Description

[Detailed Description of the Invention] The present invention relates to a wall painting device. In other words, when painting the walls of buildings, steel structures, etc., it is convenient to use the device of the present invention while moving along the wall surface while combining cleaning and painting operations. Also, the installation direction of the painting machine does not match the wall surface, which causes uneven contact between the rotating brush that cleans the wall surface and the wall surface. It was devised. The present invention will be explained below based on the drawings of embodiments of the device of the present invention.

Figure 1 shows the overall outline of the device of the present invention, in which A is a painting device consisting of a paint spraying device 1 and a cleaning device 2, which is placed on a loading platform 3 facing a wall B of a structure. It is equipped so that it can be controlled from the lower control box 5 via the control line of the coating device A of the hose bundle 4, and the side frame 6 of the loading platform 3 has guide seats 7, 7, 7 on the back side. It surrounds the rails 8, 8 and is movable only in the vertical direction, and a sheave 9 is provided at the upper end of the side frame 6 and suspended by a wire 10. The aforementioned rails 8, 8 are continuously and firmly connected from the upper end to the lower end of the leader 11, and the leader 11 is connected at a connecting portion 12 so that it can be divided and connected. A head 13 is fixed to the upper end of the leader 11, pulleys 14, 14 are installed to guide the wire 10, and a base 15 is fixed to the lower end.
The leader 11 is connected to the tip of the boom 16 of the hanging machine C with a hinge 17 on the opposite side to the side where the rails 8, 8 of the leader 11 are installed, and the catch hawk 18 of the hanging machine C is connected in the upper direction. The ends are connected by pins 19, and a guide pulley 20 for the wire 10 is installed above the hinge 17. In the figure, C is a suspension machine in which the boom 16 can be divided and connected, and is a truck crane having wheels 21, 21 at the bottom and equipped with a winch, a prime mover, a driving device, etc., and 22 is a tank for paint or cleaning fluid.
Note that power, compressed air, etc. are supplied to the control box 5 from the outside.

Next, referring to FIGS. 2 and 3, the coating device A is placed on rails 23, 23, 23 on the loading platform 3 via a trolley 24, and is movable in the lateral direction of the loading platform 3 by rollers 25. and sprocket 26,
Geared motor 2 connects chain 27 to geared motor 2
The carriage 24 is configured to be moved and fixed by driving and stopping 9. A frame 31 of a coating device A is placed on the cart 24 so as to be movable in the vertical direction of the loading platform 3 via rollers 30. It is configured to move and fix A. The spraying machine 1 is housed on the upper end surface of the coating apparatus A, and includes a nozzle 35, a nozzle moving device 36, etc., and is connected to the hose bundle 4, and is connected to the control box 5 and tank 22 below. The cleaning machine 2 is housed in the space of the frame 31, and rotating brushes 37, 37 are supported at the top and bottom via shafts 38, 38, and the drive motor 39, sprockets 40, 41,
42, 43 and chains 43, 44, 44, they are integrally attached to the intermediate frame 45 in a hanging state so that they can only slide freely via sliding frames 46, 46, 46. The intermediate frame 45 includes the rotating brush 3
The 7 and 37 sides are rotatably supported 47 on the frame 31, and the drive motor 39 side is attached to the frame 3 on the lower side.
1 and the operating rod 49 of the air cylinder 48, 48, which is slidably placed on the frame 31 from the left and right sides of the frame 31.
49 in a pressed state, and press the frame 31 on the upper side.
It is guided by rollers 50 to prevent it from flying out, and the whole thing is held in place. Further, the cleaning machine 2 is fixed to an operating rod 52 of an operating rod 51 of an air cylinder 51 so that the air cylinder 51 is attached to an intermediate frame 45 and moves in and out toward the wall surface B of the structure.

When painting the wall surface B of the structure, the hanging machine C, the leader 11, the loading platform 3, the painting device A, the control box 5, the tank 22, and related equipment are gathered at the work start position of the wall surface B, as shown in Fig. 1. Assemble. next,
By operating the wheels 21, 21, boom 16, catch hawk 18, etc. of the hanging machine C, the leader 11 is grounded at the optimal position on the structure wall B, and the working state is entered. When the loading platform 3 is pulled up by the wire 10 through the sheave 9 in this system, it comes to the position indicated by the imaginary line in FIG. This state corresponds to the solid line position in FIGS. 2 and 3. Next, as shown by solid lines in FIGS. 2 and 3, the structure wall surface B and the rotating surfaces of the rotating brushes 37, 37 do not necessarily coincide. Therefore, in Fig. 3, only the cleaning device 2 is connected to one air cylinder 4.
Press the operating rod 49 of No. 8 and rotate the entire body in the direction of arrow A around the pivot point 47 so that it aligns with the direction of the wall surface B as shown by the imaginary line. Further, as shown in FIG. Press the operating rod 52 to move it in the direction of arrow B,
As shown in the imaginary line, wall surface B and rotating brushes 37, 3
The rotating brushes 37, 37 are rotated in the direction of the arrow C, and the nozzle 35 of the spraying work device 1 is also activated to slowly move the loading platform 3 while spraying paint. During the lowering, the wall surface B of the structure is cleaned and the painting is completed. In addition, the left and right position adjustment between the coating device A and the loading platform 3 is performed by a geared motor 29.
Adjustment of the longitudinal position by the chain 27 can be performed by the geared motor 34, the rack 32, and the pinion gear 33. Furthermore, in order to paint the entire wall surface B of the structure, the wheels 21, 21 of the hanging machine C are operated successively to complete the work.

As described above, the device of the present invention uses the coating device A, which is composed of the spraying device 1 and the cleaning device 2, to
The loading platform 3 is mounted on a rail to a hanging machine C so that it can move freely up and down along the wall surface B of the structure. Along the diagonal of wall B,
Because it is built into the coating device A so that it can rotate independently, cleaning work is possible even if the oblique side touches the building wall B, or if the coating device A and the building wall B do not match and are slanted. The machine 2 rotates independently along the wall B, so there is no uneven contact between the wall B and the work surface of the cleaning machine 2, and the wall B can always be cleaned in a uniform manner. Therefore, it has the advantage that the painting process can be carried out smoothly and a painted wall surface of good quality can be obtained as a whole.
