Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a coating machine for coating poles for lighting and the like.

Conventionally, when painting poles for road lighting, etc., a work vehicle was placed next to the pole, the work vehicle was stabilized with outriggers, etc., and then the work vehicle was placed in a basket and lifted. Since painting work was carried out while raising and lowering the vehicle, lanes were reduced or wheels were blocked.

As a result, there were disadvantages such as traffic stagnation and the danger associated with working at heights.

Another disadvantage was that it took a long time to paint one pole.

SUMMARY OF THE INVENTION In view of the above-mentioned points, it is an object of the present invention to provide an automatic pole painting machine that does not reduce the number of lanes or cause traffic closures for vehicles, and shortens the working time.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

In the figure, A is a pole. In the case shown in the figure, the pole A is for illumination with a large rounded upper end bent to one side, but it may also be a straight pole for purposes other than illumination.

Reference numeral B denotes a coating machine for pole A, and this coating machine B, as shown, includes an annular frame 1 that can be assembled and disassembled and is iron-clad on the outside of the pole A, and at least three parts of the circumferential surface of this frame 1. A rocking plate 3 is mounted to rotate around a pin 2 at the minute position, and a roller 4 with a drive function is supported on the inner side of the rocking plate 3 so as to be in contact with the outer peripheral surface of the pole A. , a pressing device 5 that imparts rotatability to the rocking plate 3 so as to press the roller 4 against the pole A, and a lower end of the rocking plate 3 so that the distance between the circumferential surface of the upper end pole A is always constant. An arm 6 that supports the side, a paint spray nozzle 7 attached to the upper end of this arm 6, and a paint that is supported so that its axis is always perpendicular to the tip of a protrusion village 8 facing outward from the frame 1. A storage tank 9, a hose 10 connecting the tank 9 and the nozzle 7, and a hose 11 connected to the nozzle 7 to supply compressed air from the ground.

In the case of the above-described installation of the tank 9, the rotary punch 13 of the tank 9 is supported on one protruding member 8 via a pin 12 in the illustrated case.

In addition, the hose 10 of the nozzle 7 is connected to one tank 9, and the upper end of one long hose 11 (longer than pole A) is branched to supply compressed air to each nozzle 7. It looks like this.

Furthermore, in the illustrated case, the arm 6 is attached by supporting the end of the link 13 below the swing plate 3 via the pin 12, and by supporting the shaft 14 at the tip of the IJ link 13 and the shaft 1 of the roller 4.
5 and 6 to support the lower part of arm 6. Further, in the illustrated case, the drive of the roller 4 is transmitted from a gear 17 on the output shaft of a motor 16 to a gear 19 coaxial with the roller 4 via an intermediate gear 18.

The above-mentioned pressing device 5 has a pin 20 attached to the frame 1 in the illustrated case.
It is composed of a cylinder 21 whose end is supported via a piston 21, and a piston 23 whose distal end is connected to the swing plate 3 via a pin 22.

Note that compressed air is branched from the hose 11 and supplied to the cylinder 21 from the ground.
Furthermore, the frame 1 includes a pair of semicircular arc-shaped divided bodies 24, 24, a shaft 25 that pivots one end of the divided bodies 24, 24, and a mesh provided at the ends of the divided bodies 24, 24. It consists of a piece 26, a through hole 27 and a screw hole 28 provided to match the engaging piece 26, and a butterfly bolt 29 that is inserted into the upper through hole 27 and screwed into the screw hole 28, and is arranged above and below this. A pair of frames 1 are connected by a plate-like body 30.

The motor 16 is started and stopped using a ground-side switch (not shown) attached to the cord 31.

In addition, in the figure, 32 is a guide roller of the swing plate 3, 33 is an auxiliary roller provided on the shaft 14 so as to be in contact with the pole A, 3
4 is a spacing member for the rollers 4;
is constituted by a pipe 35 and a wheel member 36 whose inner ends are extendably and retractably iron-coupled, and a universal joint 37 which connects the pipe 35 and the ball member 36 to the plate-shaped body 30.

The coating machine according to the present invention has the above-mentioned configuration. Next, the coating method will be explained. First, the border bolt 29 is removed and the divided bodies 24, 24 are opened from each other.

After the divided bodies 24, 24 are arranged on the pole A, the divided bodies 24, 24 are closed, and the engaging piece 26 is closed.
Insert the bolt 29 from the matching through hole 27 to the screw hole 28.
Screw in.

At this time, each roller 4 is in circumscribed contact with the pole A.

Then, the pressing device 5 is activated to press the roller 4 against the pole A, and the roller 4 is moved in the upward direction of the frame 1.
When the motor 16 starts operating, the frame 1
The rise is serious. When the frame 1 reaches the upper end of the pole A (as shown in FIG. 1), the motor 16
stop operating.

Next, by operating a ground compressor to supply compressed air from the hose 11 to each nozzle 7, the tank 9
The paint inside passes through the hose 10 and is directed to the nozzle 7.
It is sprayed from pole A. When the roller 4 is driven in the downward direction of the frame 1 at the same time as the above-mentioned spraying by starting the operation of the motor 16, the frame 1 descends seriously and the ball A
Paint is sprayed sequentially from the top of the head to the bottom.

When the frame 1 reaches the lower end of the pole A, the operation of the motor 16 and the supply of compressed air are stopped.

Thereafter, the frame 1 is removed from the pole A, and the unpainted lower end portion of the pole A is painted with a brush or the like.

In addition, if the diameter of the pole A gradually increases from the upper end to the lower end as shown in the figure, the piston 23 is moved back by rotating the rocking plate 3 clockwise in FIG. 4. Therefore, there will be no problem. Also, Paul A
When the upper end is bent, the upper end of the tank 9 is rotatably supported by the protruding member 8 of the frame 1, so that the whip line of the tank 9 is always vertical.

Therefore, the paint in the tank 9 does not flow out. Since the arm 6 of the nozzle is supported by the pressure roller 4, the distance between the outer peripheral surface of the pole and the nozzle is always constant even if the diameter of the pole is different (as shown in Figure 6). )
becomes. As described above, the painting machine according to the present invention has a frame that can be assembled and disassembled and is attached to the outside of the pole, and a frame that is in pressure contact with the outer circumferential surface of the pole at a predetermined position on the periphery of the frame. A roller with a drive function installed on the frame, a nozzle supported at a predetermined position around the frame, a paint tank supported on the frame, a hose connecting the nozzle and the tank, and compressed air supplied from the ground to the nozzle. The frame consists of nine hoses, so when the frame is driven by the rollers and reaches the top of the pole, the frame is then lowered to the bottom of the pole at the same time as compressed air supply starts, and the top of the pole is The area from the top to the bottom can be painted automatically.

Therefore, unlike the conventional method of painting manually while raising and lowering the work vehicle lift, painting can be done in a short time, and there is no need to reduce the number of lanes used by work vehicles or cause traffic closures due to vehicle steel. do not.

Further, since the roller that contacts the pole is shaped like a saddle by the applied pressing force, there is no problem even with a tapered pole. Furthermore, since the paint tank is attached to the frame so that the axis of the tank is always vertical, no paint will flow out of the tank even if the upper end of the pole is bent.

Furthermore, since each nozzle is always kept at a constant distance from the outer circumferential surface of the pole, the coating is uniform and there are no areas of uneven coating.
