I t f g. W e e More Device 11.1, about tl and h. The device pop. 1 and 2, unsubscribed by the fact that it contains two and a number of racks. 1054650 is the same temperature of one mountain rack and is offset relative to the racks of another p aa.

The invention relates to metallurgy, in particular, to the equipment of heating and drying furnaces, and can be used in devices for the vertical movement of piece lengthy S products (billets, pipes, etc.).

A known device for drying articles containing the mechanism for vertical movement of products installed in the working gauge, made in the form of ver-; ticking helical columns, when KOTOpbix rotates along their turns, vertically move on the rollers of the carriage with the workpiece

The disadvantages of the known device 15 are complexity, bulkiness.

Closest to the invention is a device for moving workpieces, in which two groups of racks with horizontal butts and 20 are applied.

the preparations located from one side racks. One group of racks is movable and makes a movement close to the top-level trajectory. At the same time, the removal of blanks with the butts of the supplied 25 racks from the buttles of the fixed stands, the vertical movement one step, the laying of these blanks on the next height of the row of the buttles of the fixed stands and the return of the movable stands to the original position. Then the cycle repeats 2.

The disadvantage of this device is that the blanks can be transported only in one row, which does not allow for efficient use of the working volume, reduces the productivity of PS and increases the specific fuel consumption.

The purpose of the invention is to improve the performance of the device.

The goal is achieved by the fact that in the device for the vertical movement of piece-like long products in the furnace, containing a number of vertical posts with supporting horizontal shelves, the part of the struts having 45 reciprocating vertical movements can be rotated relative to its the vertical axis, the butts are located on both sides of each rack, and the racks having the possibility of vertical reciprocating movement are installed in a row alternately with nymi uprights, at last made immobile verggikalns "eg 4 smoldering.

The device contains two or more rows of racks, with the racks of one row being shifted relative to the racks of the Deugo row

FIG. 1 shows the device, a general view; ya phage 2 - section A-A in FIG. 1; in fig. 3 is a sectional view in FIG. 1; in fig. 4 is a view of B in FIG. 1, in FIG. 5 14 - schemes of operation of the device.

The proposed device consists of racks 1 and racks 2 with shelves 3,4,5,6 for placing piece lengths 1X of products 7 on them. Racks 1 can be mixed upward or downward as well as. to rotate 9O® around its {Vertical axis on thrust bearings 8 in directions 9. RIGHTS 2 only | rotate science | 1 {main bearings 1 Bearings 8 are mounted on another frame 11, which is moved vertshlno by an eccentric mechanism 12 together with racks 1 The guide rollers 13 prevent the frame 11 from moving in a horizontal direction. The rotation of the pillars 2 is carried out through: a stack of the tooth gear mechanism 14, and the rotations of the pillars 1 by means of a gear-cutting mechanism 15.

The proposed device works as follows.

When initially positioned, the shelves are perpendicular to the plane of the racks. Piece length products 7 are stacked with the help of loading devices (not shown) on the lower shelves 3 of the second group of racks 2 (Figs. 5 and 6). Then, the first group of shooters 1, when moving up, lifts the product with the butts 4, removing them from the shelves 3 (FIG. 7), after which the pillars 2

rotated 90 and their butts 3 occupy a position in the plane of the racks parallel to the products m (Fig. 8), and the racks 1 lift the products 7 slightly higher than the butts 5 racks 2 (Fig. 9). position (Fig. 10), and when the racks 1 move down the product 7, they are placed on the poles 5 of the racks 2 (Fig. 11), STSL 1 with a further turn down rotates 90 so that their butts 4 roll back in the plane of the racks (Fig. 12) (parallel to the product m). Dropping down to the original level, the pillars 1 rotate in the opposite direction and occupy the initial position (Figs 13 and 14). . After placing the new E) edels on the ass 3 and. Psfesfesch pacing cycle of the product 7 Take a position on the height of the shelves 6 racks 2, and the product from the ass 3.

move on the butts 5 (figs. 13 and 14), etc.

in the proposed device, the product can be transported in the opposite direction (from top to bottom).

In order to make more complete use of the working space of the furnace and ensure reliable stowage of the products on the shelves, excluding the possibility of dropping products, racks of one row can be installed with mixing relative to the racks of another row.

The use of the device, for example, in furnaces or dryers allows, by carrying out multilateral heating, more use their useful volume and, consequently, increase their productivity. Use of the device for transporting billets or pipes to heat them in special combustion chambers Pass-through heating furnaces, allows to reduce fuel consumption for heating.
