A vibration exciter is attached to it and is connected by a flexible connection to the drive motor. The electric motor is mounted on a bracket mounted on the base with the possibility of vertical movements. In this case, the bracket is made integral in height with flanges in each of its parts, having through grooves and connecting elements placed therein. Moreover, the grooves of the flanges of one part of the bracket are perpendicular to the grooves of the other part, and the electric motor is mounted above and coaxially with the vibration exciter. 4 ill.

Description

The invention relates to the production of building materials and can be used in the molding of concrete and reinforced concrete products, for example large diameter pipes.

A known vibratory plate for forming building elements, comprising a movable and supporting frame, a vibration exciter with a drive. The causative agent of the oscillations and the electric motor of the drive are placed coaxially to each other and are connected by an elastic coupling.

Also known is a vibration pad for molding concrete products, the closest in technical essence and the achieved result to the proposed one, which contains a movable frame located on the base by means of elastic supports, a vibration exciter mounted on it, connected by a flexible connection to a drive motor mounted with the possibility of vertical movements on the bracket mounted on the base.

A disadvantage of the known constructions is their low reliability and inconvenience in maintenance.

The purpose of the invention is to improve serviceability.

In FIG. 1 shows a vibration platform; in FIG. 2-4 - flanges with grooves.

The vibrating platform for molding concrete products contains a base 1, elastic supports 2 on which a movable frame 3 is mounted. On the base 1, an L-shaped bracket is made up of two parts 4 and 5. A vibration exciter 6 is mounted on the movable frame 3, and above it coaxially on the L-shaped bracket is mounted an electric motor 7. The causative agent of vibrations 6 and

the electric motor 7 interact with each other using a flexible coupling 8. The lower part A of the L-shaped bracket is mounted on the base 1 with bolts using flanges 9, both parts 4 and 5 of the bracket are connected using bolts and flanges 10, and the electric motor 7 is attached to bracket parts 5 with bolts and flanges 11. Form 12 with concrete mixture is mounted on the movable frame Z3. The L-shaped bracket can be of a sheet construction, and, for example, a cardan shaft can be used as a flexible coupling 8. The flanges 9 of the lower part 4 of the L-shaped bracket are made with grooves 13 which, to adjust the alignment of the electric motor 7 and the vibration exciter 6, allow the bracket to be moved back and forth in a horizontal plane. The upper part 4 and the lower part 5 contain flanges 10 with grooves 14, which allow adjusting alignment by moving the brackets left and right in the horizontal plane. The upper end of the portion 5 of the bracket 4 comprises a flange 11 with grooves 15 that allow the electric motor 7 to be moved up or down. To fix the mold 12c with concrete, fixing elements can be mounted on the movable frame 3.

The device operates as follows.

A crane is mounted on a movable frame with a form 12, for example a pipe, with concrete mixture. An electric motor 7 is turned on. Through the flexible coupling 8, it transmits rotation to the vibrator 6. The latter, in turn, causes the movable frame 3 and the shape 12 located on it to oscillate in a horizontal plane.

A quick and high-quality compaction of the concrete mixture in the mold 12 takes place. After the mixture is compacted, the mold 12 is moved by a crane to the heat treatment station. The change in the position of the motor 7 relative to the exciter 6 is controlled by moving the flanges with the slots of the bracket parts.
