The installation consisted of a package of forms 1 with equipment 2, traverses 3 with rollers A, base beams 5 installed on the base, with guide 11, connected by bolts 7 with rollers 8 for the package, and support beams 9 located across the traverse 3. Support the beams 9 are rigidly connected to the end beams 5, and the rollers 4 of the traverse 3 are located in the guides 6 of the end beams, forming a frame, which is rotated through

The end beams 5 are made with axles 11, having flanges 12, and are

The supports 13 are rotatable around the semi-axes 11, the turning mechanism of the end beams is made of levers 14 mounted on the flanges 1.2, pivotally connected to the drive 10, the hydraulic cylinder 15 is strengthened on the levers 14 and the movable key 16 is hingedly connected to it, the key 1 interacts with spherical cutouts 17 made on the surface

Traverse 3 is connected to a drive for uniting a package of forms made in the form of electrically driven drives 18

screw stzhek 19, prikregshennvlkh to traverses 3,

To ensure synchronization of the vertical movement of the cross arms 3, the ends of the end beams 5 are mounted

chained sprockets 21 connected in pairs by synchromes 20, through which endless chains 22 are slung, each branch of which is attached to a corresponding traverse,

In order to fix the package of forms in the horizontal and vertical positions, the supports 13 are made with guides 23 in which clamps 24 are placed,

moved by the hydraulic cylinder 25 and interacting with the ramps 26 on the end beams 5.

The forms are made with brackets 27 in contact with the supporting beams 9. For fixing the molding tooling, 2 forms are made with slots 28 symmetrical about the longitudinal axis of the form, and the tooling is the 2nd corresponding conical protrusions 29 fixed on the brackets 30.

Traverses 5 are provided with service platforms 31.

The installation works as follows.

Forms 1 prepared for concreting set one another horizontally to form a package whose height should not exceed the maximum distance between the rollers 8. Then along the rollers the forms are fed into the installation, for example, by a hydraulic pusher (conventionally not shown) to the position when the brackets 27 of the forms touch the support beams 9. They turn on the electric actuators 18, which, through the screw straps 19, move the traverse 3 towards one another. The rollers 4 of the traverse 3 roll back when they are wedged in the guides 6 of the end beams 5. The movement is carried out until the bag is in a compressed state.

In this position, the geometric center of the package of forms 1 coincides with the axis of rotation of the end beams 5, since the traverse 3 passes the same distances as they approach each other.

To transfer the package of forms 1 to a vertical position during the molding period, the following operations are performed.

By means of the hydraulic cylinder 15, the key t6 is turned so that it is waxed into the spherical cut-out 17 of the flange 12 semi-axes 11 of the end beams 5. Thus, the beams are connected to the levers 14, and through them to the hydraulic cylinders 10.

Then, the end beams 5 are unfixed, for which the cylinders 25 lead to the release of the retainer 24 from the sleeve 26 of the end beams 5.

Next, hydraulic cylinders 10 through ry

chaga 14 turn the end beams 5 gg can be collected on either side of the sub trails 3 and the package of forms 1 on the don form.

25. After this, the arms 14 are returned to the initial position by the hydraulic cylinder 10, for which the hydraulic cylinder 15 removes the key 16 from the notch 17, the disconnected lever 14 with the flange 12.

Then, the paver 32 places the concrete in a vertically positioned form 1, which is supported in this position by means of the cantilevers 27 on the supporting beams -9. Concrete is compacted by any known method, such as deep vibrations. After laying and compacting the concrete mixture, heat treatment is carried out, for example, with steam introduced into the heat shirts of the mold.

After the end of heat treatment, the package of forms is shifted to a horizontal position by turning the end beams 5 through 90 ° counterclockwise, previously connecting the end beams 5 again with the levers 14 and the hydraulic cylinder 10, as oshsano.

Fix the package forms 1 in this position, and the levers 14 return to its original position. By rotating the screw pins 19, the traverse bars 3 are separated to the initial position and the package of forms 1 is placed on the rollers 8, then it is pushed out of the installation. Disassembly, demoulding, cleaning, lubricating, and assembling the molds 1 are performed, preparing them for the next molding. The package of forms 1 is served on one side and pushed out of it on the other. When this happens, the package rotates 180.

When assembling a package of forms 1, the molding tool is placed on the form pallet in a horizontal position. The conical protrusions 29 of the tooling 2 in this case enter the slots of the 28 forms, which ensures its predetermined position.

The size of the molded product can be changed by increasing or reducing the length of the bracket 30. After turning 180 °, the pallet of form 1 is located above the snap-in 2 fixed in it, and when it is lifted upwards, the conical protrusions 29 come out of the sockets 28. The product is freed from the snap-in and removed from the pallet. Since the sockets 28 are symmetrical, snap

The proposed installation allows, after concreting and heat treatment of the products, the package of forms is pushed out

and the side from where it pushed. The rotation of the frame after heat treatment of the products is carried out 90 ° clockwise. In this case, the construction of the molding tool 2 and its attachment to the mold are carried out in any known manner.

The duration of heat treatment of products in the installation can be complete to a set of stripping strength, can be shortened. Then, the stripping strength passes outside the molding plant, for which lirioryr known chambers of maturation or heat insulating caps are used.

Operations on the removal of products, tmcTKe, lubrication of forms, their assembly with reinforcement and others are carried out at technological posts and organized by any schemes: stand, aggregate, Yo-flow or conveyor, while assembling the package forms and disassembling it can be done robotic- jc and the drive for uniting the forms package is
