the ball.

Further, in the present invention, since the small-diameter ballast is settled down in the ballast layer B, the so-called ballast track resistance of the ballast track is further increased, and the maintenance of rails and sleepers is improved. Is also extremely advantageous. INDUSTRIAL APPLICABILITY As described above, the present invention can easily and reliably prevent various inconveniences caused by scattering of roadbed ballasts in a high-speed railroad with high efficiency, and has excellent high practical utility.
