The installation contains a spatial frame 1, on the middle and upper beams of which the guides 2 are installed, forming a two-meter gauge for supporting rollers 3, fixed on the side walls of the molding-heat compartments 4, which, depending on the stage of the technological process, can be arranged vertically ( when molding and steaming the product supported on two rollers 3 or horizontally (when cleaning, lubricating and reinforcing) with support on the roller 3. At the entrance of the installation, a tilter 5 is located, which establishes the molding-thermal compartments 4 nakeT to the 2 track guides of the lower gear of the frame 1. The distance between the molding-thermal compartments 4 determines the dimensions of the product. The tilter 5 is mounted on the frame 6, equipped with hydraulic cylinders 7 and rollers 8 for lifting along the guides 9 with the ropes 10 and the winch II to the second russia Above the heat forming section and compartments 4 there is a retractable belt conveyor 2 with a hopper for concrete work. Under compartments 4 there is a lifting and lowering vibrating table I3 with a lifting mechanism 14 made in the form of an eccentric with a drive and a vibrating head 15. Horizontal The vibratory cylinders 16 are mounted on the uprights of the frame 1 and are designed to move the forming-heat compartments 4 along the guides 2.

At the outlet of the installation, a lifting device 17 with a drive is located, which moves along a toothed rack 18 attached to the uprights of the frame 1.

rus frame 1, form the rut upper rus. On each side of the upper tier gauge, chain pushers 20 are located to move the compartments 4 in a horizontal position. At the exit of the installation, a mechanical brush 21 is placed for cleaning the compartments 4.

Between the inlet and outlet of the installation and between the cheater pushers 20 there is a zone for the process equipment associated with the assembly of the molding-thermal compartments, the molding, the heat treatment, the removal of the product, the cleaning, the lubrication and the laying of the reinforcement cages.

A steam distribution device 22 with two sluice chambers 23, made in the form of a metal box, is attached to the base of the vertical posts of the space frame I. A part of the box along its entire length is covered with a lid on which the longitudinal partition 24 is rigidly fixed, not reaching the bottom of the box and dividing the latter into two compartments interconnected. The box is filled with water, the level of which is somewhat higher than the lower edge of the partition 24, which serves as a water gate, isolating the closed part of the box into which steam is pumped from the atmosphere. The height of the water gate of the water gate is established when calculating the thermal regime of the compartment.

On the upper part of the box there are installed longitudinal guides 25 for feeding devices 26, made in the form of carts, on which valves 27 and distributors 28 (for several products) are installed to supply steam to the molding-thermal compartments 4. Valves 27 are wired; -shaped pipelines 29, immersed in the duct of the steam distribution device 22 so that their free end is above the surface of the sealant in the insulated part of the duct. The lock chambers 23 are a continuation of the duct of the steam distribution device 22, are filled with water with a layer of sealant and serve to introduce and discharge the released steam-feeding devices .26. The electric hoist 30 serves to return the steam feeders 26 to their original position.

55 An inclined chute 31 is provided for draining condensate to the tide.

The device works as follows.

At the entrance of the installation, the tilter 5 transfers the mold formath, but thermal compartments 4 after cleaning, lubrication and reinforcement into a vertical position with two rollers 3, and then, after connecting to the package already installed compartments 4, the vibrating dials 16 move them one step further . The conveyor 12 fills the molding thermal compartments 4 of the concrete mix, by turning the eccentrics of the lifting mechanism I4, the vibrating table 13 is lifted to the working position, then the vibrating head is activated and the concrete mixture is compacted in the molding thermal compartment 4, which is above the vibrating table 13 .

At the end of compaction, the drive of the vibrating head 15 is turned off, the lifting and lowering vibrating table returns to its original position, and the molding and thermal compartments are 4 s. by means of products with the help of distributors 28, they are connected to one of the steam intakes 26, the valve 27 is opened. In this case, the steam from the steam distribution device 22 enters the molding-thermal compartments 4 and 10

There is heat treatment of products. During the movement of products along the installation, the steam intakes 26 are moved parallel to them along the guides 25. The intakes 26 in the formwork post are disconnected from the compartments 4 and the electric hoist 30 returns them to their original position. The finished product is removed, and the free molding-thermal compartment 4 along the inclined section of the guides 2 is fed to a lifting device 17, which lifts it to the upper shaft, where compartment 4 occupies a horizontal position with four rollers 3 supported. The chain pushers 20 move the molding-thermal compartments 4 for cleaning, lubricating and reinforcing posts. When the compartment 4 advances from the cleaning and lubrication station to the reinforcement station, the lower edge of the compartment 4 cleans the metal brush 21. After the reinforcement is completed, the chain pushers 20 push the molding-thermal compartment 4 to the tilter 5, which with the help of the winch I1 lowers it onto the installation floor. The cycle is over.
