Description

one

This invention relates to the molding of products from concrete mixtures.

There are known pipe-pavers of pipe-forming installations, containing a bunker mounted on a self-propelled portal and a distribution device with profile leveling guards.

The aim of the invention is to provide the possibility of forming bell-shaped pipes and reducing the labor intensity of their manufacture. This is achieved by the fact that in the proposed paver the switchgear is made in the form of a sectional feed hopper mounted on a movable frame, the number of sections of which is equal to the number of pipes simultaneously molded by the installation. The feed hopper is provided with a copier in the form of rollers supported on the bead of the mold, and each section is equipped with an elastic barrier with elastic guide walls.

FIG. 1 shows schematically the described paver, general view; in fig. 2 is the same, view in plan; in fig. 3 - a section, on AL in f.ig. 2; in fig. 4 is a view along arrow B in FIG. 2

Self-propelled portal / mounted on rails. On “it is fixed a bunker 2 with a switchgear 5 in the form of a mounted on a movable frame 4, hingedly connected at one end with the portal /, a sectional feed bunker 5, the number of sections of which is equal to the number of pipes being molded by the installation, and the sections in the feed bin they are formed by inclined partitions 6. The feed bin is located under the feed bin with vostol nostyo vertical movements using the power cylinder 7, and each section is equipped with a vibrating screen 8 with elastic guide walls 9 and profile screeds 10. Safety flexible plates 11 are attached to the elastic guide walls. Copiers in the form of rollers 13 are attached to the side walls of the feed bin on the brackets 12, which in the working position rest on the sides of the half-molds 14.

The paver works as follows.

The concrete mixture from bukker 2 is fed into the feed bin 5. The portal is moved to the half-molds 14 with the laid reinforcement cages of the formed pipes and the switchgear 3 is lowered until the rollers 13 come into contact with the sides and half-molds. Vibrators are included in the 8 sections of the feed bin and the paver is moved along the half-molds, the concrete mix is distributed to their internal cylindrical surface, and the required configuration is given in the upper part of the concrete mix.

As the stacker continues to move, the rollers 13 run onto the lifting surfaces of the half-molds, which are open opposite their bell-shaped part, the distributor rises along them, as a result of which the volume formed by the elastic guide walls 9 and the profile equalizing flaps iO increases, therefore it enters more concrete mix. Such an increase goes to the center of the bell-shaped parts of the half-molds 14. After the semi-half-concrete concrete is completely filled, the vibratory shutters are turned off, the concrete mix ceases to flow from the hopper 5, the switchgear is lifted, and the stacker leaves.

Subject invention

The paver of the pipe forming installation, which contains a bunker installed on the self-propelled portal and a distribution device with profiled leveling shields, characterized in that the distribution device is designed as a sectional flow hopper mounted on a movable frame to reduce the labor intensity of their manufacture, the number of sections of which is equal to the number of pipes simultaneously molded by the installation, and the feed bin

provided with a copier in the form of rollers resting on the bead of the mold, and each section of it is a vibrating gate with an elastic AND guide wall.
