This is a diagram showing the operating state of a painting device that facilitates painting.

Referring to FIG. 1, the painting device 100 according to this embodiment includes guide parts 10a and 10b, a gap adjustment part 20, and a roller part 30.

The painting device 100 is a device that is supported on the rooftop of a building or structure and paints the exterior wall while being lifted and lowered by a wire and a motor, and includes a main body 80 whose portion facing the exterior wall is open.

As shown in the drawing, this main body 80 has a frame connected to it, may have all six sides open, and may be composed of a plurality of layers, but is not limited to this shape. That is, only the part facing the outer wall may be open, or the frame may be connected to the left and right sides to provide more room.

The main body 80 may be a pipe member made of metal or hard synthetic resin, and may be made of a material that enables a certain level of strength and weight reduction.

A pair of guide parts (10a, 10b) are provided on both sides of the main body (80) to face the outer wall, and one end of the guide parts (10a, 10b) is connected to the round bar (21) of the spacing adjustment part (20). , a roller unit 30 is provided at the other end.

The guide portions 10a and 10b adjust the spacing between each guide portion 10a and 10b, which is possible by the spacing adjusting portion 20. The spacing adjusting portion 20 adjusts the spacing between the guide portions 10a and 10b. It is provided at once.

This spacing adjustment unit 20 includes a round bar 21 that is rotatable without interference with the guide unit 10, and a holding means 23 for maintaining the gap between the guide units 10a and 10b, and the round bar (21) is supported on a support member, such as a support plate (40).

The round bar 21 is supported through brackets 41 provided on the support plate 40, and the brackets 41 are provided on both sides of the round bar 21 to support the round bar 21.

*At this time, the bracket 41 must be formed at a height that allows the guide parts 10a and 10b inserted into the round bar 21 to rotate at a certain angle. That is, when the guide parts 10a and 10b rotate, they collide with the support plate 40. The height of the bracket 41 is set so that the guide parts 10a and 10b can rotate as necessary.

In this embodiment, the rotation of the guide parts (10a, 10b) is for painting the outer wall, and since the angle between the guide parts (10a, 10b) and the round bar 21 is not 90 degrees, the guide parts (10a, 10b) The height of the bracket 41 can be formed so that the gap is maintained enough to allow rotation within 90 degrees.

Each guide portion 10a, 10b has a hole formed at one end, and a round bar 21 is inserted into the hole. At this time, the guide parts (10a, 10b) and the round bar 21 can rotate without interfering with each other. To this end, the first and second bearings 51 are installed between the guide parts (10a, 10b) and the round bar 21. , 52) is provided.

These first and second bearings 51 and 52 have an inner diameter equal to the outer diameter of the round bar 21, and, as in the present embodiment, may be provided inside each guide portion 10a and 10b. .

The first and second bearings 51 and 52 allow the guide portions 10a and 10b to rotate, so that when the outer wall is not smooth, the main body 80 moves along the outer wall even if it moves away from or is pushed away from the curved outer wall. By allowing the roller 33 to move, painting work can be easily performed.

The first and second bearings 51 and 52 may have jaws formed inside them to prevent the guide portions 10a and 10b from descending further from the main body 80 in a horizontal state.

As for these guide parts (10a, 10b), the distance between each guide part (10a, 10b) in the round bar (21) can be adjusted. That is, the worker can adjust the gap by moving the guide parts 10a and 10b inserted into the round bar 21 to the left and right.

That is, in the general state as shown in FIG. 2A, the gap between the guide parts 10a and 10b can be adjusted by moving the guide parts 10a and 10b left and right as shown in FIG. 2B.

In Figure 2b, the one-side guide part 10a is moved inward to reduce the gap between the guide parts 10a and 10b, so the roller rotation axis 31 becomes loose, and the roller 33 also becomes loose due to the weight and the loose roller rotation axis ( 31), it becomes stretched.

On the other hand, the guide parts (10a, 10b) must be painted with the gap maintained after adjusting the gap, and even if there is no maintenance means, the paint work is carried out due to the weight of the guide parts (10a, 10b) and the roller part (30). It is rare for the time interval to widen.

Here, in order to firmly maintain the gap between the guide parts 10a and 10b, a holding means 23, for example, a snap ring, may be provided on the outside of each guide part 10a and 10b.

When using a snap ring as the holding means 23, in order to further strengthen the guide portions 10a and 10b from moving, a groove into which the snap ring can be inserted can be further formed on the outside of the round bar 21.

Meanwhile, when adjusting the spacing of the guide parts (10a, 10b), both guide parts (10a, 10b) can be adjusted, and the guide part (10b) on one side is fixed and only the guide part (10a) on the other side is left or right. You can also adjust the gap between the two guide parts (10a, 10b) by moving to .

A roller part 30 is provided between the other ends of each guide part 10a and 10b.

The roller unit 30 includes a roller rotation shaft 31 made of a flexible material provided between the other ends of each guide section 10a and 10b, and a plurality of rollers 33 provided at regular intervals on the roller rotation shaft 31. ) includes.

Here, the roller unit 30 can be detachably coupled to the other end of the guide units 10a and 10b, and an example of this is shown in FIG. 3.

Referring to FIG. 3, both ends of the roller rotation shaft 31 of the roller unit 30 may further be provided with coupling parts 37 that are detachably coupled to the other ends of the guide parts 10a and 10b.

These coupling portions 37 are fixedly coupled to both ends of the roller rotation shaft 31, and are coupled to the other ends of the guide portions 10a and 10b by screw coupling, interference fitting, etc., and are provided to be detachable.

This has the effect of making it easy to replace the roller unit 30. That is, when the roller 33 needs to be replaced due to damage or the roller 33 needs to be changed due to a change in paint color, the roller unit 30 can be easily replaced.

The roller rotation axis 31 can be made of various flexible materials, such as tension rubber, wire, spring, etc., and the roller rotation axis 31 can be stretched depending on the shape of the outer wall surface for painting.

And when painting the outer wall of a convex surface as shown in FIG. 4b or a concave surface as shown in FIG. 4c, the roller 33 must be in close contact with the curved surface, so the gap between each guide portion 10a and 10b must be adjusted. After the roller rotation axis 31 is stretched, the main body 80 is pushed toward the outer wall, and the painting work is performed with the roller 33 in close contact with the curved surface.

That is, when the outer wall is a convex surface as shown in FIG. 4b, the gap between the guide parts 10a and 10b is reduced, the roller 33 is brought into close contact with the outer wall, and the guide parts 10a and 10b are attached to the outer wall. When pushed toward, the roller 33 comes into close contact with the entire convex surface.

In this way, the roller 33 can be provided to flexibly adhere to the curved surface by the roller rotation axis 31 made of a flexible material even on the outer wall of the convex surface without a space between the outer walls, which has the effect of facilitating painting work.

And, as shown in FIG. 4C, when the outer wall is a concave surface, the gap between the guide parts 10a and 10b is reduced, the roller 33 is brought into close contact with the outer wall, and the jig 90 shown below is pushed to push the roller 33. ) is in close contact with the entire concave surface.

Due to this, the roller 33 can be provided to flexibly adhere to the curved surface by the roller rotation shaft 31 made of a flexible material even on the outer wall of the concave surface without a space between the outer wall, which has the effect of facilitating painting work.

Here, the gap between the guide parts 10a and 10b on both sides can be adjusted, and by adjusting the gap between the guide parts 10a and 10b according to the degree of curvature of the curved surface, the roller 33 can be adjusted even if the curvature of the curved surface is different. It also has the effect of adhering closely to the painted surface.
