Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a rail cleaning vehicle used for removing oil adhering to the inner rail side surface of a rail.

(Background of the Invention) In railroad rails, oil is applied to the inner rail side of the rail, especially at curved portions, in order to reduce wear and noise caused by friction between the flange portion of the wheel and the inner rail side surface of the rail. However, when the multiple tie pads and track inspection vehicles that correct track misalignment run, they scrape up this oil and deposit it on the rail treads, causing the wheels to slip when other trains run. It turns out. Furthermore, if this oil adheres to the multiple tie tamper or the wheels of the track inspection vehicle, the accuracy of track correction and track inspection will decrease.

Therefore, the oil has traditionally been removed prior to such orbit correction and inspection work. This anointing oil is usually hard and solidified, so in the past it had to be scraped off manually by workers in motor cars using a sickle-like tool. For this reason, when performing this work, a work leader, a motor car driver, and a worker who scraped off the oil with a tool were required, which not only required a lot of manpower but also resulted in poor work efficiency.

(Object of the Invention) The present invention was made in view of the above circumstances, and an object of the present invention is to provide a track cleaning vehicle that can efficiently remove oil with less manpower.

(Structure of the Invention) According to the present invention, the purpose is to provide a wire brush that contacts the inner rail side and is rotationally driven by a motor, and a water sprayer that injects high-pressure water toward the rail tread behind the wire brush. This is achieved by a track cleaning vehicle characterized by comprising a nozzle and a high-pressure water spray unit that pumps high-pressure water to the water spray nozzle.

(Embodiment) Fig. 1 is a side view of an embodiment of the present invention, Fig. 2 is an enlarged side view of the main parts thereof, Fig. 3 is a rear view,
FIG. 4 is a sectional view taken along the - line in FIG. 2.

In FIG. 1, the reference numeral 10 is a trolley, and this trolley
A water tank 12 and a high-pressure water sprinkler unit 14 are mounted on the . This truck 10 is pulled to the left in the figure on a rail 16.

A wire brush 20 and a water nozzle 22 are attached to the rear of the truck 10 by a brush pressing mechanism 18. This brush pressing mechanism 18 is constructed as follows. That is, as shown in FIGS. 2 to 4, a pin 24 is provided horizontally protruding rearward at the rear of the truck 10, and a vertical plate 26 is swingably attached to the pin 24. This vertical plate 26 can be rotated in the width direction of the truck about a pin 24 by a cylinder 28 (FIG. 3) held on the truck 10, and can be fixed at an appropriate rotational position. Vertical board 2
A horizontal plate 32 is attached to the lower edge of 6 by a hinge 30 so as to be swingable in the vertical direction. This horizontal plate 32 is connected to a cylinder 34 held on the trolley 10.
It can be rotated up and down about the hinge 30 and fixed at an appropriate position. The lower end of the piston rod of this cylinder 34 is connected to the horizontal plate 32 via a spherical bearing. This horizontal plate 32
A motor holding plate 36 is attached to the lower surface of the carriage so as to be movable in the width direction of the carriage. That is, four rolling bearings 38 for linear motion (two are shown in FIG. 3) are attached to the lower surface of the horizontal plate 32, and two support shafts are attached to each of the two bearings 38 so as to be slidable in the width direction of the truck. 40, 40 (see FIG. 2) are held, and both ends of each of these support shafts 40, 40 are fixed to the upper surface of the motor holding plate 36. As shown in FIG. 4, a cylinder 42 is held on the lower surface near the center of the horizontal plate 32 in the width direction of the truck, and a piston rod 44 of this cylinder 42 is connected to the motor holding plate 32. Therefore, this cylinder 42 allows the motor holding plate 36 to move in the width direction of the truck.

A motor 46 is fixed to the lower surface of the motor holding plate 36, and the wire brush 20 is fixed to a rotating shaft 48 of the motor 46. Further, a front water spray nozzle 22 is fixed to one side edge of the motor holding plate 36, that is, the side edge on the wire brush 20 side. The water nozzle 22 is directed from above the wire brush 20 toward the tread surface 16A of the rail 16 behind the wire brush 20, and spreads in a fan shape in the width direction of the truck and sprays water in a narrow range in the vertical direction. It is preferable that the direction in which this water is jetted forms an angle of about 30 to 40 degrees with the rail 16, as shown in FIG.

Therefore, by controlling the cylinders 28, 34, and 42, the wire brush 20 can be brought into contact with the inner side surface of the rail 16 at an appropriate angle and with an appropriate pressing force.

As shown in FIG. 3, if the high-pressure water is spread in the width direction above the polishing surface of the wire brush 20, the oil splashed by the wire brush 20 as it rotates will be absorbed into this high-pressure water. It can then be captured and transported to the orbital floor along with water. Therefore, the oil splashed by the wire brush 20 is on the road surface 16A.
It is possible to reliably prevent the product from adhering to the surface.

Further, the oil removed by the wire brush 20 and the oil carried by high-pressure water may be collected by a separately provided recovery machine (not shown).

(Effects of the Invention) As described above, the present invention brings a rotating wire brush into contact with the inner side surface of the rail, and injects high-pressure water from a water spray nozzle onto the rail tread behind the wire brush. . Therefore, the coated oil can be scraped off with a wire brush, and the scraped coated oil can be scattered with high-pressure water. Therefore, the oil can be removed efficiently and labor can be saved.
