Description

one

This invention relates to the manufacture of precast concrete and reinforced concrete products.

A device for forming tubular articles from concrete mixtures, comprising a movable dispenser with a guide cone 1, is known.

Closest to the present invention is a device for compacting tubular concrete products containing a feed funnel supported on the upper end of the form with clamps and centering fins, a guide cone and internal and external vibrators mounted along its vertical axis and mounted respectively in a guide cone and on the hopper 2.

A disadvantage of the known devices is the impossibility of manufacturing tubular articles with a diameter of 3 meters or more.

The purpose of the invention is to ensure the possibility of manufacturing tubular products with a diameter of 3 meters or more.

This goal is achieved by the fact that a device for compacting tubular concrete products containing a feed funnel supported on the upper end of the form with fixtures and centering ribs placed along its vertical axis.

10, the guide cone and the inner and outer vibrators mounted respectively in the guide cone and in the hopper are provided. an annular box-shaped frame fixed on the bottom of the feed funnel, mounted on it by elastic elements by an annular resonator and fixed on the internal vibrator by a synchronizer, connected with cardan shafts with external vibrators, with the centering ribs rigidly fixed on the guide cone and made 3E with radial the channels in which the cardan shafts are placed, and the external vibrators are installed “in the ring resonator. The drawing schematically shows a device for compacting tubular concrete products, a section. The device consists of a feed hopper 1 with an annular frame 2 in the lower part supported on the outer mold 3, against which it is centered with retainers in the form of conical pins k. Inside the feed funnel, along its vertical axis, is placed guide cone 5. rigidly connected with it by means of Centering ribs 6. On the ring one. frame 2 with the aid of elastic elements 7, an annular resonator 8 with external vibrators 9 mounted therein, which by means of cardan shafts 10 located in radial channels 11 of the centering ribs 6 are connected to a synchronizer 12 mounted on internal vibrator 13 with an actuator And mounted in the guiding cone 5; A device for compacting tubular concrete products works as follows. The prepared outer mold 3 together with the core 15 is mounted on the sprung frame 16, after which a device (not shown) installs the device on the outer mold 3 to center it with conical pins k, and connect the drive 1 to the gun 9 and the inner 13 vibrators to the power line (not shown) The 8-loading funnel T feeds the bucket (not shown) to the concrete mix and turns on the drive AND, as a result of which Form 3 performs torsional vibrations, which ensures fluidization of the concrete mix and its passage through the reinforcement cage c (not shown) of the product 17 The use of the proposed device for compacting tubular products from concrete mixtures makes it possible to manufacture tubular products with a diameter of 3 m or more. Apparatus of the Invention A device for compacting tubular concrete products containing a feed funnel supported on an upper end of a form with fixators and centering ribs, a guide cone and internal and external vibrators mounted along its vertical axis, and mounted respectively on a guide cone and on a feed funnel, characterized in that, in order to enable the manufacture of products with a diameter of 3 m or more, it is provided with an annular frame fixed on the bottom suit of the feed hopper, an annular resonator mounted on it using elastic elements and a synchronizer mounted on the internal vibrator connected by means of cardan shafts to external vibrators, the centering ribs being rigidly fixed on the guide cone and made of radial channels in which the cardan shafts are placed and the external vibrators are mounted on ring resonator.
