Description

The invention relates to the construction, in particular to devices for sandblasting and painting the inner surfaces of metal tanks, towers, storages, and the like. buildings

The aim of the invention is the expansion of operational capabilities.

FIG. 1 shows the device inside the tank; in fig. 2 is a view A of FIG. one,

Drives of rotation of the lower support and movement of the carriage with processing devices are not shown.

The contours of the tank being treated are shown in thin lines.

The device consists of an upper bearing support 1, to which is attached a unit 2 of the lower rotating support 3 located in the center of the bottom of the treated tank having a mechanical drive (not shown; the lower support 3 has a face plate 4 which can freely rotate in a vertical plane having a C-shaped groove. On the faceplate 4 a winch 5 is installed, having two reels 6 and 7 with independent mechanical drives.

In the C-shaped groove of the faceplate 4, an inclined stand 8 is installed, the ends of which are connected by a rope 9 with a drum 6 of the winch 5.

On the inclined stand 8, the carriage 10 (. Carriage drive not shown) is installed with the possibility of longitudinal movement. The drum 7 of the winch 5 is connected via the block 2 by a 1 T cable to one of the ends of the inclined stand and.

The device works as follows.

To the carriage 10 with the processing devices, the flexible pipes from the sandblasting apparatus and the pressurizing tank are attached.

Rotation of the drums 6 and 7 of the winch 5 achieves a certain position of the inclined stand 8 with the carriage 10 mounted on it. The rotation of the lower support 3 is turned on. When processing the roof or the cylindrical surface of the tanks, they are sequentially processed by the hooks of the ring surfaces. In this case, the transition to the subsequent grippers can be carried out automatically by software control 5 of the drives of the reels 6 and 7 of the winch 5.

When processing the bottom, the transfer of the carriage 10 to the next one is accomplished by automatically controlling its drive. In this case, the 0 inclined stand, installed in a horizontal position, rotates in a horizontal plane, and the carriage 10 reciprocates along the inclined 5 stand.

The treatment of the internal surfaces of the tanks may be carried out in the following sequence: sandblasting; surface painting.

These operations can be carried out simultaneously: the surface cleaned with the help of a sandblasting nozzle is painted with spray guns, mounted in a specified sequence on the carriage 10,

The installation of the device is simple and does not require special mounting devices and means of support, as follows.

The bottom support 3 and the inclined support 8 communicate and are mounted on the bottom of the tank in accordance with the drawings.

The upper support 1 with unit 2 is installed through the processing tank unit; The workers are on the overlap of the tank, the rope hanging from block 2, i t, is pressed onto the drum 7 of the winch 5 and fixed to the end of the inclined stand b.

The design of the device allows for automatic processing of the internal surfaces of tanks of any shape: spherical, pyramidal, cubic, conical, etc.
