about:

The invention relates to devices for servicing heavy steam chambers used for the heat treatment of reinforced concrete products in forms C,

The purpose of the invention is to simplify the design, improve ease of operation and reliability.

Fig, 1 shows a device, side view; figure 2 is the same, top view; on fig.Z - section aa in figure 1.

The device contains a cover 1, around the perimeter of which a partition 2 is fixed to the bottom, entering into the groove 3 GKD rozatvora mounted around the perimeter of the chamber. Rail guides 4 are run along the chamber along which the wheels 5 roll.

The mechanism for raising and lowering the covers 1 is made in the form of pivotally installed parallel levers 6 whose upper ends are connected by a common step 7 to the pneumatic cylinder 8 pivotally mounted on the lid I, and the lower ends of the levers 6 on the horizontal axes 9 are pivotally connected to the wheels 5. In the lid on the brackets 10 from both sides endless chains 11 are located. They are in permanent engagement with drive sprockets 12 and side sprockets 13. The sprockets are rotated by the electric drive 14.

The device operates as follows.

When the upper ends of the levers 6 are in an inclined position, the opening of the chamber is closed with a crush I, the partition 2 is in the groove 3 of the hydraulic lock.

flooded with water, which creates a tightness of the chamber. In order to open the chamber opening, pneumatic cylinders 8 are turned on, which rotate the levers 6 of the wheels 5 into a vertical position. The overhang 1 is raised, the partition 2 emerges from the grooves 3. The actuator 14 is turned on and the overhang 1, moving, releases the chamber opening for loading and unloading products. Upon completion of these operations, the key 1 by the actuator 14 is moved to the area of the camera opening. When the pneumatic cylinders 8 are turned on, the levers 6 are rotated from the vertical to the inclined position, the overhang 1 is lowered, the partition 2 enters the grooves 3 of the hydraulic seal, filled with water. The chamber is again sealed.
