Description

[Detailed description of the invention] This invention eliminates the ballast scattered on the top surface of sleepers and rails after tamping and other straightening work of the ballast track bed of railway tracks, and flattens the ballast on the top surface of the track bed. The present invention relates to a dust-proof water spraying device for a ballast sweeper that cleans a ballast track bed.

As shown in FIG. 1, a conventional ballast sweeper 1 has a front wheel 2 and a rear wheel 3, a trolley 5 that can run on rails 4, and a rotating brush rotatably attached to the trolley 5. It consists of a device 6 and a hydraulic cylinder 7 for storing the settings of this rotating brush device 6. The rotating brush device 6 includes a prime mover (engine, electric motor, hydraulic motor, etc.) 8, a rotating brush 10 rotated by the prime mover 8 via a power transmission mechanism 9, and a rotating brush 10 rotatably supported inside. , the rear end is connected to the trolley 5 via the pin 11.
The brush cover 12 is rotatably attached to the brush cover 12. The hydraulic cylinder 7 is rotatably attached to the truck 5, and the tip of its piston rod 13 is connected to the brush cover 12 of the rotating brush device 6 via a pin 14. By retracting the piston rod 13, the rotating brush device 6 is rotated upward about the pin 11 to store and hold the rotating brush device 6 within the limits of the vehicle when the ballast sweeper 1 is transported to a work site or base, and
By pushing out the piston rod 13, the rotary brush device 6 is rotated downward about the pin 11 and lowered onto the upper surface of the ballast track bed 15 of the track, setting and holding the rotary brush device 6 in the working position. Therefore, in order to clean the ballast track bed 15 with the ballast sweeper 1, the hydraulic cylinder 7 first lowers the rotary brush device 6 to the upper surface of the ballast track bed 15 at the working position. Next, the prime mover 8 is started, the rotating brush 10 is rotated in the direction of arrow 16 via the power transmission mechanism 9, and while the ballast sweeper 1 is running on the rail 4 in the direction of arrow 17, the ballast is removed by multiple damper or the like. After tamping the trackbed 15 or adjusting the ballast trackbed 15 by a ballast regulator, the sleepers 18
The ballast scattered on the top surface of the ballast track bed 15 is also splashed off and cleaned by the rotating brush 10, and excess ballast on the top surface of the ballast track bed 15 is also splashed off to clean the top surface of the ballast track bed 15 so that the top surface is flat. . However, in this case, the upper surface of the track, that is, the sleepers 18, the rails 4 and the ballast track bed 1
The dust accumulated on the upper surface of the brush cover 5 and the dust attached to the ballast are agitated by the air flow generated by the rotating brush 10, and the brush cover 12
The dust that flies up inside the brush cover 12 and the upper surface of the track, that is, the sleeper 18,
In order to prevent dust from flying up from the top surface of the track, the ballast should be sweeper 1
The ballast sweeper 1 was cleaning the track while spraying water on the top surface of the uncleaned track in front of the train. However, spraying water on the top surface of the uncleaned track in front of the ballast sweeper 1 to prevent dust from flying up during cleaning requires a huge amount of water, and especially in summer, the temperature of the top surface of the track increases. As the amount of water increases significantly and the sprinkled water evaporates rapidly, it is almost impossible to prevent dust from flying up by sprinkling water.
Another drawback is that half-hearted watering cannot prevent dust from flying up.

The present invention was developed to solve the above-mentioned drawbacks, and it sprays water in the form of a mist inside the brush cover of a rotating brush device, and as the rotating brush rotates, the inside of the brush cover is constantly covered with water droplets in the form of mist. The dust is filled uniformly, and the dust that has flown up is attached to the atomized water droplets, which are allowed to fall onto the top surface of the track.The top surface of the track is moistened to prevent dust from flying up, and the bottom end of the brush cover is shielded. To provide a dustproof watering device for a ballast sweeper which has an effective dustproof effect with a small amount of water sprayed by attaching a curtain and preventing mist water droplets from leaking to the outside.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 2 is a cross-sectional side view of a main part of a ballast sweeper to which a dust-proof water sprinkler according to an embodiment of the present invention is attached.

In FIG. 1 and FIG. 2, the same numbers indicate the same members.

In FIG. 2, the dust-proof watering device 20 includes a water tank 21 attached to the trolley 5 of the ballast sweeper 1, and is arranged above the water tank 21, and is driven by a dedicated drive device (not shown). Pump 22 and brush cover 12 of rotating brush device 6
A nozzle 2 is attached to the brush cover 12 and sprays water discharged from the pump 22 into the inside of the brush cover 12 in the form of a mist.
3, a water pipe 24 that connects the pump 22 and the nozzle 23, and a water pipe 24 that is provided at the lower end of the brush cover 12 to prevent mist water droplets sprayed inside the brush cover 12 from leaking outside. It is composed of a shielding curtain 25 that blocks the inside and the outside.

Next, the operation of the dust-proof water sprinkler device for a ballast sweeper having the above-described configuration will be explained.

When the pump 22 is started, the water in the water tank 21 is sucked up by the pump 22 and sent to the water pipe 24.
from the nozzle 23,
A mist is sprayed into the brush cover 12. Therefore, during cleaning work, the mist-like water droplets sprayed into the brush cover 12 from the nozzle 23 are agitated by the rotating brush 10, but since they are blocked from the outside by the shielding screen 25, the brush cover 12 The dust fills the space uniformly and attaches to the dust flying up from the top of the orbit, increasing the mass of the dust. This increased mass of dust falls onto the upper surface of the orbit and moistens the upper surface of the orbit, thereby suppressing the dust from rising up from the upper surface of the orbit.

As described above, the dust-proof water spraying device for a ballast sweeper of the present invention uses a nozzle to spray water in the form of a mist into the inside of the brush cover, which is isolated from the outside, and uses the agitation action caused by the rotation of the rotating brush to form water droplets in the form of a mist. Evenly fills the inside of the brush cover and attaches to the dust flying up from the top surface of the track, increasing the mass of the dust, causing it to fall to the top surface of the track, moistening the top surface of the track, and removing dust from the top surface of the track. Since dust is suppressed from flying up, it is possible to prevent dust from flying up from the upper surface of the track. In addition, since the inside of the brush cover is isolated from the outside by a shielding screen, the mist water droplets sprayed inside the brush cover by the nozzle will not leak to the outside, so the dustproof effect is effective even with a small amount of water sprayed. can be raised.
