Description

  . - ..I

t. ,

The invention relates to the manufacture of precast concrete and reinforced concrete products, preferably non-pressure and low-pressure pipes.

Closest to the present invention is an installation for molding tubular concrete products containing a horizontal drive roller mounted on racks placed inside a cylindrical shape supported on it, and til side protectors.

A disadvantage of the known installation is the long duration of the manufacture of ignition products due to the impossibility of combining the processes of compaction and heat treatment.

The purpose of the invention is to reduce the time of manufacture of products by combining the processes of compaction and heat treatment.

This chain is achieved by the fact that an installation for forming tubular concrete products, containing a horizontal drive roller mounted on racks placed inside a cylindrical shape supported on it, and side guards,

equipped with additional racks with roller guides and induction heaters in the form of composite from driven rotary, horizontally movable and fixed sections of U-shaped magnetic cores with windings arranged symmetrically to the longitudinal axis of the form, and the fixed sections are mounted on protective fences and are connected with rotary sections, and one of the ends of each horizontally movable section is placed between the roller guides of the additional rack.

Nafng. D schematically shows an installation for forming tubular concrete products, a general view, a section) in FIG. 2 is a section A-A in FIG. I 8 in FIG. 3 shows a section in FIG. one; in fig. 4 is a section on BB in FIG. 3, The installation for molding tubular concrete products consists of a horizontal roller shaft I installed on the front 2 and rear 3 pillars and connected by a flexible transmission 4 to a driving motor 5, with a cylindrical mold 6 supported on the shaft 7, induction heaters consisting of the driving rotary 8, horizontal 9 and fixed 10 sections of the U-shaped magnetic cores with windings arranged symmetrically to the longitudinal shape, with fixed sections Yu mounted on the side fences x 11 and pivotally connected us with pivoting sections t2 fastened to the enclosure's II, and con-gical 1X rizontalno movable sections 9 ro pa mehtseny between guide faces 13, smontirsvannymi extra racks t4. Installation ... for molding tubular concrete products from concrete mixes as follows. A cylindrical form 6 with reinforced i-frame 15 placed in it, is mounted on a roller shaft I, then horizontal 9 is pushed out and 8 rotary 8 sections of magnetic cores with windings are turned until they are closed in order to form closed windings and turn on the drive electric motor 5 of the shaft I, the mold 6 is rotated. At the same time, the concrete is fed into the latter.
