Description

 . I. ;

The invention relates to the production of precast concrete products and reinforced concrete.

A vibrating platform is known, containing a movable frame with a horizontal oscillation exciter on one of the platforms mounted on the base with elastic supports, the shock-absorbing of which are inclined to the horizontal plane at an angle of 7-15 l}.

A disadvantage of the known vibroplatform is the difficulty of adjusting it to a given mode of operation.

The aim of the invention is to provide ease of adjustment for a given mode of operation.

This goal is achieved by the fact that in a vibrating plate containing a movable frame 6, the causative agent of horizontal oscillations at one of the ends, mounted on the base with elastic supports, the shock absorbing parts of which are inclined to the horizontal beam at an angle of 7-15, each elastic support

It is equipped with a tilt adjustment of the damping part, made on the bidet in pairs of interlocked upper and lower segment linings with curvilinear longitudinal grooves, and placed in the last screw points.

.In FIG. 1 shows schematically the proposed vibratory cage; FIG. 2 - the same plan view; in fig. 3 - section A-A of FIG. one.

The vibratory plate consists of a movable frame 1 of a box-section, which with the help of elastic supports 2 is mounted on the base 3, with the end face of the frame 1 of the trapezoidal nest 4,

s a new polyfrequency horizontal vibration exciter 5, connected to the drive motor 6 by means of V-belt drives 7, so that the gear ratio va a to shaft 8 is 1/2 and shaft 1O to shaft I is 2/3.

On the shock-absorbing part 12 of the elastic supports 2 are installed in pairs, interlocked metal segmented lining - i curved longitudinal grooves of the pivot and fastening with the help of screw straps 14 shock-absorbing parts 12 in the range of 5-15 °. Works vibroplatform as follows. , The mold 15 is mounted on the movable frame 1 with a molded article. When the drive motor 6 is switched on an oscillator driver 5, the latter creates poly-frequency oscillations of the movable frame 1 together with the form 15 in the horizontal plane, and due to the inclination of the damping part 12 of the elastic supports 2, a vertical component of the frame 1 arm oscillates. shafts 8.9DO, 11 provides an effective part-frequency vibration effect on the molded product. The magnitude of the vertical component of part-frequency oscillations is determined by the inclination of the damping part 12 of the elastic supports 2. In the range S-ls. To change the angle of the shock-absorbing part 12 of the elastic supports 2, it is necessary to loosen the screw connections 14 and turn the metal plates 13 to the desired angle, after which the screw connections 14 are tightened. The use of the proposed invention will allow the production of high-quality concrete products with a hardness of up to 120 seconds, which in turn will lead to a reduction in cement consumption and increase the strength of the products. The time for processing the mixture is reduced by 2-3 times. Rumula Invention A vibrating platform containing a movable frame with a horizontal oscillation activator at one of the ends, mounted on the base with elastic supports, the shock-absorbing parts of which are inclined to the horizontal plane at an angle of 7-15, so that , in order to provide ease of adjustment for a given mode of operation, each elastic support is equipped with a tilt-adjusting damping part, made in the form of pairwise interlocked upper and lower segment slips with curvilinear longitudinal grooves placed in the last screw posts.
