Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a construction method using a spraying method for lining materials such as urethane resin, and a mechanism design technology and control technology for automating the spraying work. This invention relates to an automatic silo inner wall surface lining system that sprays lining material by moving a spray gun in any direction during lining repair.

[Conventional technology]

Conventionally, the roller method has been commonly used for lining grain silos, etc. In this roller method, a worker rides on a gondola and holds a roller brush against the wall surface for a long period of time to apply the coating.

[Problem that the invention seeks to solve]

With the conventional roller construction method as described above, ■The work speed is slow and the number of workers must be increased when the construction period is short.■The work posture is unnatural on unstable scaffolding.
There are problems such as: Workers are forced to work arduously for long periods of time; and ■The thickness of the paint film is left to the worker's discretion, making it impossible to adequately check the quality. The present invention aims to solve the above-mentioned problems, and provides an automatic silo inner wall surface lining system that improves construction speed, reduces the number of workers, and stabilizes construction quality.

[Means for Solving the Problems] For this purpose, the automatic lining system for the inner wall of a silo according to the present invention is an automatic lining system for the inner wall of a silo that sprays a lining material onto the inner wall of a cylindrical silo using a spray gun. - a gondola that moves up and down inside the silo, a spray gun for spraying the lining material onto the walls, and a spray gun installed with the spray gun;
It is equipped with a table that has a moving mechanism that moves the gun parallel to the inner wall of the silo and is placed on a gondola, and a table rotation mechanism that rotates the table on the gondola. The lining material is sprayed by moving the spray gun parallel to the inner wall surface of the silo by a combination of movement, rotation of the table, and lifting and lowering of the gondola.

is driven by a rotating table drive motor 7, travels on a guide rail 8, and rotates around a rotating shaft 1) on a gondola 4. On the rotary table 3, a guide rail 5 is provided parallel to the ceiling wall 2, and a guide rail 6 is provided parallel to the side Wl.

Then, spray on each of these guide rails 5 and 6.
Slide mechanisms 9 and 10 for equipping the gun are installed. Further, on the rotary table 3, a spray pump 13 and a material pump 12 are installed for pumping the material for spraying to the spray gun. With the above configuration, the gondola 4 can be moved up and down as desired by the gondola lifting wire 14 and the gondola lifting motor 15, and apart from the up and down movement of the gondola 4, the rotary table 3 is The drive motor 7 allows for rotational movement around the rotation axis 1), and furthermore, the slide mechanisms 9 and 10 can be moved linearly along the guide rails 5 and 6 parallel to the ceiling wall 2 or the side wall 1. .

The material for spraying which is pumped further can be sprayed onto the ceiling wall 2 and the side wall 1.

Next, an example of a spraying operation will be explained. First, the gondola elevating motor 15 is driven to wind up the gondola elevating wire 14, the gondola 4 is stopped above the silo, and the lining material is sprayed onto the ceiling wall 2 by a spray gun equipped on the slide mechanism 9.

FIG. 5 shows an example of the movement pattern of the spray gun when spraying onto the ceiling wall 2.

In the movement pattern shown in Figure 5 (a1), the rotary table 3 is rotated along the guide rail 8 with the slide mechanism 9 fixed, and after one rotation, the slide mechanism 9 is controlled and the spray gun is moved to the radius of the silo. Then, by rotating the rotary table 3 again along the guide rail 8 and repeating the same operation sequentially, the lining material is sprayed over the entire surface of the ceiling wall 2.In this case, The direction of rotation of the rotary table 3 may be not only repeated as shown in the figure, but also in the same direction, or in a pattern that mixes inversion and non-inversion in units of multiple times. 5 fb) In the movement pattern shown, the ceiling wall 2 is divided into a plurality of blocks B, the rotary table 3 is fixed and the slide mechanism 9 is controlled, and the spray gun is moved in a predetermined pattern within its reachable range. lining material is sprayed block by block. The former method simplifies control because there is no setup change and most operations are unidirectional, while the latter method allows stable work because the rotary table 3 is fixed during work. It can be carried out.

After spraying the lining material on the entire surface of the ceiling wall 2, or in parallel with spraying the lining material on the ceiling wall 2, the spray gun installed in the slide mechanism 10 sprays the lining material on the side wall 1 of the silo. conduct.

C) In the illustrated movement pattern, the rotary table 3 is rotated along the guide rail 8 while the gondola 4 is fixed,
One rotation controls the slide mechanism 10 to move the spray gun a predetermined distance below the silo. Then, the rotary table 3 is rotated again along the guide rail 8 and the same operation is repeated one after another.

When the slide mechanism 10 reaches the lower end of the guide rail 6,
Gondola 4 is lowered by a predetermined distance.

By repeating the above operations, the lining material is sprayed over the entire surface of the side wall 1. Moreover, in the movement pattern shown in FIG. 6+d+, the gondola 4 and the slide mechanism 10

As is clear from the above description, according to the present invention, the spraying method is used instead of the conventional roller method, and the gondola moves up and down, the rotary table rotates, and the spray gun moves on the rotary table. Since the operation is automated through a combination of the following, the system can be managed by only one or two operators, making it possible to save labor and increase the speed of lining construction. In particular, since the spray gun is operated mechanically based on set conditions, construction quality can be stabilized compared to manual work. In addition, the safety of workers can be ensured since unstable work on the Condra scaffolding at high places is eliminated.
