Description

The invention relates to the manufacture of products from concrete mixtures, mainly cassette production, and can be used to finish concrete panels in a vertical position until ready for painting.

The purpose of the invention is to simplify the design.

FIG. shows the proposed installation, the general view; figure 2 - the same, end view; in FIG. 3 — troweling discs, view along arrow A in FIG. 2 in FIG. 4 — section BB in FIG. 3; on fig.Z - section bb In fig.Z; figure 6 - section GG on fig.Z.

The installation has a movable portal 1, moving along the products 2 with the help of the drive 3 on the frame 4, and the carriage 5 with the drive 6 installed on the portal and connected by a flexible element (heavy) 7 with the aid of a wheel 8 with the carriage 5

The carriage 5 is equipped with stripping devices 9, including finishing brushes 10, wetting device 1 and putty mechanisms 12 made in the form of zatiroch10.1X discs 13, consisting of spatulas 14 and elastic shells 15 equipped with pressure actuators 16 and rotation 17. In addition The carriage 5 is equipped with brackets 18 with bearings 19 bearing a shaft 20 with an eccentric 21, on which is mounted a couch 8 with a flexible link 7, and the shaft 20 is equipped with an asterisk 22, a kinematically connected transmission 23 with a driving sprocket 24 mounted on the drive shaft 25 zatirochno a disc 13 of one of the mechanisms 12 spackling. The frame of the carriage 5 has rollers 26, which is installed in the guides 27 of the portal 1, and carries a pit 28 device 28, which provides, through pipelines 29 and 30, the supply of packing mixture to the disks 13.

The frame 4 of the installation is equipped with a platform 31, and the portal-console 32 controls.

The installation works as follows.

The products 2 to be finished are mounted on the frame 4 with the help of a crane. Then, from the control panel 32 of the drive 3, the portal 1 is moved until the grinding of the 1x discs 13 into the area of the product surface. Using the buttons of the control panel, the wiper discs 13 by the presser drives 16 are pressed to the product, the first wetting device 11 is moved along the portal movement, the packing mixture is fed through pipelines 29 and 30 from the feeding device 28, and the drives for rotating the wipe discs. With the inclusion of the longitudinal course of the portal, the surface treatment of the product begins. At the same time with the inclusion of drives 17 of rotation of the disks, the carriage 5 due to the rotation of the eccentric shaft 20 from

the drive sprocket 24 performs reciprocating movements equal to a double value of the eccentric 21 and perpendicular to the movement of the longitudinal course of the portal. Since the carriage katkayus 26 is fixed in the guides 27, the horizontal oscillations from rotation of the eccentric perceives the flexible element 7, and from the vertical reciprocating movements of the carriage together with it make all movements installed on it, which improves the quality of the finish, since combined with the longitudinal movements of the portal, the carriage mechanisms perform circular ellipse-like movements. This provides the opportunity to avoid scratches on the edges of the cleaning and finishing brushes, facilitates the rubbing of putty

mixes, heats design and reliability of the installation.

When the portal moves from left to right relative to frame 4, the left wetting device 11 is turned off and the right one is turned on, which allows brushes 10 that move in front of the disks as the portal moves, and brushes following the disks, when oiled, to wet them, to produce a final finish.
