Description

  The present invention relates to a coating apparatus for coating a rail side surface of a railway.

  As a countermeasure against thermal expansion of rails in railways, Patent Document 1 proposes that heat-shielding (light-shielding) coating is applied to the side surfaces of the laid rails to suppress the temperature rise of the rails in summer. The device of Patent Document 1 is a device that sprays and coats a thermal barrier paint on a rail side surface through a nozzle from a coating device on the carriage while moving the carriage on the track at a constant speed.

JP 09-173923 A

  As shown in FIG. 3 of Patent Document 1, the thermal barrier coating applied to the rail is limited to the side surface, and the head of the rail on which the wheel is placed must be left unpainted. Therefore, in the case of the apparatus of Patent Document 1, as shown in FIG. 2 of Patent Document 1, the coating range is limited by dropping the nozzle from the side of the carriage to the vicinity of the rail side surface and spraying the paint. However, there are fasteners such as panda rolls and seam plates on the side of the laid rail, and these are obstacles to the movement of the nozzle. It is actually difficult to arrange the nozzles.

  In view of such a background, there is a need for a rail coating apparatus having a structure capable of performing thermal barrier coating on the side of the rail while reliably leaving the rail head uncoated.

The rail coating apparatus proposed for the above-mentioned problems is attached to each rail of the track by attaching to the first cart traveling on the track and the traveling direction end of the first cart. And a spraying mechanism for spraying paint on the side surface.
The spray mechanism includes an arm that is hinged to the first carriage so as to be swingable in the horizontal direction, and a wheel that is hinged to the tip of the arm so as to be swingable in the horizontal direction and that runs on the rail. And a masking plate that hangs down from the frame and extends to the side of the rail head, and is attached to the frame so that the distance from the rail side surface can be adjusted, and the extending position of the masking plate And a nozzle for spraying paint on the rail side surface.

The spray mechanism of the rail coating apparatus according to the above proposal is such that the masking plate hangs down from the frame that moves along the rail as the wheels run on the rail, and the masking plate is on the side of the rail head when painting. Extending towards. Since the nozzle sprays paint at a position where the masking plate extends, the rail head is always masked by the masking plate against the paint to be sprayed.
Since the rail head is masked by the masking plate, even if the nozzle is placed away from the rail side to avoid obstacles on the side of the rail, and the rail head enters the area where the spray paint spreads The masked rail head is left unpainted.

  FIG. 1 and FIG. 2 show an embodiment of a rail coating apparatus having a three-car train (tro). In the illustrated example, the first carriage 1 is the last, the second carriage 2 is the middle, and the third carriage 3 is the power vehicle and is the leading vehicle (conversely, the first carriage 1 is the leading, The third carriage 3 can also be the last). These trolleys 1 to 3 have the same structure, and are connected at a predetermined interval by the connector 4, and advance and retreat on the track by driving the third trolley 3. The wheels 5 of the carriages 1 to 3 are coated with an insulating material so that no current flows through the laid rail R. The distance between the left and right wheels 5 can be adjusted by inserting / removing the collar member at the end of the axle in accordance with the gauge such as narrow gauge, standard gauge, and wide gauge.

  As for the 1st trolley | bogie 1, the spraying mechanism 10 which sprays a heat-shielding coating material on the side surface of the rail R is attached to the advancing direction edge part. On the first carriage 1, a manual operation valve 11 that controls the supply of the thermal barrier paint to the spray mechanism 10 and a pump 12 that sends out the thermal barrier paint are placed. The pump 12 is of a size that can be carried by hand.

The second carriage 2 carries a large number of paint containers 20 such as a funnel that stores thermal barrier paint supplied to the pump 12.
The third carriage 3 carries a generator 30 and supplies power to the power source motor 32 through a control box 31 including an inverter, whereby the third carriage 3 serves as a power car for other carriages 1 and 2. Tow. Although not shown, the power source motor 32 drives the wheels 5 in a chain manner. A control panel 31a corded to the control box 31 is attached to an inverted U-shaped handrail 33 fixed on the carriage 3 by screwing or the like, and an operator on the third carriage 3 can control the control board 31a. By operating 31a, forward, backward, and speed control is executed. The generator 30 may be a storage battery. The generator 30 is of a size that can be carried by at least two people.

  The first to third carts 1 to 3 are made of aluminum and light and can be carried by several people. Therefore, when the train is approaching during the painting work, the connecting tool 4 is removed, and the pump 12, the paint container 20, the generator 30, and the carriages 1 to 3 are carried out of the track and retracted by the operator's hands. Can do.

  At the time of painting by this rail coating apparatus, an operator is on the third carriage 3, a paint supply worker is on the second carriage 2, and a spraying worker is on the first carriage 1.

The spray mechanism 10 attached to the 1st trolley | bogie 1 is demonstrated with reference to FIGS. 1-3.
In the case of this example, the blowing mechanism 10 is provided on each of the left and right sides corresponding to the rail R at the rear end portion in the traveling direction of the first carriage 1. For this purpose, a pedestal square pipe 10a laid sideways is fixed to the rear end corner of the first carriage 1 by welding or the like, and spaced apart on the pedestal square pipe 10a, the two support square pipes 10b are It is erected by welding. A bearing bracket 10c protrudes rearward and is fixed by welding or the like to the side surface of the pillar square pipe 10b, and a vertical rotation shaft 10d is pivotally supported by the protruding portion of the bearing bracket 10c. An arm support bracket 10e is formed on the vertical rotation shaft 10d. Two hinge shafts 10f are spaced apart and supported in parallel between the flanges of the arm support bracket 10e, and the two arms 10g are hingedly connected to the hinge shaft 10f so as to be swingable in the horizontal direction.

  The arm 10g extends obliquely downward, and a frame 10h is hinged to the tip of the arm 10g so as to be able to swing in the horizontal direction. The two arms 10g connected to the frame 10h are parallel to each other to form a parallel link. Specifically, a U-shaped arm connection bracket 10i is fixed to the side surface of the front end portion of the frame 10h by welding or the like, and a hinge shaft 10j is pivotally supported on the arm connection bracket 10i, and the arm 10g is supported by the hinge shaft 10j. Are hinged. The arm 10g can be a single-sided cantilever type on one side, but the parallel link system using the two arms 10g may be stable.

  The frame 10h has a downward U-shape, and supports a wheel 10k that travels on the rail R inside. Therefore, the frame 10h held so as to be swingable in the horizontal direction by the arm 10g is guided by the wheel 10k and traces the rail R. For this purpose, the wheel 10k is formed with flanges on both the left and right sides.

  The upper end portion of the masking plate 10l is fixed to the lower end portions of the left and right side surfaces of the frame 10h by bolting or the like, and the masking plate 101 is suspended further downward from the frame 10h. The frame 10h has an extended portion extending rearward at the lower end portion, and the masking plate 101 has a length including the extended portion and extends to the side of the rail R head. Such a masking plate 101 may be formed of a material softer than the rail R, such as rubber, synthetic resin, or wood. In this example, the masking plate 101 is provided on both the left and right sides of the frame 10h. However, when the rail side surface to be subjected to the thermal barrier coating is only one side, that is, the thermal barrier coating is applied only to the side exposed to sunlight. In such a case, the masking plate 101 may be provided only on the corresponding one side together with the nozzle 10q.

  A wide and flat mounting surface is formed on the upper surface of the frame 10h, and a nozzle support bracket 10m is fixed to the mounting surface. The nozzle support bracket 10m holds the horizontal rod 10n. Accordingly, the position adjustment clamp 10o is attached to the horizontal rod 10n extending in the left-right direction, and the vertical rod 10p is clamped to the position adjustment clamp 10o. A nozzle 10q is connected to the tip of the vertical rod 10p. The vertical rod 10p also plays the role of a thermal barrier paint supply pipe, and the nozzle 10q to which the thermal barrier paint is sent through the vertical rod 10p applies the thermal barrier paint toward the rail R side surface at the extended position of the masking plate 10l. Spray.

  The position adjustment clamp 10o can be slid along the horizontal rod 10n to adjust the position, and the clamp position of the vertical rod 10p can be adjusted. Therefore, the nozzle 10q can adjust the distance (horizontal interval) and the height from the side surface of the rail R by the position adjustment clamp 10o.

  A paint hose 10 r is connected to each of the vertical rods 10 p, and the paint hose 10 r is connected to the pump 12 via the manual operation valve 11. The pump 12 sucks up the thermal barrier paint in the paint container 20 by the suction hose 12a and discharges it to the paint hose 10r. The pump 12 is supplied with power from the generator 30.

  Since the arm support bracket 10e to which the arm 10g of the spraying mechanism 10 is connected is attached by the vertical rotation shaft 10d as described above, the arm 10g can be rotated in the vertical direction and connected to the first carriage 1. ing. Therefore, the spraying mechanism 10 can be rotated in the vertical direction as a whole. A flip-up rod 10s is fixed to the front end surface of the arm support bracket 10e. When the flip-up rod 10s is pushed down, the blowing mechanism 10 is rotated upward, and the jump-up rod shown in FIG. State. Since the lock ring 10t is provided at the tip of the flip-up rod 10s, when the lock ring 10t is hooked on the lock rod 10u, the blow-up state of the spray mechanism 10 is maintained. The lock rod 10u is fixed to the upper surface of the base angle pipe 10a by welding or the like, and extends in the traveling direction.

Details of the manually operated valve 11 are shown in FIG.
The manual operation valve 11 includes a valve 11b fixed to a support pipe 11a erected on the first carriage 1 so as to be separated from each other in the vertical direction. The valve 11b for controlling the supply of paint to the nozzle 10q is a ball valve, a butterfly valve or the like, and the operation rod 11c is fixed to the opening / closing cock, and is opened / closed by rotating the operation rod 11c by 90 ° in the horizontal direction. It is made to be able to. The operating rods 11c of the valves 11b arranged vertically are connected to each other by a connecting rod 11d at the tip so that both can be operated at once. Moreover, the connecting rod 11d can be removed, and when the connecting rod 11d is removed, it can be operated separately one by one.

  In the rail coating apparatus configured as described above, a driver is on the third carriage 3 during painting and operates at a constant speed by operating the control panel 31a. In addition, a paint supply worker gets on the second carriage 2 and appropriately switches the paint container 20 into which the suction hose 12 a is inserted while checking the remaining amount of the paint container 20. Then, a spraying operator gets on the first carriage 1 and operates the manual operation valve 11 while checking the joint of the rail R and the like. In some cases, the blowing mechanism 10 is brought into a flip-up state by the flip-up rod 10s.

  At the time of painting, as described above, the masking plate 101 is suspended from the frame 10h of the spray mechanism 10, and the masking plate 101 extends to the side of the head of the rail R. Since the nozzle 10q sprays the thermal barrier paint at the extended position of the masking plate 101, the head of the rail R is always masked by the masking plate 101 against the thermal barrier paint to be sprayed. Therefore, as a result of disposing the nozzle 10q away from the side surface of the rail R to the extent that an obstacle such as a panda roll on the side of the rail R can be avoided, the range in which the paint sprayed from the nozzle 10q spreads (one point in FIG. 3). Even if the head of the rail R is in the chain line), the head of the rail R masked with the masking plate 101 is left unpainted.
